Description

Technical Field

[0001] This invention relates to the field of road construction, specifically to a green and environmentally friendly road construction device and its construction method. Background Technology

[0002] During road construction, road cutting equipment is used to cut expansion joints in concrete pavement. This helps to distribute the pressure generated by external forces such as thermal expansion and contraction and earthquakes, reducing road cracks and damage.

[0003] However, existing road cutting devices expose the cutting blade to the outside during use, resulting in loud noise and dust, which is not environmentally friendly. Although some road cutting devices are equipped with dust collection and water spray cooling structures, the dust dispersion makes the dust collection effect poor. Moreover, when spraying water, it is not convenient to automatically adjust the width of the water spray according to the cutting depth of the cutting blade, which easily leads to water waste and is not environmentally friendly. Summary of the Invention

[0004] To address the problems in the existing technology, this invention provides a green and environmentally friendly road construction device and its construction method.

A second motor is fixedly connected to the top of the box, and the output end of the second motor is fixed to the upper end of the threaded rod.

[0007] The first reset mechanism includes two symmetrically arranged first T-shaped guide rods fixedly connected to the top of the sound insulation panel, and a U-shaped plate is sleeved on the side wall of the first T-shaped guide rod. The U-shaped plate is fixed to the bottom of the box, and a first spring is sleeved on the side wall of the first T-shaped guide rod.

[0008] The first pushing mechanism includes a fixed box that is fixedly inserted into the side wall of the exhaust pipe, and a rotating fan is rotatably connected inside the fixed box via a rotating rod. The top of the sound insulation plate is connected to a first pushing plate via a telescopic mechanism, and the first pushing plate includes a first inclined surface. A fixed ring is fixedly sleeved on the side wall of the rotating rod, and a plurality of arrayed metal balls are connected to the side wall of the fixed ring via a second reset mechanism, and the metal balls slide on the first inclined surface.

[0009] The telescopic mechanism includes two symmetrically arranged second T-shaped guide rods fixedly connected to the top of the sound insulation panel, and a connecting block is sleeved on the side wall of the second T-shaped guide rod. The connecting block is fixed to the side wall of the first push plate, and a second spring is sleeved on the side wall of the second T-shaped guide rod.

[0010] The second reset mechanism includes multiple arrayed sleeves fixedly connected to the side wall of the fixed ring, and a sliding disk is slidably connected inside the sleeve. A sleeve rod is fixedly connected to the end of the sliding disk, and the other end of the sleeve rod is fixed to the side wall of the metal ball. A third spring is sleeved on the side wall of the sleeve rod.

[0011] The adjustment mechanism includes two symmetrically arranged sealing plates that are slidably connected to the side walls of each hollow tube, and a connecting plate is fixedly connected to the side wall of the sealing plate. Two symmetrically arranged third T-shaped guide rods are inserted into the side wall of the connecting plate, and one end of the third T-shaped guide rod is fixed to the side wall of the hollow tube. A fourth spring is sleeved on the side wall of the third T-shaped guide rod, and the movement of the sealing plate is driven by a second pushing mechanism.

[0012] The second pushing mechanism includes two symmetrically arranged second pushing plates fixedly connected to the side wall of the movable plate, and the bottom of the second pushing plate is provided with a second inclined surface. The top of each of the sealing plates is fixedly connected with a pushing rod, and the upper end of the pushing rod slides on the second inclined surface.

[0013] A label plate is fixedly connected to the side wall of the movable plate. The upper end of the label plate extends through the top of the box, and the side wall of the label plate is marked with scale markings.

[0014] A green and environmentally friendly road construction method, utilizing the green and environmentally friendly road construction device described above, is characterized by comprising the following steps:

[0015] S1: When it is necessary to cut the road surface, start the first motor. The rotation of the first motor drives the rotating shaft and the cutting blade to rotate. At the same time, start the second motor. The rotation of the second motor drives the threaded rod to rotate, which in turn drives the moving plate and the cutting blade to move downward. Furthermore, by pushing the box to move, the road surface is cut. Meanwhile, the cutting depth can be controlled by observing the scale markings on the marking plate.

[0016] S2: Start the exhaust fan to perform air extraction. The dust collection hood can absorb the dust after cutting, and the dust will be filtered and collected in the filter box through the exhaust pipe, making it more green and environmentally friendly.

[0017] S3: When air enters the fixed box, it impacts the rotating fan, causing it to rotate. The rotation of the fan drives the rotating rod and the fixed ring to rotate, causing the metal ball to move away from the fixed ring under the action of centrifugal force. At the same time, the third spring is compressed, thus abutting against the first inclined plane and sliding on its surface, thereby pushing the first push plate to move downward. This, in turn, drives the sound insulation plate downward through the telescopic mechanism. When the bottom of the sound insulation plate contacts the road surface, the second spring is gradually compressed, thus enclosing the cutting blade inside through the box and the sound insulation plate. This not only reduces noise during construction but also prevents dust from escaping, resulting in better dust collection and a more environmentally friendly process.

[0018] S4: When cutting, turn on the water pump in the water tank so that the cooling water in the water tank enters the hollow pipe through the water supply pipe and is sprayed onto the interface between the cutting blade and the road surface through the water spray hole. This not only cools down the cutting blade, thereby improving cutting efficiency and reducing noise, but also reduces dust and prevents dust from being raised, making it more environmentally friendly.

[0019] S5: During cutting, the lifting mechanism drives the moving plate and cutting blade to gradually move downwards and cut into the road surface. When the moving plate moves downwards, it drives the second pushing plate to move downwards simultaneously, causing the upper end of the pushing rod to abut against the second inclined plane and slide on its surface. This pushes the two sealing plates away from each other. At the same time, the fourth spring is compressed, thus exposing more water spray holes for water spraying. This allows the width of the water spray to gradually increase, so that the width of the water spray can be automatically adjusted as the cutting blade gradually cuts in, ensuring the cooling effect while avoiding the waste of cooling water, making it more environmentally friendly.

[0020] The beneficial effects of this invention are:

[0021] (1) The green and environmentally friendly road construction device and its construction method of the present invention, by setting a first pushing mechanism, etc., when it is necessary to cut the road surface, the first motor is started. The rotation of the first motor drives the rotation of the rotating shaft and the cutting blade. At the same time, the second motor is started. The rotation of the second motor drives the rotation of the threaded rod, which in turn drives the moving plate and the cutting blade to move downward. And, by pushing the box to move, the road surface is cut. At the same time, the cutting depth can be controlled by observing the scale markings on the marking plate. At the same time, the exhaust fan is started to perform air extraction operation. The dust collection hood can absorb the dust after cutting and enter the filter box for filtration through the exhaust pipe. The collection process is more environmentally friendly. When air enters the fixed box, it impacts the rotating fan, causing it to rotate. The rotation of the fan drives the rotating rod and the fixed ring to rotate, causing the metal ball to move away from the fixed ring under centrifugal force. At the same time, the third spring is compressed, thus abutting against the first inclined plane and sliding on its surface, thereby pushing the first push plate downward. This, in turn, drives the sound insulation plate downward through the telescopic mechanism. When the bottom of the sound insulation plate contacts the road surface, the second spring is gradually compressed, thus enclosing the cutting blade inside through the box and the sound insulation plate. This not only reduces noise during construction but also prevents dust from escaping, resulting in better dust collection and a more environmentally friendly process.

[0022] (2) The green and environmentally friendly road construction device and its construction method described in this invention, by setting a second pushing mechanism, etc., when cutting, the water pump in the water storage tank is turned on, so that the cooling water in the water storage tank enters the hollow pipe through the water supply pipe and is sprayed on the joint surface between the cutting blade and the road surface through the spray nozzle. This not only cools the cutting blade, thereby improving the cutting efficiency and reducing noise, but also reduces dust and prevents dust from being raised, making it more environmentally friendly. At the same time, when cutting, the lifting mechanism drives the moving plate and the cutting blade to move downward and cut into the road surface. When the moving plate moves downward, it drives the second pushing plate to move downward synchronously, so that the upper end of the pushing rod abuts against the second inclined surface and slides on its surface, thereby pushing the two sealing plates to move away from each other. At the same time, the fourth spring is compressed, thereby exposing more spray nozzles for water spraying, so that the width of the water spray gradually increases. Thus, when cutting, as the cutting blade gradually cuts in, the width of the water spray can be automatically adjusted, ensuring the cooling effect while avoiding the waste of cooling water, making it more environmentally friendly.

[0036] like Figures 1-9As shown, a green and environmentally friendly road construction device of the present invention includes a box body 1, and a plurality of symmetrically arranged movable wheels 10 are fixedly connected to the bottom of the box body 1. A strip-shaped opening 11 is opened at the bottom of the box body 1, and a movable plate 12 is connected to the box body 1 through a lifting mechanism. An installation groove 13 is opened at the top of the movable plate 12, and a cutting blade 15 is rotatably connected to the installation groove 13 through a rotating shaft 14. A first motor 16 is fixedly connected to the side wall of the movable plate 12, and the output end of the first motor 16 is fixed to one end of the rotating shaft 14. An annular groove 18 is opened at the bottom of the box body 1, and a cutting blade 15 is inserted into the annular groove 18. A ring-shaped sound insulation panel 19 is connected to the bottom of the housing 1 via a first reset mechanism. An air inlet 29 is provided on the side wall of the sound insulation panel 19, and a filter 30 is fixedly connected inside the air inlet 29. The filter 30 ensures normal air intake during dust extraction. The sound insulation panel 19 is moved by a first push mechanism. A filter box 22 is fixedly connected to the side wall of the housing 1. A discharge valve 24 is fixedly connected to the bottom of the filter box 22, and an exhaust fan 23 is fixedly connected to the top of the filter box 22. An exhaust pipe 20 is fixedly connected to the upper end of the exhaust fan 23. The other end of the casing 1 is fixedly connected to a dust collection hood 21 through the bottom of the casing 1. Two symmetrically arranged fixing plates 25 are fixedly connected to the bottom of the casing 1, and two inclined hollow tubes 26 are fixedly connected to the side walls of the fixing plates 25. Multiple arrayed water spray holes 17 are opened on the side walls of the hollow tubes 26, and two symmetrically arranged water storage tanks 27 are fixedly connected to the side walls of the casing 1. A water pump is installed inside the water storage tank 27 (this is well-known technology in this field and will not be described in detail here). A water supply pipe 28 is fixedly connected to the bottom of the water storage tank 27, and the other end of the water supply pipe 28 penetrates the side wall of the fixing plate 25 and connects to... The hollow tube 26 is fixed to the side wall, which is equipped with an adjustment mechanism for automatically adjusting the water spray width. During cutting, the sound insulation plate 19 can be automatically moved downward and contacted with the road surface, thereby enclosing the cutting blade 15 inside the box 1 and the sound insulation plate 19. This not only reduces noise during construction but also prevents dust from escaping, resulting in better dust collection and a more environmentally friendly process. Furthermore, during cutting, the width of the water spray can be automatically adjusted according to the cutting depth of the cutting blade 15, ensuring cooling effect while avoiding waste of cooling water, making it even more environmentally friendly.

[0037] The lifting mechanism includes a fixed rod 201 fixedly connected between the top and bottom of the housing 1, and a movable plate 12 sleeved on the side wall of the fixed rod 201. A threaded rod 202 is rotatably connected between the top and bottom of the housing 1, and the movable plate 12 is threadedly connected to the side wall of the threaded rod 202. A second motor 203 is fixedly connected to the top of the housing 1, and the output end of the second motor 203 is fixed to the upper end of the threaded rod 202. When the second motor 203 is started, the rotation of the second motor 203 drives the rotation of the threaded rod 202, thereby driving the movable plate 12 and the cutting blade 15 to lift.

[0038] The first reset mechanism includes two symmetrically arranged first T-shaped guide rods 302 fixedly connected to the top of the sound insulation panel 19, and a U-shaped plate 301 is sleeved on the side wall of the first T-shaped guide rod 302. The U-shaped plate 301 is fixed to the bottom of the box 1, and a first spring 303 is sleeved on the side wall of the first T-shaped guide rod 302, which plays a guiding and reset role for the movement of the sound insulation panel 19.

[0039] The first pushing mechanism includes a fixed box 401 fixedly inserted into the side wall of the exhaust pipe 20, and a rotating fan 403 is rotatably connected to the fixed box 401 via a rotating rod 402. The top of the sound insulation plate 19 is connected to a first pushing plate 404 via a telescopic mechanism, and the first pushing plate 404 includes a first inclined surface 405. A fixing ring 407 is fixedly sleeved on the side wall of the rotating rod 402, and a plurality of arrayed metal balls 406 are connected to the side wall of the fixing ring 407 via a second reset mechanism. The metal balls 406 are arranged in a first inclined surface 405. Sliding on surface 405, when air enters the fixed box 401, it impacts the rotating fan 403, causing it to rotate. The rotation of the rotating fan 403 drives the rotation of the rotating rod 402 and the fixed ring 407, causing the metal ball 406 to move away from the fixed ring 407 under the action of centrifugal force. At the same time, the third spring 604 is compressed, thus abutting against the first inclined surface 405 and sliding on its surface, thereby pushing the first push plate 404 to move downward, and then driving the sound insulation plate 19 to move downward through the telescopic mechanism.

[0040] The telescopic mechanism includes two symmetrically arranged second T-shaped guide rods 501 fixedly connected to the top of the sound insulation plate 19, and a connecting block 502 is sleeved on the side wall of the second T-shaped guide rod 501. The connecting block 502 is fixed to the side wall of the first push plate 404, and a second spring 503 is sleeved on the side wall of the second T-shaped guide rod 501. When the bottom of the sound insulation plate 19 contacts the road surface, the second spring 503 is gradually compressed to avoid excessive pressure on the road surface.

[0041] The second reset mechanism includes multiple arrayed sleeves 601 fixedly connected to the side wall of the fixed ring 407, and a sliding disk 602 slidably connected inside the sleeve 601. A sleeve rod 603 is fixedly connected to the end of the sliding disk 602, and the other end of the sleeve rod 603 is fixed to the side wall of the metal ball 406. A third spring 604 is sleeved on the side wall of the sleeve rod 603, which guides and resets the movement of the metal ball 406.

[0042] The adjustment mechanism includes two symmetrically arranged sealing plates 701 slidably connected to the side walls of each hollow tube 26, and a connecting plate 703 is fixedly connected to the side wall of the sealing plate 701. Two symmetrically arranged third T-shaped guide rods 702 are inserted into the side wall of the connecting plate 703, and one end of the third T-shaped guide rod 702 is fixed to the side wall of the hollow tube 26. A fourth spring 704 is sleeved on the side wall of the third T-shaped guide rod 702. The movement of the sealing plate 701 is driven by a second pushing mechanism. During cutting, the water pump in the water storage tank 27 is turned on, so that the cooling water in the water storage tank 27 enters the hollow tube 26 through the water supply pipe 28 and is sprayed onto the cutting blade 15 and the cutting surface through the water spray hole 17. At the interface of the cutting blades, not only can the cutting blade 15 be cooled, thereby improving cutting efficiency and reducing noise, but dust can also be reduced to prevent dust from being stirred up, making it more environmentally friendly. At the same time, when the moving plate 12 moves downward during cutting, the two sealing plates 701 are pushed away from each other by the second pushing mechanism. Meanwhile, the fourth spring 704 is compressed, thereby exposing more water spray holes 17 for water spraying, so that the width of the water spray gradually increases. Thus, as the cutting blade 15 gradually cuts in during cutting, the width of the water spray can be automatically adjusted to ensure the cooling effect while avoiding the waste of cooling water, making it more environmentally friendly.

[0043] The second pushing mechanism includes two symmetrically arranged second pushing plates 802 fixedly connected to the side wall of the moving plate 12, and a second inclined surface 803 is provided at the bottom of the second pushing plate 802. A pushing rod 801 is fixedly connected to the top of each sealing plate 701, and the upper end of the pushing rod 801 slides on the second inclined surface 803. When the moving plate 12 moves downward, it drives the second pushing plate 802 to move downward synchronously, and causes the upper end of the pushing rod 801 to abut against the second inclined surface 803 and slide on its surface, thereby pushing the two sealing plates 701 to move away from each other. At the same time, the fourth spring 704 is compressed.

[0044] A marker plate 901 is fixedly connected to the side wall of the movable plate 12. The upper end of the marker plate 901 extends through the top of the box 1, and the side wall of the marker plate 901 is provided with a scale mark 902 to facilitate control of the cutting depth of the cutting blade 15 on the road surface.

[0045] A green and environmentally friendly road construction method, utilizing the aforementioned green and environmentally friendly road construction device, includes the following steps:

[0046] S1: When it is necessary to cut the road surface, the first motor 16 is started. The rotation of the first motor 16 drives the rotation of the shaft 14 and the cutting blade 15. At the same time, the second motor 203 is started. The rotation of the second motor 203 drives the rotation of the threaded rod 202, which in turn drives the moving plate 12 and the cutting blade 15 to move downward. Furthermore, by pushing the box 1 to move, the road surface is cut. Meanwhile, the cutting depth can be controlled by observing the scale markings 902 on the marking plate 901.

[0047] S2: Start the exhaust fan 23 to perform air extraction. The dust collected by the dust collection hood 21 can absorb the dust after cutting, and the dust enters the filter box 22 through the exhaust pipe 20 for filtration and collection, which is more green and environmentally friendly.

[0048] S3: When air enters the fixed box 401, it impacts the rotating fan 403, causing it to rotate. The rotation of the rotating fan 403 drives the rotation of the rotating rod 402 and the fixed ring 407, causing the metal ball 406 to move away from the fixed ring 407 under the action of centrifugal force. At the same time, the third spring 604 is compressed, thus abutting against the first inclined surface 405 and sliding on its surface, thereby pushing the first push plate 404 to move downward, and then driving the sound insulation plate 19 to move downward through the telescopic mechanism. When the bottom of the sound insulation plate 19 contacts the road surface, the second spring 503 is gradually compressed, so that the cutting blade 15 can be sealed inside through the box 1 and the sound insulation plate 19. This not only reduces the noise during construction, but also prevents the dust from escaping, making the dust collection effect better and more environmentally friendly.

[0049] S4: When cutting, turn on the water pump in the water storage tank 27 so that the cooling water in the water storage tank 27 enters the hollow pipe 26 through the water supply pipe 28 and is sprayed onto the interface between the cutting blade 15 and the road surface through the water spray hole 17. This not only cools down the cutting blade 15, thereby improving cutting efficiency and reducing noise, but also reduces dust, preventing dust from being raised, making it more environmentally friendly.

[0050] S5: During cutting, the lifting mechanism drives the moving plate 12 and the cutting blade 15 to gradually move downwards and cut into the road surface. When the moving plate 12 moves downwards, it drives the second push plate 802 to move downwards simultaneously, causing the upper end of the push rod 801 to abut against the second inclined surface 803 and slide on its surface, thereby pushing the two sealing plates 701 to move away from each other. At the same time, the fourth spring 704 is compressed, thereby exposing more water spray holes 17 for water spraying, so that the width of the water spray gradually increases. Thus, during cutting, as the cutting blade 15 gradually cuts in, the width of the water spray can be automatically adjusted to ensure the cooling effect while avoiding the waste of cooling water, making it more environmentally friendly.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.

The upper end of the indicator plate (901) is set through the top of the box (1), and the side wall of the indicator plate (901) is provided with scale markings (902).

7. A green and environmentally friendly road construction method, utilizing a green and environmentally friendly road construction device as described in any one of claims 1-6, characterized in that: Includes the following steps: S1: When it is necessary to cut the road surface, start the first motor (16). The rotation of the first motor (16) drives the rotation of the shaft (14) and the cutting blade (15). At the same time, start the second motor (203). The rotation of the second motor (203) drives the rotation of the threaded rod (202), which in turn drives the moving plate (12) and the cutting blade (15) to move downward. And, by pushing the box (1) to move, the road surface is cut. At the same time, the cutting depth can be controlled by observing the scale markings (902) on the marking plate (901). S2: Start the exhaust fan (23) to perform the exhaust operation. The dust collected by the dust collection hood (21) can absorb the dust after cutting and enter the filter box (22) through the exhaust pipe (20) for filtration and collection. S3: When air enters the fixed box (401), it impacts the rotating fan (403) and causes it to rotate. The rotation of the rotating fan (403) drives the rotation of the rotating rod (402) and the fixed ring (407), causing the metal ball (406) to move away from the fixed ring (407) under the action of centrifugal force. At the same time, the third spring (604) is compressed, thus abutting against the first inclined plane (405) and sliding on its surface, thereby pushing the first push plate (404) to move downward, and then driving the sound insulation plate (19) to move downward through the telescopic mechanism. When the bottom of the sound insulation plate (19) contacts the road surface, the second spring (503) is gradually compressed, so that the cutting plate (15) can be sealed inside through the box (1) and the sound insulation plate (19). S4: When cutting, turn on the water pump in the water tank (27) so that the cooling water in the water tank (27) enters the hollow tube (26) through the water supply pipe (28) and is sprayed onto the interface between the cutting blade (15) and the road surface through the water spray hole (17); S5: During cutting, the lifting mechanism drives the moving plate (12) and the cutting blade (15) to move downwards and cut into the road surface. When the moving plate (12) moves downwards, it drives the second push plate (802) to move downwards synchronously, and the upper end of the push rod (801) abuts against the second inclined plane (803) and slides on its surface, thereby pushing the two sealing plates (701) to move away from each other. At the same time, the fourth spring (704) is compressed, thereby exposing more water spray holes (17) for water spraying, so that the width of the water spray gradually increases.
