In some areas of the plateau region, due to the altitude drop, the drop of the transmission line is relatively large, and the microclimate and microtopography conditions of the line are also relatively harsh. Therefore, the outer layer of the overhead ground wire may break or spread, which will affect the electrical and mechanical properties of the ground wire and cause line discharge or short-circuit accidents. If not repaired in time, it will seriously endanger the safe operation of the line, and then cause serious consequences such as large-area power outages and electric shock to social personnel.

[0020] Please refer to Figures 1 to 5 simultaneously, and the preformed strand winding device for power grid construction provided by the present invention will be described. The preformed strand winding device for power grid construction includes a moving part 1, an angle adjustment part 2, a winding part 3 and an electric control part 4.

The winding part 3 forms an enclosure for the ground wire and is used to wind the preformed strand 6 around the ground wire 7 circumferentially and rotationally on the outer wall of the ground wire 7. The winding part 3 moves along the length direction of the ground wire 7 during the winding process, and the winding part 3 can be inclined; the electric control part 4 is electrically connected to the moving part 1, the angle adjustment part 2 and the winding part 3 respectively.

[0021] The pre-twisted wire 6 winding device for power grid construction provided by the present invention, compared with the prior art, can move through the setting of the moving part 1, which is convenient for winding the ground wire 7 at different positions. The angle of the winding part 3 (referring to the angle formed between the axis of the winding part 3 and the horizontal plane) can be adjusted through the setting of the angle adjusting part 2 to adapt to the installation of the ground wire 7 in different inclined states. The winding part 3 can surround the ground wire 7 and wind the pre-twisted wire 6 on the ground wire 7. By manually controlling the electric control part 4, the winding of the winding part 3 and the adjustment of the inclination angle of the angle adjusting part 2, as well as the movement of the moving part 1 can be realized, thus realizing the automatic winding of the pre-twisted wire 6 on the ground wire 7, solving the technical problems of the large construction difficulty, time-consuming and laborious, and low winding efficiency when the pre-twisted wire 6 is wound on the ground wire 7 during the repair of the ground wire 7. It has the technical effects of being able to automatically wind the pre-twisted wire 6 on the outer wall of the ground wire 7, saving time and effort, with small difficulty, being applicable to the winding of ground wires 7 with different inclination angles, and having high winding efficiency.
[0022] For the winding of the horizontally arranged ground wire 7, only the movement of the moving part 1 and the winding of the pre-twisted wire by the winding part 3 are required during the winding process; for the winding of the inclined ground wire 7, the angle adjusting part 2 needs to be used to adjust the angle of the winding part 3 and perform lifting adjustment during the winding process to adapt to the winding of the inclined ground wire 7. During the winding process, the movement of the winding part 3 should be maintained, and the axis of the winding part 3 should be parallel or coincident with the axis of the ground wire 7 (also the length direction), so that the pre-twisted wire 6 can be wound on the outer wall of the ground wire 7. The electric control part 4 in this embodiment includes a PLC controller, a control panel, a control circuit, and a plurality of control buttons, etc. The staff can realize the function of separately controlling the operation of the moving part 1, the angle adjusting part 2, and the winding part 3 by operating the plurality of control buttons, thus realizing the automatic winding of the pre-twisted wire 6. In this embodiment, the electric control part 4 is arranged at the upper end of the moving part 1 and at a position avoiding the slide rail 5.
[0023] In some embodiments, please refer to Figures 1 to 5, the moving part 1 includes a moving platform 11 and a plurality of traveling wheels 12 provided at the bottom of the moving platform 11. The plurality of traveling wheels 12 are used to support the moving platform 11. A driver and a brake (both are prior arts and not shown in the figure) are provided at the bottom of the moving platform 11. The power output end of the driver is electrically connected to at least one traveling wheel 12 and is used to drive the traveling wheel 12 to rotate, thereby driving the moving platform 11 to move. The brake is used to brake at least one traveling wheel 12; there are two slide rails 5 arranged at intervals. The length direction of the slide rails 5 is parallel to the length direction of the moving platform 11. The driver and the brake operate alternately, and both are electrically connected to the electric control unit 4 and their operations are controlled by the electric control unit 4. The top view of the moving platform 11 is rectangular, and the slide rails 5 are arranged at its upper end, or it is a kind of chute, and the depth direction of the chute extends into the moving platform 11. There are four traveling wheels 12 and they can support the movement of the moving platform 11. When it is necessary to adjust the position of the moving platform 11, the driver can be turned on at this time to drive the traveling wheels 12 to rotate, and then the moving platform 11 can be moved to any position. The moving direction during the movement can be adjusted manually. When it is not necessary to move, the traveling wheels 12 can be braked by using the brake at this time, and the moving platform 11 is braked or stopped at this time. The driver is a kind of reduction motor, which is power-connected to the traveling wheels 12. By operating on the electric control unit 4, the movement and stop of the moving platform 11 can be controlled to realize that the winding part 3 can move and stop along the axial direction of the ground wire 7.
[0024] To enable the angle adjustment part 2 to enter the slide rail 5 from the outside of the moving platform 11 and realize the detachable connection between the angle adjustment part 2 and the moving platform 11, in some embodiments, please refer to Figures 1 to 5 , an introduction groove 51 communicating with the slide rail 5 is provided at the upper end of the moving platform 11. The length direction of the introduction groove 51 is perpendicular to the length direction of the slide rail 5. The angle adjustment part 2 slides into the introduction groove 51 from the side of the moving platform 11 and slides into the slide rail 5 from the introduction groove 51 to be slidably connected to the slide rail 5. The length direction of the introduction groove 51 is along the width direction of the moving platform 11. The introduction groove 51 is perpendicular to the slide rail 5 and the two communicate with each other, enabling the angle adjustment part 2 to freely slide between the two.
[0025] In some embodiments, please refer to Figures 1 to 5, the angle adjustment part 2 includes four telescopic columns 21. The axial direction of the telescopic columns 21 is vertically arranged. The telescopic columns 21 have a vertical telescopic freedom degree. The telescopic columns 21 are electrically connected to the electric control part 4 and are telescopically controlled by the electric control part 4. The lower ends of the four telescopic columns 21 are all slidably connected to two slide rails 5. The upper ends of two of the telescopic columns 21 are respectively hinged to the bottom of one end of the winding part 3 and are respectively slidably connected to two slide rails 5. The upper ends of the other two telescopic columns 21 are respectively hinged to the bottom of the other end of the winding part 3 and are respectively slidably connected to two slide rails 5. By adjusting the telescopic lengths of the two telescopic columns 21 located at one end of the winding part 3, the angle formed between the length direction of the winding part 3 and the horizontal plane is adjusted, so that the length direction of the winding part 3 is parallel or coincident with the length direction of the ground wire 7. There are four lead-in grooves 51, which are respectively arranged corresponding to the four telescopic columns 21. One end of the lead-in groove 51 communicates with the slide rail 5, and the other end extends to the side of the moving platform 11. The four telescopic columns 21 can correspondingly slide into the four lead-in grooves 51. By pushing the four telescopic columns 21 along the width direction of the moving platform 11, the four telescopic columns 21 can be slid into the slide rails 5; then by pushing the four telescopic columns 21 along the length direction of the moving platform 11, the sliding of the four telescopic columns 21 on the two slide rails 5 can be realized. In this embodiment, if the four telescopic columns 21 are to be taken out from the moving platform 11, the four telescopic columns 21 can be respectively slid into the lead-in grooves 51, so that the telescopic columns 21 can leave the lead-in grooves 51 and the moving platform 11. Since the winding part 3 is located above the angle adjustment part 2, the winding part 3 also leaves above the moving platform 11 at this time. The four telescopic columns 21 are all electrically controlled telescopic columns 21 or telescopic rods in the prior art, and their telescopic lengths are controlled by the electric control part 4. By controlling the simultaneous telescoping of the two telescopic columns 21 located at one end or both ends of the winding part 3, the inclination angle of the winding part 3 can be adjusted to match the inclination state of the ground wire 7.
[0026] Specifically, the lower end of the telescopic column 21 is slidably connected to the slide rail 5 and the lead-in groove 51 through a circular slider.
[0027] In some embodiments, please refer to Figures 1 to 5, the winding part 3 includes a left half cylinder 31, a right half cylinder 32, a plurality of ball bearings 33, a left rotating body 34, a right rotating body 35 and a winder 36; the left half cylinder 31 is arranged in a semi-cylindrical shape, and the bottom is hinged to the upper ends of two telescopic columns 21 located on one slide rail 5; the right half cylinder 32 is arranged in a semi-cylindrical shape, and the bottom is hinged to the upper ends of two telescopic columns 21 located on another slide rail 5; the right half cylinder 32 and the left half cylinder 31 can be separated from each other and combined and docked. After docking, they can form a cylindrical structure and can surround the ground wire 7; a plurality of ball bearings 33 are evenly distributed on the inner walls of the left half cylinder 31 and the right half cylinder 32; the left rotating body 34 is arranged inside the left half cylinder 31, and the left rotating body 34 is arranged in a semi-cylindrical shape and the outer wall is in rolling connection with a plurality of ball bearings 33 located on the inner wall of the left half cylinder 31; the right rotating body 35 is arranged inside the right half cylinder 32, and the right rotating body 35 is arranged in a semi-cylindrical shape and the outer wall is in rolling connection with a plurality of ball bearings 33 located on the inner wall of the right half cylinder 32. The right rotating body 35 and the left rotating body 34 can be combined to form a cylindrical structure. The left rotating body 34 and the right rotating body 35 form an integral structure after combination and can rotate circumferentially inside the structure formed by the left half cylinder 31 and the right half cylinder 32; the winder 36 is connected to the inner wall of the left rotating body 34 or the inner wall of the right rotating body 35. The winder 36 is used to pull the preformed strand 6 and wind it circumferentially on the outer wall of the ground wire 7 as the left rotating body 34 or the right rotating body 35 rotates. The structures of the left half cylinder 31 and the right half cylinder 32 are the same, and the structures of the left rotating body 34 and the right rotating body 35 are the same. At this time, when they are mutually docked, they can both form a cylindrical structure. At this time, it can be defined as an outer cylindrical structure and an inner cylindrical structure. The inner cylindrical structure can rotate circumferentially inside the outer cylindrical structure by means of a plurality of ball bearings 33. A plurality of slideways 38 are evenly distributed along the axial direction on the outer walls of the left rotating body 34 and the right rotating body 35. A plurality of rotating seats 37 (a component for supporting the universal rotation of the ball bearings 33, which is a prior art) are arranged on the inner walls of the left half cylinder 31 and the right half cylinder 32. A plurality of ball bearings 33 are respectively rotatably connected to a plurality of rotating seats 37 one by one to realize the rotation of the ball bearings 33. And a plurality of rotating seats 37 can form a plurality of rings along the axial direction of the left half cylinder 31 and the right half cylinder 32. The plurality of rings are arranged in mutual correspondence and matching with the plurality of slideways 38. Then, the ends of the plurality of ball bearings 33 far away from the rotating seats 37 can be adaptively connected in rolling connection in the plurality of slideways 38. By arranging the plurality of slideways 38, the plurality of ball bearings 33 can be rotated, and at the same time, the inner cylindrical structure can be prevented from moving axially inside the outer cylindrical structure, so as not to affect the winding effect of the preformed strand 6 on the ground wire 7.
[0028] Before winding, the left half cylinder 31 and the right half cylinder 32 are separately arranged, and the left rotating body 34 and the right rotating body 35 are separately arranged. When winding operation is required, the four telescopic columns 21 are slidably connected to the mobile platform 11, and the left rotating body 34 and the right rotating body 35 are docked to form an enclosure around the ground wire 7, and then the left half cylinder 31 and the right half cylinder 32 are docked to form an enclosure around the inner cylinder structure. At this time, the inner cylinder structure has the circumferential rotation freedom inside the outer cylinder structure, and then by driving the rotation of the inner cylinder structure, the winder 36 can be rotated around the outer circumference of the ground wire 7, so that the pre-twisted wire 6 can be driven to be wound on the outer wall of the ground wire 7. When winding is completed, the left half cylinder 31 and the right half cylinder 32 are separated, and the four telescopic columns 21 slide in the slide rail 5 and the introduction groove 51, and then the left rotating body 34 and the right rotating body 35 are separated, and the ground wire 7 can be left at this time to continue the next pre-twisted wire winding operation.
[0029] To achieve the rotational drive of the inner cylinder structure, in some embodiments, refer to Figures 1 to 5 The ends of the left half cylinder 31 and the right half cylinder 32 are both connected to a driving motor 39, and the power output end of the driving motor 39 is connected to a roller 391. The outer wall of the roller 391 is connected to the outer wall of the left rotating body 34 or the outer wall of the right rotating body 35. The driving motor 39 is used to drive the left rotating body 34 and the right rotating body 35 to rotate circumferentially at the same time. The driving motor 39 is electrically connected to the electronic control unit 4 and its operation is controlled by the electronic control unit 4. The driving motor 39 is arranged at the end of the outer cylinder structure. A plurality of driving motors 39 can be arranged along the circumference of the outer cylinder structure, which can simultaneously drive the inner cylinder structure to rotate circumferentially, thereby causing the winding part 3 to rotate at the same time. Since the winding part 3 can pull the pre-twisted wire 6, the pre-twisted wire 6 may be wound around the ground wire 7. The driving motor 39 in this embodiment is a reduction motor that can rotate at a uniform speed and wind the pre-twisted wire 6 uniformly and at a uniform speed around the ground wire 7. In this embodiment, the outer wall of the roller 391 is in rolling contact with the outer wall of the left-rotating body 34 or the outer wall of the right-rotating body 35. In this embodiment, the length of the inner cylinder structure is greater than the length of the outer cylinder structure. Gears can be set on the outer circumferential wall of the inner cylinder structure, that is, the outer wall of the left-rotating body 34 or the outer wall of the right-rotating body 35 is provided with half a gear, and the two half gears can be connected to each other to form an integral gear. A small gear is sleeved on the outer wall of the roller 391, and the small gear can be meshed and connected with the integral gear, so that the driving motor 39 can drive the inner cylinder to rotate through gear transmission, and then the pre-twisted wire 6 can be wound around the ground wire 7.
[0030] To achieve the docking combination of the left-hand rotating body 34 and the right-hand rotating body 35, in some embodiments, refer to Figures 1 to 5, connecting plates 310 are connected to the inner walls of both the left rotating body 34 and the right rotating body 35. A locking member is inserted through the connecting plate 310. The locking member is used to fixedly connect the left rotating body 34 and the right rotating body 35 to form an integral structure. The winder 36 is arranged to avoid the connecting plate 310 and the locking member. A locking member (such as a bolt, etc.) is inserted through one of the two adjacent connecting plates 310. By passing the locking member through the two adjacent connecting plates 310, the two connecting plates 310 can be fixedly connected. At this time, the left rotating body 34 and the right rotating body 35 can form an integral body. When disassembly is required, only the locking member needs to be disassembled. For ease of installation and disassembly, the connecting plate 310 is arranged at the end position close to the inner cylinder structure, with two sets arranged symmetrically at one end, a total of four sets.
[0031] Preferably, on the outer walls of the left half cylinder 31 and the right half cylinder 32, they are also fixed by the mutual cooperation and connection of a plurality of connecting plates 310 and a plurality of locking members. After such connection, the structural strength of the two after connection can be increased, preventing cracking during the winding process of the preformed strand 6 and affecting the winding effect.
[0032] To adjust the position of the winder 36 to facilitate starting to wind the preformed strand 6 from different positions on the ground wire 7. In some embodiments, please refer to Figures 1 to 5 , curved rails 311 are circumferentially arranged on the inner walls of both the left rotating body 34 and the right rotating body 35. The winder 36 is slidably connected to the curved rail 311 and can be limited on the curved rail 311. In this embodiment, there are four sets of curved rails 311, and every two sets of curved rails 311 are arranged at intervals. By slidably connecting the winder 36 to the curved rail 311, the position of the winder 36 can be adjusted to facilitate starting to wind the preformed strand 6 from different positions on the ground wire 7.
[0033] Multiple sets of curved rails 311 can also be arranged along the axial direction of the inner cylinder structure. Before the inner cylinder structure is in a separated state, the preformed strand 6 needs to pass through the winding part 3, then lock the position of the winding part 3 on the curved rail 311, and then assemble the inner cylinder structure.
[0034] In some embodiments, please refer to Figures 1 to 5The winder 36 includes a slider 3111 slidably connected to the curved rail 311 and a hook 3112 connected to the slider 3111. The hook 3112 is used to allow the pre-twisted wire 6 to pass through and guide the pre-twisted wire 6 to be wound around the outer wall of the ground wire 7. A top screw is passed through the slider 3111. By screwing the top screw, the inner end of the top screw can abut against the curved rail 311, so that the slider 3111 can be limited on the curved rail 311, and the position of the winding part 3 is fixed. The hook 3112 is equivalent to a ring, and the outer end of the ring is fixedly connected to the slider 3111. The pre-twisted wire 6 passes through the inside of the ring. With the circumferential rotation of the inner cylinder structure and the movement of the moving part 1, the pre-twisted wire can be gradually wound around the ground wire 7. The winding part 3 plays a role in guiding the winding direction and winding position of the pre-twisted wire.
[0035] In order to achieve that the pre-twisted wire can be arranged close to the outer wall of the ground wire 7, in some embodiments, refer to Figures 1 to 5 The curved rail 311 avoids the position of the winder 36 and is slidably connected with a clamping member 312. One end of the clamping member 312 is slidably connected to the curved rail 311 and the other end is provided with a roller 313. The clamping member 312 has the freedom of extension and contraction along its axial direction. The axial direction of the clamping member 312 is perpendicular to the length direction of the ground wire 7. The clamping member 312 is used to push the roller 313 to move, so that the roller 313 rolls against the pre-twisted wire 6 and the pre-twisted wire 6 is arranged close to the outer wall of the ground wire 7. The clamping member 312 is electrically connected to the electric control unit 4 and its operation is controlled by the electric control unit 4. The clamping member 312 is an electrically controlled telescopic rod, which can realize extension and contraction and push the roller 313. Then, during the winding process, the roller 313 is rolled against the pre-twisted wire, so that the pre-twisted wire to be wound on the ground wire 7 can be close to the outer wall of the ground wire 7, so that the pre-twisted wire can be operated according to the winding standards or requirements to meet the operation requirements. Specifically, the wire harness connected to the pressing member 312 can be led out from the end of the outer cylinder structure to achieve electrical connection with the electric control unit 4 .
