Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire rope slings, in particular to a wire rope sling length adjuster. Background Art
[0002] Wire rope slings are processed from steel wire rope and are primarily used for lifting, hauling, tensioning, and load-bearing. They feature high strength, light weight, stable operation, and resistance to sudden breakage, making them widely used in industries such as steel, chemicals, transportation, and ports. Wire rope slings are made from materials including phosphate-coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, and smooth steel wire rope. Galvanized steel wire rope is corrosion-resistant, while phosphate-coated steel wire rope offers both wear and corrosion resistance.
[0003] However, when using existing wire rope slings, the hook is usually fixed on the outside of the wire rope sling, so that the wire rope sling forms two strands, which improves strength and safety performance. However, when adjusting the length of the wire rope sling, the hook is fixed at a fixed position on the wire rope sling, and the hook cannot be adjusted as the length of the wire rope sling changes, which has a certain impact on the use of the wire rope sling. Therefore, a wire rope sling length adjuster is provided. Utility Model Content
[0004] The main purpose of the utility model is to provide a length adjuster for a wire rope sling. The utility model solves the problem that the existing wire rope sling cannot adjust the position of the hook according to the length of the wire rope sling when in use by arranging a sleeve frame, a threaded sleeve, an arc plate, a rubber block, a support sleeve and a threaded groove.
[0005] The cam is connected to the upper end of the driving mechanism, and the cam is connected with the driving mechanism by the cam, and the cam is connected with the driving mechanism by the cam.
[0006] By adopting the above technical solution, when the length of the wire rope sling body needs to be adjusted, the threaded sleeve outside the arc plate is rotated, and then the threaded sleeve moves through the arc plate and the threaded groove outside the support sleeve, so that the threaded sleeve moves to the outside of the support sleeve, so that the arc plate is separated from the wire rope sling body, and then the external controller causes the motor in the fixed frame to convert the received electrical energy into mechanical energy. The motor drives the driving rod on the coupling to rotate, and the wire rope sling body outside the driving rod moves, thereby facilitating the adjustment of the length of the wire rope sling body;
[0007] When the length of the wire rope sling body is adjusted, the hook moves outside the wire rope sling body, and then the sleeve is pulled to move outside the wire rope sling body, so that the bottom of the sleeve is tightly connected with the hook, and then the threaded sleeve on the support sleeve outside the sleeve is rotated, and then the threaded sleeve moves to the surface of the arc plate through the support sleeve and the threaded groove on the surface of the arc plate, and then the rubber block in the arc plate contacts the surface of the wire rope sling body, so that the sleeve is fixed to the outside of the wire rope sling body, thereby facilitating the fixation of the hook outside the wire rope sling body.
[0008] Specifically, a support plate is welded to the bottom of the fixing frame, and a pulley rod for moving the wire rope sling body is rotatably connected to the inner side of the support plate, and a fixing block for limiting the wire rope sling body is fixed to the outer side of the pulley rod by screws.
[0009] By adopting the above technical solution, when the motor drives the drive rod outside the coupling to rotate, the drive rod drives the wire rope sling body to retract and extend, and at the same time the wire rope sling body moves outside the pulley rod inside the support plate, and the fixed block outside the pulley rod limits the wire rope sling body, thereby preventing the wire rope sling body from being offset during retraction and extension.
[0010] Specifically, a bearing seat is fixed by screws on the inner side of the fixing frame to ensure stable rotation of the driving rod.
[0011] By adopting the above technical solution, when the driving rod in the fixed frame rotates, the end of the driving rod away from the coupling is clamped with the bearing seat, thereby improving the rotation stability of the driving rod.
[0012] Specifically, the surface of the threaded sleeve is provided with convex blocks for increasing the surface friction of the threaded sleeve.
[0013] By adopting the above technical solution, when the threaded sleeve is rotated, the protruding particles outside the threaded sleeve increase the friction force on the surface of the threaded sleeve, making it easier for the threaded sleeve to move outside the support sleeve and the arc plate.
[0014] Specifically, the input end of the motor is electrically connected to the power supply end of the external power supply.
[0015] By adopting the above technical solution and connecting to an external power source, the electrical device can work normally.

The inner side of the arc plate 11 is bonded with a rubber block 14 for increasing the surface friction of the wire rope rigging body 6.
[0027] During use, when the length of the wire rope sling body 6 needs to be adjusted, the threaded sleeve 16 outside the arc plate 11 is rotated, and then the threaded sleeve 16 moves through the arc plate 11 and the threaded groove 13 outside the support sleeve 15, so that the threaded sleeve 16 moves to the outside of the support sleeve 15, so that the arc plate 11 is separated from the wire rope sling body 6, and then the external controller causes the motor 1 in the fixing frame 3 to convert the received electrical energy into mechanical energy, and the motor 1 drives the driving rod 5 on the coupling 2 to rotate, and the wire rope sling body 6 outside the driving rod 5 moves, thereby facilitating the adjustment of the length of the wire rope sling body 6;
[0028] When the length of the wire rope sling body 6 is adjusted, the hook 10 moves outside the wire rope sling body 6, and then pulls the sleeve 12 to move outside the wire rope sling body 6, so that the bottom of the sleeve 12 is tightly connected with the hook 10, and then the threaded sleeve 16 on the support sleeve 15 outside the sleeve 12 is rotated, and then the threaded sleeve 16 moves to the surface of the arc plate 11 through the support sleeve 15 and the threaded groove 13 on the surface of the arc plate 11, and then the rubber block 14 in the arc plate 11 contacts the surface of the wire rope sling body 6, so that the sleeve 12 is fixed to the outside of the wire rope sling body 6, thereby facilitating the fixation of the hook 10 outside the wire rope sling body 6.
