Slip base is set to the portal-framed structure both ends, is provided with sliding slot on the slip base；
Sliding beam is slideably positioned on the slip base by the sliding slot, and the sliding beam is connected to large vehicle walking machine
Structure；
Reaction frame is translated, is set on the slip base；
Jack is translated, one end is connected to the translation reaction frame, and the other end is connected to the sliding beam；
Reaction frame is jacked, is set on the portal-framed structure；
Jack, one end are connected to the jacking reaction frame, and the other end is connected with jacking block.
Further, the first diagonal brace is provided between the slip base and portal-framed structure.
Further, the second diagonal brace is provided between jacking reaction frame and the portal-framed structure.
Further, the sliding beam is fixed on the different location of the sliding slot by the bolt of two sides.
Further, the sliding beam is completed by the movement of liter cylinder and the movement of contracting cylinder of translation jack in the sliding slot
In position adjustment.
Further, the jack does a liter cylinder movement, jacking block and ground is held out against, and overall structure is jacked one
Fixed height, so that cart walking mechanism vacantly carries out gauge adjustment afterwards, after completing gauge adjustment, the jack makees contracting cylinder
Movement makes jacking block be detached from ground, so that cart walking mechanism bears all load completely.
Further, the cart walking mechanism includes rail wheel.
The utility model proposes variable rail gauge portal crane, can by a portal crane be applied to one
Cart running track spacing can find greatly to have expanded the application range of equipment on the lifting transport road of variation, can be very
The requirement of the regional lifting transport of adaptation to the ground complexity well.
Detailed description of the invention
Fig. 1 and Fig. 2 show the portal crane structural schematic diagram of the variable rail gauge of the utility model preferred embodiment.
The jack that Fig. 3 show the utility model preferred embodiment overall structure is jacked after structural representation
Figure.
The portal crane that Fig. 4 show the utility model preferred embodiment becomes the structural schematic diagram after rail.
Fig. 5 show the sliding groove structure schematic diagram of present pre-ferred embodiments
Specific embodiment
Specific embodiment of the present utility model, but the utility model implementation not limited to the following are provided below in conjunction with attached drawing
Mode.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted that attached drawing
It is all made of very simplified form and uses non-accurate ratio, be only used for convenience, lucidly aid in illustrating the utility model
The purpose of embodiment.
Fig. 1, Fig. 2 and Fig. 5 are please referred to, Fig. 1 and Fig. 2 show the door frame of the variable rail gauge of the utility model preferred embodiment
Formula crane structure schematic diagram.Fig. 5 show the sliding groove structure schematic diagram of present pre-ferred embodiments
The utility model proposes a kind of portal cranes of variable rail gauge, including：
Portal-framed structure 6 is provided with trolley body 7；
Slip base 4 is set to 6 both ends of portal-framed structure, is provided with sliding slot 3 on the slip base 4；
Sliding beam 2 is slideably positioned on the slip base 4 by the sliding slot 3, and the sliding beam 2 is connected to big garage
Walk mechanism 1；
Reaction frame 13 is translated, is set on the slip base 4；
Jack 12 is translated, one end is connected to the translation reaction frame 13, and the other end is connected to the sliding beam 2；
Reaction frame 8 is jacked, is set on the portal-framed structure 6；
Jack 9, one end are connected to the jacking reaction frame 8, and the other end is connected with jacking block 10.
According to the utility model preferred embodiment, the first diagonal brace 5 is provided between the slip base 4 and portal-framed structure 6.Institute
It states and is provided with the second diagonal brace 11 between jacking reaction frame 8 and portal-framed structure 6.
The sliding beam 2 is fixed on the different location of the sliding slot 3 by the bolt of two sides.The sliding beam 2 passes through flat
