Description

Technical Field

[0001] This application belongs to the field of waterproofing technology for tunnel engineering, specifically relating to a waterproof coating spraying device for tunnel leakage control. Background Technology

[0002] Tunnel engineering is a crucial component of transportation infrastructure construction, and its waterproofing performance directly impacts the tunnel's service life and operational safety. Tunnel leakage is a common quality issue in tunnel engineering, leading to a series of problems such as lining structure deterioration, steel reinforcement corrosion, and slippery road surfaces, seriously threatening traffic safety.

[0003] Currently, tunnel leakage control mainly employs two methods: grouting and surface waterproofing. Among them, the surface waterproofing method involves applying waterproof coating to the surface of the tunnel lining to form a continuous waterproof layer, preventing groundwater from seeping into the tunnel interior.

[0004] The inventors discovered that the spraying of waterproof coatings is usually done manually, which has technical defects such as high labor intensity, low construction efficiency, and difficulty in guaranteeing construction quality. It is easy to have problems such as uneven thickness of waterproof coating, missed coating, and dripping, which affect the effectiveness of tunnel leakage control. Utility Model Content

[0010] Multiple alignment plates are arranged side by side on the lifting plate along a straight line. The plate surface of each alignment plate faces the positioning member and has an arc-shaped guide hole that runs through the thickness direction.

[0011] The sprayer is adapted to be inserted into any one of the guide holes, and one of the guide holes is set concentrically with the arc-shaped wall of the tunnel so that the positioning member and the sprayer move synchronously in the vertical direction during the reciprocating movement of the sprayer in the straight line direction.

[0012] In one possible implementation, the lifting drive component includes:

[0013] Two cross-shaped drive arms are slidably connected at both ends of their lower sides to the upper side of the trolley, and at both ends of their upper sides to the lower side of the lifting plate; and

[0015] When the rotation drive component drives the traction roller to rotate, the two pull belts can be wound around the traction roller simultaneously to drive the lower ends of the two transmission arms to move towards each other; or, the two pull belts can be detached from the traction roller to cause the lower ends of the two transmission arms to move away from each other under the pressure of the lifting plate.

[0016] In one possible implementation, the rotation drive component includes:

[0017] The driven gear is coaxially mounted on the traction roller; and

[0018] A first rotating motor is fixedly mounted on the trolley, and its power output axis is parallel to the axis of the traction roller. The power output end of the first rotating motor has a driving gear that meshes with the driven gear.

[0020] In one possible implementation, a telescopic rod is provided between the lifting plate and the trolley, the axis of the telescopic rod being parallel to the vertical direction, and the upper and lower ends being fixedly connected to the lower side of the lifting plate and the upper side of the trolley, respectively.

[0021] In one possible implementation, the sprayer is connected to the hose via a connector, and both the connector and the hose, as well as the connector and the sprayer, are detachably connected.

[0022] In one possible implementation, the upper side of the lifting plate has an upwardly extending protrusion, the storage tank and the protrusion are respectively disposed on both sides of the sprayer, and the hose passes around the protrusion and is connected to the sprayer.

[0032] One end of the connecting rod is fixedly connected to the slider, and the other end is slidably connected to the positioning member in the up-down direction.

[0033] In this embodiment, the trolley can be moved to below the leakage area, and then the lifting plate is moved upward by the lifting drive component. At the same time, the orientation and position of the trolley can be manually adjusted so that one of the guide holes and the arc surface of the leakage wall are concentrically set. Based on this, the positioning component is driven to move back and forth by the reciprocating drive component, so that the sprayer can move along the crack of the leakage wall.

[0051] Please refer to the following: Figures 1 to 10 The waterproof coating spraying equipment for tunnel leakage control provided in this application will now be described. The waterproof coating spraying equipment for tunnel leakage control proposed in this application includes a trolley 1, a sprayer 2, and multiple alignment plates 3.

[0052] The trolley 1 is used to move on the tunnel floor or to be fixed below the leakage area. A lifting plate 4 is located on top of the trolley 1, and this lifting plate 4 is driven by a lifting drive component 5 for moving it vertically. A storage tank 41 for storing paint is fixedly mounted on the lifting plate 4. A positioning component 42 is also slidably connected to the lifting plate 4 along a straight line. This positioning component 42 is driven by a reciprocating drive component 6 for reciprocating movement, and the positioning component 42 also has a degree of freedom to move vertically relative to the lifting plate 4.

[0053] The sprayer 2 is slidably mounted on the lifting member in a straight line and is fixedly connected to the aforementioned positioning member 42 for synchronous movement. The sprayer 2 is connected to the storage tank 41 through a flexible hose 21 to realize the input of paint; based on this, the sprayer 2 also has an upward-extending discharge pipe 22 for discharging paint to realize the upward output of paint.

[0054] Multiple alignment plates 3 are arranged side by side on the lifting plate 4 along a straight line. The plate surface of each alignment plate 3 faces the positioning member 42 and has an arc-shaped guide hole 31 that runs through the thickness direction.

[0055] With manual adjustment, the sprayer 2 is suitable to be inserted into any one of the guide holes 31, and one of the guide holes 31 is set concentrically with the arc-shaped wall of the tunnel so that during the reciprocating movement of the sprayer 2 in a straight line, the positioning member 42 and the sprayer 2 move synchronously in the up and down direction.

[0056] In this embodiment, the trolley 1 can be moved to the area below the leakage zone, and then the lifting plate 4 is moved upward by the lifting drive component 5. At the same time, the orientation and position of the trolley 1 can be manually adjusted so that one of the guide holes 31 and the arc surface of the leakage wall are concentrically set. Based on this, the positioning component 42 is moved back and forth by the reciprocating drive component 6, which enables the sprayer 2 to move along the crack of the leakage wall. At the same time, the sprayer 2 moves along an arc trajectory under the action of the guide hole 31, thereby ensuring that the distance between the discharge pipe 22 and the leakage wall remains unchanged and ensuring the spraying effect.

The storage tank 41 and the protrusion 43 are respectively arranged on both sides of the sprayer 2. The hose 21 passes around the protrusion 43 and is connected to the sprayer 2.

[0068] In some embodiments, such as Figure 6 As shown, the reciprocating drive component 6 includes a drive screw 61 and a driven nut 62.

[0069] The drive screw 61 is rotatably mounted on the upper side of the lifting plate 4, and its axis is parallel to the straight line direction.
