Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0044] A diesel engine electric cranking device described in an embodiment of the present application includes a cranking assembly 1, an electronic control assembly 2 and a hand-held part 3. The electronic control assembly 2 is arranged on one side of the cranking assembly 1 along a direction perpendicular to the axial direction X of the cranking assembly 1 and is connected to the cranking assembly 1; the hand-held part 3 and the electronic control assembly 2 are arranged on the same side of the cranking assembly 1, and the hand-held part 3 is connected to the cranking assembly 1; the hand-held part 3 is arranged on a side of the electronic control assembly 2 away from the output end of the cranking assembly 1.

[0045] In the embodiment of the present application, the electronic control component 2 is arranged on one side of the turning gear assembly 1 along a side perpendicular to the axial direction X of the turning gear assembly 1, thereby effectively reducing the axial direction X size of the turning gear device, making it more suitable for electric turning gears in narrow spaces, effectively improving the turning efficiency in narrow spaces, and simplifying the operating steps; at the same time, a hand-held portion 3 is also provided on the side perpendicular to the axial direction X of the turning gear assembly 1, which can support the turning gear staff to hold the electric turning gear device for turning without increasing the axial direction X size of the electric turning gear device, or to connect the hand-held turning gear device with the diesel engine turning gear interface, thereby further improving the application flexibility of the electric turning gear device.

[0046] Specifically, in the embodiment of the present application, the crank assembly 1 is used to dock with the crank structure of the diesel engine and drive the crank structure to rotate the crank. The electric control assembly 2 is used to supply power to the crank assembly 1, drive the crank assembly 1 to rotate and control the direction of the crank assembly 1. The hand-held portion 3 is used to provide a hand-held portion 3 for the operator, so that the operator can directly hold the electric crank device to dock the crank assembly 1 with the diesel engine crank structure.

[0047] In some embodiments, the electronic control component 2 includes a controller 21 and an energy storage component 22. The controller 21 is conductively connected to the turning gear assembly 1. The energy storage component 22 is conductively connected to the controller 21 and the turning gear assembly 1. The energy storage component 22 is arranged on a side of the controller 21 away from the turning gear assembly 1.

[0048] In the embodiment of the present application, the controller 21 of the electronic control component 2 is mainly used to drive and control the forward and reverse rotation of the winch component 1. The energy storage component 22 can be a battery for storing electrical energy, so that the electric winch device can work in any operating environment, reducing the requirements for the surrounding circuit environment, thereby improving the application flexibility of the electric winch device.

[0049] In some embodiments, the electric turning device further includes a control switch 4 , which is disposed at one end of the handheld portion 3 close to the turning assembly 1 and connected to the handheld portion 3 , and the control switch 4 is conductively connected to the controller 21 .

[0050] In the embodiment of the present application, by setting the control switch 4 to be connected with the controller 21, the start and stop of the cranking assembly 1 can be manually controlled by turning off the control switch 4. In this way, the rotation angle of the cranking assembly 1 can be effectively controlled during cranking, and the diesel engine can be effectively controlled and stopped during cranking.

[0051] In some embodiments, the control switch 4 is a momentary switch.

[0052] In the embodiment of the present application, the control switch 4 can be a momentary switch. At this time, when the control switch 4 is pressed, the controller 21 receives a start cranking command, and the controller 21 starts to control the cranking assembly 1 to rotate to crank. When the control switch 4 is released, the corresponding controller 21 receives a stop cranking command. At this time, the controller 21 controls the cranking assembly 1 to stop cranking, thereby realizing the control and stop of the diesel engine cranking, making the control more precise.

[0053] In some embodiments, the electric winch device further includes a wireless receiver 5 and a remote controller 6 . The wireless receiver 5 is conductively connected to the controller 21 , and the remote controller 6 is communicatively connected to the wireless receiver 5 .

[0054] In the embodiment of the present application, the wireless receiver 5 is used to cooperate with the remote controller 6 to realize remote wireless control of the electric winch device. Therefore, when the operator is performing winch operation in a narrow space where it is difficult for the operator to enter and exit, the electric winch device can be docked with the diesel engine winch structure and relatively fixed, and then wireless control can be performed through the remote controller 6. At this time, the winch assembly 1 can be controlled at a certain distance from the electric winch device.

[0055] It should be noted that in the embodiment of the present application, when the electric turning gear device uses the wireless receiver 5 to control the turning gear, the button on the remote control 6 is pressed to send a control signal to the wireless receiver 5. After receiving the signal, the wireless receiver 5 transmits it to the controller 21, and the controller 21 controls the turning gear component 1 to perform the turning action; when the remote control 6 supplies the wireless receiver 5 with a signal to stop the turning gear, the wireless receiver 5 transmits the signal to the controller 21, and the controller 21 controls the turning gear component 1 to stop the turning action, thereby realizing the wireless control of the electric turning gear.

[0056] It should also be noted that the remote controller 6 has a wireless transmitter that cooperates with the wireless receiver 5 and is used to transmit signals with the wireless receiver 5. At the same time, the remote controller 6 also includes a wireless switch, which can be a momentary switch, and the wireless switch is connected to the wireless transmitter. When the wireless switch is pressed, the wireless control signal is sent to the wireless receiver 5 by means of the wireless transmitter, and the wireless receiver 5 transmits the signal to the controller 21, so that the controller 21 drives the control of the turning gear assembly 1 to perform the turning operation; when the wireless switch is released, the wireless control signal stops being sent, and the corresponding wireless receiver 5 cannot receive the control signal, and then the controller 21 stops driving the turning gear assembly 1 to turn the gear, so that the turning gear operation can be stopped at any time, thereby achieving more precise control of the turning gear rotation angle.

[0057] In some embodiments, the electric winch device also includes a control mode adjustment member 7, which is disposed on a side of the handheld portion 3 away from the electric control component 2 and is conductively connected to the electric control component 2; the control mode adjustment member 7 includes a wireless control gear and a wired control gear.

[0058] In the embodiment of the present application, a control mode adjustment member 7 is provided to realize switching between wired control and wireless control of the electric turning device.

[0059] Specifically, the control mode adjustment member 7 may be a toggle switch with two adjustment functions, namely, the wireless control position and the wired control position. When the control mode adjustment member 7 is in the wireless control position, the wired control switch 4 fails. At this time, the electric cranking device can only be controlled by controlling the remote controller 6 and the wireless receiver 5; when the control mode adjustment member 7 is in the wired control position, the wireless receiver 5 and the remote controller 6 fail. At this time, the electric cranking device can only be controlled by the control switch 4 to perform cranking.

[0060] It should be noted that the present application can be applied to more usage environments through the combination of wireless control and wired control, so that different control methods can be selected according to different turning environments, thereby improving the flexibility of the use of the electric turning device.

[0061] In some embodiments, the electric turning device further includes a steering adjustment member 8 , which is disposed on a side of the turning assembly 1 close to the handheld portion 3 , and the steering adjustment member 8 is conductively connected to the controller 21 .

[0062] In the embodiment of the present application, the steering adjustment member 8 is used to control the rotation direction of the output end of the barring gear assembly 1, so as to realize the barring gear structure rotating in different directions, thereby realizing effective barring.

[0063] In some embodiments, the steering adjustment member 8 includes a forward gear, a reverse gear, and a stop gear. When the steering adjustment member 8 is in the forward gear, the control switch 4 is closed or the wireless switch of the remote controller 6 is closed, and the controller 21 can only control the turning assembly 1 to turn the gear forward; when the steering adjustment member 8 is in the reverse gear, the control switch 4 is closed or the wireless switch of the remote controller 6 is closed, and the controller 21 can only control the turning assembly 1 to turn the gear reversely; when the steering adjustment member 8 is in the stop gear, no matter whether the control switch 4 is closed or the wireless switch of the remote controller 6 is closed, the turning assembly 1 cannot turn the gear, which effectively avoids misoperation and ensures operational safety.

[0064] In some embodiments, the turning gear assembly 1 includes a driving component 11, a deceleration component 12 and an adapter, the driving component 11 is conductively connected to the controller 21; the deceleration component 12 is arranged on one side of the driving component 11 along the axial direction X of the turning gear assembly 1, and the input end of the deceleration component 12 is connected to the output end of the driving component 11; the adapter is arranged on the side of the deceleration component 12 away from the driving component 11 along the axial direction X of the turning gear assembly 1, the adapter is connected to the output end of the deceleration component 12, the adapter forms the output end of the turning gear assembly 1, and the hand-held part 3 is arranged on the side of the electronic control component 2 away from the adapter.

[0065] In the embodiment of the present application, the driving component 11 is used to receive the signal of the controller 21 to rotate, and the deceleration component 12 is connected to the output end of the driving component 11, and is used to increase the torque output by the driving component 11, so that the smaller volume of the cranking assembly 1 can output a larger torque, so that the larger volume of the diesel engine cranking structure can be driven to rotate. Among them, the adapter is used to connect to the output end of the deceleration component 12 to achieve the docking of the cranking assembly 1 and the diesel engine cranking structure, thereby driving the diesel engine cranking structure to rotate, so as to achieve diesel engine cranking.

[0066] It should be noted that the diesel engine cranking structure may be a flywheel, and the rotation of the flywheel drives the crankshaft of the diesel engine to rotate, thereby achieving the diesel engine cranking.

[0067] In some embodiments, the driving component 11 is a motor, and the speed reduction component 12 is a planetary gear set.

[0068] In the embodiment of the present application, the driving component 11 can be a motor, and the controller 21 can control the motor to rotate to output the corresponding torque, wherein the motor can be selected from different models according to the needs. The planetary gear set is used to transmit the power of the motor output end to the output end of the planetary gear set, that is, to the adapter, and at the same time change the torque output by the motor. The planetary gear set used in the present application can effectively ensure that the deceleration component 12 has a high transmission efficiency and a relatively small size, which can meet the needs of diesel engine cranking in a small space.

[0069] In some embodiments, along a direction perpendicular to the axial direction X of the barring gear assembly 1 , the cross section of the adapter is a polygon.

[0070] In the embodiment of the present application, by circumferentially arranging the adapter into a polygonal structure, the adapter can be matched with the corresponding cranking interface of the diesel engine and can be limited to each other, thereby achieving effective power transmission and facilitating the smooth rotation of the diesel engine cranking structure.

[0071] In some embodiments of the present application, the adapter can be a standard output square head, and the corresponding cranking interface on the diesel engine can also be a square hole that matches the output square head, so that the square head can be directly inserted into the cranking interface, and the cranking structure can be smoothly turned with the cranking car. At the same time, the use of a standard output square head facilitates the subsequent direct installation of an adapter that matches the output square head, so that the electric cranking device of the present application is adapted to the cranking structure of more models of diesel engines, thereby improving the applicability of the electric cranking device.

[0072] In some embodiments, the electric turning device further includes a reaction arm 9 , which is connected to the deceleration component 12 ; the reaction arm 9 can rotate along the circumferential direction of the deceleration component 12 .

[0073] In the embodiment of the present application, by providing a reaction arm 9 and utilizing the cooperation between the reaction arm 9 and the partial structure on the diesel engine, it is possible to achieve fixed positioning of the portion of the electric turning device other than the adapter, effectively preventing the components of the electric turning device other than the adapter from rotating during the turning process, thereby achieving the amplification of the torque of the driving component 11 through the deceleration component 12 and conversion with the turning joint, and transmitting it to the flywheel of the diesel engine, so as to achieve the purpose of turning.

[0074] It should be noted that the electric winch device is connected to the winch interface of the winch structure through an adapter to achieve mutual limitation. The electric winch device is rotated to a certain angle through the reaction arm 9 until it abuts against the bolts and other body structures around the winch structure. In this way, the overall fixation of the electric winch device is further achieved, thereby meeting the requirement that the electric winch device can draw the rope to rotate and fix itself during the winch operation.

[0075] In some embodiments, the reaction arm 9 includes a first section 91 and a second section 92 . The first section 91 is connected to the deceleration component 12 , and the second section 92 is connected to an end of the first section 91 away from the deceleration component 12 . The second section 92 is bent relative to the first section 91 .

[0076] In the embodiment of the present application, the reaction arm 9 is set to a structure in which the first section 91 and the second section 92 are relatively bent. At this time, the second section 92 can be used to abut against some bolts or other structures on the diesel engine, thereby limiting the overall movement of the electric winch device. At the same time, since the reaction arm 9 only abuts against part of the structure of the diesel engine body, rather than being locked on the diesel engine body with bolts, the reaction arm 9 is more flexible in fixing and can adapt to a variety of models. The reaction arm 9 is designed according to the diesel engine structure, and at the same time, the adapter and the winch interface of the winch structure are mutually limited, so that the electric winch device can be easily mounted on the diesel engine, thereby facilitating wireless remote control operation.

[0077] In some embodiments, the electric turning device includes a shell 10, the shell 10 has a accommodating cavity 101, the turning assembly 1 and the electronic control assembly 2 are arranged in the accommodating cavity 101, the output end of the turning assembly 1 is arranged outside the shell 10, the hand-held part 3 is connected to the shell 10, and the hand-held part 3 is arranged along the axial direction X of the turning assembly 1 and is partially spaced from the shell 10.

[0078] In the embodiment of the present application, the housing 10 accommodates components such as the electronic control component 2 and the winch component 1, so that the electric winch device of the present application forms an integrated setting, which makes it easier to move, assemble and mount the entire electric winch device, and makes it easier to operate the winch.

[0079] Correspondingly, a diesel engine electric cranking method according to an embodiment of the present application uses an electric cranking device as in any one of the aforementioned embodiments, and the method comprises the following steps: holding a handhold to connect the output end of the cranking assembly to the diesel engine cranking structure; determining the rotation direction of the output end of the cranking assembly; determining the control mode of the electric cranking device; and starting the electronic control assembly to control the rotation of the output end of the cranking assembly.

[0080] It can be understood that the electric turning method of the present application, with the help of the electric turning device, can achieve effective electric turning in a small space, improve the turning efficiency, and simplify the operating steps; at the same time, it can select the appropriate control method according to the application scenario to improve the applicability of the electric device.

[0081] The specific steps are as follows:

[0082] S100: Holding the handgrip, connect the output end of the cranking assembly to the cranking structure of the diesel engine.

[0083] Specifically, the electric turning device is assembled through the housing 10 to form an integrated structure. At this time, the electric turning device can be picked up and moved as a whole by using the hand-held portion 3. At the same time, the electric turning device of the embodiment of the present application is suitable for a small space. Therefore, the overall body is small and can be held and moved at will. Move the electric turning device into a small space and close to the diesel engine turning structure, which is conducive to the next step of operation.

[0084] The output end of the winch assembly 1 is connected to the winch structure of the diesel engine. Specifically, the adapter of the winch assembly 1 can be connected to the winch interface of the diesel engine winch structure to achieve the installation connection of the electric winch device. At the same time, the adapter and the winch interface are connected to limit the position to achieve the mounting of the electric winch device. Furthermore, the electric winch device can also be provided with a reaction arm 9, which is rotated to a suitable position and abutted against the bolts or other body structures near the diesel engine winch structure to achieve the fixation of the electric winch device, thereby further stabilizing the stability of the electric winch device mounted on the diesel engine, so that it is convenient for the operator to stay away from the electric winch device and move to the inspection point for winch control.

[0085] S200: Determine the rotation direction of the output end of the turning gear assembly.

[0086] Specifically, by rotating and adjusting the steering adjustment member 8, the forward gear position or the reverse gear position can be switched accordingly, and the turning gear assembly can be controlled to rotate forward or reverse accordingly, so that forward turning or reverse turning can be achieved when the turning gear assembly rotates.

[0087] S300: Determine the control method of the electric turning device.

[0088] Specifically, the control mode adjusting member 7 may be rotated to switch to a wired control position or a wireless control position, thereby realizing wired control or wireless control.

[0089] S400: Start the electronic control component to control the output end of the turning gear component to rotate.

[0090] When the gear is switched to the wired control position, the handheld part 3 is held, and then the control switch 4 is turned on, and the corresponding turning operation can be started. When the gear is switched to the wireless control position, the remote controller 6 is held and moved to the checkpoint position, and the wireless switch on the remote controller 6 is pressed to send the wireless control signal to the wireless receiver 5, and the wireless receiver 5 transmits the signal to the controller 21, and the corresponding controller 21 controls the driving component to rotate forward or reverse to perform turning.

[0091] Among them, both the control switch 4 and the wireless switch can be momentary switches. At this time, it can be realized that the cranking starts when the switch is pressed, and the cranking stops when the switch is released. In this way, the control and stop can be realized, and the cranking accuracy is improved.

[0092] When the turning operation is completed, rotate the steering adjustment member 8 to the stop position and take out the electric turning device.

[0093] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
