Description

Technical Field

[0001] This utility model relates to the field of road surface crack repair, and in particular to an integrated device for rapid repair of highway road surface cracks. Background Technology

[0002] Over time, highways often develop long, narrow cracks due to foundation subsidence. These cracks require immediate repair. Current repair methods involve manual processes such as marking lines, breaking up the cracked surface, manually cleaning debris, and laying repair materials, which are extremely time-consuming. With advancements in technology, milling equipment has emerged that automatically breaks up the road surface by moving along the crack's path, significantly improving repair efficiency. However, in practice, the milled debris still needs manual removal. This typically involves one person holding a material-carrying trolley while one or two others shovel the debris. This manual removal not only increases the workload but also has limited efficiency. Therefore, this paper proposes an integrated rapid repair device for highway road cracks to address these issues. Utility Model Content

[0003] In view of the above-mentioned problems in the existing technology, the main purpose of this utility model is to provide an integrated device for rapid repair of cracks in highway pavement. The first motor on the outside of the moving frame drives the rotating shaft to rotate, and the rotating shaft drives the agitator plate to rotate, which agitates the milled pavement fragments so that the fragments can enter the conveying sleeve through the conveying chute for automatic conveying. The integrated milling and material collection device realizes the automated processing of fragments, which can greatly reduce the labor intensity of workers and improve work efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated device for rapid repair of cracks in highway pavement, comprising a mobile carrier and a milling device;

[0005] The traveling end of the mobile carrier is equipped with milling equipment for milling the road surface.

[0006] The other end of the mobile carrier is equipped with a connecting cover, and a vertically installed lifting hydraulic rod is installed inside the connecting cover. The free end of the lifting hydraulic rod is fixedly connected to a slag handling mechanism.

[0007] A material collection trolley is provided on the side of the debris handling mechanism to collect the road debris discharged by the mechanism.

[0008] Furthermore, both sides of the lifting hydraulic rod are provided with guide cylinders that are fixedly connected to the connecting cover. The inside of each guide cylinder is slidably connected with a vertically arranged guide rod, and the other end of the guide rod is fixedly connected to the top of the slag processing mechanism.

[0009] Furthermore, the slag handling mechanism includes a movable frame whose top is fixedly connected to the free end of the lifting hydraulic rod. The movable frame moves freely up and down under the action of the lifting hydraulic rod. A first motor is installed on the side of the movable frame. A rotating shaft is fixedly connected to the end of the main shaft of the first motor. Evenly distributed actuating plates are fixedly connected to the outside of the rotating shaft.

[0010] Over time, highways often develop long, narrow cracks in the road surface due to foundation subsidence. These cracks require timely repair. Current repair methods involve manual marking, breaking up the cracked surface, manually cleaning up debris, and laying repair materials – all of which are extremely time-consuming. With advancements in technology, milling equipment has emerged that automatically breaks up the road surface by moving along the crack's path, significantly improving repair efficiency. However, in practice, the milled debris still needs to be manually cleaned up, typically by one person holding a material-carrying trolley while another... One or two people are needed to remove the debris manually. This method not only increases the labor intensity of the workers, but also has lower efficiency. When in use, the power is turned on. This device has a debris handling mechanism on one side of the moving carrier. When the moving carrier moves, the first motor on the outside of its moving frame drives the rotating shaft to rotate. The rotating shaft drives the actuating plate to rotate. At this time, the road debris after milling can be actuated so that the debris can enter the conveying sleeve through the conveying chute for automatic conveying. The integrated milling and material collection equipment realizes the automated handling of debris, which can greatly reduce the labor intensity of the workers and improve work efficiency.

[0011] Furthermore, a material conveying trough is also provided inside the moving frame. The bottom surface of the material conveying trough is inclined, and the material conveying trough is long and narrow.

[0012] Furthermore, a longitudinally arranged conveying sleeve is installed inside the moving frame. A second motor is fixedly connected inside the conveying sleeve. A conveying shaft is fixedly connected to the end of the main shaft of the second motor. Evenly distributed conveying blades are fixedly connected to the outside of the conveying shaft.

[0013] Furthermore, a strip-shaped feed chute is provided on one side of the conveying sleeve.

[0014] Furthermore, the conveying sleeve protrudes from one side of the moving frame, and an inclined feeding pipe is installed on the protruding part of the conveying sleeve.

[0015] The second motor drives the conveyor shaft to rotate, which in turn drives the conveyor blades to rotate. The crushed material enters the conveyor sleeve through the feed chute. The material is conveyed by the slow rotation of the conveyor blades and then discharged through the discharge chute, so that the crushed material falls into the collection trolley. By changing the collection trolley, the crushed material can be collected in a centralized manner.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] A slag handling mechanism is added to one side of the mobile carrier. When the mobile carrier moves, the first motor on the outside of its moving frame drives the rotating shaft to rotate, and the rotating shaft drives the actuating plate to rotate. At this time, the milled road debris can be actuated so that the debris can enter the conveying sleeve through the conveying chute for automatic conveying. The integrated milling and collecting equipment realizes the automated processing of debris, which can greatly reduce the labor intensity of workers and improve work efficiency.

[0018] The second motor drives the conveyor shaft to rotate, which in turn drives the conveyor blades to rotate. The crushed material enters the conveyor sleeve through the feed chute. The material is conveyed by the slow rotation of the conveyor blades and then discharged through the discharge chute, so that the crushed material falls into the collection trolley. By changing the collection trolley, the crushed material can be collected in a centralized manner. Attached Figure Description

[0023] 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 some embodiments of this utility model, but not all embodiments.

[0024] Example

[0025] An integrated device for rapid repair of highway pavement cracks, such as Figure 1-3 As shown, it includes a mobile carrier 1 and a milling machine 2;

[0026] The traveling end of the mobile carrier 1 is equipped with a milling device 2 for milling the road surface;

[0027] The other end of the mobile carrier 1 is equipped with a connecting cover 3. Inside the connecting cover 3, a vertically installed lifting hydraulic rod 4 is installed. The free end of the lifting hydraulic rod 4 is fixedly connected to a slag processing mechanism 5.

[0028] A material collection trolley 8 is provided on the side of the debris handling mechanism 5 to collect the road debris discharged by the debris handling mechanism 5.

[0029] Both sides of the lifting hydraulic rod 4 are provided with guide cylinders 6 that are fixedly connected to the connecting cover 3. The guide cylinders 6 are slidably connected with vertically arranged guide rods 7. The other end of the guide rods 7 is fixedly connected to the top of the slag processing mechanism 5.

[0030] The slag handling mechanism 5 includes a movable frame 501 whose top is fixedly connected to the free end of the lifting hydraulic rod 4. The movable frame 501 moves freely up and down under the action of the lifting hydraulic rod 4. A first motor 502 is installed on the side of the movable frame 501. A rotating shaft 503 is fixedly connected to the end of the main shaft of the first motor 502. Evenly distributed actuating plates 504 are fixedly connected to the outside of the rotating shaft 503.

[0031] The movable frame 501 is also provided with a material conveying trough 505. The bottom surface of the material conveying trough 505 is inclined and the material conveying trough 505 is long and narrow.

[0032] Over time, highways often develop long, narrow cracks in the road surface due to foundation subsidence. These cracks require timely repair. Current repair methods involve manual marking, breaking up the cracked surface, manually cleaning up debris, and laying repair materials – all of which are extremely time-consuming. With advancements in technology, milling equipment has emerged that automatically breaks up the road surface by moving a pneumatically driven vehicle along the crack's path, significantly improving repair efficiency. However, in practice, the milled debris still needs to be manually cleaned up. This typically involves one person holding the material-carrying trolley while one or two other people work on the broken-up material. The manual removal of debris not only increases the labor intensity of workers, but also has the need to improve removal efficiency. When in use, the power is turned on. This device has a debris handling mechanism 5 added to one side of the mobile carrier 1. When the mobile carrier 1 moves, the first motor 502 on the outside of its moving frame 501 drives the rotating shaft 503 to rotate. The rotating shaft 503 drives the agitator plate 504 to rotate. At this time, the road debris after milling can be agitated so that the debris can enter the conveying sleeve 506 through the conveying chute 505 for automatic conveying. The setting of the integrated milling and material collection equipment realizes the automated handling of debris, which can greatly reduce the labor intensity of workers and improve work efficiency.

[0033] The combined use of guide cylinder 6 and guide rod 7 can ensure the stable up and down movement of slag handling mechanism 5, and at the same time ensure the normal use of lifting hydraulic rod 4;

[0034] When the material trolley 8 is manually pushed, it is tilted to ensure that the material falls smoothly into the trolley 8. By having two or more people switch the trolley 8 back and forth, uninterrupted material collection can be achieved without stopping the machine. The bottom of the moving frame 501 is protruding, which works with the actuating plate 504 to ensure that the material falls smoothly into the conveying trough 505 for continuous material collection.

[0035] Furthermore, the mobile carrier 1 in this configuration needs to move slowly, generally at a speed of 5-15 meters per minute, to ensure that the road surface is milled stably and that the road debris is effectively processed after milling.

[0036] The moving frame 501 is also equipped with a longitudinally arranged conveying sleeve 506. A second motor 507 is fixedly connected inside the conveying sleeve 506. A conveying shaft 508 is fixedly connected to the end of the main shaft of the second motor 507. Evenly distributed conveying blades 509 are fixedly connected to the outside of the conveying shaft 508.

[0037] A feed chute 511 in the shape of a strip is provided on one side of the conveying sleeve 506.

[0038] The conveying sleeve 506 protrudes from one side of the moving frame 501, and an inclined feeding pipe 510 is installed on the protruding part of the conveying sleeve 506.

[0039] The second motor 507 drives the conveyor shaft 508 to rotate, and the conveyor shaft 508 drives the conveyor blades 509 to rotate. The crushed material enters the conveyor sleeve 506 through the feed chute 511. The material can be conveyed by the slow rotation of the conveyor blades 509. Then it is discharged through the discharge chute 510, so that the crushed material falls into the collection trolley 8. The crushed material can be collected centrally by changing the collection trolley 8.

[0040] The feed pipe 510 is set at an angle, which helps the material to fall fully.

[0041] Finally, it should be noted that the above-described 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
