Abstract

The invention discloses a rail type iron roughneck spinning wrench. The rail type iron roughneck spinning wrench comprises a mounting support, a shackle frame is connected in the mounting support, two first fixing bases are mounted on two sides of the rear end of the mounting support respectively from top to bottom, guide rods correspondingly penetrate the first fixing bases on two sides, a first slider assembly and a second slider assembly are mounted in the guide rods along two sides of second fixing bases symmetrically, and a first hydraulic oil cylinder is hinged between the first slider assembly and the second slider assembly. Two sliders are arranged in the first slider assembly and the second slider assembly respectively. The first slider assembly and the second slider assembly are in transmission connection with respectively second hydraulic oil cylinders on two sides. Two motor assemblies are mounted in the first slider assembly and the second slider assembly respectively. The rail type iron roughneck spinning wrench is simple in structure and convenient to demount.

Description

technical field [0001] The invention belongs to the technical field of petroleum machinery and relates to a rail-type iron driller's turnbuckle pliers. Background technique [0002] At present, the rail-type iron driller's turnbuckle usually used in oil drilling rigs has the following shortcomings due to the design structure limitation. One is that the connecting rod is used to push the slider to move, and the motion trajectory cannot be completely straight; the other is that an oil cylinder is used as a The power and the synchronization of the movement of the sliders at both ends cannot be fully guaranteed; the third is that there is no cleaning mechanism, and the drilling tool and its joints cannot be cleaned in time to facilitate joint connection; the fourth is that it adopts a shell packaging structure, which is not easy to install and maintain. Contents of the invention [0003] The purpose of the present invention is to provide a rail-type iron driller's turnbuckle, ...
