Description

Driving wheel rotating wheel system

Technical Field

The utility model relates to the technical field of wheel set overhaul of rail transit vehicles, in particular to a wheel shifting and rotating wheel system.

Background

In the process of overhauling and maintaining the wheel set of the rail transit vehicle, the wheel set needs to be pushed to each station along with the technological process, and corresponding overhauling operation is carried out. The wheel shifting and rotating wheel system can enable the wheel set to finish the movement among the wheel stopping, rotating wheels, front stations and rear stations, and is of great importance in the wheel set maintenance process.

Patent CN201524889U discloses a wheel set shifting device, in which an anti-back stop block and a catch wheel block are connected with a shifting wheel plate for stopping wheels, the shifting wheel plate is connected with a wheel rail frame through a rotating shaft, and a supporting shifting arm on the shifting wheel plate is pushed to rotate, so that the wheel set is discharged.

Patent CN107901702a discloses a wheel set shifting wheel rotating device for rolling stock, in which an anti-back stop block and a positioning stop block are both arranged on a shifting wheel push plate for positioning the wheel set, and the height of a vertical rod is adjusted through an air cylinder so as to adjust the inclination of the shifting plate of the pushing wheel, thereby realizing wheel feeding and wheel discharging.

In the existing thumb wheel rotating wheel system, a stop mechanism is often mounted on a thumb wheel plate, and the mounting structure enables the stop mechanism which is frequently stressed to influence the durability of the thumb wheel plate. When the poking wheel plate is replaced, the stop blocks inserted on the poking wheel plate need to be replaced together, so that the maintenance cost of equipment is increased. When the wheel set is out of the wheel, the stop block fixedly inserted on the poking wheel plate always keeps an extending state, and can impact the wheel set.

The embodiment provides a thumb wheel runner system which is used for overhauling a wheel set 5 of a rail transit vehicle.

As shown in fig. 1, the wheel turning system in the present embodiment includes a wheel rail apparatus 1, a wheel turning apparatus 2, a stopper apparatus 3, and a turning apparatus 4, and in the drawing, an arrow a indicates a traveling direction of a wheel set 5.

Wherein the wheel-rail apparatus 1 is used for providing a track for running the wheel set 5.

In this embodiment, the wheel-rail apparatus 1 is composed of a plurality of plates, and as shown in fig. 5, in the illustrated coordinate system, the X-axis direction indicates the left-right direction and the Y-axis direction indicates the front-rear direction. The left and right sides of the wheel track device 1 are provided with two layers of frame plates 10 which are arranged at intervals. The front side and the rear side of the wheel rail device 1 are respectively provided with a laminate, and the laminate and the frame plate 10 are mutually inserted.

The frame plate 10 has an upper rail surface, two sides of the upper rail surface are linear, and a groove 11 is arranged in the middle. The frame plate 10 is arranged along the travelling direction of the wheel set 5 and plays a role in guiding and supporting the wheel set 5.

The frame plate 10 furthermore provides a mounting location for the wheel rail apparatus 1, the stop means 3 and the wheel means 4.

The stop device 3 is used for stopping the wheel. Wherein the stop device 1 comprises a stop block 31 for stopping the wheel set 5 and a stop block 34 for stopping the wheel set 5, and the stop block 34 and the stop block 31 are sequentially arranged along the travelling direction of the wheel set 5.

As shown in fig. 2, the stop device 3 is connected to the wheel-rail apparatus 1, and in particular, the stop device 3 is disposed on an outer side surface of the wheel-rail apparatus 1. In the thumb wheel rotating wheel system in the embodiment, the stop device 3 is not directly connected with the thumb wheel device, but is arranged outside the wheel rail device 1, so that maintenance personnel can conveniently maintain the wheel rail device.

The stop block 31 is rotatably connected to the wheel rail apparatus 1, and in this embodiment, the stop block 31 is connected to the wheel rail apparatus 1 via a bearing.

As shown in fig. 3, the stopper 31 has a stopper 310 at one end and a stopper weight 311 at the other end. The center of gravity of the stopper 31 is lower than the rotation axis of the stopper 31.

When the stopper 310 passes over the groove 11, the stopper 31 is in a stopped state, and when the stopper 310 is lower than the groove 11, the stopper 31 is in a stored state. The stopper 31 is rotatable between two states. The stopper weight 311 always has a tendency to rotate downward.

One side of the stopper 31 is provided with a stopper fitting 32, and referring to fig. 2, in the present embodiment, the stopper fitting 32 is provided at the lower left of the stopper 31.

When no external force acts, the stop fitting 32 applies resistance to the stop block 31, and keeps the stop block 31 in the first position, and the stop block 31 in the first position is in a stop state. Applying a pushing force to the stopper 31 rotates the stopper 31 by a corresponding angle and maintains the stopper 31 at the second position, and the stopper 31 at the second position is in the accommodated state.

As shown in fig. 3, the stopper fitting 32 is provided with a stopper stay 320.

When the wheel rail device 1 is not subjected to external force, the stop counterweight 311 has a downward movement tendency under the action of gravity and is mutually stopped with the stop support block 320, and the stop part 310 keeps a position beyond the wheel rail device 1 and plays a role of stopping the wheel set 5.

When the external force is removed, the stop weight 311 rotates downward under the action of gravity until falling onto the stop support block 320, and at this time, the stop block 31 is reset and plays a role in stopping.

In this embodiment, the stop support block 320 is made of an elastic material, so as to effectively reduce the collision impact of the stop block 31 during rotation, and facilitate the durability of the stop block 31.

As shown in fig. 2, the retaining block 34 is rotatably connected to the wheel-rail apparatus 1, and in this embodiment, the retaining block 34 is connected to the wheel-rail apparatus 1 via a bearing.

As shown in fig. 4, the retaining block 34 has a retaining portion 340 at one end and a retaining weight portion 341 at the other end. The center of gravity of the stopper 34 is lower than the rotation axis of the stopper 34.

When the retaining portion 340 passes over the groove 11, the retaining block 34 is in a retaining state, and when the retaining portion 340 is lower than the groove 11, the retaining block 34 is in a storage state. The stop block 34 is rotatable between two states. The backstop weight 341 always has a tendency to rotate downward.

One side of the stop block 34 is provided with a stop fitting 35. Referring to fig. 2, in the present embodiment, a stopper fitting 35 is provided at the lower right side of the stopper block 34.

When no external force acts, the retaining fitting 35 applies resistance to the retaining block 34, and holds the retaining block 34 in the third position, and the retaining block 34 in the third position is in the retaining state. When the wheel set 5 advances the wheel and applies pressure to the stop block 34, the stop block 34 rotates by a certain angle and rotates away from the third position.

As shown in fig. 4, the backstop fitting 35 is provided with a backstop block 350.

When the anti-back weight 341 is not subjected to external force, the anti-back weight 341 has a downward movement tendency under the action of gravity and is mutually stopped with the anti-back support block 350, and the anti-back part 340 keeps a position crossing the wheel track device 1, so that the anti-back effect is exerted on the wheel set 5.

When the external force is removed, the weight 340 rotates downward under the action of gravity until it falls onto the backstop block 350, at which point the backstop block 34 is reset and plays a backstop role.

In this embodiment, the retaining support block 350 is made of an elastic material, so as to effectively reduce the collision impact during the rotation of the retaining block 34, which is beneficial to the durability of the retaining block 34.

As shown in fig. 2, the stopping device 3 further includes a first driving member 36 disposed below the rotating bearing of the stopping block 31, where the first driving member 36 is configured to drive the stopping block 31 to rotate, so as to provide a condition for the wheel set 5 to go out of the wheel. In this embodiment, the first driving member 36 is a pneumatic push rod.

It is conceivable that in this embodiment the rotational bearing of the stop 31 is provided with a support arm.

Wherein the pneumatic push rod extends upwards to push the support arm to rotate, so that the stop block 31 rotates to the second position, and the stop wheel pair 5 is not stopped any more. The pneumatic push rod is retracted downwardly and the stop block 31 is rotated to the first position under self-gravity.

The stop means 3 further comprise a position sensor 33 for determining the position of the stop block 31.

Referring to fig. 2, two position sensors are provided in the present embodiment, and one position sensor is provided outside the stopper weight portion 311 of the stopper block 31 in the first position for detecting whether the stopper block 31 is in the first position. The outer side of the stopper weight 311 of the stopper 31 at the second position is provided with another position sensor for detecting whether the stopper 31 is at the second position.

When the wheel set 5 is out of the wheel, the first driving piece 36 drives the stop block 31 to rotate to the second position, and after the position sensor 33 detects and determines that the stop block 31 is in place, the wheel-pulling wheel rotating wheel system performs the wheel-out operation.

The wheel-shifting device 2 is used for lifting the wheel set 5 after stopping the descent or lifting. Wherein the transmission mechanism 21 drives the wheel plate 20 to rotate, so that the wheel set 5 descends or ascends.

As shown in fig. 6, the click plate 20 is provided between two layers of the shelf plates 10, and the two layers of the shelf plates 10 play a role of guiding the click plate 20 for preventing the click plate 20 from being deviated.

Referring to fig. 5, the dial plate 20 is provided with a pad 23 on both sides, and the pad 23 is used to adjust the gap between the dial plate 20 and the frame plate 10.

The first end of the dial plate 20 is rotatably connected to any one of the frame plates 10, as shown in fig. 3, and in this embodiment, the first end is rotatably connected to the outer frame plate 10. The second end of the pinion plate 20 is slidably connected to a transmission 21.

The paddle 20 is located in the recess 11. Referring to fig. 3, the wheel set 20 is shown in an initial position in which the wheel set 5 may smoothly travel from the frame plate 10 onto the wheel set 20. When stopping the wheel, the wheel set 5 falls onto the plectrum 20.

The transmission mechanism 21 is arranged on the side of the inner layer frame plate 10, which is away from the outer layer frame plate 10, and the transmission mechanism 21 is used for driving the wheel shifting plate 20 to rotate.

The transmission mechanism 21 is arranged inside the wheel rail device 1, so that the space occupied by the wheel shifting and rotating wheel system is reduced.

When the transmission mechanism 21 drives the wheel shifting plate 20 to rotate downwards by a corresponding angle, the wheel set 5 descends along with the wheel set, and therefore falls onto the rotating wheel device 4; when the transmission mechanism 21 drives the dial plate 20 to rotate upwards by a corresponding angle, the wheel set 5 rises along with the dial plate and goes out of the wheel along the inclined dial plate 20.

The second end of the dial plate 20 is provided with a sliding groove 201, and referring to fig. 3, one end of the first link 211 is slidably connected in the sliding groove 201. When the first link 211 rotates, the second end of the pinion plate 20 is pushed to rotate around the first end.

The shelf 10 is provided with a movable hole for providing a rotation space for the first link 211.

Referring to fig. 6, the other end of the first link 211 is connected to a transmission shaft 212, the transmission shaft 212 is connected to a second link 213, and the second link 213 is rotatably connected to the second driving member 22.

With continued reference to fig. 6, the wheel-rail apparatus 1 further includes fixing members 12, the fixing members 12 are connected to the bottom of the wheel-rail apparatus 1, two ends of the transmission shaft 212 are connected to one of the fixing members 12, and the two fixing members 12 restrict the rotation of the transmission shaft 212 about its axis.

In this embodiment, the first link 211, the second link 213, and the transmission shaft 212 can be rotated synchronously about the axis of the transmission shaft 212.

As shown in fig. 6, the transmission shaft 212 is disposed at the bottom of the transmission mechanism 21, and the second link 213 is connected to the second driving member 22 obliquely upward. In this embodiment, the driving members in the driving mechanism 21 are not sequentially arranged along the height direction, so that the height of the driving mechanism 21 is effectively reduced, and the dial wheel and runner system is more compact.

In this embodiment, the second driving member 22 is a hydraulic push rod.

As shown in fig. 6, when the hydraulic push rod is extended, the second link 213 is pushed to rotate counterclockwise, the transmission shaft 212 and the first link 211 rotate counterclockwise synchronously, and the first link 211 drives the second end of the pinion plate 20 to rotate downward.

When the hydraulic push rod is shortened, the second connecting rod 213 is pulled to rotate clockwise, the transmission rotating shaft 212 and the first connecting rod 211 synchronously rotate clockwise, and the first connecting rod 211 drives the second end of the pulley plate 20 to rotate upwards.

The thumbwheel device 2 also includes a wheel set sensor 24. As shown in FIG. 5, the wheel set sensor 24 is coupled to the wheel track device 1. After the wheel is discharged, the wheel set sensor 24 detects that the wheel set 5 leaves the station, and the wheel shifting plate 20 and the stop block 31 are reset.

The turning wheel device 4 is used for turning the driving wheel pair 5.

As shown in fig. 7, the wheel assembly 4 includes a driving wheel 41 and a driven wheel 42, and the driving wheel 41 and the driven wheel 42 are rotatably connected to the inner side surface of the wheel track assembly 1.

The driving wheel 41 and the driven wheel 42 are arranged below the groove 11, and both have a part of the wheel body passing over the groove 11.

When the dial plate 20 rotates downwards, the wheel set 5 gradually descends and falls on the driving wheel 41 and the driven wheel 42, the driving wheel 41 drives the wheel set 5 to rotate, and the driven wheel 42 assists the wheel set 5 to rotate.

In this embodiment, the rotary apparatus 4 is driven by a hydraulic motor.

The dial wheel and runner system in the embodiment realizes the linkage of all devices through instruction control, and comprises a dial wheel instruction and a runner instruction. The instruction is issued through the console.

The operating principle of the thumb wheel runner system in this embodiment is as follows:

when the wheel set 5 travels, the wheel set 5 contacts and presses the stop block 34, the wheel set 5 continues to travel, contacts the stop block 31 and stops, and the stop block 34 resets under self gravity and stops the wheel set 5, so that the wheel set 5 stops between the stop block 31 and the stop block 34 and stops on the thumb wheel plate 20.

After stopping the wheel, the control console sends out a wheel turning instruction, and the wheel shifting device 2 and the wheel turning device 4 are linked to realize the wheel turning. Wherein, the dial wheel plate 20 rotates downwards under the drive of the transmission mechanism 21, and the wheel set 5 descends and falls on the driving wheel 41 and the driven wheel 42. The driving runner 41 drives the wheel pair 5 to rotate, and the driven runner 42 assists the wheel pair 5 to rotate, thereby realizing a runner.

After the operation is finished, the control console sends out a wheel shifting instruction, and the stop device 3, the rotating wheel device 4 and the wheel shifting device 2 are linked to realize wheel discharging. Wherein the stop block 31 is rotated to the second position under the drive of the first drive member 36 and no longer acts as a stop for the wheel set 5. The active wheel 41 stops the wheel. After the position sensor 33 detects that the stop block 31 rotates to the second position, the wheel shifting plate 20 is driven by the transmission mechanism 21 to rotate upwards, the wheel set 5 rises along with the wheel shifting plate 20 to take out wheels, the wheel set 5 converts gravitational potential energy into kinetic energy, the wheel set travels forwards, and the speed of the wheel set 5 travelling to the upper rail surface depends on the lifting height of the wheel shifting plate 20.

After the sensor 24 of the wheel set 5 detects that the wheel set 5 leaves the station, the stop device 3 and the thumb wheel device 2 are reset. The thumbwheel runner system waits for the next wheel set 5 to enter.
