Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] Referring to Figures 1-5 , the utility model provides an embodiment:

[0030] A kind of concrete compression resistance detection device for constructional engineering, including detection table 4, detection table 4 inside upper end is provided with protection mechanism 2, protection mechanism 2 includes protection frame 201, three air cylinders 202, two guide rods 203, two springs 204, fixed column 205, sliding block 206, clamping plate 207, screw rod 208, lead screw 209, gear 210 and rack 211, fixed column 205 upper and lower two are respectively fixedly arranged in the upper end of base 6 and the upper end in the inside of support frame 1, fixed column 205 one side lower end is fixedly arranged in the side of detection table 4, protection frame 201 one side is slidably arranged in the outside of fixed column 205, rack 211 rear end is fixedly arranged in the inside one side front end of protection frame 201, rack 211 outside is slidably arranged in the inside rear end of fixed column 205, gear 210 inside is fixedly arranged in the outside one side of lead screw 209, lead screw 209 outside is rotatably arranged in the inside upper end of detection table 4, rack 211 front end is engagedly connected in the outside of gear 210, sliding block 206 inside lower end is threadedly connected in the outside of lead screw 209, sliding block 206 inside upper end is threadedly connected in the outside of screw rod 208, clamping plate 207 one side is fixedly arranged in the one side of screw rod 208, two guide rods 203 upper end are all fixedly arranged in the upper end in the inside of support frame 1, protection frame 201 inside is slidably arranged in the outside of two guide rods 203, two springs 204 upper end are all fixedly arranged in the upper end in the inside of support frame 1, two springs 204 lower end are all fixedly arranged in the upper end of protection frame 201, clamping plate 207 one side is fixedly provided with non-slip mat 10, clamping plate 207 lower end is slidably arranged in the upper end of detection table 4, three pressure gauges 9 lower end are respectively fixedly arranged in the upper end of three air cylinders 202, and the output end of three air cylinders 202 is all fixedly provided with detection probe 13.

[0031] Specifically, in the process of carrying out the concrete compression detection, the concrete sample is first placed on the upper end of the detection table 4, then the cylinder 202 starts to fill with gas, and the operator controls the air intake of the three cylinders 202 in the support frame 1 through the adjusting valve 7 and the pressure gauge 9, so as to realize flexible switching of multiple compression detection modes. With the rise of the internal pressure of the cylinder 202, its output end slowly extends, so that the driving detection probe 13 approaches the concrete sample. The advancement of the output end of the cylinder 202 not only causes the detection probe 13 to move downward, but also drives the protective frame 201 to slide smoothly along the outside of the fixed column 205. During the sliding process of the protective frame 201, the spring 204 will be stretched by the movement of the protective frame 201 and gradually deformed. At the same time, the guide rod 203 ensures the linearity and stability of the protective frame 201 during sliding. When the detection is completed, the spring 204 can drive the protective frame 201 to reset. When the protective frame 201 slides to the preset position, the built-in rack 211 will precisely engage with the gear 210 inside the fixed column 205. The engagement of the gear 210 and the rack 211 will cause the gear 210 to rotate inside the fixed column 205, thereby driving the lead screw 209 to rotate synchronously inside the detection table 4. The rotation of the lead screw 209 will cause the sliding block 206 to move along the lead screw 209 to one side of the fixed plate 3. The sliding block 206 will also drive the screw rod 208 and the clamping plate 207 connected thereto to move synchronously. By first rotating the screw rod 208, the clamping plate 207 can automatically adapt to and clamp different sizes of concrete samples. When the protective frame 201 moves to the final position, it completely wraps the top area of the detection table 4, effectively preventing the splashing of debris caused by the compression damage of the concrete sample during the detection process, improving the safety of the detection. The protective frame 201 is made of transparent material, which facilitates the operator to watch the detection process. At the same time, the close cooperation between the clamping plate 207 and the fixed plate 3 completes the stable clamping of the concrete sample. At this time, the detection probe 13 will simultaneously apply different pressures to the concrete sample, realizing comprehensive and efficient detection of the compression resistance of the concrete. The non-slip mat 10 increases the friction between the clamping plate 207 and the concrete sample, preventing the sample from sliding during the detection process.

[0032] Referring to Figures 1-5 , a collection box 5 is slidably arranged on one side of the detection table 4, a base 6 is fixedly arranged at the lower end of the detection table 4, a support frame 1 is fixedly arranged at the upper end of the base 6, a filter screen 11 is fixedly arranged at the upper end of the detection table 4, a gas pump 12 is fixedly arranged at the upper end of the detection table 4, a fixed plate 3 is fixedly arranged at one side of the upper end of the detection table 4, a pneumatic cylinder seat 8 is fixedly arranged at the upper end of the inside of the support frame 1, three adjusting valves 7 are fixedly arranged at one side of the pneumatic cylinder seat 8, a pressure gauge 9 is fixedly arranged at the lower end of each adjusting valve 7, and the cylinder 202 is fixedly arranged at the upper end of the inside of the support frame 1.

[0033] Specifically, when the detection is completed, the air pump 12 is started, the debris scattered on the detection table 4 is sucked through the filter screen 11 and collected into the collection box 5 inside the detection table 4. Not only the detection environment is kept clean and sanitary, but also the subsequent detection work is facilitated, the cleaning frequency of the inside of the device is reduced, the maintenance cost and downtime are reduced, the pressure gauge 9 can reflect the pressure value applied by the detection probe 13 at the output end of the air cylinder 202 in real time, the adjusting valve 7 is used to adjust the working pressure of the air cylinder 202, so that the device realizes diversified compression resistance detection effect in a single test, and the support frame 1 and the base 6 play a supporting role, improving the stability of the device.

[0034] Working principle: when the concrete in the construction engineering is detected, the concrete is placed on the upper end of the detection table 4, then the air is introduced into the cylinder seat inside the air cylinder 202, then the adjusting valve 7 and the pressure gauge 9 are adjusted, so that the three air cylinders 202 are synchronized, the effect of multiple compression resistance detection is realized, at this time the output end of the air cylinder 202 is extended and drives the detection probe 13 to move downward, the movement of the output end of the air cylinder 202 will push the protective frame 201 to move downward outside the fixed column 205, the downward movement of the protective frame 201 will make the spring 204 connected with it be pulled and gradually deformed, when the protective frame 201 slides, the guide rod 203 will play a guiding role, when the protective frame 201 slides to the set position, the rack 211 inside it will engage with the gear 210 inside the fixed column 205, thereby causing the gear 210 to rotate inside the fixed column 205, the rotation of the gear 210 will promote the synchronous rotation of the lead screw 209 inside the detection table 4, since the sliding block 206 is screwed with the lead screw 209, when the lead screw 209 rotates, it will make the sliding block 206 move towards the fixed plate 3, the movement of the sliding block 206 will drive the screw rod 208 and the clamping plate 207 to move synchronously, the clamping plate 207 can adapt to the synchronous size of the concrete by rotating the screw rod 208, when the protective frame 201 moves to the final position, it will wrap the upper end of the detection table 4, which can effectively prevent the splashing of debris caused by the destruction of the concrete test piece, and the clamping plate 207 and the fixed plate 3 will complete the automatic clamping of the concrete, at the same time, the three detection probes 13 will detect the concrete with different force, improving the detection efficiency.

[0035] Secondly, when the detection is completed, the air pump 12 inside the detection table 4 will be activated, so that the debris on the filter screen 11 is sucked into the collection box 5 inside the detection table 4, thereby keeping the detection environment clean.
