Abstract

The utility model relates to an alligator wire take-up device, belonging to the technical field of the mechanical tools. The utility model is mainly composed of a box body, a gear wheel, a ratchet wheel, a ratchet pawl, a wheel shaft, a rack bar, and an alligator chuck. The utility model can be used for the wire take-up work at a high altitude in departments such as electric power department, communication department, etc., having the advantages of convenient assembly, convenient disassembly, time saving, labor saving, and high safety. The utility model can be used for not only the iron wire take-up work but also the steel wire take-up work.

Description

Alligatoring wire take-up device

The utility model relates to a kind of electric power, communication line sets up the crocodile formula wire grip of usefulness, belongs to the machine tool field.

At present, at the wire grip of fields such as electric power, communication use, normally reach the purpose of stringing to reduce the distance around iron wire.This wire grip is when built on stilts stringing operation, and operating personnel's health need lean out forward, needs before the stringing wire grip afterbody iron wire is wound, but in operating process, the iron wire afterbody is easily opened easily broken, and is very dangerous, and the iron wire afterbody is on fixing point, and mounting or dismounting are wasted time and energy.This wire grip is tightly iron wire, tightly steel wire also.

The purpose of this utility model is to overcome the weak point of above-mentioned wire grip, provides a kind of simple in structure, easy accessibility, and afterbody is fixed, and is safe and reliable, laborsaving saving time, iron wire, the general crocodile formula wire grip of steel wire.

The utility model is achieved in that crocodile formula wire grip comprises crocodile head and tooth bar two parts.The crocodile head is to be made of casing, gear, ratchet, ratchet, wheel shaft and anchor clamps, its anchor clamps are to constitute by carving piece, dovetail geosynclinal block and holder line piece, carving piece inserts in the dovetail geosynclinal block, be slidingly connected with banking pin, dovetail geosynclinal block and casing weldering are one, be positioned at an outside of casing, holder line piece is connected by screw with bottom half.On the cuboid wheel shaft that in another outside of casing and casing, has ratchet and gear to be fixedly mounted on respectively to pass casing, there are pad and pin fastening by the axle tip outside the ratchet.Ratchet is rotatably connected on casing by screw and spring, and with the tight interlock of ratchet.Tooth bar pass in the casing bottom and and gears engaged, an end of tooth bar is provided with gib head, the other end is spacing screw perforation.Operation principle is rotatable gear of rotating axle and the rotation of ratchet inhour, because the wheel and rack engagement is moved along rack linear thereby can drive the crocodile head, finishes the stringing operation.When stopping operating wheel shaft,, can prevent the ratchet counter-rotation because the elastic force of spring makes the tight interlock of ratchet and ratchet and a non-return effect.

When the stringing operation, gib head is locked on earth anchor or overhead wire cross-arm dangle, behind tight iron wire of crocodile formula clamp quilt or steel wire, use moving casing wrench rotating axle again, wheel shaft driven gear and ratchet rotate simultaneously, the crocodile head is strained iron wire or steel wire gradually promptly along the tooth bar moving linearly, thereby finishes the stringing operation.

The utility model is compared with existing wire grip, and its advantage is simple in structure, and mounting or dismounting are convenient, and are time saving and energy saving, safe and reliable, iron wire tightly not only, and steel wire tightly.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings:

Fig. 1 is the structural representation of crocodile formula wire grip;

Fig. 2 is the A-A cutaway view of Fig. 1.

As shown in Figure 1, 2, crocodile formula wire grip comprises crocodile head and tooth bar two parts.The crocodile head is made up of casing ［ 5 ］, gear ［ 6 ］, ratchet ［ 7 ］, ratchet ［ 11 ］, wheel shaft ［ 4 ］ and anchor clamps, and anchor clamps are to constitute by carving piece ［ 2 ］, dovetail geosynclinal block ［ 3 ］ and holder line piece ［ 1 ］.Carve piece ［ 2 ］ and insert in the dovetail geosynclinal block ［ 3 ］, be slidingly connected with banking pin.Dovetail geosynclinal block ［ 3 ］ is one with casing ［ 5 ］ weldering, be positioned at an outside of casing, holder line piece ［ 1 ］ is tightened up by screw ［ 12 ］ with casing ［ 5 ］ bottom, have respectively in another outside of casing and casing that ratchet ［ 7 ］ and gear ［ 6 ］ are same to be fixedly mounted on the cuboid wheel shaft ［ 4 ］ that passes casing, the axle tip in the ratchet outside has pad ［ 8 ］ and pin ［ 13 ］ fastening, ratchet ［ 11 ］ is rotatably connected on casing ［ 5 ］ by screw and spring ［ 10 ］, and with closely interlock of ratchet ［ 7 ］, tooth bar ［ 9 ］ passes bottom and gear ［ 6 ］ engagement in the casing, one end of tooth bar is provided with gib head ［ 14 ］, and the other end is spacing screw perforation.

During the stringing operation, gib head ［ 14 ］ is locked on earth anchor or overhead wire cross-arm dangle, again with anchor clamps carve piece ［ 2 ］ and dovetail groove ［ 3 ］ unclamps, behind the tight lead of quilt to be clamped, with wrench rotating axle ［ 4 ］ counter rotation, driven gear ［ 6 ］ and ratchet ［ 7 ］ also counter-clockwise direction rotate simultaneously, and the crocodile head is promptly along tooth bar ［ 9 ］ moving linearly left, so just lead can be strained gradually, be finished the stringing purpose.
