Detailed Description
For convenience of description, the direction along the bridge will be defined as the longitudinal direction, the direction perpendicular to the longitudinal direction in the water surface is the transverse direction, and the longitudinal direction is the front-rear direction, and the transverse direction is the left-right direction.
Example 1
As shown in fig. 4, 5, 7 and 9, a flexible suspension structure applied to the movable mold frame rear suspension beam 25 includes a longitudinal suspension frame 252, a lateral suspension frame 254 and a hooking mechanism 256.
As shown in fig. 9, the left and right sides of the lower bottom surface of the traversing base 251 are respectively provided with a first ear plate 2511 extending downward, and the vertical lifting frame 252 is disposed between the two first ear plates 2511 and is rotatably connected with the first ear plates 2511 through a first hinge shaft 253. As shown in fig. 7, the front and rear ends of the vertical lifting frame 252 are respectively provided with a transverse lifting frame 254 vertically arranged with the vertical lifting frame 252, and the transverse lifting frame 254 is rotatably connected with the vertical lifting frame 252 through a second hinge shaft 255. As shown in fig. 5, the left and right ends of each of the lateral hanging frames 254 are respectively provided with a hooking mechanism 256 for supporting the main beam 21.
As shown in fig. 6 and 8, the hooking mechanism 256 includes hooking risers 2561 respectively disposed at the left and right ends of the transverse lifting frame 254, a supporting roller 2563 for supporting the main beam 21 is disposed at the lower portion of the hooking riser 2561, and the cover 212 of the main beam 21 is pressed against the supporting roller 2563.
Further, on one hand, the cover plate 212 of the main beam 21 of the movable die carrier is often uneven, and on the other hand, a certain deflection is inevitably caused due to the large span of the main beam 21. Therefore, the hooking riser 2561 of the hooking mechanism 256 is fixedly connected to the transverse hanger 254, so that a portion of the supporting roller 2563 may not contact the cover plate 212 of the main beam 21 during use. The number of the support rollers 2563 actually used for supporting the main beam 21 is reduced, so that part of the support rollers 2563 are stressed and even deformed. For this purpose, as shown in fig. 6 and 8, the upper end of the hooking riser 2561 is rotatably connected to the lateral hanger 254 through a third hinge shaft 2562.
Further, in order to make the structure of the hooking mechanism 256 more problematic, two supporting rollers 2563 are disposed at the lower end of the hooking riser 2561, and the two supporting rollers 2563 and the third hinge shaft 2562 are arranged in an isosceles triangle, and the distances from the third hinge shaft 2562 to the two supporting rollers 2563 are equal. Preferably, the hooking riser 2561 is triangular in shape.
Further, in order to avoid the main beam 21 being offset in the left-right direction, the supporting roller 2563 on either one of the left and right sides is deformed due to excessive stress. As shown in fig. 6 and 8, two second lugs 2564 are respectively disposed on the front and rear sides of the hooking riser 2561, a guide wheel 2565 is disposed between the two second lugs 2564 on the same side, and the axis of the guide wheel is perpendicular to the axis of the supporting roller 2563. The guide wheels 2565 abut against the side surfaces of the cover plate 212 of the main beam 21, so that the main beam 21 is limited between the guide wheels 2565 on the left and right sides.
Further, as shown in fig. 7, limiting plates 211 are respectively disposed at the front and rear ends of the flexible hook structure on the main beam 21, so that the rear hanging beam 25 and the main beam 21 can move relatively within a certain range.
Further, in order to increase the rigidity of the vertical lifting frame 252, the second hinge shaft 255 penetrates the vertical lifting frame 252 in the vertical direction, and the front and rear ends of the second hinge shaft 255 are respectively provided with a mechanism for limiting the vertical movement of the horizontal lifting frame 254.
Further, in order to increase the rigidity of the entire flexible suspension structure, as shown in fig. 9, the second hinge shaft 255 is located above the first hinge shaft 253. Since the longitudinal hanger 252 is welded from sheet metal, it is relatively thin-walled, especially at the hinge holes. If the second hinge shaft 255 is disposed below the first hinge shaft 253, the second hinge shaft 255 applies a downward force to the vertical lifting frame 252, the first hinge shaft 253 applies an upward force to the vertical lifting frame 252, and only the vertical lifting frame 252 is disposed above the first hinge shaft 253 and below the second hinge shaft 255, which is easy to deform and even affects the stability of the entire moving mold frame. In the invention, the second hinge shaft 255 is positioned above the first hinge shaft 253, so that even if the longitudinal lifting frame 252 is deformed, the first hinge shaft 253 and the second hinge shaft 255 are contacted, normal use is not affected, the first hinge shaft 253 and the second hinge shaft 255 are mutually matched, and the rigidity of the flexible suspension structure is improved.
The working principle of the invention is as follows: the traversing base 251 is connected with the longitudinal lifting frame 252 through the first hinge shaft 253, so that the movable die frame main beam 21 can relatively rotate around the first hinge shaft 253, and a larger local longitudinal bending moment generated between the main beam 21 and the rear lifting beam 25 due to the change of the longitudinal slope of the bridge is released.
The longitudinal lifting frame 252 and the transverse lifting frame 254 are connected through the second hinge shaft 255, so that the movable die frame main beam 21) can relatively rotate around the second hinge shaft 255, the larger local transverse bending moment at the joint of the movable die frame rear lifting beam 25 and the movable die frame main beam 21 is released, and the phenomenon of local bending stress concentration caused by the fact that the gravity center of the movable die frame main beam 21 and accessories thereof deviate from the center of the suspension structure towards the inner side direction of the bridge is avoided.
The left end and the right end of the transverse hoisting frame 254 are provided with the hooking mechanisms 256, so that the main beam 21 can move back and forth relative to the hooking mechanisms 256, thereby avoiding larger bending moment load generated at the joint of the rear hanging beam 25 and the main beam 21 caused by asynchronous pushing of the rear hanging beam longitudinal moving oil cylinder 26 and the trolley longitudinal moving oil cylinder 27, reducing the design strength of each related structure, improving the construction safety, being beneficial to improving the construction efficiency and reducing the maintenance cost of equipment.
