Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to an assembled quick-disassembly step ladder applied to an operation frame system. Background Art

[0002] With the continuous development of the construction engineering industry, higher requirements are also put forward for the conditions of on-site construction operations. For example, it is difficult to install equipment in the elevator shaft due to its narrow space; the construction of the exterior wall is difficult and has a high risk coefficient due to the characteristics of high-altitude operations. Under such construction operations, ordinary workers and managers cannot reach the construction operation surface by climbing the operation frame. In order to meet the needs of these construction scenarios and ensure the safety and efficiency of production, at present, the traditional method of erecting steel pipe ladders is usually adopted to ensure on-site construction operations.

[0003] At present, scaffolds are mostly used on construction sites to erect safety step ladders, which are mainly composed of scaffold vertical poles, horizontal bars, diagonal bars, base pedals and diagonal beams. Its base size is 1.8m×3.6m, and each section is 2 meters long. During construction, it is lapped according to the on-site height requirements to meet the use requirements. For a long time, scaffold steel pipe ladders have been used on a large scale, but they have more connecting parts, the erection operation is relatively complex, the erection time is long and the efficiency is low. Moreover, due to its single-section lapping method, the erection scenario is easily limited, it is difficult to meet the requirements in extreme scenarios such as large spans and high altitudes, there is a possibility of illegal erection, the safety risk is relatively large, and at the same time, it also faces problems such as difficult turnover use and low utilization rate.

[0004] In order to solve the above problems, it is particularly necessary to design a new type of assembled quick-disassembly step ladder applied to an operation frame system. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide an assembled quick-disassembly step ladder applied to an operation frame system, which has a simple structure, reasonable design, convenient operation, improves on-site operation efficiency, reduces labor and material costs, improves utilization turnover rate and operation safety, has strong practicability and is easy to popularize and use.

[0006] In order to achieve the above purpose, the utility model is realized through the following technical solutions: An assembled quick-disassembly step ladder applied to an operation frame system includes side frames, hook claws and steps. First chutes and first locking pulleys are respectively arranged at both ends of the side frames. Second chutes and second locking pulleys are respectively arranged on both side surfaces of the hook claws. The steps are inserted into the left and right side frames to form a single-step ladder. Between multiple single-step ladders, adjacent side frames are spliced and locked in pairs by using the first chutes and first locking pulleys to connect and form a step ladder main body. One end of the step ladder main body is fixedly connected to the second locking pulley of the hook claw through the first chute, and the other end of the step ladder main body is fixedly connected to the second chute of the hook claw through the first locking pulley.

[0007] Preferably, the length of the side frame is 900mm and 1500mm; the length of the hook is 400mm and 450mm, and the width of the main body of the step ladder is 600mm, so that different installation requirements can be met through different combinations.

[0008] Preferably, both ends of the step ladder body are hooked on the steel pipes between the upper and lower layers by hooks.

[0009] The beneficial effects of the utility model are as follows: the device is easy to operate and can be easily and quickly erected. After being assembled once, it can be quickly installed across layers without repeated assembly and disassembly, which greatly improves on-site operation efficiency, reduces labor and material costs, improves utilization turnover rate and operation safety, and has broad application prospects.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] Reference Figure 1-7The present specific embodiment adopts the following technical scheme: an assembled quick-detachable step ladder used in an operating frame system, comprising a side frame 1, a hook 2 and a step 3, both ends of the side frame 1 are respectively provided with a first slide groove 4 and a first locking pulley 5, and the two sides of the hook 2 are respectively provided with a second slide groove 6 and a second locking pulley 7, the step 3 is plugged into the side frames 1 on the left and right sides to form a single step ladder, and a plurality of single step ladders are connected and locked in pairs by using the first slide groove 4 and the first locking pulley 5 through adjacent side frames 1 to form a step ladder body. One end of the step ladder body is connected and fixed to the second locking pulley 7 of the hook 2 through the first slide groove 4, and the other end of the step ladder body is connected and fixed to the second slide groove 6 of the hook 2 through the first locking pulley 5, and the two ends of the step ladder body are hung and buckled on the steel pipe between the upper and lower layers through the hook 2.

[0020] It is worth noting that the length of the side frame 1 is 900mm and 1500mm; the length of the hook 2 is 400mm and 450mm, and the width of the step ladder body is 600mm. Through different combinations and an additional adjustable length within a range of 400mm, it can meet the requirements of setting up steel pipe operating frames and disc-lock operating frames with a step and longitudinal distance between 900mm-1800mm.

[0021] The installation method of this specific embodiment is as follows: (1) the side frame 1 is connected to the hook 2 by connecting the first slide groove 4 and the first locking pulley 5 with the second locking pulley 7 and the second slide groove 6 respectively, adjusting the required length according to the site conditions, and tightening the pulley to lock;

[0022] (2) Insert the steps 3 into the side frames 1 on the left and right sides to achieve the effect of stair steps;

[0023] (3) Buckle the hooks 2 at the front and rear ends of the step ladder into the steel pipes between the upper and lower layers respectively. At this point, the quick-release step ladder is installed;

[0024] (4) When the slide groove is extended to the maximum but still cannot meet the use requirements, the side frames 1 can be spliced ​​and locked in pairs, and then the above operation can be repeated.

[0025] This specific implementation adopts a 600mm wide single-run finished hanging ladder, which is hung on the steel pipe with hooks and can be quickly assembled and disassembled. Its technical advantages are:

[0026] (1) Quick installation and disassembly: Prefabricated quick-disassembly step ladders use prefabricated components and standardized connectors, making the installation and disassembly process quick and easy. All components of the step ladder are prefabricated and preassembled, and only simple assembly operations are required during on-site installation, greatly saving construction time.

[0027] (2) Reusability: The components of the quick-detachable step ladder are made of reusable materials and connectors, and can be disassembled and assembled repeatedly, making it suitable for temporary construction or event needs. This reusability allows the step ladder to be repeatedly used in multiple construction sites or different projects, thereby reducing costs and reducing resource waste.

[0028] (3) Standardized design: The quick-detachable step ladder adopts a standardized design. The connection method and size specifications between the components are relatively uniform, making the manufacture and installation of the step ladder easier and also facilitating on-site management and maintenance.

[0029] (4) Wide applicability: Prefabricated quick-disassembly step ladders are suitable for various construction sites and activity venues, including construction sites, temporary activity venues, exhibition venues, etc., and due to their flexible assembly and disassembly characteristics, the position and layout of the step ladder can be adjusted at any time according to actual needs.

[0030] (5) Safety and stability: The quick-release step ladder has good stability and safety after installation. Its structural design takes into account various loads and usage conditions to ensure safety when going up and down the stairs.

[0031] (6) Space saving: The assembled quick-detachable step ladder adopts lightweight materials and compact design structure, which can provide an effective passage without taking up too much space. It is especially suitable for construction sites or temporary activity venues with limited space.

[0032] (7) Reduce construction costs: Quick-disassembly step ladders use prefabricated components and standardized connectors to reduce the workload of on-site processing and assembly, thereby reducing construction costs. In addition, since the installation and disassembly process is quick and easy, labor and time costs are reduced, the overall construction cost can be reduced.

[0033] This specific implementation method can achieve one-time assembly and rapid installation and turnover across layers without repeated assembly and disassembly. While achieving rapid installation and turnover, it can also achieve length adjustment within a range of 400mm, can meet the needs of multiple scenarios, and has no restrictions on the erection scenarios, greatly improving construction efficiency, achieving the goals of cost control and green construction, and has broad market application prospects.
