Abstract
The utility model relates to a rotating anchoring device for a rotary-column gantry crane. The rotating anchoring device is characterized by comprising fixed bases (1) and a rotating base (2), wherein the corresponding parts of the fixed bases (1) and the rotating base (2) are respectively provided with a lower guide rod seat (3) and upper guide rod seats (4), guide rods (5) are arranged inside the lower guide rod seat (3) and the upper guide rod seats (4) and are connected with hydraulic push rods (6) which are installed on the fixed bases (1), and a limiting switch (7) is installed on each upper guide rod seat (4). The rotating anchoring device is applicable to the gantry crane which cannot utilize a three-row rotary-column rotating large bearing, the wind-resisting safety of the rotary-column gantry crane under a non-working condition can be improved, and the application range of the gantry crane is enlarged.
Description
Technical field
The utility model 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, due to from great, is limited to the specification of pivoting support, and large-scale span winch rotary mechanism adopts thrust baring formula swing type mechanism.Large-scale span winch is because wind area is large, during inoperative as strong wind, when the wind idling kinetic moment of hoisting crane itself is greater than the stall torque coupler friction moment of swing type mechanism, span winch can passively rotate, and brings potential safety hazard near the equipment of hoisting crane.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of rotary-column type span winch revolution anchoring device is provided, and can effectively improve the safety under rotary column span winch inoperative condition, expands the range of use of span winch.
The purpose of this utility model is achieved in that a kind of rotary-column type span winch revolution anchoring device, it comprises firm banking and rotating base, be separately installed with lower guide rod seat and top guide bar seat and be provided with guide rod on the relevant position of described firm banking and rotating base in described lower guide rod seat and top guide bar seat, described guide rod is connected with the hydraulic push rod on being arranged on firm banking, on described top guide bar seat, limit switch is installed.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, applicable to using three row's rollers to turn round large bearing span winch, has improved the wind resistance safety under the inoperative condition of rotary-column type span winch, has improved the range of use of span winch.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the AA cutaway view of Fig. 1.
Wherein:
Firm banking 1
Rotating base 2
Lower guide rod seat 3
Top guide bar seat 4
Hydraulic push rod 6
The specific embodiment
Referring to Fig. 1-Fig. 2, the utility model relates to a kind of rotary-column type span winch revolution anchoring device, comprise firm banking 1 and rotating base 2, rotary column welding under described rotating base 2 and span winch, described firm banking 1 and the welding of span winch door frame, described rotating base 2 is positioned at the top of firm banking 1, be separately installed with lower guide rod seat 3 and top guide bar seat 4 on the relevant position of described firm banking 1 and rotating base 2, be provided with guide rod 5 in described lower guide rod seat 3 and top guide bar seat 4, described guide rod 5 is connected with the hydraulic push rod 6 on being arranged on firm banking 1, described guide rod 5 can be in top guide bar seat 4 and the interior movement of lower guide rod seat 3, on described top guide bar seat 4, limit switch 7 is installed, when rotary-column type span winch inoperative, first by crane arm support towards being rotated in place, hydraulic push rod 6 promotes guide rod 5 and enters top guide bar seat 4 along lower guide rod seat 3, touch the rear execution of limit switch 7.
