Hoisting device for overhauling jackdrill head of mining trolley and hoisting method

Abstract

The invention provides a hoisting device for overhauling a jackdrill head of a mining trolley and a hoisting method. The hoisting device comprises an upper hoisting part and a lower hoisting part, wherein the upper hoisting part is composed of a T-shaped steel structure and a lower circular ring welded on the lower end of the T-shaped steel structure; the lower hoisting part is composed of an inner thread sleeve and an upper circular ring welded with the upper end of the sleeve. The hoisting method comprises the following steps: putting the upper hoisting part into a hole of a rod clamping device above a rack and fixing the upper hoisting part by the rod clamping device; hanging an upper lifting hook of a chain block on the lower circular ring of the upper hoisting part; screwing the inner thread sleeve of the lower hoisting part on a thread bit shank rod of the jackdrill head; hanging a lower lifting hook of the chain block on the upper circular ring of the lower hoisting part; operating the chain block. According to the hoisting device and the hoisting method, the problems that the previous normal overhauling of the jackdrill head influences the production, is limited by various conditions, causes inconvenience for work and the like are overcome, and the convenience is provided for the normal overhauling of the jackdrill head.

Description

technical field [0001] The invention belongs to hoisting operation technology, in particular to a hoisting device and a hoisting method for overhauling a rock drilling head of a mining jumbo. Background technique [0002] The rock drilling head of the mining trolley (hereinafter referred to as the head) has a self-weight of 200-300 kg and is fixed on the head slide, so the head can slide on the head slide for rock drilling operations. When there is a problem with the head of the mining trolley, it must be repaired or replaced. When repairing or replacing, the head of the mining trolley must be hoisted. At present, when hoisting, the mining trolley must be driven to a place that can be hoisted, such as the overhaul room or the place where there is a crane in the underground. Sometimes it needs to be driven to the surface or lifted to the surface for hoisting. The machine head and the machine head slide plate can only be installed vertically on the machine head slideway, and ...
