[0001] This utility model belongs to the field of tunnel cleaning technology, and in particular relates to a tunnel lining spraying and cleaning device. Background Technology

[0002] Tunnel lining refers to the permanent structure that supports and maintains the long-term stability and durability of a tunnel. Its functions include supporting and maintaining tunnel stability, preventing weathering of the surrounding rock, and mitigating the effects of groundwater. Therefore, tunnel lining must possess sufficient strength, durability, and certain resistance to freezing, seepage, and erosion. Tunnel lining mainly consists of the arch ring, sidewalls, invert arch, and floor slab.

[0003] Tunnel linings generally face the inside of the tunnel. In the long-term environment of poor air circulation, dust easily accumulates on the surface of the tunnel lining, requiring regular cleaning with cleaning equipment. Since the structure of tunnel linings is mostly an irregular curved surface, most existing cleaning equipment does not have adjustment functions, and linear cleaning rollers cannot effectively clean the curved surface of tunnel linings.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a tunnel lining spraying and cleaning device, such as... Figures 1-6 As shown, the tunnel lining spraying and cleaning device includes:

[0028] The main seat unit 100 includes a U-shaped seat 110, a platform 120, and a rotating shaft 130. The platform 120 and the rotating shaft 130 are disposed between the U-shaped seat 110. A first cleaning unit 410 for cleaning is provided on the U-shaped seat 110. A guide rod 140 is provided on the back of the platform 120 away from the first cleaning unit 410. A connecting support 150 is also provided on the side of the U-shaped seat 110 away from the first cleaning unit 410. The connecting support 150 can be connected to a mobile device for loading tunnel lining spraying and cleaning equipment via a base plate. The mobile device mentioned here is a truck equipped with a multi-axis robotic arm. A multi-axis robotic arm can be loaded on the truck body. The robotic arm is used to fix the main seat unit 100. A base plate for connection is provided at the end of the robotic arm. The connecting support 150 is fixed by bolts. In addition to the above solution, other truck equipment can also be used with a fixing bracket.

[0029] The deflection unit 200 includes a deflection rod 210, a connecting rod 220, and a deflection sleeve rod 230. The connecting rod 220 and the deflection sleeve rod 230 are disposed between the deflection rod 210. The deflection sleeve rod 230 is nested on the outside of the rotating shaft 130. The deflection unit 200 is provided with a second cleaning unit 420 for cleaning.

[0030] A drive assembly 300 is also provided between the main seat unit 100 and the deflection unit 200. The drive assembly 300 includes a transmission link and a pusher 330 that slides on the platform 120. The two ends of the transmission link are rotatably connected to the pusher 330 and the deflection sleeve 230, respectively. When the sliding structure slides, it pulls the main seat unit 100 and the deflection unit 200 to deflect.

[0031] In this embodiment, the drive assembly 300 pulls the main seat unit and the deflection unit to deflect. Through the linkage between the transmission link and the pusher 330 sliding on the platform, the stability of the main seat unit 100 and the deflection unit 200 during rotation is enhanced by the characteristics of the link motion structure. The deflection between the main seat unit 100 and the deflection unit 200 allows the first cleaning unit 410 and the second cleaning unit 420 on the main seat unit 100 and the deflection unit 200 to form different included angles to adapt to the curved surface of the tunnel lining, reduce cleaning dead angles, and thus achieve effective cleaning.

[0032] The deflection rod 210 and the U-shaped seat 110 are equipped with high-pressure nozzles 400. The high-pressure nozzles 400 are connected to the high-pressure water gun equipment on the truck responsible for the spraying and cleaning device for the lining of the mobile tunnel through the built-in pipes and external pipes of the deflection rod 210 and the U-shaped seat 110. The high-pressure water is delivered to the high-pressure nozzles 400 by the high-pressure water gun to complete the spraying operation.

[0033] In a preferred embodiment of this invention, the transmission link includes a first hinge rod 310 and a second support rod 320. The deflection sleeve 230 is provided with a deflection seat 340 in the middle section. One end of the second support rod 320 is fixedly connected to the deflection seat 340. The two ends of the first hinge rod 310 are rotatably connected to the pusher 330 and the second support rod 320, respectively.

[0034] In this embodiment, the deflection sleeve 230 is hollow in the center and nested on the outside of the rotating shaft 130. Since the second support rod 320 is fixedly connected to the deflection seat 340 in the middle section of the deflection sleeve 230, when the second support rod 320 deflects under the traction of the first hinge rod 310, the deflection sleeve 230 will also rotate synchronously. The second support rod 320 is perpendicular to the plane formed by the deflection rod 210 and the connecting rod 220. The end of the deflection rod 210 is also provided with a guide slide 211. The main seat unit 100 is provided with a deflection groove 101. When the deflection rod 210 rotates, the guide slide 211 will slide along the deflection groove 101.

[0035] The pushing component 330 includes a sliding block 331, a sliding rod 332, and a hinge seat 333. The sliding block 331 is disposed on both sides of the sliding rod 332, and the hinge seat 333 is disposed in the middle section of the sliding rod 332. The sliding block 331 slides on a guide rod 140 provided on the platform 120. The first hinge rod 310 is hinged to the hinge seat 333. The platform 120 is also provided with a push rod 160, which is connected to the hinge seat 333. The push rod 160 is driven by electric or hydraulic technology and is driven to move by a control terminal device. The hinge seat 333, the sliding block 331, and the sliding rod 332 slide along the guide rod 140 under the action of the thrust. During the movement of the hinge seat 333, the first hinge rod 310 and the second support rod 320 deflect under the action of the connecting rod. When the second support rod 320 rotates, it synchronously pulls the deflection unit 200 to deflect as a whole.

[0036] As a preferred embodiment of this embodiment, the first cleaning unit 410 includes a first side platform 411, a second side platform 412, and a cleaning roller 413 disposed between the first side platform 411 and the second side platform 412. The number of cleaning rollers 413 is not less than one set. The cleaning roller 413 is composed of a rotating shaft and a roller. The rotating shaft extends into the first side platform 411 and the second side platform 412 and is fixed by bearings respectively. The structure here is a well-known structure and will not be described in detail.

[0037] A drive motor 414 is provided on the outer side of the first side platform 411. When the number of cleaning rollers 413 is one set, the part of the rotating shaft of the cleaning roller 413 extending into the first side platform 411 is connected to the motor shaft of the drive motor 414 to realize power transmission. When the number of cleaning rollers 413 is multiple sets, a transmission pulley is also provided on the rotating shaft of the cleaning roller 413. Only the rotating shaft of one set of cleaning rollers 413 is connected to the motor shaft of the drive motor 414. The other sets achieve synchronous rotation with the help of the transmission pulley and transmission belt structure. For example, there are two sets of transmission pulleys on the rotating shaft, and power is transmitted between adjacent cleaning rollers 413 through the transmission belt.

[0038] The outer side of the roller is equipped with flexible bristles. During rotation, the bristles will come into contact with the inner wall of the tunnel lining by rotating the roller itself. This is similar to the cleaning principle of the roller and bristles in an autonomous car wash. After the main seat unit 100 and the deflection unit 200 form a certain angle, the arc surface of the tunnel lining is adaptively adjusted by the bristles.

[0039] The second cleaning unit 420 has the same structure as the first cleaning unit 410, and the second cleaning unit 420 is mounted on the U-shaped seat 110; the high-pressure nozzle 400 needs to be positioned to avoid the first cleaning unit 410 and the second cleaning unit 420, especially the motor position, and the drive motor 414 adopts a waterproof design.
