Description

Technical Field

[0001] The invention relates to the technical field of power transmission line construction, and in particular to a conductive grease coating machine for wire crimping. Background Art

[0002] During transmission line stringing construction, hydraulic conductor connections are required, one of which involves applying conductive grease. Currently, this process is performed manually using a fine wire brush. First, the wire brush removes oxides from the aluminum strands and increases the surface roughness of the crimped portion. Then, conductive grease is applied and evenly applied with the wire brush. The quality of this process varies depending on individual operator factors, potentially affecting connection strength. Furthermore, the process is inefficient, impacting overall payout efficiency. Therefore, improving the efficiency of applying conductive grease is crucial for improving the efficiency of tension payout construction. Summary of the Invention

DETAILED DESCRIPTION

[0060] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the relevant content and are not intended to limit the present invention.

[0061] It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings.

A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0064] In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0065] like Figure 1 As shown, a conductive grease coating machine for crimping a wire 100 includes a base plate 1, a slide, a fixture assembly 4, a coating assembly 6 and a controller.

[0066] The base plate 1 is a rectangular plate with multiple groups of round holes on it, and the fixture assembly 4, slide and control box and other components can be installed by bolts. The connection described in this embodiment can be achieved through various connection methods such as bolt connection, welding connection, screw connection, etc., which will not be repeated in the following.

[0067] The slide includes a slide body 2 and a slide moving seat 3. The slide body 2 is installed on the base plate 1. The slide moving seat 3 is slidably connected to the slide body 2. The painting brush component 6 is installed on the slide moving seat 3. The movement of the painting brush component 6 is controlled by the slide moving seat 3 sliding along the slide body 2.

[0068] The clamp assembly 4 is arranged at one end of the slide body 2 and is installed on the base plate 1. The clamp assembly 4 applies a clamping force to the wire 100 strands; the wire 100 is fixed by the clamp assembly 4, and then the slide drives the coating assembly 6 to move along the axis of the wire 100, so that the conductive grease can be coated on the aluminum strand surface of the wire 100, thereby realizing the coating of the conductive grease.

[0069] The control box is installed on the base plate 1, and the control box has a built-in controller, which is electrically connected to the slide and the brush assembly 6; the slide and the brush assembly 6 can be controlled by the controller, and the controller can adopt a conventional industrial control box at this stage, for example: there are three control keys on the outside of the control box, namely a start button, a carry button, and an abdicate button. The start button controls the power supply of the driver and the controller. When the carry button is triggered, the slide moving seat 3 moves away from the control box. When the abdicate button is triggered, the slide moving seat 3 moves toward the control box.

[0070] The control box contains a CNC motor, controller, driver, and power supply. The output shaft of the CNC motor is connected to the end of the slide screw. The controller and driver jointly control the operation of the CNC motor.

[0071] That is, the relative position of the coating component 6 and the conductive wire 100 can be changed, thereby enabling the conductive grease to be coated on the conductive wire 100 .

[0072] Example 1

[0073] This embodiment describes the specific structure of the slide.

[0074] The slide body 2 comprises a rectangular parallelepiped component, a screw rod, a screw nut and a CNC motor. As a preferred solution, the screw rod, the screw nut, the screw nut fixing seat and the screw fixing seat can all be built into the rectangular parallelepiped component.

[0075] The rectangular parallelepiped component is fixed on the base plate 1 , and the central axis of the rectangular parallelepiped component is parallel to the central axis of the clamp assembly 4 . Therefore, after the wire 100 is fixed on the clamp assembly 4 , the central axis of the wire 100 is parallel to the central axis of the rectangular parallelepiped component.

[0076] The screw rod is arranged along the central axis of the rectangular component, and the screw rod is fixed in the rectangular component through a support seat; the screw nut is sleeved on the screw rod and is threadedly connected to the screw rod, and the screw nut is fixedly connected to the slide movable seat 3; therefore, the moving direction of the slide movable seat 3 coincides with the central axis direction of the wire 100.

[0077] The torque output end of the CNC motor is dynamically connected to the torque input end of the lead screw. The controller controls the rotation of the CNC motor to control the threaded screw structure, thereby controlling the slide moving seat 3. The working principle of the slide is that the output shaft of the CNC motor rotates to drive the lead screw to rotate, and the rotation of the lead screw drives the lead screw nut to move horizontally. The slide moving seat 3 is fixed to the lead screw nut, and the movement of the lead screw nut drives the movement of the slide moving seat 3.

[0078] In addition, in order to avoid the damage of the entire device caused by the over-range movement of the slide movable seat 3, as shown in FIG. Figure 1 As shown, the slide in this embodiment further includes a first limit switch 21 and a second limit switch 22 .

[0079] The first limit switch 21 and the second limit switch 22 are both installed on the side of the rectangular parallelepiped component, and the slide moving seat 3 is installed with a sensor plate 23 adapted to the first limit switch 21 and the second limit switch 22;

[0080] The numerically controlled motor, the first limit switch 21 and the second limit switch 22 are all electrically connected to the controller.

[0081] By installing the induction plate 23 on the slide movable seat 3, when the first limit switch 21 or the second limit switch 22 detects that the slide movable seat 3 has moved to the set position, the first limit switch 21 and the second limit switch 22 will send an in-position signal to the controller, and the controller will control the CNC motor to stop, thereby avoiding the situation of over-limit movement.

[0082] The resulting painting range is between the first limit switch 21 and the second limit switch 22. Therefore, in order to achieve control of the painting range, a slide groove 24 parallel to the screw is provided on the side of the rectangular component, and a sliding slider is provided in the slide groove 24. The first limit switch 21 and the second limit switch 22 are slidably connected to the rectangular component through the slider.

[0083] By changing the positions of the first limit switch 21 and the second limit switch 22 on the rectangular parallelepiped component, the painting range can be changed.

[0084] And it can be seen from the figure that the connection between the limit switch and the slider is achieved by screws and the like.

[0085] Example 2

[0086] like Figure 1 and Figure 2 As shown, the position of the wire 100 needs to be fixed by a clamp assembly 4 , and the clamp assembly 4 includes a support 41 , a fixing member 43 and a movable member 42 .

[0087] The lower end of the support 41 is connected to the base plate 1, and the upper end of the support 41 is located above the slide body 2; the support 41 is a profile and can be made of square tubes, round tubes, or angle steels. In this embodiment, a section of channel steel is cut to make it, and end plates are welded to the upper and lower sections of the channel steel. The lower end plate is used to connect to the base plate 1, and the upper end plate is used to connect to the fixing part 43.

[0088] The fixing member 43 is fixedly connected to the upper end of the support 41, and one end of the movable member 42 is rotatably connected to one end of the fixing member 43. The fixing member 43 and the movable member 42 can form a circular ring structure, and the central axis of the clamp assembly 4 is parallel to the central axis of the slide body 2;

[0089] The quick clip 44 is a mature product. The conventional quick clip 44 has a locking hook and a base. The locking hook of the quick clip 44 is connected to the other end of the fixed part 43, and the base of the quick clip 44 is connected to the other end of the movable part 42.

[0090] When in the clamping state, the movable member 42 applies a force to the wire 100 toward the fixed member 43 , and the movable member 42 and the fixed member 43 clamp the wire 100 in the clamp assembly 4 .

[0091] In order to clamp the wires 100 of different diameters, the clamp assembly 4 in this embodiment further includes a fixed inner sleeve 46 and a movable inner sleeve 45 .

[0092] The outer annular surface of the fixed inner sleeve 46 is detachably connected to the inner annular surface of the fixing member 43 through a dovetail groove and a dovetail strip; in this embodiment, the dovetail strip is set on the outer annular surface of the fixed inner sleeve 46, and the dovetail groove is set on the inner annular surface of the fixing member 43.

[0093] The outer annular surface of the movable inner sleeve 45 is detachably connected to the inner annular surface of the movable part 42 through a dovetail groove and a dovetail strip. In this embodiment, the dovetail strip is provided on the outer annular surface of the movable inner sleeve 45 and the dovetail groove is provided on the inner annular surface of the movable part 42 .

[0094] The radii of the fixed inner sleeve 46 and the movable inner sleeve 45 are equal and equal to the diameter of the wire 100 to be painted.

[0095] That is: the main body of the fixing part 43 is a semicircular arc structure, and the inner wall of the arc opening is parallel to the axial direction and provided with a dovetail groove which matches the dovetail strip on the fixed inner bushing 46, so that the fixed inner bushings 46 of different specifications can be installed into the fixing part 43. The front and back sides of the arc are planes of a certain width, and 4 screw holes are provided in the center of the plane, which are aligned with the 4 through holes at the upper end of the support 41 and fixed to the support 41 by bolts. One end of the arc opening is a connecting ear for connecting the movable part 42. A part of the middle part of the connecting ear is removed so that the connecting ear of the movable part 42 is placed in the connecting ear to realize the coaxial connection of the connecting ears of the two components. The side of the other end is set to a plane, and two screw holes are provided on the plane for fixing the locking hook of the quick clamp 44.

[0096] The main body of the movable part 42 is also a semicircular arc mechanism. The inner wall of the arc opening is parallel to the axial direction and a dovetail groove is set to match the dovetail strip on the movable inner sleeve 45 to meet the needs of installing movable inner sleeves 45 of different specifications into the movable part 42. One end of the arc end is a connecting ear for connecting the movable part. A part of the two ends of the connecting ear is removed so that the connecting ear of the fixing part 43 can be placed in to realize the coaxial connection of the connecting ears of the two components. The side surface of the other end is set to a plane, and two screw holes are set on the plane for fixing the base of the quick clamp 44.

[0097] The quick clamp 44 is a mature product. Its locking hook is mounted on the fixed part 43, its base is mounted on the movable part 42, and its handle is hinged to a raised connection hole in the center of the base. A long U-bolt is connected to the handle's rotating shaft. Adjusting the bolts on either side of the U-bolt's connection to the shaft changes the exposed length of the U-bolt, thereby varying the clamp's grip on the wire 100. The U-bolt hooks onto the locking hook, and turning the handle opens and closes the clamp's fixed part 43 and movable part 42, tightening or loosening the wire 100.

[0098] Example 3

[0099] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the painting assembly 6 in this embodiment includes a frame 61, an extrusion assembly 7 and a brush body assembly.

[0100] The frame 61 is connected to the slide movable seat 3. The frame 61 is the entire skeleton of the brush assembly 6. In order to install the brush assembly, a large circular hole 611 and a small circular hole 612 are set in the frame 61.

[0101] The extrusion assembly 7 is connected to the frame 61 and extrude conductive grease onto the aluminum strand surface of the conductor 100. In this embodiment, the extrusion assembly 7 includes a fixing ring and an extruder. The fixing ring is fixedly connected to the frame 61 and fixes the conductive grease box 200 above the conductor 100, and the outlet of the conductive grease box 200 is located directly above the conductor 100; the extruder is connected to the frame 61 and applies an extrusion force to the conductive grease box 200 to squeeze out the conductive grease in the conductive grease box 200. The extruder is electrically connected to the controller.

[0102] The squeezer is a common extrusion device currently available. For example, in this embodiment, the conductive grease box 200 is packaged in a toothpaste-like manner, and the conductive grease can be squeezed out using a device similar to an automatic toothpaste squeezer. Alternatively, an electric push rod can be provided to apply force to the conductive grease box 200 located within the fixed ring by extending the electric push rod, thereby squeezing out the conductive grease.

[0103] The brush assembly is connected to the frame 61 , and when in operation, the brush assembly contacts the surface of the wire 100 passing through the frame 61 .

[0104] The brush body assembly includes a large gear 62, a small gear 63, a numerically controlled motor and a steel brush assembly.

[0105] A coaxial large ring 621 is fixedly provided on one side of the large gear 62 . The large ring 621 is arranged in the large circular hole 611 and is rotatably connected to the large circular hole 611 through a large bearing. The wire 100 is coaxially arranged with the large gear 62 and passes through the center hole of the large gear 62 .

[0106] When installing the large gear 62, the inner wall of the large circular hole 611 is tightly matched with the outer wall of the outer ring of the large bearing. The large circular hole 611 of the frame body 61 is provided with evenly distributed screw holes on both sides near the inner wall. Bolts are screwed into the screw holes on both sides to support the outer ring of the large bearing, thereby constraining the large bearing in the large circular hole 611.

[0107] The cross section of the large ring 621 is evenly distributed with three screw holes, and bolts are screwed into the three screw holes, so that the inner ring of the large bearing and the large gear 62 are connected as one. Under the action of the large bearing, the large gear 62 can rotate smoothly in the large circular hole 611.

[0108] A coaxial extension shaft 631 is fixedly provided on one side of the small gear 63. The extension shaft 631 is disposed in the small circular hole 612 and is rotatably connected to the small circular hole 612 via a small bearing. The large gear 62 is meshed with the small gear 63.

[0109] Small circular hole 612 houses a small bearing. One side of this hole has a rib that blocks the outer ring of the small bearing, while the other side has a slot for a retaining ring that fits into the hole. The extended shaft 631 of pinion gear 63 fits tightly against the inner ring of the small bearing. A retaining ring fits into the slot at the outer end of the extended shaft 631, blocking the inner ring. A small hole is drilled perpendicular to the axial direction on the tooth surface of pinion gear 63. Pinion gear 63 is inserted into the torque output shaft of the CNC motor, and a pin is driven into the hole, connecting the two shafts together and preventing them from falling off.

[0110] The torque output end of the numerical control motor is electrically connected to the torque input end of the small gear 63 ; the steel brush assembly is connected to the large gear 62 , and when working, the bristles of the steel brush assembly are in contact with the wire 100 .

[0111] The small gear 63 is driven to rotate by a numerically controlled motor, and the large gear 62 is rotated through gear meshing, so that the steel brush assembly connected to the large gear 62 rotates around the wire 100, thereby achieving the purpose of evenly applying the conductive grease on the wire 100.

[0112] Therefore, in order to achieve uniform coating of the conductive grease, the steel brush assembly in this embodiment includes a centrifugal hammer 64 and a roller brush 65 .

[0113] The centrifugal hammer 64 has a heavy end 641, a light end 643 and a middle section 642. The middle section 642 of the centrifugal hammer 64 is rotatably connected to the large gear 62 via a rotating shaft. The rotation plane of the centrifugal hammer 64 is parallel to the rotation plane of the large gear 62. When the large gear 62 rotates, under the action of centrifugal force, the heavy end 641 of the centrifugal hammer 64 will move outward, thereby causing the light end 643 of the centrifugal hammer 64 to move inward under the action of the lever.

[0114] The roller brush 65 is connected to the light end 643 of the centrifugal hammer 64 , and the roller brush 65 is disposed in the center hole of the large gear 62 , with the center axis of the roller brush 65 parallel to the center axis of the large gear 62 .

[0115] The conductor 100 is placed in the large gear 62, and the light end 643 of the centrifugal hammer 64 moves inward so that the roller brush 65 connected to the light end 643 contacts the conductor 100 to achieve coating.

[0116] In order to avoid the problem of center of gravity offset of the large gear 62, the number of centrifugal hammers 64 should be no less than two, and multiple centrifugal hammers 64 can be evenly distributed around the center of the large gear 62. For example, the number of centrifugal hammers 64 in this embodiment is 3. When the number of centrifugal hammers 64 is multiple, the number of other accessories connected to it should be changed accordingly.

[0117] In addition, in order to prevent the light end 643 of the centrifugal hammer 64 from being unable to reset and thus blocking the insertion path of the wire 100, the steel brush assembly also includes a reset spring 66, one end of the reset spring 66 is fixedly connected to the light end 643 of the centrifugal hammer 64, and the other end of the reset spring 66 is fixedly connected to the large gear 62. When the reset spring 66 is in its original length state, the distance between the roller brush 65 and the central axis of the large gear 62 is greater than the diameter of the wire 100.

[0118] When the large gear 62 rotates, the centrifugal force of the heavy end 641 of the centrifugal hammer 64 is greater than the sum of the centrifugal force of the light end 643 of the centrifugal hammer 64 and the elastic force of the return spring 66, thereby achieving the painting operation.

[0119] That is, when the large gear 62 does not rotate, the light end 643 of the centrifugal hammer 64 is reset under the elastic force of the reset spring 66 .

[0120] In addition, to prevent the centrifugal hammer 64 from excessively swinging and causing damage to the device, the steel brush assembly also includes a limit pin 67. The limit pin 67 is set on the swing trajectory of the heavy end 641 of the centrifugal hammer 64 and is connected to the large gear 62. That is, by setting the position of the limit pin 67, the maximum outward movement position of the heavy end 641 of the centrifugal hammer 64 is controlled.

[0121] like Figure 1 As shown, in order to increase the safety of the painting brush assembly 6, the painting brush assembly 6 further includes a protective cover provided on the outside of the frame 61 and the brush body assembly;

[0122] The protective cover is provided with an outlet hole for the wire 100 to pass through, and a funnel-shaped guide cover 68 is provided at the insertion end of the outlet hole. The guide cover 68 is provided with a notch for the conductive grease box 200 to pass through. When the wire 100 passes through the coating assembly 6, the wire 100 does not need to be completely aligned, and the guide cover 68 can play a guiding role.

[0123] Example 4

[0124] This embodiment provides operating methods of the above-mentioned multiple embodiments.

[0125] Level the ground at the crimping operation point, crimp the wire 100 and place it steadily along the line direction using a conductive grease coating machine.

[0126] Confirm whether the bushing on the clamp assembly 4 matches the specifications of the wire 100 to be crimped. If not, replace the corresponding fixed inner bushing 46 and movable inner bushing 45.

[0127] According to the length of the conductive grease applied, the positions of the first limit switch 21 and the second limit switch 22 are adjusted to determine the starting point and the ending point.

[0128] The wire 100 is passed through the clamp assembly 4 and the painting assembly 6 , and the quick clamp 44 is operated to enable the clamp assembly 4 to clamp the wire 100 .

[0129] After pressing the carry button, the device starts working, the extruder works to squeeze the conductive grease onto the wire 100; the CNC motor works to control the movement of the brush assembly 6; the CNC motor works to control the rotation of the large gear 62, so that the roller brush 65 contacts the wire 100, and the roller brush 65 starts to rotate at high speed around the axis of the wire 100 to brush the surface of the wire 100.

[0130] After completing the movement between the first limit switch 21 and the second limit switch 22 and finishing the painting, release the clamp assembly 4, withdraw the wire 100 and press the retreat button, and the painting assembly 6 retreats to the starting position and stops automatically.

[0131] Repeat the above operation to paint the next wire 100 .

[0132] The beneficial effects achieved by this device and this method are:

[0133] The present invention utilizes an extrusion box to extrude conductive grease onto the surface of the wire 100, replacing the traditional manual extrusion of conductive grease.

[0134] The centrifugal hammer 64 - return spring 66 structure ensures that the roller brush 65 can adaptively adhere to the surface of various specifications of wires 100 during high-speed rotation. The wire 100 has a wide range of adaptability, and the conductive grease has a good radial brushing effect, and it is also easy to achieve a consistent roughness on the surface of the wire 100.

[0135] The transmission structure of the slide is utilized to enable the slide movable seat 3 to move horizontally efficiently and stably, thereby ensuring the axial coating effect of the conductive grease.

[0136] The two limit switches can be flexibly adjusted to accommodate different conductor grease application lengths, while the inner sleeve of the conductor fixture can be replaced to accommodate different conductor diameters. The combination of these two greatly improves the adaptability of the equipment.
