Description

Technical Field

[0001] The invention belongs to the technical field of coal mining face conveying devices, and relates to a scraper conveying and crushing integrated platform, in particular to a self-moving scraper conveying and crushing integrated platform. Background Art

[0002] The conventional standard supporting equipment for the rear road transportation of the coal mining working face is: a transfer machine and a crusher with a belt for continuous transfer and transportation, thereby ensuring the safe and efficient production of the working face. However, due to the limitations of the working face layout, the specifications of the rear tunnel, and the specifications of the lower chute, the large parts of the transfer machine are returned, installed, moved daily, and dismantled and withdrawn. This brings great difficulties and challenges, especially when the lower chute is irregular, the tunnel specifications are small, the tunnel pressure is high, and the tunnel converges and deforms quickly. When problems such as this occur, the transfer machine will not be able to achieve regular movement and cannot meet the requirements of safe transportation and safe pedestrians. This makes it impossible to install an integral loader and crusher near the working face, and the equipment needs to be installed outside the working face. When the working face encounters ballast, it needs to be stopped for manual crushing before transportation. Frequent shutdowns for crushing large coal blocks will seriously affect production. Therefore, conventional supporting equipment can no longer meet the needs of safe and efficient production under the current situation. Summary of the invention

[0003] The purpose of the present invention is to provide a self-moving scraper conveying and crushing integrated platform to solve the technical problems existing in the prior art that the rear-road transportation equipment of the coal mining face cannot be moved normally, cannot meet the requirements of safe transportation and pedestrian safety, and even affects production.

[0004] To achieve the above purpose, the specific technical solutions of the present invention are as follows:

[0006] The head of the scraper conveyor is set at the end where the horizontal connecting platform and the belt conveyor are connected, and the tail of the scraper conveyor extends from the horizontal connecting platform, the slope connecting platform and the outside of the slope connecting platform in sequence;

[0007] The front and rear of the support leg group B are fixed by an I-beam, the tail mounting seat of the belt conveyor is fixed on the I-beam, the tail rotating shaft of the belt conveyor is rotatably arranged on the tail mounting seat, and the conveying plane of the belt conveyor is lower than the table surface of the horizontal connecting table;

[0008] There are two pickaxes, which are symmetrically arranged on the I-beams on both sides of the horizontal connecting platform. The pickaxes are connected to the emulsification pump station and supply liquid through the emulsification pump station. One end of the pickaxe is connected to the I-beam and the other end is fixed.

[0009] The bottom and top of the slope of the slope-starting connecting platform are slope changing points. The bottom of the slope is a groove tangent to two sides thereof, and the top of the slope is a convex groove tangent to two sides thereof.

[0010] The support leg group A includes multiple pairs of support legs of different heights. The multiple pairs of support legs are evenly arranged in order from low to high and symmetrically distributed on both sides of the slope connecting platform. The interval between each pair of support legs is less than 500 mm. The support legs on each side of the slope connecting platform are connected front and back by equal-strength anchor rods.

[0011] The support leg group B includes multiple pairs of support legs, which are symmetrically distributed on the left and right sides of the horizontal connecting platform, and the interval between each pair of support legs is in the range of 600-1500mm.

[0012] A bottom anchor is driven on the tunnel floor 30-50m away from the tail of the belt conveyor. One end of the pick is fixed on the bottom anchor.

[0020] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 3 As shown, this embodiment provides a self-moving scraper conveying and crushing integrated platform, which includes a slope connection platform 2, a horizontal connection platform 1 and a pull pick 3. The slope connection platform 2 is arranged on the support leg group A 4 by connecting bolts, and the angle between it and the horizontal plane is 5-20°. In this embodiment, it is preferably 15°. The horizontal connection platform 1 is arranged on the support leg group B 7 by connecting bolts and is parallel to the horizontal plane. One end of the horizontal connection platform 1 is connected to the upper end of the slope connection platform 2, and the other end is connected to the belt conveyor 5. The ends of the support leg group A 4 and the ends of the support leg group B that are close to each other are fixedly connected.

[0022] The scraper conveyor 6 is arranged on the slope connection platform 2 and the horizontal connection platform 1. The head 61 of the scraper conveyor is arranged at one end of the horizontal connection platform 1 connected with the belt conveyor 5, and is connected to the horizontal connection platform 1 through bolts, channel steel and other intermediate parts. The tail 62 of the scraper conveyor extends from the horizontal connection platform 1 and the slope connection platform 2 to the outside of the slope connection platform 2. The length of the scraper conveyor 6 is generally selected between 15 and 60 meters, which is determined according to the specific situation. It should not be too long. If it is too long, it is easy to be unable to pull or the chain 15 is broken, and the safety of pulling and moving cannot be guaranteed.

[0023] In order to improve the stability of the horizontal connection platform 1, the front and rear of the support leg group B 7 are fixed by an I-beam 8, the tail mounting seat 9 of the belt conveyor 5 is fixed on the I-beam 8 and located below the horizontal connection platform 1, and the tail rotating shaft 10 of the belt conveyor 5 is rotatably arranged on the tail mounting seat 9, and the conveying plane of the belt conveyor 5 is lower than the table surface of the horizontal connection platform 1;

[0024] In order to improve the stability of the platform's self-movement during the process of pulling the platform, the number of pull picks 3 in this embodiment is two, which are symmetrically arranged on the I-beams 8 on both sides of the horizontal connecting platform 1. Preferably, the length of the pull pick 3 is 1.6 meters. The pull pick 3 is connected to the emulsification pump station and supplied with liquid through the emulsification pump station. One end of the pull pick 3 is connected to the I-beam 8, and the other end is fixed.

[0025] In this embodiment, the scraper conveyor 6 and the belt conveyor 5 are arranged on the slope connection platform 2 and the horizontal connection platform 1 to form a linkage-capable whole. When the scraper conveyor 6 and the belt conveyor 5 need to be pulled, it is only necessary to control the emulsification pump station to supply or return liquid to the pick 3, so that the pick 3 can be used to drag the support leg group B 7, and the support leg group A 4, the horizontal connection platform 1, the slope connection platform 2, the tail of the belt conveyor 5, and the scraper conveyor 6 connected thereto to move the machine in a linkage manner. There is no need to be limited by the working face layout, the specifications of the rear tunnel, and the specifications of the lower chute, which reduces the difficulty coefficient in the process of transporting and installing large items, solves the problem of rear-road transportation and crushing of irregular high-pressure coal mining working faces in complex working faces, and ensures safe and efficient production.

[0026] Furthermore, the bottom and top of the slope of the slope connecting platform 2 are slope change points. When the scraper moves in the chute of the scraper conveyor 6, if the chute is straight-line sloped or straight-line downhill, the running resistance of the scraper at the slope change point will increase abnormally, and accidents such as chain breakage and scraper falling out of the chute will frequently occur during use. Therefore, in this embodiment, the bottom of the slope is a groove 12 tangent to both sides thereof, and the top of the slope is a convex groove 13 tangent to both sides thereof. This arrangement can greatly reduce the occurrence of such accidents, thereby ensuring that the scraper conveyor 6 can better perform transportation services to assist production.

[0027] Furthermore, the support leg group A 4 includes multiple pairs of support legs with different heights, and the multiple pairs of support legs are evenly arranged in order from low to high and symmetrically distributed on both sides of the slope connecting platform 2. The interval between each pair of support legs is less than 500 mm. The specific interval is determined according to actual conditions and is not specifically limited in this embodiment. The support legs on each side of the slope connecting platform 2 are connected front and back by equal-strength anchor rods. In this embodiment, two of the support legs are selected to be connected front and back by equal-strength anchor rods.

[0028] Furthermore, the support leg group B 7 in this embodiment includes multiple pairs of support legs, and the multiple pairs of support legs are symmetrically distributed on the left and right sides of the horizontal connecting platform 1. Since the tail of the belt conveyor 5 needs to be set between the support legs B, no specific restrictions are made on the support legs B in this embodiment. The horizontal connecting platform 1 can be kept level. The interval between each pair of support legs is 600-1500mm. The staff can flexibly set it according to the on-site conditions. No specific restrictions are made in this embodiment.

[0029] In order to provide a fixing point and a supporting point for the pick 3, in this embodiment, a bottom anchor 14 is installed on the tunnel floor 30-50m away from the tail of the belt conveyor 5. One end of the pick 3 is fixed on the bottom anchor 14. A chain 15 is fixed on the I-beam 8 behind the tail mounting seat 9 of the belt conveyor 5. The other end of the chain 15 is connected to the other end of the pick 3 through a steel cable 16. When the pick 3 pulls the platform, the pick 3 contracts, and the steel cable 16 drags the chain 15 to drive the I-beam 8 to move, thereby driving the support leg group B 7 and other equipment to move.

[0030] At the same time, in order to solve the defect that the original scraper conveyor 6 cannot be matched with the crusher to realize the crushing function, in this embodiment, transfer machine troughs 17 are provided at both ends of the crusher. The crusher is arranged on the body of the horizontal scraper conveyor 6 close to the groove 12 side through the transfer machine trough 17. The two are perfectly combined through the transfer machine trough 17 to realize the ballast breaking function.

[0031] The technical solution in this embodiment was tried out on the 11216-2 working face and the 11298 working face respectively. During use, the transportation was safe and reliable, which improved the overall production efficiency of the coal mining system and provided ideas for solving practical problems for the design and installation of similar working faces in the next step.
