Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a universal mounting fastener for signs applicable to power transmission towers. Background Technology

[0002] With the widespread application of drone inspection technology in the operation and maintenance of overhead transmission lines, the deficiencies in the existing installation firmware of power tower markers have severely hampered the standardization of inspection operations, mainly manifested in the following prominent issues:

[0003] The lack of standardization leads to insufficient universality: the industry lacks unified design specifications, and the firmware of various manufacturers has different structural forms and incompatible interfaces, resulting in a cross-regional line firmware interchangeability rate of less than 30%. The lack of installation process standards and the differences in construction methods have led to a significant increase in the average installation time of a single iron tower by 45%. The installation location is highly random, and the drone sign deviates from the baseline positioning line by more than 20cm.

[0004] The contradiction between installation efficiency and safety is prominent: traditional bolt fastening requires carrying a variety of tools to climb to heights, and the average installation time for a single piece is up to 25 minutes. The strap fixing method has a 30% aging and breakage rate. In the statistics of high-altitude fall accidents, 23% are directly related to the slippage of fastener installation tools and the loosening of fasteners.

[0005] There are systemic defects in structural reliability: the annual loosening rate of bolted connections reaches 18% under wind vibration environment, the UV resistance of plastic die castings is insufficient, the surface cracking rate reaches 100% after 2 years, and the average fatigue fracture cycle of welded angle steel is less than 5 years.

[0006] High life-cycle costs: Non-standard parts increase mold development costs by 200%-300%, sign replacement during line relocation requires complete disassembly, material loss rate reaches 85%, and maintenance costs account for more than 3.2 times the initial installation cost;

[0007] The existing firmware is not compatible with the installation of signs of various sizes and models. The firmware and signs lack modular design, and upgrading the function requires replacing the entire system.

[0008] To address these issues, a universal mounting firmware for signs on power transmission towers is proposed. Utility Model Content

[0009] The purpose of this utility model is to provide a universal mounting firmware for signs on power transmission towers, so as to solve the problems mentioned in the background art.

A barbed angle steel fixing bolt is provided on the rear side of the bracket mounting body and inside the positioning support block. A first locking nut is threaded to the outer wall of the barbed angle steel fixing bolt inside the bracket mounting body.

[0012] An angle steel clamping wedge is provided on the rear side of the bracket mounting body, and a symmetrical limiting ratchet is provided on the front side of the angle steel clamping wedge. The front end of the limiting ratchet is engaged with the adjusting groove. A hexagonal bolt is provided through the side wall of the angle steel clamping wedge, and a second locking nut is threadedly connected to the outside of the hexagonal bolt inside the bracket mounting body.

[0013] The angle steel is fixed together by the angle steel clamping wedge and the barbed angle steel fixing bolt.

[0014] Preferably, the upper and lower ends of the side wall of the bracket mounting body are provided with symmetrical mounting process holes, and each of the two mounting process holes is fixed with a locking screw.

[0015] Preferably, each of the two fixed brackets has a sliding slot on its front side, and the upper and lower ends of the sign are located inside the sliding slot.

[0016] Preferably, the upper side of the barbed angle steel fixing bolt contacts the upper end of the inner wall of the positioning support block.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Example:

[0033] Please see Figures 1-6 This utility model provides a technical solution:

[0034] A universal mounting fastener for signs on power transmission towers includes a bracket mounting body 1, with symmetrical aircraft wing tabs 2 fixed on the left and right sides of the bracket mounting body 1, and a fixing bracket 3 fixed to the front end of each of the two sets of aircraft wing tabs 2.

[0035] Fix the bracket mounting body 1 to the angle steel 12. Position the support block 5 against one side of the angle steel 12. Insert the barbed angle steel fixing bolt 6 into the bracket mounting body 1, hooking one end of the barbed angle steel fixing bolt 6 onto the angle steel 12. Slightly tighten the first locking nut 7 at the other end to prevent it from falling off. Then, install the angle steel clamping wedge 8, adjusting it to a suitable position so that the angle steel clamping wedge 8 is just locked in the adjustment hole. Finally, tighten the hexagonal bolt 10 to complete the fixed installation of the bracket mounting body 1 on the angle steel 12.

[0036] A sign 4 is clamped and fixed between two fixed brackets 3. A first strip-shaped opening is opened on the front side of the bracket mounting body 1, and a second strip-shaped opening is opened on the rear side of the bracket mounting body 1. Adjustment grooves are evenly arranged at the left and right ends of the second strip-shaped opening. A positioning support block 5 is fixed at the upper end of the second strip-shaped opening. A barbed angle steel fixing bolt 6 is set on the rear side of the bracket mounting body 1 and inside the positioning support block 5. A first locking nut 7 is threadedly connected to the outer wall of the barbed angle steel fixing bolt 6 inside the bracket mounting body 1.

[0037] An angle steel clamping wedge 8 is provided on the rear side of the bracket mounting body 1. A symmetrical limiting ratchet 9 is provided on the front side of the angle steel clamping wedge 8. The front end of the limiting ratchet 9 is engaged with the adjustment groove. A hexagonal bolt 10 is provided through the side wall of the angle steel clamping wedge 8. The outer side of the hexagonal bolt 10 is connected to the second locking nut 11 by a thread inside the bracket mounting body 1.

[0038] When the barbed angle steel fixing bolt 6 and the hexagonal bolt 10 are inserted into the bracket mounting body 1, the first locking nut 7 and the second locking nut 11 are located at one end in the groove of the bracket mounting body 1. The first locking nut 7 and the second locking nut 11 are blocked by the marking plate 4, which restricts their axial freedom. At the same time, one end of the barbed angle steel fixing bolt 6 is connected to the angle steel 12, which restricts its rotational freedom. Similarly, one end of the hexagonal bolt 10 presses against the angle steel 12, and the locking pin 13 on the angle steel pressing wedge block 8 locks and restricts its rotational freedom. This design can prevent the nuts from loosening and falling, and also facilitates the installation and removal of bolts.

[0039] Angle steel 12 is fixed together by the angle steel clamping wedge block 8 and the barbed angle steel fixing bolt 6.

[0040] The upper and lower ends of the side wall of the bracket mounting body 1 are provided with symmetrical installation process holes, and the inside of the two installation process holes is fixed with a pressure locking screw.

[0041] Both fixed brackets 3 have sliding slots on their front sides, and the upper and lower ends of the sign 4 are located inside the sliding slots.

[0042] The upper side of the barbed angle steel fixing bolt 6 contacts the upper end of the inner wall of the positioning support block 5.

[0043] A locking pin 13 is fixed to the rear side of the angle steel clamping wedge block 8, and the upper side of the locking pin 13 is engaged with the lower side of the hexagonal bolt 10.

[0044] The aircraft wing support 2 is connected and fixed to the fixed bracket 3 by rivets.

[0045] (1) The structure adopts an "H"-shaped design, the core of which mainly consists of the bracket mounting body 1, two aircraft wing tabs 2, and two fixed brackets 3. The aircraft wing tabs 2 are embedded and fixed to the bracket mounting body 1, ensuring the horizontality and integrity of the installation without moving left or right or up or down. The fixed slots are designed to resemble the shape of a human hand gripping, which can more efficiently and firmly hold the sign 4. Combining them into an "H"-shaped structure further optimizes the volume and weight, and has significant advantages such as simple installation.

[0046] (2) Adaptability and anti-loosening mechanism: The device is equipped with adjustment holes and angle steel clamping wedges 8, which can greatly improve the device installation and prevent loosening caused by swinging and other factors when the device is installed at high altitude. In addition, it also plays a role in adjusting the size and can better adapt to angle steel 12 of different specifications.

[0047] Working principle:

[0048] Select a suitable installation location on the tower, fix the main body 1 of the mounting bracket to the angle steel 12, place the positioning support block 5 against one side of the angle steel 12, insert the barbed angle steel fixing bolt 6 into the mounting body 1 of the bracket and hook one end of the barb onto the angle steel 12, and thread the first locking nut 7 at the other end to prevent it from falling off.

[0049] Then, install the angle steel clamping wedge 8, adjust the position according to the size of the angle steel 12 to make the angle steel clamping wedge 8 fit into the adjustment hole of the bracket mounting body 1, and finally tighten all the hexagonal bolts 10 and the second locking nut 11 to complete the fixed installation of the bracket mounting body 1 and the angle steel 12.

[0050] After the bracket mounting body 1 is fixed, insert the sign 4 into the fixed bracket 3. After installation, tighten the locking screws through the mounting process holes on the fixed bracket 3 to firmly fix the sign 4 in the slot, preventing it from coming out or falling off.

[0051] Finally, shake the sign 4 and the fixed bracket 3 to check whether they are installed firmly and to avoid shaking.
