Description

Umbrella type maintenance platform

Technical Field

The utility model provides an overhaul platform, especially an umbrella formula overhaul platform belongs to generating set maintenance of equipment design and manufacturing technical field.

Background

When overhauling work such as oil baffle and cooler is carried out on a lower guide bearing of the water turbine generator set, an operator usually stands on a coupling protective cover of the water turbine generator set to work. Because hydroelectric set's shaft coupling safety cover area is less, the operation personnel have to build the scaffold in addition and just can develop work, and not only inefficiency, frequent scaffold dismouting also greatly increased work burden and cost input in addition, and in addition, narrow and small operating space also builds for the scaffold and increases the degree of difficulty, prolongs maintenance duration, has the scaffold unstability, causes the incident easily. There is therefore a need for improvements in the prior art.

Disclosure of Invention

For solving current generating set and developing the maintenance during operation, can only stand work on hydraulic generator shaft coupling protective cover with the help of the scaffold frame, and then bring the scaffold frame and build inconvenience, have safety risk, with high costs scheduling problem, the utility model provides an umbrella type overhauls platform.

The utility model discloses a following technical scheme accomplishes: the umbrella type maintenance platform comprises an umbrella type frame matched and connected with a coupling protective cover of a hydraulic generator, and is characterized in that the umbrella type frame comprises a plurality of I-shaped bottom beams in an umbrella-shaped layout, fan-shaped table plates arranged between every two I-shaped bottom beams, an annular working platform with the surrounding surfaces of the fan-shaped table plates, and a guardrail consisting of stand columns and horizontal cross rods is arranged at the outer edge of the annular working platform.

The outer end of the I-shaped bottom beam is connected with at least one pipe sleeve, corresponding upright posts are inserted into the pipe sleeves, horizontal cross rods are arranged at the upper part and the middle part between every two upright posts, and baffles are arranged at the bottom, so that a guardrail is formed, the safety of operating personnel is guaranteed, and meanwhile, the falling of a hand tool is prevented.

The fan-shaped bedplate is fixed on the I-shaped bottom beam through a first bolt and a nut.

The inner ends of a plurality of I-shaped bottom beams in the umbrella-shaped layout are fixed in screw holes corresponding to the hydraulic generator coupling protective cover through second bolts and nuts.

At least one fan-shaped bedplate is arranged between every two I-shaped bottom beams.

The utility model has the advantages and effects of: by adopting the scheme, a safe and reliable umbrella type maintenance platform can be conveniently built on the hydro-generator coupling protective cover through a rapid tower, the building and dismounting difficulty is greatly reduced, the building and dismounting efficiency is improved, and therefore manpower and material resources are saved. In addition, the annular workbench formed by the fan-shaped tables is convenient for workers to stand and place tools and equipment, and the fan-shaped tables which are spliced with one another can avoid safety accidents caused by falling objects due to gaps. The method is an ideal maintenance platform.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, the umbrella type maintenance platform provided by the present invention comprises an umbrella type frame matched with a hydro-generator coupling protective cover 10, wherein the umbrella type frame comprises eleven i-shaped bottom beams 4 in an umbrella-shaped layout, two fan-shaped bedplate 1 arranged between every two i-shaped bottom beams 4, an annular working platform is enclosed by twenty-two fan-shaped bedplate 1, and the outer edge of the annular working platform is provided with a guardrail composed of a vertical column 3 and a horizontal cross bar 2; the outer end of the I-shaped bottom beam 4 is connected with two pipe sleeves 6, corresponding stand columns 3 are inserted in each pipe sleeve 6, the upper ends of the two stand columns 3 are fixed through iron wires or conventional clamping buckles 7, horizontal cross rods 2 are arranged on the upper portion and the middle portion between every two stand columns 3, and a baffle plate 8 is arranged at the bottom of each stand column, so that a guardrail is formed, the safety of operating personnel is guaranteed, and meanwhile, the falling of a hand tool is prevented. The fan-shaped bedplate is fixed on the I-shaped bottom beam through a first bolt and a nut 5. The inner ends of a plurality of I-shaped bottom beams 4 in the umbrella-shaped layout are fixed in screw holes corresponding to the hydraulic generator coupling protective cover through second bolts and nuts 9.

When the umbrella-type maintenance platform works, after the inner ends of eleven I-shaped bottom beams 4 are in threaded connection with corresponding threaded holes in a hydraulic generator coupling protective cover 10 through second bolts and nuts 9, twenty-two corresponding fan-shaped table plates 1 can be laid on the eleven I-shaped bottom beams 4 in an umbrella-type layout and fixed through first bolts and nuts 5 to form an annular working platform, stand columns 3 are inserted into pipe sleeves 6 at the outer ends of the annular working platform, namely the I-shaped bottom beams 4, and then the upper horizontal cross rods 2, the middle horizontal cross rods 2 and the lower vertical baffle plates 8 are connected to form a guardrail, so that the umbrella-type maintenance platform is formed, as shown in fig. 1, and therefore a safe and reliable umbrella-type maintenance platform can be quickly built in a narrow operation space, manpower and material resources are saved, the building work efficiency is improved, and the safe operation is guaranteed.
