[0002] During the construction process, the quality of concrete plays a critical role in the quality of engineering construction. Therefore, testers usually collect cement concrete samples at the construction site for cement strength testing, including flexural strength testing, etc. However, there are some defects in the construction cement strength testing device in the prior art: in the process of testing the flexural strength of the sample using the existing strength testing device, in order to prevent the cement bricks from being crushed and splashing out fragments, baffles and other enclosures are generally used to surround the cement bricks for protection. Each use requires assembly and disassembly of the baffles, which is cumbersome. Some automatic lifting enclosures are set from the operating table, and the automatic lifting enclosures extend or retract from the holes on the upper surface of the operating table. However, the splashed fragments and debris are easily stuck in these holes, thereby affecting the normal use of the automatic lifting enclosure, resulting in poor reliability of the automatic lifting enclosure.

[0038] See also Figures 1 to 11 The present invention provides a construction cement strength detection device, wherein the construction cement strength detection device comprises:

[0039] The operating table 1 may be provided with a support, a support 2 or a support foot or other structures below the operating table 1 so as to be placed (supported) on other workstations (desks) or on the ground through these structures, or may be directly placed (supported) on other workstations (desks) or on the ground without providing these structures;

[0040] A cement sample support mechanism, a bracket 100 and a telescopic driven pressure device 200 provided on the bracket 100 are provided on the operating table 1. The telescopic driven pressure device 200 comprises a pressure device body 201 connected to the bracket 100 and a telescopic member 202 telescopically connected to the pressure device body 201. A pressure element is connected to the end of the telescopic member 202. The telescopic direction of the telescopic member 202 is along the vertical direction so that the pressure element can move downward toward the cement sample support mechanism and upward away from the cement sample support mechanism.

[0041] A multi-layer enclosure is set on the operating table 1, and each enclosure is arranged around the cement sample supporting mechanism. The bottom layer of the multi-layer enclosure is fixedly set on the operating table 1, and each layer of enclosure on the bottom layer of the enclosure can be lifted and lowered on the corresponding lower layer of enclosure, and there are corresponding limit matching structures between the upper and lower adjacent enclosures, so that when the upper layer of the upper and lower adjacent enclosures rises to a predetermined distance relative to the lower layer of the enclosure and continues to rise, the upper layer of the enclosure can lift the lower layer of the enclosure through the limit matching structure.

[0042] Since in the construction cement strength detection device provided by the present invention, a plurality of layers of enclosures are arranged on the operating table 1, and the bottommost enclosure of the plurality of layers of enclosures is fixedly arranged on the operating table 1 instead of being passed through the operating table 1 up and down, there is no need to set holes on the operating table 1 for any enclosure to be lifted and lowered. When the cement sample on the cement sample support mechanism in the space surrounded by the plurality of layers of enclosures is pressed by the pressure device, there will be no problem of affecting the lifting and lowering of the enclosures due to splashing fragments and debris stuck in the holes, thereby improving the reliability of the plurality of layers of enclosures. Moreover, the layers of enclosures on the bottommost enclosure can be lifted and lowered on the corresponding lower enclosures. Each enclosure is lifted and lowered layer by layer (at this time, it is in the initial state), and corresponding limiting matching structures are provided between the upper and lower adjacent enclosures. By lifting the topmost enclosure, the lower enclosures can be driven to rise layer by layer subsequently. The plurality of layers of enclosures finally form a raised overall enclosure structure (thus being in an enclosure state), and the enclosure of the cement sample on the cement sample support mechanism is conveniently realized.

[0043] According to a preferred embodiment of the present application, a cement strength detection device for construction includes a traction mechanism, which is connected to a telescopic member 202 and an uppermost enclosure member among the multi-layer enclosure members, so that when the telescopic member 202 moves downward, the traction mechanism lifts the uppermost enclosure member among the multi-layer enclosure members upward. In this embodiment, when the telescopic member 202 moves downward, the traction mechanism lifts the uppermost enclosure member among the multi-layer enclosure members upward. Therefore, when the telescopic member 202 continuously descends and approaches the cement sample to be pressurized of the cement sample support mechanism, the lower-layer enclosure member can be lifted layer by layer through the upper-layer enclosure member through a limiting matching structure, so that when the pressure element performs a strength detection action (pressurization) on the cement sample, the multi-layer enclosure member finally forms an overall elevated enclosure structure, and the rise of the multi-layer enclosure member is achieved just by the descent of the telescopic member 202, and the multi-layer enclosure member can be lifted incidentally in the process of the pressure element moving downward toward the cement sample support mechanism without an additional lifting device.

[0044] According to other embodiments of the present application, the construction cement strength detection device includes a lifting device, which is connected to the topmost enclosure among the multi-layer enclosures so as to be able to lift the topmost enclosure among the multi-layer enclosures upwards, that is, the multi-layer enclosures can also be lifted by an additional independent lifting device.

[0045] According to a specific embodiment of the present application, the bottommost enclosure among the multi-layer enclosures is the first enclosure 300, and each layer of enclosures on the bottommost enclosure is the second enclosure 400. The multi-layer enclosure includes at least two layers of second enclosures 400, for example, three layers of second enclosures 400, plus the first enclosure 300, for a total of four layers of enclosures. Of course, the number of second enclosures 400 can be appropriately increased or decreased according to actual needs. The bottommost enclosure is a fixed enclosure, which can be fixedly connected to the operating table 1 by gluing, welding, threaded fasteners, etc. Each second enclosure 400 can be lifted up by the second enclosure 400 thereon and move upward, and descend by its own weight when the second enclosure 400 thereon descends.

[0046] See also Figures 1 to 8According to the first embodiment of the present application, the lower end of the first enclosure 300 is fixedly connected to the operating table 1, the inner side of the upper end of the first enclosure 300 (the side facing the cement sample supporting mechanism) has a first guide head 301, the outer side of the second enclosure 400 (the side facing away from the cement sample supporting mechanism) has a guide rail groove 401 arranged in the up-down direction, the inner side of the upper end of the second enclosure 400 (the side facing the cement sample supporting mechanism) has a second guide head 402, the upper end of the guide rail groove 401 ends at the upper retaining wall 403, and the lower end of the guide rail groove 401 ends at the upper retaining wall 403. The first guide head 301 can be relatively slidably disposed in the guide groove 401 of the second enclosure 400 of the lowest layer among at least two layers of second enclosures 400, and the second guide head 402 can be relatively slidably disposed in the guide groove 401 of the corresponding upper layer of second enclosure 400. When each second enclosure 400 is not subjected to external force, the upper retaining wall 403 corresponding to the guide groove 401 of the second enclosure 400 of the lowest layer among at least two layers of second enclosures 400 is supported on the upper surface of the first guide head 301, and the adjacent second enclosures 400 are The upper retaining wall 403 corresponding to the guide groove 401 of the upper second enclosure 400 supports the upper surface of the second guide head 402 of the lower second enclosure 400. When the upper second enclosure 400 of the adjacent second enclosure 400 rises relative to the lower second enclosure 400 until the lower retaining wall 404 of the upper second enclosure 400 blocks the lower end of the second guide head 402 of the lower second enclosure 400 and continues to rise, the upper second enclosure 400 can form a corresponding lower retaining wall 404 and the second guide head 402. The limiting cooperation structure lifts the second enclosure 400 at the lower layer. Preferably, when the pressure element applies pressure to the sample of the cement sample support mechanism, the second enclosure 400 at the lowermost layer among at least two layers of the second enclosure 400 is not completely lifted, that is, the lower retaining wall 404 of the second enclosure 400 at the lowermost layer among at least two layers of the second enclosure 400 has not yet hit the first guide head 301 at the upper end of the first enclosure 300. In this way, it can be ensured that when the pressure element breaks the cement sample and continues to move downward, the second enclosure 400 at the lowermost layer among the second enclosure 400 still has room to rise.

[0047] Specifically, a plurality of first guide heads 301 may be arranged axially along the first enclosure member 300 , and a plurality of guide rail grooves 401 and second guide heads 402 of the second enclosure member 400 may also be arranged correspondingly.

[0048] According to a preferred embodiment of the present application, the lower end of the second enclosure piece 400 of the lowest layer among at least two layers of second enclosure pieces 400 is provided with a brush piece 3 abutting against the inner side surface of the first enclosure piece 300, and the lower end of the second enclosure piece 400 of the upper layer among adjacent second enclosure pieces 400 is provided with a brush piece 3 abutting against the inner side surface of the second enclosure piece 400 of the lower layer. This facilitates the use of the brush piece 3 to clean possible dust and debris produced by the breakage of the cement sample adhering to the inner side surface of the second enclosure piece 400 of the lower layer when each second enclosure piece 400 is lowered, thereby ensuring the smoothness of the inner side surface of the second enclosure piece 400 and improving the reliability and stability of the lifting and lowering of the second enclosure piece 400.

[0049] See also Fig. 9According to the second embodiment of the present application, the lower end of the first enclosure member 300 is fixedly connected to the operating table 1, the inner side and / or outer side of the upper end of the first enclosure member 300 has a first protruding stopper 302, the second enclosure member 400 forms an inner groove 405 opening downward, and the lower end of the groove wall of the inner groove 405 forms a second protruding stopper 406, and the inner side (the side facing the cement sample supporting mechanism) and / or the outer side (the side facing away from the cement sample supporting mechanism) of the outer surface of the upper end of the second enclosure member 400 has a third protruding stopper 407, and the first protruding stopper 302, the second protruding stopper 406 and the third protruding stopper 407 are provided on the inner side (the side facing the cement sample supporting mechanism) and / or the outer side (the side facing away from the cement sample supporting mechanism). The stopper 407 is preferably a full-circle annular protrusion structure, and the second protruding stopper 406 in the inner groove 405 of the second enclosure 400 of the lowermost layer of at least two layers of second enclosures 400 is arranged correspondingly to the first protruding stopper 302, and the second protruding stopper 406 in the inner groove 405 of the second enclosure 400 of the upper layer of adjacent second enclosures 400 is arranged correspondingly to the third protruding stopper 407 of the second enclosure 400 of the lower layer, and when each second enclosure 400 is not subjected to external force, the upper end arm support of the inner groove 405 of the lowermost layer of at least two layers of second enclosures 400 The upper end arm of the inner groove 405 of the upper second enclosure 400 of the adjacent second enclosure 400 is supported on the upper end surface of the second enclosure 400 of the lower layer. When the upper second enclosure 400 of the adjacent second enclosure 400 rises relative to the second enclosure 400 of the lower layer until the second raised stopper 406 of the upper second enclosure 400 hits the lower end of the third raised stopper 407 of the second enclosure 400 of the lower layer and continues to rise, the upper second enclosure 400 can pass through the corresponding second raised stopper 406 and the third raised stopper 407. The limiting matching structure formed by the raised stop 407 lifts the second enclosure 400 below it. Similarly, preferably, when the pressure element applies pressure to the cement sample support structure sample, the second enclosure 400 of the lowest layer among at least two layers of the second enclosure 400 is not completely lifted, that is, the second raised stop 406 of the second enclosure 400 of the lowest layer among at least two layers of the second enclosure 400 has not yet hit the first raised stop 302 of the first enclosure 300. This ensures that when the pressure element breaks the cement sample and continues to move downward, the second enclosure 400 of the lowest layer among the second enclosure 400 still has room to rise.

[0050] Of course, in addition to the first and second embodiments mentioned above, the other specific structures in the present application are built up layer by layer, and are limited by designing other suitable limiting matching structures. Regardless of the first and second embodiments mentioned above, no upward gap (notch) is formed when the multi-layer enclosure parts are matched, and it is difficult to have a jamming phenomenon caused by debris and dust falling into the upward gap (notch).

[0051] According to one embodiment of the present application, the end of the telescopic member 202 is connected to a driving rod 4, a guide wheel 5 is provided on the bracket 100, and the traction mechanism is a traction rope 6 (such as a steel wire, a steel cable, etc.), which is hung on the guide wheel 5.

Specifically, the enclosure is preferably an annular plate-shaped member, and a first mounting ring 7 is connected above each of the radial ends of the uppermost enclosure of the multi-layer enclosure. The telescopic member A driving rod 4 is connected to each side of the end of 202, and a second mounting ring 8 is provided at the end of each driving rod 4 away from the telescopic member 202.

Another traction rope 6 is also installed in a similar manner. The traction rope 6 is on the side of the guide wheel 5 facing the driving rod 4, and the driving rod 4 and the second mounting ring 8 are all located within the vertical projection range of the space surrounded by the innermost enclosure in the multi-layer enclosure, ensuring that the driving rod 4 and the second mounting ring 8 will not interfere with the enclosure when moving downward.

The design of this embodiment can ensure that when the number of enclosures is sufficient, the uppermost enclosure can be lifted to be as close as possible to (but not close to, so as to ensure that when the pressure element breaks the cement sample and continues to move downward, the lowermost second enclosure 400 among the second enclosures 400 still has room to rise) the lower surface of the support plate 102, so as to better enclose and seal the pressure working space of the cement sample, and preferably has a rope through hole 103 located directly above the first mounting ring 7 for the first mounting ring 7 to enter.
