Description

Technical Field

[0001] This utility model belongs to the field of concrete pressure testing technology, and more specifically, it relates to a concrete block pressure testing machine. Background Technology

[0002] Concrete is widely used in various construction projects, from the foundation construction of high-rise buildings to the paving of bridges and roads. The compressive strength of concrete directly affects the safety and stability of the engineering structure. When evaluating the quality and performance of concrete, a concrete block compression testing machine is needed to test the concrete blocks. Existing concrete block compression testing machines mainly consist of a loading system, a worktable, a measuring device, and a control system. The worktable supports the concrete block specimen, and the loading system consists of a hydraulic pump station, cylinders, and pistons. The control system controls the loading system to apply pressure to the concrete block placed on the worktable, realizing the loading operation. The measuring device is usually a pressure sensor, which accurately measures the pressure value applied to the concrete block in real time and transmits the data to the control system.

[0003] Existing application number CN202322481474.X relates to a concrete block compression testing machine, which includes a frame. A support platform is fixedly connected to the top of the inner wall of the frame via a bracket. A test chamber is arranged in the middle of the top of the support platform. A test bench is arranged in the middle of the test chamber on the support platform. Slag discharge ports are opened on both sides of the test bench on the support platform. A cleaning component for cleaning the test bench is arranged inside the test chamber. A drying component for drying the test bench is arranged inside the test chamber. The drying component includes an air blowing pipe and several air blowing nozzles connected to the air blowing pipe. An air pump is connected to the end of the air blowing pipe away from the air blowing nozzles. The air blowing nozzles face the test bench. The test bench is dried by the drying component. The air pump is started to blow air onto the surface of the test bench to accelerate the drying of the test bench and facilitate the compression test of the next concrete block.

[0004] Based on the above, in existing concrete block pressure testing machines, after each concrete block has been pressure tested and broken, the concrete residue formed on the worktable due to the pressure must be cleaned before the next set of concrete blocks can be placed to continue the pressure test. This operation process is quite cumbersome, especially when testing a large number of concrete blocks. Frequent cleaning of the worktable will disrupt the continuity of the test process and affect the overall test efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a concrete block pressure testing machine. This addresses the issue that existing concrete block pressure testing machines require cleaning the concrete residue formed on the worktable after each pressure test and breakage of a concrete block before placing the next set of blocks for further pressure testing. This process is cumbersome, especially when testing large batches of concrete blocks, as frequent cleaning of the worktable disrupts the continuity of the testing process and affects overall testing efficiency.

[0006] The purpose and effect of this utility model, a concrete block pressure testing machine, are achieved by the following specific technical means:

[0007] A concrete block compression testing machine includes a main body, a hydraulic loading mechanism, a fixed base, a support base, a rotating worktable, a testing component, and a cleaning component. The hydraulic loading mechanism is installed on the upper part of the main body; the fixed base is fixedly installed on the lower part of the main body; the support base is fixedly installed on the upper part of the fixed base; the rotating worktable is rotatably connected to the top of the support base; the testing component is disposed on the upper part of the fixed base; and the cleaning component is disposed inside the rotating worktable.

[0008] Furthermore, the test assembly includes a drive motor and a drive shaft, wherein the drive motor is fixedly installed inside the support base; the drive shaft is fixedly connected inside the rotary table, and the drive shaft is fixedly installed on the upper part of the drive motor.

[0009] Furthermore, the test assembly also includes a loading plate and a bearing base, wherein the loading plate is fixedly installed at the bottom of the hydraulic loading mechanism; and the bearing base is fixedly installed on the upper part of the fixed base.

[0010] Furthermore, the test assembly also includes: a test groove, a trapezoidal slide, and a support plate. The test groove is formed on both sides inside the rotary table; the trapezoidal slide is formed on both sides inside the rotary table; and two sets of support plates are provided, with the two sets of support plates slidably connected inside the two sets of trapezoidal slides.

[0011] Furthermore, the cleaning assembly includes a support rod and an arc-shaped rack, wherein the support rod is fixedly installed on the upper part of the fixed base; and the arc-shaped rack is fixedly installed on the top of the support rod.

[0012] Furthermore, the cleaning assembly also includes: a rotating shaft, a drive gear, and a spiral spring. Two sets of rotating shafts are provided, rotatably connected to both sides inside the rotary table. Two sets of drive gears are provided, coaxially fixedly installed in the middle of the two sets of rotating shafts, and meshing with an arc-shaped rack. Two sets of spiral springs are provided, one end of each set fixedly connected to the inside of the rotary table, and the other end fixedly connected to the inside of the two sets of rotating shafts.

[0013] Furthermore, the cleaning assembly also includes: a driven rack and a collection bin. The driven rack is provided in two sets, which are fixedly installed on one side of two sets of support plates. The two sets of driven racks are slidably connected inside two sets of trapezoidal grooves. The two sets of driven racks mesh with two sets of drive gears respectively. The collection bin is placed on the upper part of the fixed base.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, this utility model has a test assembly. The drive motor drives the drive shaft to rotate, causing the rotating worktable to rotate. This allows the concrete blocks inside the two sets of test tanks to be rapidly alternated, facilitating the hydraulic loading mechanism to perform pressure tests on the concrete blocks. While the concrete in one set of test tanks is being tested, the broken concrete in the other set of test tanks can be cleaned and replaced, greatly improving the test efficiency.

[0016] Secondly, this invention features a cleaning component. When the tested concrete block is rotated by the rotating worktable to the position of the arc-shaped rack, the arc-shaped rack causes the drive gear to rotate, which in turn causes the driven rack to slide and move the bearing plate to open. This allows the broken concrete inside the test tank to fall into the collection chamber for centralized storage, eliminating the need for manual cleaning of the broken concrete inside the test tank. This greatly improves cleaning efficiency and reduces the labor intensity of workers. The only remaining step is to add concrete blocks inside the test tank.

[0017] This invention has the advantages of rapid alternation, improved efficiency, and easy cleaning. It allows the concrete blocks inside the two sets of test tanks to be rapidly alternating, which greatly improves the test efficiency. Moreover, it eliminates the need for manual cleaning of the broken concrete inside the test tanks, thus greatly improving the cleaning efficiency. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a concrete block pressure testing machine, including a pressure testing machine body 1, a hydraulic loading mechanism 2, a fixed base 3, a support base 4, a rotating worktable 5, and a testing component; the hydraulic loading mechanism 2 is installed on the upper part of the pressure testing machine body 1; the fixed base 3 is fixedly installed on the lower part of the pressure testing machine body 1; the support base 4 is fixedly installed on the upper part of the fixed base 3; the rotating worktable 5 is rotatably connected to the top of the support base 4; and the testing component is set on the upper part of the fixed base 3.

[0029] The test components include a drive motor 401 and a drive shaft 501. The drive motor 401 is fixedly installed inside the support base 4. The drive shaft 501 is fixedly connected inside the rotary table 5 and is fixedly installed on the upper part of the drive motor 401.

[0030] The test components also include: a loading plate 201 and a bearing base 301. The loading plate 201 is fixedly installed at the bottom of the hydraulic loading mechanism 2; the bearing base 301 is fixedly installed on the upper part of the fixed base 3.

[0031] The test components also include: a test groove 502, a trapezoidal slide 503, and a support plate 6. The test groove 502 is opened on both sides inside the rotary table 5; the trapezoidal slide 503 is opened on both sides inside the rotary table 5; and two sets of support plates 6 are provided, with the two sets of support plates 6 slidably connected inside the two sets of trapezoidal slides 503.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When a pressure test is required on a concrete block, the concrete block is placed inside the test chamber 502 on the left side. The bearing plate 6 supports the concrete block, the drive motor 401 is powered on, and the drive motor 401 drives the drive shaft 501 to rotate. The rotation of the drive shaft 501 drives the rotating worktable 5 to rotate, so that the concrete block rotates to the bottom of the loading pressure plate 201. The hydraulic loading mechanism 2 uses the hydraulic principle to drive the loading pressure plate 201 to perform a pressure test on the concrete block on the bearing plate 6. The sensor inside the hydraulic loading mechanism 2 measures the pressure value applied to the concrete block in real time and accurately. The bearing base 301 supports the compressed concrete block, making the concrete block more stable under pressure.

[0034] After a set of concrete blocks has been tested, the rotating worktable 5 rotates to allow the concrete blocks inside the two sets of test chambers 502 to be quickly alternated, facilitating the rapid pressure test of the next set of concrete blocks.

[0035] Example 2:

[0036] Based on Example 1, such as Figures 1 to 5 As shown, it also includes a cleaning component, which is disposed inside the rotary table 5.

[0037] The cleaning components include a support rod 303 and an arc-shaped rack 304. The support rod 303 is fixedly installed on the upper part of the fixed base 3, and the arc-shaped rack 304 is fixedly installed on the top of the support rod 303.

[0038] The cleaning assembly also includes: a rotating shaft 701, a drive gear 7, and a spiral spring 702. Two sets of rotating shafts 701 are provided, and the two sets of rotating shafts 701 are rotatably connected to both sides inside the rotary table 5. Two sets of drive gears 7 are provided, and the two sets of drive gears 7 are coaxially fixedly installed in the middle of the two sets of rotating shafts 701. The two sets of drive gears 7 and the arc-shaped rack 304 mesh with each other. Two sets of spiral springs 702 are provided, with one end of the two sets of spiral springs 702 fixedly connected to the inside of the rotary table 5, and the other end of the two sets of spiral springs 702 fixedly connected to the inside of the two sets of rotating shafts 701.

[0039] The cleaning assembly also includes: a driven rack 601 and a collection chamber 302. Two sets of driven racks 601 are provided. The two sets of driven racks 601 are fixedly installed on one side of the two sets of bearing plates 6. The two sets of driven racks 601 are slidably connected inside the two sets of trapezoidal slide grooves 503. The two sets of driven racks 601 mesh with the two sets of drive gears 7 respectively. The collection chamber 302 is placed on the upper part of the fixed base 3.

[0040] The specific usage and function of this embodiment are as follows:

[0041] After a set of concrete blocks has been tested, the rotating worktable 5 rotates, causing the concrete blocks inside the two sets of test chambers 502 to alternate rapidly. The concrete blocks that have been tested are moved by the rotating worktable 5 to the position of the arc-shaped rack 304. The arc-shaped rack 304 and the drive gear 7 mesh with each other, causing the drive gear 7 to rotate. The rotation of the drive gear 7 causes the rotating shaft 701 to rotate. The rotation of the rotating shaft 701 causes the driven rack 601 to slide inside the trapezoidal slide 503 and compress the spiral spring 702. The sliding of the driven rack 601 causes the bearing plate 6 to move. The trapezoidal slide 503 plays a guiding role when the driven rack 601 and the bearing plate 6 move. The movement of the bearing plate 6 opens the test chamber 502, allowing the broken concrete placed inside the test chamber 502 to fall into the collection chamber 302 for centralized storage, eliminating the need for manual cleaning of the broken concrete inside the test chamber 502.

[0042] When the rotating worktable 5 rotates to the horizontal position of the fixed base 3, the drive gear 7 and the arc rack 304 disengage. Under the elastic action of the spiral spring 702, the arc rack 304 is driven to reset and rotate, so that the bearing plate 6 closes the test slot 502, which facilitates the addition and replacement of concrete test blocks.
