Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of live working of power line, specifically relates to a kind of for live working of disconnecting branch line lifting and parallel line device. BACKGROUND

[0002] Live disconnecting and connecting drainage line operation is the key link to ensure the continuity of power supply, and parallel groove clamp is an indispensable connecting element in the operation process. Parallel groove clamp is mainly used for connecting branch line and main line (the jump line is the branch line to be connected, and the main line is the main line of power transmission), which realizes firm clamping of cable through special structure design, so as to ensure stable transmission of current between cables.

[0003] With the expansion of distribution network scale and intelligent upgrading, the traditional operation mode faces the challenge of complex working conditions. At present, distribution network live working mainly relies on insulating glove method combined with insulating boom truck, but this method still has many defects.

[0004] On the one hand, manual lifting needs to hold the upper arm in the air, which is easy to cause fatigue; and after lifting, there is a certain torsion, that is, after the branch line is close to the main line, it is not necessarily parallel to the main line, and manual adjustment is needed, which is very difficult, and the rod body is twisted and deformed but still cannot be adjusted to the right position.

[0005] On the other hand, there is a small gap between the branch line and the transmission device and the screw rod, which causes the branch line and the transmission device to shake left and right after being transmitted to the vicinity of the main line, even without the torsion of the branch line, which affects the entry of the main line into the slot; and when the transmission device goes up, it may hit the hook device before reaching the right position.

[0006] In addition, there are significant limitations in certain scenarios, which are difficult to meet the efficient and safe operation requirements. For example, in complex urban areas, dense green belts, commercial core areas and traffic-intensive areas, due to space limitations and traffic control, it is difficult for insulating boom trucks to reach the operation position, and the environmental shielding is difficult; in mountainous areas, farmland and other rugged terrains, insulating boom trucks cannot pass, and workers need to carry tools to approach live equipment at a long distance; when multiple circuit overhead lines are needed, the activity space of workers is limited in the environment of erecting high and low voltage lines or multiple circuit lines on the same pole, and the traditional insulating rod is difficult to complete precise operation due to its single function.

[0044] The examples given are provided to better illustrate the present invention, but the content of the present invention is not limited to the examples given.

[0045] like Figures 1 to 10 As shown, a disconnection branch line lifting and paralleling device for live-line work includes a base 1, a first fixed seat 2, an insulating rod 4, a second fixed seat 3, a clamping seat 5, and a main line support 6.

[0046] The first fixing seat 2 is fixed on the base 1, and the second fixing seat 3 is disposed above the first fixing seat 2;

[0047] The lower end of the insulating rod 4 is fixedly connected to the first fixed base 2, and the upper end is fixedly connected to the second fixed base 3;

[0048] The clamping seat 5 is slidably connected to the insulating rod 4 and is used to clamp the parallel groove clamp 7. The clamping seat 5 can drive the parallel groove clamp 7 to move towards the second fixed seat 3.

[0049] 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 are close to each other and the main line is embedded in the groove 16 of the wire clamp 7.

[0050] The lifting device in this invention is suitable for installing the commonly used parallel groove clamp 7. The base 1 mainly supports the entire lifting device. In use, the operator first inserts the branch line into the parallel groove clamp 7, and then clamps the parallel groove clamp 7 onto the clamping seat 5. After completing the above preparations, the operator holds the base 1 and lifts the entire device upwards, moving the main line bracket 6 to a position roughly level with the main line, and hooks the main line with the main line bracket 6. After hooking the main line, the clamping seat 5 is moved upwards until the groove 16 of the parallel groove clamp 7 on the clamping seat 5 is at the same horizontal level as the main line. Then, the main line bracket 6 is driven to move along the direction of the second fixed seat 3, so that the clamping seat 5 and the main line bracket 6 move closer to each other until the main line is embedded in the groove 16. After the main line is embedded in the groove 16, the groove 16 is clamped, and the locking of the parallel groove clamp 7 is released. Then, the lifting device can be removed. In this 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.

[0051] The lifting device of this utility model replaces the traditional manual lifting, which solves the problem of easy fatigue of the upper arm when lifting manually. When using it, you only need to hang the main line, and the clamp seat 5 drives the wire clamp 7 to move closer to the main line, so that the main line is embedded in the wire groove 16. This solves the problem of difficulty in connecting the wire clamp and the main line in the traditional installation method.

[0052] like Figure 1 , Figures 3 to 6 , Figures 8 to 10 As shown, in this utility model, the clamping base 5 includes a clamping plate 501 and a fixing plate 502.

[0053] The clamping plate 501 is engaged with the parallel groove clamp 7. The clamping plate 501 is provided with a clamp fixing groove 8, and a clamp clamp 9 that engages with the clamp fixing groove 8 is also provided at one end near the insulating rod 4. The clamping plate 501 is also provided with a wire passage 10 that matches the branch line at both ends.

[0054] The fixing plate 502 cooperates with the insulating rod 4, and the fixing plate 502 is provided with a locking clamp 11 that matches the wire threading port 10, which is used to lock the branch wire at the wire threading port 10.

[0055] In this invention, the clamping plate 501 is perpendicular to the insulating rod 4, and the fixing plate 502 is parallel to the insulating rod 4. The clamp fixing groove 8 on the clamping plate 501 is a through hole corresponding to the protrusion 29 on the parallel groove clamp 7. The protrusion 29 on the parallel groove clamp 7 is a common structure, such as the protruding strip disclosed in patent publication number CN210245759U. In this invention, the number of fixing grooves 8 is one or more, and each fixing groove 8 can fix one parallel groove clamp 7. The number of fixing grooves 8 is not limited and can be adjusted according to actual conditions, resulting in good applicability. To ensure smooth installation, this invention preferably uses two fixing grooves 8, allowing two parallel groove clamps 7 to be installed simultaneously.

[0056] The cable entry port 10 is trumpet-shaped, primarily serving a positioning and clamping function. After the branch cable is inserted into the parallel groove clamp 7, the branch cables at both ends of the parallel groove clamp 7 are rotated through the cable entry port 10. Simultaneously, the protrusion 29 of the parallel groove clamp 7 is embedded into the clamp fixing groove 8. Finally, the clamp caliper 9 is used to clamp the protrusion 29, thereby locking the parallel groove clamp 7. Common quick clamps in this utility model achieve clamping and unlocking states through a control handle, such as the quick clamp disclosed in patent publication number CN203418029U.

[0057] The locking caliper 11 is used to lock the branch line at the wire insertion port 10. After the parallel groove clamp 7 is fastened to the clamping seat 5 and the branch line is inserted into the wire insertion port 10, the locking caliper 11 is manually turned so that the end of the locking caliper 11 abuts against the bottom of the branch line at the wire insertion port 10. The locking caliper 11 of this utility model is a common horizontal quick clamp in the prior art.

[0058] like Figures 1 to 6 , Figures 8 to 10 As shown, in this utility model, a guide rail 12 is also provided on the fixing plate 502, and a pressing device 13 is slidably connected on the guide rail 12. The bottom of the pressing device 13 is provided with a press switch 14 that cooperates with the guide rail 12, and the top is connected to the fixing plate 502 through a tension spring 15. After the press switch 14 is unlocked, the pressing device 13 moves upward along the guide rail 12 and abuts against the bottom of the groove 16 on the parallel groove clamp 7 that holds one end of the branch line, and the groove 16 used to hold the main line opens.

[0059] The main function of the extrusion device 13 is to extrude the wire groove 16 located at one end of the branch line after the wire clamp 7 is installed, causing the wire groove 16 used to hold the main line to open so that the main line can be smoothly embedded into the wire groove 16. To ensure that the extrusion device 13 can smoothly abut against the wire groove 16, the upper surface of the extrusion device 13 of this invention is designed with a smooth structure, and the edge near the guide rail 12 is designed as a protrusion that matches the wire groove 16. The push switch 14 is a self-locking spring pin commonly used in the prior art, and the guide rail 12 is provided with several pin holes 30 that match the push switch 14. The tension spring 15 in this invention is in a stretched state throughout the process. In the figures of this invention, only the positional relationship is shown, and the tension spring 15 and the extrusion device 13 are not connected.

[0060] In use, first install the parallel groove clamp 7, then unlock the press switch 14, causing the pressing device 13 to move 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 at one end of the branch wire and cannot move upward. At this point, the wire groove 16 used to clamp the main wire opens. Finally, engage the press switch 14 with the pin hole 30 on the guide rail 12 to lock the pressing device 13 onto the guide rail 12.

[0061] like Figures 1 to 6 , Figures 8 to 10 As shown, in this utility model, a support frame 17 for supporting the clamping seat 5 is fixed in the middle of the insulating rod 4, and the support frame 17 and the second fixed seat 3 are fixedly connected by the first guide rod 19.

[0062] It also includes a sliding plate 18 fixedly connected to the clamping seat 5. The sliding plate 18 has a through hole in the center and 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.

[0063] The sliding plate 18 mainly drives the clamping seat 5 to move upward as a whole, bringing the wire groove 16 of the parallel groove clamp 7 to be flush with the main wire, so that the main wire can be embedded into the wire groove 16 in the future. The cooperation between 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.

[0064] like Figures 1 to 10 As shown, this utility model 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 passes around the fixed pulley and is fixed on the top of the clamping seat 5.

[0065] The clamping seat 5 can move smoothly through the cooperation of the first drive motor 23, the pull wire 25, and the fixed pulley. 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 pull wire 25 is wound around the rotating shaft 26. As the pull wire 25 is wound and tightened, the clamping seat 5 is driven upward by the pull wire 25.

[0066] In this invention, the pull wire 25 can be directly installed outside the insulating rod 4, but it is easily affected by other components during operation, and the exposed pull wire 25 is also easily damaged. Therefore, to ensure the normal use of the equipment, this invention preferably installs the pull wire 25 inside the insulating rod 4. Specifically, the insulating rod 4 in this invention has a hollow structure. One end of the pull wire 25 is fixed to the 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, then passes around the fixed pulley and is fixed to the top of the clamping seat 5. Installing the pull wire 25 inside the insulating rod 4 not only avoids the pull wire 25 from interfering with other components, but also protects the pull wire 25, making it highly practical.

[0067] like Figure 1 , Figure 2 , Figure 4 , Figures 6 to 10 As shown, in this utility model, a second drive motor 24 is provided on the second fixed base 3, and the output end of the second drive motor 24 is fixedly connected to the main line bracket 6.

[0068] It also includes a second guide sleeve 22 and a second guide rod 20. The second guide sleeve 22 is mounted on the second fixed seat 3. One end of the second guide rod 20 is fixedly connected to the main line bracket 6, and the other end passes through the second guide sleeve 22 and is suspended in the air.

[0069] 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 abuts against the handle of the wire clamp caliper 9 as it approaches the clamp seat 5, thereby pushing the handle of the wire clamp caliper 9 to unlock.

[0070] The second drive motor 24 is mainly used to drive the main line bracket 6 to move towards the direction of the second fixed frame. In actual operation, if the main line is not easy to move, the second drive motor 24 can also move relatively closer to the main line bracket 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 holds the branch line, the parallel groove wire clamp 7 will not fall off. The device of this utility model can unlock the parallel groove wire clamp 7 of the clamping seat 5 as the main line bracket 6 approaches the clamping seat 5. The unlocking is convenient and the device is highly practical. Subsequently, the locking caliper 11 can be moved from below using a long rod or other net to lock the branch line.

[0071] The device of this invention can solve the problem of difficult lifting of large-diameter branch lines. Specifically, for the operation of merging large-diameter branch lines and main lines, the large-diameter branch lines themselves have very large torque, and it is very difficult to pull them manually, and it is also very inconvenient to operate at high altitudes with live wires. However, the device of this invention has a strong load-bearing capacity. After lifting with a pull wire 25, the second drive motor 24 is used to merge the branch line and the main line. This saves effort, enables precise operation, and greatly improves work efficiency.

[0072] like Figure 1 , Figure 2 , Figure 4 , Figures 6 to 10 As shown, in this utility model, the main line bracket 6 includes a horizontal part and a vertical part. A limiting component 28 is provided on the vertical part, and the limiting component 28 is movably connected to the main line bracket 6. After the main line bracket 6 hooks the main line, the limiting component 28 limits the main line.

[0073] 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 limiting component 28 and hook the main line. In this utility model, the limiting component 28 includes a connecting post 281, a locking block 282 and a nut 283. A support plate 31 is also provided on the side of the lower end of the vertical part near the second fixing seat 3. The two ends of the connecting post 281 pass through the vertical part and the support plate 31 respectively. The locking block 282 and the nut 283 are fixed to the two ends of the connecting post 281 respectively. A helical spring 284 is also sleeved on the connecting post 281. The locking block is located at the end near the second fixing seat 3, and the cross section of the locking block is a right triangle, with the two right-angled sides being horizontal and perpendicular to the insulating rod 4 respectively, and the hypotenuse being inclined.

[0074] In actual operation, first raise the main line bracket 6 to directly above the main line, then slowly move the main line bracket 6 downwards until the main line is above the inner limit component 28 of the vertical part. At this time, the limit component 28 can support the main line and prevent it from sliding down. During the downward movement of the main line bracket 6, after the bottom of the limit component's locking block contacts the main line, the main line squeezes the inclined surface of the locking block, causing the locking block to squeeze the helical spring 284. When the main line moves above the locking block, the spring returns to its original state, causing the locking block to pop out and support the main line.

[0075] In this invention, both the first drive motor 23 and the second drive motor 24 are connected to the control device 32, which controls the starting and stopping of the motors. The control device 32 is fixed to the first fixed base 2. For ease of operation, the control device 32 is also equipped with approach, exit, and emergency stop buttons. Furthermore, a distance sensor is installed on the second fixed base 3. When the clamping seat 5 moves upward into 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, a common technology in the prior art. In practical design, it is preferable that all components are wirelessly connected to the control device 32 to improve the safety of workers during construction.

[0076] The working process of this utility model is described in detail below:

[0077] Step 1: Preparation

[0078] Lower clamping seat 5 to its lowest position (specifically as follows) Figures 1 to 7 As shown), select the required number of parallel groove clamps 7. This device supports the installation of one parallel groove clamp 7 or two parallel groove clamps 7. The operator first inserts the branch line into the parallel groove clamp 7, and then tightens the parallel groove clamp 7 onto the clamping base 5. During this process, the branch line needs to be embedded into the cable entry port 10. After the parallel groove clamp 7 is tightened onto the clamping base 5, both the clamp caliper 9 and the locking caliper 11 are locked (specifically as shown). Figure 8 (As shown). Install the parallel groove clamp 7, unlock the press switch 14, and let the pressing device 13 move 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 at one end of the branch wire and cannot move upward. At this time, the wire groove 16 used to hold the main wire opens. Finally, engage the press switch 14 with the pin hole 30 on the guide rail 12 to lock the pressing device 13 onto the guide rail 12. The specific structure after the above process is completed is as follows. Figure 8 and Figure 9 As shown.

[0079] Step 2: Hook the main line

[0080] After preparation, the worker holds the base 1 and lifts the entire device upwards, raising the main line bracket 6 directly above the main line. Then, the worker slowly moves the main line bracket 6 downwards until the main line is against the inner limit component 28 of the vertical part. At this point, the limit component 28 can support the main line and prevent it from sliding down. The specific steps after hooking the main line are as follows: Figure 10 As shown.

[0081] Step 3: Move the clamping base

[0082] The first drive motor 23 is started, and the pull wire 25 is wound around the rotating shaft 26. As the pull wire 25 is wound and tightened, the clamping seat 5 is driven upward by the pull wire 25. During this process, the sliding plate 18 drives the clamping seat 5 to move upward as a whole, sending the wire groove 16 of the parallel groove clamp 7 to be flush with the main wire.

[0083] Step 4: Clamp the main line

[0084] The second drive motor 24 is started, and the output shaft of the second drive motor 24 retracts, driving the main line bracket 6 to move in the direction of the second fixed bracket. After the unlocking bracket 27 on the main line bracket 6 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 holds the branch line, the parallel groove wire clamp 7 will not fall off.

[0085] Step 5: Remove the lifting device

[0086] The operator manually releases the locking clamp 11 and tightens the bolts at the bottom of the grooved clamp 7 using the existing screw tightening device. Then, the operator lifts the entire device upwards, and the grooved clamp 7 separates from the clamping seat 5. After lifting the entire device upwards, it can be removed.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
