Embodiment Construction

[0026] like figure 1 As shown, the present invention provides a kind of self-generating hammer, including hammer 1 and its measurement circuit, and the innovative part of the present invention is:

[0027] a. Two guide rail brackets 4 and a spring 5 are set on the Hammer 1. A guide rod 3 for sliding fit is set in the guide rail bracket 4. One side of the guide rod 3 is provided with a section of rack 3a, and the guide rod 3 extends back The part of the hammer 1 is basically flush with the end of the shooting rod 2 , the left end of the spring 5 is fixedly connected to the shell of the rebound hammer 1 , and the right end is connected to the right end of the guide rod 3 .

[0028] b. A gear set consisting of a pinion 11, a large gear 10, and a micro-generator 8 are arranged in the Hammer 1. The pinion 11 in the gear set forms a meshing transmission with the rack 3a on the guide rod 3, The large gear 10 in the gear set meshes with the pinion 9 connected to the output shaft of t...

Abstract

The invention relates to a self-generating resiliometer, which is characterized in that: (a) a guide rail bracket (4) and a spring (5) are arranged on a resiliometer (1), a guide rod (3) with a rack (3a) is arranged in the guide rail bracket (4), the left end of the spring (5) is fixedly connected to a resiliometer shell and the right end of the spring (5) is connected to the guide rod (3); (b) apinion (11) and a large gear (10) are arranged in the resiliometer (1), the pinion (11) is in meshing transmission with the rack (3a), and the large gear (10) is in meshing transmission with a pinion(9) connected on an output shaft of a generator (8) and drives the generator to generate electricity; and (c) a bridge rectifier circuit, an energy storage element and a power supply management circuit are arranged in the resiliometer and the power supply management circuit is connected with the measuring circuit. Compared with the prior art, the self-generating resiliometer has the advantages of(1) having stored energy without being connected with a commercial power, (2) having self-generating function without being charged frequently, and (3) adopting a low power consumption circuit, beingfree from maintenance for a long time and the like.

Description

technical field [0001] The invention relates to a geotechnical measuring device, in particular to a rebound tester for measuring the compressive strength of concrete. Background technique [0002] The concrete hammer is the restoring force of the instantaneous elastic deformation produced by a spring-driven hammer and hitting the concrete surface through the hammer, so that the hammer drives the marking slider to rebound and indicates the rebound distance. The rebound value (the ratio of the rebound distance to the distance between the hammer and the striker before impact, calculated as a percentage) is used as one of the indicators related to the compressive strength of concrete to estimate the compressive strength of concrete. The rebound value actually reflects the surface hardness of the concrete. [0003] There are two types of hammer hammers, mechanical and electronic. The mechanical hammer needs manual reading, recording, statistics, calculation, printing and other o...
