Abstract
Description
Technical Field
[0001] The utility model relates to the field of cranes, in particular to a crane hoisting rope anti-sway device. Background Art
[0002] Cranes play a vital role in industrial production and construction, used for lifting and moving heavy objects. Using hooks, wire ropes, and other devices, cranes lift heavy objects from the ground or a specific location into the air and move them to a designated location under the operator's control. Cranes operate based on the principles of leverage and mechanics, using motors and hydraulic systems to achieve both lifting and translational movement. However, when a crane lifts and moves a heavy object, it can swing due to inertia. In such situations, operators who are not proficient in crane control are forced to wait for the object to slowly come to a stop. This swinging of the lifted object not only affects operational efficiency but can also pose a safety hazard to the operator and the surrounding environment. Utility Model Content

The anti-sway stabilization device includes a winch, a rope is wound inside the winch, and the rope is used to connect to the hoisted heavy object. The winch is installed on a base, and the base is movably installed on the column and can be moved up and down and fixed.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-Figure 3 As shown, a crane hoisting rope anti-sway device includes a pair of columns 1, a crossbeam 2 is erected on the top of the column 1, a lifting device 3 is installed on the crossbeam 2, and an anti-sway stabilization device 4 is installed on the column body of the column 1. The two anti-sway stabilization devices 4 are installed symmetrically and can be adjusted in height on the column 1, so as to facilitate matching the lifting height of different weights and make it easier and more labor-saving for the winch 7 to pull the heavy objects.
[0022] like Figure 4-Figure 5 As shown, the anti-sway stabilization device 4 includes a hoist 7 with a rope 8 wound inside. The back of the hoist 7 has pre-set mounting screw holes and is bolted to a cross-mounting plate 9. The cross-mounting plate 9 has three rows of screw holes on its surface: the top and bottom rows are for mounting the hoist 7, and the middle row is used to bolt the cross-mounting plate 9 to a base 10. The outer surface of the base 10 has a corresponding row of screw holes. A lock is fixed to the end of the rope 8 for quickly connecting to the hook below the lifting device 3.
[0023] like Figure 4-Figure 5 As shown, the winch 7 is mounted on a base 10, the column 1 is an H-shaped steel structure, and the base 10 is a C-shaped integrated structure. A clamping block 16 is fixedly mounted on the inner wall of each side. The clamping block 16 is fixed to the base 10 by an outer hexagon socket bolt 17, and forms a concave connecting groove 14 with the two side walls of the base 10. The shape of the connecting groove 14 matches the H-shaped cross-section of the column 1, so that the base 10 is sleeved on the column 1. A protrusion is provided on the inner surface of the base 10, which extends into the H-shaped groove of the column 1, and two rows of auxiliary wheels 15 are movably mounted on the surface of the protrusion, and the auxiliary wheels 15 are closely attached to the inner wall of the H-shaped groove of the column 1.
[0024] In this embodiment, a pair of limiting screw holes 13 are further provided on the protruding portion of the inner surface of the base 10, and several pairs of limiting fixing holes 5 are vertically provided on the inner wall of the H-shaped groove of the column 1. After the limiting screw holes 13 on the base 10 correspond to the limiting fixing holes 5, a pair of limiting pins 6 are used to fix the base 10 to the column 1. The limiting pin 6 consists of a screw 11 at the head and a ring 12 at the tail. The screw 11 forms a threaded connection with the limiting screw hole 13, and the ring 12 is directly welded to the screw 11. The design of the ring 12 makes it convenient to insert and tighten the limiting pin 6 directly by hand, and the ring 12 can also be tightened and reinforced by rotating it with a stick-like object.
[0025] In actual use, to install the anti-sway stabilization device 4, first unscrew the hexagon socket bolts 17 on the base 10 and remove the two clamping blocks 16. Then, align the base 10 with one side of the column 1 and insert it. Then, install the two clamping blocks 16 on the other side of the base 10, forming a snap-fit structure to fit the base 10 onto the column 1. Then, align the limiting screw holes 13 on the base 10 with the limiting fixing holes 5 on the column 1, and screw the two limiting pins 6 through the limiting fixing holes 5 and into the limiting screw holes 13 to secure the base 10. Then, bolt the cross mounting plate 9 to the surface of the base 10, and then bolt the winch 7 to the cross mounting plate 9. At this point, the entire anti-sway stabilization device 4 is assembled and installed.
[0026] When a crane lifts a heavy object off the ground and begins to hoist it, the object inevitably swings due to inertia. Therefore, before the lifting device 3 moves horizontally, the rope 8 in the winch 7 on the side of the moving direction is first connected to the hook or the heavy object, and then the winch 7 is started. The winding tension of the winch 7 is used to slightly move the heavy object in the moving direction. By first slightly moving the heavy object along the moving direction of the lifting device 3, several key effects can be achieved to reduce swing: First, this provides the heavy object with an initial velocity so that its inertia force is consistent with the moving direction of the lifting device 3. Therefore, when the lifting device 3 begins to move, the inertia of the heavy object will not conflict with the moving direction of the lifting device 3, offsetting the swing that may be caused by sudden acceleration or deceleration. Second, this method reduces the change in acceleration because the heavy object does not start to move suddenly from a stationary state, but gradually accelerates. This makes the change in acceleration more gradual, reducing the swing caused by sudden acceleration changes. Finally, moving the weight first helps achieve dynamic synchronization between the weight and the lifting device 3, ensuring that the speed and movement of the two are more coordinated and consistent, avoiding swinging caused by speed mismatch.
[0027] It should be noted that since the winch 7 only slightly moves the weight in the moving direction, that is, as long as a pulling force is applied to the weight in the horizontal direction, the anti-sway stabilizing device 4 should be installed at a position substantially at the same height as the weight. In view of the different lifting heights of weights of different sizes, the limit fixing hole 5 is provided on the column 1 to facilitate the height adjustment of the anti-sway stabilizing device 4. It is only necessary to unscrew the limit pin 6, then push or pull the base 10 up and down to the appropriate position and then install the limit pin 6. The auxiliary wheel 15 installed on the protruding part of the base 10 is to facilitate up and down movement.
[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
