[0058] Compared with the prior art, the present invention has the following beneficial effects:

[0059] (1) The tunnel waterproofing cloth hanging trolley provided by the present invention ensures that the tunnel waterproofing construction is fully mechanized through the provision of a honing car, a traveling mechanism, a transverse movement mechanism, a lifting platform and a cloth laying trolley, thereby improving work efficiency.

[0060] (2) The tunnel waterproof cloth hanging trolley provided by the present invention adopts a lifting platform, which is very convenient for personnel to hang cloth. When the lifting platform is raised to the highest position, the operator can smoothly enter the stepped platform. When the cloth laying trolley runs to the other side of the trolley, the lifting platform on the other side is raised to the highest position, and the operator can easily enter the lifting platform on the other side to continue the cloth hanging work. This greatly reduces the time the operator spends on and off the trolley, thereby improving work efficiency.

[0061] (3) The tunnel waterproof cloth hanging trolley provided by the present invention adopts a fixed chain. The chain does not move, and the sprocket moves, making the transmission system reliable and simple, greatly reducing the structural cost of the trolley and greatly reducing the failure rate of the transmission system.

[0062] (4) The tunnel waterproof cloth hanging trolley provided by the present invention has two trolley tracks, which are respectively located at the front and rear ends of the frame, and two cloth laying trolleys with the same structure. Power is transmitted to the two walking boxes by the same main shaft, which ensures good synchronization performance of the two walking boxes.

[0063] (5) In the tunnel waterproof cloth hanging trolley provided by the present invention, the setting of the transverse movement mechanism ensures that it has the function of transverse fine adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0142] The chain 133 enters the box 5011 from the left end, goes around from under the guide sprocket 5015 on the left to above the driving sprocket 5014, and then goes around from above the driving sprocket 5014 to under the guide sprocket 5015 on the right, and enters the chain channel 132.

[0143] The above-mentioned cloth spreading trolley 5 provided by the present invention preferably has the following structure:

[0144] Preferably, there are two travel boxes 501, one mounted on each of the two trolley tracks 13. The main shaft 502 is connected and mounted between the two travel boxes 501. A first connecting crossbeam 505 and a second connecting crossbeam 506 are connected to the front and rear sides of the two travel boxes 501, respectively, fixing the two travel boxes 501 into one body. A worm gear reducer 503 is fixed to the first connecting crossbeam 505. The output end of the motor 504 is fixedly connected to the worm gear reducer 503. The output end of the worm gear reducer 503 is connected to a driving sprocket 5014. Preferably, a power transmission system is formed by a transmission chain and a driven sprocket provided on the main shaft 502. The cloth wheel bracket 507 is hinged on the traveling box 501. The cloth wheel 508 is installed on the cloth wheel bracket 507 and can rotate freely on the cloth wheel bracket 507. The guide wheel bracket 509 is installed on the cloth wheel bracket 507 and is hinged to the cloth wheel bracket 507. The cloth spreading guide wheel 510 is installed at the front end of the guide wheel bracket 509 and can rotate freely. One end of the tension spring 511 is hooked on the guide wheel bracket 509, and the other end is connected to the cloth wheel bracket 507 by a screw rod. This ensures that the cloth spreading guide wheel 510 can always be closely attached to the inner surface of the tunnel when the cloth spreading trolley 5 travels. The adjustment plate 512 is installed on the traveling box 501. The upper end is hinged to the cloth wheel bracket 507, and the lower end is fixed to the U-shaped positioning plate by a pin. By adjusting the adjustment plate 512, the height of the cloth wheel 508 and the cloth spreading guide wheel 510 can be adjusted.

[0145] In the present invention, the housing 5011 is a support for the traveling housing 501. The traveling wheels 5012 are mounted at both ends of the housing 5011 and are rotatable. The clamping wheels 5013 are mounted directly below the traveling wheels 5012 and are rotatable. The driving sprockets 5014 are mounted at both ends of the main shaft 502 and are rotatable under the drive sprocket 5014, serving as the power source for the traveling housing 501. The guide sprockets 5015 are mounted to the left and right of the driving sprocket 5014 and are rotatable. The chain 133 enters the housing 5011 from the left end, passes under the guide sprocket 5015 on the left, passes above the driving sprocket 5014, passes from above the driving sprocket 5014 to under the guide sprocket 5015 on the right, and finally enters the chain channel 132 on the trolley track 13. This is to ensure that the chain 133 has a certain wrap angle on the driving sprocket 5014 to ensure power transmission. It should be noted that the chain 133 mounted on the trolley track 13 is stationary. The power for the movement of the fabric-spreading trolley 5 comes from the main shaft 502, which in turn is powered by the motor 504. The main shaft 502 transmits the power to the driving sprocket 5014. The chain 133 is guided by the front and rear guide sprockets 5015 within the housing. When the driving sprocket 5014 rotates, the power is transmitted to the traveling housing 501, causing the traveling housing 501 to move along the direction of the trolley track 13. When the traveling housing 501 moves forward, the fabric-spreading guide wheel 510 rolls forward along the tunnel surface, pressing the tarpaulin against the tunnel surface and securing it with manual assistance. At the same time, when the fabric-spreading guide wheel 510 rolls forward, it also unfolds the tarpaulin on the cloth wheel 508.

[0146] The power of the two traveling boxes 501 is transmitted by the same main shaft 502, and the driving sprockets 5014 at both ends of the main shaft 502 are the same, so the traveling speeds of the traveling boxes 501 are the same and are completely synchronized.

[0147] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
