Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of spray machine detection, and particularly relates to a spray machine mobile detection platform and a running control method thereof. BACKGROUND

[0002] In the performance test (including wind speed, wind pressure test and maximum range test) of a wind cylinder type spray machine (such as the sprayer / spray machine disclosed in CN201310349005.0 and CN201610048391.3), the to-be-tested spray machine needs to be pre-assembled and then transferred to the test environment by forklift or hoisting. Due to environmental factors, the to-be-tested spray machine needs to be transferred or adjusted in position again or multiple times according to the actual environmental conditions during the test. The water supply, power supply and parameter detection device also need to be transferred or disassembled at the same time during the transfer, which brings a great workload to the test personnel and leads to a very low efficiency. Moreover, the power forms of the spray machine include electric and hydraulic and other forms, and different power forms need to be matched with corresponding power sources, which leads to the need of preparing different power equipment such as generators / hydraulic pump stations in the test site, a large investment in test basic equipment, high cost and complex on-site management.

[0003] In addition, the wind pressure / speed needs to be collected at multiple positions according to different range spray machines during the test. The test personnel need to hold the collection equipment and measure and read data multiple times according to the distance points measured in advance, and the personnel need to withstand strong wind for a long time, which is a poor test environment for the personnel and is not conducive to the professional health of the test personnel. Due to the need of spray machine test, most test sites are in an open or semi-open state, and the test personnel also need to work in a relatively poor environment (such as severe cold, scorching heat, cold wind, etc.) before the test, which is also not conducive to the professional health of the test personnel. Moreover, during the test of the spray machine, if there are foreign matters or mechanical parts damaged in the spray machine wind cylinder are thrown out of the air port, the test personnel will also be subjected to mechanical impact during the test, which is a safety risk.

It should be noted that the generator 3 and the hydraulic pump station 8 are indirect power sources, both are power conversion devices, and need to be driven by external force to rotate to output the converted power. The external force is the vehicle engine. The power take-off 11 is a gear box connected to the output shaft of the vehicle engine, which is converted into two output interfaces. In the present application, the generator 3 and the hydraulic pump station 8 are coaxially connected, that is, the shafts of the two are connected in series to realize coaxial rotation. The generator 3 stops working by disconnecting the excitation control (which is a conventional means in the art), and the hydraulic pump station 8 also realizes no power output by connecting the inlet and return ports through the valve (which is a conventional means in the art). By controlling whether to start through the periphery, the generator 1 and the hydraulic pump station 8 can work simultaneously or separately.

The specific driving of the vehicle by the engine and the wheel transmission system is a prior art, which will not be described in detail here.

[0041] As shown in Figure 1As shown, in another preferred embodiment, an operation control room 5 is also installed on the carrier vehicle, the operation control room 5 is located at the front side of the mounting platform 6 at the tail end of the carrier vehicle, the environmental parameter detector 4 is installed on the top of the operation control room 5, the signal output ends of the environmental parameter detector 4 and the airflow parameter detector 124 are respectively connected with the environmental parameter input end and the airflow parameter input end of the operation control room 5.

[0043] The process of testing the spray machine using the present application is as follows: after sufficient fuel, hydraulic oil and dust suppression liquid are added to the mobile test platform, the spray machine to be tested is installed on the mounting platform 6 at the rear of the carrier vehicle, the spray machine is connected with the power pipeline (electrically connected with the power line, hydraulically connected with the hydraulic pipeline), the dust suppression liquid pipeline and the signal collection line, the connection mode of each pipeline, pipeline and line is common sense in the art, which is not described here; then the mobile test platform is moved to the test site by running the carrier vehicle on the ground. According to the environmental wind direction and wind force size detected by the environmental parameter detector 4, the spray machine nozzle (i.e. the air outlet of the spray machine air duct) is selected to face (the selection principle is not against the wind, and is not affected by the cross wind).

[0044] The power output form of the mobile detection platform is selected according to the type of the power of the spraying machine (usually AC 50Hz, AC 60Hz, DC 450-750V, hydraulic). Taking AC 50Hz as an example, the power generation parameters of the generator 3 are adjusted to the corresponding settings of 50Hz, the carrier vehicle engine is started, and the power take-off 11 is operated to transmit power from the generator to the generator 3. When the generator 3 generates normal voltage, the external power supply switch is closed to supply power to the power receiving interface of the spraying machine to be tested. At this point, the power supply of the spraying machine is completed.

[0045] The next step starts the test process of the spraying machine to be tested. First, the related parameters are set, the spraying machine is operated, and the initial diagnosis is made to determine whether there is any abnormal condition. After the initial diagnosis, the spraying machine is started and operated for a short time. Check whether the operation parameters of the signal acquisition system of the operation control room 5 are within the normal range. If it deviates from the normal, check the corresponding mechanical parts or parameter settings. After the operation without abnormality, the environmental parameter detector 4 starts to measure (acquire data in the meter or terminal) the environmental parameters: temperature, humidity, air pressure, wind speed, and wind direction and records them. Then, the voltages, currents, powers, and power factors of the fan, water pump, and auxiliary action motor of the spraying machine are measured. The fan barrel is operated to perform three full strokes of the pitch action, and the maximum and minimum currents, voltages, maximum working pressures of the hydraulic cylinder (if any), stroke speed, maximum pitch angle value, and maximum pitch angle value of the fan barrel are measured during each stroke. The fan barrel is operated to perform three full strokes of the swing action, and the maximum and minimum currents, voltages, maximum working pressures of the hydraulic motor (if any), output shaft speed, maximum right stroke angle value, and maximum left stroke angle value of the fan barrel are measured during each stroke.

[0046] The spraying machine fan barrel is restored to the middle position, the water pump and auxiliary action motor of the spraying machine are turned off, and the fan of the spraying machine is kept running. The robot storage rack 13 is expanded to extend the mobile collection robot 12 outside the carrier vehicle chassis 7, the mobile collection robot 12 is started, and the mobile collection robot 12 is extended out of the storage box body 131 to the ground. According to the relative coordinate position, the mobile collection robot 12 is automatically driven to the fan outlet, the folding lifting bracket 123 is operated to make the vertical axis center line of the airflow parameter detector flush with the cross section of the fan outlet, and the point is determined as the zero point (i.e. the circle point).

[0047] Combining Figure 2 and Figure 5As shown, the mobile collection robot 12 travels along the axis of the spray machine 14 nozzle to 10 meters at the A1 point, starts the airflow parameter detector 124, detects (wind speed and wind pressure can be measured simultaneously, or only one can be measured) for more than 5 seconds, each interval time is not less than 10 seconds, continuously detects three times and records the average value and the maximum value; the mobile collection robot 12 carries the airflow parameter detector 124 along the same radius arc line to the left of the A1 point and simultaneously monitors the wind speed without interruption, the airflow parameter detector 124 reciprocatingly moves at the maximum wind speed point recorded as A2, and then continuously detects three times with the A1 point detection step and records the data; the mobile collection robot 12 carries the airflow parameter detector 124 along the same radius arc line to the right of the A1 point, starts the uninterrupted monitoring of the wind speed after passing the axis, and the airflow parameter detector 124 reciprocatingly moves at the maximum wind speed point recorded as A3, and then continuously detects three times with the A1 point detection step and records the data. The mobile collection robot 12 carries the airflow parameter detector 124 back to the axis and then travels 10 meters, and finds B1, B2, B3, C1, C2, C3 as described above, and collects and records three times of data at each point with the A1 point detection step. When the mobile collection robot 12 carrying the airflow parameter detector 124 moves to the N point, the MAX[N1, N2, N3] minus the environmental wind speed is greater than 2 m / s, the mobile collection robot 12 carrying the airflow parameter detector 124 moves along the axis to the far end again, and when the MAX[N1, N2, N3] minus the environmental wind speed is less than 2 m / s, it moves to the near end in the opposite direction, and this reciprocation is repeated multiple times (such as three times), to find the position point where the MAX[N1, N2, N3] minus the environmental wind speed is equal to 2 m / s, which is the maximum range of the spray machine 14, and the straight-line length from the nozzle of the spray machine 14 is recorded.

[0048] The collected data is sorted to generate a report, and the test is completed.

[0049] Because the fan blowing of the spray machine is affected by the environment and is not coaxial with the air outlet of the wind cylinder, the mobile collection robot 12 needs to move left and right to find the maximum point (MAX[N1, N2, N3]) to determine the maximum range of the spray machine.

[0065]

[0066] wherein k is the adjustment coefficient, which is determined according to experiments, C a C is the target haze concentration reached by dust removal, v max v is the maximum allowable spraying speed.
