Description

Technical Field

[0001] The invention relates to the technical field of clamps, and in particular to a high-altitude cable fixing clamp with a vibration suppression function. Background Art

[0002] Aerial cable installation involves securing cables securely to elevated structures such as power towers, communication towers or bridges. The clamps used in the installation are mainly used to secure and support the cables to ensure their stable operation in high-altitude environments.

[0003] The existing high-altitude cable installation clamps are relatively simple, mostly arranged along both sides of the cable through two annular clamp plates, and then the two clamp plates are brought close together by bolts to hold the cable tightly and fix it. Special screw-tightening tools are required during installation or removal. The wind is strong at high altitudes, and the installation is more troublesome and time-consuming. There is a risk that the nuts on the bolts may loosen and fall off, and the stability is poor. In addition, it does not have a vibration suppression effect. Due to the influence of strong wind at high altitudes, the cable and the clamp will be forced to vibrate, and the large vibration energy will affect the safety of the cable and the clamp. For this reason, we propose a high-altitude cable fixing clamp with vibration suppression function. Summary of the invention

[0004] The object of the present invention is to provide a high-altitude cable fixing clamp with a vibration suppression function to solve the problem that when installing the existing high-altitude cables proposed in the above-mentioned background technology, two clamp plates need to be connected and fixed by bolts, and installation and disassembly require special screw-tightening tools, which are troublesome to operate, and there is a risk of nuts on the bolts falling off, and the stability is poor after installation.

[0005] To achieve the above object, the present invention provides the following technical solution: a high-altitude cable fixing clamp with vibration suppression function, comprising:

[0006] Base;

[0007] A rotating support assembly is rotatably mounted on the base;

[0008] A first limiting plate is arranged on the rotating support assembly to cooperate with the base to fix the cable, and a limiting hook is provided on the lower surface of the first limiting plate;

[0009] A second limiting plate is arranged side by side with the first limiting plate, and a telescopic rod is provided between the first limiting plate and the second limiting plate;

[0010] A spring is sleeved on the outer surface of the telescopic rod to pull the first limit plate and the second limit plate closer together, so that the limit hook is matched with the rotating column of a side wall of the rotating support assembly;

[0011] The anti-vibration component is arranged between the first limiting plate and the second limiting plate to suppress the vibration of the high-altitude cable, and the anti-vibration component is staggered with the telescopic rod.

[0012] Preferably, the anti-vibration assembly includes a connecting plate, a stranded wire, a weight and a return spring. The connecting plate is detachably arranged on the second limiting plate. A stranded wire is slidably arranged on the inner side of the connecting plate. A return spring is sleeved on one end of the stranded wire, and one end of the return spring is in contact with the connecting plate. A weight is fixed to the other end of the stranded wire.

[0014] Preferably, a third limiting plate is fixed to the middle of the upper surface of the base, and two ends of the third limiting plate correspond to the first limiting plate and the second limiting plate respectively.

[0015] Preferably, the rotating support assembly includes a ring block, a support block, a clamping block and a limit spring. A mounting groove is provided on the base, and a rotating rod is fixed to the inner side of the mounting groove. The ring block is rotatably sleeved on the rotating rod. A support block is fixed to one side wall of the ring block, and the support block is fixed to the rotating column. The clamping block is slidably installed on the inner lower end of the base, and a limit spring is provided on the lower surface of the clamping block.

[0020] Preferably, grooves connected to the external bracket are formed along the long sides of the front and rear surfaces of the base.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) By providing a base, a rotating support assembly, a first limit plate, a second limit plate, a telescopic rod, a spring and a limit hook, it is avoided that when the cable clamp is installed, a special screw-tightening tool is needed to tighten the nut so that the clamp is tightly fixed to the cable. The device does not require special tools to clamp the cable tightly, thereby improving the convenience of installation. By reducing the use of nuts, the risk of the nuts loosening and falling off in the later stage is avoided, thereby improving the stability of the fixation.

[0023] (2) By providing a twisted wire, a weight and a return spring, the cable can be prevented from vibrating greatly due to the influence of wind at high altitudes. The device can consume vibration energy through the up and down swing of the weight and the elastic expansion and contraction of the return spring, thereby reducing the impact of vibration on the cable, improving the safety of the cable and ensuring the use effect.

[0038] The spring 9 is sleeved on the outer surface of the telescopic rod 8 to pull the first limit plate 3 and the second limit plate 4 closer together, so that the limit hook 10 cooperates with the rotating column 7 on one side wall of the rotating support assembly 2, so as to facilitate pulling the limit hook 10 and the rotating column 7 to be close to each other so as to quickly make the first limit plate 3 and the second limit plate 4 hold the cable tightly;

[0039] The anti-vibration component 5 is arranged between the first limiting plate 3 and the second limiting plate 4 to suppress the vibration of the high-altitude cable, and the anti-vibration component 5 is staggered with the telescopic rod 8 to facilitate the energy dissipation of the vibration in the air, thereby reducing the damage of the vibration energy to the cable.

[0040] Preferably, the anti-vibration component 5 includes a connecting plate 501, a stranded wire 502, a weight 503 and a return spring 504. The connecting plate 501 is detachably arranged on the second limiting plate 4. The stranded wire 502 is slidably arranged on the inner side of the connecting plate 501.

One end of the return spring 504 is in contact with the connecting plate 501, which is convenient for consuming vibration energy through elastic potential energy. A weight 503 is fixed to the other end of the stranded wire 502, which is convenient for converting vibration energy into kinetic energy, thereby consuming vibration energy.

[0041] Preferably, the stranded wires 502 are symmetrically arranged at four locations along the weight 503 , and the stranded wires 502 are of an inclined structure, so as to facilitate the arrangement of a greater length of the stranded wires 502 .

[0042] Preferably, a third limiting plate 101 is fixed to the middle of the upper surface of the base 1, and two ends of the third limiting plate 101 correspond to the first limiting plate 3 and the second limiting plate 4 respectively, so as to facilitate the cable to be clamped and fixed.

[0043] Preferably, the rotating support assembly 2 includes a ring block 201, a support block 202, a clamping block 204 and a limiting spring 205. A mounting groove 103 is provided on the base 1, and a rotating rod 104 is fixed to the inner side of the mounting groove 103. The ring block 201 is rotatably sleeved on the rotating rod 104. A support block 202 is fixed to one side wall of the ring block 201, and the support block 202 is fixed to the rotating column 7, so as to support the first limiting plate 3 and the second limiting plate 4. The distance between the first limiting plate 3, the second limiting plate 4 and the third limiting plate 101 can be adjusted according to the outer diameter of the actual cable. The clamping block 204 is slidably installed at the lower end of the inner side of the base 1, and a limiting spring 205 is provided on the lower surface of the clamping block 204. The outer surface of the ring block 201 is provided with oblique tooth grooves matching the clamping block 204 along its circumference, so as to lock its position after the support block 202 is rotated and adjusted.

[0044] Preferably, the rotating support assembly 2 further includes a pressure rod 206 and a pressing handle 207. The side wall of the block 204 is provided with a pressure rod 206, and the top of the pressure rod 206 has a pressing handle 207 to facilitate the block 204 to withdraw from the inner side of the oblique tooth groove.

[0045] Preferably, four ring blocks 201 and four support blocks 202 are provided, and the rotating columns 7 between every two adjacent support blocks 202 are staggered to facilitate better cooperation with the limiting hooks 10 .

[0046] Preferably, the lower surface of the second limiting plate 4 is connected to a pressing plate 6 via an elastic member, and the pressing plate 6 is arc-shaped, so as to better hold the cable through the elastic member.

[0048] Preferably, grooves connected to the external bracket are formed on the front and rear surfaces of the base 1 along its long sides.

[0049] The working principle and use process of the present invention are as follows: when installed outdoors at high altitude, the base 1 is fixed to the mounting frame, and then the cable is placed on the third limiting plate 101, and the first limiting plate 3 and the second limiting plate 4 are pulled away from each other. At this time, the telescopic rod 8 is extended, and the pressing plate 6 on the lower surface of the first limiting plate 3 and the second limiting plate 4 is pressed against the cable, and the four limiting hooks 10 on the lower surface of the first limiting plate 3 and the second limiting plate 4 are respectively matched with the rotating column 7, and continue to press against and press against one side of the cable. At this time, the support blocks 202 and 104 are spaced apart. By rotating the ring block 201, the clamping block 204 enters the inner side of another oblique tooth groove from one oblique tooth groove on the outer surface of the ring block 201 until the third limiting plate 101, the first limiting plate 3 and the second limiting plate 4 hold the cable tightly, so that the position of the support block 202 can be self-locked to complete the fixation of the cable. When it is necessary to release the lock in the later stage, it is only necessary to press the pressure rod 206 downward through the pressing handle 207 to disengage the clamping block 204 from the inner side of the oblique tooth groove, and the ring block 201 can rotate freely, thereby releasing the second limiting plate 4 and the first limiting plate 3 from limiting the cable.
