Technical Field

[0001] The invention relates to the technical field of electric wire retraction and extension, and in particular to an electric wire retraction and extension device in the electric power industry. Background Art

[0002] In the power industry, wires refer to conductors that transmit electrical energy, which are divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires, and various profiles (such as profiled wires, busbars, copper bars, aluminum bars, etc.). They are mainly used for outdoor overhead and indoor busbars and switch boxes.

[0003] In the electric power industry, it is often necessary to use a wire retracting device to store the wires to prevent the wires from being too messy and affecting the use and transportation of the wires. In the prior art, the wire retracting device in the electric power industry can only retract the wires, but cannot clean the surface of the wires. The surface of the wires is stained with various stains and is easy to react with substances such as air and rain, which accelerates the aging and damage of the wires. In addition, it is difficult to ensure that the wires are reeled in evenly and tightly when reeling, and the reeling effect of the wires is poor. Therefore, a wire retracting device in the electric power industry is needed to meet the use needs. Summary of the invention

The wire roll will gradually become larger during the winding process. When the hole positions on the card block and the card slot coincide, the card block will be driven to engage in the card slot under the action of the guide telescopic rod. At this time, the abutment roller can be positioned without affecting the unwinding of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

The wire will move in the wire processing box 6 during the rewinding process. The wire cleaning mechanism 7 can clean the surface of the wire during the rewinding process to avoid the reaction between the stains on the wire surface and other substances to accelerate the aging of the wire and the damage of the outer skin.

The operator can open the valve body 79 and release and collect the cleaning liquid in the recovery box 76 through the drain pipe 78, and the cleaning liquid in the recovery box 76 can be recycled.

[0034] In the embodiment of the present invention, specifically, a hot air blower 710 is fixedly installed on the wire processing box 6, an air guide duct 711 is provided at the air outlet end of the hot air blower 710, a diverter 712 is fixedly installed on the air guide duct 711, and an exhaust pipe 713 is fixedly installed at the air outlet end of the diverter 712;

[0035] In order to heat and dry the cleaning liquid on the surface of the wire, the hot air blown by the hot air blower 710 will enter the diverter 712 under the guidance of the air guide 711, and will be diverted to multiple discharge pipes 713 through the diverter 712 and blown onto the wire, so as to heat and dry the cleaning liquid on the surface of the wire.

[0036] In the embodiment of the present invention, specifically, the wire driving mechanism 8 includes a second support plate 81 fixedly mounted on the base 1, a reciprocating screw 82 is rotatably mounted in the first support plate 2 and the second support plate 81, a screw sleeve 83 is sleeved on the reciprocating screw 82, a driving frame 84 is fixedly mounted on the top of the screw sleeve 83, and a contact round bar 85 is rotatably mounted in the driving frame 84;

[0037] In order to make the wires reel up smoothly, the reciprocating screw rod 82 rotates to drive the screw rod sleeve 83 to move left and right, and the left and right movement of the screw rod sleeve 83 drives the driving frame 84 to move left and right, and the left and right movement of the driving frame 84 causes the wires to be reciprocated on the wire reel 3 to be reeled up evenly, and the wires in the driving frame 84 directly contact the contact round bar 85 to avoid contact wear between the wires and the frame of the driving frame 84.

[0038] In the embodiment of the present invention, further, a screw sleeve 86 is fixedly installed at the bottom of the screw sleeve 83, and a guide rod 87 is fixedly installed on the first support plate 2 and the second support plate 81, and the screw sleeve 86 is slidably sleeved on the guide rod 87;

[0039] In order to guide the movement of the screw sleeve 83. The screw sleeve 86 slides on the guide rod 87 to guide the movement of the screw sleeve 83, so that the screw sleeve 83 can only move left and right on the reciprocating screw rod 82.

[0040] In the embodiment of the present invention, further, the ends of the wire retracting and unreeling reel 3 and the reciprocating screw rod 82 are fixedly sleeved with a transmission wheel 88, and a transmission belt 89 is movably sleeved on the transmission wheel 88;

[0041] In order to drive the reciprocating screw rod 82 to rotate. When the electric wire retracting and unreeling wheel 3 rotates, the transmission wheel 88 will be driven to rotate. Through the transmission effect of the transmission belt 89, the rotation of the transmission wheel 88 will drive the reciprocating screw rod 82 to rotate.

[0042] In the embodiment of the present invention, specifically, the wire conforming winding mechanism 10 includes an L-shaped bracket 101 arranged above the base 1, a mounting frame 102 is fixedly installed on the L-shaped bracket 101, an abutment roller 103 is rotatably installed on the mounting frame 102, a damping roller 105 is fixedly installed at the bottom of the L-shaped bracket 101, and the damping roller 105 is rollingly arranged in the guide rail 104;

[0043] In order to make the wires roll up snugly, the contact roller 103 abuts against the wires during the rolling process to make the wires roll up snugly and avoid large gaps in the wire rolls. The wire rolls will gradually get bigger during the rolling process. At this time, the contact roller 103 is squeezed to drive the L-shaped bracket 101 to move backwards. The backward movement of the L-shaped bracket 101 drives the damping roller 105 to roll backwards on the guide rail 104. When the wires are rolled up,

[0044] In the embodiment of the present invention, further, a block 106 is movably provided on the L-shaped bracket 101, a support block 107 is fixedly installed on the guide rail 104, a slot 108 is provided on the support block 107, and the block 106 and the slot 108 are adapted; a guide telescopic rod 109 and a telescopic spring 1010 are fixedly installed on the L-shaped bracket 101, and the other ends of the guide telescopic rod 109 and the telescopic spring 1010 are fixedly installed on the block 106;

[0045] In order to avoid affecting the unwinding of the wire after the wire is wound up, the contact between the clamping block 106 and the supporting block 107 will cause the compression and shortening of the guiding telescopic rod 109 and the telescopic spring 1010, and the telescopic spring 1010 can guide the movement of the clamping block 106, so that the clamping block 106 can only move forward and backward on the same straight line. When the holes on the clamping block 106 and the slot 108 coincide, the clamping block 106 will be driven to engage in the slot 108 under the action of the guiding telescopic rod 109, and the abutting roller 103 can be positioned at this time without affecting the unwinding of the wire.

[0046] Working principle: When in use, the wire to be wound enters the wire processing box 6 from between a set of cleaning rollers 71, and leaves the wire processing box 6 through a set of drying rollers 75, and then the wire is passed around the guide roller 9 and through the driving frame 84, and finally wound on the wire winding and unwinding reel 3. Start the drive motor 4, the rotation of the drive motor 4 will drive the wire winding and unwinding reel 3 to rotate, and the rotation of the wire winding and unwinding reel 3 will wind the wire. During the winding process, the wire will move in the wire processing box 6, and a set of drying rollers 75 will rotate and contact the wire to perform preliminary cleaning of the wire. Start the liquid outlet pump 73 and the hot air blower 710. On the one hand, the liquid outlet pump 73 will pump the cleaning liquid in the cleaning liquid tank 72 to the nozzle 74 for spraying, so as to spray and clean the wires and further remove the stains on the surface of the wires. The sprayed cleaning liquid will enter the recovery box 76 through the through hole at the bottom of the wire processing box 6. The filter screen 77 can filter the used cleaning liquid. The operating personnel can open the valve body 79 and release and collect the cleaning liquid in the recovery box 76 through the drain pipe 78, so that the cleaning liquid in the recovery box 76 can be recycled. The hot air blown by the hot air blower 710 will enter the diverter 712 under the guidance of the air guide duct 711, and will be diverted to multiple discharge pipes 713 through the diverter 712 and blown onto the wires, so as to heat the wires and dry the cleaning liquid contaminated on the surface of the wires. During the winding process of the wires, a group of drying rollers 75 will contact the surface of the wires to wipe the wires and wipe off the cleaning liquid that has not completely dried on the surface of the wires. In the process of winding the wires, the surface of the wires can be cleaned to avoid the reaction between the stains on the surface of the wires and other substances, which will accelerate the aging of the wires and the damage of the outer skin. When the wire retracting and unwinding reel 3 rotates, the transmission wheel 88 will be driven to rotate. Through the transmission action of the transmission belt 89, the rotation of the transmission wheel 88 will drive the reciprocating screw rod 82 to rotate. The screw rod sleeve 86 slides on the guide rod 87 to guide the movement of the screw rod sleeve 83, so that the screw rod sleeve 83 can only move left and right on the reciprocating screw rod 82, and then the rotation of the reciprocating screw rod 82 will drive the screw rod sleeve 83 to move left and right. The left and right movement of the screw rod sleeve 83 will drive the driving frame 84 to move left and right. The left and right movement of the driving frame 84 will cause the wire to be reciprocated on the wire retracting and unwinding reel 3, and the winding of the wire is more uniform. The wire in the driving frame 84 directly contacts the contact round bar 85 to avoid contact and wear between the wire and the frame of the driving frame 84.The elastic spring 1010 can guide the movement of the block 106 so that the block 106 can only move forward and backward on the same straight line. When the wire needs to be unwound, the driving motor 4 can be reversed, thereby driving the wire reel 3 to reverse, and the wire reel 3 can be reversed to unwind the wire. The operator can hold the push handle 12 and push the device, and the universal wheel 11 rolls and rotates on the ground to drive the device to move and adjust the moving direction of the device. The operation is relatively convenient and easy to use.
