[0037] The support cylinder 300 is arranged above the ball head base 100 and is used to connect with structures such as tide sluice or bridge. The support cylinder 300 is a hollow cylinder structure and is made of steel. A plurality of arc-shaped rib plates 310 are uniformly and spacedly arranged on the inner cylinder surface of the support cylinder 300.

When the ball head bearing 400 is arranged in the bearing pressure cover 500, the limiting protrusions 410 of the ball head bearing 400 are correspondingly clamped into the bearing limiting grooves 520 of the bearing pressure cover 500.
[0042] The ball head bearing 400 is made of steel and is provided with a semispherical groove 420 at the end surface facing the ball head 200. The semispherical groove 420 of the ball head bearing 400 is matched with the semispherical surface of the ball head 200. High polymer lubricating material is arranged between the semispherical groove 420 of the ball head bearing 400 and the semispherical surface of the ball head 200, so as to ensure the rotation stability between the ball head 200 and the ball head bearing 400.
[0043] The assembly relationship of the ball hinge structure convenient to disassemble and assemble is as follows:
[0044] 1. The ball head 200 is installed on the ball head base 100, a plurality of ball head limiting protrusions 211 of the annular ball head seat 210 of the ball head 200 are matched with the ball head limiting recesses 111 of the ball head base 100, and the rotation of the ball head 200 around the horizontal direction of the ball head base 100 is limited;
[0045] 2. The ball head bearing 400 is installed inside the bearing gland 500, the outer contour of the ball head bearing 400 is matched with the internal space of the bearing gland 500, and a plurality of limiting protrusions 410 of the ball head bearing 400 are matched with a plurality of bearing limiting recesses 520 of the bearing gland 500, so that the rotation of the ball head bearing 400 around the horizontal direction of the bearing gland 500 is limited. The internal space of the ball head bearing 400 is matched with the ball head 200, and a high polymer lubricating material is arranged on the contact surface between the ball head bearing 400 and the ball head 200, so as to improve the rotation stability between the two;
[0046] 3. The supporting cylinder 300 is fixedly connected with the tide gate or bridge structure to form an integral whole, a plurality of vertical partitions 510 of the bearing gland 500 can be matched with a plurality of supporting cylinder notches 320 of the supporting cylinder 300, so that the rotation of the bearing gland 500 around the horizontal direction of the supporting cylinder 300 is limited. After the cylindrical top cover at the top of the bearing gland 500 is in contact with a plurality of arc-shaped rib plates 310 of the supporting cylinder 300, a plurality of limiting pins 600 are inserted into a plurality of pin through holes 330 arranged on the upper part of the outer wall of the supporting cylinder 300. Under the self-weight of the supporting cylinder 300 and the tide gate or bridge structure connected with the supporting cylinder 300, the limiting pins 600 are self-locked, so as to ensure the close connection between the supporting cylinder 300 and the bearing gland 500. The limiting pin 600 is composed of upper and lower limiting wedge-shaped blocks 610 and 620 which are stacked in upper and lower layers. The slope of the wedge surface of the upper and lower limiting wedge-shaped blocks 610 and 620 is small, and the self-locking is realized through the friction under the self-weight of the supporting cylinder 300 and the tide gate or bridge structure.
[0047] In the running state of the utility model, the supporting cylinder 300 is fixedly connected with the tide gate or bridge structure to form an integral whole, so that the structure rotating process will drive the supporting cylinder 300 to rotate. The horizontal rotation is limited between the supporting cylinder 300 and the bearing gland 500, and between the bearing gland 500 and the ball head bearing 400 through concave-convex structures, and the vertical movement is limited through the limiting pin 600. Therefore, when the tide gate or bridge structure rotates, the supporting cylinder 300, the bearing gland 500 and the ball head bearing 400 will be driven to rotate around the ball head 200 to realize the horizontal rotation and / or the vertical rotation.
[0048] When it is necessary to overhaul, the supporting cylinder 300 is jacked up (fixed with a tide gate or a bridge), the limiting pin 600 is removed, then the bearing gland 500 and the ball head bearing 400 are hoisted out in sequence, each part can be overhauled, the high polymer lubricating material between the ball head bearing 400 and the ball head 200 is replaced, and after the overhaul is completed, the ball head bearing 400, the bearing gland 500, the limiting pin 600 and the like are loaded in sequence. The utility model does not need to disassemble a screw during the whole overhauling and installing process, and the overhauling and installing are convenient.
