Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools for high-voltage line operation and maintenance, specifically indicating a fall arrestor for operation on high-voltage line towers. Background Technology

[0002] When working on high-voltage line gantry cranes, because workers sit on the gantry and there is no steel structure higher than their body, the safety belts cannot meet the "high-hanging, low-use" principle—that is, the suspension point of the safety belt should be higher than the working position to effectively cushion the impact in the event of a fall. The lack of safety-compliant suspension conditions leads to violations of regulations during on-site operations, greatly increasing the risk of falls from height and posing a serious threat to the personal safety of workers. Therefore, a clamp needs to be designed to work in conjunction with an insulating rod to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to overcome the technical defect that safety belts cannot be used at a high height and low height when working on high-voltage line gantry frames, and to provide a fall protection clamp for working on high-voltage line towers.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a fall arrestor for working on high-voltage line towers, comprising a gantry angle steel, an insulating rod, and a safety belt, and further comprising a fixing base, a fixing column, and an angle steel hook. The fixing column is a threaded rod structure with a limiting base plate fixed at its bottom and a clamping nut installed at its top. The fixing base has a through hole one, and the angle steel hook has a through hole two. The fixing column passes through the through hole one and the through hole two in sequence. One end of the fixing base is bent to form a fixing hook. The gantry angle steel is limited within the fixing hook and the angle steel hook. Both the fixing base and the angle steel hook have threaded holes. The insulating rod base has a screw post, which can be installed in any of the threaded holes. The top of the insulating rod has a hanging hole, and the safety belt is hung in the hanging hole.

[0005] Furthermore, the angle steel hook and the fixing hook are both set as inclined surfaces on the side of the angle steel of the gantry frame.

[0006] Furthermore, both the top surface of the limiting base plate and the bottom surface of the fixing base are provided with teeth, and the teeth on the two cooperate with each other.

[0007] Furthermore, the through hole is an elongated structure, and its direction is perpendicular to the length direction of the tooth.

[0008] Furthermore, the width of the limiting base plate in the front-to-back direction is the same as the width of the fixing base in the front-to-back direction.

[0009] Furthermore, the clamping nut is a wing nut.

[0010] The beneficial effects of this utility model are:

[0011] 1. In this utility model, the angle steel of the gantry frame is limited between the base of the fixing device and the angle steel hook. The fixing device base and the angle steel hook are limited and fixed by the limiting base plate and the clamping nut on the fixing device column, thereby ensuring that the clamp is firmly fixed on the angle steel of the gantry frame and preventing the clamp from loosening or falling off.

[0012] 2. The teeth on the top surface of the limiting base plate and the bottom surface of the fixing base cooperate with each other to prevent relative sliding and further ensure the stability of the fixation.

[0013] 3. Create a safe condition for high-hanging and low-use of safety belts by using insulating rods. The bottom of the insulating rod is firmly fixed to the base of the fixing device or the angle iron hook with screw posts, and the top can be used to hang the safety belt, so as to avoid the safety belt violating the principle of high-hanging and low-use during operation.

[0014] 4. The clamping nut adopts a wing nut, which makes it easy for the operator to turn the clamping nut to achieve a convenient and firm tightening effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] Embodiments of this utility model: such as Figure 1-5 As shown, a fall arrestor for working on a high-voltage transmission tower includes a gantry angle steel 1, an insulating rod 2, and a safety belt. It also includes a fixing base 3, a fixing column 4, and an angle steel hook 5. The fixing column 4 is a threaded rod structure with a limiting base plate 6 fixed at its bottom and a clamping nut 7 installed at its top. The fixing base 3 has a through hole 8, and the angle steel hook 5 has a through hole 9. The fixing column 4 passes through the through hole 8 and the through hole 9 in sequence. One end of the fixing base 3 is bent to form a fixing hook 10, which limits the gantry angle steel 1 within the fixing hook 10 and the angle steel hook 5. Both the fixing base 3 and the angle steel hook 5 have threaded holes 11. The base of the insulating rod 2 has a screw post 12, which can be installed in any of the threaded holes 11. The top of the insulating rod 2 has a hanging hole 14, in which the safety belt is hung.

[0023] It is worth noting that, due to the different setting angles of the angle steel 1 of the gantry frame, threaded holes 11 are set on both the fixing base 3 and the angle steel hook 5. When installing the insulating rod 2, a threaded hole 11 that allows the insulating rod 2 to be installed vertically is selected for installation, thereby providing the conditions for the safety belt to be hung high and used low.

[0024] like Figure 2 As shown, the angle steel hook 5 and the fixed hook 10 are both set as inclined surfaces on the side of the angle steel 1 of the gantry frame.

[0025] The above structure allows this clamp to be used with angle steel of different thicknesses.

[0026] like Figure 3 , 4 As shown, the top surface of the limiting base plate 6 and the bottom surface of the fixing base 3 are both provided with teeth 13, and the teeth 13 on the two cooperate with each other.

[0027] The above structure prevents relative sliding between the limiting base plate 6 and the fixing base 3, ensuring that the clamp is stably fixed on the gantry angle steel 1 and preventing loosening.

[0028] like Figure 5 As shown, the through hole 8 is a long strip structure, and its direction is perpendicular to the length direction of the tooth 13.

[0029] The above structure facilitates the installation of the fixing base 3 on the angle steel 1 of the gantry frame.

[0030] like Figure 1-5 As shown, the clamping nut 7 is a wing nut.

[0031] The above structure allows operators to easily rotate the clamping nut, achieving a convenient and secure tightening effect.

[0032] The width of the limiting base plate 6 in the front-to-back direction is the same as the width of the fixing base 3 in the front-to-back direction.

[0033] In specific use of this embodiment, when working on the high-voltage line gantry, loosen the clamping nut 7 so that the gantry angle steel 1 can pass between the fixed hook 10 and the angle steel hook 5, so that the gantry angle steel 1 is limited between the fixed hook 10 and the angle steel hook 5; rotate the clamping nut 7 to bring the angle steel hook 5 and the fixing base 3 closer together to clamp and fix the gantry angle steel 1; then hang the safety belt hook on the top of the insulating rod 2, select the threaded hole 11 that allows the insulating rod 2 to be installed vertically, and install the screw post 12 on the base of the insulating rod 2 into the threaded hole 11 to achieve high hanging and low use of the safety belt.
