Background
At present, the domestic railway crossing type development, the railway line runs busy, passengers and goods run in a mixed mode, high-speed trains of partial lines run in a mixed mode with ordinary trains and the like, and the railway crossing type development is the actual state of the railway in China. If the locomotive cannot run due to faults, the locomotive needs to be rescued, the transportation order is influenced, and in order to minimize the influence, the faulty locomotive needs to be safely driven away as soon as possible, an occupied area is quickly opened, and the influence on the railway transportation order is reduced to the maximum extent.
The bogie driving device is a key part of a locomotive, and mainly comprises a traction motor 4, an axle suspension box 9, a gear box 7, a driving gear, a driven gear and the like. If parts such as wheel set rolling bearings, traction motor bearings and the like have burning loss and fixing faults in the running process, and the wheel set is fixed and cannot rotate, rescue measures must be taken. As shown in fig. 1, the driving device is mainly divided into a rolling axle-suspension type and a frame suspension type according to the installation mode of the traction motor on the bogie. The semi-suspension mode is as follows: one end of the suspension bracket is supported on an axle through two rolling bearings which are respectively arranged in the axle suspension box 9, and the other end of the suspension bracket is suspended on a bogie frame through a motor suspender 6.
In order to solve the problem of the semi-suspended driving device, two types of rescue schemes are summarized at present.
The first type is to use a professional rescue trolley to jack up a fault driving or bogie and lift the wheels off the ground. The failed motor may be removed by the control system of the locomotive or the locomotive may be left inactive and pulled to the service site by another locomotive. The following disadvantages mainly exist:
(1) when the rescue car is used, the running speed of the locomotive is required to be limited, the straight line section of the main line does not exceed 25km/h, the curve section of the main line does not exceed 20km/h, and the speed does not exceed 15km/h when the vehicle passes through a turnout.
(2) The safety risk of the rescue trolley is mainly deformation and damage of the substitute trolley, separation of wheels and the trolley, derailment and the like.
(3) Is only suitable for short-distance rescue.
The second type is a rescue returning disposal scheme adopting a fault position wheel to suspend off the rail surface, and the scheme has high implementation technical requirements, needs guidance of professionals and has a complex implementation process. The suspension of the wheel pair is realized, generally, the axle box spring needs to be taken out or cut off firstly, and then the whole driving device is bound to the framework through the axle box body, the iron chain, the lifting appliance and the like. The following disadvantages mainly exist:
(1) the implementation process of the scheme is complicated, the technical requirement is high, and the guidance of professional personnel is needed;
(2) the long-distance transportation safety risk is high, and the method is only suitable for short-distance rescue;
(3) the running speed of the fault locomotive is limited and cannot exceed the limit of the maximum running speed of 30km/h, and the transportation efficiency of the rescue locomotive cannot be improved.
Therefore, a rescue device and a rescue method for locomotive driving device faults, which can meet the rescue requirements at a longer distance, are sought, the running speed of a faulty locomotive in a transportation project is increased, and the technical problem to be solved by technical personnel in the field is urgently needed.
Based on this, the prior art still remains to be improved.
