Description

Technical Field

[0001] The invention relates to the technical field of cable fixing devices, and in particular to a cable leading-up fixing device for bypass operation and a leading-up method thereof. Background Art

[0002] Bypass operation in the power system is an important technical operation. Through specific equipment and methods, a part of the load or function is temporarily transferred to another system or path for maintenance, inspection or other work. Bypass operation is to transfer the load in the distribution line to the bypass system through the access of bypass equipment, so as to realize the power outage inspection of the equipment to be inspected. It can inspect and maintain the power equipment without interrupting the power supply, so as to ensure the stable operation of the power system.

[0003] In the power system, it is a common operation to pull the cable from the main line on the pole, especially in the process of raising the cable from the ground or lower position to the overhead pole to connect to the main line. The process requires the use of appropriate tools and equipment to assist the cable pulling and fix it with a fixing device at the target location.

[0004] However, in the prior art, during the cable pulling process, since the cable needs to be pulled up to a position higher than the main line, and the operator is limited by the support position, he can usually only operate at a position below the main line, and the operation process needs to pass through the main line, which not only restricts the operation, but also is not suitable for using larger operating tools for auxiliary operation, and it is difficult to meet the requirements of stable fixation and convenient fixation at the same time; in addition, in order to meet the one-to-one fixing requirements of the cables, the fixing device must have a certain span in the direction perpendicular to the cable, so when the fixing device is erected, it will be blocked by the existing line, and it is difficult to cross over to the top of the line, which is not convenient for actual operation. Summary of the invention

[0005] The object of the present invention is to provide a cable raising and fixing device for bypass operation and a raising method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A cable upper fixing device for bypass operation comprises: a clamping component, the clamping component is used to be fixed to the electric pole, and a support plate is fixedly connected to one side of the clamping component;

[0008] A telescopic component, one end of which is fixedly connected to the top of the support plate, and a cross arm is installed at the end of the telescopic component away from the holding component, and the telescopic component is used to control the lifting of the cross arm;

[0009] A retractable component, which is arranged inside the telescopic component and is used to control the expansion or folding of the cross arm;

[0010] A fixing component, wherein several fixing components are provided, and the fixing components are fixedly connected to the bottom of the cross arm, and the fixing components are used to transfer and fix the cable, and the fixing component comprises a fixing seat, and a sliding groove is provided at the bottom of the fixing seat, and a wire fixing block is slidably connected between the inner walls of the fixing seat, and one side of the wire fixing block is provided with a wire groove, and a notch with rounded corners is provided at the bottom of the fixing seat, and both sides of the fixing seat are provided with a strip-shaped through groove communicating with the interior, and one side of the wire fixing block is fixedly connected to a limiting block, and a toggle buckle is fixedly connected to the side of the wire fixing block away from the limiting block, and the toggle buckle is slidably connected to the strip through groove, and the end of the toggle buckle away from the wire fixing block extends to the outside of the fixing seat and is fixedly connected with a pull ring.

[0011] By adopting the above technical scheme, by arranging a clamping component and a retracting and extending component, it is convenient to fix the device on the pole below the main line, and by extending the retracting and extending component, the fixing component used for upward fixing can be sent to the top of the main line after the device is fixed, thereby avoiding the problem of inconvenience in crossing the line during the upward pulling process; and a fixing component that is convenient for operation using an insulating rod is provided. During the cable fixing process, it is only necessary to use the insulating rod to hang the cable in the wire groove on one side of the fixed line block, and then use the insulating rod to move the fixing seat upward through the pull ring, so that the cable hanging part can be moved to the inside of the fixing seat for fixing, which is convenient for pulling the cable upward from below the main line.

[0012] A further improvement of the technical solution of the present invention is that the telescopic component includes an outer sleeve rod, a transfer sleeve rod and an inner sleeve rod whose end face diameters decrease successively, the transfer sleeve rod is slidably connected to the inner sleeve rod and the outer sleeve rod, the top of the support plate and located inside the outer sleeve rod is fixedly connected with a first airbag, the bottom of the inner sleeve rod is fixedly connected with a cushion block, the bottom of the cushion block contacts the top of the first airbag, the bottom of the first airbag is provided with an air valve, the input end of the air valve nozzle extends to the bottom of the support plate, the side walls of the outer sleeve rod and the transfer sleeve rod are provided with a first spring latch structure, and one side of the inner sleeve rod and the transfer sleeve rod is provided with a socket used in conjunction with the first spring latch structure.

[0013] By adopting the above technical solution, the air valve is inflated by an external air pump, so that the first airbag begins to expand and pushes the transfer sleeve rod and the inner sleeve rod to move upward to achieve extension, until the transfer sleeve rod and the inner sleeve rod are extended to the longest relative to the outer sleeve rod, and the first spring latch structure is plugged and fixed with the sockets on the transfer sleeve rod and the inner sleeve rod, so that the outer sleeve rod, the transfer sleeve rod and the inner sleeve rod are in the longest state and remain fixed; at this time, the cross arm rises to the position above the line through the middle position of the main line in a vertical state (in this state, the transfer sleeve rod and the inner sleeve rod no longer rely on the first airbag for support, but are provided by the latch).

[0014] A further improvement of the technical solution of the present invention is that: the retractable and deployable component includes a linkage slide rod, which is slidably connected to the top of the inner sleeve rod, the top of the linkage slide rod is fixedly connected to a rack, the bottom of the linkage slide rod extends to the inside of the inner sleeve rod and is fixedly connected to a first lifting plate, the two sides of the inner sleeve rod are symmetrically fixedly connected to fixed plates, a gear is rotatably connected between the two fixed plates on the side close to each other, the gear is meshed with the rack, and two flip plates are symmetrically fixedly connected to the outer side of the central axis of the gear, and the flip plates are fixedly connected to the cross arm; the top of the pad is fixedly connected to a second airbag, the top of the second airbag is fixedly connected to a second lifting plate, a conducting pipe for connecting the first airbag and the second airbag is arranged inside the pad, and a pressure valve is arranged inside the conducting pipe.

[0015] By adopting the above technical solution, after the first airbag reaches its maximum state and can no longer expand, it continues to be inflated, causing the internal pressure of the first airbag to begin to increase. When the internal air pressure of the first airbag is greater than a certain threshold, the pressure valve will be turned on, causing the gas in the first airbag to be filled into the second airbag, thereby causing the second airbag to expand and push the second lifting plate upward. Furthermore, it will push the counterweight block and the first lifting plate upward, and cause the linkage slide rod and the rack to move upward, thereby causing the gear to rotate, and drive the flip plate and the cross arm to flip, and the cross arm tends to be horizontal.

[0016] A further improvement of the technical solution of the present invention is that: a second spring latch structure is fixedly connected to one side of one of the fixed plates, a socket is provided on one side of the flip plate, and the second spring latch structure is used in conjunction with the socket; a counterweight block is fixedly connected to the bottom of the first lifting plate, a first limit plate is fixedly connected to one side of the inner wall of the inner sleeve rod, and an in-position response component is provided on the top of the first limit plate, and the in-position response component is used to release the gas in the second airbag when the second spring latch structure cooperates with the socket.

[0017] By adopting the above technical solution, when the top of the first lifting plate contacts the first limiting plate, the cross arm is in a horizontal state, and the pin of the second spring latch structure is just opposite to the socket on the flip plate, so that the fixed plate and the flip plate are relatively fixed by the second spring latch. In this state, the horizontal state of the cross arm is supported by the second spring latch structure.

[0018] A further improvement of the technical solution of the present invention is that: the in-place response component includes an air valve, which is fixedly connected to the top of the first lifting plate, and a bellows is fixedly connected between the first lifting plate and the second lifting plate, and the interior of the second airbag is connected to the interior of the air valve through the bellows; a hollow cylinder is fixedly connected to the top of the first limiting plate, and a fixing frame is fixedly connected between the inner walls of the hollow cylinder, a push rod is slidably connected to one side of the fixing frame, one end of the push rod is fixedly connected to a pressure head, the outer side of the push rod is fixedly connected to a pad, the end of the push rod away from the pressure head extends to the other side of the fixing frame and is fixedly connected to a limiting buckle, the outer side of the push rod is covered with a spring, and the pressure head is used in conjunction with the air valve.

[0019] By adopting the above technical solution, when the second airbag expands to its maximum, the air valve moves accordingly and pushes the extrusion pressure head in the vertical direction. The pressure head is in the shape of a truncated cone, so during the movement of the air valve, the pressure head will be squeezed to move toward the side close to the push rod. The spring on the outside of the push rod is squeezed, and when the pressure head is facing the ejector pin on the air valve, the pad is squeezed under the action of the spring, and the pressure head squeezes the ejector pin, and the air valve opens (the air valve structure is similar to the inflation valve on a car tire, and the gas can be released by pressing the ejector pin), so that the gas in the second airbag begins to be released from the air valve, and the gas begins to be released.

[0020] A further improvement of the technical solution of the present invention is that a whistle is installed at one end of the hollow tube, the air inlet end of the whistle is communicated with the interior of the hollow tube, and the air outlet end of the whistle extends to the outside of the inner sleeve rod.

[0021] By adopting the above technical solution, a whistle is provided so that during the gas release process of the second airbag, part of the airflow directly blows toward the whistle through the hollow tube, thereby making a sound to remind the operator that the crossarm has been deployed.

[0022] A further improvement of the technical solution of the present invention is that the fixing component also includes a slot; the slot is opened on one side of the wire fixing block, and a third spring latch structure is fixedly connected to one side of the fixing seat, and the fixing part of the third spring latch structure is set as an insertion block with an inclined surface on one side, and the insertion block is used in conjunction with the slot.

[0023] By adopting the above technical solution, the wire fixing block can be freed from its restraint in the vertical direction by unlocking the third spring pin structure, so that when the upper cable needs to be removed, it is only necessary to unlock the third spring pin structure, and the elastic force of the spring on the wire fixing block can be utilized to make the wire fixing block pop down, thereby releasing the cable and facilitating the removal of the upper cable.

[0024] A further improvement of the technical solution of the present invention is that the clamping component includes two clamping hoops, both sides of the two clamping hoops are provided with staggered grooves, the two clamping hoops are staggered, both sides of the clamping hoops are fixedly connected with wing plates, one side of the wing plate is fixedly connected with two second limit plates, one side of the support plate is fixedly connected with a positioning seat, both sides of the inner wall of the positioning seat are rotatably connected with screws, a connecting rod is fixedly connected between the ends of the two screws that are close to each other, one end of one of the screws extends to the outside of the positioning seat and is fixedly connected with a screw head, the outside of the screw is threadedly connected with a slider, the slider is slidably connected to the inner wall of the positioning seat, one side of the slider is fixedly connected with a positioning splint, both sides of the positioning splint are provided with inclined surfaces, the inclined surface of the positioning splint is extruded and matched with the wing plate, and the top and bottom of the positioning splint are in contact with the second limit plate; the inner side of the clamping hoops is fixedly connected with a non-slip pad.

[0025] By adopting the above technical solution, the two clamps are arranged alternately, the positioning seat is moved close to the clamp from the central position of one of the clamps, and the screw head is rotated to make the two screws rotate synchronously, so that the two sliders move toward the side close to each other, and drive the two positioning clamps to move toward the side close to each other, and use their inclined surfaces to squeeze the wing plates, so that the two sides of the two clamps receive force toward the center simultaneously, until the inner wall of the clamp is tightly fitted with the pole, so that the clamp cannot move longitudinally relative to the pole, and the fixed installation is completed.

[0026] A further improvement of the technical solution of the present invention is that a fastening plate is fixedly connected to the outer side of the outer sleeve rod, a U-shaped fastener is connected to one side of the fastening plate by bolts, and the inner side of the U-shaped fastener and the pole are squeezed against each other.

[0027] By adopting the above technical solution, the U-shaped fastener and the fastening plate are "tightened" toward the side close to each other to share the force on the outer pole away from the pole, thereby improving the overall resistance of the device to external forces such as wind.

[0028] A method for pulling up a cable for bypass operation comprises the following steps:

[0029] S1. Stagger two clamps around the outer side of the lower end of the pole, install the fixing seat, and turn the screw head to make the two positioning clamps approach each other, squeeze the wing plate and make the inner walls of the two clamps fit tightly with the surface of the pole;

[0030] To ensure the safety and smoothness of the operation after climbing the pole, the upper pull device operation test is first carried out on the ground. The test position is the lower end of the pole, and the operator stands at a height on the ground where the operation can be carried out.

[0031] S2. Continue to fill the telescopic component with air until the telescopic component is extended to the maximum length, record the maximum length, and continue to fill the telescopic component until the cross arm is flipped to the horizontal state, and keep it for at least 5 minutes. After confirming that the upper pulling device can be normally deployed, stop supplying air, and operate the upper pulling device to fold to the initial state;

[0032] The telescopic part is expanded by filling air into it, and after the telescopic part is fully expanded, the air is continued to be filled so that the cross arm is turned to the horizontal position, so as to test whether the device can be expanded normally. After the test, the air supply is stopped and the air is released so that the telescopic part is reset under the action of gravity;

[0033] S3. According to the maximum length that the telescopic component can extend in step S2, the target height position is set by subtracting the maximum length from the height position that is at least 1.5 times the length of the crossarm of the cable, and the target height position is marked; wherein the target height position should satisfy the requirement that the distance between the lowest position of the crossarm during the rotation process and the cable is not less than 50 cm;

[0034] Considering the paths that the two ends of the crossarm pass through during the deployment process and the mutual influence between the cables, an operating distance greater than the length of the crossarm is set to avoid touching the cables during the deployment process, thereby reducing the occurrence of accidents;

[0035] S4, turn the screw head to move the two clamps away from each other until there is a 1-2 cm gap between the inner wall of the clamp and the pole, and lift the upper fixing device to the target height position in step S3, and adjust the telescopic component to below the gap between the cables; then turn the screw head again to move the positioning clamps closer to each other until the inner wall of the clamp fits tightly against the surface of the pole;

[0036] Since the components need to be balanced and stable by hand at high altitudes, and multiple clamps and positioning splints need to be fixed, it is not convenient to perform installation operations with both hands. By loosening the two clamps based on the position of the upper pull device during the test but not completely disconnecting them from the mounting base, the clamps can be moved in the vertical direction, but they cannot be removed;

[0037] S5, filling the gas medium cooled to -5°C-0°C into the telescopic component to extend the telescopic component to the maximum length, and then continuously filling the gas medium into the telescopic component to flip the cross arm to a horizontal state, and then fix the cross arm;

[0038] By providing a cooled gas medium to inflate the airbag to assist the deployment of the telescopic component, the cooled inert gas such as nitrogen has a relatively large density due to its low temperature when it is filled into the airbag, which is conducive to forming a more stable and compact gas environment in the airbag; wherein, the gas medium is selected as an inert gas, because the inert gas, especially nitrogen, has chemical stability and is not easy to react with other substances, thereby reducing damage to the airbag, and at the same time, because the inert gas has been cooled, it will not produce too much volume reduction changes with temperature changes;

[0039] S6. Heat the cables to be led upward in a water bath, and then use an insulating rod to hang the cables in the wire trough on the wire fixing block, and use the insulating rod to push the toggle buckle until the cables in the wire trough are brought into the fixing seat, and the cables in the fixed position are in a "J" shape;

[0040] Considering that the cable is relatively rigid and difficult to bend at room temperature or in a low temperature environment, and that other parts will be disturbed to varying degrees during operation, and that it is inconvenient to climb directly on the top of the cable, the cable is first heated in a water bath to soften it, and then the cable is directly hung in the wire trough for temporary fixation, and the insulating rod is used to push the toggle buckle so that the wire trough and the fixing seat cooperate to squeeze the cable into a "J" shape, with the central part only slightly bent to ensure that no damage is caused to the cable, so it will not easily slide in the axial direction, greatly improving the stability of the fixation, and during operation, since the cable is heated in a water bath and has a relatively soft texture, no other parts will be disturbed significantly during operation, and the damage caused by cable bending is reduced.

[0041] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0042] 1. The present invention provides a cable upper fixing device for bypass operation. By arranging a clamping component and a retracting and extending component, the device is conveniently fixed on the electric pole below the main line, and the retracting and extending component is extended, so that the fixing component used for upper fixing can be sent to the top of the main line after the device is fixed, thereby avoiding the problem of inconvenience in crossing the line during the upper pulling process; and a fixing component that is convenient for operation using an insulating rod is arranged. During the cable fixing process, it is only necessary to use the insulating rod to hang the cable in the wire groove on one side of the fixed line block, and then use the insulating rod through the pull ring to make the fixing seat move upward, so that the cable hanging part is pushed into the inside of the fixing seat to complete the fixing, which is convenient for the cable upper pulling operation directly from below the main line.

[0043] 2. The present invention provides a cable leading and fixing device for bypass operations. The inflation is set into two processes. The first process can expand the first airbag, and the second airbag can be expanded after it is expanded to the maximum state. The expansion of the two airbags corresponds to the extension of the two telescopic parts and the deployment of the crossarm, so that the crossarm can be extended and deployed only by inflation, thereby reducing the difficulty of operation and greatly facilitating the actual operation.

[0044] 3. The present invention provides a cable upper fixing device for bypass operation. By setting a fixing component that is convenient for fixing the cable, when fixing the cable, it is only necessary to hang the cable in the wire groove first, and then push it into the fixing seat to complete the cable fixing; at the same time, when disassembly is required, the third spring pin structure can be unlocked to make the wire fixing block lose its restraint in the vertical direction, and then when the upper cable needs to be removed, it is only necessary to unlock the third spring pin structure, and the elastic force of the spring on the wire fixing block can be used to make the wire fixing block pop up downward, thereby releasing the cable, so as to facilitate the removal of the upper cable.

[0045] 4. The present invention provides a cable upper fixing device for bypass operation, which is arranged by staggering two clamps, and then the positioning seat is moved close to the clamp from the central position of one of the clamps, and then the screw head is rotated to make the two screws rotate synchronously, so that the two sliders move toward the side close to each other, and drive the two positioning clamps to move toward the side close to each other, and use the inclined surface to squeeze the wing plate, so that the two sides of the two clamps receive force toward the center simultaneously, until the inner wall of the clamp is tightly fitted with the pole, so that the clamp cannot move in the longitudinal direction relative to the pole, and the fixed installation is completed.

[0063] The present invention is further described in detail below in conjunction with embodiments:

[0064] Example 1

[0065] like Figure 1-Figure 15 As shown, the present invention provides a cable upper fixing device for bypass operation, comprising: a clamping component, the clamping component is used to be fixed to the pole, and a support plate 1 is fixedly connected to one side of the clamping component;

[0066] A telescopic component, one end of which is fixedly connected to the top of the support plate 1, and a cross arm 10 is installed at the end of the telescopic component away from the holding component, and the telescopic component is used to control the lifting of the cross arm 10;

[0067] A retractable component, which is arranged inside the telescopic component and is used to control the cross arm 10 to be unfolded or folded;

[0068] A fixing component, wherein several fixing components are provided, and the fixing components are fixedly connected to the bottom of the cross arm 10, and the fixing components are used to transfer and fix the cables, and the fixing components include a fixing seat 9, and a slide groove is provided at the bottom of the fixing seat 9, and a wire fixing block 30 is slidably connected between the inner walls of the fixing seat 9, and one side of the wire fixing block 30 is provided with a wire groove 37, and a notch with rounded corners is provided at the bottom of the fixing seat 9, and both sides of the fixing seat 9 are provided with a strip-shaped through groove 35 communicating with the interior, and one side of the wire fixing block 30 is fixedly connected to a limiting block 36, and a toggle buckle 34 is fixedly connected to the side of the wire fixing block 30 away from the limiting block 36, and the toggle buckle 34 is slidably connected to the strip through groove 35, and the end of the toggle buckle 34 away from the wire fixing block 30 extends to the outside of the fixing seat 9 and is fixedly connected with a pull ring.

[0069] In this embodiment, by providing a clamping component and a retracting and extending component, the device is conveniently fixed on the pole below the main line, and by extending the retracting and extending component, the fixing component used for upward fixing can be sent to the top of the main line after the device is fixed, thereby avoiding the problem of inconvenience in crossing the line during the upward pulling process; and a fixing component that is convenient for operation using an insulating rod is provided. During the cable fixing process, it is only necessary to use the insulating rod to hang the cable in the wire groove 37 on one side of the wire fixing block 30, and then use the insulating rod to move the fixing seat 9 upward through the pull ring, so that the cable hanging part can be moved to the inside of the fixing seat 9 for fixation, which facilitates the cable upward pulling operation from below the main line.

[0070] like Figure 7 and Figure 8 As shown, preferably, the fixing component also includes a slot 33; the slot 33 is opened on one side of the wire fixing block 30, and a third spring latch structure 31 is fixedly connected to one side of the fixing seat 9, and the fixing part of the third spring latch structure 31 is set as an insert block 32 with an inclined surface on one side, and the insert block 32 is used in conjunction with the slot 33, and a spring is fixedly connected between the wire fixing block 30 and the top of the inner wall of the fixing seat 9.

[0071] When not in use or in need of maintenance, the upper lead line needs to be dismantled, and there are also problems such as lack of operating position and inconvenience in operation during the dismantling process;

[0072] In this embodiment, the wire fixing block 30 can be freed from its restraint in the vertical direction by unlocking the third spring pin structure 31, so that when the upper cable needs to be removed, it is only necessary to unlock the third spring pin structure 31, and the elastic force of the spring on the wire fixing block 30 can be utilized to make the wire fixing block 30 pop up downward, thereby releasing the cable to facilitate the removal of the upper cable.

[0073] like Figure 3 , Figure 6 and Fig.14 As shown, preferably, the telescopic component includes an outer sleeve rod 2, a transfer sleeve rod 3 and an inner sleeve rod 4, whose end face diameters decrease successively. The transfer sleeve rod 3 is slidably connected to the inner sleeve rod 4 and the outer sleeve rod 2. A first air bag 5 is fixedly connected to the top of the support plate 1 and located inside the outer sleeve rod 2. A cushion block 6 is fixedly connected to the bottom of the inner sleeve rod 4. The bottom of the cushion block 6 is in contact with the top of the first air bag 5. An air valve is provided at the bottom of the first air bag 5. The input end of the air valve extends to the bottom of the support plate 1. The side walls of the outer sleeve rod 2 and the transfer sleeve rod 3 are provided with a first spring latch structure 8. One side of the inner sleeve rod 4 and the transfer sleeve rod 3 are provided with a socket for use with the first spring latch structure 8.

[0074] In this embodiment, the air valve is inflated by an external air pump, so that the first airbag 5 begins to expand and pushes the transfer sleeve 3 and the inner sleeve 4 to move upward to achieve extension, until the transfer sleeve 3 and the inner sleeve 4 are extended to a long length relative to the outer sleeve 2, and the first spring latch structure 8 is plugged and fixed with the sockets on the transfer sleeve 3 and the inner sleeve 4, so that the outer sleeve 2, the transfer sleeve 3 and the inner sleeve 4 are in the longest state and remain fixed; at this time, the cross arm 10 rises from the middle position of the main line in a vertical state to a position above the line (in this state, the transfer sleeve 3 and the inner sleeve 4 are no longer supported by the first airbag 5, but by the latch).

[0075] During the above operation, the entire device is first fixed by the clamp 43 and then the lifting operation in the vertical direction is performed, thereby avoiding the occurrence of safety accidents caused by the device contacting the cable during the unfolding process.

[0076] like Figure 3 , Figure 4 and Figure 5As shown, preferably, the retractable and deployable components include a linkage slide rod 15, which is slidably connected to the top of the inner sleeve rod 4, and a rack 14 is fixedly connected to the top of the linkage slide rod 15. The bottom of the linkage slide rod 15 extends to the inside of the inner sleeve rod 4 and is fixedly connected to a first lifting plate 16. Fixed plates 11 are symmetrically fixedly connected to the two sides of the inner sleeve rod 4, and a gear 13 is rotatably connected between the sides where the two fixed plates 11 are close to each other. The gear 13 is meshed with the rack 14, and two flip plates 12 are symmetrically fixedly connected to the outer side of the central axis of the gear 13, and the flip plates 12 are fixedly connected to the cross arm 10; a second airbag 19 is fixedly connected to the top of the cushion block 6, and a second lifting plate 17 is fixedly connected to the top of the second airbag 19, and a conducting pipe 7 for connecting the first airbag 5 and the second airbag 19 is arranged inside the cushion block 6, and a pressure valve is arranged inside the conducting pipe 7.

[0077] In this embodiment, after the first airbag 5 reaches the maximum state and cannot continue to expand, inflation continues, so that the internal pressure of the first airbag 5 begins to increase. When the internal air pressure of the first airbag 5 is greater than a certain threshold, the pressure valve is turned on, so that the gas in the first airbag 5 is filled into the second airbag 19, thereby expanding the second airbag 19 and pushing the second lifting plate 17 to move upward. Further, the counterweight block 18 and the first lifting plate 16 are pushed upward, and the linkage slide rod 15 and the rack 14 are moved upward, thereby causing the gear 13 to rotate, and driving the flip plate 12 and the cross arm 10 to flip, and the cross arm 10 tends to be horizontal.

[0078] like Figure 4 , Figure 6 and Fig.13 As shown, preferably, one side of one of the fixed plates 11 is fixedly connected to a second spring latch structure 29, and a socket is provided on one side of the flip plate 12, and the second spring latch structure 29 is used in conjunction with the socket; the bottom of the first lifting plate 16 is fixedly connected to a counterweight block 18, and one side of the inner wall of the inner sleeve rod 4 is fixedly connected to a first limit plate 22, and the top of the first limit plate 22 is provided with an in-place response component, which is used to release the gas in the second airbag 19 when the second spring latch structure 29 cooperates with the socket.

[0079] Although the second airbag 19 can provide a thrust for turning over, it is a flexible structure after all, and is easily affected by external factors (such as wind) and shakes during the support process;

[0080] In this embodiment, when the top of the first lifting plate 16 contacts the first limit plate 22, the cross arm 10 is in a horizontal state, and the pin of the second spring latch structure 29 is just opposite to the socket on the flip plate 12, so that the fixed plate 11 and the flip plate 12 are relatively fixed by the second spring latch. In this state, the horizontal state of the cross arm 10 is supported by the second spring latch structure 29.

[0081] like Figure 6 , Fig.13 and Fig.15 As shown, preferably, the in-place response component includes an air valve 21, which is fixedly connected to the top of the first lifting plate 16, and a bellows 20 is fixedly connected between the first lifting plate 16 and the second lifting plate 17, and the interior of the second airbag 19 is communicated with the interior of the air valve 21 through the bellows 20; a hollow cylinder 23 is fixedly connected to the top of the first limiting plate 22, and a fixing frame 24 is fixedly connected between the inner walls of the hollow cylinder 23, and a push rod 25 is slidably connected to one side of the fixing frame 24, and a pressure head 26 is fixedly connected to one end of the push rod 25, and a pad 27 is fixedly connected to the outside of the push rod 25, and one end of the push rod 25 extends to the other side of the fixing frame 24 away from the pressure head 26 and is fixedly connected to the limiting buckle, and a spring is sleeved on the outside of the push rod 25, and the pressure head 26 is used in conjunction with the air valve 21.

[0082] In this embodiment, during the process of the second airbag 19 expanding to its maximum, the air valve 21 moves accordingly and pushes the pressing head 26 in the vertical direction. The pressing head 26 is in the shape of a truncated cone, so during the movement of the air valve 21, the pressing head 26 will be squeezed to move toward the side close to the push rod 25. The spring on the outside of the push rod 25 is squeezed, and when the pressing head 26 is facing the ejector pin on the air valve 21, the pad 27 is squeezed under the action of the spring, and the pressing head 26 squeezes the ejector pin, and the air valve 21 opens (the structure of the air valve 21 is similar to the inflation valve 21 on a tire, and the gas can be released by pressing the ejector pin), so that the gas in the second airbag 19 begins to be released from the air valve 21, and the gas begins to be released.

[0083] like Fig.13 and Fig.15 As shown, preferably, a whistle 28 is installed at one end of the hollow tube 23 , the air inlet end of the whistle 28 is communicated with the interior of the hollow tube 23 , and the air outlet end of the whistle 28 extends to the outside of the inner sleeve rod 4 .

[0084] In this embodiment, by providing a whistle 28, during the gas release process of the second airbag 19, part of the airflow directly blows toward the whistle 28 through the hollow tube 23, thereby making a sound to remind the operator that the cross arm 10 has been deployed.

[0085] Example 2

[0086] like Fig. 9 , Fig.10 and Fig.11As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the clamping component includes two clamps 43, both sides of the two clamps 43 are provided with staggered grooves 48, the two clamps 43 are staggered, both sides of the clamps 43 are fixedly connected with wing plates 44, one side of the wing plates 44 is fixedly connected with two second limit plates 38, one side of the support plate 1 is fixedly connected with a positioning seat 39, both sides of the inner wall of the positioning seat 39 are rotatably connected with screws 40, and the ends of the two screws 40 that are close to each other are fixedly connected with a A connecting rod, wherein one end of a screw rod 40 extends to the outside of the positioning seat 39 and is fixedly connected with a screw head, a slider 41 is threadedly connected to the outside of the screw rod 40, the slider 41 is slidably connected to the inner wall of the positioning seat 39, a positioning splint 42 is fixedly connected to one side of the slider 41, both sides of the positioning splint 42 are provided with inclined surfaces, the inclined surface of the positioning splint 42 is squeezed and fitted with the wing plate 44, and the top and bottom of the positioning splint 42 are in contact with the second limit plate 38; a non-slip pad 45 is fixedly connected to the inner side of the hoop 43.

[0087] The conventional clamp 43 is composed of two annular plates that "hold" and fix the pole from the front. The pole that can be held tightly cannot be too thin, otherwise the two wings of the clamp 43 will not be able to hold tightly after contact, and thus cannot be applied to thinner poles.

[0088] In this embodiment, the two clamps 43 are staggered, the positioning seat 39 is moved close to the clamp 43 from the central position of one of the clamps 43, and the screw head is rotated to make the two screws 40 rotate synchronously, so that the two sliders 41 move toward the side close to each other, and drive the two positioning clamps 42 to move toward the side close to each other, and use their inclined surfaces to squeeze the wing plates 44, so that the two sides of the two clamps 43 receive force toward the center simultaneously, until the inner wall of the clamp 43 is tightly fitted with the pole, so that the clamp 43 cannot move in the longitudinal direction relative to the pole, and the fixed installation is completed.

[0089] like Figure 1 and Figure 2 As shown, a fastening plate 47 is fixedly connected to the outer side of the outer sleeve rod 2, and a U-shaped fastener 46 is connected to one side of the fastening plate 47 via bolts, and the inner side of the U-shaped fastener 46 and the pole are pressed against each other.

[0090] After the telescopic part is extended, the center of gravity of the device is at a higher position, and the fixing point of the device only exists between the outer rod 2 and the support plate 1. When the horizontal external force away from the pole acts on the cross arm 10, the torque on the support part is large, so the force bearing capacity is limited;

[0091] In this embodiment, the U-shaped fastener 46 and the fastening plate 47 are "tightened" toward the side close to each other to share the force on the outer pole 2 away from the pole, thereby improving the overall resistance of the device to external forces such as wind.

[0092] A method for pulling up a cable for bypass operation comprises the following steps:

[0093] S1. Alternately wrap the two clamps 43 around the outer side of the lower end of the pole, install the fixing seat 39, and turn the screw head to make the two positioning clamps 42 approach each other, squeeze the wing plate 44 and make the inner walls of the two clamps 43 fit tightly with the surface of the pole;

[0094] To ensure the safety and smoothness of the operation after climbing the pole, the upper pull device operation test is first carried out on the ground. The test position is the lower end of the pole, and the operator stands at a height on the ground where the operation can be carried out.

[0095] S2, continue to fill the telescopic part with air until the telescopic part is extended to the maximum length, record the maximum length, and continue to fill the part until the cross arm 10 is turned to the horizontal state, and keep it for at least 5 minutes. After confirming that the upper pulling device can be normally unfolded, stop supplying air, and operate the upper pulling device to fold to the initial state;

[0096] The telescopic part is expanded by filling air into it, and after the telescopic part is fully expanded, the air is continuously inflated to make the cross arm 10 flip to the horizontal position, so as to test whether the device can be normally expanded. After the test, the air supply is stopped and the air is released to make the telescopic part reset under the action of gravity. During the time when the cross arm 10 maintains the horizontal state, it can be used to observe whether the state can be stably maintained, and at the same time, the second airbag 19 is gradually deflated;

[0097] S3, according to the maximum length that the telescopic component can extend in step S2 and the length of the cross arm (10), determine the target height position of the installation of the clamp (43); wherein the target height position should satisfy the minimum distance between the lowest position of the cross arm during the rotation process and the cable of not less than 50 cm;

[0098] Considering the paths that the two ends of the cross arm pass through during the unfolding process and the mutual influence between the cables, an operating distance greater than the length of the cross arm 10 is set to avoid touching the cables during the unfolding process of the cross arm 10, thereby reducing the occurrence of accidents;

[0099] S4, turn the screw head to move the two clamps 43 away from each other until there is a 1-2 cm gap between the inner wall of the clamp 43 and the pole, and lift the upper fixing device to the target height position in step S3, and adjust the telescopic component to below the gap between the cables; then turn the screw head again to move the positioning clamps closer to each other until the inner wall of the clamp is tightly fitted to the surface of the pole;

[0100] Since the components need to be balanced and stable by hand at high altitudes, and multiple clamps and positioning splints need to be fixed, it is not convenient to perform installation operations with both hands. By loosening the two clamps 43 based on the position of the upper guide device during the test but not completely disconnecting them from the mounting seat 39, the clamps can be moved in the vertical direction, but cannot be removed;

[0101] S5, filling the gas medium cooled to -5°C-0°C into the telescopic component to extend the telescopic component to the maximum length, and then continue to fill the gas medium into the telescopic component to flip the cross arm 10 to a horizontal state, and fix the cross arm 10;

[0102] By providing a cooled gas medium to inflate the airbag to assist the deployment of the telescopic component, the cooled inert gas such as nitrogen has a relatively large density due to its low temperature when it is filled into the airbag, which is conducive to forming a more stable and compact gas environment in the airbag; wherein, the gas medium is selected as an inert gas, because the inert gas, especially nitrogen, has chemical stability and is not easy to react with other substances, thereby reducing damage to the airbag, and at the same time, because the inert gas has been cooled, it will not produce too much volume reduction changes with temperature changes;

[0103] S6. Heat the cable to be led up in a water bath, and then hang the cable in the wire groove 17 on the wire fixing block 30 by using an insulating rod, and push the toggle buckle 34 by using the insulating rod until the cable in the wire groove 17 is brought into the fixing seat 9, and the fixed cable is in a "J" shape;

[0104] Considering that the cable is relatively rigid and difficult to bend at room temperature or in a low temperature environment, and that other parts will be disturbed to varying degrees during operation, and that it is inconvenient to climb directly above the cable, the cable is first heated in a water bath to soften it, and then the cable is directly hung in the wire trough for temporary fixation, and the insulating rod is used to push the toggle buckle 34 so that the wire trough cooperates with the fixing seat to squeeze the cable into a "J" shape, with the central part only slightly bent to ensure that no damage is caused to the cable, so it will not easily slide in the axial direction, greatly improving the stability of the fixation. During operation, since the cable is heated in a water bath and has a relatively soft texture, other parts will not be disturbed significantly during operation, and the damage caused by the cable bending process is reduced.

[0105] The working principle of the cable upper fixing device for bypass operation and its use method are described in detail below.

[0106] like Figure 1-Figure 15As shown, at a position convenient for operation on the ground, the two clamps 43 are brought close to the pole from both sides at different vertical heights, and then the two clamps 43 are moved toward the side close to each other in the vertical direction, so that the two clamps 43 are staggered, and then the positioning seat 39 is brought close to the clamp 43 from the central position of one of the clamps 43, and the screw head is rotated again, so that the two screws 40 rotate synchronously, thereby making the two sliders 41 move toward the side close to each other, and drive the two positioning clamps 42 to move toward the side close to each other, and use its inclined surface to squeeze the wing plate 44, so that the two sides of the two clamps 43 receive force toward the central direction synchronously, and this process makes the positioning clamp 42 extend between the second limit plate 38, so that the clamp 43 cannot move relative to the positioning clamp 42 in the longitudinal direction, and the clamp 43 and the wing plate 44 are constrained by the positioning clamp 42 and cannot move to the side away from each other, so as to realize the constraint of the clamp 43, and in this state, there is still a gap between the clamp 43 and the pole, so the clamp 43 can still move relative to the pole in the longitudinal direction.

[0107] Move the whole upward along the pole to the installation position (the operator needs to use climbing tools or auxiliary support tools for support during the process), and then continue to rotate the screw head to make the two positioning clamps 42 continue to move toward the side close to each other, and continue to squeeze the wing plate 44 to further tighten the two clamps 43 so that the clamps 43 cannot move longitudinally relative to the pole, thereby completing the fixed installation.

[0108] After completing the above-mentioned installation and fixation, two fastening plates 47 are installed by bolts from both sides of the outer rod 2, and then the U-shaped fasteners 46 are installed on the fastening plates 47 by bolts, so that there is a certain amount of extrusion between the U-shaped fasteners 46 and the pole, so as to share the overall longitudinal force and improve the overall stability.

[0109] After completing the above-mentioned installation and reinforcement, the valve mouth can be inflated with the help of an external air pump, so that the first airbag 5 begins to expand and pushes the transfer sleeve rod 3 and the inner sleeve rod 4 to move upward to achieve extension, until the transfer sleeve rod 3 and the inner sleeve rod 4 are extended to the longest relative to the outer sleeve rod 2, and the first spring latch structure 8 is plugged and fixed with the sockets on the transfer sleeve rod 3 and the inner sleeve rod 4, so that the outer sleeve rod 2, the transfer sleeve rod 3 and the inner sleeve rod 4 are in the longest state and remain fixed; at this time, the cross arm 10 rises to a position above the line through the middle position of the main line in a vertical state (in this state, the transfer sleeve rod 3 and the inner sleeve rod 4 no longer rely on the first airbag 5 for support, but are provided by the latch).

[0110] And continue to inflate, so that the internal pressure of the first airbag 5 begins to increase. When the internal air pressure of the first airbag 5 is greater than a certain threshold value, the pressure valve will be turned on, and the gas in the first airbag 5 will be filled into the second airbag 19, so that the second airbag 19 will expand and push the second lifting plate 17 to move upward. Further, the counterweight block 18 and the first lifting plate 16 will be pushed upward, and the linkage slide bar 15 and the rack 14 will move upward, so that the gear 13 will rotate, and drive the flip plate 12 and the cross arm 10 to flip, and the cross arm 10 will tend to be horizontal; when the top of the first lifting plate 16 contacts the first limit plate 22, at this time, the cross arm 10 is in a horizontal state, and the pin of the second spring latch structure 29 is just opposite to the socket on the flip plate 12, that is, the fixed plate 11 and the flip plate 12 are relatively fixed by the second spring latch. In this state, the horizontal state of the cross arm 10 is supported by the second spring latch structure 29.

[0111] In the above process, the air valve 21 pushes the pressure head 26 in the vertical direction. The pressure head 26 is in the shape of a truncated cone. Therefore, during the movement of the air valve 21, the pressure head 26 will be squeezed to move toward the side close to the push rod 25. The spring on the outside of the push rod 25 is squeezed, and when the pressure head 26 is facing the ejector pin on the air valve 21, the pad 27 is squeezed under the action of the spring, and the pressure head 26 squeezes the ejector pin, and the air valve 21 opens (the structure of the air valve 21 is similar to the inflation valve 21 on a car tire, and the gas can be released by pressing the ejector pin), so that the gas in the second airbag 19 begins to be released from the air valve 21 and the pressure begins to be relieved; in the process, part of the air flow directly blows to the whistle 28 through the hollow tube 23, thereby making a sound to remind the operator that the cross arm 10 has been deployed.

[0112] Through the above-mentioned pressure relief process, the gas in the second airbag 19 will be released (in the process, the gravity of the second lifting plate 17 will assist the compression and reset of the second airbag 19, and the second lifting plate 17 will then lose contact with the counterweight 18), so the second airbag 19 no longer provides support for the first lifting plate 16. At this time, since the second spring pin is connected with the socket on the flip plate 12, the crossarm 10 cannot be reset, and the rack 14 and the linkage slide rod 15 cannot be reset.

[0113] After the above-mentioned unfolding process is completed, the cable can be temporarily suspended in the wire groove 37 on one side of the wire fixing block 30 by using the insulating rod, and then the pull ring on the wire pulling buckle can be pushed by the insulating rod. The insulating rod can be a structure with a hook or a horizontal rod at the top. The wire fixing block 30 is pushed upward, and the plug block 32 is automatically retracted into the third spring latch structure 31 under the action of the inclined surface, so that the movement of the wire fixing block 30 will not be hindered. When the wire fixing block 30 is pushed to the point where the plug block 32 is facing the slot, the plug block 32 is ejected, thereby pushing the plug block 32 to move upward. The block 32 is inserted into the slot to complete the fixation. After the above process, the spring between the wire fixing block 30 and the fixing seat 9 is in a compressed state; the cable is partially sent into the notch at the bottom of the fixing seat 9, so that the cable is in the shape of a "J", wherein the inner wall of the wire groove 37 of the fixing seat 9 is provided with a flexible material to reduce damage to the cable; and when the cable needs to be removed, it is only necessary to use the insulating rod to unlock the third spring pin, so that the wire fixing block 30 can be ejected downward, and then the insulating rod can be used to remove the cable.

[0114] When dismantling is necessary, first remove the cable according to the above method. After the cable is disconnected from the wire fixing block 30, use the insulating rod to operate the second spring latch structure 29 to unlock it. After unlocking, due to the gravity of the counterweight block 18 and the first lifting plate 16, the linkage slide rod 15 and the rack 14 will move downward, and the gear 13 will be flipped during the process, and the cross arm 10 will flip to a vertical state.

[0115] After completing the above operations, the first spring latch structure 8 is operated from top to bottom to unlock, and the gas in the first airbag 5 is released through the valve nozzle at the same time, that is, the airbag begins to shrink under the action of gravity, and the inner sleeve rod 4, the transfer sleeve rod 3 and the outer sleeve rod 2 shrink at the same time (the inner sleeve rod 4 slides into the transfer sleeve rod 3, and the transfer sleeve rod 3 slides into the outer sleeve rod 2), and until the top of each sleeve rod contacts the shell part of the first spring latch structure 8, that is, reaching the limit of folding.

[0116] Remove the fastening plate 47 and the U-shaped fastener 46, and then rotate the screw head to make the two screws 40 rotate synchronously, and make the two sliders 41 move to the side away from each other, and drive the positioning clamping plate 42 to move to the side away from each other so that the wing plate 44 is no longer squeezed and matched. This process loosens the two clamps 43 but does not disengage to prevent the modules from falling down after high-altitude dismantling. After the clamps 43 are loosened, the whole is supported and moved downward to the ground position, and further dismantling operations can be carried out.

[0117] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
