Abstract

Disclosed is an oil cylinder type balance lifting ring device. The oil cylinder type balance lifting ring device is characterized by comprising an upper lifting ring, side lifting rings, pin shafts, balance oil cylinders, upper supports and lower supports; the upper lifting ring and the side lifting rings are arranged above the device, the side lifting rings are provided with pin holes, the upper supports and the lower supports of the balance cylinders are arranged on the middle portions of the side lifting rings, upper ends of the side lifting rings respectively penetrate the pin holes, the side lifting rings are connected through pin shafts, lower ends of the side lifting rings are connected with box bodies of reduction boxes of a top drilling-machine driving system through the pin shafts, and upper ends of the balance cylinders are connected with the upper supports through the pin shafts. The oil cylinder type balance lifting ring device has the advantages of reasonable structure, convenience in mounting, simpleness in structure, high sense of balance and the like.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, and in particular provides an oil cylinder type balance lifting ring device. Background technique [0002] The existing lifting ring device, the external structure is provided with a left lifting ring, a right lifting ring and a middle lifting ring. The upper earring of the oil cylinder is connected to the pole beam through the pin shaft, and the lower earring is also connected to the balance cylinder base fixed on the lifting rings on both sides through the pin shaft. The conventional lifting ring used needs to install pole beams, bolts, and balance bases at the drilling site, and adjust the balance positions of each component. The installation work is cumbersome, and the balance effect in the actual work process is not ideal at the same time. Contents of the invention [0003] The purpose of the present invention is to solve the problems of cumbersome operation and complicated ins...
