Abstract

The invention relates to the field of anchor rod drawing and in particular relates to an electromagnetic induction drawing instrument. According to the electromagnetic induction drawing instrument provided by the invention, two groups of electromagnetic induction drawing assemblies are arranged at the outer part of an anchor rod; an anchorage device is arranged at a part, located at the outer sides of the two groups of electromagnetic induction drawing assemblies, of the anchor rod and is used for limiting and fixing; corresponding thread through holes are opened and a limiting screw rod is used for fixing, so that the positions of the electromagnetic induction drawing assemblies are conveniently limited; electromagnet assemblies arranged in mounting shell bodies and are electrically connected with a power supply device so that a magnetic force is generated; the electromagnet assemblies are arranged oppositely and the two groups of electromagnetic induction drawing assemblies move oppositely, so that the anchor rod is drawn; an elastic buffering assembly composed of a limiting mounting plate and an elastic force buffering cushion is arranged at one side, close to a concrete building block or the anchorage device, of each mounting shell body and is used for buffering, so that damages to the electromagnetic induction drawing assemblies are avoided and the electromagnetic induction drawing instrument is convenient for people to use.

Description

technical field [0001] The invention relates to the field of bolt drawing, in particular to an electromagnetic induction drawing instrument. Background technique [0002] The puller is suitable for on-site testing of the anchoring force of various anchor rods, steel bars and other anchors, and is a necessary on-site testing instrument for every engineering quality testing unit. [0003] At present, the commonly used drawing instrument is composed of hydraulic cylinder, manual pump, pressure gauge, high pressure oil pipe, anchorage and so on. During on-site inspection, the hydraulic cylinder must be placed on the anchor rod or steel bar, the anchor is fixed, the hydraulic cylinder is connected to the manual pump with a high-pressure oil pipe, and then the manual pump is used to pressurize. This drawing instrument is the most commonly used, but the instrument is heavy, and the anti-wear hydraulic oil used in the drawing instrument has different consistency under different amb...
