[0033] Cleaning trucks, as common municipal maintenance equipment, are widely used in urban road cleaning, green space maintenance, and other scenarios. Their main structure includes a water tank, cleaning devices, and a lifting platform to carry operators and related equipment. With the acceleration of urbanization and increasingly stringent requirements for environmental cleanliness, the functions of cleaning trucks have become increasingly diversified, expanding from simple road sprinkling and sweeping to the cleaning and maintenance of facilities at heights. During actual operation, factors such as uneven ground, vehicle movement, and unstable hydraulic system pressure can easily cause the lifting platform to tilt. Especially when performing high-altitude operations, even slight angular deviations can pose serious safety risks. Once tilting occurs, it can not only threaten the safety of personnel and equipment on the platform but also affect the successful completion of the entire cleaning task.

[0034] Therefore, ensuring the stability of cleaning trucks under various complex working conditions is crucial for protecting the safety of operators. The safety and stability of cleaning trucks has become one of the most pressing issues to be addressed in the industry.

[0035] Please refer to Figures 1-4 This embodiment provides a cleaning vehicle 100, which can effectively improve the technical problems mentioned above. It can detect the tilt angle of the lifting platform 10 during the cleaning operation, thereby ensuring the safety and stability of the cleaning vehicle 100.

[0036] The cleaning vehicle 100 includes a vehicle body 60, a water tank 70, a lifting platform 10, and a tilt sensor 20. The lifting platform 10 is installed on the vehicle body 60, specifically in the middle of the vehicle body 60. The lifting platform 10 can move with the vehicle body 60 and can carry operators and move vertically, allowing operators to clean facilities at heights. A water spray frame and a fixed-point cleaning component 101 are provided at the head of the vehicle body 60. The water spray frame and the fixed-point cleaning component 101 are connected to the water tank 70 for fixed-point water spraying cleaning. The water tank 70 is installed on the vehicle body 60 and is used to store and provide water for cleaning, ensuring that the cleaning vehicle 100 has sufficient water for cleaning. The tilt sensor 20 is installed on the top of the lifting platform 10 to detect the tilt angle of the lifting platform 10, thereby ensuring the safety of operators on the lifting platform 10.

[0037] It should be noted that the tilt sensor 20 installed on the lifting platform 10 can detect the tilt angle of the lifting platform 10 in real time, which helps to monitor the attitude of the lifting platform 10 in real time. Furthermore, installing the tilt sensor 20 on the top of the lifting platform 10 allows for direct and rapid measurement of the angle change of the lifting platform 10 relative to the horizontal plane. The detected angle change is more accurate and timely, ensuring the safety and stability of the cleaning vehicle 100.

[0038] In this embodiment, the cleaning vehicle 100 also includes a controller, which is connected to the tilt sensor 20 and the lifting platform 10. The tilt sensor 20 is used to output a tilt signal to the controller when the tilt angle of the lifting platform 10 exceeds a preset angle. The controller is used to control the lifting platform 10 to stop lifting based on the tilt signal, that is, the controller is used to control the lifting platform 10 to stop rising or to control the lifting platform 10 to descend based on the tilt signal.

[0039] Specifically, the preset angle is 4°-5°. In this embodiment, the preset angle is 5°. In other embodiments, the preset angle can be adjusted according to the actual working conditions of the lifting platform 10, and the preset angle can be 4°, 4.5°, etc., without specific limitation here.

[0040] During the ascent of the lifting platform 10, the tilt sensor 20 detects the tilt angle of the lifting platform 10 in real time. If the tilt sensor 20 detects that the tilt angle of the lifting platform 10 relative to the horizontal plane is greater than 5°, the tilt sensor 20 outputs a tilt signal representing the tilt angle to the controller. After receiving the tilt signal from the tilt sensor 20, the controller controls the lifting platform 10 to stop rising.

[0041] Of course, in other embodiments, the tilt sensor 20 can be connected to an external audible and visual alarm. After receiving the tilt signal from the tilt sensor 20, the audible and visual alarm will sound an alarm, and then the lifting platform 10 will be manually controlled to stop rising.

[0042] Specifically, the lifting platform 10 includes a support platform 11, a guardrail 12, and a lifting mechanism 13. The lifting mechanism 13 is located at the bottom of the support platform 11 and is used to drive the support platform 11 to move up and down. The guardrail 12 is arranged along the circumference of the support platform 11 and is located at the top of the support platform 11, surrounding the edge of the support platform 11. An angle sensor 20 is installed on the top of the guardrail 12. The guardrail 12 includes multiple layers of railings, which are arranged at intervals along the vertical direction. The angle sensor 20 is installed on the uppermost railing.

[0043] It should be noted that the tilt sensor 20 includes a sensor body 21 and a sensor mounting bracket 22. The sensor mounting bracket 22 is connected to the guardrail 12, and the sensor body 21 is connected to the sensor mounting bracket 22. The sensor body 21 is used to detect the tilt angle of the lifting platform 10. The sensor mounting bracket 22 and the guardrail 12 are detachably connected, and the sensor mounting bracket 22 and the sensor body 21 are detachably connected.

[0044] In this embodiment, the sensor mounting bracket 22 includes a bracket body 221 and U-bolts 222. The sensor body 21 is fixed to the sensor mounting bracket 22 by bolts, and then the U-bolts 222 are used to fix the sensor mounting bracket 22 to the uppermost railing. Of course, other methods such as bolts can also be used to fix the sensor mounting bracket 22 to the uppermost railing, and no specific limitation is made here.

[0045] More specifically, after installing the tilt sensor 20 on the guardrail 12, the sensor body 21 is leveled. Specifically, the lifting platform 10 is lowered to its lowest position, ensuring that the cleaning vehicle 100 is on a flat surface. The sensor body 21 has three leveling screws. The position of the air bubbles on the sensor body 21 is observed, and the leveling of the sensor body 21 is achieved by adjusting the tightness of the three leveling screws, thus ensuring the accuracy of the data from the sensor body 21 during operation.

[0046] Furthermore, the sensor body 21 can be an analog sensor or a digital sensor, without any specific limitation.

[0047] It should also be noted that the lifting mechanism 13 includes a driver 131 and a scissor arm 132. The support platform 11 is located on top of the scissor arm 132. The guardrail 12 is connected to the support platform 11. The driver 131 is connected to the scissor arm 132 and is used to drive the scissor arm 132 to extend and retract in the vertical direction, thereby driving the support platform 11 to rise and fall in the vertical direction. The top of the support platform 11 and the scissor arm 132 are detachably connected by bolts. The scissor arm 132 includes multiple telescopic arms, which are arranged crosswise in the vertical direction and hinged sequentially.

[0048] Of course, in other embodiments, a folding arm or a straight arm may be used instead of the scissor arm 132 for operation, and no specific limitation is made here.

[0049] In this embodiment, the actuator 131 is a hydraulic cylinder. The hydraulic cylinder drives the scissor arm 132 to rise and fall, thereby causing the support platform 11 to rise and fall.

[0050] Furthermore, the cleaning vehicle 100 also includes an operation box 30, which is installed on the guardrail 12 and electrically connected to the drive unit 131. The operation box 30 is used to control the start and stop of the drive unit 131. The operation box 30 is mounted on an operation box mounting bracket 31, which is fixed to the top of the guardrail 12 by U-bolts.

[0051] In this embodiment, the tilt sensor 20 and the operation box 30 are located on the same side of the guardrail 12.

[0052] Furthermore, the cleaning vehicle 100 also includes a water pipe 40 and a cleaning component 50. The outlet of the water pipe 40 is connected to the cleaning component 50. The water pipe 40 is detachably mounted on the guardrail 12, and the water pipe 40 and the wire 201 of the tilt sensor are staggered. The cleaning component 50 is a spray gun, and the water pipe 40 is a high-pressure water hose. The water pipe 40 is connected to a water tank 70, and the inlet of the water pipe 40 is also connected to the water tank 70. The water pipe 40 can draw water from the water tank 70 into the cleaning component 50 for cleaning.

[0053] In this embodiment, in order to facilitate the neat management of the wiring harness on the lifting platform 10, the water pipe 40 is fixed by the cable tie rod 80 and cable ties. The cable tie rod 80 is welded to the guardrail 12, and the water pipe 40 is fixed to the front side of the guardrail 12 by the cable tie rod 80 and cable ties. This can avoid the safety hazards that may be caused by the water pipe 40 being loose, and can effectively organize the water pipe 40, making the layout on the guardrail 12 more tidy.

[0054] It should be noted that in this embodiment, the front side of the guardrail 12 is the side of the guardrail 12 closer to the front of the vehicle, and the rear side of the guardrail 12 is the side of the guardrail 12 closer to the rear of the vehicle.

[0055] Furthermore, the cleaning vehicle 100 also includes a multi-port assembly 90, which is installed on the side of the guardrail 12 near the rear of the vehicle and mounted at the top center of the guardrail 12 via a pipe bracket 901. The multi-port assembly 90 is located between the control box 30 and the tilt sensor 20. The multi-port assembly 90 integrates the wires 201 of the tilt sensor and 301 of the control box, and runs along the rear side of the guardrail 12, to the bottom of the lifting platform 10, and then around to the front side of the guardrail 12 for securing with cable ties 80 and cable hooks.

[0056] Specifically, the cleaning vehicle 100 also includes two quick-connect female connectors, which are respectively located on both sides of the guardrail 12. These connectors are used to connect cleaning tools such as the cleaning component 50. The cleaning component 50 is connected to the outlet of the water pipe 40 via the quick-connect female connectors, and the water pipe 40 is connected to the inlet of the multi-port pipe assembly 90 via the quick-connect female connectors. The presence of quick-connect female connectors on both sides of the guardrail 12 allows for separate operations on both sides of the guardrail 12, avoiding the inconvenience of pulling on the pipes.

[0057] The cleaning cart 100 provided in this embodiment has at least the following advantages:

[0058] The tilt sensor 20 of the cleaning vehicle 100 is installed at the highest position of the lifting platform 10. The tilt sensor 20 can detect the tilt angle of the lifting platform 10 relative to the horizontal plane during its movement. The higher the lifting platform 10 rises, the greater the tilt angle of the lifting platform 10 relative to the horizontal plane. Compared with installing the tilt sensor 20 at other positions on the lifting platform 10 or installing the tilt sensor 20 on the vehicle body 60, installing the tilt sensor 20 at the highest position of the lifting platform 10 provides more accurate tilt angle data and can detect the tilt angle of the lifting platform 10 the fastest, ensuring that the lifting platform 10 can be stopped from rising at the first time. This improves the safety during use and better protects the safety of the operators on the lifting platform 10.

[0059] The water pipes 40 and electrical wiring harnesses of the cleaning truck 100 are staggered on both sides of the lifting platform 10, making the overall appearance of the cleaning truck 100 more aesthetically pleasing and avoiding the risk of wire wear.

[0060] In summary, this utility model embodiment provides a cleaning vehicle 100, which includes a vehicle body 60, a lifting platform 10, and a tilt sensor 20. The lifting platform 10 is installed on the vehicle body 60, and the tilt sensor 20 is installed on the top of the lifting platform 10 for detecting the tilt angle of the lifting platform 10. When the cleaning truck 100 is in operation, the lifting platform 10 can carry operators and move vertically to clean and maintain facilities at height. An inclination sensor 20 is installed on the lifting platform 10, which can detect the tilt angle of the lifting platform 10 in real time, helping to monitor its posture. Furthermore, installing the inclination sensor 20 on the top of the lifting platform 10 allows for direct and rapid measurement of the angle change of the lifting platform 10 relative to the horizontal plane, resulting in more accurate and timely detection. Moreover, installing the inclination sensor 20 at the highest point of the lifting platform 10 means that its detected angle value includes the deformation angle of the lifting platform 10 during movement; the greater the height, the greater the deformation angle. The angle value detected by the inclination sensor 20 is more accurate than when it is installed on the vehicle body 60, ensuring the safety and stability of the cleaning truck 100.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
