Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of placing a fracturing tube for mines, in particular to a quick fracturing tube lowering device suitable for mines. BACKGROUND

[0002] The fracturing tube is a tubular device that can cause rock / concrete to break in a specific direction by generating an impact wave or high-pressure fluid through internal charging. According to relevant regulations, the operator during the installation process of the fracturing tube must hold a blasting operation license (primary / advanced) and have undergone special training on the fracturing tube. Non-licensed personnel are strictly prohibited from touching the installation process.

[0003] During the lowering process of the fracturing tube, the diameter of the fracturing tube is between 32-90mm, and the length is between 0.5m-6m. Therefore, at least three people are required to install some longer fracturing tubes. One person holds the fracturing tube to facilitate its smooth entry into the upper port of the blast hole, so that the fracturing tube can be guided in the hole by the guide sleeve in the blast hole. One person operates the pressure tool to press the fracturing tube into the hole, and one person observes to stop at any time.

[0004] During the installation process, three controls must be ensured: uniform speed (velocity), constant pressure (pressure), and low frequency (vibration frequency <10Hz). Double protection mechanisms are adopted: physical damage prevention (guiding device) + chemical protection (lubrication / waterproof medium). According to the actual measurement data, the use of mechanical jacking combined with a polymer centralizer can increase the in-place rate of deep hole (>20m) fracturing tubes from 78% to 99.2%.

[0050] In step 5, some blast holes are inclined, so the third telescopic rod 16 needs to be adjusted to pull the fracturing tube 5 horizontally, adjust the horizontal inclination angle of the fracturing tube 5; by rotating the second adjusting device 3, the longitudinal inclination angle of the fracturing tube 5 is adjusted, so that the inclination direction of the fracturing tube 5 is the same as the inclination direction of the blast hole. In this way, the fracturing tube 5 can quickly and smoothly enter the out-of-hole guide 8, reducing the operating strength of the operator and improving the work efficiency.
