Description
Technical field
The present invention relates to elevators field, particular but not exclusively relate to a kind of method of designing of anti-fall unit of elevator.
Background technology
When elevator meets accident in some cases, elevator can sharply drop, and damages to the people taking elevator.Particularly when rescue worker to the elevator being stuck in floor gap carry out personnel withdraw time, elevator can fall because of accident, because the car of tenesmus and static body of wall can produce to the object be between the two the effect cut, and some position of the health of evacuating people is cut by the car dropped.How to avoid elevator accidental falling, and then reduce injury to personnel or injures and deaths and become the problem that people need solve.
Summary of the invention
The object of the invention is to solve the problem, and a kind of method of designing of anti-fall unit of elevator is provided.
For this reason, the invention provides a kind of method of designing of anti-fall unit of elevator, described anti-fall unit comprises the support be fastenedly connected with car, first gear, second gear, guide rail, roller, trigger element, connecting rod, elasticity restoring piece, pivot shaft, trigger element is installed on support, by pivot shaft, roller is installed on support rotatably, by pivot shaft, the first gear is installed on support rotatably, guide rail is arranged between the first gear and roller, first gear is meshed with the flank of tooth of guide rail, roller is rolled with the light face of guide rail coordinate, by connecting rod, the second gear is revolved round the sun around the axis of the first gear, make the second gear freely rotate relative to connecting rod simultaneously, second gear and the first gear are engaged each other, the triggering hole coordinated with the trigger end of trigger element is set at connecting rod, trigger end is coordinated with triggering hole plug-in type.
Particularly, when trigger end insert trigger hole time, the second gear on connecting rod is remained on the first gear below and on position away from the flank of tooth of guide rail, that is, make trigger end make the second gear not with the face of guide rail; When trigger end withdraw from trigger hole time, the elastic force effect by elasticity restoring piece makes the second gear on connecting rod near the flank of tooth of guide rail, and makes the face of the second gear and guide rail and engage.
Obviously, when trigger end insert trigger hole time, the second gear on connecting rod is remained on the first gear top and on position away from the flank of tooth of guide rail, that is, make trigger end make the second gear not with the face of guide rail; When trigger end withdraw from trigger hole time, the elastic force effect by elasticity restoring piece makes the second gear on connecting rod near the flank of tooth of guide rail, and makes the face of the second gear and guide rail and engage.
Particularly, when the second gear is not got involved, the second gear and the first gears meshing rotate, and the first gear and guide rail engage each other rotation, when the second gear is got involved, the tooth of the second gear and the tooth of guide rail are mutual to top because of respective sense of motion, again because of the roller position-limiting action in rail back (light face), the application force avoided because producing when the second gear is got involved makes guide rail be out of shape, therefore the first gear can be made, second gear and guide rail three are closely interlocked mutually, make the first gear, second gear and guide rail three are interlocked mutually, due to the second gear and guide rail to top act on prevent the first gear and the second gear engage each other rotation, thus the first gear is stopped operating, namely the first gear also stops the engagement rotation with guide rail, thus prevent the tenesmus of elevator.
Beneficial effect
When elevator normally runs, by on the position that trigger element makes the second gear be maintained at away from the flank of tooth of guide rail, first gear is meshed with the flank of tooth of guide rail, first pinion rotation, and then drive the second pinion rotation, roller rolls along the light face of guide rail, and the degree of freedom of the mechanism be made up of the first gear, the second gear, connecting rod, guide rail, roller is 1, so elevator can normally run up and down, when there is unforeseen circumstances in elevator, trigger element is triggered, trigger end is withdrawn from from the triggering hole of connecting rod, elastic force effect by elasticity restoring piece makes the second gear on connecting rod near the flank of tooth of guide rail, and make the face of the second gear and guide rail and engage, now, first gear, guide rail and the second gear three engage each other, by the first gear, second gear, connecting rod, guide rail, the degree of freedom of the mechanism that roller is formed is 0, so elevator can not run up and down, particularly, because the second gear is positioned at the below of the first gear, elevator has the trend run downwards, the first gear certainly will be made downwards to engage along guide rail, and the second gear be positioned at below the first gear certainly will provide the rotation that a rightabout application force stops the first gear.Therefore, the anti-fall process of elevator is, trigger end triggers, and the elastic force of elasticity restoring piece makes the first gear, the second gear and guide rail form meshing relation keep such meshing relation between two between two, and such meshing relation prevents falling of elevator.
Adopt gears meshing to make the degree of freedom of mechanism be 0, be different from and adopt circle wheel to make degree of freedom be 0, circle wheel easily skids between the flank of tooth of the first gear and track, and then causes elevator to drop; And use gears meshing, the first gear, the second gear can be made, this three of track is interlocked mutually securely, stop the tenesmus of elevator.
