Proceeding self-locking device

Abstract

A proceeding self-locking device belongs to the technical field of accessories of mobile machinery. Four wheels are fixedly connected onto four corners of the bottom surface of a machine body base plate through a support respectively, a hinged supporting seat I is fixedly connected onto the front portion of the bottom surface of the machine body base plate, two steel wire soft rope limit seats are respectively fixedly connected onto the front end and the rear end of the top surface of the machine body base plate, the front end and the rear end of a steel wire soft rope are fixedly connected a connecting rod II and a control rod respectively, the left end of a main shaft I is fixedly connected with the wheel axle of the left rear wheel, the right end of a main shaft II is fixedly connected with the wheel axle of the front right wheel, two ends of a connecting piece I are movably connected with a connecting rod I and the main haft I, a connecting piece II is movably connected with the connecting rod II and the main shaft II, two ends of the long hinge pin I of the connecting rod I penetrate a limit hole I and a limit hole II respectively, two ends of the long hinge pin II of the connecting rod II penetrate a limit hole III and a limit hole IV respectively, the hole VI of the control rod is movably connected with the hinged supporting seat I, and the control rod and the connecting rod I are movably connected. The proceeding self-locking device can achieve heavy load and avoid the lateral movement, rollover and toppling over of a device on an inclined plane, is simple in structure and easy to operate, and can avoid operational errors more easily.

Description

technical field [0001] The invention belongs to the technical field of walking machinery accessories, and in particular relates to a self-locking device for short-distance transportation. Background technique [0002] For a long time, a variety of mechanical equipment, hydraulic equipment, and electrical equipment often need to be transported over short distances. The traditional self-locking method has always used hydraulic, pneumatic or connecting rods to control the position of the brake pads, so that the brake pads and The moving parts are in contact to generate static friction, so as to realize the self-locking of the traveling equipment. The equipment is equipped with a handle, and the handle is connected with a self-locking device. It is necessary to press the handle to make the transport equipment in a movable state. The traditional anti-falling method uses an anti-falling rod, but the anti-falling rod is not only expensive but also unreliable, and it is very easy to...
