Description

Technical Field

[0001] This utility model relates to escalators, and more particularly to a multi-functional escalator safety protection device. Background Technology

[0002] In the daily operation and maintenance of highways, the stability of slopes and tunnel structures is directly related to road safety. Therefore, regular inspections of these areas are a crucial link in ensuring the safe operation of highways. Slope and tunnel inspections rely on ladders and inspection staircases located in appropriate positions; these facilities serve as important access points for inspection personnel to conduct their work in specific areas.

[0003] Slope escalators present significant limitations in terms of safety. Currently, they primarily rely on personnel simply gripping the ladder with their hands for protection. However, in reality, some slope escalators are located on steep inclines, requiring personnel to contend with substantial gravitational forces during climbing. This places extremely high demands on the physical strength and grip stability of patrol personnel. During the rainy season, the escalator surface easily becomes slippery due to rainwater, and even with a firm grip, personnel can easily slip due to reduced friction, significantly decreasing climbing speed and work efficiency, while also greatly increasing the risk of falls and injuries. Similarly, the safety issues of tunnel end-wall inspection ladders are also prominent. These ladders have a vertical structure, and compared to inclined escalators, vertical climbing inherently demands higher levels of coordination and strength from patrol personnel. During the rainy season, the vertical ladder surfaces become even more slippery. Patrol personnel must not only overcome their own weight while climbing, but also be constantly vigilant about the risk of losing their grip due to the wetness. A fall is extremely dangerous, with virtually no space for cushioning or self-rescue. This situation severely restricts the normal use of tunnel end-wall inspection ladders in adverse weather conditions such as the rainy season, making it difficult to effectively conduct safety inspections in relevant tunnel areas and hindering the timely detection and elimination of potential structural safety hazards in the tunnel. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where escalators are steep and tunnel end wall inspection ladders are vertical, making them slippery and unstable when inspecting escalators during the rainy season, resulting in slow ascent and descent, slipping and falling risks. Therefore, a multi-functional escalator safety protection device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional escalator safety protection device, including a waist belt, a fixing strap fixed to the surface of the waist belt, a round hole at one end of the fixing strap, a connecting rod passing through the round hole, U-shaped pieces fixedly connected to both ends of the connecting rod, a first hanging piece hanging inside the U-shaped piece, a connecting rope tied to the first hanging piece, a second hanging piece tied to the other end of the connecting rope, a self-locking device on one side of the waist belt, and a fall arrestor on one side of the waist belt.

[0006] Furthermore, a ring is fixedly connected to the surface of the self-locking device.

[0007] Furthermore, a protrusion is fixedly connected to one end of the fall arrestor, and a U-shaped plate is fitted onto the surface of the protrusion and pinned to it.

[0008] Furthermore, a pull rope is installed inside the fall arrestor, with one end of the pull rope passing through the fall arrestor and slidably connected to it.

[0009] Furthermore, a third pendant is attached to one end of the pull rope.

[0010] Furthermore, the protrusions of the bump and the edges of the U-shaped plate are both rounded.

[0011] Furthermore, the surface of the self-locking device has a rope hole, and the edges of both ends of the rope hole on the self-locking device are rounded.

[0012] Furthermore, the edges of the U-shaped component are all rounded.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by fixing the safety rope to both ends of the slope ladder, the patrol personnel wear safety belts and safety rope self-locking devices in advance when going up and down the ladder. The self-locking device moves up and down, and in the event of an emergency fall, the self-locking device will automatically lock and fix to the safety rope, which can prevent the patrol personnel from falling and thus achieve the function of protecting the patrol personnel.

[0015] 2. In this utility model, a fall arrestor is installed above the tunnel end wall inspection ladder. The fall arrestor is connected and fixed by a safety rope. When a slip occurs, the safety rope of the fall arrestor is pulled out at a significantly faster speed, which can automatically lock the locking system inside the device, thereby ensuring that personnel are not injured.

A self-locking device 9 is provided on one side of the waist belt 1, and a fall arrestor 11 is provided on one side of the waist belt 1, which can be used to hang the second hanging piece 8 on the self-locking device 9 or the fall arrestor 11.

[0025] Example 2, as Figures 1-4 As shown, a ring 10 is fixedly connected to the surface of the self-locking device 9; a protrusion 12 is fixedly connected to one end of the fall arrester 11, and a U-shaped plate 13 is fitted onto the surface of the protrusion 12 and pin-connected; a pull rope 14 is installed inside the fall arrester 11, and one end of the pull rope 14 passes through the fall arrester 11 and is slidably connected to it; a third hanging piece 15 is tied to one end of the pull rope 14; the protrusion of the protrusion 12 and the edge of the U-shaped plate 13 are both rounded; a rope hole is opened on the surface of the self-locking device 9, and the edges of both ends of the rope hole on the self-locking device 9 are rounded; the edges of the U-shaped piece 5 are all rounded.

[0026] The overall effect of embodiment 2 is as follows: A ring 10 is fixedly connected to the surface of the self-locking device 9, allowing the second pendant 8 to be hung on the ring 10; a protrusion 12 is fixedly connected to one end of the fall arrester 11, and a U-shaped plate 13 is fitted onto the surface of the protrusion 12 and pin-connected, allowing the second pendant 8 to be hung on the U-shaped plate 13; a pull rope 14 is installed inside the fall arrester 11, with one end passing through and slidingly connected to it, ensuring that the pull rope 14 will jam in the event of a sudden pull.

Then, the second hanging piece 8 is attached to the ring 10 on the self-locking device 9, and the first hanging piece 6 at the other end of the connecting rope 7 is attached to the U-shaped piece 5. When patrol personnel move up and down normally on the safety rope using the self-locking device 9, the self-locking device 9 can slide smoothly without affecting the normal movement of personnel, facilitating patrol personnel to carry out work on the escalator. In the event of an emergency fall on the escalator, the self-locking device 9 will automatically lock onto the safety rope, preventing the person from falling further, thus effectively preventing the patrol personnel from falling and protecting them. Simultaneously, a fall arrestor 11 is installed above the tunnel end-wall inspection ladder, and the second hanger 8 at one end of the connecting rope 7 is connected and fixed to the U-shaped plate 13 at one end of the fall arrestor 11. Then, the other end of the connecting rope 7 is fixedly connected to the U-shaped plate 5. When an inspector slips and falls on the tunnel end-wall inspection ladder, the pull rope 14 of the fall arrestor 11 will be pulled out at a significantly faster speed. This will trigger the locking system inside the fall arrestor 11, causing the locking system to automatically lock and prevent the pull rope 14 from being pulled out further, thereby preventing personnel from falling and ensuring that personnel are not injured.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
