Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to an arc-shaped pressure chain plate for the tail of a scraper conveyor. Background Art

[0002] In the operation of the fully mechanized mining face in coal mines, the scraper conveyor plays a vital role and is responsible for the continuous transportation of coal. However, in actual use, in order to increase the installation space of the components, the tail part of the machine is often designed as a raised structure. This design causes the running trajectory of the scraper chain at the tail to change from the original downward oblique running to horizontal running. This change in angle makes the wear problem between the scraper at the tail position and the arc-shaped pressure chain plate particularly prominent. Specifically, the inclined surfaces at both ends of the scraper are in contact with the arc-shaped pressure chain plate. During long-term operation, due to continuous friction, the arc-shaped pressure chain plate will show significant wear. Unfortunately, the wear resistance of traditional arc-shaped pressure chain plates is often difficult to meet the requirements of long-term and high-intensity operation, so their service life is relatively short, which undoubtedly increases the maintenance cost and downtime of the equipment and affects the production efficiency of coal mines.

[0003] Although the arc-shaped pressure chain plate disclosed in Chinese patent CN204642943U solves some problems to a certain extent, it still seems to be powerless when facing complex factors such as load changes and equipment vibration during the operation of the scraper conveyor. These factors will cause the gap between the pressure chain plate and the scraper to change dynamically, and the original design lacks an effective adaptive adjustment mechanism to maintain the optimal contact state between the two in real time. This deficiency not only exacerbates the wear problem, but may also have an adverse effect on the overall performance and stability of the scraper conveyor. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0016] like Figure 1 to Figure 2As shown, an arc-shaped chain-pressing plate for the tail of a scraper conveyor is installed on the telescopic slot 1 at the tail of the scraper conveyor, which cleverly adapts to the working environment and requirements of the conveyor. The telescopic slot is connected to a bottom plate 2, including a sliding plate 31, and the sliding plate is connected to an upper pressure plate 35, so that the upper pressure plate can apply pressure smoothly and accurately. The bottom of the upper pressure plate is connected to a side pressure plate 37, forming a stable pressure plate structure that can fix and stabilize the scraper in all directions. A sliding slot 11 is installed on the side wall of the telescopic slot, and a sliding plate is slidably matched in the sliding slot. This sliding slot and the sliding plate form a precise sliding fit, ensuring that the sliding plate can easily adjust its position when needed. A flexible spring 34 is provided between the sliding plate and the top of the sliding slot. The design of this spring provides good buffering and adaptability for the entire chain-pressing plate system.

[0017] The solution is refined, and the flexible spring drives the upper pressure plate and the side pressure plate to press against the top of the scraper plate at the tail of the scraper conveyor. When the scraper conveyor encounters different loads and impacts during operation, the flexible spring can effectively absorb these forces and protect the scraper and the pressure chain plate from damage. At the same time, it can also ensure that the scraper is always in the correct position, improving the accuracy and efficiency of transportation.

[0018] Furthermore, the upper pressing plate is provided with a positioning hole, the top of the side pressing plate is provided with a threaded hole, and a bolt 36 is installed in the positioning hole of the upper pressing plate, and the bolt passes through the positioning hole and is threadedly connected in the threaded hole. In this way, the upper pressing plate and the side pressing plate can be firmly fixed together to form an indestructible whole. This connection method is not only simple and reliable, but also convenient for disassembly and maintenance.

[0019] In at least one embodiment, a guide limit hole 32 is provided on the top of the sliding plate, and a limit rod 33 is threadedly connected to the top of the sliding groove, and the end of the limit rod is inserted into the guide limit hole. In this way, the movement range and position of the sliding plate can be accurately controlled. Through this design, people can easily adjust the distance between the pressure chain plate and the scraper to adapt to different work requirements. This adjustability not only improves the flexibility of the scraper conveyor, but also extends the service life of the equipment.

[0020] Furthermore, the flexible spring is sleeved on the limit rod. This not only ensures the stability and reliability of the spring, but also facilitates replacement and maintenance. People can choose springs with different elastic coefficients to replace the original springs according to actual needs, so as to maintain the best contact state between the pressure plate and the scraper in real time. This design not only improves the performance and service life of the scraper conveyor, but also brings tangible economic benefits and convenience to related industries.

[0021] Working method: install the arc-shaped pressure chain plate on the telescopic slot 1 at the tail of the scraper conveyor, find the preset sliding slot on the side wall of the telescopic slot, and then slide the sliding plate into the sliding slot. Set a flexible spring between the sliding plate and the top of the sliding slot, ensure that one end of the flexible spring is fixed to the top of the sliding slot, and the other end is connected to the top of the sliding plate. Connect the upper pressure plate 35 to the sliding plate, and ensure that the side pressure plate 37 is connected to the bottom of the upper pressure plate. Use bolts 36 to pass through the positioning holes on the upper pressure plate, and then thread it into the threaded holes on the top of the side pressure plate to fix the upper pressure plate and the side pressure plate together. Find the guide limit hole 32 at the top of the sliding plate, and thread the limit rod 33 at the top of the sliding slot, and then adjust the distance of the limit rod inserted into the guide limit hole to adjust the distance between the upper pressure plate, the side pressure plate and the top of the scraper of the scraper conveyor. Ensure that the flexible spring drives the upper pressure plate and the side pressure plate to rest against the top of the scraper of the scraper conveyor and maintain appropriate contact pressure. If necessary, the flexible springs with different elastic coefficients can be replaced to optimize the contact state.

[0022] When the scraper conveyor is running, the arc-shaped pressure chain plate firmly presses the scraper at the tail of the scraper conveyor in the appropriate position through the upper pressure plate and the side pressure plate to ensure the stability and efficiency of the scraper during the conveying process. When the position or contact pressure of the scraper needs to be adjusted, it can be achieved by adjusting the insertion depth of the limit rod in the guide limit hole. If it is found that the elastic force of the flexible spring is insufficient or too large, a flexible spring with an appropriate elastic coefficient can be replaced according to actual needs to maintain the optimal contact state between the pressure plate and the scraper. Regularly check the integrity and tightness of the arc-shaped pressure chain plate and its components. If damaged or loose, they should be repaired or replaced in time.

[0023] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
