Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, and in particular to a rotary lifting belt conveyor. Background Art

[0002] In a traditional rotary lifting belt conveyor, the belt conveyor body has the functions of deflection and rotation, so it can achieve belt transmission effects at different positions and heights. However, since the deflection method is used to control the material lifting height, the walking machine body needs to be moved again and repositioned and supported when the transmission height is changed. The operation is complicated. In many occasions, such as material transmission at different heights on the same vertical plane, material transmission at different horizontal positions at the same height, etc., it is necessary to repeatedly shift the walking machine body to achieve the material transmission function at different positions, which is very troublesome. In addition, existing equipment usually uses an integrally supported support frame to support the belt conveyor, which is not adaptable and has a small scope of application. The existing equipment cannot change the direction of the discharge when discharging at the top, which often causes the material to collide with the contact surface when discharged from the equipment, causing certain damage.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention designs a segmented, retractable, self-adaptive tensioning and cleaning rotating and lifting belt conveyor capable of realizing split support. Compared with the traditional revolving and lifting belt conveyor, the segmented feeding mechanism adopts a segmented design including a telescopic conveyor frame and a segmented conveyor frame. By adjusting the deflection direction of the segmented conveyor frame, the discharging angle can be controlled. In most cases, the material can be discharged horizontally, reducing the probability of material damage and improving the transmission effect. Through the telescopic design of the telescopic conveyor frame, it is ensured that after the walking machine body determines the transmission position and performs positioning and locking, it does not need to change its position due to changes in the transmission height and the like. In smaller usage scenarios, it is more appropriate to use the device for material transmission. When the base angle of the telescopic conveyor frame and the walking machine body changes, the tensioning effect of the adaptive tensioning mechanism on the belt can be adaptively changed according to the different deflection angles, thereby ensuring that the belt can be in a tensioned state at different deflection angles, ensuring the transmission effect, and being able to clean the belt at the corresponding position during the tensioning process, thereby improving the transmission effect of the continuous use of the belt.

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-10The rotary lifting belt conveyor shown in the figure includes a walking body, on which a rotary driving mechanism, a deflection and lifting mechanism and a belt conveyor frame are provided, and also includes a telescopic driving mechanism 2, an adaptive tensioning mechanism 3, a cleaning mechanism 4 and a connecting support mechanism 5. The belt conveyor frame is a segmented feeding mechanism 1, and the segmented feeding mechanism 1 is divided into a telescopic conveying frame 11 and a segmented conveying frame 12. The telescopic conveying frame 11 and the segmented conveying frame 12 are connected by a connecting support mechanism 5. The telescopic conveying frame 11 is transmission-connected to the rotary driving mechanism and the deflection and lifting mechanism. The end of the telescopic conveying frame 11 away from the walking body is connected to the segmented conveying frame 12. The adaptive tensioning mechanism 3 is installed on the segmented conveying frame 12. The cleaning mechanism 4 is arranged in the adaptive tensioning mechanism 3. The cleaning mechanism 4 and the adaptive tensioning mechanism 3 cooperate to tension and clean the belt at the connection between the telescopic conveying frame 11 and the segmented conveying frame 12. The deflection and lifting mechanism are transmission-connected to the adaptive tensioning mechanism 3.

[0021] In a conventional rotary lifting belt conveyor, the belt conveyor body has the functions of deflection and rotation, so that the belt transmission effect at different positions and different heights can be achieved. However, since the deflection method is used to control the material lifting height, the walking machine body needs to be re-transferred and re-positioned and supported when the transmission height is changed, which is complicated to operate. In many occasions, such as material transmission at different heights on the same vertical plane, material transmission at different horizontal positions at the same height, etc., the walking machine body needs to be repeatedly displaced to achieve the material transmission function at different positions, which is very troublesome. In addition, the existing equipment usually uses a fixed support frame to support the belt conveyor, which is not adaptive. The existing equipment cannot change the direction of the material discharge when discharging from the top, which often causes the material to collide with the contact surface when discharged from the equipment, causing certain damage. The present invention designs a segmented, retractable, adaptive tensioning and cleaning function, and split-type support rotary lifting belt conveyor. Compared with the traditional rotary lifting belt conveyor, the segmented feeding mechanism 1 adopts a segmented design including a telescopic conveying frame 11 and a segmented conveying frame 12. By adjusting the deflection direction of the segmented conveying frame 12, the discharge angle can be controlled. In most cases, the material can be discharged horizontally, reducing the probability of material damage and improving the transmission effect. The telescopic design of the telescopic conveying frame 11 ensures that after the walking body determines the transmission position and performs positioning and locking, it does not need to change its position due to changes in the transmission height, etc. In smaller usage scenarios, it is more appropriate to use this equipment for material transmission. When the base angle of the telescopic conveying frame 11 and the walking body changes, the adaptive tensioning mechanism 3 can be adaptively changed according to the different deflection angles to adjust the tensioning effect of the belt, thereby ensuring that the belt is in a tensioned state at different deflection angles, ensuring the transmission effect, and being able to clean the belt at the corresponding position during the tensioning process, thereby improving the transmission effect of the continuous use of the belt.

[0022] The telescopic conveying frame 11 includes a head telescopic frame 111, a segmented telescopic frame 112 and an external mounting frame 113. There are several segmented telescopic frames 112. The head telescopic frame 111 is located at the innermost part, and the external mounting frame 113 is located at the outermost part. Several segmented telescopic frames 112 are sequentially arranged between the head telescopic frame 111 and the external mounting frame 113. Limiting plates are fixedly provided at both ends of the outer side walls of the head telescopic frame 111, the external mounting frame 113 and each segmented telescopic frame 112. The head telescopic frame 111, the segmented telescopic frame 112 and the external mounting frame 113 slide with each other. The top ends of the head telescopic frame 111, the segmented telescopic frame 112 and the external mounting frame 113 are all provided with a first support plate for supporting the belt, and the top end of the segmented conveying frame 12 is provided with a second support plate. The length direction of the head telescopic frame 111, the segmented telescopic frame 112 and the external mounting frame 113 is consistent with the overall telescopic direction of the telescopic conveying frame 11.

[0023] The segmented telescopic frame 112 and the head telescopic frame 111 can be telescopically arranged on the external mounting frame 113, and the overall synchronous telescopic function is driven by the telescopic driving mechanism 2 to adapt to different usage scenarios. The overall equipment does not require a larger supporting frame. Compared with traditional equipment, the equipment shown in the present invention is more convenient to operate, and because it is a telescopic structure, there is a certain supporting force between each other, and the overall strength is not low. Combined with the split design of the connecting support mechanism 5, it still has good supporting capacity, can meet the transmission needs of heavier materials, and has a wide range of applications.

[0024] The telescopic drive mechanism 2 includes a telescopic drive assembly 21, a limit assembly 22 and a belt winding mechanism 23, all of which are arranged on the telescopic conveying frame 11. The telescopic drive assembly 21 includes a first rotary driver 211, a driving shaft 212, a linkage gear 213, a linkage shaft 214, an annular rack 215, a limit support frame 216 and a telescopic transmission rack 217. The first rotary driver 211 is fixedly mounted on the outer wall of the external mounting frame 113. The length direction of the driving shaft 212 is perpendicular to the telescopic direction of the telescopic conveying frame 11. The output end of the first rotary driver 211 is fixedly connected to the end of the driving shaft 212. Each segmented telescopic frame 112 and the head telescopic frame 112 are connected to each other. The outer wall of the 11 is provided with a linkage gear 213, a linkage shaft 214, an annular rack 215, a limit support frame 216 and a telescopic transmission rack 217. The segmented telescopic frame 112 and the head telescopic frame 111 are provided with a linkage gear 213 and a linkage shaft 214 at one end close to the external mounting frame 113. The linkage gear 213 is fixedly connected to the linkage shaft 214, and the annular rack 215 is sleeved on the linkage shaft 214. The linkage gear 213 is meshed with the annular rack 215. A telescopic transmission rack 217 is fixedly provided on the outer wall, and the telescopic transmission rack 217 is meshed with the linkage gear 213. A limit support frame 216 is fixedly installed on the outer wall of the head telescopic frame 111 and the segmented telescopic frame 112, and the limit support frame 216 is located in the annular rack 215. The belt winding mechanism 23 includes a second lifting mounting frame 231, a synchronous wheel 232, a first threaded rod 233, a first winding roller 234, a second winding roller 235 and a transmission gear set. The gear transmission set is connected to the driving shaft 212 through the synchronous wheel 232. Transmission connection, the transmission gear set is transmission connected with the first threaded rod 233, the first threaded rod 233 is threadedly connected with the second lifting mounting frame 231, the second lifting mounting frame 231 is vertically slidably arranged inside the external mounting frame 113, the first winding roller 234 is axially connected to the end of the top of the external mounting frame 113 away from the head telescopic frame 111, the second winding roller 235 is axially connected to the second lifting mounting frame 231, and the first winding roller 234 and the second winding roller 235 are provided with a plurality of them and are staggered along the length direction of the external mounting frame 113.

[0025] When the telescopic conveying frame 11 needs to be telescopic, the output of the first rotary driver 211 drives the driving shaft 212 to rotate. When the driving shaft 212 rotates, it drives the annular rack 215 to rotate. The annular rack 215 drives the linkage gear 213 and the linkage shaft 214 installed on the next-level segmented telescopic frame 112 to rotate. When the linkage gear 213 rotates, under the meshing and limiting action of the annular rack 215 and the telescopic transmission rack 217, the head telescopic frame 111 or the segmented telescopic frame 112 is driven to extend forward, thereby realizing the synchronous telescopic function. The limiting support frame 216 supports and limits the annular rack 215. The limit support frame 216 is used to ensure that the linkage gear 213 can fit with the annular rack 215 no matter where it moves. The telescopic transmission rack 217 is fixed. The rotation of the linkage gear 213 will drive the head telescopic frame 111 or the segmented telescopic frame 112 of the next level to be telescopic, and the rotation of the linkage shaft 214 will drive the annular rack 215 connected thereto to operate. During the operation, the annular rack 215 will drive the linkage gear 213 to rotate, thereby realizing the overall telescopic driving function.

[0026] When the telescopic conveyor frame 11 is extended or retracted, the belt laid on the telescopic conveyor frame 11 follows the extension and retraction. The belt winding mechanism 23 is used to realize the winding and unwinding process of the belt. When the first rotary driver 211 drives the driving shaft 212 to rotate, the driving shaft 212 drives the gear transmission device connected thereto to move through the synchronous wheel 232. The gear transmission device drives the first threaded rod 233 to rotate, and then can drive the second lifting installation frame 231 to perform a lifting operation, thereby changing the position of the second winding roller 235 installed on the second lifting installation frame 231. The belt is staggered between the first winding roller 234 and the second winding roller 235. When the first winding roller 234 and the second winding roller 235 are close to each other, the length of the stored belt is reduced, corresponding to the stage of the telescopic conveyor frame 11 expanding outward. When the first winding roller 234 and the second winding roller 235 are away from each other, the length of the stored belt is increased, corresponding to the stage of the telescopic conveyor frame 11 contracting inward.

[0027] The limiting assembly 22 includes a bidirectional push cylinder 221, a fixed limiting rod 222, a limiting collar 223, a first telescopic rod 224, a locking ring 225 and a fixing ring 226. The bidirectional push cylinder 221 is fixedly mounted on the outer wall of the external mounting frame 113. The fixed limiting rod 222 is arranged on the external mounting frame 113. The limiting collar 223 is provided with two and respectively sleeved on both ends of the fixed limiting rod 222. The two output ends of the bidirectional push cylinder 221 are respectively fixedly connected to the two fixed limiting rods 222. The first telescopic rod 224, a locking ring 225 and a fixing ring 226. The rod 224, the locking ring 225 and the fixing ring 226 are each provided with two groups and are respectively located at the two ends of the telescopic conveying frame 11. One end of the first telescopic rod 224 is transmission-connected to the linkage shaft 214 in the head telescopic frame 111 or the segmented telescopic frame 112, and the other end of the first telescopic rod 224 is fixedly connected to the limiting collar 223. The end of the first telescopic rod 224 is fixedly connected to the locking ring 225. Each linkage shaft 214 is fixedly connected to the fixing ring 226, and the locking ring 225 and the fixing ring 226 are slidably engaged.

[0028] When the limit assembly 22 is working, the output of the two-way pushing electric cylinder 221 drives the limit ring 223 to slide on the fixed limit rod 222, and the first telescopic rod 224 connected to the limit ring 223 drives the locking ring 225 to slide synchronously, and the locking ring 225 is displaced on the linkage shaft 214, so that the locking ring 225 and the fixed ring 226 installed on the linkage shaft 214 fit and lock, that is, the locking function of the linkage shaft 214 is realized, that is, the overall telescopic process is locked to prevent deviation during transmission, thereby improving the stability of the equipment.

[0029] The adaptive tensioning mechanism 3 includes a tensioning assembly 31, a lifting drive assembly 32, a transmission connection device 33 and a universal connection assembly 34.

[0030] When the adaptive tensioning mechanism 3 is working, the belt is sunken into the segmented conveyor frame 12 through the limit roller 311 and the lifting roller 312, and the belts on both sides of the top of the sunken part are close to each other, so as to minimize the gap in the center of the sunken part and improve the passability of the material above the sunken part. When the belt is tensioned, it passes through the limit roller 311, two lifting rollers 312 and another limit roller 311 in sequence, so that the material can be transported normally. When the belt tension needs to be controlled, it only needs to adjust the height of the first lifting mounting frame 313 to adjust the length of the belt in the sunken part between the lifting roller 312 and the limit roller 311, thereby realizing the control function of the belt tension. The limit roller 311 is a passive roller, and the lifting roller 312 can be an active roller to improve the belt transmission effect.

[0032] When the deflection and lifting mechanism is working, it will drive the external mounting frame 113 to deflect on the base of the walking body. At this time, the hinge rod installed on the base of the walking body and the external mounting frame 113 deflect, that is, relative to the external mounting frame 113, the arc rack 334 installed on the arc frame 333 rotates, and the arc rack 334 drives the first transmission gear 331 installed on the external mounting frame 113 to rotate, and the first transmission gear 331 drives the first rotating shaft 332 fixedly connected thereto to rotate, and then drives the first telescopic transmission rotating rod 335 to rotate through the driving gear set, and drives the universal connection assembly 34 to move through the first telescopic transmission rotating rod 335.

[0033] The universal connection assembly 34 includes a second telescopic transmission rod 341, a universal connection joint 342 and a limit mounting plate 343. The lifting drive assembly 32 includes a second threaded rod 321, a second rotating shaft 322, a driven gear set 323 and a bevel gear 324. The universal connection joint 342 is installed at an end of the second telescopic transmission rod 341 away from the segmented conveying rack 12. The second telescopic transmission rod 341 is connected to the segmented conveying rack 12 through the limit mounting plate 343. The first telescopic transmission rod 335 is connected to the second telescopic transmission rod 341 through the universal connection joint 342. Transmission connection, the second threaded rod 321 is installed in the vertical lifting groove 121, the second threaded rod 321 is threadedly connected to the first lifting mounting frame 313, the length direction of the second rotating shaft 322 is consistent with the length direction of the segmented conveying frame 12, the second rotating shaft 322 is rotatably installed on the segmented conveying frame 12, the second rotating shaft 322 is transmission connected to the second telescopic transmission rotating rod 341 through the driven gear set 323, the second rotating shaft 322 is transmission connected to the second threaded rod 321 through the bevel gear 324, and the top end of the second threaded rod 321 is rotationally connected to the external mounting frame 113.

[0034] When the first telescopic transmission rotating rod 335 rotates, the second telescopic transmission rotating rod 341 is driven to rotate through the universal connection joint 342. The universal connection joint 342 is used to ensure that the transmission connection relationship between the head telescopic frame 111 and the segmented conveying frame 12 can be ensured regardless of the deflection angle. The limit mounting plate 343 is used to install the second telescopic transmission rotating rod 341 on the segmented conveying frame 12.

[0035] The cleaning mechanism 4 includes a second rotary driver 41, a cleaning roller 42 and a bidirectional spiral scraper 43. The second rotary driver 41 is fixedly mounted on one of the first lifting mounting frames 313. The cleaning roller 42 is horizontally arranged. The two ends of the cleaning roller 42 are respectively axially connected to the two first lifting mounting frames 313. The cleaning roller 42 is located between the two lifting rollers 312. The output end of the second rotary driver 41 is fixedly connected to one end of the cleaning roller 42. The bidirectional spiral scraper 43 is fixedly arranged on the outer wall of the cleaning roller 42. The end of the cleaning roller 42 is transmission-connected to the lifting roller 312 through an auxiliary belt transmission assembly.

[0036] When the cleaning mechanism 4 is working, the output of the second rotary driver 41 drives the cleaning roller 42 fixedly connected thereto to rotate. When the cleaning roller 42 rotates, it drives the bidirectional spiral scraper 43 fixedly installed on its outer wall to rotate, so that the surface of the belt is scraped by the bidirectional spiral scraper 43. When rotating, the bidirectional spiral scraper 43 can push the stains to both ends, thereby realizing the stain discharge operation.

[0037] It is worth mentioning that both ends of the bidirectional spiral scraper 43 are covered with dust covers, which are connected to the outside of the segmented conveying frame 12 through a telescopic tube, thereby realizing the outward discharge of stains and preventing stains from accumulating inside the equipment. A dust collecting chamber can be connected to the other end of the telescopic tube to facilitate dust collection.

[0038] The connecting support mechanism 5 includes a top connecting platform 51 and a bottom supporting platform. A lifting assembly and a supporting plate for supporting the top connecting platform 51 are arranged in the bottom supporting platform. The top connecting platform 51 is located directly below the connection between the head telescopic frame 111 and the segmented conveying frame 12. A first connecting rod 52, a limiting support plate 53, a second connecting rod 54, a lifting electric cylinder 55 and an elastic hinge seat 56 are arranged on the top connecting platform 51. One end of the first connecting rod 52 is hinged to the end of the head telescopic frame 111 close to one end of the segmented conveying frame 12, and the other end of the first connecting rod 52 is hinged to one end of the top connecting platform 51 close to the head telescopic frame 111. A limiting support plate for limiting the angle of the first connecting rod 52 is provided. 53 is installed on the outer side wall of the head telescopic frame 111, the first connecting rod 52 is in conflict with the limiting support plate 53, one end of the second connecting rod 54 is hinged to the end of the head telescopic frame 111 close to the segmented conveying frame 12, the other end of the second connecting rod 54 is hinged to the end of the top connecting platform 51 away from the head telescopic frame 111, the lifting electric cylinder 55 is hingedly set on the top connecting platform 51, the output end of the lifting electric cylinder 55 is hinged to the end of the segmented conveying frame 12 away from the head telescopic frame 111, the head telescopic frame 111 and the segmented conveying frame 12 are connected by an elastic hinge seat 56, and a sliding groove arranged along the length direction of the first connecting rod 52 is provided at the hinge between the first connecting rod 52 and the head telescopic frame 111.

[0039] After the telescopic conveyor frame 11 and the segmented conveyor frame 12 are lifted, the top connecting platform 51 is located below the connection between the telescopic conveyor frame 11 and the segmented conveyor frame 12, and is used to support and limit the connection between the telescopic conveyor frame 11 and the segmented conveyor frame 12. The top connecting platform 51 and the bottom supporting platform are split-type designs. When heavy objects do not need to be transported, the support of the bottom supporting platform is not required. The rotation and lifting actions of the equipment are more convenient and efficient, and the transmission function can be quickly realized. When the object to be transported is heavy or the equipment needs to be more stable, the bottom supporting platform is operated. To the bottom of the top connecting platform 51, the support plate is lifted up by the lifting assembly, and the top connecting platform 51 is connected and supported by the support plate, which improves the overall stability of the equipment and can adapt to the transportation function of heavier materials. The setting of the sliding groove can enable the top connecting platform 51 to have a certain angle deflection function. When connected to the bottom supporting platform, the connection between the first connecting rod 52 and the head telescopic frame 111 is the lowermost end of the sliding groove. When not connected to the bottom supporting platform, the connection between the first connecting rod 52 and the head telescopic frame 111 is the uppermost end of the sliding groove.

[0040] The auxiliary belt transmission assembly includes a first driving gear 44 and a first driven gear 45. The first driving gear 44 is fixedly mounted on the end of the cleaning roller 42, and the first driven gear 45 is fixedly mounted on the end of the lifting roller 312. The first driving gear 44 is meshed with the first driven gear 45.

[0041] When the second rotary driver 41 drives the cleaning roller 42 to rotate, the auxiliary belt transmission component can be used to assist in pushing the belt inside the adaptive tensioning mechanism 3 to prevent the belt from getting stuck inside the adaptive tensioning mechanism 3, thereby improving the smoothness of the belt operation. The cleaning roller 42 is driven to rotate by the second rotary driver 41, and the cleaning roller 42 drives the first driving gear 44 fixedly connected thereto to rotate. When the first driving gear 44 rotates, it drives the first driven gear 45 meshing therewith to rotate. When the first driven gear 45 rotates, it drives the lifting roller 312 to rotate. The lifting roller 312 rotates to drive the belt forward, thereby realizing the auxiliary belt transmission function. It is worth mentioning that the rotation direction of the cleaning roller 42 is opposite to the rotation direction of the lifting roller 312, that is, the rotation direction of the bidirectional spiral scraper 43 on the cleaning roller 42 is opposite to the travel direction of the belt. This setting can increase the scraping speed and improve the cleaning effect on the belt surface. At the same time, the auxiliary pushing of the belt can also offset the influence of the cleaning and scraping operation on the belt transmission.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
