Technical Field

[0001] This utility model relates to the field of tension control technology, specifically to a tension control device for overhead power line crossings on highways. Background Technology

[0002] Electricity is used everywhere in life. Cables are needed in the transmission of electricity, and as the basic carrier of electrical energy, the demand for cables is very large. In the production process of cables, tension adjustment devices are needed to better wind, store or transport the cables.

[0003] Chinese patent CN210558618U discloses a cable tension regulating device, which achieves the effect of regulating cable tension by adjusting the distance between rotating wheels.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: In actual use, the above solutions adjust the cable tension through the transmission process. When the cable is located on the crossing frame, the cable is in a relatively static state, and the above-mentioned devices cannot be used at this time.

[0005] This invention proposes a cable tension control device for highway crossings to solve the problem that the tension of cables cannot be adjusted when they are on the crossing frame. Utility Model Content

[0006] The purpose of this invention is to overcome the problems mentioned in the background art by installing a tension adjustment structure on the cable support, which enables the adjustment of the cable tension even when the cable is in a relatively static state.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0008] A cable tension control device for overhead power line crossings on highways includes a base and a support column connected to its top. Reinforcing members are connected to both sides of the bottom of the support column, and the bottom of the reinforcing members is connected to the base. A support plate is connected to the top of the support column, and a guide component is connected to the top of the support plate for constraining the cable. A lifting component is connected to the top of the support plate for adjusting the cable tension.

[0009] Further defining the above technical solution, the guide component includes a rotating bracket connected to the top of the support plate, a guide wheel rotatably connected to the top of the rotating bracket, and a groove provided on the outer arc surface of the guide wheel, the groove contacting the external cable for constraining the cable.

[0010] Further defining the above technical solution, the top of the support plate is connected to a support member, the top of the support member is connected to a spring platform, the rotating bracket and the guide wheel are symmetrically arranged on both sides of the spring platform, the top of the spring platform is connected to a spring, and the top of the spring is connected to a spring bracket.

[0011] Further defining the above technical solution, the spring platform is provided with a waist-shaped hole, and a pressing component is connected to the bottom of the spring bracket. The bottom of the pressing component is provided with an arc-shaped groove, which contacts the external cable to prevent the cable from loosening.

[0012] Further defining the above technical solution, the lifting component includes a connecting bracket connected to the top of the support plate, an electric telescopic rod connected to the side of the connecting bracket, a transmission component connected to the telescopic end of the electric telescopic rod, a transmission shaft rotatably connected to the transmission component, and rotating connecting rods rotatably connected to both ends of the transmission shaft.

[0013] Further defining the above technical solution, the top of the support plate is connected to a transmission bracket, the transmission bracket is rotatably connected to a transmission connecting rod, and the other end of the transmission connecting rod is rotatably connected to a lifting plate.

[0014] As a further limitation of the above technical solution, the end of the rotating connecting rod away from the electric telescopic rod is rotatably connected to a sliding bracket, and the bottom of the lifting plate is provided with a sliding groove, the inner wall of the sliding groove being slidably connected to the sliding bracket.

[0015] Further defining the above technical solution, the top of the lifting plate is connected to several equally spaced abutment members, the top of which is provided with an arc-shaped recess. The arc-shaped recess contacts and presses against the outer arc surface of the external cable to adjust the cable tension.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Facilitates cable restraint: This device uses the outer arc groove of the guide wheel and the arc groove at the bottom of the pressing part as a combination to restrain the cable in the vertical direction, thereby preventing problems such as falling off or misalignment during cable installation. It improves the restraint effect on the cable while ensuring that the cable has a certain degree of sliding space.

[0018] 2. Cable protection: This device uses an arc-shaped structure to contact the outer arc surface of the cable, which increases the contact area with the outer arc surface of the cable during actual use, thereby preventing the outer protective sheath of the cable from cracking.

[0019] 3. Easy to adjust: This device can adjust the height of the lifting plate and then squeeze the outer arc side of the cable through the abutment, thereby increasing the tension of the cable and preventing problems such as the cable loosening on the support frame. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0027] Example 1: This example provides a power line tension control device for highway crossings, such as... Figure 1-4 As shown, the system includes a base 1 and a support column 2 connected to its top. Reinforcing members 3 are connected to both sides of the bottom of the support column 2. The bottom of the reinforcing members 3 is connected to the base 1. A support plate 4 is connected to the top of the support column 2. A guide member 5 is connected to the top of the support plate 4 for constraining the cable. A lifting member 6 is connected to the top of the support plate 4 for adjusting the tension of the cable.

[0028] The guide component 5 includes a rotating bracket 501 connected to the top of the support plate 4. A guide wheel 502 is rotatably connected to the top of the rotating bracket 501. The outer arc surface of the guide wheel 502 is provided with a groove, which contacts the external cable to constrain the cable.

[0029] The top of the support plate 4 is connected to a support member 503, and the top of the support member 503 is connected to a spring platform 504. The rotating bracket 501 and the guide wheel 502 are symmetrically arranged on both sides of the spring platform 504. The top of the spring platform 504 is connected to a spring 506, and the top of the spring 506 is connected to a spring bracket 505.

[0030] The spring platform 504 is provided with a waist-shaped hole, and the bottom of the spring bracket 505 is connected to a pressing member 507. The bottom of the pressing member 507 is provided with an arc-shaped groove 508, which contacts the external cable to prevent the cable from coming loose.

[0031] The lifting component 6 includes a connecting bracket 601 connected to the top of the support plate 4. An electric telescopic rod 602 is connected to the side of the connecting bracket 601. A transmission component is connected to the telescopic end of the electric telescopic rod 602. A transmission shaft 603 is rotatably connected to the transmission component. Rotary connecting rods 604 are rotatably connected to both ends of the transmission shaft 603.

[0032] The specific working principle is as follows: This device can automatically tension the cable when it accidentally comes loose during installation. When the device is in use, the cable passes through the groove of the guide wheel 502, and the top of the cable is pressed by the arc-shaped groove 508 at the bottom of the pressing member 507, thereby achieving the limiting effect of the device on the cable. The guide wheels 502 symmetrically arranged on both sides of the pressing member 507 can effectively improve the restraint effect of the device on the cable.

[0033] When the cable becomes accidentally slack, the combination of the electric telescopic rod 602, the rotating connecting rod 604, and the transmission connecting rod 605 achieves the lifting control effect of the lifting plate 608, thereby achieving the tensioning effect of the cable by this device.

[0034] Example 2: This example provides a power line tension control device for highway crossings, such as... Figure 1-4 As shown, a transmission bracket is connected to the top of the support plate 4, and a transmission connecting rod 605 is rotatably connected to the transmission bracket. The transmission connecting rod 605 is rotatably connected to the center of the rotating connecting rod 604, and a lifting plate 608 is rotatably connected to the other end of the transmission connecting rod 605.

[0035] The rotating connecting rod 604 is rotatably connected to a sliding bracket 606 at one end away from the electric telescopic rod 602. The bottom of the lifting plate 608 is provided with a sliding groove 607, and the inner wall of the sliding groove 607 is slidably connected to the sliding bracket 606.

[0036] The top of the lifting plate 608 is connected to several equally spaced abutment members 609. The top of the abutment member 609 is provided with an arc-shaped recess, which contacts and presses against the outer arc surface of the external cable to adjust the cable tension.

[0037] The specific working principle is as follows: the lifting component 6 is adjusted to tighten the cable when it becomes accidentally loose. The electric telescopic rod 602 extends outward, which drives the transmission shaft 603 to slide horizontally, thereby driving the rotating connecting rod 604 to rotate at an angle. The combination of the rotating connecting rod 604 and the transmission connecting rod 605 enables the lifting plate 608 to slide up and down, thereby achieving the tensioning effect of this device.

[0038] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
