Description

Technical Field

[0001] The utility model relates to the technical field of tension adjusting devices, and more specifically, to a wire rope tension adjusting device. Background Art

[0002] A wire rope is a helical wire bundle formed by twisting steel wires that meet the requirements of mechanical properties and geometric dimensions according to certain rules. First, multiple layers of steel wires are twisted into strands, and then, with the rope core as the center, a certain number of strands are twisted into a helical rope. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing. The wire rope has high strength, light self-weight, stable operation, and is not likely to break suddenly as a whole, and is reliable in work.

[0003] However, when the existing wire ropes are processed and twisted, the tension of the strand ropes will change during transmission. Different tensions of multiple strand ropes result in non-compact and uneven twisting together, affecting the twisting quality of the wire rope, and thus affecting the finished product quality. In the existing patent, a wire rope strand wire tension adjusting device, in the patent authorization number CN212714265U, by setting a tension adjusting mechanism, rotating the handle to make its gear shaft rotate and push the gear shaft engaged and connected on one side to move up and down, so that the tension roller can easily and simply adjust the tension of the strand rope passing through the top surface, thereby adjusting the strand rope tension, making the tension of each strand rope uniform and the formed wire rope of better quality and more compact.

[0004] However, after the adjustment in the patent authorization number CN212714265U, the handle and the gear cover are pushed inward to make the gear cover engage and plug into one end of the gear roller for locking to prevent the pressure on the tension roller from causing it to drop. Since the gear cover and the gear roller need to mesh with each other, precise cooperation between the gear cover and the gear roller is required when pushing the handle, which is inconvenient during the operation process. Therefore, we propose a wire rope tension adjusting device to solve the above existing problems. Summary of the Utility Model

[0036] A tensioning wheel 7 is rotatably connected to the surface of the movable seat 4 away from the guiding head 5.

[0037] A guiding wheel 8 rotatably connected to the bracket 2 is installed on one side of the tensioning wheel 7.

[0038] A tension sensor 9 fixedly connected to the bracket 2 is arranged on the side of the tensioning wheel 7 away from the guiding wheel 8.

[0039] A turning handle 10 is installed at the top of the double-headed screw 3. A receiving groove 12 is opened at the edge of the lower surface of the turning handle 10. A spring 14 is installed inside the receiving groove 12. A baffle 13 slidably connected to the receiving groove 12 is arranged below the spring 14. A positioning rod 11 is fixedly connected to the lower surface of the baffle 13.

[0040] A groove 16 arranged in a ring structure is opened on the upper surface of the bracket 2 corresponding to the turning handle 10. A limiting block 17 arranged in a right triangle structure is fixedly connected to the bottom wall of the groove 16, and a plurality of limiting blocks 17 are annularly arranged in the radial position of the groove 16.

[0041] It should be noted that when the wire rope tension adjusting device is in use, the strands of the wire rope are wound around the tension sensor 9, then pass through the surface of the tensioning wheel 7, pass through the bottom of the guide wheel 8, and then enter the bunching device for twisting. The tension sensor 9 senses the tension of the passing strands, and then the data is displayed on the terminal console. When the tension does not meet the normal value, the turning handle 10 is rotated counterclockwise to drive the double-headed screw 3 to rotate. The guiding stud 5 cooperates with the guiding hole 6 to slide, so that the distance between the two movable seats 4 increases, and the tension of the wire rope by the tensioning wheel 7 is adjusted. At the same time, the bottom end of the positioning rod 11 continuously fits the inclined surface of the limiting block 17 under the cooperation of the spring 14 and the baffle 13 located inside the groove 16 to make a circular motion until the adjustment of the wire rope tension value is completed, so that the side wall of the bottom end of the positioning rod 11 abuts against the right-angle surface of the limiting block 17, preventing the double-headed screw 3 from reversing, and the positioning of the tensioning wheel 7 can be realized without precise cooperation, and the operation is very convenient.

[0042] As Figure 4 shown, a handle 15 is fixedly connected to the outer wall of the positioning rod 11.

[0043] It should be noted that when the tensioning wheel 7 needs to be reset, the positioning rod 11 is lifted upward by using the handle 15, and then the turning handle 10 is rotated to drive the double-headed screw 3 to rotate, which is convenient for operation.

[0044] As Figure 1 shown, the part where the double-headed screw 3 is combined with the fixed base 1 and the bracket 2 is arranged in a smooth surface structure.

[0045] Bearings are installed at the parts where the fixed base 1 and the bracket 2 are combined with the double-headed screw 3.

[0046] It should be noted that the friction between the double-headed screw 3 and the fixed base 1 and the bracket 2 is reduced, and the rotation accuracy of the double-headed screw 3 is ensured.

[0047] As Figure 6 shown, a limiting part fixedly connected to the turning handle 10 is arranged at the bottom opening part of the storage groove 12, and the limiting part abuts against the baffle 13.

[0048] One end of the spring 14 is connected to the baffle 13, and the other end of the spring 14 is connected to the top wall of the storage groove 12.

[0049] It should be noted that by setting the limiting part to block the baffle 13, the baffle 13 is prevented from detaching from the storage groove 12 under the elastic force of the spring 14.

[0050] As Figure 4 shown, the bottom end of the positioning rod 11 fits against the bottom wall of the groove 16, and the side wall of the bottom end of the positioning rod 11 abuts against the right-angle surface of the limiting block 17.

[0051] It should be noted that after adjusting the tension value of the steel wire rope, the bottom side wall of the positioning rod 11 is abutted against the right-angle surface of the limiting block 17 to prevent the double-headed screw 3 from reversing.

[0052] A steel wire rope is wound around the guide pulley 8, the tension pulley 7 and the tension sensor 9.

[0053] During use: Wind the strand of the steel wire rope through the tension sensor 9, then pass through the surface of the tension pulley 7, pass through the bottom of the guide pulley 8 and then enter the bunching device for twisting. The tension sensor 9 senses the tension of the strand, and then the data is displayed on the terminal console. When the tension does not meet the normal value, rotate the handle 10 counterclockwise to drive the double-headed screw 3 to rotate. The guiding head 5 cooperates with the guiding hole 6 to slide, so that the distance between the two movable seats 4 increases, and the tension of the steel wire rope by the tension pulley 7 is adjusted. At the same time, the bottom end of the positioning rod 11 continuously fits against the inclined surface of the limiting block 17 under the cooperation of the spring 14 and the baffle 13 located inside the groove 16 to make a circular motion until the tension value of the steel wire rope is adjusted, and the bottom side wall of the positioning rod 11 is abutted against the right-angle surface of the limiting block 17 to prevent the double-headed screw 3 from reversing.
