Abstract

The invention discloses an electric jack. The electric jack comprises a height adjusting motor, a reduction gearbox, a transmission mechanism, a rhombic bracket, a base at the lower end of the rhombicbracket, a screw rod crossing the rhombic bracket, a supporting top disk at the upper end of the rhombic bracket, a main control circuit and a power supply module. The height adjusting motor, the reduction gearbox, the transmission mechanism and the screw rod are sequentially connected with one another; the main control circuit is separately connected with the height adjusting motor and the powersupply module to control the work of the height adjusting motor and power supply module; the power supply module is separately connected with the main control circuit and the height adjusting motor to provide required power for the main control circuit and the height adjusting motor to work; the power supply module comprises a water-hydrogen machine, and the water-hydrogen machine comprises a methanol-water reforming hydrogen production device, a hydrogen fuel cell and an air pump. The provided electric jack can achieve electric work and improve the convenience and safety of use and can be operated remotely, an operator can keep away from weights which are lifted gradually when operating the electric jack, there is no need to consume physical strength, and the use feeling of a user can beimproved. Meanwhile, the safety of the operator can be improved.

Description

technical field [0001] The invention belongs to the technical field of lifting devices, and relates to a jack, in particular to an electric jack. Background technique [0002] The jack is the simplest lifting equipment with a lifting height of less than 1m. It uses a rigid top lifting piece as a working device, and is a light and small lifting equipment that lifts heavy objects in the stroke through the top bracket or bottom claw. Divided into two kinds of mechanical type and hydraulic type, the jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. Its structure is light and strong, flexible and reliable, and can be carried and operated by one person. [0003] Existing jacks usually need to be manually operated, and the operator needs to be close to the gradually lifted heavy object, and at the same time needs to rotate the rotating rod or press the cross bar to make the jack gradually lift...
