Description

Technical Field

[0001] This utility model relates to the technical field of roadway support devices, specifically a rapid support device for coal mine roadways crossing faults. Background Technology

[0002] During coal mining, roadways crossing faults are prone to roof fractures and surrounding rock instability, necessitating reliable support devices to ensure operational safety. Traditional coal mine roadway fault-crossing support devices have several shortcomings. Firstly, they lack effective pressure monitoring methods, making it difficult to detect roof pressure changes in real time and providing timely warnings of potential hazards, thus increasing the risk of accidents. Secondly, traditional support devices have limited adjustable support width ranges, making it difficult to adapt to roadway roofs of different widths and achieve fully enclosed support, resulting in poor support effectiveness and failing to provide comprehensive and stable support for coal mine roadway fault-crossing operations. Therefore, improvements are urgently needed. Utility Model Content

The bottom edge of the base 1 is fixedly provided with a positioning plate 14, which is fixed to the roadway floor by a ground plug.

[0025] The working principle of this utility model is as follows: This equipment is based on hydraulic drive and pressure monitoring technology. The single-cylinder hydraulic support 2 provides support force, and the hydraulic push rod 5 and hydraulic push rod 7 drive the support side plate 4 and the extended roof plate 6 to move, so as to realize the flexible adjustment of the support structure. The pressure sensor 9 monitors the pressure on the support roof plate 3 in real time, and after being processed by the controller 10, it controls the buzzer 11 to give an early warning, thereby achieving the purpose of quickly and effectively supporting the roadway and ensuring safety.

[0026] The working process of this utility model is as follows:

[0027] 1. Installation and positioning: Place the base 1 at the bottom of both sides of the tunnel and fix it to the tunnel floor using the positioning plate 14 through the ground plug to ensure that the base 1 is stable.

[0028] 2. Initial Support: Activate the single-cylinder hydraulic prop 2 to extend it upwards, causing the supporting roof plate 3 to rise and provide initial support for the roadway roof. Activate the hydraulic push rod 5, which drives the supporting side plate 4 hinged to the supporting roof plate 3 to rotate, so that it fits against the roadway side, providing support for the roadway side.

[0029] 3. Roof extension adjustment: According to the roadway width, activate hydraulic push rod 7. Hydraulic push rod 7 drives the extension roof 6 to flip and unfold, and pull out the connecting plate 8 from the other end of the extension roof 6. By adjusting the length of the pulling out of the connecting plate 8, it can be connected with the support structure on the other side. Then, use fastening bolts 13 to pass through the threaded holes 12 at the bottom of the extension roof 6 and the bottom of the connecting plate 8, and tighten the fastening bolts 13 to achieve a fixed connection between the extension roof 6 and the connecting plate 8, thus completing the full-enclosed support of the roof of roadways of different widths.
