Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of construction equipment, and specifically relates to a special fixing device for an adjustable reflective safety belt. Background Technique
[0002] During high-altitude operations, preventing and controlling potential hazards of high-altitude operations and preventing the occurrence of falling accidents from heights are the primary prerequisites for avoiding casualties and property losses and ensuring construction safety and quality.
[0003] When the existing reflective safety belt fixing device hoists and fixes workers, it can basically only meet the vertical movement of workers. When workers need to move horizontally, they can only move horizontally by applying a horizontal force to the building surface by themselves. The movement range is limited, and the movement process increases the physical consumption of workers, reduces the working duration of a single hoisting of workers. At the same time, when workers are in a hollow layer and there is no solid around to borrow strength, they cannot move horizontally. Furthermore, during the use of traditional fixing devices, when moving horizontally, the use environment is easily limited, increasing the working intensity and difficulty of high-altitude workers.
[0004] Based on this, the present invention designs a special fixing device for an adjustable reflective safety belt to solve the above problems. Summary of the Invention

[0016] 2. The present invention sets multiple brackets and uses the movement of the remote control vehicle for alternating support, so that the remote control vehicle can always have a bracket relatively stationary with respect to the wall for support, thereby making the support effect of the remote control vehicle better and the use process more stable.
[0017] 3. The present invention enables the support legs to contact and disengage from the wall in a telescopic manner during the process of entering and leaving the straight section through mechanical linkage, making the process of the support legs approaching the wall for support and moving away from the wall to cancel support smoother, avoiding the remote control vehicle being lifted due to interference and other problems. At the same time, through the extended manner, when the support legs contact the wall, a certain pre-tightening force can be obtained, preventing the support legs from being too loose from the wall and causing the remote control vehicle to slide sideways. At the same time, relying on the mechanical linkage method, the manufacturing and use difficulty of the equipment is reduced, and the stability is higher. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner
[0026] Please refer to Figures 1-6 , the present invention provides a technical solution: an adjustable fixing device for a reflective safety belt, including a remote control vehicle 1, a cable releasing mechanism 2, a support mechanism, an orientation mechanism, and a wall 4. The remote control vehicle 1 is placed on the upper end of the wall 4. The cable releasing mechanism 2 is fixedly installed on the remote control vehicle 1. A steel cable 21 is provided in the cable releasing mechanism 2. The steel cable 21 is fixedly connected to a reflective safety belt 22. The cable releasing mechanism 2 can control the height of the reflective safety belt 22 by releasing the length of the steel cable 21. The support mechanism is arranged on the side wall of the remote control vehicle 1 and is used for longitudinally supporting the remote control vehicle 1 to prevent the remote control vehicle 1 from having a longitudinal offset. The orientation mechanism is fixedly connected to the side wall of the remote control vehicle 1 and is used for controlling the forward direction of the remote control vehicle 1.
[0027] During operation, after the worker wears the reflective safety belt 22, he is suspended in the air by the steel cable 21 for high-altitude operation. During this process, the remote control vehicle 1 provides a pulling force. Further, the steel cable 21 exerts a longitudinal pulling force on the remote control vehicle 1 through the cable releasing mechanism 2, causing the remote control vehicle 1 to have a tendency of tipping over or lateral sliding. At this time, the remote control vehicle 1 is supported by the support mechanism on the side wall, eliminating the tendency of tipping over or lateral sliding; during the worker's operation, when the worker needs to move horizontally, the worker controls the remote control vehicle 1 to move on the upper end of the wall 4 through means such as a remote control, causing the steel cable 21 to move horizontally, and then causing the worker to move horizontally.
[0028] The present invention fixes the steel cable 21 and the reflective safety belt 22 connected to the steel cable 21 through the remote control vehicle 1, solves the disadvantage that the traditional fixing method cannot be translated after fixing, resulting in inconvenient movement for workers during high-altitude operation, and a support mechanism is provided on the side wall of the remote control vehicle 1, further reducing the self-weight requirement of the remote control vehicle 1 to maintain stability, and improving the stability and reliability during the working process.
[0029] As a further solution of the present invention, the support mechanism includes two symmetrically arranged support components. Each support component includes a closed-loop slide rail 31 which is fixedly connected to the side wall of the remote control vehicle 1. Two slide bars 32 are slidably connected in the closed-loop slide rail 31. The slide bars 32 are connected to a bracket. The two slide bars 32 are jointly rotatably connected to a connecting rod 33. The closed-loop slide rail 31 is composed of a straight section at the lower end and a curved section at the upper end.
[0030] During operation, under the action of the connecting rod 33, the distance between the two slide bars 32 always remains unchanged, so that there is always a slide bar 32 in the straight part at the lower end of the closed-loop slide rail 31. Further, there is always one of the two brackets that supports the upper end of the wall 4. When the remote control vehicle 1 moves, since the bracket supports the upper end of the wall 4 and is relatively stationary with the wall 4 under the action of friction, correspondingly, during the process of the closed-loop slide rail 31 moving with the remote control vehicle 1, it moves relative to the bracket. During this process, since the two slide bars 32 are connected by the connecting rod 33, the distance between the two slide bars 32 is fixed. Further, when one slide bar 32 moves to the end of the straight part at the lower end of the closed-loop slide rail 31, it will bypass the straight part through the curved part at the upper end of the closed-loop slide rail 31 and re-enter the straight part at the other end of the closed-loop slide rail 31. Correspondingly, the bracket connected to the slide bar 32 supports the upper end of the wall 4 again to support the remote control vehicle 1, so that the remote control vehicle 1 can always have a bracket that is relatively stationary with the wall 4 for support.
[0031] By arranging multiple brackets in the present invention and using the movement of the remote control vehicle 1 for alternating support, the remote control vehicle 1 can always have a bracket that is relatively stationary with the wall 4 for support. Thus, the support effect of the remote control vehicle 1 is better and the use process is more stable.
[0032] As a further solution of the present invention, the bracket includes a first support rod 51 which is rotatably connected to the slide bar 32. The first support rod 51 is provided with an installation groove 52. A first bevel gear 53 is arranged at the upper end of the installation groove 52. The first bevel gear 53 passes through the installation groove 52 and is fixedly connected to the slide bar 32. The first bevel gear 53 meshes with a second bevel gear 54. The second bevel gear 54 is rotatably connected to the first support rod 51. The second bevel gear 54 meshes with a third bevel gear 55. The third bevel gear 55 is fixedly connected to a screw rod 56. A first slide plate 57 is slidably connected in the installation groove 52. The first slide plate 57 is connected to a support leg. The screw rod 56 passes through the first slide plate 57 and is threadedly connected to the first slide plate 57. A gear 510 is fixedly connected to the outer wall of the slide bar 32. Rack bars 511 are fixedly connected to the upper left side and the lower right side of the straight section of the closed-loop slide rail 31. The rack bars 511 can mesh with the gear 510.
[0033] During operation, the slide bars 32 in the left and right support components move in a staggered manner (that is, when one slide bar 32 in the left support component is at the left end of the straight section, one slide bar 32 in the right support component is at the middle position of the straight section). When the slide bars 32 in the support components slide in a cycle in the closed-loop slide rail 31, taking the case where the slide bar 32 (for convenience of distinction, called the left slide bar 32) is about to enter the straight section from the left end of the straight section (before reaching the left end of the straight section) as an example, the corresponding other slide bar 32 (for convenience of distinction, called the right slide bar 32) slides to the right at the rack 511 on the right side of the closed-loop slide rail 31, causing the gear 510 on the right slide bar 32 to rotate counterclockwise. Furthermore, the gear 510 drives the right slide bar 32 to rotate counterclockwise. The right slide bar 32 drives the screw 56 to rotate through the first bevel gear 53, the second bevel gear 54, and the third bevel gear 55. The screw 56 drives the first slide plate 57 to slide upward along the installation groove 52 through screw transmission, retracting the support leg, which further facilitates the subsequent movement of the first support rod 51 driven by the right slide bar 32 from the curved section to the left end of the straight section. When the right slide bar 32 moves to the right end of the straight section, the corresponding left slide bar 32 reaches the left end of the straight section. Then, the left slide bar 32 slides to the right through the left rack 511, causing the gear 510 on the left slide bar 32 to rotate clockwise. Furthermore, the gear 510 drives the left slide bar 32 to rotate clockwise. The left slide bar 32 drives the screw 56 to rotate through the first bevel gear 53, the second bevel gear 54, and the third bevel gear 55. The screw 56 drives the first slide plate 57 to slide downward along the installation groove 52 through screw transmission, extending the support leg for support. Correspondingly, due to the staggered operation of the slide bars 32 in the left and right support components, when the support leg in one support component is in the process of telescoping and cannot play a supporting role, the support leg in the other support component has completed the telescoping process and plays a supporting role. Alternating in this way, the remote control vehicle 1 is always under support.
[0034] In the present invention, through mechanical linkage, during the process of the support leg entering and leaving the straight section, in a telescoping manner, it contacts and disengages from the wall 4, making the process of the support leg approaching the wall 4 for support and moving away from the wall 4 to cancel support smoother, avoiding the remote control vehicle 1 being lifted due to interference or other problems. At the same time, through the extending method, when the support leg contacts the wall 4, a certain pre-tightening force can be obtained, preventing the remote control vehicle 1 from slipping due to the looseness between the support leg and the wall 4. At the same time, relying on the mechanical linkage method, the manufacturing and use difficulty of the equipment is reduced, and the stability is higher.
[0035] As a further solution of the present invention, the first slide plate 57 is fixedly connected with a spring 58. The spring 58 is fixedly connected with a second slide plate 59. The second slide plate 59 is slidably connected with the installation groove 52. The second slide plate 59 is fixedly connected with the support leg.
[0036] During operation, the telescopic movement of the spring 58 buffers the extension amount of the support leg, reducing the precision of equipment cooperation and avoiding the remote control vehicle 1 being tilted due to excessive extension of the support leg.
[0037] As a further solution of the present invention, the support leg includes a second support rod 61, and the second support rod 61 is fixedly connected with a chevron rod 62.
[0038] The chevron rod 62 contacts the wall 4 and plays a supporting role, enabling the support mechanism to have a transverse supporting effect while performing longitudinal support, thereby making the action of the entire support mechanism more stable and reliable.
[0039] As a further solution of the present invention, the orientation mechanism includes an adjustable telescopic rod 71. The adjustable telescopic rod 71 is fixedly connected to the side wall of the remote control vehicle 1. The adjustable telescopic rod 71 is fixedly connected with a telescopic clamping plate 72, and a guide wheel 73 is rotatably connected to the inner wall of the telescopic clamping plate 72.
[0040] During operation, adjust the length of the adjustable telescopic rod 71 and the length of the telescopic clamping plate 72 to clamp the telescopic clamping plate 72 on the side wall of the wall 4, so that the distance between the remote control vehicle 1 and the side wall of the wall 4 remains unchanged, thereby improving the stability of the remote control vehicle 1. At the same time, it also further ensures the stability of the hanging length of the steel cable 21, preventing the risk caused by the change of the distance between the remote control vehicle 1 and the side wall of the wall 4 when the remote control vehicle 1 moves, resulting in the change of the worker's height.
[0041] As a further solution of the present invention, a bracket 81 is fixedly connected to the upper end of the telescopic clamping plate 72, and a runner 82 is rotatably connected to the upper end of the bracket 81. The steel cable 21 is lowered around the runner 82.
[0042] During operation, the steel cable 21 is lowered through the runner 82 to avoid the steel cable 21 being worn due to friction with the wall 4 when the steel cable 21 moves horizontally, thereby affecting the strength and service life of the steel cable 21.
[0043] As a further solution of the present invention, a rubber pad is fixedly connected to the lower end of the chevron rod 62.
[0044] The rubber pad reduces the wear of the chevron rod 62 and improves the service life of the equipment.
