Description

Technical Field

[0001] The present application relates to the technical field of power transmission line maintenance, and in particular to a transmission line conductor end operation device and manned operation equipment. Background Art

[0002] As an important part of power transmission, ultra-high (UHV) transmission lines generally adopt a high-span design to ensure the safety and efficiency of power transmission. The height of the towers of such transmission lines is generally above 70 meters, and the safe distance between the tower crossarm and the conductor end varies from about 7 to 15 meters depending on the voltage level. Although such a design is conducive to power transmission, it brings great challenges to operators during daily line inspection and maintenance.

[0003] The traditional maintenance operation method is usually for the operator to descend from the cross arm of the tower to the conductor end with the help of an insulated ladder to carry out the operation. However, due to the large safety distance between the cross arm of the tower and the conductor end of the ultra-high (UHV) transmission line, a sufficiently long insulated ladder must be prepared before the operation, which increases the difficulty of high-altitude climbing and brings great inconvenience to the operators. The long and heavy insulated ladder is extremely difficult to carry and unfold, and usually requires the assistance of three people to complete the operation preparation. When using an insulated ladder for large-span operations, the long climbing distance and the lack of a fixed lower end of the ladder cause large shaking, which increases the safety risk of the operators. At the same time, it also makes it extremely difficult for the operators to climb in and out of the conductor end, greatly increasing the labor intensity of the operation. Although the shaking can be reduced by adding a conductor fixing hook at the bottom of the ladder, it is also very difficult to install these fixings due to the large span, which seriously affects the operation efficiency.

[0004] In summary, traditional insulating soft ladders have the problems of low operating efficiency, high operating risks, and insufficient safety protection for operators in the maintenance of ultra-high and extra-high voltage transmission lines. Summary of the invention

[0040] Referring to Fig. 1, Fig. 1 shows a schematic diagram of the structure of a transmission line conductor end operation device in an embodiment of the present application. A transmission line conductor end operation device provided in an embodiment of the present application comprises a hanging and removing assembly 1, a lifting and self-locking assembly 2, a sliding assembly 3 and a rope assembly 4.

[0041] Specifically, one end of the hanging and dismantling component 1 can be clamped on the end of the wire; the lifting and self-locking component 2 is connected to the hanging and dismantling component 1, including a pulley body 20 and a sliding locking part 21, and the sliding locking part 21 is installed in the pulley body 20; the sliding component 3 is connected to the pulley body 20, including a first sliding rail 30 and a second sliding rail 31; the rope component 4, one end of which is fixed to the pulley body 20, and the other end is wound around the first sliding rail 30, the sliding locking part 21 and the second sliding rail 31; when the rope component 4 is pulled or released, the rope component 4 is driven to slide around the first sliding rail 30, the sliding locking part 21 and the second sliding rail 31, so as to drive the sliding component 3 to rise or fall.

[0042] In the specific implementation process, the operator first clamps the hanging and disassembling component 1 at the conductor end of the transmission line, and then uses the tightening or loosening operation of the rope component 4 to control the lifting and lowering of the device. When the rope component 4 is tightened, the rope component 4 will slide along the first sliding track 30, the second sliding track 31 of the sliding component 3 and the sliding locking part 21 of the lifting self-locking component 2, thereby driving the sliding component 3 and the entire device to rise. When the rope component 4 is loosened, the device will descend in the opposite direction. During the lifting process, when the rope component 4 is subjected to tension, the sliding locking part 21 will automatically lock to prevent the rope component 4 from accidentally sliding off, thereby improving the safety of the operation.

[0043] As described above, the above-mentioned transmission line conductor end operation device realizes the stable lifting and operating functions of the device on the transmission line conductor end by setting the hanging and disassembling component 1, the lifting and locking component 2, the sliding component 3 and the rope component 4 to cooperate with each other, thereby improving safety and reliability. At the same time, the overall structure of the device is simple, the operation is convenient, and the operation efficiency is improved. The above-mentioned transmission line conductor end operation device is used to replace the insulating soft ladder and is suitable for the operation environment of the ultra-high (ultra-high) voltage transmission line from the tower cross arm to the conductor end.

[0044] In one of the embodiments, the hanging and dismantling component 1 is made of a high-strength alloy material and has sufficient strength and toughness to ensure that it will not be damaged due to excessive force during operation.

[0045] In one embodiment, the lifting self-locking assembly 2 is connected to the hanging and disassembling assembly 1, and includes a pulley body 20 and a sliding locking portion 21. The pulley body 20 is made of a light and high-strength material to reduce the weight of the entire device, making it easy to carry and operate. The sliding locking portion 21 is installed inside the pulley body 20, and is used to lock the rope assembly 4 during the lifting process to prevent it from accidentally slipping, and can ensure that it is automatically locked when subjected to a certain tension, thereby ensuring the safety of the operation.

[0046] In one embodiment, the sliding assembly 3 is connected to the pulley body 20, and includes a first sliding track 30 and a second sliding track 31 arranged in parallel, which provide a stable sliding path for the rope assembly 4. In this embodiment, the sliding track is made of wear-resistant material to improve its service life and sliding efficiency. At the same time, it is necessary to ensure the friction coefficient between the rope assembly 4 and the rope assembly 4 to ensure smooth sliding.

[0047] In one embodiment, one end of the rope assembly 4 is fixed to the pulley body 20, and the other end is wound between the first sliding track 30, the sliding locking portion 21 and the second sliding track 31. The rope assembly 4 is made of high-strength fiber material and has sufficient strength and wear resistance. When the rope assembly 4 is pulled or loosened, it can be driven to slide around the first sliding track 30, the sliding locking portion 21 and the second sliding track 31, thereby driving the sliding assembly 3 and the entire device to rise or fall.

[0048] As shown in Figure 2, Figure 2 is an exploded schematic diagram of a lifting self-locking assembly 2 provided in an embodiment of the present application. In some embodiments, the pulley body 20 includes a first pulley body 201 and a second pulley body 202 that are arranged opposite to each other.

[0049] Specifically, the first pulley body 201 and the second pulley body 202 are arranged opposite to each other and fixed together to form a stable frame for carrying and supporting other components.

[0050] In one embodiment, the sliding locking portion 21 includes a first sliding locking portion 22 and a second sliding locking portion 23 .

[0051] Specifically, the first sliding locking portion 22 and the second sliding locking portion 23 are elastically connected, and the rotation directions of the two are opposite. The first sliding locking portion 22 is arranged inside the first pulley body 201, and the second sliding locking portion 23 is relatively arranged inside the second pulley body 202, so that the two locking portions can cooperate with each other when subjected to force to achieve a more reliable locking effect.

[0052] Furthermore, a spacing is provided between the first sliding locking portion 22 and the second sliding locking portion 23, the rope assembly 4 is arranged around the spacing and passes through the first sliding rail 30 and the second sliding rail 31, and the lifting and lowering operation of the device can be achieved by tightening or loosening the rope assembly 4.

[0053] As shown in Figure 3, Figure 3 is a cross-sectional schematic diagram of a lifting self-locking assembly 2 provided in an embodiment of the present application. In some embodiments, the first sliding locking portion 22 includes a first locking disk 221, a first waist-shaped centrifugal locking piece 222, a first self-tightening convex pulley 223 and a fixed locking pin 224.

[0054] Specifically, the first locking plate 221 is embedded in a surface of one side of the first pulley body 201 and serves as a main structure of the sliding locking portion 21 .

[0055] Furthermore, two first waist-shaped centrifugal locking pieces 222 are arranged oppositely and in opposite directions in the slots provided on the surface of one side of the first locking disk 221. The waist-shaped design enables the first waist-shaped centrifugal locking piece 222 to be better adapted to the disc-shaped first locking disk 221. The first waist-shaped centrifugal locking piece 222 will not cause jamming or obstruction during rotation. When falling occurs, the first waist-shaped centrifugal locking piece 222 will clamp the first locking disk 221 under the action of centrifugal force to prevent falling, and it is easy to unlock.

[0056] Furthermore, a movable waist-shaped hole 225 is provided on the first waist-shaped centrifugal locking piece 222 for accommodating a fixed locking pin 224. One end of the fixed locking pin 224 passes through the movable waist-shaped hole 225, and the other end is arranged on the surface of one side of the first self-tightening convex pulley 223, so as to realize the connection and fixation between the first waist-shaped centrifugal locking piece 222 and the first self-tightening convex pulley 223.

[0057] Furthermore, a surface of the first self-tightening cam pulley 223 away from the first waist-shaped centrifugal locking plate 222 is provided with a protrusion inclined outward from its central area, so that the first self-tightening cam pulley 223 can automatically adjust its position when subjected to force and maintain close contact with the rope assembly 4, thereby achieving a self-tightening effect.

[0058] In conjunction with Figures 4 and 5, Figures 4 and 5 are respectively a cross-sectional schematic diagram and a side schematic diagram of a lifting self-locking assembly 2 provided in an embodiment of the present application. In some embodiments, the second sliding locking portion 23 includes a second locking disk 231, a second waist-shaped centrifugal locking piece 232, a second self-tightening convex pulley 233 and a fixed locking pin 224.

[0059] Specifically, the second locking plate 231 is embedded in the surface of one side of the second pulley body 202 and serves as the main structure of the second sliding locking portion 23 .

[0060] Furthermore, two second waist-shaped centrifugal locking pieces 232 are oppositely and reversely arranged in the slots opened on one side surface of the second locking disk 231. The waist-shaped design function of the second waist-shaped centrifugal locking piece 232 is similar to that of the first waist-shaped centrifugal locking piece 222.

[0061] Furthermore, a movable waist-shaped hole 225 is opened on the second waist-shaped centrifugal locking plate 232, which is used to accommodate one end of the fixed locking pin 224 passing through the movable waist-shaped hole 225, and the other end is arranged on the surface of one side of the second self-tightening cam pulley 233, so as to realize the fixation and connection between the second waist-shaped centrifugal locking plate 232 and the second self-tightening cam pulley 233.

[0062] Furthermore, a protrusion inclined from the central area to the outside is provided on the surface of the second self-tightening convex pulley 233 away from the second waist-shaped centrifugal locking piece 232. This design is similar to the first self-tightening convex pulley 223, so that it can automatically adjust its position when subjected to force, maintain close contact with the rope assembly 4, and achieve a self-tightening effect. In addition, the friction between the rope assembly 4 is increased, and the slippage of the rope assembly 4 is reduced, so that the transmission efficiency is higher and the operation is smoother.

[0063] Furthermore, the first self-tightening cam pulley 223 and the second self-tightening cam pulley 233 are arranged opposite to each other to form a deep "V"-shaped structure, which effectively increases the clamping force of the pulley on the rope, prevents the rope from sliding relative to each other during operation, and thus improves stability and safety.

[0064] Furthermore, a certain distance is provided between the second self-tightening cam pulley 233 and the first self-tightening cam pulley 223 to accommodate the winding of the rope assembly 4, thereby ensuring that the rope assembly 4 can be supported and locked by the two self-tightening cam pulleys at the same time during the sliding process.

[0065] In one embodiment, two fixing columns 24 and two torsion springs 25 are also included.

[0066] Specifically, one end of one of the fixing columns 24 is disposed in the through hole of the first waist-shaped centrifugal locking piece 222, and the other end passes through the through holes of the first self-tightening convex pulley 223 and the second self-tightening convex pulley 233, respectively, and finally is disposed in the through hole of the second waist-shaped centrifugal locking piece 232. One end of another fixing column 24 is disposed in the through hole of the other first waist-shaped centrifugal locking piece 222 distributed on the opposite side, and the other end passes through the through holes of the first self-tightening convex pulley 223 and the second self-tightening convex pulley 233, respectively, and finally is disposed in the through hole of the other second waist-shaped centrifugal locking piece 232 distributed on the opposite side. As described above, the fixing column 24 connects the two locking parts and the two self-tightening convex pulleys together to form an integral structure.

[0067] Furthermore, two torsion springs 25 are respectively sleeved on the outer circumference of the two fixing columns 24 to provide elastic restoring force so that the first waist-shaped centrifugal locking piece 222 and the second waist-shaped centrifugal locking piece 232 can return to their initial state after being subjected to force.

[0068] In one embodiment, a locking plate fixing column 26 and a supporting column 27 are also included.

[0069] Specifically, the locking plate fixing column 26 is disposed between the first locking plate 221 and the second locking plate 231, and is used to further fix the positions of the first locking plate 221 and the second locking plate 231, thereby enhancing the stability of the entire structure. The supporting cylinder 27 is disposed between the first pulley body 201 and the second pulley body 202, and is parallel to the locking plate fixing column 26 and has a spacing therebetween. This spacing is used to accommodate the passage of the rope assembly 4, ensuring that the rope assembly 4 will not be obstructed during the lifting process.

[0070] In one embodiment, a locking pin 28 and a bearing 29 are further included. The bearing 29 is respectively inserted into the corresponding channels between the first pulley body 201, the first locking plate 221, the first self-tightening cam pulley 223, the second self-tightening cam pulley 233, the second locking plate 231 and the second pulley body 202. The locking pin 28 is arranged in the bearing 29 to further fix the position of the bearing 29 to prevent it from being offset or loosened during operation.

[0071] In the specific implementation process, when the rope assembly 4 is slowly pulled, the first self-tightening convex pulley 223 and the second self-tightening convex pulley 233 respectively drive the first waist-shaped centrifugal locking piece 222 and the second waist-shaped centrifugal locking piece 232 to rotate. Since the centrifugal force generated at this time is not greater than the force of the torsion spring 25, the first waist-shaped centrifugal locking piece 222 and the second waist-shaped centrifugal locking piece 232 will not open and clamp into the first locking disk 221 and the second locking disk 231, and the lifting self-locking assembly 2 can work normally.

[0072] Furthermore, when a rapid fall or rapid pulling of the rope assembly 4 occurs, the rotation speeds of the first self-tightening cam pulley 223 and the second self-tightening cam pulley 233 accelerate, and the centrifugal force generated is greater than the force of the torsion spring 25. Under the action of the centrifugal force, the first waist-shaped centrifugal locking plate 222 and the second waist-shaped centrifugal locking plate 232 break free from the restoring force of the torsion spring 25 and open, and are respectively stuck in the first locking disk 221 and the second locking disk 231, preventing the first self-tightening cam pulley 223 and the second self-tightening cam pulley 233 from continuing to rotate, thereby preventing a falling accident from occurring.

[0073] Furthermore, when unlocking, it is only necessary to continue to slowly pull the rope assembly 4 in the direction of rotation. Due to the reduction of centrifugal force, the first waist-shaped centrifugal locking plate 222 and the second waist-shaped centrifugal locking plate 232 are reset to the initial state under the action of the torsion spring 25, and the lifting self-locking assembly 2 can work normally again.

[0074] As described above, the two pairs of first waist-shaped centrifugal locking pieces 222 and second waist-shaped centrifugal locking pieces 232 are mirror-mounted to achieve a two-way locking function. Whether rotating clockwise or counterclockwise, they can be reliably locked, which significantly improves safety. The combination design of the first self-tightening convex pulley 223 and the first waist-shaped centrifugal locking piece 222, and the second self-tightening convex pulley 233 and the third waist-shaped centrifugal locking piece utilizes the interaction between centrifugal force and torsion spring 25 to achieve an automatic locking function when falling quickly or pulling the rope quickly. The rope can be unlocked by continuing to pull it slowly, which is easy to operate.

[0075] Furthermore, a brass support ring is embedded inside the first locking disc 221 and the second locking disc 231, and the support ring can swing, which enhances stability and durability. Under the action of the first waist-shaped centrifugal locking piece 222 and the second waist-shaped centrifugal locking piece 232, after the first locking disc 221 and the second locking disc 231 rotate to a certain angle, the locking disc fixing column 26 will squeeze the rope assembly 4 onto the supporting cylinder 27 to achieve a firm fixation of the rope.

[0076] As described above, the lifting self-locking assembly 2 adopts a closed-loop structure design to maintain good structural strength, reduce product weight, and achieve dual optimization of structural strength and weight. It adopts a bidirectional centrifugal self-locking design, which can be used without installation in different directions, ensuring that it can be locked in any installation, and has a reset function, which is easy to operate. The deep "V" design effectively enhances the clamping force of the first self-tightening convex pulley 223 and the second self-tightening convex pulley 233 on the rope assembly 4, with higher transmission efficiency and greater gripping force when falling, ensuring the personal safety of users.

[0077] 6 is a schematic diagram of the structure of a sliding assembly 3 provided in an embodiment of the present application. In some embodiments, the sliding assembly 3 includes a pulley mounting frame 32, a serial fixed sheet 33, a first pulley 34, a second pulley 35, a locking pin 36 and a fixing sleeve 37.

[0078] Specifically, the pulley mounting frame 32 serves as the main structure of the sliding assembly 3 and is used to support and fix other components.

[0079] Furthermore, the serial integrated fixing piece 33 is longitudinally arranged in the middle area of ​​the pulley mounting frame 32, and is used to connect and fix the first pulley 34 and the second pulley 35. The design of the serial integrated fixing piece 33 enables the two pulleys to maintain a certain spacing and relative position, thereby ensuring the stable sliding of the rope assembly 4.

[0080] Further, the first pulley 34 and the second pulley 35 are respectively arranged on both sides of the serial integral fixing plate 33. The structures of the two pulleys can be the same or different, depending on the operation requirements. In this embodiment, the first pulley 34 and the second pulley 35 respectively have a first sliding track 30 and a second sliding track 31 for accommodating and guiding the rope assembly 4.

[0081] Furthermore, one end of the locking pin 36 is transversely inserted into the through holes between the pulley mounting frame 32, the first pulley 34, the serial fixed sheet 33 and the second pulley 35. The function of the locking pin 36 is to facilitate fixing all components together to form an integral structure, ensure the stability and reliability of the sliding assembly 3, reduce the time of installation and disassembly during high-altitude operations, and improve the operation efficiency.

[0082] Furthermore, the fixing sleeve 37 is connected to the serially mounted fixing piece 33 for connection with the manned operation equipment.

[0083] In the specific implementation process, the sliding assembly 3 is used as a fixed pulley, and the rope assembly 4 is wound twice around the first pulley 34 and the second pulley 35. Each winding will halve the required tension, that is, only 1 / 2 of the original tension is required after winding once, and only 1 / 4 of the original tension is required after winding twice.

[0084] Furthermore, a more labor-saving and staggered rope winding method is adopted to connect and transmit the lifting self-locking component 2 and the sliding component 3, which significantly reduces the pulling force required for the operation and achieves a more labor-saving effect. At the same time, through the self-descent method, the operator can easily bring himself to the designated operation area without manual rope pulling, and can be completed by slowly releasing the rope.

[0085] 7 is a schematic diagram of the structure of a hanging and dismantling assembly 1 provided in an embodiment of the present application. In some embodiments, the hanging and dismantling assembly 1 includes a movable hook body 10, a first movable clamping block 11 and a second movable clamping block 12.

[0086] Specifically, the movable hook body 10 is a core component of the hanging and dismantling assembly 1. The movable hook body 10 is designed to be long and has certain strength and toughness, and can withstand various forces during the operation process.

[0087] Furthermore, the first movable clamping block 11 is protruding from one side of the movable hook body 10, and its shape and size are designed according to the shape and size of the wire end to ensure that it can be tightly clamped on one side of the wire end. One end of the first movable clamping block 11 is connected to one side of the movable hook body 10, and the other end extends horizontally and bends downward to form a clamping structure.

[0088] Furthermore, the second movable clamping block 12 is arranged on the movable hook body 10 below the first movable clamping block 11, and its shape and size match the first movable clamping block 11, ensuring that it can be clamped on the other side of the wire end. Among them, one end of the second movable clamping block 12 is sleeved on the outer periphery of the movable hook body 10 and can slide along the movable hook body 10, and the other end extends horizontally and bends upward, forming a clamping structure for the wire end together with the first movable clamping block 11.

[0089] In one embodiment, the hanging and dismantling assembly 1 further includes a locking nut 13 and a padlock pin 14 .

[0090] Specifically, the locking nut 13 is used to clamp the connection between the first movable clamping block 11, the second movable clamping block 12 and the wire end. The locking nut 13 can be screwed on the movable hook body 10, and exert pressure on the first movable clamping block 11 and the second movable clamping block 12 through its threaded structure to ensure that the hanging and disassembling assembly 1 can be firmly hung on the wire end.

[0091] Furthermore, a padlock pin 14 is disposed below the movable hook body 10 to further fix the position of the hanging and disassembling assembly 1 to prevent it from accidentally falling off during use. A safety buckle 15 is connected between the padlock pin 14 and the lifting and self-locking assembly 2 to ensure safety during operation. When the hanging and disassembling assembly 1 is mounted on the wire end, the safety buckle 15 firmly connects the padlock pin 14 and the lifting and self-locking assembly 2 to prevent the lifting and self-locking assembly 2 from falling off or shaking during operation.

[0092] As shown in Figure 1, Figure 1 is a schematic diagram of the structure of a transmission line conductor end operation device provided in an embodiment of the present application. In some embodiments, a manned operation device is also provided, including the transmission line conductor end operation device as described above, and the sliding assembly 3 is provided with a fixing sleeve 37 connected to the manned operation device.

[0093] In one embodiment, the manned working equipment includes a manned vertical pole body 50 , a seat plate 51 and a footrest 52 .

[0094] Specifically, the manned vertical rod body 50 is the main structure of the manned operation equipment. The manned vertical rod body 50 is designed to be long and has a certain strength and rigidity, and can bear the weight of the operator and various forces during the operation. The upper end of the manned vertical rod body 50 is connected to the fixing sleeve 37 of the sliding assembly 3, and the manned vertical rod body 50 is firmly fixed to the sliding assembly 3 through the fixing sleeve 37 to ensure the stability of the entire equipment.

[0095] Furthermore, the seat plate 51 is transversely arranged on the manned vertical rod body 50 to support the buttocks of the operator and provide a comfortable sitting posture. The seat plate 51 can be designed as a structure with adjustable height and angle to adapt to the height and sitting posture requirements of different operators. The surface of the seat plate 51 can be provided with anti-slip material or anti-slip texture to increase the stability and safety of the operator during the operation.

[0096] Furthermore, the footrest 52 is disposed transversely below the manned vertical pole body 50 to support the feet of the operator and provide a stable standing or stepping platform. The footrest 52 can be designed as a structure with adjustable angle and position to adapt to different working environments and working requirements. The surface of the footrest 52 can also be provided with anti-slip material or anti-slip texture to prevent the operator from slipping or falling during the operation.

[0097] In the specific implementation process, the maintenance object is the iron tower angle steel, and the first movable clamping block 11 and the second movable clamping block 12 of the hanging and dismantling assembly 1 are respectively clamped on the two sides of the angle steel to achieve installation and fixation. Then the hanging and dismantling assembly 1 is connected to the lifting self-locking assembly 2 through the safety buckle 15, and the manned operation equipment is installed in the fixing sleeve 37 of the sliding assembly 3, and then the rope assembly 4 is connected with the lifting self-locking assembly 2 and the sliding assembly 3, so that the operator can control the lifting of the manned operation equipment by tightening or loosening the rope assembly 4, so as to reach the designated operation position for maintenance.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
