Description

Technical Field

[0001] This utility model relates to the field of railway transportation equipment technology, and in particular to a tippler hook-type car pressing device. Background Technology

[0002] Traditional tippler hook-type pressing devices involve machining a slide rail onto the pressing hook, then mounting a fixed slider on a fixed frame. This requires high parallelism between the slide rail and the slider, and precise control of the gap between them. If the gap is too large, the pressing hook will tilt, causing line contact between the slider and the slide rail, increasing wear and making it prone to jamming or even seizing. If the gap is too small, jamming is even more likely if machining and assembly precision are not up to standard. Therefore, adjusting the gap between the slide rail and the slider is a trade-off process; it's impossible to achieve both. The pressing hook is a large steel structure component, unsuitable for heat treatment, resulting in low slide rail hardness and a significantly reduced service life. Summary of the Invention

[0003] The purpose of this invention is to provide a hook-type pressing device for a tipper, in which the slider can rotate around the rotation axis, ensuring that the slider and the slide rail are always in surface contact, greatly reducing the compressive strength of the contact surface, thereby improving the service life of each component. At the same time, the gap adjustment between the slide rail and the slider becomes less sensitive, greatly reducing the processing accuracy requirements and installation accuracy requirements of each structure, thereby reducing production costs.

[0004] The technical solution of this utility model is implemented as follows: A tipper hook-type car pressing device includes a car pressing hook, a fixed frame, a slide rail, a slider, and a rotating shaft. The fixed frame is installed on a beam, the slide rail is installed on the fixed frame, and the slider is installed on the car pressing hook via the rotating shaft, allowing the slider to rotate around the rotating shaft. This ensures that the slider and the slide rail are always in surface contact, significantly reducing the compressive strength of the contact surface. A car pressing cylinder is connected to the lower part of the car pressing hook, and moves up and down along the slide rail under the drive of the car pressing cylinder.

[0005] Furthermore, a certain gap is left between the slider and the slide rail to prevent the slider from getting stuck when sliding along the slide rail.

[0006] The gap adjustment between the slide rail and the slider becomes less sensitive, and the manufacturing and installation precision requirements of each component are not high. The fixing frame only needs to reach the precision of the riveted and welded parts, which can greatly reduce the processing cost of each component.

[0007] Both sliders and slide rails are small components that can be heat-treated to improve the hardness of the contact surface, significantly extend their service life, and make replacement easier.

[0008] Compared with existing technologies, this utility model has the following advantages: 1. Improved structural stress state, less prone to jamming. 2. Lower manufacturing and equipment precision requirements, resulting in lower processing costs. 3. Smaller size of easily damaged parts, facilitating processing and replacement.
