Hydraulic vertical conveying device

Abstract

A hydraulic vertical conveying device belongs to the technical field of operating and conveying tools, and comprises an oil cylinder base, an oil cylinder, a pedaled oil pumping mechanism and an oil return valve operation mechanism. The oil cylinder base is provided with an internal oil duct, an oil pump and an oil return valve, and the oil pump is provided with a pump core. The oil cylinder provided with an oil cylinder column is fixed onto the oil cylinder base and communicated with the internal oil duct of the oil cylinder base, a bracket is fixed to an end of the oil cylinder column extending out of a cylinder block of the oil cylinder, and at least a handle is fixed to the outer wall of the upper end of the cylinder block of the oil cylinder. The pedaled oil pumping mechanism consists of a pedal and a pedal lever, the pedal is fixed to one end of the pedal lever, the other end of the pedal lever is hinged onto the oil cylinder base, and a press roller is arranged on the pedal lever. The oil return valve operation mechanism arranged on the outer wall of the oil cylinder is matched with the oil return valve. The hydraulic vertical conveying device has the advantages that the device is simpler in structure, smaller in size, beneficial to manufacture and assembly and inexpensive, and the operating speed of the oil pump can be increased so that the oil cylinder column quickly extends.

Description

technical field [0001] The invention belongs to the technical field of operation conveying tools, 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] In vehicles, especially in the auto repair industry and mechanical equipment repair department, such as the power equipment maintenance department of an enterprise, it usually involves the situation of the conveying device. Taking the auto repair shop in the vehicle repair industry as an example, after the vehicle is lifted by the lifting device or lifted to a certain height by the lifting device, when disassembling the gearbox, exhaust pipe, oil pan or other components, in order to avoid In order to avoid accidents caused by falling and to avoid parts from falling, it is necessary to support it by means of a transport device so that it can be transferred to the repair site for repair after disassem...

Problems solved by technology

[0004]However, the technical solution recommended by CN102225713A above still has the following shortcomings: one is that it is not concise due to the cumbersome structure, for example, in order to avoid setting it on the base (the patent is called a fixed seat The oil cylinder on the ) sways, so it is equipped with an upper fixing plate, and a set of reinforcing struts is arranged between the upper fixing plate and the base. However, such a structure not only increases the volume of the transport device, but also makes the overall structure less Concise, and troublesome to manufacture, install, and cheap

The second is that the action of the pedal oil pump mechanism on the pump core is not stable, which affects the action effect of the pump core, because the pedal of the pedal oil pump mechanism is hinged to the hinged seat of the pedal through the pin shaft, and the hinged seat of the pedal is connected to the filter One end of the rod is connected, and the other end of the filter rod is connected to the pump core. Therefore, there are many transitional links or inflection points between the pedal and the pump core, and the action stroke of stepping on the pedal is large, which affects the pumping speed and is prone to failure.
