The invention discloses an anchor rod heating device, in particular to an anchor rod resistance heating furnace. The anchor rod resistance heating furnace comprises a heating furnace body, an anchor rod bracket, an anchor rod and a temperature measuring element, wherein the heating furnace body comprises a hollow furnace chamber; a heating element is arranged in the furnace chamber; the heating furnace body is also provided with a furnace door which is communicated with the furnace chamber; one end of the anchor rod extends into the furnace chamber through the furnace door to be heated, and the other end of the anchor rod is arranged on the anchor rod bracket; the anchor rod bracket is used for supporting the anchor rod in heating; the temperature measuring element is arranged above the heating furnace body for measuring the temperature in the furnace chamber. According to the anchor rod resistance heating furnace, the problems of high energy consumption and environmental pollution of a coal-fired heating furnace and expensive equipment and low production efficiency of a high-frequency induction heating furnace are solved, the resistance heating furnace is innovatively used, the anchor rod can be quickly and stably heated, and the production efficiency is high.
Description
technical field [0001] The invention relates to an anchor rod heating device, in particular to an anchor rod resistance heating furnace. Background technique [0002] Anchor is the most basic part of roadway support in contemporary coal mines. It reinforces the surrounding rock of the roadway so that the surrounding rock can support itself; Connection, the other end goes deep into the formation, the whole bolt is divided into a free section and an anchor section, the free section refers to the area where the tensile force at the head of the anchor is transmitted to the anchor body, and its function is to apply prestress to the anchor; the anchor section It refers to the area where the cement paste bonds the prestressed tendons to the soil layer. Its function is to increase the bonding friction between the anchor body and the soil layer, increase the pressure bearing effect of the anchor body, and transfer the tensile force of the free section to the soil layer. body depths....
