Embodiment 1

[0041] Such as Figure 1~9 Among them, there is a trackless trolley for transferring steel mesh panels of rockfill dam panels. A plurality of walking tire devices 5 are provided at the bottom of the trolley frame, and the walking tire devices 5 are connected to the trolley frame through a lifting mechanism;

[0042] A plurality of liftable hooks 9 are also provided at the bottom of the trolley frame. With this structure, the trackless trolley of the present invention can individually adjust the height of the walking tire device 5 and the height of the suspended steel mesh according to the different working conditions of various panel thicknesses in the construction of the panel first and second blocks. To overcome the problems in the prior art.

[0043] In a preferred solution, the lifting mechanism is a screw jack, one end of the screw jack is fixedly connected to the shaft of the walking tire device 5, and the other end of the screw jack is fixedly connected to the trolley frame...

Embodiment 2

[0054] A construction method of a trackless trolley that uses the above-mentioned transfer of steel mesh panels of the rockfill dam faceplate includes the following steps:

[0055] s1. First hoist the first steel truss 1 to the dam surface, adjust the construction direction and fix the position, and then hoist the second steel truss 1'to the dam surface. After adjusting the construction direction, use the hinge pins 13 to connect to each other, and then use The connecting steel member 15 is fixedly connected. The two sides of the trolley frame are connected with the hoist wire rope 14 of the hoist on the top of the dam; the walking tire device 5 is located outside the joint 10 of the current cast block.

[0056] s2. When the walking tire device 5 of the trackless trolley transfers the steel mesh on the post-cast block 12, lift the trolley frame. In the preferred solution, the hydraulic jack in the liftable hook 9 is used to lift the trolley against the ground Or use a car crane to...

Abstract

The invention provides a trackless trolley for transferring reinforcing mesh sheets of rock-fill dam panels and a construction method. A plurality of walking tire devices are arranged at the bottom ofa trolley frame, and the walking tire devices are connected with the trolley frame through a lifting mechanism. A plurality of liftable hooks are further arranged at the bottom of the trolley frame.The construction method comprises the following steps that when the walking tire devices of the trackless trolley transfers the reinforcing mesh sheets on post-poured blocks, through the cooperation of the lifting mechanism and the liftable hooks, the height of the trolley can be adjusted to adapt to a construction site, the liftable hooks hangs the reinforcing mesh sheets, the reinforcing mesh sheets are transported to setting positions by using the trolley, when the arrangement of the reinforcing mesh sheets of a current row is finished, the trackless trolley is moved to another row, and theabove steps are continued; and the transferring of the reinforcing mesh sheets can be realized by above steps. The liftable walking tire devices are arranged, the trackless trolley can be adapted tothe quick hanging and mounting, transferring and quick in-place installation construction of the reinforcing mesh sheets when the panel thickness is varied during the construction of first-poured blocks and the post-poured blocks of the panels.

Description

Technical field [0001] The invention relates to the construction field of face rockfill dams of water conservancy and hydropower, in particular to a trackless trolley for transferring steel mesh of face plates of rockfill dams and a construction method. Background technique [0002] At present, in the 30 years since the concrete face rockfill dam entered China, the construction and installation technology of the face slab reinforcement has been initially developed. The most commonly used method of steel reinforcement production and installation is to use a small steel reinforcement material transport vehicle, which is transported to the binding position by a hoist, and then manually Root handling and binding; another few projects use prefabricated steel mesh, and then use the steel mesh transport trolley to transport the mesh to the installation site. The former method transports bulk steel bars on the slope surface, and the manual transfer installation method on the slope surfac...
