It is an object of the invention to provide a kind of unidirectional lifting equipment, it can overcome drawbacks described above of the prior art.
A kind of unidirectional lifting equipment of the invention, including：Support frame, the lifting electricity on support frame as described above
Machine, the screw shell driven by the screw rod coupled by lifting motor are carried out the hoistable platform of lifting campaign and are arranged on
Monodirectional locking component on support frame as described above, wherein, the monodirectional locking component is included on support frame as described above and is hingedly connected to
Upper pendulum lock fixed pole and lower swing securing rod at the left and right sides of the screw shell, the screw shell pass through the upper pendulum
The through hole of dynamic securing rod and lower swing securing rod, and the upper pendulum lock fixed pole dextral platform portion upper top pressure spring top pressure
Effect is lower to cause that the upper pendulum lock fixed pole is downward-sloping, so that the upper locking teeth in the through hole of the upper pendulum lock fixed pole
Being engaged with the right flank of the screw shell prevents the latching force of the screw shell slide downward to be formed, the lower swing lock
The sinistral platform portion of fixed pole causes that the lower swing securing rod is downward-sloping under the top pressure effect of lower top pressure spring, so that
Lower locking teeth in the through hole of the lower swing securing rod to be engaged with the left surface of the screw shell and prevent the spiral shell being formed
The latching force of line sleeve slide downward；Thus, the upper pendulum lock fixed pole and lower swing securing rod can allow for lifting motor general
The upward lifting of screw shell and prevent moving downward for the screw shell；Fixedly mounted on the end face of support frame as described above top
There is anticollision cushion pad, the anticollision cushion pad is used to avoid the hoistable platform from being touched with support frame as described above when moving downward
Hit, safety guarantee is used so as to improve.
According to the present invention, due to being hinged swing arm using two, it can be locked from both sides to screw shell, and
And realize the locking for moving downward using the pressure effect of spring and downward angle of inclination；Upward pendulum is utilized simultaneously
Dynamic action, can realize Self-unlocking so as to not interfere with motion upwards.
Brief description of the drawings
Fig. 1 schematically illustrates the overall structure diagram of device of the invention.
Specific embodiment
Embodiments of the present invention are illustrated with reference to Fig. 1.
Reference picture 1, according to a kind of unidirectional lifting equipment of embodiment, including：Support frame 3, on support frame as described above 3
Lifting motor 94, the screw shell 92 that is driven by the screw rod 93 that is coupled by lifting motor 94 carry out the liter of lifting campaign
Drop platform 91 and the monodirectional locking component on support frame as described above 3, wherein, the monodirectional locking component is included in described
Upper pendulum lock fixed pole 81 and lower swing securing rod at the left and right sides of the screw shell 92 are hingedly connected on support frame 3
61, the screw shell 92 passes through the through hole of the upper pendulum lock fixed pole 81 and lower swing securing rod 61, and the upper pendulum lock
The dextral platform portion 82 of fixed pole 81 causes that pendulum lock fixed pole 81 is downward-sloping on described under the top pressure effect of upper top pressure spring 84,
So that the upper locking teeth 83 in the through hole of the upper pendulum lock fixed pole 81 engaged with the right flank of the screw shell 92 with
Formation prevents the latching force of the slide downward of the screw shell 92, and the sinistral platform portion 62 of the lower swing securing rod 61 is in Xia Ding
The top pressure effect of pressing spring 64 is lower to cause that the lower swing securing rod 61 is downward-sloping, so that the lower swing securing rod 61
Through hole in lower locking teeth 63 engaged with the left surface of the screw shell 92 and prevent the screw shell 92 downward being formed
The latching force of slip；Thus, the upper pendulum lock fixed pole 81 and lower swing securing rod 61 can allow for lifting motor 94 by described in
The upward lifting of screw shell 92 and prevent moving downward for the screw shell 92；Fixed peace on the top end face of support frame as described above 3
Equipped with anticollision cushion pad 31, the anticollision cushion pad 31 be used to avoid the hoistable platform 91 when moving downward with the support
Frame 3 is collided, and safety guarantee is used so as to improve.
Valuably or exemplarily, wherein, the dextral platform portion 82 of the upper pendulum lock fixed pole 81 and the upper end of connecting rod 51
It is hinged, sinistral platform portion 62 and the lower end of connecting rod 51 of the lower swing securing rod 61 are hinged, under the sinistral platform portion 62
Side engages with lifting unblock drive rod 22, and the lifting unblock drive rod 22 is driven by unblock motor 21 and lifted；Thus,
Can be pivoted up for the upper pendulum lock fixed pole 81 and lower swing securing rod 61 by motion upwards for the lifting unblock drive rod 22
To be unlocked to the screw shell 92 to allow moving downward for the screw shell 92.
Due to being hinged swing arm using two, it can be locked from both sides to screw shell, and utilize spring
Pressure effect and downward angle of inclination and realize the locking for moving downward；Acted on using upward oscillatory forces simultaneously,
Self-unlocking can be realized so as to not interfere with motion upwards.The device can effectively solve the problem that above mentioned problem of the prior art.
By the way that with upper type, those skilled in the art can be in spirit of the invention and main scope according to reality
Need and specific works pattern makes various changes.These change and modification is each fallen within the scope of protection of present invention.
What above-mentioned example of the invention was merely exemplary, should not be construed as limitation of the present invention.Protection scope of the present invention with
