Abstract

The invention provides a novel heat-resistant high-strength full-length anchoring resin anchoring agent loading auxiliary device and a propelling auxiliary device. A full-length anchoring resin anchoring agent is loaded into loaded by the loading auxiliary device and then conveyed into an anchor hole, then an anchor rod is fed into the anchor hole and propelled by the propelling auxiliary device,and the vibrates and tampes the full-length anchoring resin anchoring agent, so that the anchor hole is uniformly filled with the full-length anchoring resin anchoring agent. Two ends of the loading auxiliary device are semicircular pipes, and the middle part of the loading auxiliary device is a whole cylinder. Under reasonable cooperation of auxiliary construction equipment such as the loading auxiliary device and the propelling auxiliary device and existing supporting machine tools, a rapid labor-saving safe construction process of the full-length anchoring resin anchoring agent is realized,and powerful construction quality and safety guarantee are provided for next deep mining of a coal mine.

Description

technical field [0001] The invention belongs to the technical field of mine support materials, and in particular relates to a loading auxiliary device and a propulsion auxiliary device of a novel heat-resistant high-strength full-length anchoring resin anchoring agent. Background technique [0002] Resin anchoring agent has fast curing and high strength, can realize rapid support of mines and foundation pits, and has simple construction technology, so it is widely used. Resin anchoring agent is generally composed of unsaturated polyester resin, high-strength filler, curing agent and accelerator. Resin anchoring agent is the main material for mine support. This material can bond metal and non-metallic materials between the same species or between each other. It has the advantages of no expansion and extrusion force on the foundation hole, and the anchoring depth is not limited. [0003] Existing resin anchoring agent takes unsaturated polyester resin as binding agent, coarse...
