Description

Technical Field

[0001] The utility model relates to the technical field of mine support, and more specifically, to a mine support net laying device. Background Art

[0002] When constructing a mine tunnel, a support net is often laid in the tunnel to prevent the tunnel perimeter from falling and collapsing after being damaged, which may pose a danger to the workers. When the support net laying device in the prior art lays the support net in the mine tunnel, the support net is usually directly fitted to the tunnel. Due to the lack of a structure for tensioning the support net, the tension of the laid support net is poor. When the surrounding rock in the tunnel is scattered, the support net is easily deformed, thereby reducing its protective effect. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, the utility model provides a mining support net laying device, including a base 1, a first fixing rod 2 is installed on the top of the base 1, and also includes:

[0025] A tensioning structure, which is arranged on the outer surface of the first fixing rod 2;

[0026] The tensioning structure includes a movable tube 3 sleeved on the outer surface of the first fixed rod 2, two sets of first gears 4 are sleeved on the outer surface of the movable tube 3, a movable frame 5 is installed outside the first gear 4, and a fixed rod 6 is installed at the end of the movable frame 5;

[0027] Clamping components, which are arranged at both ends of the fixing rod 6;

[0028] Among them, the clamping assembly includes a movable block 12 installed at both ends of the fixed rod 6, a movable rod 13 is sleeved on one side of the movable block 12, a pressure plate 14 is installed at the end of the movable rod 13, a return spring 15 is sleeved on the outer surface of the movable rod 13, and the outer side of the movable block 12 is threadedly connected to a second threaded rod 16.

[0029] Through the cooperation between the second threaded rod 16 and the movable block 12, the second threaded rod 16 can be rotated and moved along the outer side of the movable block 12, and at the same time, through the cooperation between the second threaded rod 16 and the pressure plate 14, the movable rod 13 can be driven to move along the inside of the movable block 12, so that the support net can be clamped by the pressure plate 14. At this time, the operation of the first servo motor 7 will cause the second gear 8 to rotate, and then the cooperation between the second gear 8 and the first gear 4 can drive the first gear 4 to move along the outer surface of the movable tube 3, so that the two movable frames 5 can be driven by the first gear 4 to rotate in opposite directions to tighten the support net.

[0030] A mounting frame 11 is installed on the outer side of the movable tube 3 , a second servo motor 9 is installed on the top of the base 1 , and a first threaded rod 10 is installed on the output shaft of the second servo motor 9 .

[0031] Through the operation of the second servo motor 9, the first threaded rod 10 will rotate. At the same time, through the cooperation between the first threaded rod 10 and the mounting bracket 11, the mounting bracket 11 will drive the movable tube 3 to move up and down along the outer surface of the first fixed rod 2, thereby driving the fixed rod 6 so that the height of the support net will change, and then it is convenient to adjust the position of the fixed rod 6 according to the installation position of the tunnel.

[0032] The return spring 15 is elastically supported between the movable block 12 and the movable rod 13 .

[0033] Through the design of the reset spring 15, the movable rod 13 has good elastic reset performance. At this time, since the reset spring 15 is in a compressed state, it will apply an elastic force to the movable rod 13. Therefore, when the second threaded rod 16 releases the pressure on the pressure plate 14, it will drive the pressure plate 14 to release the pressure on the support net, thereby facilitating the disassembly of the support net.

[0034] The second threaded rod 16 is in compression contact with the pressing plate 14 .

[0035] Through the cooperation between the second threaded rod 16 and the movable block 12, the second threaded rod 16 can rotate along the outer side of the movable block 12. At the same time, through the cooperation between the second threaded rod 16 and the pressure plate 14, the second threaded rod 16 will push the pressure plate 14 to squeeze the support net.

[0036] The second gear 8 is meshingly connected with the first gear 4 .

[0037] Through the cooperation between the second gear 8 and the first gear 4, the second gear 8 will drive the two first gears 4 to rotate when rotating, thereby driving the two movable frames 5 to rotate in opposite directions, so as to facilitate the tensioning of the support net.

[0038] The first threaded rod 10 is threadedly connected to the mounting bracket 11 .

[0039] Through the cooperation between the first threaded rod 10 and the mounting frame 11, the first threaded rod 10 will drive the movable tube 3 to move up and down along the outer surface of the first fixed rod 2 through the mounting frame 11 when rotating, thereby facilitating the adjustment of the height of the support net.

[0040] Among them, the pressing plate 14 and the movable block 12 are in limited contact with the supporting net.

[0041] Through the cooperation between the movable rod 13 and the movable block 12 , the movable rod 13 can move along the inner side of the movable block 12 , thereby driving the pressure plate 14 to move, so that the support net can be clamped by the pressure plate 14 and the movable block 12 .

[0042] The working principle and use process of this utility model:

[0043] First, the staff can rotate the second threaded rod 16, and through the cooperation between the second threaded rod 16 and the movable block 12, the second threaded rod 16 can be rotated and moved along the outer side of the movable block 12, and at the same time, through the cooperation between the second threaded rod 16 and the pressure plate 14, the movable rod 13 can be driven to move along the inside of the movable block 12, so that the support net can be clamped by the pressure plate 14, and then the staff can start the first servo motor 7. At this time, the operation of the first servo motor 7 will cause the second gear 8 to rotate, and then the cooperation between the second gear 8 and the first gear 4 can drive the first gear 4 to move along the outer surface of the movable tube 3, so that the two movable frames 5 can be driven by the first gear 4 to rotate in opposite directions to tension the support net. It should be added that the first servo motor 7 used here can be suspended after the support net is tensioned to achieve locking of the support net.

[0044] Afterwards, the staff can start the second servo motor 9. The operation of the second servo motor 9 will cause the first threaded rod 10 to rotate. At the same time, through the cooperation between the first threaded rod 10 and the mounting bracket 11, the mounting bracket 11 will drive the movable tube 3 to move up and down along the outer surface of the first fixed rod 2, thereby driving the fixed rod 6 so that the height of the support net will change, and then it is convenient to adjust the position of the fixed rod 6 according to the installation position of the tunnel.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
