Description

Technical Field

[0001] The utility model relates to the field of compressed garbage trucks, in particular to a compressed garbage truck mounting system. Background Art

[0002] Compacted garbage trucks are an important part of urban sanitation, used to collect and transport urban garbage. In the process of collecting garbage, the scraper on the vehicle will encounter garbage of different hardness, especially when encountering hard objects such as construction waste. Traditional scrapers lack effective protection measures, resulting in excessive pressure on the cylinder, which may cause oil leakage, deformation of the scraper contact surface, and even cylinder breakage, which seriously affects the service life and operation safety of the vehicle. Summary of the invention

[0003] In view of the shortcomings of the prior art, the utility model provides a compression garbage truck mounting system. The utility model uses an angle sensor to monitor the scraper movement angle and the body inclination. When the scraper encounters resistance, it can automatically take protective measures. At the same time, when the body inclination reaches a certain threshold, it limits the operation or adjusts the body balance, thereby improving the operation safety and extending the service life of the vehicle.

[0004] The technical solution of the utility model is: a compression garbage truck upper installation system, including a control unit, the control unit is connected with angle sensor one and angle sensor two, and is characterized in that: the control unit respectively drives the tail plate cylinder solenoid valve and the scraper cylinder solenoid valve to act by collecting data from angle sensor one and angle sensor two, the angle sensor one is fixed on the scraper or installed near the scraper movement joint, and is used to collect the vehicle's scraper initial angle and the real-time feedback angle when the scraper moves; the angle sensor two is fixed on the vehicle body beam; when the inclination angle of the angle sensor two is too large, the vehicle is prohibited from performing garbage unloading operations or performing opposite movements to prevent the vehicle from tipping over; the angle sensor two subtracts the data from the angle sensor one to calculate the scraper angle data change speed, and when the movement speed is 0, the scraper stops moving or performs the opposite movement to protect.

[0005] According to the compression garbage truck mounting system as described above, it is characterized in that when the vehicle body beam is parallel to the ground, the reading of the angle sensor 2 is set to zero.

[0006] According to the compression garbage truck mounting system as described above, it is characterized in that the real-time movement angle of the scraper is obtained by subtracting the horizontal angle of the angle sensor 2 data from the angle sensor 1 data.

[0007] According to the compression garbage truck upper mounting system as described above, it is characterized in that the scraper angle data change speed is calculated based on the data of angle sensor two minus the data of angle sensor one, and it is estimated whether the scraper encounters resistance based on the scraper angle data change speed, so as to intervene, such as through reversal or stopping for protection.

[0008] The utility model has the beneficial effects of: making the vehicle balanced to ensure the safety of the operation and prolonging the service life of the vehicle. According to the speed of change of the scraper angle data, it is estimated whether the scraper encounters resistance, so as to intervene, such as by reversing or stopping for protection, and prolonging the service life of the hydraulic system mounted on the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0010] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0011] like Figure 1 As shown, a compression garbage truck upper mounting system of the utility model includes an upper mounting control unit,

[0012] The control unit is connected to the angle sensor 1, the angle sensor 2, and the scraper in place proximity switch. The scraper in place proximity switch is fixed on the active joint of the scraper in place, and is used to judge whether the scraper and the hopper are in place. The control unit is a CPU control unit. The control unit drives the tail plate cylinder solenoid valve and the scraper cylinder solenoid valve to act respectively by collecting the data of the angle sensor 1 and the angle sensor 2. The angle sensor 1 is fixed on the scraper active joint, and is used to collect the movement angle of the scraper relative to the ground, that is, to collect the movement angle of the scraper relative to the ground. The angle sensor 2 is fixed on the vehicle body beam. When the vehicle body beam is parallel to the ground, the reading of the angle sensor 2 is set to zero, that is, it is used to collect the inclination angle of the vehicle body relative to the ground. In this way, the real-time movement angle of the scraper can be obtained by subtracting the horizontal angle of the angle sensor 2 data from the angle sensor 1 data. In the actual operation process, the angle sensor 2 is in an unlevel state, such as negative two degrees, then the angle measured by the angle sensor 1 minus two degrees is the angle between the scraper and the beam, and the angle sensor 2 directly obtains the inclination angle of the vehicle body. When the inclination angle is too large, the vehicle is prohibited from unloading garbage or doing the opposite movement to prevent the vehicle from tipping over. Therefore, as a further solution of the utility model, when the vehicle body beam is parallel to the ground, the position readings of angle sensor 1 and angle sensor 2 are both made zero by adjusting the installation position, which facilitates measurement and calculation.

[0013] The utility model calculates the scraper angle data change speed based on the data of angle sensor 2 minus angle sensor 1, and estimates whether the scraper encounters resistance based on the scraper angle data change speed, so as to intervene. For example, when the movement angle change is small or 0 and the scraper is in place and the proximity switch does not detect a signal, it is predicted that the scraper may face resistance, and the system will stop the scraper from continuing to scrape or perform a reverse opening action to avoid the hydraulic system working in a pressure-holding state for a long time.

[0014] For example, when the movement speed is 0, it means that the scraper is in an obstructed state. In this case, it is protected by stopping or taking the opposite action. The function of the second angle sensor is to obtain the inclination angle of the vehicle body. When the inclination angle is too large, the vehicle is prohibited from unloading garbage or taking the opposite action to prevent the vehicle from tipping over. The utility model can pre-measure the rate of change of the scraper angle data during normal operation. For example, it is possible to measure or calculate the rate of change of the angle data when there is no resistance or the resistance is within the normal range. If the rate of change of the angle data is less than this value during actual operation, it is considered that the pressure may be too large to damage the hydraulic system and the mechanical structure of the scraper itself. The purpose of the protective device is achieved by controlling the scraper cylinder solenoid valve to move the scraper in the opposite direction.

[0015] At the same time, the angle of the angle sensor 2 of the utility model can determine the inclination angle of the vehicle body beam. When the inclination angle reaches a certain threshold, the vehicle operation is restricted or the tailgate cylinder is controlled to descend by controlling the tailgate cylinder solenoid valve to balance the vehicle to ensure the safety of the operation while extending the service life of the vehicle.

[0016] like Figure 1 As shown, the utility model further comprises a voice alarm unit or an audible and audible alarm unit. When it is detected that the scraper is in an obstructed state or the inclination angle of the beam is too large, the voice alarm unit or the audible and audible alarm unit sends out an alarm message.

[0017] The utility model provides a garbage truck upper mounting system, which uses two angle sensors to calculate the scraping angle of the scraper. When the motion angle data fed back by the scraper sensor changes close to 0 within a cycle, it means that the scraper cylinder is subject to resistance. At this time, the upper mounting control unit is connected to the hydraulic action to make it do the opposite action or suspend its interference to protect the entire hydraulic system and even the mechanical structure from being damaged. At the same time, the data of sensor 2 can be used to determine the inclination angle of the vehicle body beam. When the inclination angle reaches a certain threshold, the vehicle operation is restricted or the tailgate cylinder is controlled to descend to balance the vehicle.
