Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of air-to-air coolers, and more specifically to an overhaul platform applicable to the coolers of synchronous condensers. Background Art

[0002] In reality, there is usually no special overhaul platform designed for the high air-to-air coolers used on synchronous condensers. It is only composed of a simple ladder and a bracket or directly uses a scaffolding. Maintenance personnel directly stand above the air cooler pedestal for daily basic maintenance and repair. Due to the insufficient design of the safety guardrail and the difficulty in fixing the scaffolding, this method is insufficient in terms of the convenience of maintenance and the personal safety of maintenance personnel, and the installation is not convenient enough. There is an urgent need for an overhaul platform that can ensure the safety of maintenance workers to repair the air cooler. Summary of the Utility Model

[0003] In order to overcome the defects existing in the above-mentioned prior art, the purpose of the utility model is to provide an overhaul platform applicable to the coolers of synchronous condensers, which has the advantages of fast installation, good stability and high safety factor.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] An overhaul platform applicable to the coolers of synchronous condensers, characterized in that: it includes a platform, brackets and a ladder. The platform is provided with a guardrail platform and has a notch. On the other side of the notch, there are mating holes. The ladder is arranged on the adjacent side of the notch; the brackets are fixedly arranged at both ends on the same side of the platform. There are two brackets, and a cross beam is arranged between the brackets. There are mounting holes on the cross beam; adjusting components are arranged at the bottom of the brackets.

[0006] Preferably, the adjusting component includes a movable bracket and a screw. The movable bracket can freely expand and contract along the height direction of the bracket, and a number of through holes for cooperating with the screw are equidistantly arranged on the movable bracket.

[0007] Preferably, the adjustment range of the adjusting component is 0-10 mm.

[0008] Preferably, the cross section of the bracket is rectangular or circular.

[0009] Preferably, an auxiliary inclined support is arranged at the connection end of the cross beam and the bracket.

[0010] Preferably, the surface of the platform is provided with anti-slip lines.

[0011] Preferably, an auxiliary ladder is arranged inside the notch.

[0012] Preferably, the ladder and the auxiliary ladder are provided with guardrails.

[0013] Preferably, the ladder is provided with a safety platform.

[0014] Preferably, the materials of the platform, the support and the escalator are all made of alloy steel.

[0015] Advantages of the utility model:

[0016] 1. Compared with the prior art, a maintenance platform is provided, which has a high degree of fit and a small gap with the air cooler, facilitating maintenance personnel to repair the fan of the air cooler. The platform and the escalator are provided with guardrails, ensuring the personal safety of the maintenance personnel. By bolting the cross beam to the lower end of the outer seat and bolting the other side of the platform notch to the air cooler body, the entire maintenance platform makes the best use of the outer seat of the air cooler as a support, enhancing stability and having a high safety factor. Through prefabricated modular standard design, the installation is convenient, which can not only ensure the overall structural strength but also effectively save the installation cost.

[0017] 2. In the utility model, an adjusting component is arranged at the bottom of the support, which can finely adjust the height of the support, thereby raising the height of the cross beam and the platform to better bolt to the outer seat of the air cooler. Because in the actual application process, there will be problems such as uneven installation site and insufficient height of the cross beam. At this time, if using additional or reduced pads to adjust the height, the first disadvantage is insufficient accuracy, and the second disadvantage is insufficient stability. Setting the adjusting component can adjust the height within a certain range, effectively solving this problem. Description of the drawings

[0022] The following will clearly and completely describe the concept, specific structure and technical effects generated of the utility model in combination with the embodiments and the drawings to fully understand the purpose, features and effects of the utility model.

[0023] Embodiment 1

[0024] As Figure 1 and Figure 2As shown in the figure, a maintenance platform applicable to the exciter cooler is provided, which is characterized in that: it includes a platform 1, a bracket 3 and a ladder 4. The platform 1 is provided with a guardrail 2. The platform 1 is provided with a notch, and a coupling hole is provided on the other side of the notch. The ladder 4 is arranged on the adjacent side of the notch. The brackets 3 are fixedly arranged at both ends on the same side of the platform 1. There are two brackets 3, and a cross beam 5 is arranged between the brackets 3. There are mounting holes on the cross beam 5. An adjusting component is arranged at the bottom of the bracket 1.

[0025] The adjusting component includes a movable bracket and screws. The movable bracket can freely expand and contract along the height direction of the bracket 3. The movable bracket is equidistantly provided with a number of through holes for cooperating with the screws. The adjusting range of the adjusting component is 0-10 mm. The purpose of setting the adjusting component is to finely adjust the height. Usually, the height is lifted five times, with a lift of 2 mm each time. This precision can fully meet the assembly adjustment requirements.

[0026] For the air-air cooler used in the exciter, the maintenance platform is designed in an overall modular manner, which can not only further ensure the personal safety of construction workers and reduce construction risks, but also has the advantage of high fit. The gap between the maintenance platform and the outer seat of the air cooler is small, and there is no maintenance risk. The overall modular design is convenient for on-site installation, disassembly and transportation for reuse.

[0027] During use, the platform 1 is completely built on the outer seat of the air cooler. The coupling holes provided on the platform 1 can be well coupled to the outer seat of the air cooler. The cross beam 5 can also be installed on the outer seat of the air cooler, making the best use of the air cooler as a support to ensure good stability. The adjusting component arranged at the bottom of the bracket 3 can further facilitate assembly. The inconsistent on-site ground conditions or machining accuracy and machining standards may affect the adaptability between the maintenance platform and the air cooler. The adjusting component can finely adjust the height of the bracket to ensure that the mounting holes on the cross beam 5 and the mounting holes on the air cooler base are at the same height, ensuring their coaxiality and better coupling to the outer seat of the air cooler. If the traditional method of increasing or decreasing shims is used to adjust its height at this time, the first disadvantage is insufficient precision, and the second disadvantage is insufficient stability. By setting the adjusting component, the height can be adjusted within a certain range, effectively solving this problem and thus improving the installation efficiency.

[0028] As an implementation method of this embodiment, the cross section of the bracket 3 is rectangular or circular. An auxiliary inclined support is arranged at the connection end of the cross beam 5 and the bracket 3. The cross beam 5 is the main stress point of the maintenance platform and needs to ensure its own sufficient strength. An auxiliary support is provided to further strengthen the stiffness of the cross beam 5, and the effect is similar to that of a rib, improving the stability of the entire maintenance platform.

[0029] As an implementation manner of this embodiment, anti-slip patterns are provided on the surface of the platform 1. The anti-slip patterns can be corrugated or horizontal and vertical draw patterns. All design methods such as these that can improve the surface roughness of the platform, increase the friction factor, and increase the grip are acceptable. The anti-slip measures are not limited here, which ensures the safety of maintenance personnel and prevents accidental slipping. The escalator 4 and the auxiliary ladder are also provided with guardrails, which are designed in accordance with national standards, with better use effects and ensuring safety. The escalator 4 is provided with a safety platform. The escalator 4 at a certain height needs to be installed with a safety platform, which can enhance the safety factor and ensure personal safety. The materials of the platform 1, the bracket 3, the escalator 4, and the cross beam 5 all adopt high-strength alloy steel, which can improve the stability.

[0030] Embodiment 2

[0031] This embodiment is further elaborated on the basis of Embodiment 1, as Figure 2 shown, an auxiliary ladder is provided inside the notch of the platform 1. The air-cooled machine base cover plate can serve as the second platform. Maintenance personnel can climb from the platform 1 to the machine base cover plate through the auxiliary ladder to repair the external circulation fan of the air-air cooler. Compared with using a scaffolding, the safety factor of the maintenance platform is higher.

[0032] The above has specifically described the implementation manners of the present utility model, but the present utility model is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent or substitutions are all included in the scope defined by the claims of the present utility model.
