Abstract

The utility model 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, the conveying chain comprises chain sheets, pin shafts, riding wheels and walking wheels, and the chain sheets are connected with the pin shafts. 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. Due to the fact that 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, the wheel sets cannot rotate when the wheel sets stop moving forwards, and therefore 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] This utility model relates to the field of railway vehicle production and maintenance technology, specifically a chain conveyor with accumulation function for railway vehicles. Background Technology

[0002] Currently, railway wheelset and bogie conveyor lines lack accumulation capabilities. Even with stoppers installed before each wheelset, the wheelsets can only be stopped on the continuously running conveyor chain; they cannot be accumulated one by one. Furthermore, wheelsets inevitably rotate when stopped, making certain operations impossible during this period. Therefore, the main drawbacks of traditional railway wheelset and bogie conveyor lines are: lack of accumulation capability, complex structure, and high manufacturing cost. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a chain conveyor with accumulation function for railway vehicles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A railway vehicle includes a bogie, which includes a wheelset 1. The wheelset 1 includes a wheel flange 1A. A chain conveyor 2 for the wheelset 1 includes a track 2A and a conveyor chain 3. The conveyor chain 3 includes chain segments 3A, pins 3B, rollers 3C, and wheels 3D. The chain segments 3A, rollers 3C, and wheels 3D are hinged together by the pins 3B to form the conveyor chain 3. The wheel flange 1A rests on the rollers 3C. The rollers 3C carry the wheelset 1 through the movement of the wheelset 3D on the track 2A. When the movement of the wheelset 1 is obstructed, the outer circle of the rollers 3C can roll relative to the outer circle of the wheel flange 1A, that is, the chain conveyor 2 has an accumulation function.

[0005] As a further embodiment of this utility model: the conveyor chain 3 includes an outer walking wheel chain 31 with the walking wheel 3D located outside the chain piece 3A.

[0006] As a further embodiment of this utility model: the conveyor chain 3 includes an inner walking wheel chain 32 with the walking wheel 3D located inside the chain piece 3A.

[0007] As a further embodiment of this utility model: the conveyor chain 3 includes an asymmetric chain 33, and the outer circle of the support roller 3C in the asymmetric chain 33 includes an inner boss 3C1; the chain conveyor 2 includes a lifting roller 4 located outside the asymmetric chain 33, which lifts the wheelset 1 and causes the wheelset 1 to disengage from the asymmetric chain 33, thereby realizing the rotation of the wheelset 1.

[0008] As a further embodiment of this utility model: the conveying chain 3 includes a symmetrical chain 34, in which the outer circle of the support roller 3C includes a trapezoidal groove 3C2, and the wheel rim 1A rests on the trapezoidal groove 3C2.

[0009] As a further embodiment of this utility model: the support roller 3C includes a smooth roller 3C3, and the smooth roller 3C3 and the support roller 3C with an inner boss 3C1 or a trapezoidal groove 3C2 are arranged at intervals in the conveyor chain 3.

[0010] As a further embodiment of this utility model: the chain conveyor 2 includes a stopper 2B, which can stop the wheelset 1 on the continuously running conveyor chain 3 from moving forward.

[0011] As a further embodiment of this utility model: the chain conveyor 2 includes an orthogonal longitudinal low-level conveyor 21, a transverse high-level conveyor 22, and a puller 5. The longitudinal low-level conveyor 21 includes a fixed high-level rail 2C and a lifting puller 6. The transverse high-level conveyor 22 includes a fixed transition rail 2D. The puller 5 enables the wheelset 1 to enter the fixed high-level rail 2C from the transverse high-level conveyor 22 via the fixed transition rail 2D, or from the fixed high-level rail 2C via the fixed transition rail 2D. The lifting puller 6 enables the wheelset 1 above the lifting puller 6 to rotate 90 degrees, thereby enabling the wheelset 1 to switch between the longitudinal low-level conveyor 21 and the fixed high-level rail 2C.

[0012] As a further embodiment of this utility model: the track 2A includes a steel track 2A1, the bottom of the steel track 2A1 includes a rectangular tube 2A1A, and the conveyor chain 3 returning from below the chain conveyor 2 runs inside the rectangular tube 2A1A.

[0013] In summary, compared with traditional technologies, this invention cleverly places the wheelsets on support rollers that can rotate relative to each other and are densely arranged. This not only allows the wheelsets to accumulate one after another behind the stop, but also prevents the wheelsets from rotating when stopped and moving forward. Therefore, the main advantages of this invention are: it has an accumulation function, a simple structure, and low cost. Attached Figure Description

The wheel flange 1A rests on the rollers 3C, and the rollers 3C carry the wheelset 1 through the movement of the traveling wheels 3D on the track 2A. When the movement of the wheelset 1 is obstructed, the outer circle of the rollers 3C can roll relative to the outer circle of the wheel flange 1A, that is, the chain conveyor 2 has an accumulation function.

[0030] It should be noted that chain conveyor 2 can also transport railway vehicles or bogies.

[0031] The conveyor chain 3 includes an outer wheel chain 31 with the traveling wheel 3D located outside the chain link 3A.
