[0002] In the process of underground support in domestic coal mines, a large number of prestressed mining anchor cables are used. The prestress is applied by mining anchor cable tensioning machines. The main power source of mining anchor cable tensioning machines is a pneumatic booster pump, which uses compressed air underground to boost the hydraulic oil to the working pressure. The hydraulic oil drives the tensioning jack to apply prestress to the anchor cable.

[0003] Currently, the most common pneumatic booster pumps on the market are plastic shell pneumatic booster pumps and iron shell pneumatic booster pumps. Plastic shell pneumatic booster pumps are light in weight, but have low strength and need to be protected by a metal frame. The screws on the plastic shell often fail due to thread stripping. Although the iron shell pump is strong, it is relatively heavy and inconvenient to move. Utility Model Content

The booster pump is arranged in the box body, and the air intake quick-connect connector, the filter, the angle valve, the muffler, and the manual reversing valve are arranged outside the box body. The air intake quick-connect connector is connected to the air inlet of the booster pump through the filter and the angle valve, and the air outlet of the booster pump is connected to the manual reversing valve. A refueling hole is provided on the box body, and the manual reversing valve is installed on the box body. The box body is made of stainless steel or aluminum alloy, and hydraulic oil is contained in the box body.

[0006] Furthermore, a connection pipe is provided between the filter and the angle valve, and a connecting pipe and a right-angle elbow are provided between the angle valve and the air inlet of the booster pump.

[0007] Furthermore, the connecting pipe is fixed to the box body by welding.

[0008] Furthermore, the coplanarity between the upper end surface of the connecting pipe and the upper surface of the upper cover is slightly lower than the upper surface of the upper cover.

[0009] Furthermore, the box body includes: a box body and an upper cover installed above the box body, and the upper cover is fixed to the box body by bolts.

[0010] Furthermore, handles are provided on both sides of the box body.

[0011] Furthermore, the upper cover is provided with a refueling port and is equipped with a refueling plug.

[0012] Furthermore, it also includes a liquid outlet quick plug connector, which is directly connected to the liquid outlet of the manual reversing valve.

[0013] Furthermore, a shock-resistant pressure gauge is installed on the manual reversing valve.

[0014] Furthermore, the booster pump is a plastic shell pneumatic booster pump.

[0015] The beneficial effects of the utility model are as follows: the booster pump is a plastic shell pneumatic booster pump, and the booster pump is built into a box body, so that it combines the characteristics of a plastic shell pneumatic booster pump and an iron shell pump, and has the advantages of light weight and high strength.

The booster pump 7 is arranged in the box body, and the air intake quick-connect connector 1, the filter 2, the angle valve 4, the muffler 9, and the manual reversing valve 10 are arranged outside the box body. The air intake quick-connect connector 1 is connected to the air inlet of the booster pump 7 through the filter 2 and the angle valve 4, and the air outlet of the booster pump 7 is connected to the manual reversing valve 10. A refueling hole is provided on the box body, and the manual reversing valve 10 is installed on the box body. The box body is made of stainless steel or aluminum alloy, and hydraulic oil is contained in the box body.

[0022] The pneumatic booster pump 7 is a key component of the anchor cable tensioning machine in the coal mine and is the core of the power output.

[0023] The liquid outlet of the booster pump 7 cooperates with the liquid inlet hole of the manual reversing valve 10, and the air inlet quick connector 1 is installed on the air inlet of the filter 2 and connected to the external air source;

[0024] like Figure 2 As shown, a direct connection 3 is provided between the filter 2 and the angle valve 4, and a connecting pipe 5 and a right-angle elbow 6 are provided between the angle valve 4 and the air inlet of the booster pump 7.

[0025] like Figure 2 As shown, the connecting pipe 5 is welded and fixed to the box body.

[0026] Furthermore, in this example, the coplanarity between the upper end surface of the connecting pipe 5 and the upper surface of the upper cover 8 is slightly lower than the upper surface of the upper cover 8 , which facilitates the installation of the angle valve 4 .
