The forward and backward guide rail being parallel to each other, forward and backward guide rail and beam vertical, are respectively provided with forward and backward guide rail
There is forward and backward end carriage, be movably set with supporting box, the top of supporting box on forward and backward end carriage respectively
It is provided with the groove position for installing girder；
Be provided with the top of the girder stand to bolt and upper and lower adjusting nut, one end of bolt is worn
The base plate of supporting box is crossed, upper and lower adjusting nut is divided into the upper and lower of supporting box base plate, led to
Upper and lower adjusting nut is overregulated, high high adjustment is realized；
The two ends of the end carriage are respectively arranged with roller group corresponding with guide rail；It is provided with the top of girder
Trolley frame.
The two ends of the end carriage are respectively arranged with the axis hole for installing roller group, and the sidepiece of the axis hole is provided with
Opening, is provided with cover plate on opening.
Further illustrating as such scheme, the trolley frame includes both sides walker and is connected to two
Support connecting frame between the walker of side, is provided with groove corresponding with both sides walker at the top of girder
Rail.
Further, the walker includes front and back ends walking beam, and support connecting frame includes being connected to
Plug into bar and the connection bridge that is connected between the walking beam of both sides between front and back ends walking beam.
The girder is box beam, and the sidepiece of girder is provided with a plurality of reinforcement for arranging from top to bottom.
This utility model is using the above-mentioned technical solution beneficial effect to be reached：
This utility model is adopted distinguishes activity setting supporting box on forward and backward end carriage, and girder is fixed on
On supporting box, the high and low position of supporting box is adjustable, it is ensured that the accuracy of crane span, makes two
The difference of the diagonal of end carriage, the horizontal difference of height of wheel reaches acceptance criteria, reduce it is more it is artificial because
Element.
