Abstract

The invention provides an oil cylinder structure of a hydraulic upright conveyer, and belongs to the technical field of conveying equipment. The cylinder structure of the hydraulic upright conveyer comprises a jacket, a top cap, an oil cylinder, a piston rod and an oil return valve, wherein a gas feeding and discharging screw is arranged in the jacket in a screwed manner; the top cap is fixed with the upper end of the jacket; an oil return passage is formed in the top cap; the oil cylinder is arranged in the jacket; an oil cylinder cavity is communicated with the oil return passage; an oil storage cavity is formed between the outer wall of the oil cylinder and the inner wall of the jacket; the piston rod is arranged in the oil cylinder cavity and is matched with the top cap at the upper end of the piston rod; the oil return valve is arranged on the top cap and corresponds to the oil return passage; and a threaded matching hole of the gas feeding and discharging screw in the jacket is communicated with the oil storage cavity. The oil cylinder structure of the hydraulic upright conveyer is characterized by also comprising an oil return pipe which is arranged in the oil storage cavity; and the upper end of the oil return pipe is connected with the top cap at a position corresponding to the oil return passage. The speed of hydraulic oil flowing to the storage cavity from the oil cylinder cavity can be obviously reduced, the loading piston rod can slowly move towards the oil cylinder cavity, and the hydraulic oil in the oil storage cavity can be prevented from spraying outwards from a matching gap between the gas feeding and discharging screw and the threaded matching hole of the gas feeding and discharging screw.

Description

technical field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to an oil cylinder structure of a hydraulic vertical conveying device. Background technique

[0002] In vehicles, especially in the auto repair industry and mechanical equipment maintenance departments such as power equipment maintenance departments of enterprises, the situation of using transport devices is usually encountered. Take the auto repair industry such as the auto repair factory as an example. After the vehicle is lifted by the lifting device or the lifting device is lifted, when disassembling parts such as gearboxes and exhaust pipes, in order not to fall damage and avoid causing harm to maintenance personnel Therefore, it is necessary to support parts such as the disassembled gearbox, exhaust pipe and oil pan by means of a transport device, and move them to the repair site for repair after disassembly.
