Description

Technical Field

[0001] This utility model relates to the technical field of centerline positioning aids, specifically a road centerline positioning aid. Background Technology

[0002] During road surveying and mapping, it is necessary to locate the centerline of the road and perform auxiliary measurements. Therefore, a centerline locator is needed to locate the centerline during road surveying, which can assist in road measurement.

[0003] In practical applications, existing road centerline positioning aids have relatively complete structures and functions, and can basically meet daily usage needs. However, the following problems still exist:

[0004] In actual use, the width of roads varies, while the width of the centerline positioning device is fixed. As a result, the centerline positioning device cannot be perfectly aligned with both sides of the road when positioning the centerline on roads of different widths. This makes the overall centerline positioning rely on the laser positioning device for assistance, which will accumulate errors and increase the overall error value.

[0005] Therefore, this utility model provides a road centerline positioning aid. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a road centerline positioning aid.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a road centerline positioning aid, comprising a rectangular frame, wherein a mounting plate is fixedly connected between the two sides of the rectangular frame; an adjustment and moving structure is provided on the top of the mounting plate, the adjustment and moving structure comprising a rectangular frame, the bottom of the rectangular frame being fixedly connected to the top of the mounting plate, a first motor being fixedly installed on one side of the rectangular frame, and a threaded rod being fixedly connected to the output end of the first motor; an anti-sway retraction structure is provided on the bottom of the mounting plate, the anti-sway retraction structure comprising a U-shaped plate, the top of the U-shaped plate being fixedly connected to the bottom of the mounting plate, an auxiliary rotating rod being rotatably arranged between the two sides of the inner wall of the U-shaped plate, and a winding roller being fixedly connected to the outer surface of the auxiliary rotating rod.

[0008] In a preferred embodiment, the threads at both ends of the threaded rod have opposite directions, and two threaded hole blocks are symmetrically threaded onto the outer surface of the threaded rod. A sliding block is fixedly connected to the top of each threaded hole block. A fixing rod is fixedly connected between the two sides of the rectangular frame. The sliding block is slidably disposed on the outer surface of the fixing rod. An auxiliary connecting rod is fixedly connected to the top of the sliding block. A movable plate is fixedly connected to one end of the auxiliary connecting rod, and two movable wheels are symmetrically installed at the bottom of the movable plate.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded rod and the threaded hole block, the two auxiliary connecting rods can be driven to move, which in turn can drive the moving plate and the moving wheel to move. Then, the position of the moving wheel can be adjusted according to the width of the road, so that the moving wheels on both sides fit with the edges of the road, thus facilitating the positioning of the road centerline.

[0010] In a preferred embodiment, one end of the auxiliary rotating rod passes through the U-shaped plate and is fixedly connected to an operating block. The inner wall of the operating block is threadedly connected to a threaded clamping rod. A threaded clamping hole is provided on one side of the U-shaped plate. A traction rope is wound around the outer surface of the winding roller, and a drawing ink fountain is fixedly connected to the bottom end of the traction rope.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded clamp and the threaded clamp hole, the winding roller can be fixed, and in turn, the marking ink fountain and the traction rope can be fixed.

[0012] In a preferred embodiment, a connecting rod is fixedly connected to one side of the U-shaped plate, and a limiting circular frame is fixedly connected to one end of the connecting rod.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the limiting circular frame, the traction rope can be guided, and at the same time, the traction rope can be prevented from swaying too much, which would affect the normal use of the ink line marker.

[0014] This utility model provides a road centerline positioning aid. It has the following beneficial effects:

[0015] By setting up an adjustable moving structure, the auxiliary connecting rod and moving plate can be driven to move under the action of the threaded rod and threaded hole block, thereby adjusting the position of the moving wheels on both sides. This allows the moving wheels to be adjusted according to the actual width of the road, so that the moving wheels can be located at the two edges of the road. This facilitates the centerline positioning of roads of different widths, with the bottom of the limiting circle frame serving as the road centerline, thus facilitating line drawing operations. By setting up an anti-sway storage structure, the traction rope can be stored under the action of the winding roller, thus preventing the traction rope from becoming tangled. At the same time, the limiting circle frame can guide and limit the traction rope, allowing the ink marker to draw the road centerline. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, this embodiment provides a technical solution: a road centerline positioning aid, including a rectangular frame 1, with a mounting plate 2 fixedly connected between the two sides of the rectangular frame 1; an adjustment and moving structure 3 is provided on the top of the mounting plate 2, the adjustment and moving structure 3 including a rectangular frame 31, the bottom of the rectangular frame 31 being fixedly connected to the top of the mounting plate 2, a first motor 32 being fixedly installed on one side of the rectangular frame 31, and a threaded rod 33 being fixedly connected to the output end of the first motor 32; an anti-sway retraction structure 4 is provided at the bottom of the mounting plate 2, the anti-sway retraction structure 4 including a U-shaped plate 41, the top of the U-shaped plate 41 being fixedly connected to the bottom of the mounting plate 2, an auxiliary rotating rod 42 being rotatably arranged between the two sides of the inner wall of the U-shaped plate 41, and a winding roller 44 being fixedly connected to the outer surface of the auxiliary rotating rod 42, which can be adjusted by setting... The movable structure 3, under the action of the threaded rod 33 and the screw hole block 35, can drive the auxiliary connecting rod 37 and the movable plate 38 to move, thereby adjusting the position of the movable wheels 39 on both sides. This allows the movable wheels 39 to be adjusted according to the actual width of the road, so that the movable wheels 39 can be located at the two edges of the road, thus facilitating the centerline positioning of roads of different widths. That is, the bottom of the limiting circle frame 48 is the centerline of the road, which facilitates the line drawing operation. By setting the anti-sway storage structure 4, under the action of the winding roller 44, the traction rope 49 can be driven to be stored, thus preventing the traction rope 49 from being messy and tangled. At the same time, under the action of the limiting circle frame 48, the traction rope 49 can be guided and limited, so that the line drawing ink fountain 410 can perform the line drawing operation on the centerline of the road.

[0026] Going further, such as Figures 2-3 As shown: The threads at both ends of the threaded rod 33 have opposite directions. Two threaded hole blocks 35 are symmetrically threaded on the outer surface of the threaded rod 33. A sliding block 36 is fixedly connected to the top of the threaded hole block 35. A fixed rod 34 is fixedly connected between the two sides of the rectangular frame 31. The sliding block 36 is slidably disposed on the outer surface of the fixed rod 34. An auxiliary connecting rod 37 is fixedly connected to the top of the sliding block 36. A movable plate 38 is fixedly connected to one end of the auxiliary connecting rod 37. Two movable wheels 39 are symmetrically installed at the bottom of the movable plate 38. Under the action of the threaded rod 33 and the threaded hole blocks 35, the two auxiliary connecting rods 37 can be driven to move, which in turn can drive the movable plate 38 and the movable wheels 39 to move. The position of the movable wheels 39 can be adjusted according to the width of the road, so that the movable wheels 39 on both sides fit with the edges of the road, thus facilitating the positioning of the road centerline.

[0027] The above solutions also have the problem that when the traction ropes 49 are not in use, they are prone to tangling, which increases the subsequent cleaning costs. Figure 4As shown: In this scheme, one end of the auxiliary rotating rod 42 passes through the U-shaped plate 41 and is fixedly connected to the operating block 43. The inner wall of the operating block 43 is threadedly connected to the threaded clamp rod 46. A threaded clamping hole 45 is opened on one side of the U-shaped plate 41. A traction rope 49 is wound around the outer surface of the winding roller 44. The bottom end of the traction rope 49 is fixedly connected to the drawing ink fountain 410. Under the action of the threaded clamp rod 46 and the threaded clamping hole 45, the winding roller 44 can be fixed, and thus the drawing ink fountain 410 and the traction rope 49 can be fixed.

[0028] The above solutions also have the problem that the traction rope 49 is prone to significant swaying, which in turn affects the normal use of the ink marker 410. Figure 4 As shown, a connecting rod 47 is fixedly connected to one side of the U-shaped plate 41, and a limiting circle frame 48 is fixedly connected to one end of the connecting rod 47. Under the action of the limiting circle frame 48, the traction rope 49 can be guided, and the traction rope 49 can be prevented from shaking too much, which would affect the normal use of the ink line marker 410.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] In use: At this time, according to the actual width of the road, the first motor 32 is started, so that the first motor 32 can drive the threaded rod 33 to rotate, which in turn can drive the threaded hole block 35 to move, which in turn can drive the auxiliary connecting rod 37 to move, which in turn can drive the moving plate 38 and the moving wheel 39 to move.

[0032] This allows the movable wheel 39 to fit against the edges of the road on both sides. At this time, rotating the operating block 43 causes the winding roller 44 to rotate, which in turn drives the traction rope 49 to rotate, thereby driving the traction rope 49 and the ink fountain 410 to move, thus facilitating the line drawing operation. At the same time, under the action of the limiting frame 48, the traction rope 49 will not shake significantly during use.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
