Upper-mounted rear hoist mechanism of a dump truck

Abstract

The invention discloses an upper-mounted rear hoist mechanism of a dump truck, the structure comprising an articulated shaft, boom plate, vertical plate, side panel, storage compartment, Warning devices, angle guides, A left-right adjust device is arranged on that rear door panel and the angle guide device, fixed driving device, Pull trigger, forced moving device, mechanical linkage, transmissionconnection device, fixed balancing device, Enclosure, beneficial effect: with the addition of an angle guide, which can be combined with the upper rear opening and closing mechanism to drive the device to run when the rear door is opened integrally, When the vehicle is unloaded, the cargo will slide down from above the guide device, the cargo can be unloaded steadily, a large amount of cargo can be prevented from being crushed and smashed during the unloading, and the cargo can be evenly distributed through the device.

Description

technical field [0001] The invention relates to an upper-mounted rear opening and closing mechanism of a dump truck, which belongs to the field of dump trucks. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. It is composed of a car chassis, a hydraulic lifting mechanism, a cargo compartment and a power take-off device. There are two types of tipping and lateral tipping. The movement of the piston rod is controlled by the operating system. The rearward tipping is more common, and the piston rod is pushed to make the cabin tip over. A few two-way tipping is a kind of top-mounted rear opening and closing mechanism for dump trucks in common technology at present. The rear door is opened and closed through the lower rear opening and closing mechanism and the upper hinge seat, and is driven by the hydraulic jacking system of the dump truck to make the cabin tilt backward. The...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a top-mounted rear opening and closing mechanism for dump trucks, so as to solve the problem that the rear door of a dump truck with a top-mounted rear opening and closing mechanism commonly used in the current technology is opened and closed through its bottom-mounted rear opening and closing mechanism. mechanism and the upper hinge seat to open and close the rear door, and the hydraulic jacking system that comes with the dump truck is driven to make the compartment tip over backwards. There is still a certain distance between the dump truck and the ground when it is unloading. When unloading, a large number of goods will swarm down, it is inevitable that the goods will be smashed and piled up together, and manual transportation is required. One more process will waste a lot of time.
