Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to an adjustable electric-driven double-wheel tension machine. Background Art

[0002] The electric-driven double-wheel tension machine is a tension machine driven by a motor. It is mainly used in the tensioning operation of transmission lines to provide stable tension for the conductors and ensure that the conductors do not come into contact with the ground or other obstacles during the installation process, thereby protecting the surface quality of the conductors and meeting the construction requirements. The working principle of the electric-driven double-wheel tension machine mainly depends on the driving force of the motor. The motor drives the tension wheel to rotate through the transmission system. When the conductor is pulled by external force, the tension wheel will rotate and generate stable tension. This tension can be precisely controlled by adjusting the output power of the motor or the reduction ratio of the transmission system.

[0003] When laying cables on electric towers, tension machines and traction machines are required. Since the distribution locations of electric towers in different sites are different, the laying processes are different. Traditional laying processes are mostly divided into two types, one of which is a combination of a traction field and a tension field, and the other is a combination of a tension field and two traction fields. The process of combining a tension field and a traction field is suitable for areas where electric towers are evenly distributed, and the distances between adjacent electric towers are not much different. In actual configuration, the traction field and the tension field are respectively set near the first and last electric towers. This process uses at least one cable, and all cables are transported in one direction. The process of combining one tension field and two traction fields is suitable for a site with two groups of towers with large intervals, but the towers in each group of towers are evenly distributed. In actual configuration, the tension field is located between the two groups of towers, and the two traction fields are respectively located at the tail towers in the two groups of towers. This process uses at least two cables, and the two cables are transported in opposite directions. The traditional tension machine can only be applied to one of the erection processes. If the erection process is changed, the number of tension machines needs to be increased, which will increase the corresponding cost. Therefore, it is necessary to provide an adjustable electric-driven two-wheel tension machine to solve the above problems. Summary of the invention

A second synchronous transmission member is arranged between the third rotating wheel 4 and the fourth rotating wheel 5. A mounting frame 6, a spline sleeve 7 and a driving assembly are arranged beside the first rotating wheel 2. The driving assembly includes a motor 8, a main shaft 9, a rotating sleeve 10 and a reversing mechanism. The motor 8 is fixedly connected to the mounting frame 6. The main shaft 9 rotates on the mounting frame 6, and the main shaft 9 is coaxial with the first rotating wheel 2. The rotating sleeve 10 rotates coaxially outside the main shaft 9. The reversing mechanism connects the main shaft 9 and the rotating sleeve 10 with the motor 8. The main shaft 9 and the rotating sleeve 10 rotate in opposite directions. A first spline groove 11 (such as Fig.13 As shown in FIG. 1 , one end of the main shaft 9 passes through the first spline groove 11 and is coaxially connected to the third runner 4. The spline sleeve 7 is coaxially sleeved on the main shaft 9 (as shown in FIG. 1 ). Fig.11As shown), the spline sleeve 7 is inserted into the No. 1 spline groove 11, and the two ends of the spline sleeve 7 are provided with a No. 1 connecting piece and a No. 2 connecting piece corresponding to the main shaft 9 and the rotating sleeve 10 respectively.

[0035] When laying cables on electric towers, tension machines and traction machines are required. Since the distribution locations of electric towers in different sites are different, the laying processes are different. Traditional laying processes are mostly divided into two types, one of which is a combination of a traction field and a tension field, and the other is a combination of a tension field and two traction fields. The process of combining a tension field and a traction field is suitable for areas where electric towers are evenly distributed, and the distances between adjacent electric towers are not much different. In actual configuration, the traction field and the tension field are respectively set near the first and last electric towers. This process uses at least one cable, and all cables are transported in one direction. A tension field The process combined with two traction fields is suitable for sites with two groups of electric towers with large intervals, but the electric towers in each group of electric towers are evenly distributed. In actual configuration, the tension field is set between the two groups of electric towers, and the two traction fields are respectively set at the tail towers in the two groups of electric towers. This process uses at least two cables, and the two cables are transported in opposite directions. The traditional tension machine can only be applied to one of the erection processes. If the erection process is changed, the number of tension machines needs to be increased. The tension machine with adjustment function of this device can be applied to two erection processes at the same time, and only one device is needed to meet the needs of two erection processes.

[0036] Regardless of which erection process is used, when laying the cable, it is necessary to first connect the wire to the tower (not shown in the figure), the wire passes through all the towers, and the two ends of the wire are connected to the output end of the traction machine and one end of the cable respectively. When the erection process is a combination of a traction field and a tension field, the spline sleeve 7 is dialed, and the spline sleeve 7 is connected to the main shaft 9 through the No. 1 connecting piece. At this time, the spline sleeve 7 is not connected to the rotating sleeve 10, and then the cable is wound on the No. 1 rotating wheel 2 and the No. 2 rotating wheel 3, as shown in FIG. Figure 1As shown, the cable led out from the cable drum (not shown in the figure) is wound around the No. 1 runner 2 from the top and then wound around the No. 2 runner 3 from the bottom. Finally, the cable is led from the top of the No. 2 runner 3 to the nearby power tower. After that, the device and the traction machine work synchronously. The specific working process is as follows: start the motor 8, and the motor 8 drives the main shaft 9 and the rotating sleeve 10 to rotate synchronously in the opposite direction. Since the spline sleeve 7 and the main shaft 9 are connected at this time, the direction of the No. 1 runner 2 is the same as the direction of the No. 3 runner 4. When the No. 1 runner 2 and the No. 3 runner 4 rotate, the No. 2 runner 3 and the No. 4 runner 5 will be driven to rotate through the action of the No. 1 synchronous transmission member and the No. 2 synchronous transmission member, wherein the No. 2 runner 3 The steering is always the same as that of the No. 1 wheel 2, and the steering of the No. 4 wheel 5 is always the same as that of the No. 3 wheel 4. Finally, the No. 1 wheel 2 and the No. 2 wheel 3 that rotate synchronously and in the same direction cooperate with the traction machine to transport the cable. Among them, the motor 8 used in this device is a reduction motor 8, so the rotation speeds of the No. 1 wheel 2, the No. 2 wheel 3, the No. 3 wheel 4 and the No. 4 wheel 5 are all slow. The cable ensures its own tension through double winding. When it is necessary to lay two cables to the power tower at the same time, another cable can be wound around the No. 3 wheel 4 and the No. 4 wheel 5. The winding method is consistent with that of the No. 1 wheel 2 and the No. 2 wheel 3, and finally it is realized that two cables are continuously transported to the power tower at the same time.

[0037] When the erection process is a process combining one tension field and two traction fields, the spline sleeve 7 is dialed, and the spline sleeve 7 is connected to the rotating sleeve 10 through the No. 2 connecting piece. At this time, the spline sleeve 7 is not connected to the main shaft 9. Then, one cable is wound around the No. 1 runner 2 and the No. 2 runner 3, and another cable is wound around the No. 3 runner 4 and the No. 4 runner 5. The two traction fields have two traction machines. Then, the device works synchronously with the two traction machines. The specific working process is as follows: start the motor 8, and the motor 8 drives the main shaft 9 and the rotating sleeve 10 to rotate synchronously in the opposite direction. Since the spline sleeve 7 and the rotating sleeve 10 are connected at this time, the direction of rotation of the No. 1 runner 2 is opposite to the direction of rotation of the No. 3 runner 4, so that the conveying directions of the two cables are opposite. Then, through the cooperation of the traction machines in the two traction fields, the reverse conveying of the two cables is finally realized. When two cables need to be erected to the tower at the same time, two sets of the device can be put into the current tension field.

[0038] In order to show how the first wheel 2, the second wheel 3, the third wheel 4 and the fourth wheel 5 are rotatably connected to the support frame 1, the following features are set:

[0039] Both sides of the No. 1 wheel 2, the No. 2 wheel 3, the No. 3 wheel 4 and the No. 4 wheel 5 are formed with convex rings 12, and four groups of brackets 13 corresponding to the No. 1 wheel 2, the No. 2 wheel 3, the No. 3 wheel 4 and the No. 4 wheel 5 are fixed on the support frame 1, and two symmetrical semicircular frames 14 are formed on each group of brackets 13, and a semicircular groove 15 is opened in each semicircular frame 14, and each convex ring 12 is embedded in the corresponding semicircular groove 15.

[0040] The installation method of the No. 1 wheel 2, the No. 2 wheel 3, the No. 3 wheel 4 and the No. 4 wheel 5 is the same. Taking the No. 1 wheel 2 as an example, the No. 1 wheel 2 is downwardly installed on the corresponding bracket 13. During this process, the convex rings 12 provided on both sides of the No. 1 wheel 2 will be respectively embedded downward in the semicircular grooves 15 in the two semicircular frames 14. At this time, the No. 1 wheel 2 is supported by the bracket 13, and the No. 1 wheel 2 realizes its own rotation through the convex rings 12 embedded in the semicircular grooves 15. At the same time, the No. 1 wheel 2 is restricted from deviating left and right by the two semicircular frames 14.

[0041] In order to show the specific structure of the reversing mechanism, the following features are set:

[0042] A rectangular frame 16 is fixedly provided on the mounting frame 6, and a No. 1 collar 17 and a No. 2 collar 18 are respectively formed on both sides of the rectangular frame 16. The caliber of the No. 1 collar 17 is larger than that of the No. 2 collar 18. The main shaft 9 passes through the No. 1 collar 17 horizontally, and one end of the main shaft 9 is rotatably connected to the No. 2 collar 18, and one end of the rotating sleeve 10 is rotatably connected to the No. 1 collar 17. The reversing mechanism includes a No. 1 bevel gear 19, a No. 2 bevel gear 20 and a No. 3 bevel gear 21. The No. 1 bevel gear 19 and the No. 2 bevel gear 20 are symmetrically fixedly connected to the main shaft 9 and the rotating sleeve 10 respectively, and the No. 3 bevel gear 21 is arranged between the No. 1 bevel gear 19 and the No. 2 bevel gear 20. The motor 8 is horizontal, and the No. 3 bevel gear 21 is coaxially fixedly connected to the output end of the motor 8, and the No. 1 bevel gear 19 and the No. 2 bevel gear 20 are both meshed with the No. 3 bevel gear 21.

[0043] When the motor 8 is started, the motor 8 will drive the No. 3 bevel gear 21 to rotate. Since the No. 1 bevel gear 19 and the No. 2 bevel gear 20 are both meshed with the No. 3 bevel gear 21, the No. 1 bevel gear 19 and the No. 2 bevel gear 20 will be synchronously driven to rotate by the No. 3 bevel gear 21, and the No. 1 bevel gear 19 and the No. 2 bevel gear 20 have opposite directions, so that the main shaft 9 and the rotating sleeve 10 will rotate synchronously and in the opposite direction.

[0044] In order to improve the rotation stability of the spline sleeve 7, the following features are provided:

[0045] A stabilizing seat fixedly connected to the support frame 1 is provided on the side of the No. 1 rotating wheel 2, and the stabilizing seat includes a vertical frame 22, a mounting seat 23 and an inner groove sleeve 24. The vertical frame 22 is fixed on the support frame 1, and the mounting seat 23 is fixed to the top of the vertical frame 22. The inner groove sleeve 24 rotates in the mounting seat 23. The inner groove sleeve 24 is coaxial with the spline sleeve 7, and a No. 2 spline groove 25 is provided on the inner groove sleeve 24 for the spline sleeve 7 to pass horizontally.

[0046] When one end of the main shaft 9 is connected to the No. 2 sleeve 18 for rotation, the other end of the main shaft 9 passes through the inner sleeve 24 through the No. 2 spline groove 25 and then passes through the entire No. 1 runner 2 through the No. 1 spline groove 11. Finally, the other end of the main shaft 9 is coaxially fixedly connected to the No. 3 runner 4. When the spline sleeve 7 is inserted into the inner sleeve 24 through the No. 2 spline groove 25, the spline sleeve 7 will be sleeved outside the main shaft 9, and the inner sleeve 24 will rotate in the mounting seat 23. The inner sleeve 24 can only rotate and cannot translate along its own axial direction. Then, when the spline sleeve 7 rotates, the spline sleeve 7 will drive the inner sleeve 24 to rotate through the No. 2 spline groove 25, and the inner sleeve 24 will improve the rotation stability of the spline sleeve 7. When the spline sleeve 7 is turned, the spline sleeve 7 will translate along its own axial direction in the inner sleeve 24 through the action of the No. 2 spline groove 25, and in the process of the translation of the spline sleeve 7, the translation stability of the spline sleeve 7 is improved by the inner sleeve 24.

[0047] In order to show the specific structure of connector No. 1, the following features are set:

[0048] The No. 1 connecting member includes a No. 1 gear ring 26 and a No. 2 gear ring 27. The No. 1 gear ring 26 is coaxially fixedly connected to one end of the spline sleeve 7 close to the No. 3 rotating wheel 4. The No. 2 gear ring 27 is coaxially fixedly connected to the main shaft 9. The No. 2 gear ring 27 is located between the No. 1 rotating wheel 2 and the No. 3 rotating wheel 4, and the No. 1 gear ring 26 and the No. 2 gear ring 27 can mesh with each other.

[0049] When a traction field and a tension field are combined in the erection process, the spline sleeve 7 is pushed toward the third rotating wheel 4. During this process, the first gear ring 26 arranged at one end of the spline sleeve 7 will move toward the second gear ring 27 fixed on the main shaft 9, and the first gear ring 26 and the second gear ring 27 are meshed by rotating the spline sleeve 7. After the first gear ring 26 and the second gear ring 27 are meshed, a clamp 44 (such as a clamp 44 for limiting the reverse translation of the spline sleeve 7) is fixed to the main shaft 9. Figure 6 As shown), when the main shaft 9 rotates, the main shaft 9 will drive the spline sleeve 7 to rotate, and the main shaft 9 and the spline sleeve 7 have the same direction of rotation, and finally the first rotating wheel 2 and the third rotating wheel 4 will rotate in the same direction.

[0050] In order to show the specific structure of the No. 2 connector, the following features are set:

[0051] The second connecting member includes a first connecting plate 28 and a second connecting plate 29. The first connecting plate 28 is coaxially fixed to one end of the spline sleeve 7 close to the rotating sleeve 10, and the second connecting plate 29 is coaxially fixed to the rotating sleeve 10. The peripheral wall of the first connecting plate 28 is formed with a plurality of first lugs 30 (such as Figure 2 As shown in the figure, a plurality of No. 2 lugs 31 are formed on the peripheral wall of the No. 2 connecting disk 29 and are evenly distributed along the circumferential direction of the No. 2 connecting disk 29 , and each No. 1 lug 30 corresponds to the No. 2 lug 31 .

[0052] When carrying out a construction process combining a tension field with two traction fields, the clamp 44 fixed on the main shaft 9 is removed, and then the spline sleeve 7 is moved toward the rotating sleeve 10. During this process, the No. 1 gear ring 26 is separated from the No. 2 gear ring 27, and the No. 1 connecting plate 28 will translate toward the No. 2 connecting plate 29. When the No. 1 connecting plate 28 and the No. 2 connecting plate 29 are fitted together, the No. 1 lug 30 and the No. 2 lug 31 are connected by bolts (not shown in the figure), and finally the No. 1 connecting plate 28 and the No. 2 connecting plate 29 are fixedly connected. When the main shaft 9 rotates, the rotating sleeve 10 will drive the spline sleeve 7 to rotate. Since the rotating sleeve 10 and the main shaft 9 have opposite directions, the No. 1 runner 2 and the No. 3 runner 4 will finally rotate in the opposite direction.

[0053] In order to show the specific structure of the No. 1 synchronous transmission part, the following features are set:

[0054] The No. 1 synchronous transmission member includes a No. 1 synchronous belt 32 and two No. 1 synchronous wheels 33. A No. 1 shaft seat 34 fixedly connected to the support frame 1 is provided on the side of the No. 2 rotating wheel 3. A No. 1 rotating shaft 35 horizontally passing through the No. 1 shaft seat 34 is coaxially fixed to the No. 2 rotating wheel 3. One of the No. 1 synchronous wheels 33 is coaxially connected to the No. 1 rotating shaft 35, and the other No. 1 synchronous wheel 33 is coaxially connected to the inner groove sleeve 24. The No. 1 synchronous belt 32 is sleeved on the two No. 1 synchronous wheels 33.

[0055] When the spline sleeve 7 rotates, the spline sleeve 7 will drive the inner sleeve 24 to rotate through the second spline groove 25, so that the inner sleeve 24 will drive the corresponding first synchronous wheel 33 to rotate. Then, through the transmission action of the first synchronous belt 32, the second rotating wheel 3 will eventually be driven to rotate synchronously and in the same direction as the first rotating wheel 2.

[0056] In order to show the specific structure of the second synchronous transmission part, the following features are set:

[0057] The No. 2 synchronous transmission member includes a No. 2 synchronous belt 36 and two No. 2 synchronous wheels 37. A No. 2 shaft seat 38 and a No. 3 shaft seat 39 fixedly connected to the support frame 1 are respectively arranged on the sides of the No. 3 rotating wheel 4 and the No. 4 rotating wheel 5. A No. 2 rotating shaft 40 horizontally passing through the No. 2 shaft seat 38 is coaxially fixedly connected to one end of the main shaft 9. A No. 3 rotating shaft 41 horizontally passing through the No. 3 shaft seat 39 is coaxially fixedly connected to the No. 4 rotating wheel 5. The two No. 2 synchronous wheels 37 are coaxially fixedly connected to the No. 2 rotating shaft 40 and the No. 3 rotating shaft 41 respectively. The No. 2 synchronous belt 36 is sleeved on the two No. 2 synchronous wheels 37.

[0058] When the main shaft 9 drives the third wheel 4 to rotate, the third wheel 4 drives the corresponding second synchronous wheel 37 to rotate through the second shaft 40, and then through the action of the second synchronous belt 36, the fourth wheel 5 will be driven to rotate synchronously and in the same direction as the third wheel 4.

[0059] In order to prevent the cable from slipping on the first wheel 2, the second wheel 3, the third wheel 4 and the fourth wheel 5, the following features are provided:

[0060] A rubber ring 42 is fixedly provided on the peripheral wall of the first reel 2 , the second reel 3 , the third reel 4 and the fourth reel 5 . The rubber ring 42 is provided with a plurality of groups of equally spaced line grooves 43 .

[0061] Taking the first reel 2 as an example, when the cable is wound around the first reel 2, the cable will be wound in the corresponding wire groove 43, and the wire groove 43 is used to prevent the cable from deviating left and right on the first reel 2, and the friction between the cable and the first reel 2 is increased by the rubber ring 42 to prevent the cable and the first reel 2 from slipping.

[0062] Working principle: When the erection process is a combination of a traction field and a tension field, the spline sleeve 7 is turned, and the spline sleeve 7 is connected to the main shaft 9 through the No. 1 connecting piece. At this time, the spline sleeve 7 is not connected to the rotating sleeve 10, and then the cable is wound around the No. 1 rotating wheel 2 and the No. 2 rotating wheel 3, as shown in FIG. Figure 1 As shown, the cable led out from the cable drum (not shown in the figure) is wound around the No. 1 runner 2 from the top and then wound around the No. 2 runner 3 from the bottom. Finally, the cable is led from the top of the No. 2 runner 3 to the nearby power tower. After that, the device and the traction machine work synchronously. The specific working process is as follows: start the motor 8, and the motor 8 drives the main shaft 9 and the rotating sleeve 10 to rotate synchronously in the opposite direction. Since the spline sleeve 7 and the main shaft 9 are connected at this time, the direction of the No. 1 runner 2 is the same as the direction of the No. 3 runner 4. When the No. 1 runner 2 and the No. 3 runner 4 rotate, the No. 2 runner 3 and the No. 4 runner 5 will be driven to rotate through the action of the No. 1 synchronous transmission member and the No. 2 synchronous transmission member, wherein the No. 2 runner 3 The steering is always the same as that of the No. 1 wheel 2, and the steering of the No. 4 wheel 5 is always the same as that of the No. 3 wheel 4. Finally, the No. 1 wheel 2 and the No. 2 wheel 3 that rotate synchronously and in the same direction cooperate with the traction machine to transport the cable. Among them, the motor 8 used in this device is a reduction motor 8, so the rotation speeds of the No. 1 wheel 2, the No. 2 wheel 3, the No. 3 wheel 4 and the No. 4 wheel 5 are all slow. The cable ensures its own tension through double winding. When it is necessary to lay two cables to the power tower at the same time, another cable can be wound around the No. 3 wheel 4 and the No. 4 wheel 5. The winding method is consistent with that of the No. 1 wheel 2 and the No. 2 wheel 3, and finally it is realized that two cables are continuously transported to the power tower at the same time.

[0063] When the erection process is a process combining one tension field and two traction fields, the spline sleeve 7 is dialed, and the spline sleeve 7 is connected to the rotating sleeve 10 through the No. 2 connecting piece. At this time, the spline sleeve 7 is not connected to the main shaft 9. Then, one cable is wound around the No. 1 runner 2 and the No. 2 runner 3, and another cable is wound around the No. 3 runner 4 and the No. 4 runner 5. The two traction fields have two traction machines. Then, the device works synchronously with the two traction machines. The specific working process is as follows: start the motor 8, and the motor 8 drives the main shaft 9 and the rotating sleeve 10 to rotate synchronously in the opposite direction. Since the spline sleeve 7 and the rotating sleeve 10 are connected at this time, the direction of rotation of the No. 1 runner 2 is opposite to the direction of rotation of the No. 3 runner 4, so that the conveying directions of the two cables are opposite. Then, through the cooperation of the traction machines in the two traction fields, the reverse conveying of the two cables is finally realized. When two cables need to be erected to the tower at the same time, two sets of the device can be put into the current tension field.
