The hand-push grip is located at the lower right of the slidable steel plate. The two are connected by welding. The vertical pole 10 is provided with two folding shafts 14, which are located on the left and right sides. The four vertical poles 10 are all placed above the base support 18. There are two layers of lateral steel plates arranged along the main steel beam direction of the unloading platform, namely the outer steel plate 12 and the inner steel plate 11. The thickness of the inner steel plate 11 is half of the thickness of the outer steel plate 12. The unloading platform pedal 13 is placed between the inner steel plates 11. The main steel beam 9 is welded to the secondary steel beam 7, a main steel beam slide rail 17 is welded above the main steel beam 9, a base support 18 is welded above the secondary steel beam 7, an outer steel plate pulley 16 is welded to the bottom of the outer steel plate 12, and a folding axis is provided at three quarters of the outer steel plate 12, and a groove is provided at the end of the outer steel plate 12 along the direction of the secondary steel beam. At the same time, when the outer steel plate 12 of the present invention slides to the end of the main steel beam 9, the outer steel plates 12 on the left and right sides are folded 90 degrees respectively to achieve perfect docking of the grooves and fixed with bolts. At the same time, the main steel beam 9 and the outer steel plate 12 are also fixed with bolts 8. There are two inner steel plates 11, which are symmetrically distributed and placed above the secondary steel beam and welded to the contact with the outer steel plate 12.

[0035] The four upright poles 10 are all made of steel pipes, the hand-pushing grip 6 is also made of steel pipes, and the slide rails are all provided with grooves.

[0036] The slide rail needs to pass through the vertical pole 10, and the contact part between the two is fixed by iron wire, so circular holes need to be reserved at the corresponding positions of the vertical poles. Each vertical pole has two circular holes reserved. The upper and lower spacing of the holes is the distance between the two slide rails. The cross bar 15 and the folding axis 14 are prefabricated and connected together by welding with the vertical pole 10.

[0037] The outer steel plate 12 of the unloading platform arranged along the main steel beam 9 is fixed to the main steel beam 9 by bolts 8 and has no connection with the vertical pole. The inner steel plate 11 only plays an isolation role, so the inner steel plate 11 only needs to have no connection with the vertical pole 10. The inner and outer steel plates have the same height, and the ratio of the inner or outer steel plate height to the vertical pole height is 1:2 to 1:2.5.

The present invention can be installed when the unloading platform is prefabricated or after the unloading platform is installed on site. The assembled unloading platform and its head protection device take into account that workers will basically not walk to the end of the unloading platform when using the unloading platform for hoisting operations. In order to save materials and reduce the weight of the unloading platform, the present invention sets the head protection device to three quarters of the total length of the unloading platform. There are 4 vertical poles 10, of which 2 vertical poles are fixed at two corners of the unloading platform, and the other 2 vertical poles are fixed at three quarters of the length of the unloading platform. There are secondary steel beams 7 under the 4 vertical poles 10, and the 4 vertical poles 10 are all left with holes for the first slide rail 1 and the second slide rail 4 to pass through, and the interface is fixed with iron wire. The head protection device has a folding shaft 14, and the folding shafts 14 are connected by a pre-welded cross bar 15, which is easy to carry. When installing, you only need to open the folding shaft to the maximum, and then place the 4 vertical poles on the base support 18 respectively, and finally place the slidable steel plate 3 and the fixed steel plate 2 on the slide rails respectively. The fixed steel plate 2 is provided with a groove and can be directly mounted on the slide rail 1. The fixed steel plate 2 occupies one quarter of the length of the unloading platform. The vertical rod 10 has no connection with the outer steel plate 12 and the inner steel plate 11. The bottom surface of the vertical rod 10 and the contact part of the secondary steel beam 7 are also connected through the base support 18. The slidable steel plate 3 occupies one quarter of the length of the unloading platform.

[0041] The remaining quarter length is to ensure that the tower crane can work normally on the unloading platform, and nothing is set. The slide rail is divided into two layers, the first slide rail 1 supports the fixed steel plate 2, and the second slide rail 4 supports the slidable steel plate 3. The fixed steel plate is provided with a groove and can be directly mounted on the slide rail. Figure 8 As shown, the length of the fixed steel plate 2 is one-fourth of the length of the unloading platform, and the width is 10 cm wider than the width between the vertical poles 10, wherein the width of each side is respectively extended by 5 cm. The second slide rail 4 interacts with the slidable steel plate 3 through the movable plate pulley 5, wherein the movable plate pulley 5 is 4 in total, symmetrically distributed, and connected to the slidable steel plate 3 by welding. The length of the slidable steel plate 3 is one-half of the length of the unloading platform, and the width is 10 cm wider than the width between the vertical poles, wherein the width of each side is respectively extended by 5 cm. The slide rail needs to pass through the vertical pole 10, and the contact part between the two is fixed by wire, so circular holes need to be reserved at the corresponding positions of the vertical poles, and each vertical pole has 2 circular holes reserved, and the upper and lower spacing of the holes is the distance between the two slide rails. The hand-push grip 6 is welded to the lower right side of the slidable steel plate 3. The main steel beam slide rail 17 is welded on the main steel beam 9, the base support 18 is welded on the secondary steel beam 7, the outer steel plate pulley 16 is welded on the bottom of the outer steel plate 12, and a folding shaft is provided at three quarters of the outer steel plate 12. A groove is provided at the end of the outer steel plate 12 along the direction of the secondary steel beam. At the same time, when the outer steel plate 12 of the present invention slides to the end of the main steel beam 9, the outer steel plates 12 on the left and right sides are folded 90 degrees respectively to achieve perfect docking of the grooves and fixed with bolts. The main steel beam 9 and the outer steel plate 12 are also fixed with bolts 8. In order to prevent the vertical pole 10 from being hit by materials during tower crane operation, the unloading platform has two layers of lateral steel plates arranged along the main steel beam direction. The outer steel plate 12 plays a protective role, and the inner steel plate 11 plays a role in isolating the vertical pole, and the thickness of the inner steel plate 11 is half the thickness of the outer steel plate 12. The outer steel plate 12 arranged along the main steel beam 9 of the unloading platform is fixed to the main steel beam 9 by bolts 8. The inner steel plate 11 only plays an isolating role and can also make the vertical pole more stable. The inner steel plate 11 and the components in contact with it can be welded. After the inner steel plate 11 and the outer steel plate 12 are installed, the unloading platform pedal 13 is laid according to the size requirements.
