Description
Technical field
the utility model relates to a kind of safety tongs shift mechanism, the high sensitivity safety tongs shift mechanism particularly on a kind of home lift Backpack type sedan-chair frame.
Background technology
the general action being controlled safety tongs by velocity limiter, speed limiter wire rope and safety tongs shift mechanism in home lift; When elevator speed exceedes the limited speed of velocity limiter setting, the action of safety tongs shift mechanism lift safety tongs, stop car.In knapsack-type home elevator, generally on Backpack type sedan-chair frame, safety tongs shift mechanism and safety tongs are installed, by safety tongs stop Backpack type sedan-chair frame, thus stop car.
current safety tongs shift mechanism is mostly crank transmission structure, rotated by the crank that rotarily drives of axle, thus drive safety tongs lift arm is carried, make safety tongs stop Backpack type sedan-chair frame, certain inconvenience is there is in this shift mechanism in installation, and interlock synchronism is undesirable, sensitivity is lower.Therefore, existing safety tongs shift mechanism also exists and installs inconvenient, that interlock synchronism is undesirable and sensitivity is lower problem.
Utility model content
the purpose of this utility model is, provides a kind of highly sensitive safety tongs shift mechanism.The utility model can not only conveniently be installed, and also has the advantage that interlock synchronism is desirable and highly sensitive.
the technical solution of the utility model: highly sensitive safety tongs shift mechanism, comprises gangbar, is provided with velocity limiter lift arm in the middle part of gangbar; Gangbar both ends are equipped with retracing spring, and gangbar two ends are all connected with safety tongs lift arm by pipe link; One end of described gangbar is also connected with UKS switch and re-packs, and is provided with UKS switch below UKS switch re-packs.
in aforesaid highly sensitive safety tongs shift mechanism, described velocity limiter lift arm is positioned at level attitude and perpendicular to gangbar, velocity limiter lift arm one end is connected with wheel carrier, is provided with rope sheave in wheel carrier.
in aforesaid highly sensitive safety tongs shift mechanism, one end of described UKS switch is provided with UKS switch contact, and UKS switch contact connects UKS switch and re-packs.
in aforesaid highly sensitive safety tongs shift mechanism, described gangbar is fixedly connected with velocity limiter lift arm, pipe link and UKS switch and re-packs, and the connection between safety tongs lift arm and pipe link is for being flexibly connected.
compared with prior art, the utility model improves safety tongs shift mechanism structure, moves gangbar rotate by velocity limiter lift arm straps, gangbar drives pipe link to rotate, and pipe link drives on safety tongs lift arm and carries, and structure is simple, convenient installation, interlock synchronism is desirable; Meanwhile, drive UKS switch to re-pack rotation by gangbar, UKS switch re-packs and unclamps UKS switch contact, and by the power-off of UKS switch control rule elevator main, safety is high.Therefore, the utility model can not only conveniently be installed, and also has the advantage that interlock synchronism is desirable, highly sensitive and safety is high.

being labeled as in accompanying drawing: 1-gangbar, 2-velocity limiter lift arm, 3-retracing spring, 4-pipe link, 5-safety tongs lift arm, 6-UKS switch re-packs, 7-UKS switch, 8-wheel carrier, 9-rope sheave, 10-UKS switch contact, 11-velocity limiter, 12-speed limiter wire rope, 13-safety tongs.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.Highly sensitive safety tongs shift mechanism, forms as shown in Figure 1, 2, comprises gangbar 1, is provided with velocity limiter lift arm 2 in the middle part of gangbar 1; Gangbar 1 both ends are equipped with retracing spring 3, and gangbar 1 two ends are all connected with safety tongs lift arm 5 by pipe link 4; Described gangbar 1 one end is also connected with UKS switch 6, the UKS switch that re-packs and re-packs below 6 and be provided with UKS switch 7.
described velocity limiter lift arm 2 is positioned at level attitude and perpendicular to gangbar 1, velocity limiter lift arm 2 one end is connected with wheel carrier 8, is provided with rope sheave 9 in wheel carrier 8; One end of described UKS switch 7 is provided with UKS switch contact 10, UKS switch contact 10 and connects UKS switch and re-pack 6; Described gangbar 1 is fixedly connected with velocity limiter lift arm 2, pipe link 4 and UKS switch and re-packs 6, and velocity limiter lift arm 2, pipe link 4 and UKS switch re-pack and 6 all can rotate with gangbar 1 and rotate; Connection between safety tongs lift arm 5 and pipe link 4 is for being flexibly connected, and safety tongs lift arm 5 can rotate relative to pipe link 4.
as shown in Figure 2, velocity limiter 11 connects rope sheave 9 by speed limiter wire rope 12, and safety tongs lift arm 5 connects safety tongs 13.When elevator downstream rate is normal constantly, speed limiter wire rope 12 moves downward with elevator, and the speed of speed limiter wire rope 12 and the speed of elevator consistent, velocity limiter lifts arm 2 and keeps level.When elevator downstream rate exceedes 115% of the command speed that velocity limiter 11 limits, when namely elevator downstream rate is greater than the command speed of 1.15 times, velocity limiter 11 action, velocity limiter 11 damp governor steel rope 12, speed limiter wire rope 12 stops moving downward; Because now elevator is also in downward operation, speed limiter wire rope 12 lifts 2 one, arm power straight up by rope sheave 9 and wheel carrier 8 to velocity limiter, velocity limiter lift arm 2 drives gangbar 1 to do left-hand revolution, gangbar 1 drives safety tongs to lift arm 5 upward movement by pipe link 4, safety tongs 13 action, stop elevator; Meanwhile, UKS switch re-packs 6 also with gangbar 1 left-hand revolution, and UKS switch re-packs and 6 unclamps UKS switch contact 10, UKS switch 7 and cut out, thus makes elevator main power-off, guarantees elevator stop motion.Wherein, when speed limiter wire rope 12 pulls velocity limiter to lift arm 2 straight up, because velocity limiter lift arm 2 is horizontal, the torque that gangbar 1 receives is maximum, highly sensitive when velocity limiter lift arm 2 length is constant.
