Abstract

The utility model discloses a hydraulic locking device of a rotating mechanism of a heavy duty crane. The hydraulic locking device comprises a base, a base sleeve, a rotary sleeve, a locking hinge pin, a limiting sensor, a safety pin and a hydraulic cylinder, wherein the base sleeve is installed on the base; the rotating mechanism is positioned on the base sleeve; the rotary sleeve is sleeved inside the rotating mechanism; the locking hinge pin is movably sleeved inside the rotary sleeve; a support rack is installed on the locking hinge pin; the support rack integrally connects the locking hinge pin with the hydraulic cylinder through lifting lug plates arranged on a connecting rod; the limiting sensor is installed on the rotating mechanism; the safety pin is inserted into a connecting hole in the locking hinge pin. By utilizing the hydraulic locking device, when the locking hinge pin works, the rotating mechanism can be locked through the self-weights of a hydraulic system and the locking hinge pin; when the locking hinge pin is in the non-working state, a brake hinge pin is reliably fixed on the rotating mechanism through the hydraulic system and the safety pin, thereby ensuring that the phenomenon of unlocking caused by misoperation in the state is not resulted in.

Description

The hydraulic locking apparatus of heavy duty crane rotating mechanism
Technical field
The utility model relates to latching device, relates in particular to a kind of hydraulic locking apparatus for the heavy duty crane rotating mechanism.
Background technology
Heavy duty crane need to guarantee that whole rotating mechanism is reliably static with respect to pedestal on hand of rotation under static or non-rotating lifting operation state, to prevent rotation platform meet accident when static and the non-rotating lifting operation rotation and initiation Hoisting Security accident.
At present, the heavy duty crane rotating mechanism is based on tribology principle to carry out, and the method for its friction lock is: utilize wedge to be achieved.After rotating mechanism rotates to correct position, by manual operation, wedge is placed on the bottom surface of rotating mechanism and fixedly between the bottom surface, rotating mechanism is stopped the rotation; When hoisting crane need to be rotated again, then wedge is taken out.The hoisting crane position of rotation is locked by artificial placement wedge mode because employing is above-mentioned, except operation is cumbersome, also exist in use potential safety hazard; And due to manually-operated error, can not realize the reliable locking of hoisting crane.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and a kind of hydraulic locking apparatus is provided, its when the work of locking bearing pin, by the deadweight of hydraulic efficiency pressure system and locking bearing pin, just can the locking rotating rotation mechanism; Under locking bearing pin off position, by hydraulic efficiency pressure system and safety pin, braking pin shaft is fixed on rotating mechanism reliably, guarantee not occur the release phenomenon that causes because of maloperation under this state.
The purpose of this utility model is realized by following technical scheme:
A kind of hydraulic locking apparatus of heavy duty crane rotating mechanism is characterized in that: comprising: pedestal, base socket sleeve, turnbarrel, locking bearing pin, limit sensors, safety pin, hydraulic actuating cylinder, and wherein, base socket sleeve is arranged on pedestal; Rotating mechanism is positioned on base socket sleeve, and suit one turnbarrel in rotating mechanism, movable set one locking bearing pin, be equipped with a bracing frame on the locking bearing pin in this turnbarrel, and this bracing frame is by connecting rod and be located at that shackle plate on connecting rod will be locked bearing pin and hydraulic actuating cylinder connects as one; Limit sensors is arranged on rotating mechanism, and safety pin inserts the connecting bore that is positioned on the locking bearing pin.
Described pedestal is: cylinder-like structure, this pedestal coordinates with the locking bearing pin, and is arranged on fixed sturcture.
Support frame as described above is door type tower structure.
One guide plate is installed on described safety pin, and this guide plate is trumpet type.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, its when the work of locking bearing pin, by the deadweight of hydraulic efficiency pressure system and locking bearing pin, just can the locking rotating rotation mechanism; Under locking bearing pin off position, by hydraulic efficiency pressure system and safety pin, braking pin shaft is fixed on rotating mechanism reliably, guarantee not occur the release phenomenon that causes because of maloperation under this state.
