Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, in particular to mining transportation equipment. Background Art

[0002] The mining methods of mines are mainly divided into open-pit mining and underground mining. Among them, underground mining occupies an important position in the mining of deep ores. Underground mining obtains ore by opening channels such as mine caves, tunnels and shafts in the underground ore body. The channel is usually designed as a mesh structure to achieve all-round mining of the ore body. After the ore is mined, it is transported from the inside of the mine cave to the surface by mine cars for further processing. Mine transportation equipment plays a key role in the entire mining process, and its efficiency directly affects the overall output of mining. Therefore, the design and layout of mine transportation equipment has become an important part of mine mining engineering. With the increase in mining depth and the complexity of ore body morphology, the requirements for mine transportation equipment are getting higher and higher, especially in terms of flexibility and efficient transportation capacity in a small space. New challenges have been posed.

[0003] In traditional mine transportation, the steering operation of the mine car often becomes a problem, especially in the narrow mine environment, the steering operation is more complicated. Usually, in order to realize the steering of the mine car in the mine, a Y-shaped track is designed inside the mine, and a two-way mine car is used in conjunction. Although this design enables the mine car to complete the switching of the front and rear directions in a limited space, it still has certain limitations. In the prior art, the mine car operating console is usually set on one side of the bucket, or the bucket is set on both sides, and the operating console is configured in the middle. Although this layout can realize the normal driving of the vehicle in the forward and backward directions, when the vehicle is driving in the opposite direction, the operator cannot observe the road conditions and the bucket conditions at the same time. Especially when the bucket is fully loaded and the overall weight of the vehicle is large, the driver cannot fully grasp the status of the vehicle and the road conditions, which can easily lead to safety hazards.

[0052] Example

[0053] See also Figure 1-11 As shown, the present invention provides a technical solution for a mining transportation equipment: a mining transportation equipment, comprising a carrier plate 1, an inner cavity 2 at the lower end of the carrier plate 1, and a bucket 3 installed on the carrier plate 1, a two-way driving mechanism 4 is installed at the bottom of the carrier plate 1, and a locking mechanism 5 is designed on the two-way driving mechanism 4 for limiting its movement, and operating tables 6 are designed on both sides of the carrier plate 1, wherein any operating table 6 can realize independent control of the two-way driving mechanism 4 or the locking mechanism 5. In the above, the bucket 3 is used to load ore and other transportation materials, the two-way driving mechanism 4 is used to drive the vehicle forward or backward, the locking mechanism 5 can be used to lock or unlock the two-way driving mechanism 4, or to decelerate the two-way driving mechanism 4 during movement, and the design of the double operating tables 6 ensures that the driver can observe the road conditions and the state of the bucket 3 in real time during transportation, so that when encountering uneven tracks or sloped tracks, the speed can be adjusted in time to ensure the safety and efficiency of transportation.

[0054] The bidirectional driving mechanism 4 includes a first motor 401, a transmission shaft 405, and a plurality of bearing seats 409. The first motor 401 is installed at the lower end of the carrier plate 1. The first motor 401 is provided with two control ends 402. Each control end 402 includes two control switches 403 for making the first motor 401 rotate forward or reverse. The control switches 403 are respectively located on different operating tables 6. A main gear 404 is provided at the output end of the first motor 401. First sub-gears 406 are provided on both sides of the transmission shaft 405, one of the first sub-gears 406 is connected to the main gear 404, and the other end of the transmission shaft 405 is connected to the wheel shaft assembly 407. An independent locking mechanism 5 is provided on each transmission shaft 405. A second sub-gear 408 is provided at the end of the wheel shaft assembly 407, and the second sub-gear 408 is meshed with the first sub-gear 406 at the other end of the transmission shaft 405. The bearing seat 409 is provided at the lower end of the carrier plate 1, and the bearing seat 409 is used to support the transmission shaft 405 or the wheel shaft assembly 407 respectively. In this embodiment, the structure of the axle assembly 407 is as follows: Figure 3 As shown, each axle assembly 407 includes two axles restricted in a bearing seat 409, and a wheel portion at the end of the axle. In this embodiment, the first motor 401 is a DC motor, and the forward or reverse control switch 403 is connected to the corresponding first motor 401 control end 402 (i.e., the positive or negative pole of the motor) through a relay, and the first motor 401 is powered by an external power supply device. When controlling the movement of the bidirectional drive mechanism 4, the driver needs to touch the forward or reverse control switch 403 according to the actual situation. When the first motor 401 receives a rotation instruction, the main gear 404 rotates and drives the transmission shafts 405 on both sides to rotate, and then the other end of the transmission shaft 405 transmits the wheel axle assembly 407 through two meshing auxiliary teeth to realize the forward or backward movement control of the device.

[0055] The locking mechanism 5 includes a plurality of shafts 501, an upper clamping plate 502 and a lower clamping plate 503, two second through holes 507, a plurality of first ropes 508, a guide tube 510, a support frame 513 and a limiting rod 514. The shaft 501 is installed at the lower end of the carrier plate 1 and is located on both sides of the transmission shaft 405. The upper clamping plate 502 and the lower clamping plate 503 are slidably installed on the shaft 501 and are located on the outer side of the transmission shaft 405. The facing surfaces of the upper clamping plate 502 and the lower clamping plate 503 are both provided with friction portions 504 matching the transmission shaft 405. A spring 505 is installed between the upper clamping plate 502 and the lower clamping plate 503. The inner sides of the upper clamping plate 502 and the lower clamping plate 503 are both provided with first through holes 506 and second through holes 507 which are mutually offset. The first rope 508 is provided on the bearing seat 409, and is staggered and fixed at different positions of the facing surfaces of the upper clamping plate 502 and the lower clamping plate 503. After each first rope 508 passes through the first through hole 506, a second rope 509 is formed on the outer side of the upper clamping plate 502 or the lower clamping plate 503. The outlet pipe 510 is installed on the side wall of the inner cavity 2. The second rope 509 passes through the second through hole 507 and the outlet pipe 510 to form a third rope 511. The end of the third rope 511 is connected with a pressure rod 512. The support frame 513 is installed on the operating table 6. The pressure rod 512 is rotatably connected with the support frame 513. The limiting rod 514 is rotatably installed on the operating table 6. The limiting rod 514 is used to selectively limit the movement of the pressure rod 512. In the design, the spring 505 is used to ensure that the upper clamping plate 502 and the lower clamping plate 503 are separated and are not in contact with the transmission shaft 405. The friction part 504 can be made of rubber material. When the equipment needs to be suspended on the track or needs to slow down, the driver presses down the operating end of the pressure rod 512, and the other end of the pressure rod 512 tilts up. The tilted end generates a pulling force on the entire rope body, and prompts the upper clamping plate 502 and the lower clamping plate 503 to move toward each other, clamping the intermediate transmission shaft 405. After clamping, the transmission shaft 405 is subjected to friction resistance, thereby limiting or reducing its movement speed. When the movement of the equipment needs to be limited for a long time, the driver rotates the limiting rod 514 after pressing down the pressure rod 512, so that the curved part of the limiting rod 514 hooks the end of the pressure rod 512. At this time, the transmission shaft 405 will be firmly restricted between the upper clamping plate 502 and the lower clamping plate 503, so that the equipment is in a stable long-term braking state when it stops on an uneven road section or a slope section, or when it needs to get off the vehicle for operation.

[0056] The inner cavity 2 is provided with a rotating bracket assembly 7 for improving the flexibility of the locking mechanism 5. The rotating bracket assembly 7 includes a plurality of first rotating brackets 701, a plurality of second rotating brackets 702, and a third rotating bracket 703. The first rotating brackets 701 are respectively mounted at the first through holes 506 on the outer sides of the upper clamping plate 502 and the lower clamping plate 503. The first rotating bracket 701 is used to prevent the first rope 508 from rubbing against the first through hole 506. The second rotating brackets 702 are respectively mounted on the outer sides of the upper clamping plate 502 and the lower clamping plate 503. The third rotating bracket 703 is fixedly mounted at the inlet end of the outlet pipe 510. The second rotating bracket 702 and the third rotating bracket 703 are used to prevent the second rope 509 from rubbing against the second through hole 507. In this embodiment, the structures of the first rotating bracket 701, the second rotating bracket 702, and the third rotating bracket 703 are as follows: Figure 4-6 As shown, the first rotating bracket 701 and the second rotating bracket 702 have substantially the same structure, both including a set of vertical poles, with a rotating shaft arranged between the vertical poles, and the upper and lower ends of the third rotating bracket 703 are fixed to the inner wall of the inner cavity 2, and two sets of identical rotating guide wheels are arranged on the third rotating bracket 703. In order to prevent the rope from rubbing against the edges of other components and generating resistance during the movement, a rotating bracket assembly 7 is designed. The first rotating bracket 701 guides the moving path of the first rope 508 to prevent the first rope 508 from rubbing against the outer edge of the first through hole 506 and the hole wall, and the second rotating bracket 702 and the third rotating bracket 703 guide the moving path of the second rope 509 to prevent the second rope 509 from rubbing against the outer edge of the second through hole 507 and the hole wall. In addition, the risk of the second rope 509 being entangled in the gear part when entering the outlet pipe 510 can be eliminated.

[0057] A support plate 8 is provided at the upper end of the carrier plate 1, and both ends of the bucket 3 are rotatably connected to the support plate 8, and a bucket overturning mechanism 9 is installed on both sides of the bucket 3. The bucket overturning mechanism 9 includes two groups of lever brackets 901, two groups of second motors 905, and a plurality of tension belts 906. The lever brackets 901 are fixed on the carrier plate 1 and are respectively located on both sides of the bucket 3. The lever brackets 901 are designed with an extension part 902, and the first rotating shaft 903 and the second rotating shaft 904 are respectively installed at both ends of the extension part 902. The output ends of the second motor 905 are respectively installed on different first rotating shafts 903. One end of the tension belt 906 is connected to the bucket 3, and the other end of the tension belt 906 is connected to the first rotating shaft 903. The second rotating shaft 904 contacts the side of the tension belt 906, so that the tension belt 906 always maintains a non-linear state. In order to facilitate the loading and unloading of ore, the driver can operate one of the second motors 905 to rotate, and after the rotation, one end of the bucket 3 is turned over under the action of the tension belt 906, so that the filling port faces the loading and unloading end, reducing the loading and unloading height and improving the loading and unloading efficiency. The design of the lever bracket 901 can decompose the vertical pulling force into vertical force and horizontal force, which has a labor-saving effect, reduces the power demand of the second motor 905 and the weight of the motor body, and reduces the bearing pressure on the operating platform 2.

[0058] The outlet tube 510 includes a tube body 5101, two first rotating rods 5102, and a second rotating rod 5103. The tube body 5101 is installed on the side wall of the inner cavity 2. The first rotating rod 5102 is respectively installed on the upper and lower sides of the inlet end of the tube body 5101, and the second rotating rod 5103 is installed at the upper end of the outlet end of the tube body 5101. The first rotating rod 5102 and the second rotating rod 5103 are used to prevent the second rope 509 and the third rope 511 from rubbing against the tube body 5101. The establishment of the outlet tube 510 can further reduce the friction of the rope on the side wall of the inner cavity. Specifically, during the pressing and lifting operations of the pressure rod 512, the positions of the second rope 509 and the third rope 511 inside or at the exit of the outlet tube 510 change. The two first rotating rods 5102 can prevent the two second ropes 509 from rubbing against the entrance of the outlet tube 510, and the second rotating rod 5103 can prevent the third rope 511 from rubbing when moving upward, thereby further improving the durability of the locking mechanism 5 and meeting the usage requirements in actual scenarios.

[0059] The working principle of the present invention is as follows:

[0060] When a mining transport device of this embodiment is used, the driver first needs to control the bidirectional drive mechanism 4 through the operating console 6. The core component of the bidirectional drive mechanism 4 is the first motor 401, which can realize the forward or backward movement of the device by forward or reverse rotation. When the driver operates the control switch 403 on the operating console 6, the first motor 401 is started, and the main gear 404 rotates accordingly. The main gear 404 transmits power to the transmission shaft 405 through the meshing sub-gear 406, and finally drives the wheel axle assembly 407 installed at the other end of the transmission shaft 405, so that the device moves forward or backward along the track.

[0061] During the driving process of the equipment, if it encounters an uneven track or a sloped section, the driver can control the locking mechanism 5 through the operating table 6, and use the upper clamping plate 502 and the lower clamping plate 503 to clamp the transmission shaft 405, thereby achieving deceleration control or complete locking of the equipment. In the design of the locking mechanism 5, the role of the friction part 504 is to increase the friction of the transmission shaft by contacting with the transmission shaft 405, thereby slowing down or stopping the movement of the equipment. When the equipment needs to stay in a specific position for a long time, the driver can press down the pressure rod 512 on the operating table 6, and by pulling the rope, the upper and lower clamping plates can tightly clamp the transmission shaft, and lock the pressure rod 512 through the limiting rod 514, so that the equipment is in a stable braking state to prevent sliding.

[0062] When loading and unloading materials such as ore, the bucket tipping mechanism 9 comes into play. The driver can drive the tension belt 906 on the lever bracket 901 by operating the second motor 905. One end of the tension belt 906 is connected to the bucket 3, and the other end is connected to the first shaft 903 of the second motor 905 by bypassing the second shaft 904. When the second motor 905 is started, the tension belt 906 pulls one end of the bucket 3 upward, and the bucket 3 flips accordingly, dumping the material out of the bucket 3. The design of the lever bracket 901 reduces the power demand of the second motor 905 by decomposing the vertical pulling force into vertical and horizontal components, making the operation more labor-saving, and reducing the overall weight of the equipment and the burden on the operating platform 6.
