Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the invention is further introduced:

[0020] Such as Figure 1~2 As shown, a step-by-step self-moving support and lateral movement device of trestle includes guide bracket 2, support cylinder 1, sliding sleeve 3, heightening joint and sliding wear-resistant plate, and support cylinder 1 is installed on the longitudinal direction of guide bracket 2 In the sliding sleeve 3, the traversing oil cylinder 5 is installed on the upper surface of the transverse bracket of the guide bracket 2, and is connected with the traversing rod; One end of the lower part of the sleeve 3 is threaded.

[0021] The further sliding sleeve 3 includes an inner guide sleeve and an outer guide sleeve. The inner guide sleeve is connected with the outer guide sleeve through the support cylinder, and the outer guide sleeve (guide bracket) is lifted and lowered through the expansion and contraction of the support cylinder, and the...

Abstract

The invention discloses a supporting traversing device of a stepping type self-propelled movable trestle bridge. The supporting traversing device comprises a guide bracket, supporting cylinders, sliding sleeves, heightening sections and slide abrasion-resistant plates. The supporting cylinders are mounted on longitudinal sliding sleeves of the guide bracket, and traversing cylinders are mounted on the upper surfaces of transverse brackets of the guide bracket and are connected with traversing draw bars; the slide abrasion-resistant plates are mounted on upper planes of transverse beams of main legs; an end of each heightening section is connected with an end of the lower portion of the corresponding sliding sleeve in a threaded manner. The supporting traversing device has the advantage that the problem of inconvenience in operation due to the fact that supporting legs of the traditional traversing mechanisms are supporting legs without telescopic functions and operation only can be completely carried out by the aid of additional cushion blocks in actual operation procedures can be solved.

Description

technical field [0001] The invention relates to a supporting and laterally moving device, in particular to a supporting and laterally moving device for a step-by-step self-moving trestle, which belongs to the field of construction engineering. Background technique [0002] Inverted arch trestles are widely used in tunnel construction. Before the research of this project, they were basically some traditional simple steel structures that required external force dragging, and some construction companies were modernizing them to make them self-propelled. And other automation functions, but it is basically in the stage of exploration and research, and is gradually being put into use during construction. One of the more successful ones is China Railway No. 5 New and other units, but due to reasons such as price and construction coordination, they have not been widely promoted and used. [0003] The support legs of the traditional traversing mechanism have no telescopic function. ...
