Description

Technical Field

[0001] The utility model relates to the technical field of electric power maintenance tools, and particularly relates to a walking device for four - split conductors of a 500kV transmission line. Background Technique

[0002] Split conductors refer to a conductor erection method adopted by extra - high - voltage transmission lines to suppress corona discharge and reduce line reactance. That is, each phase conductor is composed of several smaller - diameter sub - conductors. The sub - conductors are spaced at a certain distance and arranged in a symmetric polygon, and are arranged at the vertices of a regular polygon. The number of splits of ordinary split conductors generally does not exceed 4, and the number of split conductors of extra - high - voltage transmission lines generally takes 3 - 4.

[0003] At present, most 500kV transmission lines adopt four - split conductors. The four - split conductors are separated by cross - shaped spacer dampers. When installing, maintaining or replacing the spacer dampers, workers put on safety belts on the split conductors and then directly walk and work on the split conductors. In this way, workers can neither maintain good stability during work nor often step on the air and hang in the air during walking, with extremely high danger. Therefore, we propose a walking device for four - split conductors of a 500kV transmission line that can ensure stable operation of workers when installing, maintaining or replacing the spacer dampers.

[0030] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a 500 kV transmission line four-split conductor walking device, including a bracket 1, a main conductor wheel 2 and a carrier 3. There are two main conductor wheels 2, and the two main conductor wheels 2 are rotatably arranged on the bracket 1 and located on the left and right sides of the bracket 1. The two main conductor wheels 2 are respectively used to support two split conductors 8. An annular first groove 201 is formed by inward depression on the outer peripheral surface of the main conductor wheel 2, and the first groove 201 is used to be clamped on the corresponding split conductor 8. The carrier 3 is fixedly connected to the bracket 1 and located below the bracket 1, and the carrier 3 is used to carry workers.

[0031] For the convenience of clearly describing the use process of the 500 kV transmission line four-split conductor walking device of the present utility model, the axial direction of the main conductor wheel 2 will be defined as the left-right direction, and the horizontal direction perpendicular to the axis direction of the main conductor wheel 2 will be defined as the front-back direction in the following.

[0032] When using the 500kV transmission line four-split conductor running device described in the utility model, lift the bracket 1, lift the bracket 1 to the top of the split conductor 8, and make the main guide wheel 2 also located above the split conductor 8. Move the bracket 1 and the main guide wheel 2 until the two first grooves 201 are respectively opposite to the corresponding split conductors 8, and at this time, the support frame 3 is located between the two split conductors 8. Move the bracket 1 downward, the bracket 1 drives the main guide wheel 2 to move downward, and the first groove 201 can be stuck on the split conductor 8 opposite to it. At this time, the bracket 1 and the support frame 3 can be supported on the two split conductors 8 through the two main guide wheels 2. When the staff enters the carrier 3 and needs to change the working point, the two main guide wheels 2 are respectively rolled on the two split conductors 8. The main guide wheels 2 rolling on the split conductors 8 can drive the bracket 1 and the carrier 3 carrying the staff to move on the split conductors 8, that is, can drive the staff to change the working point. At this time, the staff can install, repair or replace the spacer at the working point. With this structure, the carrier 3 is used to carry the staff. When changing the working point, it is only necessary to make the two main guide wheels 2 roll on the two split conductors 8 respectively, that is, can drive the staff to move on the split conductors 8, and it is more convenient to change the working point; the two main guide wheels 2 are provided with a first groove 201, and the first groove 201 is clamped on the corresponding split conductor 8, so that the main guide wheels 2 are not easy to detach from the split conductor 8, and the main guide wheels 2 roll and drive the bracket 1 and the carrier 3 carrying the staff to move on the split conductor. The stability is better, which can improve the safety of the staff when working on the split conductor 8.

[0033] In this embodiment, the 500kV transmission line four-split conductor walking device described in the utility model also includes a supporting mechanism 4, and there are two supporting mechanisms 4. The two supporting mechanisms 4 are both arranged on the bracket 1, and the two supporting mechanisms 4 are respectively located on the front and rear sides of the main conductor wheel 2. The supporting mechanism 4 is used to support the two split conductors 8 upward.

[0034] When using the four - split conductor walking device for 500 kV transmission lines of the present utility model, the main conductor wheel 2 presses downward against the split conductor 8. In this solution, two of the holding mechanisms 4 are arranged on the bracket 1 and are located on the front and rear sides of the main conductor wheel 2. The holding mechanism 4 presses upward against the split conductor 8. With this structure, the split conductor 8 can be restricted between the main conductor wheel 2 and the two holding mechanisms 4 arranged on the front and rear sides of the main conductor wheel 2, which can reduce the possibility of the split conductor 8 slipping out of the corresponding first groove 201, that is, it can reduce the possibility of the main conductor wheel 2 slipping off the corresponding split conductor 8, and can improve the safety of the four - split conductor walking device for 500 kV transmission lines of the present utility model.

[0035] In this embodiment, the holding mechanism 4 includes a connecting portion 401, a secondary shaft rod 402, and secondary conductor wheels 403. The connecting portion 401 is fixedly arranged on the bracket 1. The secondary shaft rod 402 is fixedly connected to the connecting portion 401. The secondary shaft rod 402 is arranged in the left - right direction. There are two secondary conductor wheels 403, and the two secondary conductor wheels 403 are respectively rotatably arranged at both ends of the secondary shaft rod 402. The outer peripheral surfaces of the two secondary conductor wheels 403 are respectively used to press upward against the two split conductors 8.

[0036] The secondary conductor wheels 403 are connected to the bracket 1 through the secondary shaft rod 402 and the connecting portion 401, and the two ends of the secondary shaft rod 402 are both connected with the secondary conductor wheels 403. When using the four - split conductor walking device for 500 kV transmission lines of the present utility model, the secondary conductor wheels 403 connected to both ends of the secondary shaft rod 402 can respectively press upward against the two split conductors 8. With this structure, the holding mechanism 4 can press upward against the two split conductors 8. Since the two secondary conductor wheels 403 are respectively rotatably arranged at both ends of the secondary shaft rod 402, that is, when the bracket 1 drives the secondary conductor wheels 403 to move, the secondary conductor wheels 403 roll on the split conductor 8, and the friction between the secondary conductor wheels 403 and the split conductor 8 is rolling friction, and the resistance is smaller when the secondary conductor wheels 403 move.

[0037] In this embodiment, an annular second groove 4031 is recessed inward on the outer peripheral surface of the secondary conductor wheel 403. The second groove 4031 is used to be clamped on the corresponding split conductor 8. With this structure, the second groove 4031 can restrict the split conductor 8 therein and reduce the possibility of the secondary conductor wheel 403 detaching from the split conductor 8.

[0038] In this embodiment, the connecting portion 401 includes a rotating shaft 4011 and a rotating assembly 4012. The rotating shaft 4011 is fixedly provided on the bracket 1. The rotating shaft 4011 is arranged in the left-right direction. The middle part of the rotating assembly 4012 is rotatably connected to the rotating shaft 4011. The rotating assembly 4012 is slidably connected to the carrier 3 in the front-back direction. The rotating assembly 4012 can also rotate on the carrier 3. When the rotating assembly 4012 rotates on the carrier 3, the rotation center line is parallel to the rotating shaft 4011. The auxiliary shaft rod 402 is fixedly connected to the rotating assembly 4012. The connection position between the rotating assembly 4012 and the carrier 3 and the connection position between the rotating assembly 4012 and the auxiliary shaft rod 402 are respectively located on both sides of the rotating shaft 4011.

[0039] When the carrier 3 is moved upward, the carrier 3 pushes the connection position between the rotating assembly 4012 and the carrier 3 upward, so that the rotating assembly 4012 rotates about the rotating shaft 4011, and the auxiliary shaft rod 402 connected to the rotating assembly 4012 moves downward. The downward-moving auxiliary shaft rod 402 drives the auxiliary wire wheel 403 to move downward, so that the auxiliary wire wheel 403 disengages from the bundled conductor 8, thereby relieving the abutment of the auxiliary wire wheel 403 on the bundled conductor 8. At this time, it is convenient to disassemble the 500 kV transmission line four-bundled conductor walking device of the present invention from the bundled conductor 8.

[0040] When the carrier 3 is moved downward, that is, when the staff enters the carrier 3 and the carrier 3 moves downward, the carrier 3 pulls the connection position between the rotating assembly 4012 and the carrier 3 downward, so that the rotating assembly 4012 rotates about the rotating shaft 4011, and the auxiliary shaft rod 402 connected to the rotating assembly 4012 moves upward. The upward-moving auxiliary shaft rod 402 drives the auxiliary wire wheel 403 to move upward, so that the auxiliary wire wheel 403 abuts on the corresponding bundled conductor 8. Since the staff continuously applies a downward pressure to the carrier 3 after entering the carrier 3, the carrier 3 can continuously push up the auxiliary wire wheel 403 through the rotating assembly 4012 and the auxiliary shaft rod 402, and the auxiliary wire wheel 403 always abuts on the bundled conductor 8, making it difficult for the auxiliary wire wheel 403 to disengage from the bundled conductor 8.

[0041] In this embodiment, the rotating assembly 4012 includes a sleeve 40121, a first rod 40122, and a second rod 40123. The sleeve 40121 is sleeved on the outer surface of the rotating shaft 4011, and the inner cavity of the sleeve 40121 is matched with the rotating shaft 4011. The first rod 40122 and the second rod 40123 are symmetrically connected to both sides of the outer surface of the sleeve 40121. One end of the first rod 40122 is fixedly connected to the outer surface of the sleeve 40121, and the other end is fixedly connected to the auxiliary shaft rod 402. One end of the second rod 40123 is fixedly connected to the outer surface of the sleeve 40121, and the other end is slidably connected to the carrier 3 in the front-back direction. The other end of the second rod 40123 can also rotate on the carrier 3.

[0042] The first rod 40122 and the second rod 40123 are respectively connected to both sides of the outer surface of the sleeve 40121. The sleeve 40121 is sleeved on the outer surface of the rotating shaft 4011, and the inner cavity of the sleeve 40121 is matched with the rotating shaft 4011. With this structure, the middle part of the rotating assembly 4012 can be rotatably connected to the rotating shaft 4011. One end of the second rod 40123 is fixedly connected to the outer surface of the sleeve 40121, and the other end is slidably connected to the carrier 3 in the front-back direction. The other end of the second rod 40123 can also rotate on the carrier 3. With this structure, the rotating assembly 4012 can be slidably connected to the carrier 3 in the front-back direction, and the rotating assembly 4012 can also rotate on the carrier 3.

[0043] The first rod 40122 and the second rod 40123, which are respectively fixedly connected to both sides of the outer surface of the sleeve 40121, can rotate synchronously with the second rod 40123 while the second rod 40123 rotates. When the second rod 40123 rotates downward, the first rod 40122 rotates upward, and thus can drive the auxiliary wire wheel 403 to move upward to abut against the bundled conductors 8. The state where the second rod 40123 is in a downward rotation is when the staff enters the carrier 3. That is, when the staff enters the carrier 3, the carrier 3 can pull the second bracket 1 to rotate downward, thereby driving the first bracket 1 to rotate upward, and further driving the auxiliary wire wheel 403 to move upward to abut against the bundled conductors 8, which is more convenient for making the auxiliary wire wheel 403 abut against the bundled conductors 8.

[0044] In this embodiment, two chutes 301 with opposite notches are provided on the carrier 3, and the chutes 301 are arranged in the front-rear direction; the rotating assembly 4012 further includes a sliding rod 40124. The cross-section of the sliding rod 40124 is circular, and the sliding rod 40124 is arranged in the left-right direction. The sliding rod 40124 is fixedly connected to the other end of the second support rod 40123, and both ends of the sliding rod 40124 are slidably fitted in the two chutes 301 respectively. Both ends of the sliding rod can slide in the two chutes 301 respectively, and the cross-section of the sliding rod 40124 is circular. With this structure, the other end of the second support rod 40123 is slidably connected to the carrier 3 in the front-rear direction, and the other end of the second support rod 40123 can also rotate on the carrier 3.

[0045] When the carrier 3 moves upward, the sliding rod 40124 slides in the chute 301 towards the center of the chute 301, and the sliding rod 40124 also rotates in the chute 301 during the sliding process; when the carrier 3 moves downward, the sliding rod 40124 slides in the chute 301 away from the center of the chute 301, and the sliding rod 40124 also rotates in the chute 301 during the sliding process.

[0046] In this embodiment, the carrier 3 includes a frame body 302 and a seat 303, and the seat 303 is arranged in the middle of the frame body 302; the sliding rod 40124 is slidably connected to the frame body 302 in the front-rear direction.

[0047] After the staff enters the carrier 3 and sits on the seat 303, when changing the operation point or during the operation, the staff does not need to walk or stand on the bundled conductor 8, and the safety of the staff during the operation on the bundled conductor 8 is relatively high.

[0048] In this embodiment, the 500 kV transmission line four-bundled conductor walking device of the present utility model further includes a main spindle 5, bearings 6 and a driving mechanism 7. A through hole 101 is formed on the bracket 1, and the through hole 101 penetrates through the left and right side surfaces of the bracket 1. There are two bearings 6, and the two bearings 6 are respectively connected to both ends of the inner wall of the through hole 101. The outer ring of the bearing 6 is fixedly connected to the inner wall of the through hole 101. The main spindle 5 passes through the inner holes of the two bearings 6, and the inner rings of the two bearings 6 are both fixedly connected to the outer surface of the main spindle 5; the two main conductor wheels 2 are respectively fixedly connected to both ends of the main spindle 5, and the driving mechanism 7 is used to drive the main spindle 5 and the main conductor wheels 2 to rotate.

[0049] The two main wire wheels 2 are rotatably connected to the bracket 1 through the main spindle rod 5. The driving mechanism 7 drives the main spindle rod 5 and the main wire wheels 2 to rotate. With this structure, when the driving mechanism 7 drives the main spindle rod 5 and the main wire wheels 2 to rotate, the main wire wheels 2 rotate on the bundled conductor 8, which can drive the bracket 1 and the carrier 3 to move on the bundled conductor 8, and then can drive the workers to change the working point, which is more convenient when changing the working point.

[0050] In this embodiment, the driving mechanism 7 includes a motor 701, a first pulley 702, a second pulley 703 and a transmission belt 704. The motor 701 can be a motor with the model YX3-100L1-4. A third groove 102 is formed on the bracket 1. The lower end of the third groove 102 communicates with the through hole 101, and the upper end communicates with the upper surface of the bracket 1. The motor 701 is arranged on the bracket 1. The first pulley 702 is coaxially connected to the output shaft of the motor 701. The second pulley 703 is coaxially connected to the main spindle rod 5. The first pulley 702 and the second pulley 703 are located at the third groove 102. The transmission belt 704 is drivingly connected to the first pulley 702 and the second pulley 703.

[0051] Start the motor 701. The rotation of the output end of the motor 701 can drive the first pulley 702 to rotate. The first pulley 702 drives the second pulley 703 to rotate through the transmission belt 704, which can drive the main spindle rod 5 coaxially connected to the second pulley 703 and the main wire wheels 2 fixedly connected to both ends of the main spindle rod 5 to rotate. With this structure, the main wire wheels 2 rotate on the bundled conductor 8, which can drive the bracket 1 and the carrier 3 to move on the bundled conductor 8, and then can drive the workers to change the working point. Using the motor 701 as the power output to drive the main wire wheels 2 to rotate is more convenient and labor-saving when changing the working point.
