Fixed train lifting overhauling device with complete train weighing function

Abstract

The invention relates to rolling stock repair equipment, in particular to a fixed train lifting overhauling device with a complete train weighing function. The fixed train lifting overhauling device mainly comprises a bogie lifting mechanism, a train body lifting mechanism, steel structure carrying platforms and weighing unit modules. By the adoption of the overhauling device, an complete train can be lifted through the bogie lifting mechanism and the train body lifting mechanism under the condition that the complete train is not disassembled, any bogie of the train can be disassembled and replaced, electrical facilities on the lower portion of a train body can be overhauled and replaced, the axle weight, the bogie weight, the complete train weight, the side edge weight, the single wheel weight average value and the complete train gravity plane coordinates of the train can be measured under the condition that the station is not changed, and therefore the operations such as train lifting and spring adjustment can be further conducted on the same station.

Description

Technical field [0001] The invention relates to a railway locomotive and rolling stock maintenance equipment, in particular to a fixed frame car maintenance device with a complete vehicle weighing function. Background technique [0002] In order to realize the safety and comfort of vehicle operation, the rolling stock depot usually needs to detect the wheel weight, axle weight and weight of the vehicle before and after vehicle maintenance. [0003] The most complete and convenient equipment for vehicle maintenance is the pit (fixed) type vehicle crane. The pit crane is used for the maintenance of the entire train without disintegration of the rolling stock, including the replacement of the vehicle bogie, the maintenance and replacement of the electrical facilities under the car body and the electrical facilities on the roof, etc. Chinese patent number CN102718172 discloses a compatible pit-type car body lifting unit. When the lifting unit is used for lifting the car, the bogie lif...

Problems solved by technology

Chinese Patent No. CN02213974.5 discloses a static locomotive and rolling stock weighing platform. The test platform has a T-shaped slot adjustment platform, lead rails on the left and right sides, and structural modules such as weighing units. Through the above mechanisms and software systems Realize the weighing function of the vehicle, but the device cannot carry out the lifting operation on the vehicle

This weighing method requires the vehicle to be lifted before weighing, and there are only two sensors at both ends of the weighing device, which does not consider the influence of the unbalanced load at the other two ends, which seriously affects the weighing accuracy

[0006] It can be seen that the current vehicle erection repair and weighing inspection are at different stations. Every time the vehicle is weighed, it needs to be towed to the erection station for repair by towing the vehicle. After the maintenance is completed, the vehicle needs to be towed again. The weighing station performs rechecking and weighing, the work process is complicated, and the equipment occupies a large amount of work space, which brings inconvenience to the maintenance of the vehicle, and the construction cost is also high
