The specific embodiment
Below in conjunction with accompanying drawing a kind of elevated bell structure that the utility model provided is further explained.
The concrete connected mode of a kind of elevated bell structure that the utility model provided is following:
As shown in Figure 2, weldering circle 3 (structure is as shown in Figure 3) are welded in bell 1 inboard, and pull bar 4 penetrates bell 1 inboard from bell 1 upper end perforate 10; Gap between said pull bar 4 and the perforate 10 is 1/10 of pull bar 4 external diameters; Concave arc body 5 (structure is as shown in Figure 5) is socketed on pull bar 4 outsides, and ring diameters are greater than 1/10 of pull bar 4 external diameters in the said concave arc body 5, and said concave arc body 5 and weldering are enclosed 3 and be connected through bolt; Said concave arc body 5 peripheral connecting hole reference circles equate with weldering circle 3 connecting hole reference circles; Said concave arc body 5 cambered surfaces one end is connected with convex arc body 6 (structure is as shown in Figure 6), and said concave arc body 5 bottom concave arc surfaces and convex arc body 6 top convex faces coincide, and said convex arc body 6 is socketed on pull bar 4 outsides; Concave arc body 5 becomes the sphere sliding mode with two cambered surfaces of convex arc body 6; The internal orifice dimension of convex arc body 6 is matched in clearance with pull bar 4 or excessively cooperates that said pull bar 4 is provided with groove 9 (structure is as shown in Figure 4) with perforate 10 relative end ends, and the planar ends of convex arc body 6 is equal with the groove 9 end slot edge of pull bar 4; Said groove 9 places are connected with half clamp ring 7 (structure is as shown in Figure 7); Half clamp ring, 7 height equate highly that with the groove 9 of pull bar 4 said pull bar 4 lower ending opening inboards are provided with ring 8 (as shown in Figure 8) of rising, cover and pull bar 4 inboard and groove welding in said ring 8 matched in clearance that rise.
