Embodiment Construction

[0018] Such as figure 1 As shown, the hydraulic chuck slip loading and unloading device of the drilling rig in this embodiment is provided with a fixed collar 1 and a positioning pin 2 . The fixed ferrule 1 is provided with a cylindrical overcoat 3, and the periphery of the cylindrical overcoat 3 is welded and fixed with four positioning cylinders 4 at equal distances. The diameter of the cylindrical overcoat 3 is 2 times higher than the cylindrical overcoat 3. times, the diameter of the positioning cylinder 4 is a high 1 / 4th of the outer cover 3 of the cylinder.

[0019] Such as figure 2 , image 3 As shown, the positioning cylinder 4 communicates with the outer casing 3 of the cylindrical body, the outer end of the positioning cylinder 4 is provided with a positioning ring 5, and the outside of the positioning cylinder 4 is provided with a limiting hole 7 through which the limiting bolt 6 passes. The set internal thread corresponds to the external thread of the limit bol...

Abstract

The invention discloses a hydraulic chuck and slip assembling and disassembling device for drilling machines, and relates to the field of chuck and slip assembling and disassembling tools for drilling machines. Problems of high price, inconvenience in carrying and the like of existing chuck and slip mounting equipment are solved by the hydraulic chuck and slip assembling and disassembling device. The hydraulic chuck and slip assembling and disassembling device for the drilling machines comprises a fixing collar and positioning stoppers, three to four positioning barrels are equidistantly and fixedly welded at the peripheral edge of a cylindrical jacket, a positioning ring is arranged at the outer end of each positioning barrel, a limiting hole is formed in the outer side of each positioning barrel, limiting stoppers can penetrate the limiting holes, and internal threads formed in the limiting holes correspond to external threads of the limiting stoppers; each positioning stopper is provided with a square-head screw, a clamp ring and an extension sleeve, and limiting grooves corresponding to the limiting stoppers are formed in outer sides of the extension sleeves. The hydraulic chuck and slip assembling and disassembling device for the drilling machines has the advantages of simple structure, small size, light weight, portability and convenience in operation.

Description

technical field [0001] The invention relates to a drilling rig chuck slip loading and unloading tool, in particular to a drilling rig hydraulic chuck slip loading and unloading device. Background technique [0002] The special tools for drilling tools suspended at the wellhead are generally equipped with a hydraulic chuck device, and the slips in the hydraulic chuck device are usually composed of three or four pieces, and a spring is arranged between the slips to hold the Three or four slips with springs between the slips are installed in the hydraulic chuck, which requires special installation equipment. However, at present, the equipment specially installed with slips used by people is expensive, which increases the production cost of the enterprise; at the same time, the equipment specially installed with slips is bulky and heavy, and is inconvenient to carry, which seriously affects the installation efficiency of slips on the hydraulic chuck. Time-consuming. Contents ...
