Detection-type locomotive lifting jack support head with weighing function

Abstract

The invention relates to a detection-type locomotive lifting jack support head with a weighing function, comprising a support head body and a detection bearing device arranged on the support head body. The detection bearing device comprises a connection block, a bearing plate, a spring supporting plate, a spring, a mandril, a load detection limit switch and a weighing sensor. The weighing sensor is mounted on the support head body; the connection block is mounted on the weighing sensor; the bearing plate is arranged above the connection block; the bearing plate is connected with the spring supporting plate on the lower part of the bearing plate; the spring is mounted between the spring supporting plate and the support head body; the lower part of the bearing plate is connected with the mandril through a thread; and the load detection limit switch is mounted on the lateral side of the mandril. The detection-type locomotive lifting jack support head has the detection function. When out of load bearing, the bearing plate is supported by the spring so that a certain gap is formed between the bearing plate and a baffle plate. The initial state of a locomotive is used as the initial point when the whole locomotive is lifted so as to ensure the safety of the locomotive during repair. The invention has the weighing function of the whole locomotive and can save a great amount of money due to no purchase of the weighing device of the whole locomotive.

Description

Technical field [0001] The invention relates to a supporting head part of an underground fixed car crane used for inspection and repair of railway locomotives and rolling stock, in particular to a probe type car crane supporting head with a weighing function. Background technique [0002] After the railway rolling stock has been running for a period of time, the wheelset in the bogie and other parts under the car need to be overhauled or replaced. During maintenance, the entire train of vehicles needs to be raised to a certain height to replace the bogie and other parts at the bottom of the car. When lifting the vehicle body, the original height position of the vehicle cannot be changed to ensure safety. Therefore, the support head is required to stop immediately when the gap between the support head and the backing plate of the body frame is less than 2mm, and then the entire train of vehicles is raised synchronously on this basis. At present, most of the supporting head struct...

Problems solved by technology

Disadvantages of this solution: firstly, the original position of the vehicle is changed after the contact between the support head and the backing plate of the car body frame; second, the adjustment is very inconvenient. When one support head is adjusted, the other support heads are adjusted. The adjusted head load will change again and need to be adjusted repeatedly
