Description

Technical Field

[0001] This utility model relates to the field of wire rope production technology, specifically to a tensioning device for wire rope production. Background Technology

[0002] Steel wire ropes are characterized by their ease of use, high tensile strength, long axial dimension, and ability to absorb vibration. They are widely used in tensioning construction. After production, steel wire ropes need to be wound up in a concentrated manner, and the tension of the steel wire rope needs to be adjusted during winding. Tensioning devices adjust the tension of the wire rope to ensure sufficient friction on pulleys or rollers, preventing slippage or derailment due to slack, thus ensuring production continuity. Proper tension reduces frictional resistance between the wire rope and idler rollers, lowering energy consumption and improving production efficiency. However, tensioning devices are not easily assembled or disassembled with the wire rope, limiting the impact of disengagement after tension adjustment and offering limited flexibility in adjusting the tension. Utility Model Content

Each vertical plate has a trapezoidal groove at its top, a threaded rod is provided in the trapezoidal groove, and an adjustment component for adjusting the tension of the steel wire rope is provided in each trapezoidal groove. The adjustment assembly includes a limiting plate and a trapezoidal block on the rear end face of the limiting plate. The trapezoidal block is inserted into a trapezoidal groove. Each trapezoidal block has a screw hole. The limiting plate has a through groove in the middle, and a pulley is provided at the bottom of the through groove. The front end face of the limiting plate has an opening communicating with the through groove. The bottom of the opening has a rotating groove, and the top of the opening has a positioning groove.

A connecting plate is provided at the top of the locking post near the rear end, and a plug is provided at the top of the connecting plate corresponding to the connecting groove.

[0005] Furthermore, the bottom of the vertical plate is welded and fixed to the upper surface of the base plate, and several connecting rods are provided between the two vertical plates, with both ends of the connecting rods welded and fixed to the vertical plates respectively.

[0006] In this invention, the combination of multiple connecting rods increases the stability of the combination between the two vertical plates and increases the resistance to compressive force. The base plate supports the entire device, making it easy to place vertically. Furthermore, the corners of the base plate can be easily fixed to the corresponding locations along the production path of the steel wire rope using external screws, thus increasing the stability of the installation.

[0007] Specifically, a top plate is provided between the tops of the two vertical plates, the threaded rod passes through the top plate and is rotatably connected to the top plate, the bottom of the threaded rod is rotatably connected to the vertical plate, and a crank handle is provided at the top of the threaded rod.

The bottom of the limiting stud is tightly fitted to the outer wall of the vertical plate, and the position of the trapezoidal block is fixed under the action of friction, thereby realizing the position fixation of the adjustment component.

[0011] Furthermore, the limiting plate and the trapezoidal block are integrally formed, and the adjustment components inserted into the two vertical plates are in one group for forward insertion and the other group for reverse insertion.

[0012] In this invention, the adjustment components on the two vertical plates are installed in opposite directions, which makes it convenient for the steel wire rope to pass through the middle of the two adjustment components, so that the two adjustment components move in opposite directions to achieve the adjustment of the steel wire rope tension.

[0013] It is worth noting that the pulley is rotatably connected to the through groove on the limiting plate via a rotating shaft, and the bottom of the card plate is rotatably connected to the rotating groove via a rotating shaft.

When the button is released, the spring returns to its initial position, allowing the insert to extend out of the positioning groove. When the top of the card plate rotates into the positioning groove, the insert engages with the positioning groove, fixing the position of the card plate and increasing the stability of the installation.

The threaded rods adjust the positions of the corresponding limiting plates to adjust the tension of the wire rope between the two vertical plates. The pulley is rotatably connected to the limiting plate, which facilitates the flexible pulling and moving of the wire rope. The clamping plate is rotatably connected to the rotating groove, and the positioning groove on the top of the clamping plate is inserted. With the cooperation of the clamping post with a spring, the clamping post is inserted into the positioning hole to fix the position of the clamping post and prevent the wire rope from detaching from the limiting plate, thus affecting the adjustment of the wire rope tension.

[0025] Specifically, each trapezoidal groove 100 is equipped with an adjustment component 2 for adjusting the tension of the wire rope; It should be noted that the adjustment component 2 includes a limiting plate 20 and a trapezoidal block 21 on the rear end face of the limiting plate 20. The trapezoidal block 21 is inserted into the trapezoidal groove 100. The rear end face of the vertical plate 10 is provided with a sliding groove 101 that communicates with it.

The rear end face of the trapezoidal block 21 is provided with a limiting stud 211 corresponding to the sliding groove 101. The limiting stud 211 is provided with a wing nut 212.

[0026] In this utility model, the trapezoidal block 21 is slidably inserted into the trapezoidal groove 100, which restricts the vertical movement of the limiting plate 20 on the vertical plate 10. The limiting stud 211 passes through the sliding groove 101, and the wing nut 212 is threadedly connected to the limiting stud 211. The bottom of the limiting stud 211 is tightly attached to the outer wall of the vertical plate 10, and the position of the trapezoidal block 21 is fixed under the action of friction, thereby fixing the position of the adjusting component 2.

[0027] Furthermore, the limiting plate 20 and the trapezoidal block 21 are integrally formed structures, and the adjustment components 2 inserted into the two vertical plates 10 are in one group for forward insertion and the other group for reverse insertion.

[0028] In this invention, the adjustment components 2 on the two vertical plates 10 are installed in opposite directions, so that when the steel wire rope passes through the middle of the two adjustment components 2, the two adjustment components 2 move in opposite directions to achieve the adjustment and coordination of the steel wire rope tension.

[0029] It is worth noting that each trapezoidal block 21 is provided with screw holes 210, the limiting plate 20 is provided with a wire passage groove in the middle, a pulley 22 is provided at the bottom of the wire passage groove, the front end face of the limiting plate 20 is provided with an opening communicating with the wire passage groove, the bottom of the opening is provided with a rotating groove 200, the top of the opening is provided with a positioning groove 201, the rotating groove 200 is provided with a card plate 23 for limiting and intercepting the wire rope, the positioning groove 201 is provided with a slot 2010 in the middle, the top of the slot 2010 is provided with a connecting groove 2011, the positioning groove 201 is provided with a locking post 24, the rear end of the locking post 24 is provided with a spring 240, the top of the locking post 24 is provided with a connecting plate 241 near the rear end, and the top of the connecting plate 241 is provided with a plug rod 242 corresponding to the connecting groove 2011.

The distance between the rotating groove 200 and the positioning groove 201 is adapted to the length of the clamping plate 23.

[0031] In this invention, the pulley 22 facilitates the flexible pulling and movement of the wire rope through which it passes. The clamping plate 23 rotates and engages with the rotating groove 200. When the top of the clamping plate 23 is inserted into the positioning groove 201, the opening on the limiting plate 20 is sealed, preventing the wire rope from being restricted in its range of motion after the tension is adjusted, and preventing the wire rope from detaching from the limiting plate 20. In addition, the locking post 24 is slidably inserted into the positioning groove 201. The locking post 24 has a spring 240 extending into the slot 2010.

When the button 243 is pressed, the insertion rod 242 slides to the bottom of the connecting groove 2011, and the locking post 24 compresses the spring 240. The top of the locking post 24 disengages from the positioning hole 230, allowing the locking plate 23 to rotate out of the positioning groove 201, thus opening the opening on the limiting plate 20. When the button 243 is released, the spring 240 returns to its initial position, allowing the locking post 24 to extend out of the positioning groove 201. When the top of the locking plate 23 rotates into the positioning groove 201, the locking post 24 is inserted into the positioning groove 201, thus fixing the position of the locking plate 23 and increasing the stability of the installation.

[0033] In this embodiment, the tensioning device for wire rope production is first used by assembling and fixing the vertical plate 10 and the base plate 1 together. The two vertical plates 10 are fixed together by multiple connecting rods 11. The threaded rod 3 with a crank handle 30 passes through the top plate 12 and extends into the trapezoidal groove 100. The bottom of the threaded rod 3 is rotatably connected to the vertical plate 10. The limiting plate 20 is inserted into the trapezoidal groove 100 on the vertical plate 10 through the trapezoidal block 21. The opening on one limiting plate 20 is at the top, and the opening on the other limiting plate 20 is at the bottom. The locking post 24 with a spring 240 is inserted into the slot 2010.

The bottom of the locking plate 23 with a positioning hole 230 is rotatably connected to the rotating groove 200, and the top is slidably inserted into the positioning groove 201. When the produced wire rope needs to be wound up, the base plate 1 is fixed to the position where the wire rope passes through the production path using external screws. One end of the wire rope passes through the through groove on the limiting plate 20 inserted in the forward direction on one vertical plate 10, and then through the through groove on the limiting plate 20 inserted in the reverse direction on another vertical plate 10. When the wire rope enters the through groove, it enters through the opening on the limiting plate 20. The clamping plate 23 opens, allowing the through groove to connect with the outside through the opening. After the wire rope is in contact with the pulley 22, rotate the clamp plate 23 and press the button 243. The clamp post 24 and the insertion rod 242 are stored in the corresponding slots 2010 and connecting slots 2011. The top of the clamp plate 23 is inserted into the positioning slot 201. Release the button 243. With the cooperation of the spring 240, the clamp post 24 extends out from the slot 2010. The end of the clamp post 24 is inserted into the positioning hole 230 to fix the position of the clamp plate 23. The two limiting plates 20 restrict the position of the wire rope. Depending on the tightness of the wire rope winding, rotating the two cranks 30 causes the two limit plates 20 to move away from each other. With the cooperation of the pulley 22, the tension of the wire rope is increased, and the corresponding wire rope is tightly wound. Rotating the cranks 30 in the opposite direction causes the two limit plates 20 to move closer to each other, reducing the tension between the wire ropes. The wing nut 212 is threadedly connected to the limit stud 211, and the end of the wing nut 212 is tightly fitted with the vertical plate 10. Under the action of friction, the position of the limit plate 20 is fixed.
