Description

Technical Field

[0001] The invention relates to the technical field of automatic cleaning, and in particular to a low-power vehicle side automatic cleaning system based on compressed air. Background Art

[0002] According to the relevant provisions of the "Railway Freight Transport Management Rules" on cargo loading safety, when using open cars to load loose cargo, the residues on the side of the open car, the hooks, and the hand brake platform must be cleaned up, otherwise the station will not transport it; and the residues on the side of the car are likely to cause the residues to splash, causing certain environmental pollution to the environment along the line. In addition, if a train is dispatched with floating coal on the side of the car, the railway bureau will impose heavy penalties on the coal mine and the dispatching station. In serious cases, the dispatch plan will be reduced and the commercial coal shipment will be stopped.

[0003] At present, most loading stations use manual cleaning to deal with coal accumulation on the side of the train. The manual cleaning process is complicated. For each carriage to be cleaned, the personnel need to get on and off the carriage twice. After cleaning one carriage, the train must start and drive the other carriage to a non-electric area before cleaning the carriage. Therefore, the cleaning personnel need to spend a lot of time cleaning, which increases the loading time and affects the loading efficiency and the efficiency of subsequent train entry. The disadvantages of this cleaning method are not only the high labor intensity and low work efficiency of the cleaning personnel, but also the safety hazards of falling from heights and electric shock.

[0004] At present, a few loading stations use automatic devices to clean the side of the train to deal with coal accumulation. This device mostly uses brushes to clean the coal on the front and rear sides of the carriage. Due to the relative movement between the side of the carriage and the cleaning mechanism, the brushes will be bent forward by the side of the carriage, and the cleaning effect will deteriorate after long-term operation. The brushes need to be replaced if there is no obvious wear. In addition, this type of device has the disadvantage of high energy consumption. For carriages that do not need to be cleaned, the device will still perform cleaning actions indiscriminately.

[0005] Based on the above technical problems, the present invention provides a low-power vehicle side automatic cleaning system based on compressed air. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 2 The present invention provides a low-power vehicle side automatic cleaning system based on compressed air, comprising:

[0033] A main frame 5, a rail 1 passes through the main frame 5, and a transport carriage 2 is arranged on the rail 1;

[0034] The first purge mechanism 3 is provided with two groups, and the two groups of the first purge mechanisms 3 are symmetrically mounted on opposite sides of the main support 5. The first purge mechanism 3 includes a height adjustment component, a first angle adjustment component and a first purge component. The height adjustment component is mounted on the main support 5, the first angle adjustment component is mounted on the height adjustment component, and the first purge component is mounted on the first angle adjustment component;

[0035] The second purge mechanism is vertically mounted at the middle position of the top of the main support 5. The second purge mechanism includes a lifting assembly 6, a second angle adjustment assembly and a second purge assembly 7. The lifting assembly 6 is vertically mounted on the main support 5. The second purge assembly 7 is mounted on the lifting assembly 6 through the second angle adjustment assembly.

[0036] A height measuring unit, which is arranged in front of the main support 5 and located on two opposite sides of the rail 1;

[0037] The terminal system, the height measuring unit, the height adjusting component, the first angle adjusting component, the first purge component, the lifting component 6, the second angle adjusting component and the second purge component 7 are all connected to the terminal system signal.

[0038] The terminal system uses a low-power MSP430 microcontroller with a power supply voltage of DC1.8-3.6V. Therefore, when it runs under a 1MHz clock condition, the chip current is as low as 165μA, and the lowest power consumption in RAM retention mode is only 0.1μA. The microcontroller has five low-power modes, namely LPM0~LPM4 (LOW POWER MODE). The active state of the CPU is called AM (ACTIVE MODE) mode, among which AM mode consumes the most power and LPM4 mode consumes the least power, only 0.1μA. Usually, the CPU is in a dormant low-power state. From this low-power mode, it is awakened to the active state by using its external interrupt form. The external interrupt signal is the level output signal of the active railway wheel sensor 9.

[0039] When a train passes, the awakened MSP430 microcontroller records the height value detected by its grating, and compares it with the height of the coal car compartment of the train loaded with coal in the maintenance record read from the "Coal Car Management System". If it is not greater than 1.2 times the highest car, it is considered to be a coal car compartment. At this time, device 1 (the front and rear edge blowing device on the top of the car) should be lowered to the height of the car just detected; if it is not less than 1.5 times the highest car, it is considered to be the front of the train and no lowering or cleaning is performed.

[0040] After the grating detection device detects the coal car compartment, the single-chip control system reads the running speed v of the coal car compartment in the "coal transport car management system", and waits for the dropping funnel to drop the coal into the compartment, and the cleaning device starts working.

[0041] A further optimized solution is that the height adjustment component includes a wind knife bracket 4 fixedly connected to the main bracket 5, a vertical hoist 307 and a lifting motor 308 are installed on the wind knife bracket 4, the lifting motor 308 and the vertical hoist 307 are coordinated in transmission, a cantilever support frame 306 is installed on the vertical hoist 307, and the first angle adjustment component is installed on the cantilever support frame 306.

[0042] A further optimized solution is that the first angle adjustment component includes a horizontal rotating arm 304, which is rotatably connected to the end of the cantilever support frame 306, and a horizontal rotating motor 305 is fixedly connected to the horizontal rotating arm 304, and the output shaft of the horizontal rotating motor 305 is fixedly connected to the cantilever support frame 306.

[0043] According to a further optimized solution, the first purge assembly includes a first mounting plate 302 fixedly connected to the end of a horizontal rotating arm 304, and a plurality of first nozzles 301 are arranged on the second mounting plate. Solenoid valves 303 are respectively installed at the ports of the first nozzles 301, and the solenoid valves 303 are connected to the gas source through a pipeline.

[0044] According to a further optimized solution, the height adjustment component includes a hydraulic telescopic rod, which is vertically fixedly connected to the middle position of the main support 5, and the second angle adjustment component is installed at the end of the hydraulic telescopic rod.

[0045] According to a further optimized solution, the second angle adjustment component includes an angle adjustment motor, and the angle adjustment motor is installed at the bottom end of the hydraulic telescopic rod.

[0046] According to a further optimized solution, the second purge assembly 7 includes a second mounting plate fixed on the output shaft of the angle adjustment motor, and a plurality of groups of second nozzles are evenly spacedly mounted on the second mounting plate, and the second nozzles are connected to the gas source via a delivery pipe.

[0047] First, adjust the direction of the second purge component 7 according to whether it is at the front or rear edge of the carriage, that is, the direction of the wind knife is backward when it is at the front edge, and the direction of the wind knife rotates 180° when it is at the rear edge, to ensure that the fallen coal at the front and rear edges of the carriage can be blown into the carriage; according to the relative position of the second purge component 7 and the carriage, adjust the angle of the second purge component 7 in real time to ensure that the compressed air from the second nozzle can blow the fallen coal into the carriage. The angle of the second nozzle is ±15°, that is, when the grating starts to detect the arrival of the carriage, control the horizontal rotating motor 305 to rotate so that the angle of the second nozzle is adjusted to -15°, and then gradually control the motor rotation at the running speed v of the carriage to change the angle of the second nozzle. When passing the rear end of the carriage, the angle of the second nozzle is adjusted to +15°. In this process, the compressed air valve of the cleaning device is opened according to the amount of coal falling on the side of the car. The compressed air valve of device 2 has 9 valves, 3×3, evenly distributed.

[0048] Further optimization scheme, the height measurement unit includes a measuring grating 8, and the measuring grating 8 is provided with two groups, and the two groups of measuring gratings 8 are symmetrically fixed on both sides of the rail 1, and the measuring grating 8 is located in front of the main support 5. The thickness of the falling coal is measured by the SMTC type measuring grating 8, the model is SMTCA080592-4N00, the optical axis spacing is 8mm, RS485 output, and the measuring height is 592mm.

[0049] According to a further optimized solution, a wheel sensor 9 is installed on the rail 1 .

[0050] When the height measured by the measuring grating 8 is consistent with the height of the carriage, it is considered that there is no coal falling from the coal wall, and no coal blowing and cleaning is carried out; when the difference between the height measured by the measuring grating 8 and the height of the carriage is 0 < D ≤ 10 mm, a group of nozzles at the corresponding position is opened to blow and spray the fallen coal into the coal car; when the difference between the height measured by the measuring grating 8 and the height of the carriage is 10 < D < 20 mm, two groups of nozzles at the corresponding position are opened to blow and spray the fallen coal into the coal car; when D ≥ 20 mm, three groups of nozzles at the corresponding position are opened to blow and spray the fallen coal into the coal car.
