Abstract
The utility model relates to a switch machine, which comprises a motor, a reducer, a gear and rack pair and an actuator rod, wherein the shaft of the motor is connected with the reducer; the output shaft of the reducer is connected with the gear and rack pair; the actuator rod is connected with the gear and rack pair; and the motor is a three-phase AC motor. The switch machine overcomes the disadvantages of the prior switch machine, such as low power, and long switch time. Meanwhile, the switch machine can reduce the failure and improve the work reliability by connecting the three-phase AC motor, the cycloidal pin-wheel reducer, the rack and the actuator rod with each other through connection pins. The switch machine can be used for large and small railway hump marshalling yards, and can reduce the investment cost when newly constructing a railway hump marshalling yard. The switch machine has less maintenance load in comparison with an electropneumatic switch machine, and obviates the maintenance of a compressor for compressing air, a pipe, an air reservoir, a reversing valve, an electropneymatic valve, etc.
Description
Technical field
The utility model relates to a kind of switch machine, especially a kind of switch machine that is applied to railway hump marshalling yard.
Background technology
Switch machine is a kind of equipment that is applied to railway conversion track switch.At the railway automation gravitation marshalling yard, compile the ability of separating in order to improve vehicle, the time of conversion track switch is less than 0.6s, generally adopts electropneumatic switch machine.Then use the time of conversion track switch to be less than the direct current drive switch machine of 0.8s at little ability gravitation marshalling yard.Electropneumatic switch machine self power that uses is little at present, so need corollary equipments such as air compressor station, air pipe line, storage reservoir in the practical application, investment is big, and maintenance workload is big, especially in the winter time, also needs to solve the anti-freezing problem of pipeline and electropneumatic valve.At present the electric switch machine that uses of railway hump marshalling yard is a DC motor, and the motor speed height that the direct current quick acting switch machine is used, and makes the brush high frequency operation of DC motor easily, breaks down easily in the use, and reliability is low.At present be that 0.8s can not satisfy the requirement of transfer time of big automatic gravity marshalling yard track switch the transfer time of the direct current drive switch machine that uses, and promptly requires transfer time less than 0.6s.Because the rail grade of gravitation marshalling yard track switch is brought up to 50kg/m by 43kg/m, the conversion power of track switch all increases, and adds the shortening of transfer time, and the power of motor will increase, present switch machine out of reach requirement.
The utility model content
The utility model provides a kind of interchange quick electric switch machine, has solved the shortcoming in the background technology, has improved the reliability of equipment, has reduced maintenance workload and investment.
Technical solution of the present utility model is: the utility model is a kind of switch machine, comprise electrical motor, retarder, rack-and-pinion, throw rod, described shaft of motor is connected with retarder, the output shaft of described retarder is connected with rack-and-pinion, described throw rod is connected with rack-and-pinion, and its special character is: described electrical motor is a three-phase alternating current motor.
Above-mentioned retarder is the cycloidal-pin wheel retarder.
Above-mentioned retarder is an one-level cycloidal-pin wheel retarder.
Above-mentioned one-level cycloidal-pin wheel retarder comprises cycloidal gear, pin and roll sleeve, and pin is outside equipped with roll sleeve, and roll sleeve contacts with cycloidal gear.
The said gear tooth bar is secondary to be connected by connecting pin with throw rod.
The utility model has overcome the fault of DC motor when high-speed operation with brush owing to adopted the high three-phase alternating current motor of reliability, has strengthened power of electric motor, has satisfied conversion power that strengthens switch machine and the requirement of shortening transfer time.Retarder adopts one-level cycloidal-pin wheel retarder, because the gear that retarder of the prior art uses, its profile of tooth is generally involute, is cliding friction in transmission; And the cycloidal-pin wheel retarder is made up of cycloidal gear, pin and roll sleeve etc., is friction of rolling in the transmission, the driving efficiency height, and it is little to wear and tear, and service life is also long; Tooth bar in the rack-and-pinion is connected with throw rod, and the connecting pin that working strength is bigger replaces the connection mode of past with dissectible pin, has thoroughly eliminated the fault of dissectible pin, has improved the work efficiency of switch machine.
Therefore, the utlity model has following advantage:
1. reliability height: the utility model has reduced fault owing to adopt three-phase alternating current motor, cycloidal-pin wheel retarder, tooth bar to be connected with connecting pin with throw rod.
2. applied range: the utility model can use at large-scale and small-sized railway hump marshalling yard, when the newly built railway gravitation marshalling yard, can reduce investment cost.
3. maintenance workload is little: the utility model is littler than electropneumatic switch machine maintenance workload, and does not need the equipment such as compressor, pipeline, storage reservoir, change-over valve and electropneumatic valve of safeguarding that pressurized air is used.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the scheme drawing of one-level cycloidal-pin wheel retarder of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises electrical motor 1, retarder 2, wherein, the rotating shaft of electrical motor 1 is connected with retarder 2 one ends, the output shaft of retarder 2 is connected with rack-and-pinion 3, throw rod 4 is connected with rack-and-pinion 3 by connecting pin 5, and retarder 2 converts the rotation of electrical motor 1 horizontal balance of throw rod 4 to by rack-and-pinion 3, and switch machine just passes through throw rod 4 and changes track switches like this.
Referring to Fig. 2, retarder 2 of the present utility model adopts one-level cycloidal-pin wheel retarder, and it mainly comprises cycloidal gear 6, pin 7 and roll sleeve 8, and described pin 7 is outside equipped with roll sleeve 8, roll sleeve 8 contacts with cycloidal gear 6, in the retarder running, pin 7 contacts with cycloidal gear 6 by roll sleeve 8, and is rolling touch like this, the driving efficiency height, it is little to wear and tear, and is easy to prolong the service life of pin 7, has reduced fault simultaneously.
