The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] The present invention provides a double-detection cavity concrete compressive strength detection device through improvement. Figure 1-Figure 6 As shown, it includes a working box 1 and a supporting seat 18, four fixing plates 2 are welded on the inner wall at the bottom of the working box 1, and a fixing bolt 3 is threadedly connected at the center of the outer wall of one side of the fixing plate 2, one end of the fixing bolt 3 located between the two fixing plates 2 is rotatably connected to a bearing seat 5, and an extrusion plate 6 is welded on the outer wall of the other side of the bearing seat 5 away from the fixing bolt 3, and a hand wheel 4 is welded on the other end of the fixing bolt 3 away from the extrusion plate 6, a slide groove 14 is provided at the bottom of the outer wall of the adjacent side of two laterally adjacent fixing plates 2, and the slide groove 14 is distributed in an L-shaped structure, and a movable rod 15 is slidably connected inside the slide groove 14, and a brush 16 is welded on the outer wall at the bottom of the movable rod 15, and the two extrusion plates 6 move toward the concrete test block at the same time to clamp it, so as to fix the concrete test block and avoid the concrete test block from slipping during the detection process, thereby improving the stability of the device, and at the same time, the sliding rod 15 drives the brush 16 to slide inside the slide groove 14, so that the brush 16 moves on the supporting plate, and can clean the debris on the supporting plate.

[0033] Furthermore, a handle 17 is welded at the center of the front outer wall of the movable rod 15, and a debris groove 26 is welded at the bottom of the front outer wall of the working box 1 and the bottom of the outer wall on the other side away from the front outer wall, which can collect the debris cleaned by the brush 16 and then drop it into the collection box 24, making it more convenient to use.

[0034] Furthermore, a collecting box 24 is welded on the outer wall of the bottom of the working box 1, and through grooves 23 connected to the collecting box 24 are opened on the bottom inner walls on both sides of the working box 1. The flying chips inside the working box 12 fall into the collecting box 24 through the through grooves 23 for collection, thereby improving the practicability of the device.

[0035] Furthermore, a movable door 25 is movably connected to the outer wall of the front side of the collection box 24 via a hinge, and a handle is welded to the bottom of the outer wall of the front side of the movable door 25, so that the waste collected in the collection box 24 can be easily taken out.

[0036] Furthermore, the working box 1 is located on the bottom inner wall between the two fixed plates 2, and is respectively connected with a first support plate 7 and a second support plate 8 by hinges, and the second support plate 8 is distributed in a concave shape. The first support plate 7 and the second support plate 8 are provided with a pull groove 28 on the outer wall on one side of the top, so that the first support plate 7 and the second support plate 8 can be pulled up to clean the concrete fragments on their surfaces into the debris groove 26.

[0037] Furthermore, a hydraulic cylinder 9 is installed at the center of the top outer wall of the working box 1 by bolts, and a hydraulic rod 10 located inside the working box 1 is movably connected to the outer wall at the bottom of the hydraulic cylinder 9. The hydraulic cylinder 10 applies pressure to the hydraulic rod 10, so that the pressing block moves up and down, thereby testing the concrete test block.

[0038] Furthermore, a transverse plate 11 is welded to the bottom end of the hydraulic rod 10, a first pressure block 12 is welded to the bottom outer wall of the transverse plate 11 directly above the first support plate 7, and a second pressure block 13 with a concave structure distribution is welded to the bottom outer wall of the transverse plate 11 on the other side away from the first pressure block 12. The second pressure block 13 and the second support plate 8 are both concave structures, which can distribute pressure to the surrounding center of the concrete test block and conduct multi-directional detection to make the detection result more comprehensive.

[0039] Furthermore, a shock-absorbing cylinder 19 with an equidistant structure is welded to the top outer wall of the support seat 18, a movable block 20 is slidably connected to the inside of the shock-absorbing cylinder 19, and a support column 21 connected to the bottom of the working box 1 is welded to the top outer wall of the movable block 20, a shock-absorbing spring 22 is welded to the outer wall of the bottom of the movable block 20, and the support column 21 is movably connected to the inside of the shock-absorbing cylinder 19 through the shock-absorbing spring 22. The telescopic force of the shock-absorbing spring 22 can reduce the impact force on the device during pressure detection, thereby having a protective buffering effect on the device.

[0040] Furthermore, both sides of the outer wall on the front of the working box 1 and both sides away from the outer wall on the front are movably connected with a box door 27 through hinges, and both ends of the outer wall at the bottom of the support seat 18 are equipped with universal wheels 29 through bolts. Closing the box door 27 can prevent flying chips from splashing and protect the surrounding environment.

[0041] The working principle of the present invention is as follows: the double-detection chamber concrete compressive strength detection device respectively places the concrete test block on the first support plate 7 and the second support plate 8, and at the same time, the fixing bolt 3 on the fixing plate 2 is screwed by the hand wheel 4. At this time, the two extrusion plates 6 move toward the concrete test block at the same time, so as to squeeze and fix the concrete test block, and avoid the concrete test block from sliding sideways and falling off the support plate during the detection process, thereby improving the stability of the device. Then, the box door 27 is closed, and the hydraulic cylinder 9 is started. The hydraulic cylinder 9 applies pressure to the hydraulic rod 10, driving the cross plate 11, the first pressing block 12 and the second pressing block 13 to press the concrete test block downward. When conducting the test, closing the box door 27 can prevent concrete debris from flying everywhere during the test and protect the surrounding working environment. The debris falls into the collection box 24 through the through slot 23 for collection. After the test is completed, open the box door 27, reversely turn the fixing bolt 3 to take out the concrete test block, pull the handle 17, and the movable rod 15 slides inside the slide slot 14, so that the brush 16 moves on the surface of the support plate to clean the debris on the surface of the support plate, which can prevent the debris from accumulating on the surface of the support plate and affecting the test result of the next concrete test block, thereby improving the accuracy of the device.

[0042] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
