Truck automatic cover sheet device

Abstract

The invention relates to the technical field of carriage shield assembly parts, in particular relate to a device for automatically covering tarpaulin of a truck. According to the device disclosed by the invention, a stepping motor is adopted, so that the device can work more accurately and effectively; a control device and a remote control are adopted, so that people can remote control the work of the device, the work can be more efficient, and manpower and material resources can be saved; an external rotor motor is adopted, so that the structure of the device can be more simple, and assembly and maintenance are more convenient and efficient; a winding drum is adopted, so that device coverage and tarpaulin folding can be more efficient, and the manpower and the material resources can be saved; an expansion bracket is adopted, so that the mass of the device can be lighted, and the device structure can be more simple, lighter and convenient; a guide rail pulley is adopted, so that the expansion and the contraction of the expansion bracket can be more rapid, and the labor and the time can be saved; an inner shears-fork plate and an outer shears-fork plate are adopted, so that the structure of the expansion bracket can be more simple, lighter and convenient.

Description

technical field [0001] The invention relates to the technical field of assembly components of a protective cover for a carriage, in particular to an automatic cover sheet device for a truck. Background technique [0002] When the cargo compartment is loaded with powdered goods (such as bulk cement, lime, stone powder, etc.) or the cargo has relatively large dust (such as construction waste, etc.), or to avoid the sun and rain, the top of the compartment should always be covered. Carriages include various automobile carriages, train carriages, etc. Most car body coverings require manual work to be done. Because the general compartment is very high and full of goods, especially powdery goods, soil, sand and stones are easy to be higher than the top surface of the compartment, forming mountain-shaped materials, it is necessary to climb to the top of the compartment to cover the tarpaulin, the work intensity is high, difficult and has Greater danger.
