[0025] Embodiments

[0026] Reference Figure 1The utility model provides an elevator guardrail with self-help alarm function, which comprises a plurality of guardrail rods 1, characterized in that: a notch is arranged on the guardrail rod 1, and two ends of the notch are fixedly connected with alarm devices 2; the alarm devices 2 are connected with transmission wires 4; and the other end of the transmission wires 4 is provided with a first alarm button 5. The alarm devices 2 comprise a shell, a control board, an alarm module, a power module and a second alarm button 3. The alarm module is an audible and visual alarm. The power module is a rechargeable and detachable battery module. The transmission wires 4 are spiral curve ropes. The control board is provided with a data storage module.

[0027] During elevator maintenance work, the maintenance personnel carry the first alarm button 5 into the elevator shaft for work. When encountering a dangerous situation, such as feeling that the self is in a dangerous situation or finding that the elevator equipment is abnormal, the maintenance personnel can quickly press the first alarm button 5. At this time, the audible and visual alarm of the alarm device 2 immediately sends out strong sound and light signals, attracting the attention of the surrounding personnel. If the maintenance personnel encounter an emergency near the guardrail, the second alarm button 3 on the surface of the shell of the alarm device 2 can also be directly pressed to trigger the alarm. After hearing the alarm sound or seeing the warning light, the outside personnel can timely understand that the elevator maintenance personnel encounter danger and take rescue measures quickly. During use, if the battery of the power module is insufficient, the rechargeable and detachable battery module can be taken out, charged by using a special charger, or replaced with a fully charged battery module, so that the alarm device 2 is always in a normal working state. During the work process, the maintenance personnel can hang the maintenance tools on the hooks for convenient use at any time; at the same time, the warning signboard can be hung on the hooks to remind the surrounding personnel to pay attention to safety.

[0028] The control board is adopted as a core component, and the microprocessor, signal processing circuit and the like are integrated on a circuit board by adopting integrated design, so that the signals from the buttons can be quickly and accurately processed and the alarm module can be controlled. The alarm module selects an audible and visual alarm, the sound loudness of which can be set to 80-100 decibels, and the light brightness is enough to be clearly visible in a relatively dark environment. The power module adopts a rechargeable lithium battery pack matched with a charging management circuit, so that the battery can be safely and efficiently charged and powered. At the same time, the second alarm button 3 is installed at a suitable position on the surface of the shell, the button should have good touch and obvious identification, and is convenient to operate.

[0029] In a preferred embodiment, the shell has the same shape as the notch of the guardrail rod 1. In this way, the alarm device 2 is integrated with the guardrail rod 1, and is more beautiful.

[0030] In a preferred embodiment, the transmission wire 4 is a spiral curve rope. In this way, the spiral curve rope has good stretchability. The inner conductor of the spiral curve rope should use a multi-strand copper core wire to ensure good electrical conductivity and flexibility. According to actual needs, the transmission wire 4 with a length of 2-5 meters is cut. For example, for a smaller elevator shaft, a 2-meter long transmission wire 4 can be selected; for a larger elevator shaft or a complex working environment, a 5-meter long transmission wire 4 can be selected.

[0031] The transmission wire 4 is connected with the alarm device 2 through a socket, which includes a male head and a female head. The male head is arranged at the end of the transmission wire 4, and the female head is arranged on the alarm device 2. This connection method facilitates the installation and disassembly of the transmission wire 4 and the alarm device 2, and facilitates the maintenance and replacement of the equipment.

[0032] In a preferred embodiment, the guardrail 1 is also provided with a hook for hanging maintenance tools or warning signs. The guardrail 1 is also provided with a hook for hanging maintenance tools or warning signs, which facilitates the placement of tools by maintenance personnel, and also allows the hanging of warning signs, further enhancing the safety warning effect.

[0033] In a preferred embodiment, the guardrail 1 is provided with a fluorescent sticker. The guardrail 1 is provided with a fluorescent sticker, which can emit fluorescence in an environment with insufficient light, making the guardrail more eye-catching and playing a better warning role, preventing personnel from accidentally touching or approaching the elevator shaft.

[0034] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
