Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to a bracket welding device for elevator processing. Background Art

[0002] An elevator is a permanent transportation equipment that serves several specific floors in a building, with its car running on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type elevators, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment that serve specified floors. A vertical elevator has a car that runs between at least two rows of rigid guide rails that are perpendicular or inclined at an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods.

[0003] When the elevator is being processed, in order to ensure its stability, it is necessary to weld the bracket at its specific position to form a stable triangular structure, which can greatly improve the stability of the elevator and ensure the safety of the elevator. In the prior art, the bracket is welded at the required position by manually holding a welding gun. We know that the quality of welding directly affects the stability of the elevator. Therefore, general novice workers are not competent for this task. They cannot ensure the stability of their hands during welding, which leads to uneven welding and other problems that affect the welding performance. Therefore, it can only be carried out by experienced workers, which results in low bracket welding efficiency. For this reason, we propose a bracket welding device for elevator processing.

Then, the adjusting cylinder is started, and the adjusting cylinder drives the welding gun to move to the welding position. Further, the electric guide rail is started, and the electric guide rail drives the slider to move at a constant speed and track on its outer wall, and the movement of the slider drives the welding gun to move, thereby realizing the track fixing of the welding gun, ensuring the stability of welding and improving the quality of welding.

After the welding smoke enters the air cavity, the gas can only flow out through the filter due to the flexible sealing connection between the filter screens. Therefore, when the gas passes through the filter screen, the solid particles in the gas will be intercepted by the filter screen, thereby preventing the solid particles from flowing out to the outside air, thereby protecting the operators and the environment. Some large-diameter particles among the intercepted particles will fall to the bottom of the air cavity under the action of gravity, and then fall into the collection frame under the action of the flexible sealing connection and the guide block to be collected, while some small particles will be stuck in the filter screen. Furthermore, as the slider moves to contact with the push rod, the The push rod will be squeezed to move outward, that is, the filter will be pushed outward, and the movement of the filter will cause the cleaning cone to be inserted into its aperture, so that the small particles are discharged and fall into the aggregate frame through gravity to complete the collection, and when the slider moves to contact with the top of the aggregate frame, it will cause the aggregate frame to move downward, and after the aggregate frame moves downward, the adsorption part at its bottom will engage with the magnetic part, and then when the aggregate frame is reset upward, the bottom plate will rotate due to the limit, and after the bottom plate is rotated and opened, the material inside the aggregate frame will be discharged, thereby realizing the automatic discharge and cleaning effect of the material, and when the bottom plate rotates to the limit, as the aggregate frame continues to move, the bottom plate will be disengaged from the magnetic part and reset, thereby ensuring its continuous work.

[0040] See also Figure 7-8The end surface of the wrapping ring 201 is also equipped with a cleaning and shocking integrated component 6, which generates vibration while scraping and cleaning the end surface of the wrapping ring 201, thereby playing an auxiliary cleaning effect of the filter screen 401;

[0041] Specifically, the integrated cleaning and shocking component 6 includes a horizontal plate 601 fixedly connected to the outer wall of the electric guide rail 203, and a scraper 602 extending to the end face of the wrapping ring 201 is fixed at the bottom end of the horizontal plate 601, and the end faces of the wrapping ring 201 on both sides of the air suction port 305 are inclined inward, and the bottom end of the scraper 602 is adapted to the end face of the wrapping ring 201, and the outer wall of the suction fan 301 is fixedly connected to an extension plate 603 extending downward, and the inner end face of the extension plate 603 is fixedly provided with a plurality of force blocks 604 connected to the inside of the extension plate 603 by spring sliding reset, and the outer side of the force block 604 is located on the side wall of the wrapping ring 201, and extrusion blocks 605 are evenly distributed.

[0042] The working principle of the present invention is as follows: first, the whole device is fixed at the welding position by the magnetic attraction plate 101, and then the wrapping ring 201 is moved to a suitable position by adjusting the two sets of bolts, and then the adjusting cylinder 205 is started, and the adjusting cylinder 205 drives the welding gun 206 to move to the welding position;

[0043] Further, the electric guide rail 203 is started, and the electric guide rail 203 drives the slider 204 to move at a fixed speed and fixed track on its outer wall, and the movement of the slider 204 drives the welding gun 206 to move, thereby achieving fixed track of the welding gun 206, ensuring the stability of welding and improving the quality of welding;

[0044] When welding, the suction fan 301 is started, and the suction force generated by the suction fan 301 acts on the welding point through the suction port 305, so that the smoke and sparks generated by welding can be sucked into the air cavity 304 through the suction port 305 for filtration and purification, and then flow into the suction pipe 302 through the connecting pipe 303, and finally discharged into the outside air;

[0045] When the welding smoke enters the air cavity 304, the gas can only flow out through the filter 401 due to the presence of the flexible sealing connection part 402 between the filter 401. Therefore, when the gas passes through the filter 401, the solid particles in the gas will be intercepted by the filter 401, thereby preventing the solid particles from flowing out to the outside air, thereby protecting the workers and the environment. Among the intercepted particles, some large-diameter particles will fall to the bottom of the air cavity 304 under the action of gravity, and then fall into the collection frame 501 under the action of the flexible sealing connection part 402 and the guide block 502 to be collected, while some small particles will be stuck in the filter 401.

[0046] Furthermore, as the slider 204 moves to contact the push rod 403, it will squeeze the push rod 403 to move outward, that is, push the filter screen 401 to move outward, and the movement of the filter screen 401 will cause the cleaning cone 405 to be inserted into its aperture, so that the small particles are discharged and fall into the aggregate frame 501 by gravity to complete collection;

[0047] When the slider 204 moves to contact the top of the material collection frame 501, it will cause the material collection frame 501 to move downward. After the material collection frame 501 moves downward, the adsorption portion 504 of the bottom plate 503 at its bottom end will be attracted to the magnetic attraction portion 505, and then when the material collection frame 501 is reset upward, the bottom plate 503 will rotate due to the limit. After the bottom plate 503 is rotated and opened, the material inside the material collection frame 501 will be discharged, thereby achieving an automatic discharge and cleaning effect of the material. After the bottom plate 503 rotates to the limit, as the material collection frame 501 continues to move, the bottom plate 503 will be separated from the attraction with the magnetic attraction portion 505 and reset, thereby ensuring its continuous operation;

[0048] It is worth noting that when the slider 204 moves, the horizontal plate 601 connected to its outer wall will move synchronously with it, and the movement of the horizontal plate 601 will drive the scraper 602 to move, and the movement of the scraper 602 will scrape off the spark particles adhering to the end surface of the wrapping ring 201, thereby achieving a cleaning effect on the wrapping ring 201. Since the end surface of the wrapping ring 201 is set to be inclined, the particles scraped by the scraper 602 will flow to the air suction port 305 under the action of the inclined end surface, so that the scraped particles finally flow into the air cavity 304 to be collected and cleaned;

[0049] Furthermore, the movement of the horizontal plate 601 will also drive the movement of the extension plate 603, so that the force block 604 on the end face of the extension plate 603 moves to contact with the extrusion block 605. Under the extrusion effect of the extrusion block 605, the force block 604 will retract into the extension plate 603, and when the force block 604 moves to no longer contact with the extrusion block 605, the force block 604 will pop out, and the reciprocating cycle will achieve a shocking effect on the wrapping ring 201. Through the resonance effect, it can shock the filter 401 and assist in its cleaning.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
