Abstract

The invention discloses a mechanical speed locking device and locking method for bridges, and the mechanical speed locking device belongs to an energy consumption type force transfer device. The mechanical speed locking device includes an upper anchorage plate assembly, a transmission case, a rack connection rod, a transmission gear, a bearing shaft, a ratchet wheel, pawls, pendulums, a rolling shaft, first rotation shafts, second rotation shafts, balance springs, a lower base, and a lower anchorage plate assembly; the upper anchorage plate assembly is fixedly connected to the transmission case; one ends of the balance springs are fixed on the transmission case, the other ends of the balance springs are fixed on the pawls; the pawls are arranged on the transmission case through the second rotation shafts; the pendulums swing around the first rotation shafts to drive the pawls to rotate around the second rotation shafts; the rack connection rod is arranged on the rolling shaft, and contact and is engaged with the transmission gear; the rack connection rod is hinged to the lower base; and the lower base is fixed on the lower anchorage plate assembly. The mechanical speed locking device can lock the bridge and piers when the bridge does deformation motion due to factors such as the temperature and the speed exceeds a control value.

Description

technical field [0001] The present invention relates to a non-energy-consuming force transmission device and its use method, in particular to a device used in bridge construction that can effectively lock mass blocks together through dynamic connecting rods when earthquakes and wind vibrations occur. A mechanical speed locking device and a locking method for a bridge. Background technique [0002] As a non-energy-consuming force transmission device, the speed locking device is required to move freely under the slow deformation of the bridge due to factors such as temperature. When the speed exceeds its control value, it will lock the movement like a seat belt in a car. Hold, play the role of dispersing and transferring force. At present, the generally used speed locking device is developed based on the technology of liquid viscous damping device, and uses viscous material as its filling medium. However, as a hydraulic device, its working life is limited by the cycle life of...
