[0002] With the increase of the service life of transmission towers and the influence of various climatic conditions and natural environments, the structure of transmission towers will suffer damage such as corrosion and deformation. In particular, the tower legs of transmission towers connect the tower body and the foundation. Due to environmental pollution, soil burial, and water accumulation in the protective cap, etc., the tower legs are severely corroded. Corrosion damage is the most common and serious form of tower leg damage. Severe corrosion will cause the angle steel of the tower legs to become thinner, seriously weakening the mechanical properties of the transmission tower. In the current situation of frequent extreme weather, it is extremely easy to cause the occurrence of transmission tower collapse accidents; therefore, it is necessary to reinforce the angle steel tower legs by welding, etc., to improve the bearing capacity of the transmission tower and ensure the safe and stable operation of the transmission line.

Detailed implementation manners

[0029] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0031] Embodiment 1:

[0032] As recorded in the background art, there are various types of transmission tower tower shapes, and the tower leg structures and operating spaces are different, making it difficult to install the mounting plate 100 on three angle steels distributed in a direct triangle, and the mounting plate 100 is interfered by the main limb angle steel during installation. As Figure 1As shown, taking the 7727 tower type as an example, the tower leg structure 400 includes a first angle steel 401, a second angle steel 402, and a third angle steel 403 that form a triangle, and a main limb angle steel 404 perpendicular to the plane where the triangle is located; among them, the first angle steel 401 and the second angle steel 402 are two right sides, and the third angle steel 403 is the hypotenuse; the angle steel structure of the triangle makes it difficult to install the mounting plate 100 on the first angle steel 401, the second angle steel 402, and the third angle steel 403, and the mounting plate 100 is interfered by the main limb angle steel 404 during installation.

[0033] In view of the above problems, as Figure 2 shown, this embodiment provides a welding equipment fixture for an adaptive transmission angle steel tower tower leg reinforcement scenario, including a mounting plate 100, a plurality of first clamping mechanisms 200 provided at one end of the mounting plate 100, and a plurality of second clamping mechanisms 300 provided at the other end of the mounting plate 100.

[0034] Optionally, as Figure 2 shown, the mounting plate 100 is set as a high-strength aluminum alloy plate 6061T6 with a size of 800mm×300mm×15mm, and the weight is only 3KG. The mounting plate 100 is light in weight, simple in structure, and convenient for loading and unloading.

[0035] As Figure 2 and Figure 3 shown, a plurality of first bolt holes 107 are provided at the middle position of the mounting plate 100 for installing welding equipment, such as welding robotic arms and other equipment. It should be noted that a metal plate with a connection hole or other structure can be welded on an existing welding robotic arm or other welding equipment, and the welding robotic arm or other welding equipment can be set on the mounting plate 100 by means of the first bolt holes 107, connection holes, bolts, etc.

[0036] The welding robotic arm or other welding equipment is fixed to the center position of the mounting plate 100 through the first bolt holes 107 opened at the center position of the mounting plate 100. The mounting plate 100 can be quickly clamped and fixed on the transmission tower by using the first clamping mechanism 200 and the second clamping mechanism 300. The center of gravity of the welding robotic arm or other welding equipment is at the center position of the mounting plate 100, which can ensure the stability of the center of gravity during the working process of the mounting plate 100 and prevent vibration caused by the swing of the welding robotic arm or other welding equipment.

[0037] The design of the mounting plate 100 makes full use of the installation of the crossbeam angle steel of the transmission tower to ensure stability and the self-bearing capacity of the tower leg angle steel, simplifies the installation process, reduces the weight of the welding robot, enables quick and simple installation, and is light in weight and convenient for moving and changing positions.

[0038] As Figure 4As shown, the mounting plate 100 can be set as a straight plate structure, which has a simple manufacturing process. However, during the installation process, it may be limited by the position of the main limb angle steel 404 of some tower legs, resulting in inability to install. Based on this, as Figure 5 shown, a notch 108 is opened on the mounting plate 100.

[0039] Specifically, as Figure 2 and Figure 5 shown, the notch 108 is located at the middle position of the mounting plate 100, near one end of the second clamping mechanism 300. The mounting plate 100 is set in a structural form with a notch 108 in the middle, which not only reduces the weight of the mounting plate 100 but also is not affected by the position of the main limb angle steel 404.

[0040] As Figure 2 shown, one end of the mounting plate 100 is provided with a first mounting position 101 and a second mounting position 102, and the other end is provided with a third mounting position 103 and a fourth mounting position 104; the first clamping mechanism 200 is respectively installed at the first mounting position 101 and the second mounting position 102; the second clamping mechanism 300 is respectively installed at the third mounting position 103 and the fourth mounting position 104.

[0041] As Figure 6 shown, optionally, the first clamping mechanism 200 includes a first connecting plate 201, a plurality of second bolt holes 202 opened on the first connecting plate 201, a first vertical plate 203 vertically arranged on the first connecting plate 201 by welding or integral molding, a first rotating rod 204 hinged on the first vertical plate 203, a first handle 205 and a first connecting rod 206 hinged on the first rotating rod 204, a first action rod 207 hinged to the first connecting rod 206 and the first vertical plate 203, and a first clamping assembly 208 arranged at one end of the first action rod 207 away from the first connecting rod 206.

[0042] Optionally, as Figure 2 and Figure 6As shown, the first connecting plate 201 and the first vertical plate 203 are metal plates; two first clamping mechanisms 200 are respectively arranged at the first installation position 101 and the second installation position 102 through a plurality of second bolt holes 202 and first connecting bolts 106. The first rotating rod 204 is a long rod, one end of which is connected to the first vertical plate 203 through a hinge, and the other end is connected to the first handle 205 and the first connecting rod 206 through a hinge. One end of the first connecting rod 206 far from the first rotating rod 204 is connected to the first action rod 207 through a hinge. The upper part of one end of the first action rod 207 is hinged to the first connecting rod 206, and the lower part is connected to the first vertical plate 203 through a hinge. The first vertical plate 203 for connecting one end of the first action rod 207 is higher than the end for connecting the first rotating rod 204, and an arc-shaped notch is provided at the position of the first vertical plate 203 where the first rotating rod 204 is located to meet the movement of the first rotating rod 204.

[0043] As Figure 2 shown, according to the force points of the mounting plate 100 and the structural characteristics of the transmission tower, four clamping mechanisms are installed at the four force points of the mounting plate 100. Using the principle of the dead point of the hinge lever, the mounting plate 100 is clamped and fixed on the transmission tower. The first clamping mechanism 200 and the second clamping mechanism 300 are small in volume, light in weight and large in clamping force, and can firmly fix the mounting plate 100. They are convenient to disassemble and install, and can reduce the on-site construction and installation time. Specifically, when pressing the end of the first handle 205 far from the first rotating rod 204, the first rotating rod 204 rotates relative to the first vertical plate 203, driving the first connecting rod 206 to rotate hingedly, thereby driving the first action rod 207 to rotate, so that the first clamping assembly 208 moves downward and presses against the third angle steel 403, achieving the purpose of clamping the third angle steel 403 between the mounting plate 100 and the first clamping assembly 208. When lifting the end of the first handle 205 far from the first rotating rod 204, the first rotating rod 204 rotates relative to the first vertical plate 203, driving the first connecting rod 206 to rotate hingedly, thereby driving the first action rod 207 to rotate, so that the first clamping assembly 208 moves upward and leaves the third angle steel 403, realizing unlocking.

[0044] As Figure 6 shown, the first clamping assembly 208 includes a first clamping plate 2081 and a second clamping plate 2082 located on the upper and lower sides of the first action rod 207, a first screw rod 2083 arranged on the first clamping plate 2081 and the second clamping plate 2082 through a second connecting bolt 2084, and a first chuck 2085 arranged on the first screw rod 2083.

[0045] Optionally, the first clamping plate 2081 and the second clamping plate 2082 are metal plates provided with through holes. The first screw rod 2083 passes through the through holes on the first clamping plate 2081 and the second clamping plate 2082, and the first clamping plate 2081 and the second clamping plate 2082 are clamped on the first actuating rod 207 by second connecting bolts 2084 arranged at the upper and lower ends. The shortest distance between the first chuck 2085 and the angle steel can be adjusted by adjusting the elongation of the first screw rod 2083, thereby improving flexibility. The first chuck 2085 can be set as a structure such as a metal plate.

[0046] Optionally, as Figure 2 and Figure 7 shown, the second connecting plate 301 and the second vertical plate 303 are metal plates; two second clamping mechanisms 300 are respectively arranged at the third installation position 103 and the fourth installation position 104 through a plurality of third bolt holes 302 and first connecting bolts 106. The second rotating rod 304 is a long rod, one end of which is connected to the second vertical plate 303 through a hinge, and the other end is connected to the second handle 305 and the second connecting rod 306 through a hinge. One end of the second connecting rod 306 far from the second rotating rod 304 is connected to the second actuating rod 307 through a hinge. The upper part of one end of the second actuating rod 307 is hinged to the second connecting rod 306, and the lower part is connected to the second vertical plate 303 through a hinge. The second vertical plate 303 for connecting one end of the second actuating rod 307 is higher than the end for connecting the second rotating rod 304, and an arc-shaped notch is provided at the position of the second vertical plate 303 where the second rotating rod 304 is located to meet the movement of the second rotating rod 304.

[0047] Specifically, when pressing down one end of the second handle 305 far from the second rotating rod 304, the second rotating rod 304 rotates relative to the second vertical plate 303, driving the second connecting rod 306 to rotate hingedly, thereby driving the second actuating rod 307 to rotate, so that the second clamping assembly 308 moves downward and presses against the first angle steel 401 or the second angle steel 402, achieving the purpose of clamping the first angle steel 401 or the second angle steel 402 between the mounting plate 100 and the second clamping assembly 308. When lifting up one end of the second handle 305 far from the second rotating rod 304, the second rotating rod 304 rotates relative to the second vertical plate 303, driving the second connecting rod 306 to rotate hingedly, thereby driving the second actuating rod 307 to rotate, so that the second clamping assembly 308 moves upward and leaves the first angle steel 401 or the second angle steel 402, achieving unlocking.

[0048] As Figure 2As shown, optionally, bosses 105 are respectively provided on the third mounting position 103 and the fourth mounting position 104, and the second clamping mechanism 300 is arranged on the bosses 105 by means of the first connecting bolts 106 or other connection means. The bosses 105 can be arranged as structures such as metal platforms. By providing the bosses 105, a height difference is created between the second clamping mechanism 300 and the first clamping mechanism 200 to adapt to the situation where there is a height difference between the third angle steel 403 and the other two angle steels.

[0049] As Figure 7 shown, the second clamping assembly 308 includes a third clamping plate 3081 and a fourth clamping plate 3082 located on the upper and lower sides of the second operating rod 307, a second screw rod 3083 arranged on the third clamping plate 3081 and the fourth clamping plate 3082 by means of the third connecting bolts 3084, and a second chuck 3085 arranged on the second screw rod 3083.

[0050] Optionally, the third clamping plate 3081 and the fourth clamping plate 3082 are metal plates provided with through holes. The second screw rod 3083 passes through the through holes on the third clamping plate 3081 and the fourth clamping plate 3082, and the third clamping plate 3081 and the fourth clamping plate 3082 are clamped on the second operating rod 307 by the third connecting bolts 3084 provided at the upper and lower ends. The shortest distance between the second chuck 3085 and the angle steel can be adjusted by adjusting the elongation of the second screw rod 3083, thereby improving flexibility. The second chuck 3085 can be arranged as a flexible pressing head or a metal head.

[0051] As Figure 2 、 Figure 6 and Figure 7 shown, optionally, the direction of the first operating rod 207 in terms of length is perpendicular to the direction of the second operating rod 307 in terms of length; the directions of the two first operating rods 207 in terms of length are parallel, and the two second clamping assemblies 308 respectively face the outside of the mounting plate 100. Specifically, the first clamping mechanism 200 is used to clamp the third angle steel 403 as the hypotenuse, and the two second clamping mechanisms 300 are respectively used to clamp the first angle steel 401 and the second angle steel 402, and the mounting plate 100 can be flexibly and quickly fixed to the three angle steels.
