Vehicle CNG gas cylinder loading and unloading and carrying device and loading and unloading method

Abstract

The invention provides a vehicle CNG gas cylinder loading and unloading and carrying device, which mainly comprises three parts, namely a vehicle body, a supporting arm and a loading and unloading hand. The vehicle body is pushed by hands to move forwards and backwards; the supporting arm is designed into a step shape so as to adapt to the narrow space of an automobile trunk and a convex part on an edge of the vehicle; one end of the supporting arm is vertically connected with the vehicle body and can move up and down along the vehicle body, and the other end of the supporting arm mounts and supports the loading and unloading hand; the loading and unloading hand is arranged on a thrust bearing of the supporting arm and is provided with a clamping mechanism so as to grab the gas cylinder; and the loading and unloading hand can rotate on the supporting arm by controlling a rotary operating mechanism. The invention also provides a method for loading and unloading a vehicle CNG gas cylinder. After grabbing the gas cylinder, the loading and unloading hand can take the gas cylinder out of the automobile trunk or put the gas cylinder in the automobile trunk by horizontally advancing and retreating, vertically lifting, rotating and other actions. The vehicle CNG gas cylinder loading and unloading and carrying device has the advantages of solving the problem that the loading, unloading and carrying of the gas cylinder is labor-consuming, avoiding dangers caused by fall-off of the gas cylinder due to careless manual operation, along with better popularization and application prospect.

Description

technical field [0001] The invention relates to a device for loading, unloading and transporting pressure containers, in particular to a safe and labor-saving loading, unloading and transporting device for CNG gas cylinders for vehicles. The invention also relates to a method for loading and unloading CNG gas cylinders for vehicles using the device. Background technique [0002] With the shortage of oil resources, the rise of oil prices, and the improvement of environmental protection requirements for automobiles, more and more automobiles have begun to use compressed natural gas as power fuel. Among them, CNG cylinders (hereinafter referred to as cylinders) used to store compressed natural gas are a kind of Pressure vessels are special equipment, and the state stipulates that such equipment needs to be inspected regularly. When these gas cylinders are inspected, it is necessary to take out the gas cylinders from the trunk of the car earlier, and put it into the trunk of th...

AI Technical Summary

Problems solved by technology

Since the length of the gas cylinder is greater than the transverse width of the outlet end of the rear compartment of the car, and the diameter of the gas cylinder is greater than the longitudinal length of the outlet end of the rear compartment, the movable range of the gas cylinder in the rear compartment is limited and cannot be taken out directly from the rear compartment. Can only be loaded and unloaded after rotating at a certain angle

At present, when inspecting gas cylinders, the loading and unloading mainly depends on manpower. The weight of the gas cylinders is generally 50-60Kg, and the surface of the gas cylinders is smooth, which is not convenient for human hands. Manual loading and unloading is very inconvenient and inefficient.

And when loading and unloading gas cylinders, once the gas cylinder falls to the ground accidentally, it will cause the gas cylinder to be scratched and scrapped, and the dangerous accident of explosion will occur in severe cases.
