Description
Technical field
The invention belongs to engineer operation equipment technical field, and in particular to a kind of low level installs the detachable highway of docking
Steel bridge is carried and sets up car.
Background technology
Assembly type steel bridge on highway as Ministry of Communications for official reserves one of material for preparedness against war, existing decades are wide variety of
History, no matter in the repairing of wartime highway bridge, rush construction, overcomes rivers obstacle, or in usually antidetonation, the flood-fighting disaster relief, friendship
Irreplaceable effect is all played in logical guarantee.
In assembly type steel bridge on highway erection process set up car, it is necessary to truss, crossbeam etc. are moved to carrying by manpower
On, then docked.The auxiliary erection equipment of assembly type steel bridge on highway, mainly there is two classes at present, and a class is puopulsion equipment, such as
Flat rolling, rock and roll, lower edge joint, inclined-plane chord member, another kind of is installation tool, such as spanner, crowbar, mallet, but these equipment are equal
The carrying and erection of truss and crossbeam cannot be realized.
It is existing to carry spanning equipment (car) although the carrying and erection of truss and crossbeam be carried out, it is existing
It is mostly that overall non-disconnectable, position fixes immutable to carry spanning equipment (car), and operation height can only be by whole auxiliary
The lifting of implement hydraulic oil pipe is adjusted, and equipment itself can not be adjusted, it is difficult to deliver the article of different size；Consider
Operation region is complicated and changeable, and the height of truss may be close to fork truck upper level sometimes, now will be unable to operation, it is impossible to realize
Low Low Level operation；Because shelf surface is excessive with the frictional force of truss, cause movement laborious, have impact on truss docking efficiency.
The content of the invention
The technical problem to be solved in the present invention is that：For the technical problem that prior art is present, the present invention provides one
The detachable highway steel bridge carrying erection car that low level installs docking is planted, its position-adjustable, structure are detachable, it is possible to achieve surpass
The purpose of Low-position operation.
In order to solve the above technical problems, the present invention uses following technical scheme：
The detachable highway steel bridge that a kind of low level installs docking carries erection car, including preposition lifting roll assembly, car body
