Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to an emulsion pump truck. Background Art

[0002] The pump station is a key equipment in the coal mining face: the emulsification pump provides power for the hydraulic support, and the spray pump sprays dust when mining on the working face. As the working face advances, the pump station system needs to move with the working face at regular intervals. Since there are many pipelines in the pump station system, improving the reliability of the pump station during movement is of great significance to the safe production of coal enterprises. Using a pump station with a larger flow rate can speed up the hydraulic support and solve the constraints that limit the coal mining speed of the coal mining machine. It is an effective measure to improve the efficiency and output of coal enterprises. However, in some working faces, due to the height limit of the roof, only small pump stations with smaller flow rates can be used. The single pump capacity is small and the fluid supply capacity is low, which limits production efficiency.

[0003] Existing pump stations are all fixed on flatbed trucks to achieve underground mobility. The use of flatbed trucks increases the height of the entire equipment. Due to the height limit of the working surface, some coal mines have to use pump stations with smaller flow and volume, which cannot meet the performance requirements of tens of millions of tons of coal mining; or the mine needs to dig larger tunnels, which does not meet the requirements of green, efficient and safe mining. Taking the emulsion pump as an example, the emulsion pump and its drive motor are bolted to the base mounting frame respectively. When in use, the pump station related equipment is welded to the flatbed truck together with the base to complete the fixation. This fixing method requires coal enterprises to purchase equipment from different downstream manufacturers, and consumes a lot of time to coordinate and select equipment consistency; at the same time, coal enterprises need to weld pump stations and flatbed trucks by themselves, which is easy to cause damage to hydraulic pipelines during welding, and also wastes manpower and time. The welding deformation caused by welding is difficult to eliminate, which has a certain impact on the operation of the equipment.

[0004] In summary, the use of a flatbed truck to carry the pump station will increase the height of the entire equipment, and it is necessary to use a pump station with a smaller flow rate to reduce the height of the overall equipment, or to dig a larger tunnel, which will lead to reduced mining efficiency and increased construction costs.
