The utility model provides a lifting and anti overturning device of a dump truck. At the tail end of the chassis frame, there is a through beam which is vertically connected with the longitudinal beams on both sides. The two sides of the through beam are hinged with hydraulic cylinders through the cylinder bracket, and the end of the piston rod extending downward from the hydraulic cylinder is connected with the ground support plate; the middle position of the through beam is provided with an electric rope winder, and two of the electric rope winders are extended reversely The steel wire ropes are respectively connected to the outer walls of the hydraulic oil cylinders on both sides of the through beam, and the hydraulic oil cylinders are retracted along the hinge axis through the middle position of the through beam through the steel wire ropes on the electric rope winder. The utility model contacts with the ground through the ground support plate after the hydraulic oil cylinder piston is extended, so as to increase the contact point between the whole vehicle and the ground, at the same time, the width is suitable for the width of the carriage to avoid interference, which can effectively prevent the lifting and rollover of the cargo compartment; after the use, the hydraulic oil cylinder retracts the piston rod, and the hydraulic oil cylinders on both sides are lifted to the middle and retracted back to the through beam through the electric rope reeler, which is not Affect the passing performance of the whole vehicle.

一种自卸车举升防翻装置
本技术涉及自卸车安全
,具体涉及一种自卸车举升防翻装置。
技术介绍
传统自卸车是通过在货厢的前端或中部安装举升液压油缸及相关液压举升零部件举升货厢,货厢举升一定角度后靠货物自身重力作用下滑出货厢达到自动卸货的目的。自卸车在举升货厢的过程中稳定性非常差,路面、货物、操作习惯等因素均会造成汽车侧翻,安全性较差。为了克服上述弊端,专利申请号为200520200869.7的《自卸汽车车厢举升稳定支撑装置》中的液压支腿能够在举升过程中起到稳定作用,但操作不方便,影响通过性能;专利号申请号为200720182812.8《汽车自卸防翻安全装置》,采用油缸推杆和折叠支架,依靠折叠支架与地面形成支撑,这种折叠支架通过折叠使通过性增加,但整车尾部布置折叠支架的空间较小,同时折叠支架的强度不够,针对货厢较大的车型则不适用。
技术实现思路
为了解决上述技术问题,本技术提出了一种自卸车举升防翻装置。为此,本技术的技术方案为:一种自卸车举升防翻装置,其特征在于:底盘车架尾端固定有与两侧纵梁垂直连接的贯通梁,贯通梁的两侧通过油缸支架铰接有液压油缸,液压油缸向下伸出的活塞杆端部连接有地面支撑板;贯通梁的中间位置设有电动卷绳器,电动卷绳器中反向伸出有两根钢丝绳并分别连接在贯通梁两侧液压油缸的外壁上,液压油缸通过电动卷绳器上的钢丝绳沿铰接轴向贯通梁中间位置收起。对上述技术方案的进一步改进在于:所述电动卷绳器包括底板和设在底板两侧的支座,两个支座的之间转动连接有圆柱体形的长条传动齿 ...
