[0017] In the above technical solution, the beneficial effects of the present invention are:

[0018] The cement-based grouting strength detection device has the advantage of improving the accuracy of strength detection. The rebound hammer can make the force of the hammer on the outer shell act on the spring arc plate during the falling process through the setting of the spring arc plate when the hammer rebounds, thereby reducing the energy loss during the falling process of the hammer and improving the accuracy of cement strength detection. At the same time, through the setting of the buffer plate, the offset force exerted on the hammer in a single direction can be dispersed to other directions, thereby further reducing the energy loss during the falling process of the hammer and improving the accuracy of cement strength detection.

[0019] The cement-based grouting strength detection device has the advantage of balancing the offset forces received at relative positions. Through the arrangement of spring one and the shock-absorbing ball, when the offset force received by the spring hammer in a single direction exceeds a limit value, it can be transmitted to the spring arc plate at the other end through spring one and the shock-absorbing ball, so that the forces at both ends of the spring hammer are kept balanced. At the same time, through the arrangement of the buffer plate, the force received can be transmitted to both sides, so that the forces around the spring hammer are balanced, thereby reducing the friction between the spring hammer and the center guide rod, reducing the energy loss when the spring hammer rebounds, and improving the accuracy of strength detection.

[0020] The cement-based grouting strength detection device has the advantage of complementary forces in relative positions. Through the setting of the hanging plate and the wedge block, when the spring arc plate on one side of the impact hammer is damaged and the cylindrical sleeves at the opposite ends push the wedge block to move different distances, the wedge block at one end will engage with the hanging plate, thereby causing the shock-absorbing ball to deviate to the damaged side to achieve the purpose of balanced forces on both sides. At the same time, the damaged spring arc plate can also be quickly judged and replaced, so that the rebound tester can always maintain the best detection state.

[0021] In summary, the present invention can improve the accuracy of strength detection in cement-based detection devices. Through the arrangement of the spring arc plate and the buffer plate, the rebound process of the spring hammer can be prevented from being offset. Through the arrangement of the shock-absorbing ball and the spring one, the forces on the two sides of the spring hammer can be balanced, thereby reducing the energy loss during rebound. At the same time, through the arrangement of the wedge block and the hanging plate, the elastic force of one side of the damaged spring arc plate can be supplemented, thereby increasing the service life of the device. At the same time, the damaged spring arc plate can be quickly judged and replaced, so that the rebound hammer can always maintain the best detection state.

Specifically, the setting of spring 1 can, on the one hand, balance the forces exerted on the spring arc plates 35 on the opposite sides.

The setting of the push rod and the cylindrical sleeve 38 can provide power for the wedge block 47. The setting of spring 2 can make the displacement distances of the wedge blocks 47 on the opposite sides the same when the spring arc plates 35 are intact. When one side of the spring arc plates 35 is damaged, the wedge block 47 will engage with the hanging plate 42, thereby causing the shock-absorbing ball 34 to deviate to one side, so that the damaged spring arc plates 35 can be quickly judged and replaced.

[0053] In the present invention, a cement-based grouting strength detection device has the following specific operating steps:

[0054] When fixing, move the outer supporting frame 1 and the inner supporting frame 2 to the cement base to be inspected, and then quickly push the outer supporting frame 1. The moving block pushes the traceless nail 6 to move in the slide rail groove 4 through the slider 5. When the traceless nail 6 moves to the end of the slide rail groove 4, the traceless nail 6 uses the sharp front end of the traceless nail 6 to fix the entire device on the cement base.

[0055] When initially inspecting and trimming the cement base: start the infrared lamp on the inner support frame 2, and use the infrared lamp light to detect the flatness of the cement base in the area framed by the inner support frame 2. If the surface of the cement base is uneven, the signal receiver 9 receives the signal and starts the electric slide rail 3, so that the sliding sleeve 8 drives the electric push rod 10 and its connecting parts to move to the specified position, and starts the electric push rod 10 and the motor 15. The driving end of the motor 15 drives the grinding disc 16 to rotate, and the electric push rod 10 pushes the grinding disc 16 to approach the cement base and grind it.

[0056] During cement-based strength testing, the electric slide rail 3 drives the electric push rod 2 12 and its connecting parts to move to a designated point through the sliding sleeve 2 11, and the electric push rod 2 12 is started, and the electric push rod 2 12 pushes the rebound hammer. Under the action of the damping rod 14 on the housing 17, the rebound hammer as a whole moves downward vertically to the cement-based surface slowly. When the impact rod 18 contacts the cement-based surface, the impact rod 18 pushes the buffer spring 25, the buffer spring 25 pushes the impact hammer 24, the impact hammer 24 pushes the impact tension spring 21, and drives the limit block 37 through the annular plate 33. Moving on the slide groove 23, the impact hammer 24 drives the slide pointer 22 to move on the vertical rod. When the top hook 20 contacts the hook 29, the top hook 20 pushes the hook 29 to deflect on the rotating component 26, so that the hook 29 is separated from the annular groove plate 27. At the same time, the hook 29 is engaged in the circular groove at the bending part, and the pressure pin 30 pulls the vertical rod to separate the engaging component from the arc groove on the shock-absorbing ball 34. At the same time, the center guide rod 28 is separated from the impact hammer 24. The impact hammer 24 is pushed by the elastic potential energy of the impact tension spring 21 to drive the impact rod 18 to recover.

[0057] During rebound, the limit block 37 is subjected to the squeezing force of the shell 17 by the spring hammer 24, and reacts to the spring arc plate 35. The spring arc plate 35 disperses the force to the spring arc plates 35 on both sides through the buffer plates 36 on both sides. At the same time, the spring 1 in the slide bar 39 balances the force on the spring arc plates 35 in the relative position through the shock-absorbing ball 34, thereby reducing the loss of elastic potential energy of the spring tension spring 21 and improving the detection accuracy. When the spring arc plate 35 is deformed, the cylindrical sleeve 38 is pushed by the two push rods, and the cylindrical sleeve 38 pushes the wedge block 47 and the rolling gear below it to move on the tooth plate groove 45. The rolling gear drives the bevel gear 2 to rotate through the rotating shaft, and the bevel gear 2 drives the telescopic rod 46 to rotate through the bevel gear 1. The telescopic rod 46 drives the cylinder to rotate through the gear set 41, and the cylinder drives the hanging plate 42 to rotate. At the same time, the wedge blocks 47 on both sides squeeze the compression spring 44 between each other to achieve force balance on both sides and maintain the stability of the spring hammer 24 when it falls.

[0058] When the spring arc plate 35 is damaged during rebound, the wedges 47 on both sides of the relative position do not move or are slightly displaced during the movement because the spring arc plate 35 on one side cannot provide power, causing the compression spring 44 to shift to one side, and the hanging plate 42 on the opposite side cannot rotate, so that the wedge 47 on the other side is engaged with the hanging plate 42, so that the shock-absorbing ball 34 is biased toward the damaged side, providing it with sufficient elastic force, reducing the displacement of the impact hammer 24, and increasing its practical life. At the same time, it is also convenient to determine and replace the damaged spring arc plate 35.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
