Tube drawing auxiliary device applied to on-site mixed emulsion explosive loading procedure

Abstract

The invention discloses a tube drawing auxiliary device applied to an on-site mixed emulsion explosive loading procedure. A supporting disc is fixedly arranged at the upper end of a positioning tube in a sleeved mode, a rotary support is composed of an upper round disc part and a lower sleeve-shaped part, central holes of the two parts are concentric, and the rotary support is installed at the upper end of the positioning tube in a sleeved mode through a bearing. A supporting frame is fixedly arranged on the top surface of the round disc part of the rotary support, at least one guide wheel is horizontally arranged on the supporting frame, and the two ends of a supporting shaft of the guide wheel are inserted into corresponding installation holes in the supporting frame. The axis of the guide wheel is perpendicular to the axis of the positioning tube, and an arc-shaped guide groove is formed in the outer circumferential surface of the guide wheel in the circumferential direction. The auxiliary device is matched with a coiling disc on an explosive loading cart to achieve automatic tube drawing, manpower is basically not needed in the tube drawing process, an explosive conveying tube has no friction with the rock at the opening of a blasthole, the explosive conveying tube is not prone to loss, and the use cost is lowered. The coiling disc can pull the explosive conveying tube only with small input power, and the energy consumption is low.

Description

technical field [0001] The invention belongs to the field of emulsified explosive charging, and in particular relates to an auxiliary device for extubating tubes used in the on-site mixing emulsified explosive charging process. Background technique [0002] On-site mixing of emulsion explosives is the development direction of the civil explosives industry, but the following problems still exist in the process of charging emulsion explosives into blastholes. [0003] 1. Many blasting construction sites still use manual extubation to charge the explosives. The specific operation method is to pump the emulsified explosives into the blast hole by two or more workers manually. This method is not only labor-intensive, but also if there is water accumulation in the blast hole, if the speed of pulling out the tube does not match the charging efficiency, it will cause the accumulation of water to stay in the emulsion explosive, thus Affects blasting effects. [0004] 2. In some bla...
