[0038] A protective plate 8 is fixedly connected to the rotating rod 3. An extension cavity 9 is provided in the protective plate 8. A bidirectional electric push rod 10 is installed in the extension cavity 9. Racks 11 are fixedly connected to the two telescopic ends of the bidirectional electric push rod 10. An inner rotating rod 12 is rotatably connected to the inner wall of the extension cavity 9 through a bearing. An internal gear 13 and an extrusion cam 14 are fixedly connected to the inner rotating rod 12. The internal gear 13 is meshed with the rack 11. A spring cavity 15 is connected to one side of the extension cavity 9. The spring cavity 15 is provided on the protective plate 8. A spring 16 is provided in the spring cavity 15.
[0039] The extension plate 17 is located in the extension cavity 9. The side wall of the extension plate 17 and one end of the spring cavity 15 are fixedly connected with a fixing ring 18, and the spring 16 is hooked on the fixing ring 18. When the motor 6 is started, it drives the main gear 7 to rotate, and the main gear 7 is engaged with the slave gear 4 to drive the rotating rod 3 to rotate, and the rotating rod 3 drives the protective plate 8 fixed thereon to rotate, and the flexible end of the protective plate 8 is swung out from the accommodating cavity 2.
[0040] Preferably, if Figure 1 As shown, the rotating rod 3 is fixed to one end of the slave gear 4 and extends into the transmission cavity 5. The slave gear 4 and the main gear 7 are located in the transmission cavity 5, which is convenient for internal transmission and drives the protective plate 8 to rotate.
[0041] Furthermore, if Figure 1 and Figure 3 As shown, the protective plate 8 is located in the accommodating cavity 2, which is convenient for storage and saves space.
[0042] Furthermore, if Figure 3 As shown, the extension cavity 9 passes through the bottom of the protection plate 8 , so that the extension plate 17 can extend from the lower end of the extension cavity 9 .
[0043] Furthermore, if Figure 3 As shown, a guide groove 19 is opened on the inner wall of the extension cavity 9, and a guide slider 20 is slidably connected in the guide groove 19.

In the initial state, the protective plate 8 is located in the accommodating chamber 2, and the extension plate 17 is located in the extension chamber 9. When the hydraulic support needs to protect the jack 40 during operation, the starting motor 6 drives the main gear 7 to rotate, the main gear 7 engages with the slave gear 4 to drive the rotating rod 3 to rotate, and the rotating rod 3 drives the protective plate 8 to rotate. The lower end of the protective plate 8 extends out of the accommodating chamber to protect the upper part of the jack 40, and then the bidirectional electric push rod 10 is started, and the telescopic ends on both sides of it are retracted at the same time. The two sets of racks 11 are driven to approach each other, the racks 11 are meshed with the internal gears 13, and the two sets of internal gears 13 rotate in opposite directions, so that the protruding ends of the two sets of extrusion cams 14 swing downward and move in the arc groove 21, pushing the extension plate 17 out of the extension cavity 9, and the spring 16 is stretched. The extension plate 17 is convenient for increasing the protection area and improving the side protection of the jack 40. When the work is completed and needs to be reset, the telescopic end of the two-way electric push rod 10 is started to extend, and the extension plate 17 is pulled back into the extension cavity 9 due to the elastic force of the spring 16. The motor 6 is started in reverse, and the main gear 7 cooperates with the slave gear 4 to make the rotating rod 3 retract the protective plate 8 into the accommodating cavity 2, which is convenient for storage and saves space.
