[0002] When staff perform high-altitude work in a substation, they must wear a safety belt for safety reasons, and the safety belt during the work must meet the usage requirement of hanging high and using low. Therefore, the hook of the safety belt needs to be suspended above the working position through a fixed bracket to meet the working height requirement.

[0003] The existing safety belt fixed brackets can only meet the installation conditions of one high-altitude working station. For example, when overhauling a knife switch, it is installed on a square channel steel (a long strip-shaped cuboid structure / horizontal direction), and when overhauling a transformer, it is installed on a circular bushing riser (a cylindrical structure / vertical or slightly inclined vertically). This kind of point installation method limits the installation position when the fixed bracket is in use, and at the same time limits the working range of the staff. When exceeding the working range, the fixed bracket can only be moved and reinstalled, which is very inconvenient. Moreover, the existing safety belt fixed brackets have a single function and cannot meet the usage needs of different working scenarios. To solve the above problems, it is necessary to develop a safety auxiliary tool suitable for high-altitude work in substations. Summary of the Invention

Detailed implementation mode

[0023] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present invention provides a safety auxiliary tool suitable for substation climbing operations, including a full-body safety belt, a fastening block 1, a safety rope 13, and tight rope devices A2 and B3 respectively installed at both ends of the fastening block. The tight rope device A2 includes a tightening operation part A201 and a fixing part A202, and the tight rope device B3 includes a tightening operation part B301 and a fixing part B302. The tightening operation part A201 and the fixing part A202 are respectively installed on one side of the fastening block 1 in the up and down directions, and the fixing part B302 and the tightening operation part B301 are respectively installed on the other side of the fastening block 1 in the up and down directions. A vertical pole 5 is provided on one side of the fastening block 1 between the tight rope device A2 and the tight rope device B3.

[0025] Specifically, the fastening block 1, the vertical pole 5, the tight rope device A2 and the tight rope device B3 form a basic fixing bracket. Due to the softness and conformability of the tight rope devices A2 and B3 themselves, when the fixing bracket is installed, it is suitable for both bundling and fixing with the square channel steel 21 and bundling and fixing with the circular sleeve lifting seat 20, improving the installation adaptability of the fixing bracket; at the same time, the two sets of tight rope devices are provided, which are convenient for mutual cooperation. They can not only perform two horizontal bundlings up and down on the circular sleeve lifting seat 20 in the vertical or slightly inclined vertical direction, but also perform two longitudinal bundlings left and right on the horizontal square channel steel 21, with convenient use and firm bundling.

[0026] Among them, the rope tightener adopts the existing technology. The rope tightener is specifically used for tightening and fixing ropes and is usually used for hoisting, towing, and fixing heavy objects. The rope tightener can be understood as consisting of three parts: a tightening operation part at the front end, a rope in the middle, and a fixing part at the rear end; among them, the tightening operation part is the core operation area of the rope tightener, including components such as a handle, a ratchet, and a pawl. When in use, the handle is operated to drive the ratchet to rotate, thereby winding the rope, realizing the tightening of the rope, and then using the one-way locking of the ratchet and the pawl to keep the rope in a tensioned state to achieve the purpose of fixing; among them, the rope can be retracted and released. When not in use, the rope can be wound around the tightening operation part. When in use, the ratchet is controlled to reverse by operating components such as the handle to release the rope from the tightening operation part; among them, the fixing part is mainly a fixing point for temporarily fixing the released end of the rope. For example, when the released end of the rope is a rope hook, the fixing part can be a fixing ring, and the rope hook is hung on the fixing ring and tightened to complete the fixing.

[0027] An electric telescopic rod 10 with a working shaft 1001 facing downward is installed at the top of the vertical rod 5. Due to limited space, the electric telescopic rod 10 is a miniature one. A groove 9 with an opening facing outward is provided on the vertical rod 5 below the working shaft 1001 of the electric telescopic rod 10. A working limit hole 17 that matches the working shaft 1001 of the electric telescopic rod 10 to pass through the upper and lower side walls of the groove 9 when the working shaft 1001 works is provided at the lower end of the working shaft 1001 of the electric telescopic rod 10 on the vertical rod 5. Suspension rings 12 are provided at both ends of the safety rope 13. When in use, the safety rope 13 can be temporarily erected between the two vertical rods 5 after being respectively passed through and locked by the working shafts 1001 of the corresponding-side electric telescopic rods 10 through the two suspension rings 12.

[0028] Specifically, after the two ends of the working shaft 1001 are temporarily limited in the working limit holes 17 on the upper and lower side walls of the groove 9, the suspension rings worn on the working shaft 1001 are temporarily limited, thereby completing the erection of the safety rope 13.

[0029] Specifically, the rope tightener A2 and the rope tightener B3 have the same specifications, which is more conducive to the mutual cooperation and use between the two sets of rope tighteners.

[0030] Specifically, a fixing block 18 is provided on one side of the vertical rod 5 on the fastening block 1 for strengthening the connection strength of the vertical rod 5. The vertical rod 5 is threadedly connected to the fastening block 1. Anti-loosening nuts 4 are provided at both the upper and lower ends of the vertical rod 5 on the fixing block 1. In this way, the top height position of the vertical rod 5 can be adjusted according to needs during actual use to adapt to different usage requirements. For example, for the circular sleeve lifting seat 20 in a slightly inclined vertical direction, the top of the vertical rod 5 can be appropriately raised to adapt to the appropriate hanging height of the safety belt for use.

[0031] Specifically, the fixing block 18 and the fastening block 1 are of an integral structure and their upper and lower end faces are flush, with high connection strength and convenient use.

[0032] Specifically, in the middle of the side of the fastening block 1 away from the vertical rod 5, there is an arc-shaped groove 14 in the direction parallel to the vertical rod 5, which is used to fit the arc-shaped side of the circular sleeve lifting seat 20. As shown in Figure 5 shown, the contact area of the two mutually matching arc-shaped surfaces is large, and the installation and fastening effect is better.

[0033] Specifically, in the middle of the side of the fastening block 1 away from the vertical rod 5, there is a U-shaped groove 15 in the direction perpendicular to the vertical rod 5, which is used to fit the rhombic side of the square channel steel 21. As shown in Figure 6 shown, the contact area of the two mutually matching U-shaped surfaces is large, and the installation and fastening effect is better.

[0034] Specifically, in order to facilitate the later maintenance and repair work of the electric telescopic rod 10, the top of the vertical rod 5 is detachably connected with a cover plate 11. There is a receiving groove 16 at the top of the vertical rod 5 that matches the placement of the electric telescopic rod 10. After the electric telescopic rod 10 is installed at the lower end of the cover plate 11, it is placed in the receiving groove 16. When needed, the electric telescopic rod 10 can be taken out by removing the cover plate 11.

[0035] Specifically, a toxic gas sensor 6, a sound and light alarm 8 and a controller 7 are provided on the vertical rod 5. A detachable rechargeable battery (not shown in the figure) is installed in the controller 7. The rechargeable battery is located inside the controller for convenient electrical connection. The controller 7 is electrically connected to the rechargeable battery, the toxic gas sensor 6, the sound and light alarm 8, and the electric telescopic rod 10 respectively; during use, under the control of the controller 7, the toxic gas sensor 6 is used to detect the gas in the on-site working environment. After detecting toxic gas, the electric telescopic rod 10 is triggered to release the safety rope 13, and at the same time, the sound and light alarm 8 is triggered, thus completing the alarm and emergency escape work.

[0036] Specifically, the groove 9 is arranged in a horn shape, just a micro-horn shape, which is convenient for the hanging ring 12 to slide out more smoothly.

[0037] Specifically, a lighting lamp 22 electrically connected to the controller 7 is provided on the vertical rod 5 to provide night lighting work and facilitate night use. The switch button of the lighting lamp 22 can be integrally arranged on the panel of the controller 7.

[0038] Specifically, the controller 7 is internally provided with a positioning module (not shown in the figure) and a wireless communication module (not shown in the figure), which are used to obtain the real-time working position information of the staff for convenient monitoring and rescue.

[0039] During specific implementation, a control button for the electric telescopic rod 10 can be set at the top of the vertical rod 5 to facilitate the suspension work of the safety rope 13 when the entire device is installed and used.

[0040] When the present invention is actually used, after installing two fixed brackets at a preset spacing and adapting and installing them at the working position through two sets of rope tighteners, adjust the working height of the vertical rod 5, then hang both ends of the safety rope 13 on the tops of the two fixed brackets, and then hang the hook of the full-body safety belt worn on the staff on the safety rope 13, and the staff can start working; during the work, the safety belt hook can slide left and right along the safety rope 13, facilitating the staff to complete the work within a large range; when working at night, the lighting lamp 22 can be turned on; during the work, the toxic gas sensor 6 detects the gas in the working environment in real time to ensure the safety of the staff's working environment.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that it is still possible to modify or equivalently replace the specific implementation manners of the present invention.
