Description

Technical Field

[0001] The utility model relates to the technical field of road surface micro-cracking equipment, in particular to an intelligent micro-cracking vehicle for cement road surface micro-cracking. Background Art

[0002] The quality of highway roadbed filling and compaction will directly affect the settlement, deformation and stability of the roadbed. Therefore, the compaction degree of the roadbed must be strictly controlled during the construction process.

[0003] At present, the relevant equipment for roadbed compaction in my country is mainly ordinary rollers (including single-wheel, double-wheel, rubber-wheel), dynamic tamping machines, impact rollers, and other small machines. Ordinary rollers have the advantages of good compaction continuity and high surface flatness. At the same time, if it is a vibrating roller, it can also increase the effective compaction depth and improve the compaction efficiency. At present, Germany has developed BTM compaction monitoring equipment, which can perform self-inspection and control of compaction in real time. However, the equipment price is relatively high. At the same time, the compaction work of ordinary rollers is low, and it needs to be compacted back and forth to achieve the compaction effect. The effective compaction depth is also limited, generally 1m to 2m.

[0004] The dynamic tamping machine in the prior art has a large compaction influence depth that can reach 5m to 10m, and a high single-point compaction degree. Generally, only 1 to 3 tamping times are needed to achieve the required compaction degree. However, the dynamic tamping machine in the prior art requires large-scale machinery such as a crane or a gantry to operate, and generally compaction is performed at a single point, resulting in low compaction efficiency. At the same time, the compaction degree detection is troublesome, and the site requirements are high. More importantly, it is highly dangerous to construction personnel or inspection personnel, and has a great impact on surrounding buildings.

[0005] The impact rollers in the prior art have large compaction thickness and compaction impact depth, and good continuity, but they require large-scale mechanical traction, which causes inconvenience to the transportation process and has a great impact on the surrounding structures. In addition, they all use a single point for compaction, which requires repeated movement and has low compaction efficiency. Summary of the invention

The two rectangular frames 7 are arranged in a support frame 20. A hammer head shock-absorbing pad 8 is arranged between the rectangular frame 7 and the support frame 20. Since the rammer will generate a certain force on the frame and transmit it upward at the moment of ramming the ground, the shock-absorbing pad 8 can reduce the impact on the fuselage. A guide plate 19 which can move left and right along the support frame 20 is embedded in the bottom plate; a pair of tripods 6 are relatively arranged in the middle part of the outer side of the rectangular frame 7, a nylon wheel bracket is arranged on the rectangular frame 7 at the upper end of the tripod 6, a nylon wheel 1 is arranged in the nylon wheel bracket, and a support wheel bracket is arranged on the lower end rectangular frame 7, and a support wheel bracket is arranged on the support wheel bracket. A support wheel 10 in contact with the ground is arranged on the support wheel bracket, and the movement of the micro-cracking device is realized by the support wheel 10; a rammer connecting seat 14 is arranged between the pair of tripods 6, a steel wire rope 16 is arranged on the nylon wheel 1, one end of the steel wire rope 16 is connected to the hammer head steel wire rope fixing seat 15, and the other end is connected to the rammer connecting seat 14, and a hammer head 11 is fixedly connected to the hammer head steel wire rope fixing seat 15, and a lifting cylinder 2 is connected to the nylon wheel bracket, and the lifting cylinder 2 is used to realize the rise and fall of the nylon wheel bracket, driving the hammer head 11 to move up and down, and the lifting cylinder 2 is fixed to the rectangular frame 7 through the cylinder fixing plate 4. Figure 2-5 shown.

[0037] The above-mentioned flipping assembly 22 includes a flipping cylinder 22-1 and a hydraulic rod connecting member 22-4; the flipping cylinder 22-1 is connected to the hydraulic rod connecting member 22-4, one end of the hydraulic rod connecting member 22-4 is connected to the lower front end of the support plate 23-3, and the other end is connected to the connecting ear 13 of the guide plate 19. The A mechanism is tilted up and erected or flipped 90° by the extension and contraction of the hydraulic rod connecting member 22-4. After tilting up, it can be laid flat on the support plate 23-3; the front end of the support plate 23-3 is provided with a chassis dump bucket support member 22-2 for supporting the A mechanism to be laid flat on the support plate 23-3, and a positioning column 22-3 is provided at the lower rear end for positioning and supporting the A mechanism when it is set vertically.

The guide plate 19 is rotated to realize the rotation of the two rectangular frames 7, and the dump bucket connecting fixing member 12 is connected to the chassis dump bucket connecting member of the vehicle body.

[0038] A pair of guide shafts 3 are fixed on the above-mentioned nylon wheel bracket, the other end of the guide shaft 3 is suspended, and the side is fixed to the rectangular frame 7 by bolts. A guide cylinder 5 is arranged on the guide shaft 3. The guide shaft and the guide cylinder ensure that the oil cylinder moves up and down along the same trajectory to avoid shaking.

[0039] A fixed frame 17 is arranged on the support frame 20, and a translation cylinder 18 is arranged on the guide plate 19. The telescopic end of the translation cylinder 18 is connected to the fixed frame 17.

There are two fixed frames 17 and two translation cylinders 18, which are arranged to move in opposite directions.

[0040] The lifting cylinder 2 is disposed in the middle of a pair of guide shafts 3 .

[0041] The working process of this utility model:

[0042] Lift and Release: The rammer is lifted to a predetermined height by a hydraulic cylinder, and when the rammer reaches the predetermined height, it will be released.

[0043] Free fall: After release, the rammer falls freely under the action of gravity. During this process, the rammer gains kinetic energy and prepares for the subsequent micro-cracking action.

[0044] Tamping action: When the rammer contacts the ground or material, it converts the previously accumulated kinetic energy into impact force, causing micro-cracks in the ground.

[0045] The structure of the utility model is connected to the chassis of the vehicle body through a chassis dump bucket connecting piece, and is connected to the dump cylinder fixing piece through a dump cylinder arranged behind the head, so as to realize a 90° dumping of the A mechanism, reduce the speed, and facilitate transportation.

[0046] During the operation, the rammer micro-cracks the road surface with precise impact force, effectively breaking up the road surface material. Combined with other mixtures, it can improve the structural performance of the road surface, increase the overall strength and flatness, and reduce problems such as cracks and settlement.

[0047] Microcracking vehicles are widely used. They can be used not only for the maintenance and renovation of urban roads, but also for highways, airport runways, parking lots and other places. Whether it is a new road or an old road reconstruction, it can improve the service life of the road surface and driving comfort. Compared with traditional road repair methods, this technology has a short construction period and can quickly restore the function of the road surface. At the same time, due to the use of microcracking treatment, a lot of excavation and filling work is reduced, construction noise and dust pollution are reduced, and it is more in line with modern urban environmental protection requirements.

[0048] In general, the micro-crack vehicle provides a new solution for road maintenance and reconstruction with its high efficiency, flexibility and environmental protection. With the continuous development and application promotion of technology, it is believed that it will play a more important role in future road projects and provide a safer and more comfortable environment for people's travel.

[0049] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
