Description

Technical Field

[0001] This utility model relates to the field of railway transportation equipment technology, and in particular to a novel migration platform. Background Technology

[0002] The transfer platform in the tippler system is used to move the tipped-over railway vehicles from the loaded track to the empty track. The distance between the loaded track and the empty track is relatively long. Usually, the transfer platform uses a motor reducer to drive pin gears to achieve the translation function. Starting and braking are achieved through frequency conversion control. Precise positioning requires the use of electrical detection elements and wedge-shaped pin devices. The mechanical mechanism is complex and there are many control links.

[0003] In situations where the translation distance is relatively short, there is a need for a device with a simple mechanical structure, low cost, minimal maintenance, and the ability to precisely control position and operate smoothly to achieve the translation function. Summary of the Invention

[0004] The purpose of this invention is to provide a novel migration platform that achieves smooth translation over a relatively short distance using a simpler and more reliable mechanism.

[0005] The function of this utility model is achieved by the following technical solution: a novel migration platform, including a vehicle body, a swing cylinder, a drive arm and a drive rod. The swing cylinder is fixed on the vehicle body, the drive arm is fixed on the swing cylinder and rotates with the swing cylinder, one end of the drive rod is hinged to the drive arm, the drive rod and the drive arm can rotate relative to each other, and the other end of the drive rod is hinged to a fixed wall and can rotate relative to the hinge point.

[0006] When the swing cylinder is at the 0° position, the drive rod and the drive arm form a 0° angle, and the vehicle body is in the initial position. When the swing cylinder drives the drive arm to rotate, the angle between the drive rod and the drive arm increases accordingly, and the vehicle body begins to translate. When the swing cylinder rotates to 180°, the drive rod and the drive arm form a 180° angle, and the vehicle body translates to the end position.

[0007] When the vehicle body is in the starting and ending positions, the three hinge points of the swing cylinder, drive arm, and drive tie rod are all on a straight line, forming dead points. The translation range of the vehicle body cannot exceed the limits at both ends, thus ensuring the translation distance of the vehicle body and achieving the purpose of precise positioning.

[0008] The rotation of the oscillating cylinder is a uniform rotation process, and the translation speed of the vehicle body is related to the rotation speed of the oscillating cylinder by a cosine function. Therefore, the speed of the vehicle body gradually increases and decreases during the starting and stopping process, thus ensuring that there is no impact when the vehicle body starts and stops.

[0009] Compared with existing technologies, this invention has the following advantages: The platform cleverly utilizes the two dead points of the drive arm and drive rod to precisely control the vehicle's displacement. Furthermore, it employs a rotation-to-translation method to achieve slow acceleration at the start of translation and natural deceleration upon reaching the desired position, resulting in shock-free starting and stopping. The platform has a simple structure, using a single mechanical mechanism to achieve precise positioning and smooth operation. It is also low-cost, easy to control, requires minimal maintenance, and occupies little space, making it suitable for use in confined spaces. Attached Figure Description

[0013] Figure 1 , 2 This is a specific embodiment of the present invention. A novel migration platform includes a vehicle body 1, a swing cylinder 2, a drive arm 3, and a drive rod 4. The swing cylinder 2 is fixed on the vehicle body 1, and the drive arm 3 is fixed on the swing cylinder 2 and rotates with the swing cylinder 2. One end of the drive rod 4 is hinged to the drive arm 3, and the drive rod 4 and the drive arm 3 can rotate relative to each other. The other end of the drive rod 4 is hinged to a fixed wall surface and can rotate relative to the hinge point.

[0014] When the swing cylinder is at the 0° position, the drive rod and the drive arm form a 0° angle, and the vehicle body is in the initial position. Figure 1 When the swing cylinder drives the drive arm to rotate, the angle between the drive rod and the drive arm increases accordingly, and the vehicle body begins to translate. When the swing cylinder rotates to 180°, the drive rod and the drive arm form a 180° angle, at which point the vehicle body has translated to the final position. Figure 2 When the vehicle body is in the starting and ending positions, the three hinge points of the swing cylinder, drive arm, and drive tie rod are all on a straight line, forming dead points. The translation range of the vehicle body cannot exceed the limits at both ends, thus ensuring the translation distance of the vehicle body and achieving the purpose of precise positioning.
