DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of the technical scheme of the present application, the following will be described in detail in combination with the drawings and specific embodiments.

[0026] Embodiment 1

[0027] As shown in the figure, a guardrail and its reflective sign cleaning equipment, including a maintenance vehicle 1 and a cleaning mechanism 3; Figures 1-6

[0028] The maintenance vehicle 1 includes a vehicle compartment 11.

[0029] The cleaning mechanism 3 is arranged on both sides of the vehicle compartment 11 of the maintenance vehicle 1, and includes an electric telescopic rod 31 and a cleaning assembly.

[0030] One end of the electric telescopic rod 31 is connected to the vehicle compartment 11, and the other end is provided with the cleaning assembly.

[0031] The cleaning assembly includes a detachably connected upper shell 33 and a lower shell 34, and the upper shell 33 and the lower shell 34 have a channel 301 in the middle, and a spray head 35 is slidingly fitted in the channel 301.

[0032] The spray head 35 has a first state of extending out of the channel 301 and a second state of retracting into the channel 301.

[0033] The lower shell 34 is provided with a water spraying hole 341, and the water spraying hole 341 includes a first water spraying hole facing the guardrail 2 and a plurality of second water spraying holes located on both sides of the channel.

[0034] Among them, the guardrail 2 is a corrugated guardrail, and the guardrail 2 is provided with a reflective sign 21 on the surface.

[0035] The present application provides a guardrail and its reflective sign cleaning equipment, which can clean the guardrail and its reflective sign, and will not affect the service life of the reflective sign 21.

[0036] ​Specifically, the spray head 35 is extended out of the channel 301 in the first state, and the spray head 35 works with the first water spray hole on the lower surface of the lower shell 34 to spray high-pressure water or high-pressure water mist to clean the guardrail 2. As the maintenance vehicle 1 moves forward, the spray head 35 will be retracted into the channel 301 before contacting the reflective marker 21, so as not to collide with the reflective marker 21. Meanwhile, the first water spray hole on the lower surface of the lower shell 34 and the second water spray hole on both sides of the channel 301 work simultaneously, the first water spray hole cleans the surface of the guardrail 2, and the second water spray hole cleans the reflective marker 21.

[0037] When the maintenance vehicle 1 slowly drives on the emergency lane, the guardrail 2 and the reflective marker 21 beside the emergency lane can be cleaned. When the maintenance vehicle 1 drives on the inner side of the normal lane, the guardrail 2 and the reflective marker 21 on one side of the central separation strip can be cleaned. When only one side of the guardrail 2 is cleaned, the cleaning equipment on the other side is stored in the maintenance vehicle 1, so as not to affect other vehicles.

[0038] In this embodiment, in order to prevent the reflective marker 21 from colliding with the surface of the channel 301, the width of the channel 301 is greater than the width of the reflective marker 21.

[0039] As a preferred mode, the water spray hole 341 is a conical hole with a large inner diameter and a small outer diameter, which can improve the impact force of the sprayed water and improve the cleaning effect.

[0040] As a preferred mode, the upper shell 33 and the lower shell 34 are provided with through grooves in the middle, and the two through grooves cooperate to form the channel 301. Specifically, the upper shell 33 is installed on the lower shell 34 by bolts, and the two through grooves are aligned to form the channel 301.

[0041] The connecting surface of the upper shell 33 and the lower shell 34 is provided with a sealing gasket, which can improve the sealing performance of the connecting surface of the upper shell 33 and the lower shell 34, and prevent water from seeping out of the connecting surface of the upper shell 33 and the lower shell 34.

[0042] The mounting bracket 36 is arranged on the upper shell 33 opposite the channel 301, the mounting bracket 36 is partially inserted into the upper shell 33 and fixed on the upper shell 33 by bolts passing through the ear plates, the electric supporting rod 361 is arranged on the mounting bracket 36, and the output end of the electric supporting rod 361 is connected to the spray head 35 through the connecting block 362. When the electric supporting rod 361 works, it can drive the spray head 35 to retract into the channel 301, so as to avoid interference with the reflective marker 21.

[0043] The mounting bracket 36 is covered with the connecting shell 32, and the connecting shell 32 is installed on the upper shell 33. On the one hand, the connecting shell 32 plays a transmission role. On the other hand, it avoids dust and pollutants from the outside entering the channel 301.

[0044] The nozzle 35 has a limiting structure 351, and the inner wall of the passage of the upper shell 33 has a limiting sliding groove 302 matched with the limiting structure 351, which can limit the displacement distance of the nozzle 35 in the passage, so as to avoid the nozzle 35 from being abutted against the recess of the guardrail 2 when moving outward, thereby affecting the use of the nozzle.

[0045] The nozzle 35 has a mounting groove relative to the two sides of the passage 301, and the mounting groove is fixedly bonded with an elastic material 352, which can be an elastic structure such as a rubber block, and is used to block the second water spraying holes on the two sides of the passage 301, so that the second water spraying holes on the two sides of the passage 301 cannot spray water when the nozzle 35 is normally used, that is, the nozzle 35 is not retracted into the passage 301.

[0046] In order to enable the nozzle 35 to automatically enter the passage 301 when reaching the reflective sign 21, an infrared distance sensor can be arranged at the lower shell 34, and when reaching the reflective sign 21, the distance feedback by the infrared distance sensor is used to automatically control the electric supporting rod 361 to retract by the controller in the vehicle; or a fixed program is arranged, for example, when the maintenance vehicle drives at 10-20 km / h in the emergency lane, the electric supporting rod is automatically retracted every 100-120 seconds, so as to avoid the reflective sign 21.

[0047] The lower shell 34 has a cavity in which a pipeline 37 is arranged, one end of the pipeline 37 penetrates through the upper shell 33 and is connected with a water source in the vehicle compartment 11; and a corrugated hose 371 is further arranged in the passage 301, one end of the corrugated hose 371 is communicated with the nozzle 35, and the other end is communicated with the pipeline 37 outside the upper shell 33.

[0048] As a preferred mode, the upper shell 33 has the same pipeline 37 on the upper side and the lower side, and the pipeline is finally communicated with the water source in the vehicle or connected with the air source in the vehicle through a main pipe, so as to clean the guardrail 2 by spraying air.

[0049] The lower shell 34 has a positioning column 342 at each end, which is abutted against the guardrail 2. When cleaning the guardrail 2, the positioning column 342 is abutted against the guardrail 2 to form a spacing, which is more conducive to cleaning the guardrail 2 and the reflective sign 21 by high-pressure water or air.

[0050] In the embodiment, the spacing is about 2 cm.

[0051] The positioning column 342 is made of flexible material and is not easy to be damaged; and the lower shell 34 is in an arc shape, which can be more fitted to the wave-shaped guardrail 2 and can provide certain supporting force, so that the electric telescopic rod 31 does not need to provide all the supporting force.

[0052] The cleaning equipment of the present application can clean the guardrails and the reflectors on different lanes of the highway, and has better effect and higher efficiency than the prior cleaning method. In the cleaning process, other vehicles are not affected. When not in use, the cleaning equipment can be completely stored in the maintenance vehicle.

[0053] The above is only the preferred embodiment of the present application, and the protection scope of the present application is defined by the scope of the claims. The several improvements and refinements made by the skilled in the art without departing from the spirit and scope of the present application should also be considered as the protection scope of the present application.
