Description

Technical Field

[0001] This invention relates to the field of road surface crack repair, and more specifically, to a road surface crack repair device and repair method. Background Technology

[0002] Over long-term use, road surfaces are prone to cracking. To ensure smooth vehicle operation and prevent further cracking, repairs are often necessary. Common repair methods fall into two main categories: grouting and crack sealing tape. For smaller cracks, such as those less than 10mm, grouting requires cutting grooves, making it less than ideal in terms of equipment requirements and construction complexity. Crack sealing tape, on the other hand, provides a simple and convenient repair without damaging the original road surface. Larger cracks are typically repaired using grouting methods, with materials such as polyurethane, epoxy resin, and cement grout. If a road has both small and large cracks, different equipment is often needed for grouting and crack sealing tape methods.

[0003] There is an urgent need for a device that combines two repair methods into one, reducing the amount of equipment to carry when repairing road surface cracks. Summary of the Invention

[0004] The purpose of this invention is to provide a road surface crack repair device that solves the problem that existing repair devices cannot simultaneously perform grouting repair and crack sealing tape repair.

[0005] The purpose of this invention is to provide a method for repairing road cracks, which allows for easy switching between injection repair and crack sealing tape repair.

[0006] The embodiments of the present invention are achieved through the following technical solutions:

[0007] A road crack repair device includes a vehicle body, a storage tank, and a crack filling pipe. The storage tank is mounted on the top wall of the vehicle body and connected to the crack filling pipe. The device further includes: a rotating rod rotatable about its central axis; a compaction roller and a crack-sealing tape, respectively disposed on opposite sides of the rotating rod; a release liner passing through the rotating rod and opposite to the crack-sealing tape; a drive gear connected to the side wall of the crack-sealing tape; a driven gear meshing with the drive gear and connected to the side wall of the release liner; and a drive mechanism for driving the rotating rod to rotate.

[0008] Preferably, the diameter of the drive gear is smaller than the diameter of the seam sealing tape tube.

[0009] Preferably, it includes: a transition cylinder, wherein the isolation membrane segment connecting the isolation membrane cylinder and the seam sealing tape cylinder is wound around the transition cylinder.

[0010] Preferably, the horizontal distance between the transition tube and the isolation membrane tube is greater than the horizontal distance between the seam sealing tape tube and the isolation membrane tube.

[0011] Preferably, it includes: a first rod body, the side wall of the rotating rod being connected to one end of the first rod body; a second rod body, the second rod body being connected to the other end of the first rod body, the second rod body being parallel to the rotating rod, and the seam sealing tape sleeve being fitted onto the second rod body.

[0012] Preferably, the driving device includes: a telescopic mechanism, the output shaft of which is connected to the first rod or the second rod, and the output shaft has a vertical range of motion.

[0013] Preferably, the telescopic mechanism is located above the first or second rod, and the output shaft of the telescopic mechanism is located below the telescopic mechanism.

[0014] Preferably, it includes: a mounting plate, the bottom wall of which is connected to the vehicle body, the mounting plate having a through hole for the output shaft to pass through, and the vertical downward projection of the mounting plate at least covering the seam sealing tape tube.

[0015] Preferably, it includes: a connecting shaft, one end of which is fixedly connected to the vehicle body, and the other end of which is rotatably connected to the end of the rotating rod away from the isolation membrane cylinder.

[0016] A method for repairing road cracks includes: a crack-sealing tape repair method: using the aforementioned road crack repair device, firstly, the crack-sealing tape is rolled into a crack-sealing tape cylinder, the release film at the starting end of the crack-sealing tape is connected to the release film cylinder, then the drive mechanism is activated to make the crack-sealing tape cylinder abut against the crack in the ground, and finally the trolley is moved along the direction of the crack extension to achieve road crack repair; a grouting repair method: firstly, the crack is cleaned and repaired, then the aforementioned road crack repair device is used to grout the crack from the storage tank, then sand and gravel are laid to cover the crack, the drive mechanism is used to make the compaction roller contact the ground and roll along the surface of the sand and gravel, and finally the sand and gravel remaining around the crack are cleaned.

[0017] The present invention has at least the following beneficial effects:

[0018] This invention simplifies the switching between the injection repair method and the joint sealing tape repair method by setting a rotating rod and placing the compaction roller and the joint sealing tape cylinder on opposite sides of the rotating rod.

[0019] The present invention incorporates a transition tube to prevent the release film from becoming too loose when winding up the release film that has detached from the seam tape, thus affecting the winding effect.

[0020] This invention reduces the amount of release film detachment from the seam sealing tape when the seam sealing tape is finished by setting a specific transition tube position.

[0021] This invention switches between two repair methods through specific means and structures, so that when the seam tape repair method is implemented, the height of the release liner tube is greater than that of the seam tape tube, which can further reduce the amount of release liner detachment on the seam tape when the seam tape repair is completed.

[0022] The mounting plate designed in this invention not only supports the drive mechanism but also prevents rainwater from wetting the seam sealing tape. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, methods, and advantages of the embodiments of the present invention clearer, the method solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] like Figure 1-2 As shown, a road crack repair device includes a vehicle body 1, a storage tank 2, and a crack filling pipe 3. The storage tank 2 is mounted on the top wall of the vehicle body 1 and is connected to the crack filling pipe 3. The device also includes: a rotating rod 4, which is rotatable around its central axis; a compaction roller 5 and a crack sealing tape 6, which are respectively disposed on both sides of the rotating rod 4; a release membrane 7, which passes through the rotating rod 4 and is positioned opposite to the crack sealing tape 6; a driving gear 8, which is connected to the side wall of the crack sealing tape 6; a driven gear 9, which meshes with the driving gear 8 and is connected to the side wall of the release membrane 7; and a drive mechanism 10, which drives the rotating rod 4 to rotate.

[0041] In practice, there are many ways to drive the rotating rod 4 to rotate, such as manually rotating it using a handwheel or connecting it to a rotary motor to rotate the rod 4. The compaction roller 5 can be referenced... Figure 1-2As shown, symmetrical L-shaped rods 16 are mounted on the side wall of the rotating rod 4. Since the compaction roller 5 is generally larger than the seam sealing tape cylinder 6, to reduce the distance between the rotating rod 4 and the vehicle body 1, thereby increasing the connection stability of the rotating rod 4, it can be arranged as follows: Figure 1 As shown, the seam sealing tape tube 6 is positioned on the side of the rotating rod 4 near the vehicle body 1.

[0042] When using the crack repair method with sealing tape, the sealing tape is first rolled up into the sealing tape tube 6. The release film at the starting end of the sealing tape is connected to the release film tube 7. A clamping device for fixing the starting end of the release film can be provided at the end of the release film tube 7. Then, the drive mechanism 10 is activated to make the sealing tape tube 6 come into contact with the crack in the ground. Finally, the trolley is moved along the direction of the crack extension to complete the road crack repair. When the trolley is moved, the sealing tape tube 6 rotates, which drives the drive gear 8 to rotate. The drive gear 8 drives the driven gear 9, which drives the release film tube 7 to rotate. This achieves synchronous winding of the release film during the sealing tape application process, and the winding power of the release film comes from the rotation of the sealing tape tube 6, eliminating the need for an additional drive device and reducing the manufacturing cost of the equipment.

[0043] Reference Figures 3-5 As shown, there are several ways to wind up the release film, such as... Figure 3 When the release liner is wound as shown, the rotation direction of the release liner tube 7 is opposite to that of the seam sealing tape tube 6, and according to... Figure 4 and Figure 5 When the release liner is wound as shown, the rotation direction of the release liner tube 7 is the same as that of the seam sealing tape tube 6. If the rotation direction of the release liner tube 7 is the same as that of the seam sealing tape tube 6, then an even number of driven gears 9 need to be set. Ideally, two driven gears 9 should be set.

[0044] In order to avoid the edge of the drive gear 8 affecting the rolling of the seam sealing tape 6, in this embodiment, the diameter of the drive gear 8 is smaller than the diameter of the seam sealing tape 6.

[0045] In the specific implementation process, it can be as follows: Figure 1 As shown, a single driven gear 9 with a larger diameter can be directly set to mesh with the driving gear 8. Alternatively, to reduce the diameter of the driven gear 9, multiple meshing driven gears 9 can be set. By controlling the odd or even number of driven gears 9, the rotation directions of the sealing tape cylinder 6 and the separating film cylinder 7 can be controlled to adapt to... Figure 3-5 Different methods of wrapping the isolation membrane.

[0046] To prevent the release film from loosening during the winding process, it is not advisable to neatly wind it up together, such as... Figure 6-8 As shown, in this embodiment, it includes: a transition cylinder 11, and the isolation membrane segment connecting the isolation membrane cylinder 7 and the seam sealing tape cylinder 6 is wound around the transition cylinder 11.

[0047] In specific implementation, the connection relationship of the transition cylinder 11 can be varied. For example, a side plate can be set next to the sealing tape cylinder 6, and the transition cylinder 11 can be connected through the side plate. Alternatively, the transition cylinder 11 can be installed on a rod connected to the side wall of the rotating rod 4. In this case, the connection between the transition cylinder 11 and which component of the device is not specifically limited. The isolation membrane segment refers to the section between the tangent point of the isolation membrane and the isolation mold cylinder and the tangent point of the isolation membrane and the sealing tape cylinder 6.

[0048] If transition cylinder 11 is not provided, refer to Figure 3 and Figure 5 In the diagram, the dotted line represents the release liner, and the bottom horizontal solid line represents the attached seam tape body 17. As can be seen from the diagram, the force maintaining the tension of the release liner section relies on the release liner tube 7 and the adhesive between the release liner and the seam tape body 17; at this point, the release liner is prone to loosening. See also... Figure 10 As shown, the pre-detachment length of the release liner is relatively long at this time. After the crack is repaired with the sealant tape, a large number of sealant tape bodies 17 with the release liner peeled off will not be used, resulting in waste.

[0049] The location of the transition cylinder 11 can be referenced. Figures 6-9 As shown, the tangent position between the release film segment and the sealing tape tube 6 can be changed by the transition tube 11, so that the tangent position is as close as possible to the bonding point between the sealing tape body 17 and the crack, thereby reducing the pre-detachment length of the release film.

[0050] from Figure 7 and Figure 9 As can be seen from the comparison, Figure 9 When the central axes of the release liner 7 and the seam sealing tape 6 are at the same horizontal height, the point of tangency between the release liner segment and the seam sealing tape 6 is difficult to move to the right beyond the highest point of the seam sealing tape 6. This invention achieves functional switching through the up-and-down swinging of the seam sealing tape 6 and the compaction roller 5, which precisely ensures that in the seam sealing tape repair mode, the release liner 7 tilts upwards, higher than the seam sealing tape 6, thus achieving... Figure 7 As shown, the cutting point should be moved as far to the right of the sealing tape tube 6 as possible. Theoretically, the greater the inclination angle of the isolation film segment, the greater the distance the cutting point moves, the smaller the pre-detachment length of the isolation film, and the less waste of the sealing tape.

[0051] To minimize the pre-detachment length of the separator membrane, such as Figure 7 As shown, in this embodiment, the horizontal distance between the transition cylinder 11 and the isolation membrane cylinder 7 is greater than the horizontal distance between the seam sealing tape cylinder 6 and the isolation membrane cylinder 7.

[0052] In the specific implementation process, through Figure 7 and Figure 6 or Figure 8 The comparison shows that the optimal setting position of the transition cylinder 11 is slightly lower to the right of the seam sealing tape cylinder 6.

[0053] The optimal one could also be like... Figure 11 As shown, by setting multiple transition cylinders 11, the pre-detachment length of the separator membrane will be further reduced.

[0054] like Figure 1-2 As shown, in this embodiment, it includes: a first rod 12, the side wall of the rotating rod 4 is connected to one end of the first rod 12; a second rod 13, the second rod 13 is connected to the other end of the first rod 12, the second rod 13 is parallel to the rotating rod 4, and the seam sealing tape 6 is sleeved on the second rod 13.

[0055] In the specific implementation process, the sealing tape tube 6 can rotate around the second rod 13. The isolation film tube 7 can theoretically be set on the aforementioned side plate like the transition tube 11. In this case, the isolation film tube 7 is inserted through the rotating rod 4, which can ensure that the distance between the sealing tape tube 6 and the isolation film tube 7 is fixed, and the isolation film will not loosen or detach from the sealing tape body 17 due to the rotation of the rotating rod 4.

[0056] To reduce the driving force required by the drive unit when switching between two different repair methods, such as Figure 1-2 As shown, in this embodiment, the driving device includes a telescopic mechanism, the output shaft 101 of which is connected to the first rod 12 or the second rod 13, and the output shaft 101 has a vertical range of motion.

[0057] In practice, based on the lever principle, the farther the output shaft 101 is from the rotating rod 4, the less force is required. In the joint sealing tape repair mode, the output shaft 101 extends, pressing the joint sealing tape cylinder 6 down to contact the ground, while applying a certain downward pressure to assist in the stable adhesion of the joint sealing tape. When switching to the injection repair mode, the output shaft 101 retracts, causing the compaction roller 5 to contact the ground and applying a certain downward pressure.

[0058] The drive unit can be a telescopic cylinder or a hydraulic cylinder.

[0059] like Figure 1-2 As shown, in this embodiment, the telescopic mechanism is located above the first rod 12 or the second rod 13, and the output shaft 101 of the telescopic mechanism is located below the telescopic mechanism.

[0060] In practice, the telescopic mechanism can also be set below the first rod 12 or the second rod 13. However, since the space below is small, the installation and telescopic operation of the telescopic mechanism are easily restricted. Therefore, in this case, the telescopic mechanism is set above the first rod 12 or the second rod 13.

[0061] To facilitate the installation of the telescopic mechanism and prevent the sealing tape from getting wet from rain, such as Figure 1As shown, in this embodiment, it includes: a mounting plate 14, the bottom wall of which is connected to the vehicle body 1, the mounting plate 14 having a through hole for the output shaft 101 to pass through, and the vertical downward projection of the mounting plate 14 at least covering the seam sealing tape 6.

[0062] In practical implementation, having the telescopic mechanism positioned at the top has another advantage: the mounting plate 14 can be used to conceal the seam sealing tape cylinder 6. Ideally, such as... Figure 1 As shown, the mounting plate 14 can completely cover the sealing tape tube 6 and the release liner tube 7. To ensure the strength of the mounting plate 14, it can be as follows: Figure 12 The reinforcing rib 141 is shown.

[0063] To ensure the stability of the rotating rod 4 during installation, such as Figure 1-2 As shown, in this embodiment, it includes: a connecting shaft 15, one end of which is fixedly connected to the vehicle body 1, and the other end of which is rotatably connected to the end of the rotating rod 4 away from the isolation membrane cylinder 7.

[0064] In the specific implementation process, it can be as follows: Figure 1 As shown, connecting shafts 15 are provided at both ends of the rotating rod 4 to ensure the stability of the rotating rod 4. Optimally, [the following option is selected]. Figure 13 As shown, a connecting shaft 15 is only provided at the end of the rotating rod 4 away from the release diaphragm cylinder 7. This has the advantage of facilitating the assembly and disassembly of the release diaphragm cylinder 7 and the sealing tape cylinder 6 for easy replacement of the sealing tape. Both the driving gear 8 and the driven gear 9 can be detachably connected to the release diaphragm cylinder 7 or the sealing tape cylinder 6, for example, by bolt 18. See reference [link / reference needed] for details. Figure 14 As shown, the drive gear 8 is provided with a cylinder 81, which is located between the second rod 13 and the seam sealing tape cylinder 6. Bolts 18 fix the seam sealing tape cylinder 6 and the cylinder 81.

[0065] In this invention, a stirring device and a heating device can be installed inside the storage tank 2 to ensure the uniformity and fluidity of the injection liquid. The crack filling pipe 3 can be equipped with a pump body 31 and a switch 32. In order for the crack filling pipe 3 to extend into the crack, a telescopic pipe 33 can also be installed in the vertical section of the crack filling pipe 3. In addition, a dust collection device, a washing device, and a drying device can be integrated on the vehicle body 1, which are all existing technologies and will not be described in detail.

[0066] A method for repairing road cracks includes: a crack-sealing tape repair method: using the aforementioned road crack repair device, firstly, the crack-sealing tape is rolled into the crack-sealing tape cylinder 6, the release film at the starting end of the crack-sealing tape is connected to the release film cylinder 7, then the drive mechanism 10 is activated to make the crack-sealing tape cylinder 6 come into contact with the crack on the ground, and finally the trolley is moved along the direction of the crack extension to achieve road crack repair; a grouting repair method: firstly, the crack is cleaned and repaired, then the crack-sealing liquid in the storage tank 2 is grouted into the crack using the aforementioned road crack repair device, then sand and gravel are laid to cover the crack, the drive mechanism 10 is used to make the compaction roller 5 contact the ground and roll along the surface of the sand and gravel, and finally the sand and gravel remaining around the crack are cleaned.

[0067] In practice, after the sealing tape is applied, there are two operating methods. One is to cut off the detached release film at the cutting point between the release film and the sealing tape tube 6, and then continue to move the trolley to attach the remaining sealing tape body 17, which has detached from the release film, to the ground. The disadvantage is that the end of the release film needs to be re-fixed to the release film tube 7 for the next use. The second method is not to cut off the release film, but to cut the sealing tape at the cutting point. In this case, a part of the sealing tape body 17 that has detached from the release film is left on the sealing tape tube 6. This part can be manually pasted onto the ground.

[0068] To ensure the adhesion stability of the seam tape, the seam tape can be rolled again using a compaction roller 5.

[0069] Cleaning in the grouting repair method mainly includes removing debris and dust from the cracks. Finishing mainly refers to cutting and grooving the cracks to allow the grouting fluid to fully penetrate them. Laying sand and gravel prevents the grouting fluid from being carried away before it fully solidifies, while using a compaction roller to roll the sand and gravel allows it to enter the cracks, ensuring the sand and gravel layer is flush with the surrounding ground and remains flat.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
