Overturning Test System of Catenary Overhaul Vehicle

Abstract

An overturning test system for an overhead contact system maintenance vehicle (1), the system comprising: at least one set of rails (2), a connecting rope (3), a first sensor (41), and at least one second sensor (42); the rail set (2) comprises mutually parallel first rail (21) and second rail (22); the second rail (22) is higher than the first rail (21); one end of the connecting rope (3) is fixedly connected to the supporting arm (12) of the overhead contact system maintenance vehicle (1), and the other end of the connecting rope (3)is fixedly connected to the ground or wall surface of the test ground; the first sensor (41) is disposed on the connecting rope (3), and used to measure tensile force on the connecting rope (3); the second sensors (42) are respectively and fixedly disposed on the rail set (2), and used to measure the pressure on the rails (21, 22) by the wheels of the overhead contact system maintenance vehicle (1). The overturning test system for an overhead contact system maintenance vehicle conducts an overturning test on the overhead contact system maintenance vehicle so as to test whether the anti-overturning performance of the overhead contact system maintenance vehicle satisfies requirements in the operating environment, avoiding an overturning accident in later use, and economic loss.

Description

technical field [0001] The invention relates to a railway vehicle manufacturing technology, in particular to an overturning test system for a catenary maintenance vehicle. Background technique [0002] The catenary maintenance work vehicle is a vehicle used for the maintenance of the catenary in the railway system. [0003] figure 1 It is a schematic diagram of the structure of the catenary maintenance work vehicle, such as figure 1 As shown, the catenary maintenance vehicle includes a car body 10, a wheel set 11, a support arm 12 and a bucket 13; the wheel set 11 is used to drive the car body 10 to walk on the railway track, and the support arm 12 is used to contact the catenary On the electric wire of the car, and move the wire to the side; and the end of the bucket 13 is provided with a working platform, and the bucket 13 can swing in the space above the roof to transport the maintenance personnel and related equipment on the working platform to the convenient The loca...

AI Technical Summary

Problems solved by technology

[0004] Because the suspension bucket 13 on the top of the car body is longer and heavier, it will cause the center of gravity of the car body to deviate to one side when it moves to the laterally extended position, and the support arm 12 will be subjected to the reaction force of the electric wire when the electric wire of the catenary is stirred. It will generate overturning moment on the catenary operation vehicle, which makes the catenary operation vehicle have a greater risk of overturning; especially when the catenary operation vehicle passes through the steel rail with a higher peripheral rail surface, it is easy to overturn, and once it overturns, it will cause huge economic losses
