[0022] The following further illustrates the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings and embodiments. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.
[0023] Example:
[0024] like Figure 1 - Figure 3 As shown, the utility model provides a foldable rotating continuous beam mid-span joint steel shell device, comprising a preset bottom plate 1, with a set of rotation adjustment components 2 installed at both ends of the preset bottom plate 1, the rotation adjustment component 2 comprising a rotation adjustment seat 21 fixed to the surface of the preset bottom plate 1 by bolts, and a connecting rotating plate 22 installed on one side of the interior of the rotation adjustment component 2 by a rotating shaft, a bottom steel shell 3 is fixed between the two sets of connecting rotating plates 22, a side steel shell connector 4 is installed at the bottom end of the rotation adjustment component 2, and a side steel shell 5 is installed at the movable end of the side steel shell connector 4;
[0025] The bottom steel shell 3 is supported by the connecting rotating plate 22 and can be turned toward the preset bottom plate 1 , and the side steel shell 5 is supported by the side steel shell connecting piece 4 and can be rotated toward the preset bottom plate 1 .
[0026] The preset bottom plate 1 is installed at the end of the beam end, and the side of the preset bottom plate 1 is flush with the end of the beam end. After the bottom steel shell 3 is connected to the rotation adjustment component 2 and installed in place, the side of the bottom steel shell 3 can fit smoothly with the preset bottom plate 1 and both ends, thereby ensuring the flatness of the connection between the bottom steel shell 3, the preset bottom plate 1 and the beam end.
[0027] A vertical groove is opened on the side of the rotation adjustment seat 21 toward the bottom steel shell 3, and the connecting rotating plate 22 is located in the vertical groove. The bottom end of the connecting rotating plate 22 is flush with the bottom end of the preset bottom plate 1. After the bottom steel shell 3 is connected to the connecting rotating plate 22, the connecting rotating plate 22 can serve as a support for the rotation of the bottom steel shell 3, so that the bottom steel shell 3 can be rotated around the rotation adjustment seat 21 through the connecting rotating plate 22, so that the bottom steel shell 3 is stored in the beam end, and then unfolded after the rotation and alignment are completed at the beam end to fill the empty part.
[0028] A transverse groove is formed on the outer side of the rotation adjustment seat 21, and the side steel shell connector 4 is installed in the transverse groove through a rotating shaft. The side steel shell connector 4 includes a rotation adjustment plate 41, a screw 42, a sliding sleeve 43 and a plug rod 44;
[0029] The rotation adjustment plate 41 is installed in the transverse groove through the rotating shaft, the screw 42 is fixed to the end of the rotation adjustment plate 41, the sliding sleeve 43 is sleeved on the outer upper end of the screw 42, and the plug-in rod 44 is welded to the middle of the outer wall of the sliding sleeve 43. After the bottom steel shell 3 is flipped and stored, the side steel shell 5 is nested and connected with the plug-in rod 44. Then, by rotating the rotation adjustment plate 41, the rotation adjustment plate 41 can drive the plug-in rod 44 and the side steel shell 5 installed on the plug-in rod 44 to move to the front of the rotation adjustment seat 21. At the same time, the side steel shell 5 can be further tilted with the plug-in rod 44 as the rotation axis to reduce the occupation of the lateral space and will not hinder the rotation and alignment process of the bridge.
[0030] The outer wall of the rotation adjustment plate 41 fits with the inner wall of the transverse groove. The length of the rotation adjustment plate 41 is longer than the transverse groove. During the rotation process, the rotation adjustment plate 41 is always clamped and supported by the transverse groove, which prevents the rotation adjustment plate 41 from shaking up and down and improves the stability of the rotation adjustment plate 41 during the rotation with the beam end.
[0031] The inner wall of the side steel shell 5 is provided with a notch that cooperates with the plug-in rod 44. The plug-in rod 44 is cylindrical, and the length of the plug-in rod 44 is longer than the notch of the plug-in rod 44. Through the plug-in connection, the side steel shell 5 can be rotated around the plug-in rod 44, so that the upper end or lower end of the plug-in rod 44 can be adjusted to a certain angle, so as to facilitate timely adjustment during the rotation of the bridge.
[0032] The side steel shell connector 4 also includes a height adjustment nut 45, which is threadedly connected to the screw rod 42, and the sliding sleeve 43 is supported by the height adjustment nut 45. The setting height of the sliding sleeve 43 can be changed by rotating the height adjustment nut 45. When the side steel shell 5 is driven by the connecting rod 44 to move horizontally to the front of the rotation adjustment seat 21, the connecting rod 44 can drive the side steel shell 5 to move upward by adjusting the setting height of the height adjustment nut 45 upward, so that the end of the side steel shell 5 is in conflict with the end of the beam, thereby fixing the side steel shell 5.
[0033] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, and all of these changes will fall within the scope of protection of the present invention.
