Description
Technical field
The utility model relates to crane field, is specifically related to a kind of large span overhang crane main beam section bindiny mechanism.
Background technology
Factory building rack due to distortion, makes crane track become large, the many fulcrum suspension cranes of another electric single-beam after place in operation a period of time thereupon, for compensating the amount of deflection change that girder produces because of lift heavy, respectively all has certain camber across girder.Girder can produce downwarp when lift heavy, makes the actual length of girder in span scope slightly larger than span.Common girder connection mode is that bolt is rigidly connected, and this connection mode cannot discharge this part extra length that main beam deformation causes, thus causes sport car to produce horizontal thrust to track, causes the phenomenon run and steadily even do not gnaw rail.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of large span overhang crane main beam section bindiny mechanism, and it can make crane track distortion have and suitably discharge space, avoids the operation caused because of Main Girder Deflection change steadily even not gnaw rail phenomenon.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of large span overhang crane main beam section bindiny mechanism, comprise adjacent girder I and girder II, down suction is all left in the web of described girder I and the web abutting end top of girder II, the web of girder I and the web abutting end of girder II are respectively arranged with bindiny mechanism I and bindiny mechanism II, bindiny mechanism I and bindiny mechanism II is provided with adapter shaft, and bindiny mechanism I is connected by adapter shaft with bindiny mechanism II.
Described bindiny mechanism I comprises two connecting panels of the web both sides being fixed on girder I, two connecting panels are provided with pin-and-hole, described bindiny mechanism II comprises two locatings plate of the web both sides being fixed on girder II, connecting panel is stuck in outside locating plate, two locatings plate are provided with the perforation corresponding with pin-and-hole with on the web of girder II, and described adapter shaft is arranged in pin-and-hole and perforation.
Described girder I is provided with locating piece I on the upper cover plate of girder II one end, and girder II is provided with two positioning block II on the upper cover plate of girder I one end, and the gap between two positioning block II forms the positioning groove corresponding with locating piece I.
The utility model all leaves down suction at the web of girder I and the web abutting end top of girder II, adapter shaft couples together adjacent two sections of girders, adjacent two sections of girders can be rotated around adapter shaft, when avoiding girder generation amount of deflection to change, harmful effect is produced to the contact of sport car and track, the girder length increase caused because camber reserved by girder when ensure that girder load-bearing generation downwarp is discharged, avoid girder load-bearing downwarp and horizontal thrust is produced to sport car, effectively prevent the appearance of gnawing rail phenomenon.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of large span overhang crane main beam section bindiny mechanism, comprise adjacent girder I2 and girder II3, down suction 1 is all left on the web of girder I2 and the web abutting end top of girder II3, the web of girder I2 and the web abutting end of girder II3 are respectively arranged with bindiny mechanism I4 and bindiny mechanism II5, bindiny mechanism I4 and bindiny mechanism II5 is provided with adapter shaft 6, and bindiny mechanism I4 is connected by adapter shaft 6 with bindiny mechanism II5.Bindiny mechanism I4 comprises two connecting panels 7 of the web both sides being fixed on girder I2, two connecting panels 7 are provided with pin-and-hole 10, bindiny mechanism II5 comprises two locatings plate 11 of the web both sides being fixed on girder II3, connecting panel 7 is stuck in outside locating plate 9, the web of two locatings plate 11 and girder II3 is provided with the perforation 12 corresponding with pin-and-hole 10, and adapter shaft 6 is arranged in pin-and-hole 10 and perforation 12.Girder I2 is provided with locating piece I8 on the upper cover plate 13 of girder II3 one end, girder II3 is provided with two positioning block II 9 on the upper cover plate 14 of girder I2 one end, gap between two positioning block II 9 forms the positioning groove 15 corresponding with locating piece I8, and locating piece I8 can be stuck in positioning groove 15.
As shown in Figure 4, during the present embodiment assembling, two connecting panels 7 are stuck in the outside of locating plate 9, locating piece I8 is inserted in positioning groove 15, make pin-and-hole 10 and perforation 12 alignment, then adapter shaft 6 to be penetrated in pin-and-hole 10 and perforation 12 thus two adjacent girders are coupled together.The present embodiment adapter shaft 6 couples together adjacent two sections of girders, two sections of adjacent girders can rotate around adapter shaft 6, when avoiding girder generation amount of deflection to change, harmful effect is produced to the contact of sport car and track, down suction is all left in girder web plate top, joint, the girder length increase caused because camber reserved by girder when ensure that girder load-bearing generation downwarp is discharged, as shown in Figure 5, avoid girder load-bearing downwarp and horizontal thrust is produced to sport car, effectively prevent the appearance of gnawing rail phenomenon.Two sections of girder joint webs are provided with connecting panel and locating plate, effectively prevent two sections of adjacent girder generation end float misalignments.Joint girder upper cover plate installs locating block device additional, ensures that after two sections of girders connect, flange plate docking is accurate up and down, guarantees that cucurbit is operated steadily in joint, promote complete machine traveling comfort, prevent the generation of gnawing rail phenomenon, and be more convenient to transport and install.
