Description

Technical Field

[0001] The present application relates to the technical field of power distribution networks, and in particular to a wire bending device and method. Background Art

[0002] At present, for the installation of electric poles in distribution networks, it is usually necessary to use guy wires (such as steel strands, etc.) to anchor them, so as to balance the forces acting on the electric poles from all sides and resist wind pressure, thereby preventing the electric poles from tilting and further preventing the electric poles from falling. When using guy wires to anchor electric poles, it is generally necessary to bend the guy wires so that they can fit with the wedge-shaped wire clamps. In the related art, the bending of the wire mostly relies on manual operation, and this manual bending has many shortcomings: first, due to individual differences in the technical level of manual operation, the quality of the wire during the bending process is difficult to guarantee, which is specifically manifested in that the wire and the tongue plate of the wedge-shaped wire clamp cannot fully fit together; secondly, the manual bending process is relatively complicated, and it consumes a lot of physical strength and energy of the workers. As the working hours increase, the workers are very likely to become physically exhausted or distracted, which will not only greatly reduce the bending efficiency of the wire, but also directly lead to a decline in the quality of the wire, and the qualified rate of the wire will also decrease accordingly; thirdly, the wire has a certain elasticity after bending, and the workers are easily injured by the wire, which results in poor safety.

DETAILED DESCRIPTION

[0026] In the related art, the bending of the wire mostly relies on manual operation, and this manual bending has many shortcomings: first, due to individual differences in the technical level of manual operation, the quality of the wire during the bending process is difficult to guarantee, resulting in the wire and the tongue plate of the wedge-shaped wire clamp not being able to fully fit together; second, the manual bending process is relatively complicated, and it consumes a lot of physical strength and energy of the staff. With the increase in working hours, the staff is very likely to become physically exhausted or distracted, which will not only greatly reduce the bending efficiency of the wire, but also directly lead to a decline in the quality of the wire, and the qualified rate of the wire will also decrease accordingly; third, the wire has a certain elastic force after bending, and the staff can easily be injured by the wire, which is less safe. In view of this, the present application proposes a wire bending device and method in the following embodiments to solve the above-mentioned drawbacks in the related art.

[0027] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] See also Figures 1 to 6 , Figure 1 It is a structural diagram of the wire bending device. Figure 2 This is an exploded schematic diagram of the wire bending device. Figure 3 yes Figure 2 A partial enlarged view of point A in the middle. Figure 4 yes Figure 2 A partial enlarged view of point B in the middle. Figure 5 It is a schematic diagram of the structure of the wire bending device in the initial state. Figure 6It is a structural schematic diagram of a wire bending device in a terminal state. This embodiment provides a wire bending device, which includes a power device 2, a rotating plate 3, a fixed wheel 4, a driving wheel 5, a driven wheel 6, a fixed shaft 7, a driving shaft 8, a driven shaft 9 and a hollow box body 1. The power device 2 is arranged in the box body 1, one end of the driving shaft 8 is arranged on the box body 1 and extends into the box body 1 to connect with the power device 2, the driving shaft 8 is rotatably matched with the box body 1, one end of the rotating plate 3 is sleeved on the driving shaft 8, the driving wheel 5 is sleeved on the driving shaft 8 and arranged on the rotating plate 3, one end of the driven shaft 9 is arranged on the other end of the rotating plate 3, the driven wheel 6 is sleeved on the driven shaft 9 and rotatably matched with the driven shaft 9, the driven wheel 6 is opposite to the driving wheel 5 and spaced from each other, one end of the fixed shaft 7 is arranged on the box body 1, and the fixed wheel 4 is sleeved on the fixed shaft 7 and rotatably matched with the fixed shaft 7. Preferably, the fixed shaft 7 adopts a locking pin and the driven shaft 9 adopts a locking shaft.

[0029] In this embodiment, the wire bending device has an initial state and an end state. In the initial state, the fixed wheel 4 and the driven wheel 6 are opposite to each other in the width direction of the box body 1 and are spaced apart from each other (such as Figure 5 As shown, in the final state, the fixed wheel 4 and the driven wheel 6 are opposite to each other in the length direction of the box body 1 and are spaced apart from each other (as shown in FIG. Figure 6 As shown in the figure, the driving wheel 5, the driven wheel 6 and the fixed wheel 4 are all formed with an inwardly concave annular groove 10. The annular groove 10 of the driving wheel 5 is used to accommodate one side of the cable to be bent, and the annular grooves 10 of the fixed wheel 4 and the driven wheel 6 are used to accommodate the other side of the cable opposite. Further, the power device 2 is used to: when the cable bending device is in the initial state, drive the driving shaft 8 together with the rotating plate 3 and the driving wheel 5 to rotate forward (i.e. along the Figure 5 The driven wheel 6 rotates in the direction of the arrow in the middle), so that the driven wheel 6 rotates away from the fixed wheel 4 until the wire bending device enters the terminal state, thereby bending the wire; when the wire bending device is in the terminal state, the driving shaft 8 is driven to reverse together with the rotating plate 3 and the driving wheel 5 (i.e., along the Figure 5 The driven wheel 6 rotates toward the direction adjacent to the fixed wheel 4 until the cable bending device returns to the initial state, so that the staff can remove the bent cable.

[0030] That is to say, the process of bending the cable by the cable bending device is: placing the cable bending device in an initial state; inserting one end of the cable between the driving wheel 5 and the driven wheel 6, so that the annular groove 10 of the driving wheel 5 accommodates one side of the cable (that is, one side of the cable abuts against the groove wall of the annular groove 10 of the driving wheel 5), and the annular grooves 10 of the fixed wheel 4 and the driven wheel 6 both accommodate the other side of the cable opposite to the fixed wheel 4 (that is, the other side of the cable abuts against the groove walls of the annular grooves 10 of the driven wheel 6 and the fixed wheel 4 at the same time), thereby supporting the cable through the fixed wheel 4 and limiting the cable between the driving wheel 5 and the driven wheel 6; use the power device 2 to drive the active shaft 8 together with the rotating plate 3 and the active wheel 5 to rotate forward, and then drive the driven wheel 6 to rotate in the direction away from the fixed wheel 4 until the wire bending device enters the terminal state, thereby realizing the bending of the wire; after the wire is bent, use the power device 2 to drive the active shaft 8 together with the rotating plate 3 and the active wheel 5 to reverse, and then drive the driven wheel 6 to rotate in the direction adjacent to the fixed wheel 4 until the wire bending device returns to the initial state, so that the bent wire can be pulled out from between the active wheel 5 and the driven wheel 6; after that, the above process can be repeated to bend the next wire. In addition, it should be noted that during the bending process of the wire, the fixed wheel 4 will rotate around the fixed shaft 7 under the action of friction, and the driven wheel 6 will also rotate around the driven shaft 9 under the action of friction, which can effectively avoid scratching the wire. It should also be noted that in order to ensure the smooth rotation of the turn plate 3 around the driving shaft 8 during the wire bending process, a guide structure can be added to the box body 1, such as opening an arc groove around the driving shaft 8 on the box body 1, and providing a slider on the bottom side of the turn plate 3, the slider is located in the arc groove and slides with the arc groove, so that when the power device 2 drives the driving shaft 8 together with the turn plate 3 and the driving wheel 5 to rotate forward / reverse, the slider will slide in the arc groove, and this guide structure can effectively improve the smooth rotation of the turn plate 3 around the driving shaft 8, thereby ensuring the stability of the wire bending, and further ensuring the bending quality of the wire.

[0031] As can be seen from the above, compared with the manual bending in the traditional scheme, the present embodiment realizes the automation of the bending of the wire, that is, the bending of the wire does not require human participation, thereby simplifying the bending process, reducing the labor intensity of the staff, and improving the bending efficiency and quality of the wire; moreover, the wire is still confined in the annular groove 10 of the fixed wheel 4, the driven wheel 6 and the driving wheel 5 after bending, and at the same time, the elastic force of the wire will be slowly released due to the rotation of the driven wheel 6 toward the direction adjacent to the fixed wheel 4, which avoids the staff from being injured by the wire, thereby improving the safety of the wire bending and ensuring the life safety of the staff; in addition, the distance between the driving wheel 5 and the driven wheel 6 can be changed by replacing the driving wheel 5, so as to adapt to wires of different specifications (i.e., different sizes), thereby improving the applicability of the wire bending device.

[0032] In some embodiments, see Figures 1 to 6The power device 2 includes a motor 21, a worm gear reduction box 22 and a controller (not shown) communicatively connected to the motor 21. The motor 21 is drivingly connected to the worm gear reduction box 22 (i.e., the output shaft of the motor 21 is mechanically connected to the input end of the worm gear reduction box 22). The worm gear reduction box 22 is drivingly connected to the driving shaft 8 (i.e., the output end of the worm gear reduction box 22 is mechanically connected to one end of the driving shaft 8 extending into the housing 1). Specifically, the bending of the wire is controlled by the controller, that is, the controller is used to: when the wire bending device is in the initial state, control the motor 21 to drive the worm gear reduction box 22 to rotate forward, so that the driving shaft 8 together with the rotating plate 3 and the driving wheel 5 rotate forward, and the driven wheel 6 rotates in the direction away from the fixed wheel 4 until the wire bending device enters the terminal state, so as to bend the wire; when the wire bending device is in the terminal state, control the motor 21 to drive the worm gear reduction box 22 to reverse, so that the driving shaft 8 together with the rotating plate 3 and the driving wheel 5 reverse, and the driven wheel 6 rotates in the direction adjacent to the fixed wheel 4 until the wire bending device returns to the initial state, so as to remove the bent wire.

[0033] It is understandable that the worm gear reducer 22 has a self-locking characteristic, that is, after the motor 21 drives the worm gear reducer 22 to rotate forward so that the wire bending device enters the terminal state, although the motor 21 stops, the worm gear reducer 22 will not reverse under the elastic force of the bent wire, and the worm gear reducer 22 will only reverse under the drive of the motor 21, thereby avoiding the staff from being injured by the wire. In addition, it should be noted that the worm gear reducer 22 usually includes a worm, a worm wheel, and a bearing, etc. Since it is a relatively mature technology in this field, this application does not make too much elaboration on the structure and principle of the worm gear reducer 22. It should also be noted that the controller can use any device commonly used in this field with control and data processing and analysis functions, such as a microcontroller such as a small computer, a single-chip microcomputer, and an industrial control computer (IPC), a programmable logic controller (PLC) and a distributed control system (DCS), etc., which can be selected according to actual needs, and this application does not make a sole limitation on this.

[0034] As one embodiment, in addition to the structure given above, the wire bending device also includes an initial limit switch 11 and a final limit switch 12 which are respectively connected to the controller in communication. The initial limit switch 11 and the final limit switch 12 are both arranged on the box body 1. The initial limit switch 11 and the driven wheel 6 are opposite to each other and spaced apart in the width direction of the box body 1, and the final limit switch 12 and the driven wheel 6 are opposite to each other and spaced apart in the length direction of the box body 1. Specifically, the initial limit switch 11 is used to abut against the rotating plate 3 when the wire bending device is in the initial state, and send a stop signal to the controller; the final limit switch 12 is used to abut against the rotating plate 3 when the wire bending device is in the final state, and send a stop signal to the controller; the controller is also used to respond to the stop signal to control the motor 21 to stop. That is to say, in actual application, when the wire bending device changes from the initial state to the terminal state, once the rotating plate 3 touches the terminal limit switch 12, it means that the wire bending device has entered the terminal state and the bending of the wire has been completed. At this time, the terminal limit switch 12 will feedback a stop signal to the controller, so that the controller controls the motor 21 to stop; after the wire is bent, the wire bending device will change from the terminal state to the initial state. Once the rotating plate 3 touches the initial limit switch 11, it means that the wire bending device has entered the initial state. At this time, the initial limit switch 11 will feedback a stop signal to the controller, so that the controller controls the motor 21 to stop, and then the staff can pull the bent wire out from between the driving wheel 5 and the driven wheel 6.

[0035] Preferably, in order to ensure that the fixed shaft 7, the fixed wheel 4, the initial limit switch 11 and the terminal limit switch 12 are more stable and more reasonably distributed on the box body 1, the wire bending device, in addition to the structure given above, also includes a fixed plate 13 arranged on the box body 1, one end of the fixed shaft 7 is arranged on the fixed plate 13, the fixed wheel 4 is sleeved on the fixed shaft 7 and rotates with the fixed shaft 7, the initial limit switch 11 and the terminal limit switch 12 are both arranged on the side wall of the fixed plate 13, and at the same time meet the conditions of "the initial limit switch 11 and the driven wheel 6 are opposite and spaced from each other in the width direction of the box body 1, and the initial limit switch 11 can abut against the rotating plate 3 in the initial state; the terminal limit switch 12 and the driven wheel 6 are opposite and spaced from each other in the length direction of the box body 1, and the terminal limit switch 12 can abut against the rotating plate 3 in the terminal state".

[0036] In some embodiments, see Figures 1 to 6In addition to the structure given above, the wire bending device also includes a battery 14 and a first switch 15. The battery 14 is arranged in the box 1, and the first switch 15 is arranged on the box 1. One end of the first switch 15 is electrically connected to the battery 14, and the other end is electrically connected to the controller. The first switch 15 has an open state and a closed state. Specifically, the first switch 15 is used to enter the open state under the operation of the user to connect the battery 14 and the controller, or enter the closed state under the operation of the user to cut off the electrical connection between the battery 14 and the controller. In other words, the first switch 15 is used to control the power-on of the wire bending device. When the first switch 15 is in the open state, the battery 14 is electrically connected to the controller, and the battery 14 can supply power to the controller and the motor 21, and the wire bending device works normally; when the first switch 15 is in the closed state, the electrical connection between the battery 14 and the controller is cut off, and the battery 14 cannot supply power to the controller and the motor 21, and the wire bending device cannot work.

[0037] As one embodiment, the wire bending device includes not only the structure given above, but also a battery management module (not shown). The battery management module is arranged in the box 1, and the battery management module is electrically connected between the first switch 15 and the controller. The battery management module is mainly used to manage the battery 14, such as voltage conversion, voltage stabilization, filtering, overvoltage protection, undervoltage protection, overcurrent protection, power regulation, power distribution and information monitoring. Specifically, when the first switch 15 is in the open state, the battery 14 will output power supply energy to the outside, and the battery management module can process the power supply energy (such as voltage conversion, voltage stabilization, filtering, etc.), and transmit the processed power supply energy to the controller and the motor 21. Preferably, the battery 14 in the present application adopts a power lithium battery.

[0038] Furthermore, the wire bending device also includes a display 16 disposed on the box 1, and the display 16 is communicatively connected to the controller; specifically, the battery management module can detect the status information of the battery 14 (such as voltage, temperature, power, etc.) in real time, and transmit the status information of the battery 14 to the controller, and the controller can transmit the status information of the battery 14 to the display 16, and control the display 16 to display the status information of the battery 14, so that the staff can understand the status of the battery 14 at any time. In addition, the wire bending device also includes a charging interface 17 disposed on the box 1, and the charging interface 17 is electrically connected to the battery management module; specifically, the charging interface 17 can be electrically connected to an external power supply, and the charging power provided by the external power supply is transmitted to the battery management module, and the battery management module can use the charging power to charge the battery 14, thereby ensuring that the wire bending device has sufficient power at any time to bend the wire.

[0039] In some embodiments, see Figures 1 to 6In addition to the structure given above, the wire bending device also includes a second switch 18 disposed on the housing 1. The second switch 18 is communicatively connected to the controller, and the second switch 18 has a forward gear, a stop gear, and a reverse gear. Specifically, the second switch 18 is used to enter the forward gear under the operation of the user and send a forward signal to the controller, or enter the reverse gear under the operation of the user and send a reverse signal to the controller, or enter the stop gear under the operation of the user and send a stop signal to the controller; based on this, the controller is used to respond to the forward signal to control the motor 21 to drive the worm gear reduction box 22 to rotate forward, or respond to the reverse signal to control the motor 21 to drive the worm gear reduction box 22 to rotate reversely, or respond to the stop signal to control the motor 21 to stop. That is to say, the second switch 18 is used to control the operation of the motor 21. When the second switch 18 is in the forward gear, the controller controls the motor 21 to drive the worm gear reducer 22 to rotate forward, and the wire bending device changes from the initial state to the terminal state to bend the wire; when the second switch 18 is in the reverse gear, the controller controls the motor 21 to drive the worm gear reducer 22 to reverse, and the wire bending device changes from the terminal state to the initial state, so that the staff can pull the bent wire out from between the driving wheel 5 and the driven wheel 6; when the second switch 18 is in the stop gear, the controller controls the motor 21 to stop, and the rotating plate 3, the driving wheel 5, the driven wheel 6, etc. all stop moving. Of course, in other embodiments, the second switch 18 can also be integrated with the display 16, or even the first switch 15, the second switch 18 and the display 16 can be integrated, and the display 16 can be set as a touch screen. In this way, the status information of the battery 14 can be displayed to the staff, and the staff can also realize the functions of the first switch 15 and the second switch 18 by touching the display 16.

[0040] In some embodiments, see Figures 1 to 6 In addition to the structure given above, the wire bending device also includes a handle 19, which is provided on the box body 1. The handle 19 is used for the staff to hold it so that the staff can carry the box body 1 to move. In other words, when the wire bending device needs to be moved from the current position to another position, the staff can lift the box body 1 by the handle 19 and move the box body 1, thereby greatly improving the portability of the wire bending device.

[0041] See also Figure 7 , Figure 7The figure shows a flow chart of the wire bending method. The present embodiment provides a wire bending method, which is applied to the wire bending device described above, that is, the wire bending method is implemented based on the wire bending device described above. Specifically, the wire bending method includes steps 701 to 703 (abbreviated as S701 to S703), namely: S701, when the wire bending device is in the initial state, insert the wire between the driving wheel and the driven wheel, so that the annular groove of the driving wheel accommodates one side of the wire, and the annular grooves of the fixed wheel and the driven wheel both accommodate the other side opposite to the wire; S702, using a power device to drive the driving shaft together with the rotating plate and the driving wheel to rotate forward, so that the driven wheel rotates in a direction away from the fixed wheel until the wire bending device enters the terminal state, so as to bend the wire; S703, using a power device to drive the driving shaft together with the rotating plate and the driving wheel to reverse, so that the driven wheel rotates in a direction adjacent to the fixed wheel until the wire bending device returns to the initial state, so as to remove the bent wire. In addition, it should be noted that for any incomplete description of the wire bending method, please refer to the previous description of the wire bending device, and this embodiment will not elaborate on this in detail.

[0042] The above embodiments are only preferred implementations of the present application, and are not the only limitations on the wire bending device and related methods; in this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, the wire bending device is constituted by the power device 2, the rotating plate 3, the fixed wheel 4, the driving wheel 5, the driven wheel 6, the fixed shaft 7, the driving shaft 8, the driven shaft 9 and the hollow box 1. The power device 2 is arranged in the box 1, one end of the driving shaft 8 is arranged on the box 1 and extends into the box 1 to be connected to the power device 2, one end of the rotating plate 3 is sleeved on the driving shaft 8, the driving wheel 5 is sleeved on the driving shaft 8 and is arranged on the rotating plate 3, one end of the driven shaft 9 is arranged on the other end of the rotating plate 3, and the driven wheel 6 is sleeved on the driven shaft 8. The driven wheel 6 is opposite to the driving wheel 5 and spaced from each other. One end of the fixed shaft 7 is arranged on the box body 1. The fixed wheel 4 is sleeved on the fixed shaft 7 and rotates with the fixed shaft 7. The wire bending device has an initial state and a terminal state. In the initial state, the fixed wheel 4 and the driven wheel 6 are opposite to each other and spaced from each other in the width direction of the box body 1. In the terminal state, the fixed wheel 4 and the driven wheel 6 are opposite to each other in the length direction of the box body 1 and spaced from each other. An inwardly recessed annular groove 10 is formed on the wheel surfaces of the fixed wheel 4, the driven wheel 6 and the driving wheel 5. In actual application, the process of bending the wire by the wire bending device is: placing the wire bending device in the initial state; inserting one end of the wire between the driving wheel 5 and the driven wheel 6, so that the annular groove 10 of the driving wheel 5 accommodates one side of the wire, and the annular grooves 10 of the fixed wheel 4 and the driven wheel 6 both accommodate the other side of the wire opposite to the wire; using the power device 2 to drive the driving shaft 8 together with the rotating plate 3 and the driving wheel 5 to rotate forward, so that the driven wheel 6 rotates in the direction away from the fixed wheel 4 until the wire bending device enters the terminal state, thereby bending the wire; using the power device 2 to drive the driving shaft 8 together with the rotating plate 3 and the driving wheel 5 to reverse, so that the driven wheel 6 rotates in the direction adjacent to the fixed wheel 4 until the wire bending device returns to the initial state, so as to remove the bent wire. It can be seen that compared with the manual bending in the traditional scheme, the present application realizes the automation of the bending of the wire, that is, the bending of the wire does not require human participation, thereby simplifying the bending process, reducing the labor intensity of the staff, and thus improving the bending efficiency and quality of the wire; in addition, the wire is still confined in the annular groove 10 of the fixed wheel 4, the driven wheel 6 and the driving wheel 5 after bending, and the elastic force of the wire will be slowly released due to the rotation of the driven wheel 6 toward the direction adjacent to the fixed wheel 4, which avoids the staff from being injured by the wire, thereby improving the safety of the wire bending.
