A suspended conveyor mechanism for flange production

Abstract

This invention relates to the field of flange suspension conveying equipment, specifically a suspension conveying mechanism for flange production. It includes a support plate, a conveying track fixedly mounted on the bottom of the support plate, and a suspension bracket slidably disposed inside the conveying track. In this suspension conveying mechanism for flange production, when the wear of the guide wheel reaches a preset threshold, the shaft sinks accordingly. A pressure relief trigger mechanism drives the main guide plate and the guide plate to unfold sequentially, forming a ring structure coaxial with the shaft. Its outer edge can contact the inner wall of the conveying track, thus working together with the worn guide wheel to bear the load. The sliding contact between its outer edge and the inner wall of the conveying track fills the radial gap caused by guide wheel wear, automatically compensating for the sinking and tilting of the suspension bracket caused by the reduced radius and uneven wear of the guide wheel. This significantly reduces the lateral shaking and longitudinal vibration of the suspension rod, preventing flange workpieces from colliding, scratching, or deforming due to violent shaking.

Description

Technical Field

[0001] This invention relates to the field of flange suspension conveying equipment, specifically a suspension conveying mechanism for flange ring production. Background Technology

[0002] In mass production, flange rings are often transported continuously using overhead conveyor mechanisms. A typical mechanism includes a support plate, conveyor track, suspension bracket, chain, and sprockets. The suspension bracket is fixed to the chain by connecting pins, and a shaft is mounted on top. Guide wheels are located at both ends of the shaft, rolling along the inner wall of the track. The flange ring is suspended at the bottom. A drive motor drives the sprockets, causing the chain to circulate, which in turn moves the suspension bracket and guide wheels, completing the flange ring transport.

[0003] Over time, friction and wear will occur between the guide wheels and the inner bottom surface of the track. As wear increases, the rolling radius of the guide wheels decreases, causing the shaft center to shift downwards, resulting in the suspension bracket and flange ring sinking vertically. If the guide wheels on both sides wear unevenly or the wheel rims wear unevenly, it will also cause lateral shaking and longitudinal vibration, leading to the flange rings colliding with each other, surface scratches or deformation, while also aggravating fatigue damage to components such as chains and shafts, reducing the life and stability of the conveyor line.

[0004] The following problems exist in the existing technology that have not been well resolved: 1. The inspection cycle is difficult to determine accurately. If the inspection interval is too long, the excessive wear of the guide wheel will not be discovered until then. At this time, the suspension bracket has been in a state of vibration for a long time, which will have an irreversible impact on the quality of the flange ring and the life of the equipment; 2. The existing conveying mechanism lacks the ability to detect and compensate for wear. It cannot automatically take temporary guiding measures to suppress vibration in the early stage of wear of the guide wheel, nor can it provide real-time marking and prompting of wear positions, resulting in a lag in maintenance response. Summary of the Invention

[0005] The purpose of this invention is to provide a suspended conveying mechanism for flange production, thereby solving the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a suspended conveying mechanism for flange production, comprising a support plate, a conveying rail fixedly installed at the bottom of the support plate, a suspension bracket slidably disposed inside the conveying rail, and a shaft rotatably disposed on the upper part of the suspension bracket, which slides along the inner wall of the conveying rail, and guide wheels detachably mounted at both ends of the shaft;

[0013] The main guide groove and the secondary guide groove are respectively designed as L-shaped inclined groove structures, and the main guide groove and the secondary guide groove are set in the same oblique direction and the inclined sections are arranged one after the other.

[0014] Preferably, a spring return rod is symmetrically fixedly connected to the surface of the shaft, and one end of the spring return rod is fixedly connected to the side wall of the drive ring;

[0015] A connecting ring is rotatably provided on the side of the drive ring away from the spring return rod. A hinge block is symmetrically fixedly connected to the surface of the connecting ring, and two hinge plates are respectively hinged to the middle position of the two hinge blocks.

[0016] Preferably, the pressure relief triggering mechanism includes: air storage cylinders symmetrically and fixedly connected to both sides of the suspension bracket, and a piston rod is slidably provided on the upper part of the inner wall of the air storage cylinder, and the upper end of the piston rod extends into the inside of the conveying track and is fixedly connected to an arc-shaped plate that drives the hinge plate to move.

[0017] A conical vent sleeve for sealing is slidably installed at the bottom of the air storage cylinder, and a pad is fixedly connected to the bottom of the conveying track to restrict the downward movement of the conical vent sleeve;

[0018] A pad is fixedly installed at the bottom of the gas storage tank. A limiting rod that restricts the repositioning of the conical vent sleeve is slidably provided in the middle of the pad. An alarm light is fixedly installed on the surface of the pad. A pull rope that drives the alarm light to turn on is fixedly connected to the surface of the limiting rod. A compression spring is fixedly connected between the surface of the limiting rod and the side wall of the pad.

[0019] Preferably, a compression leaf spring is fixedly connected between the inner top surface of the air storage cylinder and the surface of the piston rod, and a stop block is fixedly connected to the inner wall of the air storage cylinder to restrict the piston rod from rising.

[0020] The inner bottom surface of the gas storage cylinder is conical, and a conical sealing gasket is fixedly connected to the upper part of the conical vent sleeve. A return spring is provided between the top of the conical vent sleeve and the bottom of the piston rod. The conical vent sleeve is cylindrical in shape, and an exhaust hole is opened on the surface of the conical vent sleeve.

[0021] An air inlet is fixedly connected to the lower part of the gas storage cylinder for replenishing gas inside the cylinder.

[0022] Preferably, a micro switch electrically connected to the alarm light is fixedly connected inside the pad, and the end of the pull rope away from the limit rod is fixedly connected to the swing arm of the micro switch.

[0023] Preferably, sprockets are rotatably arranged around the bottom of the support plate, and chains are movably installed between the four sprockets. The upper part of the suspension bracket is fixedly connected to the connecting pins corresponding to the chains.

[0024] A drive motor is fixedly connected inside the support plate, and the movable end of the drive motor is fixedly connected to the axis of the adjacent sprocket.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In this invention, by setting a temporary guiding mechanism, when the wear of the guide wheel reaches a preset threshold, the shaft sinks accordingly. The pressure relief triggering mechanism drives the main guide plate and the secondary guide plate to unfold sequentially and form a ring structure coaxial with the shaft. Its outer edge can contact the inner wall of the conveying track, thereby cooperating with the worn guide wheel to bear the load. Its outer edge slides in contact with the inner wall of the conveying track, thereby filling the radial gap caused by the wear of the guide wheel, automatically compensating for the sinking and tilting of the suspension bracket caused by the reduction of the guide wheel radius and uneven wear, significantly reducing the lateral shaking and longitudinal vibration of the suspension rod, and avoiding the flange workpiece from colliding with each other, scratching the surface or deforming due to violent shaking.

[0027] In this invention, by utilizing the fit between the air storage cylinder, the conical vent sleeve, and the bottom pad of the conveying track, the wear of the guide wheel is directly converted into the axial displacement of the conical vent sleeve. When the wear exceeds the preset distance between the pad and the conical vent sleeve, the conical vent sleeve is squeezed back by the pad and the seal is released, allowing the gas inside the air storage cylinder to be discharged through the exhaust hole. Then, the piston rod and the hinge plate are driven to move by the compression leaf spring. This triggering method is entirely based on mechanical wear self-detection, without the need to install additional sensors or electrical detection components. It is reliable and unaffected by harsh environments such as dust and oil.

[0028] In this invention, after the conical vent sleeve moves upward, the limiting rod, under the action of the compression spring, inserts into the limiting step at the lower part of the conical vent sleeve, restricting its reset and ensuring the stable discharge of gas inside the gas storage cylinder. This maintains the fully deployed state of the temporary guide mechanism. At the same time, the limiting rod drives the micro switch and illuminates the alarm light through the pull rope, providing an immediate indication of the suspension bracket workstation where the guide wheel needs to be replaced. This achieves self-locking after the compensation action, preventing the temporary guide mechanism from accidentally retracting due to the vent sleeve returning to its original position. It also provides maintenance personnel with clear guidance on the replacement location, shortening downtime for maintenance and improving production line maintenance efficiency.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 9 This invention provides a technical solution: a suspended conveying mechanism for flange production, comprising a support plate 1, a conveying track 2 fixedly mounted on the bottom of the support plate 1, a suspension bracket 3 slidably mounted inside the conveying track 2, and a shaft 4 rotatably mounted on the upper part of the suspension bracket 3, sliding along the inner wall of the conveying track 2, with guide wheels 5 detachably mounted at both ends of the shaft 4. It should be noted that: a suspension rod for suspending flanges is detachably mounted on the bottom of the suspension bracket 3; the top of the conveying track 2 is fixedly connected to the bottom of the support plate 1 via a support frame; a support bearing is fixedly connected between the middle of the shaft 4 and the inner wall of the suspension bracket 3, ensuring that the shaft 4 can rotate stably with the guide wheels 5; and a dust collector is installed at the inner ring of the conveying track 2, which can effectively suppress dust accumulation inside the conveying track 2. This dust collector is existing technology for flange suspended conveying and will not be described in detail.

[0041] It also includes: a temporary guide mechanism 6 that is movably mounted on the surface of the shaft 4, used to replace the guide wheel 5 for temporary guidance.

[0042] The pressure relief triggering mechanism 7 is mounted on the surface of the suspension bracket 3 to drive the operation of the temporary guide mechanism 6.

[0043] In this embodiment, as Figures 1 to 9As shown, the temporary guide mechanism 6 includes: a main guide plate 601 that is longitudinally slidably disposed on the surface of the shaft 4, and a secondary guide plate 602 that is laterally slidably disposed on the surface of the shaft 4. It should be noted that: there are two main guide plates 601 and two secondary guide plates 602, and the moving directions of the main guide plate 601 and the secondary guide plate 602 are both perpendicular to the axis of the shaft 4.

[0044] A main guide groove 603 is formed in the middle of the inner ring of the main guide plate 601, and a secondary guide groove 604 is formed in the middle of the inner ring of the guide plate 602. T-shaped guide rods 605 are slidably arranged inside both the main guide groove 603 and the secondary guide groove 604. A drive ring 606 that slides along the surface of the shaft 4 is fixedly connected between the ends of the four T-shaped guide rods 605. A hinge plate 607 that cooperates with the pressure relief trigger mechanism 7 is hinged to the side wall of the drive ring 606. It should be noted that: a ball bearing is fixedly connected to the inner ring of the drive ring 606, and the surface of the ball bearing overlaps with the surface of the shaft 4 to reduce the frictional resistance of the drive ring 606's movement; rounded corners are provided at the corners of both the main guide groove 603 and the secondary guide groove 604 to reduce the risk of jamming when the T-shaped guide rods 605 slide.

[0045] In this embodiment, as Figures 1 to 9 As shown, both the main guide plate 601 and the secondary guide plate 602 are arc-shaped plates, configured to expand outward and splice into a ring shape when driven. The ring's axis is coaxial with the axis of the shaft 4. Four limiting pins 611 are telescopically provided on the sidewall of the guide wheel 5, each corresponding to one of the two secondary guide plates 602 and the two main guide plates 601. It should be noted that the outer edges of the expanded main guide plate 601 and secondary guide plate 602 can contact the inner wall of the conveying track 2 (the specific dimensions can be adjusted according to the actual wear threshold, and are not limited here). For example, when the guide wheel 5 wears more than 2.5mm, to prevent uneven wear on both sides of the shaft 4, which could gradually increase the wear and cause vibration during the movement of the shaft 4 with the suspension bracket 3, the temporary guiding mechanism 6 drives the ring-shaped main guide plate 601 and secondary guide plate 602 to assist in guiding the worn guide wheel 5, preventing the suspended flange from shaking due to vibration. In the event of a collision, both the main guide plate 601 and the secondary guide plate 602 are inlaid with wear-resistant material layers such as copper alloy or polytetrafluoroethylene to reduce friction and wear when sliding in contact with the inner wall of the conveying track 2 and extend the effective time of temporary guidance. A compression spring is fixedly connected between the end of the limiting pin 611 and the inner wall of the guide wheel 5. When the main guide plate 601 and the secondary guide plate 602 are extended to their limit state, the limiting pin 611 extending from the side wall of the guide wheel 5 limits and locks them. Eight limiting pins 611 can be provided, with two provided at each position of the main guide plate 601 and the secondary guide plate 602 to ensure the stability of the limit.

[0046] Spring rods 608 are fixedly connected to both sides of the inner ring of the guide plate 602 and the main guide plate 601, with one end of the spring rod 608 fixedly connected to the inside of the shaft 4. It should be noted that the spring rods are of low tension and cannot interfere with the compression spring 710; they can only drive the main guide plate 601 and the guide plate 602 to move back to their original positions.

[0047] Grooves 609 are provided at the middle position of the inner ring of the guide plate 602 and the main guide plate 601, and the main guide groove 603 and the secondary guide groove 604 are provided on the inner wall of the corresponding groove 609.

[0048] The main guide groove 603 and the secondary guide groove 604 are both designed as L-shaped inclined groove structures, and the main guide groove 603 and the secondary guide groove 604 are set in the same inclined direction and the inclined sections are arranged sequentially. It should be noted that: the inclined trajectory of the secondary guide groove 604 is set to twice the length of the inclined trajectory of the main guide groove 603. When the T-shaped guide rod 605 of the main guide groove 603 slides, it first moves along the inclined trajectory and then moves along the horizontal trajectory, so that the main guide plate 601 expands outward and then remains in position; when the T-shaped guide rod 605 of the secondary guide groove 604 slides, it first moves along the horizontal trajectory and then moves along the inclined trajectory, so that after the main guide plate 601 expands into place, the secondary guide plate 602 then performs the expansion action, ensuring that the main guide plate 601 and the secondary guide plate 602 effectively form a ring-shaped expansion.

[0049] In this embodiment, as Figures 1 to 9 As shown, spring return rods are symmetrically fixedly connected to the surface of shaft 4, and one end of the spring return rod is fixedly connected to the side wall of drive ring 606. It should be noted that the spring return rod is a telescopic rod type. When the operator manually removes and replaces the worn guide wheel 5, the limit pin 611 releases the limit on the main guide plate 601 and the secondary guide plate 602. At this time, the spring return rod moves the drive ring 606 to reset.

[0050] A connecting ring 610 is rotatably mounted on the side of the drive ring 606 away from the spring return rod. Hinges are symmetrically fixed to the surface of the connecting ring 610, and two hinge plates 607 are respectively hinged to the middle positions of the two hinge blocks. It should be noted that the connecting ring 610 is rotatably connected to the drive ring 606 via a mounting bearing. When the drive ring 606 rotates with the shaft 4, the connecting ring 610 and the hinge plates 607 remain stationary to avoid interference.

[0051] In this embodiment, as Figures 1 to 9As shown, the pressure relief triggering mechanism 7 includes: air storage cylinders 701 symmetrically fixedly connected to both sides of the suspension bracket 3, and a piston rod 702 slidably disposed on the upper part of the inner wall of the air storage cylinder 701. The upper end of the piston rod 702 extends into the inside of the conveying track 2 and is fixedly connected to an arc-shaped plate 703 that drives the hinge plate 607 to move. It should be noted that: the upper part of the arc-shaped plate 703 is symmetrically provided with hinge slots, and the two hinge plates 607 are respectively hinged and disposed inside the two hinge slots; an inspection window is provided on the side wall of the conveying track 2 to facilitate maintenance and repair of damaged guide wheels 5 and other components.

[0052] A conical vent sleeve 704 for sealing is slidably installed at the lower part of the air storage cylinder 701. A pad 705 is fixedly connected to the bottom of the conveying track 2 to restrict the downward movement of the conical vent sleeve 704. It should be noted that the distance between the pad 705 and the conical vent sleeve 704 is set to 2.5mm. When the air storage cylinder 701 moves downward with the conical vent sleeve 704, the conical vent sleeve 704 is restricted and squeezed by the pad 705, causing it to move into the air storage cylinder 701 to achieve the venting operation. Both ends of the pad 705 are chamfered to facilitate the bottom of the conical vent sleeve 704 to make contact with the pad 705.

[0053] A pad 706 is fixedly installed at the bottom of the gas storage tank 701. A limiting rod 707 for resetting the conical vent sleeve 704 is slidably provided in the middle of the pad 706. An alarm light 708 is fixedly installed on the surface of the pad 706. A pull rope 709 for driving the alarm light 708 to open is fixedly connected to the surface of the limiting rod 707. A compression spring 713 is fixedly connected between the surface of the limiting rod 707 and the side wall of the pad 706. It should be noted that: the limiting rod 707 is T-shaped, and the side of the limiting rod 707 near the conical vent sleeve 704 is rectangular. The outer wall of the conical vent sleeve 704 is provided with a limiting step that cooperates with the limiting rod 707. When the conical vent sleeve 704 is restricted and squeezed upward into the gas storage cylinder 701 by the pad 705, the rectangular end of the limiting rod 707 will be locked into the limiting step at the bottom of the conical vent sleeve 704, restricting the conical vent sleeve 704 from resetting. This facilitates the compression spring 710 to drive the piston rod 702 downward to discharge the gas inside the gas storage cylinder 701.

[0054] In this embodiment, as Figures 1 to 9 As shown, a compression leaf spring 710 is fixedly connected between the inner top surface of the air reservoir 701 and the surface of the piston rod 702, and a stop block is fixedly connected to the inner wall of the air reservoir 701 to restrict the rise of the piston rod 702. It should be noted that the elastic force of the compression leaf spring 710 can effectively push the drive ring 606 to slide on the surface of the shaft 4 through the cooperation of the piston rod 702 and the hinge plate 607.

[0055] The inner bottom surface of the air reservoir 701 is conical. A conical sealing gasket is fixedly connected to the upper part of the conical vent sleeve 704. A return spring is provided between the top of the conical vent sleeve 704 and the bottom of the piston rod 702. The conical vent sleeve 704 is a cylindrical structure, and an exhaust hole 711 is opened on the surface of the conical vent sleeve 704. It should be noted that the elasticity of the return spring is less than that of the compression leaf spring 710, and it is only used for the reset of the conical vent sleeve 704. When the conical vent sleeve 704 moves down with the conical sealing gasket, it can cooperate with the inner bottom surface of the air reservoir 701 to perform a sealing treatment.

[0056] An air inlet is fixedly connected to the lower part of the air storage cylinder 701 for replenishing gas inside the air storage cylinder 701.

[0057] In this embodiment, as Figures 1 to 9 As shown, a micro switch 712, which is electrically connected to the alarm light 708, is fixedly connected inside the pad 706, and the end of the pull rope 709 away from the limit rod 707 is fixedly connected to the swing arm of the micro switch 712. It should be noted that when the limit rod 707 moves towards the conical vent sleeve 704, restricting the reset of the conical vent sleeve 704, the air tank 701 is in the venting operation. At this time, the limit rod 707 pulls the swing arm of the micro switch 712 via the pull rope 709, driving the alarm light 708 to open for warning. The cooperation between the micro switch 712 and the alarm light 708 is existing technology and will not be described in detail here.

[0058] In this embodiment, as Figures 1 to 9 As shown, sprockets 8 are rotatably mounted around the bottom of the support plate 1, and chains 9 are movably installed between the four sprockets 8. The upper part of the suspension bracket 3 is fixedly connected to the connecting pin of the corresponding chain 9.

[0059] A drive motor is fixedly connected inside the support plate 1, and the movable end of the drive motor is fixedly connected to the axis of the adjacent sprocket 8.

[0060] The method of use and advantages of this invention: The working process of this suspended conveying mechanism for flange production is as follows:

[0061] like Figures 1 to 9 As shown, in the working state, the drive motor drives the sprocket 8 to rotate, and the four sets of sprockets 8 drive the chain 9 to circulate along the track of the conveying track 2. During the operation of the chain 9, the connecting pin drives the shaft 4 and guide wheel 5 on the suspension bracket 3 to slide along the track of the conveying track 2, so that the suspension rod at the bottom of the suspension bracket 3 carries the flange to complete the conveying operation according to the preset path.

[0062] When the guide wheel 5 experiences excessive wear during use, the distance between the shaft center of the shaft 4 and the inner bottom surface of the conveying track 2 shifts. The shaft 4 then causes the air storage cylinder 701 to move downwards. When the lower conical vent sleeve 704 of the air storage cylinder 701 moves to the bottom pad 705 of the conveying track 2, under the limiting and pressing action of the pad 705, the conical vent sleeve 704 retracts into the inner cavity of the air storage cylinder 701. The sealing fit between its conical surface and the inner wall of the air storage cylinder 701 fails. At this time, the compression spring... Driven by 710, the piston rod 702 moves downward, and the gas inside the gas storage cylinder 701 is discharged through the exhaust hole 711 opened on the surface of the conical vent sleeve 704. The downward-moving piston rod 702 drives the hinge plate 607, which is hinged, to deflect through the arc plate 703. The hinge plate 607 pushes the drive ring 606 to move towards the guide wheel 5 on the same side. The drive ring 606 drives several T-shaped guide rods 605 on the side wall to slide along the corresponding main guide groove 603 and the trajectory of the guide groove 604.

[0063] When the T-shaped guide rod 605 in the main guide groove 603 section slides, it first moves along the inclined plane trajectory and then along the horizontal trajectory, so that the main guide plate 601 expands outward and remains in position. When the T-shaped guide rod 605 in the guide groove 604 section slides, it first moves along the horizontal trajectory and then along the inclined plane trajectory, so that after the main guide plate 601 expands to the position, the guide plate 602 performs the expansion action. After the two sets of main guide plates 601 and two sets of secondary guide plates 602 expand to form a ring structure, they stop moving. At the same time, the guide wheel 5 side wall limiting pin 611 limits and locks the main guide plate 601 and secondary guide plate 602 in place. The main guide plate 601 and secondary guide plate 602 arranged in a ring cooperate to assist the guide wheel 5 to achieve guidance and support. The outer diameter of the ring structure is the same as the diameter of the guide wheel 5 in the wear preset threshold state, so as to avoid the suspension rod shaking caused by the increased wear of the guide wheel 5, and thus prevent the flange from shaking and colliding.

[0064] After the conical vent sleeve 704 moves upward, the limiting rod 707 is inserted into the limiting step opened at the lower part of the conical vent sleeve 704 under the reset action of the compression spring 713, which restricts the resetting of the conical vent sleeve 704 and ensures stable gas depressurization inside the gas storage cylinder 701. At the same time, the displaced limiting rod 707 drives the micro switch 712 to act through the pull rope 709, triggering the alarm light 708 to light up and marking the position of the suspension bracket 3 to be replaced on the guide wheel 5.

[0065] When the guide wheel 5 is worn to the point of needing replacement and the temporary guide mechanism 6 has been triggered, the maintenance personnel manually pull the limit rod 707, causing its rectangular end to exit from the limit step of the conical vent sleeve 704. The conical vent sleeve 704 moves downward under the action of the return spring, and its conical sealing gasket re-fits with the inner bottom surface of the air tank 701, restoring the seal. Then, gas is added to the air tank 701 through the inflation nozzle to the preset pressure. Next, the worn guide wheel 5 is manually removed. After the guide wheel 5 is removed, the limit pin 611 releases the lock on the main guide plate 601 and the secondary guide plate 602. Then, after the lock is released, the elastic force of the spring return rod drives the drive ring 606 to move away from the guide wheel 5, causing the T-shaped guide rod 605 to slide in the opposite direction along the main guide groove 603 and the secondary guide groove 604, causing the main guide plate 601 and the secondary guide plate 602 to retract back to their initial positions. Finally, a new guide wheel 5 is installed. At this time, the entire mechanism is completely reset and can be put into use again.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
