The logistics center can be divided into sorting distribution logistics center, self-supporting warehouse/large warehouse logistics center, multi-functional integrated logistics center and other major types. In Japan, the continuous vertical hoist system is standardized and used as the main system of the multi-functional logistics center with its unique flexibility and low maintenance cost. With just getting started, the market has a broad prospect.
Continuous vertical hoist
1. Characteristics of continuous hoist
Continuous vertical hoists do not require the same cumbersome safety checks as escalators. Due to different safety standards, the definition of a vertical hoist appeared in order to distinguish between a simple hoist and a hydraulic scissor hoist. At present, the technical standards and safety standards of continuous vertical hoists are quite perfect. It refers to the use of horizontal and vertical running devices in a multi-story building structure. An automatic non-carrier cargo transportation system that realizes vertical horizontal transportation of goods.
2. How to choose a continuous hoist
When choosing a continuous vertical hoist, you need to understand the criteria for borrowing products. Usually get into the hand from the following aspects.
(1) Structure and process of vertical hoist lifting tower body
At present, the general production enterprises use angle steel, square steel or aluminum alloy to manufacture the lifting tower body of the continuous vertical hoist, mainly because of the simple production process and low investment cost. The design process of the continuous vertical hoist adopts the tower-integrated design structure. The main lifting motor is located at the top of the tower body. The movement coefficient of the tower body determines the stability of the equipment. The calculated strength data of the assembled tower body is the final evaluation of the elevator optimization. key.
(2) Design criteria for the safety inspection system of continuous hoist
Including the following aspects: 1 gravity sensing sensor: detecting the presence of goods and controlling overweight loading; 2 cargo shaped photoelectric sensor: detecting whether the shape of the cargo meets the specified range, whether the operator standardizes the operation; 3 entering the safety monitoring system: preventing personnel from entering the dangerous area ; 4 cargo operation delay, over limit and other safety monitoring systems; 5 driving proximity sensing device, car departure sensing device, running personnel entering dangerous area sensing device; 6 safety fault code automatic display system and troubleshooting system.
(3) Material and processing technology of continuous hoist drum
The main process of the continuous hoist is based on the drum and the chain. Therefore, the quality of the drum and the chain directly determines the advantages of the entire conveying mechanical operating system. The processing technology of the drum and the diameter, thickness, and hardness of the steel are based on the weight and size of the transported product. If the drum is improperly used, the weight of the drum transport cannot match the drum requirement, which will cause the drum to change in a short time. The chain is divided into a main lifting chain and a horizontal driving chain, and its strength is an important basis for evaluating the quality of the continuous hoist.
