The utility model content

To the above-mentioned deficiency that prior art exists, the purpose of the utility model is to provide a kind of servicing unit that lays cabling in the horizontal crane span structure laborsaving, not easy damaged cable.

To achieve these goals; The technical scheme that the utility model adopts is such: the servicing unit of cabling in horizontal crane span structure, this servicing unit comprise one be used for the roller bearing of cross-arm on crane span structure be enclosed within the roller bearing two ends be used to be stuck in the limiting plate outside the crane span structure two side.

Said roller bearing two ends are respectively equipped with radial direction through hole, have passed bolt in the radial direction through hole, and on roller bearing, two limiting plates are positioned at the bolt inboard to bolt through nut check.

The radial direction through hole of the every end of said roller bearing has 2-4, and bolt is one, in the bolt radial direction through hole located therein.

Said radial direction through hole is provided with the formation bar hole along the roller length direction.

Be respectively equipped with rubber cushion between said two limiting plates and the bolt.

The distance of said two limiting plates inboard is than the big 25-40 millimeter of distance between the outside, crane span structure two side.

Compared with prior art, the utlity model has following beneficial effect:

1. lay laborsaving.The sliding friction that became when laying originally is rolling friction, therefore can reduce construction intensity greatly, and the work of laying that needed multi agent cooperation to accomplish originally adopts this device back only to need a people to accomplish, and has both saved human cost, increases work efficiency again.

2. because frictional force reduces, and the suffered wearing and tearing of rubber skin of cable also reduce greatly, and the rubber skin can not gall, so laid processes easy damaged cable not.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Referring to Fig. 1; On scheming, can find out; The servicing unit of the utility model cabling in horizontal crane span structure, this servicing unit comprise one be used for the roller bearing 1 of cross-arm on crane span structure be enclosed within the roller bearing two ends be used to be stuck in the limiting plate 2 outside the crane span structure two side, limiting plate 2 is actual be processed as discoid.

Said roller bearing 1 two ends are respectively equipped with radial direction through hole 3, have passed bolt 4 in the radial direction through hole 3, and bolt 4 is locked on the roller bearing 1 through nut 5, and two limiting plates 2 are positioned at bolt 4 inboards, are blocked by bolt 4 and prevent that limiting plate 2 from coming off from roller bearing 1 two ends.

The radial direction through hole 3 of the every end of said roller bearing has 2-4; See Fig. 2; Bolt is one, in the bolt radial direction through hole located therein and can adjust to as required in the other through hole, thereby adjusts the spacing of two bolts; This spacing has also determined the maximum spacing of two limiting plates, thereby applicable to the crane span structure of different in width.

The radial direction through hole 3 of the every end of said roller bearing also can only be one and along the roller length direction formation bar hole is set that its purpose also is the spacing that is used to adjust two bolts, makes the crane span structure of this device applicable to different in width, sees Fig. 3.If a plurality of radial direction through hole in front are for there being level adjustment spacing, this bar hole just is equivalent to step-less adjustment so.If roller bearing intensity allows, also can the radial direction through hole at roller bearing two ends be communicated with longer bar hole of formation.
