The portable gate assembly device of Railway Steel Truss bridge, it is characterised in that：Including rigid buttress, gate steel truss, hoist engine
And assembly platform；The rigid buttress is two groups, and along the length direction setting of bridge, along it on two groups of rigid buttresses
Length direction is equipped with two groups of movement rail：Interior mobile rail and outer mobile rail；
The gate steel truss includes horizontally disposed Steel Truss Beam and the two sub-truss posts being vertically arranged, in two supports
The lower end of truss leg is provided with least two pulleys, and the pulley of two sub-truss post lower ends and two outer mobile rail are slidably fitted in one
Rise；It is provided with along its length in the lower section of Steel Truss Beam and slides rail, the hoist engine slides rail by pulley with this is slided
It is dynamic to be combined together；The lower section of the assembly platform both sides is also respectively equipped with least two pulleys, and by being moved in pulley and two
Rail is sliding fit together；
Wherein, two corresponding pulleys of the lower end of two sub-truss posts, assembly platform corresponding two pulleys in lower section and
Hoist engine and the pulley slided between rail are driven by a motor respectively.
Further, between being provided with an equipment operation on a wherein sub-truss post of gate steel truss, in equipment operation
Between lower section be provided with cat ladder.
Further, the rigid buttress is truss structure, and the upper surface of each rigid buttress is located at same level.
Further, the thickness of the sub-truss post gradually increases from bottom to up, makes the front of sub-truss post in
Right angled triangle；Component reduces the width of the sub-truss post from bottom to up, makes the side of sub-truss post trapezoidal.
Compared with prior art, the utility model has the following advantages that：
1st, simple structure, can just lift without using Large-scale Hoisting equipment to railroad bridge, can effectively reduce and apply
Work cost.
2nd, by the cooperation of gate steel truss and hoist engine, easily railroad bridge can be lifted and is moved, spirit
Activity is good, can accurately move to specified location, and stability is high, and security is good.
3rd, operating personnel assemble on assembly platform to railroad bridge, and operation is more convenient, fast, and effect of constructing
Rate is higher, and security is also more preferable.
