Description

Technical Field

[0001] The invention relates to a marking device, in particular to a marking device for road and bridge construction, belonging to the field of road and bridge construction. Background Art

[0002] Roads and bridges generally consist of several major components: the roadbed, pavement, bridges, tunnels, and transportation infrastructure. The roadbed is a linear structure constructed of soil or stone. It bears the weight of the rock and soil, the gravity of the pavement, and the traffic loads transmitted from the pavement, making it a crucial component of the overall highway structure. The roadbed primarily includes the roadbed, side slopes, side ditches, and other ancillary facilities. The pavement is a layered structure constructed of various road-building materials or mixtures, laid in layers on the roadbed for vehicle travel. Its function is to ensure stable, high-speed, comfortable, safe, and economical operation of vehicles on the road in all weather conditions. The pavement typically consists of the pavement, shoulders, curbs, and a median. The pavement can be further divided into lanes, sidewalks, and curbs in the transverse direction.

[0003] After the construction of roads and bridges is completed, it is often necessary to manually mark lines on straight roads. According to road construction standards, when dividing the road dotted lines, it is necessary to ensure that the length and interval of each marked area are consistent. This means that manual marking requires manual measurement before printing using templates, which is extremely inconvenient and leads to low construction efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a marking device for road and bridge construction to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a marking device for road and bridge construction, comprising a box body, one side of the box body is fixedly connected to a handrail, the upper side of the box body is fixedly embedded with a hopper, the lower rear side of the box body is symmetrically provided with two universal wheels, a receiving groove is provided in the middle of the lower side of the box body, both sides of the receiving groove and located in the box body are provided with roller cavities, a rotating rod is provided in the roller cavity, a paint roller is fixedly sleeved on the outer side of the middle part of the rotating rod, a guide rod is rotatably sleeved on the outer side of both ends of the rotating rod, one end of the guide rod extends out of the roller cavity and is fixedly connected to a No. 2 spring, the end of the No. 2 spring away from the guide rod is respectively fixedly connected to the inner wall of the box body, a horizontal plate is fixedly embedded in the middle of the receiving groove, and the horizontal plate The top of the suspension bracket is rotatably connected to the top of the suspension bracket, and the top of the suspension bracket is rotatably connected to the top plate, and the outside of the connecting center shaft of the tire is fixedly sleeved with a second gear, and the bottom end of the hopper passes through the box body and is connected to one of the roller cavities.

[0006] Preferably, the connection center axis of the rotating shaft and the tire is located in the same vertical plane, and the bottom edge of the tire and the bottom edge of the universal wheel are located in the same horizontal plane.

[0007] Preferably, the first gear is meshed with the second gear, and the gear radius of the first gear is greater than the gear radius of the second gear.

[0008] Preferably, the screw rod is threadedly connected to the box body, and the suspension bracket is in an inverted "concave" shape.

[0009] Preferably, adjacent sides of the two roller cavities are provided with openings, and the two coating rollers are arranged to fit each other.

[0010] Preferably, the insertion rod is arranged between two paint rollers, and a plurality of bristles are fixedly embedded on the lower side of the brush plate.

[0011] A method for using a marking device for road and bridge construction:

[0012] a) In the non-marking state: rotate the screw upwards through the handle to drive the shaft upwards, so that the No. 1 gear is separated from the No. 2 gear, and the universal wheel can rotate freely. At this time, the rod is driven by the No. 1 spring to retract the brush plate upwards into the box;

[0013] b) In the drawing state: rotate the screw downward through the handle to drive the shaft downward, so that gear No. 1 and gear No. 2 engage. The two tires rotate at the same speed, and the box can only move in a straight line. At this time, the rod presses down the spring No. 1, and the brush plate extends from the bottom of the box to draw lines.

[0014] Compared with the prior art, the beneficial effects created by the present invention are as follows: the present invention creates a marking device for road and bridge construction, in which workers can automatically paint and draw lines by simply pushing the handrail, and the cam pushing method can make the painted mark a discontinuous dotted line, thereby avoiding the trouble of manual measurement section by section. When the bristles are stored in the receiving groove, they can drive the paint roller to rotate, and then the bristles can be automatically dipped in the material, which is convenient for repeated use and minimizes the process of manual participation. In conjunction with the liftable suspension frame, the two tires can be adjusted to synchronous rotation or differential rotation, which can not only assist workers in marking along a straight line, but also facilitate the movement of the marking device, greatly improving the efficiency of construction marking.

A spring 14 is sleeved between the top plate 13 and the cross plate 11 and on the outside of the plug rod 12. The bottom end of the plug rod 12 is fixedly connected to a brush plate 19. Vertical slots 9 are provided on the opposite side walls of the accommodating groove 20. A rotating shaft 7 is embedded between the two vertical slots 9. A cam 8 is fixedly sleeved on the middle outer side of the rotating shaft 7. Both ends of the rotating shaft 7 are fixedly connected to the No. 1 gear 10. The middle outer side of the rotating shaft 7 is also rotatably sleeved with a suspension bracket 6. The top of the suspension bracket 6 is rotatably connected to a screw rod 5. The top of the screw rod 5 is fixedly connected to a handle 4 through the box body 1. Both sides of the box body 1 are rotatably connected to tires 16. The outer side of the connection center axis of the tire 16 is fixedly sleeved with a No. 2 gear 15. The bottom end of the hopper 3 passes through the box body 1 and is communicated with one of the roller cavities 18.

[0021] Among them, the connection center axis of the rotating shaft 7 and the tire 16 is located in the same vertical plane, the connection center axis of the rotating shaft 7 and the tire 16 is arranged opposite to each other, and the bottom edge of the tire 16 and the bottom edge of the universal wheel 17 are located in the same horizontal plane, which can keep the box 1 stable.

[0022] Among them, the number one gear 10 is meshed with the number two gear 15, and the gear radius of the number one gear 10 is larger than the gear radius of the number two gear 15. The number one gear 10 and the number two gear 15 can move away from each other or mesh with each other, so that the tire 16 has two rotation states. When the two tires 16 can rotate differentially, the box 1 is easy to move. When the two tires 16 rotate synchronously, the box 1 can only move in a straight line, which plays the role of auxiliary marking.

[0023] Among them, the screw rod 5 is threadedly connected to the box body 1, and the suspension bracket 6 is an inverted "concave" shape. By rotating the screw rod 5, the screw rod 5 can be screwed into the threaded hole on the box body 1, and then the screw rod 5 can pull the suspension bracket 6 up or down.

A fluff layer for adhering paint is provided on the outside of the paint roller 24. Part of the circumference of the paint roller 24 can extend out of the opening to contact each other, so that the paint rollers 24 can contact each other, and the bottom of the paint roller 24 can continuously dip in paint to prevent the paint on the outer wall from drying up.

[0025] Among them, the insertion rod 12 is arranged between the two paint rollers 24, and a number of bristles are fixedly embedded on the lower side of the brush plate 19. When the end of the insertion rod 12 moves upward, it can drive the brush plate 19 to rise until the brush plate 19 can push the two paint rollers 24 apart, so that the No. 2 spring 22 is compressed, and then the bristles are squeezed by the two paint rollers 24. When the bristles rise, the paint roller 24 will also be driven to rotate, so that the paint on the paint roller 24 can adhere to the bristles.

[0026] Specifically, when the present invention is used, the handle 4 is rotated first, which can drive the screw rod 5 to rotate, and then the suspension frame 6 is pushed down, so that the rotating shaft 7 slides along the vertical slot 9 until the No. 1 gear 10 and the No. 2 gear 15 are meshed with each other, and the armrest 2 can be pushed to make the box body 1 move along a predetermined straight line trajectory. The tire 16 can roll along a straight line, which can drive the No. 2 gear 15 to rotate. The No. 2 gear 15 can mesh with the No. 1 gear 10 to rotate, so that the concave and convex edges of the cam 8 can squeeze the top plate 13 to rise and fall. When the end of the rod 12 moves down, it can push the brush plate 19 to fall until the bristles of the brush plate 19 can contact the ground. When the end of the rod 12 moves up, it can bring The movable brush plate 19 rises until the brush plate 19 can push open the two paint rollers 24, so that the No. 2 spring 22 is compressed, and then the bristles are squeezed by the two paint rollers 24, and when the bristles rise, the paint roller 24 is also driven to rotate, so that the paint on the paint roller 24 can adhere to the bristles, so as to prepare for the next painting. After the marking process is completed, the handle 4 is rotated in the opposite direction, and the suspension bracket 6 can pull the rotating shaft 7 to rise, and the No. 1 gear 10 and the No. 2 gear 15 are separated from each other. Under the elastic force of the No. 1 spring 14, the top plate 13 will be lifted, so that the brush plate 19 can be retracted into the accommodating groove 20, and the two tires 16 allow differential rotation, which can conveniently move the box 1.
