[0030] Pavement concrete crushing equipment is currently an effective construction equipment in gravel construction scenarios. Pavement concrete crushing equipment can crush the damaged parts of the road surface by crushing the cement pavement. After crushing, it can be used as the pavement subbase. The base layer can be added and asphalt concrete can be spread to form a new pavement structure bearing layer, which not only improves the construction efficiency but also reduces the construction cost, and can make full use of the original roadbed.
[0031] The road crushing equipment in the related art has the technical problem of easily destroying the roadbed and thus affecting the construction quality.
[0032] Please refer to Figure 1This embodiment provides a road crushing device 100, which can effectively improve the above-mentioned technical problems, avoid damaging the roadbed, ensure the safety of construction, and guarantee the construction quality.
[0033] Please refer to Figure 1 The road crushing equipment 100 includes a power part 10, a resonance crushing part 20 and a buffer part 30. The resonance crushing part 20 is connected to the power part 10. The resonance crushing part 20 is used to crush the old cement board. The buffer part 30 is arranged at the bottom of the resonance crushing part 20 and is used to buffer the resonance crushing part 20.
[0034] Specifically, the road crushing equipment in the prior art generally reserves a 25cm-40cm edge for the construction road surface during use. It is precisely because of the reserved edge that the road crushing equipment cannot perform all-round crushing when crushing. At the same time, the impact force of the road crushing equipment is too large, which will destroy the original roadbed and affect the construction quality. In order to solve this technical problem, when the road crushing equipment 100 provided in this embodiment is in use, the power part 10 can drive the resonance crushing part 20 to crush the old cement board. The old cement board can generate resonance under the action of the resonance crushing part 20, so that the concrete of the old cement board is broken into a large number of stone particle layers. A large number of stone particle layers will be embedded and squeezed together, thereby evenly dispersing the force. At the same time, a buffer part 30 is set at the bottom of the resonance crushing part 20. The buffer part 30 can prevent the roadbed at the bottom of the old cement board from being destroyed, thereby affecting the construction quality.
[0035] It should be noted that the resonant crushed stone element 20 in this embodiment crushes the old cement board under the drive of the power element 10, and the old cement board will be broken into cement concrete crushed stone particles layer with the upper layer interlocked with each other and the lower layer interlocked with each other. The crushed stones are adjacent and complementary in shape and have a small particle size, which can form a stable structure of mutual interlocking, so that the force of the resonant crushed stone element 20 can be evenly carried and evenly dispersed, reducing the impact on the original roadbed.
[0036] In this embodiment, the buffer 30 includes a base 31 and a buffer layer 32, the base 31 and the buffer layer 32 are in contact, and the buffer layer 32 is arranged at the bottom of the resonant gravel 20. The base 31 is placed on a stable road surface, and the resonant gravel 20 can be placed on the base 31 when not working. The buffer layer 32 is attached to the bottom of the resonant gravel 20, and can achieve a buffering effect when the resonant gravel 20 is placed on the base 31, thereby protecting the resonant gravel 20.
[0037] In this embodiment, the buffer layer 32 is an elastic layer. Specifically, the elastic layer is a rubber pad. The thickness of the rubber pad ranges from 2 cm to 4 cm. In this embodiment, the thickness of the rubber pad is 4 cm. In other embodiments, the thickness of the rubber pad can be 2 cm, 3 cm, or 3.2 cm, etc., which is not specifically limited here.
[0038] It should also be noted that the resonant stone crushing member 20 includes a resonator 21, an elastic member 22 and a hammer head 23, the elastic member 22 is connected to the resonator 21, the resonator 21 is connected to the power member 10, the resonator 21 is connected to the hammer head 23, and the buffer member 30 is disposed on the hammer head 23. Specifically, the resonator 21 is driven by the power member 10, and can drive the hammer head 23 to generate high-frequency vibration, so that the hammer head 23 hammers downward under vibration, thereby crushing the old cement board.
[0039] In this embodiment, the vibration frequency of the resonator 21 ranges from 40 Hz to 45 Hz. Specifically, the vibration frequency of the resonator 21 is 44 Hz. In other embodiments, the vibration frequency of the resonator 21 may also be 40 Hz, 42 Hz or 45 Hz, which is not specifically limited here.
[0040] In this embodiment, the amplitude of the resonator 21 ranges from 3m to 4m. Specifically, the amplitude of the resonator 21 is 3m. In other embodiments, the amplitude of the resonator 21 may also be 3.5m, 3.8m or 4m, which is not specifically limited here.
[0041] It should be noted that the depth of the downward crushing of the hammer head 23 can be controlled by adjusting the vibration frequency and amplitude of the resonator 21. The hammer head 23 can crush downward at the moment when the resonator 21 drives the hammer head 23 to resonate. Since the vertical downward impact force of the hammer head 23 is small, the bottom of the old cement board is not made of concrete. Therefore, when the hammer head 23 crushes downward, the structure under the old cement board will not resonate, thereby avoiding the impact on the roadbed and causing no damage to the pipeline facilities under the roadbed.
[0042] At the same time, since the resonator 21 resonates in a high-frequency and low-amplitude manner, its vibration wave decays quickly and has a small transmission range, and generally does not affect structures 2m-3m away from the construction site. Therefore, there is no need to reserve a wider edge for the construction road, and the old cement slabs can be better resonated and crushed, avoiding the problem of incomplete local vibration and crushing.
[0043] In addition, since the resonator 21 resonates in a high-frequency and low-amplitude manner, the noise generated by the hammer head 23 and the old cement board due to crushing is also relatively small, which can reduce the noise impact on surrounding residents.
[0044] In this embodiment, the resonator 21 drives the hammer head 23 to perform crushing to a depth of up to 220 m.
[0045] Specifically, the elastic member 22 is a spring, and the spring is sleeved on the resonator 21. In other embodiments, the elastic member 22 may also be a spring sheet, which is not specifically limited here.
[0046] In addition, the power unit 10 includes an engine and an oil tank, the engine and the oil tank are connected, and the engine and the resonance stone crushing unit 20 are connected. The oil tank can provide oil to the engine so that the engine can start normally, thereby driving the resonance stone crushing unit 20 to crush stones.
[0047] In this embodiment, in order to facilitate the operation and transfer of the resonance crushed stone pieces 20 , the road crushing equipment 100 provided in this embodiment further includes a handrail 40 , which is connected to the resonance crushed stone pieces 20 .
[0048] The road crushing equipment 100 provided in this embodiment has at least the following advantages:
[0049] The road crushing equipment in the prior art generally reserves a 25cm-40cm edge for the construction road surface during use. It is precisely because of the reserved edge that the road crushing equipment cannot perform all-round crushing when crushing. At the same time, the impact force of the road crushing equipment is too large, which will destroy the original roadbed and affect the construction quality. In order to solve this technical problem, when the road crushing equipment 100 provided in this embodiment is in use, the power part 10 can drive the resonance crushing part 20 to crush the old cement board. The old cement board can generate resonance under the action of the resonance crushing part 20, so that the concrete of the old cement board is broken into a large number of stone particle layers. A large number of stone particle layers will be embedded and squeezed together, thereby evenly dispersing the force. At the same time, a buffer part 30 is set at the bottom of the resonance crushing part 20. The buffer part 30 can prevent the roadbed at the bottom of the old cement board from being destroyed, thereby affecting the construction quality.
[0050] The road crushing equipment 100 in this embodiment can control the crushing depth of the hammer head 23 by adjusting the vibration frequency and amplitude of the resonator 21. The hammer head 23 can crush downwards at the moment when the resonator 21 drives the hammer head 23 to resonate. Since the vertical downward impact force of the hammer head 23 is small, the lower part of the old cement board is not made of concrete. Therefore, when the hammer head 23 crushes downwards, the structure under the old cement board will not resonate, thereby avoiding impact on the roadbed and not causing damage to the pipeline facilities under the roadbed.
[0051] In summary, the embodiment of the utility model provides a road crushing device 100, which includes a power part 10, a resonance crushing part 20 and a buffer part 30. The resonance crushing part 20 is connected to the power part 10, the resonance crushing part 20 is used to crush the old cement board, and the buffer part 30 is arranged at the bottom of the resonance crushing part 20. The buffer part 30 is used to buffer the resonance crushing part 20. When the road crushing device 100 is in use, the power part 10 can drive the resonance crushing part 20 to crush the old cement board. The old cement board can generate resonance under the action of the resonance crushing part 20, so that the concrete of the old cement board is broken into a large number of stone particle layers. The large number of stone particle layers will be embedded and squeezed together, so as to evenly disperse the force. At the same time, the buffer part 30 is arranged at the bottom of the resonance crushing part 20. The buffer part 30 can prevent the roadbed at the bottom of the old cement board from being damaged, thereby affecting the construction quality.
[0052] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
