Description

Technical Field

[0001] This utility model relates to the technical field of sanitation vehicle cleaning structure, specifically to a cleaning structure for sanitation vehicles. Background Technology

[0002] In sanitation operations, the sweeping structure of a sanitation vehicle is a key component for achieving efficient cleaning. After a period of use, the sweeping discs of this structure wear down, requiring regular replacement to maintain cleaning effectiveness. Traditionally, sweeping discs are mostly connected to the load-bearing components using bolts. When this connection method requires replacement of the worn-out sweeping disc, operators must use wrenches and other tools to disassemble each bolt individually, which is not only cumbersome but also time-consuming. To solve these problems, this utility model provides a sweeping structure for sanitation vehicles. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a cleaning structure for sanitation vehicles. By setting up inserts, slots and locking blocks, the cleaning disc can be easily disassembled and installed, which greatly shortens the replacement time of the cleaning disc and improves the maintenance efficiency of sanitation vehicles.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a cleaning structure for sanitation vehicles, comprising:

[0005] A base rod, which is connected to the frame of the sanitation vehicle;

[0006] The support assembly is slidably mounted on the base rod and its lifting and lowering are controlled by an electric push rod mounted on the base rod. The two ends of the support assembly are equipped with quick-release parts for connecting the sweeping disc.

[0007] The cleaning disc is movably engaged with the quick-release part and controlled by a ring body installed on the quick-release part.

[0008] Preferably, the carrier component includes:

[0009] The lifting rod has through holes at both ends, and the middle part of the lifting rod is fixedly connected to the output rod of the electric push rod.

[0010] The mounting shaft has an upper end that passes through a through hole and folds outwards to form a flange, and a lower end that passes through a base rod and is connected to a quick-release part. The mounting shaft is connected to the sanitation department's drive equipment.

[0011] Preferably, the upper end face of the mounting shaft is provided with a groove, and a prism is slidably installed inside the groove, the prism being connected to an external driving device.

[0012] Preferably, a bearing is provided between the flange of the mounting shaft and the lifting rod.

[0013] Preferably, the quick-release part includes:

[0014] The fixed plate has multiple inserts fixedly installed on its lower side. The cleaning plate has an insertion port that matches the inserts. Both sides of the lower end of the inserts have locking blocks that can be movably engaged with the cleaning plate.

[0015] Preferably, the two locking blocks extend into a cavity inside the insert block at opposite ends and are connected to each other by a clamping unit, which has a clamping force that clamps the two locking blocks together in opposite directions.

[0016] Preferably, the end of the card block located inside the cavity is folded upward to form a limiting plate.

[0017] Preferably, the lower side of the end of the card block located outside the cavity is set as an inclined surface with the outside higher than the inside, and a ball bearing is rotatably installed on the upper side of the end of the card block located outside the cavity.

[0018] Preferably, the clamping unit includes:

[0019] An arc-shaped spring plate, the opening of which faces upward, and its two ends are fixedly connected to two locking blocks respectively.

[0020] Preferably, a top rod is provided above the arc-shaped spring plate, and the upper end of the top rod passes through the fixing plate and is fixedly connected to the ring body.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model, through the design of inserts, slots, and locking blocks, enables the downward pressure of the ring body to drive the top rod to press down the arc-shaped spring plate, causing the locking block to retract into the cavity, thereby quickly releasing the lock on the sweeping disc. At the same time, the lower side of the outer end of the locking block is designed as a guide slope with the outer side higher than the inner side. During installation, the sweeping disc only needs to be pushed upward, and the locking block will automatically reset and lock after being squeezed and retracted, greatly shortening the replacement time of the sweeping disc and improving the maintenance efficiency of sanitation vehicles.

[0023] This utility model uses an electric push rod to control the lifting of the load-bearing component. It can dynamically adjust the working height of the sweeping disc according to the thickness of the dust on the road surface and the condition of potholes: when sweeping thick dust, the sweeping disc is lowered to enhance the scraping force, and when passing through low-lying roads, the sweeping disc is raised to avoid rigid collisions, ensuring that the sweeping disc maintains an appropriate distance from the ground, effectively improving the sweeping effect and environmental adaptability.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a cleaning structure for sanitation vehicles, such as... Figures 1 to 6 As shown.

[0035] Example 1:

[0036] A cleaning structure for a sanitation vehicle includes a base rod 1, which serves as a basic support component. One end of the base rod 1 is bolted to the frame of the sanitation vehicle, providing a stable installation foundation for the entire cleaning structure.

[0037] A load-bearing assembly is slidably mounted on the base rod 1. The load-bearing assembly includes a lifting rod 5, which is a long, rod-shaped structure. Two mounting shafts 6 are rotatably mounted through symmetrical through holes at both ends. The middle part of the lifting rod 5 is fixedly connected to the output rod of the electric push rod 2. The upper end of the mounting shaft 6 passes through the through hole of the lifting rod 5 and then folds outward to form a flange. The diameter of the flange is larger than the diameter of the through hole of the lifting rod 5, which serves as a limit. A bearing is installed between the flange and the lifting rod 5. This bearing reduces the friction between the mounting shaft 6 and the lifting rod 5, reduces component wear, and makes power transmission smoother. The lower end of the mounting shaft 6 is movably engaged with a cleaning disc 3 via a quick-release mechanism.

[0038] The height of the lifting rod 5 can be controlled by extending or retracting the output rod of the electric push rod 2, thereby flexibly adjusting the height of the sweeping disc 3 according to the actual situation to adapt to different working conditions.

[0039] The upper end face of the mounting shaft 6 is provided with a groove 7, and a prism 17 is slidably installed inside the groove 7. The prism 17 is connected to the drive equipment on the sanitation vehicle. The cooperation between the groove 7 and the prism 17 enables the mounting shaft 6 to rotate stably while adjusting the height of the sweeping disc 3, thereby stably driving the sweeping disc 3 to rotate.

[0040] Example 2:

[0041] This embodiment focuses on describing the mechanical linkage design for quick disassembly of the quick-release part. The quick-release part includes a fixing plate 8, which is a circular disc structure. Multiple inserts 9 are evenly distributed and welded on its lower side. Multiple slots 10 are provided on the cleaning disc 3 corresponding to the positions of the inserts 9. The shape and size of the slots 10 are precisely matched with the inserts 9 to form a clearance fit.

[0042] Two locking blocks 11 are respectively provided on the two sides of the lower end of the insert block 9. One end of the locking block 11 extends into the rectangular cavity 12 inside the insert block 9 and folds upward to form a limiting plate 13. Inside the cavity 12, the two locking blocks 11 are connected by an arc-shaped spring plate 14. The arc-shaped spring plate 14 is made of high-strength spring steel and its opening faces upward. The setting of the limiting plate 13 can prevent the locking blocks 11 from sliding out of the cavity 12. At the same time, it can ensure that under the elastic force of the arc-shaped spring plate 14, the two locking blocks 11 stably extend out of the insert block 9, so that they can support the cleaning disc 3 from the lower side of the cleaning disc 3, so that the cleaning disc 3 and the fixed disc 8 are stably connected together.

[0043] A top rod 15 is provided above the arc-shaped spring plate 14. The top rod 15 is a cylindrical rod. Its lower end contacts the middle position of the arc-shaped spring plate 14, and its upper end passes through the fixed plate 8 and is fixed to the lower surface of the ring 4 located above the fixed plate 8.

[0044] During disassembly, the operator presses down on the ring 4, causing the push rod 15 to move down. The push rod 15 pushes the arc-shaped spring plate 14 to deform, causing the two locking blocks 11 to move towards each other. The locking blocks 11 disengage from the cleaning disc 3, and the cleaning disc 3 can be easily removed at this time.

[0045] A ball bearing 16 is rotatably mounted on the upper side of the locking block 11 located on the insertion block 9. The setting of the ball bearing 16 reduces the friction between the cleaning disc 3 and the locking block 11, making the movement of the locking block 11 more stable. When the push rod 15 pushes the arc-shaped spring plate 14, the two locking blocks 11 can move towards each other more stably.

[0046] Example 3:

[0047] To facilitate quick installation of the cleaning disc 3, the lower side of the end of the locking block 11 located outside the cavity 12 is designed as an inclined surface with the outside higher than the inside. The two locking blocks 11 facing each other are the inner ends. Simply align the insertion port 10 of the cleaning disc 3 with the insertion block 9 and push it upward. The edge of the cleaning disc 3 presses against the inclined surface of the locking block 11, causing the locking block 11 to retract into the cavity 12. When the cleaning disc 3 is installed in place, under the elastic force of the arc-shaped spring plate 14, the locking block 11 pops out and engages with the cleaning disc 3, completing the quick installation and greatly improving maintenance efficiency.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
