Lifting and unloading device for cargo box of engineering vehicle

Abstract

The invention discloses an engineering vehicle packing box lifting unloading device, and relates to the technical field of vehicles. The engineering vehicle packing box lifting unloading device comprises two fixing bottom beams, a first connecting plate and a second connecting plate are fixedly connected between the two fixing bottom beams respectively, a first hydraulic rod is fixedly connected to the top of the first connecting plate, a first push rod is rotatably connected to the top of the first hydraulic rod through a movable part, slide blocks are fixedly connected to both ends of the first push rod, and supporting columns are fixedly connected to the sides at the tops of both fixing bottom beams and are provided with groove openings matched with the slide blocks. The engineering vehicle packing box lifting unloading device is provided with a secondary lifting structure, under the condition of not reducing the arm of force, the limit on the vehicle structure is got ridden of, a packing box can be lifted to an enough height, the effect of sharing load bearing of the vehicle body in many angles is achieved, so that an engineering vehicle is balanced in stress, it is guaranteedthat the packing box keeps the center of gravity, the unloading capability of the engineering vehicle is improved, and the safety performance of unloading is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an engineering vehicle container lifting and unloading device. Background technique [0002] Vehicle is the general term for all vehicles. There are many types of vehicles. Due to the standardization and unification, the structure of vehicles is similar. Engineering vehicles are also a kind of vehicles. They are the backbone of a construction project. Because of their appearance, the progress of construction projects is doubled. , greatly reducing the manpower, and the operation of engineering vehicles can not help but shock the power of machines and technology. They are used for carrying, excavating, repairing, and even fighting. [0003] At present, engineering vehicles all use self-unloading unloading, and the unloading is carried out by lifting the hydraulic rod. However, the structure of the existing container lifting and unloading device is relatively simple. Due to the li...
