Description
Technical field
The utility model relates to a kind of engineering survey equipment technical field, particularly relates to a kind of reisilometer.
Background technology
The ultimate principle of reisilometer uses Spring driving weight, weight clashes into the elastic stem with concrete surface perpendicular contact with constant kinetic energy, local concrete is made to deform and absorb part energy, another part Conversion of Energy is the bounce-back kinetic energy of weight, when the kinetic energy that rebounds all changes into potential energy, weight bounce-back reaches ultimate range, and the maximum bounce-back distance of weight shows with the name of the rebound value ratio of spring initial length (the maximum bounce-back distance with) by instrument.Meet the M225 type reisilometer of JGJ/T23-2011 technical regulation for detecting the concrete compressive strength within the scope of 10-60Mpa, system standard energy is 2.207J, and indicating value system is the direct reading medium-sized reisilometer of pointer and is supervised by chief editor unit-Shaanxi Prov. Building Science Research and Design Inst. of national metrological verification regulations " concrete bouncing back instrument " (JJG817-93) and industry standard " concrete intensity with rebound method technical regulation ".Concrete bouncing back instrument, in order to test concrete compressive strength, is the nondestructive detecting instrument of concrete crushing strength the most widely of Site Detection.This be obtain concrete quality and intensity the most fast, the simplest and the most most economical method of testing.
One when attack detects, and it is motionless that indicator slide block is parked in reference position: 1. pointer spring leaf fractures, and at this moment spring leaf does not hang elastic hammer in the process of elastic hammer attack, makes indicator slide block be parked in reference position motionless.Method for maintaining: change spring leaf.The take-off position of elastic hammer is defective, causes indicator slide block to be parked in reference position motionless.Method for maintaining: the position of box nut after adjustment, and make the unhook position of elastic hammer reach 100 grooves.The pointer segment of indicator slide block is too little relative to the subtended angle of needle pivot, and at this moment pointer segment friction force in the process of elastic hammer attack is too little, and pointer can not be slided.Should pointer part be unloaded, suitably pull large angle, make it in specialized range.
Current existing reisilometer complex structure, be inconvenient to keep in repair, serviceable life is shorter.
