Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, and in particular to a belt conveyor for coal receiving while following a machine. Background Art

[0002] A roadheader is a highly efficient coal mining device integrating the functions of tunneling and support. The coal mined by the roadheader usually needs to be transported by a belt conveyor. The belt conveyor is also called a belt conveyor and is usually divided into two types: an inclined belt conveyor and a horizontal belt conveyor. In order to transport coal and other materials from a lower place to a higher place, the inclined belt conveyor generally fixes a plurality of retaining bars for carrying coal and other materials evenly on the conveying belt, and fixes retaining edges on both sides of the retaining bars to prevent coal and other materials from scattering. The horizontal belt conveyor only needs to horizontally transport coal and other materials, so a flat belt is generally used to horizontally transport the materials.

[0003] In the prior art, the belt, retaining bars and baffles on the inclined belt conveyor are usually integrally produced and formed, and generally the retaining bars and baffles cannot be disassembled, cleaned and replaced separately. Usually, the belt, retaining bars and baffles need to be disassembled, cleaned and replaced as a whole; the application scenarios of the inclined belt conveyor and the horizontal belt conveyor are relatively fixed and single, and it is difficult to replace each other in terms of functions. Therefore, in the operation process of receiving coal while following a roadheader and performing multi-scenario transportation, there is a need for both the inclined belt conveyor and the horizontal belt conveyor.

[0004] However, the existing belt conveyors for transporting coal and other materials have the following problems when in use: 1. Since the belt, retaining bars and baffles on the inclined belt conveyor need to be disassembled, cleaned and replaced as a whole, the overall operation burden of cleaning and maintenance is relatively heavy. And when some retaining bars are worn and damaged, affecting the use of the inclined belt conveyor, the whole belt and all retaining bars need to be replaced, and the damaged partial retaining bars cannot be replaced separately. The above operation method not only makes the overall disassembly and replacement steps cumbersome and inefficient, but also causes waste of materials and an increase in the overall production cost; 2. Since the retaining bars on the inclined belt conveyor cannot be disassembled and replaced separately, when a small number of retaining bars are damaged and do not completely affect the use of the inclined belt conveyor, in order to control costs, the situation where the whole belt and all retaining bars are not replaced immediately usually occurs, resulting in the damaged partial retaining bars affecting the overall transportation efficiency and effect of coal and other materials to a certain extent, and further affecting the progress of the overall transportation operation; 3. Since the inclined belt conveyor and the horizontal belt conveyor are difficult to replace each other and both have a use requirement, when multi-scenario transportation of coal and other materials is required, the overall number of equipment at the operation site is large and the occupied space is large, resulting in an increase in the overall space use cost and equipment operation and maintenance cost during the production and processing process.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 , a belt conveyor for coal receiving during mining, including a conveyor frame 1, an adjusting mechanism 2 and a docking mechanism 3 are arranged on the conveyor frame 1, and a matching mechanism 4 is arranged on the docking mechanism 3.

[0034] Please refer to Figure 1 and Figure 2 , the conveyor frame 1 includes a conveyor assembly 11, a conveyor belt 12 installed on the conveyor assembly 11, and a mounting assembly 13 arranged on the outer surface of the conveyor belt 12.

[0035] See also Figure 2 The conveying assembly 11 includes two groups of adjustment frames that are symmetrically distributed on the left and right, and each group of adjustment frames consists of a front bracket 111 and a rear bracket 112 that are distributed front and back and hinged to each other. The rear ends of the symmetrical front brackets 111 are fixedly provided with a connecting shaft 113 that is rotatably connected to the rear bracket 112. Tensioning rollers 114 are symmetrically rotated front and back between the symmetrical adjustment frames. A motor 115 whose driving end is fixedly connected to the right end of the rear tensioning roller 114 is fixedly provided at the rear end of the right adjustment frame. A plurality of supporting rollers 116 located between the tensioning rollers 114 are uniformly rotated front and back between the symmetrical adjustment frames.

[0036] See also Figure 3 The mounting assembly 13 includes two groups of sockets 131 symmetrically fixedly arranged on the outer surface of the conveyor belt 12, each group is composed of sockets 131 symmetrically distributed left and right. Two groups of mounting seats 132 are symmetrically fixedly arranged on the outer surface of the conveyor belt 12, each group is composed of a plurality of mounting seats 132 evenly distributed front and back. Positioning grooves 133 that pass through the upper end are symmetrically opened at the left and right ends of the mounting seats 132. Alignment plates 134 are symmetrically fixedly arranged on the upper surface of the mounting seats 132, and a T-shaped slot 135 that passes through left and right is commonly opened between the front and back symmetrical alignment plates 134.

[0037] See also Figure 1 and Figure 2 The adjusting mechanism 2 includes a supporting assembly 21 and an adjusting assembly 23 arranged on the conveying assembly 11 , and a tensioning assembly 22 is arranged on the supporting assembly 21 .

[0038] See also Figure 1 and Figure 4 The support assembly 21 includes L-shaped legs 211 fixedly arranged front and rear on opposite sides of the left-right symmetrical rear bracket 112, and rotating shafts 212 fixedly arranged front and rear on opposite sides of the left-right symmetrical front bracket 111, and an L-shaped rotating plate 213 is rotatably arranged on the rotating shaft 212, and an adjusting sleeve 214 is fixedly arranged on the lower side of the horizontal section of the L-shaped rotating plate 213, and a plurality of positioning holes 215 penetrating front and rear are evenly arranged on the adjusting sleeve 214, and a telescopic rod 216 that moves up and down is slidably arranged in the adjusting sleeve 214, and a positioning hole 217 penetrating front and rear is opened on the upper end of the telescopic rod 216 and docked and positioned with the corresponding positioning hole 215 through a latch, and a bottom plate 218 is fixedly arranged on the lower ends of the left-right symmetrical telescopic rods 216.

[0039] When the current support 111 rotates upward by a specific angle around the connecting shaft 113, the rotating shaft 212 rotates synchronously by a certain angle around the connecting shaft 113 and drives the corresponding L-shaped rotating plate 213 and the adjusting sleeve 214 to move upward by a specific distance. Since the bottom plate 218 will always be in contact with the flat ground under the action of gravity, the L-shaped rotating plate 213 and the adjusting sleeve 214 will always remain vertical during the process of moving upward by a specific distance along the telescopic rod 216 until the second positioning hole 217 is aligned with the corresponding first positioning hole 215. At this time, the L-shaped rotating plate 213 and the adjusting sleeve 214 can be stably positioned at the current position through the first pin, so as to support the front support 111 that rotates upward by a specific angle.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.

[0041] When the conveyor belt 12 is synchronously adjusted with the upwardly rotating front support 111, in order to ensure that the conveyor belt 12 can stably convey materials such as coal, it is necessary to keep the conveyor belt 12 always tensioned and attached to the surface of the supporting roller 116. At this time, first adjust the docking mechanism 3, and then drive the U-shaped plate 224 and the tensioning wheel 225 to move downward synchronously through the hydraulic cylinder 223 and press them against the upper side of the conveyor belt 12 until the conveyor belt 12 is tensioned and stably attached to the surface of the supporting roller 116. At this time, the inclination angles of the front and rear parts on the upper side of the conveyor belt 12 will be basically the same as the inclination angle between the front support 111 and the rear support 112.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.

[0043] When the front support 111 needs to be driven to rotate upward by a certain angle around the coupling shaft 113, the hydraulic cylinder two 233 drives the corresponding U-shaped plate two 234 and the sliding shaft 235 to move forward by a certain distance. The sliding shaft 235 then presses the corresponding kidney-shaped groove 232 and slides relative to the kidney-shaped groove 232, thereby pushing the lower end of the corresponding transmission plate 231 forward. The transmission plate 231 then drives the upper end of the coupling shaft 113 to rotate relative to the front end of the rear support 112. The coupling shaft 113 then drives the rear ends of the front supports 111 on both sides to rotate synchronously, so that the front support 111 rotates upward by a certain angle around the coupling shaft 113.

[0044] Please refer to Figure 1 、 Figure 5 and Figure 9 As shown in, the docking mechanism 3 includes a positioning component 31 provided on the adjusting frame, a docking component 32 provided on the positioning component 31, and a clamping component 33 jointly provided on the positioning component 31 and the docking component 32.

[0045] Please refer to Figure 5 、 Figure 6 and Figure 7 As shown in, the positioning component 31 includes a group of second supports fixedly provided on the left and right symmetric front supports 111 and rear supports 112. Each group consists of upper and lower symmetric second supports. A sliding rod 311 that moves left and right is slidably provided on the second supports. A U-shaped baffle 312 is fixedly provided at one end of the upper and lower symmetric sliding rods 311 close to the conveyor belt 12. The opening directions of the front and rear symmetric U-shaped baffles 312 are opposite to each other. The left and right symmetric U-shaped baffles 312 are jointly inserted and positioned with a corresponding group of first sockets 131 through a first rod. A straight insertion plate 313 is fixedly provided at the rear end of the horizontal section on the upper side of the front U-shaped baffle 312. A plate groove 314 that is inserted and matched with the corresponding straight insertion plate 313 is provided at the front end of the horizontal section on the upper side of the rear U-shaped baffle 312. A first connecting plate 315 is fixedly provided at one end of the upper and lower symmetric sliding rods 311 far from the conveyor belt 12. A second socket 316 is fixedly provided on the side of the first connecting plate 315 far from the sliding rod 311. Positioning frames 317 are fixedly provided on the left and right symmetric front supports 111 and rear supports 112 and on the side of the corresponding second socket 316 close to the coupling shaft 113. Positioning holes three 318 that penetrate through the front and rear and are docked and positioned with the corresponding second socket 316 through a second pin are symmetrically provided on the positioning frames 317.

[0046] Please refer to Figure 3 、 Figure 7 、 Figure 8 and Figure 9, the docking component 32 includes docking seats 321 symmetrically arranged left and right on the corresponding mounting seats 132. On the opposite sides of the symmetrically arranged U-shaped baffles 312 left and right, two groups of docking seats 321 are symmetrically mounted up and down. Each group consists of a plurality of docking seats 321 evenly distributed front and back. At one end of the docking seat 321 close to the conveyor belt 12, a plug 322 is fixedly arranged and is in plug-in fit with the corresponding positioning groove 133. On the opposite sides of the symmetrically arranged docking seats 321 left and right, a retaining bar 323 is hinged. At the lower ends of the opposite sides of the symmetrically arranged retaining bars 323 left and right, a T-shaped plug board 324 is fixedly arranged and is in plug-in fit with the corresponding T-shaped slot 135. On the upper side of the right retaining bar 323, a docking column 325 facing the left is fixedly arranged through the third support. On the upper side of the left retaining bar 323, a second connecting plate 326 is fixedly arranged through the fourth support. On the right side of the second connecting plate 326, two docking claws 327 that are symmetrically arranged front and back and are in clamping fit with the corresponding docking column 325 are rotatably arranged through the fifth support. The symmetrically arranged docking claws 327 front and back are elastically connected to the corresponding second connecting plate 326 through springs.

[0047] When the conveyor belt 12 is to horizontally convey materials such as coal, first make the first connecting plate 315 drive the corresponding U-shaped baffle 312 to move towards the second support through the sliding rod 311. The U-shaped baffle 312 then drives the corresponding docking seat 321 and the retaining bar 323 to move synchronously through the clamping component 33 until the second socket 316 is aligned with the third positioning hole 318 at the end of the corresponding positioning frame 317 away from the U-shaped baffle 312, and the second socket 316 and the third positioning hole 318 are docked and positioned through the second pin. Then, through the matching mechanism 4, all the retaining bars 323 are synchronously deflected by ninety degrees towards the center direction of the conveyor belt 12, so that the retaining bars 323 will not obstruct the conveying path of the conveyor belt 12 for horizontally conveying materials such as coal. Finally, the rear tensioning roller 114 is driven to rotate by the motor 115 so that the conveyor belt 12 can horizontally and directionally convey materials such as coal. The above operation method can retract the retaining bars 323 when the conveyor belt 12 is horizontally conveying, thereby reducing the overall loss of the retaining bars 323 while not affecting the horizontal conveying of the conveyor belt 12, further prolonging the overall service life of the retaining bars 323, and reducing the overall production and processing cost.

[0048] Such as Figure 8As shown, when the docking post 325 is to be snapped together with the corresponding pair of docking claws 327, the docking post 325 on the right and the pair of docking claws 327 on the left are moved relative to each other. The docking post 325 then presses against the right end of the pair of docking claws 327 and pushes them apart to the front and back sides respectively. The pair of docking claws 327 then rotate away from each other around the fifth support until the docking post 325 is completely inserted between the docking claws 327. Under the action of the spring, the pair of docking claws 327 are then snapped and positioned with the docking post 325. When it is necessary to release the snap positioning between the docking post 325 and the pair of docking claws 327, the docking post 325 and the pair of docking claws 327 are moved away from each other. The docking post 325 then again pushes the pair of docking claws 327 apart to the front and back sides respectively until the docking post 325 completely disengages from the pair of docking claws 327, thereby releasing the snap positioning between the docking post 325 and the pair of docking claws 327.

[0049] When the conveyor belt 12 is to convey materials such as coal upward at an inclination, first insert and position the socket one 131 and the corresponding U-shaped baffle 312 through the rod one, so that the docking seat 321 and the bar 323 can be stably positioned and installed on the corresponding mounting seat 132. Then, make the connecting plate one 315 drive the corresponding U-shaped baffle 312 to move away from the support two by the maximum distance until the symmetrically arranged bars 323 on the left and right are positioned together through the clamping fit between the corresponding docking columns 325 and the docking claws 327. At this time, the T-shaped plug plates 324 on the symmetrically arranged bars 323 on the left and right just insert into the same T-shaped slot 135, and the plug blocks 322 on the corresponding docking seats 321 also just insert into the corresponding positioning slots 133, so as to position and install the symmetrically arranged bars 323 on the corresponding mounting seats 132. At this time, the clamping components 33 on the docking seat 321 and the corresponding U-shaped baffle 312 can just be unlocked. Then, move the U-shaped baffle 312 towards the corresponding support two until the socket two 316 is aligned with the positioning hole three 318 at one end of the corresponding positioning frame 317 close to the U-shaped baffle 312 and is docked and positioned through the pin two. At this time, the clamping components 33 on each docking seat 321 and the corresponding U-shaped baffle 312 are just completely unlocked and separated from each other, so that the bar 323 and the corresponding docking seat 321 can move synchronously with the conveyor belt 12. Then, unlock the rod one and the socket one 131, and drive the front support 111 to rotate upward by a specific angle around the connecting shaft 113 through the hydraulic cylinder two 233. At this time, the U-shaped baffle 312 on the front support 111 rotates upward synchronously, and drives the straight plug plate 313 to rotate synchronously and dock and insert into the corresponding plate slot 314. The U-shaped baffle 312 and the straight plug plate 313 can prevent materials such as coal from scattering to the left and right during the conveying process. At the same time, the front support 111 is supported by the telescopic rod 216 and the adjusting sleeve 214. Finally, the conveyor belt 12 is tensioned and stably attached to the surface of the supporting roller 116 through the tensioning wheel 225, so that the conveyor belt 12 can be driven by the motor 115 to drive the bar 323 to convey materials such as coal upward from bottom to top. The above operation method can quickly adjust and convert the belt conveyor between the horizontal conveying and inclined conveying modes, so as to reduce the overall number of equipment during the production operation process, and thus greatly reduce the overall space usage cost and equipment operation and maintenance cost during the production and processing process.

[0050] Please refer to Figure 9 and Figure 10, the clamping component 33 includes clamping grooves 331 and elastic grooves 332 symmetrically arranged up and down on the docking seat 321 near one side of the corresponding U-shaped baffle 312. The clamping groove 331 is horizontally distributed and penetrates towards the corresponding U-shaped baffle 312. The elastic groove 332 is vertically distributed and communicates with the corresponding clamping groove 331. An elastic clamping member 333 inserted into the corresponding clamping groove 331 is elastically slidably arranged in the elastic groove 332. One end of the elastically slidable elastic clamping member 333 inserted into the corresponding clamping groove 331 is a bevel surface. A clamping head 334 that slides left and right is arranged in the clamping groove 331. The side of the clamping head 334 away from the corresponding U-shaped baffle 312 is an arc surface. A connecting column 335 is fixedly arranged on the side of the clamping head 334 close to the corresponding U-shaped baffle 312. A receiving groove 336 is jointly opened at the connection of the clamping head 334 and the corresponding connecting column 335. A magnetic ring 337 that is magnetically repulsive to the corresponding clamping head 334 and is in butt joint with the corresponding receiving groove 336 is slidably arranged on the connecting column 335. The left and right sides of the magnetically ring 337 that slides left and right are both bevel surfaces. One end of the connecting column 335 away from the corresponding clamping head 334 is fixedly connected to the corresponding U-shaped baffle 312 through a T-shaped base.

[0051] When the docking seat 321 installed on the mounting seat 132 needs to be docked and positioned with the corresponding U-shaped baffle 312 again, first insert and position the socket one 131 and the corresponding U-shaped baffle 312 through the rod one, and then move the U-shaped baffle 312 a certain distance away from the support two until the clamping head 334 is inserted into the corresponding clamping groove 331. The clamping head 334 then cooperates with the bevel surface at the lower end of the corresponding elastic clamping member 333 through the arc surface, causing the elastic clamping member 333 to first retract into the corresponding elastic groove 332. As the clamping head 334 continues to be inserted and passes over the corresponding elastic clamping member 333, under the elastic action of the elastic groove 332, the elastic clamping member 333 then extends again and is limited on the side of the clamping head 334 close to the corresponding connecting column 335, thereby positioning the corresponding clamping head 334 in the corresponding clamping groove 331 through the elastic clamping member 333, and further docking and positioning the docking seat 321 installed on the mounting seat 132 with the corresponding U-shaped baffle 312. At this time, move the U-shaped baffle 312 towards the support two again until the socket two 316 is aligned with the positioning hole three 318 at the end of the corresponding positioning frame 317 away from the U-shaped baffle 312 and is docked and positioned through the pin two, which can cause the clamping head 334 to drive the corresponding docking seat 321 and the retaining strip 323 to move synchronously a certain distance through the clamping cooperation with the elastic clamping member 333, and release the locking of the corresponding docking column 325 and the paired docking claws 327, thereby detaching the docking seat 321 and the retaining strip 323 from the corresponding mounting seat 132.

[0052] When it is necessary to release the docking positioning between the docking seat 321 and the corresponding U-shaped baffle 312, first move the U-shaped baffle 312 in the direction away from the second support by the maximum distance. At this time, the symmetrically arranged left and right strip bars 323 are just docked and positioned on the corresponding mounting seat 132 through the corresponding docking posts 325 and docking claws 327. At the same time, the clamping head 334 is also completely inserted into the corresponding clamping groove 331. Driven by the T-shaped base, the magnetic ring 337 is also synchronously inserted into the corresponding clamping groove 331. And the magnetic ring 337 cooperates with the inclined surface on the corresponding elastic clamping member 333 through the inclined surface on the side close to the clamping head 334, so that the elastic clamping member 333 first retracts into the corresponding elastic groove 332. As the magnetic ring 337 continues to be inserted and passes over the corresponding elastic clamping member 333, under the elastic action of the elastic groove 332, the elastic clamping member 333 extends out again and is limited on the side of the magnetic ring 337 close to the corresponding T-shaped base. At this time, move the U-shaped baffle 312 to drive the T-shaped base in the direction close to the second support again. The clamping head 334 and the connecting column 335 move outwards from the clamping groove 331 synchronously. The corresponding magnetic ring 337 moves relative to the connecting column 335 under the restriction of the elastic clamping member 333 until the magnetic ring 337 moves into the corresponding receiving groove 336. The magnetic ring 337 moves synchronously with the clamping head 334 and cooperates with the inclined surface on the corresponding elastic clamping member 333 through the inclined surface on the side close to the T-shaped base, so that the elastic clamping member 333 retracts into the corresponding elastic groove 332 again until the clamping head 334 continuously moves outwards from the clamping groove 331 and passes over the corresponding elastic clamping member 333, thereby unlocking the clamping head 334 from the elastic clamping member 333 and pulling out the clamping head 334 from the clamping groove 331, and then releasing the docking positioning between the docking seat 321 and the corresponding U-shaped baffle 312, and stably installing the docking seat 321 and the strip bar 323 on the corresponding mounting seat 132. At this time, the magnetic ring 337 will move outwards along the connecting column 335 from the receiving groove 336 until it is reset under the repulsive force of the corresponding clamping head 334. The above operation method can not only install or adjust all the docking seats 321 and the strip bars 323 synchronously, ensuring the installation and adjustment efficiency of the overall strip bar 323, but also can realize the separate disassembly and cleaning of the docking seat 321 and the strip bar 323, thus greatly simplifying the overall cleaning and maintenance operations. And by separately disassembling and replacing the damaged strip bar 323, it is possible to avoid affecting the overall conveying efficiency and effect of the inclined belt conveyor due to the damage of a small number of strip bars 323, and at the same time, it also greatly reduces the waste of materials.

[0053] Please refer to Figure 5 and Figure 7 As shown in FIGS.

[0054] Please refer to Figure 7, the matching assembly 42 includes a plurality of electric sliders 421 that are evenly slidably arranged on the corresponding guide rails 41 before and after. A second connecting rod 422 is fixedly arranged between the adjacent electric sliders 421 on the same guide rail 41 before and after. On the side of the electric slider 421 away from the corresponding U-shaped baffle 312, a third connecting plate 423 is fixedly arranged. On the third connecting plate 423, spring rods 424 are symmetrically and elastically slidably arranged before and after. At one end of the symmetric spring rods 424 before and after close to the corresponding stop strip 323, a straight rack 425 that moves left and right is fixedly arranged together. On the side of the stop strip 323 away from the conveyor belt 12 and on the axis of the hinge point of the stop strip 323, a third connecting rod 426 is fixedly arranged. At one end of the third connecting rod 426 away from the corresponding stop strip 323, an arc rack 427 that meshes and drives with the corresponding straight rack 425 is fixedly arranged through a first plate member.

[0055] When all the stop strips 323 are to be deflected by ninety degrees synchronously towards the center direction of the conveyor belt 12, first, the docking seat 321 and the stop strip 323 are detached from the corresponding mounting seat 132 through the cooperation of the clamping assembly 33 on the U-shaped baffle 312 and the corresponding docking seat 321. The electric sliders 421 on the same guide rail 41 move synchronously away from the corresponding direct insertion plate 313 or plate groove 314. The third connecting plate 423 drives the corresponding straight rack 425 to move synchronously through the spring rod 424. The straight rack 425 drives the third connecting rod 426 to rotate synchronously through meshing and driving with the corresponding arc rack 427, so that the third connecting rod 426 drives the corresponding stop strip 323 to deflect by ninety degrees around the hinge point towards the center direction of the conveyor belt 12. The spring rod 424 can enable the straight rack 425 to move out of the way when moving the maximum distance away from the second support along with the corresponding U-shaped baffle 312, so as to prevent the straight rack 425 from colliding and jamming with the corresponding meshing arc rack 427 and hindering the movement of the U-shaped baffle 312; it should be noted that when putting materials such as coal on the conveyor belt 12, the materials should be avoided from the third connecting rod 426 and the arc rack 427 by installing a protective plate or a guide plate, etc., so as to prevent damage to the third connecting rod 426 and the arc rack 427.
