The invention discloses a double-layer chassis device with good stability. The double-layer chassis device comprises a fixed seat and a supporting column arranged in the middle of the fixed seat, a rotating disc is arranged at the upper end of the supporting column, the upper end of the rotating disc is rotationally connected with a cargo boom through a fixed block, and a movable seat used for increasing the supporting area is arranged at the upper end of the fixed seat; the movable seat comprises a plurality of sliding transverse plates distributed in an array mode, supporting feet are arranged at the outer ends of the sliding transverse plates, supporting wheels are arranged at the lower ends of the supporting feet, the supporting wheels are tangent to the plane where the lower end faceof the fixed seat is located, a fixed sleeve coaxial with the fixed seat is arranged at the upper end of the fixed seat on the outer side of the supporting column, a top plate is arranged at an upperport of the fixed sleeve, and a positioning disc is arranged on the lower end of the fixed sleeve. According to the double-layer chassis device with good stability, the device is designed for overcoming the defects of an existing device, the fixed seat and the movable seat capable of adjusting the supporting area are arranged, the direction of increasing the supporting area is consistent with thedumping direction of the cargo boom, the stability of the device is effectively improved, and the practicability is high.

    本发明公开了一种稳定性好的双层底盘装置,包括固定座和设置在其中间位置的支撑柱,所述支撑柱上端设有转动盘,转动盘上端通过固定块转动连接起重臂,所述固定座上端设有用于增大支撑面积的活动座,所述活动座包括若干个阵列分布的滑动横板,所述滑动横板外端设有支撑脚,支撑脚下端设有支撑轮,所述支撑轮与固定座下端面所在平面相切设置,所述支撑柱外侧的固定座上端设有与之同轴设置的固定套,固定套上端口处设有顶板,所述固定套下端设有定位盘,本发明针对现有装置的弊端进行设计,设置固定座和可调节支撑面积的活动座,增大支撑面积的方向与起重臂倾倒方向一致,有效的提高了装置的稳定性,实用性强。
