[0002] In the field of railway transportation for mining, the transport of bulk solid cargo such as ore is a common operational step. Due to the irregular shape and size of the ore, the ore loaded onto railway freight cars often exhibits uneven stacking. This uneven stacking not only affects the stability of the freight car's center of gravity but may also lead to displacement and spillage of the ore during transportation, increasing the safety risks associated with transport.

[0003] Currently, in order to ensure the stability and safety of trucks during transportation, the ore inside the truck bed needs to be leveled. The traditional leveling method mainly relies on workers using manual tools such as shovels or rakes to flatten the surface of the ore pile. This method has problems such as high labor intensity, low efficiency and unstable leveling effect, so it needs to be improved. Utility Model Content

[0004] One objective of this invention is to provide a cargo leveling device for railway transportation in mines. This invention addresses the problems mentioned in the background that traditional leveling methods mainly rely on workers using manual tools such as shovels or rakes to level the surface of ore piles. This method is characterized by high labor intensity, low efficiency, and unstable leveling results.

[0016] The beneficial effects of this utility model are:

[0017] This utility model, through its gantry assembly and leveling mechanism, effectively avoids the problems of high labor intensity, low efficiency, and unstable leveling effect caused by workers using manual tools such as shovels or rakes to level ore. In use, the first hydraulic cylinder in the moving mechanism pushes the outrigger to rotate towards the ground, so that its moving wheels contact the ground and move, moving the gantry assembly to the position of the mining railway freight car. Then, by driving the second hydraulic cylinder and telescopic rod, the leveling frame, leveling pressure frame, and leveling plate are moved towards the ore position on the top of the car. In conjunction with the moving mechanism, the ore on the top of the car is compacted and leveled. Furthermore, the vibrating plate at the bottom of the leveling frame can increase the density between the ore through vibration, so as to achieve a uniformly distributed level.

[0018] This utility model features an adjustment mechanism in which a motor drives the active bevel gear to rotate. At this time, the bidirectional screw rotates under the meshing connection between the driven bevel gear and the active bevel gear, causing the two fixed supports to extend and retract outside the movable support. Meanwhile, the two leveling sleeves at the bottom also move laterally in sync with the connection between the telescopic rod and the fixed support. This allows the leveling mechanism to be adjusted according to the width of the carriage, thereby improving the leveling efficiency of the ore. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-4A cargo leveling device for railway transportation in mines, comprising:

[0027] The gantry assembly 1 includes a base 101, of which two bases 101 are provided. A column 102 is fixedly mounted on the top of each base 101, and a fixed bracket 104 is fixedly mounted on the top of each column 102. A movable bracket 105 is movably mounted between the two fixed brackets 104. The two fixed brackets 104 slide outside the movable bracket 105 via an adjustment mechanism. The adjustment mechanism includes a bidirectional screw 107, a driven bevel gear 108 fixedly mounted on the outer side of the bidirectional screw 107, and a driving bevel gear 109 meshing with the outer side of the driven bevel gear 108. The moving bevel gear 109 is fixedly mounted on the output end of the motor 110, and the motor 110 is fixedly mounted on the top of the movable bracket 105. The motor drives the active bevel gear to rotate. At this time, the bidirectional screw rotates under the meshing connection between the driven bevel gear and the active bevel gear, so that the two fixed brackets are located on the outside of the movable bracket and can move in an expanding and contracting manner. The two leveling sleeves at the bottom will also move laterally synchronously under the connection between the telescopic rod and the fixed bracket, so that the leveling mechanism can be adjusted according to the width of the carriage to improve the leveling efficiency of the ore.

[0028] The moving mechanism 2 is installed inside the base 101 in the gantry assembly 1 to realize the movement of the device. The moving mechanism 2 includes a rotating shaft 201 and a support block 202. There are two rotating shafts 201. A support leg 203 is rotatably arranged on the outer side of the rotating shaft 201. A slide groove 204 is opened on one side of the support leg 203. A slider 205 is slidably arranged inside the slide groove 204. A moving wheel 206 is symmetrically rotatably arranged at the lower end of one side of the support leg 203. A rotating seat 207 is symmetrically fixed on one side of the support block 202. A first hydraulic push cylinder 208 is rotatably arranged inside the rotating seat 207. The first hydraulic push cylinder in the moving mechanism pushes the support leg to rotate toward the ground, so that the moving wheel contacts the ground and moves. However, after the position movement is completed, the first hydraulic push cylinder can be driven again to make the support leg and moving wheel retract into the base and be stably supported on the ground by the base. This can improve the leveling stability of the leveling mechanism in the carriage.

[0029] A leveling mechanism 3, installed at the bottom of the fixed bracket 104 in the gantry assembly 1, is used to level the mining railway cargo on the freight car. The leveling mechanism 3 includes a second hydraulic cylinder 301 and a telescopic rod 302. The second hydraulic cylinder 301 is fixedly installed at the bottom of the movable bracket 105, and the telescopic rod 302 is fixedly installed at the bottom of the fixed bracket 104. A leveling pressure frame 304 and a leveling sleeve 303 are respectively fixedly installed at the output ends of the second hydraulic cylinder 301 and the telescopic rod 302. The leveling pressure frame 304 and the leveling sleeve 303... A flat plate 305 is fixedly installed at the bottom of the frame 303, and a vibrating plate 306 is fixedly installed at the bottom of the flat plate 305. By driving the second hydraulic push cylinder and the telescopic rod, the flat frame, flat press frame and flat plate are moved towards the position of the ore on the top of the car. By cooperating with the moving mechanism, the ore on the top of the car is compacted and flattened. The vibrating plate at the bottom of the flat frame can increase the density between the ore through vibration, so as to achieve a flattened uniform distribution. The density between the ore is increased by using the method of compaction and flattening.

[0030] Example 1: A counterweight 103 is symmetrically fixed on one side of the top of the base 101 to increase the stability of the device during the leveling process. A power distribution box 111 is fixed on one side of the base 101 to control the operation of the device. The upper and lower ends of the fixed bracket 104 are respectively provided with clearance grooves 106.

[0031] Example 2: The output ends of the slider 205 and the first hydraulic push cylinder 208 are rotatably connected. The leveling frame 304 is located inside the leveling frame 303 and can be moved synchronously with the fixed support. A material level sensor 307 is fixedly installed on one side of the leveling plate 305, which can monitor the height of the material in the carriage and avoid overloading.

[0032] Working principle: First, the first hydraulic cylinder 208 in the moving mechanism 2 pushes the outrigger 203 to rotate, causing the moving wheel 206 to contact the ground, realizing the overall movement of the device. After reaching the position, the first hydraulic cylinder 208 actuates again, causing the outrigger and moving wheel 206 to retract into the base 101, where they are stably supported, ensuring the stability of the leveling mechanism in the carriage. Next, the motor 110 in the gantry assembly 1 drives the active bevel gear 109 to rotate. Through the meshing of the driven bevel gear 108 and the bidirectional screw 107, the two fixed supports 104 extend and retract outside the movable support 105, and the leveling frame 303 moves laterally in sync to adapt to carriages of different widths. The leveling mechanism 3 then begins to work, and the second hydraulic cylinder... The push cylinder 301 and the telescopic rod 302 push the leveling frame 303, the leveling pressure frame 304, and the leveling plate 305 upward to compact and level the ore on the top of the car. The vibration of the vibrating plate 306 increases the density between the ore, achieving uniform distribution and thus improving the leveling efficiency. The counterweight 103 increases the stability of the device. The power distribution box 111 controls the operation of the device. The clearance groove 106 facilitates adjustment. In embodiment 2, the slider 205 and the first hydraulic push cylinder 208 are rotated. The leveling pressure frame 304 moves inside the leveling frame 303. The material level sensor 307 monitors the material height to prevent overloading. Through this series of actions, the device can efficiently and stably complete the leveling operation of mine railway transport goods.
