Description

Technical Field

[0001] The utility model relates to the technical field of road repair, in particular to a road caulking device for road engineering. Background Technique

[0002] Pavement damage can generally be divided into two categories: structural damage and functional damage. Structural damage leads to a decline in the bearing capacity of the pavement structure and is manifested in the form of various structural cracks. Functional damage will affect the driving quality and driving safety, manifested as a decline in the pavement serviceability, a reduction in flatness and skid resistance. There are generally many cracks on the highway. For such cases that do not require major rectification, they can generally be filled with a filling agent.

[0003] The patent document with the publication number CN219240239U discloses a road caulking device for road engineering, and puts forward the problem that "the existing road caulking device does not have a drying function. When repairing the road surface, it often takes a long time to wait until the road surface to be repaired dries before the next section of the road surface can be repaired, which greatly wastes manpower and material resources. Moreover, when it rains or is cloudy, the waiting time for the road surface to dry will be even longer", and solves the problem.

[0004] However, in the above-mentioned prior art, the output of the filling agent is directly carried out by opening and closing the automatic valve, so as to carry out the caulking operation. The discharge amount cannot be controlled. If the discharge speed is fast, it is easy to overfill, resulting in material waste. If the crack is large and the discharge speed is slow, it will affect the work efficiency. Therefore, a new road caulking device for road engineering is proposed to optimize the above-mentioned prior art. Content of the Utility Model

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a road caulking device for road engineering includes a bottom plate 1. One side of the top surface of the bottom plate 1 is fixedly installed with a barrel body 2. A repair agent is provided in the barrel body 2, and the repair agent adopts cold patch liquid caulking glue. The outside of the barrel body 2 is provided with a pump body 3 fixedly installed on the bottom plate 1. The outside of the pump body 3 is provided with a regulating valve plate 4 fixedly installed on the bottom plate 1. The inlet of the regulating valve plate 4 is connected to the pump body 3 through a pipeline. The input end of the pump body 3 is communicated with the barrel body 2 through a pipeline. The regulating valve plate 4 is provided with two outlets. The outlets of the regulating valve plate 4 are respectively connected with a caulking head 5 and a return pipe 6. The caulking head 5 extends to the outside of the bottom plate 1. One end of the return pipe 6 is fixedly connected to the top of the barrel body 2 and is communicated. The inner side of the regulating valve plate 4 is provided with a first communication cavity 7 corresponding to the two outlets. A valve core 8 adapted to it is slidably connected in the regulating valve plate 4. A flow-through hole 9 is opened in the middle of the valve core 8. The flow-through hole 9 communicates the two first communication cavities 7 at the same time. The valve core 8 is provided with a second communication cavity 10 corresponding to the inlet of the regulating valve plate 4. The second communication cavity 10 is always communicated with the inlet during the sliding process of the valve core 8. The second communication cavity 10 is communicated with the flow-through hole 9. The top surface of the regulating valve plate 4 is rotationally penetrated and connected with a threaded turning handle 11. One end of the threaded turning handle 11 is inserted into the valve core 8 and is threadedly connected with the valve core 8. A threaded hole for threaded connection of the threaded turning handle 11 is opened on the valve core 8. The bottom surface of the bottom plate 1 is also fixedly connected with a scraping plate 27. The scraping plate 27 corresponds to the caulking head 5.

[0026] Through the arrangement of the scraping plate 27, the excess filling agent can be scraped flat after the caulking head 5 fills the gap, so as to keep the road surface flat.

[0027] The pump body 3 stably and evenly outputs the repair agent in the barrel body 2 outward. During the output process, the adjustment of the valve core 8 can control the sizes of the flow-through holes 9 corresponding to the two first communication cavities 7, and control the proportion of the caulking agent flowing to the caulking head 5 and the return pipe 6 respectively, so as to control the caulking flow rate. The caulking flow rate can be controlled according to the size of the crack, avoiding the problems of too fast discharging speed, easy overfilling and material waste, and too slow discharging speed, affecting work efficiency.

[0028] On the other side of the top surface of the bottom plate 1, a dust collection box 12 and a mobile power supply 13 are fixedly installed, and a switch 26 is installed on the mobile power supply 13.

[0029] A handle 14 is fixedly installed on the tops of the dust collection box 12 and the mobile power supply 13 together, and casters 15 are installed at the four corners of the bottom surface of the bottom plate 1.

[0030] The device can be conveniently moved through the cooperation of the handle 14 and the casters 15.

[0031] A suction fan 16 communicated with the dust collection box 12 is installed on the top surface of the dust collection box 12. A blowing pump 17 is also fixedly installed on the top surface of the dust collection box 12. A dust suction hood 18 is fixedly installed on the front side of the bottom plate 1 corresponding to the caulking head 5. A nozzle 19 is fixedly connected through the middle of the dust suction hood 18. The nozzle 19 is communicated with the air outlet end of the blowing pump 17 through a pipeline. The air inlet end of the blowing pump 17 is communicated with the inner top of the dust collection box 12 through a pipeline. The dust suction hood 18 is fixedly connected and communicated with the middle of the dust collection box 12 through a pipeline, and a filter screen plate 20 is fixedly installed on the upper part inside the dust collection box 12.

[0032] A cleaning port 21 is provided on the dust collection box 12, and a sealing plate 22 fixedly installed with the dust collection box 12 through bolts is provided outside the cleaning port 21.

[0033] Through the settings of the blowing pump 17 and the suction fan 16, a double-layer suction effect can be achieved, and dust filtration is carried out in cooperation with the filter screen plate 20, so as to suck dust at the position blown by the nozzle 19 through the dust suction hood 18, effectively reducing the diffusion of dust generated when the air pump 17 blows through the nozzle 19.

[0034] Two shells 23 are fixedly connected in parallel on one side of the dust collection box 12 corresponding to the caulking head 5. An electric heating grid 24 is fixedly installed inside the shells 23, and a blowing fan 25 is fixedly installed on the inner top of the shells 23.

[0035] Through the cooperation of the blowing fan 25 and the electric heating grid 24, hot air can be blown downward through the shells 23, thereby accelerating the drying of the caulking agent.

[0036] The switch 26 is electrically connected to the mobile power supply 13 through a wire, and the pump body 3, the suction fan 16, the blowing pump 17, the electric heating grid 24 and the blowing fan 25 are all electrically connected to the switch 26 through wires.

[0037] The working principle of the present utility model is as follows:

[0038] During use, sealant is added into the barrel body 2. At this time, the device is moved to the position beside the road crack through the handle 14 and the casters 15, so that the air nozzle 19 and the caulking head 5 are aligned with the crack. Meanwhile, the device is moved along the crack. At this time, the mobile power source 13 is powered on by controlling the switch 26, thereby starting the pump body 3, the exhaust fan 16, the air blowing pump 17, the electric heating grid 24 and the air blowing fan 25. Then, the air blowing pump 17 blows out the dust and particulate impurities in the crack through the air nozzle 19. Meanwhile, under the action of the exhaust fan 16 and the air blowing pump 17, suction is carried out through the dust suction cover 18, so that the dust and impurities are sucked into the dust collection box 12. Further filtered by the dust filter screen plate 20, the dust remains in the dust collection box 12. The pump body 3 pumps out the sealant in the barrel body 2. Part of it is filled into the road crack through the caulking head 5, and part of it flows back into the barrel body 2 through the return pipe 6, thereby repairing the crack. Meanwhile, during the movement of the device, the sealant at the crack position is scraped flat by the scraping plate 27. Further, hot air is blown to the filling agent filled in the crack through the air blowing fan 25 and the electric heating grid 24, thereby accelerating the drying of the filling agent.

[0039] When caulking with the caulking head 5, the threaded turning handle 11 can be rotated, thereby controlling the position of the valve core 8 on the regulating valve plate 4, and thus controlling the corresponding situation between the flow through hole 9 and the first communication cavity 7. The sealant can enter the regulating valve plate 4 and then enter the flow through hole 9 through the second communication cavity 10. The sealant passing through the flow through hole 9 is divided by the two first communication cavities 7 and enters the caulking head 5 and the return pipe 6 respectively. The flow rate is controlled by the overlapping size of the flow through hole 9 and the two first communication cavities 7 respectively. The total output of the pump body 3 remains unchanged, and the flow rate with a larger overlap will be larger.

[0040] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
