[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Figures 1-4 As shown, the technical solution adopted by the present invention is as follows: the construction concrete quality detection device includes a workbench 1, and a protective frame 8 is fixedly installed on the upper end surface of the workbench 1.

[0028] Limiting plates 5 are slidably mounted on both sides of the interior of the protection frame 8 .

[0029] Specifically, second sliders 16 are fixedly connected to the upper and lower ends of both sides of the limit plate 5. Second sliding grooves 17 are defined on both sides of the inner wall of the protective frame 8 at positions corresponding to the second sliders 16. The second sliders 16 are slidably mounted within the corresponding second sliding grooves 17. A second spring 18 is fixedly connected to the inner wall of the second sliding groove 17, and the other end of the second spring 18 is fixedly connected to the second slider 16.

[0030] Fixed columns 6 are fixedly connected to both sides of the upper end surface of the limiting plate 5 .

[0031] Sliding plates 7 are movably provided on both sides of the upper end surface of the workbench 1 .

[0032] Inclined blocks 4 are mounted on both sides of the upper end surface of the sliding plate 7 at positions corresponding to the fixed columns 6 for limited sliding.

[0033] Specifically, the upper end surface of each sliding plate 7 is provided with a first sliding groove 14, within which a first slider 13 is slidably mounted, the top end of each first slider 13 being fixedly connected to the corresponding inclined surface block 4. A first spring 15 is fixedly connected to the inner wall of the first sliding groove 14, the other end of which is fixedly connected to the first slider 13.

[0034] The inclined surface block 4 is slidably matched with the corresponding fixed column 6 .

[0035] Detection heads 12 are fixedly mounted on opposite surfaces of the two sliding plates 7 , and through holes are provided on the side walls of the protection frame 8 at positions corresponding to the detection heads 12 .

[0036] Fixed plates 3 are fixedly installed on both sides of the upper end surface of the workbench 1, and telescopic rods 2 are fixedly installed on the fixed plates 3. The telescopic ends of the telescopic rods 2 are fixedly connected to the corresponding sliding plates 7.

[0037] To clean the top surface of the support base plate 9, a material discharge port is provided on the upper end surface of the workbench 1 at a position corresponding to the protective frame 8. A chute is provided in the discharge port, and the support base plate 9 is slidably installed in the chute. A buckle slot 10 is provided on one side of the support base plate 9. A collection box 11 is movably placed at the position corresponding to the support base plate 9 below the workbench 1.

[0038] Working principle:

[0039] First, place the concrete block at the center of the rectangular protection frame 8 and ensure that the concrete block is aligned with the two detection heads 12 .

[0040] Then, the two telescopic rods 2 are activated, pushing the two sliding plates 7 toward each other, thereby driving the inclined surface block 4 to move, so that the inclined surface of the inclined surface block 4 contacts the fixed column 6. Since the elastic coefficient of the first spring 15 is relatively high, as the inclined surface block 4 moves, it pushes the fixed column 6 toward the concrete block, while the inclined surface block 4 does not slide on the sliding plates 7.

[0041] The limiting plate 5 is driven by the fixing column 6 to move toward the concrete block, and at the same time, the second spring 18 contracts, and the second slider 16 slides in the second slide groove 17. As a result, the concrete block is clamped by the two limiting plates 5, preventing the concrete block from being displaced during the detection process, thereby affecting the detection effect.

[0042] As the sliding plate 7 continues to move, the detection head 12 will pass through the through hole on the protective frame 8 and contact the concrete block. During this process, since the limit plate 5 has abutted against the concrete block, the fixed column 6 is limited, so that the inclined block 4 no longer pushes the fixed column 6 to move, and slides on the sliding plate 7.

[0043] The two inclined blocks 4 on the same sliding plate 7 move away from each other, and at the same time drive the corresponding first springs 15 to contract. During this process, the limit plate 5 does not move, and the detection of the concrete block is finally completed.

[0044] After the detection is completed, the telescopic rod 2 is started to drive the sliding plate 7 back to the initial position. During this process, the inclined block 4 will return to the initial position under the reset action of the first spring 15, and then the limit plate 5 will return to the initial position under the reset action of the second spring 18.

[0045] By pulling the buckle slot 10, the support base plate 9 is pulled out. During the process of pulling out the support base plate 9, the broken concrete blocks on the support base plate 9 will fall into the collection box 11 under the obstruction of the limit plate 5, thereby completing the cleaning of the top surface of the support base plate 9 and preventing the broken concrete blocks from affecting the next inspection.

[0046] Example 2: Figure 5-Figure 6 As shown, the difference between this embodiment and Example 1 is that third chutes 22 are provided on both sides of the upper end surface of the workbench 1, and third sliders 23 are fixedly mounted on the bottom side of the sliding plate 7. The third sliders 23 are slidably mounted within the corresponding third chutes 22. A screw rod 21 is rotatably mounted within one of the third chutes 22, and a guide rod 20 is fixedly mounted within the other third chutes 22. The screw rod 21 and the corresponding third slider 23 are both threadedly connected, and the guide rod 20 and the corresponding third slider 23 are both slidably connected. A motor 19 is fixedly mounted on the side wall of the workbench 1, and the output shaft of the motor 19 is fixedly connected to one end of the screw rod 21.

[0047] The threads on both sides of the screw rod 21 rotate in opposite directions, so that when the screw rod 21 rotates, the two third sliding blocks 23 are driven to move closer to or away from each other.

[0048] Working principle: Compared with embodiment 1, the movement of the sliding plate 7 is achieved by starting the motor 19.

[0049] Specifically, forward rotation of the output shaft of motor 19 drives screw 21, which in turn drives third slider 23 to slide within corresponding third slot 22, thereby moving the two sliding plates 7 closer together. Reverse rotation of the output shaft of motor 19 drives the two sliding plates 7 away from each other. The movement of the remaining components is the same as in Example 1.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
