Abstract
The invention relates to a safe and reliable elevator guide rail. The safe and reliable elevator guide rail comprises a rail bottom, and a rail body which is arranged vertical to the rail bottom; the rail bottom and the rail body are connected to form a reversed T shaped structure; a plurality of groups of ball grooves are uniformly formed in the left surface, the top surface and the right surface of the rail body, and the top left surface and the top right surface of the rail bottom; balls are mounted in the ball grooves, and air bags are arranged in the bottoms of the ball grooves; and an automatic air inflation device for inflating air into the air bags is arranged at the bottom part of the rail bottom. The safe and reliable elevator guide rail adopting the scheme above has the advantages that the frictional force between an elevator guide shoe and the guide rail can be reduced through the balls when an elevator runs normally and thus the friction-cased damage on the guide rail can be reduced; in case of overspeed of the elevator, the air is inflated into the air bags, some balls are propped out from the ball grooves under the extruding effects of the ball grooves and the air bags, the propped-out balls are limited to roll to decelerate the elevator under overspeed, so as to lower down the speed of the elevator under overspeed, and as a result, the overspeed-cased damage can be reduced.
Description
Technical field
The present invention relates to cage guide, be specifically related to a kind of safe and reliable cage guide.
Background technology
Along with skyscraper gets more and more, the demand for elevator also increases gradually.Elevator requires safe and reliable, leveling accuracy, ride comfort etc., and wherein, safe and reliable is elevator performance of paramount importance.Existing safety device comprises as safety tongs, energy disperser etc.; when lift car stall is fallen; safety device can reduce car falling speed to a certain extent; and cushion impact forces, realize the object of protection occupant, but; still there are some drawbacks in existing safety device; such as, energy disperser only has when lift car crouching is hit on energy disperser, and energy disperser just can play the effect of deceleration buffer.
In addition, in prior art, elevator guide shoe is when cage guide surface sliding, and guide rail not to slide restriction to leading boots, guide rail and lead cliding friction between boots, and way rub is very fast.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of safe and reliable cage guide.
Realize technical scheme of the present invention as follows:
A kind of safe and reliable cage guide, comprise the flange of rail and rail body, rail body is arranged perpendicular to the flange of rail, the flange of rail and rail body are connected to form " convex " character form structure, the left rail level of described rail body, head track face, the upper left rail level of right rail level and the described flange of rail, upper right rail level evenly offers some groups of ball grooves, in ball grooves, ball is installed, the bottom land of ball grooves is provided with air bag, described rail body be provided with the passage being communicated with ball grooves bottom land in the flange of rail, the end of passage is located at the bottom of the flange of rail, the appendix connecting each air bag is provided with in passage, the end of appendix stretches out from channel end, the bottom of the described flange of rail is provided with the self-filler inflated air bag.
Further, described ball grooves is truncated cone-shaped, and the bottom surface of round platform is the bottom land of ball grooves.
Further, the rail level on described guide rail evenly offers some velocity response holes for placing speed sensor along rail length direction.
Have employed above-mentioned scheme, when elevator normally runs, ball the friction force that can reduce between elevator guide shoe and guide rail is set, reduce the frictionally damage to guide rail; When stall appears in elevator, inflate air bag, ball ejects ball grooves in the extruding lower part of ball grooves and air bag, the rolling of ball is suppressed, slowed down by the elevator of downtrod ball to stall, reduce speed during elevator stall, lower the harm of stall.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is Fig. 1 birds-eye view;
In figure, 1 is the flange of rail, and 2 is rail body, and 3 is left rail level, and 4 is head track face, and 5 is right rail level, and 6 is upper left rail level, and 7 is upper right rail level, and 8 is ball grooves, and 9 is ball, and 10 is air bag, and 11 is passage, and 12 is appendix, and 13 is gas filled device, and 14 is velocity response hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
See Fig. 1, 2, a kind of safe and reliable cage guide, comprise the flange of rail 1 and rail body 2, rail body is arranged perpendicular to the flange of rail, the flange of rail and rail body are connected to form " convex " character form structure, the left rail level 3 of described rail body, head track face 4, the upper left rail level 6 of right rail level 5 and the described flange of rail, upper right rail level 7 evenly offers some groups of ball grooves 8, ball 9 is installed in ball grooves, the bottom land of ball grooves is provided with air bag 10, described rail body be provided with the passage 11 being communicated with ball grooves bottom land in the flange of rail, the end of passage is located at the bottom of the flange of rail, the appendix 12 connecting each air bag is provided with in passage, the end of appendix stretches out from channel end, the bottom of the described flange of rail is provided with the self-filler 13 inflated air bag.
Further, described ball grooves is truncated cone-shaped, and the bottom surface of round platform is the bottom land of ball grooves.
Further, the rail level on described guide rail evenly offers some velocity response holes 14 for placing speed sensor along rail length direction.Velocity response hole can be located at left rail level, head track face, right rail level on upper left rail level or upper right rail level.
When elevator normally runs, air bag unaerated, air bag remains and is in ball grooves bottom land, and ball movable space in ball grooves is large; Ball or be in ball grooves does not completely contact with elevator, or part is in ball grooves and contacts with elevator, ball the friction force that can reduce between elevator guide shoe and guide rail is set, reduce the frictionally damage to guide rail.
Elevator is provided with the groove adapted with the sphere of ball, when stall appears in elevator, inflates air bag, ball ejects ball grooves in the extruding lower part of ball grooves and air bag, and the rolling of ball is suppressed, under the extruding of air bag, ball embeds in groove, thus slows down to elevator.
Ball grooves truncated cone-shaped is arranged, and the bottom surface of round platform is the bottom land of ball grooves, so arranges and ball can be avoided to depart from ball grooves, is convenient to air bag and ball grooves extrudes ball, thus the rolling of ball is suppressed.
Speed sensor the speed can monitoring elevator is set, when elevator stall, speed sensor provides elevator stall signal, and the signal that self-filler inbound pacing inductor sends is inflated air bag.
The present invention effectively improves the safety that elevator runs.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
