DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Referring to Figs. 1 to 4 The utility model provides a kind of embodiment: a lane line marking device,

[0021] Including bottom plate 11, bottom plate 11 is the support that overall device provides, drive installation on bottom plate 11 on material spraying mechanism 20, turnover mechanism 30 and telescopic mechanism 40 are moved along curbstone together.

[0022] The side of bottom plate 11 is provided with one and more bases 12;

[0023] When base 12 is one, turnover mechanism 30 and telescopic mechanism 40 installed on base 12 are also one. When base 12 is installed at any place on the side of base 12, staff can rely on turnover mechanism 30 and telescopic mechanism 40 installed on base 12 to push marking device along curbstone. But because base 12 is only one, turnover mechanism 30 and telescopic mechanism 40 on base 12 can only provide one support force for bottom plate 11, so the side of bottom plate 11 is not enough uniform stress. Therefore staff in the push bottom plate 11 moves while controlling the advancing direction of marking device, unnecessary physical consumption is caused to staff.

[0024] When base 12 is two and more, turnover mechanism 30 and telescopic mechanism 40 installed on base 12 are also two and more. Such design can provide two and more support forces for the side of bottom plate 11. Two and more support forces can guarantee that the side of bottom plate 11 is uniformly stressed, staff can rely on curbstone to advance when pushing bottom plate 11 to move, do not need to control the advancing direction of marking device. Therefore when base 12 is two and more, unnecessary physical consumption of staff can be reduced.

[0025] Each base 12 is installed with turnover mechanism 30;Each turnover mechanism 30 includes fixed sleeve 31, rotating rod 32, clamping sleeve 33 and clamp 34;The bottom of each fixed sleeve 31 is connected with base 12;Rotating rod 32 is installed in the inside of each fixed sleeve 31;Clamping sleeve 33 is installed on the side of each fixed sleeve 31;Clamp 34 is installed on the outside of each clamping sleeve 33;

[0026] The turnover mechanism 30 is connected together through the fixed sleeve 31 and the base 12. When the clamp hoop 34 is not tightened, the rotating rod 32 can rotate inside the fixed sleeve 31 and the clamping sleeve 33, thereby driving the telescopic rod 41 of the telescopic mechanism 40 to adjust the angle. When the staff finds that the guide wheel 44 cannot completely fit the curb because the road surface and the curb are not perpendicular to each other, the staff adjusts the angle between the guide wheel 44 and the curb by rotating the telescopic rod 41 connected with the rotating rod 32. After the staff adjusts the guide wheel 44 to completely fit the curb, the staff tightens the bolt on the clamp hoop 34.

[0027] After being tightened, the clamp hoop 34 shrinks and presses the clamping sleeve 33, and the pressure is transmitted from the clamping sleeve 33 to the rotating rod 32. By increasing the pressure between the clamping sleeve 33 and the rotating rod 32, the friction between the clamping sleeve 33 and the rotating rod 32 is increased, thereby limiting the rotation of the rotating rod 32 in the clamping sleeve 33, and fixing the angle between the telescopic rod 41 and the bottom plate 11.

[0028] Each rotating rod 32 is provided with a telescopic mechanism 40; each telescopic mechanism 40 comprises a telescopic rod 41, a fixing screw 42, a connecting rod 43 and a guide wheel 44; the bottom of each telescopic rod 41 is installed on the rotating rod 32; the inside of each telescopic rod is slidably connected with the connecting rod 43;

[0029] The connecting rod 43 of the telescopic mechanism 40 can be telescoped in the inside of the telescopic rod 41. When the distance between the curb and the guide wheel 44 is far, the connecting rod 43 can be extended from the inside of the telescopic rod 41, increase the length of the connecting rod 43 exposed outside the telescopic rod 41, and make the guide wheel 44 contact with the curb. When the distance between the curb and the guide wheel 44 is too close, the connecting rod 43 can be retracted into the inside of the telescopic rod 41, reduce the length of the connecting rod 43 exposed outside the telescopic rod 41, and make the guide wheel 44 contact with the curb.

[0030] The end of each telescopic rod 41 away from the rotating rod 32 is threadedly connected with the fixing screw 42; the end of each connecting rod 43 away from the telescopic rod 41 is provided with the guide wheel 44.

[0031] When the fixing screw 42 penetrates the inner wall of the telescopic rod 41, the end of the fixing screw 42 contacts the surface of the connecting rod 43. As the fixing screw 42 continues to screw in, the pressure of the contact surface between the fixing screw 42 and the connecting rod 43 also gradually increases, thereby locking the position of the connecting rod 43 in the inside of the telescopic rod 41, and stably maintaining the current positional relationship between the telescopic rod 41 and the connecting rod 43, preventing the connecting rod 43 from freely moving relative to the telescopic rod 41 and affecting the actual application effect.

[0032] Specifically, the base 12 is further provided with a material spraying mechanism 20; the material spraying mechanism 20 comprises a material cylinder 21, a barrel cover 22, a suction pump 24 and a spraying head 23; the bottom of the material cylinder 21 is connected with the base 12; the top of the material cylinder 21 is provided with the barrel cover 22; the spraying head 23 is installed on the side of the bottom plate 11; the suction pump 24 is connected with the material cylinder 21 at the inlet end and connected with the spraying head 23 at the outlet end and installed on the bottom plate 11.

[0033] The material cylinder 21 of the material spraying mechanism 20 is used for storing paint used in the line marking work. The paint enters the inside of the material cylinder 21 from the barrel cover 22 at the top of the material cylinder 21. After the worker opens the suction pump 24, the paint stored in the inside of the material cylinder 21 enters the inside of the suction pump 24 from the inlet of the suction pump 24, flows out from the outlet of the suction pump 24 through the pressurization of the suction pump 24 and enters the spraying head 23. The paint pressurized by the suction pump 24 is sprayed from the spraying head 23 and sprayed on the road surface by the spraying head 23, so as to complete the line marking work.

[0034] Specifically, the bottom plate 11 is provided below with a plurality of universal wheels 14 and a plurality of directional wheels 13, which provide support for the bottom plate 11, and the universal wheels 14 can provide steering ability for the line marking device and help the line marking device to approach the curb.

[0035] Specifically, the bottom plate 11 is further provided with a handle 15, which can provide a suitable pushing height for the worker.

[0036] Working principle:

[0037] In actual use, the worker parks the line marking device near the area to be marked on the roadside.

[0038] Next, the worker compares the length of the telescopic mechanism 40 on the base 12 with the distance between the base 12 and the curb. According to the comparison result, the telescopic mechanism 40 is adjusted: if the distance between the curb and the guide wheel 44 is far, the connecting rod 43 is pulled out from the inside of the telescopic rod 41; if the distance between the curb and the guide wheel 44 is too close, the connecting rod 43 is retracted into the inside of the telescopic arm.

[0039] After the worker completes the adjustment of the telescopic mechanism 40, the fixed screw 42 on the telescopic rod 41 is gripped and screwed into the inside of the telescopic rod 41, so as to fix the connecting rod 43 in the inside of the telescopic rod 41.

[0040] When the worker adjusts the length of the telescopic mechanism 40, the worker observes whether the road surface is flat. When the worker finds that the road surface is not flat or the road surface is not perpendicular to the curb, the worker holds the telescopic rod 41 with the adjusted length. The worker holds the telescopic rod 41 and adjusts the angle of the guide wheel 44 through the rotating rod 32 of the turnover mechanism 30. When the worker turns the telescopic rod 41 to the appropriate angle, i.e. the guide wheel 44 is in contact with the curb, the worker uses a tool to tighten the bolt on the clamp 34, and the clamp 34 will extrude the clamping sleeve 33 to help the clamping sleeve 33 fix the rotating rod 32. At this time, the rotating rod 32 is at the appropriate angle inside the fixing sleeve 31.

[0041] When the worker repeats the above operation to adjust all the turnover mechanisms 30 and telescopic mechanisms 40 installed on the bottom plate 11, the worker opens the suction pump 24. The worker holds the handle 15 and leans the bottom plate 11 against the curb through the universal wheels 14 below the bottom plate 11. The worker pushes the handle 15 and moves forward through the universal wheels 14 and the directional wheels 13 below the bottom plate 11.

[0042] When the marking device moves forward, the paint enters the matching spray head 23 from the cartridge 21 through the suction pump 24. The worker pushes the marking device to drive the spray head 23 to complete the marking work on the area to be marked.

[0043] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and it is intended to encompass all changes falling within the meaning and scope of equivalents of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
