Description

Technical Field

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

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is frequently used in workshops, factories, warehouses, and other places, and is widely used in the field of machinery. When a crane lifts and moves heavy objects, it needs to use crane lifting tools, among which the commonly used crane lifting tools are special rigging such as hooks, wire ropes, and chains.

[0003] Currently, common crane lifting devices often cause the load to sway during the lifting process after vertically lifting it. This makes it easy for the load to collide with other machines or objects, making it difficult to ensure the safety of the lifting process. Utility Model Content

[0004] Based on the problems mentioned in the background art above, this utility model provides an anti-sway lifting device to solve the problem that the load will swing during the movement of the load after it has been vertically lifted by the current common crane lifting devices.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An anti-sway lifting device includes:

[0007] The main frame has a rectangular array of vertical suspension point components at its top;

[0008] A sub-frame is installed directly below the main frame via a lifting component.

[0009] An inclined lifting point component, wherein multiple inclined lifting point components are provided and are respectively provided on both sides of the long side of the top of the sub-frame;

[0010] The hooks are provided in multiples and are respectively arranged in the middle of the bottom end of the sub-frame by an array of mounting seats;

[0011] The restraining components are provided in four parts, two of which are located on the front long side wall of the sub-frame and the other two are located on the rear long side wall of the sub-frame.

[0012] Based on the above technical solution, the present invention has made the following improvements:

[0013] Furthermore, the vertical lifting point component includes a vertical lifting base, and a pulley is provided on the vertical lifting base.

[0014] Furthermore, the lifting component includes a support one and a support two. The support one is located on the bottom side of the main frame, and the support two is located on the top of the sub-frame. A connecting block is hinged between the support one and the support two.

[0015] Furthermore, the inclined suspension point component includes an inclined suspension seat, which is located on the top long side of the sub-frame and tilts outward from the sub-frame. The inclined suspension seat is equipped with a pulley.

[0016] Furthermore, the resisting component includes an inclined plate, which is obliquely disposed on the long side wall of the sub-frame. A stop rod is screwed into the inclined plate, and an actuating frame is provided at the top of the stop rod.

[0017] The beneficial effects of this utility model are:

[0018] 1. By combining the main frame, multiple vertical lifting point components, sub-frame, and lifting connection components, and using multiple steel cables to connect each vertical lifting point component to the crane's lifting drum, a three-dimensional structure is formed. This effectively solves the problem of easy swaying when using single or double steel cables to lift the hook. The sub-frame is suspended directly below the main frame using lifting connection components, and the length and width of the sub-frame are greater than those of the main frame. This increases the stability of the hook at the bottom of the sub-frame and reduces the swing amplitude of the lifting device by changing the center of gravity.

[0019] 2. Through the setting of inclined lifting point components, during the hoisting process, the steel cables on the inclined lifting point components located on both sides of the long side of the sub-frame can play an inclined pulling role, which can further play a stabilizing role.

[0020] 3. Through the four resisting components, during the hoisting process, the resisting components located on the front long side wall of the sub-frame and the resisting components located on the rear long side wall of the sub-frame can respectively resist the upper sides of the hoisting shaft, thereby preventing the shaft from swinging during the hoisting process.

[0028] like Figures 1-4 As shown, an anti-sway lifting device includes:

[0029] The main frame 101 has a rectangular array at its top with multiple vertical lifting point components. Each vertical lifting point component includes a lifting base 102 and a pulley 103 on the lifting base 102. The pulley 103 can be connected to the steel cable on the lifting drum in the middle of the crane trolley, so that each vertical lifting point component is connected to the lifting drum in the middle of the crane trolley by multiple steel cables to form a three-dimensional structure. This can effectively solve the problem of easy swinging when using single or double steel cables to lift the hook 402.

[0030] The sub-frame 301 is set directly below the main frame 101 via a lifting component. The lifting component includes a first support 201 and a second support 203. The first support 201 is set on the bottom side of the main frame 101, and the second support 203 is set on the top of the sub-frame 301. A connecting block 202 is hinged between the first support 201 and the second support 203. The combination of the first support 201, the second support 203, and the connecting block 202 enables the main frame 101 and the sub-frame 301 to be connected and assembled together. The sub-frame 301 can be slightly adjusted left and right around the main frame 101 below the lifting component.

[0031] Multiple inclined lifting point components are provided and are respectively set on both sides of the top long side of the sub-frame 301. The inclined lifting point components include inclined lifting seats 302, which are set on the top long side of the sub-frame 301 and inclined outward of the sub-frame 301. The inclined lifting seats 302 are provided with pulleys 303, which can be connected to the steel cables on the auxiliary traction lifting drums at both ends of the crane trolley. This allows each inclined lifting point component to be connected to the auxiliary lifting drums at both ends of the crane trolley by multiple steel cables. Thus, during the lifting process, the steel cables on the inclined lifting point components located on both sides of the long side of the sub-frame 301 can play an inclined pulling role, which can further stabilize the sub-frame 301.

[0032] Multiple hooks 402 are provided and are arrayed at the bottom center of the sub-frame 301 via mounting bases 401. Each hook 402 can jointly lift a heavy object axle, so that the heavy object axle is lifted at the bottom center of the sub-frame 301. Since the sub-frame 301 can be slightly adjusted left and right around the lifting component below the main frame 101, the slight swing of the sub-frame 301 and the heavy object axle during the lifting process is transmitted to the main frame 101 and the steel cable of the lifting drum in the middle of the crane trolley.

[0033] The system includes four restraining components. Two of these components are located on the front long side wall of the sub-frame 301, and the other two are located on the rear long side wall. Each restraining component includes an inclined plate 501, which is positioned diagonally downwards on the long side wall of the sub-frame 301. A stop rod 502 is screwed into the inclined plate 501, and a lever 503 is located at the top of the stop rod 502. When the heavy axle is hoisted to the center of the bottom of the sub-frame 301, the corresponding stop rod 502 can be rotated and moved diagonally downwards by rotating each lever 503. This causes the stop rods 502 on the front and rear long side walls of the sub-frame 301 to resist the upper sides of the heavy axle, thereby further stabilizing the heavy axle hoisted below the sub-frame 301 and preventing the axle from swaying during hoisting.

[0034] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
