Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a testing device for concrete. Background Technology

[0002] In existing concrete testing work, workers often need to bend over to perform operations. For example, in the testing of road and bridge concrete structures or other concrete strength testing scenarios, traditional testing methods require workers to be in close contact with the testing points. Frequent bending over not only increases the labor intensity of workers but also easily leads to physical fatigue and injury. Maintaining a bent-over posture for extended periods during testing may also affect the accuracy and efficiency of the tests. In addition, some testing environments may be harsh, such as uneven ground or dusty conditions, exacerbating the inconvenience and health risks for workers. Therefore, we propose a concrete testing device to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing device for concrete.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A testing device for concrete includes a support column, three inclined support rods fixed at equal intervals around the lower end of the support column, universal wheels rotatably connected to the lower ends of the support rods, a movable rod passing through the support column, a rotating rod rotatably connected to one side of the upper end of the movable rod, a limit rod rotatably connected to the rotating rod, the upper end of the limit rod rotatably connected to one side of the upper end of the support column, a handle fixed to one end of the rotating rod, a baffle fixed to the lower end of the movable rod, and a concrete rebound hammer detachably mounted on one side of the baffle.

[0006] Preferably, a slot is provided on one side of the supporting column, and an opening is provided at the lower end of the slot, through which the moving rod passes and is engaged in the slot.

[0007] Preferably, the baffle is fixed to the lower end of the moving rod by two screws.

[0008] Preferably, a fixing member is fixed to one side of the upper end of the bearing column, and the end of the limiting rod away from the rotating rod is rotatably connected to the fixing member.

[0009] Preferably, a rubber pad is fixed to the lower end of the moving rod, one side of the concrete rebound hammer abuts against the baffle, and one end of the concrete rebound hammer abuts against the rubber pad.

[0010] Preferably, two binding straps are connected to one side of the baffle, and the concrete rebound hammer is bound to the baffle by the two binding straps.

[0011] In this utility model, during testing:

[0012] 1. Device movement: Staff can easily move the entire testing device to the concrete structure to be tested using the casters at the bottom of the device. The casters design allows the device to move flexibly in different terrains and testing sites, improving the convenience of testing.

[0013] 2. Instrument installation: Beforehand, place the upper end of the concrete rebound hammer against the lower end of the rubber pad. The rubber pad acts as a buffer and protector to prevent the rebound hammer from being damaged by direct collision with the device. Then, use the binding straps to tie and fix the concrete rebound hammer to ensure that it will not shake or fall off during the testing process.

[0014] 3. Testing Operation: The operator holds the handle and pulls the rotating rod upward. The movement of the rotating rod, through the linkage of the limit rod, drives the moving rod to descend, thereby bringing the lower end of the concrete rebound hammer against the surface of the concrete structure. At this time, the concrete rebound hammer starts to work and tests the strength of the concrete.

[0015] 4. Data Recording and Analysis: After the test is completed, the staff uses a handheld receiver to display and record the data displayed by the concrete rebound hammer, and analyzes this data. Through professional analysis methods, the strength and quality of the concrete structure are evaluated, providing a scientific basis for the quality of the project.

[0016] 5. Position transfer: After completing the test at one test point, the staff moves the rotating rod up and down to raise the moving rod, so that the concrete rebound hammer leaves the concrete surface. The universal wheels are then used to move the device to the next test point, and the above test steps are repeated.

[0017] This utility model has the following advantages:

[0018] 1. It avoids the need for staff to frequently bend over, greatly reducing the burden on the lower back. Staff can operate upright, putting their bodies in a more comfortable position, reducing the risk of physical fatigue and injury, and improving work comfort.

[0019] 2. It is easy to move and can quickly reach various testing points, reducing the time spent moving between different testing points. Moreover, the operation process is simpler and smoother, reducing the inconvenience and time waste caused by bending over, thereby improving the overall testing efficiency.

[0020] 3. When operators are in an upright position, their vision is clearer and their operating space is larger, allowing them to more accurately place the rebound hammer into contact with the test point. This reduces the impact of human factors on the test results and improves the accuracy of the test.

[0021] 4. In harsh testing environments, such as uneven ground or contaminants, the device can be moved flexibly by means of casters, avoiding direct contact between staff and the adverse environment, reducing health risks, and ensuring the smooth progress of testing work.

[0022] In summary, this utility model avoids frequent bending over for operators, greatly reducing the burden on the lower back. Operators can operate upright, putting their bodies in a more comfortable posture, reducing the risk of physical fatigue and injury, and improving work comfort. It is also easy to move, allowing for quick access to various testing points, reducing the time spent moving between different testing points. Moreover, the operation process is simpler and smoother, reducing the inconvenience and time wasted due to bending over, thereby improving overall testing efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-4 A testing device for concrete includes a support column 5, with three inclined support rods 8 fixed at equal intervals around the lower end of the support column 5. The three inclined support rods 8 are evenly distributed at 120°, which not only provides stable support for the support column 5, but also effectively distributes the weight of the device itself, preventing it from tipping over during movement or testing.

[0030] The lower end of the support rod 8 is rotatably connected to a caster wheel 10, which can rotate freely 360° and move flexibly in different terrains and testing sites. During the movement, the staff can adjust the pushing force and direction according to the actual situation.

[0031] A movable rod 7 is installed through the support column 5. A rotating rod 3 is rotatably connected to the upper end of the movable rod 7. A limiting rod 2 is rotatably connected to the rotating rod 3. The upper end of the limiting rod 2 is rotatably connected to the upper end of the support column 5. A handle 4 is fixed to one end of the rotating rod 3. A baffle 11 is fixed to the lower end of the movable rod 7. A concrete rebound hammer 15 is detachably installed on one side of the baffle 11. The receiver transmits data with the concrete rebound hammer 15 through wireless communication technology to ensure the real-time performance and accuracy of the data. When recording data, the staff should carefully check the data displayed by the receiver to avoid recording errors. At the same time, the receiver can also store a large amount of test data for convenient subsequent query and analysis.

[0032] A slot 6 is provided on one side of the support column 5, and an opening 14 is provided at the lower end of the slot 6. The moving rod 7 passes through the opening 14 and is engaged in the slot 6. The design of the slot 6 provides a precise moving track for the moving rod 7, ensuring that the moving rod 7 will not deviate during the up and down movement. At the same time, the size of the opening 14 is adapted to the moving rod 7, which not only ensures that the moving rod 7 can pass smoothly, but also prevents it from shaking.

[0033] The baffle 11 is fixed to the lower end of the moving rod 7 by two screws 12. The fixing method of the screws 12 makes the connection between the baffle 11 and the moving rod 7 firm and reliable, and also facilitates disassembly and replacement in the future. When the baffle 11 is damaged or needs maintenance, the staff can easily disassemble it.

[0034] A fixing member 1 is fixed on one side of the upper end of the bearing column 5. The end of the limiting rod 2 away from the rotating rod 3 is rotatably connected to the fixing member 1. The fixing member 1 provides a stable rotation fulcrum for the limiting rod 2, so that an effective linkage mechanism can be formed between the rotating rod 3, the limiting rod 2 and the moving rod 7, ensuring that the movement of the rotating rod 3 can be accurately transmitted to the moving rod 7.

[0035] A rubber pad 13 is fixed to the lower end of the moving rod 7. One side of the concrete rebound hammer 15 abuts against the baffle 11, and one end of the concrete rebound hammer 15 abuts against the rubber pad 13. The material of the rubber pad 13 has good elasticity and wear resistance, and can effectively absorb the impact force generated by the rebound hammer during installation.

[0036] Two binding straps 9 are connected to one side of the baffle 11, and the concrete rebound hammer 15 is bound to the baffle 11 by the two binding straps 9.

[0037] In this utility model, during testing:

[0038] 1. Device movement: The staff can easily push the entire testing device to the concrete structure to be tested using the casters 10 at the bottom of the device. The design of the casters 10 allows the device to move flexibly in different terrains and testing sites, improving the convenience of testing.

[0039] 2. Instrument installation: Beforehand, place the upper end of the concrete rebound hammer 15 against the lower end of the rubber pad 13. The rubber pad 13 plays a buffering and protective role to prevent the rebound hammer from being damaged by direct collision with the device. Then, use the binding strap 9 to bind and fix the concrete rebound hammer 15 to ensure that the concrete rebound hammer 15 will not shake or fall off during the test.

[0040] 3. Testing Operation: The operator holds the supporting column 5 with one hand to make it firmly fixed, and holds the handle 4 with the other hand to pull the rotating rod 3 upward. The movement of the rotating rod 3, through the linkage of the limiting rod 2, drives the moving rod 7 to descend, so that the lower end of the concrete rebound hammer 15 is pressed against the surface of the concrete structure. At this time, the concrete rebound hammer 15 starts to work and tests the strength of the concrete.

[0041] 4. Data Recording and Analysis: After the test is completed, the staff will use a handheld receiver to display and record the data displayed by the concrete rebound hammer 15. The data will be recorded and stored. Through professional analysis methods, the strength and quality of the concrete structure will be evaluated to provide a scientific basis for the quality of the project.

[0042] 5. Position transfer: After completing the test at one test point, the staff moves the rotating rod 3 up and down to raise the moving rod 7, so that the concrete rebound hammer 15 leaves the concrete surface. The universal wheels 10 are then used to move the device to the next test point, and the above test steps are repeated.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
