Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a hardware string for high-voltage lines. Background Art

[0002] The main function of the hardware string is to connect and combine various devices in the power system to transfer mechanical and electrical loads or play a certain protective role. The hardware string is composed of hardware, used to hang or tighten the ground wire, and can withstand the specified mechanical load.

[0003] The existing Chinese public patent CN216056232U discloses a cable connection hardware string. By installing an adjustment ring, the circuit connection can be adjusted by adjusting the length of the adjustment ring when the cable is connected, without reinstalling a new hardware string, which facilitates the installation of the hardware string. During the process of installing the cable, when the connection length between the pole and the cable needs to be adjusted, the personnel needs to press the lock pin in the adjustment ring into the groove, and then push the telescopic rod or rotate the telescopic rod so that the length and angle between the cable and the pole meet the connection requirements. However, when the above-mentioned device presses the lock pin back into the groove, since the two ends of the adjustment ring are pulled by the pole and the cable respectively, the force exerted on the lock pin by the sleeve and the telescopic rod is relatively large, resulting in the personnel being unable to press the lock pin back due to excessive resistance. The personnel need to pull the cable to make the adjustment ring in a relaxed state before adjusting it, which increases the difficulty and risk factor of high-altitude operations.

[0036] A connecting rod 13 that can move up and down is movably embedded on the outer side of the rotating sleeve 12, and an insert 14 is fixedly connected to the lower end of the connecting rod 13 corresponding to the inside of the rotating sleeve 12, and the insert 14 can be embedded between two adjacent tooth blocks 11, and the outer side of the insert 14 is movably abutted with two symmetrically distributed limit baffles 32, and the connection between the limit baffle 32 and the rotating sleeve 12 is a fixed connection.

[0039] Working principle: The hanging ring 6 on the left side of the threaded sleeve 2 is connected to the pole through other hardware, and the hanging ring 6 on the right side of the screw rod 1 is connected to the cable through other hardware. When adjusting the connection length between the cable and the pole by rotating the screw rod 1, the personnel first rotate the rotating sleeve 12 to rotate the connecting seat 15 to a position convenient for operation, and then move the limit assembly to release the positioning of the limit assembly on the connecting seat 15;

[0040] The personnel installs the adjusting rod 33 to the upper end of the connecting seat 15 through the threaded groove 16, and then inserts a rod-shaped tool into the hanging ring 6 on the right side of the screw rod 1. Then, the personnel lifts the connecting seat 15 through the adjusting rod 33, and moves the insert 14 out from between the two adjacent tooth blocks 11. After rotating the adjusting rod 33 to a suitable position, the personnel loosens the adjusting rod 33. At this time, the insert 14 is driven by the compression force of the spring 20 to be embedded between the two adjacent tooth blocks 11. Since the hanging ring 6 on the left side of the threaded sleeve 2 is connected to the pole through a hardware fitting, the personnel When rotating the screw 1, one only needs to hold the rod-shaped tool inserted into the hanging ring 6 with one hand, and pull the adjusting rod 33 with the other hand to rotate the rotating sleeve 12 and the screw 1. When the operation of rotating the screw 1 through the adjusting rod 33 is blocked by other objects, the person can lift the block 14 up and move it out from between two adjacent tooth blocks 11, and then rotate the rotating sleeve 12 to make the block 14 embed between the other two adjacent tooth blocks 11, so that the screw 1 can be rotated continuously. The operation difficulty is relatively low, and the adjustment efficiency of the connection length between the cable and the pole can be effectively improved.

[0041] Example 2: Please refer to Figure 6-Figure 8 , this embodiment further explains the first embodiment, two symmetrically distributed hemispherical bodies 21 are fixedly embedded at the lower end of the connecting seat 15, and the limiting assembly includes an arc-shaped support plate 22 installed on the outer side of the rotating sleeve 12 and capable of rotating on the outer side of the rotating sleeve 12, and a beveled edge portion 23 is provided on the side of the arc-shaped support plate 22 close to the hemispherical body 21, and the hemispherical body 21 is in sliding contact with the arc-shaped support plate 22 through the beveled edge portion 23, and the hemispherical body 21 can reduce the friction resistance between the connecting seat 15 and the arc-shaped support plate 22, and an avoidance groove 24 is provided on the arc-shaped support plate 22, and the width of the avoidance groove 24 is greater than the diameter of the connecting rod 13, and an arc-shaped shifting plate 25 is provided on the end of the arc-shaped support plate 22 away from the hemispherical body 21, and the arc-shaped shifting plate 25 and the arc-shaped support plate 22 are an integrally formed structure.

[0042] The outer side of the arc-shaped shifting plate 25 is provided with a plurality of grooves 26 distributed at equal distances, and two symmetrically distributed arc-shaped panels 27 are fixedly installed on the outer side of the arc-shaped shifting plate 25. The outer side of the arc-shaped support plate 22 is movably abutted with two symmetrically distributed arc-shaped guide rails 28, and the connection mode between the arc-shaped guide rail 28 and the rotating sleeve 12 is a fixed connection. An arc-shaped movable groove 29 is provided on the arc-shaped guide rail 28 corresponding to the arc-shaped panel 27, and the arc-shaped panel 27 is slidably connected to the arc-shaped guide rail 28 through the arc-shaped movable groove 29. The arc-shaped panel 27 cannot rotate inside the arc-shaped guide rail 28 through the arc-shaped movable groove 29. A sealing plate 2 30 is fixedly connected to the end of the arc-shaped panel 27 away from the arc-shaped shifting plate 25, and the sealing plate 2 30 is located on the side of the arc-shaped guide rail 28 away from the arc-shaped support plate 22.

[0043] In this embodiment: before rotating the screw rod 1 to adjust the connection length between the cable and the pole, the personnel rotate the arc-shaped support plate 22 through the arc-shaped dial plate 25. During the rotation of the arc-shaped support plate 22, the hemisphere 21 at the lower end of the connecting seat 15 will slide along the hypotenuse 23 to the upper end of the arc-shaped support plate 22, so that the arc-shaped support plate 22 supports the connecting seat 15 through the hemisphere 21, so that the insert block 14 is moved out from between two adjacent tooth blocks 11, which is conducive to the arbitrary rotation of the rotating sleeve 12, thereby facilitating the personnel to rotate the connecting seat 15 to a position convenient for operation to install the adjusting rod 33.

[0044] Example 3: Please refer to Figure 7 , Figure 8 This embodiment further explains the second embodiment. Two flexible pads 31 are fixedly embedded inside the arc guide rail 28, and the two flexible pads 31 are respectively located on both sides of the arc panel 27. The connection between the arc panel 27 and the flexible pads 31 is a sliding contact. The flexible pads 31 can increase the friction resistance between the arc guide rail 28 and the arc panel 27. The flexible pads 31 are located at one end of the arc movable groove 29 away from the arc support plate 22.

[0045] In this embodiment: after the arc support plate 22 is moved away from the hemispherical body 21, the arc panel 27 is moved to the flexible pad 31. Since the width of the arc movable groove 29 where the flexible pad 31 is installed becomes smaller, the arc panel 27 will be stuck in the arc movable groove 29 through the flexible pad 31, so that the arc support plate 22 can be positioned, which can effectively prevent the arc support plate 22 from rotating and getting stuck between the hemispherical body 21 and the rotating sleeve 12 when the person lifts the connecting seat 15 and rotates the rotating sleeve 12, resulting in the inlay block 14 being unable to be embedded between the two adjacent tooth blocks 11.
