Description

Technical Field

[0001] This utility model relates to the field of concrete pressure machine technology, specifically a concrete test block positioning and installation pressure machine. Background Technology

[0002] A concrete pressure tester is a type of press mainly used to test the compressive strength of building material specimens such as concrete, cement, high-strength bricks, and refractory materials. It can also be used to test the compressive strength of other non-metallic materials.

[0003] Currently, when using a concrete press, the operator places the concrete test block in the test area, directly beneath the indenter. After starting the press, the indenter moves downwards to compress the test block. However, there are no specific limiting components for placing the test block; adjustment relies solely on the operator's visual judgment. If the test block is out of the test area or misaligned, the pressure from the indenter will cause localized breakage, leading to inaccurate test results and potentially damaging the testing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a concrete test block positioning and installation pressure machine, which aims to solve the problem in the prior art where the concrete test block is misplaced and the pressure head causes the test block to break under localized stress, resulting in inaccurate test results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete test block positioning and installation pressure machine includes a testing device, the testing device including a fixed base, a support frame fixed on the fixed base, and a top pressure structure set on the support frame;

[0006] The fixed base is equipped with a limit component;

[0007] The limiting component is used to engage and adjust the concrete test block so that the concrete test block is located directly below the top pressure structure;

[0008] The limiting component includes a mounting plate disposed in a fixed base, a transmission component rotatably connected to the mounting plate, and a movable plate pulsatingly connected to the transmission component, wherein the movable plate is guided to move relative to the mounting plate;

[0009] An L-shaped clamping plate is fixedly provided on the top of the movable plate. The L-shaped clamping plate is located on the upper surface of the fixed base, so that the L-shaped clamping plate can limit the concrete test block.

[0010] The fixed base is provided with sliding holes for the L-shaped card plate to slide.

[0011] Preferably, the mounting base has a mounting groove, and the mounting plate is fixedly disposed in the mounting groove;

[0012] The mounting plate consists of two long plates spaced apart front to back and extending in the left-right direction.

[0013] Preferably, the transmission assembly is provided with two sets spaced apart on the left and right sides. The transmission assembly includes a second bidirectional lead screw extending in the front-back direction, a reciprocating block threadedly connected to the second bidirectional lead screw, and a connecting rod hingedly connected to the reciprocating block.

[0014] Two reciprocating blocks are corresponding to the same second bidirectional lead screw; the moving plate is hinged to the connecting rod, and two connecting rods are corresponding to the same reciprocating block, with the connecting rods distributed on the upper and lower sides of the same reciprocating block.

[0015] Preferably, a driving device is fixedly installed in the mounting slot;

[0016] The output shaft of the drive device is connected to one of the second bidirectional lead screws, and the output shaft of the drive device is also connected to the other second bidirectional lead screw via gear transmission.

[0017] Preferably, one end of each of the two second bidirectional lead screws passes through one of the long plates and is fixedly fitted with a gear. The two gears mesh with each other, and the drive device is connected to one of the gears in a transmission connection, so that the drive device drives the two second bidirectional lead screws to rotate, thereby moving the two reciprocating blocks on the same second bidirectional lead screw in opposite or opposite directions along the extension direction of the second bidirectional lead screw, and thus causing the two moving plates to move in opposite or opposite directions along the sliding holes.

[0018] The beneficial effects are: 1. The operator places the concrete test block on the fixed seat and only adjusts the position of the two L-shaped clamps to clamp the L-shaped clamps at the corners of the concrete test block so that the concrete test block is located directly under the top pressure structure. This ensures that the concrete test block is stable during the test, thereby improving the accuracy of the compressive strength test.

[0019] 2. The rotation of the two second bidirectional lead screws can drive the reciprocating blocks on the same second bidirectional lead screw to move, so that the two moving plates can drive the two L-shaped clamping plates to move in opposite or opposite directions, thereby making the two L-shaped clamping plates clamped at the corners of the concrete test block at the same time, avoiding the concrete test block not being directly below the top pressure structure on the fixed seat due to the different movement of the L-shaped clamping plates.

[0025] The following description, in conjunction with the accompanying drawings, further illustrates the specific implementation of a concrete test block positioning and installation pressure machine according to this utility model.

[0026] In this invention, the concrete test block 3 used in the concrete test block positioning and installation pressure machine is a cube or cuboid.

[0027] like Figure 1-4 As shown, a concrete test block positioning and installation pressure machine is mainly used to place the concrete test block 3 on a fixed seat. Then, under the action of the limiting component, the concrete test block 3 can be positioned directly below the top pressure structure so that the top pressure structure presses the concrete test block 3, thereby improving the accuracy of the test results. In the current concrete pressure machine, the operator places the concrete test block 3 on the fixed seat and visually adjusts the position of the concrete test block 3. However, visual adjustment can easily cause the concrete test block 3 to be misaligned, resulting in inaccurate test results.

[0028] In this embodiment, the concrete test block positioning and installation pressure machine includes a testing device 1. The testing device 1 includes a fixed base, a support frame fixed on the fixed base, and a top-pressing structure disposed on the support frame. In this embodiment, the top-pressing structure includes a pressure structure disposed above the support frame and a pressure head fixed at the lower end of the pressure structure, with the pressure head located below the support frame. When the pressure structure is activated, it can drive the pressure head to move downward. In this embodiment, the pressure structure can adopt an electric telescopic rod structure. The structure and principle of the electric telescopic rod are existing technologies and will not be described in detail here.

[0029] like Figure 1 and Figure 2 As shown, the fixed base is equipped with a limiting component, which is used to engage and adjust the concrete test block 3 so that the concrete test block 3 is located directly below the top pressure structure.

[0030] Specifically, the limiting component includes a mounting plate 101 disposed within a fixed base, a transmission assembly 102 rotatably connected to the mounting plate 101, and a movable plate 103 drively connected to the transmission assembly 102. The movable plate 103 guides and moves relative to the mounting plate 101. The transmission assembly 102 can drive the two movable plates 103 to move along the space between the two mounting plates 101, causing the two movable plates 103 to move in opposite or opposing directions. An L-shaped locking plate 4 is fixedly provided on the top of the movable plate 103. The L-shaped locking plate 4 is located in the fixed base. The upper surface of the base allows the L-shaped clamping plate 4 to limit the concrete test block 3. In this embodiment, the L-shaped clamping plate 4 is used to clamp the opposite corner of the concrete test block 3. The fixed base is provided with sliding holes for the L-shaped clamping plate 4 to slide. When the moving plate 103 moves, the sliding holes can drive the L-shaped clamping plate 4 to move along the sliding holes, which can limit the movement of the L-shaped clamping plate 4 and prevent the L-shaped clamping plate 4 from tilting. The L-shaped clamping plate 4 achieves clamping and positioning of the concrete test block 3 as the moving plate 103 moves.

[0031] In this embodiment, the L-shaped clamping plate 4 has rounded corners at its edges. The operator places the concrete test block 3 in the area of ​​the two L-shaped clamping plates 4, and the orientation of the concrete test block 3 is approximately the same as the orientation of the testing device 1. The rounded corners allow the L-shaped clamping plate 4 to engage with the edges of the concrete test block 3 when it is being adjusted.

[0032] like Figure 3 As shown, the mounting base has an installation groove 6, and the mounting plate 101 is fixedly installed in the installation groove 6; the mounting plate 101 is two long plates that are spaced apart front and back and extend in the left and right direction.

[0033] Two sets of transmission components 102 are arranged at intervals on the left and right sides. The transmission component 102 includes a second bidirectional lead screw 1021 extending in the front-back direction, a reciprocating block 1022 threadedly connected to the second bidirectional lead screw 1021, and a connecting rod 1023 hingedly connected to the reciprocating block 1022. Two reciprocating blocks 1022 are corresponding to the same second bidirectional lead screw 1021. When the second bidirectional lead screw 1021 rotates, it can drive the two reciprocating blocks 1022 on the same second bidirectional lead screw 1021 to move in opposite or opposite directions, so as to move the moving plate 103. The moving plate 103 is hingedly connected to the connecting rod 1023. Two connecting rods 1023 are corresponding to the same reciprocating block 1022, and the connecting rods 1023 are distributed on the upper and lower sides of the same reciprocating block 1022. The connection between the two connecting rods 1023 and the same reciprocating block 1022 enables the reciprocating block 1022 to drive the moving plate 103 to move more stably when moving, thereby improving stability.

[0034] A drive device 7 is fixedly installed in the mounting slot 6; the output shaft of the drive device 7 is connected to one of the second bidirectional lead screws 1021, and the output shaft of the drive device 7 is connected to another second bidirectional lead screw 1021 via gear transmission. When the drive device 7 is started, it can drive one of the second bidirectional lead screws 1021 to rotate.

[0035] One end of each of the two second bidirectional lead screws 1021 passes through one of the long plates and is fixedly fitted with a gear 8. The two gears 8 mesh with each other. The drive device 7 is connected to one of the gears 8, so that the drive device 7 drives the two second bidirectional lead screws 1021 to rotate. When the drive device 7 is started, it can also drive one of the gears 8 to rotate. Since the two gears 8 mesh with each other, it can drive the other gear 8 to rotate, and then drive the other second bidirectional lead screw 1021 to rotate. This moves the two reciprocating blocks 1022 on the same second bidirectional lead screw 1021 in opposite or opposite directions along the extension direction of the second bidirectional lead screw 1021, and then moves the two moving plates 103 in opposite or opposite directions along the sliding hole.

[0036] Working principle: The concrete test block 3 is placed on the fixed seat of the testing device 1 and placed within the area of ​​the two L-shaped clamping plates 4. After placement, the drive device 7 is activated, which drives one of the second bidirectional lead screws 1021 to rotate. The drive device 7 also drives one of the gears 8 to rotate. Since the two gears 8 mesh with each other, they can drive the other gear 8 to rotate, which in turn drives the other second bidirectional lead screw 1021 to rotate. When the second bidirectional lead screw 1021 rotates, it can drive the two reciprocating blocks 1022 on the same second bidirectional lead screw 1021 to move in opposite or opposite directions, so as to move the moving plate 103. When the moving plate 103 moves, it can drive the L-shaped clamping plate 4 to move along the sliding hole, so that the L-shaped clamping plate 4 engages the opposite corner of the concrete test block 3, positioning the concrete test block 3 directly below the top pressure structure, thus improving the accuracy of the test results.
