Description

Technical Field

[0001] The utility model relates to the technical field of hook rigging, in particular to a safety hook rigging with a handle. Background Art

[0002] Hook rigging is a combination of tools used for lifting and moving heavy objects. It mainly consists of hooks and various ropes. The hook is usually made of high-strength metal, which is durable and has a strong load-bearing capacity. The rope can be a wire rope, synthetic fiber rope, etc., which is used to connect the hook and the heavy object. Hook rigging is widely used in industry, construction, logistics and other fields. It can lift heavy objects safely and reliably. When using it, you need to select the appropriate hook rigging according to the weight and shape of the heavy object, and strictly abide by the operating procedures to ensure operation safety.

[0003] Existing technologies include a utility model with publication number CN202337635U, which discloses a safety hook rigging with a handle, belonging to the field of mechanical design. The safety hook with a handle comprises a lifting part, a hook body, a locking pin, and a handle. The upper end of the lifting part is a lifting ring with a circular hole, with a hexagonal prism connecting the lower end to the locking tongue in the middle. The upper end of the hook body has a vertical groove, and the locking tongue is inserted into the vertical groove of the hook body and riveted to the hook body through a connecting shaft. A locking pin is provided between the upper end of the hook body and the front end of the handle. One end of the locking pin has a cylindrical section, which is inserted into the spring and installed in the hole at the front end of the handle. The cylindrical section has a thread. The other end of the locking pin is a rectangular parallelepiped plane with grooves on its upper and lower sides. The top rectangular parallelepiped plane is clamped by the notch on the locking tongue. The handle is fixed to the hook body by welding. The locking pin is slid to disengage the safety by moving the front end plane of the locking pin away from the notch of the locking tongue, and then the locking tongue can be adjusted to rotate.

[0004] At present, most safety hook riggings are locked by springs. However, after long-term use, the springs are prone to fatigue, which can easily cause the safety hook rigging to loosen, and then easily cause the hoisted workpiece to slip, posing certain safety hazards and requiring improvement. Summary of the Invention

A pull handle 45 is fixedly connected to the surface of the buckle sleeve 43. A limit block 47 is fixedly connected to the upper surface of the hook 3. The buckle sleeve 43 is sleeved on the limit block 47. An auxiliary device 5 is arranged on one side of the hook 3 close to the base 41. This solution simplifies the connection of the hook sling and effectively reduces the probability of loosening of the hook sling during use, avoids the situation of the hoisted workpiece slipping, reduces the safety hazards of the hook sling during use, and facilitates the normal use of the hook sling.

[0023] Specifically, a threaded hole 44 is opened on the surface of the buckle sleeve 43. A positioning bolt 46 is threadedly connected to the inner wall of the threaded hole 44. The positioning bolt 46 can ensure that the buckle sleeve 43 is stably sleeved on the limit block 47.

[0024] In this embodiment: a guiding groove 48 is opened on the surface of the control rod 42. A convex block 49 is fixedly connected to the inner wall of the buckle sleeve 43. The convex block 49 slides with the inner wall of the guiding groove 48 to limit the displacement of the buckle sleeve 43 now.

[0025] Specifically, a positioning block 412 is fixedly connected to one end of the shaft rod 410. A torsion spring 411 is sleeved on the shaft rod 410. The two ends of the torsion spring 411 are respectively fixedly connected to the base 41 and the positioning block 412. After completing the hoisting operation, turn to loosen the positioning bolt 46, and then pull the pull handle 45 in the direction away from the limit rod. The pull handle 45 then drives the buckle sleeve 43 to disengage from the limit rod. Then release the pull handle 45. The torsion spring 411 drives the positioning block 412, the shaft rod 410 and the control rod 42 to reset. Then the control rod 42 drives the buckle sleeve 43 to move away. Then the cable can be removed.

[0026] Specifically, the cross-section of the limit block 47 is rectangular, and the cross-section of the buckle sleeve 43 is in the shape of a figure-eight.

[0027] In this embodiment: The auxiliary device 5 includes a support rod 51. The support rod 51 is fixedly connected to the hook 3 in the direction close to the base 41.

When in use, tie the workpiece to be lifted with a cable, then set the cable on the hook 3, pull the pull handle 45 to drive the control rod 42 to rotate through the buckle sleeve 43. The control rod 42 drives the positioning block 412 to rotate through the shaft rod 410, and the torsion spring 411 deforms under force. When the control rod 42 abuts against the support plate 52, pull the pull handle 45 in the direction away from the control rod 42. The pull handle 45 then drives the buckle sleeve 43 to be sleeved on the limit block 47. Then rotate the positioning bolt 46 to complete the positioning of the buckle sleeve 43, and then the lifting operation can be carried out.

[0028] Specifically, the support rod 51 is arc-shaped, and the edge of the support plate 52 is rounded to ensure the normal use of the equipment.

[0029] Working principle: When in use, tie the workpiece to be lifted with a cable, then set the cable on the hook 3, pull the pull handle 45 to drive the control rod 42 to rotate through the buckle sleeve 43. The control rod 42 drives the positioning block 412 to rotate through the shaft rod 410, and the torsion spring 411 deforms under force. When the control rod 42 abuts against the support plate 52, pull the pull handle 45 in the direction away from the control rod 42. The pull handle 45 then drives the buckle sleeve 43 to be sleeved on the limit block 47. Then rotate the positioning bolt 46 to complete the positioning of the buckle sleeve 43, and then the lifting operation can be carried out. After the lifting operation is completed, rotate and loosen the positioning bolt 46, then pull the pull handle 45 in the direction away from the limit rod.
