Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure inspection technology, specifically a steel structure length inspection device. Background Technology
[0002] A steel structure is an engineering structure constructed primarily of steel. It consists of steel beams, steel columns, steel trusses, and other components made of steel sections and plates, which are typically connected by welds, bolts, or rivets.
[0003] Before use, the length of steel structures needs to be measured. Existing measuring devices do not have the function of straightening steel structures during use. This causes the test results to be affected when the steel structure is tilted or bent, and thus cannot meet the usage requirements. In order to solve the above problems, a steel structure length measuring device is proposed. Summary of the Invention
[0004] To address the aforementioned issues, a steel structure length detection device is proposed.
[0005] This utility model provides the following technical solution: a steel structure length detection device, comprising a housing, an electric telescopic rod fixedly connected to the left side of the bottom of the housing, a rectangular plate fixedly connected to the bottom of the electric telescopic rod, a rotating shaft movably connected to the top of the rectangular plate, a cross bracket fixedly connected to the top of the rotating shaft, a horizontal plate fixedly connected to the bottom of the inner cavity of the housing, a connecting plate fixedly connected to the left side of the top of the housing, a first motor fixedly connected to the left side of the connecting plate, a lead screw fixedly connected to the output end of the first motor, an adjusting plate threadedly connected to the surface of the lead screw, a movable rod movably connected to one side of the adjusting plate, a connecting seat movably connected to one side of the movable rod, and a pressure plate fixedly connected to the bottom of the connecting seat.
[0006] Preferably, a pressure sensor is fixedly connected to the left side of the inner cavity of the housing, a fixing plate is fixedly connected to the right side of the pressure sensor, a second motor is provided on the right side of the housing, a crankshaft is fixedly connected to the output end of the second motor, an adjusting rod is movably connected to the surface of the crankshaft, a push plate is fixedly connected to one side of the adjusting rod, a distance sensor is fixedly connected to the top of the push plate, and a buzzer is fixedly connected to the right side of the top of the housing.
[0007] Preferably, the bottom of the rotating shaft is movably connected to the rectangular plate via a bearing, and support legs are fixedly connected to the four corners of the bottom of the housing.
[0008] Preferably, a slide rod is slidably connected to the rear side of the inner cavity of the adjusting plate, and the left side of the slide rod is fixedly connected to the fixing plate.
[0009] Preferably, each of the four corners of the top of the pressure plate is fixedly connected to a telescopic column, and the top of the telescopic column is fixedly connected to the shell.
[0010] Preferably, a mounting base is fixedly connected to one side of the second motor, and one side of the mounting base is fixedly connected to the housing.
[0011] The beneficial effects of this utility model are:
[0012] 1. In this utility model, the material is placed on the top of the horizontal plate, and then the first motor is started. The first motor drives the lead screw to rotate, the lead screw drives the adjusting plate to move, the adjusting plate drives the movable rod to move, the movable rod drives the connecting seat to move, the connecting seat drives the pressure plate to move, flattening the material. Then the pressure plate is returned to its original position, and the electric telescopic rod is started. The electric telescopic rod drives the rectangular plate to move, the rectangular plate drives the rotating shaft to move, the rotating shaft drives the cross bracket to move, and the cross bracket drives the material to rise to correspond with the fixed plate.
[0013] 2. This utility model starts the second motor, which drives the crankshaft to rotate. The crankshaft drives the adjusting rod to move, and the adjusting rod drives the push plate to move, thereby pushing the material to move and making the material contact the fixed plate. The fixed plate then squeezes the pressure sensor. After the two pressure sensors detect the same pressure value, the buzzer will sound. At this time, the second motor is stopped by the external PLC controller, and the distance sensor is activated to detect the distance between the fixed plate and the push plate. This distance is the same as the length of the material. Attached Figure Description

[0024] The specific function of this technical solution is as follows: the material is placed on the top of the horizontal plate 8, and then the first motor 10 is started. The first motor 10 drives the lead screw 11 to rotate, the lead screw 11 drives the adjusting plate 12 to move, the adjusting plate 12 drives the movable rod 13 to move, the movable rod 13 drives the connecting seat 14 to move, the connecting seat 14 drives the pressure plate 15 to move, flattening the material, and then the pressure plate 15 is returned to its original position.
[0025] Example 2:
[0026] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pressure sensor 6 is fixedly connected to the left side of the inner cavity of the housing 1, a fixing plate 7 is fixedly connected to the right side of the pressure sensor 6, a second motor 17 is provided on the right side of the housing 1, a crankshaft 18 is fixedly connected to the output end of the second motor 17, an adjusting rod 19 is movably connected to the surface of the crankshaft 18, a push plate 20 is fixedly connected to one side of the adjusting rod 19, a distance sensor 21 is fixedly connected to the top of the push plate 20, a buzzer 22 is fixedly connected to the right side of the top of the housing 1, a fixing seat is fixedly connected to one side of the second motor 17, and one side of the fixing seat is fixedly connected to the housing 1.
[0027] The specific function of this technical solution is as follows: The electric telescopic rod 2 is activated, which moves the rectangular plate 3. The rectangular plate 3 moves the rotating shaft 4, which in turn moves the cross bracket 5. The cross bracket 5 then lifts the material to align with the fixed plate 7. Subsequently, the second motor 17 is activated, which in turn rotates the crankshaft 18.

Then the pressure plate 15 is returned to its original position.
[0029] Start the electric telescopic rod 2, which moves the rectangular plate 3. The rectangular plate 3 moves the rotating shaft 4, which in turn moves the cross bracket 5. The cross bracket 5 lifts the material to align with the fixed plate 7. Then, start the second motor 17, which rotates the crankshaft 18. The crankshaft 18 moves the adjusting rod 19, which in turn moves the push plate 20, thus pushing the material to contact the fixed plate 7. The fixed plate 7 then presses against the pressure sensor 6. Once the two pressure sensors 6 detect the same pressure value, the buzzer 22 will sound. At this point, the external PLC controller stops the second motor 17 and starts the distance sensor 21, which detects the distance between the fixed plate 7 and the push plate 20. This distance is the same as the length of the material.
