Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete quality detection press. Background Art

[0002] In a construction project, after completing a concrete pouring work, it is necessary to sample the concrete of the current pouring batch and make it into test blocks for inspection. The concrete after inspection needs to undergo a variety of tests, one of which is the compressive strength test. This test is carried out by placing the concrete test block under a press to determine whether the test block is qualified by monitoring its deformation and ultimate bearing capacity. Since the current test blocks are manually placed on the platform and aligned with the pressure mechanism, there is a certain amount of deviation. The deviation will cause the stress on the test block to be unbalanced, which will lead to errors in the test data.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0011] Furthermore, a limiting slide groove is provided at the upper end of the platform, and the push frame includes a screw sleeve that is sleeved on the bidirectional threaded screw and slides, a connecting slide rod that is arranged on the screw sleeve and slides in the limiting slide groove, and a push rod that is arranged at one end of the screw sleeve away from the connecting slide rod.

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 A concrete quality inspection press shown in the figure comprises a platform 1 and a pressure mechanism 11 arranged on the platform 1, a bearing platform 2 facing the pressure mechanism 11 is arranged on the platform 1; synchronously movable push frames 21 are arranged opposite to each other in pairs on the four sides of the bearing platform 2 on the platform 1; a driving component for driving the push frames 21 to move is arranged at the lower end of the platform 1, the bearing platform 2 is used to place the concrete test block, and the staff does not need to adjust and center the test block, but only needs to place it on the bearing platform 2, and then the driving component can be used to drive the push frames 21 on the four sides of the bearing platform 2 to synchronously move toward the concrete test block, and then push the test block to align it, so that it is completely aligned with the pressure mechanism 11, to ensure subsequent force balance.

[0026] In one embodiment, the driving assembly includes four groups of bearing frames 3 arranged at the lower end of the platform 1, two groups of bidirectional threaded screws 31 that are orthogonal in the horizontal direction and staggered in the longitudinal direction, and rockers 32 respectively arranged at one end of the two groups of bidirectional threaded screws 31. The two ends of the bidirectional threaded screw 31 are rotatably connected to the bearing frames 3. A limiting slide groove 12 is arranged at the upper end of the platform 1. The push frame 21 includes a screw sleeve 22 that is sleeved on the bidirectional threaded screw 31 and slides, a connecting slide rod 23 that is arranged on the screw sleeve 22 and slides in the limiting slide groove 12, and a push rod 24 that is arranged at one end of the screw sleeve 22 away from the connecting slide rod 23. By manually shaking the rocker arm 32, the bidirectional threaded screw 31 is rotated, and then the screw sleeve 22 on the bidirectional threaded screw 31 is relatively moved, thereby driving the push rod 24 to move, so that it abuts against the side of the concrete test block, thereby pushing it to the center position on the supporting platform 2.

[0027] In one embodiment, the platform 1 is further provided with an enclosure cover 4 that encloses three sides of the supporting platform 2, which is used to enclose concrete fragments after being crushed under pressure to prevent them from splashing and causing environmental pollution. Track rods 41 are provided at both ends of the opening side of the enclosure cover 4, and a sliding door 42 that can move up and down is provided on the track rod 41. A limiting slide rail 43 with a "T"-shaped cross-section is provided on the track rod 41. T-shaped blocks 44 that slide in the limiting slide rail 43 are provided at both ends of the sliding door 42. The sliding door 42 is movably connected with the track rod 41 through the T-shaped blocks 44 on both sides, and can then slide up and down, which is convenient for cooperating with the enclosure cover 4 for enclosure, and is also convenient for opening to place concrete test blocks. The lower end of the sliding door 42 is provided with an active notch 45 that is adapted to the corresponding side push rod 24, so that the active notch 45 will not be blocked because the lower push rod 24 cannot cooperate with the enclosure cover 4 to be completely closed.

[0028] In one embodiment, a limiting hole 5 is further provided on the sliding stop door 42, and a "door"-shaped handle 51 that can slide forward and backward is provided in the limiting hole 5, and a supporting block 52 for overlapping the handle 51 is provided on the track rod 41. When it is necessary to place the concrete test block, the sliding stop door 42 is lifted by holding the handle 51 by hand, and then the handle 51 is pulled backward so that both sides of it are supported on the supporting block 52 for stability, thereby making it convenient for the staff to free their hands to carry the test block.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
