Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and in particular relates to a welding device for the steel structure of a high-speed railway platform canopy. Background Technology

[0002] Steel structures for high-speed railway platform canopies are common shelters on high-speed railway platforms. They are mainly composed of steel structural frames and covering materials. As an important part of high-speed railway stations, high-speed railway platform canopies need to withstand the effects of wind pressure, rain, snow and other natural forces.

[0003] Welding, as a reliable connection method, can firmly connect various parts of a steel structure together to form a whole structure, thereby improving its stability and safety. Through welding, it can be ensured that the steel structure is not easily deformed or damaged when subjected to various external forces, providing passengers with a safe and comfortable waiting environment. AC welding machines can be used for welding operations in the steel structure welding process of high-speed rail platform canopies. Since the bottom of the AC welding machine is often connected to multiple rollers for movement, it is easy to move when the AC welding machine is hit. Moreover, due to the close contact distance with the ground, if the ground environment is damp, it can easily reduce the insulation capacity of the welding machine and welding equipment, increasing the risk of electric shock. The problems with the above technology are: it cannot increase the contact height between the AC welding machine and the ground, and the anti-slip ability of the AC welding machine is not good enough. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a welding device for the steel structure of a high-speed railway platform canopy that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a welding device for the steel structure of a high-speed railway platform canopy, comprising a welding device and a support assembly. The welding device includes a control end, a body, and a shell. The control end is installed on the front side of the body. The surface of the body is fixedly connected to the interior of the shell by bolts. The support assembly is located at the bottom of the body. The support assembly includes a support plate, multiple columns, multiple control blocks, a tie rod, and a connecting column. The bottoms of the multiple columns are fixedly connected to the front and rear sides of the top left and right sides of the support plate, respectively. The interiors of the multiple control blocks are slidably connected to the surfaces of the multiple columns, and the opposite ends of the multiple control blocks are fixedly connected to the front and rear sides of the left and right sides of the shell, respectively. The bottoms of the tie rods are fixedly connected to the left and right sides of the top of the support plate, respectively. The surface of the connecting column is slidably connected to the center of the interior of the tie rod, and the bottom of the connecting column is fixedly connected to the top of the shell. A positioning assembly and a moving assembly are provided at the center of the top of the tie rod.

[0006] The welding device is used for welding the steel structure of the high-speed railway platform canopy.

[0007] The support assembly is used to increase the height between the welding device and the ground.

[0008] To ensure the connection and fixation of the connecting column and the tie rod, preferably, the positioning assembly includes two positioning blocks, two return springs, two upright plates, and two inclined plates. The rear sides of the two positioning blocks are fixedly connected to the front sides of the two inclined plates, the opposite ends of the two return springs are fixedly connected to the opposite sides of the two positioning blocks, and the opposite sides of the two return springs are fixedly connected to the opposite ends of the two upright plates. The bottom of each of the two upright plates is fixedly connected to the top of the tie rod. Through the positioning assembly, the two return springs both serve to fix and rebound, allowing the two positioning blocks and the two inclined plates to rebound back to their original positions after movement. This ensures that when the two positioning blocks are inserted into the two connecting columns, the connecting columns and the tie rod are fixed.

[0009] To allow the pull rod to move, preferably, the moving assembly includes a fixed plate, a moving rod, a moving block, two spring springs, two protrusions, and two movable columns.

The interior of the two movable columns is movably connected to the front side of the top of the two protrusions. The surfaces of the two movable columns are respectively in contact with the surfaces of the two inclined plates. Through the moving assembly, the two positioning blocks can be moved out of the interior of the connecting columns. The two spring springs both serve to fix and rebound, so that the moving rod, moving block, two protrusions, and two movable columns automatically rebound to their original positions after moving.

[0010] To ensure the proper functioning of the two inclined plates and two positioning blocks, preferably, two limiting posts are fixedly connected to opposite sides of each of the two positioning blocks. The surfaces of the multiple limiting posts are slidably connected to the interior of the two upright plates.

[0022] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown in the figure, this utility model provides a welding device for a steel structure of a high-speed railway platform canopy, including a welding device 1 and a support assembly 2. The welding device 1 includes a control end 101, a body 102, and a shell 103. The control end 101 is installed on the front side of the body 102. The surface of the body 102 is fixedly connected to the interior of the shell 103 by bolts. The support assembly 2 is disposed at the bottom of the body 102. The support assembly 2 includes a support plate 201, multiple columns 202, multiple control blocks 203, a tie rod 204, and a connecting column 205. The bottoms of the multiple columns 202 are fixedly connected to the front and rear sides of the top left and right sides of the support plate 201, respectively. The interiors of the multiple control blocks 203 are slidably connected to the surfaces of the multiple columns 202, respectively. The opposite ends are fixedly connected to the front and rear sides of the left and right sides of the outer shell 103, respectively. The bottom of the pull rod 204 is fixedly connected to the left and right sides of the top of the support plate 201, respectively. The surface of the connecting column 205 is slidably connected to the center of the inside of the pull rod 204. The bottom of the connecting column 205 is fixedly connected to the top of the outer shell 103. A positioning component 3 and a moving component 4 are provided at the center of the top of the pull rod 204. The welding device 1 is used for welding the steel structure of the high-speed railway platform canopy. The support component 2 is used to raise the height between the welding device 1 and the ground. In order to connect and fix the connecting column 205 and the pull rod 204, the positioning component 3 includes two positioning blocks 301, two return springs 302, two upright plates 303 and two inclined plates 304. The two positioning blocks 301 The rear sides of the two inclined plates 304 are fixedly connected to the front sides of the two return springs 302, respectively. The opposite ends of the two return springs 302 are fixedly connected to the opposite sides of the two positioning blocks 301, respectively. The opposite sides of the two return springs 302 are fixedly connected to the opposite ends of the two vertical plates 303, respectively. The bottom of the two vertical plates 303 is fixedly connected to the top of the pull rod 204. Through the positioning assembly 3, the two return springs 302 play a fixing and rebounding role, so that the two positioning blocks 301 and the two inclined plates 304 can rebound to their original positions after moving. Thus, when the two positioning blocks 301 are inserted into the two connecting columns 205, the connecting columns 205 are fixed to the pull rod 204. In order to allow the pull rod 204 to move, the moving assembly 4 includes a fixed plate 401, a moving rod 402, and a moving block. 403, two spring springs 404, two protrusions 405, and two movable columns 406; the bottom of the fixed plate 401 is fixedly connected to the rear side of the top of the pull rod 204; the surface of the movable rod 402 is slidably connected to the interior of the fixed plate 401; the front side of the movable rod 402 is fixedly connected to the rear side of the movable block 403; the front sides of the two spring springs 404 are respectively fixedly connected to the left and right sides of the rear of the movable block 403; the rear sides of both spring springs 404 are fixedly connected to the front side of the fixed plate 401; the rear sides of both protrusions 405 are fixedly connected to the front side of the movable block 403; the interior of the two movable columns 406 is movably connected to the front side of the top of the two protrusions 405; the surfaces of the two movable columns 406 are respectively in contact with the surfaces of the two inclined plates 304.By moving component 4, the two positioning blocks 301 can be moved out of the interior of the connecting column 205. Both springs 404 serve to fix and rebound, causing the moving rod 402, moving block 403, two protrusions 405, and two movable columns 406 to automatically rebound to their original positions after movement. To ensure the normal use of the two inclined plates 304 and the two positioning blocks 301, two limiting columns 5 are fixedly connected to opposite sides of the two positioning blocks 301. The surfaces of the multiple limiting columns 5 are slidably connected to the interior of the two upright plates 303. Through the multiple limiting columns 5, the two positioning blocks 301 and the two inclined plates 304 can only move to the left or right, serving as limiting and supporting functions. To improve the movement effect of the moving rod 402, moving block 403, two protrusions 405, and two movable columns 406, sliders 6 are fixedly connected to the left and right sides of the bottom of the moving block 403. The surfaces of the two sliders 6 slide against the interior of the top of the pull rod 204. The connection, via two sliders 6, allows the moving rod 402, moving block 403, two protrusions 405, and two movable columns 406 to move only forward or backward, serving as a limiting mechanism. To ensure the pull rod 204 can be fixed after moving upward or downward, positioning grooves 7 are provided on the top and bottom of both sides of the connecting column 205. The interiors of multiple positioning grooves 7 can be inserted into the surface of positioning blocks 301. Through the multiple positioning grooves 7, positioning blocks 301 are inserted into the top positioning groove 7, causing the pull rod 204 to move upward and then be fixed; positioning blocks 301 are inserted into the bottom positioning groove 7, causing the pull rod 204 to move downward and then be fixed. To increase the anti-slip capability of the support plate 201, an anti-slip pad 8 is fixedly connected to the bottom of the support plate 201. The bottom of the anti-slip pad 8 contacts the ground, increasing the friction between the support plate 201 and the ground, reducing the sliding effect of the welding device 1. The support plate 201 can be made of a relatively heavy material.

[0025] The working principle of this utility model:

[0026] When the height of welding device 1 needs to be increased, the moving rod 402 is pulled to move the moving block 403 backward. The moving block 403 causes the two protrusions 405 to move backward and the two movable columns 406 to move backward. The two movable columns 406, through compression, cause the two inclined plates 304 to move in opposite directions, and drive the two positioning blocks 301 to move and move out of the interior of the connecting column 205. At this time, the pull rod 204 can drive the support plate 201 and the anti-slip pad 8 to move downward. The movement of the moving block 403 will cause the two spring springs 404 to deform. When the pull rod 204 moves... Once the corresponding height is reached, the moving rod 402 is released, causing the moving block 403 to spring back to its original position via two spring springs 404, which in turn drive the moving rod 402, two protrusions 405, and two movable columns 406. The movement of the two positioning blocks 301 causes multiple return springs 302 to deform. Simultaneously with releasing the moving rod 402, the two positioning blocks 301 spring back to the interior of the connecting column 205 via multiple return springs 302, and drive the two inclined plates 304 to spring back to their original position, thereby causing the pull rod 204 to move downward and then be fixed, thus increasing the height between the welding device 1 and the ground.
