Description

Technical Field

[0001] The invention relates to the field of lifting conveyors, and in particular to a mobile electric hydraulic lifting conveyor. Background Art

[0002] Hydraulic conveyors are widely used in automobile repair, automobile maintenance and other industries. Hydraulic conveyors are mainly used for high-position installation and disassembly of automobile gearboxes, engines, transmissions, etc. They are indispensable lifting and transporting tools in automobile repair and maintenance.

[0003] For example, the patent document with patent number 201720521613.9 discloses a hydraulic conveyor, including a chassis and a bracket, with supporting feet fixed on both sides of the chassis, casters arranged on the ends of the supporting feet, an oil cylinder arranged above the chassis, an opening arranged on the side of the oil cylinder, a refueling pipe connected to the opening, the refueling pipe including a tube body and an oil inlet terminal and an oil outlet terminal arranged at both ends of the tube body, the oil outlet terminal being welded to the opening of the oil cylinder, the oil inlet terminal and the oil pipe being detachably connected, the oil inlet terminal including a torsion portion and a docking portion connected to each other, an annular sealing ring being arranged at the connection between the torsion portion and the docking portion, a filter assembly being arranged in the docking portion, and a filter mesh being arranged in the oil outlet terminal.

[0004] The above technical solution realizes filtering of liquid oil by respectively setting oil inlet terminals and oil outlet terminals at both ends of the oil pipe, and placing filter components and filter meshes in the oil inlet terminals and the oil outlet terminals respectively. Moreover, the liquid oil is filtered twice to ensure the cleanliness of the liquid oil entering the oil cylinder, thereby ensuring the stability of the output force of the oil cylinder.
