Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction ladder technology, specifically an engineering construction ladder. Background Technology
[0002] In various construction scenarios, workers frequently need to operate at different heights, such as in building exterior wall construction, and the installation and maintenance of equipment at heights. To meet the vertical movement needs of construction workers, construction ladders have become an indispensable tool.
[0003] Traditional construction ladders have a relatively simple structure and generally only have basic climbing functions. They do not have a dedicated tool storage area, so construction workers can only hold the tools in their hands or on their bodies. This not only affects the convenience of construction operations, but also makes it easy for tools to fall and cause safety accidents or damage to the tools.
[0004] With the increasing demands on engineering construction, higher requirements are being placed on the functionality and safety of construction ladders. Therefore, developing a construction ladder with a stable structure, auxiliary facilities, and convenient tool storage is of significant practical importance. Utility Model Content
[0005] (a) Technical problems to be solved The purpose of this utility model is to solve the problem that traditional construction ladders are relatively simple in structure, generally only have basic climbing functions, and do not have a dedicated tool storage area. Construction workers can only hold the tools in their hands or on their bodies, which not only affects the convenience of construction operations, but also easily causes safety accidents or damage to the tools due to tools falling. Therefore, this utility model proposes a construction ladder.

The upright frame is provided with a tool placement mechanism.

[0008] Preferably, the placement mechanism includes a limiting mechanism, with two limiting mechanisms slidably connected to the outer sides of both top frames, the right ends of the four limiting mechanisms being fixedly connected to the placement platform, and two guardrails being fixedly connected to the top of the placement platform.
[0009] Preferably, the limiting mechanism includes a sliding sleeve, which is slidably connected to the outer side of the top frame, and a screw is threadedly connected to the inner side of the sliding sleeve.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] In the embodiments, by Figure 1-4 A construction ladder is provided, comprising a vertical frame 1, a horizontal frame 2 fixedly connected to the left end of the vertical frame 1, the vertical frame 1 and the horizontal frame 2 being fixedly connected by an inclined ladder 3, a load-bearing plate 4 fixedly connected to the top end of the vertical frame 1, two top frames 5 fixedly connected to the top end of the vertical frame 1, the inclined ladder 3 being fixedly connected to the two top frames 5 by handrails 6, and a tool placement mechanism 7 being provided on the vertical frame 1.
[0018] With the above setup, before climbing, place small tools or items in the placement mechanism 7, ensuring both hands can freely grip the handrail 6. Always face the inclined ladder 3, alternately gripping the handrail 6 with both hands, and steadily stepping on each step, ascending step by step. Once safely at the top, stand on the support plate 4. The support plate 4 provides a safer and more comfortable standing area than a regular ladder crossbar. When working on the support plate 4, keep your body as close to the ladder as possible. If necessary, you can lightly lean your abdomen or one side of your body against the top frame 5 to maintain balance. Accessing tools from the placement mechanism 7 on the upright 1 eliminates the need for frequent climbing, enabling efficient work.
[0019] Reference Figure 1-4 The placement mechanism 7 includes a limiting mechanism 71. Two limiting mechanisms 71 are slidably connected to the outer sides of the two top frames 5. The right ends of the four limiting mechanisms 71 are fixedly connected to the placement platform 72. Two guardrails 73 are fixedly connected to the top of the placement platform 72. With the above-described structure, before climbing, the construction worker stands on the ground and uses their hands to slide the placement platform 72 down along the slide rail of the limiting mechanism 71 to a height that is easy to reach. The tools and materials required for this operation are then placed steadily on the placement platform 72, and the guardrail 73 is used to surround the platform to ensure that the items do not roll off.
[0020] Reference Figure 1-4 The limiting mechanism 71 includes a sliding sleeve 711, which is slidably connected to the outer side of the top frame 5. A screw 712 is threadedly connected to the inner side of the sliding sleeve 711. The end of the screw 712 abuts against the top frame 5. A grip 713 is fixedly connected to the outer side of the screw 712. Several protrusions 714 are provided on the outer side of the top frame 5. The protrusions 714 are evenly distributed. The lower part of the screw 712 abuts against the protrusions 714. With the above structural design, when the height of the placement platform 72 needs to be adjusted, the operator rotates the handle 713 counterclockwise by hand. Rotating the handle 713 causes the screw 712 to move backward (inward into the sliding sleeve 711), disengaging its end from the currently pressed protrusion 714 or separating it from the surface of the top frame 5. At this point, the pressure of the screw 712 on the top frame 5 disappears, and the lock between the sliding sleeve 711 and the top frame 5 is released. The operator can now freely slide the entire limiting mechanism 71 up and down, thereby moving the connected placement platform 72 to a new ideal height.
[0021] Reference Figure 1-4 The placement platform 72 includes a support frame 721. The right ends of two adjacent limiting mechanisms 71 are fixedly connected to the support frame 721. A placement plate 722 is fixedly connected between the two support frames 721. The placement plate 722 is fixedly connected to the two support frames 721 through two diagonal rods 723. Through the above structural arrangement, the diagonal brace 723, the support frame 721, and the placement plate 722 form a triangular stable structure. A triangle is the most stable geometric shape in mechanics, effectively resisting shear and torsional forces, ensuring the geometric shape of the entire platform frame remains unchanged, thereby eliminating unstable swaying.
[0022] Reference Figure 1-4 Both the upright frame 1 and the horizontal frame 2 are equipped with two casters 8 at their bottom ends; With the above structural design, construction workers do not need to laboriously carry or drag the entire ladder; they can easily move the ladder in any direction with just a gentle push.
