[0002] With the acceleration of urbanization and the continuous advancement of transportation construction, road and bridge engineering plays a vital role in modern society. As a key testing equipment, road and bridge bearing capacity test and detection devices are gradually moving towards intelligence and automation. Modern road and bridge bearing capacity test and detection devices use advanced sensing technology and data processing technology. They can monitor the load conditions in real time and provide accurate test results through data analysis and processing. Traditional devices have complex structures and are not very convenient to use, while modern devices are more compact and portable, and can be tested anytime and anywhere, greatly improving the flexibility and efficiency of work.

[0003] When the detection device is used at the construction site, the precast slabs for road and bridges need to be tested for bearing capacity, so the precast slabs for road and bridges need to be clamped and fixed. Otherwise, the gravity plates are frequently stacked on the precast slabs. Once the precast slabs are offset due to the downward pressure of the gravity plates, errors will occur in the bearing capacity of the static load test of the precast slabs. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of 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.

[0024] Example 1: Please refer to Figures 1 to 4 :

[0025] The utility model proposes a road and bridge bearing capacity test detection device, comprising: a connecting bearing plate 1; a groove is provided in the middle of the top of the connecting bearing plate 1; a load-bearing sensor 101 is installed at the groove in the middle of the connecting bearing plate 1; the top of the load-bearing sensor 101 is in contact with the road and bridge prefabricated plate 206, and limiting grooves 102 are evenly provided at both ends of the connecting bearing plate 1; bearing blocks 2 are slidably installed at both ends of the connecting bearing plate 1, and a through rectangular hole is provided at the lower end of the bearing block 2; the connecting bearing plate 1 is inserted into the rectangular holes at the lower ends of the two bearing blocks 2, and fixed vertical plates 3 are fixedly installed at the tops of the two bearing blocks 2, and a through threaded hole is provided in the middle of the fixed vertical plates 3; and through guide holes are provided at both ends of the two fixed vertical plates 3.

[0026] Among them, a through circular hole is opened in the middle of the two side walls of the two bearing blocks 2, and a through spring limiting column 203 is respectively inserted in the round holes of the two fixing plates 202, and the lower end of the spring limiting column 203 is inserted into the corresponding limiting groove 102 to fix and limit the connection of the bearing plate 1. The lower ends of the two side walls of the two bearing blocks 2 are respectively fixedly installed with side plates 201, and the two ends of the side plates 201 are respectively inserted with through threaded columns. The threaded columns on the side plates 201 are rotated and inserted into the ground to firmly limit the side plates 201 and the bearing blocks 2 to prevent the bearing blocks 2 from shaking and tilting when touched. The side walls of the two bearing blocks 2 facing away from one end are respectively fixedly installed with fixed plates 202, and the upper ends of the spring limiting columns 203 are fixedly installed with baffles 204. Pull rings are fixedly installed at the top of the two baffles 204. Grab the pull ring on the baffle 204 and lift it upward, and the lower end of the spring limit column 203 will be pulled out of the limit groove 102. Then grab the connecting bearing plate 1 and slide it left and right to adjust the position of the load-bearing sensor 101. Bearing slots 205 are respectively opened at the upper ends of the opposite ends of the two bearing blocks 2, and road and bridge prefabricated panels 206 are horizontally placed at the two bearing slots 205. When the road and bridge prefabricated panels 206 to be tested are relatively long, multiple gravity boxes 207 can be placed. A gravity box 207 is placed in the middle of the top of the road and bridge prefabricated panel 206, and the bottom of the inner cavity of the gravity box 207 is evenly stacked with gravity plates 208. The gravity specifications of each gravity plate 208 are the same, which is convenient for calculating the gravity of the stacked gravity plates 208.

[0027] Among them, threaded rods 301 are rotatably inserted in the threaded holes in the middle of the two fixed vertical plates 3, and fastening rings 302 are rotatably installed on the threaded rods 301. Anti-slip grooves are provided on the side walls of the outer ends of the two fastening rings 302. Control disks 303 are fixedly installed on the back ends of the two threaded rods 301, and short columns are fixedly installed on the annular side walls of the control disks 303. The short columns on the control disks 303 are grasped for easy rotation. The control disks 303 are grasped and rotated to move the two threaded rods 301 in opposite directions. At this time, the clamping plates 305 on the two threaded rods 301 will also move in opposite directions. The side walls of the opposite ends of the two clamping plates 305 are used to clamp and fix the road and bridge prefabricated panels 206. When the road and bridge prefabricated panels 206 are touched or heavy, When the force plate 208 is pressed down, it will not tilt sideways, thereby stably detecting the static load of the road and bridge prefabricated panel 206. Bearing rings 304 are respectively installed at the opposite ends of the two threaded rods 301, and clamping plates 305 are fixedly installed at the outer rings of the two bearing rings 304 at the opposite ends. Guide rods 306 parallel to each other are fixedly installed on the side walls of the two clamping plates 305 facing away from one end. The guide rods 306 slide through the guide holes of the fixed vertical plate 3. When the clamping plate 305 slides left and right, the guide rods 306 are restricted by the guide holes of the fixed vertical plate 3, and the clamping plate 305 can only slide left and right to prevent the clamping plate 305 from deviating or tilting when sliding left and right. The two clamping plates 305 cannot firmly clamp the gravity box 207.

[0028] Embodiment 2, based on embodiment 1, as Figure 1 and Figure 4 As shown, side panels 201 are fixedly installed at the lower ends of the two side walls of the two supporting blocks 2, and threaded columns are inserted at both ends of the side panels 201. The threaded columns are replaced with fixed plugs, and the lower ends of the fixed plugs are opened into a conical structure. When the side panels 201 and the supporting blocks 2 need to be fixed, the lower ends of the fixed plugs are cone-shaped and inserted into the ground to reduce resistance, and it is convenient to insert them into the ground to firmly restrict the side panels 201 and the supporting blocks 2, so that the supporting blocks 2 will not shake when touched, thereby firmly detecting the bearing capacity of the road and bridge prefabricated slab 206.

[0029] The working principle of this embodiment is as follows: when in use, first place the two ends of the road bridge prefabricated plate 206 at the bearing notches 205 at the two ends, the top of the load-bearing sensor 101 is in contact with the road bridge prefabricated plate 206, then insert the lower end of the spring limit column 203 into the corresponding limit groove 102, and fix the connection bearing plate 1, then rotate the threaded column on the side plate 201 and insert it into the ground, firmly limit the side plate 201 and the bearing block 2, and grab the control panel 30. The two threaded rods 301 are rotated and moved in opposite directions. At this time, the clamping plates 305 on the two threaded rods 301 will also move in opposite directions. The side walls of the two clamping plates 305 facing one end are used to clamp and restrict the road bridge prefabricated plate 206. Then, the gravity box 207 and the gravity plate 208 are placed on the road bridge prefabricated plate 206. When the road bridge prefabricated plate 206 is touched or the gravity plate 208 is pressed down, it will not tilt sideways, thereby stably detecting the static load of the road bridge prefabricated plate 206.
