Description

Technical Field

[0001] This utility model relates to the field of tension clamp technology, specifically a hydraulic tension clamp connecting fitting. Background Technology

[0002] Hydraulic tension clamps are a key electrical connection component in high-voltage overhead transmission lines, serving as a conductor transition and current shunting mechanism. Based on their structure and installation conditions, tension clamps can be broadly classified into two categories. The first category: These tension clamps must withstand the entire tension of the conductor or lightning protection wire. The clamp's gripping force must not be less than the rated tensile strength of the installed conductor or lightning protection wire. These clamps can be removed and reused after the conductor is installed. This type includes bolt-type tension clamps and wedge-type tension clamps. The second category: In addition to bearing the entire tension of the conductor or lightning protection wire, these tension clamps also act as conductors. Because they are conductors, their installation must be carried out strictly in accordance with relevant installation and operation procedures.

[0003] Existing hydraulic tension clamp connectors are not convenient for adjusting the installation height according to different environments, which can cause the device to be suspended in mid-air during installation, resulting in low safety. Furthermore, existing hydraulic tension clamp connectors are not convenient for fixing cables of different diameters, which can lead to cables coming loose, making them impractical.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a hydraulic tension clamp connecting hardware, including a mounting frame 1, a mounting hole 2 on one side of the mounting frame 1, a lifting groove 3 inside the mounting frame 1, a lifting column 4 slidably connected inside the lifting groove 3, a sliding groove 5 on one side of the lifting column 4, a first lead screw 6 rotatably connected inside the sliding groove 5, a sliding seat 7 being drivenly connected to the outside of the first lead screw 6, the outside of the sliding seat 7 being slidably connected inside the sliding groove 5, a rotating seat 8 being fixedly installed at one end of the first lead screw 6, a sliding ring 9 being fixedly installed on the outside of the sliding seat 7, and the inside of the sliding ring 9 being slidably connected to the outside of the lifting column 4.

[0024] Specifically, turning the rotating seat 8 will cause the first lead screw 6 to rotate, which in turn will cause the sliding seat 7 to move, making the sliding seat 7 slide inside the sliding groove 5. The sliding seat 7 will then cause the sliding ring 9 to move, making the sliding ring 9 slide outside the lifting column 4.

[0025] Please see Figures 3 to 4 A connecting seat 10 is fixedly installed on one side of the sliding ring 9, and a limit post 11 is fixedly installed on one end of the connecting seat 10.

[0026] Specifically, the sliding ring 9 will drive the connecting seat 10 to move, and the connecting seat 10 will drive the limiting post 11 to move.

[0027] Please see Figures 3 to 4 A limiting hole 12 is provided on one side of the mounting bracket 1, and one end of the limiting post 11 is inserted into the limiting hole 12. A wire clamp body 13 is fixedly installed on one end of the lifting post 4.

[0028] Specifically, the connecting seat 10 will drive the limiting post 11 to move, so that one end of the limiting post 11 is disengaged from the inside of the limiting hole 12, and the size of the limiting post 11 is adapted to the size of the limiting hole 12.

[0029] Please see Figures 3 to 4 The wire clamp body 13 has a wire groove 14 inside, and a lifting and moving groove 15 is provided on the inner side wall of the wire groove 14. A second lead screw 16 is rotatably connected inside the lifting and moving groove 15.

[0030] Specifically, the cable is first placed inside the cable tray 14, and the second lead screw 16 rotates inside the lifting and moving tray 15.

[0031] Please see Figures 3 to 4 A knob 17 is fixedly installed at one end of the second lead screw 16, and a lifting moving seat 18 is driven to the outside of the second lead screw 16. The outside of the lifting moving seat 18 is slidably connected to the inside of the lifting moving groove 15.

[0032] Specifically, turning the knob 17 will cause the second lead screw 16 to rotate, which in turn will cause the lifting moving seat 18 to move downward inside the lifting moving groove 15.

[0033] Please see Figures 3 to 4 A clamping seat 19 is fixedly installed at one end of the lifting and moving seat 18, and a clamping ring 20 is fixedly installed at the bottom of the clamping seat 19.

[0034] Specifically, the lifting and moving seat 18 will drive the pressing seat 19 to move downward, and the pressing seat 19 will drive the pressing ring 20 to move downward, so that the pressing ring 20 presses the cable.

[0035] In use, first place the cable inside the cable tray 14, then turn the knob 17. The knob 17 will drive the second lead screw 16 to rotate, which in turn will drive the lifting moving seat 18 to move downwards inside the lifting moving groove 15. The lifting moving seat 18 will then drive the clamping seat 19 to move downwards, which in turn will drive the clamping ring 20 to move downwards, thus clamping the cable. When the installation height needs to be adjusted, turn the rotating seat 8. The rotating seat 8 will drive the first lead screw 6 to rotate, which in turn will drive the sliding seat 7 to move, causing the sliding seat 7 to slide inside the sliding groove 5. 7 will drive the sliding ring 9 to move, causing the sliding ring 9 to slide on the outside of the lifting column 4. The sliding ring 9 will drive the connecting seat 10 to move, and the connecting seat 10 will drive the limiting column 11 to move, causing one end of the limiting column 11 to disengage from the inside of the limiting hole 12. At this time, the mounting frame 1 is moved up or down, and the mounting frame 1 will slide on the outside of the lifting column 4 through the lifting groove 3, so that the mounting frame 1 is adjusted to a suitable position. After the adjustment is completed, the rotating seat 8 is rotated in the opposite direction, so that one end of the limiting column 11 is inserted into the inside of the limiting hole 12, thereby limiting the lifting column 4. Then, the entire device is installed in a suitable position through the mounting hole 2 opened in the mounting frame 1.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
