Automatic point taking device of resiliometer

Abstract

The invention discloses an automatic point taking device for a resiliometer, and belongs to the field of quality detection. The automatic point taking device comprises a lifting cart, a push rod is arranged at one side of the lifting cart, a longitudinal electric sliding rail and a cross beam clamping device are arranged at the top of the lifting cart, a transverse electric sliding rail is arranged at the top of the longitudinal electric sliding rail, an electric rotating disc is arranged at the top of the transverse electric sliding rail, a rotating table is rotationally connected to the top of the electric rotating disc, the resiliometer, a square seal, a guide pipe, a drill bit clamp and a distance measuring camera are arranged on the four faces of the rotating table correspondingly, the drill bit clamp is fixedly connected to the top of the rotating table, and a peristaltic pump is arranged at one side of the drill bit clamp; the input end of the peristaltic pump is communicated with the drill bit clamp, the output end of the peristaltic pump is communicated with a liquid conveying pipe, the liquid conveying pipe penetrates through the rotating table and is inserted into the guide pipe, efficient automatic point taking of the resiliometer can be achieved, concrete carbonization can be detected, and meanwhile, the device has a simpler and more convenient structure.

Description

technical field [0001] The invention relates to the field of quality inspection, and more specifically relates to an automatic point-taking device for a rebound hammer. Background technique [0002] The basic principle of the rebound tester is to use a spring to drive the heavy hammer, and the heavy hammer hits the bullet rod in vertical contact with the concrete surface with constant kinetic energy, so that the local concrete deforms and absorbs part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer , when all the kinetic energy of the rebound is converted into potential energy, the weight rebounds to the maximum distance, and the instrument displays the maximum rebound distance of the weight in the name of the rebound value. [0003] In order to measure the strength value of concrete, it is the maximum stress that concrete can bear under a certain stress state and working conditions. In order to accurately meas...

Problems solved by technology

[0004] However, when engineering personnel measure the concrete compressive strength of load-bearing beams in the construction site building, since the load-bearing beams are all located at high altitudes, the work is difficult and there are potential safety hazards. The special spring will exert a reaction force on the construction personnel and directly act on the ladder, which will aggravate the safety hazard
