Description
Technical field
The present invention relates to a kind of elevator technology field, specifically a kind of self adaptation buffer of elevator with feedback.
Background technology
Buffer is arranged on the bottom of elevator hoistways, when lift car or counterweight fall, can play last buffering,
Stop and protective effect, in order to avoid car or counterweight directly hit bottom, the buffering effect of current Buffer for elevator is not good, and it is general
Realize the buffering of elevator by spring or hydraulic damping, but because the characteristic of spring or damping itself makes its buffer intensity be
Fixing it is impossible to automatically adjust buffer intensity for different elevator speeds, and it is known that lift car is in differing heights
When falling, speed when it is contacted with buffer is different, and the buffering therefore to realize elevator with fixing buffer intensity subtracts
Less it is clear that being inappropriate, being therefore badly in need of one kind can be according to the self-reacting buffer of used during elevator falling speed.
Content of the invention
It is an object of the invention to provide a kind of self adaptation buffer of elevator with feedback, to solve in above-mentioned background technology
The problem proposing.
For achieving the above object, the following technical scheme of present invention offer:
A kind of self adaptation buffer of elevator with feedback, including oil cylinder, is provided with piston in described oil cylinder, and described piston leads to
Cross piston rod to be fixedly linked with the baffle plate above oil cylinder, between described baffle plate lower end and cylinder upper end, be provided with spring；Described gear
Plate upper end is provided with installation case, is provided with programmable plc controller, is provided with inlet wire on the right side of described installation case in described installation case
Hole；Described installation case upper end is provided with and hits plate, described hit lower end on the right side of plate and be provided with velocity measuring module, described plate upper end of hitting sets
It is equipped with cushion pad；Described piston is symmetrically set with the through hole of two upper and lower both sides of connection, and described through hole upper end is provided with resistance
Buddhist nun hole；It is provided with solenoid, described solenoid both sides are symmetrically arranged with horizontally disposed in piston between described through hole
Magnet controlled marmem post, extends to damping in the hole outside described magnet controlled marmem post；Described solenoid
Electrically connected with velocity measuring module by programmable plc controller.
As the further scheme of the present invention: described installation case has high-strength steel sheet to make.
As the present invention further scheme: be provided with described piston rod conveniently line cable-through hole.
Compared with prior art, the invention has the beneficial effects as follows: this new in buffering be made up of two parts, a part is
Spring constitute quantitation buffering, another part be piston on damping hole variable buffering, spring can in elevator cab folding process,
Deformation quantity in per stroke be certain be therefore quantitative buffering, and damping hole is in elevator cab folding process, and speed is examined
Survey module and detect that elevator cab collides the real-time speed signal after moving down, and feed back to programmable plc controller, programmable plc
Controller can program in advance, the real-time current size of corresponding speed signal real-time control solenoid, therefore can real-time regulation electricity
The magnetic field intensity of magnetic coil, and then change the radial dimension of magnet controlled marmem post, thus realizing the throttling of damping hole
The real-time change of area, to reach the real-time purpose changing damped coefficient with this, realizes adaptive variable buffering.
In sum, this new form by quantitative buffering and variable buffering, speed when can be collided according to elevator cab
Degree feedback changes the damped coefficient of damping hole in real time, thus reaching adaptive buffering course, it is to avoid existing buffer exists difficult
To meet shortcoming during different impact velocity, so that buffering is a more reasonably progressive formation.
