Description

Technical Field

[0001] This utility model relates to the technical field of road and bridge construction equipment, specifically a road and bridge marking device. Background Technology

[0002] In the process of road and bridge construction, marking is a fundamental and crucial step, mainly used to determine construction benchmarks, component installation positions, and surveying and setting out marks.

[0003] For example, a road and bridge marking device with authorization announcement number CN222744742U includes a trolley, a marking component, and a road surface cleaning component. The marking component and the road surface cleaning component are mounted on the trolley. Although the above document can achieve this, the nozzle and brush can clean the construction road surface to facilitate subsequent marking by the marking component. However, when applying the dots, the paint drips from the nozzle onto the dotting location. Due to the significant differences in the smoothness and absorbency of different road materials, such as smooth cement, rough asphalt, or gravel roadbed, and the fact that the nozzle height is fixed, the dotting points are prone to being too large, too small, blurry, or piling up, thus reducing the working effect of the dotting device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road and bridge marking device that solves the problem that, due to the significant differences in the smoothness and adsorption properties of different road surface materials, fixed-height nozzles are prone to producing markings that are too large, too small, blurry, or clumped together, thereby reducing the working effect of the marking device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge marking device, comprising a base plate, a bracket fixedly connected to the top of the base plate, a material box fixedly connected to the top of the bracket, a discharge pipe connected to the bottom of the material box, a nozzle connected to the bottom of the discharge pipe, and a movable structure provided inside the bracket; the movable structure comprises a hollow column, a threaded sleeve, a handle, a screw, and a cross plate; the hollow column is fixedly connected to the top of the inner wall of the bracket, a threaded sleeve is rotatably connected to the lower part of the inner wall of the hollow column via a bearing, a handle is fixedly connected to the outer wall of the threaded sleeve, a screw is threadedly connected to the inner wall of the threaded sleeve, a cross plate is fixedly connected to the bottom of the screw, and the cross plate is connected to the outer wall of the discharge pipe.

[0006] Preferably, a vertical block is fixedly connected to the lower side wall of the hollow column, a vertical rod is fixedly connected to the bottom of the vertical block, and the horizontal plate passes through the vertical rod and is movably connected to the vertical rod.

[0007] Preferably, a handrail is fixedly connected to the top of the base plate near the support, and casters are fixedly connected to the bottom of the base plate.

[0008] Preferably, a solenoid valve is fixedly connected to the lower outer wall of the feed pipe, and a switch is fixedly connected to the lower outer wall of the handrail.

[0009] Preferably, a housing is fixedly connected to the upper part of the inner wall of the bracket, and a storage battery is fixedly connected to the inner wall of the housing.

[0010] Preferably, the outer side of the horizontal plate is provided with a blocking structure; the blocking structure includes a connecting ear, a column, a connecting plate and a surrounding plate; the connecting ear is fixed to the top of the outer wall of the horizontal plate near the feed pipe, the column is inserted into the inner wall of the horizontal plate, the column is fixed to the outer wall of the connecting ear by bolts, the bottom of the column is fixed to the connecting plate, and the bottom of the connecting plate is fixed to the surrounding plate. Beneficial effects

[0011] This utility model provides a road and bridge marking device. It has the following advantages: This road and bridge marking device, through the cooperation of a hollow column, threaded sleeve, handle, screw, and cross plate, allows for precise adjustment of the nozzle distance from the ground according to the differences in the flatness and absorbency of road surface materials (such as smooth cement, rough asphalt, and gravel subgrade). This ensures consistency in marking accuracy and marking shape, solving the problem that due to significant differences in the flatness and absorbency of different road surface materials, a fixed-height nozzle can easily produce markings that are too large, too small, blurry, or clumped together, thus reducing the effectiveness of the marking device.

[0012] By coordinating the connecting ears, posts, connecting plates, and enclosures, the system prevents the falling paint from being blown away by the wind. This solves the problem that when applying paint to roads and bridges, the paint dripping from the nozzle is easily affected by crosswinds or gusts, causing the paint to deviate from the target application position.

Detailed Implementation

[0015] 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.

[0016] Due to the significant differences in the smoothness and absorbency of different road surface materials, nozzles at fixed heights are prone to producing markings that are too large, too small, blurry, or clumped together, thus reducing the effectiveness of the marking device.

[0017] In view of this, the present invention provides a road and bridge marking device. Through the cooperation between the hollow column, threaded sleeve, handle, screw and cross plate, the distance between the nozzle and the ground can be precisely adjusted according to the differences in the flatness and adsorption of the road surface material (such as smooth cement, rough asphalt, and crushed stone roadbed). This ensures the consistency of marking accuracy and marking shape, and solves the problem that due to the large differences in the flatness and adsorption of different road surface materials, the nozzle at a fixed height is prone to marking points that are too large, too small, blurry or piled up, thereby reducing the working effect of the marking device.

[0018] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0019] Example 1, by Figure 1-4 As can be seen, the road and bridge marking device in this case includes a base plate 1, a bracket 4 fixedly connected to the top of the base plate 1, a material box 5 fixedly connected to the top of the bracket 4, a feeding pipe 6 connected to the bottom of the material box 5, a nozzle 7 connected to the bottom of the feeding pipe 6, and a movable structure provided inside the bracket 4; the movable structure includes a hollow column 11, a threaded sleeve 12, a handle 13, a screw 14, and a horizontal plate 15; the hollow column 11 is fixedly connected to the top of the inner wall of the bracket 4, the threaded sleeve 12 is rotatably connected to the bottom of the inner wall of the hollow column 11 through a bearing, the handle 13 is fixedly connected to the outer wall of the threaded sleeve 12, the screw 14 is threadedly connected to the inner wall of the threaded sleeve 12, the horizontal plate 15 is fixedly connected to the bottom of the screw 14, and the horizontal plate 15 is connected to the outer wall of the feeding pipe 6; In the specific implementation process, it is worth noting that the feeding pipe 6 is made of PVC pipe, the nozzle 7 is made of brass, and the top of the material box 5 is connected to the feeding pipe. The staff opens the valve on the feeding pipe and pours the paint into the material box 5 through the feeding pipe. After that, the staff closes the valve on the feeding pipe. When marking, the paint inside the material box 5 enters the nozzle 7 through the feeding pipe 6 and finally falls through the nozzle 7 to the marking position on the road and bridge. The staff regularly cleans and maintains the entire device. When marking points on roads and bridges made of different materials, the operator turns the handle 13, which drives the threaded sleeve 12 to rotate. The threaded sleeve 12 drives the screw 14 to move, the screw 14 drives the horizontal plate 15 to move, and the horizontal plate 15 drives the feed pipe 6 to move, thereby moving the nozzle 7 to the designated position. After completion, the operator stops turning the handle 13. This allows for precise adjustment of the distance between the nozzle 7 and the ground according to the differences in the flatness and absorbency of the road surface material (such as smooth cement, rough asphalt, and gravel roadbed), ensuring the consistency of marking accuracy and marking shape. Furthermore, a vertical block 16 is fixedly connected to the lower side wall of the hollow column 11, and a vertical rod 17 is fixedly connected to the bottom of the vertical block 16. A horizontal plate 15 passes through the vertical rod 17 and is movably connected to the vertical rod 17. In the specific implementation process, it is worth noting that when the horizontal plate 15 moves, the horizontal plate 15 moves on the vertical rod 17 to limit the horizontal plate 15, so that the height adjustment of the nozzle 7 is more stable and precise. Furthermore, a handrail 2 is fixedly connected to the top of the base plate 1 near the support 4, and a caster wheel 3 is fixedly connected to the bottom of the base plate 1. In the specific implementation process, it is worth noting that when the staff holds the handrail 2 and pushes the handrail 2, the caster 3 rotates on the ground of the road and bridge, thereby moving the base plate 1 and then moving the nozzle 7, so that the staff can move the entire device to spray different positions. Furthermore, a solenoid valve 10 is fixedly connected to the lower outer wall of the feed pipe 6, and a switch 9 is fixedly connected to the lower outer wall of the handrail 2. In the specific implementation process, it is worth noting that the solenoid valve 10 is a two-position, two-way, direct-acting miniature solenoid valve made of brass, with the model example being 2W-025-08. The switch 9 is an IP65 waterproof and dustproof self-locking push-button switch, with the model example being XB2-BA31C. The solenoid valve 10 and the switch 9 are electrically connected. The solenoid valve 10 can be connected to the feed pipe 6 through a sealing flange and bolts. When dotting, the operator presses the switch 9, which energizes the solenoid valve 10, opening the solenoid valve 10 and allowing the paint to drip from the nozzle 7 onto the dotting position. After completion, the operator releases the switch 9, the solenoid valve 10 closes, and the downward flow stops, thus realizing the start and stop control of the dotting operation. Furthermore, a housing 22 is fixedly connected to the upper inner wall of the bracket 4, and a storage battery 8 is fixedly connected to the inner wall of the housing 22. In the specific implementation process, it is worth noting that the battery 8 is a 12V 10Ah lithium iron phosphate battery, model LP12100. The outer casing 22 can be connected to the bracket 4 by bolts, and the battery 8 can be connected to the outer casing 22 by bolts. The outer wall of the outer casing 22 has heat dissipation holes and wiring holes. The heat dissipation holes dissipate heat from the battery 8, and the wiring holes connect the battery 8 to the switch 9 and the solenoid valve 10. The battery 8 provides power to the solenoid valve 10.

[0020] Example 2, by Figure 1-4 It can be seen that a blocking structure is provided on the outside of the horizontal plate 15; the blocking structure includes a connecting ear 18, a column 19, a connecting plate 20 and a surrounding plate 21; the connecting ear 18 is fixed to the top of the outer wall of the horizontal plate 15 near the feed pipe 6, the column 19 is inserted into the inner wall of the horizontal plate 15, the column 19 is fixed to the outer wall of the connecting ear 18 by bolts, the bottom of the column 19 is fixed to the connecting plate 20, and the bottom of the connecting plate 20 is fixed to the surrounding plate 21. In the specific implementation process, it is worth noting that the enclosure 21 can be made of ABS plastic or thin stainless steel plate. During assembly, the worker moves the connecting plate 20 and inserts it into the bottom of the feed pipe 6. At the same time, the connecting plate 20 drives the column 19 to move and insert the column 19 into the horizontal plate 15. After completion, the worker rotates the corresponding bolts to fix the column 19 to the connecting ear 18, and then fixes the enclosure 21 to the nozzle 7. When the dotting action is performed, the enclosure 21 forms a closed constraint area below the nozzle 7, which can effectively resist the interference of wind or dust on the paint, forcibly constrain the marking shape, and prevent the wind from blowing away the falling paint.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
