Abstract
The invention relates to a novel tower crane for a counterweight balance mechanism and reforming and upgrading of the tower crane. The lifting capacity is improved. The implementation scheme is characterized in that the counterweight force on a counterweight arm of the tower crane is changed into a tension mode of a steel zipper; the upper end of the steel zipper is fixed to the tail part of a balance arm of the tower crane, and the lower end of the steel zipper is connected with a track sliding vehicle mechanism in a sliding chute integrally embedded through a tower crane base foundation and a counterweight water tank by pulling. During lifting operation, a sliding vehicle dynamically transmits the counterweight pulling force to the foundation by sliding the sliding chute, and the counterweight pulling force is counteracted with the pressure of a tower body, and meanwhile the sliding vehicle and a crane jib synchronously carry out rotating and lifting operation at the same angle. The lifting weight is transmitted to the crane jib through a lifting steel wire rope, and then the crane jib transmits the lifting weight to the top of the tower body by obliquely pulling the steel zipper. The pulling forces of the crane jib and the balance arm are changed into pressure through top of the tower body and transmitted to a ground foundation through the tower body. The pulling force of the crane jib to the tower top is larger than that of the crane jib to the balance arm and is the counterweight force of the novel tower crane of the counterweight balance mechanism, and the force is automatically increased and decreased along with the increasing and decreasing of the weight of a lifting object. The automatic counterweight balance of the tower crane is realized, and the lifting capacity and the safety are improved.
