Description

Technical Field

[0001] This utility model relates to the field of track technology, specifically to a track pressure plate structure that prevents loosening. Background Technology

[0002] In the field of track technology, track clamps, as core components connecting the track and the foundation structure, directly affect the safe operation of the track system. However, existing track clamp structures have significant defects: Firstly, traditional clamps often rely on a single bolt for fixation. In long-term vibration environments (such as in rail transit and industrial conveyor rail operation), the bolt is prone to loosening due to vibration, leading to a decrease in the fit between the clamp and the guide rail, and even causing track displacement, posing safety hazards. Secondly, some clamps lack effective buffering and anti-slip structures, failing to mitigate the impact of track vibration on the connection points, and the insufficient friction of the contact surface further exacerbates the risk of loosening. In addition, the materials and anti-corrosion treatments of existing clamps and fasteners have poor compatibility, making them prone to corrosion and strength reduction under complex working conditions such as humidity and dust, shortening their service life and failing to meet the requirements for long-term stable operation of the track system.

[0003] To address this issue, we propose a track pressure plate structure that prevents loosening. Utility Model Content

[0004] The purpose of this invention is to provide a track pressure plate structure that prevents loosening, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a track pressure plate structure for preventing loosening, comprising a pressure plate and a guide rail, the guide rail being vertically fixedly disposed on the top surface of the pressure plate, a triangular plate being fixedly installed on the side of the guide rail, an upper wedge plate and a lower wedge plate being respectively contacted on the inclined surface of the triangular plate, the upper wedge plate and the lower wedge plate being fixedly installed by bolts.

[0006] Preferably, the top surface of the four corners of the pressure plate has fixing holes.

[0007] Preferably, the bolts are made of high-strength, corrosion-resistant alloy material.

[0008] Preferably, the pressure plate is made of Q355 high-strength steel plate and is hot-dip galvanized for corrosion protection.

[0009] Preferably, a buffer pad is provided between the upper wedge plate and the lower wedge plate, with the top surface of the buffer pad fixedly installed to the bottom surface of the upper wedge plate, and the bottom surface of the buffer pad fixedly installed to the top surface of the lower wedge plate.

[0010] Preferably, the buffer pad is made of nitrile rubber with a thickness of 2-5mm and has a textured surface for anti-slip purposes, which is used to buffer track vibration and enhance the friction between the pressure plate and the guide rail.

[0011] Preferably, a buffer ring is provided between the upper end of the bolt and the upper wedge plate. The buffer ring is an elastic metal washer with a wave structure design, which has axial elastic compensation capability, can offset the loosening gap of the bolt, and maintain the stability of the preload.

[0012] This utility model provides a track pressure plate structure to prevent loosening. This track pressure plate structure has the following advantages:

[0013] This anti-loosening track pressure plate structure effectively avoids loosening problems under long-term vibration environment through multiple anti-loosening designs: the triangular plate and wedge plate form a mechanical self-locking mechanism, the buffer pad enhances the friction of the contact surface and buffers vibration, and the buffer ring compensates for the bolt gap to stabilize the preload; at the same time, the high strength and corrosion-resistant design of the pressure plate and bolts ensures the long-term durability of the structure, and the overall track connection achieves stability and reliability.

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] A preferred embodiment of the anti-loosening track pressure plate structure provided by this utility model is, for example... Figures 1 to 4As shown: A track pressure plate structure for preventing loosening includes a pressure plate 1 and a guide rail 3. The pressure plate 1 has fixing holes 2 on its top surface at each of its four corners. The pressure plate 1 is made of Q355 high-strength steel plate and is hot-dip galvanized for corrosion protection. The guide rail 3 is vertically fixed to the top surface of the pressure plate 1. A triangular plate 7 is fixedly installed on the side of the guide rail 3. An upper wedge plate 4 and a lower wedge plate 5 are respectively positioned on the inclined surfaces of the triangular plate 7. The upper wedge plate 4 and the lower wedge plate 5 are fixedly installed together by bolts 6. The bolts 6 are made of high-strength, corrosion-resistant alloy material. The upper end of the bolt 6 is connected to the upper... A buffer ring 9 is provided between the wedge plates 4. The buffer ring 9 is an elastic metal washer with a wave structure design and has axial elastic compensation capability. It can offset the loosening gap of the bolt 6 and maintain the stability of the preload. A buffer pad 8 is provided between the upper wedge plate 4 and the lower wedge plate 5. The top surface of the buffer pad 8 is fixedly installed with the bottom surface of the upper wedge plate 4, and the bottom surface of the buffer pad 8 is fixedly installed with the top surface of the lower wedge plate 5. The buffer pad 8 is made of nitrile rubber with a thickness of 2-5mm. The surface is provided with concave and convex anti-slip texture to buffer the vibration of the track and enhance the friction between the pressure plate 1 and the guide rail 3.

[0021] Working principle: The overall installation and positioning are achieved through the fixing holes 2 at the four corners of the pressure plate 1. After the guide rail 3 is vertically fixed to the top surface of the pressure plate 1, the triangular plate 7 on its side provides an inclined support surface, so that the upper wedge plate 4 and the lower wedge plate 5 form a self-locking structure by fitting together through the inclined surface. With the nitrile rubber buffer pad 8 with a thickness of 2-5mm and a textured surface for anti-slip, it not only buffers the vibration of the track but also enhances the friction of the contact surface. The bolt 6 is made of high-strength corrosion-resistant alloy material and passes through the upper wedge plate 4 and the lower wedge plate 5 to complete the fixation. The wave-shaped elastic metal buffer ring 9 between its upper end and the upper wedge plate 4 provides axial elastic compensation, offsetting the bolt loosening gap within 0.1mm to maintain the stability of the preload. At the same time, the pressure plate 1 is made of Q355 high-strength steel plate, stamped and formed and hot-dip galvanized for corrosion protection. The overall structure achieves the anti-loosening effect under long-term vibration environment through the multiple synergies of mechanical self-locking, elastic compensation and friction enhancement.
