Rear door locking mechanism used for bagged cement dumper lorry

Abstract

The invention provides a rear door locking mechanism used for a bagged cement dumper lorry. The rear door locking mechanism used for the bagged cement dumper lorry comprises a dumper lorry compartment. The dumper lorry compartment and a rear door are of a split structure. Telescopic devices are arranged on the two outer sides of the dumper lorry compartment correspondingly. The tail ends of the telescopic devices are hinged to the two outer sides of the dumper lorry compartment correspondingly. The piston end of each telescopic device faces the rear door and is integrally connected with the rear door. A lifting device is further arranged on the portion, under each telescopic device, of the dumper lorry compartment, wherein one end of the lifting device is hinged to the side face of the dumper lorry compartment, and the other end of the lifting device is hinged to the side wall of the telescopic device. The telescopic devices and the lifting devices are hydraulic devices. According to the rear door locking mechanism, automatic dumping and orderly stacking of bagged cement are achieved in a traditional dumper lorry lifting dumping mode, the whole mechanism is easy to install, stable in operation, high in reliability and capable of meeting the requirement for orderly stacking after cargoes are dumped.

Description

technical field [0001] The invention relates to a rear door locking mechanism for bagged cement dump trucks, which changes the previous situation that bagged cement relies on manual unloading, and realizes self-unloading and orderly stacking of bagged cement. Background technique [0002] In engineering construction, the transportation, loading and unloading of building materials is very important, which seriously affects the efficiency of engineering construction. Among them, bagged cement has always been unloaded manually in engineering construction, because the traditional self-unloading method cannot stack the bagged cement neatly, which brings difficulties to later rainproof, moisture-proof, and handling, but manual unloading is not only inefficient. High, and labor costs are expensive, this mode of operation needs to be changed urgently. Contents of the invention [0003] In order to improve the unloading efficiency of bagged cement and make it neatly stacked, the p...
