Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a suspension conveying device and method for galvanizing of steel components. Background Art

[0002] The suspended conveyor is a commonly used continuous conveying equipment, which is widely used to continuously convey various products in the factory. It can also be used in the assembly lines of various industrial departments to convey workpieces between various processes, complete various process steps, and realize the comprehensive mechanization of conveying and process operations. Its structure mainly includes rails, traction chains, slides, trolleys, drive devices, tensioning devices and safety devices. The suspended conveyor is widely used and can also be adapted to the conveying and transfer work in the galvanizing processing of steel components, thereby improving the overall production efficiency.

[0003] A hanging conveying device disclosed in the patent with reference publication number CN111824690B is provided. The conveying device is formed by opening a gap in the second track and configuring a hanging assembly with a third track. The third track can be positioned in the gap or detached from the gap, and can be used to receive the transport vehicle transported from the second track, or return the transport vehicle to the second track, thereby realizing automatic detachment and transfer of the workpiece from the hanging conveying device, which is beneficial to improving assembly efficiency.

[0004] At present, most of the hanging conveying devices use cantilever and catenary to complete the transfer and transportation of products by articulating the hook with the mobile trolley of the conveying device. For example, the above conveying device also uses cantilever to complete the transfer and transportation of products, which improves the production efficiency. However, in actual operation, the cantilever and catenary cannot quickly complete the self-adaptation adjustment according to the product conveying height, and it is necessary to repeatedly disassemble and replace different cantilevers to complete the length control, which reduces the overall conveying efficiency and makes maintenance difficult.

[0005] Moreover, currently, most suspended conveying devices use a single cantilever to connect with the mobile trolley of the conveying equipment. In actual use, the cantilever is very likely to fall off, which is prone to safety accidents and poses a major safety hazard, which is not conducive to the safe and effective implementation of the conveying work.

DETAILED DESCRIPTION

[0062] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0063] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0064] Embodiment 1: The present invention provides a technical solution: Figure 1 , Figure 2 As shown, a suspension conveying device for galvanizing steel components includes a suspension guide rail 1, which is freely set to be a splicing composition of curved sections and straight sections according to the needs of the production line, and is dynamically adjusted according to the needs of the production line. A plurality of suspension arms are added to the suspension guide rail 1, and the suspension guide rail 1 is suspended in a conveying space by the plurality of suspension arms. The bottom of the suspension guide rail 1 is open, a guide rail chain 101 is arranged in the suspension guide rail 1, and a power source 102 is installed on the suspension guide rail 1 through a bracket. The power source 102 is connected to the guide rail chain 101 by transmission, so that the guide rail chain 101 moves in the suspension guide rail 1. Specifically, the power source 102 can use a driving motor, a sprocket and other transmission methods to complete the driving work, and an electric rod for completing the tension control of the guide rail chain 101 is installed on the suspension guide rail 1, and also includes:

[0065] A plurality of moving trolleys 103 are evenly distributed in the suspension rail 1 to complete the suspension conveying action. Each moving trolley 103 is connected to the rail chain 101 to complete the power connection, and the moving trolley 103 is in rotational contact with the suspension rail 1, and a connecting arm 104 is installed at the bottom of the moving trolley 103;

[0066] Multiple suspension mechanisms are correspondingly mounted on the connecting arms 104 of multiple mobile carts 103 to complete the product conveying work, and each suspension mechanism can be adjusted in length to adapt to the conveying requirements of different products;

[0067] Multiple protection mechanisms are evenly distributed and assembled on multiple suspension mechanisms for safety protection work. The number of the multiple protection mechanisms is consistent with the number of the multiple suspension mechanisms. Each protection mechanism is divided into a winding unit, a gravity locking unit and a centrifugal locking unit. The winding unit follows the suspension mechanism to synchronously complete the length adjustment work. The gravity locking unit senses the weight to lock the winding unit. The centrifugal locking unit senses the centrifugal force to lock the winding unit. The locking operation of the winding unit is completed by the gravity locking unit and the centrifugal locking unit.

[0068] Embodiment 2: Based on the suspension mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the suspension mechanism.

[0069] like Figure 3 , Figure 4 and Figure 5 As shown, each suspension mechanism includes:

[0070] The reel seat 2 is arranged at the bottom of the connecting arm 104. Specifically, the reel seat 2 is fixedly connected to the connecting arm 104 by welding, bolts, etc. The top and bottom of the reel seat 2 are both open in design. A reel shaft 3 is rotatably installed in the reel seat 2, and one end of the reel shaft 3 is rotatably passed through the reel seat 2. A reel disc 4 is fixedly sleeved on the outside of the reel shaft 3. A driving member 5 for driving the reel shaft 3 to rotate is fixedly installed at one end of the reel shaft 3. The driving member 5 is specifically a hand wheel, a motor, or other devices that can be used to complete the reel shaft 3. The device driven by the invention is used, and a ratchet pawl mechanism 6 is added between the winding shaft 3 and the winding seat 2, and the locking work of the winding shaft 3 is completed by the ratchet pawl mechanism 6. Specifically, a pawl is rotatably installed on one side of the winding seat 2 through a torsion spring, and a ratchet is fixedly sleeved on the outside of the winding shaft 3. The one-way locking of the winding shaft 3 is completed by the cooperation of the pawl and the ratchet, and the pawl can be freely operated and controlled to complete the opening and closing. Two No. 1 guide rollers are symmetrically rotatably installed at the bottom of the winding seat 2 to complete the rotation guidance of the suspension rope 7;

[0071] The hanging rope 7 is wound on the winding drum 4 to complete the length control. A counterweight hook 12 is installed at the bottom of the hanging rope 7, and a product rack is hung on the counterweight hook 12;

[0072] It is worth mentioning that: when adjusting the height of the hanging conveyor: by providing a hanging mechanism, under normal circumstances, the ratchet pawl mechanism 6 locks the winding shaft 3, so that the winding disk 4 and the suspension rope 7 remain stable and are in a stable hanging conveying state. When adjusting, it is only necessary to control the pawl to separate from the ratchet wheel, and then operate the driving member 5 to drive the winding shaft 3 to rotate to complete the winding and release of the suspension rope 7 thereon, so as to complete the targeted length adjustment, and can be adjusted according to different conveying environments, making the overall hanging conveying work more flexible and adaptable, reducing the difficulty of maintenance, and facilitating the operator to adjust and use.

[0073] Embodiment 3: Based on the protection mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the protection mechanism.

[0074] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the winding unit comprises:

[0075] The shaft seat 8 is arranged on one side of the winding seat 2. Specifically, the shaft seat 8 and the winding seat 2 are detachably fixedly connected by bolts, etc. A winding shaft 9 is rotatably installed in the shaft seat 8. A winding disk 10 is fixedly sleeved outside the winding shaft 9. A protective rope 11 is wound on the winding disk 10. The bottom of the protective rope 11 is connected to one side of the counterweight hook 12 for safety protection. The protective rope 11 and the suspension rope 7 are both pulled by aramid rope, nylon rope and carbon fiber rope, which is conducive to winding adjustment and can also provide high-strength supporting force. Two No. 2 guide rollers are symmetrically rotatably installed at the bottom of the shaft seat 8 to guide the rotation of the protective rope 11;

[0076] Two lifting areas 13 are symmetrically arranged on both sides of the shaft seat 8, and lifting platforms 14 are slidably engaged in the two lifting areas 13. Locking areas 15 are arranged in the two lifting platforms 14, and the winding shaft 9 rotates correspondingly through the two lifting platforms 14. A pulling spring 16 is installed between the lifting platform 14 and the top of the lifting area 13. The lifting platform 14 is pulled by the pulling spring 16 to reset and move toward the top of the lifting area 13, and a fixed block is installed in the lifting area 13 to limit the lifting platform 14 and prevent it from being over-reset;

[0077] The winding unit also includes:

[0078] The connecting shaft 17 is rotatably mounted on one side of the winding seat 2 for power transmission, and the connecting shaft 17 is drivingly connected to the winding shaft 3, and the connecting shaft 17 is connected to the shaft seat 8 through a bracket, and a first gear 18 is fixedly sleeved on one end of the connecting shaft 17;

[0079] The second gear 19 is rotatably mounted on one side of the shaft seat 8 and meshes with the first gear 18 for transmission. A third gear 20 meshes with the second gear 19 for transmission is fixedly sleeved on one end of the winding shaft 9, and the third gear 20 can be separated from the second gear 19.

[0080] It is worth noting that: when the length adjustment is completed by following the suspension unit: by providing a winding unit, under normal conditions, the two lifting platforms 14 are reset to the initial position in the lifting area 13 through the pulling action of the pulling spring 16, so that the No. 3 gear 20 moves up and meshes with the No. 2 gear 19, at this time, the No. 1 arc gear plate 23 and the No. 2 arc gear plate 27 are separated from the locking gear ring 21, and the winding shaft 9 is in an unlocked state and can complete free rotation. Therefore, when operating the winding shaft 3, the power is transmitted to the No. 1 gear 18 through the connecting shaft 17, and the No. 3 gear 20 is driven to rotate through the No. 2 gear 19, so that the winding shaft 9 follows the winding shaft 3 to complete the synchronous winding and releasing action, without the need to perform secondary adjustment of the protection rope 11, and the operation is more convenient, so that the protection rope 11 and the suspension rope 7 can be kept in synchronous adjustment and use, and the height difference between the two is avoided to interfere with the operation of the suspension mechanism;

[0081] like Fig.10 ,like Fig.11 As shown, in the embodiment of the present invention, the gravity locking unit includes:

[0082] Two locking gear rings 21 are fixedly sleeved on both ends of the winding shaft 9 and hidden in the two locking areas 15;

[0083] Two moving areas 22 are correspondingly slidably opened in the two locking areas 15;

[0084] Two arc-shaped tooth plates 23 are correspondingly slidably mounted on the bottom of the two locking areas 15, and the two arc-shaped tooth plates 23 are correspondingly slidably engaged with the bottom of the two moving areas 22, and the gravity locking action is completed by the engagement of the arc-shaped tooth plates 23 and the locking gear ring 21;

[0085] The gravity locking unit comprises:

[0086] Two sensing arms 24 are correspondingly arranged at the bottom of the two first arc-shaped tooth plates 23. The bottoms of the two sensing arms 24 are both slidably arranged through the bottom of the lifting platform 14. The outsides of the two sensing arms 24 are fixedly sleeved with fixed retaining rings 25. A return spring 26 is installed between the fixed retaining ring 25 and the lifting platform 14. The return spring 26 is correspondingly sleeved on the outside of the sensing arms 24. The first arc-shaped tooth plate 23 is pulled toward the bottom of the locking area 15 by the return spring 26.

[0087] The gravity locking unit also includes:

[0088] Two second arc-shaped tooth plates 27 are correspondingly slidably mounted on the top of the two locking areas 15, and the two second arc-shaped tooth plates 27 are correspondingly slidably engaged with the top of the two moving areas 22. At the same time, a third spring can be added between the second arc-shaped tooth plates 27 and the moving area 22 to assist the second arc-shaped tooth plates 27 in resetting.

[0089] Two conversion gears 28 are correspondingly mounted in rotation at the middle position of the two moving areas 22. A first rack 29 is meshed and mounted on one side of the conversion gear 28, and the first rack 29 is connected to the first arc-shaped toothed plate 23. A second rack 30 is meshed and mounted on the other side of the conversion gear 28, and the second rack 30 is connected to the second arc-shaped toothed plate 27. The multiple locking work is completed by the meshing of the second arc-shaped toothed plate 27 and the locking gear ring 21.

[0090] It is worth noting that: when gravity sensing protection is performed: by providing a gravity locking unit, while the centrifugal locking unit is working, the weight of the counterweight hook 12, the electroplating rack and the products thereon are also transferred to the protection rope 11. At this time, the winding shaft 9 senses the falling weight, quickly overcomes the pulling of the pulling spring 16 and moves downward in the lifting area 13, so that the sensing arm 24 follows the downward movement and contacts the bottom of the lifting area 13, and compresses the reset spring 26, so that the sensing arm 24 drives the first arc-shaped tooth plate 23 to move upward in the locking area 15 and contact the locking tooth plate. The ring 21 is engaged and in contact, thereby completing the multiple locking effect. In order to further enhance the locking effect, when the No. 1 arc-shaped tooth plate 23 moves upward, the No. 1 rack 29 is synchronously linked to move, and driven by the conversion gear 28, so that the No. 2 rack 30 completes the follow-up movement, and the No. 2 arc-shaped tooth plate 27 is linked to move downward and engage with the locking gear ring 21, further enhancing the locking performance, and can complete adaptive locking according to the weight of the product to avoid the problem of falling off, which can ensure the safe progress of transportation work, reduce the accident rate, and reduce the risk of transportation;

[0091] like Fig.12 , Fig.13 and Fig.14 As shown, in the embodiment of the present invention, the centrifugal locking unit includes:

[0092] A locking ring 31 is arranged on one side of one of the lifting platforms 14 for completing locking. The locking ring 31 is connected to the lifting platform 14 through a bracket, and the locking ring 31 is arranged concentrically with the winding shaft 9. An inner gear ring 32 is arranged inside the locking ring 31;

[0093] A plurality of locking arms 33 are arranged in a circular array at one end of the winding shaft 9 to contact the locking ring 31 to complete the locking work. Each locking arm 33 includes a sliding frame 331 and a gravity arm 332. The sliding frame 331 is fixedly installed on the winding shaft 9. The sliding frame 331 is open all around. The gravity arm 332 is slidably installed in the sliding frame 331. The gravity arm 332 adopts a counterweight design and can sense the centrifugal force to complete the locking work. The weight of the gravity arm 332 is changed according to the use environment to obtain a precise locking effect, and the front end of the gravity arm 332 slides through the top of the sliding frame 331.

[0094] A plurality of locking tooth plates 333 are integrally fixed to the front end of the gravity arms 332 of the plurality of locking arms 33. The locking work is completed by the engagement of the locking tooth plates 333 with the inner gear ring 32. The number and density of teeth of the locking tooth plates 333 and the inner gear ring 32 can be freely adjusted and set according to actual needs to obtain a good locking state. The locking tooth plates 333 adopt an arc design;

[0095] A plurality of No. 1 springs 334 are disposed between the gravity arms 332 of the plurality of locking arms 33 and the sliding frame 331 for resetting, and the gravity arms 332 are pulled by the No. 1 springs 334 to resetting and move in the sliding frame 331;

[0096] The centrifugal locking unit also includes:

[0097] A plurality of wedge blocks 34 are equidistantly spaced on one side of the gravity arm 332 for locking the position of the locking tooth plate 333. The inclined surface of each wedge block 34 is arranged toward the locking tooth plate 333. A stopper 35 is fixedly installed on one side of the sliding frame 331. A pull rod 36 is slidably penetrated on the stopper 35. A limit block 37 is slidably installed on the sliding frame 331. A slide rail cooperating with the limit block 37 is arranged on the sliding frame 331. The limit block 37 is in contact with the vertical surface of the wedge block 34 to complete the one-way limit. To prevent the locking tooth plate 333 from resetting, a second spring 38 is sleeved on the outside of the pull rod 36, and the second spring 38 is located between the stop block 35 and the limit block 37. The second spring 38 pushes the limit block 37 to move and contact the wedge block 34. At the same time, the wedge block 34 can be installed on the other side of the gravity arm 332. It can be freely increased or decreased according to the actual locking state. At the same time, the elastic strength of the first spring 334 and the second spring 38 can be freely set according to the environment, thereby ensuring the stable locking work.

[0098] It is worth noting that: when performing centrifugal sensing protection: by providing a centrifugal locking unit, when the suspension rope 7 is damaged or broken, the weight of the counterweight hook 12, the electroplating rack and the products thereon are synchronously transferred to the protection rope 11, so that the winding shaft 9 rotates rapidly to generate centrifugal force. Since the gravity arm 332 adopts a counterweight design, it senses the centrifugal force brought by the winding shaft 9 and moves out in the sliding frame 331, so that the locking tooth plate 333 moves to contact the inner gear ring 32 to complete the bite locking. The design of multiple locking arms 33 makes the overall centrifugal locking work more It is stable and can quickly lock and protect the product. In order to improve the effect of centrifugal locking, a plurality of wedge blocks 34 are installed on one side of the gravity arm 332.
