Description
Technical field
The utility model belongs to mechanical field, relate to a kind of for pulling the mechanical structure of electric wire, a kind of wire drawing system particularly.
Background technology
High-tension apparatus in use, generally all can regularly overhaul, and to solve some potential safety hazards, avoids equipment, electric wire because of permanent use generation loss; When carrying out high-tension electricity maintenance, although high-tension apparatus meeting power-off, but may there is unexpected incoming call, fall power transmission or faradic situation, in order to prevent that staff from getting an electric shock, guarantee trouble free service, generally all the ground wire of a connection high-tension apparatus can be set, the end, ground, is squeezed in ground wire lower end, in case the harm of leak-stopping electricity to staff;
After staff has overhauled, need ground wire to reclaim, because ground wire is driven underground, when extracting, need many people jointly to exert all one's strength, when manpower is difficult to extract sometimes, also need to use large-scale instrument to pull out line, not only waste time and energy, and cost is high, expends time in.
Utility model content
For overcoming prior art, manually pull out the technological deficiency that line exists, the utility model discloses a kind of wire drawing system.
Wire drawing system described in the utility model, comprises cable connecting part and the force section being connected with cable connecting part, and described force section comprises installing rack, be arranged on the cable that gear train on installing rack and two ends are fixedly connected on respectively installing rack and cable connecting part; Described gear train comprise master gear, with master gear engagement from gear, with from the coaxial fixing ratchet of gear, the main shaft of described master gear, from gear and the coaxial installation of ratchet, from rotating shaft, be all fixedly connected on installing rack, described from rotating shaft end be fixedly connected with from the vertical handle of rotating shaft, described master gear diameter with from gear diameter than for 1.5-4:1.
Preferably, described master gear diameter is 2:1 with comparing from gear diameter.
Preferably, described cable connecting part is hook.
Further, described hook stiff end is provided with locking sheet.
Preferably, fixing movable rotation-shaft also on described installing rack, is fixed with cable guide cover on described movable rotation-shaft.
Preferably, described installing rack top also has draw ring.
Adopt wire drawing system described in the utility model, adopt gear train to alleviate the required pulling force of bracing wire, operating personnel can complete alone and pull out line operation, the mode of operation of gear train and handle make to pull out line is stressed can even variation, effectively avoided pulling out the danger that line comes off suddenly and may cause.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment structural representation of the present utility model;
In figure, Reference numeral name is called: 1-installing rack 2-cable 3-master gear 4-is from gear 5-ratchet 6-handle 7-cable guide cover 8-hook 9-locking sheet.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Wire drawing system described in the utility model, comprises cable connecting part and the force section being connected with cable connecting part, and described force section comprises installing rack 1, be arranged on the cable 2 that gear train on installing rack and two ends are fixedly connected on respectively installing rack and cable connecting part; Described gear train comprise master gear 3, with master gear engagement from gear 4, with from the coaxial fixing ratchet 5 of gear, the main shaft of described master gear, from gear and the coaxial installation of ratchet, from rotating shaft, be all fixedly connected on installing rack, described from rotating shaft end be fixedly connected with from the vertical handle 6 of rotating shaft, described master gear diameter with from gear diameter than for 1.5-4:1.
While not using at ordinary times, can be by the guy winding of wire drawing system on the main shaft of master gear, convenient storage is placed.While carrying out bracing wire operation, cable connecting part and the cable that will pull are fixed together, operating personnel grip installing rack on the other hand, turning handle, drives ratchet and rotates from gear on the other hand, owing to meshing from gear and master gear, master gear is started rotation from gear driven, the cable being wound around on main shaft is tightened up gradually or is loosened, and the cable stress being pulled is along with the tight of cable increases gradually, and final realization pulled out line operation or pull.
Adopt the utility model, operating personnel get final product complete operation, the design of handle and the engagement of master and slave gear greatly reduces operating personnel's labour intensity, make cable stress increase in proper order and not mutated simultaneously, avoid cable to extract suddenly or stressed situation generation of snapping, improved processing safety.Master gear and meshing from gear gear, tooth pitch is roughly the same, by master gear and from gear diameter ratio setting the proper ratio at 1.5-4:1, the excessive master gear of ratio size increases, and weight increase, the each application of force of operating personnel also will increase, the little number of turns that increases operating personnel's rotary handles of ratio, extend the operating time, the diameter proportion that is preferably arranged on 2:1 is comparatively suitable.
The function of cable connecting part is the cable that interlock will pull, can be hook, wire clamp, draw ring etc., in the utility model, preferably adopt hook 8, the hook degree of reliability is better than wire clamp, facilitate hooking cable and no matter cable has or not free end simultaneously, for preventing that being pulled cable comes off from linking up with 8, can locking sheet 9 be set at hook stiff end, hook catches on after cable, and locking sheet end button is extremely being linked up with on free end.
Another is preferred embodiment: fixing movable rotation-shaft also on described installing rack, is fixed with cable guide cover 7 on described movable rotation-shaft.Cable is passed from cable guide cover, during use, with the rotation of movable rotation-shaft, by cable guide cover, cable direction is positioned, avoid cable significantly to swing and cause discontinuity.
Preferably, described installing rack top also has draw ring, and convenient the utility model being fixed in the engineering machinery such as trailer is applied to the occasion that manpower can not complete operation.
Adopt wire drawing system described in the utility model, adopt gear train to alleviate the required pulling force of bracing wire, operating personnel can complete alone and pull out line operation, the mode of operation of gear train and handle make to pull out line is stressed can even variation, effectively avoided pulling out the danger that line comes off suddenly and may cause.
Previously described is each preferred embodiment of the present utility model, preferred implementation in each preferred embodiment is if not obviously contradictory or take a certain preferred implementation as prerequisite, each preferred implementation arbitrarily stack combinations is used, design parameter in described embodiment and embodiment is only the utility model proof procedure for clear statement utility model people, not in order to limit scope of patent protection of the present utility model, scope of patent protection of the present utility model is still as the criterion with its claims, the equivalent structure that every utilization specification of the present utility model and accompanying drawing content are done changes, in like manner all should be included in protection range of the present utility model.
