Description

Technical Field

[0001] This utility model relates to the technical field of maintenance ladder equipment, specifically to a maintenance ladder. Background Technology

[0002] Outdoor maintenance ladders, also known as fixed steel straight ladders, are fixed to buildings or equipment and installed perpendicular to the horizontal plane. They consist of a straight ladder, a platform, a safety cage, and an upper walkway. The height of a single ladder section should generally not exceed 10 meters. When a single section exceeds 10 meters, multiple sections are required. For multi-section ladders, platforms must be designed in the middle. Maintenance ladders are indispensable tools for maintenance personnel when inspecting ladders. With social development, the demand for ladders is increasing, and the maintenance issues are also becoming more numerous. Built-in maintenance ladders provide timely convenience for maintenance personnel and also avoid the safety hazards caused by external ladders being left inside the ladder structure.

[0003] During use, construction workers found that during maintenance, manual support was required to hold the ladder steady to ensure stability, thus increasing labor costs. Furthermore, maintenance personnel had to carry numerous tools, which were prone to falling at heights, increasing workload and reducing efficiency. Additionally, the ladder's poor stability posed safety hazards for workers operating at heights. Utility Model Content

[0004] The purpose of this utility model is to address the problems encountered by construction workers during maintenance. For example, when climbing and maintaining a ladder, workers need to manually support it to ensure stability, which increases labor costs. Furthermore, maintenance personnel need to carry numerous tools, which are prone to falling at heights, increasing workload and reducing efficiency. Additionally, the ladder's poor stability poses safety hazards during high-altitude operations. This utility model provides a maintenance ladder.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A maintenance ladder includes a base, a baffle fixedly connected to the front end of the base, a support block provided at the rear end of the baffle, two slots opened at the left and right ends of the support block, a front support frame inserted into the slots, multiple pedals fixedly connected to opposite sides of the inner wall of the front support frame, a rear support frame fixedly connected to the rear end of the pedals, and the multiple pedals are equidistantly distributed on opposite sides of the inner walls of the front and rear support frames, with the bottom end of the rear support frame abutting against the rear end of the support block on the base, a hook fixedly connected to the left side of the top of the front support frame, and a toolbox fixedly connected to the left side of the hook.

[0007] Furthermore, a hanging rod is fixedly connected to the top of the rear support frame, and the two hanging rods are symmetrically distributed.

[0008] Furthermore, two handrails are fixedly connected to both ends of the front support frame.

[0009] Furthermore, multiple anti-slip frosted sleeves are fixedly connected to the surfaces of the two handrails.

[0010] Furthermore, a cotton core is fixedly pasted inside the toolbox, and multiple placement holes are opened inside the cotton core, into which different wrenches are inserted.

[0011] Furthermore, multiple anti-slip pads are fixedly attached to the surface of the pedal, and the anti-slip pads are the same size as the pedal.

[0012] Furthermore, the lower end of the base is fixedly connected with multiple spikes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a rear support frame with a fixed hanging rod at its top. The two hanging rods are symmetrically distributed and can be hung against the side of the wall that needs maintenance. This also secures the ladder, ensuring stability for workers climbing it. Two handrails are fixedly connected to both ends of the front support frame. These handrails provide support for workers climbing the ladder, allowing them to maintain stability. Because the step plates are the same size, the front and rear support frames remain parallel under the constraint of the step plates. Therefore, the handrails are parallel to the front support frame, making it easy for workers to grip the handrails while climbing. The handrails facilitate ladder climbing operations and prevent falls from heights.

[0015] 2. In this utility model, multiple anti-slip frosted sleeves are fixedly connected to the surfaces of the two handrails. The outer wall of the handrail is covered with anti-slip frosted sleeves, which can increase the friction between the hand and the palm of the maintenance personnel, preventing slippage and avoiding danger to the maintenance personnel. A cotton core is fixedly pasted inside the toolbox, and multiple placement holes are opened inside the cotton core. Different wrenches are inserted into the placement holes. When using maintenance tools at height, the toolbox can be opened. At this time, the toolbox is neatly classified and will not be mixed with various tools. Secondly, when maintenance personnel search for tools in the toolbox during the maintenance process, they will not pull out other tools and drop them. It is convenient to retrieve and put away tools, improves work efficiency, saves time in retrieving tools, and is convenient to carry and use, thus bringing a certain degree of efficiency to the staff. The classified storage of various tools brings convenience to the maintenance personnel.

[0016] 3. In this utility model, multiple anti-slip pads are fixedly attached to the surface of the footboard, and the anti-slip pads are the same size as the footboard. The anti-slip pads help prevent maintenance personnel from slipping during the climbing process. The length of the anti-slip pads is the same as the length of the footboard. When a person stands on the footboard, their feet bend to a certain extent towards the concave part of the anti-slip pad, thereby making their feet fit more tightly with the anti-slip pad, thus improving the stability of the maintenance personnel standing on the footboard and preventing safety accidents. Multiple spikes are fixedly connected to the lower end of the base. The spikes installed at the bottom of the base can enhance the grip of the base, thereby enhancing the stability of the bottom of the ladder and further enhancing the stability of the ladder when it is fixed against the wall.
