The invention discloses a power-assisted anti-pinch engineering cart which comprises a cart body, a transmission cavity is formed in the cart body, wheel axles extending towards the front side and therear side are rotationally arranged on the front inner wall and the rear inner wall of the transmission cavity, wheels which are symmetrical front and back are fixedly arranged on the front end facesand the rear end faces of the wheel axles, and a balance detection cavity for detecting balance is formed in the inner wall of the left side of the transmission cavity/ By means of pneumatic loosening, power assisting during operation of the engineering cart is achieved, retreating actions are locked during uphill, safety accidents caused by sliding of the cart during uphill are avoided, reverserotation power is provided for the cart during downhill, danger caused by too fast downhill locking of the cart during downhill is avoided; and when the cart impacts a person, emergency braking is conducted, the distance between the cart and the impacted person is increased, subsequent injuries are reduced, meanwhile, an air film is formed between a cart hopper rotating shaft and a bearing in thepneumatic process, the friction force between the bearing and the shaft is reduced, a cart hopper is kept stable in the running process, and goods in the cart hopper are prevented from being scattered.

    本发明公开了一种动力辅助的防夹伤工程推车,包括车身,所述车身内设有传动腔,所述传动腔前后内壁上转动设有向前后两侧延伸的车轮轴,所述车轮轴前后端面上固定设有前后对称的车轮,所述传动腔左侧内壁上设有检测平衡的平衡检测腔;本发明通过气动的放松实现了工程推车运行时助力并在上坡时锁死后退动作,避免上坡时推车溜坡造成安全事故,在下坡时给予推车反转的动力,使推车在下坡时不至于下坡锁定过快出现危险,并在推车撞击到人时紧急制动并拉远与受到撞击者之间的距离减少后续伤害,同时在气动时车斗转轴与轴承之间形成气膜,减小轴承与轴之间的摩擦力,使车斗在运行过程中保持平稳,防止车斗内货物的洒落。
