Hydraulic lifting device of loading and unloading trolley

Abstract

The invention discloses a hydraulic lifting device of a loading and unloading trolley. The hydraulic lifting device of the loading and unloading trolley includes a trolley hopper. The lower portion ofthe trolley hopper is provided with a steel pipe sliding rail through a bearing pad. One end of the steel pipe sliding rail is fixedly connected with a shaft pipe. The steel pipe sliding rail is connected with a round shaft through the shaft pipe at one end. The lower portion of the round shaft is fixedly provided with a supporting pipe and the round shaft is fixed to the upper end of the supporting pipe. The lower end of the supporting pipe is fixedly connected with a trolley plate. The upper side of the trolley plate is provided with a spring column and the lower portion of the spring column is fixed to the upper wall of the trolley plate in clamped and connecting modes. According to the hydraulic lifting device of the loading and unloading trolley, a principle of hydraulic lifting is used to construct the loading and unloading trolley, the loading and unloading trolley is internally provided with the steel pipe sliding rail and a sliding block column through the hydraulic lifting device; in the using process, the hydraulic device drives the sliding block column to rise; and one end of the trolley hopper rises under the effects of the sliding block column and the steel pipe sliding rail. According to the hydraulic lifting device of the loading and unloading trolley, one end of the trolley hopper can rise and lower automatically; the process of loading and unloading is made to be flexible and convenient; and maneuverability and flexibility of the loading and unloading trolley are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a hydraulic lifting device for loading and unloading vehicles. Background technique [0002] At present, the loading and unloading truck is the logistics handling equipment that plays the role of moving goods. When the loading and unloading truck is used at the handling station, it holds up the goods it carries, and the hydraulic system is driven by manpower to realize the lifting and lowering of the pallet goods, and the manpower is pulled to complete the handling operation. It is the easiest, most effective and most common loading and unloading and handling tool in the pallet transport tool of the handling station. In real life, there are many applications of loading and unloading trucks, most of which are used in commercial logistics, generally used for truck drivers to pull goods or clean up municipal garbage, and have been widely used in life, greatly improving...

AI Technical Summary

Problems solved by technology

Even so, there are still certain deficiencies and defects in the equipment on the market now. The field of loading and unloading trucks with hydraulic lifting devices is relatively lacking in the market now, which makes the loading and unloading trucks inconvenient in use and cannot save oil. Secondly, the use effect is not good, so that the loading and unloading truck cannot achieve the purpose of convenience in the process of using the loaded goods and unloading the goods, which brings certain troubles to the workers' operation and wastes material resources and manpower costs.
