Description

Technical Field

[0001] This utility model belongs to the field of road surface crack repair technology, specifically relating to a compaction tool for road surface crack repair. Background Technology

[0002] Road surface cracking is mainly caused by a combination of factors, including material aging and brittleness, thermal expansion and contraction due to temperature changes, overloaded vehicles, substandard construction (such as insufficient compaction or defective joints), frost heave damage caused by moisture infiltration, and unstable foundation. These factors weaken the structural strength, causing stress accumulation to exceed the material's bearing capacity, ultimately leading to cracks.

[0003] Currently, there are two common types of road surface cracks. One type is dense cracks and potholes. These cracks require the entire damaged road surface to be removed, then re-grouted, leveled, and compacted. The second type is a small number of expansive cracks. There are two ways to repair a small number of expansive cracks. One is to use equipment such as a crack filling machine to directly inject repair grout into the crack. This repair method does not require compaction. You only need to smooth out the grout that overflows from the crack. The grout will automatically cool and solidify, completing the filling of the crack. The second method is to use crack sealing tape. The crack sealing tape is directly applied along the crack to complete the repair.

[0004] When using crack sealing tape, it needs to be pressed firmly onto the road surface to ensure a secure bond and prevent it from falling off later. Currently, after the crack sealing tape is applied, it is generally compacted using a hand-push single steel wheel. However, current hand-push single steel wheels are quite heavy and are generally used as a substitute for road rollers for compacting the road surface. They are inconvenient to transport and carry, and also inconvenient to steer flexibly. Crack sealing tape is generally narrow and does not require much pressure, so using small wheels for compaction is more suitable. This allows for flexible steer and compaction with the crack sealing tape. However, the pressure that small wheels can provide is relatively limited. Therefore, we propose a compaction tool for road crack repair to solve the above problems. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a compaction tool for road crack repair. Current hand-push single steel wheels are relatively heavy and are generally used to replace road rollers for compacting road surfaces. They are inconvenient to transport and carry, and also inconvenient to maneuver. Since crack sealing tape is generally narrow and does not require much pressure, using small wheels is more suitable, as it allows for flexible compaction with the tape. However, the pressure provided by small wheels is relatively limited. Therefore, we propose a compaction tool for road crack repair to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a compaction tool for repairing road cracks, comprising a support plate, upright plates symmetrically fixedly arranged on the lower side of the support plate, a pressure roller rotatably arranged on the lower side of the upright plates that are close to each other, insert rods fixedly arranged side by side in the middle of the upper side of the support plate, counterweights stacked on the outer side of the insert rods, insertion holes corresponding to the insert rods on the upper side of the counterweights, the insert rods being inserted into the counterweights through the insertion holes, nuts threaded onto the upper ends of the insert rods, a handle rod fixedly arranged on one side of the support plate, and a handle ring fixedly arranged at the end of the handle rod away from the support plate.

[0007] The beneficial effects of this utility model are as follows: the handle ring drives the handle rod, the handle rod pushes the support plate, the support plate drives the pressure roller to move through the upright plate, the pressure roller moves along the seam tape and rolls it, the pressure roller is relatively small, the pressure roller is provided with counterweight by a counterweight block, the counterweight block can be added, removed, disassembled and transported separately through the insertion rod. Compared with the current hand-push single steel wheel, this device is more suitable for manual pushing operation, more flexible and easy to carry and transport.

[0008] To facilitate adjustment of the control length of the handle and extension bar as needed;

[0009] As a further improvement to the above technical solution: an extension rod is inserted into the end of the handle bar away from the handle ring, and two bolts are threaded in parallel on the upper side of the end of the handle bar near the extension rod, and the two bolts pass through the handle bar and press against the extension rod.

[0010] The beneficial effects of this improvement are: the telescopic extension rod is then fixed by tightening bolt two, which facilitates the adjustment of the control length of the handle and extension rod as needed.

[0011] For use in disassembling and replacing the extension bar and handle bar;

[0012] As a further improvement to the above technical solution: a fixing block is fixedly installed on the upper side of the support plate near the handle bar, the extension rod is inserted into the fixing block, and three bolts are inserted side by side on the outer side of the fixing block, all three bolts passing through the fixing block and threadedly connected to the extension rod.

[0013] The beneficial effects of this improvement are: it removes bolt three, which is used to disassemble and replace the extension rod and handle rod.

[0014] To facilitate the movement of the pressure roller;

[0015] As a further improvement to the above technical solution: a battery is fixedly installed on one side of the upper side of the support plate, and a motor is fixedly installed on one side of the upright plate. The output end of the motor passes through the upright plate and is fixedly connected to the center of the pressure roller. A controller is installed on the upper side of the handle bar near the handle ring.

[0016] The beneficial effects of this improvement are: the motor can be started by controlling the controller, and the output of the motor can drive the pressure roller to rotate, which makes it easier to move the pressure roller.

[0017] For use in maintaining and replacing the outer side of the pressure roller;

[0018] As a further improvement to the above technical solution: the pressure roller includes an inner roller, and a semi-circular outer shell is symmetrically arranged on the outer side of the inner roller. Connecting blocks are fixedly arranged at equal intervals on both sides of the semi-circular outer shell. A bolt is provided on the side of the connecting block away from the inner roller. The bolts are threaded through the connecting block and connected to the inner roller.

[0019] The beneficial effects of this improvement are: the outer side of the pressure roller is prone to rust and wear due to frequent use. By disassembling bolt one, the semi-circular outer shell can be disassembled and replaced for maintenance and replacement of the outer side of the pressure roller.

[0020] To increase the friction between the semi-circular shell and the ground;

[0021] As a further improvement to the above technical solution: protrusions are evenly provided on both sides of the semi-circular outer shell.

[0022] The beneficial effect of this improvement is that it increases the friction between the semi-circular shell and the ground.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0030] like Figure 1 — Figure 4As shown: A compaction tool for repairing road cracks includes a support plate 1. Vertical plates 2 are symmetrically fixed to the lower side of the support plate 1. A pressure roller 3 is rotatably mounted on the lower side of the vertical plates 2, which are close to each other. Insert rods 4 are fixedly arranged side-by-side in the middle of the upper side of the support plate 1. Counterweights 5 are stacked on the outer sides of the insert rods 4. Insertion holes 51 are opened on the upper side of the counterweights 5 corresponding to the insert rods 4. The insert rods 4 are inserted into the counterweights 5 through the insertion holes 51. Nuts 6 are threaded onto the upper ends of the insert rods 4. A handle 8 is fixedly mounted on one side of the support plate 1. A handle ring 9 is fixedly mounted on the end of the handle 8 away from the support plate 1. The handle 8 is driven by the handle ring 9, and pushed by the handle 8. Support plate 1, via upright plate 2, drives pressure roller 3 to move. Pressure roller 3 moves along the seam tape and rolls it. Pressure roller 3 is relatively small and is counterweighted by counterweight block 5. Counterweight block 5 can be added, removed, disassembled, and transported separately via insert rod 4. Compared to the current hand-push single steel wheel, this device is more suitable for manual operation, more flexible, and easier to carry and transport. An extension rod 13 is inserted into the end of the handle 8 away from the handle ring 9. Two bolts are threaded in parallel on the upper side of the end of the handle 8 near the extension rod 13. Both bolts pass through the handle 8 and press the extension rod 13 together. The extension rod 13 is extended and then fixed by tightening the bolts, which facilitates adjustment of the handle 8 and extension rod as needed. The extension rod 13 controls the length of the handle 8. A fixing block 7 is fixedly installed on the upper side of the support plate 1 near the handle 8. The extension rod 13 is inserted into the fixing block 7. Bolts 3 are inserted side by side on the outer side of the fixing block 7. All three bolts pass through the fixing block 7 and are threadedly connected to the extension rod 13. The bolts 3 are removed to disassemble and replace the extension rod 13 and the handle 8. A battery 10 is fixedly installed on one side of the upper side of the support plate 1. A motor 11 is fixedly installed on the upright plate 2 on the other side. The output end of the motor 11 passes through the upright plate 2 and is fixedly connected to the center of the pressure roller 3. A controller 12 is installed on the upper side of the handle 8 near the handle ring 9. The controller 12 controls the motor 11 to start. The output end of 1 can drive the pressure roller 3 to rotate, which facilitates the movement of the pressure roller 3. The pressure roller 3 includes an inner roller 31. A semi-circular outer shell 32 is symmetrically arranged on the outer side of the inner roller 31. A connecting block 33 is fixedly arranged at equal intervals on both sides of the semi-circular outer shell 32. A bolt 34 is arranged on the side of the connecting block 33 away from the inner roller 31. The bolt 34 passes through the connecting block 33 and is threaded to the inner roller 31. The outer side of the pressure roller 3 is prone to rust and wear with frequent use. By disassembling the bolt 34, the semi-circular outer shell 32 can be disassembled and replaced for maintenance and replacement of the outer side of the pressure roller 3. The two sides of the semi-circular outer shell 32 are evenly arranged with protrusions 35 to increase the friction between the semi-circular outer shell 32 and the ground.

[0031] Working principle and usage process of this utility model:

[0032] In use, the handle ring 9 drives the handle lever 8, which in turn pushes the support plate 1. The support plate 1, via the upright plate 2, moves the pressure roller 3. The pressure roller 3 moves along the seam tape and presses it down. The pressure roller 3 is relatively small and is counterweighted by a counterweight block 5. The counterweight block 5 can be added, removed, disassembled, and transported separately via the insert rod 4. Compared to the current hand-push single steel wheel, this device is more suitable for manual operation, more flexible, and easier to carry and transport. In addition, an extension rod 13 is inserted into the end of the handle lever 8 away from the handle ring 9. Two bolts are threaded in parallel on the upper side of the handle 8 near the extension rod 13. Both bolts penetrate the handle 8 and press against the extension rod 13. The extension rod 13 is extended or retracted, and then fixed by tightening the bolts. This allows for easy adjustment of the control length of the handle 8 and extension rod 13 as needed. Additionally, a fixing block 7 is fixedly installed on the upper side of the support plate 1 near the handle 8. The extension rod 13 is inserted into the fixing block 7. Three bolts are threaded in parallel on the outer side of the fixing block 7. These bolts penetrate the fixing block 7 and connect to the extension rod 13. The bolts can be removed... This is used for disassembling and replacing the extension rod 13 and the handle rod 8. In addition, a battery 10 is fixedly installed on one side of the upper side of the support plate 1, and a motor 11 is fixedly installed on one side of the upright plate 2. The output end of the motor 11 passes through the upright plate 2 and is fixedly connected to the center of the pressure roller 3. A controller 12 is installed on the upper side of the end of the handle rod 8 near the handle ring 9. The controller 12 controls the motor 11 to start. The output end of the motor 11 can drive the pressure roller 3 to rotate, which facilitates the movement of the pressure roller 3. In addition, the pressure roller 3 includes an inner wheel 31, and the outer sides of the inner wheel 31 are symmetrically arranged. There is a semi-circular outer shell 32. Connecting blocks 33 are fixedly installed at equal intervals on both sides of the semi-circular outer shell 32. Bolts 34 are installed on the side of the connecting blocks 33 away from the inner wheel 31. Bolts 34 pass through the connecting blocks 33 and are threaded to the inner wheel 31. The outer side of the pressure roller 3 is prone to rust and wear with frequent use. By disassembling the bolts 34, the semi-circular outer shell 32 can be disassembled and replaced for maintenance and replacement of the outer side of the pressure roller 3. In addition, protrusions 35 are evenly arranged on both sides of the semi-circular outer shell 32 to increase the friction between the semi-circular outer shell 32 and the ground.
