Abstract
The utility model belongs to the technical field of tool application and provides a compression-type static load jack machine; the problems that the size of the output pressure of a traditional static load machine device is hard to control, the traditional static load machine device is easy to overload, and the measuring error is big are solved by the compression-type static load jack machine. During actual work, a handle on the jack is locked through a handle clip; a gear reducer motor is started to lift the jack device; when a crankshaft rotates, a rocker arm is driven to swing, so that compression changes occur on a reset spring fixedly arranged on the handle clip; pressure information is sent to a display screen through a pressure sensor to display measured pressure; after specified pressure is reached, the gear reducer motor is stopped; an oil return valve on the jack is loosened; the movable pressure sensor is pressed down through a track by an air cylinder to press down the part, lifted by the jack, of the piston rod, and the spring is reset. The pressure changes are effectively controlled through the reset spring; various loading pressure sizes can be accurately and conveniently measured; the pressure range is effectively controlled; the service life of the jack is prolonged.
