Description

Technical Field

[0001] This utility model relates to the field of mortar testing machinery technology, and in particular to a penetration-type concrete mortar strength tester. Background Technology

[0002] The penetration test is a novel on-site testing method that utilizes the correlation between the concentration of the mortar penetration point and the mortar's compressive strength. It employs a compression spring to apply load, driving a mortar penetration point into the mortar. The mortar's compressive strength is then calculated from the penetration depth using a strength curve. This method is highly praised by users for its advantages such as simple operation, accurate test results, and low testing costs. It is also currently the most widely used testing technology for on-site mortar strength testing.

[0003] Chinese Patent No. CN220473252U discloses a penetration-type concrete mortar strength tester, including a body. A conical nail is movably mounted on the lower end of the body. Supports are evenly distributed on the outer wall of the body. A horizontal bar is fixedly mounted on the end of each support away from the body. An extension rod is movably sleeved on the inner wall of the horizontal bar. A vertical rod is fixedly mounted on the lower end face of the extension rod away from the horizontal bar. This invention, through the cooperation of the conical nail, suction cup, vertical rod, and support, and utilizing the suction cup, achieves the fixation of the concrete mortar tester, effectively solving the problem of positional displacement of the concrete mortar tester. The suction cup adsorption method strengthens the stability of the concrete mortar tester during testing, preventing tilting of the tester due to muscle fatigue of the operator. By strengthening the stability of the concrete mortar tester, the accuracy of mortar test data is improved.

[0004] Existing penetration-type concrete mortar strength testers, due to their large impact force, cause mortar fragments to splatter when the test pins penetrate the cement mortar, potentially injuring test personnel and posing a safety hazard. Furthermore, the external parts of the machine are connected by connecting components and suction cups, making the suction cups and other components fixed to the machine body. This limits the range of application of the fixed components to the machine body and increases the cost of the machine body's connection structure. Utility Model Content

[0030] Example 1

[0031] like Figure 1 - Figure 4As shown, the present invention proposes a penetration-type concrete mortar strength tester, comprising: a base assembly, a body 2, an adjustment assembly, and a splash-proof assembly; the base assembly includes a base plate 1, a vertical plate 101, an opening 102, a fixing block 103, an adjustment rod 104, and a positioning clamp 105; the base plate 1 is connected to both sides of the vertical plate 1, and the two vertical plates 101 are respectively provided with openings 102 and connected to fixing blocks 103, the fixing blocks 103 and the adjustment rods 104 are connected one-to-one, and the adjustment rods 104 are respectively connected to the positioning clamps 105; the body 2 is connected to the base plate 1; the adjustment assembly is connected to the outside of the vertical plate 101; the splash-proof assembly is connected to the adjustment assembly; the splash-proof assembly includes a fixing plate 4, a glass baffle 401, a splicing rod 402, and a connecting block 403; the fixing plate 4 is connected to the outside of the glass baffle 401, the glass baffle 401 is connected to both sides of the glass baffle 401, and the splicing rods 402 are respectively connected to the connecting blocks 403. The glass baffle 401 is made of impact-resistant glass, such as ceramic composite glass, which improves the durability of the glass baffle 401, facilitates the use of the machine body 2 and the staff, and facilitates the reduction of safety hazards.

[0032] To further explain, one end of the adjusting rod 104 passes through the opening 102 and connects to the positioning clamp 105. The fixing block 103 is provided with a reserved mounting hole, and the adjusting rod 104 is provided with four reserved connection holes. The positioning clamp 105 is connected to the outside of the machine body 2, and a rubber soft layer is provided on the connecting end face of the positioning clamp 105 and the machine body 2. The connecting block 403 is connected to one side of the mounting rod 3 and is detachably connected. The rubber soft layer facilitates the protection of the end face of the positioning clamp 105 and the outer wall of the machine body 2, preventing damage to the machine body 2 caused by clamping and fixing the machine body 2.

[0033] Example 2

[0034] like Figure 1 and Figure 3 As shown, this utility model proposes a penetration-type concrete mortar strength tester. Based on the above embodiments, this embodiment also details the specific components of the machine body 2 and the adjustment assembly, as well as their coordination method.

[0035] To further explain, a conical nail 201 is movably connected to the lower end of the body 2, and a column is connected to the upper part of the body 2. Hand grips 202 are connected to both sides of the column. The machine body 2 is equipped with a movable rod, a fixed rod, a ball nut, a ball screw, and a micro motor. The upper end of the cone nail 201 is connected to the movable rod, and the fixed rod located inside the machine body 2 is movably sleeved on the outer wall of the movable rod. The outer wall of the movable rod is connected to the ball nut, and the inner wall of the ball nut is threaded with the ball screw. The upper end of the ball screw is connected to the output shaft of the reducer of the micro motor. The machine body 2 is equipped with a display screen. When the strength tester is in use, the power of the micro motor is turned on. After the micro motor is turned on, the ball screw rotates. The ball screw rotates in a circular motion and drives the ball nut to move vertically. The movement of the ball nut drives the movable rod, and the movable rod drives the cone nail 201 to move into the mortar. Finally, the mortar strength test data is observed through the display screen. The model of the micro motor is DC4GN40-12-1800 / 4GN3K micro DC motor, and the model of the machine body 2 is SJY-800B penetration mortar strength tester.

[0036] Further explanation: The adjustment assembly includes a mounting rod 3, an extension rod 301, a bracket 302, and two sets of fasteners. The mounting rod 3 is hollow inside, with an open end on one side connecting to the extension rod 301. The extension rod 301 connects to the bracket 302. The mounting rod 3 has multiple pre-drilled holes, and the extension rod 301 has a pre-drilled threaded hole. Flange bolts are threaded through and connected to the pre-drilled holes to connect the extension rod 301 and the mounting rod 3. By adjusting the connection position of the pre-drilled threaded hole and any one of the pre-drilled holes, the usable length of the extension rod 301 and the mounting rod 3 can be adjusted. The extension rod 301 is connected to the bracket 302 and the two sets of fasteners, thereby adjusting the applicable positions of the two sets of fasteners.

[0037] To further explain, the two sets of fasteners include a mounting post 303, a connecting post 304, and a suction cup 305, respectively; the mounting post 303 is connected to one side of the bracket 302, the mounting post 303 and the connecting post 304 are threaded together, and one end of the connecting post 304 is connected to the suction cup 305. The connecting column 304 and mounting column 303 are connected separately. The connecting column 304 drives the suction cup 305 to connect to the adjustment component. The suction cup 305 reinforces the stability of the machine body 2 during testing, preventing tilting of the concrete mortar strength tester due to muscle fatigue of the operator. This improves the accuracy of the penetration-type concrete mortar strength tester. Before each use, check the surface of the suction cup 305 for cracks or deformation, clean the adsorption and contact surfaces, and keep it dry. When adsorbing, try to completely expel the internal air (e.g., press the edge of the suction cup 305 until there are no air bubbles). Avoid long-term use on high temperature, oily, or rough surfaces. The silicone suction cup 305 is generally more resistant to aging than ordinary rubber and is suitable for long-term use. The metal-reinforced suction cup 305 has a more stable structure and can reduce component damage. If the adsorption force is significantly reduced or the material is aged, disassemble and replace the suction cup 305 in time to avoid safety risks.

[0038] The working principle of this utility model is as follows: When the concrete mortar strength tester body 2 is in use, it is connected to the fixed plate 4 and the glass baffle 401. The two sides of the glass baffle 401 are connected to the splicing rod 402. The splicing rod 402 is connected to the mounting rod 3 through the connecting block 403. The connecting block 403 and the mounting rod 3 are detachably connected by flange screws. When the operator operates the concrete mortar strength tester body 2 connected to the base plate 1, the conical nail 201 of the body 2 passes through the circular hole. Then, the positioning clamp 105 is adjusted to the appropriate matching position according to the body 2. The positioning clamp 105 is adjusted to the outer wall of the body 2. The positioning clamp 105 is installed through the adjusting rod 104. The reserved connection hole corresponding to 104 corresponds to the reserved installation hole of the fixing block 103. Flange bolts and nuts are used to connect the adjusting rod 104 and the fixing block 103. The positioning clamp 105 is positioned and connected to the outside of the machine body 2 for positioning and clamping the machine body 2. The vertical plate 101 is connected to the mounting rod 3. The mounting rod 3 is connected to the bracket 302 through the extension rod 301. The bracket 302 is threadedly connected to the mounting column 303 and the connecting column 304. The connecting column 304 drives the suction cup 305. The suction cup 305 is fixed on the block and plays a fixing role, which facilitates the use of the concrete mortar strength tester machine body 2 for testing the concrete mortar strength of the block.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
