Description

Technical Field

[0001] The utility model relates to the technical field of mountain protection nets, in particular to a mountain protection net for geological disaster management. Background Art

[0002] Mountain protection nets are various types of flexible nets, mainly wire rope nets, that are wrapped around the slopes or rocks that need to be protected to limit the weathering, peeling or destruction of the rock and soil on the mountain slope and the collapse of dangerous rocks (reinforcement function), or to control the movement of falling rocks within a certain range (enclosure function).

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the existing protective nets are mostly laid directly on the hillside when in use, but when the staff need to dismantle them, it is difficult to dismantle and difficult to recycle, thereby increasing the difficulty of the staff's work. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a mountain protection net for geological disaster management.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a mountain protection net for geological disaster control, including a rotating rod, two opposite side walls of the rotating rod are equipped with internal hollow installation boxes, the rotating rod is rotatably connected to the installation box, a protection net is wrapped around the side walls of the rotating rod, support rods are installed on the bottom surfaces of the two installation boxes, connecting rods are fixedly arranged on the side walls of the two support rods close to each other, and fixed cones are fixedly arranged on the bottom surfaces of the two support rods, and a retrieval device for retracting the protection net is installed in one of the installation boxes.

[0006] By adopting the above technical solution, when the staff needs to lay the protective net, the staff can start laying by pulling one end of the protective net. After the laying is completed, the staff needs to fix the installation box with a fixing cone. Subsequently, when the staff needs to retract the protective net, the staff needs to start the retracting device to retract the protective net, thereby reducing the difficulty of the staff to retract the protective net, thereby reducing the difficulty of the staff's work.

[0007] Furthermore, a rotation groove is formed through the upper surface of one of the installation boxes, and rotation grooves are formed through the side walls of the two installation boxes that are close to each other, the rotating rod is rotatably connected to the rotating groove, and the retracting device includes a rotating rod rotatably set in the rotating groove, a first bevel gear fixedly set on the bottom surface of the rotating rod, a first gear fixedly set on the side wall of the rotating rod, a second bevel gear meshing with the first bevel gear, and a second gear meshing with the first gear, and the second bevel gear and the second gear are fixed to each other.

[0008] By adopting the above technical solution, when the staff needs to retract the protective net, the staff needs to rotate the rotating rod, so that the first bevel gear rotates along with the rotating rod, so that the second bevel gear rotates under the action of the first bevel gear, and then the second gear rotates under the action of the second bevel gear, so that the first gear rotates under the action of the second gear, and then the rotating rod rotates under the action of the second gear, so that the protective net is wrapped around the side wall of the rotating rod, thereby reducing the difficulty for the staff to retract the protective net.

[0009] Furthermore, a mounting groove is provided on the bottom surface of the mounting box, the support rod is slidably connected to the mounting groove, a mounting rod is fixedly provided on the bottom surface of the first bevel gear, a threaded rod is fixedly provided on the upper surface of the support rod, and the threaded rod is threadedly connected to the mounting rod.

[0010] By adopting the above technical solution, when the first bevel gear rotates, the mounting rod rotates under the action of the first bevel gear, thereby causing the mounting rod and the threaded rod to rotate relative to each other, so that the support rod slides upward under the action of the threaded rod, and then the support rod slides into the mounting box. During this process, after the staff has fixed the mounting box, the bottom surface of the mounting box abuts the ground, thereby reducing the probability that the protective net cannot abut against the slope.

[0011] Furthermore, a limiting groove is formed through the inner wall of the installation groove, and a limiting strip is fixedly provided on the side wall of the support rod, and the limiting strip is slidably connected to the limiting groove.

[0014] By adopting the above technical solution, when the second gear rotates, the circular rod rotates under the action of the second gear, and then the annular block rotates under the action of the circular rod. In this process, the side wall of the annular block abuts against the inner wall of the annular groove, thereby limiting the second gear, thereby reducing the probability of shaking of the second gear and improving the stability of the device.

[0015] Furthermore, a connecting groove is provided on the bottom surface of the installation box, and the connecting rod and the connecting groove match each other.

[0016] By adopting the above technical solution, when the support rod slides into the installation box, the connecting rod slides into the connecting groove, thereby reducing the probability that the connecting rod supports the installation box.

[0017] Furthermore, handrail grooves are provided through the side walls of the two installation boxes that are away from each other.

[0018] By adopting the above technical solution, the handrail groove reduces the difficulty for the staff to carry the device body, thereby reducing the work difficulty of the staff.

[0019] Furthermore, a rocker arm is fixedly disposed on the upper surface of the rotating rod.

[0020] By adopting the above technical solution, the rocker arm reduces the difficulty for the staff to rotate the rotating rod, thereby reducing the working difficulty of the staff.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the staff needs to lay the protective net, the staff can start laying by pulling one end of the protective net. When the laying is completed, the staff needs to fix the installation box with a fixing cone. Then, when the staff needs to retract the protective net, the staff needs to start the retracting device to recycle the protective net, thereby reducing the difficulty of the staff to retract the protective net, thereby reducing the difficulty of the staff's work;

[0023] 2.

During this process, after the staff has fixed the mounting box, the bottom surface of the mounting box abuts against the ground, thereby reducing the probability that the protective net cannot abut against the slope.

The installation box 11 is a rectangular parallelepiped structure inside, and the installation box 11 is provided with two and respectively installed on two opposite side walls of the rotating rod 1, and the rotating rod 1 is rotatably connected with the installation box 11. The support rod 12 is a round rod-shaped structure, whose axis is vertical, and the support rod 12 is provided with a measure and is respectively installed on the bottom surface of the two installation boxes 11. The connecting rod 13 is a rectangular rod-shaped structure, and the connecting rod 13 is fixedly set on the side walls of the two support rods 12 close to each other. The cross section of the fixed cone 14 is triangular, and the fixed cone 14 is provided with two and respectively fixedly set on the bottom surface of the two support rods 12.

[0032] When the staff needs to lay the protective net, the staff can start laying by pulling one end of the protective net. After the laying is completed, the staff needs to fix the installation box 11 through the fixing cone 14. Subsequently, when the staff needs to retract the protective net, the staff needs to start the retracting device 3 to retract the protective net, thereby reducing the difficulty of the staff to retract the protective net, thereby reducing the difficulty of the staff's work.

[0033] A rotation groove 2 is formed through the upper surface of one of the installation boxes 11, and a rotation groove 21 is formed through the side walls of the two installation boxes 11 that are close to each other, and the rotating rod 1 is rotatably connected to the rotating groove 21. The retracting device 3 is installed in one of the installation boxes 11, and is used to retract the protective net. The retracting device 3 includes a rotating rod 31, a first bevel gear 32, a first gear 33, a second bevel gear 34 and a second gear 35. The rotating rod 31 is a round rod-shaped structure, and its axis is vertical. The rotating rod 31 is rotatably set in the rotating groove 2. The first bevel gear 32 is fixedly set on the bottom surface of the rotating rod 31, and its axis coincides with the axis of the rotating rod 31. The first gear 33 is fixedly set on the side wall of the rotating rod 1, and its axis coincides with the axis of the rotating rod 1. The second bevel gear 34 is meshed with the first bevel gear 32, and its axis is horizontal. The second gear 35 is meshed with the first gear 33, and its axis coincides with the axis of the second bevel gear 34. The second bevel gear 34 and the second gear 35 are fixed to each other.

[0034] When the staff needs to retract the protective net, the staff needs to rotate the rotating rod 31, so that the first bevel gear 32 rotates along with the rotating rod 31, so that the second bevel gear 34 rotates under the action of the first bevel gear 32, and then the second gear 35 rotates under the action of the second bevel gear 34, so that the first gear 33 rotates under the action of the second gear 35, and then the rotating rod 1 rotates under the action of the second gear 35, so that the protective net is wrapped around the side wall of the rotating rod 1, thereby reducing the difficulty for the staff to retract the protective net.

[0035] The bottom surface of the mounting box 11 is provided with a mounting groove 22, and the support rod 12 is slidably connected to the mounting groove 22. The mounting rod 4 is a round rod structure, and its axis coincides with the axis of the first bevel gear 32, and the mounting rod 4 is fixedly arranged on the bottom surface of the first bevel gear 32. The threaded rod 41 is fixedly arranged on the upper surface of the support rod 12, and its axis coincides with the axis of the mounting rod 4, and the threaded rod 41 is threadedly connected to the mounting rod 4.

[0036] When the first bevel gear 32 rotates, the mounting rod 4 rotates under the action of the first bevel gear 32, thereby causing the mounting rod 4 and the threaded rod 41 to rotate relative to each other, so that the support rod 12 slides upward under the action of the threaded rod 41, and then the support rod 12 slides into the mounting box 11. During this process, after the staff has fixed the mounting box 11, the bottom surface of the mounting box 11 abuts against the ground, thereby reducing the probability that the protective net cannot abut against the slope.

[0037] In order to improve the stability of the device, a limiting groove 23 is formed through the inner wall of the mounting groove 22, and a limiting strip 5 is fixedly arranged on the side wall of the support rod 12, and the limiting strip 5 is slidably connected with the limiting groove 23. The limiting strip 5 reduces the probability of the support rod 12 following the rotation, thereby improving the stability of the device.

[0038] A circular groove 24 is provided on the inner wall of the installation box 11, and an annular groove 25 is provided on the inner wall of the circular groove 24. The circular rod 6 is a circular rod-shaped structure, and its axis coincides with the axis of the second gear 35.

The annular block 61 is a circular ring block 61-shaped structure, and its axis coincides with the axis of the second gear 35. The annular block 61 is rotatably arranged in the annular groove 25, and the circular rod 6 and the annular block 61 are fixed to each other.

[0039] When the second gear 35 rotates, the circular rod 6 rotates under the action of the second gear 35, and then the annular block 61 rotates under the action of the circular rod 6. During this process, the side wall of the annular block 61 abuts against the inner wall of the annular groove 25, thereby limiting the second gear 35, thereby reducing the probability of shaking of the second gear 35 and improving the stability of the device.

[0040] In order to reduce the probability that the connecting rod 13 supports the installation box 11, a connecting groove 7 is provided on the bottom surface of the installation box 11, and the connecting rod 13 matches the connecting groove 7. When the support rod 12 slides into the installation box 11, the connecting rod 13 slides into the connecting groove 7, thereby reducing the probability that the connecting rod 13 supports the installation box 11.

[0041] In order to reduce the difficulty of the work of the staff, the side walls of the two mounting grooves 22 that are away from each other are penetrated with handrail grooves 8. The handrail grooves 8 reduce the difficulty of the staff to carry the device body, thereby reducing the difficulty of the staff's work.

[0042] In order to reduce the difficulty of the work of the staff, a rocker arm 9 is fixedly provided on the upper surface of the rotating rod 31. The rocker arm 9 reduces the difficulty of the staff to rotate the rotating rod 31, thereby reducing the difficulty of the staff's work.

[0043] The use principle of a mountain protection net for geological disaster management in this embodiment is as follows: when the staff needs to lay the protection net, the staff pulls one end of the protection net to start laying, and when the laying is completed, the staff needs to fix the installation box 11 through the fixing cone 14. Subsequently, when the staff needs to retract the protection net, the staff needs to rotate the rotating rod 31, so that the first bevel gear 32 rotates with the rotating rod 31, so that the second bevel gear 34 rotates under the action of the first bevel gear 32, and then the second gear 35 rotates under the action of the second bevel gear 34, so that the first gear 33 rotates under the action of the second gear 35, and then the rotating rod 1 rotates under the action of the second gear 35, so that the protection net is wound around the side wall of the rotating rod 1, thereby reducing the difficulty of the staff to retract the protection net.
