Technical Field

The invention relates to the technical field of subways, also belongs to the technical field of traction motors, and particularly relates to a subway power system with a traction motor.

Background

The subway is a rapid, large-traffic and electric power traction rail transit built in cities. The train runs on a totally closed line, the line located in the central urban area is basically arranged in the underground tunnel, and the line outside the central urban area is generally arranged on a viaduct or the ground. At present, the devices applied to subway stations in the world comprise a subway assembly pump facility, a speed regulator, an explosion-proof mobile substation, a circuit breaker and an additional device, the additional device comprises apparatuses such as a wrench sleeve and the like, a dump truck and a cable drum, and the existing transmission method generally applies the copper cable traction of a winch.

Disclosure of Invention

In order to solve the problems, the invention provides a subway power system with a traction motor, which effectively avoids the defects of the prior art that the dangerous accidents of self-running problem, frequent slipping, deviation, wrong operation of a winch, data transmission error and copper cable breakage increase the probability of injury of an operator and bring adverse effects to reliable maintenance of a subway.

In order to overcome the defects in the prior art, the invention provides a solution for a subway power system with a traction motor, which comprises the following specific steps:

a subway power system having a traction motor, comprising:

a plurality of subway cars 211 connected in sequence; the subway carriage body 211 comprises a driving carriage 2 and a plurality of tractors 3 which are sequentially connected with the driving carriage 2, the tail end of the driving carriage 2 is connected with the head of the driving carriage 2 through a universal joint 4, and the driving carriages 2 are connected through the universal joint 4; the tail end of a tractor 3 at the tail end in the subway carriage 211 is provided with a correcting component 6, the correcting component 6 is connected with one end of a linkage part 5, and the other end of the linkage part 5 is connected with a connecting device 7 at the front end of a driving carriage on another subway carriage.

Further, correction subassembly 6 including link firmly in 3 terminal bottom locating pieces 32 of tractor, vertical link firmly in regulating roller 63 on the bottom locating pieces 32, the rotating is located top locating piece 33 on the regulating roller 63, the regulating roller 63 is in that section on top locating piece 33 is equipped with the worm wheel, still link firmly a plurality of correction motors 62 on the top locating piece 33, the output of correction motor 62 all is equipped with the drive worm wheel, the drive worm wheel interlock worm wheel on the regulating roller 63.

Further, the linkage part 5 is a staggered and curved connecting bar framework, wherein one end of the staggered and curved connecting bar framework is fixedly connected to the top positioning block 33, and the other end of the staggered and curved connecting bar framework is fixedly connected with the connecting device 7; the varicose bars of the staggered varicose joint bar structure are sequentially lowered through the transverse span of one end of the fixing plate 22 towards one end of the joint device 7.

Further, a traction device is arranged on the driving compartment 2, and the traction device is a traction motor.

The universal joints between adjacent carriage bodies in the subway carriage body are connected through plasticity, so that the rail ground surfaces at different heights can be uniformly pressed between the adjacent carriage bodies, and the defects that the subway is separated from the rail and the rail is suspended when running are overcome;

through the linkage portion that sets up between the subway railway carriage or compartment body, can reach the subway and accomplish the performance of turning round operation, and the curved stretch span order of linkage portion reduces, can control the radian that accompanies again and can't be bigger.

And all subway equipment can be straightened into linear conditions through the straightening assembly.

The arrangement of the plurality of subway carriages overcomes the problem of inclined bearing of the common subway and prevents the problems of derailment and suspension of the rail in operation of the common subway; the defect of continuous turning transmission in common subway transmission is overcome; the problem that the subway cannot be completely corrected in the operation process is solved; the performance of subway section componentization disassembly self-operation is achieved.

The invention has the beneficial effects that:

the invention overcomes the problem of inclined bearing of the common subway and prevents the problems of derailment and suspension of the rail in operation of the common subway; the defect of continuous turning transmission in common subway transmission is overcome; the problem that the subway cannot be completely corrected in the operation process is solved; the performance of subway section componentization disassembly self-operation is achieved.
