With its advantages of fast speed, high efficiency, accuracy, etc., the line marking mechanism has played a huge role in urban planning and highway construction, saving the construction period and economic investment of road surface construction to the greatest extent.

[0003] The existing line marking mechanism for highway construction is composed of a spray gun, a vehicle frame, a gasoline engine and a paint conveying component. The paint for road markings is loaded in the paint conveying component, so that the paint is conveyed into the spray gun and sprayed out on the road surface to realize line marking. However, there are the following defects:

[0004] (1) When the existing line marking mechanism for highway construction is used for highway line marking construction, due to the unevenness of the existing road surface, when line marking construction is carried out on the uneven road surface, the spraying height between the spray gun and the road surface changes, and then the thickness of the road construction line marking changes, resulting in the problem of reducing the accuracy of highway line marking. For this reason, we propose a line marking mechanism for highway construction. Content of the Utility Model

[0005] The purpose of the utility model is to provide a line marking mechanism for highway construction, so as to solve the problem that when the line marking mechanism for highway construction is used for line marking construction on an uneven road surface, the construction height is likely to change, the thickness of the line marking changes, and the accuracy of line marking construction is reduced, which is put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a line marking mechanism for highway construction, including a vehicle frame, a paint conveying component is arranged on the top of the vehicle frame, a spray gun is arranged on one side of the vehicle frame, an assembly frame is fixed on the side wall of the vehicle frame, a movable block is movably arranged inside the assembly frame, a sliding hole is opened on the surface of the movable block, a sliding rod penetrates through the inside of the sliding hole, the sliding rod is fixed on the inner wall of the assembly frame, a cross frame is fixed on the surface of the movable block, a support cylinder is fixed at the bottom of one end of the cross frame, an adjusting rod is slidably connected inside the support cylinder, a plurality of locking holes are opened on the surface of the adjusting rod, a jack is opened on the outer wall of the support cylinder, and a locking pin is commonly inserted between the jack corresponding to the locking hole. The spray gun is installed at the bottom of the cross frame.

[0007] Preferably, a spring is sleeved on the outer wall of the sliding rod, and the spring is located on the top of the movable block.

[0008] Preferably, an external thread is arranged on the surface of the sliding rod, and a nut is connected to the external thread by threading.

[0009] Preferably, there are two sliding rods, and the two sliding rods are circularly arranged about the central axis of the movable block.

[0012] Preferably, a through hole is formed on the surface of one end of the locking pin, and a circular pull ring is embedded in the through hole.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) Through the designed assembly frame, movable block, sliding rod, cross frame, support cylinder, adjusting rod, lock hole and locking pin, the cross frame equipped with a spray gun is slidably installed in the assembly frame through the movable block. The sliding rod is located in the sliding hole to limit the position of the movable block in the assembly frame and prevent it from detaching. After inserting the adjusting rod into the support cylinder and making it insert to an appropriate depth, insert the locking pin into the lock hole and the jack hole to fix the position of the adjusting rod. Through the cooperation of the adjusting rod and the support cylinder, support and fix the construction height of the spray gun. During the line marking construction, the bottom surface of the adjusting rod is always in contact with the road surface, and the cross frame is movable. Therefore, when there are depressions on the road surface, the adjusting rod also moves up and down following the depressions of the road surface, thereby driving the cross frame equipped with the spray gun to adjust the height in a timely manner, ensuring that the line marking construction height of the spray gun always remains consistent with the road surface, making the line marking thickness uniform and accurate. Through the designed spring, the spring exerts an elastic extrusion force on the movable block, causing the cross frame to produce a downward pressing effect under the action of the spring to prevent the cross frame from jumping without pressure. Through the designed nut and external thread, rotate the nut, and the nut and the external thread are screwed. By screwing, adjust the position of the nut to realize the adjustment of the initial compression amount of the spring to make it achieve the best elastic effect. Through the designed roller and bottom groove, a bottom groove is formed at the contact position between the adjusting rod and the ground, and a roller is installed in the bottom groove. The roller can roll in the bottom groove, thereby playing a lubricating role and avoiding abrasion between the adjusting rod and the road surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiment

[0022] Please refer to Figures 1 to 4, the utility model provides a technical solution: a line marking mechanism for highway construction, including a vehicle frame 1. A paint conveying component 2 is arranged on the top of the vehicle frame 1, and a spray gun 3 is arranged on one side of the vehicle frame 1. An assembly frame 11 is fixed on the side wall of the vehicle frame 1. An activity block 16 is movably arranged inside the assembly frame 11. A sliding hole 18 is formed on the surface of the activity block 16, and a sliding rod 15 penetrates through the inside of the sliding hole 18. The sliding rod 15 is fixed on the inner wall of the assembly frame 11. A cross frame 10 is fixed on the surface of the activity block 16. A support cylinder 9 is fixed at the bottom of one end of the cross frame 10. An adjusting rod 5 is slidably connected inside the support cylinder 9. A plurality of locking holes 7 are formed on the surface of the adjusting rod 5. A jack 4 is formed on the outer wall of the support cylinder 9. A locking pin 8 is inserted between the corresponding locking holes 7 of the jack 4. Through the designed assembly frame 11, activity block 16, sliding rod 15, cross frame 10, support cylinder 9, adjusting rod 5, locking holes 7 and locking pin 8, the cross frame 10 equipped with the spray gun 3 is slidably installed inside the assembly frame 11 through the activity block 16. The sliding rod 15 is located inside the sliding hole 18 to limit the position of the activity block 16 inside the assembly frame 11 and prevent it from detaching. The adjusting rod 5 is inserted into the support cylinder 9. After inserting it to an appropriate depth, the locking pin 8 is inserted into the locking holes 7 and the jack 4 to fix the position of the adjusting rod 5. Through the cooperation of the adjusting rod 5 and the support cylinder 9, the construction height of the spray gun 3 is supported and fixed. During line marking construction, the bottom surface of the adjusting rod 5 is always in contact with the road surface, and the cross frame 10 is movable. Therefore, when there are depressions on the road surface, the adjusting rod 5 also moves up and down following the depressions of the road surface, thereby driving the cross frame 10 equipped with the spray gun 3 to adjust the height in time, ensuring that the line marking construction height of the spray gun 3 always remains consistent with the road surface, making the line marking thickness uniform and accurate. The spray gun 3 is installed at the bottom of the cross frame 10.

[0023] In this embodiment, preferably, a spring 14 is sleeved on the outer wall of the sliding rod 15. Through the designed spring 14, the spring 14 exerts an elastic extrusion effect on the activity block 16, causing the cross frame 10 to produce a downward pressing effect under the action of the spring 14 to avoid the cross frame 10 jumping without pressure. And the spring 14 is located at the top of the activity block 16. An external thread 12 is arranged on the surface of the sliding rod 15, and a nut 13 is threadedly connected to the external thread 12. Through the designed nut 13 and external thread 12, when the nut 13 is rotated, the nut 13 and the external thread 12 are threadedly screwed. By threaded screwing, the position of the nut 13 is adjusted to realize the adjustment of the initial compression amount of the spring 14 to make it reach the best elastic effect. There are two sliding rods 15, and the two sliding rods 15 are circularly arranged about the central axis of the activity block 16.

[0024] In this embodiment, preferably, a bottom groove 17 is formed at the bottom of the adjusting rod 5. A roller 6 is rotatably connected to the inner side of the bottom groove 17. Through the designed roller 6 and bottom groove 17, the bottom groove 17 is formed at the contact position between the adjusting rod 5 and the ground, and the roller 6 is installed in the bottom groove 17. The roller 6 can roll in the bottom groove 17, thereby playing a lubricating role and avoiding wear between the adjusting rod 5 and the road surface. The cross-sections of both the adjusting rod 5 and the support cylinder 9 are rectangular structures, and the central axes of the adjusting rod 5 and the support cylinder 9 coincide with each other. A through hole is formed on the surface of one end of the locking pin 8, and a circular pull ring is inlaid on the through hole.

[0025] The working principle and usage process of the present utility model: In the present utility model, the cross frame 10 equipped with the spray gun 3 is slidably installed in the assembly frame 11 through the movable block 16. The slide rod 15 is located in the slide hole 18 to limit the position of the movable block 16 in the assembly frame 11 and prevent it from detaching. By rotating the nut 13, the nut 13 is threadedly screwed with the external thread 12. By threaded screwing, the position of the nut 13 is adjusted to achieve the adjustment of the initial compression amount of the spring 14, so as to make it achieve the best elastic effect. After inserting the adjusting rod 5 into the support cylinder 9 and inserting it to an appropriate depth, the locking pin 8 is inserted into the locking hole 7 and the jack hole 4 to fix the position of the adjusting rod 5. Through the cooperation of the adjusting rod 5 and the support cylinder 9, the construction height of the spray gun 3 is supported and fixed. During the line marking construction, the bottom surface of the adjusting rod 5 always fits the road surface. The spring 14 exerts an elastic extrusion force on the movable block 16, causing the cross frame 10 to produce a downward pressure effect under the action of the spring 14 to prevent the cross frame 10 from jumping due to the lack of pressure. Moreover, the cross frame 10 is movable. Therefore, when there are depressions on the road surface, the adjusting rod 5 also moves up and down following the depressions on the road surface, thereby driving the cross frame 10 equipped with the spray gun 3 to adjust the height in a timely manner, ensuring that the line marking construction height of the spray gun 3 always remains consistent with the road surface, and making the line marking thickness uniform and accurate.
