Drill rod drawing device

Abstract

The invention discloses a drill pipe drawing device, which comprises a bottom component, a hydraulic cylinder and a top component, the bottom component is hingedly connected with the hydraulic cylinder, the top component is hingedly connected with the hydraulic cylinder, and the top component is provided with an inner The embedded device is arranged in the conical connecting cylinder of the top member. The device solves the problem of affecting the construction progress due to the locking of the drill pipe during the production process of the mine, and avoids the loss of the drill pipe due to the locking of the drill pipe in the rock mass and coal mass during the construction process, resulting in economic losses, resulting in equipment damage and personnel casualties. technical problem.

Description

technical field [0001] The invention relates to a drill pipe drawing device, in particular to a drill pipe drawing device for solving coal mine drill pipe locking. Background technique [0002] With the development of the economy, energy is still the foundation of the country's economic development, and coal, oil, and natural gas resources are the three major energy sources; coal resources are non-renewable resources, and as the shallow resources are gradually mined, they can only be mined deep. As the depth increases, the gas content of the coal seam is getting higher and higher, the gas fracturing is getting higher and higher, and the mining difficulty is getting more and more difficult; at present, the gas control is mainly divided into surface and underground control, but the main focus is on underground control. Moreover, the effect of underground gas control is relatively ideal. The measures for gas control at home and abroad mainly include: mining protective layer, de...

Problems solved by technology

[0003] With the development of new drilling rigs, the drilling depth of drilling rigs can reach hundreds of meters, and the geological conditions of coal mines are relatively complicated. Improper operation often occurs that the drill pipe of the drilling rig is locked in the rock mass and coal mass, causing underground construction to not proceed normally, and the drill pipe is lost in the coal mass and rock mass, resulting in a large number of drill pipe loss. At present, there is no real It is used for the equipment that the drill pipe is locked in the coal and rock during the construction process of the drill pipe in the coal mine. If the stuck drill is not very serious, the workers on the site generally use the power of the drilling rig to reverse, which can only deal with the stuck, and the strength is insufficient. If it is completely locked in the rock mass; if there is no way, the drill pipe will be lost. In the process of mining coal resources, there will be a great safety hazard, causing damage to the fully mechanized mining machine and casualties, affecting production and causing economic losses
