Detailed Description

As shown in fig. 3 to 10, the present invention mainly includes a fixed plate 2, a limiting plate 21 and an alignment plate 22, and the following describes in detail various embodiments of the present invention with reference to the drawings.

As shown in fig. 1 and 2, for a structural schematic diagram of a lower support plate of an existing bridge support, a main body of the lower support plate is of a square structure, a spherical groove is arranged at one end of the lower support plate, a spherical bayonet 11 is arranged in the spherical groove, and four side surfaces of the lower support plate need to be milled during machining.

As shown in fig. 3 to 5, the alignment device of the first embodiment mainly includes a fixed disk 2, a limiting disk 21 and an alignment disk 22, and the fixed disk 2, the limiting disk 21 and the alignment disk 22 are all cylindrical structures and are sequentially arranged. The fixed disc 2, the limiting disc 21 and the alignment disc 22 are fixedly connected into a whole, the outer diameter of the limiting disc is the largest, the outer diameter of the alignment disc is the second, and the outer diameter of the fixed disc is the smallest. During the use, with fixed disk and milling machine bed surface fixed mounting, whole aligning device is in the horizontality this moment, and the one end that has spherical recess with the lower bearing plate is down for in the spherical bayonet was arranged in to the aligning dish, spacing dish top was arranged in to the lower bearing plate this moment. The inner diameter of the spherical bayonet is the same as the outer diameter of the alignment disc, so that the spherical bayonet and the alignment disc are concentrically arranged. In use, as shown in fig. 5, the worker grasps the lower seat plate and then rotates the lower seat plate to perform alignment.

As shown in fig. 6 to 8, a second embodiment of the present invention is different from the first embodiment in that in the second embodiment, the limiting disc includes two parts, i.e., a cover plate 212 and a bottom plate 211, which are disposed up and down, a plurality of grooves located on the same circumference are disposed in an upper surface of the bottom plate, and the circumference where the grooves are located is located outside the aligning disc. The inner wall of the groove is spherical, a through hole corresponding to the groove is arranged on the cover plate, and the inner wall of the through hole is also spherical. Alignment dish, spacing dish are processed respectively, then place ball 3 in the recess, and at this moment, half of ball is arranged in the recess, covers the apron on the chassis to realize the fixed connection between apron and the spacing dish through bolt 23, place apron top partly after the through-hole is passed on the upper portion of ball this moment. That is, the upper portion of the ball is exposed to a part of the stopper plate. The fixed disc and the base plate of the limiting disc can be manufactured integrally or manufactured respectively and then fixedly connected together.
