The invention discloses a safety lock pin device for workpiece overturning and a workpiece overturning system. The safety lock pin device comprises a safety pin, a triangular lock plate, an elastic positioning pin and a lock. The safety pin is used for being inserted into a base and an overturning workpiece and locking the angle of the overturning workpiece relative to the base; the first corner end of the triangular lock plate is connected to the axial surface of the safety pin through a fastener, and the triangular lock plate can rotate around the fastener; the elastic positioning pin is mounted at the second corner end of the triangular lock plate and is used for being inserted into two positioning counter bores in different positions on the axial surface of the safety pin to limit the position of the triangular lock plate, so that the safety pin is pulled out of the overturning workpiece or is prevented from being pulled out; and the lock is installed at the third corner end of the triangular lock plate and used for limiting rotation of the triangular lock plate, and the triangular lock plate is rotated by unlocking the lock and pulling out the elastic positioning pin. The safety lock pin device has the advantages of being simple in structure, convenient to operate and high in safety, mounting, locking and unlocking of the safety pin can be achieved, and safety and convenience are greatly improved.
Description
technical field [0001] The invention relates to a safety lock pin device for turning workpieces, and belongs to the technical field of mechanical mechanisms. Background technique [0002] Mining dump trucks are generally dump vehicles with a load capacity of more than 30 tons, with large load capacity and large volume. During vehicle maintenance, it is necessary to turn over the cargo compartment, cab, engine compartment and other components first. In order to ensure the safety of the maintenance personnel, these parts need to be locked after turning over to prevent system failure or human factors from landing and crowding. Press down on the maintenance guys. [0003] At present, there are many related technologies, using means such as support rod support, cable limit, and self-locking check valve inside the hydraulic system, etc., to play the role of limit, but the operation is more complicated, and external tools are required for installation or removal. In addition, whe...
