Abstract
The utility model relates to a lift speed limiter without a machine room which belongs to a lift safety element. The publicly known speed limiter can not simultaneously satisfy the requirement that the speed limiter is installed at the top of a wall way, an access door does not need to be installed, and the speed limiter has the accessibility which conforms to the standard requirement. When the utility model is adopted, the main body of the speed limiter and an auxiliary guide wheel are fixedly installed on the top of a lift car, a rope clamping device of the speed limiter is fixedly installed at the upper part of a side beam of a car box and is positioned at the upper part of the main body of the speed limiter, and the rope clamping device of the speed limiter can do the relative motion within a definite range. One end of a rope of the speed limiter is fixed on the top surface or a cross beam of the well way, and the other end of the rope of the speed limiter is connected and fixed to a tight-expanding counter weight in a bottom pit as a ring-opening type circling mode. The utility model has the advantages of unique and novel installing position, simple and reasonable structure, cheap price, easy installation and easy repair. The blank in the prior art is filled when the utility model is adopted.
Description
The utility model relates to a kind of speed limiter for elevator, is particularly suited for the machine-roomless lift velocity limiter, belongs to the elevator safety parts.
Velocity limiter is the device of a kind of restriction car (or counterweight) speed.Public velocity limiter is installed in the machine room, also has in the top or pit that is contained in hoistway, and swelling device places in the pit, must satisfy personnel's accessibility according to the elevator standard regulation.For this reason, offer an access door in the hoistway corresponding position usually, cost is high and be not suitable for machine-roomless lift.If on real velocity limiter, set up a remote control gear, then make structure complicated more, cost improves.Up to now, elevator industry none invention still both at home and abroad can be satisfied the accessibility of standard-required, does not need to offer access door again and realizes easily installing and maintenance, and simple and reasonable, uses reliable and stablely, is particularly suited for the machine-roomless lift velocity limiter.
The purpose of this utility model provides a kind of New Speed Limiter, and it is particularly suited for the machine-roomless lift velocity limiter, thereby fills up the blank in the reality technology.This device is the change to reality technology, structure, installation site and winding of the wire rope.
Concrete technology contents of the present utility model is: a kind of machine-roomless lift velocity limiter, it comprises velocity limiter main body (1), velocity limiter rope gripper (2), governor rope (3), auxiliary guide wheels (4) and tensioner weight (5) five most of formations, wherein: the bearing (6) of velocity limiter main body (1) and the bearing (7) of auxiliary guide wheels (4) are all adorned solid on (8) top, sedan-chair top respectively, it is characterized in that: velocity limiter rope gripper (2) is then adorned solid on car curb girder (9) top, and is fixed as one with connecting rod (10); Governor rope (3) one ends are fixed on hoistway end face (11) or the crossbeam, and the other end becomes open loop type to wear in regular turn to walk around rope gripper (2), velocity limiter main body (1), auxiliary guide wheels (4), the tensioner weight (5) in being fixed on pit; Velocity limiter rope gripper (2) must be positioned at velocity limiter main body (1) top, and the relative motion of certain limit is arranged.
Had unique novel, simple and reasonable, the low price in installation site, easily installed and keep in repair by the elevator governor of last acquisition, it is particularly useful for using in the machine-roomless lift.It can satisfy the accessibility of standard code, can guarantee the safe, stable, reliable of performance again.The present invention has filled up
The blank of prior art.
Accompanying drawing 1 is a scheme drawing of the present utility model.
Further describe structure of the present utility model and principle of work below in conjunction with accompanying drawing.Velocity limiter main body (1) is similar substantially to existing structure with velocity limiter rope gripper (2), but the installation site is different with mode; Wherein velocity limiter main body (1) is made of velocity limiter main wheel (1) and bearing (6); Velocity limiter rope gripper (2) is made of bearing, connecting rod, swing pincers piece, locking bolt, overspeed switch, fixed clamp block and two springs etc.; Rope gripper (2) be can guarantee and velocity limiter main body (1) between the relative motion of certain limit is arranged.Auxiliary guide wheels (4) is an additional article, works to change governor rope (3) direction.The principle of work of this device is: when elevator normally moves, do not have relative motion between velocity limiter rope gripper (2) and the velocity limiter main body (1); And quicken to rotate when the elevator tenesmus makes the velocity limiter main wheel, get rid of piece on the main body outwards to throw the bump overspeed switch owing to action of centrifugal force away and cut off the elevator control path, magnet stopper power-off brake elevator; If elevator continues to quicken tenesmus, the piece that gets rid of on the velocity limiter main body (1) also continues outer get rid of and clash into locking bolt, removes the swing pincers piece behind the locking bolt, under the spring tension effect and on carry, governor rope (3) is clamped on the fixed clamp block, and connecting rod (10) drives the action of safety tongs interlinked mechanism.Guarantee the safety of elevator motion and accident steadily with this.
Claims (1)
1, a kind of machine-roomless lift velocity limiter, it comprises velocity limiter main body (1), velocity limiter rope gripper (2), governor rope (3), auxiliary guide wheels (4) and tensioner weight (5) five most of formations, wherein: the bearing (6) of velocity limiter main body (1) and the bearing (7) of auxiliary guide wheels (4) are adorned solid on (8) top, sedan-chair top respectively, it is characterized in that: velocity limiter rope gripper (2) is then adorned solid on car curb girder (9) top, and is fixed as one with connecting rod (10); Governor rope (3) one ends are fixed on hoistway end face (11) or the crossbeam, and the other end becomes open loop type to wear in regular turn to walk around rope gripper (2), velocity limiter main body (1), auxiliary guide wheels (4), the tensioner weight (5) in being placed on pit; Velocity limiter rope gripper (2) must be positioned at velocity limiter main body (1) top, and the relative motion of certain limit is arranged.
