The invention relates to the technical field of hoisting machinery, and discloses an anti-collision electric hoist which comprises a main machine, fixing plates are fixedly connected to the two sides of the upper portion of the main machine, a driving motor is fixedly installed on one side of each fixing plate, and walking wheels are fixedly connected to the output shaft end of each driving motor. Through the arrangement of auxiliary wheels, friction blocks, movable blocks and brake rods, when normal braking is carried out, the brake rods in second cavities on the two sides of the upper portion move inwards, the movable blocks in a contraction state are jacked open through a round top plate, the friction blocks are expanded outwards, and the friction blocks make contact with I-shaped steel for friction braking; the friction blocks can greatly reduce the contact pressure between the walking wheels and the I-shaped steel rail and even lift the walking wheels, abrasion of the walking wheels caused by sliding of the walking wheels and the I-shaped steel rail under huge pressure can be avoided, abrasion of the walking wheels is reduced or even eliminated, and the service life of the walking wheels is prolonged.
本发明涉及起重机械技术领域,且公开了一种防撞型电动葫芦,包括主机,所述主机上部的两侧均固定连接有固定板,所述固定板的一侧固定安装有驱动电机,所述驱动电机的输出轴端固定连接有行走轮。通过辅助轮、摩擦块、活动块、制动杆的设置,使得在进行正常制动时,上方两侧第二空腔内部的制动杆均向内移动,将圆形顶板将处于收缩状态的活动块顶开,使得摩擦块向外张开,使摩擦块与工字钢接触进行摩擦制动,摩擦块会极大的减小行走轮与工字钢轨的接触压力,甚至将行走轮抬起,能够避免行走轮与工字钢轨在巨大压力发生滑动时造成行走轮的磨损,降低甚至取消行走轮的磨损,延长行走轮的使用寿命。
