Problems solved by technology

[0002] In modern tunnel construction, due to the accelerated speed of tunnel construction, a large amount of dust generated inside the tunnel cannot be deposited in time and floats inside the tunnel. The dust generated by the operation can be removed, and at the same time, the purpose of cooling the construction area inside the tunnel can be achieved. At the same time, most of the dust generated in the blasting is rock dust. After the adsorption and filtration of water mist and water flow, the dust in the air can be absorbed and taken away. , but because the rock dust contains a large amount of minerals, a large amount of water-soluble minerals in the rocks will dissolve in the water after passing through the water circulation system, and the water pressure will change during the transportation through the water pumps and water pipes Lead to the precipitation of minerals, and the accumulation of precipitated minerals will cause the inner wall of the water pipe to become thicker, reduce the flow of water, and even form a blockage at the nozzle, reducing the effect of air dust removal

Embodiment 1

[0024] as attached figure 1 to attach Figure 5 Shown:

[0025] The invention provides a vehicle-mounted dust removal and cooling device for tunnel construction, the structure of which includes a tire 1, a cab 2, and a carriage 3, the upper side of the tire 1 is connected to the lower end of the cab 2, and the rear of the carriage 3 is The side bolts are connected, and the compartment 3 includes a fan 31, a spray structure 32, a dust suction pipe 33, a dust removal box 34, and a water circulator 35. The fan 31 is connected to the inner bolt at the right end of the dust removal box 34. 32 is welded to the inner side of the upper end of the dust removal box 34, the dust suction pipe 33 is embedded and connected to the left end of the dust removal box 34, the lower end of the dust removal box 34 is connected to the tire 1 shaft, and the water circulator 35 is connected to the dust removal box 34 The inner side of the lower end fits together, the number of the dust suction pipe ...

Embodiment 2

[0032] as attached Image 6 to attach Figure 7 Shown:

[0033]As a further improvement of the present invention, the cleaning block e2 includes a support plate e21, a spring plate e22, a sealing block e23, and a scraping structure e24. The lower side of the support plate e21 is embedded and connected with the upper end of the tension spring e3. e22 is connected between the outer side of the scraping structure e24 and the upper side of the support plate e21, the sealing block e23 is attached to the outer side of the scraping structure e24, and the material of the sealing block e23 is collodion, which has a high compression ratio and tightness Good features, the number of scraping structures e24 is two, and they are symmetrically distributed around the support plate e21, and the shape of the scraping structures e24 is fan-shaped, so that the scraping structures e24 can be rotated and attached to both sides The inner side of the sealed cover e1 improves the cleaning power of m...

Abstract

The invention discloses vehicle-mounted dust removal and cooling equipment for tunnel construction. The vehicle-mounted dust removal and cooling equipment structurally comprises tires, a cab and a carriage, wherein the upper sides of the tires are in shaft connection with the lower end of the cab, the carriage is in bolt connection with the rear side of the cab, when water flow passes through a sealing cover, a cleaning block can be pushed upwards, after water flow is closed, a tension spring pulls the cleaning block to move downwards to remove mineral scales, then a pull rod pushes movable doors to overturn downwards to enable the movable doors to be opened to discharge the cleaned mineral scales, reset plates reset an outer cover after the water flow is started, so that the water passingamount in an inner pipe is increased, spray heads are prevented from being blocked, a scraping knife moves along the inner wall of a sealing cover, the scraping knife is supported by a top supportingcolumn to improve the scraping strength of the scraping knife, the middle of the scraping knife is pressed by a supporting fan, the mineral scales are scraped, then the scraped mineral scales are pushed away through the top supporting column to fall downwards, the cleaning strength of the inner side of the sealing cover is improved, and the water passing amount of the inner side of the sealing cover is increased.
