Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope products, and in particular to a steel wire rope tensioning device. Background Art

[0002] Wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. Wire rope consists of steel wire, rope core and grease. Wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying. Wire rope has high strength, light weight, stable operation, not easy to break suddenly, and reliable operation. When lifting, the wire rope needs to be tightened with a tensioning device at the end of the wire rope. After tightening, fold it in half and lock it with a lock.

[0003] The existing tensioning device achieves tensioning through a screw structure, which requires passing one end of the wire rope through a ring buckle at one end of the screw, folding it in half and then locking it with a lock buckle, and then rotating the pipe sleeve on the screw that is threadedly connected to the screw to achieve the movement of the screw and achieve the tensioning function. The tensioning device needs to be hoisted to a high place, and under the influence of the wire rope's own gravity, it is time-consuming and laborious to manually rotate the pipe sleeve, and the work efficiency is low.

The pressure plate 183 squeezes the clamping block 121 to separate the clamping block 121 from the card slot 113, and the cover plates 12 on both sides of the shell 11 are opened. A group of clamping components 2 close to the support plate 13 is the first clamping end, and the other group of clamping components 2 is the second clamping end. The wire rope 5 first passes through the upper surface of the support plate 13 A group of clamping parts 17 near the first clamping end enters the shell body 11, passes through the first clamping end and then passes out of the shell body 11, bypasses the parts that need to hang the wire rope 5, then enters the shell body 11 from the other side of the shell body 11 and passes through the second clamping end and then passes out of the shell body 11, and then passes through another group of clamping parts 17 on the support plate 13, and at the same time clamps the wire rope 5 between the corresponding check plates 16. At this time, the wire rope 5 is installed, and the cover plate 12 is pulled down to engage the clamping block 121 with the clamping groove 113. The cover plate 12 and the shell body 11 are relatively fixed. Taking the manual drive method as an example, the handle is fixedly connected to the interface on the connecting sleeve 31, and the connecting motor 38 is started at the same time. The output shaft of the connecting motor 38 drives the bidirectional screw rod 381 rotates, the upper mounting plate 32 and the lower mounting plate 36 move toward each other, the upper mounting plate 32 drives the driving sleeve 33 to move so that the spline shaft 332 is plugged into the spline groove 342 of the winding wheel 34, the lower mounting plate 36 moves to drive the pawl 37 to cooperate with the ratchet 35, turn the handle, drive the connecting sleeve 31 to rotate, the connecting sleeve 31 drives the driving sleeve 33 to rotate through the connecting shaft 311, the driving sleeve 33 drives the winding wheel 34 to rotate through the spline shaft 332, the traction rope 343 pulls the pull rod 26 to move, the pull rod 26 drives the rotating plate 23 to rotate through the connecting plate 25, the movable clamping block 24 approaches the fixed clamping block 22 until the wire rope 5 is clamped, and the winding wheel 34 is continued to be driven to rotate. Under the traction of 343, the wire feeding assembly 3 of the clamped wire rope 5 can drive the wire rope 5 to move together. During this process, the pawl 37 cooperates with the ratchet 35 to prevent the winding wheel 34 from reversing, and the tilted check plate 16 prevents the wire rope 5 from sliding back. After the wire rope 5 moves a certain distance, the handle is stopped to reverse the connection motor 38, the upper mounting plate 32 and the lower mounting plate 36 move away from each other, the pawl 37 separates from the ratchet 35, the spline shaft 332 separates from the spline groove 342, and the bottom plate 21 is reset under the action of the reset spring 211, driving the pull rod 26 to move, and the pull rod 26 reverses and resets the winding wheel 34 through the traction rope 343. Repeated operations can complete the tensioning of the wire rope 5. After the wire rope 5 is tightened, the cover plate 12 is opened and the wire rope 5 between the second clamping end and the two sets of clamping members 17 on the support plate 13 is taken out, the movable end of the wire rope 5 is pulled to align it with the tensioning end of the wire rope 5 and fasten it with the lock buckle, and then the wire rope 5 at the first clamping end is taken out, so as to prevent more rebound margin caused by directly locking the wire rope 5 and then disassembling the device, and then the piston rod of the cylinder 41 is moved in the opposite direction, and the clamping claw 44 is separated from the hanging component. When the device is in use, the whole device has a compact structure and is not easy to be damaged. The winding wheel 34 is controlled to rotate by the connecting sleeve 31, and the ratchet wheel 35, the ratchet 37 and the clamping assembly 2 are used to realize the tensioning work of the wire rope 5, which saves time and effort. The set check plate 16 can prevent the wire rope 5 from rebounding and improve work efficiency. The rotatable cover plate 12 is faster and easier to operate when fixing or removing the wire rope 5.
