Abstract
The present invention relates to a kind of rotary-column type gantry crane revolution anchoring device, it is characterized in that it comprises firm banking (1) and rotating base (2), on the relevant position of described firm banking (1) and rotating base (2), be separately installed with lower guide rod seat (3) and top guide bar seat (4), in described lower guide rod seat (3) and top guide bar seat (4), be provided with guide rod (5), described guide rod (5) is connected with the hydraulic push rod (6) being arranged on firm banking (1), and limit switch (7) is installed on described top guide bar seat (4). The present invention, applicable to using three row's rollers to turn round large bearing gantry crane, has improved the wind resistance security under inoperative condition of rotary-column type gantry crane, has improved the scope of application of gantry crane.
Description
Technical field
The present invention relates to a kind of rotary-column type gantry crane revolution anchoring device. Belong to the technical field of hoisting machinery.
Background technology
Rotary supporting device provides firm supporting for gantry crane rotating part, and the pressure from rotating part and moment are passed to door frame. Large-scale gantry crane, due to from great, is limited to the specification of pivoting support, and large-scale span winch rotary mechanism adopts thrust bearing formula slew gear. Large-scale gantry crane is because front face area is large, during inoperative as strong wind, when the wind idling kinetic moment of crane itself is greater than the stall torque shaft coupling moment of friction of slew gear, gantry crane can passively rotate, and brings potential safety hazard near the equipment of crane.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of rotary-column type gantry crane revolution anchoring device is provided, can effectively improve the security under rotary column gantry crane inoperative condition, expand the scope of application of gantry crane.
The object of the present invention is achieved like this: a kind of rotary-column type gantry crane revolution anchoring device, it comprises firm banking and rotating base, on the relevant position of described firm banking and rotating base, be separately installed with lower guide rod seat and top guide bar seat and be provided with guide rod in described lower guide rod seat and top guide bar seat, described guide rod is connected with the hydraulic push rod being arranged on firm banking, on described top guide bar seat, limit switch is installed.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention, applicable to using three row's rollers to turn round large bearing gantry crane, has improved the wind resistance security under inoperative condition of rotary-column type gantry crane, has improved the scope of application of gantry crane.
