Description

Technical Field

[0001] The utility model relates to the field of overhead wire stripping technology, in particular to an intelligent insulated overhead wire stripper. Background Art

[0002] The lead disconnection project is a very important task in power operations. Carrying out projects such as lead disconnection usually requires stripping the insulated overhead wires under power.

[0003] Automatic wire strippers are widely used due to their convenience and high efficiency. Their main working principle is to install the stripper on the wire and allow the knife head to cut into the insulation layer. The stripper rotates around the wire and moves along the length of the wire. During operation, the knife head cuts and strips the insulation layer of the wire.

[0004] When the stripper is performing the stripping operation, due to factors such as uneven insulation layer of the overhead insulated conductor and reduced strength of the overhead insulated conductor, it is difficult to accurately control the cutting depth, resulting in core damage or incomplete insulation stripping, and the overhead insulated conductor may be torsionally damaged as the stripper rotates.

[0044] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0045] 1. The present application sets a detection module and a safety protection device. The detection module detects whether the insulation layer behind the blade head following the path of the bracket is stripped off, and whether the blade head is in contact with the wire core, and feeds back to the control module according to the detection situation. If the insulation layer is stripped off, it means that the insulation layer can be stripped off under the feed amount, and the stripping operation can be successfully completed. Otherwise, if the insulation layer is not stripped off, it means that the feed amount is insufficient and the feed needs to be continued. When the blade head contacts the wire core, the wire core may be damaged. When the blade head contacts the wire core, the blade head is controlled to retract in time. When the stripper is moving for stripping, the detection module can judge in real time whether the position of the blade head is in a reasonable position. If the feed amount of the blade head is too small or too When the wire is too large, the blade feed amount is adjusted in time to avoid excessive blade feed amount that may damage the core or too small blade feed amount that may cause the insulation layer to not be stripped through; and by setting a safety protection device, the rotation speed of the bracket relative to the wire is detected when the bracket rotates around the wire. During normal operation, when the bracket and the wire rotate relative to each other, the rotation speed is kept within a certain range. When the wire rotates with the stripper, the relative rotation speed between the wire and the stripper is reduced. When it is reduced to below the set value, it indicates that the wire rotates with the stripper with a large amplitude and the wire is twisted greatly. At this time, in order to avoid damaging the wire, the rotary drive mechanism is controlled to stop running, and the stripper stops working to protect the wire and avoid safety accidents.

[0046] 2. This application controls the cutting and retracting of the cutter head through the first screw drive structure, and sets a cutting encoder to connect the cutting motor and the control module. The cutting encoder can obtain the operating parameters of the cutting motor and transmit the data to the control module. The control module can obtain the cutting amount data of the cutter head according to the data of the cutting encoder and the pitch of the cutting screw and other parameters. The control module can control the subsequent cutting amount data after the cutting or retracting according to the cutting amount data each time the cutting head contacts the wire core or the insulation layer is not stripped, so as to keep the cutting amount within a reasonable range that does not damage the core and can strip the insulation layer;

[0047] 3. The present application sets a detection roller and a first detection member. When the detection roller abuts against the wire and rotates around the wire with the bracket, the friction between the wire and the detection roller can drive the detection roller to rotate relative to the bracket. The rotation rate is proportional to the rotation rate of the bracket relative to the wire, thereby reflecting the rotation rate of the bracket relative to the wire. The bracket can rotate around the connecting axis, so that the distance of the bracket relative to the rotation axis of the bracket around the wire is adjustable, thereby adapting to the detection of wires of different wire diameters. The detection roller and the wire are kept in an abutting state by setting an elastic member, thereby improving the accuracy of the detection result.

[0048] 4. In the clamping mechanism of the present application, by setting a first trigger block and a first sensor, the first sensor can be triggered by the first trigger block after the two clamps clamp the wire in place, and the first sensor transmits a signal to the control module to control the clamping drive mechanism to stop running, which can automatically complete the function of clamping the stripper on the wire in place, so that the stripper can run safely and stably;

[0049] 5. In the clamping mechanism of the present application, a clamping encoder is set to be connected with the clamping motor and the control module. After the two clamps clamp the conductor in place, the clamping encoder can obtain the real-time operation data of the clamping motor and transmit the data to the control module. The control module can obtain the wire diameter of the clamped wire according to the data of the clamping encoder and parameters such as the pitch of the bidirectional lead screw. According to the wire diameter, real-time cutter head feed amount data and the feed amount when the insulation layer is stripped, the cutter head feed idle stroke and the thickness of the insulation layer can be obtained, and the stripper travel speed and cutter head feed speed and other parameters can be controlled according to the parameters of the wire and the insulation layer, so as to realize stepless speed operation and dynamic knife control for wires with different wire diameters and different insulation layer thicknesses, thereby improving operation efficiency under the premise of ensuring safety.

[0063] Reference Figure 1-6 As shown, an embodiment of the present application provides an intelligent insulated overhead wire stripper, which includes a bracket 1, a control module 2, a rotary drive mechanism 3, a clamping mechanism 4, a feed mechanism 5 and a safety protection mechanism 6.

[0064] Reference Figure 1-2 As shown, the rotary drive mechanism 3 includes a gear ring 31 surrounding the outside of the bracket 1, and two driving gears 32 located between the bracket 1 and the gear ring 31 are rotatably connected to the bracket 1. The axis of the driving gear 32 is parallel to the axis of the gear ring 31. The two driving gears 32 are arranged at intervals along the circumference of the gear ring 31 and are both meshed with the gear ring 31. A driving gear 33 is rotatably connected to the bracket 1. The driving gear 33 is located between the two driving paper wheels and is meshed with the two driving gears 32. At the same time, a rotary motor 34 is provided on the bracket 1 for driving the driving gear 33 to rotate; a notch is provided on the gear ring 31 for the wire to pass through so as to connect the bracket 1 to the wire. The length of the notch along the circumference of the gear ring 31 is less than the spacing between the two gears, so that when the gear ring 31 and the bracket 1 rotate relative to each other, there is always a driving gear 32 meshing with the gear ring 31. When the rotary motor 34 is started, the driving gear 33 is driven to rotate, and the driving gear 33 drives the two driving gears 32 to rotate synchronously in the same direction. The driving gear 32 and the ring gear 31 cooperate to drive the ring gear 31 and the bracket 1 to rotate relative to each other. When the ring gear 31 is restricted from rotating, the bracket 1 rotates relative to the ring gear 31, and the rotating axis of the ring gear 31 is the axis of the ring gear 31.

[0065] During the design, limit plates are set on both sides of the axial direction of the ring gear 31, and the limit plates are fixed to the bracket 1. The limit plates limit the relative movement of the ring gear 31 and the bracket 1 in the axial direction. At the same time, a shell arranged outside the ring gear 31 is fixed to the ring gear 31, and the shell extends axially along the ring gear 31 to fit with the two limit plates, so that the relative movement of the ring gear 31 and the bracket 1 in the radial direction is limited by the cooperation of the shell and the limit plates, thereby realizing the rotatable connection between the ring gear 31 and the bracket 1; a bayonet for connecting with a joystick is set on the shell, and during operation, the wire is passed through the notch of the ring gear 31 and embedded in the bracket 1, and the ground personnel connect the joystick and the bayonet to limit the rotation of the shell and the ring gear 31, so that when the rotary motor 34 is started, the bracket 1 can be driven to rotate relative to the ring gear 31, thereby realizing the function of the bracket 1 rotating around the wire.

[0066] Reference Figure 2 As shown, the rotary motor 34 is connected to a rotary encoder 35, which is connected to the control module 2 for obtaining parameters of the rotary motor 34. After processing the data, the control module 2 controls the operation of the rotary motor 34 to achieve control of the rotation speed and number of rotations of the bracket 1.

[0067] Reference Figure 1 and Figure 3-4 As shown, the clamping mechanism 4 includes a clamping frame 47, two clamps 41 and a clamping drive mechanism. The clamping frame 47 is fixedly connected to the bracket 1, and the two clamps 41 are connected to the clamping frame 47. The two clamps 41 can move synchronously toward or away from each other along a second direction. The second direction is perpendicular to the rotation axis of the bracket 1 rotating around the wire, and is suitable for clamping the wire through the two clamps 41. A plurality of guide protrusions 411 are provided on the sides of the two clamps 41 that are close to each other. When the two clamps 41 clamp the wire, the plurality of guide protrusions 411 are distributed in a spiral shape that surrounds the outside of the wire and extends along the axial direction of the wire, and are suitable for contacting the wire through the guide protrusions 411. When the two clamps 41 rotate around the wire, the clamps 41 are driven to move along the axial direction of the wire through the guide protrusions 411. The clamping drive mechanism connects the clamping frame 47 and the two clamps 41, and is used to drive the two clamps 41 to move synchronously toward or away from each other. The clamping drive mechanism is connected to the control module 2.

[0068] Reference Figure 1 and Figure 3 As shown, specifically, the two clamps 41 are distributed on the bracket 1 on both sides of the axis of the gear ring 31, and the second direction is perpendicular to the axis of the gear ring 31. The wire passes through the gap of the gear ring 31 and is located between the two clamps 41 at the same time. When the two clamps 41 clamp the wire, the guide protrusion 411 on the clamps 41 contacts and abuts against the wire. Since the multiple guide protrusions 411 on the two clamps 41 are distributed in a spiral shape that surrounds the wire and extends axially along the wire, when the rotary drive mechanism 3 drives the bracket 1 to rotate around the wire, the friction force between the guide protrusion 411 and the wire generates a component force along the axial direction of the wire, and the component force is used to drive the bracket 1 to move axially along the wire, thereby realizing the function of the bracket 1 moving axially along the wire.

[0069] Reference Figure 3As shown, further, the clamping drive mechanism includes a bidirectional screw 42, a guide rod 43 and a clamping motor 44, the axis of the bidirectional screw 42 is perpendicular to the axis of the gear ring 31, the bidirectional screw 42 is rotatably connected to the clamping frame 47, the two clamps 41 are respectively threadedly connected to the two threaded sections of the bidirectional screw 42, the guide rod 43 is parallel to the bidirectional screw 42 and fixedly connected to the clamping frame 47, the guide rod 43 passes through the two clamps 41 to limit the rotation of the clamps 41, and the clamps 41 can move relative to the guide rod 43 along the axial direction of the guide rod 43, and the clamping motor 44 is fixedly connected to the clamping frame 47 to drive the bidirectional screw 42 to rotate. When the clamping motor 44 is started, the bidirectional screw 42 is driven to rotate, the clamp 41 is threadedly assembled with the bidirectional screw 42 and driven to move along the axial direction of the bidirectional screw 42 under the limiting action of the guide rod 43, so as to realize the synchronous movement of the two clamps 41 to approach or move away.

[0071] Reference Figure 3 As shown, specifically, the first trigger block passes through the clamp 41 connected to it and is partially located between the two clamps 41, a receiving box is fixed on the side of the clamp 41 away from the other clamp 41, the first sensor is arranged in the receiving box, the first trigger block extends into the receiving box, a limit rod is fixed in the receiving box, the axis of the limit rod is parallel to the axis of the guide rod 43, the first trigger block is movably sleeved on the limit rod, and a reset spring is sleeved on the limit rod, the two ends of the reset spring are abutted against the first trigger block and the receiving and bottom, so that the first trigger block is kept protruding between the two clamps 41 through the reset spring. When the wire is located between the two clamps 41 and the two clamps 41 are close to each other, the wire contacts the first trigger block and drives the first trigger block to move into the containing box. After the two clamps 41 clamp the wire in place, the first trigger block moves to be flush with the guide protrusion 411. At this time, the first trigger block triggers the first sensor to determine that the wire is clamped in place. After releasing the wire, the reset spring keeps the first trigger block protruding between the two clamps 41, so that it can be determined whether the wire is clamped in place the next time.

[0072] Reference Figure 3As shown, further, the clamping motor 44 is connected to a clamping encoder 45, and the clamping encoder 45 is also connected to the control module 2, so that the clamping encoder 45 detects the operating parameters of the clamping motor 44, and the operating data of the clamping motor 44 after the initial position of the clamp 41 and the clamped wire are in place, combined with the pitch and other parameters of the bidirectional screw rod 42, the wire diameter of the clamped wire can be obtained by processing the data through the control module 2.

[0073] Reference Figure 3 and Figure 5 As shown, the feed mechanism 5 is connected to the bracket 1 and rotates around the wire and moves along the axial direction of the wire with the bracket 1, including a cutter head 51, a feed drive mechanism and a detection module. The feed drive mechanism is used to drive the cutter head 51 to move to advance or retract the cutter. The detection module is used to detect whether the insulation layer behind the cutter head 51 along the travel path of the bracket 1 is stripped, and is used to detect whether the cutter head 51 is in contact with the wire core. The feed drive mechanism and the detection module are both connected to the control module 2, and are suitable for controlling the cutter head 51 to advance when the insulation layer is not stripped, and to control the cutter head 51 to retract when the cutter head 51 is in contact with the wire core.

The mounting block passes through the side wall of the opening of the knife holder 52, is sleeved on the feed screw rod, and is threadedly assembled with the feed screw rod. The mounting block fits the inner wall of the knife holder 52 to be restricted from rotating around the axis of the feed screw rod, so that when the feed motor 54 drives the feed screw rod to rotate, the mounting block can be driven to move along the first direction, driving the knife seat 53 and the knife head 51 to move; accordingly, a mounting hole for the knife head 51 to be installed is provided on the knife seat 53, and the knife head 51 is inserted into the mounting hole and locked on the knife seat 53 by bolts. When the clamp 41 clamps the wire, the knife head 51 can move along the first direction, and the feed screw rod is driven to rotate by the feed motor 54, so that the knife head 51 moves along the first direction to realize the control of feeding or retracting.

[0076] Reference Figure 5 As shown, the detection module includes a chip, a connecting circuit and an infrared photoelectric sensor 55. The connecting circuit connects the cutter head 51 and the chip, and the chip is connected to the control module 2. When the cutter head 51 contacts the wire core, the chip transmits a signal to the control module 2 through the chip. The infrared photoelectric sensor 55 is connected to the cutter head 51 and is used to be distributed with the cutter head 51 along the radial direction of the wire. The infrared photoelectric sensor 55 is located behind the cutter head 51 in the direction of travel of the bracket 1. The infrared photoelectric sensor 55 is used to detect the surface color of the wire behind the travel path of the cutter head 51 to determine whether the insulation layer is stripped off.

[0077] Specifically, the cutter head 51 includes a first blade and a second blade, and the first blade and the second blade are spaced apart along the axial direction of the gear ring 31. The chip connects the first blade and the second blade through a connecting line, and is suitable for transmitting a signal to the control module 2 through the chip when both the first blade and the second blade are in contact with the wire core. The gap between the first blade and the second blade is filled with an insulator to isolate the first blade and the second blade. The insulator is made of an insulating material that is not easily broken down. When only one blade forms a connected circuit with the wire core, the circuit between the first blade and the second blade is broken, and the chip is not triggered. That is, when a path is formed between any blade and the wire core due to various situations such as the air between the cutter head 51 and the wire core being broken down, the cutter head 51 touching the semi-conductive layer, or a foreign object falling into the gap, the chip will not be triggered. Only when both the first blade and the second blade form a path with the wire core, a path is formed between the first blade and the second blade to trigger the chip. At this time, it is judged that the cutter head 51 is in contact with the wire core, thereby reducing the probability of the chip being triggered by mistake, and avoiding the undesirable phenomenon of frequent withdrawal of the cutter resulting in unclean stripping of the insulation layer.

[0078] Since the colors of the insulation layer and the wire core are different, the control module 2 can determine whether the wire core is exposed, that is, whether the insulation layer is stripped, based on the reflected light received by the infrared photoelectric sensor 554, and control the cutter head 51 to advance when the insulation layer is not stripped, thereby ensuring that the insulation layer is stripped. The detection module can be used to determine in real time whether the position of the cutter head 51 is in a reasonable position, and adjust the advance amount in time when the advance amount of the cutter head 51 is too small or too large, to avoid the cutter head 51 advancing too much to damage the core or too little to prevent the insulation layer from not being stripped.

[0079] Reference Figure 5 As shown, further, the feed motor 54 is connected to a feed encoder 56, and the feed encoder 56 is also connected to the control module 2. The feed encoder 56 obtains the operating parameters of the feed motor 54, and the controller can obtain the feed amount data of the cutter head 51 based on the detection data of the feed encoder 56 and in combination with the pitch of the feed screw; in the initial operation, combined with the initial position of the cutter head 51 and the wire diameter data, the idle stroke of the cutter head 51 can be calculated so that the cutter can be quickly fed to contact the insulation layer of the wire, and the thickness of the insulation layer can be calculated according to the total stroke, idle stroke and feed amount of the cutter head 51 when the insulation layer is stripped, so as to control the parameters such as the stripper travel operating speed and the cutter head 51 feed speed according to the parameters of the wire and the insulation layer, so as to realize stepless speed operation and dynamic cutting control for wires with different wire diameters and different insulation layer thicknesses, thereby improving operation efficiency while ensuring safety. The control module 2 also controls the feed amount data after subsequent feed or retraction based on the feed amount data each time the cutter head 51 contacts the wire core or the insulation layer is not stripped off, so as to keep the feed amount within a reasonable range that does not damage the core but can strip off the insulation layer.

[0080] Furthermore, in order to improve the accuracy of feed amount control, an origin reset sensor is fixed on the tool holder 52, and a second trigger block 46 is set on the tool seat 53 to trigger the origin reset sensor. When the cutter head 51 retracts to the initial position, the second trigger block 46 triggers the origin reset sensor, and the encoder resets to the origin to correct the feed amount data of the cutter head 51, that is, the peeler is corrected every time it works, eliminating the accumulated error to ensure the accurate control of the feed amount of the cutter head 51.

[0081] Reference Figure 1 As shown, further, a skin outlet shell 57 is connected to the knife holder 52, which is located in front of the moving direction of the knife head 51 and includes a skin inlet and a skin outlet. The skin inlet is close to the knife head 51, and the skin outlet is located at the end of the knife head 51 away from the wire. The insulation layer stripped by the knife head 51 enters the skin outlet shell 57 from the skin inlet and is output from the skin outlet. In this way, the stripped insulation layer can be kept away from the wire, avoiding the stripped insulation layer from being entangled on the wire and affecting the moving stripping operation of the stripper.

[0082] Reference Figure 1-2 and Figure 6 As shown, the safety protection device includes a detection roller 61 and a first detection member. The axis of the detection roller 61 is parallel to the rotation axis of the bracket 1 rotating around the wire, and the detection roller 61 can rotate around its axis relative to the bracket 1. The detection roller 61 is used to abut against the wire, and when the bracket 1 rotates around the wire, the friction between the wire and the detection roller 61 drives the detection roller 61 to rotate relative to the bracket 1. The first detection member is connected to the detection roller 61 and detects the rotation rate of the detection roller 61 around its axis relative to the stripper. The first detection member is connected to the control module 2 and is suitable for controlling the rotary drive mechanism 3 to stop running through the control module 2 when the rotation rate is lower than a set threshold.

[0083] Reference Figure 6 As shown, the detection roller 61 is connected to the bracket 1 through a connecting structure, the connecting structure connecting shaft 63, connecting frame 64 and elastic member, the connecting shaft 63 is connected to the bracket 1 and its axis is parallel to the rotation axis of the bracket 1 rotating around the wire, and the axis of the connecting shaft 63 and the axis of the detection roller 61 and the rotation axis of the bracket 1 rotating around the wire are all arranged at intervals, the connecting frame 64 is connected to the detection roller 61 connecting shaft 63, the connecting frame 64 can rotate relative to the connecting shaft 63 around the axis of the connecting shaft 63, and the detection roller 61 can rotate relative to the connecting rod around its axis, the elastic member connects the connecting frame 64 and the connecting shaft 63, in the process of the bracket 1 being connected to the wire, the detection roller 61 is abutted against the wire, and the wire drives the detection roller 61 to rotate around the connecting shaft 63 to overcome the elastic force of the elastic member.

[0084] Reference Figure 6As shown, specifically, the axis of the detection roller 61 is parallel to the axis of the gear ring 31, and the detection member includes a detection encoder 62, which is fixed on the connecting frame 64 and its rotation axis is coaxially fixed with the detection roller 61, so that the rotation rate of the roller 61 can be detected by the detection encoder 62, and the control module 2 calculates the rotation rate of the bracket 1 relative to the wire according to the detection data of the detection encoder 62. The elastic member includes a holding spring 65, and its two ends are respectively fixed to the connecting shaft 63 and the connecting frame 64, so that the detection roller 61 is pressed against the wire when the detection roller 61 is pressed against the wire.

[0085] Through the above arrangement, when the bracket 1 is connected to the wire, the detection roller 61 is in contact with the outer skin of the wire. When the detection roller 61 rotates around the wire with the bracket 1, the friction between the wire and the detection roller 61 drives the detection roller 61 to rotate relative to the bracket 1. During the stripping operation, the rotation rate of the detection roller 61 relative to the bracket 1 is proportional to the rotation rate of the bracket 1 relative to the wire. The detection encoder 62 cooperates with the control module 2 to detect the rotation rate of the detection roller 61 relative to the bracket 1 to reflect the rotation rate of the bracket 1 relative to the wire. During normal operation, when the bracket 1 and the wire rotate relative to each other, the rate is maintained within a certain range. When the wire rotates with the bracket 1, the relative rotation rate between the wire and the bracket 1 is reduced. When it is reduced to below the set value, it indicates that the wire rotates with the bracket 1 to a large extent and the wire is twisted to a large extent. At this time, in order to avoid damaging the wire, the control module 2 controls the rotary drive mechanism 3 to stop running and stop the stripping operation to protect the wire and avoid safety accidents.

[0086] In this embodiment, the peeler includes a shell, which includes various electrical components and circuits, etc. The control module 2 is inside the shell and installed on the shell. The control module 2 is connected to the various electrical components through circuits. The shell can protect the various electrical components and make the appearance of the entire peeler more beautiful.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
