Description

Technical Field

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

[0002] The testing equipment is a device used during concrete production to test the performance of set concrete blocks. When using the testing equipment, the set concrete block is placed on top of the connecting box, and then the cylinder drives the extrusion plate to squeeze the top of the concrete block. At the same time, the display screen shows the force applied by the cylinder in real time. When the concrete block breaks, the force displayed on the screen can clearly show the strength of the concrete block.

[0003] The inventors discovered in their daily work that the testing equipment still has at least the following problems: When using the testing equipment, a solidified concrete block is placed on top of the connecting box, and then the cylinder drives the extrusion plate to squeeze the top of the concrete block. At the same time, the display screen shows the force applied by the cylinder in real time. When the concrete block breaks, the force displayed on the screen can well show the strength of the concrete block. However, in actual use, due to long-term use, the bottom of the extrusion plate will be uneven, which will cause the extrusion plate to squeeze the concrete block unevenly, thus affecting the testing of the concrete block's performance to a certain extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete performance testing device for concrete production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete performance testing device for concrete production, comprising a connecting box, a support frame fixedly connected to the top of the connecting box, a cylinder fixedly connected to the top of the support frame, an extrusion plate provided at the bottom of the cylinder, a display screen provided at the top of the connecting box, a connecting device provided at the top of the extrusion plate, a protective device provided on the surface of the support frame, the connecting device comprising a threaded cylinder, the threaded cylinder being rotatably inserted into the top of the extrusion plate, a threaded groove being formed on the bottom surface of the cylinder, the threaded cylinder being threadedly fitted onto the surface of the cylinder with the threaded groove, a support ring being fixedly connected to the surface of the cylinder, a fixing rod being slidably inserted through the bottom of the support ring, and the bottom of the fixing rod being provided at the top of the extrusion plate.

[0006] The effect achieved by the above components is as follows: When using the connecting device, the threaded cylinder is manually threaded onto the surface with the threaded groove at the bottom of the cylinder, and then the fixing rod is passed through the support ring. This allows the extrusion plate to be properly positioned at the bottom of the cylinder, making it easy to replace the extrusion plate and preventing the test results from being affected by unevenness at the bottom of the extrusion plate.

[0007] Preferably, a first damping rod is uniformly fixedly connected to the top of the extrusion plate, the top of the first damping rod is fixedly connected to the bottom of the fixing rod, a first spring is sleeved on the surface of the first damping rod, the bottom of the first spring is fixedly connected to the top of the extrusion plate, the end of the first spring near the first damping rod is fixedly connected to the bottom of the fixing rod, and grooves are uniformly formed on the surface of the fixing rod.

[0008] The effect achieved by the above components is that the fixing rod is pressed away from the compression plate by the first spring, which makes it easier to confine the fixing rod inside the support ring.

[0009] Preferably, a second damping rod is uniformly and fixedly connected to the bottom of the cylinder. An arc plate is fixedly connected to the end of the second damping rod away from the cylinder. A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to one side of the cylinder surface. The end of the second spring near the second damping rod is fixedly connected to one side of the arc plate. One side of the arc plate is slidably connected to the inner wall of the groove.

[0010] The effect achieved by the above components is that the arc plate is pulled towards the cylinder surface by the second spring, thereby causing the arc plate to slide into the inside of the groove, which can effectively restrict the fixing rod inside the support ring.

[0011] Preferably, a rectangular block is fixedly connected to one side of the arc plate, a third damping rod is fixedly connected to the top of the rectangular block, a limit sleeve is fixedly connected to the top of the third damping rod, a third spring is sleeved on the surface of the third damping rod, one end of the third spring is fixedly connected to the top of the rectangular block, the top of the third spring is fixedly connected to the bottom of the limit sleeve, and the limit sleeve is slidably sleeved on the top surface of the arc plate.

[0012] The effect achieved by the above components is as follows: the limiting sleeve is manually placed on the top of the two arc plates, and then the limiting sleeve is pulled towards the top of the rectangular block by the third spring, which can effectively restrict the two arc plates inside the groove.

[0013] Preferably, the protective device includes a protective sleeve, which is slidably fitted onto the surface of the support frame. A limiting groove is formed on the surface of the support frame, and one end of the protective sleeve is slidably connected to the inner wall of the limiting groove.

[0014] The effect achieved by the above components is as follows: when using the protective device, the protective sleeve is manually put on the surface of the support frame, so that the bottom of the protective sleeve is set on the top of the connecting box. In this way, the concrete block can be covered by the protective sleeve, which can prevent debris from flying to a certain extent.

[0015] Preferably, a support plate is fixedly connected to one side of the connecting box, and a threaded rod is rotatably inserted through the bottom of the support plate. The threaded rod is threaded through and inserted into one side of the protective sleeve, and a circular plate is fixedly connected to the bottom of the threaded rod.

[0016] The effect achieved by the above components is that the threaded rod can be manually rotated by the circular plate. Since the threaded rod is threaded through and inserted into one side of the protective sleeve, it can effectively drive the protective sleeve to slide up and down on the surface of the support frame.

[0017] Preferably, a fourth damping rod is fixedly connected to the bottom of one side of the protective sleeve, the bottom of the fourth damping rod is fixedly connected to the top of the connecting box, a fourth spring is sleeved on the surface of the fourth damping rod, one end of the fourth spring is fixedly connected to the top of the connecting box, and the top of the fourth spring is fixedly connected to one side of the protective sleeve.

[0018] The effect achieved by the above components is that the protective sleeve is pressed away from the connecting box by the fourth spring, which can effectively support the end of the protective sleeve away from the threaded rod.

[0019] Preferably, a rectangular frame is fixedly connected to the top of the connecting box, the rectangular frame is slidably fitted onto the bottom surface of the protective sleeve, and a rubber frame is fixedly connected to the inner wall of the top of the rectangular frame.

[0020] The effect achieved by the above components is that when the bottom of the protective sleeve is placed on the top of the connecting box, the rectangular frame is placed on the bottom of the protective sleeve, thereby pressing the rubber frame against the surface of the protective sleeve. This can effectively prevent debris from splashing out from the connection between the protective sleeve and the rectangular frame.

[0021] In this invention, by setting a connecting device, when using the connecting device, the threaded cylinder is manually threaded onto the surface of the cylinder bottom with a threaded groove, and then the fixing rod is passed through the support ring. This allows the extrusion plate to be properly positioned at the bottom of the cylinder, making it easy to replace the extrusion plate and preventing the unevenness of the bottom of the extrusion plate from affecting the test results.

[0027] Example 1, such as Figure 1-4 As shown, a concrete performance testing device for concrete production includes a support frame 2 fixedly connected to the top of a connecting box 1, a cylinder 3 fixedly connected to the top of the support frame 2, an extrusion plate 4 at the bottom of the cylinder 3, a display screen 5 on the top of the connecting box 1, a connecting device 6 on the top of the extrusion plate 4, and a protective device 7 on the surface of the support frame 2. When using the testing device, a solidified concrete block is placed on the top of the connecting box 1, and then the cylinder 3 drives the extrusion plate 4 to extrude the concrete block to the top. At the same time, the force applied by the cylinder 3 is displayed on the display screen 5 in real time. When the concrete block breaks, the force displayed on the display screen 5 can clearly show the strength of the concrete block.

[0028] Reference Figure 2The connecting device 6 includes a threaded cylinder 602, which is rotatably inserted into the top of the extrusion plate 4. A threaded groove 601 is formed on the bottom surface of the cylinder 3. The threaded cylinder 602 is threadedly fitted onto the surface of the cylinder 3 with the threaded groove 601. A support ring 607 is fixedly connected to the surface of the cylinder 3. A fixing rod 605 is slidably inserted through the bottom of the support ring 607. The bottom of the fixing rod 605 is positioned on the top of the extrusion plate 4. When using the connecting device 6, the threaded cylinder 602 is manually threaded onto the surface of the cylinder 3 with the threaded groove 601, and then the fixing rod 605 is passed through the support ring 607. This allows the extrusion plate 4 to be properly positioned at the bottom of the cylinder 3, facilitating the replacement of new extrusion plates. Plate 4 will not be affected by the unevenness of the bottom of the extrusion plate 4. The top of the extrusion plate 4 is uniformly and fixedly connected to a first damping rod 603. The top of the first damping rod 603 is fixedly connected to the bottom of a fixing rod 605. A first spring 604 is sleeved on the surface of the first damping rod 603. The bottom of the first spring 604 is fixedly connected to the top of the extrusion plate 4. One end of the first spring 604 near the first damping rod 603 is fixedly connected to the bottom of the fixing rod 605. The surface of the fixing rod 605 is uniformly provided with grooves 606. The first spring 604 presses the fixing rod 605 away from the extrusion plate 4, which helps to confine the fixing rod 605 inside the support ring 607. The bottom of the cylinder 3 is uniformly... A second damping rod 608 is fixedly connected. An arc plate 610 is fixedly connected to the end of the second damping rod 608 furthest from the cylinder 3. A second spring 609 is sleeved on the surface of the second damping rod 608. One end of the second spring 609 is fixedly connected to one side of the surface of the cylinder 3, and the end of the second spring 609 near the second damping rod 608 is fixedly connected to one side of the arc plate 610. One side of the arc plate 610 is slidably connected to the inner wall of the groove 606. By pulling the arc plate 610 towards the surface of the cylinder 3 through the second spring 609, the arc plate 610 slides into the groove 606. This effectively confines the fixing rod 605 inside the support ring 607. One side of the arc plate 610 is fixed... A rectangular block 611 is connected, and a third damping rod 612 is fixedly connected to the top of the rectangular block 611. A limiting sleeve 614 is fixedly connected to the top of the third damping rod 612. A third spring 613 is sleeved on the surface of the third damping rod 612. One end of the third spring 613 is fixedly connected to the top of the rectangular block 611, and the top of the third spring 613 is fixedly connected to the bottom of the limiting sleeve 614. The limiting sleeve 614 is slidably sleeved on the top surface of the arc plate 610. The limiting sleeve 614 is manually sleeved on the top of the two arc plates 610, and then the limiting sleeve 614 is pulled closer to the top of the rectangular block 611 by the third spring 613. This can effectively restrict the two arc plates 610 inside the groove 606.

[0029] Reference Figure 3 and Figure 4The protective device 7 includes a protective sleeve 701, which is slidably fitted onto the surface of the support frame 2. A limiting groove 702 is formed on the surface of the support frame 2. One end of the protective sleeve 701 is slidably connected to the inner wall of the limiting groove 702. When using the protective device 7, the protective sleeve 701 is manually fitted onto the surface of the support frame 2, so that the bottom of the protective sleeve 701 is positioned at the top of the connecting box 1. This allows the protective sleeve 701 to cover the concrete block, preventing debris from splashing to some extent. A support plate 703 is fixedly connected to one side of the connecting box 1. A threaded rod 704 is rotatably inserted through the bottom of the support plate 703. The threaded rod 704 is threaded through and inserted into one side of the protective sleeve 701. A circular plate 705 is fixedly connected to the bottom of the threaded rod 704. The threaded rod 704 is manually rotated by the circular plate 705. Because the threaded rod 704 is threaded through and inserted into one side of the protective sleeve 701, it can effectively drive the protective sleeve 701 to slide up and down on the surface of the support frame 2. A fourth damping rod 706 is fixedly connected to the bottom. The bottom of the fourth damping rod 706 is fixedly connected to the top of the connecting box 1. A fourth spring 707 is sleeved on the surface of the fourth damping rod 706. One end of the fourth spring 707 is fixedly connected to the top of the connecting box 1, and the top of the fourth spring 707 is fixedly connected to one side of the protective sleeve 701. The protective sleeve 701 is pressed away from the connecting box 1 by the fourth spring 707, which can effectively support the end of the protective sleeve 701 away from the threaded rod 704. A rectangular frame 708 is fixedly connected to the top of the connecting box 1. The rectangular frame 708 is slidably sleeved on the bottom surface of the protective sleeve 701. A rubber frame 709 is fixedly connected to the inner wall of the top of the rectangular frame 708. When the bottom of the protective sleeve 701 is set on the top of the connecting box 1, the rectangular frame 708 is sleeved on the bottom of the protective sleeve 701, which causes the rubber frame 709 to be pressed against the surface of the protective sleeve 701. This can effectively prevent debris from splashing out from the connection between the protective sleeve 701 and the rectangular frame 708.

[0030] Working principle: When using the testing equipment, a solidified concrete block is placed on top of the connecting box 1. The cylinder 3 then drives the extrusion plate 4 to press the concrete block against the top. Simultaneously, the display screen 5 shows the force applied by the cylinder 3 in real time. When the concrete block breaks, the force displayed on the screen 5 clearly indicates the strength of the concrete block. When using the connecting device 6, the threaded cylinder 602 is manually threaded onto the surface of the cylinder 3 where the threaded groove 601 is located. The fixing rod 605 is then passed through the support ring 607. The first spring 604 presses the fixing rod 605 away from the extrusion plate 4, while the second spring 609 pulls the arc plate 610 towards the surface of the cylinder 3, causing the arc plate 610 to slide into the groove 606. This helps to confine the fixing rod 605 within the support ring 607. The limiting sleeve 614 is manually placed on top of the two arc plates 610, and then the third spring 613 pulls it towards the top of the rectangular block 611. The limiting sleeve 614 effectively confines the two arc plates 610 within the groove 606, allowing the extrusion plate 4 to be positioned at the bottom of the cylinder 3. This facilitates replacement of the extrusion plate 4 and prevents unevenness at the bottom of the extrusion plate 4 from affecting the test results. When using the protective device 7, the threaded rod 704 is manually rotated via the circular plate 705. Since the threaded rod 704 is threaded through and inserted into one side of the protective sleeve 701, it effectively drives the protective sleeve 701 to slide up and down on the surface of the support frame 2, positioning the bottom of the protective sleeve 701 at the top of the connecting box 1. When the bottom of the protective sleeve 701 is positioned at the top of the connecting box 1, the rectangular frame 708 is fitted onto the bottom of the protective sleeve 701, causing the rubber frame 709 to press against the surface of the protective sleeve 701. This effectively prevents debris from splashing out from the connection between the protective sleeve 701 and the rectangular frame 708. The protective sleeve 701 can cover the concrete block, thus preventing debris from splashing to a certain extent.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
