[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figs. 1-3 This utility model provides an embodiment of a buffer stop, including a mounting rail 1, a stopper frame 3 fixedly connected to the front side of the mounting rail 1, a cylinder 4 fixedly connected to the upper part of the stopper frame 3, a front trolley lifting claw 2 fixedly connected to the middle of the mounting rail 1, a stopper mounting bracket 6 fixedly connected to the middle of the front side of the mounting rail 1, a stop plate assembly 5 fixedly connected to the output end of the cylinder 4, and a buffer assembly provided at the lower part of the stop plate assembly 5 to reduce the impact between the cargo trolley and the stopper. The buffer assembly includes a fixed moving seat 7, which is located at the lower part of the stop plate assembly 5, and has two front and rear sections inside the fixed moving seat 7. A mounting shaft 10 is fixedly connected to each side. A buffer spring 11 is provided on the outside of the mounting shaft 10. A floating seat 8 is slidably connected to the outside right side of the mounting shaft 10. A hydraulic buffer device 9 is fixedly connected to the outside of the floating seat 8. One end of the buffer spring 11 is fixedly connected to the floating seat 8, and the other end of the buffer spring 11 is fixedly connected to the mounting shaft 10. The right side of the fixed moving seat 7 is fixedly connected to the stop mounting bracket 6. The floating seat 8 is slidably connected inside the fixed moving seat 7. The stop plate assembly 5 is fixedly connected to the floating seat 8. The end of the hydraulic buffer device 9 away from the floating seat 8 is fixedly connected to the inner wall of the fixed moving seat 7.
[0029] When the trolley stops, the stop plate assembly 5 drives the floating seat 8 to slide outside the mounting shaft 10. When the floating seat 8 slides, it effectively transmits the impact force to the hydraulic buffer device 9 by squeezing the mounting shaft 10. At this time, the piston inside the hydraulic buffer device 9 begins to move in the hydraulic oil. As the piston moves, it forces the hydraulic oil to flow through the internal flow-limiting channels. The viscosity of the hydraulic oil and the flow restriction work together to help absorb and consume the impact energy, reduce the violent impact generated when the trolley stops, and ensure that the buffer stop provides sufficient buffering force during operation. At the same time, the buffer stop can flexibly adjust the buffering force according to different application requirements, thereby improving the adaptability and reliability of the system and enabling the stop to be used in a wider range of installation environments.
[0030] Reference Figs. 1-3 The fixed moving seat 7 is made of steel, the mounting shaft 10 is made of alloy steel, and the floating seat 8 is made of steel. A copper alloy oil-free bushing is installed at the connection between the mounting shaft 10 and the floating seat 8. The graphite coating in the copper alloy oil-free bushing ensures wear resistance while also providing lubrication.
[0031] By using steel to ensure the strength and stability of the fixed moving seat 7, it can stably withstand various pressures and loads generated during mechanical movement, avoiding the impact of deformation or damage on the normal operation of the equipment. By using alloy steel to provide strong wear resistance and corrosion resistance to the mounting shaft 10, the service life of the mounting shaft 10 can be effectively extended even when used in long-term high-load or humid environments, avoiding performance degradation due to wear or corrosion. By using copper alloy oil-free bushings to provide good sliding performance and a low coefficient of friction to the floating seat 8, the smooth operation of the buffer stop is ensured, and the efficiency and stability of the equipment are further improved, and the service life of the buffer stop is extended. This reduces the costs caused by frequent maintenance, thereby reducing the burden on customers and enhancing the product's competitiveness and broad promotion potential in the market.
[0032] Working principle: When the cargo trolley is stopped, the stop plate assembly 5 drives the floating seat 8 to slide outside the mounting shaft 10. The floating seat 8 slides and squeezes the mounting shaft 10, and at the same time inputs the impact into the hydraulic buffer device 9, causing the piston inside the hydraulic buffer device 9 to move in the hydraulic oil. The pressure generated forces the hydraulic oil to flow through the flow-limiting orifice or valve. During the flow, the viscosity of the hydraulic oil and the flow restriction help absorb and consume the impact energy. In this way, the buffer stop can adjust the buffer force while ensuring the buffer force, making the installation range of the stop wider.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
