Description

Technical Field

[0001] The present invention belongs to the technical field of mine car transportation, and particularly relates to an anti-dumping mine car box. Background Art

[0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

[0003] Mine cars are common means of transporting bulk materials such as ore, waste rock and coal in mines. Mine cars are used as the main means of transporting mined ore on most transportation lines. When mine cars travel to and from the mine, the roads they take are complex, changeable and bumpy due to mineral mining. In addition, most mine cars are loaded heavily and heavily during transportation. Once they encounter potholes and fail to avoid them in time, it is easy for the car body to tip over due to direction deviation during the avoidance process, causing the car body transporting the minerals to overturn. At this time, the ore in the car body will squeeze and deform the baffle on the side of the overturned car body. Utility Model Content

[0004] The purpose of the present disclosure is to provide an anti-dumping mining car box, which can at least solve one of the above technical problems.

[0005] To achieve the above-mentioned objectives, one or more embodiments of the present disclosure provide an anti-dumping mine car box, including a box body, wherein semicircular grooves and dumping discharge doors are provided on the side walls on the left and right sides of the forward direction of the box body, and the semicircular grooves are located on both sides of the dumping discharge door. Anti-dumping columns are provided inside the semicircular grooves, and the upper part of the anti-dumping column and the upper part of the dumping discharge door are connected by a transmission shaft.

[0006] Furthermore, it also includes an anti-dump shell, which is arranged at the bottom of the side wall at the front end of the vehicle body in the forward direction. The interior of the anti-dump shell is a cavity structure. A transmission screw horizontally and perpendicular to the forward direction of the vehicle body is arranged in the middle position of the cavity structure, and a counterweight block for changing the center of gravity of the vehicle body is arranged on the transmission screw.

[0007] Furthermore, the first servo motor is fixedly arranged on the side wall of the vehicle body; the two sides of the dumping and unloading door are plug-connected to the side wall of the vehicle body through limit blocks.

[0008] Furthermore, rectangular cavities are provided at both left and right ends inside the dumping and unloading door, a transmission plate is provided in the rectangular cavity, and a special-shaped block is provided on the upper part of the transmission plate, which is sleeved on the transmission shaft and driven to rotate by the transmission shaft. The special-shaped block is always in contact with the transmission plate when rotating, and a second spring is provided between the lower part of the transmission plate and the lower end surface of the rectangular cavity.

[0009] Furthermore, the left and right side walls of the dumping and unloading door are provided with limiting slide grooves for limiting the position of the limiting blocks, the upper and lower ends of the side of the transmission plate in contact with the dumping and unloading door are provided with sliders, and the other side is provided with multiple sets of triangle plates at equal distances.

[0015] The beneficial effects of one or more of the above technical solutions are:

[0016] 1. This disclosure utilizes a first servo motor to drive a transmission shaft, deploying anti-dumping posts and a dumping door when the vehicle body tilts. After the dumping door deploys, minerals within the vehicle body flow smoothly out through the channel. This effectively reduces the weight of the vehicle body and prevents bending or damage to the anti-dumping posts caused by the crushing of minerals, thereby preventing deformation of the vehicle body sidewalls.

[0017] 2. The present invention drives the counterweight block to move accordingly by driving the transmission screw through the second servo motor, thereby changing the tilt state of the vehicle body before a tipping accident occurs, ensuring that the center of gravity of the vehicle body remains in a relatively stable state.

[0028] like Figure 1-Figure 7 As shown, this embodiment provides an anti-dumping mining car box, including a box body 1 and an anti-dumping shell 2.

[0029] like Figure 1 As shown, the anti-dumping shell 2 is arranged at the bottom of the side wall at the front end of the vehicle body 1 in the forward direction, and semicircular grooves 6 and dumping discharge doors 8 are provided on the side walls on the left and right sides of the vehicle body 1 in the forward direction. A connecting ring 3 is fixedly connected to the middle part of the outer end face of the anti-dumping shell 2, and the interior of the connecting ring 3 is rotatably connected to a connecting column 4 through a bearing, and the end of the connecting column 4 is fixedly connected to a connecting block 5, and the connecting block 5 is connected to the traction equipment.

[0030] Specifically, the semicircular groove 6 is arranged on both sides of the dumping and unloading door 8, and an anti-dumping column 7 is arranged inside the semicircular groove 6. The upper part of the anti-dumping column 7 is provided with a through hole, and the upper part of the dumping and unloading door 8 is a through hole. The anti-dumping column 7 and the upper part of the dumping and unloading door 8 are connected through a transmission shaft, and the anti-dumping column 7 and the dumping and unloading door 8 are transitionally matched with the transmission shaft.

[0031] like Figure 1 and Figure 2 As shown, the two sides of the dumping and unloading door 8 are connected to the side walls of the car body 1 through limit blocks 10; the interior of the anti-dumping shell 2 is a cavity structure, and a transmission screw 21 horizontally and vertically to the forward direction of the car body 1 is provided in the middle position of the cavity structure, and a counterweight block 22 for changing the center of gravity of the car body 1 is provided on the transmission screw 21.

[0032] Specifically, such as Figure 5 As shown, a second servo motor 20 is mounted at the end of a transmission screw 21. The second servo motor 20 is bolted to the inner sidewall of the anti-dump housing 2. The counterweight 22 has a square cross-section and is provided with rollers 23 at each of its four corners. The second servo motor 20 drives the transmission screw 21 to rotate forward and backward, thereby changing the position of the counterweight 22 and the center of gravity of the vehicle body 1. The rollers 23 ensure smoother movement of the counterweight 22.

[0033] like Figure 2 and Figure 8 As shown, the upper parts of the anti-tipping column 7 and the dumping discharge door 8 are connected by a transmission shaft 9, and the transmission shaft 9 is rotatably connected to the vehicle body 1 through a bearing. The transmission shaft 9 is close to the end of the vehicle body 1 in the forward direction, and a first servo motor 11 for driving the transmission shaft 9 to rotate is provided. The first servo motor 11 is fixed on the side walls on the left and right sides of the vehicle body 1 by bolts. The forward and reverse rotation of the transmission shaft 9 driven by the first servo motor 11 can drive the anti-tipping column 7 and the dumping discharge door 8 to rotate outward or retract inward relative to the side walls on the left and right sides of the vehicle body 1 in the forward direction.

[0034] like Figure 3 As shown, rectangular cavities 12 are provided at both ends of the inside of the dumping and unloading door 8, and a transmission plate 13 is provided in the rectangular cavity 12. The upper part of the transmission plate 13 is provided with a special-shaped block 25 which is sleeved on the transmission shaft 9 and driven to rotate by the transmission shaft 9. The special-shaped block 25 is always in contact with the transmission plate 13 when rotating; a second spring 15 is provided between the lower part of the transmission plate 13 and the lower end surface of the rectangular cavity 12.

[0035] Specifically, such as Figure 5As shown, the special-shaped block 25 is a cam structure, which can push the transmission plate 13 to move downward to the distance of the equipment when it rotates, so that it is stuck in the set position and continues to drive the dumping and unloading door 8 to rotate. The second spring 15 can make the upper end of the transmission plate 13 always fit the outer contour of the special-shaped block 25.

[0036] like Figure 3 and Figure 4 As shown, the left and right side walls of the dumping and unloading door 8 are provided with limiting slide grooves for limiting the position of the limiting block 10, and the upper and lower ends of the side where the transmission plate 13 contacts the dumping and unloading door 8 are provided with sliders 14, and the other side is provided with multiple sets of triangle plates 16 at equal distances.

[0037] Specifically, the slider 14 is movably inserted into the limiting groove provided on the side wall of the dumping and unloading door 8, and a limiting column 17 is provided between the triangular plate 16 and the limiting block 10. A retaining ring 18 is provided at the connection between the limiting column 17 and the triangular plate 16. A first spring 19 is sleeved on the limiting column 17, and the first spring 19 is limited between the retaining ring 18 and the side wall of the rectangular cavity 12. The end face of the limiting column 17 close to the triangular plate 16 is a slope, and the slope is in contact with the corresponding slope of the triangular plate 16.

[0038] like Figure 1 and Figure 7 As shown, an angle sensor 24 is fixedly connected to the middle of the side wall of the vehicle body 1. The angle sensor 24 is connected to the vehicle host 23 through wires. The vehicle host 23 is connected to the first servo motor 11 and the second servo motor 20 through wires and controls the first servo motor 11 and the second servo motor 20.

[0039] Working principle:

[0040] When the device is in use, the connecting block 5 is connected to the traction device through a pin, and the connecting column 4 is rotatable. In this way, when the vehicle body 1 falls over, the traction device will not fall over as well, which can protect the driver inside the traction device.

[0041] When the vehicle body 1 is in normal driving, the angle sensor 24 will monitor the tilt angle of the vehicle body 1 in real time. When the angle sensor 24 is between plus or minus 45 degrees, that is, when the vehicle body 1 is tilted to the left in the forward direction of the vehicle body 1, the on-board host 23 will control the second servo motor 20 to drive the screw 21 to rotate forward, thereby driving the counterweight 22 to move to the right in the forward direction of the vehicle body 1 on the transmission screw 21, thereby causing the center of gravity of the vehicle body 1 to shift to the right in the forward direction of the vehicle body 1, and changing the tilt state of the vehicle body 1. Similarly, when the vehicle body 1 tilts to the right, the on-board host 23 will control the second servo motor 20 to drive the screw 21 to rotate forward, thereby driving the counterweight 22 to move to the left in the forward direction of the vehicle body 1 on the transmission screw 21, thereby causing the center of gravity of the vehicle body 1 to shift to the left, and changing the right tilt state of the vehicle body 1, thereby effectively preventing the vehicle body 1 from tipping over.

[0042] When the tilt angle of the car body 1 exceeds plus or minus 45 degrees, the car body 1 will basically tip over. At this time, the angle sensor 24 transmits the detected data to the on-board host 23, that is, the first servo motor 11 on the left side is started when the car body 1 tips over to the left side in the forward direction, and the first servo motor 11 on the right side is started when the car body 1 tips over to the right side, and then the transmission shaft 9 is driven to rotate, so that the anti-tipping column 7 opens and supports the tipping car body 1, and as the transmission shaft 9 rotates, the limit block 10 is also contracted and the tipping discharge door 8 is opened outward, so that the mineral material of the car body 1 is accumulated under the tipping side of the car body 1, so that the mineral material can support the car body 1, and it will also reduce the weight of the car body 1 without causing the anti-tipping column 7 to be bent and damaged.

[0043] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Those skilled in the art should understand that on the basis of the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure.
