Embodiment Construction

[0005] On the basis of the existing rack-and-pinion elevator, the rack is designed as a semi-concave helical rack that is consistent with the radian of the lifting screw, and is installed in the middle of the side of the elevator tower, and the front of the rack faces elevator car. Install the lifting screw on the top of the car, and make the lifting screw match and bite the rack, and install gears or bevel gears on the upper and lower ends of the lifting screw (the diameter of the gear must be smaller than the diameter of the lifting screw after deducting the tooth depth) , and then connect the motor and the anti-dropping device respectively. Other parts are the same as the existing rack and pinion type construction elevator.

Abstract

The invention relates to a lifting device for a construction elevator. The conventional construction elevators in the market are in a gear rack type mostly, the lifting work is completed by moving a gear on a rack, and defects of large noise, high possibility of being worn and the like exist. The lifting work is completed by rotating a screw rod on the rack, and the lifting device has the advantages of safety, low possibility of dropping and being worn, small noise and the like.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a construction elevator used in construction and other industries. Background technique [0002] Most of the existing construction elevators on the market adopt the rack-and-pinion type, which uses the movement of the gear on the rack to complete the lifting work, which has the disadvantages of loud noise and easy wear and tear. The present invention uses the rotation of the screw rod on the rack to complete the lifting work, which has the advantages of safety, not easy to fall, low noise, not easy to wear and the like. Contents of the invention [0003] The object of the present invention is to provide a safe, reliable, and simple-structure lifting system that can be used in industries such as construction elevators. On the basis of the existing rack-and-pinion type construction elevator, the present invention changes the gear used for lifting into a screw (the number of thread stages of ...
