Description
Technical field
The present invention relates to jacking equipment field, especially a kind of unidirectional lifting drive device.
Background technology
In jacking equipment, for the danger that the lifting of article often faces unexpected landing.Can using screw thread lowering or hoisting gear
To avoid this kind of danger.But, screw thread form may be caused to damage for the long-term compression of weight, increase deformed threads risk simultaneously
Possible reduction of service life.
The content of the invention
It is an object of the invention to provide a kind of unidirectional lifting drive device, it can overcome of the prior art above-mentioned scarce
Fall into.
A kind of unidirectional lifting drive device of the invention, including：Support frame, the lifting on support frame as described above
Motor, the screw shell driven by the screw rod coupled by lifting motor carry out hoistable platform and the installation of lifting campaign
Monodirectional locking component on support frame as described above, wherein, the monodirectional locking component is included on support frame as described above and is respectively articulated with
Upper pendulum lock fixed pole and lower swing securing rod at the left and right sides of the screw shell, the screw shell are passed through on described
The through hole of pendulum lock fixed pole and lower swing securing rod, and the upper pendulum lock fixed pole dextral platform portion on the top of upper top pressure spring
Pressure effect is lower to cause that the upper pendulum lock fixed pole is downward-sloping, so that the upper locking in the through hole of the upper pendulum lock fixed pole
Tooth engages with the right flank of the screw shell and the latching force of the screw shell slide downward is prevented to be formed, the lower swing
The sinistral platform portion of securing rod 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 engage with described in being formed and preventing with the left surface of the screw shell
The latching force of screw shell slide downward；Thus, the upper pendulum lock fixed pole and lower swing securing rod can allow for lifting motor
The upward lifting of the screw shell is prevented into moving downward for the screw shell.
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 drive device of embodiment, including：Support frame 3, installed in the support
Lifting motor 94 on frame 3, the screw shell 92 driven by the screw rod 93 coupled by lifting motor 94 carry out lifting fortune
Dynamic hoistable platform 91 and the monodirectional locking component on support frame as described above 3, wherein, the monodirectional locking component includes
Upper pendulum lock fixed pole 81 and the lower swing lock being hingedly connected on support frame as described above 3 at the left and right sides of the screw shell 92
Fixed pole 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
The dextral platform portion 82 of dynamic securing rod 81 causes that pendulum lock fixed pole 81 is downward on described under the top pressure effect of upper top pressure spring 84
Incline, so that the upper locking teeth 83 in the through hole of the upper pendulum lock fixed pole 81 connects with the right flank of the screw shell 92
Conjunction prevents the latching force of the slide downward of the screw shell 92 to be formed, and the sinistral platform portion 62 of the lower swing securing rod 61 exists
The top pressure effect of lower top pressure spring 64 is lower to cause that the lower swing securing rod 61 is downward-sloping, so that the lower swing is locked
Lower locking teeth 63 in the through hole of bar 61 to be engaged with the left surface of the screw shell 92 and prevent the screw shell 92 being formed
The latching force of slide downward；Thus, the upper pendulum lock fixed pole 81 and lower swing securing rod 61 can allow for the general of lifting motor 94
The upward lifting of the screw shell 92 and prevent moving downward for the screw shell 92.
Valuably or exemplarily, wherein, the dextral platform portion 82 of the upper pendulum lock fixed pole 81 is nearby and connecting rod 51
Upper end is hinged, and the sinistral platform portion 62 of the lower swing securing rod 81 is nearby hinged with the lower end of connecting rod 51, the sinistral platform
The downside in portion 62 engages with lifting unblock drive rod 22, and the lifting unblock drive rod 22 is driven by unblock motor 21 and risen
Drop；Thus, motion can be by the upper pendulum lock fixed pole 81 and lower swing securing rod 61 upwards for the lifting unblock drive rod 22
It is pivoted up unlocking 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
Appended claim is defined.
