[0028] Example 1

[0029] This embodiment discloses a mobile maintenance protection system device, which is applied to the maintenance opening of a fully underground sewage treatment plant. It protects operators who are working near the edge of the maintenance opening and operating hoisting tools, preventing them from accidentally falling into the maintenance opening and improving the safety of operators when operating hoisting tools.

[0030] The maintenance access opening is a feature of fully underground wastewater treatment plants, designed to facilitate the maintenance of underground equipment or structures. The access opening is entirely filled with wastewater, and the underground equipment and structures are situated within this wastewater. When operators are working near the edge of the access opening without any protective measures, there is a risk of them falling into the opening.

[0031] To protect operators of hoisting tools working near the edge of maintenance openings, this embodiment discloses a mobile maintenance protection system device, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes an inspection platform 1, with guardrails 2 around the inspection platform 1 and wheels 6 at the bottom of the inspection platform 1. The inspection platform 1 spans across the inspection opening 7.

[0032] In this embodiment, multiple wheels 6 are provided at the bottom of the maintenance platform 1, and the multiple wheels 6 are located on both sides of the maintenance opening.

[0033] The maintenance platform 1 is moved by the traveling wheels 6, and the relative position of the maintenance platform 1 and the maintenance opening is adjusted so that the maintenance platform 1 can be adjusted to a position that is convenient for operators to operate the hoisting tools.

[0034] In addition, after the maintenance platform 1 is moved into place, in order to ensure the stability of the maintenance platform 1, support legs 5 are set at both ends of the maintenance platform 1. The support legs 5 at both ends of the maintenance platform 1 are located on both sides of the maintenance opening.

[0035] When it is necessary to hoist and repair equipment buried underground in a fully underground wastewater treatment plant through the inspection opening, the inspection platform 1 is placed across the inspection opening. Support legs 5 on both sides of the inspection opening provide support for the platform 1. Operators stand on the platform 1 and operate the hoisting tools on one side of the inspection opening, lowering the hook into the opening to hoist the equipment. Guardrails 2 provide protection for operators and equipment on the platform 1, preventing them from falling into the inspection opening and ensuring their safety. They also prevent items from falling into the opening and damaging equipment or structures. When the operator's position needs to be adjusted, the moving wheels 6 move the platform and personnel on it.

[0036] In this embodiment, the maintenance platform 1 is defined as a rectangular maintenance platform, with both ends of the rectangular maintenance platform located on both sides of the maintenance opening, thereby allowing the maintenance platform 1 to span across the maintenance opening.

[0037] Preferably, the length of the rectangular maintenance platform is greater than the width of the maintenance opening, and the two ends of the rectangular maintenance platform along the length direction are located on both sides of the width of the maintenance opening, so that the maintenance platform 1 spans across the maintenance opening.

[0038] Preferably, a traveling wheel 6 and a support leg 5 are provided at each of the four ends of the rectangular maintenance platform 1. The two traveling wheels 6 and the support leg 5 at one end of the rectangular maintenance platform 1 are located on one side of the maintenance opening, and the two traveling wheels 6 and the support leg 5 at the other end are located on the other side of the maintenance opening.

[0039] The maintenance platform 1 is provided with stable support by the traveling wheels 6 and support legs 5 at the four ends.

[0040] The support leg 5 includes a support frame and a leg. The support frame is connected to the maintenance platform 1, and the leg is connected to the support frame and can move up and down relative to the support frame. The support frame does not contact the ground, while the leg can contact the ground. The distance of the support frame from the ground is adjusted by the relative movement between the leg and the support frame.

[0041] When the maintenance platform needs to be moved using the wheels 6, the outriggers are moved upward relative to the support frame, so that the wheels 6 contact the ground while the outriggers do not. Once the maintenance platform is in position, the outriggers are moved downward relative to the support frame, so that the outriggers contact the ground, thereby providing support for the maintenance platform and ensuring its stability.

[0042] Preferably, the support frame is a triangular support frame, with the base of the triangular support frame connected to the side of the maintenance platform, the apex of the triangular support frame away from the maintenance platform, and the outriggers located at the apex of the triangular support frame.

[0043] In this embodiment, the support leg is threadedly connected to the support frame, and the support leg can be moved up and down relative to the support frame by rotating the support leg.

[0044] To facilitate operators getting on and off the maintenance platform 1, this embodiment includes a door 4 that can be opened and closed on the guardrail 2.

[0045] In addition, this embodiment also includes lifting lugs 3 on the guardrail. The entire device is moved by suspending the lifting lugs.

[0046] Preferably, guardrails are installed around the rectangular maintenance platform, and two lifting lugs are installed on each long side of the rectangular guardrails. The device is hoisted as a whole using the four lifting lugs, which ensures the stability of the hoisting.

[0047] The mobile maintenance and protection device disclosed in this embodiment has a maintenance platform size that can accommodate all maintenance openings of the entire underground sewage treatment plant, and can span all maintenance openings of the entire underground sewage treatment plant, thereby improving the cost-effectiveness of the mobile maintenance and protection device.

[0048] This embodiment discloses a mobile maintenance and protection system device, including a maintenance platform spanning the maintenance opening, allowing operators to stand on the platform to operate hoisting tools at the maintenance opening. Guardrails provide protection for personnel standing on the platform, preventing them from falling into the maintenance opening. Furthermore, wheels are installed on the maintenance platform, enabling it to move to a suitable location within the maintenance opening, facilitating the operation of hoisting tools to lift equipment inside the opening.
