Description

Technical Field

[0001] This utility model relates to the technical field of curbstone asphalt coating equipment, specifically to a positioning device for rapid coating of diluted asphalt onto curbstones. Background Technology

[0002] With the continuous acceleration of urban infrastructure renovation and construction, the requirements for green construction are becoming higher. As a key link in urban development, road engineering has attracted much attention for its engineering quality and green construction. As an important component of road engineering, curb stones are widely used between the median strips of urban motor vehicle lanes and non-motor vehicle lanes, and between pedestrian walkways and non-motor vehicle lanes. They not only protect the road edges and maintain the integrity of the road structure, but also play an important role in traffic safety, while having a significant impact on the overall aesthetics of the road.

[0003] The construction process for asphalt pavement requires that, before laying asphalt concrete, a suitable amount of diluted asphalt must be applied to the junction between the curb and the asphalt pavement to enhance the adhesion between them. This is crucial for ensuring the overall quality and durability of the road. Currently, the common method for applying diluted asphalt to curbs is manual application. This involves first marking a standard line based on the exposed height of the curb, and then applying the asphalt according to that line. This traditional method has many drawbacks. Firstly, it is inefficient, requiring at least three workers: two for marking the line and one for applying the asphalt. Secondly, it is difficult to precisely control the application height during manual application, causing the diluted asphalt to fluctuate around the standard line. If it exceeds the standard line, it contaminates the exposed curb and affects its overall appearance. If it falls below the standard line, the asphalt will not adhere tightly to the curb, leading to water seepage and damage. Consequently, the appearance and construction quality of the project cannot be guaranteed, increasing repair costs and causing urban environmental pollution. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figure 1-5As shown, this utility model embodiment provides a positioning device for quickly applying diluted asphalt to curb stones, including a main frame 1, a fixed pole 2 on one side of the main frame 1, a height positioning pole 3 that can be extended vertically at the lower end of the fixed pole 2, a painting ruler 4 horizontally placed on the side of the height positioning pole 3 facing the curb stone 20, and a movable pole 5 that can be adjusted left and right on the other side of the main frame 1. The fixed pole 2 and the movable pole 5 are respectively clamped on both sides of the upper end of the curb stone 20.

[0024] The movable upright 5 is provided with a width positioning rod 6 at its upper end. The main frame 1 is provided with a slot at the position corresponding to the movable upright 5. The width positioning rod 6 is inserted into the slot of the main frame 1. The lower end of the fixed upright 2 is also provided with a slot. The height positioning rod 3 is inserted into the slot of the fixed upright 2. The width positioning rod 5 and the height positioning rod 3 are fixedly connected to the main frame 1 and the fixed upright 2 respectively by quick-connect pins.

[0025] The main frame 1 and the upright rod 2 are provided with positioning holes at the corresponding slots. The width positioning rod 6 is provided with several insertion holes 7 along its horizontal direction and the height positioning rod 3 is provided with several insertion holes 7 along its vertical direction. The quick-install pin passes through the positioning holes and insertion holes 7 at the same time.

[0026] The main frame 1 includes a horizontal bar 8 and vertical bars 9 set at both ends of the horizontal bar 8. The horizontal bar 8 and the vertical bars 9 cooperate to form an I-shaped frame. The fixed pole 2 is set at one end of the vertical bars 9 on both sides. The slot on the main frame 1 is set at the other end of the vertical bar 9. The width positioning rod 6 is inserted into the slot of the vertical bar 9. The positioning through hole on the main frame 1 is set at the end of the vertical bar 9. The painting straightedge 4 is fixed on the height positioning rods 3 on both sides.

[0027] The quick-installation pin includes a pin 10 that passes through both the positioning through hole and the insertion hole 7. One end of the pin 10 is provided with a rod head 11. A retaining spring 12 is sleeved on the end of the pin 10 with the rod head 11. One end of the retaining spring 12 abuts against the rod head 11, and the other end of the retaining spring 12 abuts against the side wall of the stationary rod 2 and the longitudinal rod 9. A limiting protrusion 13 is provided on the side wall of the pin 10 away from its rod head 11. Both the positioning through hole and the insertion hole 7 are provided with clearance grooves 14. The clearance grooves 14 at the same hole position are interconnected to form a movable groove that facilitates the passage of the limiting protrusion 13. The clearance grooves 14 are interconnected with their respective positioning through holes and insertion holes 7.

[0028] The upright pole 2 and the longitudinal pole 9 are provided with a slot 15 on the side wall away from the pole head 11, which is adapted to the limiting protrusion 13. The slot 15 is connected to the positioning through hole and is located on the side opposite to the position of the clearance slot 14.

[0029] During assembly, the positions of the movable upright 5 and the height positioning rod 3 are adjusted according to the size and specifications of the curbstone 20 and the position of the asphalt standard line. The width positioning rod 6 at the end of the movable upright 5 slides along the slot of the longitudinal rod 9. The distance between the movable upright 5 and the fixed upright 2 is selected based on the width of the curbstone 20. At this time, the corresponding insertion hole 7 on the width positioning rod 6 connects with the positioning through hole on the longitudinal rod 9. Then, the limiting protrusion 13 at the end of the pin 10 is aligned with the clearance groove 14 on the positioning insertion hole and inserted. At this point, the entire pin 10... The pin 10 can then pass through the positioning hole and insertion hole 7 to the longitudinal rod 9 and the width positioning rod 6. When the limiting protrusion 13 at the end of the pin 10 extends out on one side of the longitudinal rod 9, the rod head 11 cooperates with the side wall of the longitudinal rod 9 to press the clamping spring 12. Then, rotate the pin 10 and align the limiting protrusion 13 at its end with the slot 15 on the side wall of the longitudinal rod 9. Release the pin 10. Under the action of the restoring elastic force of the clamping spring 12, the limiting protrusion 13 can be locked in the slot 15. At this time, the pin 10 cannot be pulled out, and the position of the moving upright 5 is also fixed.

[0030] Similarly, based on the position of the asphalt standard line, slide the height positioning rod 3 along the slot at the lower end of the upright pole 2. After the position is selected, the insertion hole 7 of the height positioning rod 3 is connected to the positioning insertion hole on the upright pole 2. Insert the pin 10 in the same way as described above. After insertion, rotate the pin 10 so that the limiting protrusion 13 at its end clamps into the groove 15 on the side wall of the upright pole 2. This completes the fixing of the height positioning rod 3.

[0031] A first mounting base 21 is provided at the lower end of the middle of the longitudinal bar 9 and the cross bar 8. An upper guide wheel 16 is provided on the first mounting base 21, and the upper guide wheel 16 slides along the upper end surface of the curb stone 20.

[0032] The fixed pole 2 and the movable pole 5 are provided with a second mounting base 17 at their lower ends on opposite sides. The second mounting base 17 is provided with a side guide wheel 18. The side guide wheel 18 slides along the two sides of the curbstone 20. The paint brush 4 is located below the side guide wheel 18. The end face of the side guide wheel 18 on the fixed pole 2 facing the movable pole 2 is flush with the end face of the paint brush 4 away from the height positioning rod 3.

[0033] A lifting handle 19 is provided above the vertical bars 9 on both sides.

[0034] The working principle of this utility model is as follows: After adjusting the positions of the movable pole 5 and the height positioning pole 3 according to the positions of the curbstone 20 and the asphalt standard line, the entire device is lowered along the upper end of the curbstone 20. The upper guide wheels 16 on the horizontal bar 8 and the vertical bar 9 are attached to the upper surface of the curbstone 20. At this time, the side guide wheels 18 on the movable pole 5 and the fixed pole 2, as well as the painting ruler 4, are attached to both sides of the curbstone 20. Among them, the side guide wheels 18 on the fixed pole 2 and the painting ruler 4 are located on the side of the curbstone 20 that contacts the road surface. At this time, the curbstone sidewall located at the lower end of the painting ruler 4 is the part that needs to be coated with asphalt. The worker can then apply diluted asphalt to the curbstone. On the side wall, because the brushing ruler 4 has a certain width, it will play a certain protective role on the side wall of the curbstone 20, thus preventing the asphalt from being brushed above the standard line. After brushing a local area, push the device along the curbstone. The upper guide wheel 16 and the side guide wheel 18 will slide along the top and side wall of the curbstone 20, which makes the movement of the device on the curbstone 20 smoother. Move the brushing ruler 4 on the device to the unpainted area and brush the asphalt again. Repeat this process, and the workers can quickly complete the work. The whole process does not require measurement or line marking, which ensures the neatness of the painted surface and greatly improves work efficiency.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
