Then, inside the first side groove, rotate the first rotating plate from the vertical state to the horizontal state along the first connecting shaft and engage the toothed groove on the support surface of the mining roadway. Next, inside the groove, rotate the second rotating plate from the horizontal state to the inclined state along the second connecting shaft. Then, inside the connecting groove, rotate the third rotating plate along the third connecting shaft to fit against the outer wall of the electric hydraulic cylinder and engage it in the middle position of the side block. Then, rotate the fastener along the outer wall of the side block to make a detachable connection between the side block and the third rotating plate, thereby keeping the second rotating plate in an inclined state. This ensures that the toothed groove on the outer wall of the bottom surface of the first rotating plate is always engaged with the support surface of the mining roadway, effectively realizing the function of the device to provide stable support using a folded lateral support structure.

Next, by moving the external connecting rod and wedge-fitting it against the inner wall of the slot, the external connecting piece can be detachably connected to the connecting block along the second connecting hole, and the adjacent electric hydraulic cylinders can be detachably connected. This effectively realizes that the device has the function of expanding from single support to group support, and the disassembly and assembly of each support component is relatively convenient. This not only improves the support efficiency of the device, but also expands the scope of application of the device.

[0017] (3) The hydraulic telescopic rod is driven to extend and slide by the operation of the electric hydraulic cylinder, which can drive the support plate to move vertically, thereby driving the roof plate to fit with the support part inside the mining roadway. At the same time, the vertical movement of the support plate and the roof plate is relatively stable under the action of the first limit rod sliding along the first limit hole. Then, the pressure relief spring makes the roof plate and the support part of the mining roadway have the function of pressure relief elastic support. Under the action of the second limit rod sliding along the second limit hole, the pressure relief elastic movement of the roof plate is relatively stable. This effectively realizes the function of pressure relief elastic support of the device, and the elastic support process is relatively stable. This not only makes the device fit and support the support part of the mining roadway at all times, but also makes the device less prone to deformation and damage when shaking inside the mining roadway, thus improving the service life of the device.

The outer wall of the first limiting rod 106 is slidably connected to the inner wall of the first limiting hole 108. The hydraulic telescopic rod 104 is driven to extend and slide by the operation of the electric hydraulic cylinder 101, thereby driving the support plate 105 to move vertically, which in turn drives the top plate 402 to fit with the support part inside the mining roadway. At the same time, the vertical movement of the support plate 105 and the top plate 402 is relatively stable under the action of the first limiting rod 106 sliding along the first limiting hole 108.

[0029] Specifically, the connecting component 3 includes a side block 301, which is disposed on the outer wall of the electric hydraulic cylinder 101. The side block 301 and the third rotating plate 208 are detachably connected by a fastener 302. By rotating the fastener 302 along the outer wall of the side block 301, the side block 301 and the third rotating plate 208 can be detachably connected, thereby keeping the second rotating plate 205 in an inclined state. This ensures that the toothed groove 209 on the outer wall of the bottom surface of the first rotating plate 202 can always engage with the support surface of the mining roadway.

[0030] Specifically, the top support assembly 4 includes a pressure relief spring 401.

The upper end of the pressure relief spring 401 is provided with a top plate 402. The outer wall of the bottom surface of the top plate 402 is provided with a second limiting rod 405. The outer wall of the second limiting rod 405 is slidably connected to the inner wall of the second limiting hole 109. The pressure relief spring 401 enables the top plate 402 to have a pressure relief elastic support function with the support part of the mining roadway. Under the action of the second limiting rod 405 sliding along the second limiting hole 109, the pressure relief elastic movement of the top plate 402 is relatively stable.

[0031] Specifically, the upper surface of the top plate 402 is provided with a second side groove 403, and the inner side wall of the second side groove 403 is provided with a first connecting hole 404. The second side groove 403 is used to engage the external connecting block 501 and, with the cooperation of the first connecting hole 404 and the external connecting member, to detachably connect adjacent top plates 402. By moving the external connecting plate and fitting it against the inner side wall of the second side groove 403, the external connecting plate and the top plate 402 can be initially engaged.

[0032] Specifically, the side-connecting assembly 5 includes a connecting block 501, which is disposed on the outer side wall of the electric hydraulic cylinder 101. The outer surface of the connecting block 501 has a slot 502, and the inner side wall of the slot 502 has a second connecting hole 503. The slot 502 is used to engage the external connecting rod and, with the cooperation of the second connecting hole 503 and the external connecting member, to detachably connect adjacent electric hydraulic cylinders 101. By moving the external connecting rod and engaging it with the inner side wall of the slot 502, and then rotating the external connecting member along the second connecting hole 503, the external connecting member and the connecting block 501 can be detachably connected, thereby enabling a detachable connection between adjacent electric hydraulic cylinders 101.

[0034] In use, firstly, the electric hydraulic cylinder 101 is moved to the desired position and erected. Then, inside the first side groove 103, the first rotating plate 202 is rotated from a vertical state to a horizontal state along the first connecting shaft 201, and the toothed groove 209 is engaged with the support surface of the mining roadway. Next, inside the groove 203, the second rotating plate 205 is rotated from a horizontal state to an inclined state along the second connecting shaft 204. Then, inside the connecting groove 206, the third rotating plate 208 is rotated and fitted against the outer wall of the electric hydraulic cylinder 101 along the third connecting shaft 207 and engaged in the middle position of the side block 301. Subsequently, the fastener 302 is rotated along the outer wall of the side block 301 to detachably connect the side block 301 and the third rotating plate 208, thereby keeping the second rotating plate 205 tilted. In an inclined state, the grooves 209 on the outer wall of the bottom surface of the first rotating plate 202 can always be engaged with the support surface of the mining roadway, effectively realizing the function of the device using a foldable lateral support structure for stable support. Furthermore, the lateral support of multiple side support components 2 ensures high support stability during the support process, making the device convenient to carry and use, and guaranteeing its support effect. Then, by moving the outer connecting plate and fitting it against the inner wall of the second side groove 403, a preliminary wedge connection can be made between the outer connecting plate and the top plate 402. Then, by rotating the outer connecting piece along the first connecting hole 404, a detachable connection can be made between the outer connecting plate and the top plate 402, thereby enabling the... A detachable connection is made between adjacent roof plates 402. Then, the external connecting rod is moved and engaged with the inner wall of the slot 502. Next, the external connecting piece is rotated along the second connecting hole 503 to detachably connect the external connecting piece to the connecting block 501. This allows for a detachable connection between adjacent electric hydraulic cylinders 101, effectively enabling the device to expand from single-unit support to group support. The assembly and disassembly of each support component are convenient, improving the support efficiency and expanding the device's application range. Finally, the electric hydraulic cylinders 101 drive the hydraulic telescopic rod 104 to extend and slide, thereby causing the support plate 105 to move vertically, which in turn moves the roof plate 402 and the mining roadway. The device fits snugly against the support parts of the mine roadway. Simultaneously, the sliding action of the first limiting rod 106 along the first limiting hole 108 stabilizes the vertical movement of the support plate 105 and the top plate 402. The pressure-relief spring 401 provides a pressure-relief elastic support function between the top plate 402 and the support parts of the mine roadway. Furthermore, the sliding action of the second limiting rod 405 along the second limiting hole 109 stabilizes the pressure-relief elastic movement of the top plate 402. This effectively realizes the pressure-relief elastic support function of the device, and the elastic support process is relatively stable. This not only ensures that the device always fits snugly against the support parts of the mine roadway, but also prevents deformation and damage when the device shakes inside the mine roadway, thus improving the service life of the device.
