Description

Technical Field

[0001] The utility model relates to a tunnel waterproof board paving device, in particular to a multi-section telescopic waterproof cloth hanging trolley. Background Art

[0002] With economic development, tunnel construction has become increasingly common in our daily lives. During tunnel construction, waterproofing panels are a crucial factor affecting the overall waterproofing effect, and their construction quality is crucial to the overall waterproofing effect. Currently, traditional waterproofing panel installation trolleys are primarily designed for use in arched tunnel sections. These platforms are typically spaced widely apart, requiring a large number of operators to operate simultaneously. However, there are fewer trolleys specifically designed for use in arched, straight-walled tunnel sections.

[0003] Patent document CN202121800390.2 discloses a tunnel waterproofing panel installation trolley structure, which can only meet the needs of one or two similar sections. For multi-section tunnels with large dimensional variations, multiple waterproofing panel trolleys are usually required for laying. This is not only costly, but the frequent replacement of mobile trolleys also greatly increases construction time. Therefore, it is very important to provide a multi-section waterproofing panel trolley structure that is suitable for round arch straight wall tunnel sections and can adapt to large dimensional variations. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the multi-section telescopic waterproof cloth hanging trolley provided by the present invention solves the problem that the waterproof board installation trolley in the prior art cannot achieve the laying of multiple waterproof boards with similar sections, resulting in a long construction time.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is:

[0006] A multi-section telescopic waterproof cloth hanging trolley is provided, which includes a trolley body. Straight wall paving devices are provided on both sides of the trolley body through a lifting mechanism, a top arch paving device is provided on the upper part, and a walking device is provided on the bottom; the two sides of the trolley body are connected to the lifting mechanism through multiple horizontal mechanical telescopic arms, the top arch paving device includes a power part fixed to the top of the trolley body, the output shaft of the power part is fixedly connected to the top arch telescopic arm, and the top arch telescopic arm is rotatably connected to the top arch paving wheel.

[0007] Furthermore, the lifting mechanism includes a support block fixedly connected to multiple horizontal mechanical telescopic arms on the top side of the trolley body, and at least two straight wall rollers fixedly connected to the multiple horizontal mechanical telescopic arms are installed on the lower surface of the support block. A rack meshing with a gear is fixed on the straight wall roller, and one end of the gear axle is connected to the power part, and the other end is movably connected to the straight wall paving device.

[0008] Furthermore, a square frame is provided on the straight wall roller, the wheel axle is located in the square frame, and its two ends are rotatably mounted on the square frame. The end of the square frame away from the gear is rotatably connected to a roller that is in sliding contact with the straight wall roller.

[0009] Furthermore, a supporting platform is fixed to the multiple square frames on at least one side of the trolley body on a side away from the straight wall paving device.

[0010] Furthermore, the straight wall paving device includes a straight wall paving wheel and two connecting arms movably connected to the lifting mechanism. The two ends of the straight wall paving wheel are respectively rotatably connected to a connecting rod. Each connecting rod is respectively installed in the installation cavity of a connecting arm and fixedly connected to a spring fixed at the bottom of the installation cavity.

[0011] Furthermore, the power unit of the top arch paving device is a dual-output motor, and the output shafts at both ends of the dual-output motor are respectively connected to a top arch telescopic arm, and the two top arch telescopic arms are respectively rotatably connected to the two ends of the top arch paving wheel.

[0012] Furthermore, the trolley body includes two support frames and support columns fixed on the top of the two support frames, top plates are fixed on the two support columns, and both support frames are provided with reinforcing supports fixedly connected to the support columns; the walking device is installed on the support frames.

[0013] Furthermore, the support frame includes a plurality of transverse beams and a plurality of longitudinal beams fixed on the plurality of transverse beams, and at least one diagonal brace is connected between adjacent transverse beams and longitudinal beams.

[0014] The beneficial effects of the present invention are as follows: this scheme divides the circular arch straight wall tunnel into two parts, the straight wall and the circular arch, and both the top and the straight wall are paved by machinery, without the need for manual paving. The degree of mechanization is improved, which greatly reduces the work intensity of the construction workers, improves the laying efficiency of the waterproof board, shortens the construction period, and significantly improves the construction efficiency.

[0015] The waterproof board is lifted to the top of the trolley through a lifting device, eliminating the need for workers to climb up and down to carry it, significantly reducing the number of workers and the workload of individual workers, thereby improving work efficiency.

[0016] The horizontal mechanical telescopic arm and the top arch telescopic arm can adjust the overall width and height of the trolley body. In this way, when laying waterproof boards in tunnels with multiple sections, one waterproof hanging trolley can complete the task, reducing the cost of renting or purchasing trolleys, saving time in moving or assembling trolleys, and improving overall construction efficiency.

[0017] The elastic telescopic rod composed of springs, connecting rods and connecting arms in the vertical wall paving device has resilience, which can ensure that the vertical wall paving wheel always sticks to the vertical wall of the tunnel during the rising process, thereby ensuring the laying quality of the waterproof board.

[0018] The trolley body is composed of several crisscrossing horizontal and longitudinal beams, among which reinforcing braces and diagonal braces are interspersed. Through these settings, the strength of the trolley body is significantly improved, thereby ensuring the safety of the operators and greatly reducing the construction risks.

[0025] The specific implementation methods of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific implementation methods. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all utility model creations using the concept of the present invention are protected.

[0026] like Figures 1 to 3As shown, the present invention provides a multi-section telescopic waterproof cloth hanging trolley, comprising a trolley body 1, both sides of the trolley body 1 are provided with straight wall paving devices 3 through a lifting mechanism 2, a top arch paving device 4 is provided on the upper part, and a walking device 5 is provided on the bottom; both sides of the trolley body 1 are connected to the lifting mechanism 2 through multiple horizontal mechanical telescopic arms 6, the top arch paving device 4 includes a power part 41 fixed to the top of the trolley body 1, the output shaft of the power part 41 is fixedly connected to the top arch telescopic arm 42, and the top arch telescopic arm 42 is rotatably connected to the top arch paving wheel 43.

[0027] When in use, first adjust the horizontal mechanical telescopic arm 6 and the top arch telescopic arm 42 according to the width and height of the tunnel section, so that the top arch paving device 4 and the straight wall paving device 3 can contact the top wall and side wall of the tunnel, and then use the lifting mechanism 2 to drive the straight wall paving device 3 to realize the paving of waterproof boards at different heights on the straight wall of the tunnel, and use the power part 41 to drive the top arch telescopic arm 42 to rotate, so as to realize the paving of waterproof boards on different curvatures of the tunnel top arch.

[0028] like Figure 4 As shown, in one embodiment of the present invention, the lifting mechanism 2 includes a support block 21 fixedly connected to multiple horizontal mechanical telescopic arms 6 on the top side of the trolley body 1, and at least two straight wall rollers 22 fixedly connected to the multiple horizontal mechanical telescopic arms 6 are installed on the lower surface of the support block 21. A rack 23 meshing with a gear 24 is fixed on the straight wall roller 22, and one end of the wheel axle 241 of the gear 24 is connected to the power part 41, and the other end is movably connected to the straight wall paving device 3.

[0029] This solution utilizes a gear 24 and rack 23 that work together. When the gear 24 is stationary, the gear engagement provides a locking function, preventing the vertical wall paving device 3 from falling and improving the stability of the vertical wall paving device 3 on the lifting mechanism 2. This structure, which enables lifting operations, has the advantages of simple structure, easy operation, low failure rate, and high durability.

[0030] like Figure 5 As shown, a square frame 25 is provided on the straight wall roller 22, and the wheel shaft 241 is located in the square frame 25, with both ends rotatably mounted on the square frame 25, and the end of the square frame 25 away from the gear 24 is rotatably connected to the roller 26 that is in sliding contact with the straight wall roller 22.

[0031] When the gear 24 moves relative to the rack 23, it can transmit power to the roller 26 through the square frame 25. The roller 26 can ensure the stability of the square frame 25 on the lifting mechanism 2, and at the same time protect the gear 24 to prevent the entire exposed gear 24 from causing a safety accident.

[0032] Reference again Figure 1 and Figure 2A support platform 7 is fixed to the multiple square frames 25 on at least one side of the trolley body 1, on the side away from the vertical wall tiling device 3. The introduction of the support platform 7 allows the transport of tiling materials such as waterproofing sheets to the top of the trolley body 1. At this time, the lifting mechanism 2 can not only move the vertical wall tiling device 3 up and down, but also transport tiling materials.

[0033] The straight wall paving device 3 includes a straight wall paving wheel 31 and two connecting arms 32 movably connected to the lifting mechanism 2. The two ends of the straight wall paving wheel 31 are respectively rotatably connected to a connecting rod 33. Each connecting rod 33 is respectively installed in the installation cavity of a connecting arm 32 and is fixedly connected to the spring fixed at the bottom of the installation cavity.

[0034] The spring, connecting rod 33 and connecting arm 32 can form an elastic telescopic rod with resilience, which can ensure that the straight wall paving wheel 31 always sticks to the straight wall of the tunnel during the rising process, thereby ensuring the laying quality of the waterproof board.

[0035] like Figure 1 As shown, the power unit 41 of the arch paving device 4 is a dual-output motor. The output shafts at both ends of the dual-output motor are respectively connected to a arch telescopic arm 42. The two arch telescopic arms 42 are respectively rotatably connected to the ends of the arch paving wheel 43. Both ends of the arch paving wheel 43 are connected to the arch telescopic arms 42, which can improve the stability during movement.

[0036] The straight wall paving wheel 31 and the top arch paving wheel 43 of this solution have the same structure and are both relatively long, similar to rollers, so that they can cover walls of a larger width during movement to improve paving efficiency.

[0037] like Figure 3 As shown, the trolley body 1 includes two support frames 11 and support columns 12 fixed to the tops of the two support frames 11. A top plate 13 is fixed to the two support columns 12. Both support frames 11 are provided with reinforcing braces 14 fixedly connected to the support columns 12. The walking device 5 is mounted on the support frames 11. The support frames 11 include multiple crossbeams and multiple longitudinal beams fixed to the multiple crossbeams. At least one diagonal brace 15 is connected between adjacent crossbeams and longitudinal beams. The power unit 41 of the top arch paving device 4 is mounted on the top plate 13.

[0038] The top arch telescopic arm 42 and the transverse mechanical telescopic arm 6 of this scheme can both use electric telescopic rods; in order to save production costs, part of the transverse mechanical telescopic arm 6 can also be set as a sleeve and a rod body that slides with the sleeve; it is preferred that the transverse mechanical telescopic arm 6 located on the top side of the trolley body 1 is a sleeve and a rod body. Furthermore, the support column 12 can be set as a hollow structure or the end can be set as a hollow structure to replace the sleeve at the top, and through the cooperation of the support column 12 and the rod body, it serves as the transverse mechanical telescopic arm 6 on the top side of the trolley body 1.

[0039] The trolley body 1 adopts a configuration in which reinforcing braces 14 and diagonal braces 15 are interspersed between the transverse beams and the longitudinal beams, which significantly improves the strength of the trolley body 1, thereby ensuring the safety of the operators and greatly reducing the construction risks.
