This utility model relates to tunnel engineering equipment, particularly a tunnel Waterproof Board Hanging Cart Currently, waterproofing membranes must be installed inside tunnels during tunnel construction. At present, this installation is performed manually from scaffolding, which is inefficient and labor-intensive. Therefore, the development of a new type of suspended trolley for tunnel waterproofing panels is an urgent issue that needs to be addressed.

　　This utility model provides a tunnel. Waterproof Board Hanging Cart which can effectively improve labor efficiency and reduce labor intensity. The present invention relates to a tunnel waterproofing board hanging trolley, comprising a trolley body that includes sliding wheels, a main support frame, and two arch-shaped supports; the sliding wheels are mounted at the bottom of the main support frame and are configured to drive the main support frame along guide rails; the two arch-shaped supports are mirror-mounted at the front and rear ends of the main support frame, with shapes that match the cross-section of the tunnel, and each arch-shaped support comprises two parallel transmission chains; two pulley sets are mirror-mounted on the two transmission chains, with each pulley set including pulleys, hydraulic motors, reduction gear assemblies, and hollow support sleeves; the pulleys cooperate with the transmission chains and, under the action of the reduction gear assembly, can move along the chains; the hollow support sleeves are fixedly mounted on the pulleys, with their longitudinal direction perpendicular to the direction of pulley movement; two pressing rod drive assemblies are mirror-mounted on the two trolleys, each comprising V-shaped guide posts, a first hydraulic cylinder, a second hydraulic cylinder, a rocker arm, and a pressing rod; one end of the V-shaped guide post is fitted inside the hollow support sleeve and is slidably connected to it; the two ends of the first hydraulic cylinder of the waterproofing board hanging trolley are respectively fixed to the V-shaped guide post and the hollow support sleeve, thereby controlling the sliding of one end of the V-shaped guide post within the hollow support sleeve; one end of the rocker arm of the waterproofing board hanging trolley is rotatably connected to the V-shaped guide post, while the pressing rod is positioned at the other end of the rocker arm, and the second hydraulic cylinder is used to control the rotation of the rocker arm about one end; the basket of the waterproofing board hanging trolley is suspended between the two V-shaped guide posts. It comprises a basket body and lifting lugs provided on both sides of the basket body, with the basket body suspended between the two V-shaped guide posts via these lugs. The waterproofing board hanging trolley is provided with a groove on the central plane away from the two ends of the V-shaped guide posts, and one end of the rocker arm is positioned within this groove. The two ends of the second hydraulic cylinder are respectively rotatably connected to the other end of the rocker arm and the other end of the V-shaped guide post. The tunnel waterproofing board hanging trolley also includes a roll-up roller positioned between the other ends of the V-shaped guide posts.

　　The advantages of this utility model are: through the tunnel Waterproof Board Hanging Cart The first hydraulic cylinder controls the sliding of one end of the V-shaped guide post along the hollow support sleeve, while the second hydraulic cylinder causes the rocker arm to pivot about one end, enabling the waterproof membrane suspended from the pressing rod to be pressed firmly against the tunnel lining. At this point, personnel working in the suspended platform can conveniently and quickly secure the waterproof membrane to the tunnel lining, thereby efficiently installing the membrane and effectively reducing the labor intensity of the installation process.
