Detailed Description
1. Basic structure and mounting arrangement
As shown in fig. 1 to 5, the novel micro-lifting herringbone door easy-to-detach bottom pivot mainly comprises a base 5, a base plate 6, a mushroom head 8, a ball tile 9, a top cover 10 and a pad seat 7. The base and the backing plate are of matched semicircular wall structures, the backing plate is placed on the base, and the base and the backing plate are combined to form an opening circular wall; the pad seat is of a bench type structure with two large ends and a small middle part, the pad seat is placed in an opening circular wall formed by the base and the base plate, the bottom of the mushroom head is placed on the pad seat and fixed by the base and the base plate, the ball head of the mushroom head is matched with the spherical pair between the ball head and the ball tile, and the ball tile is nested in the top cover.
As shown in fig. 1, the single-leaf gate is integrally arranged during micro-jacking, and comprises a single-leaf gate leaf structure 1, a top pivot 2, a bottom embedded plate 3 and a gate wall embedded plate 4. The top cover is fixed with the door leaf bottom main beam 11 through a hinging bolt, the ball tile is tightly connected with the top cover through a set screw 21, and the sealing ring 17 is compacted by using the sealing cover plate 12 after being installed. The disc seat of the mushroom head is just placed above the pad seat and is clamped and fixed by the base and the pad plate together. The base is connected with the backing plate through a hinging bolt. The base is buried in the secondary concrete after being adjusted in place by the vertical adjusting screw 13 and the lateral adjusting screw 15. An annular groove is formed in one side of the top cover, which is close to the pillow 18, and a special-shaped rubber 19 is arranged in the annular groove through a countersunk head screw. The top cap is close to the door leaf end girder one side is provided with special-shaped support plate, and its special-shaped support plate's part links to each other with door leaf end girder stagnant water fagging 20.
2. Disassembly process
Firstly, the single door leaf structure is opened to a fixed angle, and is ensured to be positioned above the bottom embedded plate. 4 jacks 23 (2 are respectively arranged on each bottom embedded plate) are used for slightly jacking the door leaf structure to a loose state, temporary measures (such as welding a temporary lifting lug on the door wall embedded plate to connect a steel wire rope to tighten a gate or welding steel bars to tightly prop the gate with a steel tube) are adopted for fixing the single-leaf door leaf structure. Then, removing the cover plate, connecting a temporary opening and closing device to remove the base plate after installing the eye screw on the base plate, and automatically falling off the base seat and the mushroom head at the moment; removing the pad seat by using a flying screw connected with the pad seat by using temporary opening and closing equipment, and enabling the mushroom head to fall on the base at the moment so as to be completely separated from the ball tile; after the mushroom head is removed, the set screw between the ball tile and the top cover is dismounted, then the ball tile is dismounted, and finally the top cover is dismounted, so that the bottom pivot can be completely dismounted by only slightly lifting the door leaf mechanism under the condition that the top pivot is not dismounted.
In summary, compared with the traditional herringbone door bottom pivot, the bottom pivot base and the base plate are separately designed into a semicircular wall type structure, so that the clamping of the mushroom head disc seat and the bench type base plate seat is ensured, the horizontal force in the opening and closing process of the gate is effectively transmitted, and the base plate seat are easy to detach, so that the mushroom head automatically drops off in the micro-lifting state of the gate, the overhaul cost of the gate is reduced, the overhaul period of the bottom pivot is shortened, and the safety and reliability of the dismounting of the bottom pivot are improved.
