Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and in particular to a multi-functional trolley for ventilation inside high-altitude tunnels. Background Technology

[0002] When constructing tunnels at high altitudes, the high altitude, thin air, and low atmospheric pressure result in extremely low natural ventilation efficiency and a significant drop in oxygen content, easily triggering safety issues such as altitude sickness and asphyxiation among construction workers. Simultaneously, dust, blasting fumes, exhaust fumes from internal combustion equipment, and harmful gases released from the geological formations generated during tunnel excavation are difficult to remove in a timely manner, causing a deterioration in air quality inside the tunnel and seriously threatening the health of workers and construction safety.

[0003] Currently, conventional tunnel ventilation mainly relies on jet fans for air supply or exhaust, requiring the transportation and placement of these fans in suitable locations. Currently, jet fans are generally transported using electric hoists. However, in high-altitude, long-distance tunnels, a large number of jet fans need to be installed, and the installation and use of electric hoists are inconvenient, resulting in low efficiency in the transportation and placement of jet fans.

[0004] Therefore, a multi-functional vehicle for ventilation inside high-altitude tunnels needs to be designed to solve the above problems. Utility Model Content

[0005] To overcome the drawback of low handling efficiency of jet fans, this utility model provides a multi-functional trolley for ventilation inside high-altitude tunnels.

[0006] The technical solution is as follows: A multi-functional trolley for ventilation inside high-altitude tunnels includes an electric tricycle, a seat, a mounting frame, a controller, a fan, a ferrule, a rotating frame, wheels, a fork sleeve, a fork support, and insert rods. A seat is fixedly connected to the top right side of the electric tricycle. A mounting frame is fixedly connected to the right side of the electric tricycle. A controller is fixedly connected to the top of the mounting frame. A fan is placed on the top left side of the electric tricycle. Ferrules are fitted on both the front and rear sides of the fan.

The two insert rods are inserted into the slots of the two ferrules respectively.

[0007] Furthermore, it also includes a limiting frame, which is fixedly connected to the outer perimeter of the top of the electric tricycle.

[0008] Furthermore, it also includes a battery box, a lithium battery, and a socket. The battery box is fixedly connected to the bottom of the seat, and the lithium battery is slidably placed inside the battery box. A socket is provided on the right side of the battery box. The controller and the electric tricycle are both electrically connected to the lithium battery, and the lithium battery powers the controller and the electric tricycle.

[0009] Furthermore, it also includes a protective door and a latch. The protective door is rotatably connected to the front of the battery box, and a latch is installed between the right side of the protective door and the battery box.

[0010] Furthermore, it also includes sensors and alarms.

The controller 10 is fixedly connected to the top of the mounting frame 9 by bolts. The fan 13 is placed on the top left side of the electric tricycle 1. The fan 13 is fitted with ferrules 14 on both the front and rear sides. Both ferrules 14 have slots 15 on their lower right sides. The rotating frame 16 is placed on the top of the electric tricycle 1. Wheels 17 are rotatably connected to both the front and rear sides of the rotating frame 16. The fork sleeve 18 is welded to the top of the rotating frame 16. The fork support 19 is slidably connected to the lower part of the fork sleeve 18. Insert rods 20 are fixedly connected to the front and rear parts of the lower end of the fork support 19. The two insert rods 20 are respectively inserted into the slots 15 of the two ferrules 14.

[0024] like Figure 1 and Figure 2 As shown, it also includes a limiting frame 2, which is fixedly connected to the top periphery of the electric tricycle 1 by bolts.

[0025] like Figure 3 As shown, it also includes a battery box 4, a lithium battery 5 and a socket 8. The battery box 4 is fixedly connected to the bottom of the seat 3. The lithium battery 5 is slidably placed inside the battery box 4. The socket 8 is provided on the right side of the battery box 4. The controller 10 and the electric tricycle 1 are both electrically connected to the lithium battery 5. The lithium battery 5 supplies power to the controller 10 and the electric tricycle 1.

[0026] like Figure 3 As shown, it also includes a protective door 6 and a latch 7. The protective door 6 is rotatably connected to the front of the battery box 4, and the latch 7 is installed between the right side of the protective door 6 and the battery box 4.

[0027] like Figure 3 As shown, it also includes a sensor 11 and an alarm 12. The sensor 11 is fixedly connected to the front top of the mounting bracket 9 by bolts, and the alarm 12 is fixedly connected to the rear top of the mounting bracket 9 by bolts. Both the sensor 11 and the alarm 12 are electrically connected to the controller 10, and both the sensor 11 and the alarm 12 are electrically connected to the lithium battery 5. The lithium battery 5 supplies power to the sensor 11 and the alarm 12.

[0028] like Figure 5 As shown, it also includes a soft pad 21, with a soft pad 21 on the top of each of the two insertion rods 20.

[0029] like Figure 5 As shown, it also includes bolts and nuts 23. Multiple fixing holes 22 are provided on the front and rear parts of the upper part of the fork 19 and the lower part of the fork sleeve 18, and bolts and nuts 23 are provided on one fixing hole 22 on each side. The bolts and nuts 23 are detachable.

[0030] When this device is needed for ventilation work inside high-altitude tunnels, the operator first sits on the seat 3 on the right side of the electric tricycle 1, starts the electric tricycle 1, and drives it along the tunnel track or ground to the work area requiring ventilation. The electric tricycle 1 is powered by a lithium battery 5 in the battery box 4 at the bottom of the seat 3. The protective door 6 on the front of the battery box 4 is locked by a latch 7 to prevent dust and moisture from entering during construction and to ensure power supply safety. The lithium battery 5 can be removed by opening the protective door 6 for replacement or charging to ensure continuous operation of the equipment. After reaching the designated position, the fork sleeve 18 and fork frame 19 are manually moved by the wheels 17, which drives the two insertion rods 20 to be inserted into the slots 15 on the two sleeves 14 of the corresponding fans 13. The soft pads 21 on the top of the insertion rods 20 act as a buffer to prevent the fans 13 from colliding hard with metal parts. If a collision causes damage, the blower 13 is quickly positioned by the cooperation of the insert rod 20 and the clamp 14. Then, combined with the rotating frame 16 and the rotating connection of the wheel 17, force is applied to the fork sleeve 18 to pry the blower 13 up to a certain height off the ground. Then, it is moved to the right to smoothly send the blower 13 onto the electric tricycle 1. The blower 13 is then fixed with the straps. The bolt and nut 23 can be removed by twisting the bolt and nut 23. Then, the sliding height of the fork 19 in the fork sleeve 18 is adjusted. The fork 19 and the fork sleeve 18 are provided with multiple fixing holes 22. After adjusting to the appropriate height, the bolt and nut 23 are used to lock through the corresponding holes to ensure that the blower 13 is stable and does not shake during operation. In addition, the electric tricycle 1 is provided with a limiting frame 2 to prevent the blower 13, tools or other equipment from slipping during transportation, thereby improving driving safety.

[0031] After the fan 13 is loaded, the electric tricycle 1 is started to continue traveling along the tunnel track or the ground. The controller 10 receives real-time data from the sensor 11. The sensor 11 continuously monitors environmental parameters such as oxygen concentration, harmful gas concentration, dust concentration, temperature and humidity in the tunnel. When a certain indicator is detected to exceed the standard, the controller 10 automatically activates the alarm 12 to issue an audible and visual alarm, reminding on-site personnel to take countermeasures. After the staff finds out, they stop driving, get off the vehicle, unfasten the straps, and then place the fan 13 in the corresponding position by moving the fork sleeve 18 and the fork frame 19. The two plugs 20 are released from the two clamps 14 to complete the transportation. After the sensor 11 detects that the environmental parameters such as oxygen concentration, harmful gas concentration, dust concentration, temperature and humidity in the tunnel have returned to normal, the alarm 12 stops issuing alarms. Among them, the socket 8, as a key power interface, realizes the flexible distribution of power from the lithium battery 5 and the plug-and-play functionality of external devices.
