Laneway stacker top end braking device and method thereof

Abstract

The invention discloses a laneway stacker top end braking device and a method thereof, and provides a novel electromagnetic clutch control braking device. A snubbing and continuous braking mode in a high-speed running state is achieved through electromagnetic clutch control in the manner of changing different friction modes of a roller at the shaft end of a braking shaft on the surface of a guiderail, and the design purposes of not only improving the braking efficiency, but also reducing the impact force generated to goods shelves when a stacker is started and stopped are achieved. The braking device comprises a rotating arm fixedly installed on an upper cross beam of the stacker and the roller arranged at the far end of the rotating arm; and the rotating arm is arranged on a bracket through a shaft, a braking shaft is arranged at the far end of the rotating arm, the roller is fixedly connected with the shaft end of one side of the braking shaft, and an electromagnetic clutch is connected to the shaft end of the other side of the braking shaft.

Description

technical field [0001] The invention relates to a novel roadway stacker, specifically improving the technical subject of smooth braking when the upper beam of the stacker travels, and belongs to the technical field of logistics storage. Background technique [0002] At present, various types of stackers are usually used in the operation and transportation site of the three-dimensional logistics storage. For the roadway stacker with a large vertical height of the shelf, when the upper beam is braked frequently and at high speed in the roadway, it is required to respond quickly and position accurately. However, due to the high equipment and heavy weight, the running inertia of the equipment is also large, which causes the upper end of the stacker to swing several times during braking before stopping, which seriously affects the efficiency of cargo transmission operations. [0003] as attached figure 1 The existing braking device shown has an overall structure consisting of a...

Problems solved by technology

[0004] The above electromagnetic clutch makes the two magnetic conductors adsorb on both sides of the track through electromagnetic action, but because the thickness of the two spring plates connecting the magnetic conductors is small and the mechanical strength is relatively limited, it is easier to tear when braking. The use reliability and practicability cannot meet the braking requirements of existing large-scale equipment

Moreover, after long-term use, the elasticity of the spring plate weakens, and the return elastic force is difficult to meet the design requirements. The gap between the fixture and the track becomes larger, resulting in a decrease in the braking force and an increase in the braking distance. The corresponding solution can only be to replace the spring plate , the production cost increases accordingly
