Abstract
Description
Technical Field
[0001] The present invention relates to the field of waterproof board laying and hanging, and specifically to an intelligent automatic waterproof board laying and hanging trolley. Background Art
[0002] The laying and hanging of waterproof boards means that between the primary support and the secondary lining of the tunnel lining structure, a waterproof board is laid and hung on the tunnel wall through a certain fixing method to form a complete waterproof barrier, effectively preventing groundwater from seeping into the tunnel interior, protecting the tunnel lining structure from water erosion, improving the durability and service life of the tunnel, and at the same time providing a dry environment inside the tunnel to ensure the normal use function of the tunnel;
[0003] Before laying the waterproof board, construction workers will use measuring tools, such as steel tape measures, to measure and mark on the processed primary support surface according to the design requirements. According to the width of the waterproof board and the requirements of the overlapping width, determine the laying position and boundary of each waterproof board, and use chalk or other markable tools to make clear marks on the primary support surface to guide the laying operation of the waterproof board and ensure that there is enough overlapping width between adjacent waterproof boards; when laying the waterproof board, construction workers will lay the waterproof board according to the marked position, one person is responsible for unfolding the waterproof board, and another person is beside to supervise and guide to ensure that the laying direction of the waterproof board is correct and the edges are aligned with the marked line; the tunnel surface is not completely flat, there are some uneven places, and manual pressing can be used to deal with these parts specifically, and use hands or simple tools to press the waterproof board into the gaps and depressions to make the waterproof board fit more closely with the tunnel surface, thereby improving the waterproof effect.
[0004] For traditional laying and hanging trolleys, the waterproof board coil on the winding wheel moves along the arc track with the trolley and slowly releases the waterproof board. If the winding wheel directly applies pressure to the waterproof board to squeeze the tunnel wall, although the waterproof board can be attached to the tunnel, due to the uneven rock surface of the tunnel wall, the waterproof board is easily worn under the large applied pressure, affecting the waterproof performance; if there is a certain distance between the winding wheel and the tunnel wall, although the waterproof board can adapt to the tunnel contour in the natural hanging state and reduce local stress concentration, manual pressing or the use of pressing tools is required to make the waterproof board fit more closely with the tunnel surface, which results in low work efficiency and time-consuming and laborious. Summary of the Invention
[0005] Aiming at the deficiencies of the prior art, the present invention provides an intelligent automatic waterproof board laying and hanging trolley, which solves the problems that direct extrusion and fitting can fix the waterproof board, but due to the uneven tunnel wall, the waterproof board is easily worn and the waterproof performance is affected, and leaving a distance for natural hanging can reduce stress concentration, but manual assistance is required for pressing, resulting in a large labor intensity.
[0006] To achieve the above object, the present invention is realized by the following technical solutions: An intelligent automatic waterproof board hanging trolley, comprising a trolley moving along a trolley track, a bracket, and a winding wheel. The winding wheel releases a waterproof board coil when moving with the trolley. A housing is fixedly installed on the telescopic arm of the bracket. An elastic layer for rotation is provided inside the housing. The elastic layer is a circular closed structure filled with gas inside. A plurality of pneumatic plunger structures arranged in sequence are also provided inside the housing. A rolling body is provided at the free end of the pneumatic plunger structure. The rolling body presses against the elastic layer and forms a convex structure thereon.
[0007] When the elastic layer moves towards the waterproof board on the tunnel, a surface contact area for the rolling body to move is formed between the two. The pneumatic plunger structure applies a reverse force to the elastic layer through the rolling body by boosting pressure, and presses the waterproof board into the concave area of the tunnel; when the free end of any pneumatic plunger structure moves to the maximum stroke, the pneumatic plunger structure stops boosting pressure.
[0008] Preferably, a turntable is rotatably installed inside the housing. Both ends of the elastic layer are circular structures and are respectively fixed on the turntable.
[0009] Preferably, the rolling body is a spherical structure.
[0010] Preferably, the pneumatic plunger structure includes a cylinder, a piston, and a housing. A spring is fixedly installed between the cylinder and the piston. The piston is slidably connected to the cylinder. The rolling body is rotatably connected to the housing.
[0011] Preferably, a main pipeline is fixedly installed inside the housing. One end of the main pipeline is sealed, and the other end is externally connected to an air pump. A branch pipeline is communicated between each cylinder and the main pipeline, and a solenoid valve is provided on the branch pipeline.
[0012] Preferably, a slideway is fixedly connected inside the housing. A cross plate is slidably installed at the slideway. The main pipeline is fixed relative to the cross plate. An electric push rod is fixedly installed on the slideway. The output end of the electric push rod is fixed to a fixing member on the cross plate.
[0013] Preferably, a strip-shaped static contact is fixedly installed on the cross plate. A moving contact is fixedly installed at the free end of the pneumatic plunger structure. The static contact and the moving contact are electrically connected to the control circuit of the solenoid valve. When the static contact and the moving contact are in contact, the solenoid valve is in the closed state.
[0014] Preferably, a roller for rotation is rotatably installed on the housing, and the roller presses against the elastic layer.
[0015] Preferably, an arc-shaped card slot is provided inside the housing, and the elastic layer is located inside the arc-shaped card slot.
[0016] Preferably, the free end of the telescopic arm is fixedly connected with a connecting rod. A hydraulic cylinder is fixedly installed on the bracket. The output end of the hydraulic cylinder is fixedly connected with the connecting rod.
[0017] Compared with the prior art, the present invention has the following beneficial effects: By adopting a ring-shaped inflatable elastic layer and a pneumatic plunger structure, the rolling body is used to squeeze the elastic layer to form a flexible protrusion. According to the unevenness of the tunnel wall surface, the pneumatic plunger structure automatically adjusts the pressure, squeezes the waterproof board to the sunken area, and automatically stops pressurizing when the appropriate squeezing degree is reached. At the same time, the elastic layer can rotate to adapt to the complex wall surface; intelligent and precise laying is realized, manual operation is reduced, and the laying efficiency of the waterproof board is greatly improved; through the cooperation of the elastic layer and the pneumatic plunger structure, the waterproof board is flexibly squeezed, which not only ensures close fitting but also prevents wear, improves the waterproof quality, and the equipment can adapt to different tunnel profiles and sizes, with strong versatility.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] As Figures 1-8As shown in the figure, an intelligent waterproof board automatic hanging trolley includes a pulley 2 moving along a trolley track 1, a bracket 3, and a winding wheel 4. When the winding wheel 4 moves with the pulley 2, it releases a waterproof board coil 5. A housing 6 is fixedly installed on the telescopic arm of the bracket 3. The free end of the telescopic arm is fixedly connected to a connecting rod. A hydraulic cylinder is fixedly installed on the bracket 3, and the output end of the hydraulic cylinder is fixedly connected to the connecting rod. A main pipeline 12 is fixedly installed inside the housing 6. One end of the main pipeline 12 is sealed, and the other end is externally connected to an air pump. A branch pipeline 13 is connected between each air cylinder 801 and the main pipeline 12, and a solenoid valve 14 is provided on the branch pipeline 13. An elastic layer 7 for rotation is provided inside the housing 6. The elastic layer 7 is of an annular closed structure and is filled with gas inside. A turntable 10 is rotatably installed inside the housing 6. The two ends of the elastic layer 7 are circular structures and are respectively fixed on the turntable 10. A sealed structure is formed between the elastic layer 7 and the turntable 10. An arc-shaped card slot 20 is provided inside the housing 6, and the elastic layer 7 is located inside the arc-shaped card slot 20. A number of pneumatic plunger structures 8 arranged in sequence are also provided inside the housing 6. A rolling body 9 is provided at the free end of the pneumatic plunger structure 8. The rolling body 9 is of a spherical structure. The pneumatic plunger structure 8 includes an air cylinder 801, a piston 802, and a housing 803. A spring 11 is fixedly installed between the air cylinder 801 and the piston 802. The piston 802 is slidably connected to the air cylinder 801. The rolling body 9 is rotatably connected to the housing 803. A slideway 15 is fixedly connected inside the housing 6. A cross plate 16 is slidably installed at the slideway 15. The main pipeline 12 is fixed relative to the cross plate 16. An electric push rod is fixedly installed on the slideway 15, and the output end of the electric push rod is fixed to a fixing part on the cross plate 16. The rolling body 9 squeezes the elastic layer 7 to form a convex structure. A strip-shaped static contact 18 is fixedly installed on the cross plate 16. A moving contact 17 is fixedly installed at the free end of the pneumatic plunger structure 8. The static contact 18 and the moving contact 17 are electrically connected to the control circuit of the solenoid valve 14. When the static contact 18 and the moving contact 17 are in contact, the solenoid valve 14 is in a closed state.
[0028] When the elastic layer 7 moves towards the waterproof board on the tunnel, a surface contact area for the rolling body 9 to move is formed between the two. The pneumatic plunger structure 8 applies a reverse force to the elastic layer 7 through pressurization by the rolling body 9, and squeezes the waterproof board into the sunken area of the tunnel. When the free end of any pneumatic plunger structure 8 moves to the maximum stroke, the pneumatic plunger structure 8 stops pressurizing. A roller 19 for rotation is rotatably installed on the housing 6, and the roller 19 presses on the elastic layer 7.
[0029] During use, the pulley 2 carries the winding wheel 4 and moves along the trolley track 1, driving the support 3 to move synchronously. During the movement, the winding wheel 4 releases the waterproof board coil 5, so that the waterproof board gradually covers the tunnel wall surface. The basic movement logic is the same as that of the traditional hanging trolley, but subsequently, the waterproof board can be attached to the tunnel wall surface. The housing 6 on the telescopic arm of the intelligent support 3 is the core component to achieve intelligent attachment. The elastic layer 7 in the housing 6 is of a circular closed structure, filled with gas inside, and has good elasticity and deformation ability. A number of pneumatic plunger structures 8 arranged in sequence are arranged in the housing 6, and the rolling body 9 at its free end presses the elastic layer 7 to form a convex structure. When the elastic layer 7 moves towards the waterproof board close to the tunnel wall under the drive of the telescopic arm, as Figure 4 shown, a surface contact area is formed between the rolling body 9 and the waterproof board. The air pump supplies air to the main pipeline 12, and the gas enters the air cylinder 801 of the pneumatic plunger structure 8 through the branch pipeline 13. The piston 802 in the air cylinder 801 overcomes the elastic force of the spring 11 under the action of air pressure, pushing the rolling body 9 at the free end to further press the elastic layer 7, causing the elastic layer 7 to produce a greater deformation. At this time, the elastic layer 7 presses the waterproof board into the concave area of the tunnel. By using the flexibility of the elastic layer 7 and the point contact pressure of the rolling body 9, it is avoided that the waterproof board is worn due to excessive local pressure. When the free end of any pneumatic plunger structure 8 moves to the maximum stroke, it means that the concave area of the tunnel at this position has been fully pressed. At this time, the moving contact 17 at the free end contacts the static contact 18 on the cross plate 16, triggering the control circuit, closing the solenoid valve 14 on the corresponding branch pipeline 13, and stopping the air supply and pressurization of the pneumatic plunger structure 8 to prevent over-pressing and damaging the waterproof board. It should be noted that the spring 11 provides a reset force to ensure that the piston 802 returns to the initial position when there is no air pressure. One end of the main pipeline 12 is sealed, and the other end is externally connected to an air pump. The settings of the branch pipeline 13 and the solenoid valve 14 achieve independent air supply control for each pneumatic plunger structure 8. By controlling the opening and closing of the solenoid valve 14, the pressure output of each pneumatic plunger structure 8 can be accurately adjusted to adapt to the depression degree of different positions on the tunnel wall surface.
[0030] Next, the turntable 10 rotatably installed inside the housing 6 is fixed to the circular structures at both ends of the elastic layer 7, and a sealed structure is formed between the two, which enables the elastic layer 7 to rotate with the turntable 10. During the laying process, even if the shape of the tunnel wall surface is complex, the elastic layer 7 can adjust its position by rotating and continuously maintain effective contact with the waterproof board to ensure the continuous progress of the attachment work.
[0031] Next, it should be noted that the slideway 15 inside the housing 6 cooperates with the transverse plate 16, and the electric push rod drives the transverse plate 16 to slide on the slideway 15, thereby adjusting the overall position of the main pipeline 12 and the pneumatic plunger structure 8 to adapt to the changes in the sizes and shapes of different tunnel cross-sections; the roller 19 on the housing 6 presses on the elastic layer 7, and the roller 19 is connected to an external motor, and its rotation is driven by the motor for assisting the rotation of the elastic layer 7; the arc-shaped card slot 20 plays a role in limiting and guiding the elastic layer 7 to ensure that the elastic layer 7 does not shift during the rotation and deformation processes and maintains a normal working state. The free end of the telescopic arm is connected to the hydraulic cylinder on the bracket 3 through a connecting rod, and the telescopic movement of the hydraulic cylinder drives the telescopic arm to move, precisely controlling the distance between the housing 6 and the tunnel wall surface to ensure an appropriate working distance between the elastic layer 7 and the waterproof board.
