The concrete-based compression testing machine provided by the invention is characterized in that a mainframe box is arranged on one side of a connecting frame 1, and a protection plate 6 is just positioned between the mainframe box and the connecting frame 1; the protection plate 6 is solid and has a larger length, so that the protection plate can always keep a better protection state without being detached; and because the protection plate 6 is of a solid structure, the protection plate can fully block concrete which is collapsed in the detection process, and plays a role in protecting the mainframe box.
In the detection process, if protection is not needed, for example, the concrete block is small and is not easy to break up, the protective net 7 is rotated to connect the protective net 7 with the first positioning mechanism, so that the space between the bottom of the pressing plate 5 and the top of the support platform 2 is in an exposed state, the concrete block is convenient to put in and take out, and the support platform 2 after the test is finished is cleaned; however, if a large concrete block needs to be tested, the protective net 7 is rotated to connect the protective net 7 with the second positioning mechanism, so that the protective function can be achieved; when taking out the test piece, only need rotate the protection network 7 of certain side once more and be connected with first positioning mechanism, later take out the concrete piece, to a supporting bench 2 clear up can, simple and convenient.
The mainframe box, the connecting frame 1, the supporting table 2, the power table 3 and the like are the same as those of a concrete testing machine in the current market, and the internal structure and the working principle of the mainframe box are not described in detail herein, so that the understanding and implementation of the scheme of the application by the technical personnel in the field are not affected. In another embodiment, an oil cylinder is arranged above the power platform 3, the oil cylinder drives the power rod 4 to move downwards during detection, and a pressure sensor is arranged below the pressure applying plate 5 and used for sensing the pressure value of the concrete and then transmitting the pressure value out for recording.
When the protective net 7 is rotated upwards and the worker rotates to approach the first positioning body 10, the worker rotates the positioning rod 11 upwards to enable the positioning rod 11 to bypass the first positioning body 10, then (when the limiting plate 14 abuts against the outside of the connecting frame 1), the positioning rod 11 is released, the positioning rod 11 rotates downwards under the elastic force of the elastic piece 12 (namely a spring), the positioning rod 11 is clamped into the first positioning body 10, and the elastic piece 12 is still in an extending state at the moment; under the action of the elastic force of the elastic piece 12, the positioning rod 11 can be stably clamped in the first positioning body 10, so that the position of the positioning rod 11 can be stably maintained under the limiting action of the first positioning body 10 and the connecting frame 1, and meanwhile, the positioning rod 11 can support the protective net 7, so that the protective net 7 cannot turn downwards; moreover, even if the protection net 7 is not used all the time, the position of the protection net 7 can be stably kept in an upward state, and the stability is good.
Similarly, when the protective net 7 is used, the positioning rod 11 only needs to be rotated downwards, and then the positioning rod 11 is clamped between the second positioning body 17 and the connecting frame 1, so that the operation is simple and convenient; in addition, even if some concrete blocks hit the inner wall of the protection net 7 during the whole protection process, the second positioning bodies 17 can stably engage with the positioning rods 11 in the horizontal direction, so that the positions of the positioning rods 11 can be stably maintained, and the positional stability of the protection net 7 can be well maintained.
In the using process of the protective net 7, whether the protective net 7 is used or not can be selected according to the actual using condition, so that the application range is wider firstly; meanwhile, the protective net 7 is hinged on the connecting frame 1, so that the protective net 7 does not need to be disassembled even if not used, and the using effect is better.
Furthermore, since the driving rod 11b is rotatably connected to the connecting cylinder 11a, the connecting cylinder 11a can normally rotate (the connecting cylinder 11a is hinged to the protection net 7) and can support the driving rod 11b to rotate; like this the workman when rotating protection network 7 through actuating lever 11b, can be better prevent to take place relative rotation between actuating lever 11b and the palm, promptly after the workman holds between the fingers actuating lever 11b, can directly upwards or rotate protection network 7 downwards, at this in-process, actuating lever 11b can not take place relative rotation with between the palm, has improved use comfort to and safety in utilization (prevent that the palm from being rubbed injured). Meanwhile, the first guide part 18 and the second guide part 19 are arranged, so that when the driving rod 11b is connected with the first positioning body 10, the driving rod 11b can directly rotate under the shape of the first guide part 18, and meanwhile, the first guide part 18 can also drive the connecting cylinder 11a to rotate, so that the driving rod 11b can still be clamped between the first positioning body 10 and the connecting frame 1 even if a worker does not operate the positioning rod 11; likewise, the second guide 19 can directly transition the drive rod 11b between the second positioning body 17 and the connecting bracket 1.
When the limiting plates 14 on the two sides of the protective net 7 are used, the connecting cylinders 11a and the elastic pieces 12 are attached to the inner walls of the limiting plates 14, so that the limiting plates 14 can improve the stability of the positions of the connecting cylinders 11a and the elastic pieces 12, and can better protect the elastic pieces 12, namely, the elastic pieces 12 are prevented from being bent to the outside of the abdicating groove 13; meanwhile, in the using process, when the protective net 7 is subjected to external acting force, the connecting cylinders 11a can transmit the acting force to the limiting plate 14, so that the hinged positions of the connecting cylinders 11a and the protective net 7 can be protected, the position stability of the connecting cylinders 11a is prolonged, and meanwhile, the connecting cylinders have longer service lives.
The effect of terminating board 15 is, when the workman manually rotates actuating lever 11b, when rotating to the maximum angle on, actuating lever 11b this moment can cross first locating body 10 or second locating body 17, and terminating board 15 has restricted connecting cylinder 11a further to rotate simultaneously, so can prevent that elastic component 12 from taking place too big deformation, has prolonged the life of elastic component 12.
The cleaning pad 20 on top of the support bench 2 is completely attached to the top of the bench 2 so that it does not affect the normal performance of the test in the first place (i.e. it does not affect the maximum pressure that the concrete block can withstand when it is being fractured); then, after the test is finished, workers can directly clean the cleaning base plate 20, and the cleaning can be carried out through the opening of the anti-falling part 21; or the cleaning base plate 20 can be directly upwards taken down from the support table 2, and then the whole cleaning base plate 20 is taken out for cleaning, so that the cleaning effect is better, and the cleaning convenience is higher. Wherein, the opening of the anti-falling part 21 can be more simply and conveniently carried out when the concrete block is put in; and the falling prevention part 21 can prevent the chips from falling below the support table 2, and can also play a role in blocking the concrete blocks which are collapsed out, so that the protection effect is better.
