Hydraulic vertical-type conveying device

Abstract

The invention discloses a hydraulic vertical-type conveying device and belongs to the technical field of conveying apparatuses. The conveying device comprises a lower fixing seat, an oil cylinder, a group of reinforcing struts, a thread-type oil pumping mechanism and a pressure oil releasing mechanism, and is characterized in that the oil cylinder comprises an oil cylinder base, a pump core, a pump cover, a pump core spring, a cylinder sleeve, an inner cylinder, a cylinder cover and a piston rod; the oil cylinder base is arranged on the lower fixing seat and is provided with an oil inlet duct, an oil return duct, a ball valve, a high-pressure oil duct, a high-pressure oil cavity, a high-pressure oil discharging duct and a high-pressure oil on-off valve; and the end part, extending out the cylinder cover, of the piston rod is fixedly provided with a bracket, a thread-type oil-pumping mechanism is matched with the pump core, the pressure releasing mechanism is arranged on the cylinder cover, and an upper fixing seat is sleeved on the cylinder cover. The hydraulic vertical-type conveying device has the advantages of rational integral structure, ideal work stability, convenience in operation and labor conservation.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment, and in particular relates to a hydraulic vertical conveying device, which is applied to industries such as vehicle and mechanical equipment maintenance. Background technique [0002] The use of conveying devices is often involved in the vehicle repair industry, especially in the vehicle repair industry, and in machinery repair departments such as power plant maintenance departments of enterprises. Taking the automobile maintenance industry such as the auto repair factory as an example, after the vehicle is lifted by the lifting device or lifted by the lifting device, when disassembling parts such as gearboxes and exhaust pipes, in order not to fall damage and avoid posing a threat to the safety of maintenance personnel Therefore, it is necessary to support the disassembled gearbox, exhaust pipe, oil pan and other components by means of a transport device, and move them to the repair s...

Problems solved by technology

However, this patent scheme does not provide corresponding technical inspiration for the oil cylinder structure as the core component, so if the oil cylinder structure of the known vertical jack is purely applied, a series of technical problems will arise, such as the position of the oil return valve as the pressure release mechanism 1. The structure of the oil return valve itself, and the cooperation of the tread plate and the pump core of the oil cylinder, etc. all need to be reasonably designed.
