[0015] The present invention also provides a method for vibration monitoring of a complex and weak surrounding rock support device, comprising the vibration monitoring device for a complex and weak surrounding rock support device as described above, comprising the following steps:

[0016] The welding seat is welded to the supporting device, and the vibration sensor body is protected by the protective shell. The heat dissipation holes and dustproof net are designed to facilitate heat dissipation of the vibration sensor body in the protective shell.

[0017] One end of the first plug-in plate is located in the first slot to prevent the first limiting block from being separated from the first limiting slot, thereby fixing the protective shell relative to the mounting base. One end of the second plug-in plate is located in the second slot to prevent the second limiting block from being separated from the second limiting slot, thereby fixing the mounting base and the welding base together, thereby fixing the vibration sensor body relative to the welding base.

[0018] By driving the two first movable plates to move closer together, the first spring is compressed, and the lifting plate drives the first plug plate and the second plug plate to move, increasing the length of the second plug plate in the second slot and reducing the length of the first plug plate in the first slot, and finally causing one end of the first plug plate to disengage from the first slot, thereby releasing the restriction on the position of the first limit block;

[0019] By driving the protective shell to move, the first limiting block is disengaged from the first limiting groove, and the protective shell can be removed. At the same time, the pressing plate no longer presses the first support plate, releasing the position restriction of the first support plate, and driving the vibration sensor body to move, so that the clamping plate is disengaged from the clamping groove, and the vibration sensor body can be removed.

[0020] When it is necessary to remove the mounting base and the vibration sensor body together, the two first movable plates are driven to move away from each other, the length of the first plug-in plate in the first slot is increased, and the length of the second plug-in plate in the second slot is reduced, and finally the second plug-in plate is disengaged from the second slot, thereby releasing the limitation on the position of the second limit block, and the mounting base is driven to move away from the welding base, so that the second limit block is disengaged from the second limit slot, and the mounting base and the vibration sensor body can be removed from the welding base together.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) During operation, the welding seat is welded to the supporting device, and the vibration sensor body is protected by the protective shell. The heat dissipation holes and the dustproof net are designed to facilitate heat dissipation of the vibration sensor body in the protective shell. One end of the first plug-in plate is located in the first slot to prevent the first limit block from being separated from the first limit slot, so that the protective shell is fixed relative to the mounting seat. One end of the second plug-in plate is located in the second slot to prevent the second limit block from being separated from the second limit slot, so that the mounting seat and the welding seat are fixedly connected together, thereby fixing the vibration sensor body relative to the welding seat.

[0023] (2) By driving the two first movable plates to move closer together, the first spring is in a compressed state, and then the lifting plate drives the first plug plate and the second plug plate to move, increasing the length of the second plug plate in the second slot and reducing the length of the first plug plate in the first slot, and finally making one end of the first plug plate disengage from the first slot, releasing the restriction on the position of the first limit block, and driving the protective shell to move so that the first limit block disengages from the first limit slot, the protective shell can be removed, and at the same time, the pressing plate no longer presses the first support plate, releasing the restriction on the position of the first support plate, driving the vibration sensor body to move so that the card plate disengages from the card slot, and the vibration sensor body can be removed, which is convenient for replacement and maintenance of the vibration sensor body. When the mounting seat and the vibration sensor body need to be removed together, the two first movable plates are driven to move away from each other, increasing the length of the first plug plate in the first slot and reducing the length of the second plug plate in the second slot, and finally making the second plug plate disengage from the second slot, releasing the restriction on the position of the second limit block, and driving the mounting seat to move away from the welding seat so that the second limit block disengages from the second limit slot, so that the mounting seat and the vibration sensor body can be removed from the welding seat together;

[0024] (3) By driving the two second movable plates to move closer together, the second connecting plate drives the limiting plate to move, so that one end of the limiting plate moves out of the third limiting groove, thereby releasing the fixed relationship between the fixed block and the protective shell, and when the second movable plate moves, the slider slides relative to the first sliding groove, and the second spring is in a compressed state, thereby driving the second movable plate to move away from the protective shell, so that the dustproof net is separated from the heat dissipation hole, and the dustproof net can be removed, which is convenient for replacing and cleaning the dustproof net. When the limiting plate is separated from the third limiting groove, the second support plate moves from the second sliding groove to the support groove. Through the design of the support groove and the second support plate, the distance moved by the second connecting plate and the limiting plate is limited, and then the distance moved by the second movable plate is limited. When the second movable plate cannot move, it means that the limiting plate is separated from the third limiting groove, and there is no need to drive the two second movable plates to move closer together;

[0025] (4) When the protective shell is not installed together with the mounting base, the fixed disk is driven to move so that one end of the plug-in column is disengaged from the third slot, thereby releasing the limit on the position of the turntable. The third spring is in a stretched state, and then the threaded column is driven to rotate by the turntable. The cooperation between the threaded column and the pressing plate can make the pressing plate move, which is convenient for adjusting the position of the pressing plate. When the first limit block is inserted into the first limit slot, it is ensured that the pressing plate is in contact with one side of the first support plate to prevent the card plate from shaking in the slot, thereby preventing the vibration sensor body from shaking. When there is no need to rotate the threaded column, the fixed disk is released, and then the third spring drives the fixed disk and the plug-in column to move, so that one end of the plug-in column is inserted into the corresponding third slot, which can fix the position of the turntable and the threaded column at this time, thereby preventing the threaded column from rotating due to non-human factors.

Through the cooperation of the threaded column 40 and the pressing plate 8, the pressing plate 8 can be moved to facilitate the adjustment of the position of the pressing plate 8. When the first limit block 13 is stuck in the first limit groove 12, it is ensured that the pressing plate 8 contacts one side of the first support plate 7 to prevent the card plate 6 from shaking in the card slot 5, thereby preventing the vibration sensor body 3 from shaking. When there is no need to rotate the threaded column 40, the fixed plate 46 is released, and then the third spring 47 drives the fixed plate 46 and the plug post 45 to move, so that one end of the plug post 45 is inserted into the corresponding third slot 44, which can fix the position of the turntable 43 and the threaded column 40 at this time, and prevent the threaded column 40 from rotating due to non-human factors.
