Description
Technical Field
[0001] This utility model relates to the field of road construction technology, and in particular to an efficient curbstone renovation device. Background Technology
[0002] In current road renovation projects, the traditional method for treating old curbs involves removing them and then, before asphalt paving, bringing in newly purchased curbs and installing them manually and mechanically. This increases project costs and wastes stone resources. If old curbs are manually ground and repaired using angle grinders, the work is inefficient, labor-intensive, and produces poor quality. Therefore, there is an urgent need to research an efficient curb renovation device to provide a simpler and more effective process for reusing old curbs in road renovation projects. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient curbstone renovation device.

One end of the lateral adjustment bolt is fixed to the first T-shaped slider, and the other end passes through the first positioning rod and is connected to the first adjustment nut. The lateral adjustment bolt is connected to a first fixing nut that cooperates with the first adjustment nut to clamp the first positioning rod.
[0010] The height adjustment assembly includes a vertical adjustment bolt, a second adjustment nut, a second fixing nut, a second positioning rod, and a second T-shaped slider. The second positioning rod is fixed to the second mounting plate facing away from the opening direction of the second opening. The second mounting plates on both sides of the second opening have second adjustment slots arranged along the height direction of the vehicle body bracket. A second T-shaped slider that passes through the second adjustment slot and slides in cooperation with the second adjustment slot is fixed on the second fixing seat. One end of the vertical adjustment bolt is fixed to the second T-shaped slider, and the other end passes through the second positioning rod and is connected to the second adjustment nut. A second fixing nut that cooperates with the second adjustment nut to clamp the second positioning rod is connected to the vertical adjustment bolt.
[0011] Two angle adjustment components are symmetrically arranged along the longitudinal axis of the second mounting plate. Each angle adjustment component includes an angle adjustment bolt, a connecting lug, a swing rod, a third positioning rod, a third adjusting nut, and a third fixing nut. The third positioning rod is fixed on the vehicle body bracket above the second mounting plate. The connecting lug is fixed on the surface of the second mounting plate. One end of the swing rod is hinged to the connecting lug, and the other end is hinged to the angle adjustment bolt. The end of the angle adjustment bolt passes through the third positioning rod and is connected to the third adjusting nut. A third fixing nut, which cooperates with the third adjusting nut to clamp the third positioning rod, is connected to the angle adjustment bolt.
[0012] Two bamboo-shaped water spray pipes connected to an external water source are fixed on the vehicle body support. The outlet of one bamboo-shaped water spray pipe is set towards the grinding disc of the top surface grinder, and the outlet of the other bamboo-shaped water spray pipe is set towards the grinding disc of the vertical surface grinder.
[0013] The top surface grinder and the vertical surface grinder are fixed with splash guards that surround the grinding discs. The splash guards have notches that correspond to the water outlets of the bamboo-shaped water spray pipes.
[0014] This utility model has the following beneficial effects: The vehicle body support of this utility model maintains contact with the top surface and side surface of the curbstone through the top surface roller and the vertical surface roller respectively. The vehicle body support is pushed along the placement path of the curbstone on the road. At this time, the top surface grinder grinds the top surface of the curbstone, and the vertical surface grinder grinds the side surface of the curbstone simultaneously.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0027] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] like Figure 1 and Figure 2 As shown, this utility model provides a high-efficiency curbstone renovation device, including a vehicle body support 1, top surface rollers 6, vertical surface rollers 7, a top surface grinder 4, and a vertical surface grinder 5. The vehicle body support 1 has a first mounting plate 2 installed at the bottom and a second mounting plate 3 installed on one side and extending away from the first mounting plate 2. There are two top surface rollers 6, which are respectively installed at both ends of the first mounting plate 2 along the length direction of the vehicle body support 1. The top surface grinder 4 is installed in the middle of the first mounting plate 2 for grinding the top surface of the curbstone. There are two vertical surface rollers 7, which are respectively installed at both ends of the second mounting plate 3 along the length direction of the vehicle body support 1. The vertical surface grinder 5 is installed in the middle of the second mounting plate 3 for grinding the curbstone. The frame 1 maintains contact with the top and side surfaces of the curbstone via top rollers 6 and vertical rollers 7, respectively. This pushes the vehicle support 1 forward along the curbstone's path on the road, ensuring the vertical rollers 7 remain in contact with the curbstone's side surface without deviation. Simultaneously, an external power supply connects the device, and the top surface grinder 4 grinds the top surface of the curbstone, while the vertical surface grinder 5 grinds the side surface of the curbstone synchronously. This eliminates the need to remove the old curbstone, enabling its renovation and reuse. It reduces the amount of stone required and lowers construction costs. Compared to traditional manual grinding methods, this device significantly improves operational efficiency, reduces the labor intensity of construction workers, and ensures the quality of curbstone renovation.
[0029] In a further preferred embodiment, to avoid interference between the working spaces of the two grinding machines, the top surface grinding machine 4 and the vertical surface grinding machine 5 are staggered along the length of the vehicle body support 1. In this embodiment, the top surface grinding machine 4 is positioned in front and the vertical surface grinding machine 5 is positioned behind.
[0030] like Figures 3-5 As shown, to meet the grinding needs of curb stones of different sizes, a first fixed seat is fixed to the outer side of the motor body of the top surface grinder 4. The first fixed seat is connected to the first mounting plate 2 via a width adjustment component 8, and the first mounting plate 2 has a first opening 201 for the top surface grinder 4 to move along the width direction of the vehicle body support 1. A second fixed seat is fixed to the outer side of the motor body of the vertical surface grinder 5. The second fixed seat is connected to the second mounting plate 3 via a height adjustment component 9, and the second mounting plate 3 has a second opening 301 for the vertical surface grinder 5 to move along the height direction of the vehicle body support 1. The positions of the corresponding top surface grinder 4 and vertical surface grinder 5 are adjusted by the width adjustment component 8 and the height adjustment component 9, and the size of the grinding disc is adjusted in conjunction to adapt to curb stones of different heights / widths, so as to optimize the grinding range of the grinding disc and ensure grinding efficiency.
[0031] Specifically, such as Figure 5 As shown, the width adjustment component 8 in this solution includes a lateral adjustment bolt 803, a first adjustment nut 805, a first fixing nut 804, a first positioning rod 801, and a first T-shaped slider 802. The first positioning rod 801 is fixed to the second mounting plate facing away from the opening direction of the first opening 201. The first mounting plates 2 on both sides of the first opening 201 have first adjustment grooves 202 arranged along the width direction of the vehicle body bracket 1. The first fixing seat is fixed with a first T-shaped slider 802 that passes through the first adjustment groove 202 and slides in cooperation with the first adjustment groove 202. One end of the lateral adjustment bolt is fixed to the first T-shaped slider 802, and the other end passes through the first positioning rod 801 and is connected to the first adjustment nut 805. The lateral adjustment bolt is connected to a first fixing nut 804 that cooperates with the first adjustment nut 805 to clamp the first positioning rod 801.
[0032] like Figure 4As shown, the height adjustment assembly 9 includes a vertical adjustment bolt 903, a second adjustment nut 905, a second fixing nut 904, a second positioning rod 901, and a second T-shaped slider 902. The second positioning rod 901 is fixed to the second mounting plate facing away from the opening direction of the second opening 301. The second mounting plates 3 on both sides of the second opening 301 have second adjustment grooves 302 arranged along the height direction of the vehicle body bracket 1. The second fixing seat is fixed with a second T-shaped slider 902 that passes through the second adjustment groove 302 and slides in cooperation with the second adjustment groove 302. One end of the vertical adjustment bolt is fixed to the second T-shaped slider 902, and the other end passes through the second positioning rod 901 and is connected to the second adjustment nut 905. The vertical adjustment bolt is connected to a second fixing nut 904 that cooperates with the second adjustment nut 905 to clamp the second positioning rod 901. The width of the first mounting plate 2 is equivalent to the minimum width of the curbstone, and the width of the second mounting plate 3 is equivalent to the minimum height of the curbstone (the height of the curbstone protruding from the roadbed). By adjusting the length of the horizontal adjusting bolt extending from the first positioning rod 801, the relative distance between the top surface grinder 4 on the first fixed plate 401 and the first positioning rod 801 is adjusted. Then, a grinding disc is selected with the rotating shaft of the top surface grinder 4 as the center. Similarly, by adjusting the length of the vertical adjusting bolt extending from the second positioning rod 901, the relative distance between the vertical surface grinder 5 on the second fixed plate 501 and the second positioning rod 901 is adjusted. Then, a grinding disc is selected with the rotating shaft of the vertical surface grinder 5 as the center.
[0033] like Figure 6 As shown, the T-shaped slider in the height adjustment assembly 9 and width adjustment assembly 8 comprises a slider body 8021, a rotating shaft portion 8022 formed below the slider body 8021, and a mounting bolt 8023. The length of the slider body 8021 is greater than the width of the first adjustment groove 202 / second adjustment groove 302. The side of the slider body 8021 has a first internal thread portion that mates with the transverse adjustment bolt 803. The first fixing plate 401 / second fixing plate 501 has a through hole for the rotating shaft portion 8022 to pass through. The bottom of the rotating shaft portion 8022 has a second internal thread portion that mates with the mounting bolt 8023. When installing the T-shaped slider, the first internal thread portion 8022 is used to adjust the T-shaped slider. Taking the T-shaped slider 802 as an example, the first fixing plate 401 is placed below the first mounting plate 2, with the through hole aligned with the first adjusting groove 202. The rotating shaft 8022 of the first T-shaped slider 802 passes through the first adjusting groove 202 and the through hole in sequence and is threadedly connected to the mounting bolt 8023. The height of the rotating shaft 8022 is slightly greater than the sum of the thicknesses of the first fixing plate 401 and the first mounting plate 2, so that the assembled first fixing plate 401 can move laterally relative to the first mounting plate 2. The lateral adjusting bolt passes through the first positioning rod 801 and is fixedly connected to the slider body 8021, thus completing the installation of the first T-shaped slider 802 and the lateral adjusting bolt 803 on the first mounting plate 2.
[0034] like Figure 1 and Figure 2 As shown, in order to apply this device to the renovation of curb stones with large chamfers, one end of the second mounting plate 3 is rotatably connected to the vehicle body bracket 1 via a hinge 11, and the second mounting plate 3 is provided with an angle adjustment component 10 for adjusting the angle of the second mounting plate 3.
[0035] Specifically, there are two angle adjustment components 10, symmetrically arranged along the longitudinal axis of the second mounting plate 3. Each angle adjustment component 10 includes an angle adjustment bolt 1002, a connecting lug 1004, a swing rod 1003, a third positioning rod 1001, a third adjusting nut, and a third fixing nut. The third positioning rod 1001 is fixed to the vehicle body bracket 1 above the second mounting plate 3. The connecting lug 1004 is fixed to the surface of the second mounting plate 3. One end of the swing rod 1003 is hinged to the connecting lug 1004, and the other end is hinged to the angle adjustment bolt 1002. The end of the angle adjustment bolt 1002 passes through the third positioning rod 1001 and is connected to the third adjusting nut. A third fixing nut, which cooperates with the third adjusting nut to clamp the third positioning rod 1001, is connected to the angle adjustment bolt 1002. Figure 7 As shown in (a), in the initial state, the angle adjusting bolt 1002 is in the first position extending into the vehicle body bracket 1. At this time, the second mounting plate 3 forms a 90° perpendicular angle with the vehicle body bracket 1 / first mounting plate 2, as shown in (a). Figure 7 As shown in (b), the third adjusting nut is loosened to match the side of the curb with a certain slope angle. The device is placed on the curb. At this time, the top roller 6 contacts the top surface of the curb, and the vertical roller 7 contacts the side of the curb. Then, the angle adjusting bolt 1002 is pulled to the second position. At this time, the second mounting plate 3 and the vehicle body bracket 1 / first mounting plate 2 are inclined at an angle of 110°.
[0036] like Figure 2 and Figure 8 As shown, to cool and prevent dust from the grinding disc during grinding, two bamboo-joint water spray pipes 12 connected to an external water source are fixed on the vehicle body support 1. The outlet of one bamboo-joint water spray pipe 12 is set towards the grinding disc of the top surface grinding machine 4, and the outlet of the other bamboo-joint water spray pipe 12 is set towards the grinding disc of the vertical surface grinding machine 5. The external water source can be provided by installing a water supply tank on the engineering vehicle that moves with the construction, or by adding a temporary water tank to the vehicle body support 1.
[0037] The top surface grinder 4 and the vertical surface grinder 5 are fixed with splash guards 13 that surround the grinding disc. The splash guards 13 have notches 1301 that correspond to the water outlets of the bamboo-joint water spray pipe 12 to reduce the amount of water splashed to the outside of the device by the grinding of the grinding disc.
[0038] The above technical solution involves welding square tubing to form the vehicle body support 1, the first positioning rod 801, the second positioning rod 901, and the third positioning rod 1001. The first mounting plate 2, the second mounting plate 3, the first fixing plate 401, and the second fixing plate 501 are made of steel plates to ensure the strength and rigidity of the device, avoid the need for anti-rust paint, and extend the device's service life. A trolley handle 101 is welded to the top of the vehicle body support 1. During use, the top roller 6 and the vertical roller 7 maintain contact with the top and sides of the curbstone, respectively. By selecting different grinding discs, coarse grinding, fine grinding, and polishing effects are achieved, thereby removing scratches, corrosion, traffic marks, and surface contamination from the curbstone surface. This changes the previous method of removing and discarding old curbstones and installing newly purchased ones. By grinding and renovating the old curbstones, the amount of stone purchased is reduced, construction costs are lowered, and the goal of green and energy-saving construction is achieved.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
