Fig. 1 is the stereoscopic schematic diagram of mechanical activation device of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the present invention provides a kind of mechanical activation device, with small in size, light-weight and can effectively limit
The advantages of speed, braking.The mechanical activation device includes: bracket 1, rope wheel component 2, hypophysis component 3, stops component 4, pawl group
Part 5.
The bracket 1 is used for that the installation for other assemblies is fixed to provide basis, the bracket 1 include: bottom plate 11 and oneself
The side 12 that the holding that 11 both sides of the edge of bottom plate are stretched out is oppositely arranged.
The rope wheel component 2 includes: rope sheave ontology 21, the side wall surface edge for being set to the rope sheave ontology 21
Double wedge 22.
The rope sheave ontology 21 can be pivoted movement by shaft 211 of center axis, and circumferential surface has auxiliary
Help the groove that wirerope bypasses.Under the action of frictional force, the rope sheave ontology 21 can generate drawing to around wirerope on it
Power.The movement of the rope sheave ontology 21 for convenience, the centers of 21 two side walls of rope sheave ontology by shaft 211 with
The side 12 of two sides is pivotally connected, correspondingly, offering the through-hole 121 passed through for the shaft 211 on the side 12 of two sides.It is excellent
Selection of land, the through-hole 121 are the card slot knot that can be interference fitted with shaft 211 for being opened in the top edge of the side 12
Structure.Meanwhile the rolling for assisting 21 shaft 211 of rope sheave ontology is additionally provided between the shaft 211 and the rope sheave ontology 21
Pearl bearing.
The double wedge 22 with the pawl assembly 5 for being meshed.Wherein, the double wedge 22 is multiple, any double wedge 22
A meshing point is formed, multiple double wedges 22 are along the circumferential equidistantly distributed of the rope sheave ontology 21.Preferably, between adjacent tooth 22
The angle value of the corresponding central angle of circular arc is at most 20 °.So set, be conducive to rope sheave ontology 21 can rapidly with the spine
Claw assembly 5 forms interaction relation.
The hypophysis component 3 is for triggering the stops component 4, to realize pawl assembly 5 and 21 upper raised teeth of rope sheave ontology
Engagement between 22.Specifically, the hypophysis component 3 is slidably mounted on the rope sheave ontology 21 comprising: hypophysis 31,
It is set on the hypophysis 31 and makes bar 32.The waist hole for radially extending setting, the hypophysis are provided on the rope sheave ontology 21
31 slide setting along the waist hole by bearing thereon, and carry out centrifugal movement with the pivot of the rope sheave ontology 21.
The bar 32 of beating is set on the axial lateral surface 12 of the hypophysis 31.To be transported with the centrifugation of the hypophysis 31
Dynamic, the moving radius of the hypophysis 31 is gradually increased, and when its dozen of bars 32 reach the position of stops component 4, can be touched with it
Hit realization triggering.
In one embodiment, the hypophysis component 3 is two, and two hypophysis components 3 are symmetrically distributed in institute
It states on rope sheave ontology 21.To which when carrying out centrifugal movement, the radial distance of the hypophysis 31 in two hypophysis components 3 gradually increases
Greatly, it is arranged such and is conducive to fast implement mechanical triggering.
The stops component 4 is used for the braking of the pawl assembly 5, is installed on the bracket 1, and is distributed in described
The marginal position of rope sheave ontology 21, the stops component 4 include: stops 41, are set on the end face of described 41 one end of stops
Screw 42.The screw 42 is vertically bolted in the screw hole of the end face, and the stops 41 is pivotally mounted to the bracket 1
Side 12 on, the end face of 41 other end of stops is the arcwall face of a recess, to be adapted with the pawl assembly 5.
When the stops 41 is located at initial position, end face is pressed on the pawl assembly 5 so that pawl assembly 5 with
22 phase of double wedge separation on rope sheave ontology 21, avoids the two from engaging.When rope sheave ontology 21 is with normal rotational speed, hang down
Body 31 is located at initial position.When the speed that rope sheave ontology 21 rotates is getting faster, hypophysis 31 is in the centrifugation masterpiece being gradually increased
Under, centrifugal movement is carried out along the waist hole.When the moving radius of hypophysis 31 reaches the screw 42 and the rope sheave ontology 21
The distance between the center of circle when, the bar 32 of beating collides with the screw 42, and then it is pivoted to trigger stops 41, in turn
The active force applied to pawl assembly 5 is released, pawl assembly 5 is meshed to the rope sheave ontology 21.
In conclusion hypophysis moves in a straight line in speed limit operation process in mechanical activation device of the invention；Hypophysis touching
When sending out machine screw, there is no angles for the suprapituitary screw beaten on bar and stops.
