Technical Field
[0001] The utility model relates to the technical field of guide rail diverters, in particular to a front and rear reversing anti-fall device bracket. Background Art
[0002] A guide rail deflector is often used at the intersection of two guide rails on a high-altitude tower. The fall arrester worn by the operator is connected to the guide rail. As the operator moves on the high-altitude tower, the fall arrester must also move along the guide rail to ensure safe operation. When the fall arrester slides to the intersection of the two guide rails, the angle of the guide rail deflector's steering rail is adjusted to align the steering rail with one of the guide rails. This allows the fall arrester to slide from one section of the guide rail to the other, ensuring safe operation.
[0003] The current guide rail steering device can only steer in the horizontal direction and cannot be reversed in the front and rear directions. Sometimes the tower fall protection needs to reverse the fall arrester from the front to the back, but the existing technology cannot meet this requirement.
[0004] Based on this, the present application proposes a front-to-rear reversing fall arrester bracket. Utility Model Content
[0005] In order to solve the above technical problems, the utility model proposes a front and rear reversing fall arrester bracket, which can realize the front and rear reversal of the fall arrester through the reversing component, making it convenient for workers to work safely when climbing. When people transfer from the front to the back to work, closed-loop safe operation can be achieved. The steering guide rail is fixed by the limit component to ensure that the fall arrester is more stable when moving on the steering guide rail.
[0006] The technical solution to achieve the purpose of the utility model is: a front and rear reversing anti-fall device bracket, including a lower guide rail, an upper guide rail and an anti-fall device are provided on the lower guide rail, a bracket body is provided on the lower guide rail, a reversing component is provided on the bracket body, the reversing component includes a fixed frame, a rotating disk, a rotating shaft, a connecting block and a steering guide rail, the two fixed frames are fixedly connected to the bracket body, the two rotating disks are rotatably connected to the two fixed frames respectively, the rotating shaft is fixedly connected to the two rotating disks, the connecting block is fixedly connected to the rotating shaft, the steering guide rail is fixedly connected to the connecting block, and a limit assembly is provided on the bracket body.
[0007] Preferably, the reversing assembly further includes mounting holes and bolts, four of the mounting holes are opened on the bracket body, and the four bolts are respectively threadedly connected to the lower guide rail, the upper guide rail and the bracket body.
[0008] Preferably, the limiting assembly further comprises an upper limiting post and a lower limiting post, the upper limiting post is fixedly connected to the rotating disk, and the lower limiting post is fixedly connected to the rotating disk.
[0009] Preferably, the limiting assembly further includes a groove and a push plate, four of the grooves are opened on the bracket body, and the four push plates are slidably connected to the four grooves respectively.
[0010] Preferably, the limiting assembly further includes a clamping block, wherein four of the clamping blocks are fixedly connected to four push plates respectively, and the four clamping blocks are slidably connected to four grooves respectively.
[0011] Preferably, the limiting assembly further includes a spring, and two ends of the four springs are fixedly connected to the four grooves and the four push plates respectively.
[0012] Compared with the prior art, the present invention has the following significant advantages:
[0013] First: In the utility model, the reversing assembly cooperates with the steering guide rail through the mounting holes, bolts, fixing frame, rotating disk, rotating shaft, connecting block and steering guide rail. The rotating disk is rotated to drive the steering guide rail to rotate, so that the steering guide rail is first parallel to the lower guide rail, and the fall arrester is moved onto the steering guide rail. Then the rotating disk is rotated to make the steering guide rail parallel to the upper guide rail, and then the fall arrester is moved onto the upper guide rail, thereby completing the front and rear reversal of the fall arrester, facilitating safe operation of workers when climbing. When people move from the front to the back to work, closed-loop safe operation can be achieved.
[0014] Second: In the utility model, the limit assembly is coordinated by the upper limit post, groove, push plate, spring, block and lower limit post. When the upper limit post is pressed by the block, the steering guide rail is parallel to the upper guide rail. When the lower limit post is pressed by the block, the steering guide rail is parallel to the lower guide rail. The block is used to fix the upper limit post and the limit post to prevent the steering guide rail from rotating during the reversing process, thereby affecting the reversing of the fall arrester.

[0021] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] The utility model provides a front and rear reversing fall arrester bracket through improvement. The technical solution of the utility model is:
[0023] like Figure 1-Figure 3 As shown, a front-to-rear reversing fall arrester bracket includes a lower guide rail 1, an upper guide rail 2 and a fall arrester 3 are provided on the lower guide rail 1, a bracket body 4 is provided on the lower guide rail 1, the cross-section of the bracket body 4 is in a "concave" shape, a reversing component 5 is provided on the bracket body 4, the reversing component 5 includes a fixed frame 53, a rotating disk 54, a rotating shaft 55, a connecting block 56 and a steering guide rail 57, two fixed frames 53 are fixedly connected to the bracket body 4, two rotating disks 54 are respectively rotatably connected to the two fixed frames 53, the rotating shaft 55 is fixedly connected to the two rotating disks 54, the connecting block 56 is fixedly connected to the rotating shaft 55, and the steering guide rail 57 is fixedly connected to the connecting block 56. The length of the steering guide rail 57 is greater than the distance between the two fixed frames 53, and a limiting component 6 is provided on the bracket body 4.
[0024] Further, such as Figure 1 and Figure 2 As shown, the reversing assembly 5 also includes mounting holes 51 and bolts 52. Four mounting holes 51 are opened on the bracket body 4. The bracket body 4 is fixed to the lower guide rail 1 and the upper guide rail 2 by means of bolts 52. The height of the bracket body 4 is less than the height of the lower guide rail 1. The four bolts 52 are respectively threadedly connected to the lower guide rail 1, the upper guide rail 2 and the bracket body 4.
[0025] Further, such as Figure 1-Figure 3 As shown, the limit assembly 6 also includes an upper limit column 61 and a lower limit column 66. The upper limit column 61 is fixedly connected to the rotating disk 54. The upper limit column 61 and the lower limit column 66 are symmetrical with the connecting block 56 as the axis. The length of the upper limit column 61 is slightly smaller than the length of the steering guide rail 57. The lower limit column 66 is fixedly connected to the rotating disk 54.
[0026] Further, such as Figure 1-Figure 3 As shown, the limiting assembly 6 further includes grooves 62 and push plates 63 . Four grooves 62 are provided on the bracket body 4 . The length of the grooves 62 is greater than the length of the block 65 . The four push plates 63 are slidably connected to the four grooves 62 , respectively.
[0027] Further, such as Figure 2 and Figure 3 As shown, the limit assembly 6 also includes a card block 65, and the four card blocks 65 are respectively fixedly connected to the four push plates 63. The cross-section of the card block 65 is a right-angled trapezoid. The bottom of the card block 65 is used to support the upper limit column 61 and the lower limit column 66. The four card blocks 65 are respectively slidably connected in the four grooves 62.
[0028] Further, such as Figure 2 As shown, the limit assembly 6 also includes a spring 64, and the two ends of the four springs 64 are respectively fixedly connected to the four grooves 62 and the four push plates 63. When the lower limit column 66 rotates toward the block 65, it will squeeze the block 65 so that the block 65 is embedded in the groove 62. When the lower limit column 66 rotates to below the block 65, under the action of the spring 64, the block 65 is pushed to move in the direction away from the groove 62, and the block 65 is used to support the lower limit column 66.
[0029] The specific working method is: use bolts 52 to connect and fix the bracket body 4 with the lower guide rail 1 and the upper guide rail 2. When it is necessary to move the anti-fall device 3 from the lower guide rail 1 to the upper guide rail 2, rotate the rotating disk 54 to drive the rotating shaft 55 and the connecting block 56 to rotate, and the steering guide rail 57 rotates accordingly, so that the lower limit column 66 abuts the bottom of the bracket body 4. At the same time, the top of the lower limit column 66 is abutted by the clamping block 65. At this time, the steering guide rail 57 is flush with the lower guide rail 1, and the anti-fall device 3 can be pushed onto the steering guide rail 57. Then, the push plate 63 is pushed toward the direction of the rotating shaft 55, so that the block 65 moves accordingly. When the block 65 is embedded in the groove 62, the block 65 no longer abuts the lower limit post 66. At this time, the rotating disk 54 can be rotated to make the upper limit post 61 abut the bottom of the bracket body 4. At the same time, the block 65 is used to abut the top of the upper limit post 61. At this time, the steering guide rail 57 is flush with the upper guide rail 2, and the anti-fall device 3 can be moved from the steering guide rail 57 to the upper guide rail 2, thereby completing the front and rear reversal of the anti-fall device 3.
