[0040] As Figures 1 to 7 As shown in the figure, the present application provides a splitting mechanism, the splitting mechanism 10 includes longitudinal splitting assembly 1 and transverse splitting knife 2, longitudinal splitting assembly 1 includes first mounting seat 11 and second mounting seat 12, first mounting seat 11 and second mounting seat 12 are oppositely arranged along the height direction (Z direction in the figure, which is perpendicular to X direction and Y direction two by two), and can move relatively under the action of external force, the opposite surface of first mounting seat 11 and second mounting seat 12 is provided with opposite first splitting protrusion 13, and at least one of first mounting seat 11 and second mounting seat 12 and first splitting protrusion 13 has elastic element 14; first splitting protrusion 13 is arranged along the first direction (X direction in the figure, which is perpendicular to Y direction and Z direction two by two) of the longitudinal splitting assembly 1, and the second direction (Y direction in the figure, which is perpendicular to X direction and Z direction two by two) of the longitudinal splitting assembly 1 is perpendicular to the first direction (X direction in the figure, which is perpendicular to Y direction and Z direction two by two) of the longitudinal splitting assembly 1. Figure 1 The transverse splitting knife 2 is arranged on the first mounting seat 11 and the second mounting seat 12, and the transverse splitting knife 2 is arranged along the second direction (Y direction in the figure, which is perpendicular to X direction and Z direction two by two) of the longitudinal splitting assembly 1.Figure 1 The transverse splitting knife 2 is provided with a splitting groove 21, and the first mounting seat 11 and the second mounting seat 12 are provided with the transverse splitting knife 2 on both sides in the first direction, and the splitting grooves 21 on the same side of the first mounting seat 11 and the second mounting seat 12 are opposite to each other. The bottom of the splitting groove 21 is provided with a second splitting protrusion 22.
[0041] The transverse splitting knife 2 is provided on both sides of the first mounting seat 11 and the second mounting seat 12 in the first direction, that is, the transverse splitting knife 2 is located at both ends of the first splitting protrusion 13. When splitting, a square concrete core sample (hereinafter referred to as a core sample) of an appropriate size is clamped in the splitting groove 21 (at this time, the length direction of the core sample is the same as the first direction), and the first mounting seat 11 or the second mounting seat 12 is forced to split. Because there is an elastic member 14 between at least one of the first mounting seat 11 and the second mounting seat 12 and the first splitting protrusion 13, the second splitting protrusion 22 provided at the bottom of the splitting groove 21 splits the core sample (transverse splitting) and the first splitting protrusion 13 splits the core sample (longitudinal splitting) out of synchronization, so that different time and different direction splitting data can be collected, and the final data is more accurate. The first splitting protrusion 13 and the second splitting protrusion 22 can reduce the contact area when the force is applied to the core sample as much as possible, and the force is more concentrated, which can reduce the force as much as possible, so that a smaller force device can be used, and the equipment space and cost are further reduced.
[0042] As shown in Figure 3 In some embodiments, the first mounting seat 11 and the second mounting seat 12 each include a bottom plate 111 and two side plates 112, and the two side plates 112 are arranged on the bottom plate 111 and located at both ends of the bottom plate 111. The side plate 112 of the second mounting seat 12 is provided with a sliding groove 121 opened in the height direction, and the side plate 112 of the first mounting seat 11 is provided with a sliding protrusion 113 which slides in the sliding groove 121, so that the first mounting seat 11 and the second mounting seat 12 can keep stable during moving close to or away from each other.
[0043] As shown in Figure 1As shown, the transverse splitting knife 2 is detachably connected with the first mounting seat 11, so as to facilitate replacement; similarly, the transverse splitting knife 2 is also detachably connected with the second mounting seat 12. Exemplarily, a threaded hole is arranged on the side plate 112, and a through hole is arranged on the transverse splitting knife 2, and a bolt is screwed into the threaded hole through the through hole, so as to fix the transverse splitting knife 2. In order to avoid the bolt being broken due to excessive force during the splitting of the core sample by the transverse splitting knife 2, ensure normal splitting, and prolong the service life of the bolt, the bottom plate 111 of the first mounting seat 11 and the second mounting seat 12 is provided with a plug-in groove 15, the groove of the plug-in groove 15 on the first mounting seat 11 is opposite to the groove of the plug-in groove 15 on the second mounting seat 12, and the transverse splitting knife 2 is plugged into the plug-in groove 15, so as to form an auxiliary support by the groove bottom of the plug-in groove 15 abutting against the transverse splitting knife 2, and ensure the stability of the transverse splitting knife 2.
[0044] As shown in Figure 5 In some embodiments, the size of the splitting groove 21 gradually increases from the groove bottom to the groove opening, so that when the transverse splitting knife 2 on the first mounting seat 11 and the second mounting seat 12 clamps the core sample, the closer they are, the smaller the space of the splitting groove 21 for clamping the core sample in the second direction, and the second splitting protrusion 22 arranged on the groove bottom of the splitting groove 21 makes it more labor-saving to split the core sample.
[0045] As shown in Figure 1 , Figure 5 and Figure 6 In some embodiments, in order to make the test results more accurate, the first splitting protrusion 13 and the second splitting protrusion 22 are both arranged in multiple in the second direction, so as to be able to split multiple times in the same direction, thereby being able to collect more splitting data and provide more data support for the concrete strength test. In order to balance the relationship between the size of the device and the data, in the current embodiment, the first splitting protrusion 13 and the second splitting protrusion 22 are both arranged in two. Further, in the current embodiment, the second splitting protrusion 22 is located on the extension line of the first splitting protrusion 13 in the first direction, so that the spacing of adjacent first splitting protrusions 13 is the same as the spacing of adjacent second splitting protrusions 22, so that the test data is more representative.
[0046] As shown in Figure 1 and Figure 4As shown, in order to avoid the transverse splitting and longitudinal splitting interfering with each other when splitting, the transverse splitting data and longitudinal splitting data can be collected respectively, so as to improve the accuracy of the collected data as much as possible. In some embodiments, the longitudinal splitting assembly 1 further comprises two splitting plates 16, and the first splitting protrusion 13 is arranged on the splitting plate 16. One of the splitting plates 16 is fixed to the bottom plate 111 of the first mounting seat 11, and the bottom plate 111 of the second mounting seat 12 is provided with a sliding hole. The side of the splitting plate 16 facing the second mounting seat 12 is provided with a fixing hole, and one end of the fixing column is fixed in the fixing hole of the splitting plate 16 and the other end moves in the sliding hole. The sliding hole and the fixing hole are both stepped holes, and the elastic member 14 in the form of a ring is arranged in the sliding hole. The elastic member 14 protrudes from the sliding hole and abuts against the step of the fixing hole, so that there is a gap between the splitting plate 16 and the bottom plate 111 of the second mounting seat 12. When the second splitting protrusion 22 splits the core sample, the core sample abuts against the splitting plate 16 of the second mounting seat 12, so that the core sample can be kept stable. At this time, the splitting plate 16 contacts the core sample, but the splitting plate 16 can extrude the elastic member 14, so that the splitting plate 16 has a certain space for movement. The first splitting protrusion 13 will not affect the splitting of the core sample by the second splitting protrusion 22. Only by continuously moving the first mounting seat 11 and the second mounting seat 12 relative to each other and continuously extruding the elastic member 14 to be completely compressed, the first splitting protrusion 13 can split the core sample. That is, the elastic member 14 can reserve a time interval for the first splitting protrusion 13 and the second splitting protrusion 22 to split the core sample, so as to avoid the splitting interfering with each other. Exemplarily, the gap between the splitting plate 16 and the bottom plate 111 of the second mounting seat 12 can be but is not limited to 1 mm. The elastic member 14 can be but is not limited to a polyurethane elastic ring. In some alternative embodiments, the elastic member 14 can also be arranged between the splitting plate 16 and the bottom plate 111 of the first mounting seat 11.

The base 40 is provided with a vertical guide column 50, and the fixed plate 20 is arranged on the guide column 50 and spaced apart from the base 40. A pressure sensor 100 is arranged on the side of the fixed plate 20 facing the base 40. The base 40 is further provided with a driving member 30, and the first mounting seat 11 and the second mounting seat 12 slide on the guide column 50. In the present embodiment, the first mounting seat 11 is located above the second mounting seat 12, so that the driving member 30 can drive the second mounting seat 12 to rise. The core sample clamped by the first mounting seat 11 and the second mounting seat 12 can drive the first mounting seat 11 to abut against the pressure sensor 100, so that the pressure of the fracturing can be reflected by the pressure sensor 100, and the strength of the concrete can be calculated.
[0048] In some embodiments, two guide columns 50 are arranged on the base 40, and the upper beam 70 and the lower beam 80 are sleeved on the guide columns 50, the upper beam 70 is below the fixed plate 20, the first mounting seat 11 is fixed to one side of the upper beam 70 facing the lower beam 80, the second mounting seat 12 is fixed to one side of the lower beam 80 facing the upper beam 70, so as to facilitate the sliding of the first mounting seat 11 and the second mounting seat 12 on the guide column 50, and when the driving member 30 is driven, the driving member 30 only needs to drive the lower beam 80 to rise. Further, the guide column 50 is provided with a limiting ring 90, and the limiting ring 90 is arranged below the lower beam 80, so that when the splitting is not performed, the lower beam 80 abuts against the limiting ring 90, based on this, the driving end of the driving member 30 does not need to be fixedly connected with the lower beam 80, so that after the splitting is completed, the gravity of the lower beam 80 does not need to be borne by the driving member 30, and the probability of damage of the driving member 30 is reduced. Exemplarily, the driving member 30 can be, but is not limited to, a jack.
[0049] In some embodiments, the splitting test device further comprises two baffles 60 arranged on opposite sides of the upper beam 70, so that the two baffles 60 are arranged on both sides of the splitting mechanism 10 along the first direction, so as to avoid the splitting mechanism 10 from splashing when splitting the core sample, and improve the safety. Further, in order to facilitate the installation and placement of the core sample under the premise of arranging the baffle 60, and avoid frequent disassembly and assembly of the baffle 60, the baffle 60 is a folding baffle 60, the baffle 60 comprises a first plate 601 and a second plate 602, the first end of the first plate 601 is connected to the upper beam 70, the first end of the second plate 602 is hinged to the second end of the second plate 602, and the first plate 601 and the second plate 602 are in an inverted L shape in a natural state. When the core sample needs to be placed, the second plate 602 only needs to be rotated around the first plate 601.
