Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, in which preferred embodiments in the description are given by way of example only, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the scope of protection of the present utility model.
Embodiment one:
as shown in fig. 1 to 5, the present embodiment adopts the following technical scheme: it is formed by connecting 36 arc-shaped sheets 1 end to end; the height of the inner annular edge 1-1 of the arc-shaped sheet 1 is greater than that of the outer annular edge 1-2; the inner annular edge 1-1 of the arc-shaped piece 1 is provided with a plurality of bolt through holes 1-7, the polyurethane sealing piece is connected with the sealing part of the large hoisting equipment by utilizing the fixing bolt to match with the bolt through holes 1-7, wherein the top of the fixing bolt is arranged in the bolt through holes 1-7 (when the large hoisting equipment is assembled, the polyurethane sealing piece is extruded, and the part of the bolt through holes 1-7 higher than the fixing bolt provides a abdication for assembling extrusion); a butt joint groove 1-3 is formed in the surface of one end of the arc-shaped piece 1, and a butt joint clamping groove 1-4 is formed in the butt joint groove 1-3; the other end of the arc-shaped sheet 1 is outwards integrally formed with an extension sheet 1-5, the extension sheet 1-5 is matched and clamped with the butt joint groove 1-3, and the extension sheet 1-5 is adhered with the butt joint groove 1-3 by using glue; the bottom surface of the extension piece 1-5 is integrally formed with a clamping piece 1-6, the clamping piece 1-6 is clamped with the alignment clamping groove 1-4, and the alignment clamping groove 1-4 is bonded with the clamping piece 1-6 by using glue; the alignment clamping groove 1-4 and the clamping piece 1-6 are both arranged in a convex structure.
When the utility model is assembled, after two adjacent arc-shaped sheets 1 are aligned with the butt joint groove 1-3 by utilizing the extension sheet 1-5, glue is coated in the butt joint groove 1-3 and the butt joint clamping groove 1-4, finally the clamping sheet 1-6 is clamped into the butt joint clamping groove 1-4 for pressing and pasting, and 36 arc-shaped sheets 1 are fixed in an end-to-end manner according to the step, so that a circular polyurethane sealing piece is formed, and then the polyurethane sealing piece is fixed on large-scale hoisting equipment by utilizing the fixing bolt matched with the bolt perforation 1-7.
