Description

Technical Field

[0001] This utility model relates to the field of ground cleaning technology, specifically a road sweeper washing structure. Background Technology

[0002] In urban road cleaning operations, road sweepers have become the main force in cleaning urban roads due to their efficient washing capabilities. However, when faced with the need to wash away silt from pedestrian walkways, large washing trucks, due to their large size, cannot get close enough to the pedestrian walkways to wash them effectively. As a result, the current work of washing silt from pedestrian walkways mainly relies on sanitation workers to use handheld washing hoses.

[0003] However, during the rinsing process, the high-pressure water flow output from the rinsing pipe will generate a strong reaction force. Sanitation workers need to hold the rinsing pipe with continuous force and control its direction. Prolonged operation can easily lead to arm fatigue for sanitation workers, and may even cause the rinsing pipe to slip out of their hands due to an unstable grip, posing a safety hazard and affecting the comfort and safety of the operation.

The hydraulic rod 6 is parallel to the ground, and the drive end of the hydraulic rod 6 is connected to the mounting support rod 7.

[0027] Furthermore, the connecting block 8 is located at one end of the mounting support rod 7 near the boom support rod 5. The connecting block 8 is fixedly installed on the surface of the mounting support rod 7, and the hydraulic rod 10 is rotatably installed inside the connecting block 8.

[0028] Furthermore, the rotating assembly includes a rotating block 11 located at the end of the forearm support rod 9 away from the mounting back plate 1. A universal bearing 12 is rotatably mounted between the rotating block 11 and the forearm support rod 9. A handheld component 13 is fixedly mounted on the side of the rotating block 11 close to the mounting back plate 1, and a fixing component 14 is fixedly mounted on the side of the rotating block 11 away from the mounting back plate 1 for fixing the flushing pipe.

[0029] Please see Figure 2 The present invention provides a technical solution: Further, the handheld component 13 is composed of three parts: a shelf 131, a support block 132, and a handheld rod 133. The shelf 131 is located on the side of the rotating block 11 near the mounting back plate 1. The support block 132 is fixedly installed at the bottom of the shelf 131 and is fixedly installed on the rotating block 11. The handheld rod 133 is fixedly installed inside the shelf 131. The shelf 131 in the handheld component 13 can be used for the hand of sanitation workers, and the hand holding the handheld rod 133 can drive the flushing pipe on the fixing component 14 to move along the direction of force.

[0030] Please refer to the figure. Figure 3 The present invention provides a technical solution: further, the fixing member 14 is composed of four parts: a first fastening ring 141, a second fastening ring 142, a through groove 143, and a buffer pad 144. The first fastening ring 141 is fixedly installed on the side of the rotating block 11 by a bracket. The second fastening ring 142 is threadedly installed on one side of the first fastening ring 141. A through groove 143 is opened on the surface of the first fastening ring 141 near the second fastening ring 142. The buffer pad 144 is fixedly installed inside the first fastening ring 141.

[0031] Furthermore, the inner cross-sections of both fastening ring 141 and fastening ring 142 are trapezoidal, and the buffer pad 144 is made of flexible material.

[0032] Working Principle: When using the road sweeper's flushing structure, the flushing pipe is first passed through the fixing piece 14 and secured to the flushing structure. Then, the mounting back plate 1 is fixed to the back of the sanitation worker via the shoulder strap 2 and waist belt 3. This design evenly distributes the weight of the equipment over a large area of ​​the shoulders, avoiding excessive localized stress that could cause marks and pain. Furthermore, the waist belt 3 fits snugly against the waist, transferring the overall weight of the equipment downwards to the hips, forming a coordinated support system with the shoulder strap 2. Together, these two components transfer most of the weight of the flushing structure from the arms and upper body to the core of the body, greatly reducing the burden on the worker when operating it by hand. This effectively reduces shoulder and arm fatigue during long work periods, ensuring both efficiency and comfort.

[0033] In addition, after controlling the water flow in the flushing pipe, the flushing amplitude between the water flow and the ground can be freely adjusted by hand using the handheld part 13. This facilitates the flushing pipe to flush the silt on the ground. The design of hydraulic rods 10 and 6 not only makes it suitable for different body lengths of sanitation workers and easy to operate, but also allows the flushing pipe to be adjusted to a certain angle with the ground during use. It can automatically form a force-saving lever effect according to the force and lever arm changes. When maintaining the flushing angle and force, only a small force is needed to overcome the water flow reaction force and the weight of the equipment itself to flush the silt on the ground. Compared with traditional hand-held flushing, it can effectively reduce the burden on the worker's arms and shoulders and reduce their overall labor intensity.

[0034] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
