Technical field
The utility model relates to building materials detection field, particularly a kind of reinforcing bar anti-bending strength detecting device.
Background technology
Anti-bending strength is one of leading indicator of steel bar quality, for this reason, detects at some reinforcing bar production units, reinforcing bar applying unit, reinforcing bar the beam test that unit etc. all will carry out reinforcing bar.Existing a kind of reinforcing bar beam test instrument comprises chamber, and the one end in chamber is provided with two reinforcing bar registration rollers, is provided with index dial, index dial has groove between two reinforcing bar registration rollers.The other end in chamber is provided with telescopic drive, and telescopic drive has driving stem, and driving stem is vertical with the line direction of two reinforcing bar registration rollers, and driving stem points between two reinforcing bar registration rollers.During above-mentioned reinforcing bar beam test instrument test, reinforcing bar sample is placed on the side of two reinforcing bar registration rollers towards telescopic drive, open telescopic drive, the end of the driving stem of telescopic drive withstands on reinforcing bar sample, make bar bending arrive certain degree, estimated roughly the anti-bending strength of reinforcing bar sample by the scale size read on index dial.
Above-mentioned reinforcing bar beam test instrument is in process of the test, what adopt is the force way that the end of the driving stem of telescopic drive withstands on reinforcing bar sample, because most reinforcing bar sample is columniform, in the process of top pressing reinforcing sample, easily get off from landing reinforcing bar sample in the top of driving stem, therefore the degree of crook of reinforcing bar sample is difficult to control in operation, often easily makes reinforcing bar sample curved transitions or bending not in place, affect test findings, and security performance reduces greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of reinforcing bar anti-bending strength detecting device, and the degree of crook of this reinforcing bar anti-bending strength detecting device reinforcing bar sample in operation easily controls, and testing result accuracy is reliable.
The technical solution of the utility model:
A kind of reinforcing bar anti-bending strength detecting device, comprise worktable and be arranged at the drive unit of one end on described worktable, the described worktable other end is also provided with two reinforcing bar registration rollers and the index dial between these two reinforcing bar registration rollers, described index dial has groove, described drive unit has driving stem, the free end of described driving stem is provided with the hook for catching on reinforcing bar, and the direction of described driving stem is vertical with the line direction of two reinforcing bar registration rollers.
Aforesaid reinforcing bar anti-bending strength detecting device, described index dial is positioned at described central point and is provided with projection for limiting reinforcing bar sample displacement.
Aforesaid reinforcing bar anti-bending strength detecting device, described index dial is circular or semicircle, and described groove is circular radial direction.
Aforesaid reinforcing bar anti-bending strength detecting device, the axis at described driving stem place is through the center of described index dial.
Compared with prior art, reinforcing bar anti-bending strength detecting device of the present utility model arranges hook due to the free end of hydraulic stem, by the mode of tension and compression, reinforcing bar sample is bent, the phenomenon that hydraulic stem gets off from landing reinforcing bar sample would not be there is, while improving test degree of accuracy, substantially increase security performance.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.At this, illustrative examples of the present utility model and explanation for explaining the utility model, but can not be thought restriction of the present utility model.
Embodiment.Reinforcing bar anti-bending strength detecting device, its structural drawing is as shown in Fig. 1 Fig. 2, and wherein, Fig. 1 is the structural representation of the utility model reinforcing bar anti-bending strength detecting device; Fig. 2 is that reinforcing bar sample is by the structural representation after stretch bending, with reference to Fig. 1 or Fig. 2, this reinforcing bar anti-bending strength detecting device comprises worktable 1, and worktable 1 one end is provided with two reinforcing bar registration rollers 2 and index dial 5, index dial 5, between two reinforcing bar registration rollers 2, index dial 5 has groove 6.
The other end of worktable 1 is provided with drive unit 3, drive unit 3 has driving stem 4, driving stem 4 points between two reinforcing bar registration rollers 2, and direction is vertical with the line direction of two reinforcing bar registration rollers 2, and the free end of driving stem 4 is provided with hook 10, this hook 10 is for catching on reinforcing bar 7, when carrying out reinforcing bar beam test, hook 10 catches on reinforcing bar 7, and drive unit 3 drives driving stem 4 to shrink, reinforcing bar 7 is pulled to buckle, as shown in Figure 2.
In the present embodiment, the other end of worktable 1 is also provided with position transducer 8 and force snesor 9, and wherein, position transducer 8 is connected with index dial 5 and drive unit respectively, and force snesor 9 is connected with drive unit 3.
In the present embodiment, index dial 5 is circular or semicircle, and groove 6 is circular radial direction, and the central point of index dial 5 is positioned on the axis at driving stem 4 place.Certainly, according to actual conditions, described index dial 5 can also be made into other shape, here will not enumerate.
In order to position transducer 8 accurately can detect the position of reinforcing bar 7, index dial 5 is positioned at described central point and is provided with projection 11 for limiting reinforcing bar sample displacement.
Above-mentioned reinforcing bar anti-bending strength sensors work process is such, first reinforcing bar 7 to be measured is placed on two reinforcing bar registration rollers 2, the hook 10 of driving stem 4 is caught on reinforcing bar 7, by the mode of tension and compression, reinforcing bar sample is bent, the phenomenon that driving stem 4 gets off from landing reinforcing bar sample would not be there is, while improving test degree of accuracy, substantially increase security performance.Now drive unit 3 is started working, driving stem 4 is driven to shrink, reinforcing bar 7 is pulled to buckle, until become curved after the tip contact of bend of reinforcing bar to protruding 11, now position transducer position transducer 8 detects this position, accessory drive 3 quits work, now force snesor 9 detects pulling force size and is shown by this pulling force, this pulling force is labeled as F, the reinforcing bar sample flexibility now index dial shown is N, the anti-bending strength of reinforcing bar sample is drawn by calculating F and N proportionate relationship therebetween
In sum, reinforcing bar anti-bending strength detecting device of the present utility model arranges hook due to the free end of driving stem, by the mode of tension and compression, reinforcing bar sample is bent, the phenomenon that driving stem gets off from landing reinforcing bar sample would not be there is, test degree of accuracy can not only be improved, the security performance of test can also be improved.Simultaneously, because the central spot of index dial is on the axis at hydraulic stem place, reinforcing bar sample is by after stretch bending, when the tip contact of bend is to when being positioned at central spot protruding of index dial, position transducer detects this position, accessory drive quits work, now force snesor detects pulling force size and is shown by this pulling force, the anti-bending strength of reinforcing bar sample is drawn by the reinforcing bar sample flexibility size proportionate relationship therebetween that pulling force size and index dial show, will draw very accurate experimental data like this, test findings accurately and reliably.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
