The invention relates to a hoisting device and a prefabricated beam hoisting method. The hoisting device includes a gantry frame, a lifting mechanism and a protection device. The gantry frame is set on the ground and the bottom is provided with traveling wheels. The hoisting mechanism includes a motor, a reel and a steel cable. Ring and the second action ring, control ring, block, counterweight and brake lever group, the control ring is provided with an inclined sliding table, the steel cable is pulled out from the reel, wound on the inclined sliding table for a preset number of turns, and then hangs down Suspend heavy objects. When the present invention is in operation, through the cooperation of the control ring, the first action ring and the second action ring, the brake lever group has different yaw directions and yaw angles, and then the brake lever group has different yaw directions and yaw angles, and then the brake lever group has different yaw directions and yaw angles, and then the heavy-load push, heavy-load fall, and light-load There are different braking strategies when hitting the top and falling with a light load, so that the present invention adopts a suitable braking scheme under different conditions to ensure that the parts and cables will not bear huge impacts, and the braking methods are diversified. High performance.
Description
technical field [0001] The invention relates to the field of hoisting and hoisting, in particular to a hoisting device and a prefabricated beam hoisting method. Background technique [0002] At present, in order to facilitate the construction, the beams are generally prefabricated, and then transported to the designated location during construction to complete the installation of the beams. In this process, there is no need to build molds in real time to pour the beams, nor do the templates need to be placed. Demolition makes construction easy. During the installation of prefabricated beams, hoisting and hoisting equipment is required to complete the transfer and lifting of prefabricated beams. [0003] The current control system of the electric hoist realizes the speed control of each node position of start, acceleration, primary deceleration, secondary deceleration, and stop according to the main command control signal. However, when the main control equipment fails, inc...
