Description

Technical Field

[0001] This invention relates to the field of cockpit technology, specifically to a cockpit for construction machinery suitable for high-altitude, oxygen-deficient areas. Background Technology

[0002] The unique oxygen-deficient environment, extreme temperature differences, and strong winds and sandstorms of the plateau present unavoidable challenges to construction. Among these challenges, the health and safety of construction machinery operators remain a core bottleneck restricting project efficiency. In the plateau environment, the oxygen content in the air is only 50%-70% of that in the plains. Operators who operate machinery in this environment for extended periods are prone to altitude sickness, experiencing headaches, fatigue, and a sudden drop in blood oxygen saturation. This not only affects operational accuracy but may also lead to irreversible health risks such as cardiopulmonary damage. Traditional construction machinery cabs only provide basic wind and rain protection and lack both an active oxygen supply system and the ability to monitor and regulate the oxygen concentration inside the cab in real time, making it difficult to meet the core needs of plateau operations. To overcome this challenge and adapt to the unique construction scenarios in high-altitude regions, a new type of cockpit for construction machinery suitable for high-altitude, oxygen-deficient areas is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a cockpit suitable for construction machinery in high-altitude, oxygen-deficient areas, in order to solve the problems mentioned in the background art, such as the lack of active oxygen supply capacity and the inability to monitor and regulate the oxygen concentration in the cockpit in real time, which makes the driver prone to altitude sickness in high-altitude, oxygen-deficient environments, thus affecting the accuracy of operation and the safety of life and health. At the same time, it is difficult to adapt to the extreme temperature difference, strong winds and sandstorms in high-altitude areas, and cannot provide stable protection for equipment and personnel.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A cab for construction machinery suitable for high-altitude, oxygen-deficient areas includes: a cab, a rain shelter fixedly installed at one end of the cab, an oxygen storage mechanism fixedly installed inside the rain shelter, a first air pipe connected to one end of the exhaust end of the oxygen storage mechanism, the first air pipe extending through to the top of the cab, a first solenoid valve connected to the other end of the first air pipe, and a second air pipe connected to one end of the outer surface of the first air pipe located at the top of the cab, the other end of the second air pipe connected to a ring pipe, and an oxygen intake mechanism connected to the outer surface of the ring pipe in a damped rotatable manner.

[0005] Preferably, a windshield is rotatably mounted at one end of the cockpit, and both ends of the inner side of the windshield are rotatably connected to the piston rod of an electric push rod. The electric push rod is rotatably mounted at one end inside the cockpit, so that the electric push rod can push and pull the windshield to open and close and seal by extending and retracting the piston rod.

[0006] Preferably, the oxygen storage mechanism includes an oxygen generator, which is fixedly installed at one end of an installation frame. The installation frame is fixedly installed inside a rain shelter. One end of the oxygen output port of the oxygen generator is connected to a third gas pipe, and the other end of the third gas pipe is connected to the air inlet of a gas compressor. The air outlet of the gas compressor is connected to the air inlet of an oxygen cylinder through a gas pipe. The oxygen cylinder is fixedly installed inside a locking ring, and the locking ring is fixedly installed at one end of the installation frame.

[0007] Preferably, this allows the gas compressor to pressurize the oxygen produced by the oxygen generator and inject it into the oxygen cylinder for centralized storage. The outlet of the oxygen cylinder is connected to the first gas pipe, so that the first solenoid valve can release the oxygen in the oxygen cylinder into the cockpit by switching it on and off.

[0008] Preferably, a second solenoid valve is connected and installed in the middle section of the third air tube.

[0009] Preferably, an oxygen sensor is fixedly installed at one end of the cockpit. The signal transmitting end of the oxygen sensor is connected to the signal receiving end of the controller. The control output end of the controller is electrically connected to the electrical control ends of the oxygen generator, gas compressor, first solenoid valve, and second solenoid valve. The controller can be installed on the mounting frame and the cockpit. The models of the oxygen sensor and the controller are GYH25 and C58761P, respectively.

[0010] Preferably, the oxygen inhalation mechanism includes a ring-shaped shroud, which is damped and rotatably mounted on the outer surface of the ring tube. The upper and lower surfaces of the ring-shaped shroud are connected to a fourth air tube, and the other ends of the two sets of fourth air tubes are connected to a sealing tube. A piston tube is slidably mounted inside the sealing tube, so that the piston tube can block the two sets of fourth air tubes by sliding upward inside the sealing tube.

[0011] Preferably, the lower surface of the piston tube slides out from the lower end of the sealing tube and is connected to a bellows at the end, and the other end of the bellows is connected to an oxygen mask and hangs down to one side of the seat in the cockpit.

[0012] Preferably, a ring is fixedly installed on the inner ring wall of the piston tube, and a spring is fixedly connected to the upper surface of the ring. The upper surface of the spring is fixedly connected to the top of the sealing tube, so that the spring can apply an upward elastic force to the piston tube.

[0013] Preferably, when the driver uses the oxygen mask, he only needs to pull down the oxygen mask so that the piston tube moves down through the corrugated tube into the sealed tube, thereby allowing the piston tube to break free from the blockage of the fourth air tube and allowing oxygen to enter the oxygen mask through the piston tube and the corrugated tube for the driver to inhale.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The cockpit employs a dual-mode oxygen supply system, combining ambient oxygen supply and emergency oxygen replenishment. The ambient oxygen supply system relies on real-time monitoring by oxygen sensors and automatic regulation by controllers to precisely stabilize the oxygen concentration within the cabin within a safe range, thus preventing altitude sickness caused by conventional hypoxia.

[0015] The emergency oxygen replenishment system utilizes a purely mechanically triggered oxygen intake mechanism. Drivers can quickly obtain high-concentration oxygen by pulling down their masks to cope with sudden hypoxia symptoms. At the same time, the automated operation of the oxygen generation and storage process requires no manual intervention, which reduces the driver's workload and ensures a continuous and stable oxygen supply, thus comprehensively protecting the driver's life, health, and operational focus during high-altitude operations.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-6 This embodiment provides the following technical solution: like Figures 1-3 As shown, a cab for construction machinery suitable for high-altitude hypoxic areas includes: a cab 1, a rain shelter 103 fixedly installed at one end of the cab 1, an oxygen storage mechanism 2 fixedly installed inside the rain shelter 103, a first air pipe 104 connected to one end of the exhaust end of the oxygen storage mechanism 2, the first air pipe 104 extending through to the top of the cab 1, a first solenoid valve 105 connected to the other end of the first air pipe 104, and a second air pipe 107 connected to one end of the outer surface of the first air pipe 104 located at the top of the cab 1, and a ring pipe 106 connected to the other end of the second air pipe 107, the outer surface of the ring pipe 106 being damped and rotatably connected to an oxygen intake mechanism 3.

[0020] The windshield 101 is rotatably mounted on one end of the cockpit 1. Both ends of the inner side of the windshield 101 are rotatably connected to the piston rod of the electric push rod 102. The electric push rod 102 is rotatably mounted on one end inside the cockpit 1, so that the electric push rod 102 can push and pull the windshield 101 to open and close and seal by extending and retracting the piston rod.

[0021] Through the design of the cockpit 1, windshield 101, electric push rod 102, rain shelter 103, first air pipe 104, first solenoid valve 105, ring pipe 106, second air pipe 107, oxygen storage mechanism 2, and oxygen intake mechanism 3, when the driver enters the cockpit 1 to prepare for work in high-altitude hypoxic areas, the piston rod can be extended or retracted by controlling the electric push rod 102, thereby pushing and pulling the windshield 101 to achieve a closed seal. This reduces air exchange between the inside of the cockpit 1 and the external high-altitude hypoxic environment, laying a sealed foundation for maintaining the oxygen concentration inside the cockpit. At the same time, the rain shelter 103 can protect the oxygen storage mechanism 2 installed inside it, preventing damage to the oxygen storage mechanism 2 from harsh environments such as high-altitude rain, snow, strong winds, and sandstorms, ensuring its stable operation. When it is necessary to replenish oxygen in the cockpit 1, the oxygen storage mechanism 2 is activated and delivers oxygen to the first air pipe 104 through its exhaust end. At this time, the first solenoid valve 105 can be controlled to open, allowing a portion of the oxygen in the first air pipe 107 to directly enter the cockpit. Inside the cockpit 1, the oxygen is evenly diffused to the top of the cockpit 1 to replenish the oxygen of the entire cockpit 1 space, gradually increasing the oxygen concentration inside the cockpit to meet the driver's normal breathing needs in the hypoxic environment of the plateau. Once the oxygen concentration in the cockpit 1 reaches the set requirement, the first solenoid valve 105 will automatically close. The continuously operating oxygen storage mechanism 2 will compress and store the generated oxygen. A portion of the stored oxygen will be transported to the ring pipe 106 through the second air pipe 107 connected to the first air pipe 104. The ring pipe 106 will then transport the oxygen to the oxygen inhalation mechanism 3. If the driver experiences hypoxia during operation and needs a higher concentration of oxygen for rapid replenishment, the oxygen inhalation mechanism 3, which is connected to the outer surface of the ring pipe 106 by damping rotation, can be used. By adjusting the rotation angle of the oxygen inhalation mechanism 3 to suit the driver's posture, the oxygen inhalation mechanism 3 can be pulled down to release the stored oxygen, quickly relieving the discomfort of hypoxia. If ventilation is needed or the operation is to be completed, the windshield 101 can be opened by controlling the electric push rod 102.

[0022] like Figure 4As shown, the oxygen storage mechanism 2 includes an oxygen generator 201, which is fixedly installed at one end of a mounting frame 108. The mounting frame 108 is fixedly installed inside a rain shelter 103. One end of the oxygen output port of the oxygen generator 201 is connected to a third air pipe 202, and the other end of the third air pipe 202 is connected to the air inlet of a gas compressor 204. The air outlet of the gas compressor 204 is connected to the air inlet of an oxygen cylinder 205 through an air pipe. The oxygen cylinder 205 is fixedly installed inside a locking ring 109, which is fixedly installed at one end of the mounting frame 108. This allows the gas compressor 204 to pressurize the oxygen generated by the oxygen generator 201 and inject it into the oxygen cylinder 205 for centralized storage. The air outlet of the oxygen cylinder 205 is connected to a first air pipe 104, allowing the first solenoid valve 105 to release the oxygen from the oxygen cylinder 205 into the cockpit 1 by switching it on and off. A second solenoid valve 203 is connected to the middle section of the third air pipe 202.

[0023] An oxygen sensor 206 is fixedly installed at one end of the cockpit 1. The signal transmitting end of the oxygen sensor 206 is connected to the signal receiving end of the controller. The control output end of the controller is electrically connected to the electrical control ends of the oxygen generator 201, the gas compressor 204, the first solenoid valve 105, and the second solenoid valve 203. The controller can be installed on the mounting frame 108 and the cockpit 1. The models of the oxygen sensor 206 and the controller are GYH25 and C58761P, respectively.

[0024] Through the design of the oxygen generator 201, the third air pipe 202, the second solenoid valve 203, the gas compressor 204, the oxygen cylinder 205, and the oxygen sensor 206, when oxygen needs to be replenished in the cockpit 1, the oxygen generator 201, fixed to one end of the mounting frame 108 inside the rain shelter 103, starts first. It separates oxygen from the high-altitude air through its own oxygen-generating function. The generated oxygen enters the third air pipe 202 through its oxygen outlet. At this time, if the pressure gauge in the oxygen cylinder 205 indicates insufficient oxygen storage, the controller receives a relevant signal and controls the second solenoid valve 203 in the middle section of the third air pipe 202 to open, allowing the oxygen in the third air pipe 202 to be smoothly delivered to the inlet of the gas compressor 204. Subsequently, the controller controls the gas compressor 204. 4. Upon startup, the gas compressor 204 pressurizes the incoming oxygen and delivers it through a pipe connected to its outlet to the oxygen cylinder 205, which is fixed within the locking ring 109 at the other end of the mounting frame 108, achieving centralized oxygen storage. When the oxygen level in the oxygen cylinder 205 reaches a preset threshold, the controller first stops the gas compressor 204 and then closes the second solenoid valve 203, cutting off the oxygen supply from the oxygen generator 201 to the oxygen cylinder 205. During operation in the cockpit 1, the oxygen sensor 206, fixed at one end of the cockpit 1, continuously monitors the oxygen concentration in the cabin and transmits the detected concentration signal to the controller. When the signal received by the controller indicates that the oxygen concentration in the cabin is lower than the preset safety value, the controller will control the oxygen cylinder 205 to stop. The first solenoid valve 105 on the first air pipe 104 connected to the air outlet 05 opens, allowing the high-pressure oxygen stored in the oxygen cylinder 205 to be released into the cockpit 1 through the first air pipe 104, replenishing the oxygen in the cockpit 1. As oxygen is continuously replenished, when the oxygen sensor 206 detects that the oxygen concentration in the cabin has risen back to a preset suitable value, the signal transmitted to the controller will trigger the controller to close the first solenoid valve 105, stopping the oxygen supply from the oxygen cylinder 205 to the cockpit 1. If the oxygen in the oxygen cylinder 205 subsequently falls below the storage threshold again due to continuous use, the controller will repeat the above oxygen generation and storage process, replenishing the oxygen cylinder 205 with oxygen through the coordinated action of the oxygen generator 201, the gas compressor 204, and the second solenoid valve 203, thus maintaining the oxygen level in the cockpit 1. With the gas concentration within a safe range, the system ensures the driver's breathing needs during high-altitude operations, preventing altitude sickness symptoms such as headaches and sudden drops in blood oxygen levels due to hypoxia. This reduces the risk of cardiopulmonary damage and maximizes the protection of the driver's health and operational focus during high-altitude operations. Secondly, it employs a three-level oxygen supply logic: "real-time oxygen production by oxygen generator 201 + pressurized oxygen storage by gas compressor 204 + backup buffer by oxygen cylinder 205." Combined with a pressure gauge to monitor the oxygen cylinder 205's storage level, it can automatically activate oxygen production and compression processes to replenish oxygen when the oxygen cylinder 205's storage level is insufficient. It can also use the oxygen cylinder 205 to store oxygen to cope with temporary malfunctions of oxygen generator 201, forming a "production-storage-supply" closed loop. This avoids oxygen outages caused by the failure of a single oxygen supply link, ensuring a continuous and stable oxygen supply.

[0025] like Figures 5-6 As shown, the oxygen inhalation mechanism 3 includes a ring tube 301, which is damped and rotatably mounted on the outer surface of the ring tube 106. The upper and lower surfaces of the ring tube 301 are connected to a fourth air tube 306. The other end of the two sets of fourth air tubes 306 is connected to a sealing tube 302. A piston tube 303 is slidably mounted inside the sealing tube 302, so that the piston tube 303 can block the two sets of fourth air tubes 306 by sliding upward inside the sealing tube 302.

[0026] The lower surface of the piston tube 303 slides out from the lower end of the sealing tube 302 and is connected to a bellows 304 at its end. The other end of the bellows 304 is connected to an oxygen mask 305 and hangs down to one side of the seat in the cockpit 1. A ring 308 is fixedly installed on the inner ring wall of the piston tube 303, and a spring 307 is fixedly connected to the upper surface of the ring 308. The upper surface of the spring 307 is fixedly connected to the top of the inner part of the sealing tube 302, so that the spring 307 can apply an upward elastic force to the piston tube 303. When the driver needs to inhale oxygen, he only needs to pull down the oxygen mask 305, which will cause the piston tube 303 to slide down in the sealing tube 302 through the bellows 304. This allows the piston tube 303 to be released from the blockage of the fourth air tube 306, allowing oxygen to enter the oxygen mask 305 through the piston tube 303 and the bellows 304 for the driver to inhale oxygen.

[0027] Through the design of the annular tube 301, sealing tube 302, piston tube 303, bellows 304, oxygen mask 305, fourth air pipe 306, spring 307, and ring 308, the oxygen inhalation mechanism 3 is in standby mode under normal oxygen supply conditions in the cockpit 1. At this time, the spring 307 exerts an upward pulling force on the ring 308 on the inner wall of the piston tube 303 due to its own elasticity, causing the piston tube 303 to slide upward within the sealing tube 302. The side wall of the piston tube 303 precisely blocks the openings of the two sets of fourth air pipes 306 connected to the sealing tube 302, preventing oxygen in the annular tube 106 from entering the oxygen inhalation mechanism 3 through the fourth air pipes 306. To avoid unnecessary oxygen leakage, when the driver experiences symptoms of oxygen deficiency during operation and requires a rapid supply of high-concentration oxygen, simply pull down the oxygen mask 305 hanging on the side of the seat in the driver's cabin 1. The oxygen mask 305, through the bellows 304, drives the piston tube 303 connected to it to overcome the tension of the spring 307 and slide downwards within the sealing tube 302. As the piston tube 303 slides down, its sidewall separates from the opening of the fourth air tube 306, no longer blocking the fourth air tube 306. At this time, the oxygen in the oxygen cylinder 205 will enter the sealed tube 306 in sequence through the first air tube 104, the second air tube 107, the ring tube 106, and the fourth air tube 306. In the sealing tube 302, the air flows through the piston tube 303 and the bellows tube 304 before finally entering the oxygen mask 305 for the driver to inhale and quickly relieve hypoxia discomfort. Simultaneously, because the ring tube 301 is damped and sealed and rotates on the outer surface of the ring tube 106, the driver can adjust the position of the oxygen mask 305 according to their posture and oxygenation habits, improving oxygenation comfort. When the driver's hypoxia symptoms are relieved and continued oxygenation is no longer needed, the oxygen mask 305 can be released, and the spring 307 returns to its elastic deformation, pulling the piston tube 303 upwards again within the sealing tube 302 via the ring 308, resealing the fourth airway. At pipe 306, the oxygen supply mechanism 3 returns to standby mode, awaiting its next activation. During use, oxygen supply can be initiated simply by pulling down the mask, eliminating the need to learn complex operating procedures. In scenarios where high-altitude hypoxia leads to decreased energy, it can quickly obtain high-concentration oxygen, avoiding delays in alleviating hypoxia symptoms due to cumbersome operations. Secondly, under normal conditions, the piston pipe 303 is driven by the tension of spring 307 to block the fourth air pipe 306, physically cutting off the oxygen passage and preventing oxygen leakage when not in use. Combined with the overall oxygen supply control of the cockpit 1, this further reduces oxygen waste and lowers the oxygen supply cost for high-altitude operations.

[0028] Based on the above technical solution, the working steps of this solution are summarized as follows: When working in high-altitude hypoxic areas, after the driver enters the cockpit 1 to prepare for work, the piston rod can be extended or retracted by controlling the electric push rod 102, thereby pushing and pulling the windshield 101 to achieve a closed seal, reducing the air exchange between the inside of the cockpit 1 and the external high-altitude hypoxic environment, laying a sealed foundation for maintaining the oxygen concentration inside the cockpit. At the same time, the rain shelter 103 can protect the oxygen storage mechanism 2 installed inside it. When it is necessary to replenish oxygen in the cockpit 1, the oxygen generator 201 fixed to one end of the mounting frame 108 inside the rain shelter 103 is started first, separating oxygen from the high-altitude air through its own oxygen generation function. The generated oxygen enters the third air pipe 2 through its oxygen output port. 02. At this time, if the pressure gauge in oxygen cylinder 205 indicates insufficient oxygen storage, the controller will receive a relevant signal and then control the second solenoid valve 203 in the middle section of the third gas pipe 202 to open, allowing the oxygen in the third gas pipe 202 to be smoothly delivered to the inlet of the gas compressor 204. Subsequently, the controller controls the gas compressor 204 to start. The gas compressor 204 pressurizes the incoming oxygen and delivers it through the gas pipe connected to its outlet to the oxygen cylinder 205, which is fixed in the locking ring 109 at the other end of the mounting frame 108, to achieve centralized oxygen storage. When the oxygen storage in oxygen cylinder 205 reaches a preset threshold, the controller will first control the gas compressor 204 to stop running, and then close the second solenoid valve 203 to cut off the oxygen supply from the oxygen generator 201. The oxygen supply channel of cylinder 205 is used. During operation in the cockpit 1, an oxygen sensor 206 fixed at one end of the cockpit 1 continuously monitors the oxygen concentration in the cockpit and transmits the detected concentration signal to the controller. When the controller receives a signal indicating that the oxygen concentration in the cockpit is lower than a preset safety value, the controller will control the first solenoid valve 105 on the first air pipe 104 connected to the outlet of oxygen cylinder 205 to open, allowing the high-pressure oxygen stored in oxygen cylinder 205 to be released into the cockpit 1 through the first air pipe 104 to replenish the oxygen in the cockpit 1. As the oxygen is continuously replenished, when the oxygen sensor 206 detects that the oxygen concentration in the cockpit has risen back to a preset suitable value, the signal it transmits to the controller will trigger the controller to close the first solenoid valve 105, stopping the operation. The oxygen cylinder 205 supplies oxygen to the cockpit 1. If the oxygen level in the cylinder 205 falls below the storage threshold again due to continuous use, the controller will repeat the oxygen generation and storage process. Under normal oxygen supply conditions in the cockpit 1, the oxygen intake mechanism 3 is in standby mode. At this time, the spring 307 exerts an upward pulling force on the ring 308 on the inner ring wall of the piston tube 303 due to its elasticity, causing the piston tube 303 to slide upward within the sealing tube 302. The side wall of the piston tube 303 precisely blocks the openings of the two sets of fourth air pipes 306 connected to the sealing tube 302, preventing oxygen in the ring tube 106 from entering the oxygen intake mechanism 3 through the fourth air pipes 306, thus avoiding unnecessary oxygen leakage. When the driver experiences symptoms of hypoxia during operation and needs a rapid supply of high-concentration oxygen,Simply pull down the oxygen mask 305 hanging down beside the seat in the cockpit 1. The oxygen mask 305, through the bellows 304, drives the piston tube 303 connected to it to overcome the tension of the spring 307 and slide downwards within the sealing tube 302. As the piston tube 303 slides down, its sidewall separates from the opening of the fourth air tube 306, no longer blocking the fourth air tube 306. At this time, the oxygen in the oxygen cylinder 205 will sequentially enter the sealing tube 302 through the first air tube 104, the second air tube 107, the ring tube 106, and the fourth air tube 306, and then flow through the piston tube 303 and the bellows 304 before finally entering the oxygen mask 305. 5. The oxygen mask 305 is provided to the driver for rapid relief of oxygen deficiency discomfort. Simultaneously, because the annular cover tube 301 is installed on the outer surface of the annular tube 106 with a damped sealing rotation, the driver can adjust the position of the oxygen mask 305 according to their seating posture and oxygenation habits, improving oxygenation comfort. When the driver's oxygen deficiency symptoms are relieved and continued oxygenation is no longer necessary, the oxygen mask 305 can be released, and the spring 307 returns to its elastic deformation. This, through the ring 308, pulls the piston tube 303 upwards again within the sealing tube 302, resealing the opening of the fourth air tube 306. The oxygenation mechanism 3 then returns to standby mode, awaiting its next use.

[0029] In summary: By monitoring the oxygen concentration in the cabin in real time through oxygen sensors and automatically adjusting the oxygen supply with the controller, the risk of altitude sickness such as headaches and sudden drops in blood oxygen caused by hypoxia can be prevented from the root, reducing the risk of cardiopulmonary damage. At the same time, the emergency oxygen inhalation mechanism 3 can quickly provide high-concentration oxygen by pulling down the mask, providing an immediate relief solution for sudden hypoxia symptoms, thus providing dual protection for the driver's life and health and concentration during operation.
