Description

Technical Field

[0001] The utility model belongs to the technical field of gas prevention and control in the gas drainage construction drill site, and particularly relates to a pneumatic control operation platform for gas drainage. Background Technique

[0002] Mine gas control mainly relies on directional gas drainage boreholes. Due to the wide coverage area and long single-hole footage of directional boreholes, it is difficult to control the gas in the boreholes during the construction process. In the gas drainage system of each drill site, the blowout prevention system during drilling mainly conducts control through measures such as the orifice five-way joint combined with the orifice blowout prevention device, blowout prevention water tank, blowout prevention airbag, standby after-drainage, and double-layer water drainer. When gas anomalies occur in the borehole, it is necessary to timely open the control valves of each blowout prevention device for regulation. Since there are many blowout prevention devices at the drilling site, manually opening each one not only takes time and effort but also consumes a long time, and gas leakage accidents often occur due to untimely opening.

[0003] The existing gas blowout prevention and warning devices in drill sites in China are relatively bulky and are controlled after the sensor senses the leaked gas, resulting in a problem of time delay. Due to unreasonable designs, other pneumatic controllers are not sensitive in operation during use, and at the same time, they can only control a single valve or a single pneumatic system separately and cannot control multiple valves or multiple systems. Content of the Utility Model

[0004] The utility model provides a pneumatic control operation platform for gas drainage to solve the problems of difficult control of gas leakage, insensitive control, slow reaction speed, and difficult operation for operators during the construction of gas drainage boreholes in the prior art.

[0005] The utility model is realized by adopting the following technical scheme: A pneumatic control operation platform for gas drainage includes a housing. An air-operated component installation panel and pneumatic connection pipe fittings are installed inside the housing. A plurality of pneumatic control valves are fixedly installed on the air-operated component installation panel. Openings corresponding to the positions of the pneumatic control valves are provided on the panel of the housing for the control rods of the pneumatic control valves to extend out. A centralized air inlet and a plurality of air outlets are arranged on the housing. The pneumatic connection pipe fittings connect the centralized air inlet and the air outlets with the pneumatic control valves.

[0006] Furthermore, the centralized air inlet and the air outlets are arranged on the side plates of the housing.

[0007] Furthermore, the pneumatic connection pipe fittings include an inlet pipe and an outlet pipe. One end of the inlet pipe is connected to the centralized air inlet, and the other end branches out to connect the air inlet holes of each pneumatic control valve. Both ends of the outlet pipe are respectively connected to the air outlet holes of the pneumatic control valves and the air outlets.

[0008] Furthermore, three pneumatic control valves are arranged side by side.

[0009] Further, the outer shell is made of stainless steel plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] It is simple to operate, sensitive in response, convenient for random installation, can reduce the labor intensity of workers, and effectively avoid the accident of gas leakage. BRIEF DESCRIPTION OF THE DRAWINGS

A pneumatic component installation panel 2 and pneumatic connection pipe fittings are installed inside the outer shell 1. A plurality of pneumatic control valves 3 are fixedly installed on the pneumatic component installation panel 2. An opening 11 is provided on the panel 14 of the outer shell 1 corresponding to the position of the pneumatic control valve 3 for the control rod 31 of the pneumatic control valve 3 to extend out. A central air inlet 12 and a plurality of air outlets 13 are provided on the outer shell 1. The pneumatic connection pipe fittings connect the central air inlet 12 and the air outlets 13 with the pneumatic control valves 3.

[0020] As Figure 2 shown, the pneumatic connection pipe fittings include an inlet pipe 4 and an outlet pipe 5. One end of the inlet pipe 4 is connected to the central air inlet 12, and the other end branches out to connect the air inlet holes of each pneumatic control valve 3.
