The gear-and-rack elevator is reasonable in structure, in transmission design, gear-and-rack transmission is adopted, the racks are installed on a shaftway, and the gears are installed in the power box. Gear sets are driven by the motor, transmission is achieved through the worms and the worm gears to drive the gears to walk on the racks, and then the power box is driven to be in transmission on the shaftway up and down.

Description

Gear-and-rack elevator

Technical field

The present invention relates to a kind of elevator.

Background technology

There are problems in current elevator:

1, Room door accident major cause: Room door opens, and nobody guards, does not hang again Sign Board and sets up guard rail.Elevator maintenance or jiggering mode run to other floor, and passenger takes for Room door and opens, and car just at this layer, and crashes into hoistway, causes the accident.2. Room door lock damages without spare part reparation, with wire by door lock short circuit, has people's elevator after other layer selects layer automatically to run, causes the people passing in and out car to be sheared accident.

2, car and the useful therefore major cause of sedan-chair: Room door is closed and gate is not closed, when elevator runs, in car, personnel's health leans out the outer and hoistway inwall object of car and bumps against and cause the accident.2. maintenance man is at cage top overhauling elevator, and coordinate bad with department ladder work, do not stand firm, elevator starts suddenly, causes the accident of damaging of falling.3., when car is parallel with counterweight, maintenance man feet station is on sedan-chair top, and another feet station is on counterweight, and elevator starts suddenly, and people falls into hoistway and causes the accident.4. slip car after the reason such as traction machine brake poor stop, hoist ropes skids, Elevator weight sensor kicks the beam, elevator overload causes Elevator landing, now passenger jumps outward in car, causes shearing accident.

3, machine room accident major cause: do not observe the electric shock accidents that electrical safety operating provisions causes.When 2. needing jiggering, do not cut off the electricity supply, start suddenly after car leaves limit switch and cause the accident.3. in debugging, maintenance elevator process, have people to take elevator, maintainer contacts mechanical rotation position, and hand or clothing are involved in and cause the accident

4, pit accident major cause: maintainer is when pit works, and department ladder work coordinates bad with maintainer, maintainer's collision causes the accident by cage bottom component.2. pit, sedan-chair top, machine room carry out constructing or overhauling simultaneously, and instrument, object fall below personnel to injure by a crashing object and cause the accident.3. maintainer is in pit smoking, and ignite combustible products, causes the accident again without cat ladder.

5, software fault causes the accident: elevator, after power failure a period of time, can not restart; Elevator often closes people at high temperature season; Elevator often stops ladder at blind layer region and loses position; Newly sometimes close people with elevator and lose position; Can not destination be arrived and close people; Elevator often crashes and closes people.

The situation of China and European difference are very large, and especially public transport place, flow of the people is much bigger, and the elevator cars with full load time is long, and the lift facility in skyscraper provides efficient, quick and comfortable work and living environment to people.If but elevator uses and mis-administration, jeopardizes the life security of passenger-in-elevator sometimes, also can cause great economic loss to infrastructure management company.Therefore the safety management strengthening elevator is most important.So design a safety factor high, the elevator being applicable to Chinese situation is extremely urgent.

Summary of the invention

The object of the present invention is to provide a kind of rational in infrastructure, the Gear-and-rack elevator of favorable working performance.

Technical solution of the present invention is:

A kind of Gear-and-rack elevator, it is characterized in that: comprise the power box be installed in below car, motor-driven driving gear is filled in power box, driving gear with three circumferentially well-distributed planetary wheel engage, each planetary wheel engages with a transmission gear, transmission gear is coaxial with the worm screw of one group of turbine and worm, turbo-shaft fills a synchronizer gear, synchronizer gear engages with the tooth bar be packed in hoistway wall, by the rotation of synchronizer gear on tooth bar, drive the up-and-down movement of headstock, and then realize the up-and-down movement of car.

Headstock is arranged be positioned at the tooth bar left and right sides, prevent synchronizer gear about the left and right track adjusting wheel that offsets, left and right track adjusting wheel contacts with the left and right side of tooth bar respectively.

Motor adopts brush electric power system.

At the top nearside of tooth bar and the bottom nearside of tooth bar, arrange infrared to point type elevator detector perpendicularity detector respectively.

Three tooth bars corresponding with three planetary wheels, are separately positioned in the left and right sidewall of elevator, back wall.

The present invention is rational in infrastructure, and on driven Design, adopt rack pinion, tooth bar is loaded on hoistway, and gear is loaded in headstock.By motor driven gear group, through worm screw turbo drive, driven gear, tooth bar is walked, drive headstock on hoistway on underdrive.In the design of headstock, headstock part is loaded on the bottom of car, reduces car rigidity requirement in design, car can be carried out light-weight design.Running part structurally have employed the combination type of drive of turbine and worm and rack-and-gear, makes elevator steadily efficient in whole service process.The electric power system of traditional elevator is powered by one or a few trailing cable, and maximum problem is exactly power supply instability.The present invention takes electric brush type to power in electric power system, and good stability is not perishable.Control system comprises micro controller system, and micro controller system is connected with the unlimited receptor in inside and motor; Micro controller system is connected with infrared pickoff.Elevator of the present invention can realize all functions achieved by current elevator.
