The oblique column connection in lower end of support I, connected mode is bolt；
Cable hoist is installed on the inclined column in inner upright mounting one end；
Described crane girder one end is fixed on the upper longeron II of outer mast, and middle part is fixed on the upper longeron I of inner upright mounting, separately
One end is cantilever；
Electric block is arranged on crane girder, can be walked up and down along crane girder.
Inner upright mounting, outer mast are linked to be an entirety by connection beam group.
Further, the connected mode between upper longeron II, a pair oblique columns and diagonal brace I is bolt.
Further, the connected mode between the column of lower longeron, upper longeron I and a pair of opposite tilts is bolt.
Further, the lower end of inner upright mounting and outer mast is provided with travelling wheel.
Further, connection beam group includes 2 sills, 2 entablatures, 4 diagonal braces II.
Further, counterweight is located on lower longeron.
Further, rain cover partially or fully going along with sb. to guard him the top surface of whole shield straddle truck and side.
Further, rain cover is made up of color steel tile, battenboard or sunlight tile.
Further, counterweight bearing and anchor ear are installed on the lower longeron of inner upright mounting.
Further, travelling wheel is directly supported on ground using deep groove ball bearing.
The beneficial effects of the utility model are：
The utility model for it is a kind of with it is mobile, can lift by crane shield, do not influence the other procedures of bridge floor and into
Originally, the jib crane of the high effect of low effect.

Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of special cantilever simple crane of high-speed railway shield, it includes：Inner upright mounting 1, outer mast 2, crane girder 3, contact
Beam group 4, rain cover 5, counterweight 6, travelling wheel 7, cable hoist 8 and electric block 9.
The inner upright mounting is made up of the column 13 of lower longeron 11, upper longeron I 12 and a pair of opposite tilt certain angles, section
It is to use I-steel, connected mode is bolt.
The outer mast is made up of upper longeron II 21, a pair oblique columns 22 and diagonal brace I 23, section be using I-steel,
Connected mode is bolt；The distance between inside and outside door frame meets the distance between bridge floor protecting wall and straight wall, and leaves certain
Gap, prevent the collision protection wall during traveling of travelling wheel 7.
The bottom of inside and outside door frame is provided with travelling wheel 7.
Counterweight bearing and anchor ear are installed, counterweight 6 uses sound barrier shield under inner upright mounting on longeron.The one end of inner upright mounting 1 it is oblique
Finished cable capstan winch 8 is installed on column.
Two Pin door frames are linked to be an entirety by connection beam group.
Connection beam group includes 2 diagonal braces II 43 of entablature 41,4 of sill 42,2；Height of the sill 42 apart from ground
