Lifting hoisting frame for railway vehicle installation

Abstract

The invention relates to the technical field of hoisting frames, in particular to a lifting hoisting frame for railway vehicle installation. The lifting hoisting frame comprises bases, supporting seats are welded on the outer walls of the tops of the bases, supporting columns are welded on the outer walls of the tops of the supporting seats, lifting columns are inserted into the top ends of the supporting columns, lifting motors are fixed on the inner walls of the bottoms of the supporting columns through bolts, the output ends of the lifting motors are rotationally connected with screw rods through couplers, and internal thread sleeves located inside the supporting columns are welded to the outer walls of the bottoms of the lifting columns. The lifting hoisting frame has the beneficial effects that the heights of the lifting columns can be adjusted through cooperation of the screw rods and the internal thread sleeves, the lifting columns can be suitable for different lifted objects, and compared with a pure hydraulic cylinder lifting mode, the lifting mode by which the screw rods and the internal thread sleeves are in threaded fit enables the lifting columns to be higher in lifting height and higher in stability; and when guide rods slides inside guide columns, the position deviation of the lifting columns during lifting can be prevented, so that the guide effect on the lifting columns is achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a hoisting frame for rail vehicle installation. Background technique [0002] In the process of installing modern rail vehicles, it is inevitable to encounter some heavy objects that are difficult to carry by manpower. Cranes, hoists and other equipment are needed. Therefore, a lifting frame with excellent performance has become the main facility for lifting and moving objects. [0003] Chinese Patent No. CN203653093U provides a three-stage lift-type lifting frame, which includes a double human-shaped underframe, and the middle part of the double-human shaped underframe is connected with a first-level lifter; the top of the first-level lifter is provided with a sliding support; The middle part of the moving support is provided with a No. 2 mounting seat; the first-level lifter is connected with the lower end of the No. 2 mounting seat through the first-level lifting push ro...

Problems solved by technology

[0005] The purpose of the present invention is to provide a lifting and lifting frame for rail vehicle installation, to solve the problem of using hydraulic cylinders for lifting in multiple places proposed in the background technology. Firstly, using hydraulic cylinders in multiple places increases the cost of the equipment. Low, and the top support arm is a fixed structure, which cannot be adjusted according to the distance between the support arms on the ground, and the length of the support arm is too long to move the hanger very conveniently, and the length is too short to lift large objects.
