Abstract
Description
Technical Field
[0001] The present invention belongs to the field of transmission and distribution infrastructure construction, and specifically relates to a fine-tuning device for tightening overhead lines. Background Art
[0002] With the rapid growth of the national economy, the demand for electricity is increasing day by day, and the construction of overhead transmission lines has become particularly important. For example Figure 1 , during the erection of overhead transmission lines, a wire tightener is an essential tool. By reducing the length of the overhead line between two erected tower poles, the transmission line of this section is tightened, so as to ensure that the transmission line meets the specified tension requirements, thereby ensuring the safe and effective operation of the transmission line. Specifically, if the tension of the transmission line is too small, that is, the erection of the transmission line is too loose, it will lead to too large a sag value of the transmission line, resulting in insufficient safety distance between the transmission line and the ground or obstacles below, and affecting the mechanical and electrical properties of the wire. On the contrary, if the sag value is too small, it will lead to too large a tension of the transmission line, prone to short-circuit accidents, and increasing the risk of insulator damage.
[0003] Currently, the existing wire tightening method is carried out in two stages. In the first stage, the operator uses a tractor to perform a preliminary wire tightening operation on the overhead transmission line, and makes the sag value of the transmission line roughly near the set sag value; in the second stage, the operator works through multi-person cooperation. One person manually tightens the transmission line through a ratchet tightener, and the others observe the sag situation of the overhead transmission line, and multiple people keep communicating during the work process, and finally achieve a wire tightening operation with relatively high precision for the overhead transmission line. Here, the wire tightening precision refers to the allowable degree of the tightening length error of the transmission line. A low precision corresponds to a larger allowable error, and a high precision corresponds to a smaller allowable error. For example, when it is expected to tighten a transmission line of a predetermined length, if the length of the actually tightened transmission line deviates less from the predetermined length, the wire tightening precision is higher, and vice versa, the wire tightening precision is lower.
[0004] The defect of the above implementation is that when performing wire tightening with relatively high precision, it relies too much on the cooperation of multiple people, which not only requires more labor costs, but also due to the fatigue factor of people, it is difficult to ensure the wire tightening precision and efficiency during long-term operations, and there are also great safety risks for the operator's high-altitude operations. Summary of the Invention
[0005] In view of the deficiencies of the prior art, the present invention provides a fine-tuning device for tightening overhead lines, which can not only reduce the participation of operators, but also accurately control the wire tightening precision.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] An overhead line tightening and fine-tuning device, characterized in that it comprises: a fixing member connected to a cross arm or a pole tower, and a winding unit fixedly connected to the fixing member. Among them, the winding unit includes a winding cylinder, a winding cable and a rotary encoder. One end of the winding cable is fixed on the winding cylinder, and the other end is traction-coupled with the overhead line. The rotary encoder is rotationally coupled with the winding cylinder. When the winding cylinder rotates to wind and store the winding cable, the overhead line is tightened accordingly.
[0008] Preferably, the present invention further includes a tension sensor, and the other end of the winding cable is traction-coupled with the overhead line through the tension sensor.
[0009] Furthermore, the winding unit further includes a winding pulley group, which includes a winding fixed pulley and a winding movable pulley. The winding cable simultaneously wraps around the winding fixed pulley and the winding movable pulley.
[0010] Still further, the winding pulley group further includes a movable pulley bracket. The winding movable pulley is rotatably arranged on the movable pulley bracket. The tension sensor is detachably arranged at one end of the movable pulley bracket, and this end is used as the wire-grabbing end. A wire anti-detachment entity is also detachably arranged at the wire-grabbing end. The wire anti-detachment entity is located near the winding movable pulley and is used to prevent the winding movable pulley from detaching from the cable.
[0011] Still further, the present invention further includes a synchronous wire arranging assembly located near the winding cylinder. The synchronous wire arranging assembly includes a wire arranging guide rail, a wire arranging slider and a synchronous driving member. The wire arranging guide rail extends in the same direction as the rotating shaft of the winding cylinder. The wire arranging slider is matched with the wire arranging guide rail and can move linearly. The synchronous driving member is coupled with the wire arranging slider and is used to drive the wire arranging slider to move. The wire arranging slider is located between the winding cylinder and the winding pulley group, and a wire passing through hole is formed on the wire arranging slider. The winding cable passes through the wire passing through hole.
[0012] Still further, the synchronous driving member is a shaft rod parallel to the winding cylinder, and both the synchronous driving member and the winding cylinder have mutually meshing synchronous coupling gears. A spiral cam groove extending axially is formed on the peripheral surface of the driving member. The wire arranging slider has a driving protrusion matched with the spiral cam groove. When the winding cylinder rotates, it drives the synchronous driving member to rotate, and thus the spiral cam groove drives the wire arranging slider to move on the wire arranging guide rail.
[0013] Still further, the wire arranging slider includes a slider main body and a driving protrusion. The driving protrusion is a mating roller rotatable relative to the slider main body. When the spiral cam groove drives the wire arranging slider to move on the wire arranging guide rail, the mating roller rolls in contact with the inner wall of the spiral cam groove.
[0014] Still further, the synchronous driving member also has an end sealing entity located at the end of the synchronous driving member, and the end sealing entity is detachably arranged. The end sealing entity is used to close or open the spiral cam groove.
[0015] Preferably, the present invention further includes a base, on which the fixing member, the winding unit, and the rotary encoder are provided. The main driving assembly includes a main driving motor and a main driving gear. The output shaft of the main driving motor is parallel to the winding cylinder. The driving gear is provided on the output shaft of the main driving motor. The winding cylinder has a driven gear that meshes with the driving gear. When the driving motor drives the driving gear to rotate, the winding cylinder rotates drivenly through the driven gear.
[0016] Furthermore, the present invention further includes a portable terminal, which is signal-connected to the main driving motor. The portable terminal drives the main driving motor to act through an input instruction.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] 1. Since the overhead line tensioning and fine-tuning device of the present invention includes a fixing member and a winding unit that are fixedly connected to each other, the fixing member is connected to the cross arm or the pole tower, the winding unit includes a winding cylinder, a winding cable, and a rotary encoder. One end of the winding cable is fixed on the winding cylinder, and the other end is traction-coupled with the overhead line. The rotary encoder is rotation-coupled with the winding cylinder. When the winding cylinder winds and stores the winding cable through rotation, the overhead line is tightened. During operation, the winding cylinder traction the overhead line through the winding cable, so that the overhead line is wound on the winding cylinder, thereby feeding the overhead line. And the number of rotation turns of the winding cylinder can be obtained through the rotary encoder, so as to obtain a relatively accurate tensioning distance. Therefore, the present invention can not only reduce the participation of operators, but also accurately control the tensioning accuracy.
[0019] 2. Since the present invention further includes a tension sensor, the other end of the winding cable is traction-coupled with the overhead line through the tension sensor. Therefore, in addition to directly controlling the accuracy of the tensioning distance, the present invention can also obtain the tension data of the overhead line through the tension sensor, so as to obtain the required tensioning distance based on the tension data.
[0020] 3. Since the winding unit of the present invention further includes a winding pulley group, the winding pulley group includes a winding fixed pulley and a winding movable pulley, and the winding cable wraps around the winding fixed pulley and the winding movable pulley at the same time. Therefore, the present invention can significantly reduce the driving power required by the winding cylinder on the premise of the same wire-drawing drag force through the winding pulley group.
[0021] 4. Since the winding pulley set of the present invention further includes a movable pulley bracket, the tension sensor is detachably arranged at one end of the movable pulley bracket. This end is used as the wire-grabbing end, and a wire anti-detachment entity is also detachably arranged at the wire-grabbing end. The wire anti-detachment entity is located near the winding movable pulley and is used to prevent the winding movable pulley from getting out of the wire. When the overhead line is traction-coupled through the wire-grabbing end, the instantaneous gravity of the overhead line will cause the winding movable pulley to get out of the wire. Therefore, the present invention can avoid the winding movable pulley from getting out of the wire through the wire anti-detachment entity, so that the winding movable pulley is always coupled with the winding pulley.
[0022] 5. Since the present invention further includes a synchronous wire arranging assembly, the synchronous wire arranging assembly includes a wire arranging guide rail, a wire arranging slider and a synchronous driving member. The wire arranging guide rail extends in the same direction as the rotating shaft of the winding cylinder. The wire arranging slider is matched with the wire arranging guide rail and can move linearly. The synchronous driving member is coupled with the wire arranging slider and is used to drive the wire arranging slider to move. The wire arranging slider is located between the winding cylinder and the winding pulley set, and the wire arranging slider is formed with a wire passing through hole. The winding wire passes through the wire passing through hole. Therefore, when the winding cylinder winds the winding wire, the winding position changes linearly along the axial direction of the winding cylinder, so that the winding distribution of the winding wire on the winding cylinder is relatively average, and there will be no situation of local concentrated accumulation of the winding wire.
[0023] 6. Since the synchronous driving member of the present invention is a shaft rod parallel to the winding cylinder, and both the synchronous driving member and the winding cylinder have mutually meshing synchronous coupling gears. The peripheral surface of the driving member forms a spiral cam groove extending along the axial direction, and the wire arranging slider has a driving protrusion matched with the spiral cam groove. When the winding cylinder rotates, it drives the synchronous driving member to rotate, so that the spiral cam groove drives the wire arranging slider to move on the wire arranging guide rail. Therefore, driven by the synchronous driving member that rotates synchronously with the winding cylinder, when the winding wire wraps around the winding cylinder for one week, the wire arranging slider correspondingly moves a distance equal to the diameter length of a winding wire, so that the winding wire is not only evenly distributed on the winding cylinder, but also the utilization rate of the winding position on the peripheral surface of the winding cylinder is the best.
[0024] 7. Since the wire arranging slider of the present invention includes a slider main body and a driving protrusion, and the driving protrusion is a mating roller that can rotate relative to the slider main body. When the spiral cam groove drives the wire arranging slider to move on the wire arranging guide rail, the mating roller rolls in contact with the inner wall of the spiral cam groove. Therefore, through the rotatable driving protrusion, the present invention makes the frictional resistance suffered by the driving protrusion extremely small during the movement in the spiral cam groove, so that the driving protrusion is not easily damaged or broken in the spiral cam groove due to obstruction during long-term use.
[0025] 8. Since the synchronous driving member of the present invention further has an end-sealing entity, the end-sealing entity is located at the end of the synchronous driving member, and the end-sealing entity is detachably arranged. The end-sealing entity is used to close or open the spiral cam groove. Therefore, through the detachable end-sealing entity of the present invention, even when the wire arranging slider or the driving protrusion is damaged, the spiral cam groove can be opened, and the wire arranging slider and the driving protrusion can be removed, thus greatly improving the maintainability of the device.
[0026] 9. Since the present invention further includes a base and a main driving assembly, the main driving assembly includes a main driving motor and a main driving gear. The driving gear is arranged on the output shaft of the main driving motor, and the winding cylinder has a driven gear that meshes with the driving gear. When the driving motor drives the driving gear to rotate, the winding cylinder rotates passively through the driven gear. Therefore, the present invention realizes the speed-reducing drive of the main driving motor to the winding cylinder through the driving gear and the driven gear.
[0027] 10. Since the present invention further includes a portable terminal that is signal-connected to the main driving motor, and the portable terminal drives the main driving motor to act by inputting an instruction, the present invention enables the operator to remotely control the wire tightening at a safe position through the overhead line wire tightening fine-tuning device, thus greatly improving the safety of the operator's operation.

Detailed implementation manners
[0038] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the following embodiments will specifically describe the overhead line tightener fine-tuning device of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.
[0039] As Figures 2 to 4 shown, the overhead line tightener fine-tuning device 100 in this embodiment includes a base 10, a main driving assembly 20, a fixing member 30, a winding unit 40, a synchronous wire arranging assembly 50, an energy supply member 60 and a portable terminal (not shown in the drawings).
[0040] The fixing member 30 and the winding unit 40 are both arranged on the base. Specifically, the base 10 is semi-closed by a housing S. The base 10 is integrally formed with a base partition 11. The base partition 11 divides the base 10 into two independent spaces. One of the spaces is used as the driving area 10a, the middle of the other space is used as the mechanism area 10b, and the opposite sides of the other space are both used as the traction areas 10c, and both traction areas 10c are open towards the outside of the base 10.
[0041] Specifically, the main driving assembly 20 is arranged on the base partition 11, the energy supply member 60 is arranged in the driving area 10a, part of the winding unit 40 and the synchronous wire arranging assembly 50 are arranged in the mechanism area 10b, and the synchronous wire arranging assembly 50 is closer to the traction area 10c. The remaining part of the winding unit 40 and the fixing member 30 are both arranged in the traction area 10c.
[0042] The main drive assembly 20 includes a main drive motor 21 and a main drive gear 22. The main drive gear 22 is disposed on the output shaft of the main drive motor 21. Specifically, the main drive motor 21 is located within the drive area 10a. The main drive motor 21 extends into the mechanism area 10b through the base partition 11, and the main drive gear 22 is located within the mechanism area 10b.
[0043] The fixing member 30 is connected to a cross arm or a pole tower (not shown in the drawings).
[0044] The winding unit 40 is fixedly connected to the fixing member 30 through the base 10. The winding unit 40 includes a winding drum 41, a winding cable 42, a rotary encoder 43, and a winding pulley group 44. In this embodiment, the fixing member 30 and the winding unit 40 have the same structure, and the two are symmetrically distributed in a mirror image on the base 10.
[0045] The winding drum 41 is parallel to the output shaft of the main drive motor 21. The winding drum 41 has a driven gear 411 that meshes with the main drive gear 22. When the drive motor 21 drives the main drive gear 22 to rotate, the winding drum 41 rotates passively through the driven gear 411.
[0046] One end of the winding cable 42 is fixed to the winding drum 41, and the other end is traction-coupled to an overhead line to be tightened (not shown in the drawings) through the winding pulley group 44. The rotary encoder 43 is rotationally coupled to the winding drum 41. When the winding drum 41 winds and stores the winding cable 42 through rotation, the overhead line to be tightened is tightened.
[0047] The winding pulley group 44 includes a winding fixed pulley 441 and a winding movable pulley 442. The winding cable 42 wraps around both the winding fixed pulley 441 and the winding movable pulley 442. Specifically, the winding fixed pulley 441 is fixedly provided in the traction area 10c, and the winding movable pulley 442 is located outside the base 10. The winding movable pulley 442 has a connecting bracket (not shown in the drawings), and a traction hook 443 is provided on the connecting bracket. The winding movable pulley 442 traction-couples the overhead line to be tightened through the traction hook 443. Thus, the winding movable pulley 442 maintains a balanced state through the relative tension between the overhead line to be tightened and the winding cable 10. All other winding units 40 except the winding pulley group 44 are located within the mechanism area 10b.
[0048] As Figure 5As shown, the winding pulley set 44 further includes a movable pulley bracket 442a. The winding movable pulley 442 is rotatably arranged on the movable pulley bracket 442a, and one end of the movable pulley bracket 442a is also detachably provided with a tension sensor 443a. Thus, the end of the winding cable 42 is traction-coupled to the overhead line to be tightened through the tension sensor 443a. Specifically, the tension sensor 443a is arranged at the end of the connecting bracket, so that the connecting bracket is connected to the traction hook 443 through the tension sensor 443a, and the tension sensor 443a is a wireless sensor. When the line tightening operation is performed, the tension sensor 443a can collect the tension of the overhead line to be tightened in real time.
[0049] Take the end of the movable pulley bracket 442a coupled with the tension sensor 443a as the wire-grabbing end. The wire-grabbing end is also detachably provided with an anti-detachment rope entity 442b. The anti-detachment rope entity 442b is located near the winding movable pulley 442, and the anti-detachment rope entity 442b is used to prevent the winding movable pulley 442 from detaching from the rope. In this embodiment, the winding movable pulley 442 is a concave pulley with a concave circumferential surface. The winding cable 42 is embedded in the circumferential groove of the winding movable pulley 442. The anti-detachment rope entity 442b is a protruding entity towards the groove of the winding movable pulley 442, and the clearance between the anti-detachment rope entity 442b and the edge of the groove of the winding movable pulley 442 is smaller than the nominal diameter of the winding cable 42. Thus, the winding cable 42 can never escape from the groove of the winding movable pulley 442 due to the obstruction of the anti-detachment rope entity 442b.
[0050] As Figure 6 and Figure 7 shown, the synchronous wire arranging assembly 50 is located near the winding cylinder 41. The synchronous wire arranging assembly 50 includes a wire arranging guide rail 51, a wire arranging slider 52 and a synchronous driving member 53.
[0051] The wire arranging guide rail 51 extends in the same direction as the rotating shaft of the winding cylinder 41. Specifically, the wire arranging guide rail 51 is fixedly arranged on the bottom surface of the driving area 10a.
[0052] The synchronous driving member 53 is a shaft rod parallel to the winding cylinder 41. The synchronous driving member 53 has a synchronous coupling gear 531 and a spiral cam groove 532. Specifically, the synchronous driving member 53 is located directly above the wire arranging guide rail 51.
[0053] The synchronous driving member 53 and the winding cylinder 41 are meshed with each other through the synchronous coupling gear 531 and the driven gear 411. When the winding cylinder 41 rotates, it drives the synchronous driving member 53 to rotate synchronously. The spiral cam groove 532 is formed on the circumferential surface of the synchronous driving member 53 and extends along the axial direction of the synchronous driving member 53.
[0054] As Figure 8As shown, the synchronous driving member 53 further has end-sealing entities 533. The end-sealing entity 553 is located at the end of the synchronous driving member 53, and the end-sealing entity 533 is detachably provided. The end-sealing entity 533 is used to close or open the spiral cam groove 532. That is, when the end-sealing entity 533 is in the assembled state, the end of the spiral cam groove 532 is blocked by the side of the end-sealing entity 533 and thus closed; when the end-sealing entity 533 is in the disassembled state, the end of the spiral cam groove 532 is open outward. In this embodiment, the number of end-sealing entities 533 is two, which are assembled at both ends of the synchronous driving member 53 through threaded connections to close the spiral cam groove 532. Thus, the synchronous driving member 53 is generally cylindrical, with thicker ends and a thinner middle. The synchronous coupling gear 531 is sleeved on the circumferential surface of one end-sealing entity 533.
[0055] The wire arranging slider 52 is located between the corresponding winding cylinder 41 and the winding pulley group 44, and the wire arranging slider 52 is matched with the wire arranging guide rail 51 and can move linearly.
[0056] As Figure 9 shown, the wire arranging slider 52 includes an integrally formed slider main body 52a and a driving protrusion 52b. Specifically, the wire arranging slider 52 extends vertically.
[0057] The slider main body 52a of the wire arranging slider 52 has a wire passing through hole 521. Specifically, the slider main body 52 is threaded through the wire arranging guide rail 51.
[0058] The driving protrusion 52b is a mating roller that can rotate relative to the slider main body 52a. When the spiral cam groove 532 drives the wire arranging slider 52 to move on the wire arranging guide rail 51, the driving protrusion 52b rolls in contact with the inner wall of the spiral cam groove 532.
[0059] The winding cable 42 on the winding pulley group 44 passes through the wire passing through hole and reaches the winding cylinder 41 and is wound; the driving protrusion cooperates with the spiral cam groove 532 and can move along the spiral cam groove 532, so that the synchronous driving member 53 is coupled with the wire arranging slider 52. That is, the synchronous driving member 53 drives the wire arranging slider 52 to move on the wire arranging guide rail 51 through the spiral cam groove 532.
[0060] Specifically, the energy supply member 60 is a power supply assembly for providing electrical energy to related components.
[0061] The portable terminal is signal-connected to the main driving motor 21. The portable terminal drives the main driving motor 21 to act by inputting an instruction. Specifically, the portable terminal has a button and a display screen. Through the button, the operator can input an input instruction, and through the display screen, the operator can observe the tight wire length data obtained in real time based on the rotary encoder 43 and the tension data of the overhead line feedback by the tension sensor 443a in real time.
[0062] The above embodiments are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by those of ordinary skill in the art without creative labor within the scope of the appended claims still fall within the protection scope of this patent.
