Description

Technical Field

[0001] This application relates to the technical field of transmission line towers, and in particular to a fall arrestor for 35kV towers. Background Technology

[0002] With the acceleration of urbanization, numerous power facilities have been built across my country, bringing great convenience to people's daily lives. However, many shortcomings and difficulties still exist in the operation and maintenance of power lines. For example, climbing power towers (iron towers) is a fundamental and essential task in the operation and maintenance of transmission lines. Tower foot spikes are climbing aids used by operators to ascend and descend the towers.

[0003] Existing tower footings consist of a long screw, adjusting nut, washer, and fastening nut. These footings are typically installed on one of the main members of the tower. The long screw is fixed to the tower component by the adjusting nut and fastening nut. Although installation is convenient and quick, there is no safety guarantee for operators when climbing the tower with their feet on the long screw. They are prone to slipping or losing their footing if they are not careful. There have been many accidents in the power system where operators have fallen due to safety belts coming loose or their feet slipping during tower climbing. This greatly increases the probability of safety accidents during construction and poses a huge hidden danger to the operation of power transmission lines. Utility Model Content

[0004] In order to reduce the probability of operation and maintenance risks and reduce safety hazards, this application provides a fall protection foot spike for 35kV towers.

[0005] The anti-fall spike for 35kV transmission towers provided in this application adopts the following technical solution:

[0006] A fall arrestor for a 35kV transmission tower includes a fixing plate, a base plate, an arc-shaped panel, and a hook. The fixing plate is attached to one side of the tower's angle steel and fixedly connected to it. The base plate is perpendicular to and fixedly connected to the fixing plate. The arc-shaped panel is located above the base plate, with one end fixedly connected to the fixing plate and the other end fixedly connected to the end of the base plate away from the fixing plate. The hook is fixedly connected to the fixing plate. A U-shaped handle is horizontally provided on one side of the base plate, with one end fixedly connected to the fixing plate and the base plate, and the other end fixedly connected to the end of the base plate away from the fixing plate.

[0007] By adopting the above technical solution, the base plate is horizontally set and suspended, with an arc-shaped panel placed above it, forming an arched space for operators to pass through. The base plate is fixedly connected to a fixed plate, which is then fixed to the angle steel of the tower. When an operator's foot passes through the arched space, it steps on the base plate, and the instep of the foot contacts the inside of the arc-shaped panel, securing the foot in the arched space and preventing slippage. The handle design allows operators to use it for leverage to climb upwards, and the hook design allows for the attachment of safety belts. This design improves operational safety, facilitates maintenance and repair, and prevents operators from losing their balance due to slipping or safety belt detachment, thus avoiding falls and personal injury accidents. It significantly reduces the probability of safety accidents during construction and minimizes safety hazards.

[0008] Optionally, the arc-shaped panel includes a first arc-shaped plate and a second arc-shaped plate. Both the first arc-shaped plate and the second arc-shaped plate have a curved "H"-shaped structure. One end of the first arc-shaped plate is fixedly connected to a fixed plate, and the other end is fixedly connected to one end of the second arc-shaped plate. The other end of the second arc-shaped plate is fixedly connected to a base plate. The first arc-shaped plate and the second arc-shaped plate form an arc-shaped panel with hollowed-out ends and middle.

[0009] By adopting the above technical solution, the first arc-shaped plate and the second arc-shaped plate form an arc-shaped panel with hollowed-out ends and middle, which not only maintains the arched structure of the arc-shaped panel, but also saves raw materials, reduces the weight of the foot nails themselves, and facilitates replacement and maintenance, thereby reducing operation and maintenance costs.

[0010] Optionally, a spring is also provided between the first arc-shaped plate and the second arc-shaped plate, with one end of the spring fixedly connected to the first arc-shaped plate and the other end fixedly connected to the second arc-shaped plate.

[0011] By adopting the above technical solution, a spring is set between the first arc-shaped plate and the second arc-shaped plate. When the elastic force of the spring is within a certain range, it can not only make the first arc-shaped plate and the second arc-shaped plate have a certain degree of fastening, but also slightly increase the distance between the first arc-shaped plate and the second arc-shaped plate under the action of elasticity, so as to have a certain buffering effect, so that the operator's feet are not squeezed too tightly, thus enhancing comfort.

[0012] Optionally, the hook includes an extension and a vortex hook. The extension is perpendicular to the fixing plate and is fixedly connected to the fixing plate at one end and to the vortex hook at the other end. The vortex hook vortexes inward from one end opening.

[0013] By adopting the above technical solution, one end of the extension is fixedly connected to the fixed plate, and the other end extends out of the fixed plate, which makes it convenient for operators to hook the safety belt into the vortex hook during the climbing process. The design of the vortex hook allows the safety belt to be hung inward from the opening of the vortex hook, preventing the safety belt from falling off the vortex hook when the operator is in a slack state during the climbing process, and further enhancing the stability of the safety belt.

[0014] Optionally, an anti-detachment ball is provided at the opening of the vortex hook, the anti-detachment ball being integrally formed with the vortex hook, and the diameter of the anti-detachment ball being larger than the cross-section of the vortex hook.

[0015] By adopting the above technical solution, an anti-detachment ball is set at the opening of the vortex hook, which allows the safety belt to be easily hooked into the vortex hook without easily falling off, thus reducing the occurrence of safety belt detachment accidents during operation.

[0016] Optionally, fixing holes are provided at all four corners of the fixing plate, and bolt holes are provided on the tower angle steel accordingly. Fixing bolts are inserted into the fixing holes, and the fixing bolts are tightened by fixing nuts after passing through the fixing holes and bolt holes in sequence.

[0017] By adopting the above technical solution, fixing holes are opened at the four corners of the fixing plate, and fixing bolts are used to fix the fixing plate to the angle steel of the tower. Compared with the fixing of a single long screw, the fixing of four fixing screws is more secure, safer, and not easily disassembled.

[0018] Optionally, the fixing nut has a bowl-shaped structure, and the fixing nut is threadedly connected to the fixing bolt and abuts against the inside of the tower angle steel.

[0019] By adopting the above technical solution, the fixing nut is designed as a bowl-shaped structure, which can not only be fixedly connected with the fixing bolt and tighten the fixing bolt, but also be fastened to the surface of the tower angle steel to prevent wind and rain from corroding the fixing bolt, reduce the damage to the threads of the fixing bolt and fixing nut that would cause the connection between the two to become weak, and extend the service life of the fixing bolt and fixing nut.

[0020] Optionally, the inner surface of the base plate is provided with several grooves.

[0021] By adopting the above technical solution, grooves are opened on the inner side of the base plate, making the surface of the base plate uneven. This increases the friction between the operator's shoe sole and the base plate, making it less likely to slip and further ensuring the safety of the operator.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting the base plate horizontally and suspending it in the air, and placing the curved panel above the base plate to form an arched space, when the operator's feet pass through the arched space, their feet touch the base plate, and the instep of their feet contacts the inside of the curved panel, securing their feet in the arched space and preventing slippage. The handles allow operators to use them for leverage to climb upwards, and the hooks allow for the attachment of safety belts. This design prevents operators from losing their balance due to slipping or the safety belt coming loose, thus avoiding falls and personal injury accidents. It significantly reduces the probability of safety accidents during construction and minimizes safety hazards.

[0024] 2. By setting a spring between the first arc-shaped plate and the second arc-shaped plate, when the spring force is within a certain range, the first arc-shaped plate and the second arc-shaped plate can have a certain degree of tightness, and under the action of elasticity, the distance between the first arc-shaped plate and the second arc-shaped plate can be slightly increased, which has a certain buffering effect, so that the operator's feet are not squeezed too tightly, thus enhancing comfort.

[0025] 3. The design of the vortex hook allows the safety belt to be suspended by rotating inward from the opening of the vortex hook, preventing the safety belt from falling off the vortex hook when the operator is in a slack state during climbing, thus further enhancing the stability of the safety belt.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] Tower anchors are mostly installed in the diagonal area of ​​the tower body, starting from about 1.5 meters above the top plane of the foundation and ending at 0.5 meters above the top of the tower. They are installed alternately on both sides of a main angle steel member, with a spacing of about 0.45 meters.

[0031] This application discloses a fall arrestor for 35kV transmission towers. (Refer to...) Figure 1A fall arrestor for 35kV transmission towers includes a fixing plate 1, a base plate 2, an arc-shaped panel 3, and a hook 4. The fixing plate 1 serves as the foundation supporting the entire fall arrestor. The fixing plate 1 is attached to one side of the tower angle steel 9 and fixedly connected to the tower angle steel 9 by bolt assemblies. The base plate 2 is perpendicular to the fixing plate 1 and located below the vertical fixing plate 1. The base plate 2 and the fixing plate 1 are integrally formed. Several grooves 21 are formed on the upper inner surface of the base plate 2. The grooves 21 make the upper surface of the base plate 2 uneven, thereby increasing the friction of the base plate 2. The arc-shaped panel 3 is located directly above the base plate 2, and one end of the arc-shaped panel 3 is integrally formed with the fixing plate 1 and the base plate 2, while the other end is integrally formed with the end of the base plate 2 away from the fixing plate 1. The hook 4 is located on the upper end of the fixing plate 1, also above the arc-shaped panel 3, and the hook 4 is integrally formed with the fixing plate 1. When the foot nail is fixed to the angle steel 9 of the tower, a "U" shaped handle 5 is horizontally set on the side of the base plate 2 facing the operator. The "U" shaped handle 5 is flush with the base plate 2, and the opening of the "U" shaped handle 5 faces the base plate 2. One end of the "U" shaped handle 5 is integrally formed with the fixing plate 1 and the base plate 2, and the other end is integrally formed with the end of the base plate 2 away from the fixing plate 1.

[0032] The arc-shaped panel 3 includes a first arc-shaped plate 31 and a second arc-shaped plate 32. Both the first arc-shaped plate 31 and the second arc-shaped plate 32 are curved "H"-shaped structures. The two curved first arc-shaped plates 31 and the second arc-shaped plate 32 are spliced ​​together to form an arch structure. One end of the first arc-shaped plate 31 is integrally formed with the fixing plate 1 and the base plate 2, and the other end is fixedly connected to one end of the second arc-shaped plate 32. The other end of the second arc-shaped plate 32 is integrally formed with the end of the base plate 2 away from the fixing plate 1. The first arc-shaped plate 31 and the second arc-shaped plate 32 form an arc-shaped panel 3 with hollow ends and a hollow middle. The hollow structure design can not only reduce the weight of the entire foot nail, but also save raw materials.

[0033] To provide a buffer between the first arc-shaped plate 31 and the second arc-shaped plate 32, a spring 6 is also provided between the first arc-shaped plate 31 and the second arc-shaped plate 32. One end of the spring 6 is embedded in the inner side of the first arc-shaped plate 31 and welded to the first arc-shaped plate 31, and the other end is embedded in the inner side of the second arc-shaped plate 32 and welded to the second arc-shaped plate 32.

[0034] To enhance the stability of the fixing plate 1, fixing holes 11 are provided at all four corners of the fixing plate 1, and bolt holes 91 are provided on the tower angle steel 9 accordingly. Fixing bolts 7 are inserted into the fixing holes 11. After the fixing bolts 7 pass through the fixing holes 11 and bolt holes 91 in sequence, they are tightened by fixing nuts 8, thereby fixing the fixing plate 1 to the tower angle steel 9.

[0035] To reduce the risk of the fixing nut 8 loosening or falling off due to wind and rain erosion, the fixing nut 8 has a bowl-shaped structure. The fixing nut 8 is threadedly connected to the fixing bolt 7 and is pressed against the inside of the tower angle steel 9. This can effectively reduce the entry of rainwater and wind sand into the threaded connection between the fixing nut 8 and the fixing bolt 7, thereby reducing damage to the threaded connection.

[0036] Reference Figure 1 and Figure 2 The hook 4 includes an extension 41 and a spiral hook 42. The extension 41 is perpendicular to the fixing plate 1 and is integrally formed with the fixing plate 1 at one end, while the other end is integrally formed with the outer ring of the spiral hook 42. The spiral hook 42 is located above the first arc-shaped plate 31. The spiral hook 42 spirals inward from one end opening at least two times, allowing the safety belt to be hooked in from the opening and then suspended by spiraling inward along the spiral direction. When climbing up or down, the operator can hook the safety belt only on the outer ring for easy removal; when stopping to work, the operator can spiral the safety belt inward and hook it on the inner ring, allowing them to concentrate on the work without worrying about the safety belt falling off.

[0037] An anti-detachment ball 43 is provided at the opening of the vortex hook 42. The anti-detachment ball 43 is integrally formed with the vortex hook 42. The diameter of the anti-detachment ball 43 is larger than the cross-section of the vortex hook 42, so that the safety belt will not easily fall off from the opening.

[0038] All integral moldings in this application refer to welded or pre-molded structures at the time of shipment.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
