Description

Technical Field

[0001] This application relates to the field of robotic vehicle technology, and in particular to a robotic vehicle equipped with a multifunctional long-tube respirator. Background Technology

[0002] Long-tube breathing apparatus, also known as a mobile air supply, is a personal protective equipment that protects the respiratory system of workers by continuously delivering clean air. When workers are engaged in firefighting operations, they can achieve long-distance breathing protection by using long-tube breathing apparatus.

[0003] The existing robotic respirator includes a frame, four wheels mounted at the bottom of the frame, a handle fixed to the upper side of the frame, a composite gas cylinder mounted on the inner wall of the frame, a decompression system located on the inner wall of the frame, a reel mounted in the middle of the frame, a medium-pressure hose wound around the outside of the reel, and an air supply valve mounted on the upper side of the frame. The medium-pressure hose is connected to the decompression system, which is connected to the composite gas cylinder. When workers use the robotic respirator, they push the respirator to the work location using the handle, and then use the reel to take out the medium-pressure hose to deliver air to the workers at a distance, thus achieving long-distance breathing protection.

[0004] The above process relies on gas cylinders for gas supply, which is a single method. When working for a long time, it is necessary to constantly replace the consumed gas cylinders, making the gas supply process relatively complex and requiring improvement. Utility Model Content

[0005] In order to increase the number of air supply methods so that there is no need to replace the consumed air cylinders when working for a long time and to simplify the process of providing air source, this application provides a machine vehicle equipped with a multi-functional long tube respirator.

[0006] This application provides a robotic vehicle equipped with a multi-functional long-tube respirator, which adopts the following technical solution:

[0007] A robotic vehicle equipped with a multi-functional long-tube respirator includes a frame, a power unit disposed on the lower side of the frame, several gas cylinders mounted on the side wall of the frame, a storage box fixed to the upper side of the frame, a winding drum rotatably connected to the side wall of the storage box, a pressure-reducing assembly mounted on the side wall of the storage box, and a medium-pressure pipe wound around the side wall of the winding drum. The power unit is used to drive the frame to slide. The pressure-reducing assembly connects the gas cylinders and the medium-pressure pipe respectively. The side wall of the storage box is also provided with an air supply pipe. The inner wall of the storage box is provided with a quick-connect fitting. The air supply pipe can be connected to a fire water pipe. The inner wall of the quick-connect fitting can abut against the side wall of the air supply pipe. The quick-connect fitting is connected to the medium-pressure pipe.

[0008] By adopting the above technical solution, when workers use the fire truck for firefighting, they can move the truck to the work area by using the power unit. At this time, workers install the quick-connect fittings on the inner wall of the air supply pipe, connecting the air supply pipe to the medium-pressure pipe. Then, workers install the fire hose on the side wall of the air supply pipe and connect the gas cylinder to the medium-pressure pipe. Workers can then supply air through the medium-pressure pipe, thus realizing the switching and practicality of multiple air sources. This setting increases the air supply methods, eliminating the need to replace consumed gas cylinders when working for a long time, and simplifying the process of providing air sources.

[0009] Optionally, the pressure reducing assembly includes a pressure reducing element fixed to the side wall of the storage box, a high-pressure pipe communicating with the gas cylinder, and a pressure reducing pipe communicating with the pressure reducing element. The high-pressure pipe is communicating with the pressure reducing element, and the pressure reducing pipe can be communicating with the medium-pressure pipe.

[0010] By adopting the above technical solution, the pressure reducing device makes it easier for staff to adjust the pressure of the high-pressure gas output from the gas cylinder, thereby reducing the damage to the equipment caused by pressure fluctuations and reducing the possibility of staff being affected by the pressure, thus increasing the safety of the vehicle.

[0011] Optionally, the pressure reducing assembly further includes a high-pressure gauge fixed to the side wall of the pressure reducing component, a medium-pressure gauge fixed to the side wall of the pressure reducing component, and an alarm whistle installed on the side wall of the storage box. The high-pressure gauge is used to detect the air pressure of the high-pressure pipe, the medium-pressure gauge is used to detect the air pressure of the pressure reducing pipe, and the alarm whistle is electrically connected to the pressure reducing component.

[0012] By adopting the above technical solutions, the installation of high-pressure gauges, medium-pressure gauges, and alarm whistles makes it easier for staff to judge the pressure during the gas supply process, thereby enabling staff to perform maintenance or replacement of parts on the machine vehicle before an accident occurs, further increasing the safety of staff when using the machine vehicle.

[0013] Optionally, a number of straps are fixed to the upper side of the vehicle frame. The straps are arranged opposite to the gas cylinder and can abut against the side wall of the gas cylinder.

[0014] By adopting the above technical solution, the straps reduce the possibility of the gas cylinders shifting during the sliding of the machine vehicle, thereby reducing collisions between gas cylinders and lowering the possibility of gas cylinder safety accidents.

[0015] Optionally, a baffle is fixed to the side wall of the vehicle frame, and the side wall of the gas cylinder can abut against the side wall of the baffle. Several quick-release parts are fixed to the side of the vehicle frame away from the baffle, and the side wall of the quick-release parts can abut against the side wall of the gas cylinder. The baffle and the quick-release parts cooperate to limit the position of the gas cylinder.

[0016] By adopting the above technical solution, the baffle and quick-release mechanism reduce the possibility of the gas cylinder slipping off the frame. At the same time, when the staff installs the gas cylinder, they can remove the quick-release mechanism to install the gas cylinder, which simplifies the operation of the staff installing the gas cylinder.

[0017] Optionally, the side wall of the take-up drum is equipped with an anti-rotation pin, the side wall of which can abut against the inner wall of the take-up drum.

[0018] By adopting the above technical solution, the anti-rotation pin reduces the possibility of the winding drum rotating during operation, thereby making the air supply process of the machine more stable.

[0019] Optionally, the storage box has a lid hinged to its upper side, and a handle is fixed to the upper side of the lid.

[0020] By adopting the above technical solution, the design of the lid and handle makes it easier for staff to move the storage box, which in turn makes it easier for staff to manually control the sliding of the robot, thereby increasing the robot's ability to move in complex terrain.

[0021] Optionally, the power unit includes a tracked vehicle disposed on the lower side of the frame, a rear wheel rotatably connected to the lower side of the frame, and a swivel wheel fixed to the side of the frame away from the rear wheel, wherein the rear wheel and the swivel wheel are both located above the tracked vehicle.

[0022] By adopting the above technical solution, the tracked vehicle is designed to facilitate the movement of the machine in complex terrain, and the rear wheels and casters make it easy for workers to move the machine by dragging it with a handle. This design improves the mobility of the machine, enabling it to work in various complex terrains.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When workers use the fire truck for firefighting, they install the gas cylinder onto the side wall of the truck frame, and then install the quick-connect fittings onto the side wall of the air supply pipe. At this point, the gas cylinder is connected to the medium-pressure pipe, and the air supply pipe is also connected to the medium-pressure pipe. Workers then install the fire hose onto the outside of the air supply pipe. Workers then drive the fire truck to the waiting area using the power unit. At this time, the gas cylinder on the fire truck supplies gas to the workers after passing through the pressure reducing component. This setup increases the gas supply methods, eliminating the need to replace consumed gas cylinders during long working hours and simplifying the gas supply process.

[0025] 2. The installation of high-pressure gauges, medium-pressure gauges, and alarm whistles simultaneously detects the gas pressure inside both the high-pressure and pressure-reducing pipes. This allows staff to monitor the gas supply process in a timely manner, thereby increasing the safety of the gas supply process. Attached Figure Description
