Description

Technical Field

[0001] The utility model relates to the technical field of slopes, and particularly relates to a high-stability slope. Background Technique

[0002] A slope refers to a slope with a certain gradient made on both sides of a roadbed to ensure the stability of the roadbed.

[0003] For example, a slope protection net provided by a Chinese utility model patent with the publication number of CN218291991U includes steel columns. The number of the steel columns is two, and the two steel columns are symmetrically arranged left and right. The bottom of the steel column is fixedly connected with an anchor rod. The top and bottom of the inner side of the steel column are both fixedly connected with an outer shell. A connecting block is arranged at the bottom of the inner cavity of the outer shell. A positioning hole is opened on the outer side of the top of the connecting block. A positioning column is arranged in the inner cavity of the positioning hole. The top of the positioning column is fixedly connected with a connecting plate. The utility model provides a slope protection net. During assembly, first, the connecting rod is pulled upward through a pulling block. The connecting rod drives the connecting plate and the spring to move upward. The connecting plate drives the sliding sleeve to slide on the sliding rod. At the same time, the connecting plate drives the positioning column to move upward. At this time, the connecting block is inserted into the outer shell. The first limiting block and the second limiting block in the outer shell limit and insert the connecting plate. Then the pulling block is released.

[0004] In order to prevent the stones on the slope from falling, it is necessary to protect the slope. However, in the existing technology, most of them protect the slope through a protection net. When the loose stones roll and impact on the protection net, in order to eliminate the potential safety hazards brought by the rolling stones, it is necessary to take out the rolling stones from the protection net. However, due to the impact of the rolling stones on the protection net, the protection net will undergo plastic deformation (i.e., deformation that cannot be restored after the external force is removed), resulting in the overall structure of the protection net being difficult to return to its original state, making the protection net extremely loose, thereby reducing the stability of the slope protection. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-stability slope to solve the problem of poor stability of the protection net proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-stability slope includes a slope body, on which a protection net body is arranged;

[0007] The winding assembly includes a pair of fixed column blocks, a winding groove, a spring groove, a winding rod, a clockwork spring, an ear plate and a threaded rod. The pair of fixed column blocks are symmetrically arranged on both sides of the protective net body. A winding groove is formed in the fixed column block. A spring groove is formed on one side of the winding groove. The winding rod is rotatably arranged in the winding groove. One end of the winding rod passes through the winding groove and extends into the spring groove, and the other end is connected to the fixed column block. The end of the protective net body passes through the fixed column block and is wound around the circumferential surface of the winding rod. The clockwork spring is sleeved on the winding rod, and both ends of the clockwork spring are fixedly connected to the inner wall of the spring groove and the circumferential surface of the winding rod respectively. At least one ear plate is fixedly arranged on the circumferential surface of the fixed column block.

A movable groove is formed on the other side of the winding groove, and the other end of the winding rod passes through the winding groove and extends into the movable groove. The fixed circular block is fixedly connected to the other end of the winding rod. A plurality of limiting blocks A are fixedly arranged in an annular array on the side of the fixed circular block away from the winding rod. The movable circular block is arranged in the movable groove. A plurality of limiting blocks B are fixedly arranged in an annular array on the side of the movable circular block close to the fixed circular block.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. By setting up the winding component, during use, first, fix the ear plate on the fixed column block on one side of the protection net body to the slope body through the threaded rod. Then, pull the fixed column block on the other side of the protection net body to unwind the protection net body on the winding rod, causing the winding rod to rotate in the winding groove, making the clockwork spring contract under force, and gradually increasing the distance between the fixed column blocks on both sides of the protection net body until the fixed column block on the other side of the protection net body moves to a suitable position. At this time, fix the ear plate on this side of the fixed column block to the slope body through the threaded rod. Compared with the prior art, the structure layout of the present utility model is simple and reasonable, easy to use, can adjust the slack of the protection net body, and has a high stability for protecting the slope from rolling stones.

[0016] 2. By setting up the limiting component, when the protection net body is slack, pull the moving square rod on the fixed column block on any one side of the protection net body, causing the moving square rod to move, making the movable round block slide in the movable groove, and making the return spring contract under force until the limiting block B no longer contacts the limiting block A. At this time, the clockwork spring is no longer under force and starts to expand, causing the winding rod to rotate in the winding groove in the opposite direction, winding up the protection net body until the protection net body cannot be wound up. At this time, release the moving square rod, the return spring is no longer under force and starts to expand, causing the movable round block to slide in the movable groove in the opposite direction until the limiting block B is in snap connection contact with the limiting block A.
