Abstract
The utility model relates to a maintenance auxiliary device for the penstock of a large-scaled electric generating set, in particular to a mobile platform for penstock maintenance, which comprises a working platform arranged inside a pressure pipeline and a support device; wherein the working platform is suspended and is connected with a No. 1 windlass through a pulley block and ropes; both ends of the working platform are provided with the support wheels contacted with the pressure pipeline wall; a pulley of the support device is positioned in a slanted straight section of the pressure pipeline and is further connected with a No. 2 windlass through a pulley block and ropes; the pulley is fixedly connected with a support rod; and the support rod is connected with the working platform. Compared with the prior art, the mobile platform has the advantages of simple structure, convenient operation, high safety, shortened penstock maintenance and anti-corrosion operation, and high working efficiency.
Description
Technical field
The utility model relates to the maintenance accessory equipment of the penstock of Generator Set, specifically a kind of penstock maintenance mobile platform.
Background technology
After the Generator Set long-term use, its penstock corrosion is serious, badly influences service life of unit and safe in utilization, needs regularly overhaul and anticorrosion maintenance penstock.But the oblique straight section drop of penstock is big, and the staff be difficult for to climb maintenance, need overheadly carry out work by what build temporarily, and physical features tilts, and the potential safety hazard that exists the high-altitude to fall causes the service work cycle long, inefficiency.
The utility model content
The technical problems to be solved in the utility model is: a kind of safety factor height is provided, and easy to operate, shorten the penstock maintenance of period of inspection and repair and use mobile platform, to overcome many deficiencies of prior art.
Realize above-mentioned purpose by the following technical solutions: mobile platform is used in a kind of penstock maintenance, comprises placing pressure pipeline in-to-in workplatform, also comprises bracing or strutting arrangement, wherein:
A, the unsettled setting of described workplatform, and be connected with a winch with rope by assembly pulley, be equipped with and the contacted support wheel of pressure pipeline wall at these workplatform two ends;
Coaster in b, the described bracing or strutting arrangement places the oblique straight section of pressure pipeline, and is connected with No. two winchs with rope by assembly pulley, is connected with strut bar on this coaster, and this strut bar is connected with workplatform.
Compared with prior art, the utility model is simple in structure, and is easy to operate, safe, can shorten the maintenance and the anticorrosive work of penstock greatly, high efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, the interior diameter of penstock 13 is 5.6 meters in the present embodiment, and tiltedly the straight section oblique angle is 80 degree, and its drop is 60 meters, and the assembly pulley in the present embodiment comprises pulley 3, No. two pulleys 5 and is loaded on fixed wheel 4 on penstock 13 inwalls.This penstock overhauls with the unsettled oblique straight section of penstock 13 in-to-ins that is arranged at of workplatform 6 levels of mobile platform, the support wheel 7 that install at its two ends and the inwall closed contact of penstock 13, and this support wheel 7 adopts rubber tires, avoids damaging tube wall.Lifting rope 14 is housed on the workplatform 6, is loaded on No. two suspension hooks 11 on the pulley 5 and hooks 14, No. two pulleys of this rope, 5 usefulness ropes 12 and be connected with fixed wheel 4 on being fixed on penstock 13 inwalls, then be loaded on penstock 13 in No. two winchs 1 be connected.
Coaster 9 in the bracing or strutting arrangement is parallel with the oblique straight section of pressure pipeline 13, and the road wheel 10 of rubber material is equipped with in these coaster 9 bottoms, and an end of this coaster 9 is fixing with rope 12, by behind pulley 3, and is connected with a winch 2 that is loaded in the penstock 13.Be welded with strut bar 8 on this coaster 9, this strut bar 8 is hinged with workplatform 6, and this workplatform 6 is played a supporting role.
Two winchs in the utility model all adopt 2 tons of winchs, have guaranteed the safety of staff when maintenance.Service personnel stands in implements maintenance on the workplatform 6, the progress along with work can realize the variation of control position by the veer and haul rope.
