Description

Technical Field

[0001] The invention relates to the technical field of live working on power lines, and in particular to a disconnecting branch line lifting and paralleling device and method for live working. Background Art

[0002] The operation of disconnecting the lead wire under power is a key link to ensure the continuity of power supply, and the parallel groove wire clamp is an indispensable connection element in the operation process. The parallel groove wire clamp is mainly used to connect the branch line and the main line (the jumper line is the branch line to be connected, and the main line is the main line for power transmission). Through its unique structural design, it can firmly clamp the cable, thereby ensuring the stable transmission of current between the cables.

[0003] With the expansion of distribution network scale and intelligent upgrading, traditional operation methods are facing challenges in complex working conditions. At present, live distribution network operations mainly rely on the insulated glove method with insulated boom trucks, but this method still has many defects.

[0004] On the one hand, manual lifting requires both arms to hold the equipment in the air, which can easily fatigue the upper arms; and there is a certain amount of torque after lifting, that is, after the branch line reaches the vicinity of the main line, it is not necessarily parallel to the main line. If adjusted manually, the torque is very large, and the rod body is twisted and deformed, but it still cannot be adjusted into place.

[0005] On the other hand, there is a tiny gap between the branch line and wire clamp transmission device and the lead screw, which causes the branch line and wire clamp to sway left and right after being transmitted to the vicinity of the main line, even if there is no branch line torque, affecting the main line from entering the wire groove; and may cause the transmission device to hit the hook device before it is in place when moving upward.

[0006] Furthermore, there are significant limitations in certain scenarios, making it difficult to meet the needs of efficient and safe operations. For example, in complex urban areas, densely greened streets, commercial core areas, and areas with dense traffic, due to space limitations and traffic control, it is difficult for insulated boom trucks to reach the work location, and environmental shielding is difficult; in rugged terrain such as mountainous areas and farmland, insulated boom trucks cannot pass, and operators need to carry tools to approach live equipment from a distance; when multiple circuit overhead lines are required, high and low voltage lines or multiple circuit lines are installed on the same pole, the space for operators to move is limited, and traditional insulated poles are difficult to complete precise operations due to their single function. Summary of the invention

[0007] The purpose of the present invention is to provide a disconnected branch line lifting and merging device for live working, which is easy to operate, can solve the problem of easy fatigue of the upper arm of manual lifting and the problem of difficulty in lifting large-diameter branch lines, and has good applicability and strong practicality.

[0016] Further, a support frame for carrying the clamping seat is fixed in the middle of the insulating rod, and the support frame is fixedly connected to the second fixed seat through a first guide rod;

[0017] It further includes a sliding plate fixedly connected to the clamping seat. A through hole is formed in the center of the sliding plate, and the sliding plate is sleeved on the insulating rod through the through hole. The clamping seat is slidably connected to the insulating rod through the sliding plate; a first guide sleeve cooperating with the first guide rod is further arranged on the sliding plate.

[0018] Further, it further includes a first driving motor, a wire rope and a fixed pulley; the first driving motor is fixed on the base; the fixed pulley is fixed on the second fixed seat; one end of the wire rope is fixed on the rotating shaft of the output end of the first driving motor, and the other end is fixed on the top of the clamping seat after passing around the fixed pulley.

[0019] Furthermore, the insulating rod is a hollow structure, one end of the pull wire is fixed on the rotating shaft at the output end of the first driving motor, and the other end passes through the inside of the insulating rod, and then passes around the fixed pulley and is fixed on the top of the clamping seat.

[0049] The embodiments are given to better illustrate the present invention, but the content of the present invention is not limited only to the given embodiments.

[0050] As Figures 1 to 10 shown, a device for disconnecting and connecting branch lines and lifting and merging lines for live working includes a base 1, a first fixing seat 2, an insulating rod 4, a second fixing seat 3, a clamping seat 5 and a main line bracket 6;

[0051] The first fixing seat 2 is fixed on the base 1, and the second fixing seat 3 is arranged above the first fixing seat 2;

[0052] The lower end of the insulating rod 4 is fixedly connected to the first fixing seat 2, and the upper end is fixedly connected to the second fixing seat 3;

[0053] The clamping seat 5 is slidably connected to the insulating rod 4 for clamping the parallel groove clamp 7, and the clamping seat 5 can drive the parallel groove clamp 7 to move towards the second fixing seat 3;

[0054] The main line bracket 6 is movably connected to the second fixed seat 3 and is used to hook the main line; the main line bracket 6 can move along the direction of the second fixed seat 3, so that the main line bracket 6 and the clamping seat 5 approach each other, and the main line is embedded into the wire groove 16 of the parallel groove clamp 7.

[0055] The lifting device in the present invention is suitable for installing the parallel groove clamp 7 common in the prior art. The base 1 is mainly used to carry the entire lifting device. When the present invention is in use, the staff first clips the branch line into the parallel groove clamp 7, and then clamps the parallel groove clamp 7 on the clamping seat 5. After completing the above preparatory work, the staff holds the base 1, lifts the entire device upward, moves the main line bracket 6 to a position approximately flush with the main line, and hooks the main line with the main line bracket 6. After hooking the main line, move the clamping seat 5 upward until the wire groove 16 of the parallel groove clamp 7 on the clamping seat 5 is at the same horizontal height as the main line. Then drive the main line bracket 6 to move along the direction of the second fixed seat 3, so that the clamping seat 5 and the main line bracket 6 approach each other until the main line is embedded into the wire groove 16. After the main line is embedded into the wire groove 16, clamp the wire groove 16, release the lock on the parallel groove clamp 7, and then take out the lifting device. In the present invention, the length of the insulating rod 4 can be designed according to the actual working conditions, making the installation of the parallel groove clamp more convenient and labor-saving.

[0056] Using the lifting device of the present invention to replace the traditional manual lifting solves the problem that the upper arm is easily fatigued during manual lifting. It only needs to hook the main conductor, and the clamping seat 5 drives the parallel groove clamp 7 to approach the main line, so that the main line is embedded into the wire groove 16, solving the problem of difficult butt joint between the wire clamp and the main conductor in the traditional installation method.

[0057] As Figure 1 、 Figures 3 to 6 、 Figures 8 to 10 shown, in the present invention, the clamping seat 5 includes a clamping plate 501 and a fixing plate 502.

[0058] The clamping plate 501 cooperates with the parallel groove clamp 7. A wire clamp fixing groove 8 is provided on the clamping plate 501, and a wire clamp caliper 9 matching the wire clamp fixing groove 8 is further provided at one end close to the insulating rod 4; through holes 10 matching the branch lines are also provided at both ends of the clamping plate 501;

[0059] The fixing plate 502 cooperates with the insulating rod 4, and a locking caliper 11 matching the through hole 10 is provided on the fixing plate 502 for locking the branch line at the through hole 10.

[0060] The clamping plate 501 in the present invention is perpendicular to the insulating rod 4, the fixing plate 502 is parallel to the insulating rod 4, and the wire clamp fixing groove 8 on the clamping plate 501 is a through hole opened on the clamping plate 501 corresponding to the protrusion 29 on the parallel groove wire clamp 7. The protrusion 29 on the parallel groove wire clamp 7 is a common structure, such as the protrusion disclosed in the patent with publication number CN210245759U. In the present invention, the number of fixing grooves 8 is more than one, and each fixing groove 8 can fix a parallel groove wire clamp 7. The number of fixing grooves 8 is not limited and can be adjusted according to actual conditions, and has good applicability. In order to ensure the smooth progress of the installation process, the present invention preferably has two fixing grooves 8, so that two parallel groove wire clamps 7 can be installed at the same time.

[0061] The threading opening 10 is trumpet-shaped, and mainly plays the role of positioning and clamping. After the branch line is inserted into the parallel groove clamp 7, the branch lines at both ends of the parallel groove clamp 7 are rotated through the threading opening 10, and the protrusion 29 of the parallel groove clamp 7 is embedded in the clamp fixing groove 8. Finally, the protrusion 29 is clamped by the clamp caliper 9 to achieve the locking of the parallel groove clamp 7. The common quick caliper in the present invention realizes the clamping state and the unlocking state by controlling the handle, such as the quick caliper disclosed in the patent with publication number CN203418029U.

[0062] The locking caliper 11 is used to lock the branch line at the threading opening 10. When the parallel groove wire clamp 7 is fastened to the clamping seat 5 and the branch line is inserted into the threading opening 10, the locking caliper 11 is manually moved so that the end of the locking caliper 11 is against the bottom of the branch line at the threading opening 10. The locking caliper 11 of the present invention is a common horizontal quick clamp in the prior art.

[0063] like Figures 1 to 6 , Figures 8 to 10 As shown, in the present invention, a guide rail 12 is also provided on the fixed plate 502, and a squeezing device 13 is slidably connected to the guide rail 12. A push switch 14 cooperating with the guide rail 12 is provided at the bottom of the squeezing device 13, and the top is connected to the fixed plate 502 through a tension spring 15; after the push switch 14 is unlocked, the squeezing device 13 moves upward along the guide rail 12 and presses against the bottom of the wire groove 16 on the parallel groove clamp 7 that clamps one end of the branch line, so that the wire groove 16 for clamping the main line is opened.

[0064] The function of the squeezing device 13 is mainly to squeeze the wire groove 16 located at one end of the branch line after the groove clamp 7 is installed, so that the wire groove 16 used to clamp the main line is opened, so that the main line can be smoothly embedded in the wire groove 16. In order to ensure that the squeezing device 13 can smoothly resist the wire groove 16, the upper surface of the squeezing device 13 of the present invention is designed with a smooth structure, and the edge of one side close to the guide rail 12 is designed as a protrusion matching the wire groove 16. The push switch 14 is a self-locking spring pin commonly seen in the prior art, and the guide rail 12 is provided with a plurality of pin holes 30 matching the push switch 14. The tension spring 15 in the present invention is in a stretched state throughout the whole process. In the figure of the present invention, only the positional relationship is shown, and the tension spring 15 and the squeezing device 13 are not connected.

[0065] When in use, first install the parallel groove clamp 7, then unlock the push switch 14, so that the extrusion device 13 moves upward along the guide rail 12 under the action of the tension spring 15, until the extrusion device 13 abuts against the bottom of the wire groove 16 holding one end of the branch line and cannot move upward, at which time, the wire groove 16 for holding the main line is opened. Finally, the push switch 14 is matched with the pin hole 30 on the guide rail 12 to lock the extrusion device 13 on the guide rail 12.

[0066] like Figures 1 to 6 , Figures 8 to 10 As shown, in the present invention, a support frame 17 for carrying the clamping seat 5 is fixed in the middle of the insulating rod 4, and the support frame 17 is fixedly connected to the second fixing seat 3 through a first guide rod 19;

[0067] It also includes a sliding plate 18 fixedly connected to the clamping seat 5. A through hole is opened in the center of the sliding plate 18, and the sliding plate 18 is sleeved on the insulating rod 4 through the through hole. The clamping seat 5 is slidably connected to the insulating rod 4 through the sliding plate 18; the sliding plate 18 is also provided with a first guide sleeve 21 that cooperates with the first guide rod 19.

[0068] The sliding plate 18 mainly drives the clamping seat 5 to move upward as a whole, and delivers the wire groove 16 of the parallel groove clamp 7 to be flush with the main line, so as to facilitate the subsequent embedding of the main line into the wire groove 16. The cooperation of the first guide rod 19 and the first guide sleeve can ensure the smooth operation of the clamping seat 5 during the upward movement process.

[0069] like Figures 1 to 10 As shown, in the present invention, it also includes a first drive motor 23, a pull wire 25 and a fixed pulley; the first drive motor 23 is fixed on the base 1; the fixed pulley is fixed on the second fixed seat 3; one end of the pull wire 25 is fixed on the rotating shaft 26 at the output end of the first drive motor 23, and the other end is fixed on the top of the clamping seat 5 after passing around the fixed pulley.

[0070] The first drive motor 23, the cable 25 and the fixed pulley cooperate to realize the smooth movement of the clamping seat 5. In actual use, the clamping seat 5 is supported by the support frame 17. After the parallel groove clamp 7 is installed, the first drive motor 23 is started, and the cable 25 is wound around the rotating shaft 26. As the cable 25 is wound and tightened, the clamping seat 5 is driven by the cable 25 to move upward.

[0071] In the present invention, the pull wire 25 can be directly set outside the insulating rod 4, but it is easily affected by other components during operation, and the pull wire 25 is easily damaged when exposed to the outside. Therefore, in order to ensure the normal use of the equipment, the present invention preferably sets the pull wire 25 inside the insulating rod 4. Specifically, the insulating rod 4 in the present invention is a hollow structure, one end of the pull wire 25 is fixed on the rotating shaft 26 at the output end of the first drive motor 23, and the other end passes through the inside of the insulating rod 4, and then passes around the fixed pulley and is fixed on the top of the clamping seat 5. The present invention sets the pull wire 25 inside the insulating rod 4, which can not only avoid the straight line mutual influence between the pull wire 25 and other components, but also protect the pull wire 25, and has strong practicality.

[0072] like Figure 1 , Figure 2 , Figure 4 , Figures 6 to 10 As shown, in the present invention, a second drive motor 24 is disposed on the second fixing seat 3, and an output end of the second drive motor 24 is fixedly connected to the main line support 6;

[0073] It also includes a second guide sleeve 22 and a second guide rod 20. The second guide sleeve 22 is arranged on the second fixing seat 3. One end of the second guide rod 20 is fixedly connected to the main line support 6, and the other end passes through the second guide sleeve 22 and is suspended in the air.

[0074] It also includes an unlocking bracket 27 fixed on the main line bracket 6. The unlocking bracket 27 moves synchronously with the main line bracket 6, and in the process of approaching the clamping seat 5, it abuts against the handle of the wire clamp caliper 9 and pushes the handle of the wire clamp caliper 9 to achieve unlocking.

[0075] The second drive motor 24 is mainly used to drive the main line support 6 to move in the direction where the second fixed frame is located. During actual operation, if the main line is not easy to move, the second drive motor 24 can also move relatively to the direction close to the main line support 6. After the unlocking bracket 27 contacts the wire clamp caliper 9, the wire clamp caliper 9 releases the lock on the parallel groove wire clamp 7. At this time, since the locking caliper 11 still clamps the branch line, the parallel groove wire clamp 7 will not fall. The device of the present invention can unlock the parallel groove wire clamp 7 by the clamping seat 5 when the main line support 6 approaches the clamping seat 5. The unlocking is convenient and practical. Subsequently, it is only necessary to use a long rod or the like to move the locking caliper 11 at the bottom to achieve the locking of the branch line.

[0076] The device of the present invention can solve the problem of difficult lifting of large-diameter branch lines. Specifically, for the operation of merging a large-diameter branch line and a main line, the torque of the large-diameter branch line itself is very large, and it is very laborious to pull it manually, and it is very inconvenient to operate during live working at high altitude; while the device of the present invention has a strong load-bearing capacity. After the branch line is lifted by the guy wire 25, the second drive motor 24 is used to merge the branch line and the main line. While saving labor, precise operation can be achieved, greatly improving work efficiency.

[0077] As Figure 1 , Figure 2 , Figure 4 , Figures 6 to 10 As shown in

[0078] The horizontal part is mainly used to fix the unlocking bracket 27 and the second guide rod 20. The vertical part is mainly used to fix the limit component 28 and hook the main line. In the present invention, the limit component 28 includes a connecting column 281, a clamping block 282 and a nut 283. A support plate 31 is also provided on one side of the lower end of the vertical part close to the second fixing seat 3. The two ends of the connecting column 281 respectively penetrate through the vertical part and the support plate 31. The clamping block 282 and the nut 283 are respectively fixed at the two ends of the connecting column 281. A spiral spring 284 is also sleeved on the connecting column 281; the clamping block is located at the end close to the second fixing seat 3, and the cross section of the clamping block is a right triangle, and the two right sides are respectively horizontal and vertical to the insulating rod 4, and the hypotenuse is inclined.

[0079] During actual operation, first lift the main line bracket 6 above the main line, and then slowly move the main line bracket 6 downward until the main line touches above the limit component 28 on the inner side of the vertical part. At this time, the limit component 28 can support the main line to prevent it from sliding down. During the downward movement of the main line bracket 6, after the bottom of the clamping block of the limiting member touches the main line, the main line presses the inclined surface of the clamping block so that the clamping block presses the spiral spring 284. When the main line moves above the clamping block, the spring returns to its original state and the clamping block pops out to support the main line.

[0080] In the present invention, the first drive motor 23 and the second drive motor 24 are both connected to the control device 32, and the start and stop of the motors are controlled by the control device 32. The control device 32 in the present invention is fixed on the first fixed seat 2. For the convenience of operation, a closing button, an exit button and an emergency stop button are further arranged on the control device 32. In addition, a distance sensor is further arranged on the second fixed seat 3 of the present invention. When the clamping seat 5 moves upward to the in-place position, the distance sensor transmits data back to the control device 32 and controls the clamping seat 5 to stop moving. The control device 32 can be a microprocessor common in the prior art. In actual design, it is preferred that each component is connected to the control device 32 in a wireless manner to improve the safety of the staff during construction.

[0081] The method for using the device of the present invention is specifically as follows:

[0082] Step S1: Fix the parallel groove clamp 7 on the lifting and parallel connection device, and tightly clamp the branch wire on the parallel groove clamp 7;

[0083] Step S2: Move the parallel groove clamp 7 close to the main wire. After the main wire and the branch wire are paralleled, remove the lifting and parallel connection device.

[0084] Further, in step S1, the parallel groove clamp 7 is fixed on the clamping seat 5; in step S2, the main wire bracket 6 is used to hook the main wire and then move close to the parallel groove clamp 7 on the clamping seat 5.

[0085] The working process of the present invention is described in detail below:

[0086] The first step: Preparation work

[0087] Lower the clamping seat 5 to the lowest position (specifically as Figures 1 to 7 shown), select the number of parallel groove clamps 7 to be installed. This device supports installing one parallel groove clamp 7 or two parallel groove clamps 7. The staff first insert the branch wire into the parallel groove clamp 7, and then tightly clamp the parallel groove clamp 7 on the clamping seat 5. During this process, the branch wire needs to be embedded into the wire threading opening 10. After the parallel groove clamp 7 is tightly clamped on the clamping seat 5, lock both the wire clamp pliers 9 and the locking pliers 11 (specifically as Figure 8 shown). After installing the parallel groove clamp 7, unlock the pressing switch 14, so that the pressing device 13 moves upward along the guide rail 12 under the action of the tension spring 15 until the pressing device 13 abuts against the bottom of the wire groove 16 clamping the branch wire end and cannot move upward. At this time, the wire groove 16 for clamping the main wire opens. Finally, fit the pressing switch 14 with the pin hole 30 on the guide rail 12 to lock the pressing device 13 on the guide rail 12. The structure after the above process is completed is specifically as Figure 8 and Figure 9 shown.

[0088] The second step: Hook the main wire

[0089] After the preparation work is completed, the staff holds the base 1, lifts the entire device upward, raises the main line bracket 6 above the main line, and then slowly moves the main line bracket 6 downward until the main line touches above the inner limit component 28 of the vertical part. At this time, the limit component 28 can hold the main line to prevent it from slipping downward. After hooking the main line, it is specifically as Figure 10 shown.

[0090] Step 3. Move the clamping seat

[0091] Start the first driving motor 23, and the pulling wire 25 winds around the rotating shaft 26. As the pulling wire 25 winds and tightens, the clamping seat 5 is driven by the pulling wire 25 to move upward. During this process, the sliding plate 18 drives the clamping seat 5 to move upward as a whole, and the wire groove 16 of the parallel groove clamp 7 is sent to be flush with the main line.

[0092] Step 4. Clamp the main line

[0093] Start the second driving motor 24, and the output shaft of the second driving motor 24 retracts, driving the main line bracket 6 to move in the direction of the second fixing bracket. After the unlocking bracket 27 on the main line bracket 6 touches the line clamp caliper 9, the line clamp caliper 9 releases the locking of the parallel groove clamp 7. At this time, since the locking caliper 11 still clamps the branch line, the parallel groove clamp 7 will not fall off.

[0094] Step 5. Remove the lifting device

[0095] The staff manually releases the locking of the locking caliper 11 and tightens the bolts at the bottom of the parallel groove clamp 7 through an existing screw tightening device. Subsequently, the staff lifts the entire device upward, and the parallel groove clamp 7 can be separated from the clamping seat 5. After lifting the entire device upward, it can be removed.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
