Description
Technical field
The present invention relates to a kind of reisilometer, especially a kind of reisilometer with sensor assembly.
Background technology
Reisilometer belongs to construction work detection type instrument, is mainly used in non-damaged detection of the normal concrete compressive strength in the concrete structure engineering.The tradition reisilometer is mechanical type reisilometer (Fig. 1).Mainly be to drive elastic hammer and the restoring force of the instantaneous elasticity distortion that produced through elastic stem attack concrete surface, make elastic hammer drive pointer and rebound and indicate the distance of rebounding with spring.As one of relevant index of concrete crushing strength, infer concrete compressive strength with rebound value.
Publication number is that the one Chinese patent application of CN2379797A discloses a kind of high-strength concrete and surveys strong reisilometer; Comprise long column shape appearance shell, the telescopic elastic stem in appearance shell front port place, the elastic tension spring that is connected with centre pilot, the ram hammer that on centre pilot, slides, ram hammer front end that elastic stem is slidingly connected, the guide flange of ram hammer rear end and elastic hook, button and the indicator slide block corresponding with guide flange.
For this class mechanical type reisilometer, because after each attack, the user need artificial read top registration and note, therefore, present digital display reisilometer all is on the basis of mechanical reisilometer, to load various sensors, to realize the reading rebound value function automatically.Existing all kinds of digital display reisilometer fixation of sensor all are that mechanical reisilometer casing is reequiped the installation of carrying out sensor and fixing to the method on the mechanical reisilometer on the market.But there are some shortcomings in these repacking modes.For example, because mechanical reisilometer is a matured product, if casing is reequiped; Just need carry out mould to casing revises; This just requires digital display reisilometer research and development enterprise is former mechanical reisilometer producer or other research and development enterprise to former mechanical reisilometer producer customization casing, has so just caused the research and development threshold higher, and casing has been carried out mould revise; Cost is higher, is unfavorable for the penetration and promotion of digital display reisilometer.For another example, because impact is bigger in the reisilometer attack process, mechanical reisilometer parts and Sensor section damage easily; Need often maintenance to change; The mode of existing this fixation of sensor can't satisfy this easy replacing, be prone to the requirement of installing/dismounting operation, in case serious fault appears in sensor or mechanical part, the user must return the maintenance of former factory with digital display reisilometer complete machine; Use inconvenience, increased maintenance cost greatly.And for example, the sensor of installing on the existing mechanical reisilometer all is that damping ratio is bigger mostly; Promptly increased the friction (Fig. 1) of the pointer blocks of former mechanical reisilometer virtually; Therefore, need the friction of whole adjustment pointer blocks, otherwise can influence the accuracy of measurement result.
