Description

Technical Field

[0001] This utility model relates to the field of hardness testing technology, specifically a concrete hardness testing device. Background Technology

[0002] The compressive strength of concrete is an important indicator for measuring concrete quality. The compressive strength of concrete is obtained by testing concrete test blocks through a concrete compressive strength testing device. The test blocks need to be cured in a curing room for a specified time before the test is conducted. After the concrete test blocks have been cured for the specified time, they are manually transported to the compressive strength testing device, and then the testing personnel manually place the concrete test blocks on the compressive strength testing device.

[0003] Publication number CN216449368U discloses a concrete hardness testing device. This device facilitates the handling of concrete test blocks during testing, and the lowering of the device automatically compresses the test blocks, preventing them from shifting and affecting the testing quality. However, this patent still has the following problems in practical use:

[0004] Testing the hardness of concrete test blocks not only facilitates the handling of the blocks by staff, but also allows the lowering of the hardness testing device to automatically compress the blocks, preventing them from shifting and affecting the quality of the test. However, after testing, residue remains on the concrete blocks, potentially impacting subsequent tests. Furthermore, some existing testing devices lack cleaning components, requiring manual cleaning by staff, which increases their workload.

[0005] A concrete hardness testing device is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a concrete hardness testing device to solve the problems mentioned in the background art. Currently, when testing the hardness of concrete test blocks, it is not only convenient for workers to handle the blocks, but also allows the lowering of the hardness testing device to automatically press the blocks together, preventing them from moving and affecting the testing quality. However, after testing, residue remains on the concrete blocks on the worktable, which may affect subsequent testing. Furthermore, some existing testing devices lack cleaning components, requiring workers to clean them manually, increasing their workload.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a concrete hardness testing device, including a base, wherein a connecting frame is fixedly installed on the top surface of the base;

[0008] A cylinder is fixedly installed in the middle of the top surface of the connecting frame. A detection device is fixedly installed on one side surface of the connecting frame through the output end of the cylinder. Electric push rods are connected through the two sides of the connecting frame near the bottom. A clamping plate is fixedly connected to one side surface of the output end of the electric push rod. A friction pad is fixedly installed on the side surface of the clamping plate away from the electric push rod.

[0009] Also includes:

[0010] A cleaning component is provided on the other side surface of the connecting frame;

[0011] The cleaning component includes a connecting block that is fixedly connected to the connecting frame;

[0012] The connecting block has a groove inside.

[0013] Preferably, a stepper motor is fixedly mounted on the surface of the connecting block, and a threaded rod is fixedly connected to the output end of the stepper motor through one side surface of the connecting block, and the threaded rod is rotatably connected to the groove.

[0014] Preferably, the threaded rod is threaded with a threaded sleeve, and an mounting plate is symmetrically mounted on the side of the threaded sleeve away from the threaded rod. A cleaning brush is attached to one side of the mounting plate.

[0015] Preferably, a sliding sleeve is attached to the side of the cleaning brush away from the mounting plate, and a sliding rod is connected through the inside of the sliding sleeve. The two sides of the sliding rod are fixedly connected to the groove.

[0016] Preferably, the threaded sleeve and the sliding sleeve are slidably connected to the groove.

[0017] Preferably, threaded inserts are connected through both sides of the mounting plate and the cleaning brush, and nuts are threadedly connected to both sides of the threaded inserts.

[0018] Preferably, the threaded insert and nut are made of stainless steel.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This concrete hardness testing device, by setting a cleaning component, allows for the cleaning of concrete block residues left on the base, thereby facilitating subsequent testing of other concrete blocks. Simultaneously, the engagement between the threaded rod and the nut allows for the replacement of the cleaning brush on the cleaning component. The specific details are as follows:

[0020] 1. By setting up a cleaning component, after the inspected concrete block is removed by the staff, the stepper motor is started via the control terminal, causing the output of the stepper motor to drive the rotation of the threaded rod. As the threaded rod rotates, it drives the movement of the threaded sleeve. At the same time, the mounting block on the threaded sleeve is connected to the cleaning brush through the action of the threaded rod and nut. The other side of the cleaning brush is also connected to the sliding sleeve through the threaded rod and nut. This allows the cleaning brush to be fixedly mounted on the threaded sleeve and the sliding sleeve. The sliding sleeve and the sliding rod are connected through sliding, while the sliding rod is fixedly connected to the groove. This cooperation between the mounting block, the threaded rod, the nut, the cleaning brush, the sliding sleeve, and the sliding rod ensures that the threaded sleeve can move on the threaded rod. As the threaded sleeve moves, it drives the movement of the cleaning brush, thereby cleaning the residue left on the base surface, which facilitates the subsequent inspection of other concrete blocks.

[0021] 2. By setting up electric push rods, clamping plates, and friction pads, after placing the concrete block directly below the testing device, the operation of the electric push rods on both sides is started synchronously through the control terminal, so that the output ends of the two electric push rods extend synchronously, thereby driving the clamping plate and friction pad to move, thus providing a certain clamping effect on the concrete block, which facilitates the testing device to perform strength testing on the concrete block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a concrete hardness testing device, including a base 1, a connecting frame 2 fixedly installed on the top surface of the base 1; a cylinder 3 fixedly installed in the middle of the top surface of the connecting frame 2, a testing device 4 fixedly installed on one side surface of the cylinder 3 passing through the output end of the connecting frame 2, an electric push rod 5 penetratingly connected to both sides of the connecting frame 2 near the bottom, a clamping plate 6 fixedly connected to one side surface of the output end of the electric push rod 5, and a friction pad 7 fixedly installed on the side surface of the clamping plate 6 away from the electric push rod 5; it also includes: a cleaning component 8 provided on the other side surface of the connecting frame 2; wherein, the cleaning component 8 includes a connecting block 801 fixedly connected to the connecting frame 2; wherein, the connecting block 801 has a groove 802 inside, such as Figure 1-5 As shown, by setting up the cleaning component 8, the concrete block residue left on the base 1 can be cleaned, which facilitates the subsequent inspection of other concrete blocks. At the same time, the cleaning brush 807 on the cleaning component 8 can be replaced through the cooperation between the threaded rod 9 and the nut 10. Meanwhile, the cylinder 3 is electrically connected to the control end, and the electric push rod 5 is model LAM33-A. The electric push rod 5 is electrically connected to the control end.

[0030] A stepper motor 803 is fixedly mounted on the surface of the connecting block 801. A threaded rod 804 is fixedly connected to one side of the connecting block 801 through the output end of the stepper motor 803. The threaded rod 804 is rotatably connected to the groove 802. A threaded sleeve 805 is threadedly fitted onto the surface of the threaded rod 804. A mounting plate 806 is symmetrically mounted on the side of the threaded sleeve 805 away from the threaded rod 804. A cleaning brush 807 is attached to one side of the mounting plate 806. A sliding sleeve 808 is attached to the side of the cleaning brush 807 away from the mounting plate 806. A sliding rod 809 is connected through the interior of the sliding sleeve 808. Both sides of the sliding rod 809 are fixedly connected to the groove 802. The threaded sleeve 805 and the sliding sleeve 808 are slidably connected to the groove 802. Threaded insert rods 9 are connected through the surfaces of the mounting plate 806 and the cleaning brush 807. Nuts 10 are threadedly connected to both sides of the threaded insert rods 9. The threaded insert rods 9 and nuts 10 are made of stainless steel. Figure 3-5 As shown, after the inspected concrete block is removed by the staff, the stepper motor 803 is started via the control terminal, causing the output of the stepper motor 803 to drive the rotation of the threaded rod 804. As the threaded rod 804 rotates, it moves the threaded sleeve 805. Simultaneously, the mounting block on the threaded sleeve 805 is connected to the cleaning brush 807 via the threaded insert rod 9 and nut 10. The other side of the cleaning brush 807 is also connected to the sliding sleeve 808 via the threaded insert rod 9 and nut 10. This allows the cleaning brush 807 to be fixedly mounted on the threaded sleeve. On 805 and sliding sleeve 808, sliding sleeve 808 and sliding rod 809 are connected by a through sliding connection, while sliding rod 809 is fixedly connected to groove 802. This allows the threaded sleeve 805 to move on threaded rod 804 through the cooperation between mounting block, threaded rod 9, nut 10, cleaning brush 807, sliding sleeve 808 and sliding rod 809. As threaded sleeve 805 moves, it can drive the cleaning brush 807 to move, thereby cleaning the residue left on the surface of base 1, which facilitates the subsequent inspection of other concrete blocks.

[0031] Working principle: Before using this concrete hardness testing device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5As shown, firstly, by setting up the cleaning component 8, after the inspected concrete block is removed by the staff, the stepper motor 803 is started via the control terminal, causing the output end of the stepper motor 803 to drive the rotation of the threaded rod 804. As the threaded rod 804 rotates, it drives the threaded sleeve 805 to move. At the same time, the mounting block on the threaded sleeve 805 is connected to the cleaning brush 807 through the threaded insert rod 9 and nut 10. Simultaneously, the other side of the cleaning brush 807 is also connected to the sliding sleeve 808 through the threaded insert rod 9 and nut 10. This allows the cleaning brush 807 to be fixed in place. The threaded sleeve 805 and sliding sleeve 808 are fixedly installed on the threaded sleeve 805 and sliding sleeve 808, respectively. The sliding sleeve 808 and sliding rod 809 are connected by a through sliding connection, while the sliding rod 809 is fixedly connected to the groove 802. This allows the threaded sleeve 805 to move on the threaded rod 804 through the cooperation between the mounting block, threaded rod 9, nut 10, cleaning brush 807, sliding sleeve 808 and sliding rod 809. As the threaded sleeve 805 moves, it can drive the cleaning brush 807 to move, thereby cleaning the residue left on the surface of the base 1, which facilitates the subsequent inspection of other concrete blocks.

[0032] Secondly, by setting up electric push rods 5, clamping plates 6 and friction pads 7, after the concrete block is placed directly below the testing device 4, the operation of the electric push rods 5 on both sides is started synchronously through the control terminal, so that the output ends of the two electric push rods 5 extend synchronously, thereby driving the clamping plates 6 and friction pads 7 to move, so that the concrete block can be clamped to a certain extent, thus facilitating the testing device 4 to perform strength testing on the concrete block.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
