Description

Technical Field

[0001] The present invention relates to the technical field of ore ground transportation, in particular to a mining electromechanical ore ground transportation device and process. Background Art

[0002] In the mining industry, after ore is mined, it needs to be loaded into specialized mine cars. These narrow-gauge railway vehicles are used to transport bulk materials such as coal, ore, and waste rock within mines, typically towed by a locomotive or winch. Mine cars are categorized by their structure and unloading method into five main types: fixed mine cars, bucket mine cars, single-side curved track side-dump mine cars, bottom-dump mine cars, and shuttle mine cars. These mine cars are used on specialized tracks for transportation.

The pulley group is used for auxiliary unloading to achieve the purpose of saving effort.

[0018] 2. The anti-rollover component can prevent the mine car from rolling over when it is loaded with a lot of ore and encounters a fast downhill speed. Before the mine car moves, the hydraulic cylinder is started to drive the cross plate to move, and the plug rod fixed on the cross plate moves synchronously until the plug rod moves into the fixed cylinder.

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific examples. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as appropriate for specific applications.

[0028] A mining machine and electric ore surface transportation device, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the vehicle comprises a bucket 1, a base 101 and wheels 102. The bucket 1 is mounted on the upper portion of the base 101, and the wheels 102 are mounted on the left and right sides of the base 101. The base 101 is provided with an auxiliary unloading mechanism, which comprises a telescopic rod 2, a connecting plate 201, a mounting frame 202, a movable pulley 203, a connecting rope 204, a fixed pulley 205 and a first cylinder 206. The telescopic rod 2 is arranged on the side wall of the base 101, the connecting plate 201 is fixedly connected to the telescopic end of the telescopic rod 2, and the mounting frame 202 is rotatably connected to the vehicle bucket 1. On the outer wall, the movable pulley 203 is rotatably connected to the installation frame 202, the fixed pulley 205 is fixed to the connecting plate 201 through a U-shaped frame provided on the connecting plate 201, one end of the connecting rope 204 is fixed to the connecting plate 201 through a fixed frame, and passes around the movable pulley 203 and the fixed pulley 205 in turn, the first cylinder 206 is installed on the side wall of the base 101, the telescopic end of the first cylinder 206 is fixedly connected to the telescopic rod 2, wherein the telescopic rod 2 is formed by multiple connecting rods sleeved together, and the first cylinder 206 is arranged inside the telescopic rod 2.

[0029] When unloading, since the ore loaded in the bucket 1 is large and heavy, the auxiliary unloading mechanism can save the operator's effort in unloading. Before unloading, the first cylinder 206 is started to drive the telescopic rod 2 to move, and the telescopic rod 2 and the connecting plate 201 are extended to a certain distance. Then, the connecting rope 204 is pulled to drive the movable pulley 203 and the bucket 1 to move. As the bucket 1 rotates, the movable pulley 203 and the mounting frame 202 rotate accordingly. The cooperation of the movable pulley 203, the fixed pulley 205, the connecting rope 204 and the mounting frame 202 forms a labor-saving structure, which can pull the heavier bucket 1. Through the above technical solution, the cooperation of the telescopic rod 2 and the first cylinder 206 can retract and expand the connecting plate 201, the movable pulley 203 and the fixed pulley 205. They can be retracted during transportation, thereby reducing the occupied space, and expanded when unloading is required. The pulley group is used for auxiliary unloading to achieve the purpose of saving effort.

[0030] like Figure 2 As shown, a limiting assembly is provided between the base 101 and the truck bed 1, and the limiting assembly includes a fixed frame 3, an arc-shaped plate 301, a limiting column 302 and a limiting hole 303. The fixed frame 3 is fixedly connected to the surface of the base 101, the arc-shaped plate 301 is symmetrically fixedly connected to the front and rear side walls of the truck bed 1, the limiting column 302 is fixedly connected to the surface of the arc-shaped plate 301, and the limiting holes 303 are evenly arranged on the upper end surface of the fixed frame 3, and the limiting holes 303 and the limiting columns 302 cooperate with each other.

[0031] The limit assembly provided can limit the bucket, thereby further ensuring the stability of the bucket during movement. Through the cooperation of the limit column 302 and the limit hole 303, the moving direction of the mine car is limited during the movement of the mine car, thereby avoiding the mine car from rolling over to a certain extent.

[0032] like Figure 4 、 Figure 5 and Figure 6 As shown, a locking assembly is provided between the base 101 and the truck bed 1, and the locking assembly includes a second cylinder 4, a rocker 401, a connecting rod 402, a slide 403, a positioning column 404 and a spring 405. The second cylinder 4 is fixedly mounted on the surface of the base 101 through a limit frame, and the output end of the second cylinder 4 is rotatably connected to the rocker 401, the connecting rod 402 is fixedly connected to the opposite inner walls of the base 101, the rocker 401 and the connecting rod 402 are rotatably connected, the end of the rocker 401 is rotatably connected to the slide 403, and the slide 403 is slidably connected between the opposite inner walls of the base 101, the spring 405 is arranged in the base 101 and fixedly connected to the slide 403, the positioning column 404 is fixedly connected to the surface of the slide 403, and a positioning hole cooperating with the positioning column 404 is provided at the bottom of the truck bed 1.

[0033] Before unloading, the second cylinder 4 is started first to drive the rocker 401 to rotate upward. The rocker 401 rotates around the connecting rod 402 under the action of the connecting rod 402. The rocker 401 further drives the slide plate 403 to move downward. At this time, the spring 405 is compressed, and the slide plate 403 drives the positioning column 404 fixed thereto to move, so that the positioning column 404 is not plugged into the bucket 1, and the unloading can be carried out through the auxiliary unloading mechanism. After unloading is completed, the second cylinder 4 is started to drive the rocker 401 to rotate downward. The rocker 401 rotates around the connecting rod 402 under the action of the connecting rod 402. The rocker 401 further drives the slide plate 403 to move upward. At this time, the spring 405 returns to its initial state, so that the positioning column 404 and the bucket 1 are plugged into each other to achieve the positioning of the bucket 1, and the spring 405 limits the slide plate 403.

[0034] like Figure 7 As shown, a reduction assembly is provided between the base 101 and the wheel 102, and the reduction assembly includes a transmission box 5, a motor 501, a screw rod 502, a moving block 503, a transmission rod 504, a moving frame 505 and a clamping arc 506. The transmission box 5 is fixedly connected to the right side wall of the base 101, the motor 501 is installed on the top of the transmission box 5, the output end of the motor 501 is fixedly connected to the screw rod 502, a slide groove is provided inside the transmission box 5, the screw rod 502 is rotatably connected in the slide groove, the moving block 503 is slidably connected in the slide groove, the moving block 503 and the screw rod 502 are threadedly connected, the transmission rod 504 is symmetrically mounted on the moving block 503 for rotation front and back, the other end of the transmission rod 504 is rotatably connected to the moving frame 505, the moving frame 505 is slidably connected to the transmission box 5, the moving frame 505 is fixedly connected to the clamping arc 506, and the clamping arc 506 cooperates with the right wheel 102.

[0035] When the mine car encounters a fast downhill speed, it is easy to stall and roll over. The deceleration component provided can reduce the speed of the mine car. The starting motor 501 drives the screw rod 502 to rotate, and the screw rod 502 drives the moving block 503 threadedly connected thereto to move. The moving block 503 further drives the transmission rod 504 to rotate, and the transmission rod 504 pushes the moving frame 505 to move forward. The clamping arc 506 fixedly connected to the moving frame 505 finally squeezes the wheel 102, thereby achieving the purpose of braking, reducing the moving speed of the mine car and preventing rollover.

[0036] like Figure 5 and Figure 7 As shown, a strip groove is provided inside the transmission box 5, and the moving frame 505 is slidably connected in the strip groove. The strip groove has a limiting effect on the moving frame 505, ensuring that the moving frame 505 moves along a straight line. Two sets of bow plates are fixedly connected to the base 101, and four wheels 102 are rotatably connected to the two ends of the bow plates.

[0037] like Figure 1As shown, an anti-rollover assembly is provided on the outside of the truck bed 1, and the anti-rollover assembly includes a support column 6, a fixed rail 601, a movable plate 602, a hydraulic cylinder 603, a cross plate 604, an insertion rod 605 and a fixed cylinder 606. The anti-rollover assembly is arranged on both sides of the track, wherein the support column 6 is installed on the ground, the end of the support column 6 is connected to the fixed rail 601, the movable plate 602 is slidably connected in the fixed rail 601, the hydraulic cylinder 603 is installed on the surface of the movable plate 602, the cross plate 604 is fixedly connected to the telescopic end of the hydraulic cylinder 603, the insertion rod 605 is fixedly connected to the surface of the cross plate 604, and the fixed cylinder 606 is respectively connected to the top of the four corners of the truck bed 1, and the insertion rod 605 and the fixed cylinder 606 are plugged in.

[0038] The anti-rollover assembly set up can prevent the mine car from overturning when the mine car is loaded with a lot of ore and encounters a fast downhill speed. Before the mine car moves, the hydraulic cylinder 603 is started to drive the cross plate 604 to move, and the insertion rod 605 fixed on the cross plate 604 moves synchronously until the insertion rod 605 moves into the fixed cylinder 606. At this time, due to the connection between the insertion rod 605 and the fixed cylinder 606, the mine car can avoid rolling over when moving.

[0039] The present invention also provides a mining machine-electric ore surface transportation process, comprising the following steps:

[0040] S1: Loading: Use a mining machine to mine ore in the mine and load it into the truck bed 1.
