Description

TECHNICAL FIELD

[0001] The present application relates to the field of conveying equipment, in particular to a high-efficiency conveying equipment for mining. BACKGROUND

[0002] The transportation of ore is a key link to ensure that the production activities of the mine can be carried out stably and continuously, especially when the distance between the ore mining site and the conveying destination, such as the ore dressing plant or the warehouse, is relatively far, the freshly mined ore needs to be transported away in time, therefore the ore transportation equipment will directly affect the scale and efficiency of the mining activities. In addition to common vehicles, some mines also use large-span long-distance conveying belts as conveying equipment.

[0003] The related technology can refer to the Chinese patent application with publication number CN118811375B, which discloses a long-distance whole lifting ton bag conveyor, including a rack, a pushing mechanism is arranged at one end of the inner side of the rack, the pushing mechanism includes a first transmission shaft, the first transmission shaft is rotationally connected with the rack, and a first rotating wheel is fixedly connected with the end of the first transmission shaft away from the rack. When the tension of the conveying belt is reduced or too large, the tension of the conveying belt is adjusted by the pushing mechanism, and after the adjustment is completed, the pushing mechanism is locked by the locking mechanism to prevent the problem that the tension of the adjusted conveying belt becomes larger or smaller again.

[0004] In view of the related technology in the above, in order to improve the stability and continuity of ore conveying, the conveying route usually avoids being connected by multiple conveying devices as much as possible when conveying ore over a long distance, but due to the restriction of geographical environment, such as lakes, mountains or mine tunnels, hills and other natural geological restrictions, it is usually difficult to keep the conveying route straight, so the conveying equipment is required to have a bendable adjustment function. The conveying equipment usually includes a rack and a belt, and the bending and twisting of the rack is relatively easy to achieve, but although the belt has deformable properties, its deformation amount in the width direction is limited, and a large turning radius is usually required when a large angle bending is achieved. The width direction of the belt is the direction that needs to be bent horizontally, and if the belt is provided with a sufficient turning radius, the conveying route will be extended, which will affect the conveying efficiency of the ore.

DETAILED DESCRIPTION

[0030] The application is further described in detail below in combination with all the drawings.

[0031] The embodiment of the application discloses a high-efficiency conveying device for mining.

[0032] Embodiment 1 Referring to Figure 1 and Figure 2 A high-efficiency conveying device for mining includes a rack 1 and a belt 2 arranged along the length direction of the rack 1. The rack 1 includes alternately arranged upper supports 11 and lower supports 12, and is further provided with a plurality of groups of conveying rollers 13 arranged along the length direction. The upper supports 11 and the lower supports 12 are each provided with a mounting member 4 for supporting the conveying rollers 13 to rotate. A connecting member 3 is arranged between the upper support 11 and the lower support 12, and the connecting member 3 is provided in at least two groups and arranged on both sides of the rack 1 along the width direction in the transverse direction respectively.

[0033] Referring to Figure 1 and Figure 2 The connecting member 3 includes a hinge block one 31, a hinge block two 32 and an intermediate plate. Between adjacent upper supports 11 and lower supports 12, the hinge block one 31 is rotatably connected with the upper support 11 in the transverse direction, the hinge block two 32 is rotatably connected with the lower support 12 in the transverse direction, and the hinge block one 31 and the hinge block two 32 are each fixed with a plurality of through rods 33 on the side close to each other. When the hinge block one 31 or the hinge block two 32 moves, the corresponding through rod 33 moves. The intermediate plate is located between the hinge block one 31 and the hinge block two 32, and all the through rods 33 pass through the intermediate plate along the axis direction of the through rod 33 and are slidably connected with the intermediate plate. The two ends of the through rod 33 are threadedly connected with a positioning nut 34, and when the positioning nut 34 is rotated, the positioning nut 34 moves along the axis direction of the through rod 33. The two positioning nuts 34 on the same through rod 33 are located on both sides of the intermediate plate and abut against the intermediate plate, thereby limiting the relative movement of the through rod 33 and the intermediate plate.

[0034] Referring to Figure 1 and Figure 2 By adjusting the position of the positioning nut 34, the through rod 33 is correspondingly moved relative to the intermediate plate along the axis direction, the hinge block one 31 and the hinge block two 32 are moved close to or away from each other, and the adjacent upper support 11 and lower support 12 are moved. When it is required to deflect the adjacent upper support 11 and lower support 12 in the transverse direction, only the connecting member 3 on the side of the adjacent upper support 11 and lower support 12 is adjusted, or the connecting members 3 on both sides are adjusted in the opposite direction, which can meet the adjustment requirement. The adjacent upper supports 11 and lower supports 12 are sequentially adjusted, and the bending of the whole rack 1 is realized.

[0035] Referring to Figure 1 and Figure 3The installation piece 4 for supporting the rotation of the conveying roller 13 is arranged between the upper support 11 and the lower support 12, and the installation piece 4 comprises a transfer rod 41, two side transfer rods one 42 and two side transfer rods two 43. The transfer rod 41 is horizontally arranged and fixedly connected with the corresponding upper support 11 or lower support 12 in the vertical direction. The upper support 11 and the lower support 12 support and position the corresponding transfer rod 41. The two side transfer rods one 42 are respectively arranged on both sides of the transfer rod 41 along the axial direction. The side transfer rod two 43 corresponds to the side transfer rod one 42 and is arranged on the side of the side transfer rod one 42 away from the transfer rod 41.

[0036] With reference to Figure 3 and Figure 4 The two ends of the side transfer rod one 42 are fixedly connected with a connecting block 421. The connecting block 421 is provided with an installation groove 422 in the vertical direction. The transfer rod 41 and the side transfer rod two 43 are fixedly connected with a rotating block 431 on the side close to the transfer rod 41. The rotating block 431 is located in the installation groove 422 and in contact with the inner wall of the installation groove 422. The connecting block 421 is provided with a rotating rod 423 penetrating through the installation groove 422 in the horizontal direction. The rotating rod 423 is rotationally connected with the connecting block 421 and penetrates through the rotating block 431 and is rotationally connected with the rotating block 431. The connecting block 421 limits the rotating block 431 through the rotating rod 423, so that the rotating block 431 rotates around the rotating rod 423, thereby realizing the overturning of the side transfer rod one 42 and the side transfer rod two 43 in the vertical direction. The connecting block 421 is fixedly connected with a circular ring block 424 coaxial with the rotating rod 423. The outer circle of the circular ring block 424 is uniformly provided with a plurality of positioning grooves 425 in the circumferential direction. The deflection angle between adjacent positioning grooves 425 is set according to a predetermined value, such as 1 degree, 2 degrees, 3 degrees, etc.

[0037] With reference to Figure 3 and Figure 4 The rotating block 431 is provided with a positioning piece comprising a positioning block 441 and a fixed screw 442. The rotating block 431 is provided with an opening on the side close to the circular ring block 424. The positioning block 441 is located in the opening and in contact with the inner wall of the opening. The fixed screw 442 penetrates through the positioning block 441 and is threadedly connected with the rotating block 431, so that the positioning block 441 is detachable. The rotating block 431 limits the deflection of the positioning block 441 around the fixed screw 442 through the inner wall of the opening, thereby realizing the positioning of the positioning block 441. One side of the positioning block 441 is opposite to the outer circle of the semicircular block, and the positioning block 441 is fixedly connected with a plurality of clamping blocks 443 matched with the positioning grooves 425. When the clamping block 443 is inserted into any positioning groove 425, the clamping block 443 is in contact with the inner wall of the positioning groove 425, thereby limiting the rotation of the semicircular block and locking the rotation between the rotating block 431 and the connecting block 421.

[0038] With reference to Figure 1 and Figure 3The upper support 11 and the lower support 12 are provided with a support 5 for supporting the side turning stick two 43, the support 5 comprises a moving block 51 and a support plate 52, the moving block 51 is in sliding connection with the corresponding upper support 11 or lower support 12 in the vertical direction, and the upper support 11 and the lower support 12 are provided with an adjusting screw 53, the adjusting screw 53 penetrates through the moving block 51 and is in threaded connection with the moving block 51. When the adjusting screw 53 is rotated, the adjusting screw 53 drives the corresponding moving block 51 to move in the vertical direction. One end of the support plate 52 is hinged to the moving block 51 in the vertical direction, and the other end is hinged to the corresponding side turning stick two 43 in the vertical direction. When the moving block 51 moves, it drives the corresponding side turning stick two 43 and the side turning stick one 42 to move in the vertical direction, thereby facilitating the adjustment of the deflection angle of the side turning stick two 43 and the side turning stick one 42 in the vertical direction.

[0039] With reference to Figure 1 and Figure 4 , the positioning block 441 is disassembled during adjustment, and the adjustment angle is set according to the integer multiple of the deflection angle of the positioning groove 425 of the circular ring block 424, the positioning block 441 is installed back to the original position after adjustment, thereby realizing the overall locking and positioning of the mounting part 4, and the support plate 52 is beneficial to improve the structural stability of the side mounting part 4. In the bending and turning position close to the rack 1, the mounting part 4 is adjusted in sequence by the support 5, so that the side turning stick one 42 and the side turning stick two 43 located on the upper support 11 are both deflected upward, and the side turning stick one 42 and the side turning stick two 43 located on the lower support 12 are both deflected downward, and the deflection angle gradually increases as the turning position is approached.

[0040] With reference to Figure 1 and Figure 3 , a plurality of conveying rollers 13 are respectively rotatably connected to the outside of the middle turning stick 41, the side turning stick one 42 and the side turning stick two 43, and move synchronously with the corresponding middle turning stick 41, side turning stick one 42 and side turning stick two 43, so that the plurality of conveying rollers 13 at the same upper support 11 or lower support 12 are arranged along the length trajectory of the mounting rack. The belt 2 is sleeved outside all the conveying rollers 13 and is in rolling connection with the conveying rollers 13. The ends of the rack 1 in the length direction are provided with driving rollers for supporting and driving the belt 2 to rotate, and the rack 1 is provided with a driving motor for driving the driving rollers to rotate, and the driving rollers and the driving motor are prior art and are not specifically embodied in the drawings.

[0041] The working principle of the embodiment 1 is that the conveying roller 13 supports and positions the belt 2, and the belt 2 is deformed synchronously with the arrangement direction of the conveying roller 13 near the bending position of the rack 1, so that the side edges of the belt 2 gradually bend to the middle position and the bending angle gradually increases. For the belt 2 supported by the upper support 11, when conveying the ore, the ore is placed on the upper end surface of the belt 2, and the turned side edges of the belt 2 are beneficial to reduce the probability of ore falling. The turning angle of the side edges of the belt 2 is adjustably arranged, and when the belt 2 is turned in the transverse direction after the rack 1 is bent, the deformation of the side edges of the belt 2 is mainly in the thickness direction, and the deformation range in the thickness direction of the belt 2 is much larger than the deformation range in the width direction, thereby beneficial to expand the overall transverse bending deformation amount of the belt 2, reduce the required turning radius of the belt 2, realize large-angle turning of the conveying line, shorten the overall length of the conveying line, and improve the conveying efficiency of the ore.

[0042] Embodiment 2 With reference to Figure 5 and Figure 6 The difference between the embodiment and the embodiment 1 is that the upper support 11 is provided with a limiting piece for tensioning the supporting plate 52, the limiting piece comprises a winding disc 61 and a pull rope 62, the winding disc 61 is rotationally connected with the upper support 11 in the vertical direction, and the winding disc 61 is coaxially fixed with a worm wheel 65.

When the adjusting screw 53 is rotated, the adjusting screw 53 drives the worm wheel 65 to rotate through the worm 66.

[0043] With reference to Figure 5 and Figure 6 The supporting plate 52 is rotationally connected with a connecting disc 63 in the vertical direction, the connecting block 421 is located on the side of the supporting plate 52 away from the second side turning roll 43, the connecting disc 63 is slidingly connected with a hanging block 64 in the diameter direction, and the connecting disc 63 is provided with a tightening screw 611 in the moving direction of the hanging block 64.

[0044] With reference to Figure 5 and Figure 6One end of the pull rope 62 is fixedly connected with the winding disc 61, and the other end is connected with the hanging block 64 by winding around the winding disc 61. The pull rope 62 is in a tightened state, thereby tensioning the support plate 52, which is conducive to improving the carrying capacity of the support plate 52 and improving the working stability of the support plate 52.
