Technical Field

[0001] The utility model relates to the technical field of welding fume treatment, and more particularly to a mobile welding fume purifier with high efficiency dust collection device. Background Art

[0002] The mobile welding fume purifier high-efficiency dust collection device is a device designed specifically for industrial needs. It is used for local welding and cutting fume treatment. It has movable wheels at the bottom and can be moved to different welding positions. It has a bendable and positionable dust collection tube for flexible use.

[0003] The currently used mobile welding fume suction devices are usually moved to the vicinity of the welding table, and the distance between the suction port and the welding position is adjusted by manually turning the suction tube. The position of the suction port is fixed by the bending and shaping characteristics of the suction tube itself. However, this limiting method is prone to reduced stability after long-term bending operation. In addition, the device is prone to vibration during the fume extraction process, causing the position of the suction port to shift, and falling phenomenon will affect the welding operation. In view of this, we propose a mobile welding fume purifier with high efficiency suction device. Utility Model Content

Under the adjustable height of the lifting frame, the connecting hanger can be adjusted to a position higher than the dust suction pipe, so as to facilitate the lifting and limiting operation of the dust suction pipe. With the setting of the folding frame, the connecting hanger can be adjusted to a position corresponding to the pipe mouth of the dust suction pipe, thereby achieving a flexible structural coordination effect, so that the connection support effect can be achieved when the dust suction pipe is adjusted to different heights for dust collection. The height position of the hook can be adjusted by winding the sling through the motor to control the winding rod, so that the position of the dust suction pipe mouth can be pulled up. Under the characteristic of the dust suction pipe falling under its own weight, the position can be kept stable, the probability of shaking and moving downward is reduced, and the impact on the welding operation is reduced.

[0023] like Figures 1 to 4As shown, the utility model relates to a mobile welding fume purifier with high-efficiency dust collection device, which includes a dust collection device body consisting of a dust collection bucket 1 and a dust collection pipe 2. A lifting frame 3 is fixedly provided on the top of the dust collection bucket 1, and a folding frame 4 is installed on the top of the lifting frame 3. The side end of the folding frame 4 is fixedly provided with a connecting hanger 5 that can be connected to the dust collection pipe 2; the height of the folding frame 4 can be adjusted by setting the lifting frame 3, so that the connecting hanger 5 can have sufficient distance to adjust the position of hanging with the dust collection pipe 2, thereby achieving the effect of auxiliary support.

[0024] The connecting hanger 5 includes a U-shaped frame 501, and a motor 502 is fixedly provided on one side of the U-shaped frame 501. The output end of the motor 502 is equipped with a winding rod 503 which is rotatably connected to the side wall of the U-shaped frame 501. A sling 504 is wound on the rod wall of the winding rod 503, and a hook 7 is fixed at the lower end of the sling 504. The operation of the motor 502 can control the rotation of the winding rod 503 to wind or loosen the sling 504, thereby adjusting the position of the hook 7.

[0025] A ring 6 is fixed on the outer wall of the nozzle of the dust suction pipe 2, and two hanging straps 601 connected to the hook 7 are fixed on the top of the ring 6; the connection between the hanging straps 601 and the hook 7 can make the folding frame 4 and the dust suction pipe 2 structure, thereby maintaining the stability of the position of the dust suction pipe 2 under the support of the folding frame 4.

[0026] In an embodiment of the present utility model, an adapter 301 is fixedly provided at the bottom of the lifting frame 3, which is rotatably connected to the folding frame 4. A locking groove 302 is provided on one side of the lifting frame 3 close to the folding frame 4. A rotating seat 401 is fixedly provided at the bottom of the folding frame 4. A support rod 402 is rotatably installed on the inner side of the rotating seat 401. A blocking block 403 is fixedly provided at the lower end of the support rod 402, which is combined with the top of the locking groove 302. Through the provision of the adapter 301, the folding frame 4 can be flipped to achieve an adjustable position. During use, the blocking block 403 at the side end of the support rod 402 is combined with the locking groove 302 to achieve a positioning support effect, keep the position fixed, and at the same time, it is easy to separate and release the support restriction.

[0027] In an embodiment of the present utility model, a support plate 303 is fixedly provided on one side of the lifting frame 3 close to the folding frame 4, which is in contact with the lower end of the connecting hanger 5 after it is flipped over, and a limiting plate 304 is integrally formed on the top of the side end of the support plate 303, which is in contact with the inner wall of the connecting hanger 5; through the cooperation between the support plate 303 and the limiting plate 304, the position of the connecting hanger 5 after flipping can be supported, further enhancing the position limiting effect.

[0028] In an embodiment of the present invention, the shape of the hook 7 is a T-shape with an arc, and arc-shaped guard bars are fixed on both sides of the vertical part of the hook 7; the T-shaped structure with an arc can achieve a limiting effect when hanging the hanging strap 601, and the design of the guard bar can limit the hanging diameter, making it difficult for the hanging strap 601 to separate from the hook 7.

[0029] In an embodiment of the present invention, the folding frame 4 is composed of several fixed tubes of different sizes, and the fixed tubes are square in shape. Anti-slip pads are provided on the sides of the joints of two fixed tubes. Multiple sections of fixed tubes are connected to facilitate adjustment of the overall length. The design of the anti-slip pads can enhance the resistance to telescopic adjustment movement and improve the stability of the position after adjustment.

[0030] In an embodiment of the present invention, a hanging hole is provided on the side wall of the hanging strap 601 to be combined with the hook 7, and the hanging hole is in the shape of an elongated strip. The height of the hanging hole is greater than the height of the hook 7. The elongated hanging hole is convenient for the hook 7 to pass through, making the hanging and connecting operation convenient.

[0031] Working principle: This embodiment provides a mobile welding fume purifier with high efficiency dust collection. When in use, first move the whole to the position of the welding table. After adjusting the placement, you can manually bend the position of the dust collection tube 2 so that the dust collection port is aligned with the welding position on the welding table and a certain distance away from the welding table. After completion, you can first adjust the height of the folding frame 4 through the lifting frame 3, and then adjust the position of the connecting hanger 5 by stretching the folding frame 4 so that the connecting hanger 5 is aligned with the position of the ring 6 on the outer wall of the dust collection tube 2. Then start the motor 502 to rotate the winding rod 503 to extend the sling 504 downward, so that the hook 7 is in contact with the sling 601 at the top of the ring 6, and then manually hang the two together. After completion, tighten the sling 504. This can provide auxiliary support for the dust suction pipe 2 and maintain the stability of the dust suction port position, thereby reducing the probability of downward movement during welding work and maintaining a stable position for dust suction work. When the dust suction device body is not in use, the folding frame 4 can be flipped upward first to give the support rod 402 space to flip downward, making it convenient for the block 403 to separate from the positioning groove 302, thereby releasing the support for the folding frame 4. Then the folding frame 4 can be flipped downward to make the connecting hanger 5 close to one side of the lifting frame 3. After it is close, the folding frame 4 is pulled down to extend it. This can make the lower end of the connecting hanger 5 fit against the top of the support plate 303, thereby achieving the effect of support and limiting. Then the lifting frame 3 can be reset, which can reduce the occupied space and facilitate storage.
