Description

Road guardrail cleaning vehicle

technical field

The invention relates to the technical field of sanitation cleaning equipment, in particular to a road guardrail cleaning vehicle, which is mainly used for cleaning guardrails in streets, communities and some special environments.

Background technique

With the rapid development of society, the economy of cities and towns in our country has also developed rapidly, and the construction of highways, especially expressways, as the link connecting various towns, is an important indicator of a country's economic development. With the continuous improvement and development of the domestic road system and the continuous improvement of people's requirements for sanitation work, it has become an inevitable trend to vigorously promote the mechanization of road cleaning. In recent years, the increasing flow of people and vehicles has also brought a lot of trouble to the cleaning of the guardrails. It is easy to cause the increase of flying dust and domestic garbage in the process of travel and driving, which brings great harm to the development of urban sanitation work. More and more troubles have made it more and more difficult to clean up urban roads, especially the cleaning of road safety fences, which is difficult to complete by simply using manpower to clean.

As a road guardrail cleaning vehicle that liberates manpower, its appearance and application are inevitable. It is developed and designed for guardrails that are difficult to clean by manpower. It is mainly composed of cleaning system, power system, water storage and supply system and carrier. Vehicles and other major institutions. As one of the important equipment for urban road cleaning, it has been widely used in the cleaning of urban road guardrails, and used to replace the ordinary manual cleaning mode, improve the efficiency of sanitation and cleaning work, and reduce the waste of resources.

Cleaning the guardrail by manpower will inevitably face several unavoidable problems: first, the required amount of manpower and material resources is very large; second, the road is intricate and the actual road conditions are different in varying degrees, which increases the difficulty of cleaning; Third, the efficiency of manual cleaning is low. If manual cleaning is used in some major traffic sections, it will easily cause traffic jams and slow cleaning. Fourth, the tools used in the manual cleaning process are relatively simple and easy to cause waste of resources. The problems listed above are only part of the problems in the manual cleaning process. In order to effectively solve these problems, it is very necessary to promote the mechanization of guardrail cleaning.

As early as the early 1980s, Ford Motor Manufacturing Company of the United States developed a simple road guardrail cleaning vehicle. Although it is composed of simple mechanical brackets and roller brushes as a whole, the cleaning effect is not so ideal, but this is the guardrail cleaning vehicle from the beginning. The leap forward from nothing is the first step to liberate people from the complicated guardrail cleaning work. After the United States, Germany's Mudica company also launched their cleaning equipment. They effectively applied the hydraulic power system to the road guardrail cleaning vehicle, making the operation of the cleaning device smoother and more convenient. The guardrail cleaning vehicle produced by Henan Road Kewei Highway Machinery Co., Ltd. is not only more beautiful and tidy in the appearance design of the guardrail cleaning vehicle, but also adjusts the storage method of the cleaning device so that the cleaning device can be stored in the compartment so that The storage of the cleaning device becomes more convenient, which is beneficial to the overall maintenance and management of the cleaning vehicle. At the same time, the movement trajectory of the cleaning brush during the working process can be fine-tuned through the self-floating adjustment device to prevent the cleaning brush from Inadequate cleaning occurs.

At present, the guardrail cleaning vehicles that have been launched in China all have some similar characteristics: (1) The huge body needs to be equipped with small and medium-sized truck chassis, which is undoubtedly a major factor affecting the high production cost; (2) None or very few There are few sewage recovery and recycling devices, which leads to sewage directly remaining on the road near the guardrail, which is likely to cause secondary pollution when the traffic passes by, and because there is no sewage recycling device, there is a certain waste of water and it takes a long time to work. It is necessary to stop the operation for water replenishment; (3) The vehicle body is huge, and the necessary flexibility is lacking in the cleaning operation process. It cannot be effectively cleaned when facing some residential areas or working areas in the campus. When encountering some special road sections, such as: turning road sections It is also difficult to effectively clean the road sections with narrow lanes.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The invention specifically relates to a road guardrail cleaning vehicle, which is a small guardrail cleaning vehicle based on a tricycle and designed with reasonable measures. The present invention is proposed in order to solve the problems such as difficulty in cleaning guardrails by manpower, low efficiency, poor maneuverability of large-scale machinery, and the like.

Accompanying drawing 1-3 is the whole vehicle schematic diagram of guardrail cleaning device, and it is by comprising tricycle 12, cleaning system 11 and water circulation system, through cleaning worker carries out relevant operation in tricycle cab, makes each system of whole tricycle guardrail cleaning vehicle can be well Cooperate with each other to complete their designated work, and then realize the effective cleaning of the road guardrail. As shown in accompanying drawing 4, cleaning system 11 comprises the support frame 10 that is placed on tricycle 12 back box chassis 13, is provided with the cleaning brush support 11-6 that can lift on one side of support frame 10, in cleaning brush support 11- 6 is provided with a vertically arranged cleaning brush composition 11-2, the two sides and the lower part of the cleaning brush composition 11-2 are provided with a semi-open shield 11-3 for collecting cleaning water, and the cleaning brush composition 11-2 is composed of water circulation The system supplies clean water to clean the guardrail.

For example, accompanying drawing 4 is a structural schematic diagram of the cleaning system. When the cleaning vehicle is working, the engine is first started, and the power is transmitted to the support frame 10 through the transfer device 6, and then driven by the transmission gear 8, so that the support frame 10 moves to the right; When the cleaning brush composition 11-2 moved to the working position, the engine power output was switched, and the hydraulic lifting rod 11-8 began to lift the height of the cleaning brush 15. After adjusting the working position, the hydraulic lifting rod 11-8 was lowered to make the cleaning brush 15 just position; start the water circulation system to supply clean water to the cleaning brush composition 11-2, and wash, moisten and clean the guardrail.

As accompanying drawing 5 cleaning brush composition structure schematic diagram, cleaning brush composition 11-2 comprises the cleaning brush support 11-6 that horizontally arranges, and cleaning brush support 11-6 is parallel with tricycle 12 car bodies, is provided with 3 on cleaning brush support 11-6. Two screw rods 19, three screw rods 19 are arranged in parallel, the middle part of the screw rod 19 is vertically fixed with the cleaning brush support 11-6, and the two ends of each screw rod 19 are all provided with self-rotating cleaning brushes 15, and two cleaning brushes 15 are arranged respectively On both sides of the cleaning brush support 11-6, the diameter of the cleaning brush 15 fixed on the two ends of the screw rod 19 decreases gradually from front to back, so that the guardrail can be cleaned successively. It can also be designed that the first and second groups of working brushes (large) are powered by the hydraulic motor 18 for cleaning work, and the third group of working brushes (small) as driven brushes does not provide a power source. dewatering treatment.

As can be seen in accompanying drawing 5, cleaning brush 15 is connected with screw rod 19 by slide block 17, and slide block 17 is sleeved on screw rod 19, and limit spring 16 is connected on the both sides of slide block 17, and limit spring 16 It is sleeved on the outside of the screw rod 19, and the end of the limit spring 16 and the end of the screw rod 19 are fixed as a whole. Doing such a design to the cleaning brush support 11-6 is mainly to consider that some road sections will suddenly have cement piers or other objects with a width far greater than the width of the guardrail itself. When running into this type of obstacle, you can stop Manually adjust the working width of the cleaning brush 15, and use the elastic force of the limit spring 16 to make the working brush move outward through the slider 17, so as to avoid damage or aggravated wear caused by the rigid contact between the cleaning brush 15 and obstacles, thereby reducing The normal service life of cleaning brush 15. After the cleaning brush 15 crosses the obstacle, the elastic force of the limit spring 16 acts to make the cleaning brush 15 get back to the normal working position to work. Another advantage of doing such a structural design is that it is not necessary to separately design the cleaning brush 15 evasion device, because it is possible to design a suitable limit spring 16 by examining the actual working conditions (such as what obstacles will appear on the working road section). Elasticity, and according to the actual situation, adjust the elastic force of the limit spring 16 by adjusting the limit nut 14 to ensure the lateral movement range of the cleaning brush 15, thereby avoiding the rigid contact between the cleaning brush 15 and the obstacle in the working process.

When the cleaning brush 15 works, the sewage is thrown to the shield 11-3 of the cleaning brush 15 by centrifugal force, and the sewage is recycled to the sewage purifier 1 through the sewage suction pipe 11-1 for purification treatment. This design utilizes the elastic force of the spring, which can skillfully cross some obstacles encountered in the cleaning process. At the same time, because it has a supporting main shaft, which is connected to the outer support as a skeleton, it can be used as a guiding reference by taking advantage of its structural characteristics. Axis, when running into guardrail vacancy, can use it as positioning datum, align it with guardrail by observation and just can accurately put guardrail between the opposite cleaning brushes 15 under the situation that cleaning device is not adjusted. By taking the supporting spindle as the positioning reference, the cleaning workers can successfully align the guardrail and the cleaning brush 15 after a few alignment exercises. This is not only easy to operate, but also avoids the need to install a guiding mechanism, reducing the weight of the entire vehicle. While bearing weight, it also saves cost.

The structure of the slide block 17 in the present invention is one of the most important parts in the whole cleaning system, and its structural design determines the feasibility of the movement of the whole cleaning brush system, and its structure also has an impact on the service strength of the bracket, so in During the design process, two options are offered for selection. Option 1: As shown in Figure 13a, the slider is designed as T-shaped, and a cylindrical spring positioning pin is designed on the slider. In order to match the T-shaped slider support sleeve, it needs to be designed as an inner T-shaped hollow shape, that is, the slider 17 Slide in the bracket sleeve and push the slider 17 to drive the cleaning brush 15 to move laterally through the elastic force of the limit spring 16; scheme 2: as shown in Figure 13b, the slider 17 is designed as a ring-shaped sleeve, then only the cleaning brush needs to be The screw rod 19 in the system can be designed as a smooth cylinder, and the elastic force of the limit spring 16 pushes the ring-shaped slider 17 to drive the cleaning brush 15 to move laterally. Comparing the two schemes, it can be found that the processing difficulty of scheme 2 is less, and it is easy to meet the service strength, so the design method of the slider 17 and the bracket of scheme 2 is selected.

Similarly, in order to save costs, the structure of the support frame 10 is optimized, and the transmission gear 8 is used as the power input method of the support frame 10. This structural design is much simpler than the support frames currently on the market. Accompanying drawing 6 and 7 are the structural representations of support frame 10, and support frame 10 comprises vertical support bar 20 and transverse support bar 11-7, and chute 22 is set between vertical support bar 20 and chassis 13, and chute 22 Axially and radially arranged balls 21 are arranged inside, a hydraulic lifting rod 11-8 is arranged on the lateral support rod 11-7, and the hydraulic lifting rod 11-8 is connected with the cleaning brush bracket 11-6 to drive the cleaning brush bracket 11-6 up and down sports.

The kinematic pair of support frame 10 is divided into two parts, main and auxiliary, and the kinematic pair of auxiliary support frame is fixed, fixed with the chassis 13 of the tricycle compartment, and the cleaning device is driven by the vertical support bar 20 to move horizontally, and the main and auxiliary motions The movement mode of relative sliding is adopted between the pairs, that is, a smooth cylindrical sliding rod is installed between the pairs to make the main pair realize lateral movement. For the extension distance and position limit control of the support frame 10, a one-way limit spring pin can be installed between the kinematic pairs. Dead make it can not continue to protrude, when the work is finished, the support frame 10 is recovered by the characteristics that the one-way limit pin can pass in the opposite direction. A hydraulic lifting rod 11-8 is set on the lateral support rod 11-7, and its working principle of the hydraulic lifting rod 11-8 is: when the support frame 10 moves to a designated position, the hydraulic system is started by the control button in the cab, and the hydraulic lifting rod 11 -8 Bottom oil chamber inputs hydraulic oil, pushes the hydraulic lifting rod 11-8 to rise, while the hydraulic lifting rod 11-8 rises, the hydraulic oil in the upper oil chamber returns to the hydraulic oil tank, similarly when the hydraulic piston rod descends, the upper oil chamber Inject hydraulic oil, and the hydraulic oil in the oil chamber below flows back to the oil tank.

Accompanying drawing 8 and 9 are the schematic diagrams of water circulation system and sewage circulation system, can see in conjunction with accompanying drawing 3, water circulation system comprises the water tank 3 that is arranged on the chassis 13, and the water outlet 3-4 of water tank 3 passes clean water pump 23 and water spray device 24 connection, the water spray device 24 is placed directly above the cleaning brush composition 11-2, and the sewage suction pipe 11-1 is arranged in the shield 11-3 at the bottom of the cleaning brush composition 11-2, and the sewage suction pipe 11-1 is connected to the sewage pump 9, The cleaned sewage enters the sewage purifier 1 through the sewage filter 11-4, and returns to the water tank 3 to form the recycling of clean water. Turn on the water circulation device, suck the sewage collected by the shield 11-3 back to the sewage filter 11-4 through the sewage suction pipe 11-1, and transport the filtered and purified sewage back to the water tank 3, so that the sewage can be recycled, filtered and reused Effect; finally start the cleaning vehicle for cleaning work. The sewage circulation system is a set of simple sewage circulation treatment device. By recycling and filtering the sewage thrown out by the cleaning brush 15, and then introducing the treated sewage into the water tank 3 to achieve the effect of recycling, it can not only save water , to avoid the waste of water resources, can also prolong the working time of the cleaning car, and improve the working efficiency of the cleaning car.

As accompanying drawing 10 is the composition diagram of hydraulic system, hydraulic system provides power for hydraulic lifting rod 11-8 and hydraulic motor 18, and this hydraulic system comprises hydraulic oil tank 31 and hydraulic pump 30, and hydraulic pump 30 is driven by auxiliary engine 28 on one side To provide power, a reversing valve 29 is set on the connecting pipeline between the hydraulic pump 30 and the hydraulic lifting rod 11-8 and the hydraulic motor 18, and a back pressure valve 27 is set on the oil return road of the hydraulic lifting rod 11-8 and the hydraulic motor 18 .

There are only two places in the present invention that need to use the hydraulic system to provide power, namely the cleaning brush 15 power input and the hydraulic lifting rod 11-8 lifting work. Because the cleaning work needs to be carried out after the cleaning brush device works, the working hours of the hydraulic motor 18 and the hydraulic lifting rod 11-8 at 15 cleaning brushes are staggered, that is, the hydraulic motor 18 starts working after the hydraulic rod work is completed, so this The same set of hydraulic devices can be used to provide power for the two places, and the power parameters only need to meet the larger one. The working hours of the hydraulic motor 18 and the hydraulic lifting rod 11-8 are staggered, so a reversing valve 29 needs to be added in the hydraulic circuit to control the hydraulic motor 18 and the hydraulic lifting rod 11-8 to move differently through the reversing valve 29, and in order to ensure The hydraulic elevating rod 11-8 will not suddenly drop and vibrate due to the effect of gravity during the working process, and a back pressure valve 27 needs to be added in the elevating rod circuit.

As shown in accompanying drawing 11, water spray device 24 comprises the water flow pipeline 34 that is arranged in guard cover 11-3 inside, and water spray nozzle 32 is arranged at intervals on water flow pipeline 34, and water spray nozzle 32 is eighth of guard cover 11-3. angle, and point to the cleaning brush 15 in the shield 11-3, and a square guardrail 33 for supporting the water pipeline 34 is provided in the shield 11-3. Eight water spray nozzles 32 are arranged at the 8 corners of the cleaning brush cover, and the water output by the water tank 3 is pressurized by the water supply pump 2, and then sprayed onto the guardrail by the eight high-pressure water spray nozzles 32. The protective fence is wetted before cleaning. Because the general height of the guardrail is between 1000 and 1200mm, it is basically guaranteed that the entire coverage of the cleaning surface can be basically guaranteed by the diagonal arrangement of four high-pressure water spray nozzles 32 on both sides of the guardrail, and the arrangement of the water spray nozzles 32 in this way can make Clear water is effectively sprayed on the guardrail, and the clear water outside the guardrail area will be sprayed onto the cleaning brush 15 due to the influence of the spray angle of the high-pressure water spray nozzle 32, so that not only avoids clear water from being sprayed out of the cleaning area due to excessive spray pressure cause waste, the cleaning brush 15 can also be cleaned with the excess clear water sprayed, thereby greatly improving the cleaning effect of the cleaning device. Of course, the actual arrangement angle of the water spray nozzle 15 needs to be arranged according to the actual working conditions.

As shown in accompanying drawing 12, water tank 3 is water supply and water storage for cleaning vehicle, and the sewage inlet 3-1 after filtering and water injection port 3-2 are arranged on the side wall upper part of water tank 3, and water outlet 3-2 is set at water tank 3 side wall bottoms. 4. The size needs to be confirmed according to the remaining space in the washing car compartment and the actual load weight. Considering that the speed of the vehicle is not very fast, and there will be no emergency braking phenomenon without special reasons during the work process, the impact caused by water in the tank is relatively small, so the water tank 3 can be designed as a rectangular shape, so that the remaining space can be maximized. In order to prevent the free movement of water in the water tank 3 and affect the stable operation of the water supply system, a porous steady flow grid 3-3 can be designed in the water tank 3 to form a multi-layer structure inside the water tank 3 to reduce the impact of water movement in the tank. Shock caused by water supply system.
