Description
Technical Field
[0001] The present application relates to the technical field of concrete pressure testing, and in particular to a concrete strength pressure testing machine. Background Art
[0002] The concrete compression testing machine is a testing machine product that measures and judges the performance parameters of concrete in accordance with the national standard GB / T50081-2002 "Standard for Test Methods of Mechanical Properties of Ordinary Concrete".
[0003] When an existing pressure testing machine performs a pressure test on concrete, after the concrete test block is broken by pressure, the debris generated will be widely and irregularly scattered on the test bench, which will have a direct impact on the cleanliness of the test bench. At the same time, the debris may contain sharp particles, which may cause scratches or wear to the precision parts of the testing machine during the subsequent pressure test, thereby shortening the service life of the equipment. Therefore, after the experiment is completed, the staff needs to clean up the debris. However, the manual cleaning work is slow, which affects the speed of the experiment and is also more physically demanding. Utility Model Content
[0004] In response to the shortcomings of the existing technology, this application provides a concrete strength pressure testing machine with advantages such as automatic cleaning, which solves the problem that staff need to clean up the debris after the experiment is completed. However, the manual cleaning work is slow, which affects the speed of the experiment and is more physically demanding.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a concrete strength pressure testing machine, comprising a base, a load-bearing platform fixedly connected to one side of the upper end of the base, a lower pressure plate fixedly connected to the upper end of the load-bearing platform, a fixed plate connected to one side of the load-bearing platform by bolts, a connecting groove is provided at the upper end of the fixed plate, a guide groove body is rotatably connected to the inside of the connecting groove, a limiting frame is rotatably connected to the middle part of the lower end of the guide groove body, a plurality of limit grooves distributed in a linear array and corresponding to the limit frame are provided inside one side of the fixed plate, and the limit frame extends into the limit groove at one end away from the guide groove body and is slidably connected to the inner wall of the limit groove.
[0006] The upper end of the base is fixedly connected to a mounting bracket near the supporting platform, the upper end of the mounting bracket is fixedly connected to a rodless cylinder, the upper end of the rodless cylinder is fixedly connected to a fixing bracket, one side of the fixing bracket is fixedly connected to a connecting rod, one end of the connecting rod is connected to a push plate by a bolt, and the lower end surface of the push plate and the upper end surface of the lower pressure plate are on the same horizontal plane.
[0007] Through the above scheme, a fixed frame is set at the upper end of the rodless cylinder, a connecting rod is set on one side of the fixed frame, a push plate is set at one end of the connecting rod, and a guide groove body is rotatably set inside the connecting groove. When the test is completed, the rodless cylinder is started, and the rodless cylinder will drive the fixed frame to move, and then drive the push plate to move through the connecting rod to push the debris onto the guide groove body, and then roll it into the external collection box. There is no need for manual cleaning by the staff. At the same time, the cleaning process is relatively simple, which can increase the cleaning speed, further speed up the test speed, and reduce the labor intensity of the staff. At the same time, by adjusting the position of the limit frame during use, the limit frame is located in the limit groove at different positions, the inclination angle of the guide groove body can be adjusted, and the height of the end of the guide groove body can be further adjusted to suit use in different scenarios.
[0008] Furthermore, an installation groove is opened inside the supporting platform, and a bidirectional screw rod is rotatably connected to one end of the installation groove. A rotating handle corresponding to the bidirectional screw rod is rotatably connected to the supporting platform, and one end of the rotating handle extends into the installation groove and is fixedly connected to one end of the bidirectional screw rod.

Both ends of the two movable frames extend out of the installation groove and are fixedly connected with a baffle.
[0011] Through the above solution, when the bidirectional screw rotates, the two moving frames will move towards or oppositely. The two baffles can prevent the concrete test block from splashing to both sides during the test and can also play a role in positioning the concrete test block.
[0012] Furthermore, both sides of the support platform are fixedly connected with slide rails corresponding to the mobile rack, and two slide rail surfaces are slidably sleeved with two mirror-distributed sliders, and the four slider surfaces are fixedly connected with the corresponding mobile rack surfaces.

[0014] Furthermore, a guide plate is fixedly connected to the lower pressure plate on one side close to the guide groove body.
[0015] With the above solution, the guide plate is located at the upper end of the slide rail close to the guide groove body, so when in use, it can prevent the pushed-out debris from falling onto the slide rail and affecting the use of the slide rail and the slider.
[0016] Furthermore, the upper end of the base is fixedly connected to two support frames distributed in a mirror image, the upper ends of the two support frames are commonly fixedly connected to a mounting plate, the lower end of the mounting plate is fixedly connected to a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is connected to an upper pressure plate by bolts.
[0017] Through the above scheme, when the hydraulic cylinder is started during use, the hydraulic cylinder will drive the upper pressure plate to move downward, thereby applying pressure to the concrete test block. The telescopic end of the hydraulic cylinder is connected to the upper pressure plate by bolts, so the upper pressure plate can be disassembled and replaced more conveniently to suit concrete test blocks of different specifications.
[0018] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

When the test is completed, the rodless cylinder is started, the rodless cylinder drives the fixing frame to move, and then drives the push plate to move through the connecting rod, pushing the debris onto the guide groove body, and then rolling it into an external collection box, without the need for manual cleaning by staff. At the same time, the cleaning process is relatively simple, which can increase the cleaning speed, further speed up the test speed, and reduce the labor intensity of staff. At the same time, when in use, by adjusting the position of the limit frame so that the limit frame is inside the limit groove at different positions, the inclination angle of the guide groove body can be adjusted, and the height of the end of the guide groove body can be further adjusted to be suitable for use in different scenarios.

The upper end of the rodless cylinder 17 is fixedly connected to the fixing frame 18. One side of the fixing frame 18 is fixedly connected to a connecting rod 19. One end of the connecting rod 19 is connected to a push plate 20 by a bolt. The lower end surface of the push plate 20 and the upper end surface of the lower pressure plate 3 are on the same horizontal plane.
[0029] See also Figure 2The support platform 2 is provided with a mounting groove 4, and one end of the mounting groove 4 is rotatably connected to a bidirectional screw rod 5. The support platform 2 is rotatably connected to a rotating handle 6 corresponding to the bidirectional screw rod 5. One end of the rotating handle 6 extends into the mounting groove 4 and is fixedly connected to one end of the bidirectional screw rod 5. When the rotating handle 6 is rotated during use, the rotating handle 6 will drive the bidirectional screw rod 5 to rotate synchronously.

[0032] The working principle of the above embodiment is:
[0033] First, place the concrete test block on the lower pressure plate 3 on the bearing platform 2, and rotate the rotating handle 6, which drives the bidirectional screw rod 5 to rotate, thereby causing the two mobile frames 7 to move toward each other in the installation groove 4, and the baffles 8 at both ends of the mobile frame 7 also move accordingly, until the two sides of the concrete test block are clamped to achieve the positioning of the test block and prevent the test block from splashing or moving during the test. Start the hydraulic cylinder 23, and the telescopic end of the hydraulic cylinder 23 drives the upper pressure plate 24 to move downward until it contacts the concrete test block and applies pressure to it. As the hydraulic cylinder 23 continues to work, the pressure The force gradually increases until it reaches the predetermined test pressure value. When the concrete test block is broken under the pressure, the hydraulic cylinder 23 is closed, the pressure application is stopped, and the rodless cylinder 17 is started. The rodless cylinder 17 drives the fixed frame 18 to move, and then pushes the push plate 20 to move toward the guide groove 13 through the connecting rod 19. The push plate 20 pushes the debris on the supporting platform 2 toward the guide groove 13. The debris rolls along the guide groove 13 and finally falls into the external collection box. The setting of the guide plate 11 prevents the debris from falling onto the slide rail 9, thereby protecting the normal use of the slide rail 9 and the slider 10.
