Abstract

The invention relates to a novel full-automatic rotation anchoring device of a gantry crane. The novel full-automatic rotation anchoring device comprises a base and an anchoring pin plate, wherein the bottom of the base is connected with a support frame, the right end of the support frame is fixedly connected with a rotation platform of the crane, and a cylinder gantry of the crane is arranged at the lower end of the rotation platform; a vertical transmission screw rod is arranged in the base and is controlled by an anchoring gear motor, and an anchoring reset sensor is arranged above the transmission screw rod; the lower end of the transmission screw rod stretches out of the support frame and is connected with a rotation anchoring pin through a transmission rod, a sleeve is arranged on the outer side of the rotation anchoring pin, the anchoring pin plate with a pin hole is arranged under the rotation anchoring pin and is integrally connected with the cylinder gantry, and an anchoring in-place sensor is arranged at the bottom of the anchoring pin plate; a centering limiting sensor is mounted at the part, on the right side of the sleeve, of the rotation platform, a speed-reduction limiting sensor is arranged in the rotation platform, and a rotation motor with an encoder is arranged on the rotation platform. The full-automatic rotation anchoring device is high in automation degree and easy and convenient to operate and is safe and reliable, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an anchoring device, in particular to a novel fully automatic rotary anchoring device for a portal crane, which can realize manual and automatic rotary anchoring. Background technique [0002] The gantry crane can be divided into two parts: the fixed part and the slewing part. In the non-working state, the slewing part of the gantry crane should be anchored to prevent the slewing part from freely rotating under the action of typhoon and causing safety accidents. Therefore, the slewing anchor device is an essential safety protection device for cranes. Under normal circumstances, it is difficult for the driver alone to complete the positioning operation of the rotary anchor, and one person needs to stand on the circular platform to observe the position of the rotary anchor and notify the operator in the cab to adjust the position of the rotary anchor in time. After aligning the lug plates, enter the machine room and insert the a...
