Description

Technical Field

[0001] This utility model relates to the field of highway bridge load-bearing capacity testing technology, and in particular to a highway bridge load-bearing capacity testing device. Background Technology

[0002] Nowadays, with the rapid development of society, more and more highway bridges are being built. In the construction of highway bridges, the load-bearing capacity of highways and bridges plays a crucial role in driving safety. The longer a highway bridge is used, the more likely it is to bend or crack. Therefore, before the construction of a highway bridge project begins, it is generally necessary to conduct load-bearing capacity tests on the precast road panels.

[0003] Announcement No. (CN219475210U) discloses a highway bridge load-bearing capacity testing device. After the cast-in-place sample is fixed, the first motor is started, which drives the transmission rod to rotate, thereby driving the driven gear to rotate, which in turn drives the screw to rotate inside the sleeve, which in turn drives the screw to move downward, which in turn drives the fixed plate to move downward, and finally drives the pressure plate to descend and squeeze the cast-in-place sample. By continuously increasing the power of the first motor, the load-bearing capacity of the cast-in-place is tested. However, the test may cause the cast-in-place sample to break. The above device is not convenient for cleaning the broken cast-in-place sample and needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a highway bridge load-bearing capacity testing device in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A highway bridge load-bearing capacity testing device includes a moving mechanism and a testing mechanism for testing the load-bearing capacity of highway bridge samples, the testing mechanism being fixed above the moving mechanism.

[0007] The testing mechanism includes a fixed rod, a testing component mounted on the fixed rod, a fixed platform, a collection box mounted inside the fixed platform, a testing chamber mounted on the fixed platform, a door mounted at the front of the testing chamber, a hydraulic cylinder fixed above the testing chamber, a pressure plate fixed to the telescopic end of the hydraulic cylinder, a fixed shell mounted on both sides of the testing chamber, a motor mounted above the fixed shell, a threaded rod mounted at the motor output end, a lifting block located outside the threaded rod, a rotating rod fixed to the side of the lifting block, a movable block fixed below the rotating rod, and a movable plate fixed to the side of the movable block.

[0008] Preferably, the moving mechanism includes a moving plate, and moving wheels are mounted below the moving plate.

[0009] Preferably, the testing mechanism is equipped with a support mechanism, which includes a fixed block, an electric push rod installed at the front and rear of the fixed block, a bent rod installed at the end of the electric push rod away from the fixed block, and a support plate fixed on the bent rod.

[0010] Preferably, the movable plate is made of stainless steel, and the movable wheels are rotatably connected to the movable plate.

[0011] Preferably, the pressure plate is made of hard alloy, and the motor is connected to the fixed housing by bolts.

[0012] Preferably, the electric push rod is connected to the fixed block by bolts, and the support plate is welded to the bent rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By setting up a testing mechanism, highway bridge samples are placed on a movable plate. After placement, the box door is closed and the hydraulic cylinder is activated. The hydraulic cylinder moves the pressure plate downward, which squeezes the highway bridge sample, thus testing its load-bearing capacity. The test will cause the highway bridge sample to break. After the test, the pressure plate returns to its original position, and the motor is started. The motor drives the threaded rod to rotate, which in turn drives the lifting block to descend. The descending lifting block drives the rotating rod to rotate, which in turn drives the movable block to move. The movable block drives the movable plate to move away from each other. When the movable plate reaches the corresponding position, the motor stops running. At this point, all the broken highway bridge samples fall into the collection box. This method can automatically clean up broken highway bridge samples, effectively improving the efficiency of the device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5As shown, a highway bridge load-bearing capacity testing device includes a moving mechanism 1 and a testing mechanism 2 for testing the load-bearing capacity of a highway bridge sample. The testing mechanism 2 is fixed above the moving mechanism 1.

[0027] In this utility model, the moving mechanism 1 includes a moving plate 101 and a moving wheel 102. The moving wheel 102 is installed below the moving plate 101. The moving plate 101 is made of stainless steel, and the moving wheel 102 is rotatably connected to the moving plate 101. The setting of the moving wheel 102 makes the movement of the device more convenient.

[0028] In this utility model, the detection mechanism 2 includes a fixed rod 201, a fixed platform 202, a collection box 203, a detection box 204, a box door 205, a hydraulic cylinder 206, a pressure plate 207, a fixed shell 208, a motor 209, a threaded rod 210, a lifting block 211, a rotating rod 212, a movable block 213, and a movable plate 214. The fixed platform 202 is installed above the fixed rod 201, the collection box 203 is installed inside the fixed platform 202, the detection box 204 is installed above the fixed platform 202, and the box door 205 is installed inside the detection box. At the front of 204, hydraulic cylinder 206 is fixed above the detection box 204, pressure plate 207 is fixed to the telescopic end of hydraulic cylinder 206, fixed shell 208 is installed on both sides of detection box 204, motor 209 is installed above fixed shell 208, threaded rod 210 is installed at the output end of motor 209, lifting block 211 is located outside threaded rod 210, rotating rod 212 is fixed to the side of lifting block 211, movable block 213 is fixed below rotating rod 212, and movable plate 214 is fixed to the side of movable block 213; the material of pressure plate 207 is... Made of hard alloy, the motor 209 is bolted to the fixed housing 208. The highway bridge sample is placed on the movable plate 214. After placement, the box door 205 is closed and the hydraulic cylinder 206 is activated. The hydraulic cylinder 206 drives the pressure plate 207 to descend, squeezing the highway bridge sample to test its load-bearing capacity. This test causes the sample to break. After the test, the pressure plate 207 is returned to its original position, and the motor 209 is activated. The motor 209 drives the threaded rod 210 to rotate, which in turn drives the lifting block 211 to descend. The descending lifting block 211 drives the rotating rod 212 to rotate, which in turn moves the movable block 213. The movable block 213 then moves the movable plate 214, causing the two movable plates 214 to move away from each other. When the movable plates 214 reach their respective positions, the motor 209 stops. At this point, all the broken highway bridge samples fall into the collection box 203. This method automatically cleans up the broken highway bridge samples, effectively improving the device's performance.

[0029] In this invention, a support mechanism 3 is installed on the detection mechanism 2. The support mechanism 3 includes a fixed block 301, an electric push rod 302, a bent rod 303, and a support plate 304. The electric push rod 302 is installed at the front and rear of the fixed block 301, and the bent rod 303 is installed at the end of the electric push rod 302 away from the fixed block 301. The support plate 304 is fixed on the bent rod 303. The electric push rod 302 is connected to the fixed block 301 by bolts, and the support plate 304 is welded to the bent rod 303. The support plate 304 can support the connection between the two movable plates 214, thus effectively reducing the probability of deformation of the movable plates 214.

[0030] In the above structure: When using the device, the highway bridge sample is placed on the movable plate 214. After placement, the box door 205 is closed and the hydraulic cylinder 206 is activated. The hydraulic cylinder 206 moves, causing the pressure plate 207 to descend. The descending pressure plate 207 compresses the highway bridge sample, thus testing its load-bearing capacity. The test may cause the highway bridge sample to break. After the test is completed, the pressure plate 207 is returned to its original position, and the electric push rod 302 is extended. The extension of the electric push rod 302 causes the bent rod 303 and the support plate 304 to move. 04 After being removed from the fixed platform 202, the electric push rod 302 stops running, and the motor 209 is started. The motor 209 drives the threaded rod 210 to rotate, which in turn drives the lifting block 211 to descend. The descending of the lifting block 211 drives the rotating rod 212 to rotate, which in turn drives the movable block 213 to move. The movable block 213 drives the movable plate 214 to move, and the two movable plates 214 move away from each other. When the movable plate 214 moves to the corresponding position, the motor 209 stops running. At this time, all the broken highway bridge samples fall into the collection box 203.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
