Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 and 2, a mechanical follow-up jacking door includes that the superiors imports and exports door opening 1, the fixed door frame 2 that is provided with in the superiors import and export door opening 1's top, the bilateral symmetry of door frame 2 is provided with a plurality of door guide wheels 3, door frame 2 and door guide wheel 3 fixed connection, one side that door guide wheel 3 kept away from door frame 2 is provided with door guide rail 4, door guide wheel 3 and door guide rail 4 roll connection, the below symmetry at 2 both ends of door frame is provided with door ejector pin 5, door ejector pin 5 and door frame 2 fixed connection, still including setting up the superiors import and export door opening 1 below lift operation platform 6, lift operation platform 6 and door ejector pin 5 can contact and be connected, door ejector pin 5 is used for jacking door frame 2, door guide rail 4 is used for giving door frame 2 direction.
On the basis, the weight that the door ejector rod 5 can lift is not less than twice of the weight of the door frame 2, and the door ejector rod is used for preventing the door guide rail 4 and the door guide wheel 3 from being clamped.
On the basis, a horizontal rib beam is arranged between the two door ejector rods 5 and is fixedly connected with the two door ejector rods 5 respectively, and the horizontal rib beam is used for ensuring that the horizontal positions of the two jacking rods are flush.
On the basis, the door guide rail 4 extends to the lower end of the entrance and exit door opening 1 at the uppermost layer, and the height of the door guide rail 4 is larger than the sum of the height of the door frame 2 when the door frame is opened and the height of the entrance and exit door opening 1 at the uppermost layer, so that personnel can conveniently pass through the entrance and exit door opening.
