Embodiment Construction

[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] Combine below figure 2 with image 3 , the preferred embodiment of the present invention is described in further detail,

[0024] Such as figure 2 As shown, the active inflatable sealing control system of this preferred embodiment is provided with a cargo box on the chassis of the vehicle, and a cargo unloading door is installed on the cargo box, and the inflatable sealing ring 10 is installed between the cargo unloading door and the cargo box. The unloading door is generally installed at the end of the cargo box, but some dump trucks install the unloading door on the left or right side of the cargo box. Generally, dump trucks include a lifting cylinder. Both ends of the lifting cyli...

Abstract

The invention discloses an active inflatable sealing control system. A carriage is mounted on a vehicle chassis, a dumping door is mounted in the carriage, and an inflatable seal ring is disposed between the dumping door and the carriage. The active inflatable sealing control system comprises a controller, a pressure sensor and an inflatable electromagnetic valve. The pressure sensor feeds detected inner pressure signals of the inflatable seal ring back to the controller, and when the inner pressure of the inflatable seal ring is lower than a preset threshold value, the controller controls the inflatable electromagnetic valve to inflate the inflatable seal ring. The invention further provides a dumper. Active compensation can be achieved through the inflatable seal ring under the condition that the gap between the dumping door and the carriage changes due to mechanism abrasion, deformation and the like, so that the pressure of the inflatable seal ring is kept constant.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an active inflation and sealing control system and a dump truck. Background technique [0002] At present, there is a sealing structure between the unloading door and the container of the muck trucks and dump trucks for urban transportation, which is used to prevent the muck trucks from leaking and throwing along the way, causing secondary pollution and damage to the urban environment. Commonly used sealing structures between the unloading door and the container are: rubber pad sealing structure, inflatable sealing structure and intelligent inflatable sealing structure. [0003] Patent CN105109394 A discloses a dump truck and its compartment sealing mechanism, which belongs to an intelligent inflatable sealing structure. Such as figure 1 As shown, the booster device 1, the pressure reducing valve 2, the on-off valve 3 and the expansion sealing strip 4 are connected in series in sequence...
