Description
Technical field
The present invention relates to a kind of elevator gear, relate in particular to a kind of numerical control turning suspension cage.
Background technology
Existing crane equipment is that the control mechanism that hoists connects cage by one or a few lifting rope mostly, and the rise of control cage or fall.In use, can't avoid and prevent accidents such as off-axis, gear tooth breakage, and in the work of long-term abominable place, its lifting rope is easy to occur phenomenons such as distortion, corrosion, wearing and tearing, local section contraction, greatly reduce the safety performance of crane equipment, directly threatened staff's life security.Similar in the market crane equipment can't be under environment such as inclination flue normal operation, range of use was restricted when it was used, and was difficult to satisfy user demand.
Summary of the invention
The purpose of this invention is to provide a kind of numerical control turning suspension cage, to overcome existing installation poor safety performance, the restricted deficiency of range of use.
Realize that technical scheme of the present invention is as follows:
A kind of numerical control turning suspension cage, comprise lifting mechanism and cage, lifting mechanism connects cage by lifting rope, described lifting mechanism is by electrical motor, retarder, main drum and loose drum are formed, the electrical motor of the lifting mechanism left part retarder that is coupling, retarder is connected by gear mesh with main drum, main drum is fixed on the lifting mechanism middle part, twine lifting rope on the main drum, the lifting rope lower end is fixed on the lifting rope fixing seat at cage top, and lower limit travel switch and upper limit position switch are installed on the main drum, main drum one end is installed safety brake, load limiter is installed on the main drum right side, and main drum is connected with loose drum by an external gear wheel, and loose drum is fixed on the lifting mechanism, twine lifting rope on the loose drum, the lifting rope lower end is fixed on the cage top, and described lifting mechanism right part is installed cylinder, twines cable on the cylinder, lifting mechanism top dead sheave, cable is on pulley and draw the control of linking in the cage, illumination equipment, the steel rope fixed bearing is installed at described cage top, and support roller is installed in the side.
The beneficial effect of numerical control turning suspension cage of the present invention is: major and minor reel is installed, main drum is used to hoist, descend cage, loose drum is worked when main drum breaks down, more can guarantee the safety of staff in the cage, load limiter and inhibiting device are installed, are improved the safety performance of whole mechanism; Support roller and balance support arm are installed in the cage side, make cage can remain plumbness at the inclination flue, enlarge range of use.
