Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, and in particular to an automatic cleaning device for a mining car. Background Art

[0002] A mine car is a narrow-gauge railway transport vehicle used to transport bulk materials such as coal, ore and waste rock in mines. It is generally towed by a locomotive or winch and is mainly used for rail transportation in underground tunnels, shafts and on the ground. It is the largest and most widely used type of transportation equipment in the mining industry.

[0003] During long-term transportation, a large amount of dust, rock fragments and other debris tend to accumulate inside the mine car, which affects the amount of material transported by the mine car. Therefore, the current practice is to use external cleaning equipment to regularly clean the mine car. However, this method usually requires the mine cars to be gathered together, which is time-consuming and labor-intensive, and the mine car transportation needs to be stopped during cleaning, which affects the transportation work; furthermore, once the debris accumulates too quickly during transportation, this regular cleaning method is often not timely enough. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an automatic cleaning device for a mine car in view of the above-mentioned technical deficiencies, which can be integrated with the car bucket to clean the mine car in time after unloading, with little impact on transportation efficiency and sufficient timely cleaning.

[0005] The technical solution adopted by the present invention is: to provide an automatic cleaning device for a mine car, comprising a cleaning control component arranged above the car bucket, and a travel adjustment component arranged outside the car bucket;

[0006] The cleaning control assembly comprises a mounting rod parallel to and spanning the top of the truck bucket along the width direction; a support rod is arranged parallel to the top of the mounting rod; extension rods are fixed to both ends of the support rod; the extension rod is arranged vertically downward and slides through the mounting rod; the lower ends of the two extension rods are connected by a control rod; the control rod corresponds to the parallel mounting rod; a plurality of pull ropes are sequentially connected to the length direction of the control rod; the upper ends of the pull ropes are respectively connected to the control rods, and the lower ends are respectively connected to hammer balls; the hammer balls correspond to the inner wall of the truck bucket; a power motor is fixed to the upper side of the mounting rod; a cam is fixed to the output end of the power motor; the cam is used to push the support rod to move up and down reciprocatingly; when the support rod moves up and down reciprocatingly, the hammer ball hammers the inner wall of the truck bucket reciprocatingly;

[0007] The walking adjustment assembly includes two adjusting screw rods arranged on the outside of the truck bed; the adjusting screw rods are arranged parallel to the length direction of the truck bed; the two ends of the adjusting screw rods are respectively connected to the two ends in the length direction of the truck bed through brackets; the adjusting screw rods rotate with the brackets; bases are respectively fixed at both ends of the mounting rod; the bases and the adjusting screw rods are threadedly connected one by one; when the bases are at the ends of the adjusting screw rods, the control rods are at the outside of the truck bed; a driving control mechanism for controlling the synchronous rotation of the two adjusting screw rods is arranged outside the truck bed.

[0008] To further optimize the technical solution, a control rod of an automatic cleaning device for a mine car is rotatably connected to an extension rod; the control rod is coaxially connected to an output shaft of an angle control motor fixed on the extension rod; a plurality of rope winding blocks are sequentially sleeved on the control rod along the length direction; the rope winding blocks are connected to the pull ropes in a one-to-one correspondence; a limiting groove for winding the pull rope is opened along the circumferential direction on the surface of the rope winding block; when the pull rope is wound until the beating balls are moved up to the outside of the car bucket, the number of turns of the pull ropes at different positions in the corresponding limiting grooves are all the same.

[0009] To further optimize the technical solution, the end of the mounting rod of an automatic cleaning device for a mine car is connected to the support rod by a tension spring.

[0010] To further optimize the technical solution, a hammering ball of an automatic cleaning device for a mine car is made of an iron core wrapped with rubber.

[0011] To further optimize the technical solution, a driving control mechanism of an automatic cleaning device for a mine car includes a driving motor fixed to the outer wall of the car bucket; a driving pulley is sleeved and fixed on the output end of the driving motor; driven pulleys are sleeved and fixed on the adjusting screw rod; the driving pulley and the driven pulley are connected by a transmission belt respectively.

[0012] The beneficial effects of the present invention are:

[0013] The cam is driven by a power motor to rotate, so that the support rod moves up and down, and the hammer ball hammers the inner wall of the bucket back and forth. The vibration impact effect can be used to make the accumulated materials and debris adhering to the inner wall of the bucket separate from the bucket. With the help of the bucket's own flipping, the detached debris can be easily separated from the bucket. This process can be carried out in time after the mine car is unloaded, reducing the impact on transportation efficiency.

[0014] The adjusting screw rod is arranged parallel to the length direction of the truck bucket, and the base is threadedly connected to the adjusting screw rod one by one. When the base is at the end of the adjusting screw rod, the control rod is at the outside of the truck bucket. By rotating the adjusting screw rod, the cleaning control assembly can be driven to move along the length direction of the truck bucket, so that the hammering ball can move from one end of the truck bucket to the other end, thereby realizing comprehensive cleaning of the inner wall of the truck bucket.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, an automatic cleaning device for a mine car comprises a cleaning control component arranged above the car bucket 1 and a travel adjustment component arranged outside the car bucket 1;

[0020] like Figure 1-2 As shown, the cleaning control assembly includes a mounting rod 2 parallel to and spanning the top of the truck bucket 1 in the width direction; a support rod 3 is arranged parallel to the top of the mounting rod 2; extension rods 4 are fixed to both ends of the support rod 3; the extension rod 4 is arranged vertically downward and slides through the mounting rod 2; the lower ends of the two extension rods 4 are connected by a control rod 5; the control rod 5 corresponds to the parallel mounting rod 2; a plurality of pull ropes 6 are connected in sequence along the length direction of the control rod 5; the upper ends of the pull ropes 6 are respectively connected to the control rods 5, and the lower ends are respectively connected to hammering balls 7; the hammering balls 7 correspond to the inner wall of the truck bucket 1; a power motor 8 is fixed to the upper side of the mounting rod 2; a cam 9 is fixed to the output end of the power motor 8; the cam 9 is used to push the support rod 3 to move back and forth up and down; when the support rod 3 moves back and forth up and down, the hammering balls 7 hammer back and forth on the inner wall of the truck bucket 1;

[0021] like Figure 1 As shown, the travel adjustment assembly includes two adjusting screw rods 10 arranged on the outside of the truck bucket 1; the adjusting screw rods 10 are arranged parallel to the length direction of the truck bucket 1; the two ends of the adjusting screw rod 10 are respectively connected to the two ends of the length direction of the truck bucket 1 through brackets 11; the adjusting screw rod 10 rotates with the bracket 11; the two ends of the mounting rod 2 are respectively fixed with bases 12; the base 12 is threadedly connected with the adjusting screw rod 10 in a one-to-one correspondence; when the base 12 is at the end of the adjusting screw rod 10, the control rod 5 is at the outside of the truck bucket 1; a driving control mechanism for controlling the synchronous rotation of the two adjusting screw rods 10 is arranged outside the truck bucket 1.

[0022] When the base 12 is at the end of the adjusting screw rod 10, the control rod 5 is outside the bucket 1. This state is the normal loading and unloading and transportation state of the bucket 1. At this time, the cleaning control component will not block the space above the bucket 1, so that the loading and unloading process is not affected.

[0023] After the bucket 1 is unloaded, if residual accumulated materials are found, the driving control mechanism drives the two adjusting screws 10 to rotate synchronously, moves the cleaning control assembly to the top of the bucket 1, and then drives the cam 9 to rotate by starting the power motor 8, so that the support rod 3 moves up and down reciprocatingly, and the beating ball 7 beats the inner wall of the bucket 1 reciprocatingly, and the accumulated materials and debris adhering to the inner wall of the bucket 1 can be separated from the bucket 1 by the effect of vibration impact. Then, as the adjusting screw 10 drives the cleaning control assembly to move along the length direction of the bucket 1, the beating ball 7 can move from one end of the bucket 1 to the other end, thereby achieving comprehensive beating of the inner wall of the bucket 1, and the accumulated materials at various places on the inner wall of the bucket 1 can be relatively completely separated from the bucket 1. Then, the bucket 1 itself is turned over to dump the debris out, thereby achieving convenient cleaning of the debris in the bucket 1. Of course, the driving control mechanism can drive the adjusting screw 10 to reverse, so that the beating ball 7 can achieve reciprocating vibration impact on the inner wall of the bucket 1.

[0024] In this technical solution, by installing the cleaning device together with the bucket 1 of the mine car, the bucket 1 can be cleaned at any time without stopping the transportation work, thereby reducing the impact on the transportation work. Moreover, the cleaning operation is convenient enough, saving time and labor. Compared with the traditional method of regularly gathering all the mine cars together for cleaning, the advantages are outstanding.

[0025] In addition, this solution uses a hammering and vibration method to separate the accumulated materials from the bucket 1 through vibration impact. Although the cleaning effect is slightly worse than the traditional water flushing method, it is impossible to ensure that the mine car is spotless in the working environment of the mine car, so the purpose of cleaning is not to clean the bucket 1, but to prevent the accumulated materials from occupying too much space in the bucket 1. Therefore, the hammering and vibration method is sufficient to meet the use requirements. The hammering and vibration method can not only clean the inside of the bucket 1, but also the debris attached to the outside of the bucket 1 can be vibrated off, and the cleaning is comprehensive. In addition, the vibration of the hammering ball 7 and the swing of the hammering ball 7 by the pull rope 6 can also separate the debris on its surface by impact, so it does not need to be cleaned separately, which further improves the convenience of use.

[0026] like Figure 1-2As shown, the control rod 5 is rotatably connected to the extension rod 4; the control rod 5 is coaxially connected to the output shaft of the angle control motor 13 fixed on the extension rod 4; a plurality of rope winding blocks 14 are sequentially sleeved on the control rod 5 along the length direction; the rope winding blocks 14 are connected one by one with the pull rope 6; a limiting groove 15 for winding the pull rope 6 is opened along the circumferential direction on the surface of the rope winding block 14; when the pull rope 6 is wound until the beating ball 7 is moved up to the outside of the truck bed 1, the number of turns of the pull rope 6 at different positions in the corresponding limiting groove 15 are all the same.

[0027] The angle control motor 13 can drive the control rod 5 to rotate, so that the rope winding block 14 rotates, and the pull rope 6 is respectively wound in the corresponding limiting groove 15, so that the hammering ball 7 is lifted above the bucket 1. Through this operation, the hammering ball 7 will not fall when the device is not in use, ensuring the stability and reliability of subsequent use. Because the bottom of the bucket 1 is sometimes not a plane, for example, the bottom of the bucket 1 of a side-turned mine car is a curved structure, such as Figure 1 As shown, the pull ropes 6 at different positions are sometimes of different lengths. In order to ensure that the hammering balls 7 at various locations can be pulled up above the truck bed 1 after the control lever 5 is rotated a certain number of times, the size of the rope block 14 must also be set accordingly according to the length of the pull rope 6 to ensure that the requirements are met.

[0028] like Figure 2 As shown, the ends of the mounting rod 2 and the support rod 3 are connected by tension springs 16. The tension of the tension springs 16 can ensure that after the support rod 3 is lifted up by the cam 9, when the high point of the cam 9 is separated from the support rod 3, the support rod 3 can fall smoothly.

[0029] The hammering ball 7 is made of a material with rubber wrapped around an iron core. The material of the hammering ball 7 makes it have enough weight to produce sufficient vibration impact, and can avoid rigid wear of the bucket 1 caused by impact.

[0030] The driving control mechanism includes a driving motor 17 fixed to the outer wall of the bucket 1; a driving pulley 18 is sleeved and fixed to the output end of the driving motor 17; driven pulleys 19 are sleeved and fixed to the adjusting screw rod 10; the driving pulley 18 and the driven pulley 19 are connected by a transmission belt 20. The driving motor 17 can be a reduction stepping motor, and the adjusting screw rod 10 drives the cleaning control component to move back and forth by switching between forward and reverse rotation of the driving motor 17.

[0031] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
