Description

Technical Field

[0001] The utility model belongs to the technical field of cement block experiments, and particularly relates to a bearing platform for block compression tests. Background Art

[0002] A cement compression testing machine is a device specifically designed to test the compressive strength of cement. Its primary function is to simulate the pressures cement might experience in real-world conditions. By applying pressure, it tests the compressive properties of cement, thereby assessing its quality and suitability. It is a crucial testing tool in the cement industry. When using a cement compression testing machine, certain operating procedures must be followed, including specimen preparation, machine setup, test process monitoring, and data recording and analysis.

[0003] Among them, before conducting a compression test on the cement block, it is first necessary to place the standard cement block in the middle of the supporting platform. However, since the supporting platform of the existing cement compression testing machine lacks markings and rulers, the staff cannot accurately align the cement block with the upper pressure plate, which will increase the experimental error of the cement block and also increase the staff's misjudgment of the compressive performance of the cement block.

[0004] Therefore, in order to solve the above technical problems, it is necessary to provide a bearing platform for block compression testing.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a bearing platform for block compression test, which can solve the problem that cement blocks cannot be accurately placed.

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by a specific embodiment of the present invention is as follows:

[0008] A bearing platform for block compression test, comprising: a compression test machine body and an L-shaped scale;

[0009] The compression testing machine body is provided with a base, a bearing platform is provided on the base, and a plurality of standard scale grooves evenly distributed around the circumference are cut on the end surface of the bearing platform;

[0010] The L-shaped ruler is placed on the supporting platform. Both ends of the L-shaped ruler are provided with indicating scale grooves, and the indicating scale grooves correspond to the standard scale grooves. A pair of adsorption fixing mechanisms are installed on the L-shaped ruler.

[0011] In one or more embodiments of the present invention, the adsorption and fixing mechanism includes a threaded sleeve, which is embedded in the L-shaped ruler and is used to install an adjusting screw;

[0012] The threaded sleeve is internally threaded with an adjusting screw, which can rotate in the threaded sleeve to adjust the distance between the contact plate and the supporting platform.

[0013] In one or more embodiments of the present invention, the length of the adjusting screw is greater than the thickness of the L-shaped ruler. When the magnet embedded in the contact plate is attracted to the supporting platform, the L-shaped ruler can be fixed on the supporting platform. When the magnet is out of contact with the supporting platform, the L-shaped ruler can be removed from the supporting platform, which is not likely to affect the normal compressive strength test of the cement block.

[0014] In one or more embodiments of the present invention, one end of the adjusting screw is connected to a contact plate, and the contact plate is used to mount the magnet and the annular pad;

[0015] The bottom of the L-shaped ruler is provided with a accommodating cavity that matches the contact plate. The accommodating cavity is used to accommodate the contact plate. When the contact plate is completely accommodated in the accommodating cavity, the magnet can be separated from the attractive contact with the supporting platform, and the L-shaped ruler can be easily removed from the supporting platform.

[0016] In one or more embodiments of the present invention, a magnet is embedded in the bottom of the contact plate, and the magnet is attracted to the supporting platform. Through the mutual attraction between the magnet and the supporting platform, an L-shaped ruler can be fixed, so that the cement block can be placed in the standard position using the L-shaped ruler, thereby facilitating the compressive strength test of the cement block to reduce experimental errors, and at the same time ensure that the staff can accurately determine the compressive performance of the cement block.

[0017] In one or more embodiments of the present invention, an annular cavity is bored at the bottom of the contact plate, an annular plate is slidably provided in the annular cavity, and the annular plate is used to install an annular gasket.

[0018] In one or more embodiments of the present invention, an annular pad is connected to the annular plate, and the annular pad is in contact with the L-shaped ruler. The annular pad is used to increase resistance so that the L-shaped ruler is not easy to slide when the magnet is adsorbed and fixed on the supporting platform.

[0019] In one or more embodiments of the present invention, the inner diameter of the annular pad is larger than the outer diameter of the magnet and smaller than the outer diameter of the contact plate.

[0020] In one or more embodiments of the present invention, an extrusion ring is provided in the annular cavity, and the extrusion ring contacts the annular plate. The extrusion ring is used to squeeze the annular plate so that the annular pad connected to the annular plate protrudes from the contact plate in a natural state.

[0021] In one or more embodiments of the present invention, the annular pad and the extrusion ring are both made of elastic rubber material. When the magnet is adsorbed and fixed to the supporting platform, the extrusion ring can be squeezed, so that the annular pad can better contact with the supporting platform.

[0022] Compared with the existing technology, the utility model provides a bearing platform for block compression test, which can accurately place the cement block at the center of the bearing platform, thereby facilitating the compressive strength test of the cement block, thereby reducing experimental errors and ensuring that staff can accurately determine the compressive performance of the cement block.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 6 As shown, a bearing platform for block compression test in one embodiment of the present invention includes a compression testing machine body 1 and an L-shaped scale 2.

[0034] The compression testing machine body 1 is provided with a base 101 for installing a bearing platform 102 . The base 101 is provided with a bearing platform 102 for placing cement blocks so as to conduct compression performance tests on the cement blocks.

[0035] In addition, a number of standard scale grooves 103 evenly distributed around the circumference are carved on the upper end surface of the supporting platform 102. There are four standard scale grooves 103, which are arranged at 90° to each other. The standard scale grooves 103 are used to determine the standard position of the L-shaped scale 2 so that subsequent cement blocks can be accurately placed on the supporting platform 102.

[0036] When determining the standard position of the L-shaped ruler 2, first measure the length and width of the cement block, and divide the measured values ​​by two to obtain the distance from each side of the L-shaped ruler 2 to the center of the support platform 102. Since the pair of standard scale grooves 103 are at 90 degrees to each other, the standard position of the L-shaped ruler 2 can be determined by simply placing the two sides of the L-shaped ruler 2 perpendicularly to the pair of standard scale grooves 103. Figures 1 to 2 The status shown.

[0037] like Figures 1 to 6 As shown, the L-shaped ruler 2 is placed on the supporting platform 102. When the L-shaped ruler 2 is placed in the standard position, one of the right-angled sides of the cement block coincides with the L-shaped ruler 2, that is, the standard position of the cement block can be accurately determined, and deviation is not easy to occur, so as to ensure the accuracy of the subsequent compressive performance test data of the cement block.

[0038] Wherein, both ends of the L-shaped scale 2 are provided with indicating scale grooves 201, and the indicating scale grooves 201 correspond to the standard scale grooves 103. The indicating scale grooves 201 can assist in measuring the length and width of the cement block.

[0039] like Figures 1 to 6As shown, a pair of adsorption fixing mechanisms are installed on the L-shaped ruler 2, which are used to fix the L-shaped ruler 2 so that the L-shaped ruler 2 is not easy to move on the supporting platform 102, so as to ensure that the L-shaped ruler 2 can accurately determine the standard position of the cement block and is not prone to deviation.

[0040] The adsorption and fixing mechanism includes a threaded sleeve 202, which is embedded in the L-shaped scale 2 and is used to install an adjustment screw 203. The adjustment screw 203 is connected to the inner thread of the threaded sleeve 202. The adjustment screw 203 can rotate within the threaded sleeve 202 to adjust the distance between the contact plate 204 and the support platform 102.

[0041] Preferably, the length of the adjusting screw 203 is greater than the thickness of the L-shaped ruler 2. When the magnet 206 embedded in the contact plate 204 is attracted to the support platform 102, the L-shaped ruler 2 can be fixed to the support platform 102. When the magnet 206 is no longer in contact with the support platform 102, the L-shaped ruler 2 can be removed from the support platform 102, thereby minimizing the impact on the normal compression test of the cement block.

[0042] In addition, one end of the adjusting screw 203 is connected to a contact plate 204 for mounting a magnet 206 and an annular pad 209. A receiving cavity 205 is provided at the bottom of the L-shaped scale 2, which matches the contact plate 204. The receiving cavity 205 is used to accommodate the contact plate 204. When the contact plate 204 is fully accommodated in the receiving cavity 205, the magnet 206 can be disengaged from the support platform 102, allowing the L-shaped scale 2 to be easily removed from the support platform 102.

[0043] like Figures 1 to 6 As shown, a magnet 206 is embedded in the bottom of the contact plate 204, and the magnet 206 is attracted to the support platform 102. The mutual attraction between the magnet 206 and the support platform 102 can fix the L-shaped ruler 2, so that the L-shaped ruler 2 can be used to place the cement block in the standard position, thereby facilitating the compressive strength test of the cement block, reducing experimental errors, and ensuring that the staff can accurately determine the compressive performance of the cement block.

[0044] The contact plate 204 has an annular cavity 207 at its bottom. An annular plate 208 slides within the cavity, mounting an annular pad 209. Connected to the annular plate 208 is an annular pad 209, which contacts the L-shaped scale 2. This pad increases resistance, preventing the L-shaped scale 2 from sliding when the magnet 206 is attached to the support platform 102.

[0045] Preferably, the inner diameter of the annular pad 209 is larger than the outer diameter of the magnet 206 and smaller than the outer diameter of the contact plate 204 .

[0046] In addition, an extrusion ring 210 is provided in the annular cavity 207 and contacts the annular plate 208. The extrusion ring 210 is used to squeeze the annular plate 208 so that the annular pad 209 connected to the annular plate 208 protrudes from the contact plate 204 in a natural state.

[0047] Specifically, the annular pad 209 and the extrusion ring 210 are both made of elastic rubber. When the magnet 206 is adsorbed and fixed to the supporting platform 102 , the extrusion ring 210 can be squeezed, so that the annular pad 209 can better contact with the supporting platform 102 .

[0048] In specific use, when it is necessary to place a cement block, first measure the length and width of the cement block, and divide the measured values ​​by two to obtain the distance from the two sides of the L-shaped ruler 2 to the center of the supporting platform 102. Place the two sides of the L-shaped ruler 2 perpendicularly to a pair of standard scale grooves 103 to determine the standard position of the L-shaped ruler 2, that is, Figures 1 to 2 The status shown.

[0049] When placing the L-shaped ruler 2, it is necessary to rotate the pair of adjustment screws 203 separately, bringing the contact plate 204 into close proximity with the support platform 102 until the magnet 206 and the support platform 102 are attracted to each other, thereby allowing the L-shaped ruler 2 to be adsorbed and fixed to the support platform 102. When the magnet 206 is adsorbed and fixed to the support platform 102, the annular pad 209, in conjunction with the annular plate 208 and the extrusion ring 210, also contacts the support platform 102. The annular pad 209 is used to increase resistance, preventing the L-shaped ruler 2 from moving while adsorbed and fixed to the support platform 102, thereby ensuring the accuracy of the subsequent placement of the cement block.

[0050] By aligning one of the right-angled sides of the cement block with the two sides of the L-shaped ruler 2, the standard position of the cement block can be accurately determined.

[0051] The adjusting screw 203 is rotated in the reverse direction to disengage the magnet 206 on the contact plate 204 from the support platform 102 , and the L-shaped scale 2 can be removed from the support platform 102 so that the cement block can be subjected to a compression performance test.

[0052] The present application is provided with an L-shaped ruler 2 that matches the cement block. The L-shaped ruler 2 can be moved. When the cement block needs to be placed, it can be moved to the standard position. Placing the cement block can ensure that it is in the standard position, and then the L-shaped ruler 2 can be moved to one side without affecting the normal test.

[0053] It will be apparent 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 essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
