Description
Technical field
The utility model relates to the crane field, but is specially the scissors fork lowering or hoisting gear of a kind of precisely controlling displacement self-locking.
Background technology
The cold rolled strip steel production line, in running, often needs to use elevating mechanism, to the requirement of elevating mechanism, is can respond rapidly, compact conformation, and position can accurately be controlled, and realizes mechanical self-latching etc.In practical application at present, usually drive realization by pneumatic or hydraulic pressure, although these modes can meet the part requirement, but structure is more complicated, appearance and size is larger, oil liquid leakage easily occurs, can not realize mechanical self-latching etc. simultaneously, have defect aspect safety and stability, the occasion higher at ask for something can't be used.
The utility model content
In order to overcome the defect of prior art, provide a kind of simple in structure, easy to use, control accurate, safe and reliable jacking equipment, but the utility model discloses the scissors fork lowering or hoisting gear of a kind of precisely controlling displacement self-locking.
The utility model reaches goal of the invention by following technical solution:
But the scissors of a kind of precisely controlling displacement self-locking fork lowering or hoisting gear, comprise upper bed-plate and lower bottom base, upper bed-plate and lower bottom base be arranged in parallel, it is characterized in that: also comprise scissors fork connecting rod, slide block, slide rail and electric pushrod, one side of upper bed-plate and lower bottom base is all fixed a slide rail, slide block of each embedding in slide rail, slide block moves along slide rail; Between upper bed-plate and lower bottom base, with scissors fork connecting rod, connect, a side of scissors fork connecting rod is stiff end, and the stiff end of scissors fork connecting rod is separately fixed at by bearing pin the end that upper bed-plate and lower bottom base are positioned at homonymy; The opposite side of scissors fork connecting rod is mobile terminal, and the mobile terminal of scissors fork connecting rod connects respectively a slide block; The stiff end of electric pushrod is fixed on lower bottom base, a connection of the telescopic end of electric pushrod and scissors fork connecting rod.Electric pushrod inside is the trapezoidal screw pair, uses lead screw transmission, can realize mechanical self-latching.
But the scissors of described precisely controlling displacement self-locking fork lowering or hoisting gear, it is characterized in that: also comprise rotary encoder and school zero approach switch, the motor afterbody of electric pushrod is provided with rotary encoder, school zero approach switch is located on lower bottom base, between zero approach switch of rotary encoder and school, by order wire, connects.
When the utility model is used, lower bottom base is fixed on to basis upper, needs the workpiece of lifting to be fixed on upper bed-plate; By the stretching out or retract and drive the scissors fork and swing of electric pushrod telescopic end, thereby realize rising or the decline of upper bed-plate; After rising to the expection height, the outage of the motor of electric pushrod, electric pushrod relies on the leading screw self-locking, keeps stable and can automatic descending, guarantees the workpiece practical function be lifted.If be provided with rotary encoder and school zero approach switch, first zero by zero approach switch school, school before rising, according to the parameter relationship formula of electric pushrod stroke and upper bed-plate vertical lift stroke, rotary encoder calculates the stroke of electric pushrod and drives the electric pushrod action subsequently; Can realize so the accurate location of lifting travel.
The beneficial effects of the utility model are: simple and compact for structure, easy to use, flexible for installation, and other equipment are without interference, can respond rapidly, position can accurately be controlled, and can realize mechanical self-latching, aspect safety and stability, outstanding advantage is arranged.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the present utility model with rotary encoder and school zero approach switch.
The specific embodiment
Below further illustrate the utility model by specific embodiment.
But the scissors of a kind of precisely controlling displacement self-locking fork lowering or hoisting gear, comprise upper bed-plate 1, lower bottom base 2, scissors fork connecting rod 3, slide block 4, slide rail 5 and electric pushrod 6, and as shown in Figure 1, concrete structure is:
Upper bed-plate 1 and lower bottom base 2 be arranged in parallel; One side of upper bed-plate 1 and lower bottom base 2 is all fixed a slide rail 5, slide block 4 of each embedding in slide rail 5, and slide block 4 moves along slide rail 5; Between upper bed-plate 1 and lower bottom base 2, with scissors fork connecting rod 3, connect, a side of scissors fork connecting rod 3 is stiff end, and the stiff end of scissors fork connecting rod 3 is separately fixed at by bearing pin the end that upper bed-plate 1 and lower bottom base 2 are positioned at homonymy; The opposite side of scissors fork connecting rod 3 is mobile terminal, and the mobile terminal of scissors fork connecting rod 3 connects respectively a slide block 4; The stiff end of electric pushrod 6 is fixed on lower bottom base 2, a connection of the telescopic end of electric pushrod 6 and scissors fork connecting rod 3.Electric pushrod 6 inside are the trapezoidal screw pair, use lead screw transmission, can realize mechanical self-latching.
When the present embodiment is used, lower bottom base 2 is fixed on to basis upper, needs the workpiece of lifting to be fixed on upper bed-plate 1; By the stretching out or retract and drive scissors fork 3 and swing of electric pushrod 6 telescopic ends, thereby realize rising or the decline of upper bed-plate 1; After rising to the expection height, the outage of the motor of electric pushrod 6, electric pushrod 6 relies on the leading screw self-lockings, keeps stable and can automatic descending, guarantees the workpiece practical function be lifted.In Fig. 1, double dot dash line is depicted as the imaginary drawing after the present embodiment lifting.
