Description

Technical Field

[0001] This utility model belongs to the field of elevator construction equipment technology, specifically relating to a portable elevator maintenance guardrail. Background Technology

[0002] When elevator maintenance and safety inspection personnel perform repairs and safety inspections on elevators and escalators, they need to place guardrails at the base station and working floors. This serves two purposes: firstly, to prevent unauthorized personnel from entering the work area, and secondly, to act as a warning, preventing unauthorized personnel from interfering with elevator operations and causing unnecessary injury. Currently, while the guardrails used in the market provide some protection, they still have the following shortcomings in use: their overall size is too large, making them difficult to carry and move. Summary of the Invention

[0003] In order to overcome the problems of the current guardrails in the background technology being too bulky, difficult to carry, and inconvenient to move, this utility model provides an easy-to-carry elevator maintenance guardrail that can be conveniently stored and moved when not in use.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A portable elevator maintenance guardrail mainly includes a storage box, a support frame, a movable guardrail, and a push-pull handle. The storage box has an open design at one end. The support frame is installed inside the storage box and is welded from two horizontal balance beams and two support columns. The horizontal balance beams are telescopic structures with grooves on their surfaces. The movable guardrail is slidably installed on the support frame and includes a guardrail frame and a movable column. The guardrail frame is hinged to the movable column, and both ends of the movable column are slidably installed in the grooves. The push-pull handle is installed on a support column on one side of the support frame.

[0005] Furthermore, the guardrail frame is formed by hinged two guardrails.

[0006] Furthermore, the horizontal beam is a three-stage telescopic structure.

[0007] Furthermore, the storage box has a snap-fit ​​structure on one side of its open end.

[0008] The beneficial effects of this utility model are:

[0009] This utility model features a retractable support frame. The retractable structure can be adjusted in length according to the working area, making it suitable for various occasions and greatly reducing the space occupied by the device. When not in use, it can be neatly stored for easy carrying. The movable guardrail is slidably connected to the support frame, and the position of the movable guardrail can be adjusted according to the length of the support frame, increasing flexibility and practicality.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] This utility model discloses a portable elevator maintenance guardrail. The portable elevator maintenance guardrail mainly includes a storage box 1, a support frame 2, a movable guardrail 3, and a push-pull handle 4. One end of the storage box 1 is open. The support frame 2 is installed inside the storage box 1 and is welded from two horizontal beams 201 and two support columns 202. The horizontal beams 201 are telescopic structures with grooves 5 on their surfaces. The movable guardrail 3 is slidably mounted on the support frame 2 and includes a guardrail frame 301 and movable columns 302. The guardrail 301 is hinged to the movable column 302, and the two ends of the movable column 302 are slidably installed in the sliding groove 5. The push-pull handle 4 is installed on the support column 202 on one side of the support frame 2. This utility model, by setting a telescopic support frame 2, can adjust the length according to the working area, and is suitable for various occasions, greatly reducing the space occupied by the device. When not in use, it can be well stored, making it easy to carry. The movable guardrail 3 is slidably connected to the support frame 2. This structure can be adjusted according to the length of the support frame 2, increasing flexibility and practicality.

[0016] The guardrail frame 301 is composed of two guardrails hinged together; this structural design facilitates the storage or unfolding of the device.

[0017] The horizontal beam 201 is a three-stage telescopic structure; when unfolded, the three-stage telescopic structure can expand the protection range, facilitate the sliding of the movable guardrail 3 on the support frame 2, and at the same time, facilitate the storage of the support frame 2 and the movable guardrail 3 into the storage box 1.

[0018] The storage box 1 has a buckle structure on one side of the opening end; after the movable guardrail 3 and the support frame 2 are stored in the storage box 1, they can be locked in the storage box 1 by the buckle structure to prevent them from sliding out.

[0019] Working process: In actual use, the device is moved to the elevator maintenance point, and then the support frame 2 is pulled out by pushing and pulling handle 4. Then, the movable guardrail 3 is pulled on the support frame 2 to distribute it evenly on the support frame 2. After the maintenance work is completed, the support frame 2 and the movable guardrail 3 can be pushed into the storage box 1 together by pushing and pulling handle 4. This utility model has a telescopic support frame 2. The telescopic structure can be adjusted in length according to the working area, which is suitable for various occasions and greatly reduces the space occupied by the device. When not in use, it can be stored well, making it easy to carry. The movable guardrail 3 is slidably connected to the support frame 2. This structure can be adjusted according to the length of the support frame 2, which increases flexibility and practicality.

[0020] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
