Description

Technical Field

[0001] The present application relates to the field of lifting equipment, and in particular to a lifting device. Background Art

[0002] The galvanizing process is a surface treatment technology that improves the corrosion resistance of steel and extends its service life by coating the surface of the steel with a layer of zinc. This process not only improves the physical properties of the steel, but also effectively isolates the steel from external corrosive media, thereby preventing the steel from rusting and corrosion.

[0003] Before galvanizing the steel section, a pickling process is required. It is often necessary to use a lifting device to immerse the steel section in a pickling tank to clean the rust and oxide layer on the surface of the steel section. The lifting process is to fix the steel section through a lifting belt, and then the lifting machine equipment uses the lifting belt to lift batches of steel pipe processing parts into the pickling tank for pickling treatment.

[0004] However, the lifting belt will cause a large number of stacking areas between batches of steel sections. After the stacking areas of the steel sections enter the pickling tank, it is difficult for the pickling liquid to fully contact with the steel sections, thereby affecting the pickling effect of the steel sections. Summary of the invention

[0005] In order to improve the pickling effect of steel sections during the pickling process, the present application provides a lifting device.

[0006] The present application provides a lifting device that adopts the following technical solution: A lifting device comprises two parallel beams, a connecting beam is arranged between the two beams, a U-shaped support frame is arranged below the beams, waist-shaped holes are opened at both ends of the support frame, and a partition component for layering steel sections is arranged between the waist-shaped holes.

[0007] By adopting the above technical solution, a layer of steel sections is laid on the support frame, and then a partition assembly is set on the steel sections, and then the steel sections are laid on the partition assembly, and this process is repeated again and again, so that the steel sections on the support frame are laid in layers. After the crossbeam is lifted and the support frame is transported to the pickling tank, the steel sections are not stacked, so that the steel sections are fully in contact with the pickling liquid, thereby improving the pickling effect of the steel sections.

[0008] Optionally, the partition assembly includes a plurality of partition rods distributed along the length direction of the waist-shaped hole, the partition rods are slidably inserted in the waist-shaped hole, both ends of the partition rods are threadedly connected with fixing blocks, and the fixing blocks are abutted against the support frame.

[0009] By adopting the above technical solution, when the steel section is laid on the support frame, the dividing rod slides along the waist-shaped hole until the steel section is pressed on the support frame, and then the steel section is laid on the dividing rod, thereby realizing the separation of the steel section. In addition, the fixing block is twisted and pressed against the support frame so that the dividing rod can be fixed on the support frame, thereby fixing the steel section on the support frame. When the support frame moves and shakes, the steel section can remain stable on the support frame.

[0010] Optionally, a hook is hinged on the crossbeam, and an S-shaped connecting piece is provided between the hook and the support frame. The connecting piece is hooked on the waist-shaped hole and the hook of the support frame at the same time. The support frame is also provided with a reinforcement component for reinforcing the partition rod.

[0011] By adopting the above technical solution, the connecting piece is used to connect the support frame and the hook, so that the support frame can swing slightly relative to the crossbeam, thereby facilitating the steel section to shake off waste chips during pickling, and quickly draining the moisture on the steel section after pickling, so that the steel section can quickly complete the pickling and enter the next process, thereby improving work efficiency. The reinforced components make it difficult for the partition rod and the steel section to move relative to the support frame, while reducing the swing amplitude of the support frame relative to the crossbeam, thereby improving the overall stability.

[0012] Optionally, the reinforcement assembly includes a reinforcement rod slidably inserted on the cross beam and facing the partition rod, and a driving sleeve mounted on the reinforcement rod is rotatably connected inside the cross beam. The driving sleeve is threadedly connected to the reinforcement rod, and a gear ring is provided on the outer wall of the driving sleeve. The end of all the hooks away from the connecting piece is abutted against the driving rod, the driving rod is slidably connected to the inside of the cross beam, and the driving rod is provided with a rack meshing with the gear ring.

[0013] By adopting the above technical solution, when the hook is hooked on the support frame, the hook rotates, squeezing and driving the driving rod to slide at the same time, the driving rod drives the gear ring to rotate through the rack, and the gear ring drives the reinforcement rod to slide through the thread until the reinforcement rod applies pressure to the partition rod, thereby improving the stability of the partition rod. In addition, during the rotation of the gear ring, the two racks maintain synchronous movement, so that the support frame can maintain smooth lifting and lowering, thereby improving the stability of the support frame and the steel section.

[0014] Optionally, a reinforcement cap is slidably connected to one end of the reinforcement rod close to the partition rod, and a buffer spring is provided between the reinforcement cap and the reinforcement rod.

[0015] By adopting the above technical solution, the height position of the dividing rod changes with the different types of steel sections. The buffer spring presses the reinforcement cap onto the topmost dividing rod. By utilizing the contraction characteristics of the buffer spring, the reinforcement rod can apply pressure to the dividing rod through the reinforcement cap, thereby meeting the pickling reinforcement requirements of steel sections of different specifications.

[0016] Optionally, a hoisting assembly is provided above the connecting beam, and vibration motors are provided above both ends of the cross beam.

[0017] By adopting the above technical solution, the hoisting assembly lifts and moves the crossbeam and the connecting beam, and the vibration motor vibrates the crossbeam when the support frame is suspended in the air, so that the support frame under the crossbeam vibrates, thereby the steel sections on the support frame can quickly shake off waste chips or moisture.

[0018] Optionally, the lifting assembly includes a lifting frame arranged above the connecting beam, the lifting frame is rotatably connected to two parallel rotating rods, the two rotating rods are provided with mutually meshing gears, the lifting frame is also equipped with a driving motor for driving the rotating rods to rotate, the rotating rods are all wrapped with steel cables, the ends of the steel cables away from the rotating rods are installed on the corresponding cross beams, and the lifting frame is also provided with an adjustment assembly for adjusting the relative height of the two cross beams.

[0019] By adopting the above technical solution, the driving motor drives the rotating rod to rotate, and the two rotating rods simultaneously gather or release the steel cables, thereby controlling the lifting and lowering of the beam and the support frame. When the support frame leaves the pickling tank, the adjusting component drives the two beams to have a height difference, thereby quickly tilting and pouring out the moisture on the support frame and the steel section.

[0020] Optionally, the adjustment assembly includes an adjustment rod parallel to the rotating rod, the adjustment rod is slidably connected to the hanging frame, and the adjustment rod and the rotating rod are located on both sides of the steel cable. A spindle is rotatably connected to the adjustment rod, and the steel cable abuts against the spindle. The hanging frame is also provided with a hydraulic cylinder for driving the adjustment rod to slide.

[0021] By adopting the above technical solution, the hydraulic cylinder drives the adjusting rod to move toward the side where the rotating rod is located. The adjusting rod abuts and squeezes the steel cable through the spindle, so that the steel cable is bent, thereby lifting the beam on the side. As a result, there is a height difference between the two beams, so that the water can be drained quickly.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: Steel sections are laid on the upper and lower sides of the partition assembly so that the steel sections on the support frame are not stacked, thereby allowing the steel sections to fully contact with the pickling liquid, thereby improving the pickling effect of the steel sections; The hoisting assembly lifts and moves the cross beam and the connecting beam, and the vibration motor vibrates the cross beam when the support frame is suspended in the air, so that the support frame under the cross beam vibrates, so that the steel on the support frame can quickly shake off the waste or moisture; The motor drives the rotating rod to rotate, and the two rotating rods simultaneously gather or release the steel cables, thereby controlling the lifting and lowering of the beam and the support frame. When the support frame leaves the pickling tank, the adjustment component drives the two beams to have a height difference, thereby quickly tilting and pouring out the moisture on the support frame and the steel section.

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] The present application embodiment discloses a lifting device. Figure 1 A hoisting device includes two parallel beams 1, a connecting beam 2 is fixedly connected between the two beams 1, a hoisting assembly 3 is arranged above the beams 1, and a U-shaped support frame 4 is arranged below the beams 1. Both ends of the support frame 4 are provided with waist-shaped holes 41, and a partition assembly 5 for layering steel sections is arranged between the waist-shaped holes 41.

[0029] Multiple layers of steel sections are laid on the support frame 4, and a group of partition components 5 are set between the upper and lower adjacent layers of steel sections, so that there is a gap between the two adjacent layers of steel sections on the support frame 4. After the crossbeam 1 and the support frame 4 are transported to the pickling tank by the hoisting component 3, the steel sections between the upper and lower layers are not stacked, thereby facilitating the pickling liquid to fully contact the steel sections through the gap and quickly completing the pickling work.

[0030] The partition assembly 5 includes a plurality of partition rods 51 distributed along the length direction of the waist-shaped hole 41. The partition rods 51 are slidably inserted in the waist-shaped hole 41. Both ends of the partition rods 51 are threadedly connected with fixing blocks 52, and the fixing blocks 52 abut against the support frame 4. When a layer of steel is laid on the support frame 4, the partition rods 51 slide along the waist-shaped hole 41 until the steel is pressed on the support frame 4, and then another layer of steel is laid on the partition rods 51, thereby realizing the separation of the steel. In addition, the fixing blocks 52 are twisted and pressed against the support frame 4, so that the partition rods 51 can be fixed on the support frame 4, thereby fixing the steel on the support frame 4, and when the support frame 4 moves and shakes, the steel can remain stable on the support frame 4.

[0031] Reference Figure 1 and Figure 2 A hook 11 is hinged on the crossbeam 1, and a torsion spring is provided between the hook 11 and the crossbeam 1 to connect the two. An S-shaped connecting piece 12 is provided between the hook 11 and the support frame 4. One end of the connecting piece 12 is hooked on the hook 11, and the other end is hooked on the support frame 4 at the same time. The support frame 4 is also provided with a reinforcement component 6 for reinforcing the partition rod 51.

[0032] The connecting piece 12 is used to connect the support frame 4 and the hook 11, so that the hook 11 can adapt to support frames 4 of different widths. In addition, the support frame 4 can be slightly swayed relative to the beam 1, so as to facilitate the steel section to throw off waste chips during pickling, and to quickly drain the moisture on the steel section after pickling, so that the steel section can quickly complete the pickling and enter the next process. The reinforcement component 6 makes it difficult for the partition rod 51 and the steel section to move relative to the support frame 4, while reducing the swing amplitude of the support frame 4 relative to the beam 1, thereby improving the overall stability.

[0033] The reinforcement assembly 6 includes a reinforcement rod 61 which is slidably inserted on the cross beam 1 and faces the partition rod 51. A driving sleeve 62 which is sleeved on the reinforcement rod 61 is rotatably connected inside the cross beam 1. The driving sleeve 62 is threadedly connected to the reinforcement rod 61. A coaxial gear ring 63 is fixedly connected to the outer wall of the driving sleeve 62. The ends of all hooks 11 away from the connecting piece 12 are abutted against a driving rod 64. The end face of the driving rod 64 abutting against the hook 11 is set as an inclined surface. The driving rod 64 is slidably connected inside the cross beam 1. A return spring connecting the driving rod 64 and the cross beam 1 is provided between the two. A rack 65 meshing with the gear ring 63 is fixed on the driving rod 64.

[0034] When the hook 11 hooks the support frame 4, the hook 11 rotates, squeezing and driving the driving rod 64 to slide at the same time. The driving rod 64 drives the ring gear 63 to rotate through the rack 65. The ring gear 63 drives the reinforcement rod 61 to slide through the thread until the reinforcement rod 61 applies pressure to the partition rod 51, thereby improving the stability of the partition rod 51. In addition, during the rotation of the ring gear 63, the two racks 65 maintain synchronous movement, so that the support frame 4 can maintain smooth lifting and lowering, thereby improving the stability of the support frame 4 and the steel section.

[0035] One end of the reinforcement rod 61 close to the partition rod 51 is slidably connected with a reinforcement cap 66, and a buffer spring 67 is installed between the reinforcement cap 66 and the reinforcement rod 61. Different materials are placed on the support frame 4, so the height position of the partition rod 51 also changes accordingly. The buffer spring 67 presses the reinforcement cap 66 against the partition rod 51 on the uppermost layer. By utilizing the contraction characteristic of the buffer spring 67, the reinforcement rod 61 can apply pressure to the partition rod 51 through the reinforcement cap 66, thereby reinforcing the partition rod 51 within a certain height range.

[0036] Reference Figure 1 and Figure 3 The hoisting assembly 3 is arranged above the connecting beam 2, and a vibration motor is arranged above both ends of the beam 1, which is not shown in the figure. The hoisting assembly 3 lifts and moves the beam 1 and the connecting beam 2, and the vibration motor vibrates the beam 1 when the support frame 4 is suspended in the air, so that the support frame 4 under the beam 1 vibrates, so that the steel on the support frame 4 can quickly throw off the waste or moisture.

[0037] The hoisting assembly 3 includes a hoisting frame 31 arranged above the connecting beam 2, and two parallel rotating rods 32 are rotatably connected to the hoisting frame 31. Coaxially arranged gears 33 are fixed on the two rotating rods 32, and the two gears 33 are meshed with each other. A driving motor for driving the rotating rods 32 to rotate is also installed on the hoisting frame 31. Steel cables 34 are wound around the rotating rods 32, and the ends of the steel cables 34 away from the rotating rods 32 are installed on the corresponding beams 1. The hoisting frame 31 is also provided with an adjustment component for adjusting the relative height of the two beams 1.

[0038] The driving motor drives the rotating rod 32 to rotate, and the two rotating rods 32 simultaneously gather or release the steel cable 34, thereby controlling the lifting and lowering of the beam 1 and the support frame 4. When the support frame 4 leaves the pickling tank, the adjustment component drives the two beams 1 to have a height difference, thereby quickly tilting and pouring out the water on the support frame 4 and the steel section.

[0039] The adjusting assembly includes an adjusting rod 35 parallel to the rotating rod 32. The adjusting rod 35 is slidably connected to the hanging frame 31, and the adjusting rod 35 and the rotating rod 32 are located on both sides of the steel cable 34. A spindle 36 is rotatably connected to the adjusting rod 35, and the steel cable 34 abuts against the spindle 36. The hanging frame 31 is also provided with a hydraulic cylinder 37 for driving the adjusting rod 35 to slide.

[0040] The hydraulic cylinder 37 drives the adjusting rod 35 to move toward the side where the rotating rod 32 is located. The adjusting rod 35 abuts against and squeezes the steel cable 34 through the spindle 36, so that the steel cable 34 is bent, thereby lifting the beam 1 on the side where it is located. As a result, there is a height difference between the two beams 1, so that the water can be drained quickly.

[0041] The implementation principle of a lifting device in an embodiment of the present application is as follows: the steel section is placed on the support frame 4, and the steel sections of two adjacent layers are separated by a partition rod 51, and then the connecting piece 12 is hooked on the support frame 4 and the hook 11 at the same time, and the driving motor drives the rotating rod 32 to rotate, the steel cable 34 is wound, and the beam 1 rises and moves above the pickling tank, and then the rotating rod 32 rotates in the opposite direction, and the steel cable 34 is pulled down, so that the steel section on the support frame 4 enters the pickling tank. After the pickling is completed, the steel section is lifted again and leaves the pickling tank, and then the hydraulic cylinder 37 drives the spindle 36 to squeeze the steel cable 34 on one side, so that the steel section tilts, and then the water is quickly drained.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
