Description

Technical Field

[0001] The utility model belongs to the technical field of bridge detection, and in particular relates to a highway bridge bearing capacity detection device. Background Art

[0002] The structural form of the highway cross section is divided into surface layer, base layer, cushion layer and subbase layer. This overall pavement structure jointly bears the load from above the road surface. Due to the difference in road grades and materials, high-grade pavements have stronger bearing capacity and traffic capacity. In short, the bearing capacity of a highway is the ability of the highway to measure the size of the impact of vehicles. After the bridge is built, the bearing capacity of the highway bridge is tested by sampling.

[0003] In the Chinese patent with publication number CN215677908U, a device for testing the bearing capacity of highway bridges is mentioned. The bridge sample can be fixed by a fixing plate, thereby improving the stability of the bridge sample and ensuring the accuracy of its test data. The detection block can be squeezed by a motor, and the gravity of the load-bearing plate can be increased as needed by placing a rod, so as to facilitate the detection of the bridge sample. However, when the detection device is used, two fixing plates are used to clamp and fix the bridge sample, and the fixing plates are easy to loosen in the process of clamping the bridge sample, resulting in poor fixing effect of the bridge sample, thereby affecting the stability of the bridge sample and not being conducive to the device to detect the bridge sample.

[0004] In addition, the detection method of this detection equipment is generally to perform static extrusion on it through a press, and to simulate vehicles with different loads by changing the pressure of the press. However, the actual situation is that vehicles are in a dynamic driving process on the road, and static extrusion rarely occurs, resulting in certain differences between the test data and the actual situation.

DETAILED DESCRIPTION

[0025] 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.

[0026] Embodiment 1:

[0027] See also Figure 1 - Figure 4 As shown, a highway bridge bearing capacity detection device comprises:

[0028] A base 1, a support frame 2 is arranged on the outer wall of the base 1, a limit opening 4 is opened on the inner side of the support frame 2, and a controller 5 is fixedly connected to the outer wall of the base 1;

[0029] The detection mechanism 3 is arranged on the outer wall of the support frame 2. The detection mechanism 3 includes a hydraulic cylinder 31, a detection platen 32, a limit groove 33 and a limit block 34. The hydraulic cylinder 31 is connected to the outer wall of the support frame 2, the detection platen 32 is fixedly connected to the output end of the hydraulic cylinder 31, the limit groove 33 is arranged in the middle of the bottom end of the detection platen 32, the limit block 34 is fixedly connected to the bottom end of the detection platen 32, and a moving component is arranged on the inner side of the limit block 34;

[0030] The fixing mechanism 6 is arranged on the outer wall of the base 1. The fixing mechanism 6 includes a fixing box 61, a guide groove 62, a driver 63 and a forward and reverse screw rod 64. The fixing box 61 is inserted and fixedly connected to the outer wall of the base 1. The guide groove 62 is opened at the top of the fixing box 61. The driver 63 is fixedly connected to the outer wall of the fixing box 61. The forward and reverse screw rod 64 is movably connected to the inner side of the fixing box 61. The outer wall of the forward and reverse screw rod 64 is provided with a clamping assembly.

[0031] Depend on Figure 1 - Figure 3 It can be seen that the moving assembly includes an electric telescopic rod 35, a fixed frame 36, a movable shaft 37, a detection wheel 38 and a limit rod 39. The electric telescopic rod 35 is inserted and fixedly connected to the outer wall of the limit block 34, the fixed frame 36 is fixedly connected to the output end of the electric telescopic rod 35, the movable shaft 37 is movably connected to the inner side of the fixed frame 36, the detection wheel 38 is inserted and fixedly connected to the outer wall of the movable shaft 37, and the limit rod 39 is fixedly connected to the inner side of the limit block 34.

[0032] As can be seen from the above, the staff controls the hydraulic cylinder 31 to start through the controller 5, so that the hydraulic cylinder 31 pushes the detection platen 32 to move downward, and slides in the limit opening 4 through the limit block 34 to play a limiting role, which can improve the stability of the detection platen 32 during the downward movement, so that the detection wheel 38 can be stably pushed to move downward to contact the bridge sample and apply pressure to it, and then the staff controls the electric telescopic rod 35 to start through the controller 5, so that the fixed frame 36 can be pushed and pulled by the extension of the electric telescopic rod 35, and the fixed frame 36 can be guided and limited by the limit rod 39, so that the detection wheel 38 can be stably pushed to move left and right, so that the detection wheel 38 can use dynamic extrusion to detect the bridge sample, and then can simulate the dynamic driving process of vehicles with different loads on the road, thereby ensuring that the test data is consistent with the actual situation.

[0033] Specifically, refer to Figure 2 and Figure 3 As shown, the limit rods 39 are symmetrically distributed in two groups on the outer wall of the fixed frame 36, and the two limit rods 39 both penetrate the outer wall of the fixed frame 36. The bottom end of the detection wheel 38 is lower than the bottom end of the fixed frame 36. The limit blocks 34 are symmetrically distributed in two groups on the outer wall of the detection pressure plate 32, and the two limit blocks 34 are respectively slidably connected to the two limit openings 4, and the electric telescopic rod 35 and the hydraulic cylinder 31 are both electrically connected to the controller 5.

[0034] As can be seen from the above, the position movement of the fixed frame 36 can be limited by the limit rod 39, thereby ensuring the stability of the fixed frame 36 during the movement. The detection wheel 38 contacts the bridge sample while the fixed frame 36 does not contact it, which is beneficial to the dynamic movement detection of the detection wheel 38. The position movement of the detection pressure plate 32 can be limited by the limit block 34, thereby ensuring the stability of the detection pressure plate 32 during the movement.

[0035] Embodiment 2:

[0036] refer to Figure 4 As shown, the clamping assembly includes a fixing frame 65, a screw 66, a fixing clamp 67 and a notch 68. The fixing frame 65 is threadedly connected to the outer wall of the forward and reverse screws 64, the screw 66 is threadedly connected to the outer wall of the fixing frame 65, the fixing clamp 67 is movably connected to the bottom end of the screw 66, and the notch 68 is opened on the outer wall of the fixing clamp 67.

[0037] As can be seen from the above, the staff places the sample bridge sample on the base 1, and then the staff controls the driver 63 to start through the controller 5, so that the forward and reverse screws 64 simultaneously drive the two fixing frames 65 to move toward the middle, and make the fixing frames 65 slide in the guide groove 62 to improve stability, so that the two fixing frames 65 clamp the front and rear sides of the bridge sample, and then the staff manually rotates the screws 66 on the two fixing frames 65, thereby pushing the two fixing clamps 67 to move downward, so that the two fixing clamps 67 cooperate with the base 1 to clamp the upper and lower sides of the bridge sample, so that the detection equipment can fix and detect bridge samples of different sizes and thicknesses, so that the front and rear clamping combined with the upper and lower clamping can be adopted, and the bridge sample can be fixed more firmly, so that the bridge sample and the fixing frame 65 are not easy to move during the detection process, which effectively improves the stability of the bridge sample, which is beneficial for the detection equipment to detect the bearing capacity of the bridge sample.

[0038] Preferably, reference Figure 1 - Figure 4 As shown, the fixing frames 65 are symmetrically distributed in two groups on the outer walls of the positive and negative screw rods 64, the lower parts of the two fixing frames 65 are both configured as convex structures, and the two fixing frames 65 are both slidably connected to the guide grooves 62, the notches 68 are slidably connected to the side walls of the fixing frames 65, and the driver 63 is electrically connected to the controller 5.

[0039] As can be seen from the above, the convex structure of the fixing frame 65 can facilitate the guide groove 62 to limit it, and also facilitate the forward and reverse screw rods 64 to stably adjust the position of the fixing frame 65. The notch 68 can limit the fixing splint 67, so that the position of the fixing splint 67 can be movably limited, and the fixing splint 67 can only move up and down.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
