Description

Technical Field

[0001] This utility model relates to the field of hoisting structure technology, specifically to a large steel component hoisting anti-sway stabilization mechanism. Background Technology

[0002] Steel components refer to components or parts made primarily of steel through processing techniques such as cutting, welding, bolting, rolling, and forging, used in engineering fields such as construction, machinery, bridges, and ships. They are characterized by high strength, light weight, good seismic performance, and short construction periods, making them an indispensable core component of modern engineering structures. Due to the large size of steel components, hoisting equipment is used for transportation at heights.

[0003] Currently, when hoisting strip steel components, the two ends of the steel component are usually fixed, and then the component is lifted by hooking the ropes that are tied to it. This hoisting method is relatively simple, but it is prone to swaying and tilting during hoisting. In this case, the steel component is prone to falling, which makes its stability poor during hoisting. Utility Model Content

[0004] The purpose of this invention is to provide a stabilizing mechanism for hoisting large steel components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large steel component hoisting anti-sway stabilization mechanism, comprising: a connecting seat for docking with a crane; a docking block rotatably disposed at the lower end of the connecting seat; two balance chains rotatably disposed at the lower end of the docking block; a balance bar rotatably disposed at the lower ends of the two balance chains, the balance chains being inclined; hooks fixedly disposed at the bottom end of the balance bar, the hooks being symmetrically disposed on the balance bar, the two hooks being located near the two ends of the balance bar respectively; a steel component body disposed on the hooks; a pressure sleeve fixedly disposed at the bottom end of the balance bar and located at the center position; a pressure screw slidably disposed inside the pressure sleeve; an adjusting sleeve rotatably disposed on the pressure sleeve, the adjusting sleeve having a threaded connection between its interior and the outer surface of the pressure screw; and a contact block rotatably disposed at the bottom end of the pressure screw, the inner surface of the contact block being in contact with the outer surface of the steel component body.

[0006] Preferably, it further includes: two buffer ropes, fixedly installed on both sides of the connecting seat; a damper, fixedly installed at the other end of the buffer ropes, the other end of the damper being installed on the steel component body; the buffer ropes and the damper are arranged at an angle.

[0007] Preferably, it further includes: two No. 1 binding straps, fixedly installed on the steel component body, with the No. 1 binding straps fixedly installed between the hooks; and two No. 2 binding straps, fixedly installed on the steel component body near both ends, with one end of the damper fixedly installed to the surface of the No. 2 binding straps.

[0008] Preferably, it further includes: a positioning strip, fixedly disposed on the inner surface of the pressure sleeve; and a positioning groove, formed on the surface of the pressure screw, wherein the outer surface of the positioning strip is slidably disposed with respect to the inside of the positioning groove.

[0009] Preferably, it further includes: a limiting groove formed on the outer surface of the pressing sleeve; and a limiting ring fixedly disposed inside the adjusting sleeve, wherein the outer surface of the limiting ring is rotatably disposed from the inside of the limiting groove.

[0010] Preferably, it further includes: a safety chain, fixedly installed at the bottom end of the docking block and located at the center position, the other end of the safety chain being fixedly installed at the top of the balance bar, and the safety chain being perpendicular to the balance bar.

[0011] Preferably, the contact block has a C-shaped cross-section.

[0012] This utility model provides a sway-proof and stabilizing mechanism for hoisting large steel components, which has the following beneficial effects:

[0013] (1) By rotating the adjusting sleeve, the adjusting sleeve pushes the pressing screw to move downward during the rotation process. During the movement of the pressing screw, the contact block is brought into contact with the steel component body and pressed, so that the hook between the steel component body and the balance bar is in a taut state. Through the cooperation of the balance chain, balance bar and hook, the steel component body is more likely to achieve balance during the lifting process, which improves the stability of the steel component body during the lifting process.

[0014] (2) By setting up buffer ropes and dampers, this utility model can reduce the swaying amplitude of the steel component body during the swaying process, making it easier for the steel component body to restore balance and improving the stability of hoisting. Attached Figure Description

Steel component body. Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: Referring to 1-4, in this embodiment, a large steel component hoisting anti-sway stabilizing mechanism includes: a connecting seat 1 for docking with a crane; a docking block 2 rotatably disposed at the lower end of the connecting seat 1; two balance chains 3 rotatably disposed at the lower end of the docking block 2; a balance bar 4 rotatably disposed at the lower end of the two balance chains 3, the balance chains 3 being inclined; hooks 13 fixedly disposed at the bottom end of the balance bar 4, the hooks 13 being symmetrically disposed on the balance bar 4, the two hooks 13 being located near the two ends of the balance bar 4 respectively; a steel component body 19 disposed on the hooks 13; a pressure sleeve 5 fixedly disposed at the bottom end of the balance bar 4 and located at the center position; a pressure screw 6 slidably disposed inside the pressure sleeve 5; and an adjusting sleeve 8 rotatably disposed... The adjusting sleeve 8 is threaded onto the outer surface of the pressing screw 6 and placed on the pressing sleeve 5. The contact block 7 is rotatably mounted on the bottom end of the pressing screw 6, and its inner surface is in contact with the outer surface of the steel component body 19. The balance chain 3 disperses the force on the connecting block 2, improving balance. The balance bar 4 increases the fixing area with the steel component body 19 by cooperating with the hook 13, making the lifting process more balanced and less prone to shaking. The pressing screw 6, pressing sleeve 5, and contact block 7 apply pressure to the steel component body 19, ensuring that the steel component body 19 and the balance bar 4 are in a taut state, preventing large-scale shaking of the steel component body 19 during lifting and improving stability.

[0022] It also includes: two buffer ropes 16, fixedly installed on both sides of the connecting seat 1; a damper 17, fixedly installed at the other end of the buffer ropes 16, and the other end of the damper 17 is installed on the steel component body 19; the buffer ropes 16 and the damper 17 are inclined, which can apply tension to both ends of the steel component body 19 to ensure balance, and when the steel component sways, the damper 17 can reduce the sway amplitude of the steel component body 19, making it easier to reach a balanced state again, thus improving the stability during the hoisting process.

[0023] It also includes: two No. 1 binding straps 14, which are fixedly installed on the steel component body 19, and the No. 1 binding straps 14 are fixedly installed between the hooks 13; two No. 2 binding straps 18, which are fixedly installed on the steel component body 19 near both ends, and one end of the damper 17 is fixedly installed on the surface of the No. 2 binding straps 18, so as to facilitate the installation and fixing of the steel component body 19.

[0024] It also includes: a positioning strip 9, which is fixedly set on the inner surface of the pressing sleeve 5; and a positioning groove 10, which is opened on the surface of the pressing screw 6. The outer surface of the positioning strip 9 and the inside of the positioning groove 10 are slidably set to limit the pressing screw 6, thereby preventing the pressing screw 6 from rotating.

[0025] It also includes: a limiting groove 11, which is formed on the outer surface of the pressing sleeve 5; and a limiting ring 12, which is fixedly set inside the adjusting sleeve 8. The outer surface of the limiting ring 12 is rotatably set inside the limiting groove 11, which can limit the adjusting sleeve 8 so that it can rotate during the connection with the pressing sleeve 5.

[0026] It also includes: a safety chain 15, which is fixedly installed at the bottom of the docking block 2 and located at the center position. The other end of the safety chain 15 is fixedly installed at the top of the balance bar 4. The safety chain 15 is set perpendicular to the balance bar 4 and can perform auxiliary tensioning to reduce the direct force on the balance chain 3, so that it can lift the heavier steel component body 19.

[0027] The contact block 7 has a C-shaped cross-section, which makes it easier to press and limit the steel component body 19.

[0028] This utility model provides a sway-prevention and stabilization mechanism for hoisting large steel components. The specific working principle is as follows:

[0029] The workers placed the steel component body 19 directly below the balance bar 4, then attached the first binding strap 14 and the second binding strap 18, and tightened them after adjusting the position. Next, the workers hooked the hook 13 onto the first binding strap 14 and rotated the adjusting sleeve 8. As the adjusting sleeve 8 rotated, it pushed the pressure screw 6 downwards. During the movement of the pressure screw 6, the contact block 7 came into contact with the steel component body 19 and applied pressure, ensuring that the hook 13 between the steel component body 19 and the balance bar 4 was taut. Finally, the workers fixed one end of each of the two dampers 17 to the two second binding straps 18, completing the installation of the steel component body 19. During the lifting process, the balance chain 3, the balance bar 4, and the hook 13 worked together to keep the steel component body 19 stable and prevent swaying. When encountering strong airflow during lifting, the dampers 17 absorbed and buffered the swaying of the steel component body 19, preventing excessive swaying and further improving the stability during lifting.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
