Abstract
The invention discloses a winch. The winch comprises a power mechanism, a transmission mechanism, a coiling block and a rope, wherein the power mechanism is used for driving the transmission mechanism to drive the coiling block and the rope to rotate. The winch further comprises a braking mechanism which consists of a ratchet and a pawl; the ratchet is connected with the coiling block; the pawl is connected to the transmission mechanism. According to the technical scheme, the winch has the advantage that serious potential risk can be effectively prevented while the electricity is cut off to cause power lacking.
Description
Technical field
The present invention relates to hoist engine field is used in lifting, especially relate to a kind of hoist engine.
Background technology
Hoist engine, with the small-sized crane gear of reel lay winding wire ropes or chain lifting or traction, also known as winch.
Hoist engine can with vertical-lift, horizontally or diagonally drag and draw weight.Can be used alone, also can make lifting, build the road and mine hoisting etc.
Building block in machinery, because simple to operate, wiring amount is big, dislocation is convenient and extensively apply.Mainly apply to building, water conservancy work
The material of journey, forestry, mine, harbour etc. lifts or puts down and drags.
Hoist engine in existing construction site adopts driven by power mostly, is compared to manual mode, being capable of lifting weight
Larger object.But, after the hoist engine using driven by power is in unexpected power-off, if the weight of lifting is in the air,
Reel will turn round, and leads to object to drop, and has very big potential safety hazard in the personnel of terrestrial operation, and
And when motor output power cannot lifting heavy when, or when motor breaks down, above-mentioned safety problem equally occurs.
Content of the invention
A kind of in view of defect that above-mentioned prior art exists, the purpose of the present invention is to propose to hoist engine.
As the first embodiment, the invention provides a kind of hoist engine, including actuating unit, transmission mechanism, reel
And rope, described actuating unit drives described transmission mechanism to drive described reel and described rope to rotate, and described hoist engine also wraps
Include arrestment mechanism, described arrestment mechanism includes ratchet and pawl, described ratchet is connected with described reel, described ratchet and described biography
Motivation structure connects.
On the basis of the first embodiment, as second embodiment, described actuating unit and described driver
It is provided with reductor between structure.
On the basis of the first embodiment, as the third embodiment, described ratchet and described ratchet are at least
A pair.
On the basis of the third embodiment, as the 4th kind of embodiment, described ratchet and described ratchet are right for two,
And described two pairs of ratchets are stepped in synchronization with ratchet.
A kind of hoist engine provided by the present invention, by arranging ratchet and ratchet, under the driving of ratchet, ratchet does unidirectional
Thus driving spool turns to drive rope lifting heavy, after the power of lifting suddenly disappears, ratchet equally can be by spine for motion
Wheel blocks, and will not drop, thus the operating personnel on ground for the protection.
Brief description
Fig. 1 is the structural representation of hoist engine provided in an embodiment of the present invention.
Specific embodiment
In order that present invention solves the technical problem that, the beneficial effect of the technical scheme that adopts and generation more clear bright
In vain, below in conjunction with drawings and Examples, the present invention is described in further detail.It should be appreciated that described herein be embodied as
Example is used only for explaining the present invention, is not intended to limit the present invention.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, it can be directly another
On one element or may be simultaneously present centering elements." it is connected to " another element when an element is referred to as, it can
To be directly to another element or to may be simultaneously present centering elements.
Specifically, as shown in figure 1, a kind of hoist engine of the present embodiment offer, including actuating unit 1, transmission mechanism 2, roll up
Cylinder 3 and rope 4, actuating unit 1 drive transmission device 2 band movable reel 3 and rope 4 rotate, and hoist engine also includes arrestment mechanism 5,
Arrestment mechanism 5 includes ratchet 501 and ratchet 502, and ratchet 501 is connected with reel 3, and ratchet 502 is connected with transmission mechanism 2.
Wherein, ratchet 501, under the drive of ratchet 502, can do one-way movement, drives rope 4 lifting heavy, when unexpected
When running out of steam, ratchet 501 can be blocked by ratchet 502, so that reel 3 will not be turned round, be effectively protected operating personnel.
Specifically, it is provided with reductor 6 between actuating unit 1 and transmission mechanism 2.The speed of actuating unit 1 is subtracted by reductor 6
Speed to the entirety being suitable for hoist engine.
Specifically, ratchet 501 and ratchet 502 are at least one pair of.Can for being distributed in any side of reel 3 for a pair,
Can be right for two, it is distributed in the both sides of reel 3 respectively.
Specifically, ratchet 501 and ratchet 502 are right for two, and two pairs of ratchets 501 are stepped in synchronization with ratchet 502.Synchronous
Motion, on the one hand can lift heavier object, on the other hand, when electric power suddenly disappears, can be safer play engaging
Effect.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Any modification, equivalent or improvement of being made within principle etc., should be included within the scope of the present invention.
