Description

Technical Field

[0001] The invention relates to the technical field of cable suspension equipment, and in particular to a suspended grating cable clamp and an installation method thereof. Background Art

[0002] After the high-voltage cable is installed, if it is stretched due to the influence of the external environment, it will have a great impact on the safety of power supply. In order to ensure the safety of power supply, it is necessary to install hanging monitoring equipment on the cable to monitor the stretching amount of the cable in real time.

[0003] At present, the commonly used monitoring method is to connect the grating and the cable in parallel through two sets of clamps. When the cable is stretched, the grating will also be stretched, so that the changes in the cable can be monitored by detecting the changes in the grating. However, due to the material, the grating is prone to breakage and cannot be twisted, but in the natural environment, the cable will inevitably twist. If it is transmitted to the grating through the clamp, it will inevitably cause the grating to twist, and then damage or even destroy the grating. In other words, based on the existing conventional clamps, it is difficult to ensure that the grating can perform the monitoring function for a long time and effectively. Summary of the invention

[0004] The purpose of the present invention is to provide a suspended grating cable clamp and an installation method thereof in view of the existing technical status. When the cable is twisted, the cable can rotate relative to the first clamping part and / or the second clamping part without causing the grating to twist, thereby avoiding damage or even destruction of the grating due to twisting.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] See also Figure 1 to Figure 6 As shown, a suspended grating cable clamp includes a first clamping portion and a second clamping portion. The specific structures of the first clamping portion and the second clamping portion are as follows:

[0038] The first clamping part includes a first suspension block 1, a first clamping plate 2 and a first bearing 12. The top surface of the first suspension block 1 is provided with a first V-shaped groove 101 penetrating the left and right sides thereof. The right side surface of the first suspension block 1 is provided with a grating mounting frame 3. The first clamping plate 2 is detachably fixed to the top surface of the first suspension block 1. The first bearing 12 is used to be sleeved and fixed on the cable 8, and it can be clamped between the first V-shaped groove 101 provided on the top surface of the first suspension block 1 and the first clamping plate 2.

[0039] The second clamping part includes a second suspension block 4, a second clamping plate 5 and a second bearing 10. The top surface of the second suspension block 4 is provided with a second V-shaped groove 401 running through its left and right side surfaces. The left side surface of the second suspension block 4 is provided with a grating mounting frame 3. The second clamping plate 5 can be detachably fixed on the top surface of the second suspension block 4. The second bearing 10 is used to be sleeved and fixed on the cable 8, and it can be clamped between the second V-shaped groove 401 provided on the top surface of the second suspension block 4 and the second clamping plate 5.

[0040] Preferably, the lower surface of the first clamping plate 2 is provided with a first arc groove 201 matched with the outer ring of the first bearing 12 , and the lower surface of the second clamping plate 5 is provided with a second arc groove 501 matched with the outer ring of the second bearing 10 .

[0041] When the first bearing 12 is clamped between the first V-shaped groove 101 provided on the top surface of the first suspension block 1 and the first clamping plate 2, the contact area between the first bearing 12 and the first arc groove 201 is larger, so that the first bearing 12 can be prevented from rotating between the first V-shaped groove 101 provided on the top surface of the first suspension block 1 and the first clamping plate 2. Similarly, when the second bearing 10 is clamped between the second V-shaped groove 401 provided on the top surface of the second suspension block 4 and the second clamping plate 5, the contact area between the second bearing 10 and the second arc groove 501 is larger, so that the second bearing 10 can be prevented from rotating between the second V-shaped groove 401 provided on the top surface of the second suspension block 4 and the second clamping plate 5.

[0042] It is further preferred that the two inclined surfaces of the first V-shaped groove 101 provided on the top surface of the first suspension block 1 and the bottom surface of the first clamping plate 2 as well as the two inclined surfaces of the second V-shaped groove 401 provided on the top surface of the second suspension block 4 and the bottom surface of the second clamping plate 5 are all provided with anti-slip pads (not shown in the figure).

[0043] By adding anti-slip pads, the effect of preventing the first bearing 12 from rotating between the first V-groove 101 provided on the top surface of the first suspension block 1 and the first clamping plate 2 and preventing the second bearing 10 from rotating between the second V-groove 401 provided on the top surface of the second suspension block 4 and the second clamping plate 5 can be strengthened.

[0044] Illustratively, in this embodiment, the first clamping plate 2 is detachably fixed to the top surface of the first suspension block 1 by bolts, and the second clamping plate 5 is also detachably fixed to the top surface of the second suspension block 4 by bolts.

[0045] According to the above technical solution, the grating 9 can be installed on the cable 8 in parallel through the first clamping part and the second clamping part, and at the same time, the cable 8 can rotate relative to the first clamping part and the second clamping part based on the first bearing 12 and the second bearing 10. Due to the effect of gravity, the grating 9 will be suspended under the cable 8.

[0046] See also Figure 8 , Fig. 9 As shown, as another embodiment, based on the above technical solution, a bird-repelling mechanism is provided on the bottom surface of the second suspension block 4, and the bird-repelling mechanism includes a bracket 6 and a wind cup 7, the bracket 6 is rotatably connected to the second suspension block 4, and the wind cup 7 is fixed on the bracket 6.

[0047] After the grating 9 is installed on the cable 8 in parallel through the first clamping part and the second clamping part, the wind cup 7 will rotate on the bracket 6 under the action of wind. The change of rotation posture can drive away birds and prevent birds from stopping on the grating 9 and causing damage or even destruction to the grating 9.

[0048] Preferably, a monitor 13 and a battery are provided in the second suspension block 4 , a monitoring port of the monitor 13 is arranged on a side of the second suspension block 4 where the grating mounting frame 3 is provided, and the battery is electrically connected to the monitor 13 .

[0049] The grating 9 installed on the cable 8 is observed and monitored by the monitor 13, providing information to the ground personnel to facilitate maintenance work.

[0050] Further preferably, a generator is further provided in the second suspension block 4, a driving end of the generator is connected to the bracket 6 of the bird-repelling mechanism, and a battery is electrically connected to the generator.

[0051] The birds can be driven away by the rotation posture change of the bird-repelling mechanism, and the energy can also be converted into electrical energy by a generator for use by a battery supporting the monitor 13 to improve the endurance of the monitor 13.

[0052] Exemplarily, in this embodiment, three wind cups 7 are evenly fixed on the bracket 6 of the bird-repelling mechanism.

[0053] See also Figure 1 to Figure 6 As shown, a method for installing a suspended grating cable clamp is applied to the above-mentioned suspended grating cable clamp, comprising the following steps:

[0054] S1, sleeve the first bearing 12 and the second bearing 10 on the cable 8, move them to a predetermined position, and then fix the first bearing 12 and the second bearing 10 to the cable 8;

[0055] S2, placing the first bearing 12 in the first V-shaped groove 101 provided on the first suspension block 1, and then fixing the first clamping plate 2 to the top surface of the first suspension block 1, so that the first bearing 12 is clamped;

[0056] The second bearing 10 is placed in the second V-shaped groove 401 provided on the second suspension block 4, and then the second clamping plate 5 is fixed to the top surface of the second suspension block 4, so that the second bearing 10 is clamped;

[0057] S3, connecting the grating 9 between the grating mounting frame 3 provided on the first suspension block 1 and the grating mounting frame 3 provided on the second suspension block 4. At least two gratings 9 are connected between the grating mounting frame 3 provided on the first suspension block 1 and the grating mounting frame 3 provided on the second suspension block 4, and the detection values ​​of the multiple gratings 9 are mutually verified or averaged to improve the reliability of the detection data.

[0058] Specifically, in step S1, the steps of fixing the first bearing 12 and the second bearing 10 to the cable 8 are as follows:

[0059] A fixing pin 11 is inserted between the first bearing 12 and the cable 8 so that an interference fit is formed between the inner ring of the first bearing 12 and the cable 8;

[0060] A fixing pin 11 is inserted between the second bearing 10 and the cable 8 , so that an interference fit is formed between the inner ring of the second bearing 10 and the cable 8 .

[0061] Since the fixing pin 11 is relatively close to the cable 8, the operation surface for inserting the fixing pin 11 between the first bearing 12 and the cable 8 or between the second bearing 10 and the cable 8 is small, and the operation is relatively difficult. Therefore, the fixing pin 11 is designed as an L-shaped structure, which increases the operation surface and makes the operation easier.

[0062] Exemplarily, in this embodiment, two fixing pins 11 are symmetrically inserted between the first bearing 12 and the cable 8; two fixing pins 11 are symmetrically inserted between the second bearing 10 and the cable 8; and three gratings 9 are connected between the grating mounting frame 3 provided on the first suspension block 1 and the grating mounting frame 3 provided on the second suspension block 4.

[0063] In general, the present invention can install the grating 9 on the cable 8 in parallel through the first clamping part and the second clamping part, and at the same time, based on the first bearing 12 and the second bearing 10, the cable 8 can rotate relative to the first clamping part and the second clamping part. According to the above design, when the cable 8 is stretched, the grating 9 will be stretched, and then the stretch change of the cable 8 will be detected, and when the cable 8 is twisted, the cable 8 can rotate relative to the first clamping part and / or the second clamping part, and the grating 9 will not be twisted, thereby avoiding damage or even destruction of the grating 9 due to twisting.

[0064] The present invention is not limited to the above-mentioned specific implementation modes. A person skilled in the art can implement the present invention in various other specific implementation modes based on the contents disclosed in the present invention. Therefore, any design that adopts the design structure and concept of the present invention and makes some simple changes or modifications shall fall within the scope of protection of the present invention.
