Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, specifically a safety platform for high-altitude operations in generator wind tunnels. Background Technology

[0002] In existing technology, during preventative testing of the generator during spring and autumn maintenance, it is necessary to disconnect the primary leads of the outlet and neutral point. The distance from the generator cover plate to the lead connection point in the pit is limited by the site environment and equipment operation mode. There is no sufficiently large ladder support platform or stable ladder top handrail connection point, and no climbing device is installed, seriously endangering the personal safety of workers. There is a risk of workers falling from heights and injuring themselves, trampling on the generator stator bars, and potential insulation damage, making generator maintenance complex and more dangerous. To meet the needs of safe production on site, a safe foot platform specifically designed for workers to climb up and down is proposed, meeting the requirement that the working safe load does not exceed its maximum allowable load. Utility Model Content

[0003] The purpose of this utility model is to provide a generator wind tunnel high-altitude operation safety platform with a reasonable structure and safe use, in order to address the above-mentioned shortcomings.

[0004] The technical solution of this utility model is: a safety platform for high-altitude operations in a generator wind tunnel, comprising two interlocking left and right frames, with multiple steps on both sides of the left and right frames, and interlocking tie rods between the middle of the left and right frames, forming a working platform on the left and right frames, the working platform being composed of multiple platform plates connected in sequence, one of which is fixedly connected to the frame by a fixing pin.

[0005] The aforementioned plug-in connection consists of a locking nut on the connector and a slide for the locking nut to move in sequence.

[0006] The platform consists of three sections: a first platform section, a second platform section, and a third platform section. The platform sections are connected by hinges, and the first platform section is fixedly connected to the frame by a fixing pin.

[0007] The advantages of this utility model are: 1. It adopts a telescopic structure, consisting of three sections, each of which can be effectively connected by hinges. The number of sections can be flexibly increased or decreased according to the number of workers, making it convenient to use and store. 2. It allows on-site workers to climb up and down to perform operations, ensuring their safety and reliability in tasks such as disconnecting generator leads and replacing test wiring for high-voltage testing. 3. It allows for safe and convenient disconnection and reconnection of generator primary leads, enabling timely generator maintenance and electrical testing. This eliminates safety hazards, shortens the time for disconnecting and reconnecting primary leads, improves work efficiency, and ensures high reliability, guaranteeing the safety of workers at heights and the project schedule. 4. This platform has the advantages of high efficiency, safety, strong adaptability, and simple operation.

[0008] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0010] See Figure 1 The component names are as follows: Left frame 1, Right frame 2, Step 3, Locking nut 5, Slide 4, Tie rod 6, First platform plate 7, Second platform plate 8, Third platform plate 9, Hinge 10, First platform plate fixing pin 11.

[0011] See Figure 1 The generator wind tunnel high-altitude operation safety platform includes two interlocking left frames 1 and right frames 2. Multiple steps 3 are located on both sides of the left and right frames 1 and 2. A connecting brace 6 is interlocked between the left and right frames 1 and 2 in the middle to ensure sufficient support strength and accommodate changes in overall size. The interlocking connection consists of a locking nut 5 on the connecting body and a sliding track 4 for the locking nut 5 to move. The brace 6 consists of two sections, left and right, overlapping in the middle. Each overlapping section has a sliding track 4, and the locking nut 5, which passes vertically through the sliding track 4, can be used to lock or loosen the platform. The upper surfaces of the left frame 1 and right frame 2 form a working platform of a certain width. This platform consists of three sequentially connected platform panels: the first platform panel 7, the second platform panel 8, and the third platform panel 9. The platform panels are connected by hinges 10, allowing them to be stacked. The first platform panel 7 is fixedly connected to the frame by fixing pins 11, facilitating the stacking of the second and third platform panels 8 on top of it without detaching from the left frame 1. The three-panel platform allows three people to work simultaneously. The platform panels are covered with striped high-quality rubber for effective anti-slip. When the third platform panel 9 is stacked on top of the second platform panel 8, it can be pushed against the left and right frames 1 and locked, allowing two people to work. The three platform panels stacked together allow one person to work, representing the smallest possible storage configuration. The left and right frames 1 and 2 can be pulled together to form a work platform of variable size. The left frame 1, right frame 2, steps 3, tie rods 6, first platform board 7, second platform board 8, and third platform board 9 are made of insulating epoxy resin, providing high support strength and load-bearing capacity, allowing workers to stand and climb up and down. Other accessories can be added. The platform ends are equipped with striped high-quality rubber pads for anti-slip purposes, enhancing ladder stability and effectively preventing slippage on the horizontal surface.

[0012] When in operation, it is laid horizontally to meet load-bearing requirements. It consists of two sets of side ladders and three-section safety platforms. Section hinges: These tightly connect the two sets of side ladders to the section platforms, serving as auxiliary connections. The number of section hinges can be adjusted according to the number of section platforms. While ensuring reliable and stable connection of the high-altitude work platform, it effectively enhances platform safety, storage capacity, and practicality.

[0013] Instructions for use: When storing, stack the first platform panel 7, the second platform panel 8, and the third platform panel 9 together from bottom to top, with the left frame 1 and the right frame 2 close together, and tighten the locking nut 5 to achieve the smallest possible volume. When using, loosen the locking nut 5, pull apart the left frame 1 and the right frame 2, unfold the first platform panel 7, the second platform panel 8, and the third platform panel 9, and tighten the locking nut 5 before use.

[0014] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
