Lifting device for loading and unloading equipment for electric overhaul vehicle

Abstract

The invention discloses a lifting device for loading and unloading equipment for an electric overhaul vehicle. The device comprises a vehicle tail hopper, a lifting base, a lifting frame assembly, a driving mechanism and a suspension mechanism, wherein the lifting base is fixedly arranged at one side, close to a vehicle head, in the vehicle tail hopper; the top of the lifting base is fixedly provided with a first hydraulic cylinder; the output end of the first hydraulic cylinder is fixedly provided with a hydraulic rod; one end, far away from the first hydraulic cylinder, of the hydraulic rodis fixedly arranged with a second hydraulic cylinder in an L shape, and the output end of the second hydraulic cylinder is fixedly arranged with a lifting arm through the hydraulic rod. According to the device, the lifting assembly and the suspension mechanism are arranged and enable clamping lifting and suspension lifting modes of the lifting device, so that applicable lifting range is expanded;a vacuum chuck is capable of performing vacuum adsorption on a clamped article, so that the clamping and lifting stability can be effectively improved; the electric overhaul vehicle is subjected to loading and unloading without manual carrying; in addition, the loading and unloading are convenient and time and force saving, so that the working intensity of electric overhaul workers can be effectively reduced.

Description

technical field [0001] The invention relates to the field of loading, unloading and lifting, in particular to a lifting device for loading and unloading equipment for electric maintenance vehicles. Background technique [0002] Hoisting refers to the general term for the installation and positioning of equipment by a crane or a lifting mechanism. During the maintenance or maintenance process, various hoisting tools are used to lift equipment, workpieces, appliances, materials, etc., so that their positions change. It plays a very important role in the power system, and large electrical equipment or power distribution equipment needs to be lifted by lifting devices. [0003] However, the existing lifting device adopts one of the lifting methods of hanging lifting or clamping lifting, and the lifting method is single. For the diversity of electric equipment, clamping lifting is not conducive to the lifting and loading and unloading of linear equipment, and suspension lifting i...

Problems solved by technology

[0003] However, the existing lifting device adopts one of the lifting methods of hanging lifting or clamping lifting, and the lifting method is single. For the diversity of electric equipment, clamping lifting is not conducive to the lifting and loading and unloading of linear equipment, and suspension lifting is for large-scale The power equipment is inconvenient to hang, and the phenomenon of sliding between the lifting splint and the object to be lifted is easy to occur, which not only affects the normal lifting operation, but also has hidden dangers to the personal safety of the operator and the safety of the object to be lifted, and the practicability is poor
