Description
Technical field
The utility model belongs to mining engineering technical field, relates to a kind of bar-mat reinforcement dynamic mechanical proving installation.
Background technology
Bar-mat reinforcement is formed by colligation or welding production by the right-angled intersection of vertical and horizontal reinforcing bar, in netted supporting construction, in deep underground excavation engineering and protection works, is used widely in the remedy and treatment of especially rock burst.But, the examination of bar-mat reinforcement dynamic performance is surveyed, also be there is no corresponding equipment means.From document both domestic and external, evaluation for bar-mat reinforcement dynamic performance mainly utilizes reinforcing bar dynamic performance, pad dynamics and reticulate texture dynamic characteristic to evaluate, and does not directly test the stressed and energy-absorbing effect of bar-mat reinforcement under the fast rock impact condition of reinforcing bar net height.
Utility model content
The purpose of this utility model is to provide a kind of bar-mat reinforcement dynamic mechanical proving installation, directly can measure the dynamic mechanical of bar-mat reinforcement.
The technical scheme that the utility model adopts is: a kind of bar-mat reinforcement dynamic mechanical proving installation, comprise the framework with four supporting legs, frame roof is provided with high-speed camera a, high-speed camera a is connected with trigger by data line, trigger lower end hangs with drops hammer, also comprise bar-mat reinforcement, bar-mat reinforcement is fixed on four supporting legs of framework, bar-mat reinforcement bottom surface is provided with high-speed camera b, and high-speed camera b, trigger are connected with Data Acquisition and Conversion System (DACS) by data line with high-speed camera a.
Feature of the present utility model is also:
High-speed camera a is vertically arranged.
High-speed camera b is horizontally disposed with.
High-speed camera a is arranged on the center of frame roof.
High-speed camera b is arranged on bar-mat reinforcement bottom surface near any supporting leg place of framework.
Data Acquisition and Conversion System (DACS) is made up of computing machine, data collecting card and EDC controller.
The beneficial effects of the utility model are: a kind of bar-mat reinforcement dynamic mechanical of the utility model proving installation, Data Acquisition and Conversion System (DACS) driving is dropped hammer and is risen and fallen, and also controls also vertical high-speed camera simultaneously and takes the overall process (vertical visual angle) of the shock bar-mat reinforcement that drops hammer and drop hammer; Taken the overall process (level is to visual angle) of the shock bar-mat reinforcement that drops hammer and drop hammer to high-speed camera by level.Before can obtaining by regulating weight of dropping hammer clashing into, different energy drops hammer, the distortion of bar-mat reinforcement after record different-energy drops hammer and clashes into, destructive characteristics, and then the dynamic performance of assay bar-mat reinforcement.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bar-mat reinforcement dynamic mechanical of the utility model proving installation.
In figure, 1. framework, 2. drops hammer, 3. trigger, 4. high-speed camera a, 5. bar-mat reinforcement, 6. high-speed camera b, 7. Data Acquisition and Conversion System (DACS).
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of bar-mat reinforcement dynamic mechanical proving installation, as shown in Figure 1.Comprise the framework 1 with four supporting legs, framework 1 top is provided with high-speed camera a4, high-speed camera a4 is connected with trigger 3 by data line, trigger 3 lower end hangs with drops hammer 2, also comprise bar-mat reinforcement 5, bar-mat reinforcement 5 is fixed on four supporting legs of described framework 1, bar-mat reinforcement 5 bottom surface is provided with high-speed camera b6, high-speed camera b6, trigger 3 is connected with Data Acquisition and Conversion System (DACS) 7 by data line with high-speed camera a4, high-speed camera a4 is vertically arranged, described high-speed camera b6 is horizontally disposed with, high-speed camera a4 is arranged on the center at framework 1 top, high-speed camera b6 is arranged on bar-mat reinforcement 5 bottom surface near any supporting leg place of framework 1, Data Acquisition and Conversion System (DACS) 7 is by computing machine, data collecting card and EDC controller are formed.
During use, debugged by Data Acquisition and Conversion System (DACS) 7, make trigger 3, high-speed camera a4, high-speed camera b6 synchronous; Data Acquisition and Conversion System (DACS) 7 sends instruction to trigger 3, high-speed camera a4 and high-speed camera b6,2 whereabouts of dropping hammer, and high-speed camera a4 and high-speed camera b6 starts record simultaneously, until 2 stoppings of dropping hammer; According to drop hammer 2 quality, height of drop can calculate drop hammer 2 reach bar-mat reinforcement 5 time energy; According to the record of high-speed camera b6 can obtain dropping hammer 2 reach bar-mat reinforcement 5 time speed and bar-mat reinforcement in the vertical displacement data under 2 percussive actions of dropping hammer; Can be obtained dropping hammer according to the record of high-speed camera a4 the distortion of bar-mat reinforcement after 2 shock bar-mat reinforcements 5; If bar-mat reinforcement 2 does not destroy, increase drop hammer 2 quality, until bar-mat reinforcement 5 is out of shape.
A kind of bar-mat reinforcement dynamic mechanical of the utility model proving installation, Data Acquisition and Conversion System (DACS) driving is dropped hammer and is risen and fallen, and also controls also vertical high-speed camera simultaneously and takes the overall process (vertical visual angle) of the shock bar-mat reinforcement that drops hammer and drop hammer; Taken the overall process (level is to visual angle) of the shock bar-mat reinforcement that drops hammer and drop hammer to high-speed camera by level.Before can obtaining by regulating weight of dropping hammer clashing into, different energy drops hammer, the distortion of bar-mat reinforcement after record different-energy drops hammer and clashes into, destructive characteristics, and then the dynamic performance of assay bar-mat reinforcement.In addition, this apparatus structure is simple, and cost is low, easy to operate, is easy to promote.
