Description

Technical Field

[0001] The present application relates to the technical field of concrete testing equipment, and in particular to a concrete strength testing instrument. Background Art

[0002] The concrete pressure testing machine includes a matching pressure main body and an operating main body. It is mainly used to detect the maximum ultimate pressure resistance and compressive strength of concrete test blocks and the stability of physical properties under constant load. It is widely used in compressive strength tests of cement concrete, ceramics, bricks, stones and other building materials.

[0003] During the test, the concrete sample needs to be prepared into a test block of standard size and shape, and the concrete test block is placed on the test table of the main body of the pressure, and pressure is gradually applied until the test block breaks. During the load application process, the load and deformation data are continuously recorded, and the compressive strength of the concrete is finally calculated based on the obtained data. In order to reduce the error caused by sampling, during the test, multiple test blocks of the same concrete sample will be used for multiple tests and the average value will be taken.

[0004] In actual testing, multiple different testing instruments are placed in one room, and there is often no storage table next to the concrete pressure testing machine. Therefore, testers need to go back and forth to pick up test blocks, or place multiple test blocks on the top of the instrument, and the operation process is not standardized. The Chinese patent with publication number CN210071508U discloses a recycled concrete pressure testing machine, in which a fixed clamp is installed on the supporting column of the main pressure body, an L-shaped connecting rod is installed on the outside of the fixed clamp, and a single-layer test block tray is set on the top of the connecting rod. The staff can place the obtained test block on the tray and directly take the test block from the tray during the test.

[0005] However, in order not to affect the use of other testing instruments or the passage of staff, the available floor space of the concrete pressure testing machine is limited, and the size of the pallet is limited, so the storage space of the pallet is limited, which is inconvenient when a large number of test blocks need to be stored, and there is still room for improvement. Utility Model Content

[0006] In order to increase the number of test blocks that can be stored on a support plate in a concrete pressure testing machine, the present application provides a concrete strength tester.

[0007] The concrete strength tester provided in this application adopts the following technical solution:

[0008] A concrete strength tester comprises a pressure-applying main body and a control main body for controlling the pressure-applying main body, the pressure-applying main body comprising a bottom plate, a top plate, a plurality of support columns respectively penetrating the bottom plate and the top plate at both ends, a test portion arranged at the upper end of the bottom plate, and a pressure-applying portion movably penetrating the top plate from top to bottom, a fixing ring is sleeved on both upper and lower ends of the support column, a connecting block is protrudingly provided on one side of the fixing ring, an installation column is connected between the upper and lower adjacent connecting blocks, the installation column is sleeved with a plurality of storage trays, and a storage space for placing test blocks is formed at the upper end of the storage tray.

[0009] By adopting the above technical solution, multiple storage trays installed from top to bottom are arranged on one side of the main pressure body. On the basis of not increasing the occupied space, the height space is fully utilized. On the one hand, the number of test blocks that can be stored on the pallet in the concrete pressure testing machine is increased. On the other hand, the tester can place the blocks to be tested or the tested blocks in the storage trays on different layers according to actual needs, thereby avoiding wrong or missed blocks, and being more adapted to actual needs.

[0010] Optionally, a semi-enclosed baffle is protruding from the side of the storage tray.

[0011] By adopting the above technical solution, during the process of placing the test blocks, the setting of the semi-enclosed baffle reduces the probability of the test blocks accidentally falling. The baffle can also be used to arrange the test blocks in an orderly manner to avoid collisions between the test blocks, thereby improving the reliability of the test results.

[0012] Optionally, a partition plate is provided in the middle of the upper end of the storage tray to divide the storage space into left and right parts.

[0013] By adopting the above technical solution, the setting of the partition plate further organizes the storage space. The tester can also choose to place the blocks to be tested and the tested blocks in the left and right parts of the storage space respectively according to the actual remaining storage space size, instead of having to place the tested blocks separately in another layer of storage space or handle them separately, making the testing process more flexible.

[0014] Optionally, an inserting plate is provided at the lower end of the partition plate, and an embedding groove for inserting the inserting plate is opened at the upper end of the storage tray.

[0015] By adopting the above technical solution, the partition plate can be detachably arranged, the structure is simple, and the split partition plate can be selected according to the size of the test block required for the test, which is more suitable for actual needs.

[0016] Optionally, a mounting ring is connected to one side of the storage tray, and the mounting ring is sleeved on the mounting post and is rotatably connected to the mounting post.

[0017] By adopting the above technical solution, the storage trays are arranged in multiple layers, and the mounting rings are used to realize the rotational connection between the storage trays and the mounting columns. The corresponding storage trays can be directly rotated to a position that is convenient for taking, which is more convenient. After the test blocks on the storage tray of this layer are tested, the storage trays are rotated in the opposite direction, so that the storage trays of this layer do not affect the taking of the test blocks on the storage trays of the lower layer.

[0018] Optionally, the mounting ring is a clamp.

[0019] By adopting the above technical solution, the clamp is easy to assemble and disassemble, and the mounting ring can be connected without removing the mounting column. The number of layers of the installed storage tray can be selected according to actual needs.

[0020] Optionally, a plurality of water holes are provided at intervals through the upper end surface of the storage tray.

[0021] By adopting the above technical solution, the concrete test block will generate dust after it is broken. After too much dust accumulates on the placement tray, it may be adsorbed on the new test block, causing slight changes in the size and shape of the test block, affecting the reliability of the test results. Therefore, the placement tray can be disassembled and flushed regularly, and the setting of the water hole improves the convenience of flushing.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present application sets a plurality of storage trays installed from top to bottom on one side of the main pressure body, which makes full use of the height space without increasing the occupied space. On the one hand, it increases the number of test blocks that can be stored on the pallet in the concrete pressure testing machine. On the other hand, the tester can place the test blocks or the tested blocks in the storage trays of different layers according to actual needs, thereby avoiding wrong or missed taking, which is more suitable for actual needs.

[0024] 2. In this application, the storage tray is rotatably connected to the mounting column. When the test block on a certain layer needs to be taken, the layer is rotated closer to the tester, and other storage trays that are not temporarily used are rotated away from the tester, which is more convenient;

[0025] 3. The present application increases the convenience of flushing by adding water holes on the storage tray, making it easier to flush the storage tray regularly, thereby reducing the dust accumulation on the upper end of the storage tray. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a concrete strength tester. Figure 1 The concrete strength tester includes a pressure main body 1 and a control main body 2 placed on one side of the pressure main body 1. The control main body 2 is used to control the pressure main body 1 and display the test result.

[0031] The main body of the pressure machine includes a bottom plate 11, a top plate 12, and a plurality of support columns 13 that penetrate the bottom plate 11 and the top plate 12 at both ends. The support columns 13 cooperate with the bottom plate 11 and the top plate 12 to form an overall frame. A test part 14 is installed on the upper end of the bottom plate 11. The top plate 12 is movably connected with a pressure part 15. The pressure part 15 penetrates the top plate 12 from top to bottom and is threadedly connected to the top plate 12, so that it can reciprocate in the vertical direction. When the concrete strength tester is working, the pressure part 15 approaches the test part 14 and continues to abut against the block to be tested placed on the upper end of the test part 14 until the block to be tested breaks.

[0032] Reference Figure 2 The upper and lower ends of the support column 13 are sleeved with a fixing ring 16, and the inner wall of the fixing ring 16 is tightly fitted with the outer peripheral surface of the support column 13, so that the fixing ring 16 can be sleeved on the support column 13 by friction fixation. A connecting block 17 is integrally formed on one side of the fixing ring 16, and a mounting column 18 is connected between the upper and lower adjacent connecting blocks 17, and the mounting column 18 is fixed by bolts inserted into the connecting block 17 and the mounting column 18 at the same time. The mounting column 18 is sleeved with multiple placement trays 3 from top to bottom, and the upper end of the placement tray 3 is formed with a placement space 31 for placing the test block.

[0033] A mounting ring 32 is welded to one side of the storage tray 3. The mounting ring 32 is sleeved with the mounting column 18 and is rotatably connected to the mounting column 18. In one specific embodiment, the mounting ring 32 is annular, sleeved with the mounting column 18 from top to bottom, and fixed to the mounting column 18 by friction; in another specific embodiment, the mounting ring 32 is a clamp, and one end of the clamp is tightened and loosened by a bolt, so that the clamp can also be fixed to the mounting column 18 by friction. Since the clamp is easy to assemble and disassemble, the mounting ring 32 can be connected without disassembling the mounting column 18. The embodiment of the present application takes the second specific embodiment as an example.

[0034] A semi-enclosed baffle 33 is welded to the side of the storage tray 3, and a partition plate 34 is detachably connected to the middle of the upper end of the storage tray 3 to divide the storage space 31 into two parts, left and right. An insert plate 341 is integrally formed at the lower end of the partition plate 34, and an embedding groove 35 for inserting the insert plate 341 is provided at the upper end of the storage tray 3. In order to facilitate flushing, a plurality of water holes 36 are provided at intervals through the upper end surface of the storage tray 3.

[0035] The implementation principle of a concrete strength tester in the embodiment of the present application is as follows: the tester places a block to be tested on the test part 14 for testing, and places other blocks to be tested on different layers of the trays 3. When the test is completed, the tested blocks are also placed on the trays 3, and the tested blocks are kept separate from the blocks to be tested to avoid taking the wrong blocks. Then, the blocks to be tested are taken out layer by layer from top to bottom and tested. If the test blocks of a layer need to be taken, the tray 3 of that layer is rotated close to the tester, and other trays 3 that are not used temporarily are rotated away from the tester to avoid missing blocks.

[0036] Before testing, the height of the mounting column 18 from the ground can be adjusted according to the actual needs of the tester to accommodate testers of different heights. When testing different types of test blocks, the number of trays 3 and the spacing between upper and lower adjacent trays 3 can be adjusted according to actual needs. The trays 3 should be disassembled and rinsed regularly.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
