Electromagnetic power concrete quality detection resiliometer device

Abstract

The invention provides an electromagnetic power concrete quality detection resiliometer device. The electromagnetic power concrete quality detection resiliometer device comprises a shell, an electromagnetic power device and a resilience indicating value mechanism which are mounted in the shell, and a handle mounted outside the shell, the resilience indicating value mechanism comprises a resilience mechanism and an indicating value mechanism, and the electromagnetic power device comprises a coil, a fixed iron core, a movable iron core and an adjusting nut. When the coil of the fixed iron core is electrified, an electromagnetic effect is generated to attract the movable iron core, the pull rod is inserted into the central guide rod and connected with an elastic striking rod, and the pull rod drives the elastic striking rod and an elastic striking hammer to a test launching position when the movable iron core is attracted, so that quick return is realized. According to the electromagnetic power concrete quality detection resiliometer device, the elastic striking hammer is rapidly reset in an electromagnetic power mode, the function of continuously launching the elastic striking rod can be achieved, manual work is not completely relied on, the labor intensity of workers is reduced, and the apparatus is accurate in operation positioning and good in safety.

Description

technical field [0001] The invention relates to a non-destructive detection technology of concrete structure quality, in particular to an electromagnetic dynamic concrete quality detection rebound hammer device. Background technique [0002] Concrete rebound tester is a testing device, suitable for testing the strength of general building components, bridges and various concrete components (slabs, beams, columns, bridges), the main technical indicators are impact function; Hammer stroke; the maximum static friction of the pointer system and the average value of the steel drill rate. [0003] The working principle of the concrete rebound tester is to use a spring to drive the bounce hammer and use the recovery force of the instantaneous elastic deformation generated by the bounce rod to hit the concrete surface, so that the bounce hammer drives the pointer to bounce back and indicates the distance of the bounce. The ratio of the rebound distance to the distance between the b...
