Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial equipment, in particular to a roller-transported pallet transporter. Background Art
[0002] With the rapid development of e-commerce and online shopping, and the rapid development of the logistics industry, the handling and transportation of goods in the field of logistics and warehousing will continue to develop in the direction of automation. The transporter can replace manual labor to complete the handling of goods between different conveyor lines or conveyor lines and shelves. The transporter can greatly improve the efficiency of handling and reduce labor costs; the transporters in the prior art are mostly traditional hydraulic transporters, which mainly rely on the hydraulic system to realize the lifting and handling of goods. It is usually composed of hydraulic pumps, hydraulic cylinders, control valves and forks. The pressure generated by the hydraulic pump pushes the piston rod of the hydraulic cylinder to extend and retract, thereby realizing the lifting and lowering of the fork. This hydraulic transporter has the advantages of simple structure, easy operation and low maintenance cost, so it has been widely used in some light load and low frequency handling occasions. However, the maintenance cost of the hydraulic system of the traditional hydraulic transporter is high, and long-term high load is prone to oil leakage. Some sites are oil-free workshops (food factories, pharmaceutical factories, etc.), which are very unfavorable to workshop hygiene and ground cleanliness. In addition, since the hydraulic oil is pumped into the oil pump of the traditional hydraulic transport truck, the lifting and lowering accuracy or forward movement accuracy of the currently commonly used pump body cannot meet the higher requirements. If you want to achieve the relevant requirements, you need to invest a higher cost and the power consumption loss is relatively large.
