Overall drawing test device for mining anchor rod

Abstract

The invention discloses an overall drawing test device for a mining anchor rod, relating to the field of mining anchor rod test and aiming at providing an adaptive test device for the mining anchor rod. The overall drawing test device for the mining anchor rod comprises a movable beam (1), a first guide rail (2), a drawing oil cylinder (3), a pull rod (4), an oil cylinder seat (5), a transverse beam (6), a front clamping head (7), a rear clamping head (8) and a pin shaft (9), wherein a first rolling wheel (10) capable of rolling along the first guide rail (2) is arranged on the movable beam (1); the oil cylinder seat (5) is fixedly connected to the transverse beam (6); a second guide rail (11) is paved on the transverse beam (6); and a row of first pin shaft holes (12) are arranged in the transverse beam (6). According to the overall drawing test device for the mining anchor rod, an overall drawing performance test function of the mining anchor rod is realized; and the overall drawing test device has the characteristics of simple structure and adjustability for test height.

Description

technical field [0001] The invention relates to a mine bolt test device, in particular to a mine bolt integral pull-out test device. Background technique [0002] With the development of coal mine roadway support technology, especially the promotion of large mining height fully mechanized caving mining technology, mine bolt support equipment has become more and more widely used, and has developed from the original rock roadway support form to coal roadway support. The quality of mining bolt products directly affects the level of shaft support. According to the requirements of the corresponding coal industry standards, anchor bolts should be tested for anchoring force performance indicators to determine the anchoring characteristics of the anchor bolts. At present, there is no overall pull-out test device for anchor bolts in my country. The rock bolt body can be cut into short sections, and the universal material testing machine can be used for testing, but the current situat...

AI Technical Summary

Problems solved by technology

According to the requirements of the corresponding coal industry standards, the anchor bolt should be tested for the anchoring force performance index to determine the anchoring characteristics of the anchor bolt. At present, there is no overall pull-out test device for the anchor bolt in my country. The bolt body can be cut into short sections, and the universal material testing machine can be used for testing, which cannot accurately simulate the current situation in the mine, and the labor intensity and low test accuracy are high during the test process.
