Description

Technical Field

[0001] This utility model relates to the field of crane lifting equipment technology, and specifically to a lifting equipment docking and guiding device. Background Technology

[0002] When using spreader for lifting, sometimes due to space limitations, it's inconvenient for the spreader to directly contact the cargo. In such cases, the hook needs to be released from the spreader to contact the cargo. To maintain a stable connection between the spreader and the hook and prevent unnecessary swaying, a support device, such as a support column, is installed between them to achieve a rigid connection. However, due to this rigid connection, during lifting and lowering, any speed change, such as a sudden start or stop, will generate significant impact force between the spreader and the hook. Furthermore, during the docking process, the rigid connection prevents the hook from flexibly adjusting its position. Unlike a flexible connection, the hook cannot adjust its position with slight swaying to dock with the cargo. Therefore, a flexible connection between the hook and the spreader is needed that maintains a stable connection and prevents easy swaying.

[0003] For example, patent application number 202420236438.9, published on February 28, 2025, discloses an anti-sway device for a battery swapping hoist, including a horizontally arranged support beam. The top of the support beam is provided with two symmetrically arranged movable pulley assemblies, which are assembled at both ends of the support beam. Below the support beam is a horizontally arranged upper hanger. Between the upper hanger and the support beam are four symmetrically arranged connecting rods. The top ends of the four connecting rods are hinged to the bottom end of the support beam, and the bottom ends of the connecting rods are respectively hinged to the four corners of the top of the upper hanger. Below the upper hanger is a horizontally arranged lower hanger. Between the lower hanger and the upper hanger are four connecting columns distributed in a spatial rectangle and with adjustable length. Several hooks are fixed at the bottom end of the lower hanger.

[0004] The above-mentioned documents describe a system where a hook is fixedly connected to the lower lifting frame, which is connected to the upper lifting frame via a column. Therefore, the lower and upper lifting frames are rigidly connected, and the hook is fixed to the lower frame, making its position difficult to adjust for docking with the cargo through slight swaying. Furthermore, the rigid connection of the lower lifting frame lacks buffering capacity against external disturbances. Since there is no flexible connection or buffering device between the lower and upper lifting frames, these swaying movements are directly transmitted to the cargo, potentially causing damage to the cargo or the lifting equipment structure. In actual lifting operations, if flexible steel wire ropes are used, even slight swaying of the crane or external factors such as wind can cause the cargo to sway, resulting in poor lifting performance. If a flexible steel wire rope is used to lift and guide the lifting device for docking, the excessive weight of the guide device will cause it to exert excessive impact on the lifting equipment during docking, potentially damaging the lifting equipment. Summary of the Invention

[0005] This utility model provides a lifting device for docking, which is easy to operate, prevents the hook from swinging relative to the lifting device, and reduces the impact of excessive force on the lifting device.

[0006] To achieve the above objectives, the technical solution of this utility model is: a lifting device for docking and guiding, comprising a lifting device, a winch device at the top of the lifting device for winding and unwinding a wire rope, conical portions along the four sides of the lifting device, the conical portions being fixedly connected to the lifting device, a rope loop at the tail end of the wire rope, the rope loop being connected to the conical body, the wire rope passing through a conical hole and connecting to the rope loop and the conical portion, the conical portion having a conical hole matching the conical body, the winch device winding and unwinding the wire rope causing the rope loop to move, causing the conical body to abut against the conical portion, and after the conical body abuts against the conical hole, there is a gap between the upper end of the conical body and the point where the conical hole connects to the lifting device.

[0007] The above configuration ensures that when the winch retracts or extends the wire rope, causing the rope loop to move, the cone body abuts against the cone section. Because the cone hole is a conical guide hole structure, the cone body entering the conical hole is guided, thus automatically achieving centering. Even if there is a certain deviation in the initial position, the cone body will automatically adjust its position along the inclined surface of the cone section, ultimately achieving precise centering. Because the lifting device and the rope loop are connected by a wire rope in a flexible manner, when the rope loop is carrying a heavy object, the cone is inserted into the conical part by the winch device, so that the cone fits tightly against the inner wall of the conical hole. As the wire rope is further tightened, the cone abuts against the conical hole, thus making the cone and the conical hole act as one unit. This gradually transforms the flexible connection into a rigid connection, reducing swaying and offset during the lifting process, making the lifting operation more stable and convenient. At the same time, because there is a gap at the connection between the cone and the conical hole and the lifting device, the cone cannot directly exert too much impact on the lifting device when it is connected, thus preventing damage to the lifting device. If the conical part is damaged, it can be replaced by replacing the conical part.

[0008] Furthermore, the top of the conical portion is provided with a first through hole, and the lifting device is provided with a second through hole. The first through hole and the second through hole are connected and their centers are located on the same axis.

[0009] With the above configuration, the first and second through holes are connected and their centers are on the same axis, ensuring that the wire rope can move in a straight line when passing through the first and second through holes, thus reducing the friction between the wire rope and the through hole wall.

[0010] Furthermore, the winch device includes a guide wheel located on one side of the second through hole, through which the wire rope passes.

[0011] In the above setup, the guide wheel's main function is to change the direction of the wire rope's movement, allowing the wire rope to pass through the first through hole from the second through hole.

[0012] Furthermore, the conical portion includes an abutment portion, and the cross-sectional area of ​​the inner wall of the conical hole gradually decreases from the abutment portion toward the first through hole.

[0013] With the above configuration, the cross-sectional area of ​​the conical part gradually decreases from the abutment portion towards the first through hole, forming a guiding slope. This slope guides the cone to smoothly enter the conical part, reducing positional deviation during docking and improving docking accuracy.

[0014] Furthermore, the cone includes a guide portion and a locking portion, the guide portion being located at the top of the cone, the locking portion being located below the guide portion, and the cross-sectional area of ​​the locking portion being larger than the cross-sectional area of ​​the abutment portion.

[0015] With the above configuration, the guide part is located at the top of the cone, which allows the cone to enter the cone more smoothly when it approaches the cone part, thereby reducing the positional deviation during docking and improving the docking accuracy. Since the cross-sectional area of ​​the locking part is larger than that of the abutting part, when the locking part on the cone abuts the abutting part on the cone part, the cone cannot move upwards anymore, and the rope loop will not loosen or wobble.

[0016] Furthermore, the cone is fixedly connected to the rope ring, and a third through hole is provided in the middle of the cone. The rope ring includes an extension part and a ring part, the extension part is connected to the ring part, and the third through hole is connected to the extension part.

[0017] The above configuration ensures a secure connection between the cone and the rope loop, preventing them from loosening or separating during hoisting. When the cone extends into the conical part, the conical part limits its movement. The cone connects to the extension part through the third through hole, further limiting the rope loop and reducing swaying and offset during hoisting, making the hoisting operation more stable.

[0018] Furthermore, the cone is made of nylon.

[0019] The cone is made of nylon, which has good impact resistance and wear resistance. It can not only reduce wear during frequent docking and separation, but also absorb and disperse impact during hoisting.

[0020] Furthermore, a baffle plate is provided on the wire rope in the gap. The middle part of the baffle plate is fixedly connected to the wire rope, and the two sides of the baffle plate abut against the inner wall of the conical hole. There is a gap between the baffle plate and the top of the cone.

[0021] The above setup, since the cone is made of nylon, includes a baffle plate at the top. When the nylon cone deforms under impact, the baffle plate can limit the large deformation force, preventing excessive deformation that could cause the cone to fail to return to its original state and resulting in poor docking guidance. At the same time, the baffle plate can further resist the excessive upward impact force of the rope ring on the cone, preventing the rope ring from breaking out of the cone.

Detailed Implementation

[0027] like Figure 1-4 As shown, a lifting device includes a lifting device 1, a winch device 2 on the top of the lifting device 1 for winding and unwinding a wire rope 22, and conical portions 3 along the four sides of the lifting device 1 connected to the lifting device 1. A rope loop 5 is provided at the tail end of the wire rope 22 and is connected to a cone 4. The conical portions 3 and the cone 4 are matched and matched. The winch device 2 winds and unwinds the wire rope 22, causing the rope loop 5 to move, so that the cone 4 and the conical portion 3 abut against each other.

[0028] The top of the conical part 3 is provided with a first through hole 31, and the lifting device 1 is provided with a second through hole 11. The first through hole 31 and the second through hole 11 are connected and their centers are located on the same axis. The connection between the first through hole 31 and the second through hole 11 and their centers are located on the same axis ensures that the wire rope 22 can move in a straight line when passing through the two through holes, reducing the friction between the wire rope 22 and the through hole wall.

[0029] The winch device 2 includes a guide wheel 21, which is located on one side of the second through hole 11. The guide wheel 21 allows the wire rope 22 to pass through. The main function of the guide wheel 21 is to change the direction of movement of the wire rope 22, so that the wire rope 22 can pass through the first through hole 31 from the second through hole 11.

[0030] The conical portion 3 includes an abutment portion 32. The cross-sectional area of ​​the conical portion 3 gradually decreases from the abutment portion 32 toward the first through hole 31, forming a guiding slope. This slope can guide the cone 4 to smoothly enter the conical portion 3, reducing positional deviation during docking and improving docking accuracy.

[0031] The cone 4 includes a guide portion 41 and a locking portion 43. The guide portion 41 is located at the top of the cone 4, and the locking portion 43 is located below the guide portion 41. The cross-sectional area of ​​the locking portion 43 is larger than the cross-sectional area of ​​the inner wall of the abutment portion 32. The guide portion 41 is located at the top of the cone 4, which allows the cone 4 to enter the cone 3 more smoothly when it approaches the cone 3, thereby reducing the positional deviation during docking and improving the docking accuracy. Since the cross-sectional area of ​​the locking portion 43 is larger than the cross-sectional area of ​​the inner wall of the abutment portion 32, when the locking portion 43 on the cone 4 abuts against the abutment portion 32 on the cone 3, the cone 4 cannot move upward anymore, and the rope ring 5 will not loosen or shake.

[0032] The cone 4 is fixedly connected to the rope ring 5. A third through hole 42 is provided in the middle of the cone 4. The rope ring 5 includes an extension part 52 and a ring part 51. The extension part 52 is connected to the ring part 51. In one embodiment, the third through hole 42 and the extension part 52 are integrally provided. In another embodiment, the third through hole 42 and the extension part 52 are separately provided. The bottom of the extension part 52 is fixedly connected to the ring part 51. Then, the cone 4 and the rope ring 5 are fixedly connected by the interference fit between the extension part 52 and the third through hole 42. The fixed connection between the cone 4 and the rope ring 5 ensures a firm connection between the two, so that the cone 4 and the rope ring 5 will not loosen or separate during the hoisting process. When the cone 4 extends into the cone part 3, the cone part 3 limits the cone 4. The cone 4 abuts against the extension part 52 through the third through hole 42 to limit the rope ring 5, reducing the swaying and displacement during the hoisting process and making the hoisting operation more stable.

[0033] like Figure 3 As shown, a baffle plate 44 is provided on the wire rope 22 in the gap. The middle part of the baffle plate 44 is fixedly connected to the wire rope 22. The two sides of the baffle plate 44 abut against the inner wall of the conical hole. There is a gap between the lower side of the baffle plate 44 and the top surface of the cone 4.

[0034] The working principle of this invention is as follows: When the winch device 2 retracts or extends the wire rope 22, causing the rope loop 5 to move, the cone 4 and the cone portion 3 come into contact. Due to the characteristics of the cone shape, an automatic centering effect is achieved. Even if there is a certain deviation in the initial position, the cone 4 will automatically adjust its position along the inclined surface of the cone portion 3, ultimately achieving precise centering. Because the lifting device 1 and the rope loop 5 are connected flexibly by the wire rope 22, when the rope loop 5 is carrying a heavy object, and the winch device 2 extends the cone 4 into the cone part 3, the cone 4 fits tightly against the cone part 3. Furthermore, the cone 4 is made of nylon, which has good impact resistance and wear resistance, reducing wear during frequent docking and disengagement, and absorbing and dispersing impact forces during lifting. As the wire rope 22 is further tightened, the flexible connection gradually transforms into a rigid connection, reducing swaying and offset during lifting and making the lifting operation more stable.
