It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

In addition, in the description of the present disclosure, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or order. Similarly, although operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In some cases, multitasking and parallel processing may be advantageous.

As shown in fig. 1, the inspection apparatus includes a plurality of components including a hoisting mechanism 100, a hydraulic power system 110, a tension sensor 120, a man-machine interaction system 130, and a control system 140.

The hoist mechanism 100 includes at least one of a first hoist mechanism configured to be coupled to a work platform of the work vehicle via a first rope and a second hoist mechanism (neither shown) configured to be coupled to a boom of the work vehicle via a second rope. Here, the work platform is connected with one end of the boom, which is far away from the body of the work vehicle. In some embodiments, the work vehicle may be a fire truck, such as a lifting fire truck.

As some embodiments, the first hoisting mechanism may be a hoisting machine with a mass of 3 tons and a maximum length of 50 meters corresponding to the maximum pulling force; the second hoisting mechanism may be a hoisting machine having a mass corresponding to the maximum pulling force of 1 ton and a maximum length of the second rope of 100 meters. The first hoisting mechanism and the second hoisting mechanism can respectively comprise a winding drum, a bracket, a hoisting speed reducer, a hydraulic motor and the like.

The hydraulic power system 110 is configured to drive the hoisting mechanism 100. The hydraulic power system 110 is configured to drive at least one of the first hoisting mechanism and the second hoisting mechanism.

The tension sensor 120 includes at least one of a first tension sensor configured to measure a tension of the first rope and a second tension sensor (neither shown) configured to measure a tension of the second rope.

The human-machine interaction system 130 is configured to receive at least one of a first preset tension value for the first rope and a second preset tension value for the second rope entered by a user. For example, the user may input only a first preset tension value, or only a second preset tension value, or both the first preset tension value and the second preset tension value.

As some embodiments, the man-machine interaction system 130 may include an industrial personal computer, a display, an operation handle, and a selection button. Here, the industrial personal computer may be provided with pre-compiled upper computer operation software, so that display, monitoring and storage of the process variable (e.g., tension of the rope) may be realized. As some embodiments, the man-machine interaction system 130 has a convenient man-machine interaction interface, and is simple to operate.

The control system 140 is configured to control the hydraulic power system 110 to drive the hoisting mechanism 100 such that at least one of the first condition and the second condition is satisfied. Here, the first condition is that the tension of the first rope measured by the first tension sensor is equal to a first preset tension value, and the second condition is that the tension of the second rope measured by the second tension sensor is equal to a second preset tension value. As some embodiments, the control system 140 controls the hoisting mechanism 100 to stop hoisting in case at least one of the first condition and the second condition is satisfied.

Because the operation vehicle can work in various working scenes, the arm support also has various bearing scenes. The related art can only artificially simulate a load-bearing scene of an arm support (a scene of vertically hanging a heavy object on a working platform), so that the safety of the working vehicle cannot be accurately detected.

In some embodiments, the detection device is configured to be movable to change an angle between at least one of the first and second ropes and a horizontal plane to simulate at least one of a plurality of operational scenarios of the boom. It should be understood that the level is the ground on which the work vehicle is located.

On the one hand, the movable detection equipment can simulate the bearing scenes of various arm frames by moving, so that the safety of the operation vehicle is accurately detected; on the other hand, the transfer of different test sites can be facilitated, so that the detection efficiency is improved.

Next, an operational schematic of a detection apparatus according to some embodiments of the present disclosure will be described with reference to fig. 2 to 4.

In some embodiments, as shown in fig. 2, the plurality of work scenarios includes a first work scenario, and the detection device is configured to move to the first position in a case where the first work scenario is simulated such that an angle between the first rope and an orthographic projection of the first rope on a horizontal plane is less than 90 degrees. Here, the first position is closer to the work vehicle than the position where the detection device is located with the first rope being perpendicular to the horizontal plane.

As some embodiments, the first working scenario may be, for example, a scenario in which the working platform of the working vehicle is subjected to a downward oblique force, for example, in which the working platform of the elevating fire truck is subjected to a reaction force of a water flow ejected by a fire monitor. In this case the boom will be subjected to a certain load.

In this way, when the man-machine interaction system 130 receives the first preset tension value for the first rope input by the user, the working platform of the working vehicle can be simulated to bear the inclined downward acting force, so that the safety of the working vehicle can be detected more accurately.

As further embodiments, as shown in fig. 3, the plurality of work scenarios includes a second work scenario, the detection device being configured to move to a position such that the first rope is perpendicular to the horizontal plane in case the second work scenario is simulated.

As some embodiments, the second working scenario may be, for example, a scenario in which the work platform of the work vehicle is subjected to a vertical downward force, e.g., a scenario in which the work platform is subjected to a different downward force if a different worker is located on the work platform. In this case the boom will be subjected to a certain load.

In this way, when the man-machine interaction system 130 receives the first preset tension value for the first rope input by the user, the working platform of the working vehicle can be simulated to bear the vertical downward acting force, so that the safety of the working vehicle can be detected more accurately.

As some implementations, the second working scenario may include, for example, two sub-scenarios: a first sub-scene of stable load exists in the working platform, and a second sub-scene of the working platform bearing impact load exists in the working platform. Here, the impact load may be, for example, an impact load when a worker enters the work platform.

Two sub-scenes in the second operation scene are respectively described below.

As some embodiments, the detection device is configured to move to a position such that the first rope is perpendicular to the horizontal plane in a case of simulating the first sub-scene, and to make the hoisting speed of the first hoisting mechanism a first speed less than or equal to the first preset speed.

It should be appreciated that the first preset speed may be set according to the actual situation. As some embodiments, the first preset speed may be a product of the first preset coefficient and a maximum hoisting speed of the first hoisting mechanism. For example, one half of the maximum hoisting speed of the first hoisting mechanism may be set to the first preset speed; for another example, one third of the maximum hoisting speed of the first hoisting mechanism may be set to the first preset speed.

In this way, under the condition that the man-machine interaction system 130 receives the first preset tension value for the first rope input by the user, the sub-scene with stable load in the working platform can be simulated at a slower hoisting speed, the possibility that the hoisting speed is too fast to additionally impact the arm support is reduced, and therefore different working scenes are simulated more accurately, and the safety of the working vehicle is detected further more accurately.

As further embodiments, the detection device is configured to move to a position such that the first rope is perpendicular to the horizontal plane in case of simulating the second sub-scene, and to bring the hoisting speed of the first hoisting mechanism to a second speed that is larger than the first preset speed.

In this way, when the man-machine interaction system 130 receives the first preset tension value for the first rope input by the user, the sub-scene of the impact load borne by the working platform can be simulated at a faster hoisting speed, so that different working scenes can be simulated more accurately, and the safety of the working vehicle can be detected further more accurately.

In other embodiments, as shown in fig. 4, the plurality of work scenarios includes a third work scenario, and the detection device is configured to move to the second position such that an angle between the second rope and an orthographic projection of the second rope on a horizontal plane is less than 90 degrees if the third work scenario is simulated. Here, the second position is farther from the work vehicle than the position where the detection device is located with the second rope being perpendicular to the horizontal plane.

As some embodiments, the third working scenario may be, for example, a scenario in which the boom of the work vehicle is subjected to a downward-tilting force.

In this way, when the man-machine interaction system 130 receives the second preset tension value for the second rope input by the user, the situation that the boom of the working vehicle bears the downward inclined acting force can be simulated, so that the safety of the working vehicle can be detected more accurately.

As some implementations, the third working scenario may include, for example, two sub-scenarios: a third sub-scene in which the arm support of the working vehicle bears the acting force of the back wind and a fourth sub-scene in which the arm support of the working vehicle bears the inertial load when suddenly stopped under the condition of downward movement. In both sub-scenes, the boom will bear a certain downward load.

Two sub-scenes in the third operation scene are respectively described below.

As some embodiments, the detection device is configured to make the hoisting speed of the second hoisting mechanism 102 a third speed less than or equal to the second preset speed in case of simulating the third sub-scene. Here, the setting of the second preset speed is similar to the setting of the first preset speed, and will not be described herein. The second preset speed may be the same as or different from the first preset speed. As some embodiments, the second preset speed may be a product of the second preset coefficient and a maximum hoisting speed of the second hoisting mechanism. For example, one half of the maximum hoisting speed of the second hoisting mechanism may be set to the second preset speed; for another example, one third of the maximum hoisting speed of the second hoisting mechanism may be set to the second preset speed.

In this way, when the man-machine interaction system 130 receives the second preset tension value for the second rope input by the user, the sub-scene that the arm support of the working vehicle bears the acting force of the back wind can be simulated at a slower hoisting speed, so that the possibility that the arm support is impacted excessively due to the too fast hoisting speed is reduced, and the safety of the working vehicle is further and more accurately detected.

As further embodiments, the detection device is configured to bring the hoisting speed of the second hoisting mechanism to a fourth speed that is greater than the second preset speed in case of simulating the fourth sub-scenario.

In this way, when the man-machine interaction system 130 receives the second preset tension value for the second rope input by the user, the sub-scene of the inertial load when the boom of the working vehicle suddenly stops under the condition of downward movement can be simulated at a faster hoisting speed, so that the safety of the working vehicle can be further and more accurately detected.

It should be understood that, according to the preset tension value input by the user, the detection device may simulate only one working scene, or may simulate a plurality of working scenes at the same time. For example, the detection device may simulate a first, second, or third operational scenario; for another example, the detection device may simulate the first and third operating scenarios simultaneously; for example, the detection device may simulate the second and third operating scenarios simultaneously.

In some embodiments, the second rope may be connected at a midpoint of the boom. Therefore, the stress condition of the arm support in the third working scene can be more accurately simulated, and the safety of the working vehicle can be more accurately detected.

In some embodiments, the detection device further comprises a chassis mechanism. Here, the chassis mechanism carries a plurality of components, and is configured to be movable to make the detection device movable. In this way, the detection device can be moved more conveniently through the chassis mechanism, thereby further improving the efficiency of detection.

As some embodiments, the chassis mechanism may be an electric flat car, as shown in fig. 5. For example, an electric flat car may include a frame, a speed reducer, a pair of drive wheels, a pair of driven wheels, a drive motor, an on-board control box, an audible and visual alarm, and the like. In some embodiments, the electric flat car may achieve a continuously variable speed, for example, at 5 to 20 meters per minute.

In some embodiments, the inspection apparatus further comprises at least one of a first inspection tool and a second inspection tool. Here, the first rope is configured to be connected with the work platform through the first detection tool, and the second rope is configured to be connected with the boom through the second detection tool.

Therefore, the detection tool matched with the detection equipment is connected with the working platform and the arm support, so that the connection between the detection equipment and the working platform or the arm support is firmer, and the falling-off condition of the rope during detection is reduced, and the detection efficiency and the reliability are improved.

In some embodiments, the first detection tool and/or the second detection tool may be a hook-like device to facilitate installation and removal. In this case, for example, one end of the first detection tool may be hooked on the bracket of the working platform, and the other end may be connected to the first rope; one end of the second detection tool can be sleeved on the arm support of the operation vehicle and can slide on the arm support to change the sleeved position, and the other end of the second detection tool can be connected with the second rope.

In the related art, the motor directly drives the winch has the problem of small torque, and the internal combustion engine is used for driving the hydraulic pump to increase the torque, but the speed regulation precision is poor.

The structure of the hydraulic power system 110 in the inspection apparatus proposed in the present disclosure will be described next in connection with some embodiments.

In some embodiments, the hydraulic power system 110 includes a flow valve, a hydraulic pump, and an electric motor. Here, the flow valve includes at least one of a first flow valve and a second flow valve, a hydraulic pump is connected to the flow valve, and an electric motor is connected to the hydraulic pump and configured to drive the hydraulic pump to push hydraulic oil into an oil inlet of the hydraulic power system 110 such that the hydraulic oil flows toward the flow valve to drive the hoist mechanism 100 to operate.

As shown in fig. 6, the first flow valve includes a first oil inlet, two first working oil ports, and a first oil return port. Here, the first oil inlet is connected with an oil inlet (i.e., P port) of the hydraulic power system 110, the two first working oil ports are connected with the first hoisting mechanism, and the first oil return port is connected with an oil return port (i.e., T port) of the hydraulic power system 110. Here, one of the two first working oil ports is configured to deliver hydraulic oil to the first hoisting mechanism, and the other is configured to receive hydraulic oil that flows back from the first hoisting mechanism.

As shown in fig. 7, the second flow valve includes a second oil inlet, two second working oil ports, and a second oil return port. Here, the second oil inlet is connected with the oil inlet of the hydraulic power system 110, the two second working oil ports are connected with the second hoisting mechanism, and the second oil return port is connected with the oil return port of the hydraulic power system 110. Here, one of the two second working oil ports is configured to deliver hydraulic oil to the second hoisting mechanism, and the other is configured to receive hydraulic oil that flows back from the second hoisting mechanism.

On the one hand, the problem of smaller torque in a motor direct-drive winch mode in the related art and the problem of poor speed regulation precision in a mode of driving the hydraulic pump by using an internal combustion engine can be solved by driving the hydraulic pump by the motor, so that hydraulic oil can be more accurately pushed to enter an oil inlet of the hydraulic power system 110; on the other hand, the hydraulic oil can be conveyed to the hoisting mechanism 100 through the flow valve, and the hydraulic oil reflowed from the hoisting mechanism 100 is received, so that the hoisting of the hoisting mechanism 100 is controlled more accurately, different working scenes of the arm support are simulated more accurately, and the safety of the operation vehicle is detected more accurately.

In some embodiments, the detection apparatus further comprises at least one of the first set of relief valves and the second set of relief valves.

The first and second sets of relief valves are described next in connection with fig. 8 and 9.

As shown in fig. 8, the first group of relief valves includes at least one of a first relief valve connected between one of the two first working ports and the return port of the hydraulic power system 110 and a second relief valve connected between the other of the two first working ports and the return port of the hydraulic power system 110.

As shown in fig. 9, the second group of relief valves includes at least one of a third relief valve connected between one of the two second working ports and the return port of the hydraulic power system 110 and a fourth relief valve connected between the other of the two second working ports and the return port of the hydraulic power system 110.

As some embodiments, in the case where the oil pressure of the working port that delivers the hydraulic oil to the first hoisting mechanism exceeds the first preset threshold, the corresponding relief valve may divert a portion of the hydraulic oil so that the oil pressure is less than or equal to the first preset threshold; as other embodiments, in the case where the oil pressure of the working port that delivers the hydraulic oil to the second hoisting mechanism exceeds the second preset threshold, the corresponding relief valve may divert a portion of the hydraulic oil so that the oil pressure is less than or equal to the second preset threshold. It should be understood that the first preset threshold and the second preset threshold may be set according to actual needs.

Thus, hydraulic oil can be stably supplied to the hoisting mechanism 100 by the diversion action of the relief valve, and further, the hoisting of the hoisting mechanism 100 can be more precisely controlled, thereby further more precisely detecting the safety of the working vehicle.

In some embodiments, the detection apparatus further comprises at least one of the first set of solenoid valves and the second set of solenoid valves. The first group of electromagnetic valves is connected with the first flow valve, the second group of electromagnetic valves is connected with the second flow valve, the first group of electromagnetic valves comprises a first electromagnetic valve and a second electromagnetic valve, and the second group of electromagnetic valves comprises a third electromagnetic valve and a fourth electromagnetic valve.

Here, the first group of solenoid valves is configured to control a flow direction of hydraulic oil of the first flow valve to change a rotation direction of the spool of the first hoisting mechanism, and the second group of solenoid valves is configured to control a flow direction of hydraulic oil of the second flow valve to change a rotation direction of the spool of the second hoisting mechanism.

As some embodiments, the first solenoid valve may control an operation state of one of the two first operation ports, and the second solenoid valve may control an operation state of the other first operation port. For example, when the first solenoid valve is energized, the first hydraulic oil port corresponding to the first solenoid valve is unable to deliver hydraulic oil to the first hoisting mechanism; when the first solenoid valve is not energized, the first working oil port corresponding to the first solenoid valve may deliver hydraulic oil to the first hoisting mechanism. For another example, when the second solenoid valve is energized, the first hydraulic oil port corresponding to the second solenoid valve cannot deliver hydraulic oil to the first hoisting mechanism; when the second electromagnetic valve is not electrified, the first working oil port corresponding to the second electromagnetic valve can convey hydraulic oil to the first hoisting mechanism.

As some embodiments, the cooperative operation of the first solenoid valve and the second solenoid valve may control the flow direction of the hydraulic oil of the first flow valve to change the rotation direction of the spool of the first hoisting mechanism.

For example, when the first solenoid valve is not energized and the second solenoid valve is energized, hydraulic oil flows from a first work oil port corresponding to the first solenoid valve to the first hoisting mechanism, and the first work oil port corresponding to the second solenoid valve receives hydraulic oil that flows back from the first hoisting mechanism; for another example, when the first solenoid valve is energized and the second solenoid valve is not energized, hydraulic oil flows from the first hydraulic fluid port corresponding to the second solenoid valve to the first hoisting mechanism, and the first hydraulic fluid port corresponding to the first solenoid valve receives the hydraulic oil that flows back from the first hoisting mechanism; also, for example, in the case where both the first solenoid valve and the second solenoid valve are energized, hydraulic oil cannot flow to the first hoisting mechanism.

It should be understood that the third solenoid valve and the fourth solenoid valve operate in a similar manner to the first solenoid valve and the second solenoid valve, and will not be described in detail herein.

In this way, the rotation direction of the winding drum of the winding mechanism 100 can be changed by controlling the electromagnetic valve, and further, the rope can be tightened and loosened to change the pulling force of the rope, so that the detection efficiency can be improved.

In some embodiments, the first set of solenoid valves is further configured to control a magnitude of a flow of hydraulic oil flowing from the first flow valve to the first hoist mechanism to vary a hoist speed of the first hoist mechanism; the second set of solenoid valves is also configured to control the magnitude of the flow of hydraulic oil from the second flow valve to the second hoist mechanism to vary the hoist speed of the second hoist mechanism.

As some embodiments, the flow rate of the hydraulic oil flowing from the first flow valve to the first hoisting mechanism may be controlled by controlling the current levels of the first solenoid valve and the second solenoid valve.

For example, when the first solenoid valve is not energized, the first hydraulic fluid port corresponding to the first solenoid valve may deliver hydraulic fluid to the first hoisting mechanism, and as the current applied to the first solenoid valve gradually increases, the flow rate at which the first hydraulic fluid port corresponding to the first solenoid valve delivers hydraulic fluid to the first hoisting mechanism gradually decreases; when the current loaded on the first electromagnetic valve reaches the maximum value, the first working oil port corresponding to the first electromagnetic valve cannot convey hydraulic oil to the first hoisting mechanism. For example, when the second solenoid valve is not energized, the first hydraulic fluid port corresponding to the second solenoid valve may supply hydraulic fluid to the second hoisting mechanism, and as the current applied to the second solenoid valve increases gradually, the flow rate of the hydraulic fluid supplied from the first hydraulic fluid port corresponding to the second solenoid valve to the second hoisting mechanism decreases gradually; when the current loaded on the second electromagnetic valve reaches the maximum value, the first working oil port corresponding to the second electromagnetic valve cannot convey hydraulic oil to the second hoisting mechanism.

It should be appreciated that the second set of solenoid valves operates in a similar manner to the first set of solenoid valves and will not be described in detail herein.

Thus, the hoisting speed of the hoisting mechanism 100 can be changed by controlling the electromagnetic valve, so that the rope can be quickly or slowly tightened and loosened to simulate various working scenes of the arm support, and the safety of the operation vehicle can be accurately detected.

Next, a hoist mechanism 100 and a hydraulic power system 110 according to some embodiments of the present disclosure are described in connection with fig. 10.

Fig. 10 is a schematic structural view of a hoist mechanism 100 and a hydraulic power system 110 according to some embodiments of the present disclosure.

As shown in fig. 10, the motor DD1 drives the hydraulic pump YB1 to draw the hydraulic pump from the tank YY1 to the P port. As some embodiments, an oil filter LY1 may be provided on an oil path from the oil tank YY1 to the hydraulic pump YB1 to filter impurities in the hydraulic oil. Here, BJ1 represents a pump inlet.

As some embodiments, a check valve DX1 may be provided on the oil path from the hydraulic pump YB1 to the P port to allow hydraulic oil to flow only toward the P port.

After the hydraulic oil flows into the P port, the hydraulic oil directly flows to the T port with the three-way flow valve ST1 connected to the P port in an on state. As some embodiments, a radiator SR1 may be provided on the oil path from the T port to the oil tank YY1 to reduce the temperature of the returned hydraulic oil.

With the three-way flow valve ST1 connected to the P port in the off state, hydraulic oil will flow to the first flow valve LL1 and/or the second flow valve LL2. As some embodiments, the on and off of the three-way flow valve ST1 is related to the operation states of the first flow valve LL1 and the second flow valve LL2. For example, in the case where the first flow valve LL1 and/or the second flow valve LL2 need to deliver hydraulic oil to the hoisting mechanism 100, the three-way flow valve ST1 is shut off; for another example, when the first flow valve LL1 and the second flow valve LL2 do not need to convey hydraulic oil to the hoisting mechanism 100, the three-way flow valve ST1 is turned on. Whether the first flow valve LL1 and the second flow valve LL2 need to convey hydraulic oil to the hoisting mechanism 100 may be controlled by the aforementioned cooperative operation of the first set of solenoid valves and the second set of solenoid valves, which are not described herein.

In some embodiments, first flow valve LL1 and/or second flow valve LL2 are three-position seven-way flow valves. Next, how the first hoisting mechanism operates will be described in the case where hydraulic oil flows to the first flow valve LL 1.

After the hydraulic oil flows to the first flow valve LL1, it is determined whether the hydraulic oil flows from the A2 working oil port to the first hoisting mechanism or from the B2 working oil port to the first hoisting mechanism according to the operating state of the first group of solenoid valves. For example, in the case where the first solenoid valve DC1 connected to the first flow valve is not energized or the solenoid valve is not loaded to the maximum current, and the second solenoid valve DC2 connected to the first flow valve is loaded to the maximum current, hydraulic oil flows from the A2 working port to the first hoisting mechanism, and the B2 working port receives the hydraulic oil that flows back from the first hoisting mechanism; for another example, when the second solenoid valve DC2 connected to the first flow valve is not energized or the solenoid valve is not loaded to the maximum current, and the first solenoid valve DC1 connected to the first flow valve is loaded to the maximum current, hydraulic oil flows from the B2 hydraulic fluid port to the first hoisting mechanism, and the A2 hydraulic fluid port receives hydraulic oil that flows back from the first hoisting mechanism.

As some embodiments, in the case where the oil pressure of the hydraulic oil delivered from the A2 hydraulic oil port to the first hoisting mechanism exceeds the first preset threshold, the corresponding first relief valve YL1 may divert a portion of the hydraulic oil so that the oil pressure is less than or equal to the first preset threshold; as other embodiments, in the case where the oil pressure of the hydraulic oil supplied from the B2 hydraulic oil port to the first hoisting mechanism exceeds the first preset threshold, the corresponding second relief valve YL2 may divert a portion of the hydraulic oil so that the oil pressure is less than or equal to the first preset threshold.

As some embodiments, in the case where hydraulic oil flows from the A2 working oil port to the first hoisting mechanism, hydraulic oil flows to the V1 oil port of the first hoisting mechanism and flows to the C3 oil port of the first hoisting mechanism via the pressure selection switch YX1, and hydraulic oil flowing from the C3 oil port can release the brake restriction of the spool of the first hoisting mechanism (i.e., the spool enters a rotatable state); then, hydraulic oil flows from a V1 oil port of the first hoisting mechanism to a C1 oil port of the first hoisting mechanism to drive the winding drum to rotate; similarly, in the case where hydraulic oil flows from the B2 working oil port to the first hoisting mechanism, hydraulic oil flows to the V2 oil port of the first hoisting mechanism and flows to the C3 oil port of the first hoisting mechanism via the pressure selection switch YX1, and the hydraulic oil flowing out of the C3 oil port can release the brake restriction of the spool of the first hoisting mechanism; and then, hydraulic oil flows from the V2 oil port of the first hoisting mechanism to the C2 oil port of the first hoisting mechanism to drive the winding drum to rotate in the opposite direction.

In some embodiments, the hydraulic interlock device YS1 is provided on the oil path from the V1 oil port of the first hoisting mechanism to the C1 oil port of the first hoisting mechanism and on the oil path from the V2 oil port of the first hoisting mechanism to the C2 oil port of the first hoisting mechanism, and this device can realize that hydraulic oil cannot flow from the V1 oil port of the first hoisting mechanism to the C2 oil port of the first hoisting mechanism in the case where hydraulic oil flows from the V1 oil port of the first hoisting mechanism to the C1 oil port of the first hoisting mechanism, and hydraulic oil cannot flow from the V2 oil port of the first hoisting mechanism to the C1 oil port of the first hoisting mechanism in the case where hydraulic oil flows from the V2 oil port of the first hoisting mechanism to the C2 oil port of the first hoisting mechanism. Thus, the hydraulic oil can flow unidirectionally, and the safety of the working vehicle can be detected more accurately.

As some embodiments, an accumulator XN1 may be provided in the first hoisting mechanism to ensure stable oil pressure.

It should be understood that the second flow valve LL2 is similar to the first flow valve LL1 in structure and operation, the third solenoid valve DC3 and the fourth solenoid valve DC4 are similar to the first solenoid valve DC1 and the second solenoid valve DC2 in structure and operation, the third overflow valve YL3 and the fourth overflow valve YL4 are similar to the first overflow valve YL1 and the second overflow valve YL2 in structure and operation, the hydraulic interlock device YS2 is similar to the hydraulic interlock device YS1 in operation, and the second winding mechanism is similar to the first winding mechanism in structure and operation, and the description thereof is omitted.

In some embodiments, pressure sensors are respectively disposed at the M port (the oil port is a detection oil port, the oil pressure of the oil port is the oil pressure of the P port), the A2 working oil port, the B2 working oil port, the A3 working oil port and the B3 working oil port, and the values measured by the pressure sensors can be stored and displayed in the man-machine interaction system 130 for the staff to monitor the oil pressure in real time.

In some embodiments, a speed encoder is provided on the motor to measure the rotational speed of the motor, and the measured rotational speed data may be sent to the motor drive. The winding speed of the winding mechanism 100 and the rope winding and unwinding amounts of the winding mechanism 100 can be obtained according to the rotation speed of the motor, and the winding speed, the rope winding amount and the rope unwinding amount can be stored and displayed in the man-machine interaction system 130 for real-time monitoring of staff. As some embodiments, the first and second hoisting mechanisms may each have a speed encoder.

In some embodiments, the lifting of the hoisting mechanism 100 may be controlled by a handle. For example, in case the handle is pushed forward, the hoist unwinds the rope; and under the condition that the handle is pulled backwards, the winch receives the rope.

As some embodiments, the hoisting speed can be controlled by the force of pushing the handle; as other embodiments, a predetermined winding speed may be input on the man-machine interaction system 130 to cause the winding mechanism 100 to wind at the predetermined winding speed; as still other embodiments, the control system 140 may automatically match the hoisting speed according to the magnitude of the preset tension value. For example, hoisting is performed at a faster speed in the case that the preset tension value is greater than the preset tension threshold value; for another example, the winding is performed at a slower speed in the case where the preset tension value is less than the preset tension threshold value. Therefore, the hoisting speed can be flexibly controlled, and the detection efficiency is improved.

In some embodiments, the detection device further comprises a power supply system. In some embodiments, the power supply system may provide power to the hydraulic power system 110, the tension sensor 120, the human-machine interaction system 130, the control system 140, and the chassis mechanism.

As some embodiments, the power supply system may be provided on a frame of the chassis mechanism. For example, the power supply system may be powered by a battery, such as a lead acid battery, for charging. The power supply system is provided with a power switch for powering up and powering down the whole power supply system. For example, the power switch may be turned off without detecting that the device is not operating. The power supply of the power supply system is divided into three parts, the first part supplies power to the hydraulic power system 110, for example, 48V direct current is connected with a motor driver, and the motor driver controls the motor to work; the second portion provides power to the control system 140, such as a 48V lead acid battery, through a DC/DC converter, converting 48V direct current to 24V direct current to provide power to the control system 140; the third portion provides power to the human-machine interaction system 130, such as a 48V lead-acid battery, through a DC/DC converter, converting 48V DC power to 12V DC power to provide power to the human-machine interaction system 130.

Next, a power supply system according to some embodiments of the present disclosure is described in connection with fig. 11.

As shown in fig. 11, the motor driver is connected with the motor, the 48V dc power of the battery G1 is connected with the J1-1 interface, the J1-22 interface and the J1-33 interface of the motor driver, and the 48V dc power of the battery G1 is also connected with the "b+" interface of the motor driver to supply power to the motor.

As some embodiments, the programming module is coupled to the motor drive via the J1-25 interface, the J1-28 interface, and the J1-29 interface of the motor drive. Here, the programming module may be used to configure the functions of the motor driver.

As some embodiments, the temperature sensor is coupled to the motor and transmits temperature data to the motor drive via the J1-8 interface of the motor drive. In this way, in case the temperature of the motor is too high, the motor driver may stop driving the motor to protect the motor.

As some embodiments, the speed encoder is connected to the motor and transmits the rotational speed data to the motor drive via the J1-32 interface, J1-31 interface of the motor drive.

As some embodiments, the J1-13 interface of the motor drive is connected to the J1-6 interface via a relay coil XQ1 control loop. When the motor driver is powered on, the relay coil XQ1 closes the contact switch K1, thereby supplying power to the motor.

As some embodiments, the J1-23 interface and the J1-35 interface of the motor driver are connected with the CAN bus, so that the temperature data measured by the temperature sensor and the rotation speed data measured by the speed encoder CAN be transmitted to the man-machine interaction system 130 through the CAN bus.

As some embodiments, battery G1 may be charged by charger CD 1. As some embodiments, fuses may be provided on the circuitry of the power supply system to protect the circuitry.

As some embodiments, OP1 is an output that supplies power to control system 140; OP2 is an output terminal for supplying power to the human-computer interaction system 130.

Here, the first condition is that the tension of the first rope measured by the first tension sensor is equal to a first preset tension value, and the second condition is that the tension of the second rope measured by the second tension sensor is equal to a second preset tension value.

For example, in the case where the user inputs a first preset tension value, the hydraulic power system 110 is controlled to drive the hoisting mechanism 100 such that the first condition is satisfied; for another example, in case that the user inputs a second preset tension value, the hydraulic power system 110 is controlled to drive the hoisting mechanism 100 such that the second condition is satisfied; also for example, in the case where the user inputs the first preset tension value and the second preset tension value, the hydraulic power system 110 is controlled to drive the hoisting mechanism 100 such that the first condition and the second condition are satisfied.

Similarly, the second rope is connected with the second detection tool, and the second detection tool is connected with the arm support of the operation vehicle so as to realize the connection of the second rope and the arm support of the operation vehicle.

At step S4, at least one of a first preset tension value for the first rope and a second preset tension value for the second rope is input through the human-machine interaction system 130.

According to the working scene to be simulated, the user can input at least one of the first preset tension value and the second preset tension value. The detection apparatus automatically controls the hydraulic power system 110 to drive the hoisting mechanism 100 in the manner described above such that at least one of the first condition and the second condition is satisfied.
