Abstract
The utility model relates to a tilting prevention device of a construction lifting platform. A left platform and a right platform are respectively hinged with two upper sides of a main platform. The lower parts of the left platform and the right platform are respectively hinged with two ends of a tie rod. One end of a tension spring is fixed on a frame and another end is hinged with a tie plate. An eccentric wheel is mounted on the tie plate and the force is transferred to the eccentric wheel by the eccentric wheel to make the eccentric wheel rotate. A rack is arranged at one side of the eccentric wheel. The eccentric wheel rotates and its surface gradually is near to the back of the rack to adhere with the back of the rack under the function of the eccentric moment. The beneficial effects are that: the movement distance of the tie rod is lengthened along with the increased partial weight of the working platform at one side and the transfer force is gradually increased and the eccentric wheel closely abuts on the back of the rack and the relative movement of the eccentric wheel and the rack is stopped by the friction force between the surface of the eccentric wheel and the back of the rack, thus the construction lifting platform stops moving, thereby preventing the construction lifting platform from tilting due to overlarge partial weight.
