Description

Technical Field

[0001] The utility model belongs to the field of mobile power generation devices, and in particular relates to a multi-purpose unit equipment capable of generating electricity and moving. Background Art

[0002] Internal combustion engines burn fuel to generate high-temperature and high-pressure gases, which are then converted into mechanical energy to propel the vehicle forward. Internal combustion engines can meet the power needs of various construction machinery (such as trucks, excavators, bulldozers, etc.) and are a widely used power source in modern industry. Internal combustion engines used for traveling are called "traveling machines" in the industry.

[0003] Internal combustion engines also play an important role in industrial production. Many industrial equipment, such as generators, require internal combustion engines to provide power. Generator sets use internal combustion engines to drive generators, converting the energy generated by fuel combustion into electrical energy to provide electricity for factories, houses, etc. Internal combustion engines used for power generation are called "land-based power generation internal combustion engines" in the industry.

[0004] Traditional engineering machinery equipment generally uses a traveling machine as a power source to drive the vehicle for external operations. If power is needed during operation, a generator set is required, such as an environmental dust suppression vehicle, a welding engineering vehicle, a mobile power vehicle, etc. Generator sets and traveling machines are very important equipment in modern industry. They play a key role in the fields of energy conversion and power supply as well as the field of travel. If power is needed for engineering machinery operations, a generator set is required, which will result in two independent internal combustion engines on one engineering vehicle, which undoubtedly greatly increases the equipment cost, operation and maintenance cost, maintenance difficulty, and overall equipment weight.

[0005] Combining the generator set with the traveling machine, an engineering vehicle only needs one internal combustion engine. For example, the tracked power supply vehicle disclosed in CN200420013364.5 organically combines the generator with the carrier, and its internal combustion engine provides power for both the generator and the traveling. The power of the internal combustion engine is transmitted to the transmission through the transmission clutch, and the driving wheel connected to the transmission output shaft drives the track to run on the ground. This method directly converts the power of the internal combustion engine into mechanical energy to drive the track to run. Compared with hydraulic drive, the torque obtained when mechanical energy drives walking is limited, and it is difficult to apply to scenes that require large torque walking, such as swamps, rivers and other muddy areas, and mechanical energy drive cannot be applied to scenes that require hydraulic drive, such as bucket arms, lifting platforms, bulldozers and other scenes.

[0011] In a preferred embodiment of the present utility model, a throttle valve for adjusting the flow rate of hydraulic oil in the third pipeline is provided on the third pipeline.

[0012] The above technical solution, when in power generation mode at a constant speed of 1500 rpm, uses a throttle valve to adjust the flow of the third pipeline to change the running speed of the crawler track, and is used for power generation mode plus hydraulic mode operation.

[0013] In a preferred embodiment of the present utility model, the oil outlet of the hydraulic pump is also connected to the oil return port of the hydraulic oil tank through a fourth pipeline provided with a relief valve.

[0014] The above technical solution sets the working pressure output by the hydraulic pump or limits its maximum working pressure by setting a relief valve, thereby preventing overload and improving the safety of the hydraulic system.

[0020] The above technical solution can conveniently monitor the status of the unit equipment remotely through the monitoring module, and the distribution box is connected to the monitoring module to extend the control circuit of the internal combustion engine and the generator set to the cab.

[0021] In another preferred embodiment of the present invention, the monitoring module is installed in the cab via a height-adjustable bracket having a universal rotating joint.

[0022] The above technical solution, by providing a height adjustment bracket, can adjust the height and angle of the monitoring module for different groups of people, thereby improving practicality.

When the power generation mode / walking mode selection switch outputs a power generation mode signal, the mode control end of the internal combustion engine obtains a first signal to enter the power generation mode, and when the power generation mode / walking mode selection switch outputs a walking mode signal, the mode control end of the internal combustion engine obtains a second signal to enter the walking mode.

[0024] The above technical solution, by setting up a controller and a power generation mode / walking mode selection switch, people can operate the power generation mode / walking mode selection switch to adjust the speed of the internal combustion engine to the speed corresponding to the power generation mode / walking mode.

For example, the hydraulic system can be applied to bucket arms, lifting platforms, and bulldozers by setting up multiple hydraulic cylinders to expand more functions and a wider range of operations.

[0030] 3) Two different working modes are adopted, namely, when the speed is constant at 1500 rpm in the power generation mode, the flow of the second pipeline can be adjusted by the throttle valve to change the running speed of the crawler track, which is used for power generation mode plus hydraulic mode operation; or when the internal combustion engine is at a low speed of 650-1000 rpm, the speed knob can be used to adjust the speed of the internal combustion engine to adjust the flow of the hydraulic pump for low-speed traveling.

[0031] 4) The speed knob is used to adjust the speed of the internal combustion engine at low speed, and the low-speed torque is tested, which solves the problem that the traditional "traveling machine" has convenient speed regulation but poor stability in constant speed power generation, and the problem that the generator has stable power generation but cannot adjust the speed within a large range and has no matching data. The utility model has the advantages of both.

DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "vertical", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0039] The utility model provides a unit device capable of generating electricity and traveling (hereinafter referred to as the unit device), such as Figure 1As shown, in a preferred embodiment, the unit equipment includes a vehicle body 18 with a crawler 17 installed at the bottom. The connection method between the crawler 17 and the vehicle body 18 is the existing technology and is not described in detail here. An internal combustion engine 2 is installed on the vehicle body 18, and the output shaft of the internal combustion engine 2 is coaxially connected to a generator 5 and a hydraulic pump 6. Preferably, the hydraulic pump 6 is connected to the end of the output shaft of the internal combustion engine 2. A water cooling circulation system 1 for water cooling the internal combustion engine 2 is provided on the vehicle body 18 to reduce the temperature of the internal combustion engine 2.

[0040] Among them, the generator 5 is a device that converts the mechanical energy of the internal combustion engine 2 into electrical energy. The generator 5 is connected to the distribution box 4. The generator 5 is also connected to the circuit breaker 3 to ensure the safety and reliability of the operation of the generator 5. The oil inlet of the hydraulic pump 6 is connected to the hydraulic oil tank 16 through the first pipeline 19 (the hydraulic oil tank 16 is installed on the vehicle body 18. For the convenience of observation, the hydraulic oil tank 16 part is expanded and drawn). The oil outlet of the hydraulic pump 6 is connected to the hydraulic motor 13 installed on the vehicle body 18 through the second pipeline 20. The hydraulic motor 13 is connected to the oil return port of the hydraulic oil tank 16 through the third pipeline 21. The hydraulic pump 6 drives the hydraulic motor 13 to rotate, and the output shaft of the hydraulic motor 13 is connected to the gear drive wheel 14 of the crawler 17.

[0041] During operation, the internal combustion engine 2 starts and then increases its speed to 1500 rpm, driving the generator 5 to operate and generate electricity synchronously. By setting up the distribution box 4, stable power output can be achieved, such as 400V / 50HZ power output. Power output of other voltages and frequencies can also be achieved, which can be used for equipment operations such as electric welding, heating, and water pumps for on-site use.

[0042] At the same time, the internal combustion engine 2 drives the hydraulic pump 6 to rotate, and the hydraulic pump 6 draws hydraulic oil from the hydraulic oil tank 16, pressurizes it, and then transmits it to the hydraulic motor 13 through the second pipeline 20, driving the hydraulic motor 13 to rotate. After the hydraulic motor 13 rotates, it drives the crawler 17 to run through the gear drive wheel 14, which can realize the walking function of the unit equipment. The hydraulic oil after driving the hydraulic motor 13 to rotate returns to the hydraulic oil tank 16, completing the entire hydraulic oil circulation process.

[0043] The utility model adopts a hydraulic system, which can obtain a greater torque when walking, and can arrange the various components of the hydraulic system more conveniently and flexibly. The hydraulic system can also be extended to the application of engineering equipment. For example, the hydraulic system can be applied to bucket arms, lifting platforms, and bulldozers to expand more functions by setting up multiple hydraulic cylinders; and the crawler 17 driven by the hydraulic system can be more adaptable to some muddy areas such as swamps and rivers, and the operating range is wider.

[0044] It should be noted that since most of the construction machinery equipment moves at low speeds during operation or transfer and does not require a very high speed, the internal combustion engine 2 can be set to an adjustable design with a low speed range of 650-1000 / min, and the corresponding torque data parameters at low speed are tested to match the hydraulic system, thereby maximizing the economic fuel consumption of low-speed travel through low-fuel consumption control during low-speed travel.

[0045] In another preferred embodiment, the unit equipment further includes a reversing solenoid valve 15 having four interfaces for reversing the rotation direction of the hydraulic motor 13, two interfaces of the reversing solenoid valve 15 are connected to the second pipeline 20, and the other two interfaces of the reversing solenoid valve 15 are connected to the third pipeline 21. The specific structure and connection method of the reversing solenoid valve 15 are prior art and are not described in detail here. The reversing solenoid valve 15 can change the flow direction of the hydraulic oil entering the hydraulic motor 13 by reversing, so as to change the rotation direction of the hydraulic motor 13, so as to change the rotation direction of the gear drive wheel 14, and then change the walking direction of the crawler 17, so that the unit equipment can move forward or backward.

[0046] For example, when the hydraulic motor 13 needs to rotate forward, the hydraulic oil output by the hydraulic pump 6 enters the reversing solenoid valve 15 through the first section of the second pipeline 20, is transported by the second section of the second pipeline 20, and enters through the first oil port of the hydraulic motor 13; after being discharged from the second oil port of the hydraulic motor 13, it enters the reversing solenoid valve 15 through the first section of the third pipeline 21, and is transported to the hydraulic oil tank 16 by the second section of the third pipeline 21. When the hydraulic motor 13 needs to be reversed, the hydraulic oil output by the hydraulic pump 6 enters the reversing solenoid valve 15 through the first section of the second pipeline 20, is transported by the first section of the third pipeline 20, and enters through the second oil port of the hydraulic motor 13; after being discharged from the first oil port of the hydraulic motor 13, it enters the reversing solenoid valve 15 through the second section of the second pipeline 20, and is transported to the hydraulic oil tank 16 by the second section of the third pipeline 21.

[0047] In another preferred embodiment, a throttle valve 7 for adjusting the flow rate of hydraulic oil in the third pipeline 21 is provided on the third pipeline 21. The throttle valve 7 is arranged between the hydraulic motor 13 and the reversing solenoid valve 15, that is, it is arranged on the first section of the third pipeline 20. The throttle valve 7 is used to adjust the flow rate of the hydraulic oil in the third pipeline 21 to change the rotation speed of the hydraulic motor 13, thereby adjusting the running speed of the track 17.

[0048] In another preferred embodiment, the oil outlet of the hydraulic pump 6 is also connected to the oil return port of the hydraulic oil tank 16 through a fourth pipeline 22 provided with an overflow valve 8. The overflow valve 8 is used to adjust the working pressure discharged from the hydraulic pump 6 to the second pipeline 20 or to limit its maximum working pressure to prevent overload.

[0049] In another preferred embodiment, the front end of the vehicle body 18 has a cab 9, and a monitoring module 11 for displaying the status of the unit equipment is provided in the cab 9, so that the status of the unit equipment can be easily monitored remotely through the monitoring module 11; the power supply end of the distribution box 4 is electrically connected to the monitoring module 11 to supply power to it, and the control circuit of the internal combustion engine 2 and the generator 5 is extended to the cab 9. Preferably, the monitoring module 11 is installed in the cab 9 through a height adjustment bracket 12 with a universal rotating joint, and the height and angle of the monitoring module 11 can be adjusted for different groups of people.

[0050] In another preferred embodiment, the unit equipment further includes a controller and a power generation mode / travel mode selection switch. The controller can be built in the distribution box 4. The model of the controller can be selected from Zhongzhi HGM6110CAN-S24. The power generation mode / travel mode selection switch can be arranged in the cab 9, such as in the button box 10. The output end of the power generation mode / travel mode selection switch is connected to the mode signal input end of the controller, and the mode control output end of the controller is connected to the mode control end of the internal combustion engine 2. When the power generation mode / travel mode selection switch outputs the power generation mode signal, the mode control end of the internal combustion engine 2 obtains a first signal (such as a high level) to enter the power generation mode. When the power generation mode / travel mode selection switch outputs the travel mode signal, the mode control end of the internal combustion engine 2 obtains a second signal (such as a low level) to enter the travel mode.

[0051] Thus, by operating the power generation mode / travel mode selection switch, the rotation speed of the internal combustion engine 2 is automatically adjusted to a rotation speed corresponding to the power generation mode / travel mode.

[0052] Further preferably, the cab 9 is also provided with a button box 10 connected to the monitoring module 11, and the button box 10 is arranged in the cab 9. The button box 10 is provided with a speed knob (such as a CAN speed knob), an operation indicator light, a power generation mode / travel mode selection switch, and an emergency stop switch, so that the operation status of the unit equipment can be observed intuitively, and the operation of the unit equipment can be stopped in an emergency. The signal output end of the speed knob is connected to the speed control signal input end of the controller in the distribution box 4, and the speed signal output end of the controller is connected to the speed control end of the internal combustion engine 2.

[0053] The unit equipment has two working modes: power generation and traveling. The specific working speed of the internal combustion engine 2 in the power generation mode and the traveling mode can be set through the monitoring module 11. The power generation mode is entered by connecting the controller input port in the distribution box 4, and the traveling mode is entered by disconnecting the controller input port.

[0054] The unit equipment is started, the speed of the internal combustion engine 2 in idle mode is 650 rpm, the speed of the internal combustion engine 2 in running mode is 650-1000 rpm, and the speed of the internal combustion engine 2 in power generation mode is 1500 rpm. The speed knob can be used to achieve stepless speed regulation of the speed of the internal combustion engine 2, and the speed knob sends a speed regulation signal to the controller, and then the controller converts CAN into CAN commands that can be recognized by the ECU to regulate the speed of the internal combustion engine.

[0055] When the selection switch on the button box 10 is selected to the power generation mode, the speed of the internal combustion engine 2 automatically reaches 1500 rpm, and voltage protection, frequency protection, overcurrent protection, overpower protection, etc. are all effective; when the selection switch on the button box 10 is selected to the walking mode, the internal combustion engine 2 enters the calibrated low speed of 650 rpm-1000 rpm, and there is no power protection and low speed protection.
