Abstract
The utility model discloses a unidirectional brake pulley device. The unidirectional brake pulley device comprises a hook, a rope, a front hanging plate, a rear hanging plate, a pulley, a unidirectional gear and a main shaft, one end of the front hanging plate and one end of the rear hanging plate are both connected with the hook, the other end of the front hanging plate, the other end of the rear hanging plate, and the unidirectional gear are all fixed to the main shaft, the unidirectional gear is positioned between the front hanging plate and the rear hanging plate, the unidirectional gear is sleeved by the pulley, the pulley and the unidirectional gear form a ratchet mechanism, the periphery of the pulley is provided with an annular groove, and the rope winds around the annular groove of the pulley. According to the unidirectional brake pulley device, the rolling of the pulley during lifting, and the reverse brake of the unidirectional pulley and the sliding friction brake of a pulley body during brake are fully employed, the labor intensity of work personnel is effectively reduced, the work efficiency is improved, and safety measures of on-site construction are improved.
Description
Technical field
The utility model belongs to power construction field, relates to a kind of one-way brake tackle arrangement.
Background technology
In electric force pole tower maintenance and work progress, in existing pulley gear, lifting and the main dependence of braking manpower are realized by the rotation of pulley, after weight is liftoff, operating personnel need pay the power that is greater than weight weight it is promoted, when especially the long-time suspention of weight is aerial, because manpower is limited, workmen's braking is required great effort very much, also very easily cause personnel tired, security risk is very big, easily causes personal injury accident to occur, and is badly in need of a kind of energy and saves physical pulley gear.
Utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of one-way brake tackle arrangement is provided, the easily braking of this device, safety, reliable.
For achieving the above object, one-way brake tackle arrangement described in the utility model comprises hook, rope, front link plate, rear link plate, pulley, ratchet and main shaft, one end of front link plate and one end of rear link plate are all connected with hook, the other end of front link plate, the other end of rear link plate and ratchet are all fixed on main shaft, ratchet is between front link plate and rear link plate, pulley sleeve is connected on ratchet, pulley and ratchet have formed a ratchet mechanism, the periphery of pulley is provided with annular groove, and rope is walked around annular groove on described pulley.
Described front link plate and rear link plate are all fixed on main shaft by snap ring.
Described front link plate and rear link plate are connected with hook by force-bearing pin.
The utlity model has following beneficial effect:
One-way brake tackle arrangement described in the utility model comprises hook, pulley, ratchet and main shaft, when work, rope is walked around pulley, when the long-time suspention of weight is aerial, plugging, pulley groove by pulley are realized braking to the rope generation grip of crimp and the sliding friction of pulley and rope, in weight lifting process, can utilize the braking action of pulley to have a rest, need not continue firmly, during braking, only need less power just can realize braking, greatly reduce workmen's labour intensity and the risk of accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is end view of the present utility model.
Wherein, 1 for hook, 2 be that front link plate, 3 is rear link plate for main shaft, 8 for snap ring, 7 for ratchet, 6 for pulley, 5 for force-bearing pin, 4.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1 and Fig. 2, one-way brake tackle arrangement described in the utility model comprises hook 1, rope, front link plate 2, rear link plate 8, pulley 4, ratchet 5 and main shaft 7, one end of one end of front link plate 2 and rear link plate 8 is all connected with hook 1, the other end of front link plate 2, the other end of rear link plate 8 and ratchet 5 are all fixed on main shaft 7, ratchet 5 is between front link plate 2 and rear link plate 8, pulley 4 is socketed on ratchet 5, pulley 4 has formed a ratchet mechanism with ratchet 5, the periphery of pulley 4 is provided with annular groove, rope is walked around annular groove on described pulley 4, front link plate 2 and rear link plate 8 are all fixed on main shaft 7 by snap ring 6, described front link plate 2 and rear link plate 8 are connected with hook 1 by force-bearing pin 3, pulley 4 is provided with annular groove, rope is walked around annular groove on described pulley 4.
Specific works process of the present utility model is:
When work, staff is by one end of being fixed on rope of weight, the then other end of hand-held rope, when the long-time suspention of weight is aerial, by plugging and the pulley 4 of pulley 4, realize braking with the sliding friction of rope, the utility model cost of manufacture is cheap, in using at the scene, can effectively reduce labour intensity, reduce human cost, accelerate job schedule, shorten working hours, for Research Work of Power Transmission Line, to shorten working hours, the economic benefit that power transmission produces is in advance very remarkable.Owing to having reduced labour intensity, reduced the personal injury accident that personnel's fatigue may cause in addition, economic results in society are obvious equally.
Above content can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the utility model and determine scope of patent protection by submitted to claims.
