Description

Technical Field

[0001] The utility model relates to the technical field of vehicle detection, and specifically relates to a dust removal device for an automobile detection pit. Background Art

[0002] In an automobile repair workshop or a detection station, it is usually necessary to drive a vehicle into a pit for chassis inspection, repair and other work. During these work processes, a large amount of pollutants such as dust and metal chips will be generated, which not only affect the working environment, but may also cause equipment damage and even pose a threat to human health.

[0003] At present, there are mainly two dust removal methods used in automobile detection pits: one is manual cleaning, which is inefficient and difficult to remove fine particles; the other is to use a fixed dust suction device, although it can solve the dust problem to a certain extent, but there are the following disadvantages:

[0004] 1. Fixed dust suction devices often have difficulty covering the entire pit area, resulting in ineffective cleaning of dust in some areas.

[0005] 2. The position of the dust suction port is fixed, and its adaptability to different vehicle models and detection requirements is poor.

[0006] 3. The collection and treatment of dust after dust removal are inconvenient, and it is easy to cause secondary pollution. Summary of the Invention

[0007] The technical problem to be solved by the utility model is to provide a dust removal device for an automobile detection pit to overcome the above problems existing in the prior art. The device should be able to achieve efficient and flexible dust removal, and facilitate the subsequent collection and treatment of dust, so as to improve the working environment and work efficiency.

[0008] To solve the above technical problems, the technical solution adopted by the utility model is: a dust removal device for an automobile detection pit, including vehicle positioning bridges arranged on both sides of the pit. There are chutes on the vehicle positioning bridges, and sliders are arranged in the chutes. A dust suction pipe is arranged between the two sliders, and the dust suction pipe spans across the pit and is provided with a plurality of negative pressure adsorption nozzles facing different directions on the dust suction pipe above the pit;

[0009] One end of the dust suction pipe is connected to a dust adsorption box through a hose.

[0010] In a preferred solution, one end of the bottom of the vehicle positioning bridge is provided with a slot, and a telescopic control mechanism is arranged in the slot. A push rod passing through the slot into the chute is arranged on the telescopic control mechanism, and the end of the push rod is fixedly connected to the slider to control the slider to move in the chute.

[0011] In a preferred embodiment, an inlet dust pipe is provided outside the dust adsorption box. The output end of the hose is connected to the inlet dust pipe.

Specific implementation mode

[0025] As Figures 1-3 shown in the figure, a dust removal device for an automobile inspection pit includes vehicle positioning bridges 1 arranged on both sides of the pit. A chute 2 is provided on the vehicle positioning bridge 1, a slider 3 is arranged in the chute 2, and a dust suction pipe 4 is arranged between two sliders 3. The dust suction pipe 4 spans across the pit and a plurality of negative pressure suction nozzles 5 facing different directions are arranged on the dust suction pipe 4 above the pit;

[0026] One end of the dust suction pipe 4 is connected to the dust adsorption box 8 through a hose 9.

[0027] In a preferred solution, a slot is provided at the bottom of one end of the vehicle positioning bridge 1, a telescopic control mechanism 6 is arranged in the slot, a push rod 7 penetrating into the chute 2 is arranged on the telescopic control mechanism 6, and the end of the push rod 7 is fixedly connected to the slider 3 to control the slider 3 to move in the chute 2.

[0028] In a preferred solution, a dust inlet pipe 10 is arranged outside the dust adsorption box 8, the output end of the hose 9 is connected to the dust inlet pipe 10, a negative pressure pump 11 is arranged on the dust inlet pipe 10, and the output end of the dust inlet pipe 10 penetrates from the top of the dust adsorption box 8 into the dust adsorption box 8.

[0029] In a preferred solution, a water pump 12 is arranged at the bottom inside the dust adsorption box 8, a vertically upward water supply pipe 121 is arranged on the water pump 12, a spray head 13 is arranged at the upper end of the water supply pipe 121, and the spray head 13 is arranged close to the output end of the dust inlet pipe 10.

[0030] In a preferred solution, an inclined filter screen 14 is arranged inside the dust adsorption box 8, and the water supply pipe 121 passes through the filter screen 14.

[0031] In a preferred solution, a movable frame 16 is arranged above the filter screen 14. A water supply pipe through groove 161 is arranged at one end of the movable frame 16, and the water supply pipe 121 passes through the water supply pipe through groove 161. A pull rod 162 is arranged on the end face of the other end of the movable frame 16.

[0032] In a preferred solution, an extension pipe body 15 is arranged on one side wall of the dust adsorption box 8, and the pull rod 162 at one end of the movable frame 16 extends into the extension pipe body 15.

[0033] In a preferred embodiment, a drain pipe 801 is provided at the bottom of the side wall of the dust adsorption box 8.

[0034] During the vehicle inspection process, the vehicle is in a running state, and the generated exhaust gas and the impact of the exhaust gas will cause dust to be generated in the pit. When dust removal is required, the operator first activates the telescopic control mechanism 6, and the push rod 7 is used to push the slider 3 to move in the chute 2, so as to adjust the position of the dust suction pipe 4 to make it closer to the area to be cleaned. The reciprocating movement of the dust suction pipe 4 can also be realized through the telescopic control mechanism 6. During the process, the negative pressure pump 11 is in a starting state, and it will form a negative pressure area near the dust suction pipe 4, so that the dust-containing gas is sucked into the dust suction pipe 4 through the negative pressure adsorption nozzle and enters the dust adsorption box through the hose 9.

[0035] Inside the dust adsorption box 8, the dust-containing gas first passes through the filter inclined net 14, and larger dust particles will be intercepted. Subsequently, the gas continues to flow upward and passes through the water mist sprayed by the spray head 13, so that the remaining dust particles settle due to the increase in wet weight. The settled dust will finally fall on the filter inclined net 14 and be removed during regular cleaning (by pulling the pull rod 162 to pull out the movable frame 16 and drive the solid impurities on the filter inclined net 14 to be discharged).

[0036] The clean gas that has been filtered and washed finally discharges from the top of the dust adsorption box 8, thus realizing an efficient dust removal process.
