[0034] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by identical or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0035] The present invention provides a road construction quality detection device, see Figure 1 and Figure 2 The highway construction quality inspection device includes: a detection seat 1, a placement seat 2, a pressure driving mechanism 3 and a baffle assembly 4; wherein the placement seat 2 is arranged above the detection seat 1, and the placement seat 2 is provided with a placement groove 201, and the placement groove 201 is used to place the concrete block to be inspected; a support rod 12 is symmetrically provided on the opposite sides of the detection seat 1, and the pressure driving mechanism 3 is connected to the two support rods 12, and the pressure driving mechanism 3 is located directly above the placement seat 2; a detection pressure seat 32 is fixedly provided at the telescopic end of the pressure driving mechanism 3, and a pressure sensor is provided in the detection pressure seat 32, and the detection pressure seat 32 is used to apply pressure to the concrete block; multiple baffle assemblies 4 are arranged around the placement seat 2, and multiple baffle assemblies 4 are located between the placement seat 2 and the pressure driving mechanism 3.

[0036] When pressure testing concrete blocks during highway construction, the concrete block to be tested is placed in the placement groove 201 in the placement seat 2, and then the telescopic end of the pressure driving mechanism 3 is controlled to move, which drives the testing pressure seat 32 to move downward. After that, the testing pressure seat 32 will contact the concrete block in the placement groove 201 and gradually squeeze it. When the testing pressure seat 32 applies the ultimate pressure to the concrete block, the concrete block will break. At this time, the test is stopped, and the pressure sensor in the testing pressure seat 32 can detect the ultimate pressure that the concrete block can withstand. The baffle assembly 4 can block the fragments generated during the test process. On the one hand, it not only prevents the fragments from splashing near the workers and causing serious injuries to the workers, but also prevents the fragments from falling around the testing seat 1 and being difficult to clean, thereby improving safety for highway construction.

[0037] See also Figure 1 Each baffle assembly 4 is provided with a set of limiting brackets 43, and the baffle assembly 4 is connected to the detection seat 1 via the limiting brackets 43. In this embodiment, the detection seat 1 and the placement seat 2 are both rectangular in shape, and four sets of baffle assemblies 4 are provided. The four sets of baffle assemblies 4 are respectively arranged at the four side positions of the rectangular placement seat 2; each set of limiting members includes two L-shaped limiting rods, one end of which is connected to the limiting assembly, and the other end is fixedly connected to the top surface of the detection seat 1.

[0038] In this embodiment, the pressure drive mechanism 3 includes a cylinder seat 31 and a cylinder, the cylinder seat 31 is fixedly connected to the two support rods 12, the cylinder barrel of the cylinder is fixedly connected to the cylinder seat 31, and the detection pressure seat 32 is fixedly connected to the front end of the telescopic rod of the cylinder. In this embodiment, the support rods 12 are L-shaped support rods, the cylinder seat 31 is connected to the upper ends of the two support rods 12, and the lower ends of the two support rods 12 are fixedly connected to the detection seat 1, and the support rods 12 play a supporting and fixing role for the cylinder seat 31. In another alternative embodiment, the pressure drive mechanism 3 includes an oil cylinder seat and a hydraulic cylinder, the oil cylinder seat is fixedly connected to the two support rods 12, the cylinder barrel of the hydraulic cylinder is fixedly connected to the oil cylinder seat, and the detection pressure seat 32 is fixedly connected to the front end of the telescopic rod of the hydraulic cylinder.

[0039] Furthermore, a plurality of support shafts 11 are vertically fixed on the top of the detection seat 1, and the placement seat 2 is slidably connected to the plurality of support shafts 11. Figure 3, two L-shaped vertical rods 51 are symmetrically provided on both sides of the telescopic end of the pressure drive mechanism 3, and a first rack 52 is provided at the lower end of each of the two L-shaped vertical rods 51. A second rack 53 is provided on each side of the placement seat 2. A central gear 54 is rotatably provided on both sides of the detection seat 1. The first rack 52 and the second rack 53 are respectively provided on both sides of the central gear 54, and the first rack 52 and the second rack 53 are both engaged with the central gear 54 for transmission. In this embodiment, four support shafts 11 are provided on the top of the detection seat 1, and four guide holes are provided on the placement seat 2. The placement seat 2 is slidably connected to the support shaft 11 through the guide holes. A groove is provided in the middle of the detection seat 1, and the lower ends of the first rack 52 and the second rack 53 extend into the groove. A gear shaft 55 is laterally provided on the top of the detection seat 1, and the central gear 54 is rotatably provided in the middle of the gear shaft 55, and the central gear 54 is located above the groove. When the detection device is in operation, when the telescopic end of the pressure drive mechanism 3 moves downward, the telescopic end simultaneously drives the two L-shaped vertical rods 51 to move, and the L-shaped vertical rod 51 drives the first rack 52 at the lower end to move downward. The first rack 52 drives the second rack 53 upward through the central gear 54, causing the two second racks 53 to push the placement seat 2 upward. At this time, the placement seat 2 and the detection pressure seat 32 will move synchronously, reducing the movement distance of the detection pressure seat 32, improving the detection rate of the concrete block, and facilitating the detection pressure seat 32 to continuously squeeze the concrete block. An elastic telescopic frame 56 can also be installed at the bottom of the first rack 52 and the second rack 53. The upper end surface of the elastic telescopic frame 56 is provided with a groove that is compatible with the first rack 52 and the second rack 53. The bottom end of the elastic telescopic frame 56 is connected to the detection seat 1. When in operation, the elastic telescopic frame 56 is provided at the bottom of the first rack 52 and the second rack 53 to provide a certain amount of movement margin for the first rack 52 and the second rack 53, so that the first rack 52 can indirectly drive the second rack 53 to move.

[0040] Furthermore, the baffle assembly 4 includes a fixed baffle 41 and a movable baffle 42. A rectangular groove 411 is symmetrically formed at the upper and lower ends of the fixed baffle 41. A movable baffle 42 is slidably connected to each rectangular groove 411. An elastic expansion member is provided between the movable baffle 42 and the fixed baffle 41. Figures 4 to 6, sliding grooves 412 are symmetrically provided on the two side walls in the length direction of the rectangular groove 411, and limiting plates 421 are symmetrically provided on both sides in the length direction of the movable baffle 42, and the limiting plates 421 are slidably connected to the corresponding sliding grooves 412; the elastic telescopic part includes an elastic telescopic rod 44 and a cylindrical helical compression spring 45, one end of the elastic telescopic rod 44 is fixedly connected to the inner wall of the sliding groove 412 close to the bottom wall of the rectangular groove 411, and the other end of the elastic telescopic rod 44 is fixedly connected to the limiting plate 421, and the cylindrical helical compression spring 45 is sleeved on the outside of the elastic telescopic rod 44, and the two ends of the cylindrical helical compression spring 45 respectively abut against the inner wall of the sliding groove 412 and the limiting plate 421. During operation, the L-shaped vertical rod 51 and the placement seat 2 move toward the baffle assembly 4 from the upper and lower sides respectively. When the movable baffle 42 is pressurized, the movable baffle 42 will simultaneously drive the limit plate 421 to move, and the limit plate 421 compresses the elastic telescopic rod 44 and the cylindrical helical compression spring 45. At this time, the movable baffle 42 can be conveniently moved inside the rectangular groove 411 of the fixed baffle 41, and the elastic telescopic rod 44 and the cylindrical helical compression spring 45 give the movable baffle 42 a certain amount of movement margin, which is convenient for the movable baffle 42 and the fixed baffle 41 to continue to cover the surroundings of the placement seat 2. When one inspection is completed, a gap is left between the movable baffle 42 and the placement seat 2, which is convenient for taking out and putting in concrete blocks.

[0041] Furthermore, if Figure 7 As shown, a limiting shaft 21 is fixedly connected to one side of the placement slot 201, and a receiving plate 22 is rotatably connected to the limiting shaft 21. The shape of the receiving plate 22 is adapted to the shape of the placement slot 201. The receiving plate 22 is used to place the concrete blocks to be tested, and a fragment release port is provided at the bottom of the placement slot 201. The provision of the receiving plate 22 facilitates the placement of concrete blocks and facilitates the removal of fragments after testing. Preferably, in this embodiment, a torsion spring is provided between the receiving plate 22 and the limiting shaft 21; see Figure 8The placement seat 2 is provided with an electric push rod 23, which is located on the side of the placement seat 2 away from the limiting axis 21. The telescopic rod of the electric push rod 23 extends through the placement seat 2 into the placement slot 201. A clamping rod 24 is provided at the front end of the telescopic rod of the electric push rod 23. A clamping seat 25 is provided on the end of the receiving plate 22 away from the limiting axis 21, and the clamping rod 24 is clamped into the clamping seat 25. In the initial state, the receiving plate 22 is tilted under the action of the torsion spring. When the concrete block needs to be inspected, the receiving plate 22 is rotated to a horizontal state, and the electric push rod 23 pushes the clamping rod 24 to move, causing the clamping rod 24 to clamp into the clamping seat 25, thereby fixing the receiving plate 22. After the concrete block inspection is completed, there are detected concrete fragments on the surface of the receiving plate 22. The electric push rod 23 is used to pull the clamping rod 24 outward to disengage the clamping rod 24 from the clamping seat 25. Under the action of the torsion spring, the receiving plate 22 can be restored to the inclined state, and the fragments can slide out along the inclined receiving plate 22 and fall from the fragment release port at the bottom of the placement groove 201.

[0042] Furthermore, the detection seat 1 is also provided with a recovery inclined plate 6, see Figure 9 The recovery ramp 6 is located below the debris release opening at the bottom of the storage tank 201. By providing the recovery ramp 6, after the inspection is completed, the debris slides off the receiving plate 22 and falls from the debris release opening at the bottom of the storage tank 201 onto the recovery ramp 6. A storage box can be placed at the bottom of the recovery ramp 6 to collect the debris, making it easier to clean the debris.

[0043] In summary, the highway construction quality inspection device provided by the present invention, by arranging baffle assemblies around the placement seat, can effectively shield debris generated during the inspection process when the concrete block placed on the placement seat is inspected by the inspection pressure seat, preventing the debris from splashing onto workers and falling around the inspection seat. This highway construction quality inspection device ensures safety during concrete block inspection and improves the convenience of debris removal after inspection.
