Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to a lateral translation device for shield machines. Background Art

[0002] Before shield construction, the shield machine needs to be lowered from the ground into the starting shaft and excavated in the direction of the tunnel. However, for some starting shafts, there are diagonal bracing beams for temporary support on the top or underground floor. The shield machine or shield block cannot be directly lowered to the center line of the tunnel. It is necessary to lower the shield machine to the outside of the center line of the tunnel with space for lowering into the shaft. After the shield machine is assembled, the shield machine is moved as a whole parallel to the starting position of the center line of the tunnel.

[0003] At present, the commonly used translation method is to lay a steel plate at the lower end of the bracket bottom plate, apply lubricating oil between the steel plate and the bracket, and use a jack to push the shield machine to move. Due to the large contact surface and sliding friction, the resistance is large, a high-power jack is required, and it is easy to deviate. Utility Model Content

One end of the hydraulic cylinder is hinged to the vertical plate, and the guide shaft slides through the vertical plate.

[0013] The beneficial effects of the present application are as follows: 1. The present application sets rollers and movable troughs. When the shield machine moves, the hydraulic cylinder pushes the bracket to move, thereby driving the shield machine to move. The bracket and the bottom plate have rolling friction. Compared with the prior art, there is sliding friction between the steel plate and the bracket, which has less resistance and is more labor-saving. In addition, by setting movable troughs and guide shafts, the straightness of horizontal and lateral movement is ensured to avoid deviation.

[0014] 2. The first support seat, the support rail, and the second support seat support the first curved plate, which is convenient for the transfer of the shield machine. When the shield machine is transferred to the second curved plate, the spring performs telescopic movement to absorb the impact generated when the shield machine is transferred to the second curved plate. The spring performs telescopic movement for buffering, thereby improving the stress condition of the second curved plate and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS
