Abstract
The utility model discloses a kind of brake used for electric hoist, including ratchet and pawl, the ratchet includes the first rotation axis, the pawl includes the second rotation axis, second rotation axis is located at the top of first rotation axis, second rotation axis is equipped with torque spring, described torque spring one end is fixed in second rotation axis, the torque spring other end is contacted with the detent face, on the pawl tension spring is equipped with away from described second rotation axis one end, the tension spring and electric block are affixed, moving block is additionally provided with the ratchet, the moving block and the ratchet are not coaxial.Due to a kind of brake used for electric hoist using the utility model, there is the advantages that simple in structure, firm and durable, braking time is short.
Description
Technical field
It the utility model is related to a kind of brake used for electric hoist.
Background technology
Electric block is for a kind of lifting equipment to operations such as material lifting, transport, handling and installations, existing electricity
Dynamic cucurbit brake apparatus is made of motor braking mechanism and reductor braking mechanism, after its long-time use, braking ability can under
Drop, can not have when the parts damages such as bearing in reduction gears, gear, tooth shaft or motor braking mechanism, reductor braking mechanism occur
During effect braking, the weight of lifting can accelerate to fall under the effect of gravity, cause very serious loss.People need one kind to work as main system
During dynamic failure of apparatus, the emergency braking apparatus that can enable automatically.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of brake used for electric hoist, have
It is simple in structure, braking time is short, it is safe the advantages that.
The technical problem that the utility model is solved is realized using following technical scheme：
A kind of brake used for electric hoist, including ratchet and pawl, the ratchet include the first rotation axis, the pawl bag
The second rotation axis is included, second rotation axis is located at the top of first rotation axis, and second rotation axis is equipped with torsion
Spring, described torque spring one end are fixed in second rotation axis, the torque spring other end and the detent face
Contacting, tension spring is equipped with away from described second rotation axis one end on the pawl, the tension spring and electric block are affixed,
Moving block is additionally provided with the ratchet, the moving block and the ratchet are not coaxial.
Further, the ratchet includes two around the equally distributed hook tooth of axis.
Further, the tension spring is equipped with L-shaped fixinig plate with pawl junction, and the tension spring is overlapped on L-shaped
On fixinig plate.
The utility model uses beneficial effect possessed by above technical scheme：It is simple in structure, braking time is short, safety.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described.
Fig. 1 is a kind of brake used for electric hoist structure diagram according to the utility model embodiment.
In figure：
1st, ratchet；2nd, moving block；3rd, pawl；4th, torque spring；5th, tension spring；6th, the first rotation axis；7th, second rotate
Axis.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of brake used for electric hoist described in the utility model embodiment, including ratchet 1 and pawl
3, the ratchet 1 includes the first rotation axis 6, and the ratchet 1 is equipped with two around the equally distributed hook tooth of axis, the pawl 3
Including the second rotation axis 7, second rotation axis 7 is located at the top of first rotation axis 6, is set in second rotation axis 7
There is torque spring 4, described 4 one end of torque spring is fixed in second rotation axis 7,4 other end of torque spring and institute
The contact of 3 surface of pawl is stated, remote described second rotation axis, 7 one end is fixed with L-shaped fixinig plate on the pawl 3, and the L-shaped is fixed
On piece is overlapped with tension spring 5, and 5 other end of tension spring and electric block are affixed, and moving block is additionally provided with the ratchet 1
2, the moving block 2 and the ratchet 1 are not coaxial.
When weight stall is fallen, ratchet 1 accelerates to rotate along clockwise, and moving block 2 under the action of the centrifugal force, hits pawl
3, pawl 3 and tension spring 5 are separated, and then ratchet contact of the pawl 3 under the action of torque spring 4 and on ratchet 1, and it is right
Ratchet 1 produces brake drag.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
