Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power grid erection tools, in particular to an adjustable tensioning dual-purpose machine. BACKGROUND

[0002] The tensioning dual-purpose machine can realize the traction recovery of the cable and the tension pay-off of the cable, and has the functions of the existing traction machine and tension machine. When it performs traction recovery, the main variable pump in the hydraulic system outputs hydraulic oil to drive the quantitative main hydraulic motor with a brake to operate and rotate the drum, and the cable is pulled to move by the drum to realize the traction recovery of the cable. When it performs tension pay-off, the variable swash plate of the main variable pump in the hydraulic system is zero degree, at this time, the main variable pump has no hydraulic oil output, and the quantitative main hydraulic motor is used as a hydraulic pump to push the hydraulic oil in the related hydraulic system. At this time, the overflow valve is arranged in the related hydraulic system, so that when the hydraulic oil passes through the overflow valve, the pressure difference of the two oil ports of the quantitative main hydraulic motor can be adjusted by adjusting the pressure of the overflow valve, so that the resistance torque generated by the adjusted pressure difference can offset the tension of the cable during pay-off, and the safety of pay-off is guaranteed.

[0003] However, in actual use, since the drum has a certain width, the cable will be inclined when wound on the drum, and after the cable is wound on the drum, it needs to be wound on the wire guide disc of the winch mechanism. However, since the position of the winch mechanism in the axial direction of the drum cannot be changed, when traction recovery and tension pay-off are performed, the cable will be in a state of being inclined when wound on the drum, which will cause the cable to be subjected to excessive lateral tension, and the cable is prone to slip along the axial direction of the drum on the drum and the winch mechanism. Not only there is a risk of cable wear, but also there is a great safety hazard. SUMMARY

[0004] In view of the above problems in the prior art, the present application provides an adjustable tensioning dual-purpose machine, which is provided with a guide support with an angle sensor, and a slidable winch mechanism. When the cable is inclined between the drum and the winch mechanism, the angle sensor on the guide support detects the inclination signal and adjusts the position by sliding the winch mechanism, so that the winch mechanism moves to be in a straight line with the cable at the winding and unwinding point on the drum, and the cable is straightened, thereby reducing the lateral tension of the cable on the drum, the guide support and the winch mechanism, reducing the risk of the cable slipping along the axial direction of the drum on the drum, the guide support and the winch mechanism, effectively avoiding the problem that the cable is easily worn during tensioning work, and improving the safety performance.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the following embodiments are combined with the accompanying drawings to Figure 1 to the accompanying Figure 4 The technical solutions provided by the application are described in detail, but the following content is not a limitation of the application.

[0026] Figure 1 This is a structural diagram of an embodiment of an adjustable tensioning machine according to the present invention. Figure 1 As shown, the adjustable traction / tensioning machine provided in this embodiment includes: a frame 1, a powertrain 2, a drum 3, a controller 4, and a hydraulic system 5. The powertrain 2, drum 3, controller 4, and hydraulic system 5 are all mounted on the frame 1, which provides the mounting base for these components. Furthermore, the powertrain 2 and hydraulic system 5 are electrically connected to the controller 4, meaning the controller 4 controls the operation of the fuel engine in the powertrain 2 and the opening and closing of the valves in the hydraulic system 5, thereby meeting the requirements for using either a traction recovery line or a tension release line. Furthermore, the powertrain 2 is connected to the hydraulic system 5. The fuel engine in the powertrain 2 drives the variable pump in the hydraulic system 5, which in turn drives the hydraulic motor to move. The hydraulic motor is connected to the drum 3 via the reducer 51, thus driving the drum 3 to complete the cable traction and retrieval operation. This hydraulic drive also ensures that the rotation of the drum 3 is hydraulic, resulting in high torsional force and strong load-bearing capacity, making it more suitable for the power requirements of cable traction and retrieval. In addition, during tension cable release, the variable pump in the hydraulic system 5 does not work. At this time, the hydraulic motor is used as a hydraulic pump. The cable pulls the drum 3 to rotate during release, and the drum 3 drives the hydraulic motor in the opposite direction via the reducer 51. The resistance torque generated by adjusting the pressure difference in the hydraulic system 5 is used to counteract the tension of the cable during release, ensuring cable release safety.

[0027] Figure 2 This is a schematic diagram of the installation of the winch mechanism on the vehicle frame according to a preferred embodiment of the present invention; Figure 3 for Figure 2 An enlarged view of section A. (See image below.) Figure 1 , Figure 2 as well as Figure 3The winch mechanism 6 further comprises a wire guide wheel 61, a support frame 62, a first sliding frame 63 and a sliding telescopic drive 64. The first sliding frame 63 is slidably arranged on the tail of the vehicle frame 1 along the axial direction of the winding drum 3, so that the first sliding frame 63 can be moved to different positions along the axial direction of the winding drum 3. One end of the support frame 62 is mounted on the first sliding frame 63, and the other end of the support frame 62 extends out of the vehicle frame 1. The wire guide wheel 61 is rotatably mounted on the support frame 62, so that the first sliding frame 63 can drive the wire guide wheel 61 to move to different positions along the axial direction of the winding drum 3 through the support frame 62. Meanwhile, the sliding telescopic drive 64 is mounted on the vehicle frame 1 along the axial direction of the winding drum 3, and the driving shaft of the sliding telescopic drive 64 is connected with the first sliding frame 63, so that the first sliding frame 63 can be driven to reciprocate on the vehicle frame 1 along the axial direction of the winding drum 3 through the sliding telescopic drive 64. Thus, the wire guide wheel 61, the guide bracket 7 and the winding drum 3 can be moved to the same straight line in sequence, so that the cable can be straightened along the axial direction of the winding drum 3 between the winch mechanism 6, the guide bracket 7 and the winding drum 3, and the cable can be adjusted, thereby avoiding excessive lateral tension on the cable on the winding drum 3, the guide bracket 7 and the winch mechanism 6, reducing the risk of sliding of the cable along the axial direction of the winding drum 3 on the winding drum 3, the guide bracket 7 and the winch mechanism 6, effectively avoiding the problem that the cable is easily worn during tensioning, and providing safety.

[0028] Figure 4 A perspective view of the guide bracket of a preferred embodiment of the present application. Figure 1 and Figure 4As shown, the guide bracket 7 is arranged on the frame 1 and between the winding mechanism 6 and the winding drum 3, serving as a support and guide structure for the cable between the winding mechanism 6 and the winding drum 3. At this time, the guide bracket 7 further comprises an angle sensor 71, a cross frame 72, a second sliding bracket 73, a horizontal guide wheel 74, and two vertical guide wheels 75. The lower end of the cross frame 72 is fixed to the frame 1 and between the winding drum 3 and the winding mechanism 6, achieving stable installation of the guide bracket 7 on the frame 1. Moreover, the second sliding bracket 73 is slidably arranged on the cross frame 72 along the axial direction of the winding drum 3, so that the second sliding bracket 73 can reciprocate along the axial direction of the winding drum 3. When the cable is later inclined, the second sliding bracket 73 can be adjusted to straighten the cable, reducing the risk of sliding of the cable along the axial direction of the winding drum 3 on the winding drum 3, the guide bracket 7 and the winding mechanism 6, and preventing the problem of sliding wear of the cable. At the same time, the vertical guide wheels 75 are arranged in the vertical direction and installed at both ends of the second sliding bracket 73. Meanwhile, the horizontal guide wheel 74 is arranged along the axial direction of the winding drum 3 and rotatably installed on the second sliding bracket 73, and the horizontal guide wheel 74 is arranged between the two vertical guide wheels 75. The horizontal guide wheel 74 supports the cable, meeting the support and guide requirements. Moreover, the two vertical guide wheels 75 can limit both ends of the horizontal guide wheel 74, preventing the cable from falling off the guide bracket 7 from the horizontal guide wheel 74. At the same time, the angle sensor 71 is installed between the horizontal guide wheel 74 and the second sliding bracket 73, providing conditions for the subsequent angle sensor 71 to be connected with the cooperation structure of the horizontal guide wheel 74. Moreover, the angle sensor 71 can move with the second sliding bracket 73, meeting the use requirement of real-time monitoring of the deflection angle.

[0029] More specifically, the horizontal guide wheel 74 on the guide support 7 further comprises a U-shaped bracket 741, a rotating shaft 742, a wheel shaft 743, a wheel body 744 and a bearing bracket 745. At this time, the opening of the U-shaped bracket 741 is arranged upward, and the wheel body 744 is rotatably installed on the wheel shaft 743, realizing the rotation of the wheel body 744 on the wheel shaft 743. At the same time, the wheel body 744 is arranged in the opening of the U-shaped bracket 741, and the two ends of the wheel shaft 743 are arranged at the two ends of the opening of the U-shaped bracket 741, that is, the U-shaped bracket 741 realizes the stable installation of the wheel body 744, so that the wheel body 744 can freely rotate in the opening of the U-shaped bracket 741, thereby providing conditions for subsequent holding the cable and adapting to the movement of the cable. At the same time, a rotating sleeve 7411 is arranged at the bottom of the U-shaped bracket 741 and at the middle part thereof, preferably, the rotating sleeve 7411 and the U-shaped bracket 741 are of an integrated structure, and a bearing is arranged outside the rotating sleeve 7411, which is installed on the bearing bracket 745, so that the U-shaped bracket 741 can rotate on the bearing bracket 745 under the action of the rotating sleeve 7411 and the bearing, thereby realizing the deflection of the wheel body 744 on the bearing bracket 745, and the bearing bracket 745 is fixed on the second sliding bracket 73, so that the wheel body 744 can not only deflect in the horizontal plane, but also move along the axial direction of the winding drum 3. In addition, the angle sensor 71 is arranged in the bearing bracket 745 and below the rotating sleeve 7411, and the angle sensor 71 is fixed on the second sliding bracket 73, a rotating shaft 742 coaxial with the rotating sleeve 7411 is arranged in the rotating sleeve 7411 and fixed on the bottom of the U-shaped bracket 741, so that the rotating shaft 742 can deflect with the U-shaped bracket 741 in the horizontal plane, and the rotating shaft 742 is also connected to the angle sensor 71, so that when the cable is inclined, the wheel body 744 is subjected to the tension of the cable, so that the axial direction of the wheel body 744 is perpendicular to the length direction of the cable, thereby causing the U-shaped bracket 741 to deflect on the second sliding bracket 73, and the deflection signal is detected by the angle sensor 71. At this time, the sliding telescopic drive 64 in the winch mechanism 6 is synchronously controlled to act, and the guide wire disc 61 is pushed to move until the cable is perpendicular to the axial direction of the winding drum 3. At this time, the U-shaped bracket 741 is also deflected to the reset position in the opposite direction, and the angle sensor 71 no longer detects the angle signal, thereby stopping the action of the sliding telescopic drive 64. Conversely, the action of each structure is controlled in the opposite direction, which also meets the use requirement. It is worth noting that the angle sensor 71 is electrically connected to the controller 4, the sliding telescopic drive 64 is electrically connected to the controller 4, and the angle direction of the angle sensor 71 and the telescopic movement relationship of the sliding telescopic drive 64 are pre-set, that is, when the angle sensor 71 detects that the deflection direction of the U-shaped bracket 741 is counterclockwise from one side of the winding drum 3 to the guide wire disc 61, the driving shaft of the sliding telescopic drive 64 is extended, and when the angle sensor 71 detects that the deflection direction of the U-shaped bracket 741 is clockwise from the guide wire disc 61 to the winding drum 3, the driving shaft of the sliding telescopic drive 64 is retracted. Figure 1 Figure 1 ​When the cable is deflected from the wire guide disc 61 side to the winding drum 3 side in the clockwise direction, the drive shaft of the sliding telescopic drive 64 is retracted, so that the inclined cable can be automatically adjusted to be straightened, the cable is adjusted, the lateral force of the cable is reduced, the risk of sliding of the cable along the winding drum 3 in the axial direction of the winding drum 3, the guide support 7 and the winding mechanism 6 is reduced, and the wear of the cable is reduced. The structure design is more reasonable.

[0030] It is worth pointing out that when the cable needs to be inclined and wound on the wire guide disc 61 or the winding drum 3, the angle sensor 71 can be closed, and the sliding telescopic drive 64 is actively controlled to drive the guide wheel disc to reciprocate along the axial direction of the winding drum 3, so as to realize the misalignment of the guide wheel disc and the winding drum 3, thereby realizing the inclined winding of the cable and meeting different use requirements, and the adaptability is higher.

[0031] More specifically, the wheel body 744 of the horizontal guide wheel 74 is provided with a guide groove 7441, and the guide groove 7441 is an annular structure and is arranged on the circumference of the wheel body 744. At this time, the cable is clamped into the guide groove 7441, that is, the position of the cable on the wheel body 744 is limited by the guide groove 7441, preventing the cable from detaching from the wheel body 744, and the safety and stability are higher. At the same time, when the wheel body 744 rotates, the wheel body 744 can always be perpendicular to the length direction of the cable through the action of the guide groove 7441, so as to ensure that the U-shaped frame 741 can follow the deflection of the cable, so that the angle sensor 71 can more accurately detect the deflection signal, and the structure design is more reasonable.

[0032] More specifically, the wheel body 744 of the horizontal guide wheel 74 is provided with a plurality of guide grooves 7441, and the groove widths of the guide grooves 7441 on the plurality of wheel bodies 744 are different, so that the guide grooves 7441 with different groove widths can adapt to the support and guide requirements of cables with different diameters. And the two ends of the opening of the U-shaped frame 741 are provided with upward bifurcations, one end of the wheel shaft 743 is hinged in one bifurcation, and the other end of the wheel shaft 743 is clamped in the other bifurcation and locked by a threaded fastener. The end of the wheel shaft 743 can be moved out of the bifurcation and rotated in the other bifurcation, so as to facilitate the replacement of the wheel body 744 on the wheel shaft 743, that is, the operator can replace the wheel body 744 with the appropriate groove width of the guide groove 7441 and install it on the wheel shaft 743 under different use conditions, so as to meet different use requirements, and the structure adaptability is higher.

[0033] More specifically, the second sliding frame 73 on the guide support 7 further comprises a second sliding block 731 and a second guide rail 732, at this time, the bottom of the second guide rail 732 is fixed on the cross frame 72 and arranged along the axial direction of the winding drum 3, and a limiting block is arranged at both ends of the second guide rail 732, and the second sliding block 731 is slidingly arranged on the second guide rail 732, so that the second sliding block 731 can move along the axial direction of the winding drum 3 on the second guide rail 732, and the second sliding block 731 can be prevented from falling off the second guide rail 732, and the safety is higher. In addition, the angle sensor 71 and the bearing frame 745 are both mounted on the sliding block, so that the installation of the angle sensor 71 and the bearing frame 745 on the sliding block is realized, thereby adapting to the change of the inclined direction of the cable.

[0034] More specifically, one end of the support frame 62 is hinged to the first sliding frame 63, so that the support frame 62 can swing on the first sliding frame 63, and the wire wheel disc 61 mounted on the support frame 62 can not only swing by itself, but also move with the first sliding frame 63. At this time, the swing surface of the support frame 62 is a vertical surface, so that the height of the wire wheel disc 61 is adjusted, and the tensioning requirement in different situations is met. At this time, the deflection telescopic drive 65 is arranged between the first sliding frame 63 and the support frame 62, the deflection telescopic drive 65 is driven to swing by the telescopic movement of the deflection telescopic drive 65, and the deflection telescopic drive 65 is electrically connected to the controller 4, so as to facilitate the operation of the operator.

[0035] More specifically, the first sliding frame 63 of the hoisting mechanism 6 further comprises a first guide rail 631 and a sliding plate 632, the first guide rail 631 is arranged on the vehicle frame 1 along the axial direction of the winding drum 3, and the sliding plate 632 is slidingly arranged on the first guide rail 631, so that the sliding plate 632 can move along the axial direction of the winding drum 3 on the first guide rail 631. And the sliding plate 632 is connected with the driving shaft of the sliding telescopic drive 64, one end of the support frame 62 is hinged to the sliding plate 632, the installation of the support frame 62 on the sliding plate 632 is realized, and the side of the sliding plate 632 close to the wire wheel disc 61 extends to the outside of the vehicle frame 1 and extends towards the bottom of the vehicle frame 1, and the two ends of the deflection telescopic drive 65 are respectively hinged to the part of the sliding plate 632 extending to the bottom of the vehicle frame 1 and the support frame 62, the part of the sliding plate 632 extending to the bottom of the vehicle frame 1 provides a mounting basis for the deflection telescopic drive 65, so that the deflection telescopic drive 65 can move with the sliding plate 632 and the support frame 62, so as to ensure that the deflection telescopic drive 65 can always act on the support frame 62, and the structure design is more reasonable.

[0036] More specifically, the frame 1 and the winding mechanism 6 are further provided with a reinforcing device 8, which improves the installation stability and reliability of the winding mechanism 6 on the frame 1. At this time, the reinforcing device 8 comprises a positioning frame 81, a rotating pressure rod 82 and a pressure wheel 83. The lower end of the positioning frame 81 is installed at the tail end of the frame 1 and located on the side of the sliding plate 632 away from the wire wheel disc 61, so that the reinforcing device 8 can avoid the support frame 62 and prevent the reinforcing device 8 from blocking the movement of the sliding plate 632. At this time, the upper end of the positioning frame 81 extends above the sliding plate 632, and a rotating pressure rod 82 is rotatably installed on the upper end of the positioning frame 81, and the axis of the rotating pressure rod 82 is perpendicular to the axis of the winding drum 3. At the same time, one end of the rotating pressure rod 82 extends towards the sliding plate 632, and the pressure wheel 83 is rotatably installed on the rotating pressure rod 82 and presses against the sliding plate 632. In this way, the frame 1 presses the sliding plate 632 through the positioning frame 81, the rotating pressure rod 82 and the pressure wheel 83, preventing the sliding plate 632 from disengaging from the first guide rail 631, improving the stability and carrying capacity of the first sliding frame 63, and providing higher safety protection. At the same time, it can also meet the use requirements of the sliding plate 632 moving on the first guide rail 631.
