Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete pressure testing, and in particular to an asphalt concrete pressure testing device. Background Technology

[0002] Concrete is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water in a certain proportion. It is widely used in civil engineering. Concrete is characterized by abundant and inexpensive raw materials and a simple production process, leading to its increasing use. Concrete also has characteristics such as high compressive strength, good durability, and a wide range of strength grades. These characteristics make its applications very broad, not only in various civil engineering projects, but also in shipbuilding, machinery manufacturing, marine development, geothermal engineering, and other fields. Concrete is also an important material, and during production, it is subject to random sampling to test its strength.

[0003] The published patent with authorization announcement number CN221667425U describes a method for placing concrete blocks inside a placement box for pressure testing. The box is supported around its bottom by pads, and a scraper is slidably connected to a slide rail via a slider. Upon completion of the pressure test, pulling the handle causes the scraper to slide along the inner wall of the placement box, scraping out the concrete block or crushed fragments through the slots. During the pressure test, any substandard concrete blocks can be cleaned up during crushing, preventing fragments from remaining inside the testing box and facilitating reuse.

[0004] Although the aforementioned patent document describes how a scraper cleans up the crushed fragments, it cannot completely remove small fragments or particles during the cleaning process. A small brush is still needed for further cleaning, which makes it impossible to guarantee the accuracy of subsequent strength testing. Utility Model Content

[0026] This embodiment provides an asphalt concrete pressure testing device, including a plate 1, an auxiliary mechanism 6, and a cleaning block 3. A handrail 5 is provided on the upper part of the plate 1, and through holes 501 are provided on both sides of the handrail 5. Semi-through grooves 4 are also provided on both sides of the plate 1, and movable chambers 102 are provided within the semi-through grooves 4. The auxiliary mechanism 6 is located on both sides of the handrail 5, and includes a rocker arm 601 and a push rod 602. The middle part of the rocker arm 601 is movably connected to the middle part of the through holes 501 via a rotating shaft. The push rod 602 is located within the plate 1. Figure 3 As shown in the diagram, one end of the push rod 602 is located below the rocker 601, and the other end of the push rod 602 is installed inside the movable cavity 102. The push rod 602 can move up and down within the movable cavity 102. The cleaning block 3 is disposed on one side of the plate 1, and the cleaning block 3 is fixedly connected to the push rod 602. The push rod 602 drives the cleaning block 3 to move up and down. In use, by holding the armrest 5 and one end of the rocker 601 inside the armrest 5, the rocker 601 is moved. The other end is pressed down, thus pressing against the roller 603 at the upper end of the push rod 602. The push rod 602 moves down, thereby driving the cleaning block 3 to move down, which in turn squeezes the brush at the bottom of the cleaning block 3 and pulls the plate body 1 to better clean the broken particles. It should be noted that a spring can be set on the outer periphery of the upper end of the push rod 602. The spring keeps the push rod 602 in an upward force. After cleaning is completed, the plate body 1 returns to its original position, the handle 5 is released, and the cleaning block 3 moves up under the action of the spring. It only moves down under force when in use.

[0027] It should be further explained that one end of the rocker 601 is located inside the handrail 5, and the other end is located outside the handrail 5. A roller 603 is provided between the rocker 601 and the push rod 602. The roller 603 is connected to the push rod 602. By pressing down on the roller 603, the roller 603 is rolled under force, thereby causing the push rod 602 to move downward.

[0028] It needs to be further explained that, such as Figure 3 As shown, a movable groove 103 communicating with the movable cavity 102 is provided on one side of the plate 1. A connecting block 7 is provided in the movable groove 103. The connecting block 7 is fixedly connected to the cleaning block 3 and the push plate.

[0029] It should be further explained that the cross-section of the cleaning block 3 is triangular, and the inclined surface of the triangle faces the direction of opening and closing the door. At the same time, during the pressure test, the inclined surface avoids concrete splashing. The lower part of the cleaning block 3 is provided with bristles 8. When the bristles 8 are pressed down, the cleaning effect is better when the plate 1 is pulled.

[0030] It should be further explained that sliders 101 are provided on both sides of the plate 1. Each slider 101 has an inclined surface facing the plate. The inclined surface is designed to push out debris in the groove when the plate moves, making it easy to clean.

[0031] It should be further noted that the upper end of the push rod 602 is provided with a groove, and the roller 603 is installed in the groove.

[0032] Working principle of this utility model:

[0033] In use, a cleaning block 3 that can move up and down is provided on the cleaning surface of the plate 1, and the degree of pressure can be controlled by the handle 5. When in use, by holding the handle 5 and one end of the rocker 601 inside the handle 5, the other end of the rocker 601 is pressed down, thereby pressing against the roller 603 at the upper end of the push rod 602. The push rod 602 moves down, thereby driving the cleaning block 3 to move down, thereby squeezing the brush at the bottom of the cleaning block 3 and pulling the plate 1, so as to better clean the broken particles. It is convenient to use, avoids secondary cleaning by the operator, and improves cleaning efficiency.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
