Description

Technical Field

[0001] The utility model belongs to the technical field of power cable tensioning equipment, in particular to a tensioning device for power cable installation. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. During the high-speed cable production process, the tensioning device serves as a buffer device between the pay-off stand and the production equipment. In the event of an emergency stop, if the pay-off stand has a small tension, the wire will be tangled due to inertia.

[0003] The existing public patent (publication number: CN219801685U) discloses a cable tensioning device, which solves the problem that when the tensioning assembly is adjusting the tension of cables of different thicknesses, the thinner cable will be constantly rubbed on the surface of the tensioning wheel when adjusting the wider tensioning wheel surface. After a long period of friction, the contact surface between the cable and the tensioning wheel is prone to wear, thereby affecting the use of the cable. However, there are still problems:

[0004] Since the pitch of the lead screw is large, in actual use, when adjusting, the tension wheel cannot be fine-tuned due to the fixed pitch. During the adjustment process, it will be too tight or too loose, which is not easy to adjust fine-tuning;

[0005] When facing cables of different thicknesses, the depth of the tension wheel's cable groove is fixed, but if the cable is too thick, it is easy for it to become derailed during transmission.

[0006] Therefore, the utility model designs a tensioning device for power cable installation to solve the technical problems existing in the prior art. Utility Model Content

[0023] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0024] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0025] Embodiment 1, a tensioning device for installing a power cable, comprising a device body 1 and a moving block 2, characterized in that:

[0026] The device body 1 is slidably connected with a moving block 2, and the moving block 2 is driven by a power device;

[0027] The moving block 2 is provided with a sliding groove 3, an adjusting plate 4 is slidably connected in the sliding groove 3, a fine-tuning screw 5 rotatably connected to the adjusting plate is threadedly connected to the moving block 2, and a tensioning wheel 6 is rotatably connected to the adjusting plate;

[0028] The moving block 2 is fixedly connected to two groups of connecting plates 7 which are slidably connected to the moving block 2. The two groups of connecting plates 7 are provided with limiting holes 8 corresponding to the tensioning wheel 6.

[0029] The main body is rotatably connected with two sets of transmission wheels 9;

[0030] The power device includes a main body rotatably connected to a transmission screw 10 threadedly connected to the moving block 2, the main body is provided with a motor 11, the transmission screw 10 is driven by the motor 11, and the motor 11 is electrically connected to the controller;

[0031] A retractable plate 12 is provided between the sliding groove 3 and the adjusting plate 4 , and a fine-tuning handle 17 is provided at one end of the fine-tuning screw 5 .

[0032] When in use, the cable passes through one set of transmission wheels 9, through one set of limiting holes 8, around the tension wheel 6, out of the other set of limiting holes 8, and through another set of transmission wheels 9, thus completing the cable threading task;

[0033] During tensioning, the motor 11 is driven to drive the transmission screw to rotate, so that the movable plate moves vertically along the device body 1 to complete the initial tensioning adjustment of the cable. Then, fine-tuning is performed according to the tensioning condition of the cable. The fine-tuning handle 17 is rotated to drive the fine-tuning screw 5 to move, and the adjustment plate 4 moves along the sliding groove 3 to fine-tune the tensioning wheel 6 to ensure that the cable is tensioned to the optimal state.

[0034] When the adjusting plate 4 is moved, the two groups of connecting plates 7 also move accordingly to ensure that the limiting holes 8 are set correspondingly to the tensioning wheel 6. The limiting holes 8 prevent the cable from being separated from the tensioning wheel 6 during the transmission process.

[0035] Embodiment 2, based on embodiment 1, two groups of auxiliary plates 13 are slidably connected in the limiting hole 8, a plurality of springs 14 are arranged between the two groups of auxiliary plates 13 and the limiting hole 8, and auxiliary rollers 15 are rotatably connected to the two groups of auxiliary plates 13;

[0036] The transmission wheel 9 and the tension wheel 6 are both provided with a wire groove 16 , and the outer opening width of the wire groove 16 is greater than the width of the limiting hole 8 .

[0037] When in use, a spring 14 is provided between the limiting hole 8 and the auxiliary plate 13, and is rotatably connected to the auxiliary roller 15 on the auxiliary plate 13, so that the cable passes between the two sets of auxiliary rollers 15. Under the action of the spring 14, the two sets of auxiliary rollers 15 are always in contact with the cable, and under the action of the auxiliary rollers 15, the transmission smoothness is increased.

[0038] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
