Description

Technical Field

[0001] The present invention relates to the technical field of wire maintenance equipment, and particularly to an automatic stripping device for the aluminum wire core and insulating layer of a wire. Background Art

[0002] When connecting wires, it is necessary to strip the wires. When the traditional wire skin rapid stripping device strips the wires, generally a manual wire stripper is used. However, using a wire stripper is labor-intensive and time-consuming, and it is difficult to strip, resulting in low work efficiency. In some live working situations, workers need to have high professional skills, and the labor cost is relatively high.

[0003] For example, the Chinese patent discloses "An overhead insulated wire outer skin stripping device" (Patent No.: CN201710010174.X), which consists of a stripping head assembly, an insulated transmission assembly, and an insulated rod operation assembly connected in sequence. When using the overhead insulated wire outer skin stripping device, there is no need to cut off the power supply of the operating high-voltage overhead distribution line, and workers can perform stripping operations live, and workers do not need to carry other auxiliary tools. Therefore, workers can perform live connection of diversion wires on the overhead distribution line. The above patent has the characteristics of good safety, convenient use, simple operation, and wide application range.

[0004] However, the above stripping device only ensures live working of workers by passing current through the lead wire, and still requires workers to directly contact the live wire, which has potential safety hazards and is relatively dangerous to use. Summary of the Invention

Detailed implementation mode

[0027] An embodiment of the present invention provides an automatic stripping device for the aluminum wire core and the insulating layer of a wire, as Figures 1-5 shown, which includes a housing 11, two groups of slide rails 13, two groups of connectors 16, a stripping arm 17, a pressing mechanism, a lifting beam 33 and a clamping mechanism. An insulating rubber layer is sleeved on the outer surface of the housing 11, as Figure 2 shown. A stripping cavity 12 is opened in the housing 11. Two wire grooves 40 are communicated on both sides of the stripping cavity 12. Two fixing platforms 20 are arranged below the stripping cavity 12. The two fixing platforms 20 are respectively fixed on both sides of the inner wall of the stripping cavity 12. The two fixing platforms 20 are respectively located on both sides of the wire groove 40. Two groups of slide rails 13 are respectively fixed on the upper ends of the fixing platforms 20. The two groups of slide rails 13 are symmetrically arranged. The slide rail 13 includes a vertical guiding channel on the upper side and an arc guiding channel on the lower side. A first sliding block 14 and a second sliding block 15 are slidably arranged in each group of slide rails 13. The first sliding block 14 is located above the second sliding block 15, as Figure 5 shown. Two groups of connectors 16 are respectively fixedly connected to the front sides of the first sliding block 14 and the second sliding block 15. The stripping arms 17 are respectively fixed on the end faces of the two groups of connectors 16 close to each other. The lifting beam 33 is arranged above the two groups of connectors 16. The pressing mechanism is arranged above the two groups of connectors 16. The pressing mechanism is used to control the lifting of the lifting beam 33 to move the connectors 16 up and down. The lifting beam 33 and the connectors 16 are both provided with magnetism. The clamping mechanism is arranged in the fixing platform 20. The clamping mechanism is used to move the housing 11 along the insulating layer on the outer side of the wire.

[0028] It should be noted that the contact surface between the lifting beam 33 and the connector 16 is an arc surface. The arc surface of the lifting beam 33 at both ends on the side of the connector 16 is lower than the center end of the connector 16. Therefore, during the descending process, it assists the connectors 16 on both sides to swing.

[0029] The first sliding block 14 and the second sliding block 15 have the same shape. The axial two sides of the first sliding block 14 and the second sliding block 15 respectively extend to the outside of the slide rail 13 and are provided with fixed ends larger than their radii. The fixed ends on the axial two sides of the first sliding block 14 and the second sliding block 15 limit the axial movement in the slide rail 13. Since the second sliding block 15 is located below the first sliding block 14, when the connector 16 drives the first sliding block 14 and the second sliding block 15 to slide down synchronously, the second sliding block 15 is located in the arc guiding channel of the slide rail 13, and the first sliding block 14 is located in the vertical guiding channel of the slide rail 13. At this time, the second sliding block 15 inclines the connector 16, so that the distance between the two connectors 16 on both sides gradually increases from top to bottom.

[0030] The magnetic poles between the two sets of connectors 16 and the lifting beam 33 are of opposite polarity. The lifting beam 33 drives the two sets of connectors 16 to descend synchronously by pressing down, and drives them to return to the initial position synchronously by magnetic force when rising.

[0031] As Figure 3 shown, the pressing mechanism includes a lead screw 30, a knob 31 and a lifting block 32. The lifting block 32 is fixedly connected to the lifting beam 33. The lead screw 30 is arranged in the housing 11 and rotatably connected to the upper surface of the lifting block 32. The outer cylindrical surface of the lead screw 30 is threadedly connected to the housing 11. The upper end surface of the lead screw 30 extends to the upper side of the housing 11, and the knob 31 is fixedly arranged on the upper surface of the lead screw 30.

[0032] As Figure 4 shown, the clamping mechanism includes a sliding box 21, rollers 23 and elastic members. The sliding boxes 21 are respectively slidably arranged in the fixed platforms 20 on both sides. Roller chambers 22 are respectively opened in the sliding boxes 21. The rollers 23 are respectively rotatably connected in the roller chambers 22. The elastic members are arranged between the sliding boxes 21 and the inner walls of the fixed platforms 20.

[0033] The rollers 23 are rotatably connected between the upper and lower walls of the roller chambers 22. A roller groove 24 adapted to the cross-section of the wire is formed on the outer cylindrical surface of the rollers 23.

[0034] As Figure 3 and 5 shown, the wire stripping arm 17 is arc-shaped, the shape of the wire stripping arm 17 is a minor arc, one end of the arc of the wire stripping arm 17 is connected to the connector 16, and the other end of the arc of the wire stripping arm 17 faces the lower side inside the stripping cavity 12.

[0035] A stripping rod 18 is slidably arranged in the wire stripping arm 17. A telescopic spring is connected between the stripping rod 18 and the inner side of the wire stripping arm 17. When the second sliding block 15 moves to the boundary between the arc-shaped guide and the vertical guide in the slide rail 13, the lower end of the stripping rod 18 is at the same height as the upper surface of the roller 23.

[0036] The number of the stripping rods 18 corresponds to that of the wire stripping arms 17. Grooves adapted to the outer surface of the wire are provided on the lower end surfaces of the two sets of stripping rods 18.

[0037] In the initial state, the lifting beam 33 is located at the upper limit position. The first sliding block 14 and the second sliding block 15 are both located in the vertical guide of the slide rail 13, so that the connectors 16 on both sides are in a vertical state. The sliding boxes 21 on both sides are in a state of approaching each other under the elastic force of the elastic members. The staff first cuts the lengths on both sides of the part of the wire to be stripped, and then uses an electrician's knife to slide along the axial surface at an angle of 45° to the wire, so that scratches are generated on the outer rubber insulation layer of the wire and the insulation layer is not completely cut through.

[0038] After aligning the wire with the wire grooves 40 on both sides, the operator manually presses the wire between the two rollers 23 on both sides. At this time, the wire increases the distance between the two rollers 23 on both sides, and the two rollers 23 drive the two sliding boxes 21 on both sides to move away from each other and slide relative to each other within the fixed table 20, thereby compressing the elastic member within the fixed table 20, so that the wire abuts against the roller groove 24, thereby completing the clamping and fixing and making the wire scratch directly face the center of the two stripping rods 18.

[0039] After the wire is fixed, the operator manually rotates the knob 31. The knob 31 drives the lead screw 30 to rotate. The lead screw 30 drives the lifting block 32 to move downward through the external thread on its surface. The lifting block 32 drives the two connecting heads 16 on both sides to move downward through the lifting beam 33. The two connecting heads 16 drive the first sliding block 14 and the second sliding block 15 to slide downward synchronously along the slide rail 13. When the second sliding block 15 is located within the arc guiding path of the slide rail 13 and the first sliding block 14 is located within the vertical guiding path of the slide rail 13, the two connecting heads 16 are inclined, so that the outer cutting surfaces of the two stripping arms 17 move relative to each other and drive the lower stripping rods 18 to move away from each other. At this time, the lower groove of the stripping rod 18 abuts against the outer insulating layer of the wire and compresses the telescopic spring within the stripping arm 17. At this time, the telescopic spring applies pressure to the outer insulating layer of the wire, causing the outer insulating layer of the wire to tear along the scratch. At the same time, the operator manually pushes the housing 11 to move the housing 11 along the surface of the wire. At this time, due to the frictional force, the roller 23 rotates relative to the wire, and the stripping rod 18 continuously applies force to the outer insulating layer of the wire to expose the inner aluminum wire core along the scratch, thereby completing the stripping. After the stripping is completed, the operator manually reverses the rotation of the knob 31. The knob 31 drives the lifting beam 33 to rise back to the initial position, and then drives the connecting head 16 to return to the initial position through the magnetic force.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
