[0029] The above-mentioned structural frame is composed of multiple platforms 1 connected together, and each of the multiple platforms 1 is provided with through holes;

[0030] The aforementioned straight ladder body 2 is disposed through multiple of the aforementioned through holes;

[0031] One of the multi-level platforms 1 is provided with an extension escalator support 3 on its side wall. One end of the escalator body 4 is detachably connected to the extension escalator support 3, and the other end is detachably connected to the ground.

[0032] The above structure is constructed by connecting multiple platforms 1, each of which has through holes. The main body 2 of the straight ladder is placed inside the platform 1. An extension escalator support 3 is set on the side wall of one of the platforms 1, and the escalator body 4 is set on the extension escalator support 3. This allows the straight ladder and escalator combination teaching aid to demonstrate both straight ladders and escalators simultaneously, avoiding the drawback of having to use multiple teaching aids to demonstrate both straight ladders and escalators. This enables elevator technicians to master the structure and operating principles of straight ladders and escalators from a single device.

[0033] Preferably, one of the multi-level platforms 1 has an extension escalator support 3 on its side wall, and one end of the escalator body 4 is detachably connected to the extension escalator support 3. By providing the extension escalator support 3, the connection of the escalator body 4 is made more secure. Without the extension escalator support 3, the area of ​​the platform 1 would be affected, limiting the user's movement space on the platform 1. Simultaneously, the detachable connection of one end of the escalator body 4 to the extension escalator support 3 and the connection of the other end to the ground improves the stability of the straight escalator combination teaching aid.

[0034] The aforementioned platform 1 is composed of multiple steel beams, which intersect to form a mesh-like structure. The steel beams include main beams and secondary beams; the main beams are made of thickened steel bars, while the secondary beams are made of ordinary steel bars. Preferably, rubber mats can be laid on the mesh-like platform 1 formed by the multiple main beams and secondary beams to improve the flatness of the platform 1 and facilitate user movement and work on it.

[0035] Multiple platforms 1 are connected by four columns 5, which are detachably connected to the ground by bolts. The four columns 5 strengthen the support between the platform 1 and the ground, and the detachable connection by bolts facilitates the installation and disassembly of this straight ladder and escalator combination teaching aid, making it suitable for a wide range of scenarios.

[0036] Tripods 8 are provided at the connection points between the aforementioned column 5 and the aforementioned platform 1, and the tripods 8 are used for auxiliary support. That is, tripods 8 are provided above and below the connection points between the platform 1 and the column 5, which enhances the stability of the connection between the column 5 and the platform 1, making the column 5 less prone to shaking.

[0037] The platform 1 is equipped with a guardrail 6 at its edge, and both ends of the guardrail 6 are bolted to the uprights 5. The guardrail 6 protects the safety of workers on the platform 1, making it less likely for users to fall.

[0038] Ladders 7 are provided between adjacent platforms 1. Users can use the ladders 7 between platforms 1 to go to different levels of platforms 1 and enter the elevator body 2 of the corresponding platform 1 to perform operations.

[0039] The shape of the aforementioned through hole matches the shape of the aforementioned straight ladder body 2, and the through hole is connected to the aforementioned straight ladder body 2 by bolts. Typically, the through hole is rectangular in shape, and the bolt connection between the straight ladder body 2 and the through hole further enhances the stability of this straight ladder and escalator combination teaching aid.

[0040] The height between the lowest platform 1 and the ground is greater than or equal to the height of the elevator pit. That is, the height of the elevator pit is reserved between the lowest platform 1 and the ground, so that the elevator body 2 can be easily installed and maintained.

[0041] Both the aforementioned elevator body 2 and the aforementioned escalator body 4 are equipped with drive devices. The two drive devices are used to control the operation of the aforementioned elevator body 2 and the aforementioned escalator body 4 respectively. That is, both the elevator body 2 and the escalator body of this elevator-escalator combination teaching aid are operable and operable, which helps users to more intuitively understand and master the structure, operating principle and other content of elevators.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
