[0019] The technical scheme of the utility model will be further described below with reference to the drawings.

[0020] As shown in Figure 1 and Figure 2 The utility model provides a bearing driving device of shield door mainly by door machine beam 2 and guide rail 3, door machine beam 2 and guide rail 3 are set up in front and back, door machine beam 2, guide rail 3 are composed of multiple sections respectively, when installing, the both ends of door machine beam 2 are connected with stand 1, form support piece, support guide rail 3 and door leaf driving mechanism, guide rail 3 corresponds with left and right door leaf, has two sections, guide rail 3 is fixed on the side of door machine beam 2, supports left and right door leaf sliding.

[0021] As shown in Figure 2The gantry beam 2 comprises at least three sections: the left and right end lintel beams 201, and the middle beam 202. The lintel beams 201 and the middle beam 202 have similar structures, such as... Figure 3 , Figure 4 All components are based on rectangular tubes, with T-shaped supports at both ends. These supports include vertical end plates 2011 and 2022 and parallel support plates 2012 and 2021. End plates 2011 and 2022 are connected to the side of column 1 via screws, washers (not shown), etc. The bottoms of support plates 2012 and 2021 are bent away from the guide rail 3. Figure 5 The bottom bending parts of the support plates 2012 and 2021 can be connected to the plates on the side of the column 1 by screws to increase stability. Steel pipes are preferred for rectangular tubes.

[0022] The support height of the intermediate beam 202 is greater than the support height of the lintel beam 201. That is, the height of the end plate 2022 and support plate 2021 is greater than that of the end plate 2011 and support plate 2012. This increased height of the end plate 2022 and support plate 2021 is used to install the drive mechanism. Taking a belt drive as an example... Figure 6 The support plate 2021 at one end of the intermediate beam 202 is used to install the driven wheel, and the support plate 2023 at the other end is used to install the driving wheel and motor. The belt 6 is connected to the driven wheel and the driving wheel to make them move synchronously. The belt 6 is connected to the carrying trolley 5 through the connecting frame to drive the door leaf 7 to slide, open or close. The width of the end plates 2011 and 2022 is not less than the thickness or width of the column 1. The end plates 2011 and 2022 are connected to the side of the column 1 to ensure the overlap area with the column 1 to ensure the connection strength. At the same time, the rectangular tube can protrude a part relative to the column to facilitate the installation of the guide rail 3. The guide rail 3 is preferably made of aluminum.

[0023] like Figure 5 The guide rail 3 is L-shaped. The vertical side arm is connected to the side wall of the gantry beam 2 via washers, screws, and the horizontal side arm is connected to the top surface of the gantry beam 2 via a hanger 4. A load-bearing steel bar 301 is provided on the horizontal side arm of the guide rail 3. The load-bearing trolley 5, which is connected to the door leaf 7, rolls on the load-bearing steel bar 301, causing the door leaf to slide left and right. Reinforcing ribs are provided on the inner sides of the horizontal and vertical side arms.

[0024] During assembly, such as Figures 1 to 6 Four columns 1 are selected. The two ends of the middle beam 202 are connected to the sides of the two middle columns 1 respectively. The lintel beam 201 is located at both ends of the middle beam 202, and its legs are connected to the sides of the columns 1. The guide rail 3 is connected to the middle beam 202 and part of the lintel beam 201 through washers, screws, and hangers 4, thus completing the assembly of the load-bearing mechanism. The belt drive device is installed on the support plate 2021, and the load-bearing trolley 5 is installed on the guide rail 3. The load-bearing trolley 5 and the belt are connected by a connecting bracket (not shown), thus completing the installation of the load-bearing drive device.
