The invention relates to the technical field of electric power transportation equipment, in particular to an electric power transportation trolley which comprises a trolley frame, left connecting rods, right connecting rods, a hydraulic oil cylinder and a bottom plate, wherein a plurality of traveling wheels are arranged at intervals at the lower side of the trolley frame. The electric power transportation trolley is reasonable and compact in structure and convenient to use. The left connecting rods and the right connecting rods are arranged to form a parallelogram mechanism with the bottom plate and the trolley frame. Through the extension action of a piston rod, the upper ends of the left connecting rods can swing rightwards so as to achieve the lowering action of the bottom plate. Through the arrangement of a horizontal rod, the force of the piston rod can be uniformly distributed to the left connecting rods so as to avoid the situation that the force at the connection of one of theleft connecting rods and the piston rod is excessive resulting in deformation or breakage of the left connecting rod, so that the situation that the bottom plate can not be supported by the left connecting rods and then falls quickly and collides with the trolley frame resulting in damage of equipment on the bottom plate or safety accidents is avoided. The arrangement achieves the uniform force receiving and synchronous action of the left connecting rods, and the bottom plate is more stable during lifting and lowering. The electric power transportation trolley has the characteristics of beingsafe, labor-saving, simple, convenient and efficient.

    本发明涉及电力运输设备技术领域,是一种电力运输小车,包括车架、左连杆、右连杆、液压油缸和底板,车架下侧间隔设有若干个行走轮。本发明结构合理而紧凑,使用方便,通过设置左连杆和右连杆,能够和底板以及车架形成平行四边形机构,通过活塞杆的伸长动作能够使左连杆上端向右摆动,继而实现底板的下降动作,通过设置横杆,能够将活塞杆的力均布于左连杆,避免一个左连杆和活塞杆连接处受力过大造成左连杆变形或者断裂,从而失去活塞杆的支撑使底板迅速下落与车架发生碰撞,继而损毁底板上的设备或造成安全事故,这样的设置能使左连杆受力均匀并实现同步动作,底板在升降过程中更加稳定,具有安全、省力、简便、高效的特点。
