Description

Technical Field

[0001] The utility model relates to a vehicle-mounted power system and a semi-trailer, belonging to the field of vehicle transportation equipment. Background Art

[0002] Currently, most semi-trailers with unloading functions are equipped with working devices composed of hydraulic components. The power source of the hydraulic system is mainly the power output interface modified on the gearbox of the semi-trailer tractor, and the power connection with the hydraulic system is established by installing a power take-off. This solution has the following shortcomings:

[0003] 1) Different types of gearboxes require different types of power take-offs, and their technical parameters are also different, so it is impossible to select a unified model.

[0004] 2) The working status of the power take-off needs to be controlled by modifying the switch in the cab. The operation process is cumbersome and there is often a problem of gear jostling due to the inability to hang up the power take-off.

[0005] 3) The power speed output by the power take-off is mainly controlled by the driver manipulating the gear of the transmission and by increasing or decreasing the throttle. The driver's operating habits vary from person to person and from time to time. There is no fixed standard value, which will lead to unstable hydraulic power output of the working device and reduce the service life of the hydraulic components.

[0006] 4) When separating the semi-trailer from the tractor, the hydraulic pump and hydraulic pipeline connected to the power take-off need to be removed, which is time-consuming and labor-intensive.

[0007] In addition, most of the current semi-trailers are powered by the batteries of the semi-trailer tractors. When the semi-trailers need to be equipped with high-voltage, high-power electrical equipment, such as heaters, vibrators, etc., the batteries cannot meet the usage requirements. Summary of the Invention

[0008] In response to the problems existing in the above-mentioned prior art, the present invention provides a vehicle-mounted power system and a semi-trailer. The vehicle-mounted power system can be connected to the working device configured on the semi-trailer to provide a power source for the hydraulic system, thereby replacing the power output interface modified from the gearbox of the semi-trailer tractor to obtain power.

[0009] In order to achieve the above-mentioned purpose, the utility model adopts a vehicle-mounted power system, including a diesel engine, a generator, a hydraulic pump, a hydraulic cylinder, a cylinder control valve and a diesel tank. The diesel engine is connected to the generator, the hydraulic pump is connected to the diesel engine, the hydraulic pump is connected to the cylinder control valve and the hydraulic cylinder through a hydraulic oil pipe, and the diesel tank is connected to the diesel engine through a diesel pipe.

[0010] In some embodiments, the diesel engine is connected to a radiator.

[0011] In some embodiments, the cylinder control valve includes a manual control lever for manually controlling the extension and retraction of the hydraulic cylinder.

[0012] In some embodiments, the cylinder control valve is connected to a solenoid valve for remotely controlling the extension and retraction of the hydraulic cylinder.

[0013] The second aspect of the present invention further provides a semi-trailer on which the vehicle-mounted power system is installed.

[0014] In some embodiments, the semi-trailer is provided with a plurality of mounting brackets, including a first mounting bracket located at the front end of the semi-trailer and a second mounting bracket located in the middle of the semi-trailer;

[0015] A slideway is provided at the bottom of the first mounting bracket, and oblong holes are provided on both sides. The first mounting bracket is fixedly connected to the semi-trailer by bolts, and the second mounting bracket is fixedly connected to the semi-trailer by bolts.

[0016] In some embodiments, the diesel engine and generator are mounted on the first mounting bracket, and the diesel tank is mounted on the second mounting bracket.

[0017] In some embodiments, one end of the hydraulic cylinder is connected to the semi-trailer, and the other end is connected to the first mounting bracket.

[0018] Compared to existing technologies, the semi-trailer of this utility model features a forward-and-backward movable onboard power system, which can power the hydraulic system installed on the semi-trailer without installing a power take-off on the tractor head. This makes connecting the semi-trailer to the tractor simple and quick, and the hydraulic system operates without the need for a power take-off, making operation convenient, safe, and reliable. The diesel engine, generator, and other components can be moved forward and backward by the propulsion of the hydraulic cylinder, making the structure more compact and aesthetically pleasing while also improving maintenance ease.

[0027] Example 1

[0028] like Figure 1 、 Figure 2 As shown, a vehicle-mounted power system includes a diesel engine 3, a generator 4, a hydraulic pump 5, a hydraulic cylinder 6, a cylinder control valve 7 and a diesel tank 8;

[0029] The diesel engine 3 is connected to the generator 4, and the hydraulic pump 5 is connected to the diesel engine 3. The hydraulic pump 5 is driven by the output port on the diesel engine 3. The hydraulic pump 5 is connected to the cylinder control valve 7 and the hydraulic cylinder 6 through the hydraulic oil pipe 10. The cylinder control valve 7 can control the extension and retraction of the hydraulic cylinder 6. The diesel tank 8 is connected to the diesel engine 3 through the diesel pipe 9 to provide fuel for the diesel engine 3.

[0030] In some embodiments, the diesel engine 3 is connected to a radiator 12 to provide heat dissipation for media such as engine oil and hydraulic oil.

[0031] In some embodiments, the cylinder control valve 7 is provided with a manual control lever, through which the movement of the hydraulic cylinder 6 can be controlled. In addition, the cylinder control valve 7 is connected to a solenoid valve, which can control the movement of the hydraulic cylinder 6 by remote control.

[0032] Example 2

[0033] like Figure 1 、 Figure 2 As shown, the present invention also provides a semi-trailer, which is equipped with the on-board power system 2. The semi-trailer 1 is provided with a plurality of mounting brackets for mounting components of the on-board power system 2;

[0034] The vehicle-mounted power system 2 includes a diesel engine 3, a generator 4, a hydraulic pump 5, a hydraulic cylinder 6, a cylinder control valve 7, and a diesel tank 8. The diesel engine 3 is directly connected to the generator 4, which can provide high-power electrical output. The diesel tank 8 is connected to the diesel engine 3 through a diesel pipe 9 to provide fuel for the diesel engine 3.

[0035] The hydraulic pump 5 is connected to the output port of the diesel engine 3, and then connected to the cylinder control valve 7 and the hydraulic cylinder 6 through the hydraulic oil pipe 10. The cylinder control valve 7 can control the extension and contraction of the hydraulic cylinder 6.

[0036] In order to reasonably arrange the installation position, the installation bracket includes a first installation bracket 13 and a second installation bracket 15;

[0037] like Figure 3 、 Figure 4 As shown, the first mounting bracket 13 is arranged at the front end of the semi-trailer 1, and the diesel engine 3 and the generator 4 are mounted on the first mounting bracket 13. A slide 13-1 is provided at the bottom of the first mounting bracket 13 to facilitate forward and backward sliding. Oblong holes 13-2 are provided on both sides of the first mounting bracket 13.

[0039] One end of the hydraulic cylinder 6 is connected to the semi-trailer 1, and the other end is connected to the first mounting bracket 13. The forward and backward movement of the first mounting bracket 13 is controlled by the extension and contraction of the hydraulic cylinder 6. Specifically, when the diesel engine 3 or generator 4 needs to be moved, the bolts 14 in the oblong holes 13-2 are first loosened. Then, the hydraulic cylinder 6 is driven by a manual control lever or remote control to move the first mounting bracket 13 along the slide 13-1 at its bottom to the front end of the semi-trailer 1. After it is moved into place, the bolts 14 are re-tightened. In addition, the first mounting bracket 13 and the second mounting bracket 15 both adopt a square frame structure, which provides high support stability.

[0040] This semi-trailer, equipped with a forward-and-backwards movable onboard power system, can power the semi-trailer's hydraulic system without installing a power take-off on the tractor head.
