Description

Technical Field

[0001] This invention relates to the field of conductor erection technology, and in particular to a traction device for erecting conductors on outdoor power towers. Background Technology

[0002] During the construction of overhead power transmission tower conductors, a step-by-step traction process is commonly used. First, a small-diameter guide rope is pulled out, and then a larger-diameter traction rope is pulled out step by step from the guide rope to finally complete the laying of the transmission conductor. On the traction field side, the guide rope and the traction rope must be wound separately on independent rope reels and cannot share the same drum. The two ropes have different diameters and breaking loads, and mixing them can easily cause rope compression damage. Moreover, after completion, the two types of ropes need to be transported and reused separately. It is difficult to separate them after mixing. At the same time, the rotation or bending connector joint between the two must not be wound into the rope reel. When the joint is close to the winding position, the machine must be stopped to disassemble the joint and carry out the reel replacement operation. The rope is wound evenly and orderly on the rope reel, which can avoid rope compression, rope tangling, and damage to the strands, and ensure that the guide rope and traction rope can be reused. The field construction site environment is complex. When the joint reaches the winding position, the machine must be stopped to carry out the rope reel replacement operation.

[0003] An investigation revealed that a Chinese patent discloses a power tower conductor erection traction machine and its usage method (Publication No.: CN116388056A), which includes a movable base. A traction mechanism is installed on the top of the movable base, and a cutting mechanism is connected to the right side of the traction mechanism. The inner cavity of the movable base is equipped with a moving mechanism that works in conjunction with the traction mechanism and the cutting mechanism. This traction machine, through a power switching structure, can realize three working modes: individual cable laying, individual equipment movement, and simultaneous movement and laying. It is also equipped with a cutting mechanism that can complete cable cutting and cable sheath circumferential cutting operations.

[0004] While the aforementioned patent achieves multi-functional integration of traction and cable laying, equipment movement, and cable cutting and stripping through the setting of traction, movement, and cutting mechanisms, thus improving equipment integration and adapting to field tower erection operations, this device does not optimize the winding and coiling process of the guide rope and traction rope. In the tension-laying and step-by-step traction operation, in order to ensure uniform winding of the guide rope and traction rope, the rope needs to be continuously adjusted back and forth in lateral position during the winding process. When the rope moves back and forth, the connection joints between guide ropes and traction ropes of different thicknesses are even more difficult for workers to observe and identify with the naked eye. When the joint reaches the winding station, under the existing operation mode, workers need to stop the machine, untie the connection joints between the thick and thin guide ropes, fix the end of the thicker traction rope to a brand new empty rope reel, and then continue the winding operation. Due to the constraint of having to disassemble and replace the rope reel, it is difficult to achieve rapid reel replacement operation, and the on-site machine stoppage for disassembling and assembling the rope reel is time-consuming.

[0005] Therefore, this application provides an outdoor power tower conductor erection traction device to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an outdoor power tower conductor erection traction device to solve the problems of poor rope winding uniformity, difficulty in manual identification of joints, and long downtime for on-site rope reel replacement.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] An outdoor power transmission tower conductor erection traction device includes a traction machine body and a frame. A sliding frame is slidably connected to the frame, and a rope reel is mounted on the sliding frame. An installation shaft is rotatably connected to the frame.

An adjustment mechanism is provided between the frame and the rope reel. The adjustment mechanism is used to adjust the position of the rope winding. The adjustment mechanism includes a drive shaft, a ring frame, a ring box, a guide groove, and a movable block. A feedback component is provided inside the ring box. The feedback component is used to identify and provide feedback on the joints between ropes. The feedback component includes an arc plate, an arc block, an insulating block, and two metal blocks.

[0009] Optionally, the drive shaft is rotatably connected to the frame via a connecting shaft, the annular frame is sleeved on the drive shaft and movably connected to the drive shaft, a limit rod is fixedly connected to the frame, a limit frame is fixedly connected to the side wall of the annular frame, and the limit frame is slidably connected to the limit rod.

[0010] Optionally, the guide groove is formed on the outer wall of the drive shaft, and the guide groove includes two spiral grooves connected end to end. The movable block is fixedly connected to the annular frame and movably connected within the guide groove.

[0011] Optionally, the conical platform is fixedly connected to the end of the rope reel, and a slot is provided on the conical platform. A cavity is provided inside the mounting shaft, and one end of the insert block slides through the outer wall of the cavity and is adapted to the slot.

[0012] Optionally, a connecting block is slidably connected inside the cavity, the other end of the insert block is fixedly connected to the connecting block, a first spring is fixedly connected between the connecting block and the inner wall of the cavity, and multiple push blocks are slidably connected to the outer wall of the mounting shaft, and the push blocks are fixedly connected to the connecting block.

[0013] Optionally, a motor is mounted on the frame, the output shaft of the motor is coaxially fixed with the mounting shaft, and a pulley assembly is provided between the connecting shaft and the output shaft of the motor.

[0014] Optionally, a mounting frame is rotatably connected to the sliding frame, the end of the rope reel is movably connected between the mounting frame and the sliding frame, and the end of the mounting frame is bolted to the sliding frame.

[0015] Optionally, the annular frame is fixedly connected to the bottom of the annular frame, and symmetrical sliding grooves are provided on the side wall of the annular frame. The arc-shaped plate and the arc-shaped block are both set inside the annular frame.

[0016] Optionally, the arc-shaped plate and the arc-shaped block are slidably connected, and multiple second springs are fixedly connected between the arc-shaped block and the arc-shaped plate. The insulating block is fixedly connected to the side wall of the arc-shaped block, and the metal block is symmetrically fixed to the side wall of the arc-shaped plate by elastic elements. The metal block is connected in series in the motor circuit and electrically connected to the motor.

[0017] Optionally, the slide groove has two sliders slidably connected, a screw is rotatably connected to the side wall of the annular frame, and the screw is threadedly connected to the slider. A connecting rod is rotatably connected between the slider and the arc plate.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting up an adjustment mechanism to drive the rope to move back and forth at a uniform speed along the axial direction of the rope reel, the rope can be wound evenly layer by layer on the surface of the rope reel, avoiding problems such as local accumulation, tangled rope, and overlapping rope. This ensures that the rope is neatly arranged after winding, which facilitates quick and orderly release of the rope during subsequent construction operations. At the same time, it can also prevent the guide rope and traction rope from squeezing each other, causing damage to the strands and breakage, thus extending the recycling life of the guide rope and traction rope and reducing the cost of consumables for field construction.

[0020] The feedback component automatically identifies rope joints passing through the ring frame, eliminating the need for continuous manual monitoring. It can promptly and accurately output signals to stop the traction machine, preventing joints from being caught in the rope reel due to human oversight and causing damage. It also prevents damage caused by thick and thin ropes getting tangled on the same reel if the joint is not properly identified. Furthermore, it avoids premature shutdowns that lead to wasted time and work. The feedback component effectively reduces the workload of on-site construction personnel, significantly improves the accuracy of joint identification, and ensures the continuous and stable operation of the step-by-step traction and winding process.

[0021] By setting a limiting component, the rope reel and the installation shaft can be quickly connected and separated. When replacing the rope reel, it is not necessary to disassemble the entire frame. Only the locking of the limiting component needs to be released to separate the old rope reel from the installation shaft. Then, the sliding frame is moved to move the new rope reel pre-installed on the sliding frame to the position of the installation shaft. The limiting component is then used to reposition and lock it, which greatly simplifies the reel replacement operation and shortens the downtime for reel replacement. The sliding frame can install two rope reels. After the switching operation is completed, the full-load rope reel that has been switched off can be disassembled and replaced during non-operational breaks. This does not occupy the effective working time of traction and winding operations, reduces downtime waiting time at field construction sites, and effectively improves the overall efficiency of conductor erection.

Detailed Implementation

[0032] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0033] like Figures 1 to 8 As shown, an embodiment of the present invention provides an outdoor power tower conductor erection traction device, including a traction machine body 1 and a frame 2. A sliding frame 3 is slidably connected to the frame 2, and a rope reel 4 is mounted on the sliding frame 3. An installation shaft 7 is rotatably connected to the frame 2. A coaxially drivable limiting component is provided between the installation shaft 7 and the rope reel 4. The limiting component includes a conical platform 10 and an insert block 13. An adjustment mechanism is provided between the frame 2 and the rope reel 4. The adjustment mechanism is used to adjust the position of the rope winding. The adjustment mechanism includes a drive shaft 6, a ring frame 18, and a ring frame. 17. Guide groove 21 and movable block 23; The annular frame 17 is equipped with a feedback component, which is used to identify and provide feedback on the joints between ropes. The feedback component includes an arc plate 19, an arc block 20, an insulating block 26, and two metal blocks 27. This device realizes the axial reciprocating cable laying by setting an adjustment mechanism, and realizes the joint identification and triggers automatic power-off shutdown by setting a feedback component. It works with the sliding frame 3 and the limit component to complete the rapid position switching of the rope reel 4, which is suitable for the step-by-step winding of the guide rope and traction rope in tension cable laying operations.

[0034] like Figure 3 and Figure 7 As shown, the drive shaft 6 is rotatably connected to the frame 2 via the connecting shaft 25. The annular frame 18 is sleeved on the drive shaft 6 and movably connected to the drive shaft 6. A limit rod 8 is fixedly connected to the frame 2. A limit frame 22 is fixedly connected to the side wall of the annular frame 18, and the limit frame 22 is slidably connected to the limit rod 8. A guide groove 21 is formed on the outer wall of the drive shaft 6. The guide groove 21 includes two spiral grooves connected end to end. A movable block 23 is fixedly connected to the annular frame 18 and movably connected within the guide groove 21. A motor 5 is mounted on the frame 2. The output shaft of the motor 5 is coaxially fixed with the mounting shaft 7. A pulley assembly is provided between the connecting shaft 25 and the output shaft of the motor 5. 12; The pulley group 12 synchronously drives the mounting shaft 7 and the drive shaft 6 of the adjustment mechanism to ensure that the winding speed of the rope reel 4 matches the reciprocating wire laying motion of the adjustment mechanism, and the wire laying displacement and winding speed are coordinated to prevent wire laying lag and rope misalignment. The limit rod 8 constrains the rotation of the ring frame 18 to ensure that the ring frame 18 only moves axially and reciprocally, and the movement is stable and reliable. The spiral grooves connected end to end can realize the reciprocating motion of the ring frame 18 without the need for an additional reversing control mechanism. The pulley group 12 achieves mechanical forced synchronization, which has stronger anti-interference ability in the field construction site compared with electrical control synchronization, and avoids the problem of rope stacking and pressing caused by asynchronous wire laying and winding.

[0035] It should be noted that the transmission ratio of the pulley group 12 is a well-known technology in the field. Those skilled in the art can select pulleys of corresponding diameter specifications to determine the transmission ratio based on the matching requirements of the winding speed of the rope reel 4 and the winding speed of the adjusting mechanism, so as to achieve speed matching between the rope reel 4 and the drive shaft 6. This embodiment does not specifically limit the specific value of the transmission ratio of the pulley group 12. The motor 5 is connected to an external power source through wires. The external power source includes a battery for providing power to the motor 5 and a control switch for controlling its start and stop. The external power source is existing technology. The specific model and specifications of the motor 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in the field, so it will not be described in detail.

[0036] like Figure 3 , Figure 4 and Figure 6 As shown, the conical platform 10 is fixedly connected to the end of the rope reel 4, and a slot 11 is provided on the conical platform 10. A cavity is provided inside the mounting shaft 7. One end of the insert block 13 slides through the outer wall of the cavity and is adapted to the slot 11. A connecting block 14 is slidably connected inside the cavity. The other end of the insert block 13 is fixedly connected to the connecting block 14. A first spring 16 is fixedly connected between the connecting block 14 and the inner wall of the cavity. Multiple push blocks 15 are slidably connected to the outer wall of the mounting shaft 7, and the push blocks 15 are fixedly connected to the connecting blocks 14. A mounting frame 9 is rotatably connected to the sliding frame 3. The rope reel 4 The end of the device is movably connected between the mounting frame 9 and the sliding frame 3. The end of the mounting frame 9 is bolted to the sliding frame 3. The first spring 16 provides a continuous insertion preload for the insertion block 13, ensuring that the insertion block 13 is not easy to loosen under rotation. The push block 15 controls the insertion block 13 to retract synchronously, making operation simple. The conical platform 10 plays a guiding and centering role. When the rope reel 4 is connected, it can automatically align the coaxiality. The mounting frame 9 adopts a bolt-removable structure, which facilitates the disassembly and pre-assembly of the rope reel 4 on the sliding frame 3. The rope reel 4 can be assembled on the ground in advance, reducing the assembly time at the equipment station.

[0037] like Figure 4 , Figure 7 and Figure 8As shown, the annular frame 17 is fixedly connected to the bottom of the annular frame 18. The sidewalls of the annular frame 17 are symmetrically provided with sliding grooves 24. The arc-shaped plate 19 and the arc-shaped block 20 are both disposed within the annular frame 17. The arc-shaped plate 19 and the arc-shaped block 20 are slidably connected, and multiple second springs 28 are fixedly connected between the arc-shaped block 20 and the arc-shaped plate 19. The insulating block 26 is fixedly connected to the sidewall of the arc-shaped block 20. The metal block 27 is symmetrically fixed to the sidewall of the arc-shaped plate 19 by elastic elements. The metal block 27 is connected in series in the wiring of the motor 5 and is electrically connected to the motor 5. Two sliders 30 are slidably connected to the sliding grooves 24. A screw 29 is rotatably connected to the sidewall of the annular frame 17, and the screw 29 is threadedly connected to the sliders 30. A connecting rod 31 is rotatably connected to the arc plate 19; the second spring 28 ensures that the insulating block 26 and the metal block 27 are separated under normal conditions. When the joint is squeezed, the arc block 20 is pushed to compress the second spring 28, which drives the insulating block 26 to separate the metal blocks 27 on both sides to achieve circuit disconnection and stop the machine. The screw 29, slider 30 and connecting rod 31 form a bidirectional opening adjustment mechanism, which can change the enclosing diameter of the arc plate 19 to adapt to guide ropes and traction ropes of different diameters and expand the application range of the device; the threaded structure has a self-locking ability, and the position of the arc plate 19 will not shift on its own during operation after adjustment. The threads on the screw 29 are symmetrically arranged, and rotating the screw 29 can drive the two sliders 30 to move closer or further apart synchronously.

[0038] The working principle of the technical solution provided by this invention is as follows:

[0039] During operation, after the motor 5 starts, it directly drives the mounting shaft 7 to rotate. Through the engagement of the limit component's insert block 13 and slot 11, it drives the rope reel 4 to rotate synchronously for rope winding. On the other hand, the output shaft of the motor 5 drives the connecting shaft 25 and the drive shaft 6 to rotate synchronously through the pulley group 12. When the drive shaft 6 rotates, the guide groove 21 pushes the movable block 23 to reciprocate along the axial direction of the drive shaft 6 through two end-to-end connected spiral grooves. This, in turn, drives the ring frame 18 and the ring frame 17 to reciprocate synchronously in the same direction. The rope passing through the ring frame 17 reciprocates synchronously with the ring frame 17, so that the rope is evenly wound layer by layer on the surface of the rope reel 4, avoiding rope accumulation and knotting.

[0040] When the rope connector enters the annular frame 17, because the outer diameter of the connector is larger than the outer diameter of a single rope, the connector squeezes the arc-shaped block 20, pushing the arc-shaped block 20 to slide towards the arc-shaped plate 19 against the elastic force of the second spring 28. When the arc-shaped block 20 moves into place, the insulating block 26 on the side wall of the arc-shaped block 20 pushes the two metal blocks 27 to separate. At this time, the control circuit of the motor 5 is cut off, the motor 5 stops running, and the automatic identification and shutdown of the connector is completed. No manual observation and identification is required. The power-off is triggered by pure mechanical means, and no electronic components such as sensors and controllers are needed. It has high reliability in dusty and vibrating construction environments in the field and avoids the failure of electronic components to cause the connector to be missed. After the connector passes, the second spring 28 can drive the arc-shaped block 20 to automatically reset, and the metal blocks 27 re-contact and conduct, preparing for the next connector inspection.

[0041] When the rope reel 4 needs to be replaced, push the push block 15 to move axially along the mounting shaft 7. Push block 15 drives the connecting block 14 to move against the elastic force of the first spring 16, thereby driving the insert block 13 to exit from the slot 11 of the conical platform 10, releasing the lock between the mounting shaft 7 and the rope reel 4. Then, rotate the sliding frame 3 to turn the side with the new rope reel 4 to the position of the mounting shaft 7, and push the sliding frame 3 to slide so that the insert block 13 is inserted into the conical platform 10 of the new rope reel 4. During the installation process, the insert block 13 first contacts the inclined outer wall of the conical platform 10, and the insert block 13 is squeezed, which drives the connecting block 14 to compress the first spring 16. When the insert block 13... After the position of the insert block 13 is aligned with the slot 11 on the conical platform 10, the insert block 13 is no longer squeezed. Under the action of the return force of the first spring 16, the insert block 13 automatically inserts into the slot 11 of the conical platform 10, completing the coaxial locking of the new rope reel 4 and the mounting shaft 7. The equipment can then be restarted to carry out the winding operation. The entire reel replacement process does not require the overall disassembly and assembly of the frame 2, which greatly shortens the downtime. When the sliding frame 3 is used to replace the rope reel 4, the fully loaded rope reel 4 can be left on the sliding frame 3. Only the work position is switched on site. The disassembly and replacement of the fully loaded rope reel 4 can be completed offline during non-operational breaks without occupying the traction winding operation time, thus reducing the on-site downtime waiting time.

[0042] After replacing the rope reel 4, the joints between the ropes are disassembled, and the thicker rope is wound onto the rope reel 4. The adjusting screw 29 is rotated, which can drive the two sliders 30 to move synchronously towards or away from each other along the slide groove 24. The sliders 30 push the arc plate 19 to adjust its position through the connecting rod 31, thereby changing the size of the inner diameter formed by the two arc plates 19 and the arc block 20 to adapt to ropes of different diameters and meet the identification needs of guide ropes and traction ropes of different specifications.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
