A rock wall beam bridge machine track transport

Abstract

This utility model discloses a track transport tool for a rock face bridge girder machine, comprising a base, symmetrical side plates, L-shaped ear plates, long shafts, pin shafts, bearing I, bearing II, long and short sleeves, and bolts and nuts. The base is fixed to the side plates, with ear plates at the front and rear. Two long shafts pass through the side plates and are locked in place. The long and short sleeves and bearing I are fitted onto the joint of the long shafts to form rolling supports. The pin shaft passes through the ear plates and the bearing II in the middle, and is locked with nut II to achieve swinging or guiding. The number of components can be increased or decreased as needed. The overall structure is symmetrical and the force is balanced. This tool is easy to assemble and can be quickly positioned and installed on a rock face bridge girder machine. The rolling supports reduce friction, and the ear plate-pin connection improves lateral stability, making it suitable for heavy-load track transport and extending the tool's service life.

Description

Technical Field

[0001] This utility model belongs to the field of underground engineering construction technology, specifically relating to a track transport tool for rock wall beam bridge construction. Background Technology

[0002] The underground powerhouse installation bay of the hydropower station is relatively short, and the generator side has a deep foundation pit structure. While the bridge crane rails in the installation bay can be lifted into place using a truck crane, the generator side rails cannot. Conventionally, this section of the rails would be transported using a self-made, ground-mounted trolley. However, the space on the rock face is narrow, and the wheels travel on a concrete surface, resulting in significant resistance. Controlling the trolley's movement is difficult, and over long distances, it is prone to deviation or collision with the already installed rail clamps. This is time-consuming, labor-intensive, and poses a significant safety hazard. Utility Model Content
