Description

Technical Field

[0001] This utility model belongs to the field of tunnel equipment technology, specifically relating to an intelligent rapid rescue stretcher for tunnel escape pipelines. Background Technology

[0002] As underground structures, tunnels face harsh construction conditions and complex surrounding rock formations, posing significant safety hazards to workers inside. Among numerous tunnel safety accidents, those caused by initial support instability leading to tunnel closure are relatively common, potentially trapping or even burying workers inside, posing a severe threat to their lives.

[0003] With the increasing number of tunnel projects, safety issues during tunnel construction and operation are receiving growing attention. In the event of an accident, the key is how to quickly and efficiently rescue trapped personnel. Previously, rescue methods after tunnel collapses mainly included the vertical shaft method, open-cut method, pilot tunnel rescue method, pipe jacking method, and large-diameter drilling rig rescue method. Among these, the large-diameter drilling rig rescue method is a relatively advanced mechanical rescue method both domestically and internationally. This method utilizes the drilling rig's unique drilling tools to penetrate the collapsed tunnel structure, and after extracting the drilling tools, an escape route is created, allowing trapped personnel to evacuate through this passage.

[0004] Currently available rescue drilling rigs can quickly create and lay escape tunnels with a diameter of 800 mm. However, escape tunnels alone are insufficient and present the following problems: uninjured personnel can crawl slowly; injured personnel are dragged using ropes and stretchers, which is time-consuming, laborious, and prone to causing secondary injuries. Therefore, a rescue stretcher trolley that can move quickly within the rescue tunnel has been specially researched to enable the rapid transfer of trapped personnel. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an intelligent rapid rescue stretcher for tunnel escape pipelines. The stretcher has a telescopic structure at both ends for easier extension and retraction, and is equipped with a camera and ultrasonic sensor to more intuitively understand the status during the journey.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart rapid rescue stretcher for tunnel escape tunnels is disclosed. The stretcher is covered with a sponge pad, and both the front and rear ends of the stretcher are equipped with telescopic joints to adjust the length of the stretcher. The bottom of the stretcher is equipped with two sets of traveling wheels and two sets of driven wheels, each of which is equipped with a hub motor. The angle between the traveling wheels is 70° to facilitate movement inside the escape tunnel. The traveling wheels are equipped with high-precision inclinometers to control the speed difference between the two wheels and achieve stable operation. A battery is also located at the bottom of the stretcher, and the hub motors are connected to the battery.

[0008] Furthermore, the telescopic joint is composed of two interlocking inner and outer tubes. The outer tube has a telescopic joint hole at the joint, and the inner tube is fitted with a V-shaped spring plate at the joint that matches the telescopic joint hole.

[0009] Furthermore, the stretcher is also equipped with a control console, which is connected to the battery; the control console is equipped with a wireless control module, which can be switched between remote and local control modes.

[0010] Furthermore, an ultrasonic sensor is installed at the bottom of the stretcher. One end of the ultrasonic sensor is connected to a battery, and the other end is connected to a control panel to detect information in front of the pipeline in real time.

[0011] Furthermore, a spotlight is provided at the bottom of the stretcher, with one end of the spotlight connected to a battery and the other end connected to a control panel.

[0012] Furthermore, a camera is installed above the stretcher, with one end connected to a battery and the other end connected to a control panel, allowing remote operation to monitor the stretcher's status in real time.

[0013] Compared with the prior art, the present invention has the following beneficial effects through the above technical solution:

[0014] This utility model provides an intelligent rapid rescue stretcher for tunnel escape tunnels. The stretcher has retractable structures at both ends for easier extension and retraction, and is equipped with a camera and ultrasonic sensors for more intuitive monitoring of the movement process. The stretcher is equipped with a high-precision inclinometer to control the speed difference between the two wheels, achieving stable operation. The entire stretcher is made of titanium alloy welding, making it lighter. After welding, burrs and sharp edges are ground off, and the corners are rounded to avoid hand injuries. This utility model has a simple structure, is easy to use, and allows trapped personnel to be quickly transferred through the escape tunnel. Attached Figure Description
