The implementation, functional features and advantages of the objectives of the present application will be further explained with reference to the accompanying drawings.
Detailed Description
First, the relevant working principle of the truck-mounted crane will be explained.
The vehicle-mounted power take-off can be divided into single-switch power take-off and double-switch power take-off according to the structural difference of a vehicle gearbox. The single-switch power take-off means that power take-off control can be realized only through one power take-off switch no matter in a driving condition or a parking condition. The double-switch power take-off refers to the condition that the power take-off function is controlled to be started through different power take-off switches under the driving working condition and the parking working condition respectively, the control switch under the driving working condition is called as a driving power take-off switch, and the control switch under the parking working condition is called as a parking power take-off switch.
Referring to fig. 1, fig. 1 is a schematic diagram of a parking power take-off control circuit, a DPF regeneration prohibition control circuit, and an engine forced start control circuit.
As shown in fig. 1, a truck mounted crane of a truck mounted special vehicle generally takes power from a transmission case with the vehicle stopped in place, thereby operating the crane. The double-switch power take-off truck-mounted crane mainly comprises a driving power take-off electromagnetic valve and a parking power take-off electromagnetic valve which are connected in parallel, wherein the driving power take-off electromagnetic valve and the parking power take-off electromagnetic valve are respectively connected with a power supply, a driving power take-off switch is arranged between the driving power take-off electromagnetic valve and the power supply, and a parking power take-off electromagnetic valve is arranged between the parking power take-off electromagnetic valve and the power supply.
For the double-switch power take-off truck-mounted crane, the related power take-off control method is that firstly, a control lever of a gearbox is placed in a neutral position, and then a vehicle is started, because the existing vehicles in the market are designed with neutral starting logic due to safety consideration; secondly, closing a parking power take-off switch to enable a parking power take-off electromagnetic valve to be attracted, connecting high-pressure air from an air storage cylinder to a neutral position air path of an auxiliary box of the gearbox by the parking power take-off electromagnetic valve, and enabling an auxiliary box synchronizer to be in a neutral position by utilizing air pressure difference so as to enable the vehicle to be incapable of running; then closing the traveling power take-off switch to enable the traveling power take-off electromagnetic valve to be closed, and enabling the traveling power take-off electromagnetic valve to connect high-pressure air from the air storage cylinder to a power take-off working air path on the gearbox to enable the power take-off to work in a gear shifting mode; finally, according to the actual working condition requirement, the transmission is engaged into the required low gear region, at the moment, the power takeoff still works in gear, and the vehicle can keep still in place due to the fact that the auxiliary box of the gearbox is located in the neutral position, and therefore the fact that an operator can sit on the crane to operate the crane arm to work is achieved.
However, this method is not perfect in terms of safety and convenience.
In the aspect of safety, with the implementation of a new national six (national sixth-stage motor vehicle pollutant emission standard) emission regulation, the vehicle emission level in the current market is gradually upgraded to the national six, and the national six vehicle models have a DPF (Diesel Particulate Filter) passive regeneration function which is usually automatically started according to a sensor signal of an emission post-processing system in the running process of an engine, and the rotating speed of the engine is automatically increased to increase the exhaust temperature and the exhaust volume, so that the aim of reducing carbon deposition in an emission post-processor is fulfilled. Once the DPF passive regeneration function happens when the vehicle-mounted crane is in the in-process of work, engine speed promotes by a wide margin in the short time this moment, directly influences the operating power of crane arm, and because engine speed promotes automatically this moment, does not receive manual operation control, probably causes goods swing or tumble etc. has great risk to personal, property safety.
In some special use environments, in order to close the DPF passive regeneration function for a short time, the six domestic vehicles are generally provided with a control circuit for the DPF regeneration prohibition function, and the DPF regeneration function is closed by manually and actively closing a DPF regeneration prohibition switch. Therefore, the situation that a truck-mounted crane operator forgets to close the DPF regeneration prohibition switch before operation can occur, so that the possibility that the DPF is passively regenerated and opened exists in the working process of the vehicle-mounted crane, and the rotating speed of the engine is automatically increased in a short time without being artificially controlled, so that safety risks such as cargo swinging or tipping can be caused.
In terms of convenience, when a crane operator wishes to remotely start the vehicle again at the crane station after completing a round of crane operation and remotely turning off the vehicle, the vehicle cannot be started because the transmission operating lever is not in neutral at this time, and the operator must leave the crane to return to the vehicle cab to re-engage neutral in order to start the vehicle, then start power take-off according to the related power take-off control method, and finally return to the crane station. On the basis of a related power takeoff control method, an operator cannot remotely start a vehicle on a crane station, and great inconvenience is brought to the work of the operator.
The existing engine generally has a forced start function, namely, the engine can be forced to start only by screwing an ignition lock in a starting gear for a long time (the time can be calibrated) under the condition of no neutral gear or not. After a crane operator completes one round of crane operation and remotely extinguishes the vehicle, the crane operator can select to remotely start the vehicle through a forced start function at a crane station, but when a parking power take-off switch is not closed or is disconnected by misoperation of other people, the auxiliary gearbox is in a neutral position state, in the case that once the operator remotely and forcibly starts the vehicle, the vehicle can drive with a gear under the condition that a cab is unmanned due to the fact that the operator is located on the crane, and great safety threats are caused to the operator located at the crane station and people around the vehicle.
According to the situation, the vehicle can be started only when the gearbox is in a neutral position, the power take-off can be realized only when the gearbox is in a gear shift state, and the logics of the power take-off and the power take-off are mutually contradictory, so that an operator cannot realize the remote vehicle starting function under the existing power take-off control method. When the operation is stopped and the vehicle is flamed out, the operator needs to return to the cab of the vehicle from the crane station, restart the parking power take-off according to the existing power take-off control method, and then return to the crane station from the cab for operation, so that great inconvenience is brought to the vehicle-mounted crane operation process. When a worker attempts to use the engine kick-start function, it is necessary to ensure that the park power take-off switch is closed to ensure that the transmission sub-tank is in neutral. However, in the existing power take-off control method, because the power take-off control circuit and the engine forced starting circuit are mutually independent circuits, the parking power take-off switch cannot be ensured to be in a closed state when the vehicle is started remotely, once a crane operator starts the vehicle remotely and forcibly when the parking power take-off switch is not closed or is disconnected by misoperation of other people, the vehicle can drive with a gear under the condition that a cab is unmanned, and great safety threats are caused to the operator at a crane station and the personnel around the vehicle.
Based on the above reasons, the related power take-off control method has potential safety hazards in terms of safety and has an optimization space in terms of convenience, so the embodiment of the application provides a power take-off control system and method for an automobile truck-mounted crane and an automobile to solve the problems.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The flowcharts shown in the figures are illustrative only and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution order may be changed according to the actual situation.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 2, fig. 2 is a schematic view of a power take-off control system of an automobile truck-mounted crane provided in the present application, the system including:
the first switch is arranged between a power supply and the power taking solenoid valve and is configured to control the power supply and the power taking solenoid valve to be conducted when the first switch is closed so as to enable the crane to start power taking; when the power supply is disconnected, the power supply is controlled to be disconnected with the power take-off electromagnetic valve, so that the crane stops taking power;
a second switch in parallel with the DPF regeneration inhibit switch configured to close and open in synchronization with the first switch to control the DPF to inhibit regeneration when closed.
It should be noted that the second switch is connected in parallel to the DPF regeneration prohibition switch, and the second switch can perform the same function as the DPF regeneration prohibition switch, that is, controls the DPF to prohibit regeneration when closed. Meanwhile, the first switch and the second switch for controlling the power take-off of the crane are synchronously closed and opened, namely when the first switch is closed to enable the crane to start power take-off work, the second switch is synchronously closed to control the DPF to prohibit regeneration, and when the first switch is opened to enable the crane to stop power take-off, the second switch is synchronously opened to cancel the prohibition of the DPF regeneration. Therefore, DPF regeneration of the crane of the truck crane is forbidden in the whole process of the parking power takeoff operation process, the situation that the rotating speed of an engine is increased to cause the fast regeneration and the starting of the DPF when the crane works in the power takeoff process, so that the crane arm is not controlled is avoided, the stability and the safety in the working process of the crane are improved, and the personal safety and the property safety of related personnel in the working process of the crane are guaranteed.
It is worth mentioning that the second switch is connected in parallel with the DPF regeneration prohibiting switch through a wire. According to the embodiment of the application, the first end of the second switch is connected with the first end of the DPF regeneration forbidding switch through a conducting wire, the second end of the second switch is connected with the second end of the DPF regeneration forbidding switch through a conducting wire, and the second switch is connected with the DPF regeneration forbidding switch in parallel. After parallel connection, the second switch and the regeneration prohibiting switch have the same functions, namely, when the second switch is closed, the PDF is controlled to prohibit regeneration, and when the second switch is opened, the DPF normally runs. And the second switch is independent from the DPF regeneration forbidding switch, and the DPF regeneration forbidding switch can still forbid DPF regeneration when closed without influencing the second switch.
In some embodiments, the solenoid valves in the power take-off control system of the truck-mounted crane include a driving power take-off solenoid valve and a parking power take-off solenoid valve, the first switch is disposed between the power supply and the parking power take-off solenoid valve, and the first switch is configured to control the power supply and the parking power take-off solenoid valve to be switched on and off.
In some embodiments, the first switch comprises a park power take off switch. The parking power take-off switch is arranged between the power supply and the parking power take-off electromagnetic valve and is used for controlling the power supply and the parking power take-off electromagnetic valve to be switched on and off, so that the first switch can be the parking power take-off switch.
In a preferred embodiment, the first switch and the second switch form a dual-contact switch.
Specifically, the original parking power take-off switch is a single-contact switch, the original single-contact switch can be replaced by a double-contact switch, the parking power take-off switch is connected with one pair of contacts and keeps unchanged, and the other pair of contacts are respectively connected with two ends of the contacts of the DPF regeneration-forbidding switch to serve as a second switch. Under the connection mode, when the power take-off function is started by the truck-mounted crane, the power take-off switch is in a closed state, the second switch is also closed, the DPF regeneration forbidding circuit is simultaneously connected with the second switch, the purpose that the DPF regeneration is forbidden in the whole process of the truck-mounted crane in the power take-off operation process is realized, the automatic increase of the rotating speed of an engine in the process of hoisting objects by the crane is avoided, the potential personal and property safety hazards caused by goods swinging or rollover and the like are avoided, the stability and the safety in the working process of the crane are improved, and the personal safety and the property safety of related personnel in the working process of the crane are ensured.
In some embodiments, the dual-contact switch comprises a dual-contact relay.

As a preferred embodiment, the third switch is an automatic reset remote control switch configured to be automatically turned off when the first switch is turned off to turn off the engine forced start signal transmission port.
It is worth to be noted that, in the embodiment of the present application, the automatic reset remote control switch is disposed at the engine forced start signal transmission port, and the parking power take-off switch is associated with the engine forced start signal transmission port through the automatic reset remote control switch, so as to form a control loop of the parking power take-off switch → the automatic reset remote control switch → the engine forced start signal transmission port. Only under the premise that the parking power take-off switch is closed, the automatic reset remote control switch receives the remote control signal and is closed, a closed loop is formed, and the forced starting signal transmission port of the engine can be conducted, so that the forced starting signal of the engine is transmitted to the engine controller, and the engine is forcibly started. If the parking power take-off switch is in an off state, the automatic reset remote control switch cannot form a closed loop after receiving the remote control signal and being closed, so that the transmission port of the motor forced start signal cannot be conducted, and the motor cannot be forced to start. The remote starting of the vehicle can be realized only when the parking power take-off switch is in a closed state, the potential safety risk of the vehicle running under the condition that a cab is unmanned due to human errors before a crane operator remotely forcibly starts the vehicle is eliminated, and the remote starting of the vehicle under the condition of safety guarantee is realized.
