Description

Technical Field

[0001] The present invention relates to the technical field of highway cleaning, and more particularly to a highway cleaning device for highway engineering and a road surface cleaning method thereof. Background Art

[0002] Garbage and stains on the road can cause damage to road facilities such as corrosion and wear. Highway cleaning can not only remove these garbage and stains, but also reduce dust and reduce pollution to the environment.

[0003] The current road cleaning device is mainly composed of a high-pressure water spray device and a negative pressure recovery device. The high-pressure water spray device has a disc-shaped cover with an opening facing downward, and a crossbar that can rotate and spray water is installed inside. When cleaning the road, the opening of the cover is close to the road surface, and the crossbar rotates and sprays high-pressure water to clean the road surface. A circle of wear-resistant rubber is installed at the bottom of the cover to prevent water from escaping, and then the negative pressure recovery device recovers the cleaning water and dust impurities together. Since the water of this road cleaning device is sprayed downward quickly, it can flush out the dust in the gaps of the asphalt road surface, and the cleaning effect is better.

[0004] The right-angle corners of highway curbs are places where dust is more likely to accumulate. For example, a road water sprayer sprays water on both sides with its nozzle. The sprayed water concentrates all the dust on the road surface to the position of the highway curb without any subsequent treatment.

[0005] However, since the above-mentioned highway cleaning device is disc-shaped, even if the disc is close to the road curb, the water is confined to the disc for spraying. Therefore, the dust at the right-angle corners of the highway curb cannot be sprayed, cleaned and recovered, which has limitations. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Refer to the instruction manual Figure 1-Figure 9 A road cleaning device for road engineering includes a cleaning vehicle 1, a control arm 2 is installed on the cleaning vehicle 1, a disc 3 is installed at the front end of the control arm 2, a cleaning component 4 is arranged on the disc 3, the cleaning component 4 includes a water spray pipe 41 arranged at the bottom of the disc 3, a plurality of water spray holes 411 are arranged at the bottom of the water spray pipe 41, the water spray holes 411 are used to spray water downward to clean the road surface, a negative pressure chamber 31 is arranged at one side of the bottom of the disc 3, a connecting port 32 is arranged at one side of the negative pressure chamber 31, and the connecting port 32 is connected to the negative pressure device;

[0033] In the above technical solution, if Figure 6 As shown, the cleaning assembly 4 also includes a hollow shaft 40, which is vertically rotatably connected to the middle of the disc 3, and a motor 44 is fixedly installed above the disc 3. The output end of the motor 44 is fixedly connected to the upper end of the hollow shaft 40, and a water spray pipe 41 is fixedly installed at the lower end of the hollow shaft 40 and is connected to the interior of the hollow shaft 40, and water enters the interior of the water spray pipe 41 from the hollow shaft 40.

[0034] Furthermore, a water outlet sleeve 43 is sleeved on the upper end of the hollow shaft 40, and the water outlet sleeve 43 is fixedly connected to the disc 3. A water outlet 431 is provided on one side of the water outlet sleeve 43, and a water outlet hole 402 is provided on the side wall of the hollow shaft 40. The hollow shaft 40 is connected to the interior of the water outlet sleeve 43 through the water outlet hole 402, and the water outlet 431 is connected to the clean water tank 11 on the cleaning vehicle 1 through a water pump.

[0035] It should be noted that when cleaning the road, the water pump draws the water in the clean water tank 11 from the water outlet 431 into the water outlet sleeve 43, and the water then enters the hollow shaft 40 and the water spray pipe 41 from the water outlet hole 402, and finally sprays out from the water spray hole 411. During this process, the motor 44 drives the hollow shaft 40 and the water spray pipe 41 to rotate. The sprayed water can clean the dirt and dust on the road surface, even the dust in the gaps of the asphalt road surface can be removed.

[0036] In the above technical solution, the negative pressure device adopts a negative pressure fan, which is installed on the cleaning vehicle 1. Its input port is connected to the connecting port 32 through a hose, and its output port is connected to the waste water tank 12 on the cleaning vehicle 1. In the process of cleaning the road, the negative pressure fan draws water mixed with dust and mud into the waste water tank 12 to avoid dust and mud remaining on the road surface.

[0037] In this embodiment, if Figure 2-Figure 6 As shown, a fixed surrounding soft plate 6 is fixedly arranged around the outer side of the bottom of the disc 3, an open area is formed between the two ends of the fixed surrounding soft plate 6, two movable surrounding soft plates 61 are arranged at the position of the open area, one end of the two movable surrounding soft plates 61 is respectively fixedly connected to the two ends of the fixed surrounding soft plate 6, and the other end is a free end, and control components 7 are arranged on both sides of the upper surface of the disc 3, and the control component 7 includes an outward expansion rod 71, one end of the outward expansion rod 71 is hinged to the upper surface of the disc 3, and the other end of the outward expansion rod 71 is installed with a walking wheel 70, and the middle part of one side of the outward expansion rod 71 is fixedly connected with a driving rod 72, and the driving rod 72 is fixedly connected to the middle part of the one side of the outward expansion rod 71. One end of the rod 72 away from the outward expansion rod 71 is fixedly connected to the insertion rod 73, and the insertion rod 73 is fixedly connected to the free end of the dynamic surrounding soft plate 61. An elastic component 74 is connected between the outward expansion rods 71 ​​of the two control components 7, and the elastic component 74 is used to make the two outward expansion rods 71 ​​swing in a direction close to each other; when the corner 300 is not cleaned, the two dynamic surrounding soft plates 61 close the open area. When the corner 300 is cleaned, the two walking wheels 70 squeeze the side walls of the curb 200, so that the two walking wheels 70 move away from each other, so that the driving rod 72 drives the dynamic surrounding soft plate 61 to open the open area.

[0038] It should be noted that when the two movable surrounding soft plates 61 close the open area, the angle between the two outer expansion rods 71 ​​is greater than 25 degrees, and the purpose is that when the two running wheels 70 squeeze the side walls of the curb 200, the two outer expansion rods 71 ​​can move to both sides and open. In the above technical solution, the elastic component 74 is a spring, and the fixed surrounding soft plate 6 and the movable surrounding soft plate 61 are both made of wear-resistant rubber. The purpose of using wear-resistant rubber is that when cleaning, the fixed surrounding soft plate 6 and the movable surrounding soft plate 61 can be attached to the road surface to prevent water from flowing away from the bottom without being sucked away by the negative pressure fan.

[0039] In this embodiment, if Figure 4-Figure 6 As shown, a fixed spray assembly 5 is provided at a position in the open area inside the control arm 2 , and the fixed spray assembly 5 is used to spray water toward a corner 300 formed by a road 100 and a curb 200 .

[0040] In this embodiment, the implementation method is specifically as follows: when cleaning the corner 300 formed by the road 100 and the curb 200, first, the cleaning vehicle 1 is driven onto the road 100 and close to the corner 300 to be cleaned. Then, the control arm 2 drives the disc 3 to approach the curb 200, and under the action of the control arm 2, the running wheels 70 on the two expansion rods 71 ​​squeeze the side walls of the curb 200, so that the two expansion rods 71 ​​are opened to both sides, and the two expansion rods 71 ​​drive the two movable soft plates 61 to swing to both sides through the driving rod 72 to open the open area. Secondly, while driving the cleaning vehicle 1, the corner 300 is cleaned. During cleaning, the water pump draws the water in the clean water tank 11 from the water outlet 2 431, the water outlet 2 402, and the hollow shaft 40 into the water spray pipe 1 41 in sequence, and then sprays it downward from the water spray hole 1 411. At this time, the road surface is cleaned. After the water enters the hollow shaft 40, it also enters the fixed spray assembly 5, and is sprayed toward the corner 300 through the fixed spray assembly 5, thereby cleaning the corner 300. The sewage generated during the cleaning process is pumped into the waste water tank 12 from the position of the negative pressure chamber 31 by the negative pressure fan. When the corner 300 is not cleaned but only the road surface is cleaned, the two movable surrounding soft plates 61 are not opened, and the cleaning can be done directly.

[0041] The above technical solution is provided with a control component 7. When it is necessary to clean the corner 300, the method of 70 is used to press the curb 200 so that the two outward expansion rods 71 ​​drive the two movable surrounding soft plates 61 to open the open area, so that water can be flushed to the corner 300, and when opened, the free end of the movable surrounding soft plate 61 is attached to the side wall of the curb 200. The sewage will not flow to the outside, but will flow along the movable surrounding soft plate 61 and the fixed surrounding soft plate 6 to the bottom of the negative pressure chamber 31, and then be collected. Therefore, the device has the function of cleaning the normal road surface and the corner 300 at the same time, and even when cleaning the corner 300, the normal collection of sewage can be guaranteed.

[0042] Refer to the instruction manual Figure 2-Figure 6A water outlet sleeve 42 is sleeved on the hollow shaft 40, and the water outlet sleeve 42 is fixedly connected to the top wall of the bottom of the disc 3. A water outlet port 421 is opened on one side of the water outlet sleeve 42, and a water outlet hole 401 is opened on the side wall of the hollow shaft 40. The hollow shaft 40 is connected to the interior of the water outlet sleeve 42 through the water outlet hole 401, and the fixed spray assembly 5 is connected to the water outlet port 421.

[0043] It should be noted that the water entering the hollow shaft 40 can enter the water outlet sleeve 42 from the water outlet hole 401, and then enter the fixed spray assembly 5 from the water outlet 421.

[0044] In this embodiment, since the open area is always facing the curb 200 and the corner 300 when cleaning the corner 300, if the fixed spray assembly 5 is rotated along with the hollow shaft 40 and the water spray pipe 41, the corner 300 can certainly be cleaned. However, during the rotation process, the fixed spray assembly 5 sprays toward the fixed surrounding soft board 6 and the dynamic surrounding soft board 61 for a long time, and this part of the water is not utilized, resulting in waste, and the water sprayed to the corner 300 is also intermittent, the flushing time is short, and the cleaning is not thorough. Therefore, an improved structure of the fixed spray assembly 5 is proposed.

[0045] Specifically, the fixed spray assembly 5 includes a hard pipe 51, which is fixedly connected to the water outlet 421. The disc 3 is located at the bottom of the open area and is fixedly connected to a water spray pipe 52. The hard pipe 51 and the water spray pipe 52 are connected through a hollow soft sleeve 53. The water spray pipe 52 is provided with a plurality of water spray holes 521 on one side facing the open area.

[0046] Furthermore, pressure rods 8 are provided on both sides of the hollow soft sleeve 53, one end of the pressure rod 8 is fixedly connected to one end of the outward expansion rod 71 close to the disc 3, and the rotation axis of the pressure rod 8 coincides with the rotation axis of the outward expansion rod 71. When the two outward expansion rods 71 ​​approach each other, the two pressure rods 8 clamp the two sides of the hollow soft sleeve 53 to isolate the water on both sides of the hollow soft sleeve 53.

[0047] It should be noted that if Figure 5 As shown, when the two outward expansion rods 71 ​​open the two movable surrounding soft panels 61, the two pressure rods 8 are away from the hollow soft sleeve 53. When the corner 300 is cleaned, the two outward expansion rods 71 ​​approach each other under the action of the elastic component 74, so that the two fixed surrounding soft panels 6 are closed, and the two pressure rods 8 swing together with the two outward expansion rods 71. Finally, the two pressure rods 8 are respectively pressed on the sides of the two hollow soft sleeves 53, so that the hollow soft sleeves 53 are deformed to isolate the water, thereby preventing the water from spraying out from the second water spray hole 521.

[0048] Refer to the instruction manual Figure 2-Figure 6After the two movable surrounding soft plates 61 are opened, an opening will appear at the upper position between the two movable surrounding soft plates 61. When water is sprayed, it may splash out from the top to the outside and easily wet pedestrians. Therefore, it should be closed.

[0049] Specifically, a through hole 33 is opened on the side wall of the disc 3 located in the open area, and a waterproof cloth 9 passes through the through hole 33. The side of the waterproof cloth 9 close to the dynamic surrounding soft plate 61 is fixedly connected to the dynamic surrounding soft plate 61, and the side of the fixed surrounding soft plate 6 close to the middle of the disc 3 is fixedly connected to the pressure rod 8 through a plurality of pull ropes 91.

[0050] It should be noted that when the two movable surrounding soft panels 61 are opened, the two pressure rods 8 also swing to one side of the open area, so that the movable surrounding soft panels 61 can pull the waterproof cloth 9 outward from the through opening 33, and the openings above the two movable surrounding soft panels 61 are blocked through the waterproof cloth 9 to prevent water from splashing out and affecting pedestrians. When the two movable surrounding soft panels 61 close the open area, the pressure rod 8 can pull the waterproof cloth 9 through 91, so that the waterproof cloth 9 is retracted from 33 to the inside of 3. The purpose of using the pressure rod 8 to pull the waterproof cloth 9 is to prevent the waterproof cloth 9 from being unable to pass through the through opening 33 by itself when no pulling force is applied, but folding between the fixed surrounding soft panel 6 and the side wall of the disc 3, which may easily cause the two movable surrounding soft panels 61 to be incompletely closed, leaving gaps, and water can easily flow out from there.

[0051] Refer to the instruction manual Figure 2-Figure 3 The control arm 2 includes a fixed plate 21 fixedly mounted on the cleaning vehicle 1, the front side of the fixed plate 21 is rotatably connected to a swing arm 22, the front end of the swing arm 22 is rotatably connected to a swing arm 23, a cylinder 24 is provided on the fixed plate 21, the two ends of the cylinder 24 are respectively hinged to the fixed plate 21 and the swing arm 22, a motor 25 is installed on the swing arm 22, the motor 25 is used to drive the swing arm 23 to rotate, and the disc 3 is installed at the front end of the swing arm 23.

[0052] Furthermore, the swing arm 23 is sequentially installed with a cylinder 27, a rocker 26 and a cylinder 3 28 from bottom to top, and the two ends of the rocker 26 and the cylinder 3 28 are respectively hinged to the swing arm 23 and the disc 3, and the two ends of the cylinder 2 27 are respectively hinged to the swing arm 23 and the rocker 26.

[0053] It should be noted that cylinder 1 24 can drive swing arm 1 22 to swing, and motor 1 25 can drive swing arm 2 23 to swing. The cooperation between the two can adjust the position of disc 3. The telescopic cooperation between cylinder 2 27 and cylinder 3 28 can also adjust the position of disc 3, such as making disc 3 face directly downward, or making disc 3 swing upward to expose the bottom of disc 3 for easy maintenance.

[0054] Refer to the instruction manual Fig. 9This embodiment also provides a road cleaning method, using the above-mentioned road cleaning device for highway engineering, comprising the following steps:

[0055] Step 1: driving the cleaning vehicle 1 onto the road 100 and approaching the corner 300 to be cleaned;

[0056] Step 2: The control arm 2 drives the disc 3 to approach the curb 200, so that the running wheels 70 on the two outward expansion rods 71 ​​squeeze the curb 200, so that the two outward expansion rods 71 ​​open to both sides, and the two driving rods 72 drive the dynamic surrounding soft plate 61 to open the open area;

[0057] Step 3: The water spray hole 411 sprays water downward to clean the road 100, and the fixed spray component 5 sprays water to clean the curb 200. During this process, the negative pressure device at the position of the negative pressure chamber 31 draws the cleaned water and debris from the connecting port 32 into the waste water tank 12 on the cleaning vehicle 1.

[0058] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
