Description

Technical Field

[0001] This utility model relates to the technical field of special equipment for mines, specifically an anti-tipping mine car. Background Technology

[0002] In the process of mining ore, mine cars are generally used. A mine car is a small vehicle used to transport minerals. Usually, the mine car is filled with ore and then transported to a designated location.

[0003] A mining car with publication number CN 221519621 U is disclosed, relating to the technical field of mining equipment. This utility model includes a mining car and a slide rail. The mining car is slidably mounted on the slide rail. A support plate is installed on the side wall of the mining car, and a chain is connected to the support plate. The other end of the chain is connected to a limit clamp, which is fitted onto the rim of the mining car's roller. This utility model has a simple structure. During the operation of the mining car, the limit clamp is hung on the support plate. When the mining car needs to stop, the limit clamp is removed from the support plate and engaged with the rim of the roller. The limit clamp restricts the rotation of the roller, thus completing the parking of the mining car, avoiding the problem of having to carry a car cover at all times for parking.

[0004] However, the aforementioned mining cars still have some shortcomings in use. When loading, uneven material stacking or a shift in the center of gravity can easily cause the car to tilt. During operation, uneven tracks, centrifugal force during turns, or local deformation or changes in track gradient can further exacerbate lateral swaying. Traditional mining cars have relatively simple anti-tipping structures, lacking effective lateral restraint and buffering mechanisms. They rely solely on the contact between the wheel flanges and the track to limit lateral displacement. When the lateral force exceeds the bearing limit, tipping accidents are very likely to occur, causing not only spillage of mineral resources and transportation disruptions but also potential damage to equipment and even endangering the personal safety of workers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-tipping mine car, solving the problem that uneven material stacking or a shifted center of gravity during loading can easily cause the car to tilt. Furthermore, during operation, uneven tracks, centrifugal forces during turns, or localized track deformation and changes in gradient can further exacerbate lateral swaying. Traditional mine cars have relatively simple anti-tipping structures, lacking effective lateral restraint and buffering mechanisms. They rely solely on the contact between the wheel flanges and the track to limit lateral displacement. When the lateral force exceeds the tolerance limit, tipping accidents are highly likely to occur, causing not only spillage of mineral resources and transportation disruptions but also potential equipment damage and even endangering the personal safety of workers.

[0006] This utility model provides the following technical solution: an anti-tipping mine car, including guide rails and a mine car, wherein there are two guide rails, the mine car is set on the two guide rails, and support frames are fixedly connected to both sides of the mine car;

[0007] Both of the support frames are rotatably mounted with bidirectional lead screws, and two lead screw sleeves are threaded onto the surfaces of the two bidirectional lead screws. Both of the support frames are fixedly connected with slide rods, and two slide sleeves are slidably fitted onto the surfaces of the two slide rods. Each lead screw sleeve and each slide sleeve is fixedly connected to a mounting frame at its bottom end, and each mounting frame is provided with a limit component inside.

[0008] Preferred technical solution 1: A connecting plate is fixedly connected between each lead screw sleeve and the corresponding sliding sleeve.

[0009] Preferred technical solution 2: The limiting component includes multiple dampers fixedly installed on the inner wall of the mounting frame, one end of the multiple dampers is fixedly connected to a connecting frame, and multiple rollers are rotatably installed between the inner top wall and bottom wall of the connecting frame.

[0010] Preferred technical solution 3: The limiting component further includes two sets of fixing plates fixedly installed inside the mounting frame. Each of the two sets of fixing plates is fixedly connected to a limiting rod. A limiting sleeve is slidably sleeved on the surface of each of the two limiting rods. Each limiting sleeve is movably connected to the connecting frame by a connecting rod. A spring is fixedly connected between the side of each limiting sleeve and the corresponding fixing plate. The spring is sleeved on the limiting rod.

[0011] Preferred technical solution four: One end of each of the bidirectional lead screws extends to the outside of the connected support frame and is fixedly connected to an operating panel.

[0012] Preferred technical solution five: Each of the rollers is made of rubber.

[0013] Compared with the prior art, this utility model provides an anti-tipping mine car with the following advantages: During use, rotating the control panel drives the bidirectional lead screw to rotate, thereby moving the lead screw sleeve and the connected sliding sleeve, causing the rollers to come close to both sides of the track. The rollers prevent the mine car from tipping over. If a tipping occurs, the springs and dampers will generate a certain force between themselves and the guide rail, which can alleviate or correct the mine car to a certain extent, thus preventing it from tipping over. Simultaneously, by adjusting the distance between the two connecting frames, it can be adapted to tracks of different widths, making it more versatile. During use, the distance between the rollers is adjusted via the bidirectional lead screw to adapt to different tracks; the rollers stay close to both sides of the track to prevent tipping, and the springs and dampers buffer and correct tilting, improving stability.

[0018] Please see Figure 1-3 ,

[0019] Example 1: An anti-tipping mine car includes a guide rail 1 and a mine car 2. There are two guide rails 1, and the mine car 2 is set on the two guide rails 1. Support frames 3 are fixedly connected to both sides of the mine car.

[0020] Two bidirectional lead screws 4 are rotatably mounted on the surfaces of the two support frames 3. Two lead screw sleeves 5 are threaded onto the surfaces of the two bidirectional lead screws 4. Slide rods 6 are fixedly connected to the surfaces of the two support frames 3. Two slide sleeves 7 are slidably mounted on the surfaces of the two slide rods 6. An installation frame 8 is fixedly connected to the bottom end of each lead screw sleeve 5 and each slide sleeve 7. A limit component is provided inside each installation frame 8.

[0021] Example 2: The difference between this example and Example 1 is that each lead screw sleeve 5 and the corresponding sliding sleeve 7 are fixedly connected by a connecting plate 9.

[0022] Example 3: The difference between this example and Example 1 is that the limiting component includes multiple dampers 10 fixedly installed on the inner wall of the mounting frame 8, one end of the multiple dampers 10 is fixedly connected to a connecting frame 11, and multiple rollers 12 are rotatably installed between the inner top wall and bottom wall of the connecting frame 11.

[0023] Example 4: The difference between this example and Example 1 is that the limiting component further includes two sets of fixing plates 16 fixedly installed inside the mounting frame 8. Each set of fixing plates 16 is fixedly connected to a limiting rod 13. A limiting sleeve 14 is slidably sleeved on the surface of each limiting rod 13. Each limiting sleeve 14 is movably connected to the connecting frame 11 by a connecting rod 15. A spring 17 is fixedly connected between the side of each limiting sleeve 14 and the corresponding fixing plate 16. The spring 17 is sleeved on the limiting rod 13 and provides a certain corrective and relief support force when the mine overturns.

[0024] Example 5: The difference between this example and Example 1 is that one end of each bidirectional lead screw 4 extends to the outside of the connected support frame 3 and is fixedly connected to an operation panel 18, which facilitates operation by the user.

[0025] Example 6: The difference between this example and Example 1 is that each roller 12 is made of rubber.

[0026] In summary, this anti-tipping mine car, when in use, rotates the operating panel 18 to drive the bidirectional lead screw 4 to rotate, thereby moving the lead screw sleeve 5 and the connected sliding sleeve 7, so that the rollers 12 are close to both sides of the track 1. The rollers 12 prevent the mine car 2 from tipping over. If a tipping occurs, the spring 17 and the damper 10 will generate a certain force between themselves and the guide rail 1, which can alleviate or correct the mine car to a certain extent, thereby preventing the mine car from tipping over. At the same time, by adjusting the distance between the two connecting frames 11, it can be adapted to track 1 of different widths, making it more versatile. When in use, the distance between the rollers is adjusted by the bidirectional lead screw to adapt to different tracks; the rollers are close to both sides of the track to prevent tipping over, and the springs and dampers buffer and correct tilting, improving stability.
