Horizontal-push type self-discharging vehicle

Abstract

The invention relates to a horizontal-push self-dumping truck, which is provided with a self-dumping machine and a self-dumping hydraulic system. The self-dumping machine comprises a carriage, a pushing carriage and a pushing part, wherein the pushing carriage is positioned in the carriage and is shorter than the carriage; and the pushing part is positioned in the pushing carriage and is shorter than the pushing carriage. The self-dumping hydraulic system comprises a left hydraulic cylinder, a right hydraulic cylinder, a middle hydraulic cylinder, a hydraulic pump, a hydraulic oil tank and related valves, wherein the left hydraulic cylinder and the right hydraulic cylinder are arranged between the carriage and the pushing carriage parallelly; and the middle hydraulic cylinder is arranged between the pushing carriage and the pushing part parallel to the left hydraulic cylinder and the right hydraulic cylinder. The left hydraulic cylinder and the right hydraulic cylinder are fixed on a bottom board of the carriage, piston rods of the left and right hydraulic cylinders are connected to the back end of the pushing carriage, and the pushing carriage is driven by the left and the right hydraulic cylinders to slide on the bottom board of the carriage. The middle hydraulic cylinder is fixed on the front end of the pushing carriage, a piston rod is connected to the back end of the pushing part, and the pushing part is driven by the middle hydraulic cylinder to slide on a bottom board of the pushing carriage. The self-dumping truck adopts the horizontal-push self-dumping without moving the carriage, does not have requirements on a space above a vehicle or a space behind the vehicle. Accordingly, the self-dumping truck can be used in sites with narrow spaces, such as a laneway of a coal mine, and solves the problem of transporting materials of thin coal layers of the coal mine.

Description

technical field [0001] The invention relates to a flat push type dump truck. Background technique [0002] Lifting dump trucks are the most common type of dump truck. Under the action of the lifting hydraulic cylinder, the front end of the lift dump truck compartment is lifted, so that the compartment forms an angle with the chassis, and the cargo is poured out from the rear opening of the compartment. Form dump. China's authorized announcement number is CN1212246C. The invention patent specification discloses a push-back dump truck. A pair of carriage horizontal push hydraulic cylinders are installed at the front of the carriage. When it stretches out, it will push the carriage to move backward three minutes along the slide rail One is to make the carriage leave the fixed floor at the rear, and the rear third of the carriage is suspended (the rear third of the carriage has no floor), and part of the cargo is discharged from the suspension, and then the second stage of the ...

AI Technical Summary

Problems solved by technology

The above two types of dump trucks rely on the movement of the carriage when unloading, so the site is required to have a certain space above or behind the truck, so it is not suitable for use in narrow spaces, such as underground coal mines
