Rubbing plate device for screwing and detaching drill rod

Abstract

The invention provides a rubbing plate device for screwing and detaching a drill rod. Two cross-shaped reinforced ribs are arranged inside a hand wheel of the rubbing plate device; an opening is formed on the hand wheel, an upper cover plate and a lower cover plate are respectively arranged at the edges of the bilateral sides of the opening, and an arc-shaped fixed slip is fixedly arranged at the top of the opening through a bolt; a flexible slip is connected to the upper cover plate and the lower cover plate on one side of the opening through a cam, a handle which is connected with one end of a spring is fixedly arranged on the upper portion of the flexible slip, and the other end of the spring is connected to a spring column; and the flexible slip can be adjusted by rotating the cam. The rubbing plate device for screwing and detaching the drill rod has the advantages of improving the work efficiency; preventing the drill rod from falling off in the drilling process and effectively reducing the labor intensity of operating personnel due to the fact that a rubbing plate can screw down a screw thread of the drill rod when screwing and detaching the drill rod; being convenient to perform the machining production, simple in use and maintenance and convenient to carry as a special tool for screwing and detaching the drill rod; being suitable for engineering geological surveying and drilling industry of water or land, such as the port and the industry and civil; being easy to carry, light and handy in use and durable.

Description

technical field [0001] The invention relates to a disc rubbing device for unscrewing and unloading drill pipes, which is applied to water area, land area engineering geology and hydrogeological survey industries. technical background [0002] In the previous engineering geological drilling projects, due to the generally shallow drilling and relatively light drilling equipment, heavy special equipment such as hydraulic pipe twisters were not used when lifting and unloading the drill pipes, but hand twisting and pipe wrench were often used. , Drill pipe holder and other portable tools to connect and unscrew the drill pipe. These commonly used working methods generally have the problems of high labor intensity, cumbersome operation, and low efficiency, and there are often safety accidents such as pinching hands and bruising operators' legs and arms. If adopt a kind of portable and practical tool for unscrewing and unloading the drill pipe, it will be very convenient for operat...
