The strict use requirements of the wet spraying machine for mining need to be known so that the safety of users and the service life of the machine can be guaranteed.

What number of pals know that crawler excavators do no longer have a guidance wheel? so why do excavators in the marketplace have guidance wheels, and a few do now not? so nowadays xiaobian brings the answer to make a simple summary for friends. permit's now not communicate much nonsense. allow's begin state-of-the-art precis, it is still the vintage rule. if you have any questions in the system of our summary, we can communicate and discuss at any time.

Time flies, the annual vacation is about to start, and the maintenance of the hydraulic concrete placing boom machine must be done well before the holiday.
1. Maintenance of mechanical system.
1. Check whether the connecting bolts, shaft end clamps, pins, and nuts for locking the hydraulic placing boom are loose.
2. Check whether the cotter pin of the cloth machine falls off.

Hydraulic placing boom machine is a kind of terminal equipment used with concrete pump, which is suitable for the construction of high-rise buildings and large-area concrete pouring projects, which improves the quality and construction progress of concrete pouring. However, what type of hydraulic placing boom machine should be used under special construction conditions?

After working for a period of time, everyone will choose a place for vacation. Concrete wet spraying machine is a commonly used concrete wet spraying equipment. After many times of construction, it also needs to be maintained. The cured concrete wet spraying machine can not only help improve construction efficiency and shorten the construction period, but also greatly reduce the labor cost of construction.

The wet spraying machine adopts hydraulic transmission, pumping the concrete to a certain distance or to the nozzle, and then sprays the concrete onto the supporting surface with compressed air. At the same time, add an appropriate amount of accelerator to mix with the concrete at the nozzle to accelerate curing The dosage of the agent is adjusted by the metering pump.

1. Straight-line laying of pipelines: In the process of laying concrete pump pipelines, it is generally necessary to ensure that the pipeline laying lines and pouring points of the pumping equipment are straight, and the curvature is minimized as much as possible. At the same time, the laying of the concrete pump pipe support and the fixing of the pipe must be tight and reliable, and the pipe joints should be sealed and reliable, and the hose and steel pipe should not be mixed together.

1. Concrete placing booms Operators need to go through relevant technical learning and training, carefully read the operating instructions, be familiar with the working principle of the cloth machine, master the working essentials, and be in good health. They can only work after passing the inspection.

1. When the wind speed exceeds level 6, the concrete placing boom is strictly prohibited from working. When the wind speed exceeds level 4, disassembly and assembly of the concrete distributor is strictly prohibited.
2. The placing boom should keep a certain distance from the high-voltage wire relay.

Mobile & walking
The mobile hydraulic distributing machine is composed of distributing placing boom assembly, swivel support, tower body, underframe, concrete pipeline, hydraulic system, electrical system and other components.

With the continuous emergence of high-rise buildings, problems such as high wind load and high pumping have brought great difficulties to the construction of high-rise structures. Among them, the construction of concrete placing boom is a big problem.

The fine-stone concrete pump is a special type of concrete pump. This concrete pump is widely used in floor heating projects and floor construction, so it is welcomed by the majority of construction parties. So on the construction site, what are the pumping requirements of the fine stone concrete pump? Now let’s take a closer look.

In the concrete pumping construction operation, once the pipe blockage occurs, the slight blockage can be dredged by repeated forward and reverse pumps and tapping with a wooden hammer. Serious blockage may need to be removed and replaced. Therefore, prevention of pipe blockage is particularly important.

Concrete pumping equipment

Causes of blocked pipes
With the rapid development of building construction, concrete pumping equipment concrete placing boom has been widely used by construction units. However, in the concrete pouring operation, due to improper use, the phenomenon of equipment pipe blockage occurs from time to time, which not only affects the project progress, but also directly affects the project quality.

The hydraulic concrete placing boom is a kind of terminal equipment used in conjunction with the concrete pump. It is suitable for the construction of high-rise buildings and large-area concrete pouring projects. It can easily and efficiently transport the concrete to the pouring operation point, realize continuous and uniform distribution, and reduce construction costs. Improve the quality of concrete pouring and construction progress.

It is inevitable that there will be some failures when using backhoe loader to be busy for construction. Today we are explaining what is the reason for the failure of the boom.

The extensive use of backhoe loader not only saves man power and material resources, but also greatly improves work efficiency. Let’s take a look at the working principle of backhoe loader:

1 The main personnel involved in the concrete placing booms installation and disassembly must be familiar with the performance structure and characteristics of the cloth machine, skilled in technology, and have the ability to troubleshoot.
2 In the process of concrete distributor assembly and disassembly, a special person must be responsible for unified command.
3 The placing boom assembly and disassembly site should be cleaned up, and non-workers are prohibited from entering.

With the development of science and technology, the continuous expansion of the construction field, the continuous improvement of engineering construction quality requirements and the need for environmentally friendly construction, various types of wet spraying machines have emerged, including small concrete wet spraying machines, vehicle-mounted concrete wet spraying machines, and It is suitable for wet spraying concrete equipment such as concrete wet spraying trolley for large-scale projects.

In recent years, the emergence of wet spraying trolleys has solved many inconveniences in the construction process of today's projects, and has improved the efficiency of tunnel construction, coal mine construction, and slope sprayed concrete construction. The progress of China's construction machinery and equipment is largely attributed to the reform and opening up. During this period, front-end technology and foreign-funded enterprises were successively introduced.

Daily inspection of concrete placing booms.
Check whether the electrical system is working properly before operation.
Check whether the oil level of the oil tank is lower than half of the oil tank and whether the hydraulic oil is emulsified. Check whether there is leakage of hydraulic components.
Check whether the rotation direction of the oil pump is correct.
Check whether the metal structural parts are cracked, welded, twisted or deformed.

How to be lifted / jacked-up to the tower hydraulic self-climbing concrete placing booms ?

1. Before using the concrete distributor concrete placing boom, the horizontal support at 2 meters of the tower must be adjusted by the screw to make the roller tightly against the four walls.

The pumped concrete should be designed in strict accordance with the regulations, the slump should be strictly controlled, and the following principles should be followed. (1) The ratio of the large particle size of the coarse aggregate to the diameter of the conveying pipe should be: when the pumping height is below 50 m, the

Leakage caused by imperfect sealing of the pipeline will affect the quality of concrete pouring on the one hand, and reduce the slump of the concrete and the loss of pumping pressure on the other hand, which will lead to the blockage of the pipeline. The pipeline joint is not tightly sealed, the pipe clamp is loose or the sealing ring is damaged, causing slurry leakage.

The cleaning of the concrete placing boom machine is very important. It is inevitable that some impurities will be left on the concrete placing boom machine after use, which will cause the concrete placing machine to rust. It’s easy to get started when it’s time, and the concrete placing boom machine also needs to be cleaned.

The concrete placing boom is mainly composed of a main beam frame, a balance frame, a supporting seat, and a conveying pipeline.
