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
The present invention relates to a kind of bont, especially for the construction elevator of building and other industries.
Background technology
Existing on the market construction elevator all adopts pinion and-rack mostly, and it is to utilize the motion of gear on tooth bar to finish lifting work, exists shortcomings such as noise is big, easy to wear.Advantages such as the present invention utilizes the rotation of screw rod on tooth bar to finish lifting work, safety is arranged, be difficult for tenesmus, and noise is little, and is not easy to wear.
Summary of the invention
Of the present invention day be to provide a kind of jacking system that can be used for industry such as construction elevator safe and reliable, simple in structure.The present invention is on the basis of existing gear rack type construction elevator, the gear that lifting is used changes screw rod into, and (screw flight progression can be as required, arbitrarily add and subtract during design), crowngear is set (if use angular gear respectively at the two ends up and down of screw rod, motor is then used screw mandrel), a connection motor lifting effect, a connection falling protector plays anti-fall effect.Tooth bar is designed to the helical teeth (like this can be better with the faying face of lifting screw, area of contact is bigger, helps the operation up and down of elevator) of half arcs of recesses the same with the radian of lifting screw.
Description of drawings
Accompanying drawing is lifting screw, linear gear and lifting tower scheme drawing.
The specific embodiment
On the basis of existing pinion and-rack cage lifter, tooth bar is designed to the diagonal-cut rack of the dished consistent with the radian of lifting screw, and is installed in the middle of lifting tower side, and the front of tooth bar is towards lift car.Installation lifting screw on car, and make lifting screw and tooth bar coincide, sting tight, gear or crowngear (diameter after the diameter of gear must be deducted tooth depth less than lifting screw) are installed respectively at the two ends up and down of lifting screw, are connected motor and falling protector more respectively.Other parts are the same with existing gear rack type construction elevator.
Claims (5)
1. the jacking system of a construction elevator is characterized in that using lifting screw and linear gear.
2. it is characterized in that according to claim 1 the screw thread progression of lifting screw is the amount doesn't matter.
3. it is characterized in that according to claim 1 linear gear is installed in the middle of the lifting tower side, and tooth bar is just facing lift car.
4. it is characterized in that according to claim 1 direction of the tooth of linear gear is oblique.
5. it is characterized in that according to claim 1 front of linear gear is recessed and radian is arranged, its radian is close with lifting screw cylindrical radian.
