Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an anti-sway crane. Background Technology

[0002] A crane is an engineering device used to lift heavy objects. It is widely used in construction engineering and port lighting, which greatly reduces manpower and material resources and improves work efficiency. When using a crane, it is usually necessary to use anti-sway devices to prevent the lifted objects from swaying.

[0003] For example, a lifting equipment anti-sway device with announcement number "CN212315299U" is equipped with a support frame. When an item is lifted, the rope passes around the bottom of a fixed pulley, and the ropes on both sides of the fixed pulley are symmetrically distributed relative to the center line of the pulley. Under the action of the item's weight, the ropes are stretched. Guide sleeves are fitted on the ropes on both sides of the fixed pulley. At this time, the ropes, guide sleeves, support rods, and fixing plates form a support structure that is symmetrical about the axis of rotation, which can maintain the stability of the support frame. The sliding rods on both sides of the bottom of the support frame play a role in fixing the item, reducing swaying and improving the stability of the item. However, in this lifting equipment anti-sway device, after the hook lifts the item, it fixes the item through multiple sliding rods. Since the angle of the sliding rods cannot be adjusted, when the lifted item is small, the sliding rods cannot fix it, thus increasing the limitations of the operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem that after a hook lifts an item, multiple sliding rods are used to fix the item, but the angle of the sliding rods cannot be adjusted. When the lifted item is small, the sliding rods cannot fix it, which increases the limitation of the operation. Therefore, an anti-sway crane is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an anti-sway crane, comprising a movable plate and ropes. Multiple ropes are fixedly connected to the upper part of the movable plate, and multiple first fixed seats are fixedly connected to the movable plate. Each first fixed seat is movably connected to a sleeve via a pin. Each sleeve is provided with an adjustment mechanism on its inner side. A hook is fixedly connected to the lower end of the movable plate. The inner wall of the sleeve is slidably connected to a locking block and a vertical rod, respectively. Multiple first threaded holes are machined on the vertical rod, and second threaded holes are machined on the sleeve.

[0007] Preferably, both the second threaded hole and the first threaded hole are threadedly connected to the bolt, and a pressure block is movably connected to the bottom of each vertical rod via a pin.

[0008] Preferably, the adjusting mechanism includes round rods and a second fixed seat. Both sides of the multiple round rods are machined with external threads, and the external threads are all threaded to internal threads. The internal threads are respectively machined on the first connecting rod and the second connecting rod. The outer wall of the first connecting rod is movably connected to the second fixed seat through a pin. The outer wall of the second fixed seat is fixedly connected to the cylinder. The outer wall of the second connecting rod is movably connected to the third fixed seat through a pin.

[0009] Preferably, the external threads machined on both sides of the round rod have opposite directions of rotation.

[0010] Preferably, the outer wall of the third fixed seat is fixedly connected to the movable plate.

[0011] The anti-sway crane proposed in this utility model has the following advantages: through the cooperation of the first fixed seat, the sleeve and the adjustment mechanism, the operator rotates the round rod in the forward direction. The rotation of the round rod drives the first connecting rod and the second connecting rod to move inward synchronously, thereby driving the sleeve to swing along the connection point with the first fixed seat. This, in turn, drives the vertical rod and the pressure block to move, so that the angle of the vertical rod can be adjusted as needed. It can fix items of different sizes, thereby reducing the limitations of the work. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6 In this embodiment, an anti-sway crane includes a movable plate 1 and ropes 2. Multiple ropes 2 are fixedly connected to the upper part of the movable plate 1. The ropes 2 and hooks 4 are the main structure of the crane. Multiple first fixed seats 12 are fixedly connected to the movable plate 1. Each first fixed seat 12 is movably connected to a sleeve 7 through a pin. Each sleeve 7 is provided with an adjustment mechanism 3 on its inner side. A hook 4 is fixedly connected to the lower end of the movable plate 1. The inner wall of the sleeve 7 is slidably connected to a locking block 5 and a vertical rod 9 respectively. Multiple first threaded holes 6 are machined on the vertical rod 9, and second threaded holes 11 are machined on the sleeve 7.

[0021] Both the second threaded hole 11 and the first threaded hole 6 are threadedly connected to the bolt 8. The vertical rod 9 is movably connected to the pressure block 10 through the pin. The external threads 304 machined on both sides of the round rod 301 have opposite directions of rotation. The outer wall of the third fixed seat 306 is fixedly connected to the moving plate 1.

[0022] The adjusting mechanism 3 includes a round rod 301 and a second fixed seat. Both sides of the multiple round rods 301 are machined with external threads 304, and the external threads 304 are threaded to internal threads 305. The internal threads 305 are respectively machined on the first connecting rod 302 and the second connecting rod 303. The outer wall of the first connecting rod 302 is movably connected to the second fixed seat 307 through a pin. The outer wall of the second fixed seat 307 is fixedly connected to the cylinder 7. The outer wall of the second connecting rod 303 is movably connected to the third fixed seat 306 through a pin.

[0023] Working principle:

[0024] When using anti-sway cranes:

[0025] The operator controls the crane to move the lifting rope 2 and the moving plate 1, which in turn moves the hook 4. When the hook 4 can lift the item, the crane is turned off.

[0026] The operator hangs the hook 4 on the item. The operator first adjusts the tilt angle of the vertical rod 9 according to the size of the item. The operator rotates the round rod 301 forward. The rotation of the round rod 301 drives the first connecting rod 302 and the second connecting rod 303 to move inward in sync. This causes the sleeve 7 to swing along the connection point with the first fixed seat 12, which in turn causes the vertical rod 9 and the pressure block 10 to move. This allows the angle of the vertical rod 9 to be adjusted as needed, and items of different sizes can be fixed, thereby reducing the limitations of the work.

[0027] When the vertical rod 9 and the pressure block 10 are moved to a position where they can secure the item, stop rotating the round rod 301. Then, the operator adjusts the height of the vertical rod 9 according to the height of the item. The operator pulls the vertical rod 9 downwards, thereby moving the vertical rod 9 and the locking block 5 downwards along the inner wall of the sleeve 7, which in turn moves the pressure block 10 downwards. When the bottom of the pressure block 10 is in contact with the item, the first threaded hole 6 and the second threaded hole 11 are aligned. Then, the operator rotates the bolt 8 so that the end of the bolt 8 is screwed into the second threaded hole 11 and the first threaded hole 6 respectively, thereby securing the pressure plate 10. The position is fixed by the pressure plate 10 and the hook 4. Then, the operator controls the movement of the rope 2 through the crane to lift the item. When the item is lifted, the pressure plate 10 and the hook 4 can increase the stability of the item and prevent it from swaying. Then, by controlling the crane, the item can be moved to the designated position. When the item is moved to the designated position, the operator turns multiple bolts 8 so that the bolts 8 are unscrewed from the first threaded hole 6 and the second threaded hole 11 respectively. Then, the vertical rod 9 is returned to its initial position. Finally, the item is removed from the hook 4.
