[0034] In summary, the steel box girder pushing construction equipment for convenient high-altitude demolition is used. First, the bottom plate 7 is hoisted to the height of the base plate 4, and the bottom plate 7 is moved to allow the base plate 4 to be inserted between the limiting plates 8. The bottom plate 7 is placed on the base plate 4, so that the base plate 4 can provide support for the bottom plate 7. Then the electromagnet 1004 is powered on to adsorb the plug plate 1006 and compress the tension spring 1005. The telescopic rod 6 drives the mounting block 1002 to move, and the mounting block 1002 is inserted into the mounting slot 1001. After the mounting block 1002 is completely inserted into the mounting slot 1001, the electromagnet 1004 is powered off. The plug plate 1006 can rebound and be clamped into the insertion slot 1003 under the action of the tension spring 1005, so as to fix the mounting block 1002 in the mounting slot 1001. The telescopic rod 6 can drive the bottom plate 7 to move on the base plate 4 to the predetermined position through the mounting block 1002. When the bottom plate 7 moves on the base plate 4, the guide wheel 5 can assist the movement of the bottom plate 7 through the guide rail 9 and limit the movement of the bottom plate 7 to avoid the deflection of the bottom plate 7 during the movement. Then the jack 1208 drives the base 1301 to rise, and the support plate 1310 first contacts the bottom surface of the steel box girder. After the first pressure gauge 1311 detects the pressure, the lifting rod 1309 drives the support plate 1310 to descend synchronously with the rising of the base 1301, so as to avoid the support plate 1310 hindering the rising of the base 1301 driven by the jack 1208. When the support plate 1310 descends, it can drive the pressing plate 1312 to descend in the clamping slot 1303, and drive the clamping plate 1305 to slide in the base 1301 through the pressing slot 1306, and compress the top spring 1304, so that the clamping plate 1305 can drive the clamping plate 1307 to slide oppositely in the clamping slot 1303. When the clamping plate 1307 is tightly pressed on the side surface of the bottom of the steel box girder, the second pressure gauge 1308 detects the corresponding pressure value, and the lifting rod 1309 stops driving the support plate 1310 to descend. The support plate 1310 can cooperate with the clamping plate 1307 to clamp the steel box girder in a three-sided wrapping manner, so that the steel box girder can be evenly stressed during the pushing of the steel box girder, and the pushing process is stable. After clamping is completed, the jack 1208 continues to drive the base 1301 to rise to lift the steel box girder. After lifting is completed, the push-pull rod 1202 can drive the sliding plate 1204 to move in the bottom plate 7 to move the steel box girder horizontally. When the sliding plate 1204 moves, the sliding groove 1201 can limit the sliding plate 1204 to avoid the deviation of the sliding plate 1204 during the movement. The roller 1203 can assist the movement of the sliding plate 1204 to ensure the smooth movement of the sliding plate 1204. When the steel box girder is pushed, the calibrator 11 can emit a correction line to the bottom of the steel box girder to make the calibration line coincide with the reference line of the bottom of the steel box girder. If the steel box girder deviates during the pushing process, the telescopic rod 6 can drive the bottom plates 7 on both sides to move on the base plate 4 through the mounting block 1002 until the calibration line coincides with the reference line again. When the steel box girder is corrected, the steel box girder can drive the jack 1208 to drive the rotating plate 1207 to rotate on the sliding plate 1204 through the clamping assembly 13,The jack 1208 is prevented from being damaged by radial force, the stability of the jack 1208 is maintained, the imbalance of the jack 1208 is avoided to cause the steel box girder to be inclined or even to be dumped, when the rotating plate 1207 rotates, the sliding plate 1204 can limit the rotating plate 1207 through the rotating groove 1205 and the rotating table 1206, so that the rotating plate 1207 is prevented from falling off the sliding plate 1204, after the jacking is completed, the base 1301 can be lowered by the jack 1208, the readings of the first pressure gauge 1311 and the second pressure gauge 1308 are zeroed, the supporting plate 1310 is reset by the lifting rod 1309, the clamping plate 1307 is reset by the clamping plate 1305 under the action of the top spring 1304, the steel box girder is clamped next time, when the clamping plate 1305 moves, the clamping plate 1305 is limited by the clamping cavity 1302, so that the clamping plate 1305 is prevented from being inclined during the movement, after use, the bottom plate 7 is pushed to the end of the base plate 4 by the telescopic rod 6, then the lifting device grabs the bottom plate 7, the electromagnet 1004 is electrified, the plug-in plate 1006 is pulled out of the plug-in groove 1003, the mounting block 1002 is reset by the telescopic rod 6, and the lifting device can disassemble the bottom plate 7 from the base plate 4.
