Description

Technical Field

[0001] This invention relates to the field of roadbed paving technology, specifically to a roadbed paving device and construction process for municipal road construction. Background Technology

[0002] The roadbed is the foundation of the track or road surface, and it is an earthwork structure formed by excavation or filling.

[0003] In the existing technology, with the development of cities, the demand for municipal roads is constantly increasing. Pavers are pipe equipment for road construction. Pavers are used to spread the mixed material evenly on the prepared roadbed or base layer. Through preliminary compaction and shaping, a paving layer with a certain width, thickness and shape is formed. In order to better adapt to different paving thicknesses, a cylinder is generally set on the auger distributor to adjust its height with the ground.

[0004] However, existing pavers adjust the height of the auger distributor using cylinders, requiring a dedicated power mechanism that is complex and costly. Therefore, this invention proposes a roadbed paving device and construction process for municipal road construction to solve the aforementioned problems. Summary of the Invention

[0010] Preferably, the lifting rod has an oil groove inside away from the lifting arm, the lifting rod has a sliding plate groove on the outer surface of the oil groove, the inner wall side surface of the sliding plate groove has a second sliding groove, the bottom surface of the inner wall of the sliding plate groove near the annular groove has a through hole, the through hole penetrates the oil groove, the through hole corresponds to the connecting hole, and an oil pipe is fixed on the inner wall of the connecting hole.

[0011] Preferably, the inner wall of the sliding plate groove is provided with a sliding plate, and a pushing block is fixed on the lower surface of the sliding plate. The sliding plate corresponds to and is engaged with the second sliding groove, forming a movable connection. The annular groove has a storage groove inside, and the storage groove has an opening near the end. The bottom of the inner wall of the opening has a toothed block groove, and the annular groove has a gear groove in the middle. The gear groove penetrates to the oil groove, and the toothed block groove is connected to the gear groove.

[0012] Preferably, the inner wall of the storage slot is provided with a baffle, a limiting block is fixed on the upper surface of the baffle, the limiting block corresponds to the limiting groove, a toothed block is fixed on the bottom surface of the baffle, the toothed block corresponds to the toothed block groove, and a spring is fixed on the inner wall of the storage slot below the baffle.

[0013] Preferably, a guide rod is rotatably connected to the inner wall side surface of the gear groove, and a stirring blade is fixed to the outer surface of the guide rod. The stirring blade is located on the outer surface of the guide rod inside the oil groove. A transmission tooth groove is formed on the outer surface of the end of the guide rod near the annular groove, and a gear is rotatably connected to the outer surface of the transmission tooth groove.

[0014] Preferably, the inner wall of the gear has an internal tooth groove, a rotating shaft is fixed to the inner side surface of the gear, and a transmission gear is rotatably connected to the outer surface of the rotating shaft. The transmission gear, the transmission tooth groove and the internal tooth groove correspond to each other, and the tooth block corresponds to the outer surface of the gear.

[0015] A construction process for a roadbed paving device for municipal road construction, as described above, includes the following steps: Step 1: Lifting. The lifting arm is a special adjustment tool for adjusting the height of the vibrator off the ground. When it is necessary to adjust the height of the auger distributor body off the ground, drive the lifting arm so that the lifting hole corresponds to the lifting rod. At this time, hold the handle collar and pull it to lock the lifting rod into the lifting hole. Then rotate the handle collar. Because the edges of the limiting groove and the limiting block are curved, rotating the handle collar can squeeze the limiting block and make it retract into the receiving groove. When the handle collar rotates to the point where there is no gap between it and the connection, then move the limiting groove and the limiting block into the receiving groove. The position blocks are aligned and locked in place. Under the restriction of the limit blocks and without the use of a large external force to pull, the handle collar will not rotate, so that the lifting rod is locked and fixed in the lifting hole. Since the lifting hole and the lifting rod are movably connected, there is no restriction during lifting. At this time, the main body of the auger distributor can be separated from the main body of the paver by tools, and the lifting arm can be used to drive the main body of the auger distributor to lift. This lifting method does not require an external power mechanism, thus reducing the cost of adjusting the height of the main body of the auger distributor. Step 2: Lubrication. When the handle collar is pulled from the positioning groove on the side away from the lifting arm to another set of positioning grooves, the sliding plate will move with the lifting rod. Since the length of the sliding plate is less than the distance the lifting rod moves, the fixed block in the lifting rod groove near the lifting arm will block the sliding plate by pushing the block, causing the sliding plate to move in the sliding plate groove. The movement of the sliding plate will expose the through hole. When the lifting rod is engaged with the lifting hole, the through hole is fully exposed. Since there is lubricating oil in the oil groove, when the through hole is exposed, the lubricating oil will flow into the connecting hole through the through hole. The lubricating oil in the connecting hole will soak into the sponge block. When the sponge block has enough lubricating oil, the sponge block drips oil into the oil pipe fixed in the connecting hole. The oil pipe will transport the lubricating oil to the rotating part of the screw distributor body to prevent the temperature from rising due to high friction when the screw distributor body rotates. Step 3: Stirring. Rotating the handle collar will squeeze the limiting block into the receiving groove. The downward movement of the limiting block will cause the toothed block to move downward. Since the toothed block corresponds to the tooth groove on the outer surface of the gear, the movement of the toothed block will drive the gear to rotate. The rotation of the gear will drive the transmission gear to rotate. The rotation of the transmission gear will drive the guide rod to rotate through the transmission tooth groove. The rotation of the guide rod will drive the stirring blade to rotate. Since the diameter of the transmission gear and the guide rod is much smaller than the diameter of the gear, the limiting block will rotate the gear by 30 degrees through the toothed block. The rotation of the gear will drive the guide rod to rotate one revolution through the transmission gear. At the same time, since more than one toothed block moves, it can satisfy the stirring blade's stirring of the lubricating oil in the oil tank, prevent the lubricating oil from accumulating in the oil tank, and facilitate the flow of lubricating oil into the through hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are: Drive the lifting arm to align the lifting hole with the lifting rod. Then, hold the handle collar and pull to engage the lifting rod into the lifting hole. Rotate the handle collar to compress the limiting block and retract it into the receiving groove. When the handle collar rotates to the point where there is no gap between it and the connection, align the limiting groove with the limiting block and engage it. Under the constraint of the limiting block and without applying significant external force, the handle collar will not rotate, thus securing the lifting rod in the lifting hole. Use the lifting arm to lift the main body of the screw distributor. This lifting method does not require an external power mechanism, reducing the cost of adjusting the height of the screw distributor. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 13 The present invention provides a technical solution: a roadbed paving device and construction process for municipal road construction.

[0021] Example 1: A roadbed paving device for municipal road construction includes: a lifting arm 3 fixed to the side surface of the paver body 1; a lifting hole 2 opened on the inner surface of the lifting arm 3, so that the lifting rod 11 is fixed in the lifting hole 2; and since the lifting hole 2 and the lifting rod 11 are movably connected, there is no restriction during lifting. The lifting arm 3 is used to drive the auger distributor body 5 to be lifted. This lifting method does not require an external power mechanism, thus reducing the cost of adjusting the height of the auger distributor body 5. A vibrator 4 is fixed to the end of the lifting arm 3. The lifting arm 3 is a special adjustment tool for adjusting the height of the vibrator 4 off the ground. The auger distributor body 5 is fixed to the surface of the paver body 1 behind the vibrator 4. Before using the lifting arm 3 to lift the auger distributor body 5, it needs to be separated from the paver body 1 by a tool.

[0022] A connecting block 7 is fixed to the surface of the fixed arm 6. A lifting rod 11 is inserted inside the connecting block 7. A handle collar 14 is sleeved on the outer surface of the middle part of the lifting rod 11. Rotating the handle collar 14 can squeeze the limiting block 32 and make it retract into the storage groove 24. When the handle collar 14 rotates to the point where it is no longer in contact with the connecting gap 10, the limiting groove 19 and the limiting block 32 are then aligned and locked. Under the restriction of the limiting block 32, and without the use of a large external force to pull, the handle collar 14 will not rotate. The diameter of the lifting rod 11 is equal to the diameter of the lifting hole 2. Since the lifting hole 2 and the lifting rod 11 are movably connected, they are not restricted during lifting.

[0023] In Example 2, based on Example 1, in order to reduce the cost of adjusting the height of the spiral distributor body 5, the fixed arm 6 is fixed to the side surface of the spiral distributor body 5. The connecting block 7 has a lifting rod groove 16 inside. A slider 15 is fixed to the inner wall side surface of the lifting rod groove 16. The slider 15 is locked in the first sliding groove 22 to prevent the rotating handle collar 14 from driving the lifting rod 11 to rotate. A fixing block 17 is fixed to the bottom surface of the inner wall of the lifting rod groove 16. The fixing block 17 will hold the pushing block 20 to block the movement of the sliding plate 13. A connecting hole 18 is opened on the bottom surface of the inner wall of the lifting rod groove 16. A sponge block 12 is fixed to the inner wall of the connecting hole 18. The lubricating oil in the connecting hole 18 will be immersed in the sponge block 12. When the sponge block 12 has enough lubricating oil, the sponge block 12 drips oil to the oil pipe 8 fixed in the connecting hole 18. The connecting hole 18 is located on the side of the fixing block 17.

[0024] The outer surface of the connecting block 7 is provided with a positioning groove 9. There are two sets of positioning grooves 9, which are symmetrically distributed. The outer surface of the connecting block 7 between the two sets of positioning grooves 9 is provided with a connecting gap 10. The positioning groove 9 and the connecting gap 10 penetrate into the lifting rod groove 16. When the handle collar 14 is pulled from the positioning groove 9 on the side away from the lifting arm 3 to the other set of positioning grooves 9, the lifting rod 11 can be locked into the lifting hole 2. The inner wall of the lifting rod groove 16 is provided with the lifting rod 11, and the outer surface of the middle of the lifting rod 11 is provided with an annular groove 21.

[0025] A grip ring 14 is fitted onto the inner wall surface of the annular groove 21. The grip ring 14 corresponds to and is engaged with the positioning groove 9. A limiting groove 19 is formed on the inner surface of the grip ring 14. Since the edges of the limiting groove 19 and the limiting block 32 are curved, rotating the grip ring 14 can squeeze the limiting block 32 and make it retract into the storage groove 24. A first sliding groove 22 is formed on the outer surface of the lifting rod 11. Multiple sets of first sliding grooves 22 are formed and distributed circumferentially on the outer surface of the lifting rod 11. The slider 15 corresponds to the first sliding groove 22 and is engaged in the first sliding groove 22. The two are movably connected. The slider 15 is engaged in the first sliding groove 22 to prevent rotating the grip ring 14 from causing the lifting rod 11 to rotate.

[0026] An oil groove 28 is provided inside the lifting rod 11 away from the lifting arm 3. A sliding plate groove 29 is provided on the outer surface of the lifting rod 11 located in the oil groove 28. A second sliding groove 30 is provided on the inner side surface of the sliding plate groove 29. A through hole 31 is provided on the bottom surface of the inner wall of the sliding plate groove 29 near the annular groove 21. The through hole 31 penetrates the oil groove 28 and corresponds to the connecting hole 18. An oil pipe 8 is fixed on the inner wall of the connecting hole 18. Lubricating oil will flow into the connecting hole 18 through the through hole 31. The lubricating oil in the connecting hole 18 will be submerged in the sponge block 12. When the sponge block 12 has enough lubricating oil, the sponge block 12 drips oil to the oil pipe 8 fixed in the connecting hole 18. The oil pipe 8 will transport the lubricating oil to the rotating part of the spiral distributor body 5 to prevent the temperature from rising due to large friction when the spiral distributor body 5 rotates.

[0027] The inner wall of the sliding plate groove 29 is provided with a sliding plate 13. A push block 20 is fixed on the lower surface of the sliding plate 13. The sliding plate 13 corresponds to and is engaged with the second sliding groove 30, forming a movable connection. Since the length of the sliding plate 13 is less than the distance that the lifting rod 11 moves, when the lifting rod 11 moves, the fixed block 17 in the lifting rod groove 16 near the lifting arm 3 will block the sliding plate 13 through the push block 20, so that the sliding plate 13 moves in the sliding plate groove 29. The movement of the sliding plate 13 will expose the through hole 31. The annular groove 21 is provided with a receiving groove 24. The receiving groove 24 is provided with a slot 25 near the end. The bottom of the inner wall of the slot 25 is provided with a toothed block groove 26. The annular groove 21 is provided with a gear groove 27 in the middle. The gear groove 27 penetrates to the oil groove 28. The toothed block groove 26 is connected to the gear groove 27.

[0028] The inner wall of the storage slot 24 is provided with a baffle 35. A limiting block 32 is fixed on the upper surface of the baffle 35. The limiting block 32 corresponds to the limiting groove 19. A toothed block 33 is fixed on the bottom surface of the baffle 35. The toothed block 33 corresponds to the toothed block groove 26. A spring 34 is fixed on the inner wall of the storage slot 24 below the baffle 35.

[0029] A guide rod 37 is rotatably connected to the inner wall side surface of the gear groove 27. A stirring blade 23 is fixed to the outer surface of the guide rod 37. The stirring blade 23 is located on the outer surface of the guide rod 37 inside the oil groove 28. The rotation of the guide rod 37 will drive the stirring blade 23 to rotate. The stirring blade 23 stirs the lubricating oil in the oil groove 28, preventing the lubricating oil from accumulating in the oil groove 28 and facilitating the flow of the lubricating oil into the through hole 31. A transmission tooth groove 39 is opened on the outer surface of the end of the guide rod 37 near the annular groove 21. A gear 36 is rotatably connected to the outer surface of the transmission tooth groove 39.

[0030] The inner wall of gear 36 has an inner tooth groove 40. A rotating shaft 41 is fixed on the inner side surface of gear 36. A transmission gear 38 is rotatably connected to the outer surface of the rotating shaft 41. The transmission gear 38, the transmission tooth groove 39 and the inner tooth groove 40 correspond to each other. The tooth block 33 corresponds to the outer surface of gear 36. Since the diameter of the transmission gear 38 and the guide rod 37 is much smaller than the diameter of gear 36, the limiting block 32 will rotate gear 36 by 30 degrees through the tooth block 33. The rotation of gear 36 by 30 degrees will rotate the guide rod 37 one revolution through the transmission gear 38. At the same time, since more than one tooth block 32 moves, the stirring blade 23 can be used to stir the lubricating oil in the oil tank 28.

[0031] The present invention also discloses a construction process for a roadbed paving device for municipal road construction as described above, comprising the following steps: Step 1: Lifting. The lifting arm 3 is a special adjustment tool for adjusting the height of the vibrator 4 off the ground. When it is necessary to adjust the height of the spiral distributor body 5 off the ground, drive the lifting arm 3 so that the lifting hole 2 corresponds to the lifting rod 11. At this time, hold the handle collar 14 and pull it to lock the lifting rod 11 into the lifting hole 2. Then rotate the handle collar 14. Since the edges of the limiting groove 19 and the limiting block 32 are curved, rotating the handle collar 14 can squeeze the limiting block 32 and make it retract into the receiving groove 24. When the handle collar 14 is rotated to the point where it is no longer in contact with the connecting gap 10, then... The limiting groove 19 and the limiting block 32 correspond and are locked. Under the restriction of the limiting block 32 and without the use of a large external force to pull, the handle collar 14 will not rotate, so that the lifting rod 11 is locked and fixed in the lifting hole 2. Since the lifting hole 2 and the lifting rod 11 are movably connected, there is no restriction during lifting. At this time, the auger distributor body 5 can be separated from the paver body 1 by tools, and the lifting arm 3 can be used to drive the auger distributor body 5 to lift. This lifting method does not require an external power mechanism, which reduces the cost of adjusting the height of the auger distributor body 5. Step 2: Lubrication. When the grip collar 14 is pulled from the positioning groove 9 on the side away from the lifting arm 3 to another set of positioning grooves 9, the sliding plate 13 will move with the lifting rod 11. Since the length of the sliding plate 13 is less than the distance the lifting rod 11 moves, the fixing block 17 in the lifting rod groove 16 near the lifting arm 3 will block the sliding plate 13 through the pushing block 20 when the lifting rod 11 moves, causing the sliding plate 13 to move in the sliding plate groove 29. The movement of the sliding plate 13 will expose the through hole 31. When the lifting rod 11... When the lifting hole 2 is engaged, the through hole 31 is fully exposed. Since there is lubricating oil in the oil groove 28, when the through hole 31 is exposed, the lubricating oil will flow into the connecting hole 18 through the through hole 31. The lubricating oil in the connecting hole 18 will be submerged in the sponge block 12. When the sponge block 12 has enough lubricating oil, the sponge block 12 drips oil into the oil pipe 8 fixed in the connecting hole 18. The oil pipe 8 will transport the lubricating oil to the rotating part of the spiral distributor body 5 to prevent the temperature from rising due to large friction when the spiral distributor body 5 rotates. Step 3: Stirring. Rotating the handle collar 14 will squeeze the limiting block 32 into the receiving groove 24. The downward movement of the limiting block 32 will drive the toothed block 33 to move downward. Since the toothed block 33 corresponds to the tooth groove on the outer surface of the gear 36, the movement of the toothed block 33 will drive the gear 36 to rotate. The rotation of the gear 36 will drive the transmission gear 38 to rotate. The rotation of the transmission gear 38 will drive the guide rod 37 to rotate through the transmission tooth groove 39. The rotation of the guide rod 37 will drive the stirring blade 23 to rotate. Since the diameter of the transmission gear 38 and the guide rod 37 is much smaller than the diameter of the gear 36, the limiting block 32 will rotate the gear 36 by 30 degrees through the toothed block 33. The rotation of the gear 36 by 30 degrees will drive the guide rod 37 to rotate one revolution through the transmission gear 38. At the same time, since more than one toothed block 32 moves, it can satisfy the stirring blade 23 to stir the lubricating oil in the oil tank 28, prevent the lubricating oil from accumulating in the oil tank 28, and facilitate the flow of the lubricating oil into the through hole 31.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

A spring (34) is fixed on the inner wall of the storage groove (24) below the baffle (35).

6. A roadbed paving device for municipal road construction according to claim 5, characterized in that: A guide rod (37) is rotatably connected to the inner wall side surface of the gear groove (27), and a stirring blade (23) is fixed on the outer surface of the guide rod (37). The stirring blade (23) is located on the outer surface of the guide rod (37) inside the oil groove (28). A transmission tooth groove (39) is opened on the outer surface of the end of the guide rod (37) near the annular groove (21), and a gear (36) is rotatably connected to the outer surface of the transmission tooth groove (39).

7. A roadbed paving device for municipal road construction according to claim 6, characterized in that: The gear (36) has an inner tooth groove (40) on its inner wall. A rotating shaft (41) is fixed on the inner side surface of the gear (36). A transmission gear (38) is rotatably connected to the outer surface of the rotating shaft (41). The transmission gear (38), the transmission tooth groove (39), and the inner tooth groove (40) correspond to each other. The tooth block (33) corresponds to the outer surface of the gear (36).

8. A construction process for a roadbed paving device for municipal road construction according to claim 7, characterized in that: Includes the following steps: Step 1: Lifting. The lifting arm (3) is a special adjustment tool for adjusting the height of the vibrator (4) off the ground. When it is necessary to adjust the height of the spiral distributor body (5) off the ground, drive the lifting arm (3) so that the lifting hole (2) corresponds to the lifting rod (11). At this time, hold the handle collar (14) and pull it to lock the lifting rod (11) into the lifting hole (2). Then rotate the handle collar (14). Since the edges of the limiting groove (19) and the limiting block (32) are curved, rotating the handle collar (14) can squeeze the limiting block (32) and make it retract into the receiving groove (24). When the handle collar (14) rotates to the point where it is no longer in contact with the connecting gap (10), Next, the limiting groove (19) and the limiting block (32) are aligned and locked. Under the restriction of the limiting block (32) and without the use of a large external force to pull, the handle collar (14) will not rotate, so that the lifting rod (11) is locked and fixed in the lifting hole (2). Since the lifting hole (2) and the lifting rod (11) are connected, they will not be restricted when lifting. At this time, the auger distributor body (5) can be separated from the paver body (1) by tools, and the lifting arm (3) can be used to drive the auger distributor body (5) to lift. This lifting method does not require an external power mechanism, which reduces the cost of adjusting the height of the auger distributor body (5). Step 2: Lubrication. When the grip collar (14) is pulled from the positioning groove (9) away from the lifting arm (3) to another set of positioning grooves (9), the sliding plate (13) will move with the lifting rod (11). Since the length of the sliding plate (13) is less than the distance the lifting rod (11) moves, the fixing block (17) of the lifting arm (3) in the lifting rod groove (16) will block the sliding plate (13) through the pushing block (20) when the lifting rod (11) moves, so that the sliding plate (13) moves in the sliding plate groove (29). The movement of the sliding plate (13) will expose the through hole (31). When the lifting rod... (11) When it is engaged with the lifting hole (2), the through hole (31) is fully exposed. Since there is lubricating oil in the oil tank (28), when the through hole (31) is exposed, the lubricating oil will flow into the connecting hole (18) through the through hole (31). The lubricating oil in the connecting hole (18) will be submerged in the sponge block (12). When the sponge block (12) has enough lubricating oil, the sponge block (12) drips oil into the oil pipe (8) fixed in the connecting hole (18). The oil pipe (8) will transport the lubricating oil to the rotating part of the spiral distributor body (5) to prevent the spiral distributor body (5) from getting too hot due to friction when it rotates. Step 3: Stirring. Rotating the handle ring (14) will squeeze the limiting block (32) into the receiving groove (24). The downward movement of the limiting block (32) will drive the toothed block (33) to move downward. Since the toothed block (33) corresponds to the outer surface tooth groove of the gear (36), the movement of the toothed block (33) will drive the gear (36) to rotate. The rotation of the gear (36) will drive the transmission gear (38) to rotate. The rotation of the transmission gear (38) will drive the guide rod (37) to rotate through the transmission tooth groove (39). The rotation of the guide rod (37) will drive the stirring blade. (23) Rotation: Since the diameters of the transmission gear (38) and the guide rod (37) are much smaller than the diameter of the gear (36), the limiting block (32) will rotate the gear (36) by 30 degrees through the tooth block (33), and the rotating gear (36) will rotate the guide rod (37) one revolution through the transmission gear (38). At the same time, since more than one tooth block (33) moves, it can satisfy the stirring blade (23) to stir the lubricating oil in the oil tank (28), prevent the lubricating oil from accumulating in the oil tank (28), and facilitate the flow of lubricating oil into the through hole (31).
