The utility model has the characteristics of stable running, no noise, raw material saving, high safety factor, etc.

Description

The pinion and-rack elevator

The utility model relates to a kind of improvement of elevator for building.

At present, the pinion and-rack elevator that China's skyscraper is used all has heavier balance weight iron, a large amount of raws MAT'L have not only been wasted, and brought certain safety hazard, simultaneously, owing to adopt single electric machine control, the cage operation is unstable, and noise is also bigger, and cage when operation needs the special messenger to operate.

The purpose of this utility model just is that providing a kind of operates steadily, saving in material, the novel elevating machine that noise is little.

The utility model mainly is made up of parts such as chassis, guide rail bracket, cages.Guide rail bracket is formed by connecting with high strength bolt by the square standard knot, and by attaching parts directly and body of wall fix.Guide rail bracket is fixed on the base.Fixing the tooth bar of installing up and down on the guide rail bracket.Cage is a square, and the bottom is two-layer, and the upper strata is supported on the bottom with spring, and two interlayers are equipped with limit switch, and when overload or unbalance loading, upper strata shake-up limit switch is cut off the electricity supply, and cage can not be promoted.One side of cage is equipped with the door that can promote up and down, and limit switch is equipped with in the top of cage, when opening, touches limit switch, cuts off the electricity supply, and cage can not rise or descend.Guide wheel is equipped with at the cage back side, and guide wheel is pressed on the guide rail bracket, makes guide wheel rise or descend along guide rail bracket.The cage inner face is equipped with control housing and appliance plate, two drive motor and an overrun brake are housed on the appliance plate, drive motor one end is equipped with retarder, retarder outer end connection gear, tooth bar engagement on gear and the guide rail bracket, drive cage and rise, descend, the other end of drive motor is equipped with magnet stopper, and manual clamping handle is housed on the magnet stopper.Fixing gear on the output shaft of overrun brake, meshing with tooth bar.Control housing connects control panel, and rising, decline and stop button are housed on the control panel.

After cage rises, run into when having a power failure, magnet stopper is braked electrical motor, and cage stops, and at this moment, the hand brake handle on the magnet stopper can be spurred downwards, and magnet stopper is lifted, and cage can slowly slide.When magnet stopper was malfunctioning, cage descended fast, and when surpassing certain speed, the overrun brake quick action stops operating gear, prevented that cage from continuing to fall, and guaranteed the safety of the elevator and the person.

The utility model is compared with existing elevator, has operation rapidly, steadily, good braking effect, safety factor height, need not characteristics such as auxiliary stand, do not need balance iron, can reduce steel consumption nearly 50%, installation and maintenance are convenient, but people's goods carry altogether, do not need professional operating personal.
