DETAILED DESCRIPTION
[0019] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.
[0020] Figure 1-Figure 4 It is the best embodiment of the utility model, and the following Figure 1-Figure 4 The utility model is further described.
[0021] See attached Figure 1-Figure 4 A cable tension-adjustable pay-off device comprises a pay-off roller 1, two bases 2 are arranged on the bottom surface of the pay-off roller 1, the two bases 2 are arranged at intervals, and two pulleys 3 are rotatably connected inside each base 2 at intervals. A connecting rod 5 is arranged between the two bases 2, and the connecting rod 5 has two connecting rods 5 arranged on both sides of the pay-off roller 1. The two bases 2 are connected by the connecting rod 5, and an adjusting component and a guiding component are arranged on the top surface of the base 2, and the adjusting component is connected to the guiding component.
[0022] In this embodiment, the middle part of the pay-off roller 1 is a winding drum for winding the cable, and both ends of the winding drum are installed with a disk that is directly larger than the winding drum. Each disk is respectively arranged between the pulleys 3 on the corresponding side, and the lower part of each disk is supported on the two pulleys 3 on the corresponding side.
[0023] The adjusting component includes a three-way pipe 4, which is arranged on the top surface of the base 2. Two first pistons 14 are slidably connected inside the two opposite ends of the three-way pipe 4. One end of the first piston 14 is fixedly connected to a moving column 13, and one end of the moving column 13 is fixedly connected to a fixed rod 7. One end of the fixed rod 7 passes through the three-way pipe 4 and extends to the outside of the three-way pipe 4 and is fixedly connected to a brake pad 8.
[0024] Specifically, the adjusting component also includes a second piston 15, which is slidably connected to the inside of the other end of the tee pipe 4, and one end of the second piston 15 is fixedly connected to a threaded rod 16, which is threadedly connected to the end of the corresponding end of the tee pipe 4, and one end of the movable column 13 is fixedly connected to a rebound part.
[0025] In this embodiment, through the set threaded rod 16, the staff can rotate the threaded rod 16, the threaded rod 16 rotates and drives the second piston 15 to move inside the three-way pipe 4, thereby squeezing the hydraulic oil inside the three-way pipe 4, and the hydraulic oil will squeeze the first piston 14 at this time. After being squeezed, the first piston 14 pushes the movable column 13 to move outward, and then the movable column 13 drives the brake pad 8 to move through the fixed rod 7, and then the two brake pads 8 are in contact with and pressed against the inner side of the two discs of the pay-off roller 1. As the contact between the two brake pads 8 and the pay-off roller 1 becomes closer and closer, the resistance encountered by the pay-off roller 1 during rotation increases, and the pulling force on the cable will increase at this time, and then the tension will also increase. If the tension of the cable needs to be reduced, the reverse operation can be performed.
[0026] Specifically, the resilient member includes a return spring 12, which is sleeved outside the fixed rod 7 on the corresponding side, and two ends of the return spring 12 are respectively connected to the movable column 13 on the corresponding side and one end of the three-way pipe 4.
[0027] In this embodiment, when the moving column 13 moves, it will squeeze the reset spring 12. When the moving column 13 loses the squeezing force, the potential energy of the reset spring 12 is released to drive the moving column 13 to reset.
[0028] Specifically, the guide component includes a fixed block 11, which is fixedly connected to the top surface of the base 2. A guide column 10 is fixedly connected to one side of the fixed block 11. A guide groove 6 is opened on the inner end surface of the disc of the pay-off roller 1, and the guide column 10 slides into the guide groove 6.
[0029] In this embodiment, when the pay-off roller 1 rotates, the pay-off roller 1 rotates on the guide column 10 through the guide groove 6. The pay-off roller 1 is guided by the two guide columns 10 when the pay-off roller 1 rotates to prevent the pay-off roller 1 from deviating.
[0030] Specifically, the guide component further includes a fixing seat 9 , which is fixedly connected to the top surface of the fixing block 11 , and the fixing seat 9 is fixedly connected to the three-way pipe 4 .
[0031] In this embodiment, the fixing seat 9 can support the three-way pipe 4 to ensure the stability of the three-way pipe 4 during use.
[0032] Specifically, the outer end of the threaded rod 16 is fixedly connected with a knob 17 .
[0033] In this embodiment, by means of the knob 17 , a worker can hold the knob 17 and rotate the threaded rod 16 , so that the threaded rod 16 drives the second piston 15 to rotate and squeeze the hydraulic oil inside the three-way pipe 4 .
[0034] The working principle and use process of the utility model are as follows: when in use, through the set pay-off roller 1, the staff can wind one end of the cable on the pay-off roller 1 onto the take-up machine when paying out the cable, and the cable is reeled up by the take-up machine. When reeling up, the cable on the pay-off roller 1 is pulled, thereby driving the pay-off roller 1 to rotate on the two pulleys 3, and when rotating, through the cooperation of the guide groove 6 and the guide column 10, the two guide columns 10 guide the pay-off roller 1 when it rotates, so as to prevent the pay-off roller 1 from deviating. When it is necessary to adjust the tension of the cable, the staff can rotate the threaded rod 16 through the knob 17, and the threaded rod 16 rotates and drives the second piston 15 to move inside the three-way pipe 4 , thereby squeezing the hydraulic oil inside the three-way pipe 4, at this time the hydraulic oil will squeeze the first piston 14, and after being squeezed, the first piston 14 pushes the moving column 13 to move inside the three-way pipe 4 and squeeze the return spring 12, so that the moving column 13 drives the brake pad 8 to move through the fixed rod 7, and then the two brake pads 8 are in contact with the pay-off roller 1. As the pressure between the two brake pads 8 and the pay-off roller 1 increases, the resistance to the rotation speed of the pay-off roller 1 increases. At this time, the pulling force on the cable will increase, and then the tension will also increase. If it is necessary to reduce the tension of the cable, the reverse operation can be performed, thereby ensuring the progress of the cable pay-off and achieving the effect of adjusting the cable tension.
[0035] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
