Description
Technical field
The present invention relates to a kind of structure and type of attachment of the machine Zhi Qisheng system of building bridge, relate to a kind of bridging machine for both highway and railway hoisting system structure specifically.
Background technology
Because the efficiency of construction of bridge formation machine and security reliability are high, so in global highway and railroad bridge construction, obtain using very widely.Be in the peak period in highway in China and railway construction; The beam type of speedway is very similar with the beam type of special line for passenger trains (speed per hour is below 200 kilometers), railway transportation industrial siding and common railway line simultaneously; In order to utilize equipment to greatest extent; Reduce production costs, require by the bridge formation machine that can satisfy speedway T type roof beam structure facility worker with regard to requiring a kind of erection construction that promptly can satisfy railway T type beam.For the bridge formation machine of railroad bridge construction, should satisfy the requirement of ew line construction, can satisfy the construction requirement on existing line again.
On the railway existing line, construct, at first all constructions and haulage device must satisfy the railway clearance requirement, and this just requires to build bridge and confidentially on existing line, sets a roof beam in place and just transport and must be controlled at appearance and size in certain value range.Satisfying under the prerequisite of construction requirement, reducing the height of the construction of setting a roof beam in place to greatest extent, increasing bridge formation machine height safe in utilization.So just require the many mechanism structure on the bridge formation machine compact, small and exquisite.
Summary of the invention
The object of the invention provides a kind of hoisting system structure with the bridge formation machine that can realize speedway and railway T type beam in order to solve existing weak point in the above-mentioned prior art just.
The object of the invention can be realized through following technique measures:
Bridging machine for both highway and railway hoisting system structure of the present invention comprises sitting and is placed on the vertical shift dolly of girder horn on getting on the right track; Seat is placed on the traversing trolley frame on the cross moving track of vertical shift dolly; In the rear and front end of traversing trolley frame a hoist engine is installed respectively, and described two hoist engines are arranged on the two ends of traversing trolley frame with the mode of relative side; The leading block assembly that wherein is positioned at the hoist engine next door of wire rope through being positioned at traversing trolley frame front end on the hoist engine of traversing trolley frame rear end raps around to and is set in place on the corresponding fixed pulley assembly of traversing trolley frame middle part, and the leading block assembly that is positioned at the hoist engine next door of wire rope through being positioned at traversing trolley frame rear end on the hoist engine of traversing trolley frame front end raps around to the method that is set in place the standdle carrier wire rope handling on the corresponding fixed pulley assembly of traversing trolley frame middle part again.
Why the present invention is arranged on described two hoist engines the both sides of traversing trolley frame rear and front end with side, relative mode; Its objective is satisfy under the prerequisite of himself strength and stiffness for make hoist engine when satisfying the construction of bridge formation machine with other device and mechanism's interference; So just reduce the effective height of whole hoisting system widely, made the bridge formation machine in the construction of setting a roof beam in place, can satisfy the requirement of railway clearance.
It is exactly that the wire rope that comes out of artificial increasing hoist engine is to the distance between first pulley of fixed pulley assembly that hoisting system wire rope handling form described in the present invention adopts the method for standdle carrier wire rope handling; Improve the rope stretching drift angle of wire rope with this, improve the application life of wire rope.
Basic principle of the present invention is following:
Because the bridge formation machine need be accomplished the operating mode of setting a roof beam in place, packing transportation under the requirement of satisfying railway clearance; Railway T depth of beam is certain; So just require height and the width of bridge formation machine when construction can not surpass railway clearance; Satisfy above requirement, just must reduce the appearance and size of other operating mechanism as far as possible.Adopt hoisting system of the present invention just can satisfy the instructions for use of bridge formation machine.
The traversing dolly that is configured to of hoisting system is sitting on the vertical shift dolly, and the vertical shift dolly moves on the face that gets on the right track of girder horn, can satisfy bridge formation machine vertical, horizontal of hoisting system when setting a roof beam in place and move.Hoist engine is not interfered with mechanism with other device satisfying bridge formation machine when construction, and the while is satisfying under the prerequisite of himself strength and stiffness, and its base is connected with bolt at front/rear end with traversing trolley frame.When the hoist engine lift heavy was stressed, main strength was born by traversing trolley frame, and connecting bolt bears pulling force.Through this hoist engine ground mounting means, just can be so that the whole height of hoisting system reduce to greatest extent, the railway clearance requirement when constructing to satisfy the bridge formation machine.
The present invention has following beneficial effect compared with prior art:
1) solved traditional bridge formation machine hoisting system and must be arranged in above the traversing trolley frame, so just can reduce the whole height of hoisting system to greatest extent, when constructing and transport, satisfied the railway clearance requirement to satisfy the bridge formation machine.
2) adopted the method for standdle carrier wire rope handling, just can strengthen the distance between hoist engine to the first pulley, thereby reduce the numerical value of deflection angle of rope, played and prolong a life-span of going up the silk rope.
The form of structure of bridge formation machine hoisting system of the present invention has the excellent popularization effect, not only can be applied in highway and the railway bridge erecting machine, also can be applied to widely in other crane gear.
