Quick-lift-type vertical jack with double pump structure

Abstract

The invention relates to a quick-lift-type vertical jack with a double pump structure. The quick-lift-type vertical jack comprises a fixed base and a vertical jack body. Oil pump connecting blocks arefixed to the left and right sides of the fixed base, fixed supporting rods are fixed in front, a connecting inserting tube is arranged above a connecting positioning pin, the vertical jack body is located above the fixed base, and a foot supporting mechanism is installed outside the vertical jack body. The quick-lift-type vertical jack has the beneficial effects that through simultaneous workingof two pressurized oil pumps, the lifting speed of equipment is increased, the working efficiency of the equipment is improved, three supporting feet can be expanded to provide auxiliary support through the foot supporting mechanism so as to improve the stability of the equipment, the length of a pressure rod is adjusted by a pressure mechanism, so that the equipment can work in a deeper place, anarc-shaped connection top block can prevent the equipment from slipping at a jacking point, and a safety bracket is used to support so as to protect the equipment and to prevent the equipment from being damaged and heavy objects from falling and hurting people.

Description

technical field [0001] The invention relates to the technical field of vertical jacks, in particular to a fast-rising vertical jack with a double-pump structure. Background technique [0002] The jack is a kind of light and small lifting equipment that uses a rigid lifting piece as a working device, and lifts heavy objects within the stroke through the top bracket or bottom claw. The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and maintenance. For other lifting and supporting tasks, its structure is light and firm, flexible and reliable, and can be carried and operated by one person. Vertical jack is a kind of jack, which is mainly used in various mechanical processing industries, maintenance industries, and transportation industries. [0003] The existing vertical jack works in the form of a single pump, which causes the equipment to rise too slowly, which affects the working efficiency of the equipment. The bottom of the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a fast-rising vertical jack with a double-pump structure to solve the problem that the existing vertical jack proposed in the background technology uses a single pump to work, which causes the equipment to rise too slowly and affects the safety of the equipment. Work efficiency, the bottom of the existing vertical jack is not stable enough, it is easy to cause the equipment to tilt, so that the jacked objects fall, the existing vertical jack supporting the pressure bar has a fixed length, when the equipment needs to work in a deep place It is not convenient for the staff to apply pressure. The top of the existing vertical jack is a sheet-shaped supporting arc that is easy to slip. If the existing vertical jack is damaged during work, the lifted object will fall directly, causing danger to the staff.
