Description

Technical Field

[0001] This utility model relates to the field of rail vehicles, specifically a single-tooth rail personnel transport device for coal mine roadways. Background Technology

[0002] Due to the complex working environment in mines, many locations are inaccessible by existing transportation, requiring workers to walk to and from get off work, which is physically demanding. There is an urgent need to equip workers with efficient and safe equipment for transporting people in confined spaces, thereby reducing the labor intensity of their commute and improving convenience.

[0003] Currently, some rail transport vehicles have certain limitations in their transportation methods. For example, they have defects in the anti-slip properties of the tracks, which can easily cause slippage in wet or steeply inclined tunnels, leading to runaway accidents and limiting the ability to transport vehicles on slopes.

[0004] Moreover, it lacks spatial adaptability. Traditional personnel carriers are often wider than 1.2m and use double tracks, making them unable to pass through narrow alleys. Furthermore, the multi-track setup increases the cost of the device. Additionally, diesel-powered personnel carriers emit pollutants into the alley air, and the rigid suspension structure results in severe vibrations during driving, leading to insufficient comfort.

The bottom end of the frame 106 is engaged with both ends of the track 800, and the pin wheel 104 is rotatably mounted on the frame 106 on one side of the frame 106. The frame 106 has a first bearing wheel 102 that can roll on the rectangular tube 801. Four first guide wheels 103 are rotatably mounted on the frame 106. The four first guide wheels 103 are located below the pin wheel 104. When the frame 106 clamps the rectangular tube 801, the four first guide wheels 103 are arranged in pairs, located on both sides of the rectangular tube 801 and in contact with the bottom surface of the rectangular tube 801.

[0052] In another embodiment, the difference between this embodiment and the previous embodiment is that the second guide wheel 206 and the second load-bearing wheel 205 are set to different sizes, which are selected according to the load-bearing weight of the cabin. If the load-bearing weight of the cabin is large, the design of the second load-bearing wheel 205 being larger than the second guide wheel 206 can be used in this embodiment.

[0053] A horizontal rotating shaft 203 is rotatably provided in the middle of the rotary table 201. A vertical rotating shaft 208 is fixed on the trolley frame 207.

[0058] Specifically, when the hydraulic pump station is working, the hydraulic motor 109 converts hydraulic energy into mechanical energy and transmits the power to the pin wheel 104, enabling the drive unit 100 to move on the track 800. When braking is required, the brake 108 can apply the brakes.

[0059] The electronic control module 500 is installed on the main driver's cabin 400.

The hydraulic energy is converted into mechanical energy through the hydraulic motor 109. The hydraulic motor 109 drives the pin wheel 104, which meshes with the rack 802 for transmission.

[0070] The main / co-pilot cabin control electronic control module 500 adjusts the hydraulic pressure of the hydraulic pump station, thereby adjusting the speed of the hydraulic motor 109. The pin wheel 104 rolls along the rack 802, and the first bearing wheel 102 rolls on the rectangular tube 801 to provide support.

[0071] Steering adaptation:
