Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and more specifically, it particularly relates to a device for laying tunnel waterproof materials. Background Technique

[0002] A tunnel is an engineering structure buried in the stratum, which is a form of human utilization of underground space. The structure of a tunnel includes two parts: the main building and the auxiliary equipment. Tunnels that have been in use for a long time are often eroded by rainwater. Therefore, a device for laying waterproof materials is needed to lay the tunnel, so as to extend the service life of the tunnel.

[0003] When some current devices for laying tunnel waterproof materials are laying waterproof materials, they directly wrap the waterproof cloth around the inner wall of the tunnel and then use fixing parts such as bolts to fix the waterproof cloth. However, when fixing the waterproof cloth, the waterproof cloth will fall due to the influence of gravity. At this time, the staff needs to press the waterproof cloth near the fixing position against the inner wall of the tunnel to ensure the fixing effect of the waterproof cloth. This fixing method is time-consuming and laborious, increasing the labor cost. And because the tunnel is usually relatively long, when laying the waterproof cloth, multiple pieces of cloth need to be spliced and fitted together. When the laying device moves, the staff needs to frequently adjust the position of the laying device to ensure that the adjacent two pieces of waterproof cloth can be better fitted together, which affects the work efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a device for laying tunnel waterproof materials is provided, in order to achieve a more practical and valuable purpose. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a device for laying tunnel waterproof materials, which is achieved by the following specific technical means:

[0028] Embodiment:

[0029] As shown in the Figure 1 to the Figure 5 accompanying drawings:

[0030] The present utility model provides a device for laying tunnel waterproof materials, including a machine base 1. A pair of trapezoidal mounting brackets 2 are symmetrically installed at the top end of the machine base 1. A rotating shaft 3 is installed between the pair of trapezoidal mounting brackets 2, and both ends of the rotating shaft 3 respectively penetrate through the opposite sides of the pair of trapezoidal mounting brackets 2 and extend to the outside. Electric telescopic rods 4 are installed at both ends of the rotating shaft 3. A first mounting seat 5 is installed at the top ends of the pair of electric telescopic rods 4. A unwinding roller 6 is installed at the middle position of the top end of the first mounting seat 5. A glue coating roller 7 is installed on one side of the top end of the first mounting seat 5. A pressing assembly is installed on the other side of the top end of the first mounting seat 5. Positioning assemblies are installed at the bottom ends of one side of the pair of trapezoidal mounting brackets 2.

[0031] Among them, the pressing assembly includes a second mounting seat 8. The second mounting seat 8 is installed on one side of the top end of the first mounting seat 5. A first sliding groove 9 is provided at the top end of the second mounting seat 8. A first sliding block 10 is slidably installed inside the first sliding groove 9, and the other end of the first sliding block 10 extends to the outside of the second mounting seat 8. An arc-shaped protrusion is provided at the end of the first sliding block 10 located outside the second mounting seat 8.

[0032] Among them, a first compression spring 11 is installed at the bottom end of the first slider 10, and the other end of the first compression spring 11 is connected to the bottom end of the first chute 9. During the process of the unwinding roller 6 rotating and laying the waterproof cloth on the inner wall surface of the tunnel, the second mounting seat 8 rotates together with the first mounting seat 5. At this time, under the action of the springback of the first compression spring 11, the top end of the first slider 10 always closely adheres to the inner wall surface of the tunnel, squeezing the waterproof cloth, so that the waterproof cloth can be better adhered to the inner wall surface of the tunnel through the adhesive glue applied by the coating roller 7, facilitating the subsequent installation of fasteners or steel bars by the staff.

[0033] Among them, the positioning component includes a third mounting seat 12. The third mounting seat 12 is installed at the bottom end of one side of the trapezoidal mounting frame 2 close to the pressing component. A second chute 13 is provided on the side of the third mounting seat 12 away from the trapezoidal mounting frame 2. A second slider 14 is slidably installed in the second chute 13, and one side of the second slider 14 extends to the outside of the third mounting seat 12. The top end of the second slider 14 has a bevel on the side located outside the third mounting seat 12.

[0034] Among them, a second compression spring 15 is installed on one side of the second slider 14, and the other end of the second compression spring 15 is connected to one side of the second chute 13. When the staff moves the laying device, the second slider 14 always closely adheres to the inner wall surface of the tunnel or the surface of the first waterproof material under the action of the springback of the second compression spring 15. Since the positions of the two second sliders 14 are respectively parallel to the positions at both ends of the unwinding roller 6, the staff can directly judge the unwinding range of the unwinding roller 6 through the positions of the second sliders 14, thereby realizing rapid positioning.

[0035] Among them, a driven bevel gear 16 is installed at the middle position of the rotating shaft 3.

[0036] Among them, a chassis 17 is installed between a pair of trapezoidal mounting frames 2 through a bracket. A motor 18 is installed inside the chassis 17. The output end of the motor 18 is installed with a driving bevel gear 19 through a coupling, and the driving bevel gear 19 and the driven bevel gear 16 are meshed and connected. The motor 18 drives the driving bevel gear 19 to rotate. Since the driving bevel gear 19 and the driven bevel gear 16 are meshed and connected, the driven bevel gear 16 rotates together, thereby driving the rotating shaft 3 to rotate.

[0037] Among them, a steel bar rack 20 is installed on one side of the machine base 1.

[0038] Among them, a plurality of casters 21 are installed at the bottom end of the machine base 1, facilitating the movement of the device.

[0039] Working principle of this embodiment: When using this tunnel waterproof material laying device, the staff first move the device near the starting point of the tunnel and adjust the device to a proper position. Meanwhile, the motor 18 and a pair of electric telescopic rods 4 are turned on. The motor 18 drives the driving bevel gear 19 to rotate. Since the driving bevel gear 19 and the driven bevel gear 16 are meshed and connected, the driven bevel gear 16 rotates together, thereby driving the rotating shaft 3 to rotate. The electric telescopic rod 4 can extend or rotate according to the rotation angle. At this time, the glue applicator roller 7 on one side of the first mounting seat 5 first applies the bonding glue on the inner wall surface of the tunnel. Then, during the movement, the unwinding roller 6 lays the waterproof cloth on the inner wall surface of the tunnel. Finally, the second mounting seat 8 rotates together with the first mounting seat 5. Under the rebounding action of the first compression spring 11, the top end of the first slider 10 always closely adheres to the inner wall surface of the tunnel, causing extrusion on the waterproof cloth, so that the waterproof cloth can be better adhered to the inner wall surface of the tunnel by the bonding glue applied by the glue applicator roller 7, which is convenient for the staff to install fasteners or steel bars subsequently. After the laying is completed, the staff can install the steel bars through the steel bar rack 20. After the installation is completed, the first mounting seat 5 is controlled to reset, and then the laying device is started to move. During the movement, the second slider 14 always closely adheres to the inner wall surface of the tunnel or the surface of the first waterproof material under the rebounding action of the second compression spring 15. Since the positions of the two second sliders 14 are respectively parallel to the positions at both ends of the unwinding roller 6, the staff can directly judge the unwinding range of the unwinding roller 6 through the positions of the second sliders 14, thereby realizing rapid positioning and improving the positioning speed. After the positioning is completed, the staff can repeat the above operations for laying the waterproof material.

[0040] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention so as to design various embodiments with various modifications suitable for specific purposes.
