Description

Technical Field

[0001] This utility model relates to the field of concrete strength testing technology, specifically a concrete strength testing device for road construction. Background Technology

[0002] Modern roads are generally constructed using concrete as the primary material, making it one of the most important civil engineering materials. Concrete is characterized by abundant raw materials, low price, and simple production processes. It also boasts high compressive strength, good durability, and a wide range of strength grades. Road construction requires a large quantity of concrete. Before use, its strength needs to be tested using a strength testing device to ensure proper application.

[0003] However, currently, when concrete is being tested for strength, it will crack when it cannot withstand the pressure, which poses a danger to workers as there is no way to protect it. Moreover, cleaning up the cracked concrete is very inconvenient, which affects the progress of subsequent testing. Therefore, this does not meet the existing needs. To address this, we have proposed a concrete strength testing device for road construction. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete strength testing device for road construction, in order to solve the problems mentioned in the background art, such as the concrete cracking when it cannot withstand the pressure during strength testing, which makes it difficult to protect workers and poses a danger. Moreover, the cracked concrete is very inconvenient to clean up, thus affecting the subsequent testing progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete strength testing device for road construction, comprising a base plate, an L-shaped plate installed behind the upper surface of the base plate, a motor installed on the upper surface of the L-shaped plate, a rotating plate rotatably arranged below the motor, a hydraulic rod installed in the middle of the lower surface of the rotating plate, a pressure sensor installed on the lower surface of the hydraulic rod, a detection pressure plate installed on the lower surface of the pressure sensor, and first electric push rods arranged on both sides of the hydraulic rod, the lower surface of the first electric push rods being fixed. A lifting plate is fixedly connected, and a circular groove is provided on the lower end face of the lifting plate. An installation plate is movably installed on one side of the inner side of the circular groove via a second electric push rod. A connecting plate is movably provided on the lower end face of the installation plate. Multiple sets of bristles are evenly arranged on the lower end face of the connecting plate. A detection seat is installed in the middle of the upper end face of the base plate. A detection groove is provided on the upper end face of the detection seat. A horizontal groove is provided below the front end face of the detection seat. A drawer is provided inside the horizontal groove. An air pump is installed on the bottom surface of the drawer. A filter screen is provided above the air pump.

[0006] Preferably, the output end of the motor is fixedly connected to the upper end face of the rotating plate via a coupling, and the hydraulic rod passes through the lifting plate.

[0007] Preferably, the first electric push rod is fixedly connected to the rotating plate via a groove, the upper end face of the second electric push rod is fixedly connected to the inner wall of the circular groove, and the lower end face of the second electric push rod is fixedly connected to the mounting plate via screws.

[0008] Preferably, the filter screen is fixedly connected to the inner wall of the drawer via a slot, and the horizontal groove is connected to the detection groove via multiple connecting grooves.

[0009] Preferably, the output end of the air pump is connected to a retractable hose, the rear end face of the detection seat is provided with a through hole, the other end of the retractable hose extends to the outside of the detection seat, and the retractable hose is fixedly connected to the through hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up a detection groove, a detection seat, and a lifting plate, allows the entire detection process to take place within the detection groove. The lifting plate can extend into the inner side of the detection groove to seal it, preventing fragments from splashing out when the concrete cracks under pressure. Furthermore, by incorporating a vacuum pump, a drawer, and a filter screen, when the concrete cracks, fragments are sucked into the top of the filter screen through a connecting groove. A motor, a connecting plate, and brush bristles control a hydraulic rod to raise the detection pressure plate. Then, by controlling a second electric push rod, the connecting plate and brush bristles move downwards. Turning on the motor causes the rotating plate to rotate, which in turn causes the connecting plate and brush bristles to rotate around the center of the detection groove. The brush bristles further clean any remaining powder and debris, which are ultimately collected above the filter screen. The drawer can be pulled out using a handle for cleaning. This utility model avoids concrete debris splashing, ensuring the safety of workers and facilitating the collection and cleaning of cracked concrete debris. Attached Figure Description

[0022] The output end of motor 3 is fixedly connected to the upper end face of rotating plate 4 through a coupling. Hydraulic rod 19 passes through lifting plate 5. When motor 3 is working, it can drive rotating plate 4 to rotate.

[0023] The first electric push rod 9 is fixedly connected to the rotating plate 4 through a groove. The upper end face of the second electric push rod 18 is fixedly connected to the inner wall of the circular groove 15, and the lower end face of the second electric push rod 18 is fixedly connected to the mounting plate 12 through screws, thereby improving the stability of the installation of the first electric push rod 9 and the second electric push rod 18.

[0024] The filter screen 13 is fixedly connected to the inner wall of the drawer 8 through a slot, and the horizontal groove 7 is connected to the detection groove 20 through multiple connecting grooves to improve the stability of the connection between the filter screen 13 and the drawer 8.
