Technical Field

[0001] The utility model relates to the field of road construction detection, and more specifically, to a highway bridge bearing capacity detection device. Background Art

[0002] Nowadays, with the rapid development of society, more and more highway bridges are being built. In the construction of highway bridges, the bearing capacity of highways and bridges plays a vital role in driving safety. The longer the highway bridge is in use, the more likely it is to bend and crack. Therefore, before the construction of the highway bridge project begins, it is generally necessary to conduct a bearing capacity test on the prefabricated road panels to predict the compressive strength of the highway bridge pavement after completion, and at the same time, to discover in advance the safety hazards that may exist after the highway bridge is put into use.

[0003] Chinese patent authorization announcement number: CN219475210U provides a highway bridge bearing capacity detection device, which includes a base, the upper surface of the base is fixedly connected to a side plate, the inner walls on both sides of the side plate are rotatably connected to a threaded rod, the surface of the threaded rod is sleeved with a sliding block, one end of the sliding block is fixedly connected to a clamping block, one side surface of the clamping block is fixedly connected to a spring at each of the four corners, and one end of the spring is fixedly connected to a pad.

[0004] However, in the above patent, the size of the pressure plate is relatively fixed, and the force-bearing area of ​​the sample cannot be changed, resulting in that the sample can only be squeezed at a fixed pressure when being squeezed, and the pressure on the sample cannot be increased or decreased by changing the force-bearing area of ​​the sample, resulting in a small detection range, inconvenience, and limitations in use.

[0005] Therefore, in order to solve the above problems, a highway bridge bearing capacity detection device is proposed. Utility Model Content

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] In this solution, when the turntable rotates, it will drive the turntable to rotate as well. As the turntable continues to rotate, the arc plate will gradually be inserted into the interior of the arc groove. Because the sizes of the four pressure blocks under the fixed block are different, the pressure blocks with large areas exert less pressure on the building bridge sample. On the contrary, the pressure blocks with small areas exert greater pressure on the building bridge sample. Therefore, by rotating the turntable, the purpose of replacing the pressure blocks of unqualified sizes is achieved, thereby expanding the detection range of building bridge samples.

[0028] Example:

[0029] See also Figure 1-4A device for detecting the bearing capacity of a highway bridge comprises a base 1, a support rod 11 being fixedly connected to the top of the base 1, a mounting plate 12 being fixedly connected to the top of the support rod 11, a turntable 16 being rotatably connected to the bottom of the mounting plate 12, a fixed block 17 being slidably connected to the inside of the turntable 16, an arc-shaped plate 2 being fixedly connected to the top of the fixed block 17, a hydraulic cylinder 21 being fixedly connected to the top of the mounting plate 12, an output end of the hydraulic cylinder 21 passing through the mounting plate 12 and being located below the mounting plate 12, an arc-shaped slot 22 being provided at the output end of the hydraulic cylinder 21, the arc-shaped plate 2 being slidably connected to the arc-shaped slot 22, and four fixed There are pressure blocks 26 fixedly connected to the bottom of the fixed block 17, and the sizes of the four pressure blocks 26 are all different. In this solution, when the turntable 16 rotates, it will drive the turntable 16 to rotate. As the turntable 16 continues to rotate, the arc plate 2 will gradually be inserted into the interior of the arc groove 22. Because the sizes of the four pressure blocks 26 under the fixed block 17 are all different, the pressure blocks 26 with large areas exert less pressure on the building bridge sample. On the contrary, the pressure blocks 26 with small areas exert greater pressure on the building bridge sample. Therefore, the purpose of replacing the pressure blocks 26 of different sizes is achieved by rotating the turntable 16.

[0030] See also Figure 1-4 A number one gear 13 is fixedly connected to the top of the turntable 16, and a number two gear 14 is engaged with one side of the number one gear 13. The number two gear 14 is rotatably connected to the bottom of the mounting plate 12. In this solution, when the number two gear 14 rotates, it will drive the number one gear 13 to rotate, and when the number one gear 13 rotates, it will drive the turntable 16 to rotate.

[0031] See also Figure 1-4 A No. 1 motor 15 is fixedly connected to the top of the mounting plate 12. The output end of the No. 1 motor 15 passes through the mounting plate 12 and is fixedly connected to the No. 2 gear 14. In this solution, the No. 1 motor 15 provides power for the rotation of the No. 2 gear 14.

[0032] See also Figure 1-4 The internal sliding connection of the fixed block 17 is connected to the limiting block 18, and a spring 19 is provided between the limiting block 18 and the inside of the fixed block 17. In this solution, since the limiting block 18 is a middle convex structure, when relative sliding occurs between the fixed block 17 and the turntable 16, the limiting block 18 will be squeezed by the turntable 16, causing the limiting block 18 to slide inside the fixed block 17. Since the elastic coefficient of the spring 19 is large, when the convex part of the limiting block 18 is located above the turntable 16, the limiting block 18 can complete the limitation between the fixed block 17 and the turntable 16 to prevent the fixed block 17 from falling.

[0033] See also Figure 1-4A special-shaped vise 23 is provided above the base 1, and a No. 2 motor 24 is fixedly connected to the top of the base 1. The No. 2 motor 24 is transmission-connected to the special-shaped vise 23. In this solution, when the No. 2 motor 24 is started, it will drive the two special-shaped vises 23 to move closer to or away from each other.

[0034] See also Figure 1-4 , a reinforcing rib 25 is provided above the turntable 16 . In this solution, the reinforcing rib 25 can enhance the structural strength of the turntable 16 .

[0035] Working principle: After the staff places the building bridge sample between the two special-shaped vises 23, the No. 2 motor 24 is started. After the No. 2 motor 24 is started, it will drive the two special-shaped vises 23 to complete the clamping of the sample, and then start the hydraulic cylinder 21 to press the output end of the hydraulic cylinder 21 downward, thereby driving the pressure block 26 to press down to complete the extrusion of the building bridge sample. If it is necessary to replace the pressure blocks 26 of different specifications and sizes, the staff can start the No. 1 motor 15. When the No. 1 motor 15 is started, it will drive the turntable 16 to rotate. When the turntable 16 rotates, it will drive the turntable 16 to rotate. As the turntable 16 continues to rotate, the arc plate 2 will gradually be inserted into the interior of the arc groove 22. Because the sizes of the four pressure blocks 26 under the fixed block 17 are different, the pressure blocks 26 with a large area exert less pressure on the building bridge sample. On the contrary, the pressure blocks 26 with a small area exert greater pressure on the building bridge sample. Therefore, the purpose of replacing the pressure blocks 26 of different specifications and sizes is achieved by rotating the turntable 16.

Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
