[0025] This embodiment provides a walking line-marking device, see reference. Figures 1-5 As shown, the device includes two insert rods 1 and a line drawing assembly 2. A guide rope 11 is connected between the two insert rods 1. A powder hopper 21 is provided on the upper part of the line drawing assembly 2. A bracket 22 is connected to the bottom end of the powder hopper 21. A wire conduit 221 is installed at the bottom of the bracket 22. The guide rope 11 is inserted into the wire conduit 221. A first mounting block 222 is provided on the bottom side wall of the bracket 22. The side wall of the first mounting block 222 is connected to one end of a connecting rod 3. The other end of the connecting rod 3 is connected to a second mounting block 4. One side of the second mounting block 4 is rotatably connected to a traveling wheel 42 through a first rotating shaft 41. A powder outlet cavity 211 is connected to one side wall of the powder hopper 21. A powder outlet pipe 212 is connected to the bottom of the powder outlet cavity 211. The through hole of the powder outlet pipe 212 is set in a flat and elongated shape.

[0026] In the above embodiment, two insert rods 1 are used to insert into the two ends of the line, and a guide rope 11 is connected between the two insert rods 1. The direction of the guide rope 11 is a straight line formed by connecting the ends of the two insert rods 1. The guide rope 11 can be a cable. The guide rope 11 is in a straight state when connected between the two insert rods 1. A powder hopper 21 is provided on the upper part of the line drawing assembly 2. The powder hopper 21 can be used to load lime powder for line drawing. The powder hopper 21 can increase the amount of powder carried. A bracket 22 is connected to the bottom of the powder hopper 21, and a wire tube 221 is installed at the bottom of the bracket 22. The guide rope 11 is inserted in the wire tube 221, so that the wire tube 221 moves along the set direction of the guide rope 11 when it moves. The side wall of the first mounting block 222 is connected to one end of the connecting rod 3, and the other end of the connecting rod 3 is connected to the second mounting block 4. One side of the second mounting block 4 is rotatably connected to the traveling wheel 42 via the first rotating shaft 41. The traveling wheel 42 is used for the line marking assembly 2 to move on the ground. One side wall of the powder hopper 21 is connected to the powder outlet chamber 211, and the bottom of the powder outlet chamber 211 is connected to the powder outlet pipe 212. The through hole of the powder outlet pipe 212 is set in a flat and long strip shape, so that when the line marking powder flows out of the powder outlet pipe 212, it forms strip-shaped line markings on the ground. When in use, the construction personnel push the line marking assembly 2 along the guide rope 11 connected between the insert rods 1. The powder in the powder hopper 21 is sprinkled on the ground through the powder outlet pipe 212 to form line markings. Compared with manual line drawing, the powder is sprinkled more evenly. In addition, the straight guide rope 11 formed between the two insert rods 1 guides the line drawing assembly 2 to move and draw lines through the guide tube 221 on the line drawing assembly 2, thereby improving the accuracy of line drawing on the construction ground, reducing line deviation error, and improving line drawing efficiency.

[0027] In one embodiment of this application, see reference Figure 1 and Figure 3 As shown, a first motor 213 is installed on the other side wall of the powder hopper 21, and a stirring blade 214 is provided inside the powder hopper 21. The first motor 213 is connected to the stirring blade 214 in a transmission connection.

[0028] In the above embodiment, the powder used for drawing lines, such as lime powder, may clump, which will lead to uneven line drawing. The clumping of the powder will cause blockage of the powder outlet pipe 212. The powder hopper 21 is equipped with stirring blades 214, which stir the powder in the powder hopper 21, causing the powder to rub against each other and break down, thereby making the powder particles finer. This is beneficial to improving the smoothness of the powder discharge from the powder outlet pipe 212 and improving the line drawing efficiency. On the other hand, if it is necessary to change the color of the line drawing powder, dyeing pigment can be added to the powder hopper 21 and mixed with the powder in the powder hopper 21.

[0029] In one embodiment of this application, see [reference] Figure 2As shown, the other side of the second mounting block 4 is connected to one end of the support rod 431 via a damping pivot 43.

[0030] In the above embodiment, when the line marking assembly 2 is placed on the ground, the support rod 431 rotates around the damping shaft 43 so that the other end of the support rod 431 contacts the ground or is inserted into the ground, so that the line marking assembly 2 remains stationary and prevents the line marking assembly 2 from moving on its own when placed alone, thus avoiding contact with construction personnel and equipment.

[0031] In one embodiment of this application, see reference Figure 5 As shown, a liquid storage tank 223 is provided at the bottom of the bracket 22, and a nozzle 224 is installed below the liquid storage tank 223.

[0032] In the above embodiment, the liquid tank 223 is filled with liquid dye, which is sprayed from the nozzle 224 below the liquid tank 223 for marking lines on the ground. Powder is easily affected by the weather, such as windy weather, and the powder markings are easily blown away or washed away, making it suitable for short-term and temporary use. Liquid dyes, such as spray paint, have strong adhesion and are suitable for long-term marking. The marking material can be selected according to actual needs, which helps to improve the adaptability of the marking device.

[0033] In one embodiment of this application, see reference Figure 4 As shown, the first mounting block 222 has a fastening bolt 5 connected to its side wall, and one end of the connecting rod 3 is sleeved with the fastening bolt 5.

[0034] In the above embodiment, under normal conditions, one end of the connecting rod 3 is sleeved with the fastening bolt 5. The fastening bolt 5 is screwed into the first mounting block 222 to clamp one end of the connecting rod 3, so that the support angle of the connecting rod 3 on the bracket 22 remains unchanged. When the fastening nut is loosened, the one end of the connecting rod 3 sleeved with the fastening bolt 5 can be deflected around the fastening bolt 5 to adjust the support angle of the connecting rod 3 on the bracket 22. By changing the support angle of the connecting rod 3 on the bracket 22, the support height of the connecting rod 3 on the bracket in the vertical direction can be changed, thereby changing the body height and the volume occupied in the space of the marking assembly 2, which facilitates the storage and transportation of the marking assembly 2.

[0035] In one embodiment of this application, see reference Figure 2 As shown, a cover plate 6 is provided on the upper part of the powder hopper 21.

[0036] In the above embodiment, a cover plate 6 is provided on the upper part of the powder hopper 21. On the one hand, it prevents the powder in the powder hopper 21 from flying to the outside, causing powder waste and air pollution. On the other hand, the cover plate 6 seals the powder hopper 21 to prevent external factors such as rainwater from entering the powder hopper 21 and causing the powder in the powder hopper 21 to become damp and clump together.

[0037] In one embodiment of this application, see reference Figure 3 As shown, a plate 7 is inserted into the side wall of the powder outlet chamber 211.

[0038] In the above embodiment, by inserting and removing the insert plate 7, the length of the insert plate 7 blocking the powder outlet of the powder outlet tube 212 is controlled, and the cross-sectional area of ​​the powder outlet of the powder outlet tube 212 is adjusted to adjust the width of the marking line.

[0039] In one embodiment of this application, a displacement sensor is mounted on the upper part of the second mounting block 4.

[0040] In the above embodiments, the displacement sensor is used to monitor the position and movement trajectory of the marking component, which facilitates the supervisor to backtest and verify the marking position, reduce marking errors, and improve the accuracy of the construction position. Optionally, the displacement sensor can use laser or satellite positioning system to record the displacement changes of the moving parts.

[0041] In actual use of this application: the insertion point of the insertion rod 1 is determined by a positioning surveying instrument. The direction of the guide rope 11 is the straight line formed by connecting the endpoints of the two insertion rods 1. The guide rope 11 is in a taut state when connected between the two insertion rods 1. The powder hopper 21 can be used to load lime powder for marking lines. The powder hopper 21 can increase the powder carrying capacity. The bottom of the powder hopper 21 is connected to a bracket 22, and a guide tube 221 is installed at the bottom of the bracket 22. The guide rope 11 is inserted into the guide tube 221, so that the guide tube 221 moves along the guide rope. The first mounting block 222 moves in the set direction. The side wall of the first mounting block 222 is connected to one end of the connecting rod 3. The other end of the connecting rod 3 is connected to the second mounting block 4. One side of the second mounting block 4 is rotatably connected to the walking wheel 42 through the first rotating shaft 41. The walking wheel 42 is used for the line drawing assembly to move on the ground. One side wall of the powder hopper 21 is connected to the powder outlet chamber 211. The bottom of the powder outlet chamber 211 is connected to the powder outlet pipe 212. The through hole of the powder outlet pipe 212 is set in a flat and long strip shape, so that when the line drawing powder flows out from the powder outlet pipe 212, it forms a strip-shaped line drawing mark on the ground.

[0042] When in use, a single person can simply push the line drawing component 2 along the set direction of the guide rope 11 to complete the line drawing work, which helps to improve the efficiency of line drawing.
