AI Technical Summary

Technical Problem

Existing rail conveying devices require C-blocks to engage rails from the end, which is time-consuming and labor-intensive. Furthermore, the C-blocks have a fixed size and can only engage rails of a fixed size, resulting in poor compatibility.

Method used

A rail hoisting device was designed, which uses a first clamping component and a second clamping component arranged opposite each other to form a clamping space. A hoisting rope connects the first clamping component to the transport vehicle. The size of the clamping space can be flexibly adjusted to accommodate rails of different widths and can be directly clamped from the side. Combined with components such as a limit ring, limit rod, lifting component and control component, a stable hoisting is achieved.

Benefits of technology

It improves the efficiency and safety of rail hoisting, is compatible with rails of different widths, saves time and labor, reduces labor costs, and improves construction efficiency.

Abstract

The utility model discloses a kind of steel rail hoisting devices, it is related to track construction technical field, including transport vehicle and hoisting assembly, transport vehicle includes frame and the gyroscopically arranged roller in the bottom of frame, hoisting assembly includes first clamping piece, second clamping piece and first sling, second clamping piece is located at transport vehicle, one end of first sling is located at transport vehicle, other end is connected first clamping piece, first clamping piece and second clamping piece are opposite and set and form the clamping space for clamping rail between them. Since first clamping piece is connected to transport vehicle by sling, and the sling is a flexible object, so first clamping piece can approach or move away from second clamping piece by sling, the size of clamping space can be self-adaptively adjusted according to the width of rail, and the clamping hoisting of rail with different width can be compatible. In addition, first clamping piece can be directly clamped from the side of rail, without clamping from the end of rail, save time and effort, and work efficiency is high.
