[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown:

[0024] Embodiment 1: The utility model provides a highway construction concrete compression detection device, comprising:

[0025] The compression testing mechanism 1 includes a testing platform assembly 11, a trapezoidal column 12 whose limit card is embedded in the testing platform assembly 11, a thickness adjustment assembly 13 whose limit sliding card is embedded in the testing platform assembly 11, and a hydraulic press assembly 14 installed on the testing platform assembly 11;

[0026] The demoulding mechanism 2 includes a first demoulding component 21 that is slidably embedded in the outer side of the bottom of the detection platform component 11, and a second demoulding component 22 that is slidably embedded in the detection platform component 11. The second demoulding component 22 moves downward to drive the first demoulding component 21 to move horizontally, and the horizontal movement of the first demoulding component 21 causes the trapezoidal column 12 to move upward;

[0027] The testing platform assembly 11 includes a testing platform body 111, a support arm 112 is fixedly connected to the upper side of the testing platform body 111, a threaded rod 113 is also fixedly connected to the outer side of the testing platform body 111, and a limit nut 114 is rotatably connected to the outer side of the threaded rod 113; the thickness adjustment assembly 13 includes a hollow mold frame 131, a sliding block 132 is fixedly connected to the outer side of the hollow mold frame 131, and a scale mark 133 is also fixedly connected to one side of the hollow mold frame 131; the hydraulic press assembly 14 includes a hydraulic press body 141 and a display screen 142;

[0028] The sliding block 132 is limited and slidably embedded in the outer side of the threaded rod 113 , the trapezoidal column 12 is limited and slidably embedded in the detection platform body 111 , the hollow mold frame 131 is limited and slidably embedded in the outer side of the trapezoidal column 12 , and the limiting nut 114 can support and limit the sliding block 132 .

[0029] Specifically, the hydraulic press body 141 and the display screen 142 are both fixedly mounted on the support arm 112 .

[0030] Specifically, the display screen 142 is electrically connected to the hydraulic press body 141 .

[0031] As can be seen from the above, when the hydraulic press body 141 is controlled to work, the pressure value can be read through the display screen 142;

[0032] The sliding block 132 is moved to drive the hollow mold frame 131 to move upward. After the hollow mold frame 131 moves upward, the depth of concrete that can be poured into the hollow mold frame 131 can be conveniently measured by the scale mark 133. When the sliding block 132 reaches a suitable position, the limit nut 114 is rotated to move along the threaded rod 113 and reach the upper and lower sides of the sliding block 132. The limit nut 114 can support the sliding block 132, so that the position of the hollow mold frame 131 is fixed;

[0033] During testing, after the configured concrete is poured into the hollow mold frame 131, the trapezoidal column 12 serves as the bottom support. After the concrete solidifies, the demoulding mechanism 2 drives the concrete and the hollow mold frame 131 to separate, and then the hollow mold frame 131 is retracted into the test bench body 111 through the limit nut 114; the hydraulic press body 141 is controlled to work to apply pressure to the concrete, and the reading displayed on the display screen 142 can measure the compressive strength of the concrete.

[0034] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that an L-shaped bracket 115 is fixedly connected to the bottom of the outer side of the detection table body 111; the first demolding component 21 includes a push plate 211, one side of the push plate 211 is fixedly connected to a guide rod 212, the outer side of the guide rod 212 is sleeved with a spring 213, and one side of the push plate 211 is also provided with a slope 214.

[0035] Specifically, the second demoulding assembly 22 includes a second push plate 221 , a second guide rod 222 is fixedly connected to the bottom of the second push plate 221 , and a second spring 223 is sleeved on the outer side of the second guide rod 222 .

[0036] Specifically, the push plate 211 is limited and slidably embedded in the detection platform body 111, the guide rod 212 is limited and slidably embedded in the L-shaped bracket 115, the spring 213 drives the guide rod 212 to move and makes the push plate 211 move to the outside of the detection platform body 111, the guide rod 222 is limited and slidably embedded in the L-shaped bracket 115, the spring 223 drives the push plate 221 to move upward and away from the L-shaped bracket 115, the push plate 221 moves downward and will abut against the slope 214 and push the push plate 211 to move horizontally, and the horizontal movement of the push plate 211 will drive the trapezoidal column 12 to move upward.

[0037] As can be seen from the above, stepping on the push plate 221 can make the bottom of the push plate 221 abut against the slope 214 and push the push plate 1 211 to move horizontally. The push plate 1 211 moves horizontally and abuts against the inclined surface on the lower side of the trapezoidal column 12, so that the trapezoidal column 12 moves upward. The upward movement of the trapezoidal column 12 pushes the concrete out of the hollow mold frame 131, thereby completing demoulding.

[0038] When the second push plate 221 moves downward, the second guide rod 222 moves on the L-shaped bracket 115 to play a guiding role and compress the second spring 223. After the second push plate 221 is no longer subjected to force, the second spring 223 returns to its original position and pushes up the second push plate 221 to separate from the first push plate 211.

[0039] When the push plate 211 moves laterally, the guide rod 212 moves on the L-shaped bracket 115 to play a guiding role and compress the spring 213. After the push plate 211 is no longer subjected to force, the spring 213 resets and pushes the push plate 211 to move in the opposite direction to separate from the trapezoidal column 12.

[0040] Embodiment 3: When it is necessary to test the compressive strength of newly poured concrete, place the testing device on a stable ground to ensure that all parts are stable and not loose. By adjusting the position of the sliding block 132 on the threaded rod 113 and fixing the limit nut 114, adjust the height of the hollow mold frame 131 according to the size of the concrete test block to be tested so that its internal space is suitable for pouring concrete. At the same time, observe the scale mark 133 to ensure that the concrete pouring depth meets the requirements, and evenly pour the configured concrete into the hollow mold frame 131 until it reaches the predetermined height. At this time, the trapezoidal column 12 serves as the bottom support to ensure that the concrete maintains a stable shape during the solidification process. After the concrete is completely solidified, it is ready for compressive strength testing. The demoulding mechanism 2 is started, and the construction personnel gently press the push plate 221 to move it downward and against the slope 214, thereby pushing the push plate 1 211 to move horizontally. The movement of the push plate 1 211 further drives the trapezoidal column 12 to move upward, and the concrete test block is ejected from the hollow mold frame 131, completing the demoulding process. At this time, the spring 223 and the spring 1 213 respectively play a reset role, so that the push plate 221 and the push plate 1 211 return to the initial position, and the demoulded concrete test block is placed on the test bench assembly 11 to ensure stability. Subsequently, the hydraulic press body 141 is started, and the pressure value is observed and recorded through the display screen 142. As the hydraulic press applies pressure to the concrete test block, the display screen 142 will display the pressure changes in real time until the test block is destroyed. At this time, the maximum pressure value displayed on the display screen is the compressive strength of the concrete. According to the pressure value recorded on the display screen 142, combined with the size and shape of the concrete test block, data analysis is performed to evaluate whether the compressive performance of the concrete meets the design requirements.
