Background technology
Electric Chain Blocks is a kind of lifting gear, is widely used in all trades and professions.When in use, by the electronic calabash of loop chain
Reed is hung on supporting mechanism, is then rotated by the driving mechanism of Electric Chain Blocks band movable sprocket, to drive and sprocket wheel
The chain of engagement moves.The suspension hook of weight can be caught on due to being fixed in the end of chain, can realize the liter to weight
Drop operation.In general, being fixed with the mechanism for collecting chain on Electric Chain Blocks.In actual use, chain is accumulated
It is easy to cause card chain together.On the other hand, the hook spacing of Electric Chain Blocks in the prior art is larger, it is difficult to be applied to pair
Hoisting depth has the place of strict demand.In addition, the Electric Chain Blocks installation difficulty of the prior art is also larger, in installation space
Narrow equal places are difficult with.
Therefore, fairleader is set on Electric Chain Blocks, and fairleader is to make chain at regular intervals fitly around upper volume
Around device, to prevent hoisting-chain confusion, overlapping, card chain, jump chain etc., mechanical breakdown, damage generated so as to cause Electric Chain Blocks
Bad Electric Chain Blocks.But currently, straight mouth guiding dress is usually used in Electric Chain Blocks chain guide in the market
It sets, is easy that chain is made to be partially formed packing phenomenon in chain bag in import, be easy because suspension hook and chain are to the electronic calabash of loop chain
The shock of reed body and the damage for causing parts in body.
Utility model content
The purpose of this utility model is to be directed to the existing above problem, provides a kind of chain guide device of Electric Chain Blocks.
The purpose of this utility model can be realized by following technical proposal：A kind of chain guide device of Electric Chain Blocks,
It includes rack and sprocket wheel, and the sprocket wheel outer rim is equipped with chain nest, which is characterized in that the top of the sprocket wheel is equipped at least one pressure
The lower section of wheel, sprocket wheel is equipped with guide chain cover board；The pinch roller is fixed on the rack, and wheel pressing shaft is parallel with sprocket shaft, and wheel pressing shaft
It is on same benchmark vertical plane with sprocket shaft；The guide chain cover board is vertical with benchmark vertical plane, and guide chain cover board is set there are two upper
Under perforative guide chain groove, guide chain groove mirror symmetry is in benchmark vertical plane both sides；Chain bypasses sprocket wheel, and chain link is in chain nest, institute
The pinch roller stated is pressed on chain, and chain both sides are passed through from guide chain groove, while chain both sides chain link is limited in the chain of sprocket wheel
In nest.
Further, the guide chain cover board is equipped with two sections of extensions extended vertically, and the guide chain groove, which passes through, to be prolonged
Long portion.
Further, the guide chain groove is on the corresponding extended line of vertical tangent line of sprocket wheel, and guide chain separation is equal to
The diameter of sprocket wheel.
Further, the guide chain groove is cross recess.
Compared with prior art, the utility model improves the structure of its guide chain, vertical when limiting drop-down
Direction deviation angle efficiently avoids the drift angle pulling force being subject to when chain link moves in chain nest, the problem of to reduce card chain
It generates.The utility model has more preferably rolling effect and guide effect.
Description of the drawings
The preferred descriptions embodiment of the utility model is explained below with reference to all figures, in the accompanying drawings：
Fig. 1 is the internal component schematic diagram of the present apparatus.
Fig. 2 is that the chain of the present apparatus walks schematic diagram.
In figure, 1, pinch roller；2, sprocket wheel；2a, chain nest；3, guide chain cover board；3a, guide chain groove；3b, extension；4, chain；5, it passes
Dynamic component.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
In Fig. 1, a kind of chain guide device of Electric Chain Blocks is present embodiments provided, it includes that rack (is not shown in figure
Meaning) and transmission component 5.Transmission component 5 is connect with sprocket wheel 2, and drive sprocket 2 rolls.
The top of sprocket wheel 2 is set there are one pinch roller 1, and the lower section of sprocket wheel 2 is equipped with guide chain cover board 3.
Chain volume 4 is on sprocket wheel 2, and pinch roller 1 is pressed in 4 top of chain, and 1 axis of pinch roller is parallel with 2 axis of sprocket wheel, and 1 axis of pinch roller
It is on same benchmark vertical plane with 2 axis of sprocket wheel.1 outer rim of pinch roller is equipped with the groove of a ring shape, convenient for determining in chain 4
The heart.
Guide chain cover board 3 is vertical with benchmark vertical plane, and guide chain cover board 3 is equipped with two sections of extension 3b extended vertically, and prolongs
Long portion 3b is equipped with criss-cross guide chain groove 3a, and the guide chain groove 3a runs through guide chain cover board 3 and extension 3b vertically simultaneously.Guide chain
Slot 3a is on the corresponding extended line of vertical tangent line of sprocket wheel 2, and guide chain groove 3a spacing is equal to the diameter of sprocket wheel 2.The extension
The prolongation effect of 3b can ensure that more piece chain is energy saving while entering in guide chain groove 3a.
Operation principle：Shown in Fig. 2, chain 4 bypasses sprocket wheel 2, and sprocket wheel 2 is equipped with chain nest 2a, and one is corresponded to per shot of a cable section
Chain nest 2a, chain nest 2a push chain 4 to walk about.The pinch roller 1 of top, which is pressed on chain 4, prevents chain 4 from tiltedly partially, also playing the guiding role.
The both sides of chain 4 are passed through from guide chain groove 3a, because chain link is transverse and longitudinal knot, guide chain groove 3a needs that cross structure is arranged.
Reduce card chain to make chain 4 pull down direction and keep vertical, and also to reach minimum friction, therefore by guide chain groove 3a with
The vertical tangent line of sprocket wheel 2 corresponds to.
