Technical field
The utility model relates to the safe falling proof device of a kind of mechanical type for mechanical three-dimensional parking device and crane gear.
Background technology
In mechanical three-dimensional parking device, safe falling proof device is a kind of important protective device, and the reliability of this device is determining the safety of complete equipment.
Safe falling proof device at present commonly used is the solenoid actuated formula, namely adopts electromagnet to add pull bar and drives hook or electromagnet and directly drive hook and realize opening and closing of hook, to prevent the weight accidental falling.Because electromagnet and control system thereof easily break down, the safe falling proof device of solenoid actuated formula is also unreliable, and security incident usually takes place.
Summary of the invention
In order to solve the not high difficult problem of the safe falling proof device functional reliability of existing solenoid actuated formula, the utility model provides a kind of mechanical type safe falling proof device, compared with prior art, this device does not have electromagnet and relevant electric-control system, prevent that by mechanical action weight from falling fully, it is reliable to have working stability, lower-cost advantage.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
The safe falling proof device of a kind of mechanical type comprises bearing, the hinged hook that is provided with on the bearing, and a side of hook is corresponding with suspension ring, and the opposite side correspondence is provided with pin, and described pin slides up and down and is connected on the bearing; Be provided with elastomeric element, an end of described elastomeric element is hinged on the bearing, and the other end is hinged on the hook.
Further, described hook four end surface shape are as follows: link up with its right end face corresponding with suspension ring and be obliquely a swing arm, the left end face of hook is a facade; The distance of hook upside end face distance hook pin joint is less than the distance of hook pin joint apart from pin; The hook lower surface apart from the distance of hook pin joint greater than the hook pin joint apart from the distance of pin; When pin was in the top of its stroke, corresponding position was provided with the space that allows the hook rotation and be in open mode between pin and hook.
Further, when the right side of hook turned to front-right, swing arm was towards the top, and the upper surface of swing arm and horizontal angle of inclination are less than swing arm lower surface and horizontal angle of inclination.
Further, described hook upside end face is arc surface; Following end face is at least a of plane or inclined-plane or arc surface; Four end face rounding ofves of hook.
Further, described pin is provided with slotted hole along its glide direction, and pin is hinged at slotted hole place and bearing.
Further, described bearing top is dull and stereotyped, and the below is provided with biside plate, and described bearing, elastomeric element, hook are hinged in the space that forms between the biside plate.
Further, described elastomeric element is extension spring.
Further, also include a joint, an end of joint with the hook hinged, the other end articulates extension spring, the other end of extension spring is hinged on the bearing.
Operating principle of the present utility model and beneficial effect show:
The safe falling proof device of this mechanical type mainly is made up of bearing, hook, pin and elastomeric element.
Its shape and structure and annexation are as follows:
Elastomeric element one end is hinged on the bearing, and the other end is hinged on the hook, as the reset drives power of hook.
Hook: adopt bearing pin hinged and formed by four faces with bearing: the upper and lower, left and right end face; Wherein the corresponding contact with suspension ring of definition hook one end face is its right end face of hook, corresponding other each faces of residue; Its right end face is the swing arm that suspension ring drive in four end faces, the radius of gyration of the upper end cambered surface of linking up with in the rotation process is less than the distance of hook pin joint to pin, thereby guarantee in the upper surface of linking up with when pin rotates, the stress of pin and hook reduces gradually and disappears, and makes that pin can be to lower slider under the gravity of self; And left end face can effectively contact with pin, and contact force satisfies pin at least relative slip can not take place with hook; The lower surface of linking up with in the rotation process greater than the distance of hook pin joint to pin, cooperates pin to form the opening and closing of linking up with apart from the distance of pin joint.
Can slide up and down along support on the pin, and cooperate with hook and to make hook be in to open or closing state that the pin profile adopts rectangular structure, one segment length hole is arranged at top, the middle part is entity for one section, and one section space is arranged at the bottom, to realize the open mode of hook.
Described bearing top is dull and stereotyped, the below be rectangular tube or U-shaped bending part or U-shaped weldment, and wideer two in below wear circular hole, is used for installation described hook, pin and spring, two narrower faces have a face portion fluting or slot fully, are used for providing hook swing space.
The two ends state of pin stroke is as follows: hook its upper end cambered surface under the suspension ring effect is rotated towards pin, the stress relieved of pin and hook, pin drops to the lower end of stroke under the effect of deadweight, at this moment, the hook front end can be swung under the effect of external force upward, but cannot swing downwards; Same when pin when the effect of flat board is moved to the stroke upper end position, the hook front end keeps to the front lower place heeling condition, links up with front end and can swing upward under the effect of external force, also can swing downwards.
As seen, the beneficial effects of the utility model are, rely on the mechanical action of self to realize the anti-fall effect of safety, do not need solenoid actuated, reliable operation, and cost is lower.
