Description
Technical Field
The utility model belongs to the technical field of hydraulic engineering pipeline installation construction, and particularly relates to a safe crawling ladder for large-pipe-diameter pipeline construction.
Background
In the construction of the large-diameter water conveying pipeline in China at present, constructors need to enter the pipe top to perform operations such as welding, quality inspection, joint filling, pressing test and the like, and because the pipeline is high and round, the constructors cannot directly go up to the pipe top and do up and down by means of mechanical equipment, the conventional lifting machinery is adopted to put more personnel equipment into the upper and lower pipelines, and construction interference exists in the pipeline installation and the potential safety hazard is large.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the large-pipe-diameter pipeline construction safety cat ladder which is simple in structure, convenient to operate, convenient for constructors to move on a pipeline for construction and good in safety.
The technical scheme of the utility model is as follows: a large pipe diameter pipeline construction safety cat ladder, comprising: pulley, guardrail, support frame, cat ladder, the support frame inboard is provided with a plurality of pulleys, the pulley slides along the pipeline under pressure outer wall, the support frame outside is provided with the guardrail, two fixedly connected with cat ladder between the guardrail.
Further, the guardrail includes: the safety net is arranged between the armrests and the support frame.
Further, the support frame includes: the device comprises two arc-shaped frames and an inclined truss, wherein the inclined truss is arranged between the two arc-shaped frames.
Further, a pedal is arranged on the crawling ladder.
The utility model has the beneficial effects that: according to the large-pipe-diameter pipeline construction safety ladder, the pulleys are arranged on the inner side of the supporting frame and slide along the outer wall of the pressure pipeline, so that the safety ladder can move along the pressure pipeline, and the construction efficiency is improved; the guardrails are arranged on the two sides of the cat ladder, and the safety net is arranged between the guardrails and the supporting frame, so that the risk that constructors accidentally fall from the two sides of the cat ladder can be reduced, and the safety of construction operation is improved; meanwhile, the inclined truss is arranged in the support frame, so that the whole safety ladder stand is stable in structure, and safety is further improved; in a word, the large-diameter pipeline construction safety crawling ladder is simple in structure and convenient to operate, construction staff can conveniently move on the pipeline to construct, and safety is improved.

In the figure: 1-pulley, 2-guardrail, 21-handrail, 22-pole setting, 23-safety net, 3-support frame, 31-arc frame, 32-oblique truss, 4-cat ladder, 5-footboard, 6-pressure pipeline.
Detailed Description
In the description of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; the two components can be mechanically connected, can be directly connected or can be indirectly connected through an intermediate medium, and can be communicated with each other. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
As shown in fig. 1-2, a large-diameter pipeline construction safety ladder comprises: pulley 1, guardrail 2, support frame 3, cat ladder 4, the support frame 3 inboard is provided with a plurality of pulleys 1, pulley 1 slides along pressure pipe 6 outer wall, the support frame 3 outside is provided with guardrail 2, two fixedly connected with cat ladder 4 between the guardrail 2.
Preferably, the guardrail 2 comprises: the safety net 23 is arranged between the handrail 21 and the support frame 3, one end of the vertical rod 22 is vertically and fixedly connected with the outer side of the support frame 3, the other end of the vertical rod 22 is fixedly connected with the handrail 21, and the safety net 23 is arranged between the handrail 21 and the support frame 3.
Preferably, the supporting frame 3 includes: the device comprises two arc-shaped frames 31 and inclined trusses 32, wherein the inclined trusses 32 are arranged between the two arc-shaped frames 31.
Preferably, the ladder stand 4 is provided with a pedal 5.
When the safety ladder is used, the safety ladder is hung on the pressure pipeline 6 to enable the pulley 1 to be in contact with the outer wall of the pressure pipeline 6, and when the safety ladder is required to be moved and constructed, the safety ladder is manually pushed to slide along the outer wall of the pressure pipeline 6; during the fixed construction, the worker can enter the cat ladder 4 from the gap between the bottom of the safety cat ladder and the pressure pipeline 6 and stand on the pedal 5 on the cat ladder 4 for construction.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various changes can be made therein within the knowledge of those skilled in the art.
