Abstract
The invention relates to a rotation anchoring device of a slewing pillar type gantry crane. The rotation anchoring device is characterized by comprising a fixed base (1) and a rotary base (2), wherein a lower guide rod base (3) and an upper guide rod base (4) are respectively arranged at corresponding positions of the fixed base (1) and the rotary base (2), guide rods (5) are arranged in the lower guide rod base (3) and the upper guide rod base (4) and are connected with a hydraulic push rod (6) arranged on the fixed base (1), and a limit switch (7) is arranged on the upper guide rod base (4). The rotation anchoring device can be suitable for a gantry crane which is incapable of using three lines of roller type rotary large bearings, and has the advantages of improving the wind-resistant safety of the slewing pillar type gantry crane under a non-working condition and enlarging the use range of the gantry crane.
Description
Technical field
The present invention relates to a kind of rotary-column type span winch revolution anchoring device.The technical field that belongs to elevator machinery.
Background technology
Rotary supporting device provides firm supporting for the span winch rotating part, and will pass to door frame from pressure and the moment of rotating part.Large-scale span winch is owing to from great, be subject to the specification of pivoting support, and large-scale span winch swing type mechanism adopts thrust baring formula swing type mechanism.Large-scale span winch is because wind area is big, during inoperative as strong wind, the wind idling kinetic moment of hoisting crane itself is during greater than the stall torque coupler friction moment of swing type mechanism, and span winch namely can passively rotate, give hoisting crane near equipment bring potential safety hazard.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of rotary-column type span winch revolution anchoring device is provided, can effectively improve the safety under the rotary column span winch inoperative condition, expand the range of use of span winch.
The object of the present invention is achieved like this: a kind of rotary-column type span winch revolution anchoring device, it comprises firm banking and rotating base, be separately installed with the lower guide rod seat in the relevant position of described firm banking and rotating base and the top guide bar seat is provided with guide rod in described lower guide rod seat and top guide bar seat, described guide rod is connected with hydraulic push rod on being installed in firm banking, at described top guide bar seat limit switch is installed.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention has improved the wind resistance safety under the inoperative condition of rotary-column type span winch applicable to using three row's rollers to turn round big bearing span winch, has improved the range of use of span winch.
