Carriage with replaceable carriage bottom plate, and supporting protecting mechanism

Abstract

The invention discloses a carriage with a replaceable carriage bottom plate, and a supporting protecting mechanism. The carriage capable of replacing the carriage bottom plate and the supporting protecting mechanism comprises the carriage and a supporting mechanism below the carriage on a side-turning side; the bottom plate of the carriage is of a double-layer structure, and comprises a lower bottom plate which is integrated with side plates of the carriage; guide rails are distributed on the lower bottom plate; the space between every two adjacent guide rails is filled with a plurality of rubber blocks; the guide rails are matched with an upper bottom plate; the supporting mechanism comprises a turnover supporting oil cylinder and an overturning oil cylinder for driving the supporting oil cylinder to overturn; the supporting oil cylinder is mounted on a turnover mounting seat below a chassis on the side-turning side; the extending end of a piston rod of the supporting oil cylinder is downward; a supporting plate is mounted at the extending end; a guide sliding mechanism is mounted on the chassis on the inner side of the supporting oil cylinder; the guide sliding mechanism comprises a movable inclined push rod. According to the carriage capable of replacing the carriage bottom plate and the supporting protecting mechanism, only the upper bottom plate is required to be replaced without replacing the whole body, so that materials are saved; a potential safety hazard caused by a side turning phenomenon is avoided through the structural arrangement of the supporting mechanism; therefore, the carriage capable of replacing the carriage bottom plate and the supporting protecting mechanism are safe and reliable.

Description

[0001] Technical field: [0002] The invention relates to the field of dump trucks, and mainly relates to a compartment with a replaceable compartment floor and a support and protection mechanism. [0003] Background technique: [0004] With the development of the construction industry and the increase in engineering volume, the sales and use of dump trucks have also greatly increased. Dump trucks are generally used to transport bulk materials, but sometimes they need to be used to transport heavier materials, such as stone, cement, concrete, etc. required for construction sites, which require a large amount of materials, and small or medium-sized dump trucks are far from enough. Requirements, so a large rollover dump truck is used. The existing large-scale rollover dump truck has a simple structure. Due to the relatively heavy material, it will be unstable when rolling over. If the ground is uneven, it is easy to rollover, which brings potential safety hazards. At the same ti...

Dump trucks are generally used to transport bulk materials, but sometimes they need to be used to transport heavier materials, such as stone, cement, concrete, etc. required for construction sites, which require a large amount of materials, and small or medium-sized dump trucks are far from enough. requirements, so large rollover dump trucks are used

The existing large-scale rollover dump truck has a simple structure. Due to the relatively heavy material, it will be unstable when rolling over. If the ground is uneven, it is easy to rollover, which brings potential safety hazards. At the same time, the chassis is easily deformed by force. and damage; and the existing dump truck floor generally adopts an integral welded structure. During its use, due to bumps, twists, and dents, it is prone to damage if it continues to be used, and it needs to be replaced as a whole. caused a lot of waste of resources
