Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-altitude safety protection technology, and in particular to a flexible anti-fall guide rail device. Background Technology
[0002] Flexible guide rails are made of high-strength steel wire or fiber as raw material. The high-strength steel wire or fiber is twisted together through a complex twisting process to form a thicker steel wire rope or fiber rope, which is then laid on the iron tower to ensure the safety of employees working at heights.
[0003] Currently, the mounting rings at both ends of the flexible guide rail are installed hydraulically. Traditional mounting rings do not have a proper buffer mechanism inside. When an employee falls, the employee is stopped immediately by the fall arrestor during the instantaneous descent. At the same time, the fall arrestor on the employee also pulls the flexible guide rail down instantly. There is no buffer during this process, so the employee suffers a large impact force, which is harmful to the body and has poor performance. Utility Model Content
[0004] The purpose of this invention is to provide a flexible fall arrestor rail device. The fall arrestor on the employee will pull the flexible rail down instantly. During this process, there is no cushioning, which causes the employee to suffer a strong impact force, which is harmful to the body.
[0005] To achieve the above objectives, a flexible fall arrestor guide rail device is provided, comprising: a flexible guide rail body, a lower mounting ring fixedly installed at the bottom end of the flexible guide rail body, an upper mounting ring provided at the top end of the flexible guide rail body, a buffer component provided inside the upper mounting ring, a clamping component provided on the upper mounting ring, and a fall arrestor provided on the outer wall of the flexible guide rail body.
[0006] The buffer assembly includes a buffer spring, one end of which is fixedly mounted with a slide rod. The inner wall of the slide rod is fixedly connected to the top end of the flexible guide rail body. A groove is provided inside the upper mounting ring. The other end of the buffer spring is fixedly mounted on the inner wall of the groove. A mounting plate is fixedly mounted on the outer wall of the slide rod. A second rubber ring is fixedly mounted on the outer wall of the mounting plate. A first rubber ring is fixedly mounted on the inner wall of the groove. A limit block is provided at one end of the slide rod.
[0007] According to the flexible anti-fall guide rail device, the clamping assembly includes a housing, which is fixedly installed on the side wall of the upper mounting ring, and a threaded rod is rotatably installed on the inner wall of the housing.
[0008] According to the flexible anti-fall guide rail device, the threaded rod passes through a through hole opened on the outer wall of the upper mounting ring.
[0009] According to the flexible anti-fall guide rail device, a threaded ring is threadedly installed on the outer wall of the threaded rod, and a long rod is fixedly installed on the outer wall of the threaded ring.
[0010] According to the flexible anti-fall guide rail device, a clamping block is fixedly installed at the other end of the long rod, and a travel groove is provided on the outer wall of the casing.
[0011] According to the flexible anti-fall guide rail device, the long rod is slidably connected to the inner wall of the travel groove, and a gear is fixedly installed at the other end of the threaded rod.
[0012] According to the flexible anti-fall guide rail device, a rack is fixedly installed on the outer wall of the limiting block, and the rack is meshed with a gear.
[0013] The above-mentioned solution has the following beneficial effects:
[0014] This invention incorporates a buffer component. This design effectively prevents an employee from falling. During the fall, the fall arrestor pulls the flexible guide rail body downwards. As the flexible guide rail body moves downwards, a buffer spring cushions the employee's body, increasing the time the employee spends falling and thus avoiding the impact force on the employee, preventing harm to their body. The design is highly effective.
[0015] This utility model incorporates a clamping component. This design effectively clamps the connection between the flexible guide rail body and the slide bar when the slide bar pulls the buffer spring to its longest position. This process reinforces the connection, further improving stability and resulting in good performance.
[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0025] Reference Figure 1-4 The flexible anti-fall guide rail device of this utility model includes: a flexible guide rail body 1, a lower mounting ring 2 fixedly installed at the bottom end of the flexible guide rail body 1, an upper mounting ring 3 provided at the top end of the flexible guide rail body 1, a buffer component 6 provided inside the upper mounting ring 3, a clamping component 5 provided on the upper mounting ring 3, and an anti-fall device 4 provided on the outer wall of the flexible guide rail body 1.
[0026] The buffer assembly 6 includes a buffer spring 61, which increases the time of descent to avoid a strong impact on the body during the immediate fall. A slide rod 62 is fixedly installed at one end of the buffer spring 61. The slide rod 62 is used to connect the flexible guide rail body 1 and the buffer spring 61. The inner wall of the slide rod 62 is fixedly connected to the top of the flexible guide rail body 1. A groove 64 is opened inside the upper mounting ring 3. The other end of the buffer spring 61 is fixedly installed on the inner wall of the groove 64. A mounting plate is fixedly installed on the outer wall of the slide rod 62. A second rubber ring 65 is fixedly installed on the outer wall of the mounting plate. A first rubber ring 63 is fixedly installed on the inner wall of the groove 64. The elasticity of the second rubber ring 65 and the first rubber ring 63 is used to provide secondary buffering during mutual collision. A limit block is provided at one end of the slide rod 62 to prevent the slide rod 62 from moving out of the upper mounting ring 3.
[0027] The clamping assembly 5 includes a housing 56, which is fixedly installed on the side wall of the upper mounting ring 3. A threaded rod 52 is rotatably installed on the inner wall of the housing 56. The threaded rod 52 passes through a through hole on the outer wall of the upper mounting ring 3. A threaded ring 53 is threadedly installed on the outer wall of the threaded rod 52. A long rod 54 is fixedly installed on the outer wall of the threaded ring 53. A clamping block 55 is fixedly installed at the other end of the long rod 54. A stroke groove 57 is provided on the outer wall of the housing 56. The stroke groove 57 restricts the rotation of the long rod 54, thereby restricting the threaded ring 53 and allowing the threaded ring 53 to slide on the threaded rod 52. The long rod 54 is slidably connected to the inner wall of the stroke groove 57. A gear 58 is fixedly installed at the other end of the threaded rod 52. A rack 51 is fixedly installed on the outer wall of the limiting block. The rack 51 and the gear 58 are meshed together. The meshing relationship between the rack 51 and the gear 58 converts the sliding drive source into a rotation drive source.
[0028] Working principle: When an employee falls, the fall arrestor 4 on their body self-locks onto the flexible guide rail body 1. Simultaneously, the fall arrestor 4 pulls on the flexible guide rail body 1, causing it to move. The flexible guide rail body 1, via the slide rod 62, simultaneously pulls one end of the buffer spring 61, stretching the spring. At the same time, the slide rod 62 is also in a moving state. The second rubber ring 65 on the outer wall of the slide rod 62 collides with the first rubber ring 63 on the inner wall of the slide groove 64. All of them have a certain degree of elasticity, which allows for secondary cushioning, thereby increasing the time for the employee's body to fall. When the slide bar 62 moves, it drives the rack 51 to move. The rack 51 and the gear 58 mesh with each other, causing the gear 58 to rotate synchronously. The gear 58 drives the threaded rod 52 to rotate. A threaded ring 53 is threaded on the outer wall of the threaded rod 52. When the threaded rod 52 rotates, it drives the threaded ring 53 to move. The threaded ring 53 drives the clamping block 55 to rotate through the long rod 54. The clamping block 55 clamps the connection between the flexible guide rail body 1 and the slide bar 62.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
