Description
Technical field:
The utility model relates to long distance pipeline corrosion prevention operation technical field of construction, in particular to a kind of portable bridge ladder.
Background technique:
Sino-Russian east line natural gas pipeline projects, caliber D1422mm, design pressure 12Mpa build bore in first Chinese
Greatly, the natural gas line that grade of steel is high, pressure is big.Each process construction is all a technological challenge.In corrosion-resistanting interpolating port construction, due to
Caliber is big, in addition pipe pier height, for tube top height in 2.2m, anti-corrosion work is inconvenient using common ladder in painting process, stands
There is larger security risk above pipeline.
Utility model content:
The technical problem to be solved by the present invention is to provide a kind of portable bridge ladders, and the arrangement achieves improve long defeated pipe
The safety of road anticorrosive construction worker's operation, ladder can be moved freely along pipeline, facilitated anti-corrosion work to apply priming, can be guaranteed
Anti_corrosion construction quality, the anti-decaying paint brushing of pipe top is uniform, crossline back and forth when facilitating inspection or when anticorrosive construction, production
Simple and convenient, manufacturing cost is low, and two sides ladder is detachable, convenient transportation.Overcome existing major diameter long-distance transport pipes anti-corrosion mopping
Operation is inconvenient using common ladder, and there are the deficiencies of security risk.
Technical solution adopted in the utility model is: a kind of portable bridge ladder, including ladder；It further include station, behaviour
Make platform lower end setting curved support, guardrail is set on station, curved support lower end is symmetrically arranged with multiple pulleys, curved support
Both ends pass through pin shaft respectively and are connected with two ladders, and curved support is placed in pipeline upper end, arc branch when two ladders are lifted
The pulley of support lower end can be rolled along pipeline.
Station lower end is connected on curved support by symmetrically arranged multiple support columns.
Station, curved support, ladder, guardrail are all made of steel and are made.
The beneficial effects of the utility model are: the utility model, which realizes, improves the worker's operation of long distance pipeline anticorrosive construction
Safety, ladder can be moved freely along pipeline, facilitated anti-corrosion work to apply priming, can be guaranteed anti_corrosion construction quality, pipe top
Hold anti-decaying paint brushing uniform, crossline back and forth when facilitating inspection or when anticorrosive construction, the production is simple and convenient, manufacturing cost
Low, two sides ladder is detachable, convenient transportation.
Detailed description of the invention:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of pulley.
Specific embodiment:
As shown in Figure 1 and Figure 2, a kind of portable bridge ladder, including ladder 3；It further include station 1, the setting of 1 lower end of station
Curved support 2, guardrail 4 is arranged on station 1, and 2 lower end of curved support is symmetrically arranged with multiple pulleys 5,2 both ends of curved support point
Not Tong Guo pin shaft be connected with two ladders 3, curved support 2 is placed in pipeline upper end, curved support 2 when two ladders 3 are lifted
The pulley 5 of lower end can be rolled along pipeline.
1 lower end of station is connected on curved support 2 by symmetrically arranged multiple support columns.
Station 1, curved support 2, ladder 3, guardrail 4 are all made of steel and are made.
In use, worker is sitting on station 1, it can be easily to mopping anti-corrosion at the top of pipe, when also facilitating inspection
Or crossline, construction operation are convenient and safe back and forth when anticorrosive construction.The ladder 3 at both ends is lifted after the completion of mopping at one,
Portable bridge ladder is pushed, pulley 5 runs to the place that be painted along pipeline, puts down both ends ladder 3 again.When not needing mopping
And when needing to pack up portable bridge ladder, the pin shaft on both ends ladder 3 can be unloaded, bridge ladder can be packed up at this time.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
