Abstract

The invention discloses a chain conveyor with a power and free function for a railway vehicle, which is characterized in that the railway vehicle comprises a bogie, the bogie comprises a wheel pair, the wheel pair comprises a wheel flange, the chain conveyor for the wheel pair comprises a track and a conveying chain, and the conveying chain comprises a chain sheet, a pin shaft, a riding wheel and a walking wheel. The chain sheets, the riding wheels and the walking wheels are hinged into a conveying chain through pin shafts; the wheel rims are placed on the riding wheels, and the riding wheels carry the wheel pairs to run through walking of the walking wheels on the rails; when the operation of the wheel pair is hindered, the outer circle of the riding wheel can roll relative to the outer circle of the wheel flange, namely the riding wheel has a power and free function. As the wheel sets are ingeniously placed on the riding wheels which can rotate relatively and are densely arranged, the wheel sets can be stacked behind the stopper one by one and cannot rotate when stopping to move forwards, and the chain conveyor has the main advantages of having the stacking function, and being simple in structure and low in manufacturing cost.

Description

Technical Field

[0001] The invention relates to the technical field of production and maintenance of railway vehicles, in particular to a chain conveyor with accumulation and release functions for railway vehicles. Background Art

[0002] At present, the conveyor lines of railway wheelsets and bogies do not have the accumulation function. Even if a stopper is set in front of each wheelset, the wheelset can only stop on the continuously running conveyor chain, but it is impossible to accumulate the wheelsets one by one. Moreover, the wheelset will inevitably rotate when it stops moving forward, making some operations impossible to implement during this period of time. It can be seen that the main defects of traditional railway wheelset and bogie conveyor lines are: no accumulation function, complex structure, and high manufacturing cost. Summary of the invention

[0003] In view of the problems existing in the prior art, the object of the present invention is to provide a chain conveyor with accumulation and release function for railway vehicles to solve the problems mentioned in the above background technology.

[0005] As a further solution of the present invention: the conveying chain 3 includes an outer traveling wheel chain 31 with traveling wheels 3D located outside the chain plate 3A.

[0006] As a further solution of the present invention: the conveying chain 3 includes an inner traveling wheel chain 32 whose traveling wheel 3D is located inside the chain piece 3A.

[0007] As a further solution of the present invention: the conveying chain 3 includes an asymmetric chain 33, and the outer circle of the support wheel 3C in the asymmetric chain 33 includes an inner boss 3C1; the chain conveyor 2 includes a lifting roller 4 located on the outside of the asymmetric chain 33, and the wheelset 1 is lifted by the lifting roller 4, and the wheelset 1 is separated from the asymmetric chain 33, thereby realizing the rotation of the wheelset 1.

[0008] As a further solution of the present invention: the conveying chain 3 comprises a symmetrical chain 34, the outer circle of the supporting wheel 3C in the symmetrical chain 34 comprises a trapezoidal groove 3C2, and the wheel rim 1A rests on the trapezoidal groove 3C2.

[0009] As a further solution of the present invention: the supporting wheel 3C comprises a smooth wheel 3C3, and the smooth wheel 3C3 and the supporting wheel 3C with an inner boss 3C1 or a trapezoidal groove 3C2 are arranged at intervals in the conveying chain 3.

[0010] As a further solution of the present invention: the chain conveyor 2 includes a stopper 2B, through which the wheel set 1 on the continuously running conveying chain 3 can be stopped from moving forward.

[0011] As a further solution of the present invention: the chain conveyor 2 includes an orthogonal longitudinal low-level conveyor 21, a transverse high-level conveyor 22 and a pulley 5, the longitudinal low-level conveyor 21 includes a fixed high-level rail 2C and a lifting wheel 6, and the transverse high-level conveyor 22 includes a fixed transition rail 2D; through the pulley 5, the wheelset 1 can enter the fixed high-level rail 2C from the transverse high-level conveyor 22 via the fixed transition rail 2D, or enter the transverse high-level conveyor 22 from the fixed high-level rail 2C via the fixed transition rail 2D; through the lifting wheel 6, the wheelset 1 above the lifting wheel 6 can be rotated 90 degrees, that is, the wheelset 1 can be switched between the longitudinal low-level conveyor 21 and the fixed high-level rail 2C.

[0012] As a further solution of the present invention: the track 2A comprises a steel track 2A1, the bottom of the steel track 2A1 comprises a rectangular tube 2A1A, and the conveying chain 3 returning below the chain conveyor 2 runs in the rectangular tube 2A1A.

[0013] In summary, compared with the conventional technology, the present invention ingeniously places the wheelsets on relatively rotatable and densely arranged supporting wheels, which not only enables the wheelsets to be stacked one by one behind the stopper, but also enables the wheelsets to not rotate when they stop and move forward. Therefore, the main advantages of the present invention are: it has the stacking function, simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
