[0031] Please refer to the attached document. Figures 1-4 This application illustrates a portable construction safety ladder device for accessing storm and sewage inspection wells, which provides a safe and reliable working environment for construction personnel during the maintenance of storm and sewage wells. Specifically, it includes: a horizontal frame 1, traveling wheels 2, a vertical frame 3, a hanging ladder 6, and a fall arrestor 5.

[0032] Both the horizontal frame 1 and the vertical frame 3 are quadrilateral frames that are welded / fixed together by horizontal and vertical frames. The horizontal frame 1 is a large frame made up of two horizontal frames and two vertical frames. Its size needs to be sufficient to be placed horizontally above the well opening. The bottom of the horizontal frame 1 is fixedly installed with a traveling wheel 2, which allows the user to easily push the horizontal frame 1 to move. The bottom of the vertical frame 3 is fixedly installed on the top of the horizontal frame 1. The vertical frame 3 and the horizontal frame 1 form an inverted "T" shape. The hanging ladder 6 is hung on the first horizontal frame 101 of the horizontal frame 1, and the fall arrestor 5 is hung on the second horizontal frame of the vertical frame 3.

[0033] The movable frame, consisting of a horizontal frame 1, a vertical frame 3, and wheels 2, provides safe and reliable support at the wellhead. Furthermore, by installing a fall arrestor 5 on the vertical frame 3, one end of the fall arrestor 5 is attached to the second crossbar of the vertical frame 3, and the other end is attached to the safety belt of the construction worker, thus providing effective protection for the construction worker.

[0034] In one embodiment, a plurality of diagonal braces 4 are fixedly installed between the vertical frame 3 and the horizontal frame 1, such as... Figure 1 As shown, four diagonal braces 4 are designed and distributed on both sides of the vertical frame 3. Two diagonal braces 4 located at the same end form a triangular structure, which enables them to withstand higher loads and ensure safety during use.

[0035] In one embodiment, a handle 3a is fixedly installed at the top of the vertical frame 3. When moving the frame structure formed by the horizontal frame 1 and the vertical frame 3, the user can operate the handle 3a, which is very convenient to use.

[0036] In one embodiment, when using the hanging ladder 6, the hanging ladder 6 is hung on the first horizontal frame 101 of the horizontal frame 1. At this time, the hanging ladder 6 is prone to swaying. By fixing a counter-bracing member 7 on one side of the hanging ladder 6, the end of the counter-bracing member 7 is laterally abutted against the inner wall of the well opening, thereby ensuring the stability of the hanging ladder 6 during use. Two counter-bracing members 7 are symmetrically arranged to ensure the left and right stability of the hanging ladder 6.

[0037] The counter-support component 7 is generally made of metal square / round tube. The end of the counter-support component 7 is fixedly connected to a pad 7a. In actual use, the pad 7a abuts against the inner wall of the wellhead, thereby preventing the end of the counter-support component 7 from colliding with the inner wall of the wellhead and causing damage.

[0038] In one embodiment, the hanging ladder 6 includes: a ladder body 601 and a side ladder 604.

[0039] The ladder 601 consists of two parallel vertical frames as its skeleton, and several parallel and equidistant horizontal frames are connected between the two vertical frames. A hook 602 is fixedly installed at the top of the ladder 601. Generally, the hook 602 is directly installed at the top of the vertical frame to make its load-bearing capacity large. The counter-bracing member 7 is also generally fixedly installed on the vertical frame. A folding opening 605 is opened on the front side of the ladder 601. The side ladder 604 is a half ladder, and the side ladder 604 is rotatably connected to the horizontal brace of the ladder 601. The side ladder 604 corresponds to the folding opening 605.

[0040] To facilitate the user in opening the side ladder 604, a handle is fixedly connected to the side of the side ladder 604; to ensure that the side ladder 604 does not wobble and open when it is inside the folding opening 605, a rotatable limiting plate is installed on the front side of the ladder body 601. The limiting plate can be rotated to the front of the folding opening 605 to restrict the opening of the side ladder 604.

[0041] When working inside storm and sewage wells, in some cases it is necessary to work on the well wall or it is inconvenient to fall into the well. It is necessary to work on the hanging ladder. At this time, the user can unfold the side ladder 604. The side ladder 604 and the ladder body 601 form a T-shaped structure. The user has a larger working space when standing on the hanging ladder 6, which can meet some complex storm and sewage well operations.

[0042] In one embodiment, in order to ensure the stability of the connection between the hook 602 and the first crossbeam 101, a crossbeam 603 is fixedly connected to the top of the hook 602. The crossbeam 603 is connected to the first crossbeam 101 through a U-shaped hoop 8, thereby avoiding the problem of the hook 602 and the first crossbeam 101 shaking and falling off, and improving the safety of construction.

[0043] To ensure that the side ladder can be fully inserted into the folding opening 605, the number of sections of the side ladder is less than the number of sections of the ladder body.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
