Therefore, it is necessary to providing a kind of new kind of drive replaces hydraulicdriven door frame lowering or hoisting gear.
The content of the invention
It is an object of the invention to provide a kind of door frame lowering or hoisting gear, and hydraulic cylinder, motor are replaced by ball screw assembly,
Transfer torque on ball screw assembly, so that hoisting mechanism steadily operates.
To achieve these goals, the present invention proposes a kind of door frame lowering or hoisting gear, including：
Ball-screw, the ball-screw are arranged inside door frame both sides；
A pair of nuts, the nut are arranged on the ball-screw, are moved up and down along the ball-screw；
Drive device, the drive device are used to drive the ball-screw to rotate；
Brake apparatus, the ball-screw bottom is arranged at, for preventing the ball screw turns.
Preferably, the pair of nut is connected by crossbeam.
Preferably, the crossbeam is provided with goods shelf.
Preferably, the drive device is arranged at the ball-screw top.
Preferably, be provided with a pair of arcuate friction pieces inside the brake apparatus, the friction plate by air-leg with it is described
Brake apparatus connects.
Preferably, the ball-screw is arranged among the pair of arcuate friction piece.
Preferably, it is provided with guard rail on rear side of the door frame.
Preferably, the drive device is motor.
The beneficial effects of the present invention are：Hydraulic cylinder is replaced by ball-screw, motor can transmit torque to
On ball-screw, leading screw rotates, and nut moves along a straight line up and down along leading screw, and nut drives the pallet fork oscilaltion on crossbeam so that
The mechanism of whole hoisting mechanism is simple, and transmission is convenient；Main loss is the friction loss of fluid pressure line and each in hydraulic drive
The pressure loss at valve is planted, therefore the energy loss of the part can be reduced using ball-screw, improves the machine of portal frame system
Tool efficiency.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
