Lifting device used for horizontal moving type lateral overturning dump truck

Abstract

The invention provides a lifting device used for a horizontal moving type lateral overturning dump truck. The lifting device is formed in the mode that a carriage is fixed to a truck frame through tworeturn safety pins on one side of the carriage and a son-mother safety lock on the other side of the carriage, a sliding groove is formed in a middle crossbeam of the truck frame, multiple transverserolling shafts are embedded in a bottom board of the sliding groove, the carriage slides left and right along the sliding groove, a movable crossbeam is arranged in the sliding groove, the tail end of the movable crossbeam is fixed to the bottom of the carriage, the front end of the movable crossbeam is connected with a lifting oil cylinder through a hinge pin, and the upper end of the lifting oil cylinder penetrates through the bottom of the carriage to be fixed to the upper portion of one carriage wall of the carriage. The lifting device has the beneficial effects that a safety hook at thefront end of the movable crossbeam can limit the carriage and serve as a final force-bearing point when the carriage is laterally overturned, so that plenty of limiting and fixing structures are saved; and a truck body is quite simply fixed through a return safety lock and the son-mother safety lock, so that the truck is remotely controlled by a driver in a cab to be unloaded.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a lifting device for a translational rollover dump truck. Background technique [0002] At present, most of the trucks are backward tipping type. Such cars have several disadvantages. One is that the dumped goods are piled up and it is not easy to arrange them. If the truck is loaded with very heavy goods, such as stones, sand, soil, etc., it is not conducive to unloading, and it will also cause damage to the carriage. [0003] Of course, there are very few trucks that use rollover to unload goods. Most of these trucks are equipped with hydraulic cylinders at the bottom of the compartment. Because the torque between the cylinder and the rollover fulcrum is small, a high-power hydraulic pump is needed to push it. When the object is used, more power is required. [0004] When rolling over and unloading, sometimes the car body rolls over, mainly the carriage. When pushing s...

Problems solved by technology

[0004] When rolling over and unloading, sometimes the car body rolls over, mainly the carriage. When pushing sideways, since the distance of the side push is not limited, it is completely based on the driver's vision. When the carriage rolls over, the car body is unbalanced. of
