Description

Technical Field

[0001] This utility model relates to the technical field of road maintenance and repair equipment, and in particular to a road maintenance crack repair device. Background Technology

[0002] Over long-term use, asphalt concrete pavements are prone to developing various types of cracks, such as transverse cracks, longitudinal cracks, and network cracks, due to factors such as load, temperature changes, and water erosion. If not repaired in time, these cracks will expand rapidly, leading to serious consequences such as potholes and damage to the base layer, significantly shortening the pavement's service life. Therefore, crack repair is a crucial aspect of preventative pavement maintenance.

[0003] Currently, in addition to manual repair, road crack repair is also carried out using repair equipment. For example, Chinese utility model patent with publication number CN221645531U discloses a crack repair device for highway maintenance. This repair device has a rectangular support base plate with four wheels. A repair pipe is set on one side of the top of the support base plate. The bottom of the repair pipe has a connector that corresponds to the crack in the road surface. Then, a handrail is set on the other side of the top of the support plate. During operation, the repair pipe and connector in front of the support base plate are pushed by the handrail to inject repair fluid into the crack in the road surface, which facilitates road repair and reduces the intensity of manual work.

[0004] In actual operation, most road surface cracks are long and irregular strips with varying degrees of curvature. The aforementioned repair device is limited by the volume of its supporting base plate. During operation, it not only affects the worker's vision but also prevents the repair fluid from being injected into these irregular cracks in a flexible and precise manner. Utility Model Content

During the repair process, the discharge position of the discharge pipe can be changed by sliding the rotating frame set on the base, so as to flexibly align with the bending path of the crack. At the same time, the casters at the bottom of the base can improve the flexibility of the device during operation.

[0008] In some embodiments, the rotating frame includes a semi-circular curved rod and two connecting rods respectively fixedly disposed at the bottom of both ends of the curved rod. The curved rod has a mounting hole in the middle for installing the injection cylinder. The bottom ends of the two connecting rods are fixedly connected to the same straight rod.

[0024] In an exemplary implementation, such as Figures 1-5As shown, this embodiment provides a road surface maintenance crack repair device, including a base 100, a rotating frame 200, a material injection cylinder 300, a material discharge pipe 400, and a wheel set 500. The top of the base 100 is provided with a material tank 110 for storing repair material. The rotating frame 200 is rotatably disposed on one side of the top of the base 100 and is used for reciprocating swing. The material injection cylinder 300 is installed on the rotating frame 200 and is connected to the material tank 110. The material discharge pipe 400 is disposed at the bottom of the material injection cylinder 300 and is used for discharging material. The wheel set 500 is installed at the bottom of the base 100 and includes universal wheels 510 to facilitate the turning of the base 100.

[0025] In this embodiment, a material tank 110 is provided on the base 100 to hold the repair material, and a set of wheels 500 for movement is provided at the bottom of the base 100. Furthermore, an injection cylinder 300 is provided on the side of the base 100 away from the material tank 110 to inject the repair material into the crack through the discharge pipe 400. During the repair process, the discharge position of the discharge pipe 400 can be changed by the rotating frame 200 slidably provided on the base 100, so as to flexibly align with the bending path of the crack. At the same time, the universal wheels 510 at the bottom of the base 100 can improve the flexibility of the device during operation.

[0026] In one embodiment, please refer to Figures 1-2 The rotating frame 200 includes a semi-circular curved rod 210 and two connecting rods 220 fixedly disposed at the bottom of both ends of the curved rod 210. The curved rod 210 has a mounting hole 211 for mounting the injection cylinder 300 in the middle. The bottom ends of the two connecting rods 220 are fixedly connected to the same straight rod 230. The bottom center of the straight rod 230 is rotatably connected to the center of one side of the top of the base 100.

[0027] In this embodiment, the curved rod 210 extends to the outside of the base 100, and the injection cylinder 300 is installed in the mounting hole 211 so that the bottom of the injection cylinder 300 can correspond to the road surface. At this time, the curved rod 210 is connected to the straight rod 230 through the connecting rod 220. The straight rod 230 is rotatably installed on one side of the edge of the base 100, and the curved rod 210 can rotate around the connection between the straight rod 230 and the base 100.

[0028] In one embodiment, please refer to Figures 1-2 Two extension rods 240 are arranged opposite each other on the end side of the base 100 near the straight rod 230. An arc-shaped groove 250 extending to the extension rod 240 is opened on the top side of the base 100 near the straight rod 230. Limiting blocks 260 that slide and connect with the inner walls of the two arc-shaped grooves 250 are respectively provided at the bottom of both ends of the straight rod 230. A handle 270 sleeved on the outside of the injection cylinder 300 is provided in the middle of the curved rod 210.

[0029] In this embodiment, the straight rod 230 slides within the arc-shaped groove 250 on the base 100 via the limiting block 260, thereby connecting with the base 100 and increasing the stability of the straight rod 230. The opening path of the arc-shaped groove 250 is the same as the movement path of the straight rod 230 driving the limiting block 260.

[0030] Specifically, the handle 270 can drive the crank 210 and the straight rod 230 to rotate horizontally left and right on the base 100. At this time, the crank 210 can drive the injection cylinder 300 to move, thereby dealing with cracks with irregular trajectories.

[0031] In one embodiment, please refer to Figure 1 and Figure 3 A corrugated pipe 310 connects the top of the injection cylinder 300 to the bottom of the material tank 110, and the top of the discharge pipe 400 is connected to the bottom of the injection cylinder 300.

[0032] In this embodiment, the material tank 110 introduces the repair material into the injection cylinder 300 through the corrugated pipe 310. Utilizing the flexibility of the corrugated pipe 310, it can adapt to the horizontally moving injection cylinder 300.

[0033] Furthermore, the material tank 110 is equipped with structural components that are present in the art, such as a stirring structure and a pumping structure, which are existing technologies and will not be described in detail.

[0034] In one embodiment, please refer to Figures 1-4 The discharge pipe 400 includes a fixed pipe 410 connected to the bottom of the injection cylinder 300 and an extension pipe 420 slidably sleeved outside the fixed pipe 410. The extension pipe 420 is threaded with a threaded sleeve 430. The outer side of the threaded sleeve 430 is slidably provided with a limit rod 440 fixedly connected to the bottom of the crank rod 210.

[0035] Among them, the outer fixed sleeve of the threaded sleeve 430 is provided with a rotating wheel 431.

[0036] In this embodiment, the rotatable screw sleeve 430 is connected to the crank rod 210 through the limiting rod 440. At this time, the extension tube 420 can move up and down outside the fixed tube 410 under the drive of the screw sleeve 430, thereby achieving the purpose of extending the fixed tube 410.

[0037] Furthermore, the wheel 431 on the outside of the threaded sleeve 430 can be used to improve the ease of rotating the threaded sleeve 430.

[0038] In one embodiment, please refer to Figures 1-2 The casters 510 are arranged in pairs on the bottom side of the base 100 near the injection cylinder 300, and the wheel set 500 also includes a pair of fixed wheels 520 installed on the bottom side of the base 100 away from the casters 510.

[0039] In this embodiment, the caster wheel 510 allows the base 100 to rotate extremely flexibly, further ensuring the accuracy of material injection.

[0040] In one embodiment, please refer to Figure 1 The base 100 has push handles 600 installed on both sides of the top of the caster wheel 510. The push handles 600 are used to push the device.

[0041] Furthermore, this device can also use an electric motor as a power source.

[0042] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail as follows: In use, a material tank 110 is set on the base 100 to hold the repair material. The material tank 110 guides the repair material into the injection cylinder 300 through the corrugated pipe 310. The injection cylinder 300 is installed in the mounting hole 211 so that the discharge pipe 400 at the bottom of the injection cylinder 300 can correspond to the road surface crack. Then, the device is pushed by the pusher 600. The device moves through the fixed wheel 520 and the universal wheel 510 at the bottom of the base 100.

[0043] Furthermore, during the repair process, the handle 270 can drive the curved rod 210 and the straight rod 230 to rotate horizontally left and right on the base 100. At this time, the curved rod 210 can drive the injection cylinder 300 to move, and the injection cylinder 300 can drive the discharge pipe 400 to change the discharge position, so as to flexibly align with the bending path of the crack.

[0044] In summary, this utility model uses a rotating frame 200 to drive the discharge pipe 400 to reciprocate horizontally to inject repair material into the crack. This solves the technical problem of the low injection flexibility of existing repair equipment, which makes it difficult to inject the repair fluid into the crack in a flexible and accurate manner. As a result, it improves the injection accuracy and thus the repair quality.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
