Description

Technical Field

[0001] The utility model relates to the technical field of generator-related equipment, and in particular to a maintenance platform. Background Art

[0002] A channel steel bracket is installed between the stator base of the generator and the concrete wall in the wind tunnel of the hydropower station. Since the channel steel is a hollow structure, during the maintenance of the unit, wooden strips and solid aluminum alloy plates are generally used for temporary laying on the generator outlet platform in the wind tunnel of the hydropower station (which needs to be removed during the operation of the unit), and personnel use mobile telescopic ladders for climbing to carry out tasks such as disconnecting and connecting the generator and inspecting the generator outlet insulation basin.

[0003] The ambient temperature in the generator wind tunnel is relatively high (greater than 35°C), and the temperature at the generator outlet area is much higher than the ambient temperature of the wind tunnel, so it needs to rely on air coolers for ventilation and heat dissipation. The installed solid aluminum alloy plate itself is heavy and lacks portability, and it has the disadvantages of blocking and sealing, so the generator outlet area cannot be reliably ventilated and heat dissipated; if wooden slats are used, the wooden slats will deform greatly after bearing weight, have weak rigidity and low reliability; and mobile telescopic ladders need to rely on personnel ladders, which are prone to falling objects and being hit by objects from high places, and the safety of personnel is low.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Please refer to Figure 1-Figure 5 The utility model provides a maintenance platform, including a platform device arranged at the generator outlet, the platform device includes a supporting platform and a ladder device, the supporting platform includes a plurality of rectangular grid plates 3 and two oblique angle grid plates 2, and the two oblique angle grid plates 2 are arranged at both ends of the rectangular grid plates 3 connected into a whole.

[0028] Adjacent rectangular grid plates 3 are detachably connected. Specifically, after the angled grid plate 2 is combined with the rectangular grid plate 3, a certain gap will appear. Since the working area around the generator is narrow, the gap can be fitted with other equipment to give other equipment a certain amount of space, making the entire platform design more reasonable.

[0029] Secondly, the detachable connection can be achieved by opening holes on both sides of the rectangular grid plate 3 or the angled grid plate 2, and then arranging bolts and nuts in the through holes to achieve detachable connection.

[0030] A skirting board is provided on the side of the angled grille plate 2 away from the rectangular grille plate 3. The skirting board includes a fixed frame 1 and a clamping plate 5 arranged in the fixed frame 1. The fixed frame 1 is connected to one side of the angled grille plate 2. The skirting board can prevent objects from falling when working on the maintenance platform.

[0031] A ladder device is provided on one side of any angled grid plate 2, and the ladder device is used for workers to climb.

[0032] Preferably, it also includes a channel steel 17, two first connecting plates 16 and a plurality of connecting bolts, wherein the first connecting plate 16 is provided with a plurality of threaded holes, wherein one of the first connecting plates 16 is arranged at the bottom of the rectangular grating plate 3 or the angled grating plate 2, and the other first connecting plate 16 is clamped between the two first connecting plates 16 by connecting bolts, and the channel steel 16 is used to support the rectangular grating plate 3 or the angled grating plate 2, and the strength of each platform is enhanced by installing the channel steel 17.

[0033] Secondly, two second connecting plates 15 are also included. The second connecting plates 15 are fixedly arranged at the connection between two adjacent rectangular grid plates 3 to strengthen the overall structure of the rectangular grid plates 3 .

[0034] In one embodiment of the utility model, the ladder device includes a ladder frame 4, a first fixing device and a second fixing device, the first fixing device and the second fixing device are respectively connected to the two ends of the ladder frame 4, the first fixing device is used to fix the ladder frame 4 to one side of the angled grating plate 2, and the second fixing device is used to fix the ladder frame 4 to the ground.

[0035] Specifically, the first fixing device includes an L-shaped bracket 6 and a U-shaped buckle 7. One end of the L-shaped bracket 6 is connected to the angled grating plate 2, and the other end is connected to the ladder frame 4 through the U-shaped buckle 7. The L-shaped bracket 6 is an L-shaped structure with a bent portion at one end, and is connected to the ladder frame 4 at the bent portion by bolts and nuts. The U-shaped buckle 7 is a sheet structure with an arc in the middle. The ladder frame 4 is fitted with the arc-shaped concave portion of the U-shaped buckle 7, and the two ends of the U-shaped buckle 7 are disassembled and connected to the L-shaped bracket 6 by bolts and nuts to complete the fixation.

[0036] In an exemplary implementation of the utility model, since the ladder frame 4 is purchased in a unified manner, but the installed support platforms are at different heights from the ground, a height adjustment device is also provided. The overall length of the ladder device is adjusted by the height adjustment device so that the ladder frame 4 can be smoothly fixed to the ground. The height adjustment device includes a telescopic device and a connecting device. One end of the telescopic device is connected to the second fixing device, and the other end is connected to the bottom of the ladder frame 4 through the connecting device.

During normal use, the connecting tube 10 contacts the upper surface of the rotating handle 12, and the rotating handle 12 directly limits the connecting tube 10 to control the height of the entire ladder frame 4.

[0038] When the overall length of the ladder device needs to be extended, the rotating handle 12 can be rotated. The raising or lowering of the rotating handle 12 directly affects the height of the connecting tube 10, thereby achieving the purpose of raising and lowering the ladder device.

[0040] Secondly, it also includes a ladder baffle 9 and a locking device 8. The ladder baffle 9 is hinged to one side of the ladder frame 4 through a hinge. The locking device 8 is used to connect and separate the ladder baffle 9 and the ladder frame 4. When the locking device 8 connects the side of the ladder baffle 9 away from the hinge to the ladder frame 4, the ladder can be blocked and locked to prevent it from accidentally entering the energized interval during operation. Regarding the locking device 8, a conventional device in the prior art can be used to achieve the purpose of unlocking and locking. For example, an L-shaped bracket 6 with a through hole is provided on the ladder baffle 9 and the ladder frame 4, and a conventional lock is used to pass the lock ring through the two L-shaped brackets 6 at the same time to lock them, or a conventional cabinet door lock is used, the lock core is set on the ladder baffle 9, and the buckle is set on the ladder frame 4.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
