Test table capable of simulating lifting rotation operation platform in outer rail ultrahigh working condition of track

Abstract

The invention provides a test table capable of simulating a lifting rotation operation platform in the outer rail ultrahigh working condition of a track. The test table comprises an upper frame and a base frame. The base frame is fixed on the ground. The upper frame is placed on the upper part of the base frame, and front and rear ends of the lower side are hinged with front and rear ends of the upper side of the base frame. Both sides of the upper frame are connected with both sides of the base frame through a buffer telescopic device, so that the upper frame can be tilted with respect to the base frame to simulate the lifting rotation operation platform in the outer rail ultrahigh working condition of the track. According to the invention, through the buffer telescopic device, the upper frame is tilted around a pin, and the lifting rotation operation platform fixed on the upper frame is also tilted to simulate the working condition of the lifting rotation operation platform in the actual work process under the outer rail ultrahigh condition of a curved section; leveling test of a leveling mechanism is carried out to test whether a product leveling mechanism can meet the technical requirement of automatic leveling; various parameters of the lifting rotation operation platform are comprehensively tested to simulate various conditions, so that products can meet delivery requirements; and the work is reliable.

Description

technical field [0001] The invention belongs to the technical field of track engineering experiment devices, and in particular relates to a test bench for a lifting and rotating operation platform capable of simulating the ultra-high working condition of the outer track of the track. Background technique [0002] The lifting and rotating operation platform is an important component of railway construction machinery. It is often used for catenary construction and daily maintenance of catenary. It has high work efficiency, strong mobility, wide application range and high market recognition. The use of the lifting and rotating work platform varies with the situation of the engineering vehicle on the railway line, especially for the faster the speed of the locomotive, and the greater the superelevation of the outer rail on the curved line (currently the maximum superelevation of the outer rail on the curved line is 180mm, and the inclination angle is about 7°). When the outer ra...

Problems solved by technology

However, the existing test bench only plays a fixed role, and cannot truly simulate the working conditions of the super-high outer rail of the track, and cannot test whether the lifting and rotating work platform can be truly leveled under the super-high outer rail, and cannot fully test the lifting and rotating work platform various functions
