Embodiment Construction

[0011] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the sleeper realizes fast clamping of the rail through clamps. When in use, rotate the screw to move the two connecting rods upwards, driving the two jaws of the jaw group to separate to a sufficient distance in the opposite direction, and then place the rail on the sleeper plane to ensure that the distance between the rails meets the requirements, and then reverse Rotate the screw to drive the connecting rod to move down, so that the jaws can grasp the rail to achieve fast clamping and improve efficiency.

[0013] The sleepers of this structure are connected by hinges, the original three-stage structure is integrated into a whole, and a linkage clamping device is used to realize one-time clamping of the rail, which simplifies operation and improves efficiency.

Abstract

Provided is a novel arc-shaped railway sleeper structure of a shield tunneling machine. The novel arc-shaped railway sleeper structure of the shield tunneling machine comprises a screw rod, connecting rods and clamping jaws. The number of the connecting rods is two. The two connecting rods are fixedly connected with the screw rod correspondingly. One end of each connecting rod is connected with the corresponding screw rod, and the other end of each connecting rod is provided with a clamping jaw group. The clamping jaw group comprises two independent clamping jaws. The two clamping jaws are arranged oppositely and connected with the connecting rods through hinges. According to the novel arc-shaped railway sleeper structure of the shield tunneling machine, an original three-section-type structure is connected into a whole through hinge connection, a linkage clamping device is adopted, one-time clamping of a steel rail is achieved, the operation is simplified, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering and relates to a novel arc-shaped sleeper structure of a shield machine. Background technique [0002] The shield machine is a special construction machine for tunneling. During the working process of the shield machine, it needs to move forward continuously. The movement is realized by rolling the wheels of the shield machine on the rails, and the tunnel During the construction process, the segment needs to be continuously transported, and the movement of the segment trolley also requires the laying of steel rails. The rails are laid on curved sleepers specially designed for circular tunnels. The existing arc-shaped sleeper uses a three-stage structure, and the fixing of the rail on the sleeper adopts a structure in which a plurality of briquetting blocks are used to compress the rail, and the actual operation process is also relatively complicated. Contents of the invention [000...
