Description

Technical Field

[0001] This invention belongs to the field of hot-dip galvanizing lifting equipment, and particularly relates to an automatic lifting device for hot-dip galvanizing pickling. Background Technology

[0002] Currently, hot-dip galvanizing involves immersing pickled and rust-removed steel components in molten zinc, causing a zinc layer to adhere to the surface of the steel components, thus achieving corrosion protection. Hot-dip galvanizing is an effective method of metal corrosion protection; during the pickling process, steel components need to be placed into the pickling tank using lifting equipment.

[0003] For example, the patent document with publication number CN113682991A discloses an automatic lifting device for hot-dip galvanizing and pickling. The device uses a controller to start the first drive motor and the second drive motor, which in turn drive the rotating rod to rotate and automatically rewind the steel wire to achieve the lifting.

[0004] For example, patent document CN214114632U discloses a hot-dip galvanizing lifting fixture, including a lifting fixture, a sliding groove, a positioning arm, and a cylinder. The lifting fixture has a lifting frame at the top center, and lifting holes at both ends of the lifting frame. The lifting fixture has sliding grooves at both ends of the front side, and a top groove at the top of the sliding groove. A mounting hole is provided on one side of the sliding groove, and a positioning bushing is fixedly installed in the mounting hole. A slider is provided in the sliding groove, and the slider and the positioning arm are an integral structure. A cylinder is connected to the positioning bushing on the corresponding side of the slider. A tapered positioning shaft is provided on the inner side near the bottom end of the positioning arm, and a ceramic sealing sleeve is fitted on the tapered positioning shaft.

[0005] For example, patent document CN210944515U discloses a lifting tool for hot-dip galvanizing steel components of power transmission towers, which includes two supports. A horizontal beam is fixed between the tops of the two supports. The beam has an "I" shape. An electric hoist is slidably mounted on the beam. The pulley of the electric hoist is embedded in the recesses on the left and right sides of the "I" shaped beam. A connecting rod is longitudinally fixed on the hook of the electric hoist.

[0006] The lifting device provided by the above solution for hot-dip galvanizing uses a single rope structure and lacks safety protection. It uses the winding of the rope to lift the hot-dip galvanizing components. When the lifting device lifts the components into the air, it cannot provide support and protection if the rope structure or other lifting structures fail, which makes the hot-dip galvanizing operation dangerous. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic lifting device for hot-dip galvanizing pickling, which aims to solve the problem that existing hot-dip galvanizing lifting devices cannot provide buffer protection when the lifting structure fails.

[0008] To achieve the above objectives, the present invention provides the following technical solution.

[0009] An automatic lifting device for hot-dip galvanizing pickling, the automatic lifting device comprising:

[0010] A support column is provided, the position of which is adjusted along a fixed track by a displacement component;

[0011] The lifting device is supported on the lifting beam, which is fixedly installed on the top of the lifting column. The lifting column includes a lifting plate, which is telescopically mounted on the supporting cylinder.

[0012] The protective support mechanism includes a fixing part, which includes multiple sets of first support groups and multiple sets of second support groups; the multiple sets of first support groups and multiple sets of second support groups are alternately fixed in sequence along the vertical direction in the inner cavity of the support cylinder; the protective support mechanism also includes a moving part, which includes a rotating disk base, and two protective support rods are fixedly installed on the outer ring of the rotating disk base, and the two protective support rods are symmetrically fixed on the rotating disk base.

[0013] In one embodiment of the present invention, the supporting cylinder is fixedly installed on a movable base; wherein, the displacement component includes a first forward and reverse motor fixedly installed on the movable base, and a displacement gear is installed on the output shaft of the first forward and reverse motor;

[0014] The displacement component also includes a track tooth surface disposed on the fixed track, the track tooth surface meshing with the displacement gear;

[0015] The fixed track has a track groove that slides along the movable base.

[0016] In one embodiment of the present invention, the first support group is located below the second support group; wherein, the first support group includes a first support plate A and a first support plate B, and the second support group includes a second support plate A and a second support plate B;

[0017] Along the axial direction of the support cylinder, the projections of the first support plate A, the second support plate A, the first support plate B, and the second support plate B on the cross-section of the support cylinder sequentially enclose an annular surface, and the annular surface is coaxial with the axis of the support cylinder.

[0018] The first support plate A and the first support plate B are symmetrically arranged on the inner wall of the support cylinder. Two first arc-shaped regions are formed between the two ends of the first support plate A and the two ends of the first support plate B. The second support plate A and the second support plate B are symmetrically arranged on the inner wall of the support cylinder, and the second support plate A and the second support plate B are respectively located directly above the two first arc-shaped regions of the first support group.

[0019] The second support plate A and the second support plate B are symmetrically arranged on the inner wall of the support cylinder. Two second arc-shaped regions are formed between the two ends of the second support plate A and the two ends of the second support plate B. The first support plate A and the first support plate B are symmetrically arranged on the inner wall of the support cylinder, and the first support plate A and the first support plate B are respectively located directly below the two second arc-shaped regions of the second support group.

[0020] There is a buffer area between the first support group and the second support group.

[0021] In one embodiment of the present invention, the protective support mechanism further includes a fixed upright, which is coaxially fixedly installed inside the support cylinder, and a fixed toothed surface is provided on one side of the fixed upright in a vertical direction.

[0022] In one embodiment of the present invention, the movable part further includes a support plate base, the rotating plate base is rotatably disposed on the support plate base, and the support plate base is fixedly installed at the bottom end of the lifting column; a linkage gear meshing with the fixed tooth surface is rotatably disposed on the support plate base; a drive bevel gear is also rotatably disposed on the support plate base; a third forward and reverse motor is also fixedly disposed on the support plate base, the third forward and reverse motor is a dual-shaft extension motor, one output shaft of the third forward and reverse motor is drivenly connected to the linkage gear, and the other output shaft of the third forward and reverse motor is drivenly connected to the drive bevel gear.

[0023] A driven bevel gear that meshes with the driving bevel gear is coaxially fixedly mounted on the rotating disk base;

[0024] A first support plate is also fixedly installed on the support plate, and a first support shaft is rotatably supported on the first support plate. The linkage gear is coaxially and fixedly installed on the first support shaft.

[0025] In one embodiment of the present invention, a drive gear is mounted on another output shaft of the third forward and reverse motor, and a second support plate is fixedly mounted on the support plate. The drive bevel gear is rotatably mounted on the second support plate. A driven gear is coaxially connected to the drive bevel gear, and the driven gear meshes with the drive gear.

[0026] When the drive gear is rotated by the third forward and reverse motor, the drive bevel gear rotates under the meshing and linkage of the driven gear.

[0027] In one embodiment of the present invention, when the movable part is located within the enclosed area of ​​the first support plate A and the first support plate B, the protective support rod is located within the first arc-shaped area; when the movable part is located within the buffer area, the protective support rod is also located within the buffer area; when the movable part is located within the enclosed area of ​​the second support plate A and the second support plate B, the protective support rod is located within the second arc-shaped area.

[0028] In one embodiment of the present invention, the lifting device includes a fixed support plate fixedly installed on the lifting beam, an adjusting screw is rotatably provided on the fixed support plate, and the lifting device further includes a second forward and reverse motor for driving the adjusting screw to rotate, the second forward and reverse motor being installed on the fixed support plate;

[0029] The lifting device also includes two sets of hangers, which are respectively installed on two horizontal sliding plates. The two horizontal sliding plates are respectively set at both ends of the adjusting screw by means of threaded connection, wherein the external threads at both ends of the adjusting screw have opposite directions.

[0030] In one embodiment of the present invention, the hanging component includes a hanging frame, the top end of which is rotatably mounted on the transverse sliding plate via a rotating coupling; the hanging component also includes a hook, which is fixedly mounted on the hanging frame via a connecting support plate.

[0031] An anti-slip plate is slidably fitted on the hook. Multiple limiting grooves are evenly distributed on the anti-slip plate. A limiting component that cooperates with the limiting groove is installed on the hanger. By adjusting the position of the anti-slip plate relative to the hook, the opening of the hook can be closed by the anti-slip plate, so as to prevent the component from slipping off the hook when the component is hoisted by the hook.

[0032] In one embodiment of the present invention, the limiting component includes a limiting cylinder fixedly installed on the hanger, a rectangular slider is slidably provided on the limiting cylinder by a supporting spring, and a limiting ridge block that cooperates with the limiting groove is fixedly installed on the rectangular slider, with the inclined surface of the limiting ridge block facing the opening of the hook.

[0033] Compared with the prior art, the lifting device provided by the present invention utilizes the third forward and reverse motor to drive the linkage gear to rotate. Because the linkage gear meshes with the fixed tooth surface, the moving part can move upward relative to the fixed upright. When the lifting plate moves vertically relative to the supporting cylinder, the other output shaft of the third forward and reverse motor also drives the drive bevel gear to rotate synchronously. Because the drive bevel gear meshes with the driven bevel gear, when the lifting plate moves vertically relative to the supporting cylinder, it also drives the rotating disk to rotate relative to the supporting disk.

[0034] During the upward movement of the lifting column, the moving part moves upward within the support cylinder. As the moving part moves upward, the rotating base rotates relative to the support base. The protective support rod on the rotating base continuously performs circular motion as the moving part moves upward. Due to the arc-shaped area, the upward movement of the moving part does not affect the movement of the protective support rod within the arc-shaped area and does not cause interference. Due to the buffer area, the moving part transitions from the enclosed area of ​​the first support group to the enclosed area of ​​the second support group through the buffer area. This allows the protective support rod to move from the enclosed area of ​​the first support group to the enclosed area of ​​the second support group without interfering with either the first or second support group.

[0035] In summary, this invention achieves the upward lifting of the moving part by starting the third forward and reverse motor, while simultaneously causing the protective support rod to move. As the power supply for moving the lifting column upward, when the meshing between the linkage gear and the fixed tooth surface fails, the falling moving part will cause the protective support rod to directly land on either the second or first support group, thus providing support and protection for the falling moving part. This ensures that the moving part only falls a short distance before being supported and protected by the first or second support group, avoiding the danger of falling directly to the bottom.

[0036] In a specific implementation of the lifting device provided by the present invention, the hot-dip galvanized component is gripped by adjusting the relative positions of the two sets of hangers. In a specific implementation of the hanger provided by the present invention, the anti-detachment plate is pushed to slide relative to the hook, thereby closing the opening of the hook. During the process of closing the opening, the end of the anti-detachment plate abuts against the inclined surface of the limiting block, pushing the limiting block into the limiting cylinder until the limiting block abuts against the corresponding limiting groove, thus locking the anti-detachment plate relative to the hook and preventing the component from slipping off the hanger, ensuring safety and reliability.

Detailed Implementation

[0048] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0049] Example 1

[0050] like Figure 1 As shown, in one embodiment of the present invention, an automatic lifting device for hot-dip galvanizing pickling is provided, the automatic lifting device comprising:

[0051] A support cylinder 100 is provided, and its position along a fixed track 200 is adjusted by a displacement component. The support cylinder 100 is fixedly mounted on a movable base 101. The displacement component includes a first forward / reverse motor 102 fixedly mounted on the movable base 101. A displacement gear 103 is mounted on the output shaft of the first forward / reverse motor 102. The displacement component also includes a track tooth surface 202 disposed on the fixed track 200, which meshes with the displacement gear 103. The first forward / reverse motor 102 is a bidirectional rotary motor, which can drive the displacement gear 103 to rotate in both directions. When the first forward / reverse motor 102 drives the displacement gear 103 to rotate, the position of the movable base 101 on the fixed track 200 is adjusted according to the rotation direction of the displacement gear 103 driven by the first forward / reverse motor 102, that is, the position of the support cylinder 100 along the fixed track 200 is adjusted.

[0052] Furthermore, in this embodiment of the invention, the fixed track 200 is provided with a track groove 201 that slides with the movable base 101, and the movable base 101 slides along the track groove 201.

[0053] Please continue reading. Figure 1 In this embodiment of the invention, the automatic lifting device further includes a lifting device 400, which is supported on the lifting beam 300. The lifting beam 300 is fixedly installed on the top of the lifting column 700. The lifting column 700 includes a lifting plate 701, which is telescopically mounted on the supporting cylinder 100.

[0054] The present invention uses a lifting device 400 to grab the component, and then adjusts the height of the lifting column 700 relative to the supporting column 100, and further adjusts the position of the supporting column 100 along the fixed track 200, so that the lifting device 400 carrying the component is adjusted above the pickling tank, and then the component is placed into the pickling tank for processing.

[0055] Please continue reading. Figure 5 - Figure 9 In this embodiment of the invention, the automatic lifting device further includes a protective support mechanism, which includes a fixing part, and the fixing part includes multiple sets of first support groups 104 and multiple sets of second support groups 105; the multiple sets of first support groups 104 and multiple sets of second support groups 105 are alternately fixed in sequence along the vertical direction in the inner cavity of the support cylinder 100.

[0056] For example, in an embodiment of the present invention, there may be a second support group 105 between two adjacent first support groups 104.

[0057] Taking the first support group 104 and the second support group 105 of adjacent groups as an example, in this embodiment of the invention, the first support group 104 is located below the second support group 105; wherein, the first support group 104 includes a first support plate A1041 and a first support plate B1042, and the second support group 105 includes a second support plate A1051 and a second support plate B1052.

[0058] Furthermore, such as Figure 6 As shown, in this embodiment of the invention, along the axial direction of the support cylinder 100, the projections of the first support plate A1041, the second support plate A1051, the first support plate B1042, and the second support plate B1052 on the cross-section of the support cylinder 100 sequentially enclose an annular surface, and the annular surface is coaxially arranged with the axis of the support cylinder 100.

[0059] Specifically, the first support plate A1041 and the first support plate B1042 are symmetrically arranged on the inner wall of the support cylinder 100, and two first arc-shaped regions are formed between the two ends of the first support plate A1041 and the two ends of the first support plate B1042. The second support plate A1051 and the second support plate B1052 are symmetrically arranged on the inner wall of the support cylinder 100, and the second support plate A1051 and the second support plate B1052 are respectively located directly above the two first arc-shaped regions of the first support group 104.

[0060] Correspondingly, the second support plate A1051 and the second support plate B1052 are symmetrically arranged on the inner wall of the support cylinder 100. Two second arc-shaped regions are formed between the two ends of the second support plate A1051 and the two ends of the second support plate B1052. The first support plate A1041 and the first support plate B1042 are symmetrically arranged on the inner wall of the support cylinder 100, and the first support plate A1041 and the first support plate B1042 are respectively located directly below the two second arc-shaped regions of the second support group 105.

[0061] Furthermore, in this embodiment of the invention, there is a buffer area between the first support group 104 and the second support group 105, that is, the second support group 105 is located above the first support group 104, and there is a distance between the first support group 104 and the second support group 105.

[0062] Please continue reading. Figure 5 - Figure 9In this embodiment of the invention, the protective support mechanism further includes a movable part, which includes a rotating disk seat 800. Two protective support rods 801 are fixedly installed on the outer ring of the rotating disk seat 800, and the two protective support rods 801 are symmetrically fixed on the rotating disk seat 800.

[0063] Furthermore, in this embodiment of the invention, the protective support mechanism further includes a fixed upright 900, which is coaxially fixedly installed inside the support cylinder 100, and a fixed tooth surface 901 is provided on one side of the fixed upright 900 in a vertical direction.

[0064] Furthermore, in this embodiment of the invention, the moving part further includes a support plate 702, the rotating plate 800 is rotatably disposed on the support plate 702, and the support plate 702 is fixedly installed at the bottom end of the lifting column 700; a linkage gear 704 that meshes with the fixed tooth surface 901 is rotatably disposed on the support plate 702; a drive bevel gear 708 is also rotatably disposed on the support plate 702; a third forward and reverse motor 600 is also fixedly mounted on the support plate 702, the third forward and reverse motor 600 is a dual-shaft extension motor, one output shaft of the third forward and reverse motor 600 is drivenly connected to the linkage gear 704, and the other output shaft of the third forward and reverse motor 600 is drivenly connected to the drive bevel gear 708.

[0065] Furthermore, in this embodiment of the invention, a driven bevel gear 802 that meshes with the driving bevel gear 708 is coaxially fixedly mounted on the rotating disk base 800.

[0066] Furthermore, such as Figure 8 As shown, in this embodiment of the invention, a first support plate 703 is also fixedly provided on the support plate 702, and a first support shaft 705 is rotatably supported on the first support plate 703. The linkage gear 704 is coaxially fixedly installed on the first support shaft 705.

[0067] Furthermore, in this embodiment of the invention, a drive gear 706 is mounted on another output shaft of the third forward and reverse motor 600, and a second support plate 709 is fixedly mounted on the support plate 702. The drive bevel gear 708 is rotatably mounted on the second support plate 709. A driven gear 707 is coaxially connected to the drive bevel gear 708, and the driven gear 707 meshes with the drive gear 706.

[0068] Therefore, when the third forward and reverse motor 600 rotates the drive gear 706, the driven bevel gear 708 can be rotated under the meshing and linkage of the driven gear 707.

[0069] Therefore, it can be understood that in the embodiments of the present invention, during the process of driving the linkage gear 704 to rotate by the third forward and reverse motor 600, since the linkage gear 704 meshes with the fixed tooth surface 901, the moving part can move upward relative to the fixed upright 900. When the lifting plate 701 moves vertically relative to the supporting cylinder 100, the other output shaft of the third forward and reverse motor 600 also drives the driving bevel gear 708 to rotate synchronously. Since the driving bevel gear 708 meshes with the driven bevel gear 802, when the lifting plate 701 moves vertically relative to the supporting cylinder 100, it also drives the rotating disk 800 to rotate relative to the supporting disk 702.

[0070] Furthermore, in this embodiment of the invention, when the movable part is located within the area enclosed by the first support plate A1041 and the first support plate B1042, the protective support rod 801 is located within the first arc-shaped area; when the movable part is located within the buffer area, the protective support rod 801 is also located within the buffer area; when the movable part is located within the area enclosed by the second support plate A1051 and the second support plate B1052, the protective support rod 801 is located within the second arc-shaped area.

[0071] In other words, during the upward movement of the lifting column 700, the moving part moves upward within the support cylinder 100. During this upward movement, the rotating disk 800 rotates relative to the support disk 702. The protective support rod 801 on the rotating disk 800 continuously performs circular motion as the moving part moves upward. Due to the arc-shaped area, the upward movement of the moving part does not affect the movement of the protective support rod 801 within the arc-shaped area without interference. Due to the buffer area, the moving part transitions from the enclosed area of ​​the first support group 104 to the enclosed area of ​​the second support group 105 through the buffer area. This allows the protective support rod 801 to move from the enclosed area of ​​the first support group 104 to the enclosed area of ​​the second support group 105 without interfering with either the first or second support group 104.

[0072] Therefore, the present invention enables the protective support rod 801 to move simultaneously during the upward lifting of the moving part by activating the third forward and reverse motor 600. As the power supply for moving the lifting column 700 upward, when the meshing between the linkage gear 704 and the fixed tooth surface 901 fails, the falling moving part will cause the protective support rod 801 to fall directly onto one of the second support groups 105 or the first support group 104, thus providing support and protection for the falling moving part. This ensures that the moving part only falls a short distance before being supported and protected by the first support group 104 or the second support group 105, avoiding the danger of falling directly to the bottom.

[0073] Example 2

[0074] like Figure 1 - Figure 2 As shown, unlike Embodiment 1, in this embodiment of the invention, the lifting device 400 includes a fixed support plate 401 fixedly installed on the lifting beam 300, an adjusting screw 402 rotatably mounted on the fixed support plate 401, and the lifting device 400 also includes a second forward and reverse motor 405 for driving the adjusting screw 402 to rotate, the second forward and reverse motor 405 being mounted on the fixed support plate 401.

[0075] Furthermore, in this embodiment of the invention, the lifting device 400 also includes two sets of hanging parts 500, which are respectively installed on two transverse plates 403. The two transverse plates 403 are respectively set at both ends of the adjusting screw 402 by threaded connection, and the external threads at both ends of the adjusting screw 402 have opposite directions.

[0076] Please continue reading. Figure 1 - Figure 2 In this embodiment of the invention, the top of the transverse plate 403 is also supported by a rotatable support roller 404, which is slidably mounted on the upper surface of the lifting beam 300.

[0077] In a specific implementation of the lifting device 400 provided by the present invention, the second forward and reverse motor 405 drives the adjusting screw 402 to rotate, and then adjusts the relative position between the two transverse plates 403 according to the rotation direction of the adjusting screw 402, thereby adjusting the distance between the two sets of hangers 500. Therefore, the relative position of the two sets of hangers 500 can be adjusted according to the volume of the hot-dip galvanized component to grip the hot-dip galvanized component.

[0078] like Figure 2 - Figure 4 As shown, in this embodiment of the invention, the hanging component 500 includes a hanging frame 501, the top end of which is rotatably mounted on the transverse plate 403 via a rotating connecting shaft 502; the hanging component 500 also includes a hook 503, which is fixedly mounted on the hanging frame 501 via a connecting support plate 506.

[0079] Furthermore, in this embodiment of the invention, an anti-slip plate 504 is slidably sleeved on the hook 503. A plurality of limiting grooves 5041 are evenly distributed on the anti-slip plate 504. A limiting component that cooperates with the limiting grooves 5041 is installed on the hanger 501. By adjusting the position of the anti-slip plate 504 relative to the hook 503, the opening of the hook 503 can be closed by the anti-slip plate 504, so as to prevent the component from slipping off the hook 503 when the component is hoisted by the hook 503.

[0080] Furthermore, such as Figure 3 - Figure 4 As shown, in this embodiment of the invention, the limiting component includes a limiting cylinder 505 fixedly installed on the hanger 501. A rectangular slider 5052 is slidably mounted on the limiting cylinder 505 by a supporting spring 5053. A limiting prism 5051 that cooperates with the limiting groove 5041 is fixedly installed on the rectangular slider 5052. The inclined surface of the limiting prism 5051 faces the opening of the hook 503.

[0081] Furthermore, in this embodiment of the invention, the hook 503 is provided with a T-shaped groove 5031, and the anti-detachment plate 504 is equipped with a T-shaped slider that cooperates with the T-shaped groove 5031. It can be understood that in the specific implementation of the hanging member 500 provided in this embodiment of the invention, by pushing the anti-detachment plate 504 to slide relative to the hook 503, the anti-detachment plate 504 closes the opening of the hook 503. During the process of closing the opening, the end of the forward end of the anti-detachment plate 504 abuts against the inclined surface of the limiting block 5051, pushing the limiting block 5051 to retract into the limiting cylinder 505 until the limiting block 5051 abuts against the corresponding limiting groove 5041, thereby completing the locking of the anti-detachment plate 504 relative to the hook 503. This is safe and reliable, and prevents the component from slipping off the hanging member 500.
