AI Technical Summary
The lack of personnel protection structures during the existing elevator inspection process makes it difficult for inspectors to ensure safety when they are on the top of the elevator car.
A personnel protection structure for elevator inspection is designed, including fence mechanism and anti-collision mechanism. The fence mechanism forms a surround protection by guardrails and support plates fixed to the top of the elevator cab to prevent detectors from falling. The anti-collision mechanism uses a combination of a pin, spring and mounting rod to buffer the impact of the elevator car to protect the safety of the detector.
Effectively buffer the impact of the elevator car, protect the safety of the inspectors on the top of the elevator car, avoid the occurrence of safety accidents, and do not hinder the normal progress of the inspection work.

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0022] The utility model discloses a personnel protection structure for elevator detection, which is mainly used in existing elevator detection. There is a lack of personnel protection structure, so a personnel protection structure for elevator detection is needed to ensure that the structure can provide sufficient protection and does not hinder the normal progress of the detection work.
[0023] Reference Figure 1 , Figure 2 and Figure 4 , a personnel protection structure for elevator detection, including an elevator shaft 2 and an elevator car 8, and also including:
[0024] A fence mechanism is arranged on the top of the elevator car 8;
[0025] The anti-collision mechanism includes a second fixed block 13 arranged on the top of the elevator car 8, a mounting rod 7 is arranged on the top of the second fixed block 13, a top rod 6 is slidably connected to the inner wall of the mounting rod 7, a third spring 18 is arranged at the bottom of the top rod 6, and a first spring 5 is arranged on the top of the mounting rod 7. The first spring 5 is sleeved on the circumferential outer wall of the top rod 6.
[0026] Specifically, when a person is testing at the top of the elevator car 8 and the elevator car 8 moves upward out of control, the top rod 6 supports the top of the elevator shaft 2 and squeezes the third spring 18. At the same time, the first spring 5 is compressed to cushion the impact of the elevator car 8, thereby protecting the safety of the testing personnel at the top of the elevator car 8 and avoiding the occurrence of safety accidents.
[0027] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, a top plate 1 is provided at the top of the elevator shaft 2, a first fixed block 3 is provided at the bottom of the top plate 1, a top column 4 is provided at the bottom of the first fixed block 3, and a circular hole is opened at the bottom of the top column 4.
[0028] Specifically, when the elevator car 8 moves upward, the top rod 6 enters the circular hole, the top of the first spring 5 contacts the bottom of the top column 4, compressing the first spring 5. When the top of the top rod 6 contacts the first fixed block 3, it begins to compress the third spring 18, forming a double buffer protection, which improves the safety of the device. The top rod 6 enters the top column 4 to prevent the top rod 6 and the mounting rod 7 from tilting and forming no support, thereby effectively protecting the safety of the inspection personnel.
[0029] Reference Figure 2 and Figure 3 In a preferred embodiment, the fence mechanism includes a second support plate 12 fixed to the top of the elevator car 8, a second guardrail 11 is arranged on the top of the second support plate 12, the top of the second guardrail 11 is rotatably connected to the first support plate 10, the top of the first support plate 10 is respectively fixed with the first guardrail 9 and the third guardrail 14, one end of the first guardrail 9 is rotatably connected to the limiting block 17, the top of the limiting block 17 is provided with a limiting groove, the left and right ends of the third guardrail 14 are movably connected with symmetrically distributed movable blocks 16, one end of the movable block 16 is provided with a second spring 15, and the second spring 15 is located in the third guardrail 14.
[0030] Specifically, when the inspector is at the top of the elevator car 8, the first guardrail 9 and the third guardrail 14 are flipped upward to form an enclosure protection to prevent the inspector from falling from the edge of the elevator car 8. The movable block 16 is pressed into the third guardrail 14 to flip the first guardrail 9 and the third guardrail 14 downward and fold them for easy passage of the inspector and convenient use.
[0031] Working principle: When in use, a person is testing at the top of the elevator car 8, and the first guardrail 9 and the third guardrail 14 are flipped upward to form an enclosure protection to prevent the testing personnel from falling from the edge of the elevator car 8. When the elevator car 8 moves upward out of control, the top rod 6 enters the circular hole, and the top of the first spring 5 contacts the bottom of the top column 4, compressing the first spring 5. When the top of the top rod 6 contacts the first fixed block 3, it begins to compress the third spring 18, forming a double buffer protection to buffer the impact of the elevator car 8.
[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
