Retracing type car dumper unloading system with high-position stop device and unloading method

Abstract

According to a retracing type car dumper unloading system with a high-position stop device, the distance from a front car coupler of an open car parked in a manual decoupling device to an open car rear car coupler in a car dumper is A', the distance between two car couplers of a big arm of a car puller is B, the distance from the open car front car coupler in the car dumper to the limit position of the stop device is C', the distance between a front coupler and a rear coupler of the longest open car is D, and the formula that (A'+C'-B)>D is met in terms of arrangement. The unloading method includes the steps that the rear coupler of the car puller is coupled with an open car team; the open car team is pulled to the front coupler of the car puller to be coupled with the open car rear coupler in the car dumper; the open car team is pulled till the coupling point of the second open car and the third open car reaches a manual decoupling position; after a transfer platform returns to a full-load line, decoupling of the second open car and decoupling of the third open car are carried out, the second open car is positioned on the car dumper, the first open car is positioned on the transfer platform, coupling between the car puller and the first open car is removed, and the car puller returns to the manual decoupling position. The retracing type car dumper unloading system with the high-position stop device and the unloading method have the advantages that the open car team finishes traveling the length of one car before the transfer platform returns to the full-load line, and unloading efficiency is improved.

Description

technical field [0001] The invention belongs to the field of an unloading system of a switchback type dumper for a railway gondola car, and in particular relates to the arrangement and an unloading method of a switchback type dumper unloading system with a high-position stopper. Background technique [0002] In the existing turn-back dumper unloading system, in order to prevent the vehicles pushed by the steering machine from falling into the machine pit of the vehicle moving platform when the vehicle moving platform leaves, the towing of heavy vehicles is not started until the vehicle moving platform returns. Due to the limitations of these conditions, the vehicle moving platform often returns slowly, that is, there is a waiting time for the vehicle steering machine during the unloading cycle, resulting in low unloading efficiency. The working process of the current dumper unloading system is: [0003] 1) After the relocation platform returns to the heavy vehicle line, the...

Problems solved by technology

This technology is a high-position stopper. With this high-position stopper, the car unloading system can complete the action before the steering machine is connected with the open car in the dumper in advance, but it cannot make any further actions. If there is any further action, there will be problems due to the absence of the car-moving platform. There is a risk of collision with the car stopper and pushing the gondola car into the car moving pit due to the heavy car line, so it will also delay a lot of time and cause the unloading efficiency to be low
