A kind of iron diamond rotation clamp lift mechanism

Abstract

The invention discloses a lifting mechanism for an iron driller's turnbuckle pliers, which comprises a support frame assembly, and composite roller bearing groups are installed on the left and right sides of the support frame assembly; the support frame assembly moves up and down in the guide body assembly; Composite roller bearings are installed on the left and right sides of the body assembly, and the guide body assembly moves up and down in the frame body assembly; the upper end of the guide body assembly is connected with the support cylinder; the lower end of the support cylinder is hinged with the frame body assembly through a pin shaft ; The connecting seat is connected with the frame body assembly by bolts; one end of the hoisting chain is fixed on the lock a through the connecting shaft a, the other end of the lifting chain is fixed on the lock b through the connecting shaft b, and the lock b passes through The bolt is fixed on the connecting seat; the sheave is installed on the sheave shaft through the self-lubricating bearing; the extension or retraction of the support cylinder realizes the up and down movement of the support frame assembly and the guide body assembly, so as to realize the up and down movement of the turnbuckle machine move. The invention has simple structure, convenient disassembly and assembly and maintenance.

Description

Technical field [0001] The present invention belongs to the technology field of petroleum drilling equipment and involves a kind of iron diamond rotor clamping mechanism. Background technique [0002] At present, the iron diamond rotor rotor clamping mechanism is usually used by the petroleum rig. Due to the limitation of the design structure, the device has the following shortcomings. One is to use the roller chain driver, the carrying capacity is low, and it is not easy to maintain. The friction force is large, easy to get stuck, and the synchronization of slider on both sides cannot be completely guaranteed; the third is the limitation of the space structure, which is not easy to maintain and install. Invention content [0003] The purpose of the present invention is to provide an iron diamond rotation clamp lift mechanism, which solves the unreasonable structure settings in existing technologies. The friction board is used as a guidance, large friction, and easy to get stuck...
