DETAILED DESCRIPTION

[0022] The technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] In the description of the utility model, it is understood that the position description, such as the position or location relationship of the indication of up, down, front, back, left, right, etc. is based on the position or location relationship shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as the limitation of the utility model.

[0024] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be understood broadly, and the person skilled in the art can determine the specific meaning of the above words in the utility model in combination with the specific content of the technical scheme

[0025] In combination with Figures 1-6A convenient self-vibrating concrete crack resistance test mold includes a support leg 1, a mounting plate 4, and a connector 7. A demolding mechanism 5 is fixedly installed on the top surface of the mounting plate 4, and an induction block mounting mechanism 6 is provided inside the demolding mechanism 5. The demolding mechanism 5 includes a power unit and a vibration unit. The power unit includes a cylinder 501, and the vibration unit includes a mold 506. A fixing block 501 is fixedly installed on the top surface of the mounting plate 4. A cylinder 502 is fixedly installed on the side of the fixing block 501. A base plate 503 is fixedly installed on the top surface of the cylinder 502. A top rod 504 is fixedly installed on the top surface of the base plate 503. A limit ring 505 is fixedly installed on the side of the top rod 504. A fixing component 507 is fixedly installed on the side of the mold 506. A vibration motor 508 is fixedly installed on the side of the fixing component 507. A rubber plate 509 is fixedly installed on the bottom surface of the mold 506.

[0026] Specifically, after adding concrete into the mold 506, the vibration motor 508 is turned on, causing the vibration motor 508 to vibrate the concrete and expel the internal air. After vibration, the concrete is allowed to dry. Once dry, the cylinder 502 is turned on, which pushes the push rod, thereby raising the base plate 503 and further pushing the top rod 504. At this point, the concrete block can be pushed out of the mold 506, completing the demolding operation. The concrete block is then inspected for cracking. By setting multiple sets of vibration motors and molds, the vibration frequency and duration can be controlled, allowing for reasonable control of variables, thereby increasing the comparison and improving the inspection quality of the concrete block.

[0027] See Figure 5 Furthermore, the guide block installation mechanism 6 includes a stress-inducing block 601. A handle 603 is fixedly installed on the bottom end face of the stress-inducing block 601. The mold 506 has an installation groove and a through hole extending through its upper and lower parts. The inner wall of the installation groove is adapted to the side of the stress-inducing block 601, and the inner wall of the through hole is adapted to the side of the push rod 504. A through hole is provided through the side of the mold. An insertion hole 602 is fixedly provided on the side of the stress-inducing block 601. A pin 604 is slidably installed on the inner wall of the insertion hole 602. A handle 605 is fixedly installed on the end face of the pin 604. The pin 604 is slidably connected to the inner wall of the through hole on the side of the mold 506. An anti-slip pad 2 is fixedly installed on the bottom end face of the support leg 1. A reinforcing rib 3 is fixedly installed on the side of the support leg 1. An installation plate 4 is fixedly installed on the inner wall of the reinforcing rib 3. The top end face of the support leg 1 is fixedly connected to the bottom end face of the connector 7.

[0028] Specifically, before pouring concrete into the mold 506, grip the handle 603 to install the stress inducing block 601 inside the mounting groove on the bottom surface of the mold 506, and grip the handle 605 to insert the pin 604 into the through hole on the side of the mold 506 and the insertion hole on the side of the stress inducing block 601, thus completing the installation of the stress inducing block 601.

[0029] The portable self-vibrating and self-stirring concrete anti-cracking test mold 506, before pouring concrete into the interior of the mold 506, holds the handle 603, installs the stress inducing block 601 in the installation groove at the bottom end face of the mold 506, holds the handle 605, and inserts the pin column 604 into the through hole at the side of the mold 506 and the insertion hole 602 at the side of the stress inducing block 601, completes the installation of the stress inducing block 601, can flexibly replace and maintain the stress inducing block 601, and prolongs the service life of the stress inducing block 601.

[0030] Optionally, the inner wall of the installation groove is matched with the side of the stress inducing block 601, which ensures that the stress inducing block 601 can be stably installed in the mold 506 and will not be displaced or loosened during the test, thereby ensuring the accuracy and reliability of the test results. The through hole inner wall is matched with the side of the ejector rod 504, so that the ejector rod 504 can smoothly move in the through hole, facilitate the control of the demolding process of the concrete, make the demolding operation more simple and fast, and improve the test efficiency.

[0031] Optionally, as shown in Figure 2 The design of the non-slip pad 2 can significantly increase the friction between the support leg 1 and the ground, thereby preventing the equipment from sliding due to external force or uneven ground during use, which is particularly important for equipment that requires precise operation and stable environment.

[0032] Optionally, as shown in Figures 2-4 The reinforcing rib 3 serves as an additional support structure and can effectively increase the strength of the support leg 1, so that the overall mold 506 is more stable when subjected to external force or gravity, reducing the risk of deformation or damage.

[0033] Optionally, as shown in Figure 4 The rubber plate 509 has good elasticity and flexibility, so that the demolding process becomes easier after the concrete solidifies, reducing the damage to the concrete test piece during demolding.

[0034] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
