Description

Technical Field

[0001] The utility model belongs to the technical field of rail transit, and particularly relates to a wheel set moving device. Background Technique

[0002] The wheel set is the part of a locomotive or vehicle that contacts the rail, and is composed of two left and right wheels firmly pressed on the same axle. The function of the wheel set is to ensure the operation and steering of the locomotive or vehicle on the rail, bear all the static and dynamic loads from the locomotive or vehicle, transfer them to the rail, and transfer the loads generated by the unevenness of the track to each component of the locomotive or vehicle.

[0003] During the process of assembling rail vehicles, the wheel set needs to be moved multiple times to move the wheel set to the corresponding process for processing. For example, during the process of pressing the wheel set bearing, the wheel set needs to be first moved to the pressing place for pressing, and then after the pressing is completed, the wheel pair needs to be moved away. If it is moved manually, there are installation hidden dangers and low efficiency. Content of the Utility Model

[0004] Aiming at the problems of installation hidden dangers and low efficiency when manually moving the wheel set in the prior art, the utility model provides a wheel set moving device.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A wheel set moving device includes a base, a sliding component is arranged on the base, a pushing component is connected to the sliding component, the pushing component includes a mounting frame connected to the sliding component, a fork that can rotate unidirectionally towards the advancing side of the wheel set is arranged on the mounting frame, and a reset mechanism is arranged between the mounting frame and the fork for restoring the fork to the vertical state after rotating unidirectionally towards the advancing side.

[0007] After adopting this technical solution, in this technical solution, by setting a fork that can rotate unidirectionally towards the advancing side of the wheel set, when in use, the wheel set passes through the fork, driving the fork to rotate, so that the wheel set can smoothly pass through the fork, and then the sliding component is started to drive the pushing component to move forward. The fork abuts against the wheel set. Since the fork cannot rotate backward, when the sliding component drives the fork to move, the wheel set can be smoothly driven to move forward, thereby realizing the automatic movement of the wheel set and improving the pressing efficiency.

[0008] Preferably, the base is arranged inside the machine cover, the top of the machine cover is open, and the fork extends out from the top opening of the machine cover.

[0009] After adopting this technical solution, a machine cover is arranged on the base, and the sliding component and the pushing component other than the fork are protected inside the machine cover through the machine cover, which can prevent other instruments from damaging the internal structure of the wheel set moving device, and can also reduce the entry of dust and reduce the failure rate.

[0010] Preferably, the mounting bracket is arranged on one side of the sliding assembly close to the advancing direction of the wheel set. An accordion cover is connected to the side of the mounting bracket away from the advancing direction of the wheel set. The other end of the accordion cover is fixedly connected to the machine cover, and both sides of the accordion cover are slidably connected to the machine cover.

[0011] After adopting this technical solution, the sliding assembly and the main body of the pushing assembly are arranged at the rear side of the fork, and an accordion cover is arranged at the rear side of the fork. The sliding assembly and the pushing assembly are shielded by the accordion cover, further reducing the probability of impurity contamination of the equipment.

[0012] Preferably, the mounting bracket includes a U-shaped bracket connected to the sliding assembly.

[0013] After adopting this technical solution, the fork is limited by the rotating baffle at the rear side of the U-shaped bracket to prevent the fork from rotating backward, so that the fork can drive the wheel set to move.

[0014] Preferably, the reset mechanism includes a torsion spring arranged between the fork and the rotating support shaft.

[0015] After adopting this technical solution, the automatic reset of the fork after rotation is realized through the torsion spring.

[0016] Preferably, a sloping guiding surface is arranged at the end of the fork on the side away from the advancing side of the wheel set.

[0017] After adopting this technical solution, by contacting the wheel set through the sloping guiding surface, the wheel set can smoothly push the fork to rotate.

[0018] Preferably, buffer pads are arranged on both sides of the fork.

[0019] Preferably, the sliding assembly includes an electric slide rail arranged on the base, and the sliding block of the electric slide rail is connected to the pushing assembly.

[0020] After adopting this technical solution, the pushing assembly can be driven to move linearly through the electric slide rail.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0022] 1. In this technical solution, a fork is provided that can rotate unidirectionally towards the advancing side of the wheel set. During use, when the wheel set passes through the fork, it drives the fork to rotate, enabling the wheel set to smoothly pass through the fork.

Since the fork cannot rotate backward, when the sliding component drives the fork to move, it can smoothly drive the wheel set forward, thereby achieving the automatic movement of the wheel set and improving the press-fitting efficiency.

[0023] 2. This technical solution has a compact structure, a small volume, and occupies a small area, and can be used for the movement of various rotatable instruments.

[0024] 3. In this technical solution, a machine cover is provided on the base. The sliding component and the pushing component other than the fork are protected inside the machine cover by the machine cover, which can prevent other instruments from damaging the internal structure of the wheel set moving device and can also reduce the entry of dust and lower the failure rate.

In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0034] The following will be combined with Figures 1 - 4 to make a detailed description of the present utility model.

[0035] Embodiment 1

[0036] As Figures 1 - 4 shown, a wheel set moving device includes a base, a sliding component is arranged on the base, a pushing component is connected to the sliding component. The pushing component includes a mounting frame connected to the sliding component. A fork that can rotate unidirectionally towards the advancing side of the wheel set is arranged on the mounting frame. A reset mechanism is arranged between the mounting frame and the fork 2 for restoring the fork 2 to the vertical state after rotating unidirectionally towards the advancing side.

[0037] In this embodiment, the mounting frame includes a U-shaped frame 7 connected to the sliding component. A rotating baffle 8 perpendicular to the bottom plate of the U-shaped frame 7 is arranged on the side of the U-shaped frame 7 away from the advancing side of the wheel set. A rotating support shaft 6 is arranged on the U-shaped frame 7. The fork 2 is rotatably connected to the rotating support shaft 6. The cooperation of the rotating baffle 8 and the U-shaped frame 7 can enable the fork 2 to rotate within a range of 90 degrees, so that the wheel set can smoothly reach the advancing direction of the fork 2.

[0038] In this embodiment, the reset mechanism includes a torsion spring arranged between the fork 2 and the rotating support shaft 6. The automatic reset of the fork after rotation is achieved through the torsion spring.

[0039] In this embodiment, a slope-shaped guiding surface 3 is provided on the end of the fork on the side away from the advancing side of the wheel set. By contacting the wheel set through the slope-shaped guiding surface, the wheel set can smoothly drive the fork 2 to rotate.

[0040] In this embodiment, as Figure 2 shown, buffer pads 4 are provided on both sides of the fork 2. The buffer pads are made of rubber or silica gel. By directly contacting the wheel set through the buffer pads 4, the collision with the wheel set is reduced, and damage to the wheel set is avoided.

[0041] In this embodiment, the sliding assembly includes an electric slide rail provided on the base, and the sliding block of the electric slide rail is connected to the pushing assembly. The pushing assembly can be driven to move linearly through the electric slide rail.

[0042] The specific usage method of the present utility model is as follows:

[0043] Refer to Figures 1 - 4 , move the wheel set to the position of the fork 2, make the wheel set contact the fork 2, continue to push the wheel set to make the fork 2 rotate. When the fork 2 passes smoothly, the fork 2 returns to its original position under the action of the torsion spring and maintains an upright state. Then start the electric slide rail to drive the fork 2 to move forward through the electric slide rail. Since the rotating baffle 8 restricts the rotation of the fork 2 to the rear side, the fork 2 can smoothly push the wheel set to the required position.

[0044] Embodiment 2

[0045] This embodiment is basically the same as Embodiment 1, except that: the base is arranged in the machine cover 1, the top of the machine cover 1 is open, and the fork 2 extends out from the top opening of the machine cover 1. The machine cover 1 can be made of stainless steel, and its structure is as Figures 1 - 4 shown. The machine cover 1 is arranged on the base. By protecting the sliding assembly and the pushing assembly other than the fork in the machine cover 1, damage to the internal structure of the wheel set moving device by other instruments can be avoided, and the entry of dust can also be reduced, thereby reducing the failure rate.

[0046] Embodiment 3

[0047] This embodiment is basically the same as Embodiment 1, except that: the mounting frame is arranged on the side of the sliding assembly close to the advancing direction of the wheel set, a bellows 5 is connected to the side of the mounting frame away from the advancing direction of the wheel set, the other end of the bellows 5 is fixedly connected to the machine cover 1, and both sides of the bellows 5 are slidably connected to the machine cover 1. The sliding assembly and the main body of the pushing assembly are arranged at the rear side of the fork 2, and the bellows 5 is arranged at the rear side of the fork. By covering the sliding assembly and the pushing assembly with the bellows 5, the probability of impurity contamination of the equipment is further reduced.

[0048] The above-described embodiments merely represent the specific implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all fall within the protection scope of the present application.
