Description

Technical Field

[0001] This utility model relates to a vacuum cleaner truck, specifically a vacuum cleaner truck with an anti-splash device. Background Technology

[0002] Currently used vacuum trucks typically travel at high speeds when operating on highways or urban expressways. During the journey, the sweeping discs located on the side of the chassis sweep foreign objects from the outside of the vehicle to the bottom of the vehicle and then suck them into the vehicle through the suction cups to improve cleaning efficiency.

[0003] However, this working mode can cause a series of problems: due to the high speed of the vacuum truck, the suction cups at the bottom are limited by the suction range and airflow distribution, and some lighter or larger foreign objects cannot be effectively sucked in. Instead, they are easily thrown out from the bottom of the vacuum truck by the high-speed airflow, causing the suction cups to be unable to pick up these foreign objects, which in turn affects the cleanliness of other parts of the road. In addition, the kinetic energy generated by the high-speed rotation of the sweeping disc will cause foreign objects to splash at too high a speed, which can easily damage the vacuum truck's own sensors, lights and other precision parts. In some cases, it may even break through the windshields of surrounding vehicles, seriously threatening the safety of the vacuum truck itself and surrounding vehicles. Utility Model Content

[0004] The main purpose of this utility model is to solve the problem that the high speed of existing vacuum cleaners during operation may cause some foreign objects to splash, threatening the safety of the vacuum cleaner itself and surrounding vehicles, and to provide a vacuum cleaner with an anti-splash device.

[0014] Furthermore, the swing cylinder is equipped with a self-locking structure to lock the rotation position of the swing cylinder after adjustment, so as to fix the suspended position of the anti-splash plate and prevent it from becoming loose due to the bumps generated when the vacuum cleaner is working; the rotation angle of the swing cylinder is in the range of 90°-360°, and its rotation angle needs to be preset according to the height of the vacuum cleaner chassis and the usage requirements before operation.

[0015] Furthermore, the portion of the chain located between the driven sprocket and the splash guard extends perpendicularly to the upper edge of the splash guard; the adjustment height of the splash guard is equal to the arc length of the corresponding rotation angle on the pitch circle of the driving sprocket.

[0016] Furthermore, the two driven sprockets are mounted at the same height on the vehicle body beam via sprocket mounting brackets.

[0017] Furthermore, the upper edge of the splash guard is provided with a chain mounting seat, and the other end of each chain is set in the chain mounting seat and fixed by a fixing pin.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] A vacuum cleaner truck with a splash-proof device includes a vehicle body and a main beam mounted on the vehicle body; characterized in that it further includes a splash-proof device mounted on the main beam of the vehicle body; wherein the overall structure of the splash-proof device is as follows: Figure 1 As shown, it includes a swing cylinder 2, a main shaft 1, and two sets of sprocket and chain drive assemblies; the swing cylinder 2 is fixed on a beam located on one side of the vehicle body, one end of the main shaft 1 is mounted on a beam located on the other side of the vehicle body through a main shaft fixing seat 3, and the other end is fixedly connected to the output end of the swing cylinder 2;

[0032] The swing cylinder 2 is driven by a hydraulic system installed inside the vehicle body. Specifically, the swing cylinder 2 is equipped with a swing motor, the output end of the external hydraulic system is connected to the swing motor, and the output end of the swing motor is fixedly connected to the main shaft 1. The external hydraulic system is used to drive the swing motor to rotate, so as to drive the main shaft 1 to rotate.

[0033] Each sprocket and chain drive assembly includes a driving sprocket 4, two driven sprockets 6, two chains 5, and a splash guard 8. The two driving sprockets 4 are coaxially fixed to the main shaft 1 and are located on the inner side of two main beams on the vehicle body. Specifically, each driving sprocket 4 consists of two sprockets fixedly connected side by side. The two driven sprockets 6 in each sprocket and chain drive assembly are respectively located on the front and rear sides of the driving sprocket 4 and are installed on the inner side of the main beam on one side of the vehicle body through sprocket mounting seats 7.

[0034] In each sprocket and chain drive assembly, one end of the front chain 5 is fixedly connected to and meshes with one sprocket of the driving sprocket 4, while its middle portion meshes with the driven sprocket 6 located at the front, and the other end is fixed to the front of the splash guard 8. One end of the rear chain 5 is fixedly connected to the other sprocket of the driving sprocket 4 and meshes with it, while its middle portion meshes with the driven sprocket 6 located at the rear, and the other end is fixed to the rear of the splash guard 8. The portion of each chain 5 located between the driven sprocket 6 and the splash guard 8 extends perpendicularly to the upper edge of the splash guard 8. At this time, the adjustment height of the splash guard 8 is equal to the arc length of the corresponding rotation angle on the pitch circle of the driving sprocket 4.

[0035] Each sprocket mounting base 7 is provided with a chain guard, which is located on the outside of the corresponding chain 5 to prevent the chain 5 from falling off the corresponding driven sprocket 6;

[0036] Both splash guards 8 are located inside the sweeping disc at the bottom of the vacuum truck and can move vertically up and down under the drive of the chain 5; each splash guard 8 has a double-layer structure to prevent it from being punctured by flying debris; specifically, the upper edge of the splash guard 8 is provided with a chain mounting seat 9, such as... Figure 2 As shown, the other end of each chain 5 is set in the chain mounting base 9 and fixed by the fixing pin 10.

[0037] The rotation angle range of the swing cylinder 2 is 90°-360°. Before operation, its rotation angle needs to be preset according to the height of the vacuum truck chassis and the usage requirements. Before the vacuum truck starts working, the lower edge of the anti-splash plate 8 contacts the ground. In this embodiment, the rotation angle of the swing cylinder 2 is set to 90°, and the adjustment height of the anti-splash plate 8 is 300mm.

[0038] The swing cylinder 2 is equipped with a self-locking structure. After the swing cylinder 2 drives the main shaft 1 and the drive sprocket 4 mounted on it to rotate 90°, the self-locking structure locks the swing cylinder 2, thereby fixing the suspended position of the anti-splash plate 8 and preventing it from becoming loose due to the bumps generated when the vacuum cleaner is working.

[0039] The specific working process of this embodiment is as follows:

[0040] Before the vacuum cleaner starts working, the lower edge of the anti-splash plate 8 contacts the ground. The rotation angle of the swing cylinder 2 is set according to the chassis height of the vacuum cleaner and the usage requirements. In this embodiment, the rotation angle of the swing cylinder 2 is set to 90°.

[0041] After the vacuum truck starts working, the external hydraulic system drives the swing cylinder 2, which drives the main shaft 1 and the drive sprocket 4 set on it to rotate. The drive sprocket 4 pulls the chain 5 fixedly connected to it to lift the splash guard 8 and adjust the splash guard 8 so that the distance between its lower edge and the ground is 300mm.

[0042] When the rotation angle of the swing cylinder 2 reaches 90°, the swing cylinder 2 is locked by its internal self-locking structure, fixing the height of the lower edge of the anti-splash plate 8 at 300mm above the ground. At this time, the vacuum cleaner can carry out normal cleaning and vacuuming operations. The anti-splash plate 8 can prevent some foreign objects from splashing out of the bottom of the vacuum cleaner during the cleaning process. The splashed foreign objects are blocked by the anti-splash plate 8 and fall vertically back to the bottom of the vacuum cleaner, which is beneficial to the cleaning operation of the vacuum cleaner and the safety of surrounding vehicles.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. For those skilled in the art, modifications can be made to the specific technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. However, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions protected by this utility model.
