Abstract

The invention relates to a tube seam type anchor rod drawing instrument and a drawing method thereof, and belongs to the technical field of mineral engineering. The tube seam type anchor rod drawing instrument comprises a jack, a support component, a main shaft, a force bearing base, a sliding base, a tension shaft, a supporting shaft, a top base and a grabbing ring, the jack is fixedly arranged at the top end of the support component, the main shaft is coaxially and fixedly arranged at the bottom end of the jack, and the force bearing base is arranged on the main shaft in a sleeving mode; the jack, the main shaft and the force bearing base form an anchor rod drawing component; the sliding base is arranged on the main shaft in a sleeving mode and located below the force bearing base, and the force bearing base is connected with the sliding base through the force bearing rod. The tension shaft is arranged on the side face of the sliding base through a rotating base. The grabbing ring is fixedly arranged at the bottom end of the tension shaft. The top base is fixedly arranged at the bottom end of the main shaft, the A end of the supporting shaft is arranged on the side face of the top base, and the B end of the supporting shaft is hinged to the tension shaft. The grabbing ring at the end of the tension shaft gets close to or away from the center line of the main shaft by moving the sliding base so that the tube seam type anchor rods with different diameters are matched in the test.

Description

technical field [0001] The invention relates to a pipe slit type bolt puller, which belongs to the field of mining engineering. Background technique [0002] Anchor puller is used to test the pull-out resistance of various anchors, steel bars and other anchors. It is a necessary testing instrument for quality inspection units. The commonly used bolt puller is composed of manual pump, hydraulic cylinder, intelligent digital display pressure gauge, reaction support ring, anchorage and so on. When using, first select the corresponding anchor, install the reaction support ring, oil cylinder, and anchor in sequence, then connect the manual pump, pressurize the hydraulic cylinder through the manual pump, and read the pressure gauge to check the pullout force of the anchor. Determination, after dismantling the instrument, if there is no crack or other local damage in the concrete, it should be evaluated as qualified. The pipe slot bolt is a new type of full-length anchor that act...
