[0002] The rebound hammer is a device used to test the hardness and elasticity of materials. It is often used in concrete strength testing in building construction projects. The specific operation of the rebound hammer is to press the impact rod of the rebound hammer against the surface of the concrete to be tested, and ensure that the central axis of the rebound hammer is always perpendicular to the concrete surface and not skewed. Then press and push the rebound hammer, and the value can be detected when it is retracted and restored. During the test, it is necessary to test at different positions on each test point, and the average value of the rebound value obtained is used as the final test value of the test point.

[0024] Reference Figure 1-4 A concrete strength testing device for building construction projects includes a U-shaped frame 1 with a cylinder 2 vertically fixed to the top of the U-shaped frame 1, which serves as a support. A rebound hammer body 3 is coaxially mounted inside the cylinder 2. The rebound hammer body 3 is slidably connected to the inside of the cylinder 2 via a connecting mechanism, allowing the rebound hammer body 3 to move telescopically. A drive mechanism for reciprocatingly driving the rebound hammer body 3 is provided at the bottom of the U-shaped frame 1. A rod mechanism is provided at the bottom of the U-shaped frame 1, and a push rod mechanism is provided at the top of the U-shaped frame 1.

[0025] For the above example, those skilled in the art should know that when implementing the above technical solution, the rebound hammer body 3 is a common handheld rebound hammer device, which is cylindrical as a whole and can be an existing rebound hammer device capable of wirelessly transmitting detection values, or a rebound hammer device capable of wired transmission of detection values.

[0026] As a technical optimization solution of the present invention, the connection mechanism includes a connection frame 4, and the rebound hammer body 3 is detachably fixedly arranged inside the connection frame 4. The connection frame 4 is coaxial with the interior of the cylinder 2 and slides with the interior of the cylinder 2. The connection frame 4 is arranged to enclose the rebound hammer body 3, and the rebound hammer body 3 can be removed and used separately.

[0027] As a technical optimization solution of the present invention, the driving mechanism includes a motor 5 fixedly arranged at the bottom of the U-shaped frame 1. The motor 5 is coaxially fixed with a turntable 6. The turntable 6 is rotatably connected to the side away from the circle with a connecting rod 7. The bottom of the connecting frame 4 is coaxially corresponding and detachably connected to a round rod 8. The bottom end of the round rod 8 is detachably and rotatably connected to the connecting rod 7 through a latch 14. A through hole 15 corresponding to the latch 14 is provided on one side of the U-shaped frame 1. The through hole 15 facilitates the removal of the latch 14, thereby facilitating the removal of the round rod 8. By starting the motor 5, the motor 5 can accurately drive the turntable 6 to rotate, and the turntable 6 drives the connecting rod 7 to move along the turntable 6. The connecting rod 7 acts on the round rod 8, causing the round rod 8 to slide along the circular hole 13 of the support block 9. The movement of the connecting rod 7 can drive the round rod 8 to reciprocate, thereby driving the connecting frame 4 and the rebound test body 3 to reciprocate, that is, the rebound test body 3 reciprocates in the cylinder 2.

[0028] As a technical optimization solution of the present invention, a support block 9 is fixed inside the U-shaped frame 1. One end of the support block 9 is provided with a circular hole 13, through which the round rod 8 can slide. The support block 9 stabilizes the round rod 8 and can be used to assist the cylinder 2 to further stabilize the round rod 8.

[0029] As a technical optimization solution of the present invention, a striking rod is provided at one end of the rebound hammer body 3 , and the striking rod is located at the end of the rebound hammer body 3 away from the motor 5 .

[0030] As a technical optimization solution of the present invention, the rod mechanism includes a multi-section telescopic rod 10, the bottom of which is universally connected to a support plate 11 via a ball shaft, and the top of which is fixedly connected to the bottom of the U-shaped frame 1. The angle of the support plate 11 can be adjusted via the ball shaft.

[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, the multi-section telescopic rod 10 can be set to at least two telescopic sections, and each telescopic section of the multi-section telescopic rod 10 is matched with a fastening knob. After the multi-section telescopic rod 10 is extended and retracted, it can be positioned and fixed by the corresponding fastening knob.

[0032] As a technical optimization solution of the present invention, the push rod mechanism includes two electric push rods 12, which are symmetrically fixed on either side of the top of the U-shaped frame 1 and aligned parallel to the impact rod of the rebound hammer body 3. When the two electric push rods 12 are activated, they extend and press against the roof of the house, ultimately securing the multi-section telescopic rod 10 between the floor and the roof. The two electric push rods 12 provide symmetrical and stable support.

[0033] For the above examples, those skilled in the art should know that when implementing the above technical solutions, the relevant electrical devices are all controlled by a control module, that is, a controller. The controller can be set in the middle of the multi-section telescopic rod 10 to facilitate operation by the staff.

[0034] In the present invention, the working principle of the device is as follows:

[0035] When testing the roof inside a house, the multi-section telescopic rod 10 is vertically set on the floor of the house so that the support plate 11 is in contact with the ground. Then, the length of the multi-section telescopic rod 10 is adjusted according to the height inside the house. After adjusting to the appropriate height, the fastening knob on the multi-section telescopic rod 10 is used to position and fix it. Then, the multi-section telescopic rod 10 is moved so that the rebound test body 3 corresponds to the position to be tested, and the two electric push rods 12 are started. The two electric push rods 12 extend and press against the roof inside the house, so that the multi-section telescopic rod 10 is fixed between the floor of the house and the roof inside the house. At this time, the impact rod of the rebound test body 3 is just vertically aligned with the roof inside the house without squeezing or pressing against it. After that, the motor 5 can be started, and the motor 5 accurately drives the turntable 6 to rotate, and the turntable 6 drives the connecting rod 7 to move along the turntable 6. The connecting rod 7 acts on the round rod 8, so that the round rod 8 slides along the round hole 13 of the support block 9. The action of the connecting rod 7 can drive the round rod 8 to move back and forth, and then drive the connecting frame 4 and the rebound hammer body 3 to move back and forth, that is, the rebound hammer body 3 moves back and forth in the cylinder 2, and finally pushes the rebound hammer body 3 and retracts and repositions the rebound hammer body 3, so that the impact rod squeezes the concrete surface, and finally obtains the strength test value. The whole operation does not require the staff to climb up to operate, the operation is simple and convenient, and the detection efficiency is effectively improved.

[0036] During the above operation, the support plate 11 can be rotated by the ball shaft, effectively ensuring that the rebound hammer body 3 can be perpendicular to the concrete plane.

[0037] During the above-mentioned testing process, multiple points can be tested. That is, after testing a point, the multi-section telescopic rod 10 is changed to a new position, that is, the two electric push rods 12 are controlled to retract, and the multi-section telescopic rod 10 is moved again so that the rebound hammer body 3 corresponds to the next position to be tested. The multi-section telescopic rod 10 is then fixed between the floor and the ceiling of the house, and the subsequent testing operation can be carried out. At the same time, when testing at a point, that is, when performing a test, it is only necessary to control the rebound hammer body 3 to move back and forth once, that is, the motor 5 rotates the turntable 6 a set number of circles, so that the rebound hammer body 3 retracts after being pushed, and the pushing speed can be set to a set appropriate speed. Compared with manual pushing testing operations, the method is more standardized and accurate. At the same time, the rebound hammer body 3 can be taken out and used separately, and the overall use effect is flexible.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
