Abstract

The invention relates to a jack with a brake device. The jack with the brake device comprises a base and left and right wallboard parts arranged on the left side and the right side of the base respectively, a lifting arm part and an oil pump device are arranged between the left and right wallboard parts, the rear part of the lifting arm part is movably connected with a piston rod of the oil pump device, a stop part and a pedal part for controlling the stop part are further arranged between the left and right wallboard parts, the stop part comprises a stop arm, the rear end of the stop arm is pivoted to the left and right wallboard parts, a non-slip part is arranged at the front section of the stop arm, the rear portion of the lifting arm part is matched with the non-slip part, the pedal part is pivoted to the left and right wallboard parts, the non-slip part of the stop arm can be separated from a connecting shaft by treading on the pedal part, a reset mechanism is arranged between thestop arm and the left and right wallboard parts, and the reset mechanism applies upward acting force to the stop arm, so that the non-slip part is matched with the connecting shaft. The brake deviceprevents the jack from suddenly falling when a hydraulic system breaks down, thereby playing a role in protecting.

Description

technical field [0001] The invention relates to a jack, in particular to a jack with a braking device. Background technique [0002] Existing horizontal oil hydraulic jacks generally include left and right wallboard parts, and an arm part and an oil pump are arranged between the left and right wallboard parts. The arm part is pivotally connected to the left and right wallboard parts. Rod connection, the other end of the lifting arm part is provided with a top arm, and the bottom of the left and right wall panels is provided with rollers; the existing jack drives the lifting arm part to rotate through the oil pump to realize the lifting of the top arm, and the self-locking of the oil pump is used to maintain the top arm. The arm will not drop when it is stressed, but this kind of jack will suddenly drop when the hydraulic system fails, and there are certain potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a jac...
