Stacking machine object bearing platform overspeed protection device

Abstract

The invention discloses a stacking machine object bearing platform overspeed protection device. The stacking machine object bearing platform overspeed protection device is installed on an object bearing platform of a stacking machine. The stacking machine object bearing platform can be pulled by a pulling rope to move up and down along a preset guide track on a stand column of the stacking machine. The stacking machine object bearing platform overspeed protection device comprises safety tongs and a safety tong triggering mechanism. The safety tong triggering mechanism comprises a pulley pulling portion and a lever triggering portion. The pulley pulling portion and the lever triggering portion are movably connected. The pulley pulling portion is connected with the pulling rope, the lever triggering portion is connected with a safety rope, and the safety rope is connected with a speed limiting meter of the object bearing platform. A spring mechanism is installed on the pulley pulling portion, and the balance is formed among the pulling force of the pulling rope, the elasticity of the spring mechanism and the safety rope tension conducted by the lever triggering portion. By means of the mode, the stacking machine object bearing platform overspeed protection device can achieve the immediate response when the pulling rope is broken and automatic speed limiting adjustment when the overspeed exists, and is high in response speed and high in reliability.

Description

technical field [0001] The invention relates to the field of warehousing automation, in particular to an overspeed protection device for a stacker loading platform. Background technique [0002] Since the operating efficiency and automation technology level of automated three-dimensional warehouses can greatly improve the logistics efficiency of enterprises, and the basic technology of three-dimensional warehouses is becoming more and more mature, more and more enterprises have begun to adopt automated three-dimensional warehouses. Many enterprises not only build medium and large three-dimensional warehouses, but also build many small and medium-sized automated three-dimensional warehouses according to needs. With the increase of automated three-dimensional warehouses, the application of stackers is becoming more and more extensive. When the stacker is working, it realizes the transfer of high-level goods in the three-dimensional warehouse by controlling the loading platform...

AI Technical Summary

Problems solved by technology

When the stacker is working, it realizes the transfer of high-level goods in the three-dimensional warehouse by controlling the loading platform on the stacker to move up and down along the column of the stacker. Because the loading platform needs to move up and down frequently, sometimes it will Or equipment failure causes the stage to go out of control, and when the stage falls too fast, it will cause a large safety hazard. For this problem, there have been some overspeed protection devices on the market, but the existing overspeed protection devices are not suitable for this kind of overspeed protection device. The phenomenon of over-speed falling in a short distance is often not sensitive enough, often the stage has fallen to the ground and the over-speed protection device has not been activated in time
