Description

  The present invention relates to a garbage truck.

  Conventionally, a dust storage box mounted on the vehicle body and having a rear opening, a dust input box connected to the rear opening of the dust storage box, and a dust input box provided in the dust input box and input into the dust input box There is known a garbage collection vehicle including a dust loading device for loading the collected dust into the dust storage box.

  This kind of garbage truck has a wide range of usage conditions for users ranging from those that operate several hours a day to those that operate all day. In addition, due to the increase in capacity of the dust container and continuous work for a long time, the load on the equipment becomes larger than before, and failure is likely to occur.

Therefore, for example, in the failure diagnosis method of Patent Document 1, the input signal and output signal of the control unit when a failure occurs are stored in the memory of the control unit, and the data in this memory can be read out by connecting to the computer from the outside. In this way, the image is processed by an external computer and compared with a value indicating a normal state, and is displayed on the screen. For example, in a garbage collection vehicle of a rotary plate type loading device, the memory when a failure occurs in the forward rotation completion switch of the conveyor panel is stored in the first to fourth phases indicating a series of loading operations. Each input signal and output signal is stored, processed by connecting an external computer, and it can be immediately judged from the comparison between this state and the normal operation state that a failure has occurred in the conveyor panel and the normal rotation completion switch. .

The display panel 32 displays maintenance information or a warning transmitted from the control unit 31 and plays a role of notifying the user. For example, the display panel 32 is also used for a back monitor mounted in the driver's seat.

-Hydraulic equipment configuration-
FIG. 8 shows a hydraulic circuit 61 of the hydraulic equipment 30 of the garbage truck according to the present embodiment. As shown in the figure, in the hydraulic device 30, four types of cylinders 9, 13, 14, and 16 are hydraulically controlled.

  Each cylinder 9, 13, 14, 16 is connected to a control valve 63 via a hydraulic pipe 61c. The control valve 63 includes a plurality of solenoid valves (not shown), and supplies hydraulic oil discharged from the hydraulic pump 51 to a desired cylinder by switching the opening and closing ports of the solenoid valves. Switching of the expansion / contraction operation of the cylinder rod is controlled, or the operation is stopped.

  The hydraulic device 30 includes a hydraulic tank 62 that stores hydraulic oil, and is configured to suck up the hydraulic oil in the hydraulic tank 62 by the hydraulic pump 51 and distribute the hydraulic oil to the supply-side hydraulic pipe 61 a and supply it to the control valve 63. ing. The hydraulic fluid that has passed through the control valve 63 flows through the recovery-side hydraulic pipe 61 b, is filtered by the return filter 64, and is then recovered by the hydraulic tank 62 again. The control valve 63 includes a pressure sensor 65 that is controlled by the main controller 50 and measures the hydraulic pressure in the hydraulic circuit 61 that is the main circuit (for example, the pressure in the hydraulic pipe 61a). In addition, the control valve 63 includes a pressure switch 66 that reacts when a specific part (for example, the swing cylinder 14) exceeds a predetermined hydraulic pressure. In addition, an oil temperature sensor 67 that detects the oil temperature toward the hydraulic tank 62 is provided in front of the return filter 64.

-Action of control unit-
The main controller 50 controls the power take-out device 52, the dust loading device 20, the discharge device 18, etc., each time the operation time of the power take-out device 52, the operation time and cycle number of the dust load device 20, the discharge device 18. The operation time and the number of operations are transmitted to the control unit 31 and stored.

  Further, the detected pressure value is transmitted from the pressure sensor 65 to the control unit 31. As a result, the number of times the hydraulic pressure exceeds a predetermined value is counted.

  Further, the pressure switch 66 reacts when the pressure exceeds a predetermined level, and a signal is transmitted to the control unit 31. As a result, the number of actuations of the pressure switch 66 is counted.

  Further, the oil temperature detected by the oil temperature sensor 67 is transmitted to the control unit 31. Thus, the oil temperature rise frequency and the peak value of the oil temperature are recorded.

  The control unit 31 collects the data indicating the operation status of the hydraulic equipment 30 that has been transmitted, calculates and determines whether maintenance information or a warning should be transmitted. In other words, when the operating status is severe, the replacement timing and grease upgrade timing are shortened, and when the operating status is moderate, the replacement timing etc. is lengthened. When this happens, the information on the display panel 32 is displayed to notify the user.

  Specifically, since the power take-out device 52 transmits the driving force of the engine of the garbage truck 1 to the hydraulic equipment 30, the operating time of the hydraulic equipment 30 is detected by detecting the operation time of the power take-out device 52. Is calculated. For this reason, the operation time of the power take-out device 52 (for example, the on time of the main power supply of the power take-out device 52) is monitored by the control unit 31, whereby the general operating status of the hydraulic device 30 is determined. Based on this information, it is possible to determine the replacement timing of periodic replacement parts and the timing of grease up of sliding parts, and when parts replacement or grease up is necessary, the parts that need to be replaced, the places where lubrication or lubrication is required, A periodic inspection instruction or the like is displayed on the display panel 32. When the control unit 31 determines that the operation time of the power take-out device 52 has continued for a long time, the control unit 31 determines that an overload condition has occurred and displays an operation restriction, thereby recognizing that the user is in an overload operation. In addition, further overloading is avoided.

  Further, in order to monitor in detail, the control unit 31 monitors the number of cycles and the operation time of the dust loading device 20, and the dust loading device according to the number of cycles of the dust loading device 20 and the length of the operation time. The replacement timing and grease up timing of the regular replacement parts of the hydraulic parts such as the slide cylinder 13 and the swing cylinder 14 that drive the drive 20 are judged. It displays on 32 and notifies a user. This prevents failure. Further, when the number of cycles of the dust loading device 20 is too large or the operation time continues continuously, the control unit 31 determines that the load is overloaded and displays an operation restriction display on the display panel 32. Thus, an overload operation by the user is avoided.

  Further, by monitoring the number of operations of the discharge device 18, for example, the number of reciprocations of the discharge cylinder 16 with the control unit 31, the hydraulic parts of the discharge cylinder 16 that drives the discharge device 18 in accordance with the operation status of the discharge device 18 are regularly used. The replacement timing of replacement parts and the timing of grease up of the sliding part are judged, and when parts replacement or grease up is necessary, the fact is displayed on the display panel 32 to prevent the discharge device 18 from being broken. The

  Further, by monitoring the number of times the pressure switch 66 of the control valve 63 reacts when the hydraulic pressure exceeds a predetermined value or the number of times the hydraulic pressure detected by the pressure sensor 65 exceeds the predetermined value, the control unit 31 monitors the case. Since the service life of the hydraulic equipment 30 is also shortened, the replacement timing or grease up timing of the periodic replacement parts of the hydraulic equipment 30 is judged according to the operating status of the hydraulic equipment 30 and the parts need to be replaced or greased up. Is displayed on the display panel 32. Further, when the number of times the hydraulic pressure exceeds a predetermined value is excessive, the control unit 31 determines that the hydraulic pressure is overloaded, and displays an operation restriction display on the display panel 32, thereby avoiding the overload operation.

  When the oil temperature detected by the oil temperature sensor 67 exceeds the predetermined value or the limit value is monitored by the control unit 31 and the oil temperature rises many times, the service life of the hydraulic equipment 30 Since the period will also be shortened, the replacement timing and grease up timing of the periodic replacement parts of the hydraulic equipment 30 will be judged according to the operating status of the hydraulic equipment 30, and if the parts replacement or grease up is necessary, this will be indicated Display on the panel 32. When the limit value is exceeded, the control unit 31 determines that the state is an overload state, and displays an operation restriction display on the display panel 32, thereby avoiding an overload operation.

  As described above, when the user sees the maintenance information or the alarm displayed on the display panel 32, it is possible to easily identify the time when the hydraulic device 30 needs to be replaced or greased, so that the failure is prevented. Further, by giving a warning to the user that the vehicle is overloaded or in front of the overloaded operation based on the operating status, the overloaded operation is reliably avoided. Moreover, inadequate vehicle management can be prevented by determining the operating status so that the load is not biased to a specific vehicle.

-Effect of the embodiment-
Therefore, according to the garbage collection vehicle 1 according to the present embodiment, the control unit 31 collects the operation status of the hydraulic device 30 and calculates it so as to notify the user of maintenance information or warning, so that the operation status is adjusted.
