Abstract
The utility model relates to a winch self-locking device. The winch self-locking device is characterized by comprising a winch body, wherein the winch body is sequentially and transversely provided with a steel wire winding barrel, a winding driving shaft and a retaining shaft, one side of the steel wire winding barrel and one side of the winding driving shaft are correspondingly provided with a pair of mutually engaged gears, the other side of the winding driving shaft is provided with a handle which is in rigid connection with the winding driving shaft, the winding driving shaft is sheathed with a ratchet, the retaining shaft is correspondingly provided with ratchet teeth acting on the ratchet, and the side surface of the ratchet is provided with a friction plate for increasing the friction force in a fitting way. The winch self-locking device has the advantage that the side surface of the ratchet is provided with the friction plate for increasing the friction force in the fitting way, so the winding and the unwinding of the steel wires can be safely realized in a bidirectional hand rocking way.
Description
Technical field:
The utility model relates to a kind of capstan machine self-locking device for coiling steel wire.
Background technology:
Engineering illuminating lamp is widely used in the illumination at field activity scene, such as carrying on construction work at night and the illumination of the field work of army of municipal administration, highway, bridge, airport, harbour, mine, building etc.Because this part engineering illuminating lamp power is large, irradiation distance is far away, thereby need to be supported by large-scale lamp stand fixingly, and the lifting of large-scale lamp stand will be used coiling steel wire capstan machine,
The capstan machine of present coiling steel wire, all can only the hand coiling steel wire of forward, as wanting reverse hand release steel wire, just must unclamp ratchet, held the release of handle one tooth one tooth by the staff, if staff's hand-power just can't grip the handle of stopping not like this, can cause large-scale lamp stand free fall, cause the accident.
Summary of the invention:
The purpose of this utility model namely is to provide a kind of capstan machine self-locking device, and this capstan machine self-locking device can realize that steel wire is reeled, discharged to Bidirectional hand-operated safely.
The utility model is achieved through the following technical solutions:
The utility model capstan machine self-locking device, it is characterized in that: the capstan body that comprises the capstan machine, steel wire winch spool, coiling axle drive shaft and retaining axle have been horizontally set with successively on the described capstan body, one side correspondence of described steel wire winch spool and coiling axle drive shaft is provided with intermeshing a pair of gear, the opposite side of described coiling axle drive shaft is provided with and the rigidly connected handle of the axle drive shaft of reeling, also be arranged with ratchet on the described coiling axle drive shaft, the corresponding ratchet that is provided with the effect ratchet on the described retaining axle, described ratchet side is fitted with the friction lining that increases friction force.
Being provided with between above-mentioned friction lining side and the capstan body wall face can be with the paster of coiling drive shaft turns.
Be equipped with friction lining and paster on the two sides of above-mentioned ratchet.
Above-mentioned retaining axle is provided with the coiling preloading spring, so that be located at the ratchet of retaining shaft end ratchet is had precompressed compression.
Above-mentioned steel wire winch spool is provided with the protruding nail of hook steel wire.
The utility model capstan machine self-locking device is fitted with the friction lining that increases friction force by the ratchet side, thereby can realize that steel wire is reeled, discharged to Bidirectional hand-operated safely.
Description of drawings:
Fig. 1 is organigram of the present utility model;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 is the B-B section-drawing of Fig. 1.
The specific embodiment:
With reference to figure 1, the utility model capstan machine self-locking device, the capstan body 1 that comprises the capstan machine, steel wire winch spool 2, coiling axle drive shaft 3 and retaining axle 4 have been horizontally set with successively on the capstan body 1, one side correspondence of steel wire winch spool 2 and coiling axle drive shaft 3 is provided with intermeshing a pair of gear 7, the opposite side of coiling axle drive shaft is provided with and the axle drive shaft 3 rigidly connected handles 5 of reeling, also be arranged with ratchet 6 on the coiling axle drive shaft 3, the corresponding ratchet 8 that is provided with effect ratchet 6 on the retaining axle 4, ratchet 6 sides are fitted with the friction lining 9 that increases friction force.
In order to allow Bidirectional hand-operated reel, to discharge the steel wire better effects if, being provided with between above-mentioned friction lining 9 sides and the capstan body wall face 10 can be with the paster 11 of coiling drive shaft turns.During coiling steel wire work, paster 11 is with coiling axle drive shaft, ratchet 6 coaxial rotation; When discharging steel wire work, paster 11 is with the coiling axle drive shaft, and ratchet 6 is not with the coiling drive shaft turns, but ratchet is fixed relatively.If it is also passable certainly paster 11 not to be set, friction lining directly rubs with capstan body wall face 10 and has too same function.
In order to allow Bidirectional hand-operated reel, to discharge the steel wire better effects if, on the two sides of above-mentioned ratchet, also can be equipped with friction lining and paster.
In order to guarantee the stability of retaining axle work, above-mentioned retaining axle 4 is provided with coiling preloading spring 12, so that be located at the ratchet of retaining shaft end ratchet is had precompressed compression.
For instant rolled around, above-mentioned steel wire winch spool is provided with the protruding nail 13 of hook steel wire.
The principle of work of the utility model capstan machine self-locking device: when wanting coiling steel wire to rise lamp stand, cw crank handle (the right apparent direction visual angle of Fig. 1), at this moment, ratchet does not have the clamping stagnation effect to ratchet, handle and coiling axle drive shaft are for being rigidly connected, gear engagement on the coiling axle drive shaft drives the steel wire winch spool and rotates, and steel wire coil is around accommodating; When discharging steel wire decline lamp stand constantly, conter clockwise crank handle (the right apparent direction visual angle of Fig. 1), at this moment, ratchet has the clamping stagnation effect to ratchet, the relative ratchet of ratchet is motionless, but because the ratchet side is provided with friction lining, thereby has certain friction drag (size of this resistance can be regulated by the locking degree of screw) when allowing handle rotate counterclockwise, operating personal just needn't be broken ratchet into two with one's hands by a hand like this, a hand is held handle again, can realize safely reverse hand release steel wire, thereby avoid steel wire high speed pay-out under large-scale lamp stand Action of Gravity Field, cause the accident.
