Description

TECHNICAL FIELD

[0001] The utility model relates to the field of welding protection, specifically, relates to a protection device for U-shaped support assembly welding. BACKGROUND

[0002] U-shaped support assembly usually refers to the support structure formed by taking U-shaped steel as the main material, and is widely applied to multiple fields such as coal mines, tunnels and underground engineering. When the U-shaped support is welded through a welding device, smoke will diffuse in the air, which is easy to be inhaled by workers, so protection is needed during welding.

[0003] After retrieval, the prior art discloses a protection device for instrument panel beam support assembly welding in Chinese patent with patent publication number CN219818515U, which comprises a base, a welding structure is arranged at the upper end of the base, a glass cover is fixedly installed at the upper end of the base, a movable glass plate is movably installed on one side of the glass cover, a connecting strip is fixedly installed at the upper end of the base, a dust suction cover is fixedly installed at the upper end of the glass cover, a dust suction box is fixedly installed on one side of the glass cover, when the rotating shaft rotates, the rotating shaft drives the transmission gear plate to rotate, the transmission gear plate drives the rotating rod to rotate through the engagement gear, the rotating rod drives the cam to rotate, the longer end of the cam lifts the top strip upward, the top strip drives the movable magnetic strip and the connecting magnetic strip to drive the dust collection net bag to move upward through the top rod, when the longer end of the cam lifts the top strip, the dust collection net bag moves downward, so that the dust collection net bag repeatedly moves upward and downward, avoiding the blockage of the dust collection net bag and affecting the dust collection effect. However, the device still has the following defects:

[0004] (1) However, when the glass cover is installed, the worker needs to manually move the connecting rod to make the plug block disengage from the slot, and then place the glass cover on one side of the connecting rod. When the glass cover needs to be disassembled, the connecting rod needs to be moved in the opposite direction to make the plug block disengage from the slot again, and then the glass cover is removed. The operation steps are complicated and affect the disassembly efficiency.

[0005] (2) However, when the device collects waste gas, it lacks a device that can filter waste gas. When the waste gas is directly discharged, it will still be inhaled by workers, which will affect the health of workers.

[0006] Therefore, we improve it and propose a protection device for U-shaped support assembly welding. UTILITY MODEL CONTENTS

This allows for quick installation of the protective shell. To disassemble the protective shell, pull the limiting plate so that the trapezoidal block is on one side of the inverted trapezoidal block.

[0034] As Figures 1-5 shown, the utility model provides a protection device for U-shaped support assembly welding, including welding table body 1, the top of welding table body 1 is provided with protection mechanism 2, the top of protection mechanism 2 is provided with exhaust purification assembly 3;

[0035] As Figure 3 and Figure 5As shown, the protection mechanism 2 comprises a protection shell 201, a positioning plate 202, an extension plate 203, a sliding rod 204, a limiting plate 205, a spring 206, a trapezoidal block 207, an inverted trapezoidal block 208 and an elastic sheet 209. The protection shell 201 is arranged on the top of the welding table body 1. The positioning plate 202 is bolted on the side wall of the welding table body 1. The extension plate 203 is welded on the side wall of the positioning plate 202. The sliding rod 204 is arranged on one side of the extension plate 203. The limiting plate 205 is welded on one end of the sliding rod 204 close to the positioning plate 202. The spring 206 is arranged outside the sliding rod 204 and is welded on the side wall of the extension plate 203. The trapezoidal block 207 is welded on one end of the sliding rod 204 close to the protection shell 201. The inverted trapezoidal block 208 is bolted on the side wall of the protection shell 201 below the trapezoidal block 207. The elastic sheet 209 is welded on the bottom of the inverted trapezoidal block 208 and is in contact with the top of the welding table body 1. A hole is formed in the extension plate 203. The sliding rod 204 is inserted into the hole and can axially slide. The inclined end of the trapezoidal block 207 faces upward. The inclined end of the inverted trapezoidal block 208 faces downward. When protection is needed, the protection shell 201 is lifted, and then the inverted trapezoidal block 208 is aligned with the trapezoidal block 207. At this time, the protection shell 201 is pressed down so that the inclined surface of the inverted trapezoidal block 208 is in contact with the inclined surface of the trapezoidal block 207. Then the trapezoidal block 207 moves to one side, and then the spring 206 contracts. During the contraction of the spring 206, the inclined surface of the inverted trapezoidal block 208 moves downward relative to the inclined surface of the trapezoidal block 207. When the spring 206 contracts to a certain extent, the inverted trapezoidal block 208 separates from the trapezoidal block 207 and reaches below the trapezoidal block 207, so that the trapezoidal block 207 moves toward the protection shell 201 along the upper surface of the inverted trapezoidal block 208, achieving the effect of pressing the trapezoidal block 207 against the inverted trapezoidal block 208, thereby fixing the protection shell 201. When the protection shell 201 needs to be disassembled, the limiting plate 205 is pulled to move the sliding rod 204 until the trapezoidal block 207 is separated from the inverted trapezoidal block 208. At this time, the elastic sheet 209 will pop up the protection shell 201, so that the protection shell 201 can be quickly disassembled. The operation is convenient, fast and practical.
