Cheng Zhong, lifting driving-chain drops rapidly if there is chain rupture situation, then ride plate, it is possible to cause equipment and car to damage.
Utility model content
The purpose of this utility model is to provide a kind of chain breakage protection device, after driving-chain chain rupture is lifted, can embrace rapidly
Dead driven sprocket, can avoid ride plate from dropping, so as to realize chain rupture defencive function.
The technical solution of the utility model is as follows：
A kind of chain breakage protection device, includes motor, power transmission shaft, the drive sprocket on motor output shaft, installs
The endless drive chain and chain rupture protection mechanism of driven sprocket, connection drive sprocket and driven sprocket on power transmission shaft, it is special
Levy and be：Described chain rupture protection mechanism includes support, and the both sides of the support have been respectively fixedly connected with left and right slideway, branch
It is rotatablely equipped with left and right ratchet on frame respectively between described left and right slideway, being respectively equipped with described left and right slideway can
Along the left and right tubular frame horizontally slipped inside it, left and right cunning is respectively fixedly connected with the inside of the left and right tubular frame outer end
Bullet is connected between block, described left-hand cylinder shape frame and left pawl, left pawl and right ratchet and right ratchet and right tubular frame
Spring；The both sides of the endless drive chain are each passed through described left and right tubular frame, and between the left and right sliding block respectively
For rolling friction coordinates.
Described chain breakage protection device, it is characterised in that：Described left and right slideway is obliquely set.
Described chain breakage protection device, it is characterised in that：It is fixedly connected between the left and right ratchet on described support
Limited location block.
Described chain breakage protection device, it is characterised in that：Described left and right sliding block is respectively fixedly connected with by fixing screws
In the inner side of the left and right tubular frame outer end.
The beneficial effects of the utility model：
The utility model simple structure, after driving-chain chain rupture is lifted, being capable of locking driven sprocket rapidly, it is to avoid ride
Plate drops, it is achieved thereby that chain rupture defencive function.

Specific embodiment
Referring to accompanying drawing, a kind of chain breakage protection device includes motor 1, power transmission shaft 11, on the output shaft of motor 1
The endless drive chain 9 of drive sprocket 3, the driven sprocket 6 on power transmission shaft 11, connection drive sprocket 3 and driven sprocket 6
With chain rupture protection mechanism, chain rupture protection mechanism includes support 2, and the both sides of support 2 have been respectively fixedly connected with left and right slideway 7, branch
It is rotatablely equipped with left and right ratchet 5 on frame 2 respectively between left and right slideway 7, interior being respectively equipped with of left and right slideway 7 can be along inside it
The left and right tubular frame 4 for horizontally slipping, left and right sliding block 10, left-hand cylinder shape have been respectively fixedly connected with the inside of the left and right outer end of tubular frame 4
Spring 8 is connected between frame and left pawl, left pawl and right ratchet and right ratchet and right tubular frame；Endless drive chain
9 both sides are each passed through left and right tubular frame 4, and rolling friction cooperation is respectively between left and right sliding block 10.
In the utility model, left and right slideway 7 is obliquely set.
Limited block 12 is fixedly connected with support 2 between left and right ratchet 5.
Left and right sliding block 10 is respectively fixedly connected with the inner side of the left and right outer end of tubular frame 4 by fixing screws 13.
The utility model is further described below in conjunction with accompanying drawing：
The both sides of endless drive chain 9 are each passed through left and right tubular frame 4, are formed respectively between left and right sliding block 10 and rolled
Friction.Now, endless drive chain 9 is in tensioning state so that left-hand cylinder shape frame and left pawl and right ratchet and right tubular frame
Between spring be in impaction state, and spring between left and right ratchet 5 is in extended state, and left and right ratchet 5 is in spring 8
Difference left and right deviation under effect.
After generation chain rupture, because endless drive chain 9 is in relaxed state, left and right tubular frame 4 loses tensile force and difference
To contract, now left and right ratchet 5 shrinks respectively inwards in the presence of spring 8, until under the position-limiting action in limited block 12
Make left and right ratchet 5 no longer to contract, the lower end of left and right ratchet 5 is respectively protruding between the gear teeth of driven sprocket 6, so that will
The driven sprocket 6 of rotation is blocked, and it is stopped operating, and causes ride plate to continue tenesmus, so as to realize defencive function.
No matter motor 1 is in forward or reverse, the equal energy of driven sprocket 6 that 5 pairs, left and right ratchet is rotated clockwise or counterclockwise
Realize protection.
