Description

A device for suspending lifting slings at heights Technical Field

[0001] This invention relates to a device that facilitates suspension at heights, and in particular to a device that allows for the safer and more convenient suspension of lifting slings at heights. Background Technology

[0002] In the ship repair industry, pipeline research and installation work may involve various ship types, and even ships of the same type may vary in size. Cranes are essential during both ship repair and pipeline assembly. When the anchor point is high, suspending cranes at heights presents a significant challenge. Currently, there are two main methods: one is to erect scaffolding, with workers climbing it to reach the designated anchor point; the other is to use A-frame ladders or high-rise ladders, with workers climbing up to hang the crane. Firstly, working at heights poses safety hazards, especially during ascent and descent. Secondly, erecting scaffolding requires material preparation, increasing work time. Sometimes, after the crane is attached, the assembled scaffolding interferes with pipeline installation, necessitating dismantling and re-erecting the scaffolding, which not only delays the project but also increases costs. Summary of the Invention

[0003] The purpose of this invention is to provide a device that can suspend lifting slings at high altitudes with high work efficiency and a high safety factor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for facilitating the suspension of lifting slings at heights includes a gripper, which comprises a gripping assembly, a control assembly, and a telescopic assembly. One end of the telescopic assembly is connected to the gripping assembly, and the other end is connected to the control assembly. The control assembly controls the gripping assembly via a wire rope, which is connected to the gripping assembly, passes through the interior of the telescopic assembly, and is then connected to the control assembly.

[0006] Furthermore, the gripper includes a hook, which includes a cross hook and a telescopic assembly, the cross hook being fixed to the telescopic assembly.

[0007] Furthermore, the gripping assembly includes a cross hook and a gripping hook, with the gripping hook fixed on the cross hook; the gripping hook is provided with a first fixed pulley, the cross hook is provided with a first auxiliary rod and a second auxiliary rod, the cross hook is provided with a first fixing ring and a second fixed pulley inside, the wire rope is fixed on the gripping hook, passes over the first and second fixed pulleys and enters the interior of the cross hook and passes through the first fixing ring; the cross hook is provided with a first locking hole.

[0008] Furthermore, the telescopic assembly consists of multiple uprights, one end of which is provided with a locking body that can engage with a locking hole; the other end of the upright is provided with a locking hole, and the inside of the upright is provided with a fixing ring, which can allow a steel wire rope to pass through.

[0009] Furthermore, the control assembly includes a third fixed pulley, a first torsion spring, and a handle. The third fixed pulley is fixed to the telescopic assembly, and the wire rope is fixed to the handle via the third fixed pulley. The handle is hinged to the telescopic assembly via the first torsion spring.

[0010] Furthermore, the gripper hook includes a first gripping part and a second gripping part, which are hinged together by a second torsion spring.

[0011] Furthermore, the cross hook is generally semi-circular, with one end being tapered and the other end having a locking hole.

[0012] Furthermore, the card bodies are connected by a reset spring.

[0013] Furthermore, the fixing ring is secured by a rubber band.

[0014] Furthermore, the handle is equipped with an adjustment ring, which enables fine-tuning of the wire rope.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] This invention enables the lifting sling to be lowered to a high position using a grab, and then the hook is used to move the sling's buckle to the same height, facilitating the passage of the hand-operated hoist through the sling. The height reachable by the grab depends on the number of uprights, and the length of the wire rope can be fine-tuned by adjusting the position of the adjusting ring, making it easier for the lifting sling to reach the designated location. This invention, through the cooperation of the grab and hook, eliminates the need for workers to climb to heights or erect scaffolding, reducing project costs, saving manpower, and eliminating the possibility of falls from heights during high-altitude operations.

[0027] Referring to Figures 1 to 10, a device for facilitating the suspension of lifting slings at heights includes a gripper 1, which includes a hook 2. The gripper 1 comprises a gripping assembly 11, a control assembly 12, and a telescopic assembly 13. One end of the telescopic assembly 13 is connected to the gripping assembly 11, and the other end is connected to the control assembly 12. The control assembly 12 controls the gripping assembly 11 via a steel wire rope 3, which is connected to the gripping assembly 11, passes through the telescopic assembly 13, and then connects to the control assembly 12. The lifting sling 4 is secured by the gripping assembly 11, and the lifting sling 4 is delivered to the target location via the telescopic assembly 13. Finally, the lifting sling 4 is detached from the gripping assembly 11 by the control assembly 12, allowing the lifting sling 4 to span across the target position.

[0028] The hook 2 includes a cross hook 111 and a telescopic assembly 13. The cross hook 111 is fixed to the telescopic assembly 13. The cross hook 111 is generally semi-circular, with one end tapered and the other end having a locking hole 22. The cross hook 111 cooperates with the upright 131, and the locking body 132 on the upright 131 is fixed in the locking hole 22, so that the height of the hook 2 changes with the number of uprights 131. After the lifting sling 4 is positioned across the target location, the hook 2 is used to hook the upper part of the buckle of the lifting sling 4, so that the two buckles are roughly at the same horizontal line, so that the hand chain hoist can hook both buckles at the same time, safely and efficiently saving a lot of manpower and time costs.

[0029] The gripping assembly 11 includes a cross hook 111 and a gripping hook 112, with the gripping hook 112 fixed to the cross hook 111. The gripping hook 112 is equipped with a first fixed pulley 113, and the cross hook 111 is equipped with a first auxiliary rod 114 and a second auxiliary rod 115. The cross hook 111 contains a fixing ring 116 and a second fixed pulley 117, with the fixing ring 116 secured by a rubber band 118. When the lifting sling 4 reaches the target position, the cross hook 111, being semi-circular, directly straddles the pipe or beam, allowing the lifting sling 4 to cross over and rest on it. The lifting sling 4 will then pass sequentially through the first auxiliary rod 114 and the second auxiliary rod 115, facilitating easier placement of the lifting sling 4 on the beam or pipe. The cross hook 111 has a locking hole 22, which engages with a locking body 132 on the upright 131, fixing the cross hook 111 to the upright 131.

[0030] The telescopic assembly 13 consists of multiple uprights 131. One end of each upright 131 has a locking body 132 that engages with a locking hole 22. The other end of each upright 131 has a locking hole 22. Inside each upright 131 is a fixing ring 116 through which a steel wire rope 3 can pass. The locking bodies 132 are connected by a return spring. The number of uprights 131 determines the height of the gripper 1, preventing workers from climbing to work at heights. Before the locking body 132 enters the locking hole 22, the return spring is compressed. When the locking body 132 reaches the locking hole 22, the return spring resets the locking bodies 132 on both sides, engaging them into the locking hole 22, thus fixing the multiple uprights 131 together.

[0031] The control component 12 includes a third fixed pulley 122, a first torsion spring 123, and a handle 124. The third fixed pulley 122 is fixed on the telescopic component 13. The operator can control the handle 124, and the handle 124 transmits force to the hook 112 through the wire rope 4, thereby controlling the opening and closing of the hook 112 and achieving precise delivery of the lifting sling 4.

[0032] One end of the wire rope 3 is connected to the hook 112, then passes over the first fixed pulley 113 and the second fixed pulley 117 and enters the inside of the hook 111, passes through the fixing ring 116, and then enters the fixing ring 116 in the upright 131. Finally, the wire rope 3 passes through the third fixed pulley 122 and is fixed to the handle 124. The handle 124 is hinged to the telescopic assembly 13 by the first torsion spring 123.

[0033] The grab hook 112 includes a first gripping part 1121 and a second gripping part 1122, which are hinged together by a second torsion spring 1123. When the operator presses down the handle 124, the first gripping part 1121 and the second gripping part 1122 separate. The hook 2 is used to hook the lifting sling 4 out of the grab hook 112. The handle 124 is released, the first gripping part 1121 and the second gripping part 1122 close, the grab 1 is withdrawn, and the hook 2 is used to continue to pull the lifting sling 4 downward until the buckles at both ends of the lifting sling 4 are at the same horizontal position. Then the hook 2 is withdrawn, and the hand chain hoist is used to hook the buckles at both ends of the lifting sling 4 at the same time to complete the suspension of the lifting sling 4.

[0034] The handle 124 is equipped with multiple adjusting rings 1241. The steel wire rope 3 can be fine-tuned by connecting to different adjusting rings 1241. If the length of the steel wire rope 3 affects the control of the handle 124 over the hook 111, the connection position of the steel wire rope 3 can be changed to another adjusting ring 1241, thereby achieving fine-tuning of the steel wire rope 3.

[0035] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
