Description

Technical Field

[0001] The present invention belongs to the technical field of coal mine conveying, and specifically relates to a mine wire rope traction conveyor device with multi-angle turning. Background Art

[0002] Belt conveyors are the most important bulk material conveying and loading / unloading equipment, and are widely used in industrial fields such as mines, metallurgy, building materials, chemical industry, electric power, and food processing. In coal mining, the coal mined in the mine is mainly transported to the ground through belt conveyors.

[0003] After retrieval, a patent application with the application number CN202311080998.6 discloses a coal mine conveyor for coal mining. Through the settings of support bars, drive components, moving components, flipping components, water tanks, elastic components, dispersing components, transmission components, and extrusion components, the coal is dumped onto the upper end of the belt for conveying. First, the electric telescopic rod is started, so that the moving plate and the extrusion block move reciprocally, thereby causing the moving bar to move as well. Through the elasticity of spring A, the fixed block and the fixed strip can continuously bounce, so as to be able to disperse coal lumps. When the moving plate moves, it can drive the cleaning roller to brush over the outer surface of the belt. Through motor A, the replacement use of the two groups of cleaning rollers can be realized, the cleaning of the belt can be achieved, the service life of the belt can be increased, and thus the mining cost can be reduced.

[0004] A patent application with the application number CN202110818648.X discloses a belt conveyor for coal mines. By adding a first hinge between the first bearing and the second bearing and cooperating with a spacing adjustment mechanism, the transportation efficiency is improved; the first piston cylinder is used to spray water mist reciprocally to extend the service life of the equipment; the residual coal powder and coal cinder on the belt are scraped off by the curved scraper and then collected by the material receiving frame and transported to the discharge place, improving the quality and efficiency of coal transportation.

[0005] A patent application with the application number CN202210508996.1 discloses a belt conveyor for coal mines. By setting the belt into several sections, the operator can select the number of belt sections to be installed according to the actual use length, and install the belt through the fastening components. Then, after being powered on, the transmission components transmit power to the belt, which can improve the use range of the belt, and any damaged section of the belt can be immediately disassembled and a new belt can be replaced in time to ensure the normal operation of the conveyor.

[0006] The turning belt of the existing belt conveyor is fixed, and it can only turn left and right twice, and there cannot be too many up and down turns. Moreover, the belt support cannot move. The transportation roadway of the gently inclined coal seam working face in the coal mine can only be driven in a fixed direction, resulting in a high and low transportation in the working face. When there are folds in the coal seam strike, the belt cannot be installed in the transportation roadway of the working face, especially in the transportation roadway of the steeply inclined coal seam, which cannot be driven in a fixed direction; mechanized mining cannot be realized, and the roadway requires the integration of machine tracks, resulting in a large cross-section, increased difficulty and safety costs.

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] As Figures 1 to 4 shown, a mine steel - wire - rope traction conveyor device with multi - angle turning described in an embodiment of the present invention includes a plurality of main supports 1 and two transmission structures; the plurality of main supports 1 are uniformly fixed along the mine transportation lane; a pair of cross - frames 2 are arranged on each main support 1; a pair of U - shaped seats 3 are bolted to the bottom surfaces of the two cross - frames 2, and the U - shaped seats 3 can change angles; clamping wheels 4 are rotatably installed at both ends of the bottom of the U - shaped seats 3; the two transmission structures are respectively located at both ends of the mine transportation lane; the transmission structure includes a main shaft 5; the main shaft 5 is rotatably installed on the main support 1 at the end of the mine transportation lane; a pair of driving wheels 6 are bolted to the outer ring of the main shaft 5; steel - wire ropes 7 are sleeved on the outer rings of the two driving wheels 6 at the same end of the two main shafts 5; a conveyor belt 8 is fixedly connected between the two steel - wire ropes 7; the steel - wire ropes 7 pass through between the two clamping wheels 4 at the bottom of the U - shaped seats 3; a driving structure is arranged on one main shaft 5, and the driving structure is used to drive the main shaft 5 to rotate; A driving motor 9 is arranged on one side of the middle of one main shaft 5; the driving motor 9 is fixedly connected to the main support 1 through a bracket; pulley 10 are fixedly connected to the output shaft of the driving motor 9 and the outer ring of the main shaft 5; a transmission belt 11 is sleeved on the outer rings of the two pulleys 10; The turning belt of the existing belt conveyor is fixed, with only two left and right turns possible, not many up and down turns, and the belt support cannot move either. In the transportation roadway of the gently inclined coal seam working face in a coal mine, only directional tunneling can be carried out, resulting in a high-low situation in the working face transportation. When there are folds in the coal seam strike, the belt cannot be installed in the working face transportation roadway, especially in the transportation roadway of the steeply inclined coal seam where directional tunneling cannot be carried out. Mechanized mining cannot be achieved, and the roadway requires the integration of machine tracks, resulting in a large cross-section, increased difficulty, and safety costs. To solve such problems, the conveyor device of this application is designed. In this embodiment, the conveyor belt 8 is made of a wire mesh woven into an inner rib and attached with soft rubber, and the surface of the conveyor belt 8 has a layer of flame-retardant material. During operation, the main brackets 1 are evenly and fixedly distributed along the mine transportation roadway, and two driving structures are arranged at both ends of the mine transportation roadway. Since the two steel wire ropes 7 pass through multiple pairs of pulley wheels 4 on both sides in sequence, the two steel wire ropes 7 extend along the mine transportation roadway. When encountering a turning point of the mine transportation roadway, by controlling and adjusting the angle of the U-shaped seat 3, the deflection angle of the pulley wheels 4 is adjusted, and the bending angle of the steel wire rope 7 is controlled and adjusted, thereby controlling and adjusting the bending angle of the conveyor belt 8. At the same time, since the steel wire rope 7 is clamped by each pair of pulley wheels 4, the driving motor 9 drives the belt pulley 10 to rotate. Through the transmission of the transmission belt 11 and the belt pulley 10, the driving wheel 6 is driven to rotate, driving the steel wire rope 7 to move. The steel wire ropes 7 on both sides move, driving the conveyor belt 8 to move. Since the traction force is provided by the steel wire rope 7, and the steel wire rope 7 drives the conveyor belt 8 to move from both sides of the conveyor belt 8, direct traction movement of the conveyor belt 8 is avoided. The conveyor belt 8 carries coal mines and moves along with the steel wire rope 7 for conveying. The left and right turns and up and down turns of the steel wire rope 7 can be flexibly adjusted by the pulley wheels 4, enabling the conveyor belt 8 to also make left and right turns and up and down turns, so that the conveyor device can adapt to complex mine transportation roadways and reduce the conveying difficulty of coal mines.

[0025] As Figure 2 、 Figure 3 、 Figure 7 and Figure 8 shown, the cross frame 2 and the main bracket 1 are hinged through a hinge seat 12; a first telescopic rod 13 is arranged between the bottom surface of the cross frame 2 and the main bracket 1; both ends of the first telescopic rod 13 are also hinged to the cross frame 2 and the main bracket 1 through the hinge seat 12; a second telescopic rod 14 is arranged between the top surface of the cross frame 2 and the main bracket 1; both ends of the second telescopic rod 14 are also hinged to the cross frame 2 and the main bracket 1 through the hinge seat 12. The structures of the first telescopic rod 13 and the second telescopic rod 14 are the same; both the first telescopic rod 13 and the second telescopic rod 14 include a first internal threaded cylinder 15; both ends inside the first internal threaded cylinder 15 are threadedly installed with first threaded rods 16; one end of the first threaded rod 16 away from the first internal threaded cylinder 15 is fixedly connected to a square iron with a round hole opened thereon. Due to the different sidewall inclination angles of the mine transportation roadway, the installation angle of the main support 1 will also be different accordingly, and then it is necessary to control and adjust the angle of each cross frame 2. When installing the cross frame 2, connect and install the cross frame 2 to the main support 1 through the hinge seat 12, and at the same time rotate the cross frame 2 to adjust the angle; according to the angle of the cross frame 2 and the distance between the main supports 1, adjust the lengths of the first telescopic rod 13 and the second telescopic rod 14, that is, rotate the first threaded rods 16 at both ends of the first internal threaded cylinder 15. Since the first threaded rods 16 are in threaded fit with the internal threads of the first internal threaded cylinder 15, the lengths of the first telescopic rod 13 and the second telescopic rod 14 are adjusted; install the first telescopic rod 13 between the lower part of the cross frame 2 and the main support 1, and install the second telescopic rod 14 between the upper part of the cross frame 2 and the main support 1; two stable triangular structures are formed among the first telescopic rod 13, the second telescopic rod 14, the cross frame 2 and the main support 1, and the cross frame 2 is fixed and locked; thus, it is convenient to control and adjust the angle of the cross frame 2, and at the same time, the firmness of the cross frame 2 is ensured.

[0026] As Figure 2 、 Figure 3 and Figure 9 shown, the cross frame 2 includes a fixed cross bar 17 and an extending cross bar 18; one end of the fixed cross bar 17 close to the extending cross bar 18 is fixedly connected to a sleeve 19; one end of the extending cross bar 18 close to the fixed cross bar 17 is fixedly connected to a sliding rod 20; the sliding rod 20 is slidably matched with the sleeve 19; a plurality of matching positioning bolt holes 21 are evenly opened on the sliding rod 20 and the sleeve 19; bolts can be installed in the positioning bolt holes 21. During operation, adjust by sliding the sliding rod 20 in the sleeve 19, and then use bolts to pass through the positioning bolt holes 21 to lock and fix the sliding rod 20 and the sleeve 19, control and adjust the length of the extending cross bar 18 extending from the fixed cross bar 17, and then control and adjust the length of the cross frame 2, control and adjust the distance between the two U-shaped seats 3 on both sides, so as to control and adjust the distance between the two steel wire ropes 7, and then control and adjust the distance between both sides of the conveyor belt 8. Moreover, since the driving wheel 6 is bolted to the outer ring of the main shaft 5, the driving wheel 6 can adjust its position to adapt to the position of the steel wire rope 7. When the conveyor belt 8 conveys coal, increase the length of the cross frame 2, so that the distance between the two U-shaped seats 3 on both sides increases, the distance between the two steel wire ropes 7 increases, and then the distance between both sides of the conveyor belt 8 increases, thus facilitating the loading of coal and improving the conveying efficiency of coal. When the conveyor belt 8 returns, the length of the cross frame 2 is reduced, so that the distance between the U-shaped seats 3 on both sides is reduced, the distance between the two steel wire ropes 7 is reduced, and then the distance between the two sides of the conveyor belt 8 is reduced, thus reducing the volume when the conveyor belt 8 returns, and then facilitating the passage of staff and equipment.

[0027] As Figures 5 to 6 shown, the bottoms of both ends of the U-shaped seat 3 are rotating shafts; a bearing is arranged on the inner ring of the idler wheel 4; the bearing inside the idler wheel 4 is sleeved on the outer ring of the rotating shaft of the U-shaped seat 3; By setting the bottoms of both ends of the U-shaped seat 3 as rotating shafts and arranging bearings on the inner ring of the idler wheel 4, the frictional resistance when the idler wheel 4 rotates is effectively reduced, and the smoothness of the movement of the steel wire rope 7 is improved.

[0028] As Figure 1 and Figure 10 shown, a fixing rod 22 is bolted between the ends of adjacent cross frames 2 away from the main support 1; fixing brackets 23 are rotatably installed at both ends of the main shaft 5; the fixing brackets 23 are hinged to the main support 1 through hinge seats 12; a first telescopic rod 13 is also arranged between one of the fixing brackets 23 close to the main shaft 5 and the main support 1; The fixing rod 22 includes a second internal thread cylinder 24; second threaded rods 25 are threadedly installed at both ends inside the second internal thread cylinder 24; bolts are vertically arranged at the ends of the second threaded rods 25 away from the second internal thread cylinder 24, and nuts are threadedly installed on the bolts of the second threaded rods 25; During operation, the adjacent cross frames 2 are fixedly connected by the arranged fixing rod 22, thereby improving the stability of the cross frame 2 and further improving the stability of coal mine conveying; and according to the distance between two adjacent cross frames 2, the length of the fixing rod 22 is controlled and adjusted, that is, the second threaded rods 25 at both inner sides of the second internal thread cylinder 24 are rotated. Since the second threaded rods 25 are in threaded cooperation with the second internal thread cylinder 24, the length of the fixing rod 22 is adjusted, and then it is convenient for the fixing rod 22 to adapt to the distance between two adjacent cross frames 2; The main shaft 5 is installed on the main support 1 through the arranged fixing brackets 23, and the angle of the main shaft 5 is controlled and adjusted through the first telescopic rod 13 to facilitate driving the steel wire rope 7 to move.

[0029] As Figure 4 and Figure 11As shown in the figure, a plurality of anti - detachment mechanisms are provided on one side of the driving wheel 6 away from the driving structure; the anti - detachment mechanism includes a hollow seat 26; the hollow seat 26 is fixedly connected to the fixed bracket 23; a sliding column 27 is slidably installed inside the hollow seat 26; a tension spring 28 is fixedly connected between the sliding column 27 and the hollow seat 26; a pressure wheel 29 is rotatably installed at one end of the sliding column 27 away from the hollow seat 26; the pressure wheel 29 cooperates with the driving wheel 6, and the pressure wheel 29 is slidably matched with the steel wire rope 7; During operation, the elastic force of the tension spring 28 pulls the sliding column 27 to have a tendency to slide into the interior of the hollow seat 26. The sliding column 27 drives the pressure wheel 29 to have a tendency to approach and contact the driving wheel 6. The pressure wheel 29 cooperates with the driving wheel 6 to clamp the steel wire rope 7, thereby reducing the situation that the steel wire rope 7 falls off from the driving wheel 6 when the driving wheel 6 drives the steel wire rope 7 to move; and due to the downward pressure of the pressure wheel 29, the driving wheel 6 can effectively drive the steel wire rope 7 to move, improving the consistency of the moving speeds of the two steel wire ropes 7, and thus improving the stability of the movement of the conveyor belt 8.

[0030] As Figure 4 As shown in the figure, a supporting wheel 30 is fixedly connected to one side of a pair of driving wheels 6 close to each other; the inner ring of the supporting wheel 30 is fixedly connected to the outer ring of the main shaft 5; the outer ring of the supporting wheel 30 is slidably matched with the inner rings on both sides of the conveyor belt 8; During operation, when the steel wire rope 7 passes through the driving wheel 6, it drives the conveyor belt 8 to pass between the two driving wheels 6 on both sides. By arranging the supporting wheel 30 to lift and support both sides of the conveyor belt 8, the pulling force of the conveyor belt 8 on the two steel wire ropes 7 on both sides is reduced, and further reduces the situation that the steel wire rope 7 falls off from the driving wheel 6.

[0031] Working principle: The main brackets 1 are evenly and fixedly distributed along the mine transportation lane. The cross - frame 2 is connected and installed to the main bracket 1 through the hinge seat 12, and at the same time, the cross - frame 2 is rotated to adjust the angle; according to the angle of the cross - frame 2 and the spacing of the main brackets 1, the lengths of the first telescopic rod 13 and the second telescopic rod 14 are adjusted, that is, the first threaded rods 16 at both ends of the first internal threaded cylinder 15 are rotated. Since the first threaded rods 16 are in internal - thread fit with the first internal threaded cylinder 15, the lengths of the first telescopic rod 13 and the second telescopic rod 14 are adjusted; the first telescopic rod 13 is installed between the lower part of the cross - frame 2 and the main bracket 1, and the second telescopic rod 14 is installed between the upper part of the cross - frame 2 and the main bracket 1; two stable triangular structures are formed among the first telescopic rod 13, the second telescopic rod 14, the cross - frame 2 and the main bracket 1 to fix and lock the cross - frame 2; Moreover, the main shaft 5 is installed on the main bracket 1 through the fixed bracket 23 provided, and the angle of the main shaft 5 is controlled and adjusted by the first telescopic rod 13. The two transmission structures are arranged at both ends of the mine transportation lane; The elastic force of the tension spring 28 pulls the sliding column 27 to have a tendency to slide towards the inside of the hollow seat 26. The sliding column 27 drives the pressing wheel 29 to have a tendency to approach and contact the driving wheel 6. The pressing wheel 29 cooperates with the driving wheel 6 to clamp the steel wire rope 7. And due to the downward pressure of the pressing wheel 29, the driving wheel 6 can effectively drive the steel wire rope 7 to move, improving the consistency of the moving speeds of the two steel wire ropes 7. Since the two steel wire ropes 7 pass through multiple pairs of idler wheels 4 on both sides in sequence, the two steel wire ropes 7 extend along the mine transportation lane. When encountering a turning point of the mine transportation lane, by controlling and adjusting the angle of the U-shaped seat 3, the deflection angle of the idler wheel 4 is adjusted, and the bending angle of the steel wire rope 7 is controlled and adjusted, thereby controlling and adjusting the bending angle of the conveyor belt 8. At the same time, since the steel wire rope 7 is clamped by each pair of idler wheels 4, the driving motor 9 drives the pulley 10 to rotate. Through the transmission of the transmission belt 11 and the pulley 10, the driving wheel 6 is driven to rotate, driving the steel wire rope 7 to move. The steel wire ropes 7 on both sides move, driving the conveyor belt 8 to move. Since the traction force is provided by the steel wire rope 7 and the steel wire rope 7 drives the conveyor belt 8 to move from both sides of the conveyor belt 8, the direct traction movement of the conveyor belt 8 is avoided. The conveyor belt 8 carries the coal mine and moves along with the steel wire rope 7 for transportation. The idler wheels 4 can flexibly adjust the left and right turns and the up and down turns of the steel wire rope 7, enabling the conveyor belt 8 to also make left and right turns and up and down turns, so that the conveyor device can adapt to the complex mine transportation lane and reduce the transportation difficulty of the coal mine.
