[0020] Combined with attachment Figure 1 To the attached Figure 6 The support column 5 is welded on the support column 5, and two cross beams 6 are welded on the support column 5. Two first fixing plates 7 and a plurality of second fixing plates 8 are installed on the two cross beams 6. The two first fixing plates 7 are respectively arranged on both sides of the plurality of second fixing plates 8. A platform 9 is installed above the two first fixing plates 7 and the plurality of second fixing plates 8. A plurality of threaded holes are opened at the bottom of the platform 9, and threaded holes matching the platform 9 are opened on the upper surfaces of the plurality of second fixing plates 8 for easy installation and disassembly. A first groove 10 is opened on the two first fixing plates 7, a clamping device 11 is installed in the first groove 10, a stabilizing device 111 is installed on the clamping device 11, and a fixing device 12 is installed under the two cross beams 6.

[0021] The clamping device 11 includes a first motor 13, which is fixedly installed at the rear end of the first groove 10. A first screw 14 is installed at the output shaft end of the first motor 13. The first screw 14 includes a first thread segment and a second thread segment. The first thread segment and the second thread segment are designed as reverse threads. Clamps 15 are symmetrically installed between the two first thread segments and the two second thread segments. A second groove 112 is opened on the two clamps 15, and a stabilizing device 111 is installed in the second groove 112.

[0022] Specifically, the platform 9 is placed above the first fixed plate 7 and several second fixed plates 8 by a crane. Since the placement position is not fixed, the platform 9 needs to be placed in a position that is convenient for installation. At this time, the first motor 13 is started to drive the first screw 14 to rotate. Since the first thread segment and the second thread segment on the first screw 14 are designed as reverse threads, the first screw 14 will drive the two clamping plates 15 to move relative to each other while rotating, thereby fixing the position of the platform, so that the threaded holes of the platform 9 correspond to the threaded holes of several second fixed plates 8, which is convenient for installation and does not require manual adjustment of the position of the platform 9.

[0023] The stabilizing device 111 includes a second motor 114, which is fixedly installed on the left side of the second groove 112. A second screw 115 is installed on the output shaft end of the second motor 114. The second screw 115 includes a third thread segment and a fourth thread segment. The third thread segment and the fourth thread segment are designed as reverse threads. Baffles 116 are symmetrically installed on the third thread segment and the fourth thread segment.

[0024] Specifically, the platform 9 is placed above the first fixed plate 7 and several second fixed plates 8, and is fixed front and back by the clamping device 11. Then, the second motor 114 is started to drive the second screw 115 to rotate. Since the third thread segment and the fourth thread segment on the second screw 115 are designed as reverse threads, the second screw 115 rotates while driving the two baffles 116 to move relative to each other, thereby adjusting the left and right position of the platform 9.

[0025] The fixing device 12 includes a rotating seat 16, on which a fixed cylinder 17 is rotatably installed. A rotating rod 18 is connected to the inside of the fixed cylinder 17 through an internal thread. A rotating seat 19 is installed at the end of the rotating rod 18 away from the fixed cylinder 17. A pad 20 is fixedly installed at the bottom of the rotating seat 19. A through hole is opened on the pad 20, and a ground nail 21 is provided in the through hole.

[0026] Specifically, the fixed cylinder 17 is rotated around the rotating seat 16, and then the pad 20 is rotated to rotate the rotating rod 18 out of the fixed cylinder 17. When the pad 20 contacts the ground, the rotation of the rotating rod 18 is stopped, and then the ground nail 21 is driven into the ground through the through hole to further support and stabilize the beam 6.

[0027] The length of the first fixing plate 7 is greater than the length of several second fixing plates 8, the width of the platform 9 is less than the length of several second fixing plates 8, and the length of the platform 9 is the same as the length of the beam 6. The design is reasonable and safer.

[0028] The clamping plates 15 are located above several second fixing plates 8. The positions of the two clamping plates 15 are symmetrical relative to the second fixing plates 8. The clamping plates 15 clamp and fix the platform 9 while also making the threaded holes on the platform 9 correspond to the threaded holes of the second fixing plates 8, which is convenient for installation.
