Problems solved by technology

Drill pipe collars or joints are used for the connection between downhole geological drill pipes, so that the drill pipes can be lengthened to a predetermined length for rock drilling. The connection between them is not firm, and the use affects the normal function of the drilling rig; therefore, it is necessary to regularly dismantle and replace the drill pipe collar or joint; the traditional process of dismantling and replacing the drill pipe collar or joint is done manually. The safety factor of the replacement method is low, the operation is more cumbersome, and it slows down the work efficiency and affects the work progress

Abstract

The invention discloses a dismounting and replacing device for a drill pipe coupling or joint, and relates to the technical field of drill pipe dismounting and replacing. The dismounting and replacingdevice comprises a base, wherein a notch and a limiting plate are arranged at the front end of the base; a door-shaped frame and a lifting device are fixed on the upper surface of the base; a first clamping device is arranged on one side of the top of the door-shaped frame in a sliding fit mode; a feeding device is fixed in the middle of the door-shaped frame, and a second clamping device is fixed at the end part of the feeding device; a fixing seat is arranged at the top end of the lifting device; and the second clamping device comprises two side strips which are oppositely arranged on the two sides of a transverse plate, and the opposite inner sides of the top ends of the two side strips are fixedly connected with clamping frames through first telescopic rods. According to the dismounting and replacing device, a drill pipe and the drill pipe coupling are sequentially fixed through the fixing seat and the second clamping device, the drill pipe coupling is disassembled step by step, the drill pipe coupling is installed through the cooperation of the feeding device and the second clamping device, the dismounting and replacing speed of the drill pipe coupling is increased, and the working efficiency of a drilling machine is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of drill pipe replacement, in particular to a device for removing and replacing drill pipe collars or joints. Background technique [0002] A drilling rig is a complex set of machines, which consists of machines, units and mechanisms. A drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data during exploration or mineral resource development (including solid ore, liquid ore, gas ore, etc.). Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to prove the underground geology and mineral resources. Drill pipe is a steel pipe with threads at the end, also known as drill pipe, which is used to connect the surface equipment of the dril...
