Locking device and rotary table provided with same

Abstract

The invention provides a locking device and a rotary table provided with the same and relates to the technical field of locking devices. The locking device comprises a pedestal, a turning plate, lug plates, locking rods and locking plates, wherein the turning plate, the lug plates, the locking rods and the locking plates are rotationally installed on the pedestal; the two lug plates are fixed in parallel to the turning plate; a plurality of locking plates are arranged around the turning plate and on the pedestal; the two lug plates are fixedly connected in parallel; an installation space is formed by virtue of a region between the two lug plates; the two lug plates are correspondingly oppositely provided with through holes; one end of each locking rod is positioned inside the installationspace and is installed inside the corresponding through hole by utilizing a pin shaft; each locking plate is positioned at one side of the corresponding lug plate; the upper surface of each locking plate is provided with a locking groove matched with the other end of the corresponding locking rod; and each lug plate is also provided with a limiting mechanism for limiting swing of the correspondinglocking rod. The locking device provided by the invention achieves the technical effects of being simple, reasonable, safe, reliable and convenient to use.

Description

technical field [0001] The invention relates to the technical field of locking devices, in particular to a locking device and a turntable with the locking device. Background technique [0002] With the continuous growth of the national economy, continuous infrastructure construction and the outbreak of the logistics market, cranes are used more in hoisting, maintenance, emergency rescue and other fields, among which the stop mechanism for locking the crane turntable plays a vital role. Role, the stop mechanism of the turntable currently used is a plug-in lock pin. Since the lock pin is a separate part, it is easy to lose if it is not placed in the designated position after being pulled out, and the construction machinery is used for a long time. Outdoors, due to the erosion of rainwater and other factors, the lock pin is easy to rust and cannot be pulled out, which affects the work and use, and is inconvenient to use.
