Abstract

The invention discloses a novel operating handlebar mechanism for a chuck, and the mechanism comprises a handlebar and a support plate, which are connected together. The support plate is provided witha limiting block, and the handlebar comprises a straight end and a right-angle end. The support plate is located at the joint of the straight end and the right-angle end of the handlebar. The mechanism also comprises a fixing bolt, and the fixing bolt is fixed on a slip bowl through an annular chain. The mechanism is advantageous in that a person can easily lift a slip through the mechanism, andinsert the slip into the fixing bolt for dead locking of the handlebar, thereby preventing the slip from falling; the normal operation can be performed even if there is no pneumatic and hydraulic drive, thereby greatly improving the production efficiency; moreover, the handlebar is low in cost, thereby greatly reducing the production cost; the mechanism is high in popularization and practical values in the industry of oil equipment and other industries.

Description

technical field [0001] The invention relates to the field of equipment for chucks, in particular to a novel operating handle mechanism for chucks. Background technique [0002] During the operation of casing, drill pipe and tubing in oil production, chuck tools are often used to clamp the main casing or drill pipe, and the chuck is generally driven by pneumatic or hydraulic pressure. However, in the case of limited site conditions, pneumatic or hydraulic chucks cannot be used, which will affect production operations. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a new type of operating handle mechanism for the chuck. Its lever structure allows the operator to easily operate the slips in the chuck to open and close with one hand. [0004] The technical scheme adopted in the present invention is: [0005] A novel operating handle mechanism for a chuck includes a handle and a support plate connected togethe...
