Description

Technical Field

[0001] The invention relates to the technical field of steel structure installation, in particular to a detachable guard cage of a straight ladder. Background Art

[0002] Steel structure projects are widely involved in many projects, but there are many risks and dangers in the process of steel structure construction, and the requirements for safety assurance in construction are getting higher and higher, especially in the process of steel column installation. Before the steel column is hoisted, it is necessary to install a ladder on the steel column to facilitate the workers to remove the hook and carry out the next installation task. Therefore, a safe and qualified ladder is the first line of defense to ensure construction safety. In general construction, ladders without guard cages or ladders that directly weld the guard cage and the straight ladder into one are generally used. Ladders without guard cages cannot effectively protect the safety of climbing workers from the outside. Although the guard cage and ladder welded as one can effectively protect the safety of workers, it is not convenient for flexible turnover on site, thereby increasing the installation cost. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a detachable guard cage for a straight ladder, which can be flexibly turned over, improve utilization rate and reduce construction costs.

[0004] To achieve this technical purpose, the present invention adopts the following scheme: A detachable guard cage of a straight ladder comprises a guard cage and a ladder. The guard cage and the ladder are split structures. The ladder is connected to a steel column. One side of the guard cage is open, and the open side of the guard cage is plugged into the ladder.

[0005] Compared with the prior art, the present invention has the following beneficial effects: The present invention can transform the entire welded cage ladder into a detachable cage ladder, which is convenient to obtain materials and easy to manufacture. The detachable cage ladder is modularly assembled and can be spliced ​​in multiple sections according to on-site requirements. It has a high turnover rate, reduces the transportation volume, and improves transportation efficiency.

[0006] The preferred embodiment of the present invention is: The ladder comprises a plurality of ladder modules, each of which comprises two parallel vertical poles, and a plurality of pedals are arranged at intervals between the two vertical poles.

[0007] The guard cage includes several guard cage modules, each of which includes two parallel supporting columns, arc-shaped protective strips are arranged between the two supporting columns at intervals, and the protective strips are connected into a whole through vertical reinforcement strips arranged at intervals.

[0008] An L-shaped latch is provided at the upper and lower ends of the back side of each supporting column, and a sleeve adapted to the latch is provided at the upper and lower ends of the front side of the pole, and the latch is plugged into the sleeve.

[0009] The bottoms of the two uprights in each set of ladder modules are respectively provided with sleeves 2, and the upper end of the back side of each upright is provided with latches 2. The two adjacent ladder modules are connected into a whole through the latches 2 and the sleeves 2. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural diagram of the ladder module; Figure 2 It is a structural schematic diagram of the cage module; Figure 3 It is a schematic diagram of the connection between the ladder module and the cage module; Figure 4 This is a schematic diagram of the splicing of two sets of modules; Figure 5 for Figure 4 Schematic diagram of the structure of two groups of modules spliced ​​together The markings in the figure are: 1. vertical pole; 2. pedal; 3. sleeve one; 4. sleeve two; 5. pin two; 6. supporting column; 7. protective strip; 8. vertical reinforcement strip; 9. pin one. DETAILED DESCRIPTION

[0011] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0012] A detachable guard cage of a straight ladder consists of a guard cage and a ladder. The guard cage and the ladder are arranged in a split structure. The guard cage and the ladder are connected to a steel column of a building structure. One side of the guard cage is open, and the open side of the guard cage is plugged into the ladder.

[0013] In this embodiment, the ladder and the guard cage are respectively composed of multiple modules, and each ladder module is composed of two parallel vertical poles 1. The two vertical poles 1 are equal in length. A plurality of pedals 2 are evenly spaced from top to bottom between the two vertical poles 1, and the two ends of the pedals 2 are correspondingly welded to the vertical poles 1 on both sides.

[0014] Each cage module is composed of two parallel supporting columns 6, and a plurality of arc-shaped protective strips 7 are arranged at equal intervals from top to bottom between the two supporting columns 6. The two ends of the protective strips 7 are respectively welded and fixed to the supporting columns 6 on their corresponding sides, and the protective strips 7 of the same cage module are connected into a whole by a plurality of spaced vertical reinforcement strips 8.

[0015] An L-shaped latch 9 is installed at the upper and lower ends of the back side of each supporting column 6, and a sleeve 3 adapted to the latch 9 is installed at the upper and lower ends of the front side of the upright 1. The cage module is installed on the ladder module through the cooperation of the latch 9 and the sleeve 3.

[0016] The bottoms of the two uprights 1 in each set of ladder modules are respectively installed with sleeves 4, and the upper end of the back side of each upright 1 is respectively installed with L-shaped pins 5. The two adjacent ladder modules are connected to form a whole through the pins 5 and the sleeves 4.

[0017] In this embodiment, the upright pole 1, the supporting column 6, the protective strip plate 7 and the reinforcing strip are respectively made of 6*30 flat steel, and the pedal 2 is made of 12 round steel.

[0018] When the device is used, the length of the ladder connection is determined according to the on-site requirements, and then the number of ladder modules and cage modules required is determined according to the ladder connection length; the uppermost ladder module is fixedly connected to the steel pipe of the building structure, and then the cage module is correspondingly plugged in through the sleeve 1 and the pin 1 9, so that the ladder module and the cage module are connected into a module as a whole; then, the lower ladder module is mounted at the lower end of the ladder module through the cooperation of the sleeve 2 4 and the pin 2 5, and the cage module is mounted on the lower ladder module, and the above steps are repeated to install the remaining ladder modules and cage modules downwards and splice them in sequence to complete the assembly of the cage ladder as a whole.

[0019] In this embodiment, if the length of the ladder is long, after the ladder is assembled, flat steel can be used to temporarily fix each section of the ladder to the steel column to increase the stability of the ladder.

[0020] The invention connects multiple sections of the guard cage according to the length and number of ladder connections, which not only can protect the safe construction of operators, but also has convenient material acquisition, simple production, high turnover rate, reduced material waste, and saved construction costs.

[0021] Finally, it should be noted that the above-listed embodiments are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
