Problems solved by technology

Because the anti-pressure wheel is connected to the horizontal frame of the main beam truss, the deflection force formed by the hoisting gravity at the cantilever end of the horizontal frame on the horizontal frame acts on the track through the anti-pressure wheel, causing the track to receive an upward force. The safety and stability of the track fixed on the corbel poses a threat
In addition, the main girder truss is only anchored by the anti-pressure wheel and the track when it is in contact with the track, and its firmness and stability are poor. Especially when it is not synchronized when walking, the anti-pressure wheel will easily derail and cause the hanging basket to overturn. Therefore, the traditional anti-pressure wheel is used for walking. Device construction safety risk is high
In addition, in the traditional hanging basket walking system, the sliding surface of the main beam truss is in contact with the sliding surface of the track. When the main beam truss has no deflection force, the friction resistance of the sliding surface is very large. When the main beam truss is under the action of deflection force When the horizontal displacement occurs, the sliding surface changes from surface contact to line contact, so that the sliding friction force increases sharply. If the main girder truss needs to be displaced, it must be corrected manually, which is time-consuming and labor-intensive.
[0004] Therefore, the use of the existing hanging basket walking device mainly has the following defects: 1. The structure is too complicated and the weight is heavy; 2. It consumes more materials and wastes costs; It takes 5-6 hours for manpower to rectify the deviation and other cooperation work, and it usually takes 5-6 hours for the 4m long section, which directly affects the construction progress of the bridge upper structure; 4. The existing devices cannot solve the problem of the hanging basket retreating during the walking process

Embodiment 1

[0054] see Figure 1-Figure 4 , a hanging basket with self-locking wheel-rail type walking device, with the same number of hooks as the hanging basket and one-to-one corresponding walking parts, which can realize synchronous walking or independent walking of multiple hooks of the hanging basket to meet different needs. The walking parts include a walking structure 1, a track structure 2, a defense structure 3 and an anti-derailment part 4, and the specific structure is as follows:

[0055] The walking structure 1 includes a power source 1.1 welded on the hook 5 and a rolling boat 1.2 welded to the hook of the hanging basket and driving the rolling boat to walk. Here, the power source 1.1 adopts a motor, which is arranged inside the hook 5 . The rolling boat 1.2 includes a shell 1.21, a roller set 1.22 and a bearing 1.23. The shell 1.21 is a hexahedron structure with an open upper end and a cavity (each face of the hexahedron is connected by welding), and a spacer is arranged ...

Abstract

The invention provides a hanging basket with a self-locking wheel track type running gear; the hanging basket comprises running parts matched in number with and located one by one with hooks of the hanging basket; the running part comprises a running structure, a track structure and a defense structure; the running structure comprise a power source and a roll-boat; the track structure comprises a track single body; the track single body comprises a fixed track and a sawtooth plate; the defense structure is used for preventing the whole roll-boat to go backward. The technical effects are that the whole machine is concise in structure and low in cost; modularization design can be realized by several large parts, so installation, maintenance and replacement are convenient; the running structure, the track structure and the defense structure are combined so as to allow the hanging basket to walk, thus resisting sliding force of the hanging basket in an automatic running process, and preventing the backward effect of the hanging basket in the running or adjusting process; the hanging basket is easy to control and good in stability; the invention also provides a hanging basket running method using said running gear; the method is easy to control and strong in practical values.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a walking device with a self-locking wheel rail for a hanging basket and a walking method for the hanging basket using the device. Background technique [0002] Hanging basket is an important temporary equipment for bridge cantilever construction, suitable for various types of bridges, such as girder bridges, rigid frame bridges, arch bridges, cable-stayed bridges, etc. The hanging basket mainly has two modes in the cantilever pouring construction, that is, the static working mode of the concrete cantilever pouring and the walking and moving mode. Because the construction of the hanging blue cantilever is a segmented construction, after the construction of a certain segment is completed, the track needs to be extended to the next segment to be constructed or turned over and moved forward, and then the hanging basket walks along the track to the front of the poured beam...
