Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a tunnel dust removal device. Background Technology

[0002] With the rapid development of the national economy, tunnel boring machines (TBMs) have been widely used in various tunnel projects, including highway tunnels, railway tunnels, urban subway tunnels, hydraulic tunnels, and municipal pipelines, significantly improving tunnel excavation efficiency. However, tunnel excavation operations generate a large amount of dust, which is easily inhaled by on-site construction workers, seriously endangering their health.

[0003] To address this issue, the industry has introduced dust suppression devices for tunnel construction. These devices adsorb dust by spraying water mist, quickly settling dust in the tunnel air and effectively preventing excavation dust from spreading freely in the air. However, existing dust suppression equipment has some drawbacks: firstly, the spraying range is relatively small; secondly, the dust suppression range of existing equipment is fixed and difficult to adapt to tunnels of different sizes, causing some dust to easily escape the water mist coverage area and continue to spread, ultimately reducing dust suppression efficiency.

[0004] Therefore, it is of great significance to design a tunnel dust removal device that can adapt to tunnels of different sizes. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a tunnel dust removal device. This device should have the function of adjusting the spray range and have the characteristics of reliable structure and high versatility.

[0006] The technical solution of this utility model is:

[0007] A tunnel dust removal device includes a vehicle body, characterized in that: it further includes a water tank located at the rear of the vehicle body, a bracket located on top of the water tank, and a plurality of spray pipes installed on the left and right sides and top of the bracket and connected to the water tank via a hydraulic folding structure;

[0008] The hydraulic folding structure includes several support plates respectively hinged to the left and right sides and the top of the bracket; a second hydraulic rod with both ends hinged to the bracket and the support plates respectively to drive the support plates to fold; a mounting frame movably positioned on each support plate by a sliding component; a first hydraulic rod disposed on the support plate to drive the mounting frame; and a controller electrically connected to the first hydraulic rod and the second hydraulic rod.

[0009] The spray pipe is equipped with several dust removal spray nozzles arranged at equal intervals; the spray pipe is connected to the water tank in sequence through a hose, a water distributor and a water supply pipe; a water pump is provided at the inlet end of the water supply pipe.

[0010] The sliding assembly includes several guide blocks disposed on the support plate and two guide rods that slide in cooperation with the several guide blocks; one end of each of the two guide rods is fixedly connected to the mounting bracket.

[0011] The two guide rods are also arranged parallel to the first hydraulic rod and are located on both sides of the first hydraulic rod.

[0012] The spray pipe installed on the top of the bracket has an arc-shaped pipe structure, while the spray pipes installed on the left and right sides of the bracket have a straight pipe structure; the above spray pipes form an arched spray structure.

[0013] The controller is electrically connected to the water supply pump.

[0014] The beneficial effects of this utility model are:

[0015] 1. The three spray pipes in this utility model form an arched spray structure, which creates a larger spray range, effectively reduces dust dispersion, and has a significant dust removal effect.

[0016] 2. This utility model can adjust the height of the spray pipe by activating the first hydraulic rod according to the width and height of the tunnel, so as to adapt to the working conditions of tunnels of different sizes, making the device have excellent versatility.

[0017] 3. After the dust removal operation is completed, the first hydraulic rod is activated to retract the spray pipe, and then the second hydraulic rod is activated to rotate the support plate and bring it close to the bracket, thereby retracting the spray pipe. This structural design significantly reduces the size of the equipment and facilitates the transfer and storage of the device. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, a tunnel dust removal device includes a vehicle body 1, a water tank 2, a support frame 3, a hydraulic folding structure, and several spray pipes 8 (three spray pipes are shown in the figure). The water tank is mounted on the vehicle body; the support frame is located on top of the water tank; the three spray pipes are mounted on the left and right sides and the top of the support frame via the hydraulic folding structure.

[0025] like Figure 2 As shown, the hydraulic folding structure is divided into three groups, each group including a support plate 5, a mounting frame 7, a first hydraulic rod 6, a second hydraulic rod 14, and a controller. Each of the left and right sides of the support is hinged to a support plate via a vertically arranged hinge axis, and the top of the support is hinged to a support plate via a horizontally arranged hinge axis. As shown in the figure, one side of each of the three support plates is connected to the edge of the support via a hinge axis and can swing around the hinge axis; the barrel end of the second hydraulic rod is hinged to the support, and the piston rod end is hinged to the support plate. The operation of the second hydraulic rod can drive the support plate to fold on the support; the angle formed by the folding of the support plate with the side surfaces or top surface of the support is within the range of 0° to 90° (0° is the folded state; 90° is the working state). The mounting frame is movably positioned on the side of the support plate away from the hinge axis via a sliding component; the first hydraulic rod is set perpendicular to the hinge axis and its barrel end is set on the support plate, while the piston rod end is connected to the mounting frame (the spray pipe is fixed on the mounting frame). The operation of the first hydraulic rod can drive the mounting frame to move on the support plate.

[0026] The sliding assembly includes several guide blocks 15 and two guide rods 16; the guide blocks are fixed on the support plate, and the guide blocks are provided with sliding holes that slide with the guide rods; each of the two guide rods is movably positioned on the support plate through at least two guide blocks, and one end of each guide rod is fixedly connected to the mounting bracket; the two guide rods are also arranged parallel to the first hydraulic rod and are located on both sides of the first hydraulic rod (the support plates on the left and right sides of the bracket, where two guide rods are located on the upper and lower sides of a hydraulic rod; the support plate at the top of the bracket, where two guide rods are located on the left and right sides of a hydraulic rod).

[0027] like Figure 1 and Figure 3 As shown, the spray pipe is connected to the water tank via a hose 10, a water distributor 11, and a water supply pipe 12 connected in sequence. The water supply pipe is equipped with a water pump at its inlet end to deliver water from the water tank to the spray pipe.

[0028] The spray pipe is mounted on the mounting frame and has several dust-suppressing spray nozzles 9 arranged at equal intervals along its length for spraying water mist. The spray pipe mounted on the top of the frame has an arc-shaped structure with a higher center and lower ends, while the spray pipes mounted on the left and right sides of the frame have straight pipe structures and are vertically arranged; these spray pipes form an arched spray structure. The arched spray structure has a larger spray area and produces a more uniform water mist, improving the dust removal efficiency of the device.

[0029] The controller is electrically connected to the first hydraulic rod and the second hydraulic rod. By driving the first and second hydraulic rods, the tunnel dust removal device is controlled to enter the working state (the support plate is perpendicular to the surface of the bracket and the extension of the mounting frame is adapted to the current working conditions), thereby improving the dust removal efficiency of the water mist sprayed from the spray pipe; or the tunnel dust removal device is controlled to enter the folding state, reducing the size of the equipment and facilitating its transfer.

[0030] The working principle of this utility model:

[0031] 1. Drive the second hydraulic rod 14 to extend and retract via the controller, rotate the three support plates 5 to be perpendicular to the corresponding surfaces of the bracket (i.e., perpendicular to the direction of vehicle movement); then control the first hydraulic rod 6 to extend and retract, extending the spray pipe 8 on the support plate to the working length.

[0032] 2. The water supply pump 13 is turned on by the controller, and the water in the water tank 2 is sent into the water distributor 11 through the water supply pipe 12. The water distributor 11 distributes the water into the hose 10, and sends the water into the three spray pipes 8, and finally sprays it out from the dust removal spray nozzle 9 to spray dust in the tunnel. During the spraying process, the vehicle body 1 can be started to realize mobile spraying.

[0033] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
