Description

Technical Field

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

[0002] In the mold manufacturing process, cranes are typically used to lift and transport the molds. However, due to the high toughness of the hooks and slings, the molds, being heavy, often exhibit significant inertia during movement and stopping, preventing them from accurately reaching their designated positions and resulting in considerable swaying. If adjustments are not made promptly, this not only affects work efficiency but may also cause injury to nearby personnel and property, leading to loss of life and property and posing a significant safety hazard. Utility Model Content

[0003] In view of this, the present invention provides an anti-sway structure for lifting equipment. The anti-sway structure set on the lifting equipment can fix and limit the movement of the lifted object, prevent it from swinging, greatly reduce damage to nearby personnel and objects, and make the operation safer and more convenient.

[0004] To solve the above-mentioned technical problems, this utility model provides an anti-sway structure for lifting devices. The anti-sway structure is installed on the lifting frame of the lifting device and includes an adjustment component on the lifting frame. An anti-sway rod is installed on the adjustment component, which is used to adjust the position and height of the anti-sway rod. A limiting cylinder adapted to the anti-sway rod is installed on the upper part of the object to be lifted. This utility model allows the anti-sway rod to be adjusted to coincide with the axis of the limiting cylinder through the adjustment component, and then the anti-sway rod is inserted into the limiting cylinder. This works in conjunction with the lifting device to achieve anti-sway operation for the object to be lifted. This solves the problem that in traditional crane auxiliary lifting devices for lifting and transporting molds, due to the high toughness of the hook and sling, the mold's own weight often results in significant inertia during movement and stopping, often preventing accurate positioning and resulting in considerable swaying. If adjustments are not made in time, it will not only affect work efficiency, but may also cause harm to nearby people and objects, resulting in loss of life and property and posing a significant safety hazard. This greatly improves the stability of objects during lifting operations, making the operation safer and more convenient.

[0005] The adjustment assembly includes a slide cylinder mounted on the lifting frame, a slide rod inserted inside the slide cylinder, and a sleeve at the lower part of the slide rod. An anti-sway rod is slidably mounted inside the sleeve. This invention allows for adjustment of the position of the anti-sway rod through the cooperation of the slide rod and the slide cylinder, facilitating guidance and limiting operations for different positions of different objects being lifted. Simultaneously, the anti-sway rod slidably mounted inside the sleeve allows for limiting the distance between the lifting frame and the object to be lifted at different heights, making operation more convenient.

[0006] Both the sleeve and the limiting cylinder have internal threads on their inner sides, and the upper and lower parts of the anti-sway rod are provided with external threads that are compatible with the internal threads. This utility model can greatly increase the detachable connection between the anti-sway rod and the limiting cylinder through the cooperation between the external threads on the anti-sway rod and the internal threads in the sleeve and the limiting cylinder, which greatly increases the portability of the anti-sway rod in installation and disassembly, and makes operation more convenient.

[0007] The slide cylinder has a positioning groove inside, and the slide rod is equipped with a positioning strip that matches the positioning groove. This utility model can achieve the positioning operation of the slide rod by the cooperation of the positioning strip and the positioning groove, which makes it easy for the operator to quickly and efficiently insert the positioning strip into the slide cylinder.

[0008] The slide cylinder has threaded holes with through-positioning grooves. The threaded holes are connected to hand-tightening bolts. There are two threaded holes, which are symmetrically arranged at both ends of the slide cylinder, and there are also two corresponding hand-tightening bolts.

[0009] A handle is provided on the outer side wall of the anti-sway bar, and a rubber anti-slip sleeve is provided on the handle.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. This utility model can adjust the position of the anti-sway bar by adjusting the cooperation between the sliding rod and the sliding cylinder in the adjustment component, which facilitates the guidance and limiting of different positions of different objects to be lifted, and avoids excessive swinging during the lifting operation, which poses a great safety hazard.

[0012] 2. This utility model can fix and lock the position of the slide rod after it has been adjusted by tightening the hand-tightening bolt, which greatly increases the stability of the anti-sway structure.

[0013] 3. This utility model can achieve the positioning operation of the slide bar by cooperating with the positioning strip and the positioning groove, which makes it convenient for the operator to quickly and efficiently insert the positioning strip into the slide cylinder.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] like Figure 1-3 As shown: This embodiment provides an anti-sway structure for a lifting device. The anti-sway structure is installed on the lifting frame 100 of the lifting device and includes an adjustment component 200 installed on the lifting frame 100. An anti-sway rod 300 is installed on the adjustment component 200. The adjustment component 200 is used to adjust the position and height of the anti-sway rod 300. A limiting cylinder adapted to the anti-sway rod 300 is installed on the upper part of the object to be lifted. This utility model can adjust the anti-sway rod 300 to coincide with the axis of the limiting cylinder through the adjustment component 200, and then insert the anti-sway rod 300 into the limiting cylinder. This can be used with the lifting device to achieve anti-sway operation of the object to be lifted. This solves the problem that in the lifting and conveying operation of molds by traditional crane auxiliary lifting devices, due to the high toughness of the hook and sling, the mold itself is heavy and has a large inertia during movement and stopping, often failing to reach the corresponding position accurately and always having a considerable degree of sway. If adjustments are not made in time, it will not only affect work efficiency, but may also cause harm to nearby people and objects, resulting in loss of life and property and posing a significant safety hazard. This greatly improves the stability of objects during lifting operations, making the operation safer and more convenient.

[0020] According to one embodiment of the present invention, such as Figure 1-3As shown, the adjustment assembly 200 includes a slide cylinder 201 mounted on the hanger 100, a slide rod 202 inserted inside the slide cylinder 201, and a sleeve 203 located at the lower part of the slide rod 202. An anti-sway rod 300 is slidably mounted inside the sleeve 203. This invention allows for adjustment of the position of the anti-sway rod 300 through the cooperation of the slide rod 202 and the slide cylinder 201, facilitating guidance and limiting operations for different positions of different lifted objects. Simultaneously, the anti-sway rod 300 slidably mounted inside the sleeve 203 allows for limiting the position of the hanger 100 of the lifting device at different heights from the object to be lifted, making operation more convenient.

[0021] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, both the sleeve 203 and the limiting cylinder have internal threads on their inner sides, and the upper and lower parts of the anti-sway rod 300 are provided with external threads that are compatible with the internal threads. This utility model can greatly increase the detachable connection between the anti-sway rod 300 and the limiting cylinder through the cooperation between the external threads on the anti-sway rod 300 and the internal threads in the sleeve 203 and the limiting cylinder, which greatly increases the portability of the anti-sway rod 300 for installation and disassembly, and makes operation more convenient.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, a positioning groove is provided inside the slide cylinder 201, and a positioning strip that matches the positioning groove is provided on the slide rod 202. This utility model can achieve the positioning operation of the slide rod 202 by the cooperation of the positioning strip and the positioning groove, which makes it convenient for the operator to quickly and efficiently insert the positioning strip into the slide cylinder 201.

[0023] The slide cylinder 201 has a threaded hole with a through positioning groove, and a hand-tightening bolt 204 is threadedly connected to the threaded hole. This utility model can fix and lock the position of the slide rod 202 after it has been adjusted by tightening the hand-tightening bolt 204, which greatly increases the stability of the anti-sway structure.

[0024] A handle 400 is provided on the outer side wall of the anti-sway bar 300. This utility model allows the anti-sway bar 300 to be detachably connected to the sleeve 203 by the operator holding the handle 400 and rotating it, which greatly increases the stability of the lifting operation of the anti-sway bar 300, the sleeve 203, and the object to be lifted under the sleeve 203.

[0025] How to use this utility model:

[0026] First, it needs to be clarified that the anti-sway structure involved in this utility model is mainly used to prevent the lifting equipment from swaying during the lifting and moving of the object to be lifted by a crane or overhead crane in conjunction with a nylon wire rope. This utility model takes the use of the anti-sway structure in the lifting process of a mold body as an example to describe its usage in detail. When it is necessary to lift the mold body, the operator first hooks one end of the nylon wire rope onto the lifting equipment, and the other end hooks onto the lifting ring of the mold body. Then, the operator loosens the hand-tightening bolt 204 and pulls the sliding rod 202 along the sliding cylinder 20. 1. Slide the anti-sway bar 300 until its axis coincides with the axis of the sleeve 203 on the upper part of the mold body. Then, the operator holds the handle 400 and rotates the anti-sway bar 300 until its lower threaded connection enters the sleeve 203. Then, the crane or overhead crane can be started to move the lifting device and the mold body lifted below it in a convenient and quick manner. This utility model can fix and limit the lifting object during the movement by setting an anti-sway structure on the lifting device, avoiding its swing and greatly eliminating damage to nearby personnel and objects, making the operation safer and more convenient.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
