一种锚杆拉拔实验用辅助设备及实验仪Auxiliary equipment and experimental instrument for bolt pulling experiment

技术领域technical field

本发明涉及拉拔设备技术领域，具体涉及一种锚杆拉拔实验用辅助设备及实验仪。The invention relates to the technical field of drawing equipment, in particular to an auxiliary equipment and an experimental instrument for an anchor rod drawing experiment.

背景技术Background technique

锚杆拉拔实验仪主要被用来检测各种锚杆、钢筋等锚杆的锚固力。锚杆拉拔仪由手动泵、液压缸、智能数显压力表、带快速接头的高压油管、锚具和手提便携箱组成。The bolt pulling tester is mainly used to detect the anchoring force of various bolts, steel bars and other bolts. The bolt puller is composed of a manual pump, a hydraulic cylinder, an intelligent digital pressure gauge, a high-pressure oil pipe with a quick connector, an anchor and a portable carrying case.

现有市面所见及所用锚杆拉拔仪多用于现场锚杆检测，其检测时锚杆已锚固于岩体中且预留一定的长度。室内锚杆拉拔检测时，多用混凝土模拟岩体，将锚杆埋置于混凝土中形成锚杆。采用现场锚杆拉拔仪则需将锚杆做得足够大，需消耗大量的人力、物力及财力；用拉力机检测锚杆锚固性能则简单、高效、精准，唯一不足是拉力机上、下钳口与锚杆之间的衔接一直是困扰研究人员的一大难题。Most of the bolt pullers seen and used in the market are used for on-site bolt detection. When the bolt is detected, the bolt has been anchored in the rock mass and a certain length is reserved. In the indoor bolt pull-out detection, concrete is often used to simulate the rock mass, and the bolt is embedded in the concrete to form the bolt. Using the on-site bolt puller needs to make the bolt large enough, which consumes a lot of manpower, material resources and financial resources; it is simple, efficient and accurate to use the tensile machine to detect the anchoring performance of the bolt. The only disadvantage is that the upper and lower clamps of the tensile machine The connection between the mouth and the anchor has always been a big problem for researchers.
