Description

Technical Field

[0001] This utility model belongs to the technical field of road cleaning vehicles and relates to a cleaning device for a cleaning vehicle. Background Technology

[0002] To ensure the aesthetics and cleanliness of city roads, regular cleaning is necessary. Due to their compact size, flexibility, and high maneuverability, small electric cleaning vehicles are widely used in city road cleaning. However, the width of the city roads to be cleaned varies. This means that when the electric cleaning vehicle encounters narrow roads, the width of the cleaning device at the front of the vehicle is greater than the width of the road, causing the cleaning device to obstruct the vehicle's movement. In addition, when there are obstacles on the road, the low height of the cleaning device above the ground can cause it to collide with the obstacles, preventing the cleaning vehicle from moving normally. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cleaning device for a cleaning vehicle that can reduce its width and can be raised and lowered.

[0004] The objective of this utility model can be achieved through the following technical solution: a cleaning device for a cleaning vehicle, comprising:

[0005] Install components;

[0006] A lifting plate is located on one side of the mounting assembly, which is capable of driving the lifting plate to rise and fall. A spray frame is provided on the lifting plate.

[0007] A pair of water spraying components, one end of which is rotatably connected to the end of a spraying frame, and the spraying frame is further provided with a transmission component for controlling the rotation of the corresponding water spraying component relative to the spraying frame in a transverse plane.

[0008] The second cylinder has one end connected to the spray frame and the other end connected to the transmission assembly. The second cylinder is used to drive the corresponding transmission assembly to move.

[0009] In the cleaning device of the cleaning vehicle described above, each of the water spraying components can rotate relative to the transmission component, and the water spraying components are elastically connected to the transmission component.

[0010] In the cleaning device of the aforementioned cleaning vehicle, each of the transmission components includes a connecting plate, a rotating plate, a transmission angle plate, and a transmission rod. The connecting plate is connected to the spray frame, and the transmission angle plate has a first angle, a second angle, and a third angle. The first angle is hinged to the connecting plate, the second angle is hinged to the second cylinder, and the third angle is hinged to one end of the transmission rod. One end of the rotating plate is hinged to the connecting plate, and the other end of the rotating plate is hinged to an adjacent water spray component. The end of the transmission rod away from the transmission angle plate is hinged to the end of the rotating plate away from the connecting plate.

[0011] In the cleaning device of the aforementioned cleaning vehicle, each of the water spraying components includes a movable frame, on which a water spraying pipe is provided, and one end of the movable frame is hinged to a rotating plate.

[0012] In the cleaning device of the cleaning vehicle described above, an extension plate is provided on the end of the rotating plate away from the connecting plate, a vertical rod is provided between the extension plate and the rotating plate, one end of the movable frame is movably located between the extension plate and the rotating plate, and the vertical rod passes through the movable frame.

[0013] In the cleaning device of the cleaning vehicle described above, a spring is provided between the bottom surface of the extension plate and the movable frame, and a limiting plate is provided on the end face of the rotating plate away from the connecting plate, and bolts are installed on the limiting plate.

[0014] In the cleaning device of the aforementioned cleaning vehicle, one side of the movable frame abuts against one end of the bolt.

[0015] In the cleaning device of the cleaning vehicle described above, the spray frame is provided with a connecting frame inside, and the connecting frame is provided with a connecting rod for connecting the connecting plate.

[0016] In the cleaning device of the cleaning vehicle described above, the mounting assembly includes a mounting plate, and the two sides of the lifting plate are respectively hinged to the mounting plate by at least two hinge blocks. A first cylinder is hinged to the mounting plate, and the end of the first cylinder away from the mounting plate is hinged to the lifting plate.

[0017] In the cleaning device of the cleaning vehicle described above, the mounting plate is provided with at least two hook plates, and each hook plate has a hook at its top.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, when the cleaning truck is driving on a narrow road, the driver can simultaneously operate two second cylinders to drive the corresponding transmission components to rotate the corresponding water spray components inward relative to the spray frame. When the distance between the two water spray components is less than the width of the road, the second cylinders stop rotating.

[0020] 2. When an obstacle appears in front of the cleaning truck, the operator controls the installation components to raise the spray frame and lifting platform. Since the water spray components are installed at both ends of the spray frame, they will also rise synchronously with the spray frame. Once the spray frame and water spray components have risen to the predetermined height, the cleaning truck continues to move forward, and the spray frame and water spray components will not come into contact with the obstacle, allowing the cleaning truck to travel straight normally.

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1 — Figure 5 As shown, the cleaning device of the cleaning vehicle of this utility model includes an installation component 100, a lifting plate 200, a spray frame 300, a water spray component 400, a transmission component 500, and a second cylinder 310.

[0028] A lifting plate 200 is located on one side of the mounting assembly 100, which drives the lifting plate 200 to rise and fall. A spray frame 300 is mounted on the lifting plate 200. A pair of water spray components 400 are respectively located at both ends of the spray frame 300. One end of each water spray component is rotatably connected to the corresponding end of the spray frame. Both ends of the spray frame 300 are equipped with transmission components 500 for controlling the rotation of the corresponding water spray component 400 relative to the spray frame 300 in a transverse plane. One end of a second cylinder 310 is connected to the spray frame, and the other end is connected to the transmission component. The second cylinder 310 drives the corresponding transmission component. Each water spray component 400 can rotate relative to the transmission component 500, and the water spray component 400 is elastically connected to the transmission component 500. When the cleaning truck is driving on a narrow road, the driver can simultaneously operate both second cylinders 310 to drive the corresponding transmission component 500, thereby controlling the corresponding water spray component 400 to rotate inward relative to the spray frame 300. When the distance between the two water spray components 400 is less than the width of the road surface, the second cylinder 310 stops rotating. This reduces the lateral width of the cleaning device, preventing the water spray components 400 from touching the edge of the road surface during the cleaning vehicle's movement. Furthermore, when an obstacle appears on one side of the cleaning vehicle while it is traveling on the road, the water spray component 400 on that side can be rotated inwards to retract, allowing the cleaning vehicle to pass smoothly. The vehicle can pass over obstacles. In addition, when an obstacle appears in front of the cleaning truck, the installation component 100 can be controlled to raise the spray frame 300 and the lifting plate 200. Since the water spray component 400 is installed at both ends of the spray frame 300, the water spray component 400 will also rise synchronously with the spray frame 300. After the spray frame 300 and the water spray component 400 rise to the predetermined height, the cleaning truck continues to move forward, and the spray frame 300 and the water spray component 400 will not come into contact with the obstacle, so that the cleaning truck can travel straight normally.

[0029] Furthermore, during the operation of the cleaning vehicle, when the driver fails to notice an obstacle on the road and the water spray assembly 400 encounters the obstacle, because the water spray assembly 400 is elastically connected to the corresponding transmission assembly 500 and can rotate relative to the transmission assembly 500, the water spray assembly 400 is subjected to the reaction force of the obstacle, and rotates inward relative to the transmission assembly 500, thereby achieving the purpose of avoiding the obstacle. After the water spray assembly 400 passes the obstacle, it automatically resets. In this way, the damage caused by the water spray assembly 400 hitting the obstacle can be effectively reduced.

[0030] Furthermore, when the water spray assembly 400 is closed, it will also spray water on both sides of the road surface; a spray pipe 340 is installed inside the spray frame.

[0031] like Figure 1 — Figure 4 As shown, each of the transmission components 500 includes a connecting plate 510, a rotating plate 520, a transmission angle plate 530, and a transmission rod 540. The connecting plate 510 is connected to the spray frame 300. The transmission angle plate 530 has a first angle 531, a second angle 532, and a third angle 533. The first angle 531 is hinged to the connecting plate 510, the second angle 532 is hinged to the second cylinder 310, and the third angle 533 is hinged to one end of the transmission rod 540. One end of the rotating plate 520 is hinged to the connecting plate 510, and the other end of the rotating plate 520 is connected to the adjacent water spray component 4. 00 Hinged, the end of the transmission rod 540 away from the transmission angle plate 530 is hinged to the end of the rotating plate 520 away from the connecting plate 510. Each of the water spraying components 400 includes a movable frame 410. The movable frame 410 is provided with a water spray pipe 420. One end of the movable frame 410 is hinged to the rotating plate 520. The end of the rotating plate 520 away from the connecting plate 510 is provided with an extension plate 522. A vertical rod 523 is provided between the extension plate 522 and the rotating plate 520. One end of the movable frame 410 is movably located between the extension plate 522 and the rotating plate 520, and the vertical rod 523 passes through the movable frame 410.

[0032] When the cleaning truck is cleaning the road surface, the two water spray components 400 are in the open state. When the cleaning truck encounters a narrow road surface, it is necessary to control the second cylinder 310 to retract when the water spray components 400 need to be closed. Because the second corner 532 of the transmission angle plate 530 is hinged to one end of the second cylinder 310, the first corner 531 is hinged to the connecting plate 510, and the third corner 533 is hinged to one end of the transmission rod 540, the transmission angle plate 530 rotates counterclockwise around the first corner 531. At this time, the transmission angle plate 530 will drive the transmission rod 540 to move. The other end of the transmission rod 540 is hinged to one end of the rotating plate 520, and the other end of the rotating plate 520 is hinged to the connecting plate 510. The transmission rod 540 is hinged so that the rotating plate 520 rotates counterclockwise around the end of the rotating plate 520 near the connecting plate 510. One end of the movable frame 410 is connected to the rotating plate 520 through the vertical rod 523, so that the rotating plate 520 can drive the movable frame 410 to rotate counterclockwise around the end of the rotating plate 520 near the connecting plate 510. In this way, the angle between the spray frame 300 and the movable frame 410 gradually decreases, thereby achieving the purpose of the water spray assembly 400 closing inward. Similarly, when the second cylinder 310 extends, the angle between the spray frame 300 and the movable frame 410 gradually increases, thereby achieving the purpose of the water spray assembly 400 expanding outward.

[0033] A spring 550 is provided between the bottom surface of the extension plate 522 and the movable frame 410. A limiting plate 521 is provided on the end face of the rotating plate 520 away from the connecting plate 510. A bolt 521a is installed on the limiting plate 521. When the movable frame 410 or the water spray pipe 420 is not subjected to external force, due to the force of the spring 550 between the movable frame 410 and the extension plate 522, one side of the movable frame 410 will abut against one end of the bolt 521a. At this time, an angle greater than 90° and less than 180° will be formed between the movable frame 410 and the rotating plate 520, so that the spring 550 can stably pull the movable frame 410. The movable frame 410 is designed to prevent it from easily rotating towards the rotating plate 520. When the movable frame 410 or the water spray pipe 420 touches an obstacle and the movable frame 410 rotates towards the rotating plate 520, the spring 550 will be stretched to allow the movable frame 410 to withstand a greater force. After the movable frame 410 and the water spray pipe 420 pass over the obstacle, the movable frame 410 will rotate away from the rotating plate 520 due to the elastic force of the spring 550, thus unfolding again. In this way, the function of avoiding obstacles can be achieved, and the water spray pipe 420 and the movable frame 410 can be better protected.

[0034] The spray frame 300 has a connecting frame 320 inside, and the connecting frame 320 has a connecting rod 330 for connecting the connecting plate 510. Both ends of the second cylinder 310 are hinged to hinge seats 311, and the bottom of each hinge seat 311 is movably connected to a hinge rod 311a. Specifically, the surface of the hinge rod 311a has an annular groove (not shown in the figure). The hinge rod 311a is movably locked to the bottom of the hinge seat 311 through the annular groove. The hinge rod 311a of one hinge seat 311 is connected to the second corner 532, and the hinge rod 311a of the other hinge seat 311 is connected to the connecting frame 320. Through the cooperation of the hinge seat 311 and the hinge rod 311a, the stress generated between the second cylinder 310 and the transmission angle plate 530 can be eliminated. At the same time, the stress generated between the second cylinder 310 and the connecting frame 320 can also be eliminated.

[0035] like Figure 1 and Figure 5As shown, the mounting assembly 100 includes a mounting plate 110. The two sides of the lifting plate 200 are hinged to the mounting plate 110 via at least two hinge blocks 120. A first cylinder 130 is hinged to the mounting plate 110. The end of the first cylinder 130 away from the mounting plate 110 is hinged to the lifting plate 200. In normal use, the first cylinder 130 needs to be extended so that the lifting plate 200 is at its lowest position. When the lifting plate 200 needs to be raised, the first cylinder 130 is simply retracted. At this time, the first cylinder 130 will pull the lifting plate 200 upward relative to the mounting plate 110. Specifically, because one end of each hinge block 120 is hinged to the mounting plate 110... 10. The other end of the hinge block 120 is hinged to the lifting plate 200, while the mounting plate 110 remains stationary. Thus, the hinge block 120 and the lifting plate 200 will flip upward around the end of the hinge block 120 near the mounting plate 110, thereby raising the lifting plate 200 and the spray frame 300. When the first cylinder 130 is fully retracted, the lifting plate 200 rises to the highest position of its travel stroke. At this time, the lifting plate 200 and the spray frame 300 are higher than the chassis height of the cleaning truck, and the first cylinder 130 stops working. Conversely, when the first cylinder 130 is fully extended, the lifting plate 200 descends to the lowest position of its travel stroke, and the first cylinder 130 stops working.

[0036] The mounting plate 110 is provided with at least two hook plates 140, and each hook plate 140 has a hook part 141 at its top. During installation, the hook part 141 on the hook plate 140 is hooked onto the front of the cleaning vehicle to complete the connection between the cleaning device and the cleaning vehicle.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
