Description

Technical Field

[0001] The utility model belongs to the technical field of bridge support installation, in particular to a spherical cap lining device. Background Art

[0002] As an important component in the field of bridges and buildings, the spherical bearing plays the role of supporting the load of the superstructure on the one hand, and sensitively transmitting the load and deformation of the superstructure to the lower structure on the other hand. The spherical bearing usually includes an upper bearing plate connected to the superstructure, a lower bearing plate connected to the lower structure, and a spherical cap located between the upper and lower bearing plates. The spherical cap, as the main component for transmitting the load and deformation of the superstructure and the lower structure, needs to have higher wear resistance, smaller roughness and friction coefficient. In order to enable the spherical surface of the spherical cap to sensitively transmit the load and deformation of the superstructure, and at the same time have better wear resistance during the friction with the bottom surface of the upper bearing plate, three methods are generally used: welding a cladding plate on the spherical surface of the spherical cap, plating a nickel-phosphorus alloy layer on the spherical surface of the spherical cap, or using an aluminum alloy spherical cap.

[0003] Among them, the cladding plate in the method of welding the cladding plate on the spherical surface of the spherical crown needs to be pressed into a spherical shape that matches the spherical crown first, and then the pressed cladding plate is welded to the spherical crown. However, there is a requirement for the arc tolerance for the welding of the two, so as to ensure that there is a certain spherical fit between the two, so that the cladding plate can be more evenly stressed. Theoretically speaking, the cladding plate should be consistent with the curvature of the adapted spherical crown during pressing, but the curvature of the cladding plate is difficult to control, and there is usually a large tolerance, so that a certain spherical fit cannot be achieved during welding, so it is necessary to use a tooling with the same arc as the spherical crown to pressurize the cladding plate placed on the spherical crown before welding.

[0004] However, the variety of ball crown products requires different tooling for pressurization. In addition, the existing tooling is generally made of steel. During the pressurization process, the contact between the steel and the covering plate is a hard contact between steel and steel, without elasticity. Therefore, the covering plate cannot fit tightly with the ball crown and the interior is hollow, which ultimately leads to uneven force on the covering plate. Utility Model Content

[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0031] like Figure 1-2 As shown, the utility model provides a spherical crown lining device, including a spherical crown lining assembly 1, a pressurizing tool 2 and a workbench 4. When working, the spherical crown lining assembly 1 is placed on the workbench 4, and the pressurizing tool 2 applies pressure to the spherical crown lining assembly 1 above the spherical crown lining assembly 1. The spherical crown lining assembly 1 includes a covering plate 11 and a spherical crown lining plate 12, and the covering plate 11 is placed on the upper surface of the spherical crown lining plate 12. Among them, the thickness range of the covering plate 11 is: 1-3mm, the material of the covering plate 11 is stainless steel, and the material of the spherical crown lining plate 12 is cast steel or forged steel.

[0032] The pressurizing tool 2 applies pressure to the cladding plate 11 to make the cladding plate 11 and the spherical cap lining plate 12 have the same curvature, so that when the cladding plate 11 is subsequently welded to the upper surface of the spherical cap lining plate 12, a certain degree of spherical fit between the two can be ensured, so that the cladding plate 11 can be evenly stressed. In addition, the height of the weld between the cladding plate 11 and the spherical cap lining plate 12 must be within a range of 1-3 mm.

[0033] Specifically, the pressurizing tool 2 includes a pressurizing column 21, and at least six connecting blocks 22 are arranged on the bottom circumference of the side wall of the pressurizing column 21, and the number of the connecting blocks 22 is an even number. A support rod 23 is hinged on each connecting block 22, so that the support rod 23 can be freely opened and closed. A lifting belt 24 is connected between each two opposing support rods 23, and the length of the lifting belt 24 is less than the length between the end points when the two connected support rods 23 are collinear. Each lifting belt 24 passes through the top of the covering plate 11 to apply pressure to the covering plate 11. In order to ensure that the pressure applied by each lifting belt 24 to the covering plate 11 is uniform and labor-saving, the connecting blocks 22 are evenly distributed on the circumference of the pressurizing column 21, and the extension direction of the connecting blocks 22 away from the pressurizing column 21 forms an acute angle with the vertical downward direction.

[0034] The top of the pressurized column 21 is connected to a driver 3. When working, the driver 3 drives the pressurized column 21 to move up and down, driving the support rod 23 to open and close, so that the curvature of each lifting belt 24 will change with the curvature of the covering plate 11, so that the curvature of the covering plate 11 is consistent with the curvature of the spherical crown lining plate 12.

[0035] like Figure 2 As shown, during the pressurization process, the spherical crown lining 12 is placed on the workbench 4. In order to prevent the spherical crown lining 12 from sliding to the side under the action of pressure, a protrusion 41 is provided on the upper wall of the workbench 4, and a groove is provided on the lower wall of the spherical crown lining 12. The protrusion 41 is adapted to the groove. When the spherical crown lining 12 is placed on the workbench 4, the protrusion 41 is engaged with the groove to limit the spherical crown lining 12 laterally.
