Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical engineering field, and specifically relates to a wheel set rotary table. BACKGROUND

[0002] Train wheel sets need to be repaired and then put into use after being used for a period of time, and the wheel sets need to be changed track in the repair process due to the limitation of operation site or the need of production line setting, and the wheel sets need to be turned by 90 degrees during the track changing operation, and it is very difficult to adjust the direction manually due to the large weight of the wheel sets and the positioning on the track, therefore, people design the rotary table for track changing, and it is known that the existing wheel set rotary tables are mostly complex in structure and generally high in price, which is not ideal. SUMMARY

[0003] In order to solve the problems in the prior art, the utility model provides a wheel set rotary table, which is simple in structure, can quickly change the track of the wheel set, and promotes the wheel set to leave the track.

[0004] In order to achieve the above purpose, the technical scheme of the utility model is a wheel set rotary table, which comprises a base, a rotary support rotary table, a rotary table frame, a cylinder positioning device and a wheel pushing assembly.

[0005] The rotary support rotary table is driven to rotate by a motor connected to a speed reducer through gear cooperation.

[0006] The wheel pushing assembly is composed of a cylinder and a push rod, one end of the push rod is arranged on the rotary table frame, and the other end is connected to the end of the piston rod of the cylinder.

[0007] The utility model has the advantages of simple structure, can be installed by using the existing rotary support rotary table, can quickly rotate the wheel set to change the track, the cylinder positioning device can be positioned to ensure that the rotation angle is accurate, and the wheel set can be promoted to leave the track by using the mechanical mode.

[0021] The embodiments of the utility model are described below in combination with the drawings, and it should be understood that the embodiments described herein are only used for explaining and interpreting the utility model, and are not used for limiting the utility model.

[0022] As Figures 1 to 6 shown, the utility model discloses a wheel pair turntable 100, it includes base 1, slewing bearing turntable 2, turntable frame 3, cylinder positioning device 4, push wheel assembly 5, the slewing bearing turntable is established on the base, and the turntable frame is established in the turntable outside with the turntable same plane, the cylinder positioning device is established below the turntable, and the positioning hole 21 is established on the turntable corresponding to the cylinder position, the push wheel assembly is established in the both sides of turntable frame, the below of wheel pair to be pushed,

[0023] The slewing bearing turntable is driven to rotate by motor 22 connecting speed reducer 23 through gear cooperation 24.

[0024] The push wheel assembly is composed of cylinder 51 and push rod 52, and one end of the push rod is arranged on the turntable frame, and the other end is connected to the end of the cylinder piston rod.

[0025] The slewing bearing turntable can be purchased externally, and then the remaining parts are made and assembled to form the wheel pair turntable.

[0026] The utility model is arranged in the pit, and the turntable surface and the turntable frame are flush with the ground, and the longitudinal and horizontal two-way tracks or wheel grooves corresponding to the workshop are arranged on the surface of the turntable and the turntable frame.

[0027] The utility model is controlled by a foot switch.

[0028] The working process of the utility model is as follows:

[0029] As Figure 5 Figure 6As shown, the wheel set enters the center of the wheel set turntable through the workshop track, is started on the wheel set turntable to make it rotate, when 90 degrees, the cylinder positioning device starts, the cylinder piston rod enters the positioning hole to position, the cylinder of the wheel pushing assembly starts, the push rod pushes the wheel set to enter the next working procedure. Then the cylinder positioning device and the wheel pushing assembly are homing, preparing for the next wheel set to enter.

[0030] The above only one of the embodiments of the utility model has been described in detail with reference to the foregoing embodiments, and for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
