Abstract
The invention discloses a gear-and-rack elevator. The gear-and-rack elevator comprises a power box body fixedly installed below a lift car, a driving gear for driving of a motor is installed in the power box body, the driving gear is meshed with three planet gears evenly distributed along the circumference, each planet gear is meshed with one transmission gear, each transmission gear and a worm of a set of worm gear and worm are coaxial, a synchronous gear is installed on each worm gear shaft, each synchronous gear is meshed with one rack fixedly installed on the shaft wall of the elevator, the synchronous gears rotate on the racks to drive a power box to move up and down, and thus up-and-down movement of the lift car is achieved. 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
Technical field
The present invention relates to a kind of elevator.
Background technology
There are problems in elevator at present:
1, Room door accident major cause: Room door is opening wide, and nobody guards, and does not hang Sign Board again and sets up guard rail.Elevator runs to other floor with maintenance or jiggering mode, and the passenger takes for Room door and opening, and car is just at this layer, and crashes into hoistway, causes the accident.2. every lock in the Room damages no spare part reparation, with the door lock short circuit, has people's elevator behind other layer choosing layer to move automatically with lead, causes the people who passes in and out car to be sheared accident.
2, so the useful major cause of car and sedan-chair: Room door is closed and gate is not closed, during the elevator operation in the car personnel's health lean out that car is outer to cause the accident with the collision of hoistway inwall object.2. maintenance man is at the cage top overhauling elevator, cooperates badly with the ladder work of department, do not stand firm, and elevator starts suddenly, causes the accident of damaging of falling.When 3. car was parallel with counterweight, pin of maintenance man stood in the sedan-chair top, and the another pin stands on the counterweight, and elevator starts suddenly, and the people falls into hoistway and causes the accident.Reasons such as 4. traction machine brake poor stop, hoist ropes skid, Elevator weight sensor kicks the beam, elevator overload cause slips car behind the Elevator landing, and this moment, the passenger jumped in car outward, caused the shearing accident.
3, machine room accident major cause: do not observe the electric shock accidents that the electrical safety operating provisions causes.When 2. needing jiggering, do not cut off the electricity supply, startup suddenly caused the accident after car left limit switch.3. have the people to take elevator in debugging, maintenance elevator process, the maintainer contacts the mechanical rotation position, and hand or clothing are involved in and cause the accident
4, pit accident major cause: when the maintainer worked at pit, the ladder work of department cooperated bad with the maintainer, and the car bottom member causes the accident maintainer's collision.2. pit, sedan-chair top, machine room is constructed simultaneously or overhaul, instrument, object fall the below personnel are injured by a crashing object and cause the accident.3. the maintainer is in pit smoking, and the combustible products that ignites does not have cat ladder again and causes the accident.
5, software fault causes the accident: elevator can not restart after a period of time that has a power failure; Elevator often closes the people at high temperature season; Elevator often stops ladder and loses the position at blind layer region; Newly close the people sometimes and lose the position with elevator; Can not arrive destination and close the people; Elevator often crashes and closes the people.
Situation and the European difference of China are very big, public transport place especially, and flow of the people is much bigger, and is long between the elevator at full load, and the lift facility in the skyscraper provides efficient, quick and comfortable work and living environment to people.If yet elevator use and mis-administration, the life security that jeopardizes the passenger-in-elevator sometimes also can cause great economic loss to infrastructure management company.Therefore the safety management of strengthening elevator is most important.So, design a safety factor height, the elevator that is fit 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 pinion and-rack elevator of favorable working performance.
Technical solution of the present invention is:
A kind of pinion and-rack elevator, it is characterized in that: comprise the power box that is installed in the car below, adorn motor-driven driving gear in the power box, driving gear and three mesh along circumference well-distributed planetary wheel, each planetary wheel and a transmission gear engagement, transmission gear is coaxial with the worm screw of one group of turbine and worm, adorn a synchronizer gear on the turbo-shaft, synchronizer gear and the tooth bar engagement that is packed on the 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.
Arrange at headstock and to be positioned at the tooth bar left and right sides, to prevent the left and right sides track adjusting wheel that is offset about synchronizer gear, left and right sides track adjusting wheel contacts with the left and right side of tooth bar respectively.
Motor adopts the brush electric power system.
At the bottom of the top of tooth bar nearside and tooth bar nearside, arrange infrared to point type elevator detector perpendicularity detector respectively.
With three three tooth bars that planetary wheel is corresponding, be separately positioned on the left and right sides sidewall, back wall of elevator.
The present invention is rational in infrastructure, in the transmission design, adopts the rack-and-gear transmission, and tooth bar is loaded on the hoistway, and gear is loaded in the headstock.By the motor driven gear group, through the worm screw turbo drive, driven gear is walked at tooth bar, drives headstock underdrive on the hoistway.In the design of headstock, headstock partly is loaded on the bottom of car, reduced car rigidity requirement in design, car can be carried out light-weight design.Running part has structurally adopted the combination type of drive of turbine and worm and rack-and-gear, makes elevator steady and efficient in the whole service process.The electric power system of traditional elevator is that maximum problem is exactly power supply instability by one or a few trailing cable power supply.The present invention takes the electric brush type power supply in electric power system, and good stability is not perishable.Control system comprises micro controller system, and micro controller system is connected with inner unlimited receptor and motor; Micro controller system is connected with infrared pickoff.Elevator of the present invention can be realized all functions that present elevator can be realized.
