Description

Technical Field

[0001] This utility model relates to the technical field of mine car chassis devices, and in particular to a mine car chassis device with end-to-end connection function. Background Technology

[0002] A mining car is a specialized piece of equipment used to transport minerals out of a mine. To facilitate the transportation of minerals, mining cars are generally designed with their ends connected. These mining cars typically have annular connecting sleeves or similar connecting mechanisms at both the front and rear ends of the chassis. These connecting sleeves are fixed to the chassis body via a connecting mounting base.

[0003] However, existing mine car chassis devices with end-to-end connection functions usually use traditional connecting rings for connection. This connection method involves complicated operation steps, is time-consuming and labor-intensive to install, increases working time, is inconvenient for maintenance and upkeep, and the components between the connecting rings wear out more severely, increasing the maintenance cost of the mine car and reducing the economic efficiency of the equipment.

[0004] Therefore, it is necessary to propose a mining car chassis device with end-to-end connection function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mine car chassis device with end-to-end connection function, so as to solve the problems of using traditional connecting rings for connection, which involves complicated operation steps, time-consuming and labor-intensive installation, increased operation time, inconvenient maintenance and upkeep, and severe wear of components between connecting rings, which increases the maintenance cost of the mine car and reduces the economic benefits of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mine car chassis device with end-to-end connection function, comprising a mine car body, wherein a first connecting plate and a connecting block are fixedly connected to both sides of the mine car body plate, a first fixing ring is fixedly connected to the end of the first connecting plate, a columnar block is fixedly connected to the top of the connecting block on the side away from the mine car body, a sliding rod is slidably connected to the middle of the columnar block, and the sliding rod is inserted into the first fixing ring;

[0007] The bottom of the sliding rod is fixedly connected to a snap ring, and multiple balls are arranged in a ring around the outer periphery of the snap ring. An oil cavity is opened inside the first fixed ring. Multiple through holes are evenly opened in a ring near the inner ring of the first fixed ring. An elastic sheet is fixedly connected inside the through holes. The balls move in contact with the elastic sheet. Two oil outlet holes are opened through the oil cavity near the inner ring of the first fixed ring. A second sponge strip is fixedly connected inside the oil outlet holes.

[0008] Preferably, the elastic sheet is elastic and is located at the inner ring of the first fixing ring under normal conditions.

[0009] Preferably, a first sponge strip is fixedly connected to the inner wall of the oil cavity near the inner ring of the first fixing ring, and the inner wall of the first sponge strip is fixedly connected to the side wall of the second sponge strip.

[0010] Preferably, the cylindrical block has a cylindrical groove inside, and a circular ring is slidably connected inside the cylindrical groove. The circular ring is fixedly sleeved on the outer periphery of the sliding rod. A spring is provided inside the cylindrical groove. The top and bottom ends of the spring are movably connected to the top surface of the circular ring and the top surface of the cylindrical groove, respectively. The spring is movably sleeved on the sliding rod.

[0011] Preferably, a second connecting plate is fixedly connected to the bottom of the connecting block on the side away from the mine car body, a second fixing ring is fixedly connected to the end of the second connecting plate, and the sliding rod is slidably connected to the second fixing ring.

[0012] Preferably, a limiting ring is fixedly connected to the bottom of the inner wall of the first fixing ring, and the first fixing ring is located between the cylindrical block and the second fixing ring.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model eliminates the complicated operation steps of traditional connection methods by matching the components. Quick installation can be achieved by pulling the sliding rod upward. The quick installation function allows the mine car body to be connected or separated quickly when needed, which greatly shortens the operation time. This installation structure is simple and easy to maintain and repair.

[0015] 2. In this utility model, during the rotation of the snap ring, the lubricating oil in the oil chamber is squeezed out from the oil outlet at the second sponge strip through the cooperation of the components. This achieves automatic lubrication by lubricating the snap ring and the ball bearings during the movement of the mine car body. This makes the mine car body more smoothly turning or connecting, and also maintains the stable rotation of the snap ring. At the same time, it reduces the wear of the first fixed ring, thereby extending the service life of the first fixed ring, reducing the maintenance cost of the mine car body, and improving the economic efficiency of the equipment.

[0016] 3. Timely addition of lubricating oil can form an oil film between the retaining ring and the first fixed ring, reducing direct contact between the friction parts and thus significantly reducing friction and wear. At the same time, the lubricating oil film can absorb some energy, converting concentrated loads into distributed loads, which helps reduce vibration and noise during bearing operation and improves the stability of equipment operation.

[0024] 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.

[0025] This utility model addresses the problems of traditional connecting rings, which involve complex operation steps, time-consuming and labor-intensive installation, increased work time, and inconvenient maintenance. Furthermore, the components between the connecting rings experience significant wear, increasing the maintenance cost of the mine car and reducing the economic efficiency of the equipment. This invention provides a solution... Figures 1-4The mine car chassis device with end-to-end connection function shown includes a mine car body 1. A first connecting plate 2 and a connecting block 3 are fixedly connected to both sides of the mine car body 1. A first fixing ring 21 is fixedly connected to the end of the first connecting plate 2. A cylindrical block 31 is fixedly connected to the top of the connecting block 3 on the side away from the mine car body 1. A sliding rod 34 is slidably connected to the middle of the cylindrical block 31, and the sliding rod 34 is inserted into the first fixing ring 21. The end-to-end connection structure of the mine car body 1 facilitates the connection and installation of the mine car bodies 1, thus easily meeting different transportation needs. When using the device, multiple mine car bodies 1 are arranged end-to-end in sequence. Pulling the sliding rod 34 on the previous mine car body 1 moves the sliding rod 34, causing the locking ring 35 to move. Moving upwards, a handle for pulling is installed above the sliding rod 34, which is a mature existing technology and will not be described in detail here. Then, the first connecting plate 2 and the first fixing ring 21 on the body 1 of the next mine car are inserted between the cylindrical block 31 and the second fixing ring 33 of the body 1 of the previous mine car. The sliding rod 34 is released, and the sliding rod 34 and the snap ring 35 move downwards and insert into the first fixing ring 21 to complete the connection. Through the cooperation of the components, the complicated operation steps of the traditional connection method are eliminated. Pulling the sliding rod 34 upwards can achieve quick installation. The quick installation function allows the body 1 of the mine car to be connected or separated quickly when needed, which greatly shortens the operation time. This installation structure is simple and easy to maintain and repair.

[0026] It should be noted that there are threads at the bottom of the sliding rod 34, and a threaded sleeve can be installed at the bottom of the sliding rod 34 to help fix the sliding rod 34 more securely. The threads and threaded sleeves are existing technologies and are not shown in the figure, so they will not be described in detail here. Through the cooperation of the threads and threaded sleeves of the sliding rod 34, the sliding rod 34 can be prevented from bumping or shaking during the movement of the mine car body 1, thus ensuring the stability of the connection.

[0027] In this invention, a cylindrical groove 39 is provided inside the cylindrical block 31. A circular ring 37 is slidably connected inside the cylindrical groove 39. The circular ring 37 is fixedly sleeved on the outer periphery of the sliding rod 34. A spring 38 is provided inside the cylindrical groove 39. The top and bottom ends of the spring 38 are movably connected to the top surface of the circular ring 37 and the top surface of the cylindrical groove 39, respectively. The spring 38 is movably sleeved on the sliding rod 34. When installation is required, the sliding rod 34 is pulled, and the sliding rod 34 drives the circular ring 37 to move in the cylindrical groove 39. The cooperation between the circular ring 37 and the cylindrical groove 39 compresses the spring 38. When the sliding rod 34 moves to the position of the first fixed ring 21, the sliding rod 34 is released, and the spring 38 uses its elasticity to restore the circular ring 37 to its original position, thereby allowing the sliding rod 34 to be inserted into the first fixed ring 21 to complete the engagement.

[0028] It should be noted that the bottom of the connecting block 3 on the side away from the mine car body 1 is fixedly connected to the second connecting plate 32, and the end of the second connecting plate 32 is fixedly connected to the second fixing ring 33. The sliding rod 34 is slidably connected to the second fixing ring 33. The sliding rod 34 passes through the first fixing ring 21 and is inserted into the second fixing ring 33, making the connection more stable.

[0029] It should also be noted that a limiting ring 22 is fixedly connected to the bottom of the inner wall of the first fixing ring 21. The first fixing ring 21 is located between the cylindrical block 31 and the second fixing ring 33. The limiting ring 22 plays a limiting role, ensuring that the snap ring 35 is inserted into the appropriate position of the first fixing ring 21, so that the component can operate normally.

[0030] In this invention, a snap ring 35 is fixedly connected to the bottom of the sliding rod 34. Multiple balls 36 are arranged in a ring around the outer periphery of the snap ring 35. An oil cavity 23 is formed inside the first fixed ring 21. Multiple through holes 27 are evenly and uniformly formed in a ring near the inner ring of the first fixed ring 21. An elastic sheet 28 is fixedly connected inside each through hole 27, and the balls 36 movably contact the elastic sheet 28. Two oil outlet holes 26 are formed near the inner ring of the first fixed ring 21 in the oil cavity 23, and a second sponge strip 25 is fixedly connected inside each oil outlet hole 26. After connection, the balls 36 on the snap ring 35 can reduce the friction between the first fixed ring 21 and the snap ring 35, thus making the mine car body 1 smoother when turning or connecting, and maintaining stable rotation of the snap ring 35. Simultaneously, the balls 36 reduce the wear of the first fixed ring 21, thereby extending its service life, reducing the maintenance cost of the mine car body 1, and improving the economic efficiency of the equipment.

[0031] The second sponge strip 25 effectively controls the flow of lubricating oil, preventing excessive throttling that could lead to insufficient lubrication or equipment malfunction.

[0032] Furthermore, during the rotation of the snap ring 35, the ball 36 contacts the elastic sheet 28, compressing the elastic sheet 28. The elastic sheet 28 moves into the oil cavity 23, increasing the pressure inside the oil cavity 23. The lubricating oil inside the oil cavity 23 is then squeezed out from the oil outlet 26 at the second sponge strip 25. This achieves automatic lubrication by lubricating the snap ring 35 and the ball 36 during the movement of the mine car body 1.

[0033] As the retaining ring 35 rotates, lubricating oil can be added in time, forming an oil film between the retaining ring 35 and the first fixed ring 21. This reduces direct contact between the friction components, thereby significantly reducing friction and wear. At the same time, the lubricating oil film can absorb some energy, partially converting concentrated loads into distributed loads, which helps reduce vibration and noise during bearing operation and improves the stability of equipment operation.

[0034] It should be noted that there is a lubricating oil hole and a sealing plug above the oil cavity 23, which is a mature technology in the prior art. It is not shown in the figure and will not be described in detail here.

[0035] In this invention, the elastic sheet 28 is elastic and is normally located at the inner ring of the first fixing ring 21. The elastic sheet 28 can be a rubber sheet or other elastic material, which is not specifically limited here. In normal condition, the elastic sheet 28 is located at the inner ring of the first fixing ring 21. During the rotation of the snap ring 35, the snap ring 35 drives the ball 36 to rotate, and the ball 36 contacts the elastic sheet 28, thereby squeezing the lubricating oil out of the oil cavity 23.

[0036] It should be noted that a first sponge strip 24 is fixedly connected to the inner wall of the oil cavity 23 near the inner ring of the first fixing ring 21. The inner wall of the first sponge strip 24 is fixedly connected to the side wall of the second sponge strip 25. The first sponge strip 24 contacts the top and bottom walls of the oil cavity 23 and can absorb the lubricating oil, thereby effectively controlling the outflow of the lubricating oil.
