Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic deviation-correcting device for a tubular belt conveyor. Background Art

[0002] In the process of transporting materials, the tubular belt conveyor is often subjected to uneven pressure due to environmental reasons such as heavy goods or uneven distribution, as well as installation errors and friction resistance of the tubular belt conveyor rollers. This can easily cause the tubular conveyor belt to deflect and deviate from the center line of the conveyor, causing material to be scattered along the line and reducing the conveyor's material transportation capacity. In severe cases, the belt will be damaged and the conveyor will be unable to work. Therefore, it is necessary to correct the deviation of the tubular conveyor belt of the tubular belt conveyor.

[0003] For example, the patent with the announcement number CNA discloses an automatic deviation correction system for tubular belt twisting and its convenient use method. In the prior art, after the deviation of the tubular conveyor belt is detected by the sensor, the metal shell with a metal wheel is driven by a motor to rotate and toggle the upper and lower ends of the conveyor belt curled into a tubular shape. The metal wheel is parallel to the axis of the tubular conveyor belt. While the metal wheel is attached to the tubular conveyor belt and rolling, the metal wheel is driven by the rotation of the metal shell to toggle the tubular conveyor horizontally to restore the deviation. However, the contact surface between the metal wheel and the tubular conveyor belt is limited, and the tubular conveyor belt carries heavy objects inside. The metal wheel only acts on one point on the tubular conveyor belt, resulting in limited correction effect of the metal wheel on the toggle rotation of the tubular conveyor belt carrying heavy objects.

[0004] Therefore, an automatic deviation-correcting device for a tubular belt conveyor is introduced. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 3 and Fig. 9, an automatic deviation-correcting device for a tubular belt conveyor comprises a base 1 and a first mounting seat 2 fixedly connected to the two ends of the top of the base 1, a second mounting seat 3 is fixedly connected to the top of the base 1 between the first mounting seats 2 at uniform intervals, a fixing plate is fixedly connected to the top of the two ends of the base 1 on both sides, a driving roller 11 is movably arranged between the side walls at the top of the fixing plate, the first mounting seat 2 is arranged close to the driving roller 11, a rotating motor fixedly connected to the driving roller 11 is arranged on the side wall of the fixing plate at one end of the base 1, a circular first through hole 21 and a second through hole 22 are respectively opened on the first mounting seat 2 and the second mounting seat 3, a tubular conveyor belt 12 (its tube diameter, i.e., the diameter of the conveyor belt after being rolled into a tube, is about 300 mm, the bandwidth, i.e., the width of the conveyor belt in the unfolded state, is 800 mm, and its thickness is 12 mm) is movably engaged in the first through hole 21 and the second through hole 22, and the two ends of the tubular conveyor belt 12 are respectively flattened and movably sleeved on the outer wall of the driving roller 11 The middle section of the tubular conveyor belt 12 is curled into a cylindrical shape and then movably inserted into the first through hole 21 and the second through hole 22 on the first mounting seat 2 and the second mounting seat 3. The first through hole 21 and the second through hole 22 on the first mounting seat 2 are coaxially arranged in a one-to-one correspondence with the first through hole 21 and the second through hole 22 on the second mounting seat 3, respectively. The side walls of the first mounting seat 2 and the second mounting seat 3 at the edge of the first through hole 21 and the second through hole 22 are evenly and fixedly connected with mounting frames 23 (which are composed of a fixed base plate and L-shaped arms installed at both ends of the outer wall of one side of the fixed base plate). Rollers 24 are movably arranged between the side walls of the mounting frames 23. The rollers 24 lift and limit the tubular conveyor belt 12 that passes through the first through hole 21 and the second through hole 22, so that the middle section of the tubular conveyor belt 12 always remains in a curled and closed state, thereby reducing dust generated when the tubular conveyor belt 12 transports bulk materials, which is conducive to maintaining a favorable and safe working environment at the transportation construction site.

[0031] The rollers 24 are evenly spaced and distributed in an inverted triangle shape and are suspended on the outside of the first through hole 21 and the second through hole 22. The rollers 24 at the lower sides of the first through hole 21 and the second through hole 22 are used to lift the tubular conveyor belt 12 to ensure that the curled cylindrical shape rolls on the rollers 24. The first mounting seat 2 and the second mounting seat 3 are respectively fixedly connected to the corners at both ends of the top of the beam angle iron 4, and a fixing rod 41 is fixedly connected between the side walls of the beam angle iron 4 adjacent to the first mounting seat 2. Auxiliary curling members 42 are respectively fixedly connected on both sides of the bottom of the fixing rod 41. The auxiliary curling members 42 are symmetrically suspended on both sides of the first through hole 21 on the first mounting seat 2, and the auxiliary curling members 42 are suspended on the outside of the rollers 24.

[0032] The auxiliary curling member 42 includes a U-shaped groove plate 421 fixedly connected to both sides of the bottom of the fixed rod 41, a positioning shaft 422 is movably provided between the inner walls of the U-shaped groove plate 421 near the bottom, a sector gear 423 is fixedly connected to the outer wall of the positioning shaft 422, the end of the sector gear 423 is movably connected to an extrusion roller 424, an electric lifting rod 425 is fixedly connected to the bottom of the fixed rod 41 inside the sector gear 423, and a rack 426 is fixedly connected to the bottom of the electric lifting rod 425, the rack 426 is meshed with the sector gear 423, and the rack 426 is meshed with the sector gear 423. Limiting strips 427 are fixedly connected to the outer walls on both sides respectively, and sliding grooves 428 are opened on the outer walls on both sides of the U-shaped groove plate 421 corresponding to the limiting strips 427. The ends of the limiting strips 427 are movably engaged in the sliding grooves 428, and the electric lifting rods 425 are telescopically moved up and down, thereby pushing the rack 426 to engage and drive the sector gear 423 to deflect, so that the extrusion roller 424 at the end of the sector gear 423 presses down and bends the edges of both ends of the tubular conveyor belt 12 that is about to pass through the first through hole 21, so that it forms a closed cylinder between the triangular suspended rollers 24.

[0033] In order to solve the problem that when the existing deviation correction device uses a metal wheel and a metal shell to rotate and correct the tubular conveyor belt, the contact area between the metal wheel and the tubular conveyor belt is limited and the force is concentrated on one point of the tubular conveyor belt, resulting in the metal wheel's unsatisfactory correction effect on the tubular conveyor belt carrying heavy objects. Figure 1-Figure 6 , provide the following preferred technical solutions:

[0034] A visual sensor 25 (model MV-LDX8030M-12S) is fixedly connected to the outer wall of one side of the first mounting seat 2 above the first through hole 21. The visual sensor 25 is arranged on the outer wall of the first mounting seat 2 away from the roller 24, and the visual sensor 25 is located at the vertical center line of the first through hole 21. The curling coincidence line of the edges at both ends of the tubular conveyor belt 12 is located directly above the center line of the first mounting seat 2. The visual sensor 25 is used to detect whether the curling coincidence line of the edges at both ends of the tubular conveyor belt 12 is offset from the center line of the first mounting seat 2 to determine whether it is offset; an installation cavity 26 connected to the first through hole 21 is arranged inside the first mounting seat 2, and a correction mechanism 5 is arranged on the inner wall of the installation cavity 26 at the first through hole 21.

[0035] The deviation correcting mechanism 5 comprises a worm gear ring 51 and a positioning cylinder 52 fixedly connected to an outer wall of one side of the worm gear ring 51, the end of the positioning cylinder 52 is rotatably connected to an inner wall of one side of the mounting cavity 26 at the first through hole 21, an L-shaped plate 53 is fixedly connected to the top of the worm gear ring 51, a suspension rope 511 is fixedly connected to the side wall at the bottom of the worm gear ring 51, a sleeve 512 is fixedly connected to the end of the suspension rope 511, a binding rope 54 is movably sleeved in the sleeve 512, both ends of the binding rope 54 are fixedly connected to the lower end of the top plate of the L-shaped plate 53, and auxiliary balls 55 are evenly sleeved on the outer walls of the binding rope 54 on both sides of the sleeve 512, an electric push rod 56 is fixedly connected to the lower end of the top plate of the L-shaped plate 53, and a limit plate 57 is fixedly connected to the bottom of the electric push rod 56, and both ends of the limit plate 57 are movably sleeved on the outer walls of the two ends of the binding rope 54, and one end of the worm gear ring 51 is threadedly connected to a driving rod 6, and the top end of the driving rod 6 is movably arranged through the top plate of the mounting cavity 26.

[0036] The driving rod 6 includes a transmission rod 61 that is movably arranged on the top plate of the installation cavity 26 and a worm 62 that is fixedly connected to the bottom of the transmission rod 61. A driving motor is fixedly connected to the top of the first mounting seat 2 corresponding to the transmission rod 61. The top of the transmission rod 61 is connected to the output end of the driving motor. The worm 62 is suspended on the outside of the worm gear ring 51, and the worm 62 is meshed with the teeth on the outer wall of one side of the worm gear ring 51. The teeth are symmetrically distributed on the outer walls of both sides of the worm gear ring 51 about the L-shaped plate 53.

[0037] Specifically, the tubular conveyor belt 12 carries the material and moves on the rollers 24 on the first mounting seat 2 and the second mounting seat 3. When passing through the first through hole 21 on the first mounting seat 2, the worm ring 51 in the mounting cavity 26 on the first mounting seat 2 carries the binding rope 54 to the outside of the tubular conveyor belt 12, and the visual sensor 25 detects whether the center line of the curled and overlapped edges at both ends of the tubular conveyor belt 12 deviates from the vertical center line of the first through hole 21, thereby determining whether the tubular conveyor belt 12 is offset. When offset occurs, the electric push rod 56 is extended to push the limit plate 57 to slide along the binding rope 54, and the limit plate 57 reduces the clearance around the binding rope 54 so that it binds and locks the tubular conveyor belt 12. At the same time, the limit plate 57 tightens and fits the loose auxiliary balls 55 on both sides of the binding rope 54. The tightly attached auxiliary balls 55 are tightened when the binding rope 54 is tightened. The locking buckle fits the outer wall of the tubular conveyor belt 12, and the tubular conveyor belt 12 can roll between the auxiliary balls 55 on the surrounding binding rope 54, ensuring the normal operation of the tubular conveyor belt 12 when it is corrected. At the same time, the auxiliary balls 55 that are tightly attached to each other are deformed to a certain extent. After the deformation, the auxiliary balls 55 fully fit the outer wall of the tubular conveyor belt 12 along the outer diameter. At the same time, the limit plate 57 restricts the auxiliary balls 55 from sliding along the binding rope 54, so that when the rotating motor controls the transmission rod 61 to drive the worm 62 to engage the worm gear ring 51 for transmission, the worm gear ring 51 is pushed to control the binding rope 54 to cooperate with the auxiliary balls 55 to stably and tightly fit the locking tubular conveyor belt 12 to quickly deflect left and right to a certain extent, thereby automatically adjusting the angle of the tubular conveyor belt 12 so that the tubular conveyor belt 12 automatically resets after being offset, ensuring the safety and convenience of the tubular conveyor belt 12 during operation.

[0038] In order to further enhance the stability of the auxiliary ball 55 pushing the tubular conveyor belt 12 to rotate and correct the deviation, Figure 5-Figure 8 As shown, this embodiment provides the following technical solutions:

[0039] The auxiliary ball 55 comprises a shell 5501 and a middle hole 5502 which is set through the center of the shell 5501. The shell 5501 is evenly sleeved on the outer wall of the restraining rope 54 through the middle hole 5502. The outer wall of the shell 5501 perpendicular to the axis of the middle hole 5502 is evenly spaced with mounting grooves 551. A convex thorn wave plate 552 is movably engaged in the mounting groove 551. The outer crest of the convex thorn wave plate 552 is a component made of flexible material. A plurality of thorns are staggered on the outer wall of the crest. The two ends of the outer wall of the convex thorn wave plate 552 close to the center of the shell 5501 are respectively movably connected with sliding deflection rods 553. The sliding deflection rod 553 is movably connected to the outer wall of the convex thorn wave plate 552. The ends of the housing 5501 are arranged in contact with the bottom plate of the mounting groove 551, and the edges of both ends of the housing 5501 on both sides of the mounting groove 551 are evenly spaced with air-filled cavities 554, an inner wall of the air-filled cavity 554 close to the mounting groove 551 is fixedly connected with an inclined spring piece 555, an outer wall of the inclined spring piece 555 close to the mounting groove 551 is movably connected with a touch rod 556, a torsion spring 557 is arranged between the touch rod 556 and the side wall of the fixed end of the inclined spring piece 555, a traction rope 558 is fixedly connected to the outer wall of the end of the touch rod 556, and the end of the traction rope 558 extends through the interior of the mounting groove 551 and is fixedly connected to the side wall of the sliding deflection rod 553.

[0040] An elastic component is fixedly connected between the side wall of the sliding deflection rod 553 and the inner wall of the mounting groove 551, and a roller that fits the bottom plate of the mounting groove 551 is provided at the end of the sliding deflection rod 553. When the elastic component is normally expanded, the convex wavy plate 552 contracts in the mounting groove 551. At this time, the sliding deflection rods 553 at both ends of the inner side of the convex wavy plate 552 are arranged in an eight-shaped shape.

[0041] The ends of the traction ropes 558 inserted into the two sides of the installation groove 551 are cross-fixed on the side walls of the sliding deflection rods 553 on both sides of the installation groove 551, and the ends of the inclined spring sheets 555 are suspended to fit the inner wall of the inflation cavity 554 away from the side of the installation groove 551. At this time, the end of the touch rod 556 is tilted downward to rest against the inner wall of the other side of the inflation cavity 554.

[0042] Specifically, after the limiting plate 57 slides along the restraining rope 54 so that the auxiliary balls 55 on both sides thereof fit and tighten, adjacent auxiliary balls 55 are squeezed against each other, so that the air-filled chambers 554 on both sides of the shell 5501 are squeezed and deformed against each other. After the air-filled chamber 554 is squeezed and deformed, its shell pushes the inclined spring piece 555 to elastically deform so as to approach the inner wall of the air-filled chamber 554 at the center of the shell 5501. After the end of the inclined spring piece 555 is deflected, the inner wall of the air-filled chamber 554 on the other side of the end of the touch rod 556 is caused to contract the torsion spring 557, so that the end of the touch rod 556 is deflected and moved toward the middle hole 5502 of the shell 5501. After the end of the touch rod 556 moves, it drives the traction rope 558 to be pulled and moved, and the traction rope 558 pulls the staggered pulling installation slot 5 The ends of the sliding deflection rods 553 on both sides of 51 move toward each other, thereby pushing the convex rib wave plate 552 to the end of the installation groove 551. When the auxiliary ball 55 cooperates with the binding rope 54 to bind and lock the tubular conveyor belt 12, the wave crest of the convex rib wave plate 552 fits the tubular conveyor belt 12 and deforms adaptively, so that the wave crest of the convex rib wave plate 552 pushes the thorns to limit the extrusion of the tubular conveyor belt 12 at different angles after deformation, so as to strengthen the radial friction force of the auxiliary ball 55 on the tubular conveyor belt 12 to a certain extent, thereby ensuring the stability of the binding rope 54 when pushing the auxiliary ball 55 to lock the tubular conveyor belt 12, so that the worm ring 51 can achieve stable rotation correction of the tubular conveyor belt 12, which is practical and convenient.
