Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a crawler-type electric oxygen cylinder transport vehicle. Background Art

[0002] Oxygen is an indispensable material for medical rescue, and it is also one of the necessary medical supplies for medical teams in the field. Oxygen cylinders are large in size and heavy in weight, and have high requirements for transportation and loading and unloading. They must be moved and placed with care, and must not collide, slide, roll, or fall, and must avoid collisions with each other to prevent explosion accidents. Since the volume of oxygen cylinders is limited, exposure to the sun will increase the temperature of the medium in the bottle, causing a sudden increase in the pressure in the bottle, which puts the oxygen cylinder in a dangerous state. Oxygen cylinders should be protected from exposure to the sun and high temperatures during transportation, especially in summer. Existing oxygen cylinder transfer vehicles have a simple structure and imperfect explosion-proof measures. They mainly use manual pushing and pulling for transportation. In the field, they are restricted by environmental conditions such as terrain and complex climate, and transportation is time-consuming and labor-intensive. Therefore, there is an urgent need to design an electric oxygen cylinder transfer vehicle to realize the electric transfer of oxygen cylinders. Summary of the Invention

[0023] like Figure 1-9 As shown, the utility model takes the transport of 10 L oxygen cylinders as an example, and the implementation method of the transport vehicle is as follows:

[0024] The transfer vehicle consists of a carriage 1 and a tracked chassis 2. The vehicle measures 1200 mm long, 800 mm wide, and 1400 mm high, with the carriage 1 measuring 1000 mm high and the running structure 400 mm high. The left and right side door panels 6 measure 800 mm long by 600 mm wide. The entire vehicle is coated with a heat-insulating and sun-blocking coating that combines reflective and radiant properties with hollow microbead insulation. This highly reflective coating effectively blocks infrared and ultraviolet radiation from the sun, preventing heat buildup in the carriage 1 and ensuring the safety of the oxygen cylinders.

[0025] The two sides of the carriage 1 are rotatably connected with side door panels 6 that can be flipped downward to open. The side door panels 6 are supported and opened by electric telescopic rods. When the side door panels 6 are opened, it is convenient to load and unload the oxygen cylinders.

[0026] An oxygen cylinder fixing device is provided inside the carriage 1, and the oxygen cylinder fixing device includes an oxygen cylinder support plate 25 and a fixing frame 27. A silicone pad 28 is fixed to the top of the oxygen cylinder support plate 25. A plurality of circular grooves are arranged on the silicone pad 28. The lower end of the oxygen cylinder is embedded in the circular groove, and the oxygen cylinder is kept in an upright state by the limit of the fixing frame 27. The silicone pad has the function of preventing tipping and shock. Silicone can also be provided on the inside of the fixing frame 27 to fix the oxygen cylinder while avoiding bumps during transportation, and also to avoid the risks caused by friction between the oxygen cylinder and the fixing frame 27. In addition, a shockproof rubber ring 24 is provided on the outer wall of the oxygen cylinder to prevent collisions between oxygen cylinders and prevent the risks caused by collisions between oxygen cylinders during transportation.

[0027] A slider 26 is fixed to the top of the oxygen cylinder supporting plate 25, and a guide rail 13 adapted to the slider 26 is fixed to the inner wall of the side door panel 6. When the side door panel 6 is opened, the entire oxygen cylinder fixture can be slid along the guide rail 13, which makes it convenient to get on and off the oxygen cylinder fixture.

[0028] Inside the carriage 1 is an electrical control box 12, which contains a battery and control circuitry. This control circuitry can be wirelessly connected to a smart terminal, allowing remote control of the entire transport vehicle. The area where the electrical control box is located is separated from the oxygen cylinder storage area by fireproof insulation panels 10 and 11. These panels are made of a fireproof and heat-insulating material, such as nano-aerogel, which offers excellent thermal insulation, fire retardancy, electrical insulation, and durability.

[0029] The top of the carriage 1 is connected to an electrically operated retractable canopy 7. The upper front baffle 4 of the carriage 1 is an arc-shaped structure, on which an ultrasonic rangefinder 8 is installed to measure the presence and distance of obstacles on the top of the carriage 1. A CCD camera 5 is installed above the front baffle of the carriage 1 to capture images of the surrounding environment while the transfer vehicle is in motion.

[0030] A retractable shed storage box 9 is provided on the top rear side of the carriage 1; the electric retractable shed 7 is stored in the retractable shed storage box 9 on the rear side of the carriage 1, and is controlled to expand and contract by a hydraulic rod. When the electric retractable shed 7 is expanded, it is located on the top of the carriage 1, and the front end of the electric retractable shed 7 abuts against the silicone strip 3 of the front upper baffle 4, which is used to prevent the oxygen cylinders from being exposed to the sun during transportation, avoiding dangerous incidents caused by excessive temperature inside the cylinders, and also serves as a rain shield on rainy days. The electric retractable shed 7 is made of aluminum alloy and can withstand ordinary collisions. When the electric retractable shed 7 is expanded, it is not connected to the side door panels 6 on the left and right sides of the carriage 1, and the carriage 1 remains ventilated to avoid dangerous incidents caused by the temperature inside the carriage 1 being higher than the outside temperature.

[0031] A lead-free oxygen sensor 14, a temperature and humidity sensor 15 and a weighing sensor 16 are provided in the carriage 1; the lead-free oxygen sensor 14 is used to monitor the oxygen concentration in the carriage 1 in real time. When the oxygen cylinder in the carriage 1 leaks and the oxygen concentration is higher than the normal value, an alarm will be prompted on the smart terminal; the temperature and humidity sensor 15 monitors the temperature and humidity around the oxygen cylinder in real time and displays it on the smart terminal, and the temperature is traceable; the weighing sensor 16 is used to measure the total weight of the oxygen cylinder, so that medical staff can quickly evaluate whether the total oxygen volume is sufficient for protection without having to calculate the total oxygen volume by counting the oxygen content of each bottle; during use, changes in the total weight of the oxygen cylinder can indicate the degree of oxygen consumption; and whether the total weight of the oxygen cylinder in the non-use state changes can also indicate whether the oxygen cylinder has leaked. The weighing sensor 16 works together with the lead-free oxygen sensor 14 to improve the accuracy of the oxygen leak alarm.

[0032] The crawler chassis 2 is in the shape of an inverted trapezoid, and can cross small obstacles whether moving forward or backward. The crawler chassis 2 includes a main drive wheel 22, an auxiliary drive wheel 21, a track chain 19, and a support frame 20. The support frame 20 is the connection area between the crawler structure and the carriage 1, and an ultrasonic rangefinder 17 is provided at the front and rear of the crawler chassis 2 for accurate positioning and judging the distance to obstacles. Infrared sensors 18 are provided at the front and rear and on both sides of the crawler chassis 2 structure as collision detection sensors, which can automatically turn and detour when obstacles such as stones and trees are sensed; an infrared sensor 23 is provided at each of the four corners of the bottom as a road condition detection sensor to prevent the occurrence of stepping on air.

[0033] The specifications and sizes of the transfer vehicle in this embodiment are used to further understand the present invention and do not constitute a limitation to the present invention.

[0034] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
