Long distance integral lifting ton bag conveyor

Abstract

The present invention relates to the field of ton bag conveyors, and in particular to long-distance integral lifting ton bag conveyors. During the use of the long-distance integral lifting ton bag conveyor, the change in ambient temperature will cause the conveyor belt to expand and contract. After long-term use, the conveyor belt will gradually wear or age. In addition, during the use of the ton bag conveyor, due to human operation and other reasons, the load distribution on the conveyor is prone to unevenness, which will cause the local tension of the conveyor belt to be too high. It includes a frame, and a propulsion mechanism is provided at one end of the inner side of the frame. The propulsion mechanism includes a first transmission shaft, the first transmission shaft is rotatably connected to the frame, and the end of the first transmission shaft away from the frame is fixedly connected to a first rotating wheel. When the tension of the conveyor belt is reduced or too large, the tension of the conveyor belt is adjusted by the propulsion mechanism. After the adjustment is completed, the propulsion mechanism is locked by the locking mechanism to prevent the adjusted conveyor belt from becoming more or less tensile again.

Description

Technical Field

[0001] The invention relates to the field of conveyors, in particular to a long-distance integral lifting ton bag conveyor. Background Art

[0002] Long-distance integral lifting bag conveyor is a kind of conveying equipment specially designed for long-distance and large-tonnage material handling. With the acceleration of industrialization and automation, the efficiency of logistics transportation and material handling has become a key factor for enterprises to improve productivity and reduce costs. Traditional manual handling and short-distance conveying equipment have been unable to meet the needs of large-scale, long-distance and high-efficiency material handling. Therefore, long-distance integral lifting bag conveyor came into being and became an indispensable logistics equipment in modern industrial production.

[0003] The long-distance integral lifting ton bag conveyor has the ability to continuously and stably transport materials over a long distance. It is suitable for large factories, warehouses, docks and other places that need to transport materials over long distances. Through the advanced lifting mechanism, the overall lifting of the conveyor is realized, which is convenient for docking with equipment or platforms at different heights, and improves the flexibility and efficiency of material handling. However, the long-distance integral lifting ton bag conveyor will cause the thermal expansion and contraction of the conveyor belt due to changes in ambient temperature during use. After long-term use, the conveyor belt will gradually wear or age. In addition, the load distribution on the conveyor is prone to unevenness due to human operation and other reasons during use, which will cause the local tension of the conveyor belt to be too high. Excessive tension will accelerate the wear of the conveyor belt and components such as the drive roller and the driven roller, thereby increasing the resistance of the conveyor during operation, resulting in increased energy consumption. Being in a high tension state for a long time will shorten the service life of the conveyor belt, which may cause the conveyor belt to break and cause safety accidents. If the tension of the conveyor belt is too low or there is a loose phenomenon, it will cause the conveyor belt to slip, resulting in material accumulation or scattering, affecting the conveying efficiency. In extreme cases, it will cause the conveyor belt to derail, resulting in the occurrence of serious safety accidents. Summary of the invention

[0040] like Figure 1 As shown, a plurality of lifting support frames 107 are fixedly connected to the outer walls on both sides of the frame 1, a hydraulic cylinder 108 is fixedly connected to the inner side of the lifting support frame 107, a lifting support rod 109 is fixedly connected to the output end of the hydraulic cylinder 108, and a foot 110 is fixedly connected to the other end of the lifting support rod 109. Example 2

[0041] Working principle: When using a long-distance integral lifting ton bag conveyor to transport goods, put the goods on the conveyor belt 2, start the motor 104, the output end of the motor 104 drives the input end of the reducer 105 to rotate, the output end of the reducer 105 drives the first roller 101 to rotate, the first roller 101 drives the conveyor belt 2 to move, and the conveyor belt 2 drives the remaining first roller 101, second roller 102, and third roller 103 to rotate synchronously to achieve continuous transportation of materials.

[0042] During long-term operation and carrying of materials, the conveyor belt 2 is stretched, worn and affected by external environmental factors, causing its original tension state to gradually weaken. The tension state of the conveyor belt 2 can be adjusted at any time according to the actual situation of use. When the tension state of the conveyor belt 2 needs to be adjusted, the motor 104 is turned off, and the second limit block 508 is pulled outward so that the second limit block 508 releases the restriction on the second pull rod 507. The second pull rod 507 is pulled outward. While the second pull rod 507 moves outward, it drives the third rack 505 to move outward and squeezes the second spring 506. The second spring 506 is compressed and pushes the second limit block 508 inward so that the second limit block 508 can be inserted into the groove at the end of the second pull rod 507. 406, and the third gear 403 is unlocked. At this time, the second rotating wheel 401 is rotated counterclockwise, and the second rotating wheel 401 drives the third transmission shaft 402 to rotate counterclockwise, and the third transmission shaft 402 drives the third gear 403 to rotate counterclockwise, and the third transmission shaft 402 drives the fourth gear 404 to rotate counterclockwise. The fourth gear 404 drives the second rack 405 to move linearly to the right through engagement, and the second rack 405 drives the rotating wheel 406 to rotate counterclockwise. The counterclockwise rotation of the rotating wheel 406 drives the two third connecting rods 407 to open to both sides, and the third connecting rod 407 drives the two clamping blocks 408 to open, thereby canceling the clamping effect on the second transmission shaft 305.

[0043] The first limit block 504 is then pulled outward to cancel the limit on the first pull rod 503 by the first limit block 504, and the first pull rod 503 drives the first rack 501 to move outward, and the first rack 501 squeezes the first spring 502, and the first spring 502 is compressed, and then the first limit block 504 is pushed inward to insert the first limit block 504 into the groove at the end of the first pull rod 503. At this time, the first rack 501 is no longer engaged with the first gear 303, and the lock on the first gear 303 is released, and the first rotating wheel 301 is rotated, and the first rotating wheel 301 drives the first transmission shaft 302, and the first transmission shaft 302 drives the first gear 303 to rotate, and the first gear 303 is released. The second gear 304 is driven to rotate through meshing, the second gear 304 drives the second transmission shaft 305 to rotate, the second transmission shaft 305 drives the turntable 306 to rotate, the turntable 306 drives the first connecting rod 307 to move, the first connecting rod 307 drives the propulsion slider 308 to make a linear motion in the slide rail 309, the propulsion slider 308 drives the second connecting rod 310 to move, the second connecting rod 310 drives the roller bracket 311 to move, the roller bracket 311 drives and guides the slider 314 to make a linear motion in the slide groove on the frame 1, the roller bracket 311 drives the third roller 103 to make a linear motion, and the left and right movement of the third roller 103 is used to adjust the tension of the conveyor belt 2.

[0044] After the third roller 103 is adjusted to a suitable position, the first limit block 504 is pulled outward, the first spring 502 rebounds, and the spring drives the first rack 501 to move into the first protection box, the first rack 501 engages with the first gear 303, and pushes the first limit block 504 inward, so that the first limit block 504 is inserted into another groove of the first pull rod 503 to complete the locking of the first gear 303; the second rotating wheel 401 is rotated clockwise, the second rotating wheel 401 drives the third transmission shaft 402 to rotate clockwise, the third transmission shaft 402 drives the third gear 403 to rotate clockwise, the third transmission shaft 402 drives the fourth gear 404 to rotate clockwise, and the fourth gear 404 drives the third gear 303 to rotate clockwise through meshing. The second rack 405 makes a linear motion to the left, and the second rack 405 drives the rotating wheel 406 to rotate, and the rotating wheel 406 drives the two third connecting rods 407 to rotate towards each other, and the third connecting rod 407 drives the clamping block 408 to close, thereby completing the clamping of the second transmission shaft 305; at this time, the second limit block 508 is pulled outward again, so that the second limit block 508 slides out of the groove at the end of the second pull rod 507, and the second spring 506 rebounds, and the second spring 506 drives the third rack 505 to move, and the third rack 505 meshes with the third gear 403, and then the second limit block 508 is pushed inward so that the second limit block 508 is inserted into another groove of the second pull rod 507 to complete the locking of the third gear 403.

[0045] When the conveyor belt 2 at the first roller 101 at one end of the frame 1 deviates, the edge of the conveyor belt 2 pushes the toggle rod 601 outward to move the other end of the fourth connecting rod 602 toward the inside of the frame 1, the fourth connecting rod 602 drives the fifth connecting rod 604 to rotate and squeeze the torsion spring, the fifth connecting rod 604 drives the push block 605 to move toward one side of the first roller 101, the push block 605 pushes the edge of the conveyor belt 2 to return to the original track, and the toggle mechanism 6 can be reset under the action of the torsion spring rebound force. The baffles 106 on both sides of the first roller 101 at the other end of the frame 1 continuously provide guiding force to the conveyor belt 2 to prevent the conveyor belt 2 from deviating.

[0046] According to the principle that the conveyor belt 2 runs tight but not loose, the second roller 102 and the third roller 103 both adopt a drum-shaped design with a large diameter in the middle and small diameters at both ends. The length of each small diameter portion is one fifth of the total length of the roller. The design of the drum roller can make the contact between the roller and the conveyor belt 2 or the working surface more uniform, reducing wear and deformation caused by uneven force. In the conveying equipment, the drum roller can achieve slight squeezing and guiding of the material, making the material more stable and less likely to deviate during the conveying process.

[0047] Each hydraulic cylinder 108 is connected to a hydraulic station, and the overall conveyor can be electronically controlled to complete lifting operations to meet the conveying requirements of different heights and positions.

[0048] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions 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.
