An embodiment of the present invention provides a cab rollover testing method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the cab rollover testing method according to the present invention.
In this embodiment, the cab rollover test method includes the following steps:
step S10: when a cab turnover test request is received, a limit signal is acquired through a limit sensor.
It should be noted that the main executing body of the method of this embodiment may be a device having data transmission, data acquisition, and data processing functions, for example: the turning test device may also be other devices that can implement the same or similar functions, and this embodiment does not specifically limit this.

In a specific implementation, referring to fig. 3, 4, 5, and 6, a schematic perspective structure diagram, a schematic top view diagram, a schematic left view diagram, and a schematic front view diagram of the flip test apparatus are shown in sequence.
It should be understood that, in the present embodiment, the limit sensors are divided into an upper limit sensor and a lower limit sensor, and are used for detecting the current position of the cab, so that the PLC controller controls the cab to perform the turning operation according to the current position of the cab.
In the concrete implementation, if the cab is in a normal state, namely in a non-turnover state, only the lower limit sensor can acquire the lower limit signal, and at the moment, the turnover operation of the cab can be the lifting operation of a hydraulic pump or an electric pump for controlling the cab so as to lift the cab; similarly, if the cab is at the highest point, the cab does not need to be lifted at the moment, and the cab is turned over to control the hydraulic pump or the electric pump to descend; the present embodiment does not specifically limit this.
In addition, if the upper limit sensor and the lower limit sensor do not acquire corresponding limit signals, the cab is in a middle state of a lowest point and a highest point, and the cab can be controlled to fall firstly and then the limit signals are judged again in order to facilitate the overturning test.
In a specific implementation process, after receiving a cab rollover test request, a power supply or a switch in the rollover test device may be started, and the rollover test device and the cab are reset, where the reset process may be to adjust a position of a lifting handle of the rollover test device or adjust an opening and closing state of an electromagnetic valve, and the reset of the cab may be to control a position of the cab to be at a highest point or a lowest point, which is not specifically limited in this embodiment.
Step S20: and adjusting the position of the lifting handle according to the limit signal.
It should be noted that, the adjusting of the position of the lifting handle according to the limit signal may be that when a lower limit signal is detected, the PLC controls the solenoid valve to open, and the blowing cylinder to open, so as to realize motion control of the cylinder, and thus drive the lifting handle to move to a position where the cab can be lifted.
Step S30: and generating a turning instruction according to the position of the lifting handle after adjustment, and outputting the turning instruction to a cab so as to turn the cab according to a preset turning strategy according to the turning instruction.
It should be noted that, after the position adjusted by the lifting handle reaches the adjustment position corresponding to the collected limit signal, the PLC controller generates a tilting instruction, and sends the tilting instruction to the electric pump or the hydraulic pump in the cab to perform a lifting operation.
It is understood that the preset overturning strategy may be a strategy for controlling the lifting or dropping of the electric pump of the cab according to the collected limit signal, such as: when the cab needs to be lifted, the cab can be lifted to the highest point and then stays for 15 seconds, the situation that the temperature of the electric pump is too high and the equipment is damaged is avoided, and after the staying time is over, the device is controlled to reversely rotate through the electromagnetic valve, the air cylinder, the blowing cylinder, the electric pump of the cab and the like so as to change the overturning direction, and therefore the cab can fall back.
The embodiment discloses a cab turning test method, which is applied to turning test equipment, wherein the turning test equipment comprises: the device comprises a limiting sensor and a lifting handle, wherein the limiting sensor is used for determining the relative connection position of a cab and the overturning test equipment and acquiring a limiting signal of the relative connection position, and the lifting handle is used for controlling the cab to overturn; the cab turnover testing method comprises the following steps: when a cab turning test request is received, acquiring a limit signal through a limit sensor; adjusting the position of the lifting handle according to the limit signal; according to position generation upset instruction after lifting handle adjustment, and output upset instruction to driver's cabin, so that the driver's cabin basis the upset instruction is according to predetermineeing the upset strategy and is overturn, and this embodiment is through the position of the spacing signal control lifting handle that control among the upset test equipment spacing sensor gathered, can be accurate according to the position generation corresponding upset instruction of driver's cabin, through will upset instruction is sent to the driver's cabin, and the driver's cabin of being convenient for can be according to the upset strategy that upset instruction corresponds carries out the upset test, has avoided among the prior art to vehicle driver's cabin lifting system's durability test, complex operation's technical problem, has improved the precision and the efficiency of upset test.
Referring to fig. 7, fig. 7 is a flowchart illustrating a cab-rollover testing method according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, after the step S30, the method further includes:
step S40: and receiving the real-time overturning position fed back by the cab.
It should be noted that the real-time turning position may be determined by detecting a lifting distance of the electric pump or the hydraulic pump detected by the on-board controller inside the cab, and may also be measured by a sensor in the turning test apparatus provided in this embodiment, which is not limited in this embodiment.
Step S50: and when the real-time overturning position reaches a preset overturning position, unlocking the electromagnetic valve.
It should be noted that the preset turning position refers to the highest point of the cab which rises or the lowest point of the cab which falls.
Wherein, according to the upset direction difference, the selection of predetermineeing the upset position is also different, for example: when the cab is lifted and turned, the preset turning position is the highest point of the lifting of the cab; when the cab falls and overturns, the preset overturning position is the lowest point of the descending of the cab.
It should be noted that, in the process of overturning the cab, in order to protect the safety of each device of the vehicle where the cab is located, after the electric pump is lifted to the highest point, the electromagnetic valve is locked to prevent the air cylinder from being continuously inflated by the influence of the blowing cylinder, so that the pressure is increased, and further the cab is controlled to be continuously lifted and overturned.
Therefore, when the overturning direction of the cab needs to be changed, the electromagnetic valve can be unlocked firstly, so that the cab can be controlled to fall back in the following process.
Further, if the real-time turning position does not reach the preset turning position, it indicates that a fault exists in the turning test process, and therefore, after receiving the real-time turning position fed back by the cab, the method further includes:
when the real-time overturning position does not reach a preset overturning position, controlling the air cylinder and the electromagnetic valve to stop running;
and generating a turning stopping instruction, and sending the turning stopping instruction to the cab to control the electric pump in the cab to stop working.
It should be noted that the preset turning position is determined according to the turning direction of the cab, for example: if the overturning direction of the cab is ascending and overturning, the preset overturning position is the highest point of the cab; the overturning direction of the cab is falling and overturning, and the preset overturning position is the lowest point of the cab.
In addition, after the generating and sending the instruction to the cab to control the electric pump in the cab to stop working, the method further includes:
the second time length is preset at intervals, and the air cylinder is controlled to move in the second direction for a preset third time length;
and adjusting the position of the lifting handle to enable the cab to perform descending and overturning operations.
It should be understood that the preset second duration may be a time interval slightly shorter than the preset first duration, for example: the preset first time is 15s, and the preset second time can be 10s, because the running time of the electric pump in the working process is shorter than the time of normally running to the preset overturning position, the heat dissipation time can be relatively shorter, and the overturning testing efficiency is improved.
In addition, the preset third time length can be longer than the preset first time length, so that the situation that the electric pump cannot reset due to equipment damage is avoided, and the fault source can be determined according to the resetting condition of the electric pump.
Step S60: after the interval presets first duration, control the cylinder removes based on the second direction, in order to adjust lift the position of handle, until spacing sensor gathers the last limit signal.
It will be appreciated that the preset first duration may be due to a self-set time interval, such as: and 15 seconds, the electric pump or the hydraulic pump used for cooling the cab is used for preventing the temperature rise of the electric pump or the hydraulic pump from being too high, and the equipment is prevented from being damaged.
In this embodiment, the first direction is opposite to the second direction, and therefore the position of the adjustment lifting handle is also opposite in space, for example: the control cylinder moves based on the first direction to lower the lifting handle, and then the control cylinder moves based on the second direction to raise the lifting handle, which is not limited in this embodiment.
In the specific implementation, because the lower limit signal is collected firstly in the overturning test process, and the cab is controlled to ascend and overturn, after one ascending and overturning is completed, the cab needs to be controlled to descend and overturn so as to realize the complete overturning test in sequence.
Further, in order to accurately record the information of the number of times of the roll-over test, after step S60, the method further includes:
updating the turnover frequency of the cab;
and when the updated overturning times are not less than the preset overturning times, controlling the air cylinder and the electromagnetic valve to reset.
It is understood that the preset turning number may be 10 times, and the embodiment is not limited in this respect.
It should be understood that after the cab is turned over for the preset number of times, the devices such as the air cylinder and the electromagnetic valve in the turning test equipment can be reset to the state before the turning test, so that the next turning test is performed, or the turning test is performed for the next vehicle.
The embodiment discloses receiving a real-time rollover position fed back by the cab; when the real-time overturning position reaches a preset overturning position, unlocking the electromagnetic valve; after the interval presets first time length, control the cylinder removes based on the second direction, in order to adjust lift the position of handle, until spacing signal is gathered to spacing sensor, this embodiment is through after accomplishing the ascending upset of a folk prescription, moving based on the second direction through control cylinder, in order to adjust lift the position of handle, until spacing signal is gathered to spacing sensor, reentrant the ascending upset test in another side, once complete test procedure has been accomplished to survey the upset performance of whole car driver's cabin.
Referring to fig. 8, fig. 8 is a schematic flow chart of a cab-rollover testing method according to a third embodiment of the present invention.
Based on the second embodiment, in this embodiment, the step S20 includes:
step S201: when the limit signal is a lower limit signal, the control cylinder moves based on a first direction to lift the position of the lifting handle.
Step S202: and when the limit signal is an upper limit signal, the control cylinder moves based on a second direction so as to lower the position of the lifting handle.
It should be noted that, when the cab is subjected to the rollover test, if the initial state of the cab is in a normal state, that is, in a no-rollover state, only the lower limit sensor can acquire the lower limit signal, and the upper limit sensor cannot acquire the upper limit signal, at this time, the rollover operation on the cab may be to control a hydraulic pump or an electric pump of the cab to perform lifting operation, so as to lift the cab; similarly, if the cab is at the highest point, the cab does not need to be lifted at the moment, and the cab is turned over to control the hydraulic pump or the electric pump to descend; the present embodiment does not specifically limit this.
In addition, if the upper limit sensor and the lower limit sensor do not acquire corresponding limit signals, the cab is in a middle state of a lowest point and a highest point, and the cab can be controlled to fall firstly and then the limit signals are judged again in order to facilitate the overturning test.
Further, after the position of the lifting handle is adjusted, the method further comprises the following steps:
acquiring the position of the cylinder;
and when the position of the air cylinder is at a preset first air cylinder position or a preset second air cylinder position, locking the electromagnetic valve.
In concrete realization, in the driver's cabin upset in-process, in order to protect the safety of each equipment of driver's cabin place vehicle, after the electric pump rises to the peak, through locking the solenoid valve, in order to avoid the cylinder to continue to receive the influence of section of thick bamboo of blowing to aerify, lead to the pressure grow, and then control the driver's cabin and continue to rise the upset, can also prevent to lead to the cylinder pressure to reduce because equipment damages or environmental impact, control the driver's cabin to fall back on the contrary, but because the effect of section of thick bamboo of blowing, can lead to the electric pump of driver's cabin to overturn repeatedly, cause the temperature rise too big, damage equipment.
The motion direction of the air cylinder is determined through the type of the limiting signal, so that the lifting handle is lifted and turned or falls back and turned, the position of the lifting handle is adjusted, the operation steps of a turning test are reduced, and the operation process is simplified.
In addition, an embodiment of the present invention further provides a storage medium, where the storage medium stores a cab-rollover test program, and the cab-rollover test program implements the steps of the cab-rollover test method described above when executed by a processor.
Since the storage medium adopts all technical solutions of all the embodiments, at least all the beneficial effects brought by the technical solutions of the embodiments are achieved, and no further description is given here.
