Description

Technical Field

[0001] The utility model relates to the technical field of electric power accessories, in particular to a damping spacer. Background Technique

[0002] A spacer refers to a fitting installed on a bundled conductor to fix the distance between each bundled conductor to prevent the conductors from whipping each other, suppress aeolian vibration and sub-span oscillation. Generally, the spacer is installed in the middle of the span and is divided into spacers for two-conductor, four-conductor, six-conductor, and eight-conductor bundles.

[0003] Spacers can be divided into two categories: damping and rigid from the perspective of performance. The damping type spacer has wear-resistant rubber pads embedded in its moving parts, and the damping of the rubber pads is used to consume the vibration energy of the conductor, thereby producing a damping effect on the conductor vibration. Those without such rubber pads are rigid spacers, which are generally used in areas where vibration is not likely to occur or for jumper spacers due to their poor vibration damping performance.

[0004] For the common damping spacers on the current market, their spacing is generally fixed and cannot be adjusted appropriately after installation, resulting in great limitations in the spacing of the spacers. Therefore, we propose a damping spacer. Content of the Utility Model

[0005] The purpose of the utility model is to provide a damping spacer to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A damping spacer, including a bracket 1, both ends of the bracket 1 are movably installed with a first shaft bracket 2 and a second shaft bracket 3, and a rod sleeve 4 is movably installed inside both the first shaft bracket 2 and the second shaft bracket 3 through a rotating shaft;

[0008] On the outer side of each rod sleeve 4 away from the bracket 2, a connecting piece 5 is installed, the other end of the connecting piece 5 is fixedly connected with an upper clamping sleeve 6, a lower clamping sleeve 7 is installed below the upper clamping sleeve 6 through bolts, and damping inner pads 8 are arranged on the inner walls of both the upper clamping sleeve 6 and the lower clamping sleeve 7;

[0009] A transverse threaded rod 9 is arranged in the middle of the bracket 1, both ends of the threaded rod 9 are threadedly sleeved with movable sleeves 10, and a fixed bracket 11 is fixedly installed at one end of each movable sleeve 10 away from each other;

[0010] Both ends of the first shaft bracket 2 and the second shaft bracket 3 close to one side of the bracket 1 are fixedly connected with sliding members 12, and the sliding members 12 are fixedly connected with the fixed brackets 11.

[0011] Through the above technical solution, by setting the threaded rod 9 and the movable sleeve 10, when it is necessary to adjust the spacing between the cables at both ends of the bracket 1, the threaded rod 9 is rotated. After the threaded rod 9 is rotated, the movable sleeves 10 at both ends are driven to move linearly outward. When the movable sleeves 10 at both ends move at the same time, the first axis frame 2 and the second axis frame 3 are driven to move respectively through the fixed frame 11. When the first axis frame 2 and the second axis frame 3 move, they drive the upper jacket 6 and the lower jacket 7 to push the clamped cables outward, so that the spacing between the cables can be conveniently adjusted.

[0012] Furthermore, a toggle block 14 is fixedly sleeved in the middle of the threaded rod 9 .

[0013] According to the above technical solution, by arranging the toggle block 14 on the outer side of the middle part of the threaded rod 9, it is convenient to use a tool to rotate the toggle block 14, thereby driving the threaded rod 9 to rotate.

[0014] Furthermore, the thread directions of the two ends of the threaded rod 9 are opposite.

[0015] Through the above technical solution, by setting the thread directions of the two ends of the threaded rod 9 to opposite directions, it is convenient to control the two movable sleeves 10 to move in opposite directions, thereby facilitating the adjustment of the spacing.

[0016] Furthermore, a fixing member 13 is provided at intervals inside the bracket 2, and the fixing member 13 is rotatably connected to the threaded rod 9 via a bearing.

[0017] Through the above technical solution, the fixing member 13 plays a role in installing and supporting the threaded rod 9.

[0018] Furthermore, both ends of the bracket 1 are provided with a slide groove 15 , and one end of the sliding member 12 close to the slide groove 15 is provided with a slide rod 16 matching the slide groove 15 , and the slide rod 16 is slidably connected to the slide groove 15 .

[0019] Through the above technical solution, by setting the sliding groove 15 and the sliding rod 16, when the first axis frame 2 and the second axis frame 3 move, the sliding members 12 at both ends of the first axis frame 2 and the second axis frame 3 close to the bracket 1 will drive the sliding rod 16 to slide synchronously along the sliding groove 15 at both ends of the bracket 1, so that the first axis frame 2 and the second axis frame 3 can be kept moving in a straight line and will not be separated from the bracket 1, thereby achieving the purpose of facilitating active connection.

[0020] Furthermore, an outer end of the sliding rod 16 close to the bracket 1 is threadedly connected with an anti-drop nut 17 .

[0021] According to the above technical solution, by providing the anti-dropping nut 17 on the outer side of the slide rod 16 , the slide rod 16 can be prevented from slipping out of the slide groove 15 .

[0022] Furthermore, a plurality of anti-slip grooves 18 are formed on the inner surface of the damping inner pad 8 .

[0023] Through the above technical solution, by providing the anti-skid groove 18, an anti-skid effect can be achieved when clamping the cable.

[0024] Compared with the prior art, the damping spacer rod of the utility model has the following beneficial effects:

[0025] (1) By setting a threaded rod and a movable sleeve, when it is necessary to adjust the spacing of the cables at both ends of the bracket, a tool is used to twist the toggle block. When the toggle block rotates, it drives the threaded rod to rotate synchronously. After the threaded rod rotates, it drives the movable sleeves at both ends to move linearly outward at the same time. When the movable sleeves at both ends move at the same time, the first axis frame and the second axis frame are driven to move respectively through the fixed frame. When the first axis frame and the second axis frame move, they drive the upper clamping sleeve and the lower clamping sleeve to push the clamped cables outward. In this way, the spacing of the cables can be easily adjusted, which solves the problem that the spacing distance of the spacer bars in the prior art is very limited.

[0026] (2) By setting the sliding groove and the sliding rod, when the first axis frame and the second axis frame move, the sliding members at both ends of the first axis frame and the second axis frame close to one side of the bracket will drive the sliding rod to slide synchronously along the sliding grooves at both ends of the bracket, so that the first axis frame and the second axis frame can be kept moving in a straight line and will not be separated from the bracket, thereby achieving the purpose of facilitating active connection.

[0036] Example 1

[0037] like Figures 1-4 As shown, the utility model proposes a damping spacer rod, comprising a bracket 1, wherein a first axis frame 2 and a second axis frame 3 are movably mounted at both ends of the bracket 1, and a rod sleeve 4 is movably mounted inside the first axis frame 2 and the second axis frame 3 through a rotating shaft; a connecting member 5 is mounted on the outside of each rod sleeve 4 away from the bracket 2, and an upper jacket 6 is fixedly connected to the other end of the connecting member 5, and a lower jacket 7 is mounted below the upper jacket 6 through bolts, and damping inner pads 8 are provided on the inner walls of the upper jacket 6 and the lower jacket 7, and a plurality of anti-slip grooves 18 are provided on the inner surface of the damping inner pad 8, and the anti-slip grooves 18 can be provided to prevent slipping when clamping cables.

[0038] A transverse threaded rod 9 is provided in the middle of the bracket 1, and a toggle block 14 is fixedly sleeved in the middle of the threaded rod 9. The thread directions of the two ends of the threaded rod 9 are opposite, and both ends of the threaded rod 9 are threadedly sleeved with movable sleeves 10, and each end of the movable sleeve 10 away from each other is fixedly installed with a fixing 11; the first axis frame 2 and the second axis frame 3 are fixedly connected with sliding members 12 at both ends of the side close to the bracket 1, and the sliding member 12 is fixedly connected to the fixed frame 11.

[0039] During specific implementation, when it is necessary to adjust the spacing between the cables at both ends of the bracket 1, a tool is used to twist the toggle block 14. When the toggle block 14 rotates, it drives the threaded rod 9 to rotate synchronously. After the threaded rod 9 rotates, it drives the movable sleeves 10 at both ends to move outward in a straight line. When the movable sleeves 10 at both ends move at the same time, the first axis frame 2 and the second axis frame 3 are driven to move respectively through the fixed frame 11. When the first axis frame 2 and the second axis frame 3 move, they drive the upper jacket 6 and the lower jacket 7 to push the clamped cables outward, so that the spacing between the cables can be easily adjusted.

[0040] The bracket 2 is provided with a fixing piece 13 at intervals inside. The fixing piece 13 is rotatably connected to the threaded rod 9 via a bearing. In the utility model, the fixing piece 13 plays a role of installing and supporting the threaded rod 9 .

[0041] Slide grooves 15 are provided at both ends of the bracket 1, and a slide rod 16 matching the slide groove 15 is provided at one end of the sliding member 12 close to the slide groove 15. The slide rod 16 is slidably connected to the slide groove 15, and an anti-slip nut 17 is threadedly connected to one end of the slide rod 16 close to the outer side of the bracket 1.

[0042] In specific implementation, by setting the slide groove 15 and the slide rod 16, when the first axis frame 2 and the second axis frame 3 move, the sliding members 12 at both ends of the first axis frame 2 and the second axis frame 3 close to the bracket 1 will drive the slide rod 16 to slide synchronously along the slide groove 15 at both ends of the bracket 1, so that the first axis frame 2 and the second axis frame 3 can be kept moving linearly and will not be separated from the bracket 1, thereby achieving the purpose of facilitating active connection. By setting the anti-slip nut 17 on the outside of the slide rod 16, the slide rod 16 can be prevented from slipping out of the slide groove 15.

[0043] When the damping spacer of the present invention is in use, the cables are fixedly clamped by the upper jacket 6 and the lower jacket 7 at the two ends of the bracket 1. The damping inner pads 8 arranged inside the upper jacket 6 and the lower jacket 7 can effectively prevent the cables from whipping each other, suppress breeze vibration and sub-spacing oscillation. At the same time, the anti-skid grooves 18 arranged on the surface of the damping inner pads 8 can achieve the purpose of anti-skid when clamping. When it is necessary to adjust the spacing between the cables at both ends of the bracket 1, a tool is used to twist the toggle block 14. When the toggle block 14 rotates, it drives the threaded rod 9 to rotate synchronously. After the threaded rod 9 rotates, it drives the movable sleeves 10 at both ends to move outward in a straight line. When the movable sleeves 10 at both ends move at the same time, the first axis frame 2 and the second axis frame 3 are respectively driven to move through the fixed frame 11. When the first axis frame 2 and the second axis frame 3 move, they drive the upper jacket 6 and the lower jacket 7 to push the clamped cables outward, so that the spacing between the cables can be conveniently adjusted.
