The utility model object realizes and being completed by following technical scheme:
A kind of mobile operation platform for construction operation outside Bridge guardrail, comprise the moving body with castor, it is characterized in that being provided with main body rack on described moving body, be fixed with to the horizontal cantilever of a side extension at described main body rack top, the extension end of described horizontal cantilever is connected with adjustable for height cage, wherein, on the cantilever between described cage and described main body rack, be fixed with a fixed pulley, on described fixed pulley, be equipped with lifting rope, one end of described lifting rope is connected with described cage, and the other end is connected with described main body rack.
On described moving body, be provided with counterweight sandbag.
The height of described main body rack is not less than described guardrail height and described sling height sum.
Described cantilever is telescopic boom.
Described cage is flexibly connected with described cantilever through vertical steel pipe.
Between described main body rack and the epitaxial part of described cantilever, be provided with diagonal brace, the two ends of described diagonal brace are welded and fixed with described main body rack and described cantilever respectively.
The utility model has the advantages that, mobile operation platform can move along bridge floor easily, simple in structure, easy to assembly, sling height is adjustable, strong adaptability, be convenient to carrying and keeping, structure is segmented to be combined, and has not only ensured constructor's safety but also improved operating efficiency.
Brief description of the drawings
Fig. 1 is mobile operation platform structural representation in the utility model.
Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1, in figure, mark 1-9 is respectively: castor 1, moving body 2, main body rack 3, cantilever 4, diagonal brace 5, fixed pulley 6, lifting rope 7, vertical steel pipe 8, cage 9.
Embodiment: the present embodiment is specifically related to a kind of mobile operation platform for construction operation outside Bridge guardrail, is intended to solve not removing bridge both sides more than 2 meters in high guardrail, the construction operation that can allow again constructor's safe ready outside Bridge guardrail.
As shown in Figure 1, this moves operation platform and is made up of moving body 2, main body rack 3, cantilever 4 and cage 9.
As shown in Figure 1, moving body 2 is welded by angle steel, and its below is provided with four castors 1, castor 1 is specially universal wheel, can make moving body 2 along any direction traveling, stable in order to ensure constructor's safety and car body, on moving body 2, be provided with counterweight sandbag;
Main body rack 3 is installed on moving body 2, and main body rack 3 is specifically welded by coating steel pipe, and its height should be greater than the height sum of guardrail and cage 9;
Top ends at main body rack 3 is laterally fixed with cantilever 4, and cantilever 4 is welded by coating steel pipe equally, and a part for cantilever 4 is fixedly connected with main body rack 3, and another part extends laterally, and its outside elongated end is used for being flexibly connected cage 9; Wherein, a certain section on cantilever 4 adopts telescopic sleeve pipe syndeton, can adjust according to actual conditions the perimetric length of cantilever 4, between adjustment rear sleeve and sleeve pipe, fixes by bolt tightening; In addition, in order to promote the anti-bending strength of cantilever 4, between cantilever 4 and main body rack 3, diagonal brace 5 is set, the two ends of diagonal brace 5 are welded and fixed with cantilever 4 and main body rack 3 respectively;
Be provided with two vertical steel pipes 8 at the outside of cantilever 4 elongated end, the upper end of vertical steel pipe 8 is flexibly connected with cantilever 4, its lower end is fixedly connected with cage 9, in order to make cage 9 highly adjustable, on the cantilever 4 between cage 9 and main body rack 3, be fixedly installed a fixed pulley 6, on fixed pulley 6, wear lifting rope 7 simultaneously, one end of lifting rope 7 is fixedly connected with main body rack 3, the other end is fixedly connected with cage 9, and constructor is by pulling lifting rope 7 on main body rack 3 can regulate the height of cage 9 in the vertical directions.
As shown in Figure 1, the method for utilizing the mobile operation platform in the present embodiment to carry out construction operation in Bridge guardrail outside is as follows:
First by pulling lifting rope 7 on fixed pulley 6 to regulate the height of cage 9, this height be according to constructor at the height of Bridge guardrail outside construction and fixed, highly after adjusting, one end of lifting rope 7 is fixed with main body rack 3 colligations; On moving body 2, place afterwards counterweight sandbag, the weight of sandbag will ensure constructor's moving body 2 not run-off the straights in the time holding construction material and instrument properly and stand in 9 li of constructions of cage, safety factor in order to ensure that constructor's safety doubles in the present embodiment is placed the counterweight sandbag of 500 kilograms on moving body 2; After preparation is carried out, constructor stands in cage 9, and other auxiliary constructions personnel shift moving body 2 to need the place of construction to carry out construction operation onto from end of the bridge, in guardrail outside, the two electrical networks of foreign body intrusion monitoring or other device is installed; After construction operation, auxiliary construction personnel can be pushed into moving body 2 bridge tail relief constructor and climb out of from cage 9, also can be at the medium position place of bridge, by pulling the above lifting cage 9 of lifting rope 7 on fixed pulley 6, when after the height of cage 9 height higher than guardrail, inwardly promote moving body 2 cage 9 is positioned on bridge floor, finally transfer cage 9, constructor climbs out of from cage 9.
The beneficial effect of the present embodiment is, can be in the situation that not removing bridge guardrails of both sides, the construction operation that allows constructor's safe ready outside Bridge guardrail, be that constructor may stand in the cage of mobile operation platform and constructs, need not remove guardrail, below moving body, there are four universal caster wheels, can conveniently move along bridge floor, simple in structure, easy to assembly, sling height is adjustable, strong adaptability, be convenient to carrying and keeping, structure is segmented to be combined, and has not only ensured constructor's safety but also improved operating efficiency.
