Abstract
The invention discloses a kind of multi-groove type oil buffer, it includes housing, cylinder body and plunger positioned at the enclosure interior, one end of the cylinder body is connected on oil cylinder seat, the other end of the cylinder body plugs the plunger, provided with buffer oil in cylindrical cavity that the cylinder body, plunger are surrounded, the plunger and the oily contact jaw of the buffer are provided with oil groove, the oil groove according to groove height ordered arrangement, the cylinder body, the periphery of plunger are arranged back-moving spring, and the stage casing of the plunger is provided with postive stop baffle.The present invention can be made the buffering of elevator close to uniform motion, be had the advantages that stable buffering using the damping action of fluid；Under the same conditions, the required stroke of the present invention can reduce half than spring buffer, be particularly suitable for use in quick and express elevator.
Description
Technical field
The present invention relates to the security technology area of lift car, more particularly to a kind of multi-groove type oil buffer.
Background technology
Spring buffer of the prior art is after being impacted, and it makes the kinetic energy and potential energy of car or counterweight for bullet
The elastic deformation energy of spring, due to the reaction force of spring, makes car or counterweight slow down.After spring-compressed is to extreme position, bullet
Spring will discharge the elastic deformation energy in buffering course, and car is still to bounce-back and rises generation shock, the higher ball rebound velocity of stroke speed
It is bigger, cause the shock-absorbing capacity of car or counterweight not steady enough.
The content of the invention
In order to solve the problems existing in background technology, it can buffer car and counterweight it is an object of the invention to provide one kind
Steadily and the short multi-groove type oil buffer of cushion stroke.
To achieve these goals, the technical proposal of the invention is realized in this way：A kind of multi-groove type oil buffer, it
Cylinder body 1 and plunger 2 including housing 7, inside the housing 7, one end of the cylinder body 1 is connected on oil cylinder seat 8, described
The other end of cylinder body 1 plugs the plunger 2, and buffer oil 5, the post are provided with the cylindrical cavity that the cylinder body 1, plunger 2 are surrounded
Plug 2 is provided with oil groove 6 with oily 5 contact jaws of the buffer, and the oil groove 6 is according to the height ordered arrangement of groove, the cylinder body 1, post
The periphery of plug 2 is arranged back-moving spring 4, and the stage casing of the plunger 2 is provided with postive stop baffle 9.
Further, the top of the plunger 2 is provided with cushion pad 3.
Further, the top port of housing 7 is provided with spacing ring 10.
Further, the diameter of the back-moving spring 4 is not more than the diameter of the postive stop baffle 9.
The invention has the advantages that：The present invention can make the buffering of elevator close to even using the damping action of fluid
Speed motion, has the advantages that stable buffering；Under the same conditions, the required stroke of the present invention can reduce one than spring buffer
Half, it is particularly suitable for use in quick and express elevator.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Description of reference numerals：Cylinder body 1, plunger 2, cushion pad 3, back-moving spring 4, buffer oil 5, oil groove 6, housing 7, oil cylinder
Seat 8, postive stop baffle 9, spacing ring 10.
Embodiment
The present invention will be further described in detail below in conjunction with the accompanying drawings.
A kind of multi-groove type oil buffer of the present invention, it includes housing 7, cylinder body 1 and plunger inside the housing 7
2, the top of the plunger 2 is provided with cushion pad 3, the infringement caused when contributing to mitigation car and counterweight to impact buffer.
One end of the cylinder body 1 is connected on oil cylinder seat 8, and the plunger 2, institute are plugged inside the other end of the cylinder body 1
State cylinder body 1, be provided with buffer oil 5 in cylindrical cavity that plunger 2 is surrounded, the plunger 2 is with oily 5 contact jaws of the buffer provided with oil
Groove 6, the oil groove 6 is according to the height ordered arrangement of groove, and the cylinder body 1, the periphery of plunger 2 are arranged back-moving spring 4, the plunger
2 stage casing is provided with postive stop baffle 9, and the diameter of the back-moving spring 4 is not more than the diameter of the postive stop baffle 9.
When being impacted during present invention work by car and counterweight, the plunger 2 is moved downward, and is compressed in the cylinder body 1
The buffer oil 5, the buffer oil 5 sprays to the intracavitary of the plunger 2 by the oil groove 6 of cylindricality, when the oil
After groove highly low is filled up by the buffer oil 5 in groove 6, the flow section of oil can be reduced, it is easy into vortex, make in oil body
Particle mutually hit, rub, convert kinetic energy into heat and dissipate, so as to consume the energy of car or counterweight, make car
Or counterweight gradually slowly stops.
When car or counterweight leave the present invention, the plunger 2 resets, directly upwards in the presence of the back-moving spring 4
Compel to stop by the spacing ring 10 that the top port of housing 7 is set to the postive stop baffle 9, the buffer oil 5 flows back to institute again
State in cylinder body 1, recover normal condition.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, this area is common
Other modifications or equivalent substitution that technical staff is made to technical scheme, without departing from technical solution of the present invention
Spirit and scope, all should cover among scope of the presently claimed invention.
