Rocker arm type linkage turnover device of muck truck cover plate

Abstract

The invention provides a rocker arm type linkage turnover device of a muck truck cover plate, and relates to the field of mechanical devices. The rocker arm type linkage turnover device comprises a front cover. A rear cover is installed at one end of the front cover in a rotating manner through a hinge. Rocker arms are symmetrically arranged on the left side and the right side of the front cover along the middle axis of the front cover. Each rocker arm comprises a front rocker arm close to the hinge. A rear rocker arm is arranged on the side, away from the hinge, of the corresponding front rocker arm. A turnover mechanism is arranged on each front rocker arm and comprises a turnover plate. A connection plate is installed on each turnover plate in a rotating manner. A fixed plate is installed at the tail end of each connection plate in a rotating manner. According to the rocker arm type linkage turnover device, the front cover and the rear cover are arranged and connected through the hinge, and therefore after the muck truck rear cover plate overturns anticlockwise by a certain angle, no space of a compartment body is occupied; each turnover mechanism is of a four-bar linkage structure, the turnover plates and the fixed plates are connected through connecting rods, and therefore the freedom requirement in the rear cover movement process is met; and the whole rocker arm type linkage turnover device is high in loading efficiency, good in overload prevention and leakage prevention effect, large in loading volume and high in practicability.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a linkage overturning device for a rocker arm type muck truck cover. Background technique [0002] Muck trucks refer to trucks mainly used to transport construction materials such as sand and construction waste. With the continuous development of cities, the speed of urban construction is accelerating and the scale is increasing, so the demand for muck trucks is also increasing. . During the transportation of muck trucks, there are phenomena such as raising dust along the way, leaking and throwing, and the urban environment is polluted and destroyed again. Therefore, various cities have begun to implement the control and transformation of muck trucks, and vigorously promote environmental protection muck trucks. [0003] At present, the traffic safety and environmental pollution problems of muck trucks are becoming more and more prominent. Traditional muck trucks are overloade...

AI Technical Summary

Problems solved by technology

However, when the cover plate is opened, due to structural factors, the cover plate needs to protrude forward for a distance of 2-3 meters, and the tail end of the cover plate hangs at the front of the cargo compartment, occupying the loading space at the front of the cargo compartment, making the muck truck Cannot make full use of the box space, reducing the effective volume of the box
