Description

Technical Field

[0001] The invention relates to the technical field of wire tightening devices, and in particular to an intelligent synchronous automatic wire tightening device. Background Art

[0002] Transmission wires located on overhead lines often become loose due to their own gravity and thermal expansion and contraction due to the certain span between the poles. When the sag of the wire exceeds the specified range, the loose wire needs to be tightened. Similarly, the wire also needs to be tightened when it is installed to adjust the tightness of the wire to meet actual use needs.

[0003] At present, the commonly used method of tightening wires is mainly that construction workers manually climb up the poles to fix the traction rope on the wires and use a ratchet tightener to tighten the wires manually, or lead the wires to the ground through the traction rope and then tighten them through a tightening vehicle. The first method is not only time-consuming and labor-intensive, but also has an adverse impact on the safety of construction workers. Since the wires need to be tightened one by one, the construction efficiency is low and the construction cost is high. The second method is usually limited by the terrain and is not convenient for construction in areas with concentrated buildings. Moreover, since the wires are strung between insulators, when the ground tightening vehicle is used to tighten the wires, the large pulling force can easily damage the insulators. At the same time, these two methods are not convenient for synchronously tightening the four wires on the poles. After tightening the wires, the tightness of the wires is often judged by manually observing the verticality of the wires, which is prone to greater errors and is not conducive to precise construction.

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

[0019] The present invention provides a wire tightening machine, which is different from the traditional manual wire tightening method. It adopts an upper driving wheel and a lower driving wheel to clamp the wire. In order to improve the wire tightening effect, the contact parts of the upper driving wheel and the lower driving wheel with the wire are made of rubber material, which can also improve the insulation effect, and use independent driving motors to drive the upper driving wheel and the lower driving wheel respectively, so that the upper driving wheel and the lower driving wheel rotate in opposite directions to pull the wire to move and tighten.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figure 1-12 An intelligent synchronous automatic wire tightening device comprises a wire pole 1, a wire 4 and a wire tightening machine 5. A horizontal cross arm 2 is arranged on the top of the wire pole 1, four insulators 3 are symmetrically arranged on both sides of the cross arm 2, and a wire 4 is spanned between the corresponding insulators 3 of two adjacent wire poles 1;

[0037] The wire tensioning machine 5 includes a frame 6, a tensioning mechanism 11, a clamping mechanism 19 and a balancing assembly 22. The frame 6 is divided into an upper and lower part, and the upper and lower parts of the frame 6 are rotatably connected through a combination plate between the frames 6. Upper driving wheels 10 are symmetrically arranged on both sides of the top of the frame 6, and lower driving wheels 15 are symmetrically arranged on both sides of the bottom of the frame 6. The tensioning mechanism 11 is arranged in the upper driving wheel 10 and the lower driving wheel 15. A clamping mechanism 19 is arranged on one side of the combination plate of the frame 6, and a fixed block 20 is symmetrically arranged on the side of the bottom of the frame 6 away from the combination plate. The balancing assembly 22 is arranged between the fixed blocks 20 of two adjacent frames 6;

[0038] The tensioning mechanism 11 includes a conical block 113, a movable rod 114 and an arc block 115. The upper driving wheel 10 and the lower driving wheel 15 are both provided with a conical block 113 rotatably connected to the driving shaft. The inclined surface of the conical block 113 is slidably connected to a plurality of evenly distributed movable rods 114. The end of each movable rod 114 is fixedly connected to an arc block 115.

[0039] The balancing assembly 22 includes a balancing pole 221, a balancing sensor 222 is arranged in the middle of the balancing pole 221, a connector 223 is fixedly arranged at one end of the balancing pole 221, a sliding sleeve is arranged at the other end of the balancing pole 221, and a connector 223 is fixedly arranged at the end of the sliding sleeve. When installing the conductor 4 after the electric power system installs the electric pole 1, the conductor 4 is generally overlapped on the insulator 3 and then tightened by a tightening device to achieve the appropriate tightness of the conductor 4. The operator surveys the site and installs the tightening machine 5 on the conductor 4. The tightening machine 5 is different from the traditional manual tightening method. It uses an upper driving wheel 10 and a lower driving wheel 15 to clamp the conductor 4. In order to improve the tightening effect, the contact parts of the upper driving wheel 10 and the lower driving wheel 15 with the conductor 4 are made of rubber material, which can also improve the insulation effect and An independent driving motor 13 is used to drive the upper driving wheel 10 and the lower driving wheel 15 respectively, so that the upper driving wheel 10 and the lower driving wheel 15 rotate in opposite directions to pull the wire 4 to move and tighten. This method reduces the amount of manual operation. At the same time, the tensioning machine 5 can be automatically controlled to accurately adjust the tensioning force and reduce the safety hazards caused by manual high-altitude operation. The tensioning mechanism 11 is built into the upper driving wheel 10 and the lower driving wheel 15. The verticality of the wires 4 of different lines is different, and the verticality of the four wires 4 on the same line is also different. Therefore, after the tensioning machine 5 is installed on the conductor 4, the tensioning force needs to be adjusted according to the actual situation of the conductor 4, so as to realize the tensioning operation of the four conductors 4 synchronously, so as to save operation time and improve work efficiency. Therefore, the pressure of the upper driving wheel 10 and the lower driving wheel 15 on the conductor 4 can be adjusted by adjusting the tensioning mechanism 11, so as to realize the friction adjustment of the upper driving wheel 10 and the lower driving wheel 15 on the conductor 4, so as to provide the conductor 4 with appropriate tensioning force to complete the tensioning operation. In actual operation, a group of four conductors 4 often have different sags. It is impossible to obtain complete data only through the preliminary survey of the operator, and it is still necessary to make real-time adjustments during the tensioning operation. The balancing component 22 connects the tensioning machines 5 in pairs, and the balancing sensor 222 can monitor the balance state of each group of tensioning machines 5 in real time, judge the tensioning progress of each tensioning machine 5 by the position state of each two tensioning machines 5, and feed back the data to the communication module in real time. The communication module adjusts the tension of each tensioning machine 5 in real time through the control module to realize the automation and intelligence of the tensioning operation.

[0040] As a technical optimization solution of the present invention, a symmetrical connecting rod 7 is fixedly connected to one end of the bottom of the frame 6, and a communication box 8 is fixedly connected to the tail of the two connecting rods 7. The end of the communication box 8 is connected to a hook 9 through a wire rope. The tensioning machine 5 adopts automated operation, which saves a lot of manpower, but the preliminary preparation work still needs to be manually installed on the conductor 4. The hook 9 at the end of the tensioning device is fixedly suspended on the cross arm 2. The hook 9 can provide a reaction force to the tensioning machine 5 to limit the position of the tensioning machine 5. The communication box 8 is used for information collection, feedback, control and other functions, which can reduce manual operation. The connecting rod 7 connects the communication box 8 and the tensioning machine 5, so that the tensioning machine 5, the communication box 8 and the hook 9 are connected as a whole.

[0041] As a technical optimization solution of the present invention, a slide groove 16 is opened on the frame 6 at both ends of the driving shaft of the lower driving wheel 15, an electric slider 17 is slidably connected in the slide groove 16 on one side close to the combined plate, and a driven slider is slidably connected in the slide groove 16 on the other side, and the driving shaft of the lower driving wheel 15 is respectively connected to the middle of the electric slider 17 and the driven slider. The conductor 4 cannot be completely straightened at the initial stage of installation and during use, but is in a state with a certain sag. This sag can meet the shrinkage of the conductor 4 during thermal expansion and contraction, so the conductor 4 is in an arc state, and as the tightening operation proceeds, the curvature also decreases. Therefore, in order to ensure that the upper drive wheel 10 and the lower drive wheel 15 can fit the conductor 4 as much as possible, the upper drive wheel 10 and the lower drive wheel 15 can be misaligned. The two upper drive wheels 10 are fixed in position, and the two lower drive wheels 15 can slide synchronously along the slide groove 16 under the drive of the electric slider 17, so that the lower drive wheel 15 is misaligned with the upper drive wheel 10, and the position of the electric slider 17 is controlled by the feedback of the balance sensor 222 as the tightening operation proceeds, so as to improve the fit between the upper drive wheel 10 and the lower drive wheel 15 and the conductor 4 and improve the tightening effect.

[0042] As a technical optimization scheme of the present invention, the upper driving wheel 10 and the electric slider 17 are fixedly connected to the side wall of the combined plate, and the driving motor 13 is fixedly installed on the inner wall of the mounting frame 12. The output shaft of the driving motor 13 is fixedly connected to the driving shaft. A movable sleeve 112 is sleeved on the driving shaft. The end of the movable sleeve 112 is fixedly connected to the head end of the conical block 113. A plurality of micro electric cylinders 111 are fixedly arranged between the driving motor 13 and the head end of the movable sleeve 112. A spring 14 is sleeved on the driving shaft inside the micro electric cylinder 111. Each upper driving wheel 10 and lower driving wheel 15 is equipped with an independent driving motor 13, and the movable sleeve 112 is internally connected to the conical block 113 and externally connected to the micro-electric cylinder 111. When the control module controls the tension of the tensioning machine 5, the micro-electric cylinder 111 is actuated to push the movable sleeve 112 and the conical block 113 to slide along the driving shaft. At this time, the movable rod 114 and the arc block 115 connected to the inclined surface of the conical block 113 can slide radially along the driving wheel under the push of the conical block 113. Since the outer wall of the arc block 115 abuts against the rubber inner wall of the upper driving wheel 10 and the lower driving wheel 15, the force of the arc block 115 on the rubber wall can be increased or decreased as the movable rod 114 moves, so that the tension of the upper driving wheel 10 and the lower driving wheel 15 on the wire 4 can be changed. The spring 14 is used for soft connection and plays a certain buffering role.

[0043] As a technical optimization solution of the present invention, the clamping mechanism 19 includes a motor 192, a gear 193 and a connecting rod 194. Two sleeves 18 are symmetrically arranged at the top and bottom of the frame 6 close to the combined plate. A power box 191 is arranged between the two sleeves 18. A motor 192 is installed in the power box 191. The output shaft of the motor 192 is fixedly connected to the gear 193. A driven wheel meshing with the gear 193 is arranged below the gear 193. The gear 193 and the side wall of the driven wheel are fixedly connected to symmetrical connecting rods 194. The ends of the two connecting rods 194 are respectively clamped in the two sleeves 18. The motor 192 drives the gear 193 to rotate, and the driven wheel rotates in the opposite direction, and the two connecting rods 194 can rotate in opposite directions. Since the two connecting rods 194 are clamped in the sleeve box 18, the upper and lower parts of the frame 6 can be opened and closed during the rotation of the two connecting rods 194. During the installation of the tensioning machine 5, the motor 192 of the clamping mechanism 19 rotates, and the two connecting rods 194 approach each other. The upper and lower parts of the frame 6 are opened by the combined plate, which can facilitate the operator to send the tensioning machine 5 onto the wire 4, and wait for the tensioning machine 5 to be in position. After placement, the control motor 192 is reversed, the two connecting rods 194 move away from each other, and the upper and lower parts of the frame 6 are closed around the combined plate until the upper drive wheel 10 and the lower drive wheel 15 press the wire 4, and the installation of the tensioning machine 5 is completed. During the tensioning operation of the clamping mechanism 19, when the tension needs to be increased, the motor 192 is actuated to control the connecting rod 194 to continue to move away, pushing the upper and lower parts of the frame 6 to continue to move closer, so as to increase the pressure of the upper drive wheel 10 and the lower drive wheel 15 on the wire 4, thereby assisting the tensioning mechanism 11 to increase the tension.

[0044] As a technical optimization solution of the present invention, two fixed blocks 20 are symmetrically arranged on the side wall of the bottom of the frame 6 away from the combined board. A first slide groove 201 is provided in the fixed block 20. A first slider 21 is slidably connected to the middle of the first slide groove 201. Electric telescopic rods 224 are symmetrically arranged at the top and bottom of the first slider 21. The ends of the two electric telescopic rods 224 are respectively fixedly connected to the top and bottom of the first slide groove 201. The first slider 21 can slide up and down along the first slide groove 201 under the push of the two electric telescopic rods 224, so that the two tensioners 5 move relatively. Under the detection of the balance sensor 222, if the two tensioners 5 are found to be unbalanced in the vertical direction, the state of the tensioners 5 can be fine-tuned under the action of the first slider 21, so as to facilitate immediate adjustment and ensure the normal operation of the tensioner.

[0045] As a technical optimization solution of the present invention, a buckle 225 is fixedly provided on the outer wall of the fixing block 20, and the buckle 225 is adapted to the connector 223. The buckle 225 can be connected to a group of tensioning devices through the balance bar 221, and under the push of the electric telescopic rod 224, a group of two tensioning devices can be relatively moved in the vertical direction to maintain the relative balance of each group of tensioning devices, improve the safety and stability of the tensioning devices, and help reduce maintenance time and improve work efficiency.

[0046] As a technical optimization scheme of the present invention, second sliding grooves 23 are symmetrically provided at the top and bottom of the side of the frame 6 away from the combined plate, and buckles 25 are slidably connected in the two second sliding grooves 23. A second spring 24 is fixedly connected between the ends of the two buckles 25 and the inner walls of the second sliding grooves 23. A groove 26 is provided on the side wall of the buckle 25 away from the side of the frame 6, and an L-shaped block 29 is rotatably connected in the groove 26. A third spring 27 is fixedly connected between the side wall of the L-shaped block 29 and the inner wall of the groove 26. A handle 28 that passes through the buckle 25 is connected to the side wall of the L-shaped block 29 below the third spring 27, and a slot matching the L-shaped block 29 is provided on the side wall of the buckle 25 on the other side. The wire tensioning machine 5 is clamped on the conductor 4 and is assisted by a balancing component 22. In order to ensure safe operation, a buckle 25 is provided on one side of the frame 6. When the clamping mechanism 19 closes the frame 6, the upper and lower buckles 25 are connected, and the top of the L-shaped block 29 is pushed into the slot under the push of the third spring 27, so that the two buckles 25 are locked. After the wire tensioning operation is completed, the handle 28 is pulled to pull the L-shaped block 29 out of the slot to unlock it. The second slide groove 23 and the second spring 24 facilitate that after the two buckles 25 are connected, the upper and lower parts of the frame 6 still have room for movement, which does not affect the normal use of the clamping mechanism 19.

[0047] As a technical optimization solution of the present invention, the communication box 8 is provided with a control module, a drive module, a communication module and a battery pack. The control module is electrically connected to the micro-electric cylinder 111, the electric slider 17 and the electric telescopic rod 224. The drive module is electrically connected to the drive motor 13 and the motor 192. The communication module is electrically connected to the balance sensor 222. The battery pack supplies power to the control module, the drive module, the communication module and each electrical appliance of the tensioning machine 5 of the communication box 8. At the same time, the control module, the drive module and the communication module are wired to each other. The communication module analyzes and processes the data fed back by the balance sensor 222 and transmits it to the control module and the drive module respectively to adjust the working state of the tensioning mechanism 11, the clamping mechanism 19 and the balance assembly 22. Several parts cooperate with each other to complete the tensioning operation.

[0048] When the present invention is in use, the operator sends the tensioning device to the top of the electric pole 1, the motor 192 rotates forward, the two connecting rods 194 approach each other, and the upper and lower winding combination plates of the frame 6 are opened, so that the operator can conveniently send the tensioning machine 5 onto the wire 4. After the tensioning machine 5 is placed in place, the motor 192 is controlled to reverse, the two connecting rods 194 move away from each other, and the upper and lower winding combination plates of the frame 6 are closed until the upper driving wheel 10 and the lower driving wheel 15 press the wire 4. At this time, the two buckles 25 are connected, and the top of the L-shaped block 29 is pushed into the slot under the push of the third spring 27. After the two sets of tensioning machines 5 are installed in place, the connectors 223 at both ends of the balance bar 221 are buckled into the corresponding buckles 225 to complete the installation of the tensioning device. After the installation is completed, the tensioning device is started to automatically tighten the line. The independent driving motor 13 drives the upper driving wheel 10 and the lower driving wheel 15 respectively, so that the upper driving wheel 10 and the lower driving wheel 15 rotate in opposite directions to pull the wire 4 to move and tighten. During the tensioning process, the two lower driving wheels 15 can slide synchronously along the slide groove 16 driven by the electric slider 17, so that the lower driving wheel 1 5 is misaligned with the upper driving wheel 10, and the position of the electric slider 17 is controlled as the tensioning operation proceeds through the feedback of the balance sensor 222. The communication module analyzes and processes the data fed back by the balance sensor 222 and transmits them to the control module and the drive module respectively to adjust the working states of the tensioning mechanism 11, the clamping mechanism 19 and the balance assembly 22. When the tension needs to be increased, the micro-electric cylinder 111 is activated to push the movable sleeve 112 and the tapered block 113 to slide along the driving shaft. At this time, the movable rod 114 and the arc-shaped movable rod 114 connected to the inclined sliding surface of the tapered block 113 are The block 115 can slide radially along the driving wheel under the push of the conical block 113. Since the outer wall of the arc block 115 abuts against the rubber inner wall of the upper driving wheel 10 and the lower driving wheel 15, the action of the arc block 115 on the rubber wall can be increased with the movement of the movable rod 114, and the pulling force of the upper driving wheel 10 and the lower driving wheel 15 on the wire 4 can be increased. At the same time, the motor 192 controls the two connecting rods 194 to move away, and pushes the upper and lower parts of the frame 6 closer, so as to increase the pressure of the upper driving wheel 10 and the lower driving wheel 15 on the wire 4. The cooperation of the two can increase the pulling force.

[0049] Under the detection of the balance sensor 222, if the two tensioners 5 are found to be unbalanced in the vertical direction, the first slider 21 can slide up and down along the first slide slot 201 under the push of the two electric telescopic rods 224, so that the two tensioners 5 move relative to each other, and fine-tune the rotation state of each group of tensioners 5;

[0050] After the wire is tightened, the balance bar 221 is removed, and the handle 28 is pulled to pull the L-shaped block 29 out of the slot to unlock the buckle 25. Then the motor 192 is controlled to drive the two connecting rods 194 closer together, so that the frame 6 can be opened and removed from the wire 4.
