The engineering cart for building construction comprises a cart body and wheels, a wheel cavity is formed in the wheels in a penetrating mode, a rotating shaft sleeve is fixedly arranged at the axis position in the wheel cavity, a shearing main plate is arranged between the outer circle face of the rotating shaft sleeve and the inner circle walls of the wheels, and symmetrical shearing devices are arranged in the shearing main plate; the shearing device comprises symmetrical springing cavities formed in the shearing main plate, shearing sliding blocks are slidably arranged in the springing cavities, symmetrical limiting sliding grooves are formed in the sides, away from openings, of the springing cavities in a communicating mode, and symmetrical limiting sliding plates extending into the limiting sliding grooves are fixedly arranged on the end faces of the sides, away from the openings of the springing cavities, of the shearing sliding blocks. A limiting hole penetrates through the limiting sliding plate on one side far away from the rotating shaft sleeve, and an inserting strip hole penetrates through the limiting sliding plate on one side close to the rotating shaft sleeve. Objects such as branches which are accidentally rolled into the middles of the wheels can be cut off, and the situation that the cart inclines and even turns over due to the fact that the wheels are clamped by the branches and the like is avoided.

    本发明公开了一种建筑施工用工程推车,包括车体和车轮,车轮内贯通设置有车轮空腔,车轮空腔内轴心处固定设置有转动轴套,转动轴套外圆面与车轮内圆壁之间设有剪切主板,剪切主板内设置有对称的剪切装置,剪切装置包括开设于剪切主板内且对称的弹动腔,弹动腔内滑动设置有剪切滑块,弹动腔远离开口一侧连通设置有对称的限位滑槽,剪切滑块远离弹动腔开口一侧端面固定设置有对称且延伸至限位滑槽内的限位滑板,远离转动轴套一侧的限位滑板内贯通设置有限位孔,靠近转动轴套一侧的限位滑板内贯通设置有插条孔。本发明能够将意外卷入车轮中部的树枝等物切断,避免出现树枝等卡死车轮而使推车倾斜甚至侧翻。
