Description

Technical Field

[0001] The present application relates to the technical field of power transmission line operation and maintenance, and in particular to an installation device for a suspension wire clamp. Background Art

[0002] The suspension wire clamp is a device used to fix the conductor on the straight pole tower. The suspension wire clamp includes a wire clamp hull and a U-bolt. When in use, the conductor is placed in the wire clamp hull, and the U-bolt is assembled with the wire clamp hull to tightly grip the conductor between the wire clamp hull and the U-bolt, thereby fixing the conductor. When the suspension wire clamp is assembled, the gripping force between the wire clamp hull and the U-bolt will affect the fixing effect of the conductor. If the gripping force between the wire clamp hull and the U-bolt is too large, the suspension wire clamp will cause the ground wire bracket to deform when it jumps due to uneven ice covering and de-icing in winter. If the gripping force between the wire clamp hull and the U-bolt is too small, the suspension wire clamp is prone to slippage, resulting in deformation of the pre-twisted wire, affecting the safe operation of the transmission line.

[0035] Please refer to Figures 1 to 3. The suspension wire clamp 10 is composed of a wire clamp hull 11, a U-shaped bolt 12 and a mounting nut 13. The wire clamp hull 11 is provided with a receiving groove 14. Both ends of the U-shaped bolt 12 are bent and provided with external threads. When in use, the wire is placed in the receiving groove 14 of the wire clamp hull 11, and both ends of the U-shaped bolt 12 are passed through the two sides of the wire clamp hull 11. The mounting nut 13 is screwed with the external threads at both ends of the U-shaped bolt 12 to hold the wire tightly between the receiving groove 14 of the wire clamp hull 11 and the U-shaped bolt 12.

[0036] In the conventional technology, the threaded connection between the mounting nut 13 and the external thread of the U-bolt 12 is mainly tightened manually by the staff using a wrench. There are large operating errors in this process, which may cause the gripping force between the wire clamp hull 11 and the U-bolt 12 to be too large or too small, thereby affecting the safe operation of the transmission line.

[0037] Please refer to Figure 3. An embodiment of the present application provides an installation device for a suspension wire clamp 10, including a torque output member 100, a torque sensor 200 and a nut sleeve 300. The torque output member 100 is provided with a rotatable torque output portion 110; one end of the torque sensor 200 is provided with a first connecting portion 210, the first connecting portion 210 is assembled with the torque output portion 110, and the other end of the torque sensor 200 is provided with a second connecting portion 220; one end of the nut sleeve 300 is assembled with the second connecting portion 220, and the other end of the nut sleeve 300 is provided with a receiving groove 310, and the receiving groove 310 is used to be assembled with the mounting nut 13 of the suspension wire clamp 10.

[0038] In the above-mentioned installation device for the suspension wire clamp 10, the torque output by the torque output part 110 is transmitted to the torque sensor 200 through the first connection part 210, and the torque is then transmitted to the nut sleeve 300 through the second connection part 220. The nut sleeve 300 can be assembled with the mounting nut 13 of the suspension wire clamp 10 to tighten the mounting nut 13 of the suspension wire clamp 10; during this process, the torque sensor 200 can monitor the torque it receives, thereby monitoring the torque output part 110 outputting the mounting nut 13 of the suspension wire clamp 10. The torque outputted can prevent the mounting nut 13 from being over-tightened, resulting in excessive gripping force between the clamp hull 11 and the U-bolt 12, or the mounting nut 13 from being under-tightened, resulting in excessive gripping force between the clamp hull 11 and the U-bolt 12; compared with the conventional technology, the above-mentioned mounting device for the suspension clamp 10 can ensure that the torque outputted by the torque output part 110 to the mounting nut 13 of the suspension clamp 10 is within a preset range, thereby ensuring that the gripping force between the clamp hull 11 and the U-bolt 12 is within a suitable range, thereby improving the operational safety of the transmission line.

[0039] For explanation, normally, the same wire clamp hull 11 is provided with at least two U-shaped bolts 12, and each U-shaped bolt 12 is provided with two mounting nuts 13. For example, in the embodiments shown in Figures 1 and 2, two U-shaped bolts 12 are provided and are spaced apart along the length direction of the wire clamp hull 11, and four mounting nuts 13 are provided. The gripping force of the wire clamp hull 11 and the U-shaped bolt 12 on the wire can be obtained by converting the torque of the mounting nut 13 on the U-shaped bolt 12.

[0040] Furthermore, the torque values ​​of the four mounting nuts 13 are set to be T 1 , T 2 , T 3 , T 4 , because the mounting nut 13 will generate pressure on the clamp hull 11 after being tightened, the pressures generated by the four mounting nuts 13 on the clamp hull 11 are TF 1 TF 2 TF 3and TF 4 , then T 1 =μ a *TF 1 *D, T 2 =μ a *TF 2 *D, T 3 =μ a *TF 3 *D, T 4 =μ a *TF 4 *D, for a specific type of bolt, μ a is a constant value, which can be obtained through actual test, and D is the diameter of the bolt. The gripping force FF of the wire clamp hull 11 and the U-bolt 12 on the wire is proportional to the sum of the pressures generated by the four mounting nuts 13 on the wire clamp hull 11. FF=μ b *∑(TF n ), for a particular type of clamp hull 11 and conductor, μ b It can be obtained through experimental measurement that FF = μ c (T 1 +T 2 +T 3 +T 4 ), where μ c =μ b / μ a .

[0041] Before installing the suspension clamp 10, a preset torque for installing the suspension clamp 10 is set for the installation device, and then the installation bolts of the suspension clamp 10 are tightened by the installation device. During the tightening process, if the torque measured by the torque sensor 200 reaches the preset range, an alarm is issued to the staff to remind the staff to slow down the tightening speed in time to prevent over-tightening. After the suspension clamp is installed, the predicted grip value of the torque sensor 200 is calculated based on the installation torque value to provide a reference for line inspection and maintenance.

[0042] In another embodiment, before installing the suspension wire clamp 10, a preset grip force for installing the suspension wire clamp 10 is first set for the installation device, and the preset torque range of the torque sensor is calculated based on the preset grip force. Then, the installation bolts of the suspension wire clamp 10 are tightened by the installation device. During the tightening process, if the torque measured by the torque sensor 200 is not within the preset torque range, an alarm is issued to the staff, reminding the staff to adjust the torque output to the installation bolts.

[0043] In one embodiment, the torque output member 100 may be a torque wrench; alternatively, the torque wrench may be a manual torque wrench or an electric torque wrench, which is not specifically limited herein.

[0044] Please refer to Figure 5. In one embodiment, the torque sensor 200 includes a transmission shaft 250 and a strain monitoring mechanism. A first connecting portion 210 is provided at one end of the transmission shaft 250, and a second connecting portion 220 is provided at the other end of the transmission shaft 250. The strain monitoring mechanism is provided on the transmission shaft 250 and is used to monitor the deformation of the transmission shaft 250.

[0045] The torque output part 110 of the torque output member 100 rotates, and drives the transmission shaft 250 to rotate through the first connecting part 210, and then drives the nut sleeve 300 to rotate to tighten the mounting nut 13 of the suspension wire clamp 10. During this process, the transmission shaft 250 will be subjected to the torque output by the torque output part 110 and undergo torsional deformation, and the strain monitoring mechanism can collect and monitor the torsional variables occurring in the transmission shaft 250, and convert the torsional deformation variables into the torque received by the transmission shaft 250, and then obtain the torque of the mounting nut 13; with such a configuration, the torque of the mounting nut 13 can be accurately obtained while achieving the tightening of the mounting nut 13, and then the gripping force between the wire clamp hull 11 and the U-bolt 12 can be obtained, and the process is reliable.

[0046] Please refer to Figure 5. In one embodiment, the strain monitoring mechanism includes a shell 230, a strain gauge and an electrical connection part 240. The transmission shaft 250 passes through the shell 230. The strain gauge is arranged on the transmission shaft 250 and is electrically connected to the electrical connection part 240. The electrical connection part 240 is arranged outside the shell 230 and can obtain the deformation amount of the strain gauge. The electrical connection part 240 is used to be electrically connected to the data acquisition device.

[0047] The strain gauge is arranged on the transmission shaft 250. When the transmission shaft 250 receives the torque output by the torque output part 110 and is deformed, the strain gauge will also be deformed. The electrical connection part 240 can obtain the deformation of the strain gauge and transmit it to the data acquisition device, thereby obtaining the torque of the mounting nut 13 and the gripping force between the wire clamp hull 11 and the U-bolt 12; the shell 230 can play a certain protective role on the part of the transmission shaft 250 inside it, preventing the transmission shaft 250 from being deformed due to external factors such as bumps, thereby ensuring data accuracy.

[0048] Furthermore, μ c After being measured through the test, the data are recorded in the data acquisition device, so that the gripping force value between the wire clamp hull 11 and the U-bolt 12 can be obtained through the external data acquisition device.

[0049] In one embodiment, the electrical connection portion 240 is electrically connected to the data acquisition device via wires, which has low implementation costs and reliable transmission effects.

[0050] For explanation, the strain gauge is made of a conductor or semiconductor material, so when the strain gauge is deformed along with the transmission shaft 250, the resistance value of the strain gauge will change accordingly, and the electrical connection part 240 can monitor the change in the resistance value of the strain gauge, thereby calculating the deformation amount of the strain gauge, and then obtaining the deformation amount of the transmission shaft 250, and further calculating the torque applied to the transmission shaft 250 based on the deformation amount of the transmission shaft 250, and then obtaining the gripping force between the wire clamp hull 11 and the U-bolt 12.

[0051] Furthermore, the strain monitoring mechanism further includes a conductive slip ring, which is disposed on the transmission shaft 250 and electrically connected to the strain gauge, and is used to transmit the deformation amount of the strain gauge to the electrical connection portion 240 .

[0052] In one embodiment, the data acquisition device includes a portable data acquisition box, a dedicated cable, a lithium battery, a transmitting module, and a handheld operator, wherein the portable data acquisition box is connected to the lithium battery via a dedicated cable to form a ground data receiving end, and the transmitting module is electrically connected to the electrical connection part 240 via an electric wire.

[0053] In one embodiment, the portable data acquisition box is equipped with a wireless receiving module, a receiving antenna, a touch screen, and an early warning module. The wireless receiving module is connected to an external antenna through the antenna mounting hole to realize the reception of the wireless signal of the remote torque sensor 200; the touch screen is internally configured with measurement software, which can display the torque change in real time, realize curve analysis, data storage and recording and other functions; the software also has an early warning function, and the early warning value and alarm value can be freely set. For example, when the early warning value is reached, the interface turns orange, and when the peak alarm value is reached, the interface turns red. At the same time, when the early warning value is reached, the external early warning light on the panel lights up, and when the peak value is reached, the buzzer of the wireless sending module on the tower sounds; the acquisition box is equipped with a USB interface, which can regularly export historical data and transfer it to a computer for storage.

[0054] In one embodiment, the lithium battery is connected to the portable data collection box through a dedicated cable to provide power for the portable data collection box.

[0055] In one embodiment, the transmitting module is a wireless transmitting module, which has a built-in large-capacity battery and does not require external power supply; the wireless transmitting module is connected to the electrical connection part 240 of the torque sensor 200, provides working power for the torque sensor 200, collects signal values ​​at a set frequency, and converts the collected analog signals into wireless lora signals for transmission; the wireless transmitting module has an RS485 communication interface and can communicate with a computer; an external handheld operator is also configured for near-end display of torque values ​​and periodic calibration of the equipment;

[0056] Please refer to Figures 3 and 4. In one embodiment, the installation device for the suspension clamp 10 also includes a fixing mechanism 400. The fixing mechanism 400 is provided with a first fixing component 410 and a second fixing component 420. The first fixing component 410 is connected to the housing 230, and the second fixing component 420 is connected to the torque output member 100.

[0057] The first fixing component 410 of the fixing mechanism 400 is connected to the shell 230, and the second fixing component 420 is connected to the torque output member 100. In this way, when the torque output part 110 of the torque output member 100 drives the transmission shaft 250 to rotate, the shell 230 can be prevented from rotating relative to the torque output member 100, which not only improves the accuracy of the deformation monitored by the strain gauge, but also prevents the electrical connection part 240 outside the shell 230 from rotating with the shell 230 and affecting the point connection effect between the electrical connection part 240 and the data acquisition device, thereby ensuring the stability and reliability of data transmission.

[0058] Furthermore, since the electrical connection portion 240 outside the shell 230 is electrically connected to the external data acquisition device through wires, the fixing mechanism 400 is provided to prevent the shell 230 from rotating relative to the torque output member 100, thereby preventing the shell 230 from rotating and causing the wires to be entangled on the shell 230.

[0059] Please refer to Figures 3 and 4. In one embodiment, the fixing mechanism 400 includes a fixing arm 430, the first fixing portion includes a first clamping jaw 411, and the second fixing portion includes a second clamping jaw 421. The first clamping jaw 411 and the second clamping jaw 421 are arranged on the fixing arm 430 at intervals along the length direction of the fixing arm 430. The first clamping jaw 411 is clamped on the shell 230, and the second clamping jaw 421 is clamped on the torque output member 100.

[0060] The first clamping jaw 411 and the second clamping jaw 421 provided on the fixed arm 430 clamp and fix the housing 230 and the torque output member 100 respectively, to prevent the housing 230 from rotating together with the transmission shaft 250 when the torque output part 110 drives the transmission shaft 250 to rotate; the assembly process is simple and the implementation cost is low.

[0061] Furthermore, the first clamping jaw 411 is disposed at one end of the fixed arm 430 , and the second clamping jaw 421 is disposed at the other end of the fixed arm 430 .

[0062] In one embodiment, the first clamping jaw 411 and the second clamping jaw 421 are both connected to the fixing arm 430 by screwing.

[0063] Please refer to Figure 4. In one embodiment, the fixing mechanism 400 also includes a fixing knob 440 and a fixing bolt 450. The fixing arm 430 includes a first arm segment 431 and a second arm segment 432. The first arm segment 431 is provided with a first strip hole 4311 and is connected to the first clamping jaw 411. The second arm segment 432 is provided with a second strip hole 4321 and is connected to the second clamping jaw 421. The axial direction of the first strip hole 4311 and the axial direction of the second strip hole 4321 are both extended along the length direction of the fixing arm 430. The fixing knob 440 is provided with a fixing screw hole. The fixing bolt 450 is passed through the first strip hole 4311 and the second strip hole 4321 and is screwed with the fixing screw hole.

[0064] The fixing bolt 450 is sequentially passed through the first strip hole 4311 of the first arm segment 431 and the second strip hole 4321 of the second arm segment 432, so that the first arm segment 431 and the second arm segment 432 can reciprocate along the length direction of the fixed arm 430, thereby adjusting the overall length of the fixed arm 430 and the distance between the first clamping jaw 411 and the second clamping jaw 421, so that the first clamping jaw 411 and the second clamping jaw 421 can adapt to torque sensors 200 and torque output members 100 of different shapes and sizes, thereby reducing the production cost of the mounting device.

[0065] Please refer to FIG. 4 . In one embodiment, the fixed knob 440 is provided with a symmetrical knob sheet to facilitate the staff to rotate the fixed knob 440 through the knob sheet.

[0066] Please refer to FIG. 3 and FIG. 5 . In one embodiment, the torque output portion 110 is provided with a first assembly protrusion, and the first connection portion 210 is provided with a first assembly groove. The first assembly protrusion is assembled with the first assembly groove.

[0067] The first assembly protrusion of the torque output part 110 and the first assembly groove of the first connection part 210 are assembled with each other. When the torque output part 110 rotates, the torque sensor 200 can be driven to rotate. The implementation cost is low and the process is reliable.

[0068] For example, the shape of the first assembly protrusion can be a bar, triangle, square, plum blossom or other polygonal shape, and the shape of the first assembly groove matches the shape of the first assembly protrusion, so that the torque output unit 110 drives the torque sensor 200 to rotate together.

[0069] In other embodiments, the torque output portion 110 is provided with a second assembly groove, the first connection portion 210 is provided with a second assembly protrusion, and the second assembly groove is assembled with the first assembly protrusion.

[0070] Similar to the above-mentioned embodiment, in this embodiment, the synchronous rotation of the torque output part 110 and the torque sensor 200 is achieved by the assembly between the second assembly protrusion and the second assembly groove, which will not be described in detail here.

[0071] Please refer to FIG. 3 and FIG. 5 . In one embodiment, the second connection portion 220 is provided with a third assembly protrusion, and the end of the nut sleeve 300 away from the accommodating groove 310 is provided with a third assembly groove, and the third assembly protrusion is assembled with the third assembly groove.

[0072] The torque sensor 200 is assembled with the third assembly protrusion on the second connecting part 220 and the third assembly groove of the nut sleeve 300. When the torque output part 110 drives the torque sensor 200 to rotate, it can also drive the nut sleeve 300 to rotate, thereby tightening the mounting nut 13 of the suspension clamp 10.

[0073] For example, the shape of the third assembly protrusion can be a bar, triangle, square, plum blossom or other polygons, and the shape of the third assembly groove matches the shape of the third assembly protrusion, so that the torque sensor 200 drives the nut sleeve 300 to rotate together.

[0074] Further, please refer to Figures 6 and 7. The detachable connection between the nut sleeve 300 and the torque sensor 200 is achieved by the assembly between the third assembly protrusion and the third assembly groove. In this way, the nut sleeve 300 with the accommodating groove 310 matching the model of the mounting nut 13 can be flexibly replaced according to the model of the mounting nut 13, thereby improving the overall applicability of the mounting device.
