[0002] Before the use of concrete, it is necessary to detect its compressive strength to prevent non-compliance. The traditional method for detecting the compressive strength of concrete usually adopts manual operation. The concrete block is placed on the detection equipment, and the compressive strength is tested by applying pressure. However, this method has the problems of cumbersome operation, low test efficiency, and large human error, and it is difficult to meet the requirements of accuracy and high efficiency for the detection of the compressive strength of concrete in modern construction projects. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems existing in the prior art that the manual operation method has cumbersome operation, low test efficiency, and large human error, and it is difficult to meet the requirements of accuracy and high efficiency for the detection of the compressive strength of concrete in modern construction projects, and a detection device for the compressive strength of concrete is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Two guide rails are fixedly connected to the bottom of the base, and a load-bearing plate is slidably connected in the two guide rails;

[0007] Two sets of lifting components are respectively arranged inside the mounting frames, and the lifting components are used to drive the lifting of the concrete block.

[0008] In a possible design, the lifting component includes a lead screw, the lead screw is rotatably connected inside the mounting frame, a first motor is fixedly connected to the upper surface of the mounting frame, one end of the output shaft of the first motor is fixedly connected to the lead screw, a lifting plate is slidably connected inside the mounting frame, and the lead screw is threadedly connected to the lifting plate.

[0009] In a possible design, two bidirectional screws are rotatably connected between the two lifting plates, and two symmetrically arranged clamping plates are threadedly connected between the two bidirectional screws. The two clamping plates are used for clamping concrete blocks. A second motor is fixedly connected to the upper surface of one of the lifting plates, and one end of the output shaft of the second motor is fixedly connected to one of the bidirectional screws. Synchronous wheels are fixedly connected to the same ends of the two bidirectional screws, and the two synchronous wheels are connected by a synchronous belt.

[0010] In a possible design, two fixed rods are respectively fixedly connected inside the mounting frame. The two fixed rods are respectively located on both sides of the lead screw, and both fixed rods are slidably connected to the lifting plate.

[0011] In a possible design, a pressure sensor is fixedly connected to the bottom of the pressure plate, and the pressure sensor is in contact with the concrete block.

[0012] In a possible design, screws are respectively threadedly connected to the four corners of the base, and stabilizing legs are respectively rotatably connected to the bottoms of the screws.

[0013] In this application, during use, first move the detection device to the concrete, then control the first motor to rotate the lead screw, drive the lifting plate and the clamping plate to move downward. After moving to an appropriate height, control the second motor to make the two clamping plates approach each other to clamp the concrete block. Then, install the load-bearing plate in the guide rail, place the concrete block on the load-bearing plate, and then start the cylinder to drive the piston rod to drive the pressure plate to move downward to apply pressure to the concrete block. During the pressure application process, the pressure sensor will monitor the pressure received by the concrete block in real time. When the pressure reaches the preset value, the control system will control the cylinder to stop moving, thereby completing the detection of the compressive strength of the concrete. Finally, control the second motor to make the two clamping plates move away from each other to release the concrete block, completing the entire detection process.

A first motor 11 is fixedly connected to the upper surface of the mounting frame 2, and the output shaft of the first motor 11 is fixedly connected to the lead screw 9. Therefore, when the first motor 11 rotates, it can drive the lead screw 9 to rotate. A lifting plate 16 is also slidably connected inside the mounting frame 2, and the lead screw 9 is threadedly connected to the lifting plate 16. Therefore, when the lead screw 9 rotates, it can drive the lifting plate 16 to move up and down inside the mounting frame 2;

[0025] Between the two lifting plates 16, two bidirectional screws 18 are rotatably connected. Two symmetrically arranged clamping plates 7 are threadedly connected between the two bidirectional screws 18. These two clamping plates 7 are used to clamp the concrete blocks.

A synchronous wheel 17 is fixedly connected to the same end of each of the two bidirectional screws 18, and the two synchronous wheels 17 are connected by a synchronous belt. Therefore, when the second motor 12 rotates, the two bidirectional screws 18 will rotate synchronously, thereby driving the two clamping plates 7 to approach or separate from each other, realizing the clamping and release of the concrete blocks.
