[0024] like Figure 1 As shown, a preferred embodiment of the utility model provides a hybrid pump truck, including a power distribution device 1, a power battery 9, a range extender assembly 7, a drive motor 2, a clutch assembly 12, a traveling part and an upper part. The power battery 9 and the range extender assembly 7 are electrically connected to the power distribution device 1, and the power distribution device 1 is electrically connected to the drive motor 2, and is used for the power battery 9 and the range extender assembly 7 to provide electrical energy to the drive motor 2. The clutch assembly 12 is transmission-connected between the drive motor 2 and the traveling part and between the drive motor 2 and the upper part, and is used for selectively transmitting the power provided by the drive motor 2 to the traveling part and / or the upper part, thereby realizing the integration of driving, pumping, and material distribution functions, and providing energy through power battery 9 or range extender assembly 7 to generate electricity, etc., while saving energy, it also takes into account the characteristics of power and pumpable sustainability.

[0025] In a preferred embodiment of this embodiment, the active part of the clutch assembly 12 can be connected to the output end shaft of the drive motor 2. The connection methods usually include flange connection, key connection, etc. to ensure the reliability and concentricity of the connection. The clutch is engaged and disengaged by controlling the current on and off of the drive motor 2, so that the drive motor 2 and the clutch assembly 12 are integrated to save space.

[0026] In this embodiment, the walking part includes a gearbox 3 and a transmission shaft 4. The power distribution device 1, the drive motor 2, the gearbox 3, and the transmission shaft 4 are connected in sequence. The power distribution device 1 provides electrical energy to the drive motor 2, and the drive motor 2 drives the gearbox 3 and the transmission shaft 4 to drive the pump truck to move.

[0027] In this embodiment, the upper mounting part includes a pumping mechanism 5 and a stirring mechanism 6. The power distribution device 1, the drive motor 2, and the pumping mechanism 5 are connected in sequence. The power distribution device 1 supplies electrical energy to the drive motor 2, and the pumping mechanism 5 performs construction operations to achieve the functions of pumping and boom and outrigger. The stirring mechanism 6 includes a gear pump motor 62 and a gear pump 61. The gear pump motor 62 is electrically connected to the power distribution device 1, and the power distribution device 1 directly supplies power to the stirring mechanism 6, causing the gear pump motor 62 inside the stirring motor to start running and driving the gear pump 61 to work. The advantage of directly connecting to the power distribution device 1 is that when the pump truck is not pumping, moving the boom, or moving the outriggers, the drive motor 2 can be stopped. In this way, during the cleaning and stirring processes, other pump groups do not need to rotate, and only the gear pump 61 works, greatly reducing the energy consumption during separate stirring or cleaning.

[0028] Specifically, the drive motor 2 in this embodiment is a double-output shaft motor with a clutch assembly. Both ends of the motor can be connected to pump groups or transmission components, and the power transmission can be disconnected through the clutch assembly 12. It can select to use one end or both ends to output power according to different working requirements, enabling the equipment to operate efficiently under various working conditions. Therefore, when the pump truck is traveling, the clutch assembly 12 disconnects the drive motor 2 from the pumping mechanism 5, causing the drive motor 2 to drive the gearbox 3 and the drive shaft 4 to drive the pump truck to move; when the pump truck is under construction, the connection between the drive motor 2 and the drive shaft 4 is disconnected, causing the drive motor 2 to drive the pumping mechanism 5 to perform pumping. According to the actual load situation, the power can be flexibly distributed to different pump groups or drive parts, improving the energy utilization efficiency and reducing energy consumption.

[0029] In this embodiment, the hybrid pump truck further includes a control unit. The drive motor electronic control 21 electrically connected to the drive motor 2 and the power distribution device 1 and the gear pump motor electronic control 63 electrically connected to the gear pump motor 62 and the power distribution device 1 are both communicatively connected to the control unit. The control unit controls the operation of the drive motor 2 and the gear pump motor 62. When the pump truck needs the gear pump 61 to work to achieve the cleaning and stirring functions and the pump truck is not pumping, the control unit cuts off the connection between the power distribution device 1 and the drive motor 2 through the drive motor electronic control 21, and connects the power distribution device 1 to the gear pump motor 62 through the gear pump motor electronic control 63. The power distribution device 1 directly transmits power to the gear pump 61, causing the gear pump 61 to start running.

[0030] Specifically, when the vehicle is running or pumping and the gear pump 61 is not used, the control unit controls the gear pump motor electronic control 63 to disconnect the gear pump motor 62 from the power distribution device 1, improving the energy utilization efficiency and reducing energy consumption.

[0031] Specifically, the hybrid pump truck further includes an air conditioner 11 electrically connected to the power distribution device 1 and communicatively connected to the control unit, which provides a comfortable working environment for the operator. Moreover, an appropriate temperature can extend the service life of in-vehicle electronic devices and ensure their stable operation.

[0032] Specifically, the hybrid pump truck further includes a voltage converter 10 electrically connected between the power distribution device 1 and the in-vehicle electronic devices of the hybrid pump truck. In this embodiment, it is a DC-DC converter, which converts direct current of a certain voltage level in the pump truck power supply system into direct current of another voltage level to meet the power supply requirements of different devices and systems.

[0033] In this embodiment, the hybrid pump truck further includes an external power supply interface 8. The power distribution device 1 has three different energy sources. The power battery 9 is installed inside the pump truck to provide power for the power distribution device 1; the external power supply interface is used to provide power for the power distribution device 1 by using an external power supply when connecting to the external power supply; power can also be generated through the range extender assembly 7 to charge the power distribution device 1.

[0034] Specifically, the power battery 9 is used to provide power for the power distribution device 1 when the external power supply interface 8 is not connected to an external power supply and the power of the power battery 9 is not lower than a preset power threshold. The range extender assembly 7 is used to provide power for the power distribution device 1 when the external power supply interface 8 is not connected to an external power supply and the power of the power battery 9 is lower than the power threshold.

[0035] Specifically, the power battery 9 further includes a fast charging socket 91, which is used to connect to an external power supply to charge the power battery 9. When the pump truck is in a non-operating state, the power battery 9 is charged through the fast charging socket 91 to prevent the situation of insufficient power when the pump truck is running.

[0036] In this embodiment, the hybrid pump truck further includes a fuel tank. The range extender assembly 7 consists of an engine and a generator. The engine is connected to the fuel tank, and the engine is drivingly connected to the generator. The range extender assembly 7 is used to obtain fuel from the fuel tank when the external power supply interface 8 is not connected to an external power supply and the power of the power battery 9 is lower than the power threshold, and burn the fuel to generate power to drive the generator to generate electricity and provide power for the power distribution device 1.

[0037] Specifically, the range extender assembly 7 includes a range extender electronic control 71, and the range extender electronic control 71 is signal-connected to the control unit and is used to control whether the range extender assembly 7 starts generating electricity.

[0038] Specifically, compared with a traditional pump truck during operation or driving, in the range-extended hybrid architecture, the engine is not mechanically connected to the pumping mechanism 5 or the transmission shaft 4; in the traditional pump truck, the operation of the engine is affected by the load, while in the range-extended pump truck during operation or driving, the engine can generate electricity at a fixed point and the working area is stable.

[0039] Compared with traditional fuel pump trucks, the hybrid pump truck provided by the embodiments of the present application can save energy and reduce emissions and pumping costs because when driving and pumping, the double-output-shaft clutch motor can be used to select one end or use both ends to output power according to different working requirements. In addition, compared with pure electric pump trucks, the hybrid pump truck provided by the embodiments of the present application can continuously supply power to the power distribution device 1 because its system consists of an engine and a generator, and its working time is not limited by the battery. The hybrid pump truck provided by the embodiments of the present application integrates the functions of driving, pumping, and placing, and obtains energy through power generation by the power battery 9 or the range extender assembly 7 or the external power interface 8, etc., while saving energy, also taking into account the characteristics of power performance and pumpability sustainability.

[0040] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
