Railway engineering vehicle-mounted lifting door device

Abstract

The invention provides a railway engineering vehicle-mounted lifting door device. The lifting door device is characterized in that a first hinge base, a second hinge base, a first safety pin base and a second safety pin base are arranged at the upper end of a door frame, the front end and the rear end of a first lifting hydraulic cylinder are hinged to the first hinge base and the second hinge base together, the front end and the rear end of a second lifting hydraulic cylinder are hinged to shaft heads of the two ends of a cross shaft at the left end of a lifting door together, a third hinge base and a fourth hinge base are arranged at the upper end of the first lifting hydraulic cylinder and the upper end of the second lifting hydraulic cylinder respectively, a fifth hinge base and a sixth hinge base are arranged on the borders of the two sides of the lifting door respectively, the front end and the rear end of a first turning-over hydraulic cylinder are hinged to the third hinge base and the fourth hinge base together, the front end and the rear end of a second turning-over hydraulic cylinder are hinged to the fifth hinge base and the sixth hinge base together, and a first guard railing and a second guard railing are installed on the borders of the two sides of the lifting door respectively. When the vehicle door is closed, safety pins are inserted into a hole in the first safety pin base and a hole in the second safety pin base respectively to lock the lifting door to the door frame of a compartment; an engineering vehicle vehicle-mounted hydraulic system provides power for the hydraulic cylinders in the lifting door device.

Description

Technical field [0001] The present invention involves a car lift door device. Specifically, it is a railway engineering vehicle -carrying door device. Background technique [0002] On the car, there is a high intensity of operation, low work efficiency, and unsafe factors.The existing maintenance and handling method is no longer suitable for the requirements of modern railway construction and railway line maintenance. It is necessary to design a convenient and fast maintenance and handling device to meet the needs of railway engineering vehicle loading and unloading and maintenance. Invention content [0003] The purpose of the present invention is to provide a car -car -carried lifting door device for railway engineering. The vehicle carrier -lift door device has a reasonable design, simple structure, easy to manufacture, and solve the problem of railway engineering vehicle handling and loading. [0004] The technical solution of the present invention is: a railway engineering ...

AI Technical Summary

Problems solved by technology

[0002] At present, the tools used for railway line maintenance are manually carried to the car or from the car to the ground. Some heavy equipment requires several people to be lifted from the car to the line or from the railway line to the ground. On the vehicle, the labor intensity is high, the work efficiency is low, and there
