Summary of the invention
To resolve the above problem, the present invention provides two connecting rod continuous constraint devices of chain rope, including middle part directive wheel
Interval restraint device, it is characterised in that: restraint device uses two connecting rod guide plate continuous constraint devices;Two connecting rod guide plates are by two
Shape, the identical stamping steel plate of size and its locking shaft composition being connected, structure it is simple, it can be achieved that it is continuous about
Beam, effect are more preferable.
The sum of two connecting rod guide plate thickness is equal with the constraint groove width of chain rope sheave, takes two and by a guide plate edge therein
The aperture axis of guide plate width inverts 180 °, is nested with another guide plate along guide plate aperture, with locking shaft locking, constitutes two
One basic constraint element of connecting rod continuous constraint device, two guide plates can be rotated around locking shaft, and other two of two guide plates
Slightly larger hole can be sleeved on the chain rope sling pipe end of two adjacent worn lockings of chain tooth shaft, turn two guide plates can around chain rope sleeve
It is dynamic.
Because two board-like connecting rods of set can with respect to three connecting shaft Small-angle Rotations, rigid straight continuity cage plate is with respect to shaft
The other side width dimensions in hole are relatively large, and to constrain working side, chain rope enters when engaging with chain rope sheave, rigid cage plate nesting chain
In the restraint slot of rope sheave, defines that chain rope is changed along the displacement of sprocket wheel axial direction, a biggish obtuse angle three is constituted between three axle center
It is angular, the operating distance between two big axis cores be it is variable, in straight line workspace, length is maximum, and it is long to be equal to standard link
Degree, with the complete overmask of sprocket wheel, length be sprocket surface arc length be equal to standard link length when, two corresponding sprocket between centers
Chord length, distance is most short, when chain rope enters and with chain rope sheave engage or is detached from the camber line that chain rope sheave engages and add linear section, grows
Degree is located at above-mentioned maximum standard link away between, two axis chord length distance of minimum;
Specifically, between linearity sector, each standard link, two board-like connecting rods of set are with adjacent two chains tooth shaft, standard link
The isosceles triangle at obtuse angle, obtuse angle be in maximum rating between three axle center of length and the board-like tie rod holes axis of set, when chain rope into
Chain rope sheave starts to leave the beginning when engagement because of adjacent two chain distance between axles and become smaller, and covers board-like connecting rod while being embedded in grooved rail, triangle
The obtuse angle of shape starts to become smaller, and because opposite three hinge axis of two sets of board-like connecting rods can be rotated, the interior angle variation of obtuse triangle can be suitable
Benefit carries out, and ensures that load power sprocket will not cover board-like connecting rod and be completely embedded into slot along its axial displacement when entering at a fully engaged
Rail, effect of contraction is most strong, and triangle obtuse angle, which becomes smaller, to be reached the limit values, and distance length reaches most short between adjacent two chains tooth shaft chord length,
When chain rope enter engage or be disengaged from chain rope sheave when, two chain distance between axles are left the beginning and are become smaller or larger, completely into straight
When line area, two chain axle bases change back to standard link length, and this two connecting rods restraint device is continuity constraint, constraint effect
Fruit is good

It include: chain link sets of holes 1, two link assemblies 2, connecting rod aperture 3, chain tooth shaft 4, sprocket set roller 5, chain in above-mentioned 4 figures
Save casing 6, sprocket shaft locking device 7, load axis 8, zip length adjusting block 9, connecting rod hinge shaft locking device 10, chain rope sheave 11, sprocket wheel
Restraint slot 12.
Lead to below and illustrate to constrain working principle and application after embodiment:
Specifically manufacture implementation method:
Parts, assembling and the continuous constraint principle of two connecting rod continuous constraint devices, are shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4.
A kind of mold is filled with press machine and goes out multiple link assemblies 2, and the thickness of link assembly 2 is equal to sprocket wheel constraint groove width
Half takes two two link assemblies 2, will wherein 180 ° of overturning, an alignment hole mandrel coincide by figure one, by two connecting rod cage plates
It is connected and is locked with connecting rod hinge shaft locking device 10, the referred to as two basic constraint elements of connecting rod chain link, abbreviation chain link restraint assembly, it can
It is multiple by encapsulation on adjacent 6 end outer arc wall of chain link casing, together by chain tooth shaft 4,7 combination locking of sprocket shaft locking device
Chain link restraint assembly is continuously sleeved in continuous chain tooth shaft, just constitutes two connecting rod continuous constraint devices;
Two connecting rod continuous constraint devices are run together with chain rope, and chain rope is nibbled since entering with chain rope sheave 11 straight line workspace
When closing or being detached from engaging, the cage plate of two connecting rod restraint devices starts in the sprocket wheel restraint slot 12 of nested chain rope sheave 11, or is detached from
The sprocket wheel restraint slot 12 of chain rope sheave 11, the sprocket wheel restraint slot 12 of chain link restraint assembly nesting chain rope sheave 11, defines chain rope along chain
Wheel shaft to displacement change, between linearity sector, each standard link, with chain link restraint assembly constitute an obtuse triangle,
Straight line workspace, continuous constraint device can play the role of absorbing surely with determine chain rope operation, when its enter and chain rope sheave 11 start
When engagement, two chain distance between axles leave the beginning and become smaller, and because chain link restraint assembly inner sleeve board width is worth larger, cage plate is embedded in sprocket wheel about
Beam slot 12 can ensure that load power sprocket will not be along its axial displacement, as the obtuse angle of original obtuse triangle starts to become
Small, because opposite three hinge axis of two sets of board-like connecting rods can be rotated, the interior angle variation of obtuse triangle can be gone on smoothly, when enter with
When chain rope sheave 11 is at a fully engaged, covers and be completely embedded into grooved rail on the inside of board-like connecting rod, effect of contraction is most strong, and triangle obtuse angle, which becomes smaller, to be reached
Minimum, the chord length of two chain between centers reach most short, when chain rope enters and engages or be disengaged from chain rope sheave, two chain between centers
Distance starts to become smaller or increase, and when completely into linearity sector, two chain axle bases change back to standard link length.
Two connecting rod continuous constraint devices of chain rope, constraint is more stable, works more reliable, noise is smaller, is the best of chain rope
Restraint device, the production of two connecting rods is simple, and task performance more secure and reliable is the optimal selection of chain rope.
