Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a municipal road maintenance device. Background Technology

[0002] During the maintenance of municipal roads, it is necessary to sweep the road surface. There are two ways to sweep: one is manual sweeping, and the other is to use sweeping equipment to sweep the road surface. Since manual sweeping is slower, sweeping equipment is mostly used.

[0003] Existing road sweeping devices are inconvenient to adaptively adjust the cleaning height when sweeping uneven roads. If the road surface is uneven, it will be difficult to clean the road thoroughly, thus affecting the cleaning effect. Some devices with adjustment functions require manual observation and adjustment, which is inconvenient to operate. If the adjustment is too high, some areas will not be cleaned, and if it is too low, it will damage the brushes. For example, when the brushes pass over speed bumps or similar raised areas on the ground, the shorter brushes on push sweepers will bend excessively, causing the cleaning to shift from the bottom of the brush to the base, which greatly increases the stress on the brush base and can easily lead to brush breakage or detachment, which is not conducive to its long-term use.

[0004] A municipal road maintenance device is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a municipal road maintenance device to solve the problem mentioned in the background art: during the sweeping process, when the brush passes over speed bumps or similar raised areas on the ground, the shorter brushes on the push sweeper will bend excessively, causing the normal sweeping from the bottom of the brush to the root of the brush, which seriously increases the stress on the root of the brush, making it easy for the brush to break or fall off, which is not conducive to its long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal road maintenance equipment, including a sweeping cart, the sweeping cart including a cart platform, and a dust collection structure installed on the top surface of the cart platform;

[0023] 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.

[0024] Please see Figure 1 - Figure 5 The present invention provides a technical solution: a municipal road maintenance equipment, including a sweeping cart 1, the sweeping cart 1 including a cart 101, and a dust suction structure 102 installed on the top surface of the cart 101;

[0025] A cleaning assembly 2 is provided on one side of the vehicle platform 101. The cleaning assembly 2 includes a mounting shell 201 fixed to one side of the vehicle platform 101. A top cover 202 covers the top surface of the mounting shell 201. A drive shaft 203 is rotatably connected to one side of the interior of the mounting shell 201. Several first bevel gears 204 are fixedly connected to the outside of the drive shaft 203. A vertical plate 205 is fixedly connected to the lower interior of the mounting shell 201. A connecting shaft 206 is rotatably connected to the top of the vertical plate 205. Second bevel gears 207 and third bevel gears 208 are respectively installed at both ends of the connecting shaft 206. Several fourth bevel gears 209 are provided on the lower interior of the other side of the mounting shell 201. A support sleeve 210 is rotatably connected to the bottom surface of the fourth bevel gears 209. A drive shaft 211 is slidably connected to the middle of the fourth bevel gears 209. The drive shaft 211 passes through... The bottom of the mounting housing 201 is fixedly connected to the mounting plate 212, the bottom of the mounting plate 212 is fixedly connected to the brush 213, the middle of the bottom surface of the mounting plate 212 is fixedly connected to the tapered column 214, and the bottom end of the tapered column 214 is rotatably connected to the bottom ball 215. A four-stage bevel gear transmission structure (204-207-208-209) is adopted to achieve 90° power steering and amplify torque, which is particularly suitable for driving high-load actuators such as rotating brush 213. The tapered column 214 and the bottom ball 215 form an adaptive floating mechanism. When encountering an obstacle, the bottom ball 215 rolls to lift the mounting plate 212 as a whole. Compared with traditional fixed brushes, abnormal wear can be reduced. The bottom of the mounting housing 201 is provided with a clearance hole, which allows the drive shaft 211 to be perfectly inserted, making the interior of the mounting housing 201 almost sealed.

[0026] The bottom surface of the top cover 202 is fixedly connected with several threaded posts 216. The threaded posts 216 are fitted with threaded caps 217, springs 218 and pads 219 from top to bottom. The pads 219 are in contact with the top surface of the drive shaft 211. The threaded posts 216 are slidably inserted into the top of the drive shaft 211. The pressure adjustment mechanism achieves stepless pressure adjustment through thread self-locking. With the preload of the spring 218, the brush contact pressure can be adjusted according to different road surface characteristics (such as asphalt / cement).

[0027] A first motor 221 is fixedly connected to one end of the outer side of the mounting housing 201. The output end of the first motor 221 extends into the mounting housing 201 and is fixedly connected to the drive shaft 203. The first bevel gear 204 meshes with the second bevel gear 207. The enclosed gearbox design effectively prevents sand and gravel from entering and is suitable for long-term outdoor operation.

[0028] The support sleeve 210 is fixedly connected to the inner bottom surface of the mounting shell 201, and the third bevel gear 208 is meshed with the fourth bevel gear 209.

[0029] A vertical groove 220 is provided on the outer side of the drive shaft 211, and the vertical groove 220 is slidably connected to the middle part of the fourth bevel gear 209. The middle part of the fourth bevel gear 209 is provided with a dovetail hole. With the dovetail structure design of the vertical groove 220, the drive shaft 211 can withstand bidirectional axial force, and maintain the engagement state between the drive shaft 211 and the bevel gear 209 during the adaptive lifting process to avoid power interruption.

[0030] The top cover 202 is fixed to the top surface of the mounting shell 201 by several bolts; the modular top cover design supports quick maintenance.

[0031] The threaded cap 217 is threadedly connected to the threaded post 216. The top of the spring 218 is fixedly connected to the bottom surface of the threaded cap 217, and the bottom of the spring 218 is fixedly connected to the pad 219. The pad 219 is movably sleeved on the bottom of the threaded post 216. The bottom surface of the pad 219 is surface-treated with solid lubricant spray. It adopts a double-safety anti-loosening design (threaded locking + spring preload) to maintain stable pressure output under vibration environment. Combined with the solid lubricant coating of the pad 219, it reduces the friction coefficient of the contact surface.

[0032] Working principle: Before using this type of municipal road maintenance equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, the first motor 221 is first started, driving the drive shaft 203 to rotate the first bevel gear 204. Through the transmission structure connecting the shaft 206, the third bevel gear 208, and the second bevel gear 207, the fourth bevel gear 209 is rotated. The fourth bevel gear 209 is slidably connected to the drive shaft 211 through the vertical groove 220, driving the drive shaft 211 to rotate, which in turn drives the mounting plate 212 to rotate. The rotating brush 213 sweeps up the dust on the ground to form floating dust, which is easily extracted and stored by the vacuuming structure 102.

[0033] When the sweeping cart 1 passes over speed bumps or other raised areas, some of the brushes 213 bend immediately upon contact with the speed bump. As the bottom ball 215 rolls up the ramp of the speed bump, the conical column 214 pushes the mounting plate 212 upwards, reducing the bending amplitude of the brushes 213 caused by compression. After the brushes 213 have completely passed the speed bump, the bottom ball 215 rolls down the ramp, and the mounting plate 212 returns to its original position. This adaptive process requires no manual intervention, significantly reducing the bending degree of the brushes 213 throughout the process, reducing the risk of hair loss and breakage, and extending service life.

[0034] The pressure exerted on the ground by the brush 213 can be adjusted according to its length, weight, softness, and the amount of dust on the ground. If increased pressure is required, the top cover 202 needs to be removed, and the threaded cap 217 rotated to move it down and compress the spring 218. The spring 218 increases the pressure on the top surface of the drive shaft 211 through the pad 219, thereby indirectly enhancing the contact pressure of the brush 213 on the ground and preventing stubborn dust residue due to insufficient pressure. After removing the top cover 202, the internal gears can also be lubricated and maintained.

[0035] When the brush 213 is severely worn, flip the car plate 101 to the side to pull out the drive shaft 211 from the mounting housing 201 and the fourth bevel gear 209; align the new brush 213 with the clearance hole at the bottom of the mounting housing 201, slide it in along the middle of the fourth bevel gear 209, and after ensuring that the mounting plate 212 does not come out of the clearance hole, flip the car plate 101 to complete the quick replacement.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
