Description

Technical Field

[0001] This application relates to the field of road construction technology, and in particular to a road marking auxiliary device. Background Technology

[0002] Lime marking is a common temporary marking method used in highway construction. For example, lime lines can be used to mark key construction locations such as roadbed boundaries, pipeline trench locations, and pile center points, facilitating precise subsequent mechanical or manual construction. During construction, it is sometimes also necessary to demarcate temporary lanes, safety zones, or hazard warning strips.

[0003] In the process of highway construction, the traditional way of marking lines is for workers to hold shovels filled with lime and shake them along a predetermined route to create the required lines on the ground. However, this method is not only inefficient but also labor-intensive. Therefore, this method has gradually been replaced by a trolley with a lime hopper. As the trolley moves, the lime in the hopper automatically drips into the ground. When the trolley completes the path to be marked, the lime forms the desired line on the ground. While this marking device improves efficiency and reduces the workload for workers, the distance between the hopper's outlet and the ground is usually relatively small (common marking devices have an outlet distance of 5-15cm to shorten the lime spray path, reduce wind and airflow interference on the material's trajectory, and prevent blurred or broken lines). To ensure marking quality, workers need to constantly look down to check if the marked line deviates from the designed route while pushing the trolley. Given the complex environment of construction sites, workers may have accidents due to not observing the road ahead in time. Therefore, there is an urgent need for a marking auxiliary device that allows workers to easily observe the road ahead during the marking process. Utility Model Content

[0004] This application provides a road marking auxiliary device that allows workers to easily observe the road conditions ahead during the marking process, thus preventing accidents caused by a lack of visibility.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A road marking auxiliary device includes a frame, with wheels mounted at the front end of the frame and handlebars mounted at the rear end of the frame. A ash bucket is mounted in the middle of the frame, and an ash discharge pipe is provided at the lower end of the ash bucket. A control valve is mounted on the ash discharge pipe, and the control valve is used to control the opening and closing of the channel inside the ash discharge pipe.

[0007] The wheel is provided with an inclined first reflector on the side near the handlebar. The first reflector is fixedly connected to the frame by a first bracket, and the upper end of the first reflector is biased towards the front end of the frame. The first reflector is located between the wheel and the ash discharge pipe.

[0008] A second rearview mirror, parallel to the first rearview mirror, is mounted on the upper side of the vehicle frame opposite to the first rearview mirror via a second bracket, and the sides of the first and second rearview mirrors that are close to each other are their mirror sides.

[0009] A main observation mirror is mounted on the front end of the upper side of the vehicle frame via a third bracket, and the mirror surface of the main observation mirror faces the second reflector.

[0010] Furthermore, the outer side of the wheel is provided with a mudguard, and the mudguard is fixedly connected to the vehicle frame.

[0011] Furthermore, a support shaft is fixedly provided on one opposite side of the gray bucket along the width direction of the vehicle frame, and both support shafts are fixedly connected to the vehicle frame. The upper port of the gray bucket is not higher than the upper edge of the second reflector.

[0012] Furthermore, the plane of the main observation mirror is perpendicular to the horizontal plane, and the upper edge of the main observation mirror is higher than the upper edge of the second reflector, while the lower edge of the main observation mirror is directly opposite the center of the second reflector.

[0013] Furthermore, the control valve includes a slanted sleeve, the inner diameter of which is equal to the inner diameter of the ash discharge pipe. The slanted sleeve and the ash discharge pipe are welded together, and their internal spaces are connected. A cylindrical plug is inserted into the slanted sleeve, the outer diameter of which is equal to the inner diameter of the slanted sleeve. A limiting ring is fixed to the outer side of the upper end of the plug. When the lower side of the limiting ring contacts the upper end of the slanted sleeve, the position of the plug inside the slanted sleeve can precisely block the channel inside the ash discharge pipe.

[0014] Furthermore, the upper end of the plug is connected to a control unit that allows workers to remotely control the position of the plug within the inclined sleeve.

[0015] Furthermore, the control unit includes a force transmission rod, the lower end of which is fixedly connected to the upper end of the plug and the two are coaxially arranged. Two hanging rings are movably sleeved on the rod body of the force transmission rod. The two hanging rings are fixedly connected to a crossbeam between the two handlebars through a hanging rod. A transverse grip is fixedly provided at the upper end of the force transmission rod.

[0016] Furthermore, a through hole is provided on the upper side of the rod body near the handle end of the force transmission rod, and the distance between the through hole and the handle is equal to the distance when the lower end of the plug moves upward to open the internal channel of the ash discharge pipe.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] This application features a first reflector between the wheel and the ash discharge pipe, with a second reflector positioned above it. A main observation mirror, with its mirror side facing the second reflector, is located at the front of the frame. This allows the image of the road surface to be transmitted through the first reflector to the second reflector and then reflected back to the main observation mirror when the worker pushes the equipment to mark lines on the road. Because the main observation mirror is located at the front of the frame, the worker can observe the road conditions ahead while simultaneously seeing the white ash lines below the ash discharge pipe displayed in real-time on the main observation mirror. This allows the worker to not only observe the line marking process in real-time but also maintain a view of the road ahead, effectively preventing accidents due to limited visibility during the marking process.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0025] like Figures 1-3 As shown, this application discloses a road marking auxiliary device, which includes a frame 1, a wheel 16 installed at the front end of the frame 1, a handlebar 2 installed at the rear end of the frame 1, a ash bucket 3 installed in the middle of the frame 1, an ash discharge pipe 4 provided at the lower end of the ash bucket 3, and a control valve 5 installed on the ash discharge pipe 4. The control valve 5 is used to control the opening and closing of the channel inside the ash discharge pipe 4.

[0026] A tilted first reflector 6 is provided on the side of the wheel 16 near the handlebar 2. The first reflector 6 is fixedly connected to the frame 1 through the first bracket 7, and the upper end of the first reflector 6 is biased towards the front end of the frame 1. The first reflector 6 is located between the wheel 16 and the ash discharge pipe 4.

[0027] A second rearview mirror 9, which is parallel to the first rearview mirror 6, is installed on the upper side of the frame 1 at a position opposite to the first rearview mirror 6 via a second bracket 8, and the sides of the first rearview mirror 6 and the second rearview mirror 9 that are close to each other are their mirror sides.

[0028] A main observation mirror 11 is mounted on the front end of the upper side of the frame 1 via a third bracket 10, and the mirror surface of the main observation mirror 11 faces the second reflector 9.

[0029] In the above embodiments, the main structure composed of the frame 1 and the wheels 16 is similar to a unicycle. The ash bucket 3 installed in the middle of the frame 1 can be used to store lime for marking lines. The ash discharge pipe 4 below the ash bucket 3 can guide the lime flowing out of the ash bucket 3 to mark the required lines on the ground. The control valve 5 on the ash pipe allows workers to control the amount of lime discharged at any time as needed.

[0030] This application provides an inclined first reflector 6 on the side of the wheel 16 near the handlebar 2. The upper end of the inclined first reflector 6 is biased towards the front end of the frame 1, and a second reflector 9 is provided directly above the first reflector 6 and parallel to it. The mirror surfaces of the first reflector 6 and the second reflector 9 are located on their adjacent sides. In addition, the height of the first reflector 6 is similar to that of the ash outlet pipe 4. In this way, during the marking process, the first reflector 6 can capture the image of the white ash flowing out of the ash outlet pipe 4 marking the ground and reflect this image to the second reflector 9 through its mirror surface. The second reflector 9 is located on the upper side of the frame 1 and its mirror surface faces the main observation mirror 11 set at the front end of the frame 1. Therefore, the second reflector 9 will further transmit the marking image transmitted from the first reflector 6 to the main observation mirror 11. When the worker pushes the entire device, he does not need to make any extra movements while observing the road ahead. The front part of the frame 1 will inevitably enter the worker's field of vision. The mirror of the main observation mirror 11 of this application shows the real-time situation of the white lime discharged from the ash outlet pipe 4 drawing the markings. In this way, the worker can not only observe the marking process in real time during the marking process on the highway so that problems can be corrected in time, but also keep an eye on the road ahead. This effectively avoids accidents due to lack of vision during the marking process (for example, if there are obstacles such as construction machinery on the road in the marking area, the worker may hit the obstacle if he fails to observe it in time, or when marking the roadbed boundary, there may be a ditch on one side of the roadbed, and if the worker fails to observe the road ahead in time, he may fall).

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, a mudguard 12 is provided on the outer side of the wheel 16, and the mudguard 12 is fixedly connected to the frame 1.

[0032] In the above embodiments, the mudguard 12 provided on the outside of the wheel 16 can not only provide a certain degree of protection for the wheel 16, but also effectively prevent the mud and water splashed up by the wheel 16 during the rotation of rainy weather from contaminating the frame 1, the first rearview mirror 6 and other components.

[0033] Furthermore, such as Figure 1 and Figure 3 As shown, a support shaft 13 is fixedly provided on one opposite side of the gray bucket 3 along the width direction of the frame 1. Both support shafts 13 are fixedly connected to the frame 1. The upper port of the gray bucket 3 is not higher than the upper edge of the second reflector 9.

[0034] In the above embodiments, the ash bucket 3 can obtain stable support from the frame 1 through the support shaft 13. The upper end of the ash bucket 3 is located no higher than the upper edge of the second reflector 9, so that the ash bucket 3 can prevent the ash bucket 3 from blocking part of the image when the worker observes the image on the main observation mirror 11.

[0035] Furthermore, such as Figure 2 As shown, the plane where the main observation mirror 11 is located is perpendicular to the horizontal plane, and the upper edge of the main observation mirror 11 is higher than the upper edge of the second reflector 9, while the lower edge of the main observation mirror 11 is directly opposite the center of the second reflector 9.

[0036] In the above embodiments, the main observation mirror 11 of this application is set in the manner described above, which can ensure that a part of its mirror surface overlaps with the second reflector 9 to a certain extent, while another part is located above the second reflector 9. In this way, the second reflector 9 can not only reflect the image smoothly onto the main observation mirror 11, but the main observation mirror 11 can also smoothly transmit these effects to the eyes of the worker who is driving the entire equipment to move through its part which is higher than the second reflector 9.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, the control valve 5 includes a slanted sleeve 51, the inner diameter of which is equal to the inner diameter of the ash discharge pipe 4. The slanted sleeve 51 and the ash discharge pipe 4 are welded together and their internal spaces are connected. A cylindrical plug 52 is inserted into the slanted sleeve 51, the outer diameter of which is equal to the inner diameter of the slanted sleeve 51. A limiting ring 53 is fixed on the outer side of the upper end of the plug 52. When the lower side of the limiting ring 53 contacts the upper end of the slanted sleeve 51, the position of the plug 52 inside the slanted sleeve 51 can just block the channel inside the ash discharge pipe 4.

[0038] In the above embodiments, the internal spaces of the inclined sleeve 51 and the ash discharge pipe 4 are connected. The upper end of the inclined sleeve 51 is inclined towards the handlebar 2. The plug 52 inserted into the inclined sleeve 51 can block the channel in the ash discharge pipe 4 under normal conditions, thereby preventing the lime in the ash bucket 3 from leaking out when not in use. The limiting ring 53 at the upper end of the plug 52 can prevent the plug 52 from sliding out of the inclined sleeve 51 under the action of gravity. Since the plug 52 is movably inserted into the inclined sleeve 51, when the worker needs to mark lines, the plug 52 can be pulled upwards out of the inclined sleeve 51, which is simple and convenient to operate.

[0039] Furthermore, such as Figures 1-3 As shown, the upper end of the plug 52 is connected to a control unit 14, which allows workers to remotely control the position of the plug 52 inside the inclined sleeve 51.

[0040] In the above embodiments, when a worker needs to use lime to mark lines, if he first squats down to pull out the plug 52 from the inclined sleeve 51, and then stands up and pushes the handle 2 to move the entire device, this process will obviously increase the amount of lime wasted at the starting point because the distance between the worker and the plug 52 is relatively large. Therefore, this application adds a control unit 14 to the plug 52, which allows the worker to remotely control the position of the plug 52 inside the inclined sleeve 51 from near the handle. This reduces the interval time between the opening of the ash outlet pipe 4 and the moment the entire device moves, thereby effectively reducing the amount of lime wasted at the starting point of the marking.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the control unit 14 includes a force transmission rod 141. The lower end of the force transmission rod 141 is fixedly connected to the upper end of the plug 52 and the two are coaxially arranged. Two hanging rings 142 are movably sleeved on the rod body of the force transmission rod 141. The two hanging rings 142 are fixedly connected to a hanging rod 143 and a crossbeam 144 between the two handlebars 2. A horizontal grip 145 is fixedly provided at the upper end of the force transmission rod 141.

[0042] In the above embodiments, the lower end of the force transmission rod 141 is connected to the upper end of the plug 52. The upper end of the force transmission rod 141 extends obliquely upwards from the gap at the rear end of the frame 1 to below the handlebar 2. The hanging ring 142, which is fixedly installed on the handlebar 2, is movably sleeved on the force transmission rod 141. When the worker needs to open the ash outlet pipe 4, he can change the position of the plug 52 in the inclined sleeve 51 by pulling the force transmission rod 141 upwards without squatting down. When the worker needs to close the ash outlet pipe 4, he can also directly drive the plug 52 to re-seal the ash outlet pipe 4 in the inclined sleeve 51 without squatting down. Since the time for the worker to squat and stand up is reduced, the amount of lime wasted can be effectively reduced accordingly.

[0043] Furthermore, such as Figure 3 As shown, a through hole 15 is provided on the upper side of the rod body near the handle 145 on the force transmission rod 141. The distance between the through hole 15 and the handle 145 is equal to the distance when the lower end of the plug 52 moves upward to open the internal channel of the ash pipe 4.

[0044] In the above embodiments, the distance between the through hole 15 on the force transmission rod 141 and the handle 145 is equal to the distance the plug 52 moves upward to open the internal channel of the ash discharge pipe 4. In this way, when the worker pulls the force transmission rod 141 upward through the handle 145, when the force transmission rod 141 opens the ash discharge pipe 4 with the plug 52, the through hole 15 on the force transmission rod 141 just extends out of the upper lifting ring 142. At this time, the worker can use a limiting plug such as a pin to insert into the through hole 15 to limit the position of the force transmission rod 141 and the plug 52, so as to ensure that the plug 52 will not fall back and block the ash discharge pipe 4 during the subsequent movement of the entire device, thus affecting the continuity of the marking.

[0045] The implementation principle of this embodiment is as follows: Before use, the worker needs to add the lime for marking into the lime bucket 3, and then confirm the location and route of the line to be marked with the technician. In specific use, the worker stands between the two handlebars 2 and pulls the transmission rod 141 upward through the handle 145. When the through hole 15 on the transmission rod 141 is exposed from the top of the uppermost lifting ring 142, the worker quickly inserts the pre-prepared pin into the through hole 15 on the transmission rod 141. At this time, the plug 52 connected to the lower end of the transmission rod 141 can open the channel of the lime outlet pipe 4, and the lime in the lime bucket 3 can flow out quickly from the lime outlet pipe 4. Then, the worker holds the two handlebars 2 with both hands and drives the entire equipment to move along the designed route. The trajectory of the lime discharged from the lime outlet pipe 4 in this process can form the required line on the road surface. During the movement of the entire device, the first reflector 6 can reflect the real-time situation of the white lime marking at the ash outlet pipe to the second reflector 9. Part of the second reflector 9 faces the main observation mirror 11. Therefore, the second reflector 9 will further reflect the image received from the first reflector 6 to the main observation mirror 11. Since the main observation mirror 11 is located at the front of the frame 1, the worker can see the white lime marking below the ash outlet pipe 4 in real time on the main observation mirror 11 while observing the road conditions in front of the frame 1. This not only ensures the safety of the worker when marking the lines, but also allows the worker to quickly adjust the direction of the wheels 16 to correct the marking line shape when the marking trajectory deviates.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
