Description
Technical Field
[0001] This invention relates to the field of municipal road engineering technology, and more specifically, to a non-stop municipal road construction process and equipment. Background Technology
[0002] In the construction and maintenance of municipal roads, small-scale road repairs are crucial. However, current municipal road construction techniques present numerous problems for small-scale repairs. Hollow areas and unevenness frequently occur within the laid asphalt concrete pavement, severely impacting road quality and service life. Road rollers are costly to operate, and their movement and maneuvering in confined spaces are inconvenient. Therefore, it is necessary to simultaneously level the asphalt concrete and eliminate hollow areas.
[0003] The causes of voids are complex. In the asphalt mixing stage, insufficient mixing often occurs due to inadequate equipment performance or improper operation, resulting in uneven distribution of asphalt and aggregates. During road paving, insufficient precision of construction equipment or improper operation methods can easily lead to voids within the pavement. For example, some traditional pavers struggle to precisely control paving thickness and uniformity in small-scale operations; compaction equipment may fail to effectively eliminate air within the pavement, leaving voids. To solve these problems, it's necessary to address both the raw material mixing stage and the paving process. For instance, increasing the mixing speed and duration of the mixing mechanism can reduce air bubbles in the asphalt concrete. Furthermore, the paving stage requires the use of vibration structures to eliminate voids and make the asphalt concrete more compact. However, it's difficult to simultaneously eliminate these voids during the paving process. Additionally, ensuring thorough mixing of the asphalt concrete and maintaining uninterrupted construction are crucial.
[0004] In view of this, we propose a non-stop municipal road construction process and equipment to improve the shortcomings of existing technologies. Summary of the Invention
[0005] An uninterrupted municipal road construction equipment is provided to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, one objective of the present invention is to provide an uninterrupted municipal road construction equipment, including a mixing assembly, a speed reduction and torque increase assembly coaxially connected to one end of the output shaft of the mixing assembly, a leveling assembly coaxially connected to the bottom of the speed reduction and torque increase assembly, and a pair of symmetrically arranged vibration assemblies provided inside the leveling assembly, the vibration assemblies including a plurality of driving members and a plurality of driven members. The mixing component is used to mix the raw materials for paving the road surface. During the mixing process, the deceleration and torque-increasing component rotates synchronously with the mixing component. The deceleration and torque-increasing component drives the leveling component to level the mixed paving materials. The deceleration and torque-increasing component also ensures the continuity of the two working processes: mixing and feeding by the mixing component and leveling by the leveling component. During the leveling process, several driven components are moved up and down by the driving component. The bottom of the leveling component is struck by the driven components, and the leveling component can also vibrate the paving materials.
[0007] As a further improvement to this technical solution, the stirring assembly includes a stirring vessel, a main rod is provided at the center of the stirring vessel, a motor is provided at one end of the main rod, the main rod and the output shaft of the motor are coaxially connected, the top and bottom of the stirring vessel are respectively provided with a feed port and a discharge port, the feed port is located at the end closer to the motor, and the discharge port is located at the end farther away from the motor, and a stirring mechanism is coaxially connected to the main rod.
[0008] As a further improvement to this technical solution, the stirring mechanism includes several augers, and the radius of the several augers gradually decreases from the end closer to the motor to the end farther away from the motor.
[0009] As a further improvement to this technical solution, the speed reduction and torque increase assembly includes a drive gear coaxially connected to the main rod, a driven gear meshing on one side of the drive gear, and a reciprocating lead screw coaxially connected to the bottom of the driven gear.
[0010] As a further improvement to this technical solution, the number of teeth of the driven gear is greater than the number of teeth of the driving gear.
[0011] As a further improvement to this technical solution, the leveling component includes an active wedge block that is threadedly connected to a reciprocating lead screw, and a pair of symmetrically arranged driven wedge seats are slidably connected to the bottom of the active wedge block.
[0012] As a further improvement to this technical solution, the active component includes several guide grooves opened at the bottom of the active wedge block, and several power grooves are spaced apart on the inner top wall of each of the several guide grooves. The top of each of the two driven wedge seats is provided with an installation cavity, and several driven components are located in the installation cavity. Each driven component includes a pair of limiting plates spaced apart from top to bottom. Several guide rods are slidably connected to the two limiting plates. A spring is sleeved around the periphery of the several guide rods between the two limiting plates, and a vibrating hammer is provided at the bottom of each of the several guide rods.
[0013] The second objective of this invention is to provide a process for operating the aforementioned uninterrupted municipal road construction equipment, comprising the following steps: S1. Put the raw materials required for paving the road into the mixing unit, turn on the power to mix the raw materials, and then pour the mixed paving materials onto the road surface. S2. During the mixing process of the mixing component, the mixing component drives the deceleration and torque-increasing component to rotate. After the deceleration and torque-increasing component reduces the driving force of the mixing component to rotate and increases the torque, the deceleration and torque-increasing component drives the leveling component to level the paving material poured onto the road surface. S3. While the leveling component is leveling the paving material, the driving component is driven by the deceleration and torque-increasing component to move up and down reciprocatingly. The driven component is also moved up and down reciprocatingly by the push of the driving component, continuously striking the bottom of the deceleration and torque-increasing component, thereby vibrating the paving material.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this uninterrupted municipal road construction equipment, a mixing component is used to mix the raw materials for paving the road surface. During the mixing process, a speed-reducing and torque-increasing component rotates synchronously with the mixing component. Specifically, as the motor drives the main rod to rotate, the auger rotates, mixing the raw materials added to the mixing tank and driving the raw materials from one end of the inlet to one end of the outlet, thus ensuring more thorough mixing of the asphalt concrete raw materials used for paving. The speed-reducing and torque-increasing component drives the leveling component to level the mixed paving materials. The speed-reducing and torque-increasing component also ensures the continuity of the two working processes: mixing and feeding by the mixing component and leveling by the leveling component. Specifically, the drive gear is subjected to... Driven by the main rod, the drive gear rotates, which in turn drives the driven gear to rotate. The driven gear then drives the reciprocating screw at the bottom to rotate. Since the number of teeth on the driven gear is greater than that on the drive gear, the rotational driving force of the main rod is transmitted to the reciprocating screw. Compared to the main rod being driven by the motor, the reciprocating screw rotates at a lower speed and with a higher torque. The reciprocating screw drives the threaded drive wedge to move up and down. Driven by the drive wedge, the two driven wedges move back and forth, thus leveling the asphalt concrete poured from the discharge port onto the road surface. The low speed and high torque of the reciprocating screw provide sufficient driving force for leveling the road surface, while ensuring that the speed at which the driven wedges level the road surface keeps up with the feeding speed of the mixing tank.
[0015] 2. In this uninterrupted municipal road construction equipment, during the process of leveling the paving material by the leveling component, several driven parts are moved up and down by the driving part. The bottom of the leveling component is struck by the driven parts. The leveling component can also vibrate the paving material. Specifically, the driving wedge is driven by the reciprocating screw to move up and down, the driven wedge seat moves left and right, the top of the guide rod is in the guide groove, when the top of the guide rod is in the power groove, the spring is in the natural state, when the top of the guide rod is in the guide groove, the spring is compressed, and at the same time the vibrating hammer strikes the bottom of the driven wedge seat. As the top of the guide rod continuously moves through each power groove, the guide rod continuously moves up and down under the action of the spring restoring force, driving the vibrating hammer to continuously strike the bottom of the driven wedge seat, thereby vibrating the asphalt concrete laid on the road surface.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please see Figures 1-8 As shown, the purpose of this embodiment is to provide an uninterrupted municipal road construction equipment, including a mixing component 10. One end of the output shaft of the mixing component 10 is coaxially connected to a speed reduction and torque increase component 20. The bottom of the speed reduction and torque increase component 20 is coaxially connected to a leveling component 30. The leveling component 30 is provided with a pair of symmetrically arranged vibration components 40. The vibration components 40 include a number of driving components and a number of driven components. The mixing component 10 is used to mix the raw materials for paving the road surface. During the mixing process, the deceleration and torque-increasing component 20 rotates synchronously with the mixing component 10. The deceleration and torque-increasing component 20 drives the leveling component 30 to level the mixed paving materials. The deceleration and torque-increasing component 20 can also ensure the continuity of the two working processes of mixing and feeding by the mixing component 10 and leveling by the leveling component 30. During the leveling process, several driven parts are moved up and down by the driving part. The bottom of the leveling component 30 is struck by the driven parts. The leveling component 30 can also vibrate the paving materials.
[0020] Working principle: First, the raw materials required for paving the road surface are put into the mixing component 10, and the power is turned on to mix the raw materials. Then, the mixed paving materials are poured onto the road surface. During the mixing process of the mixing component 10, the mixing component 10 drives the deceleration and torque-increasing component 20 to rotate. After the deceleration and torque-increasing component 20 reduces the driving force of the mixing component 10 and increases the torque, the deceleration and torque-increasing component 20 drives the leveling component 30 to level the paving materials poured onto the road surface. While the leveling component 30 is leveling the paving materials, the driving component is driven by the deceleration and torque-increasing component 20 to move up and down reciprocally, and the driven component is pushed by the driving component to also move up and down reciprocally, continuously tapping the bottom of the deceleration and torque-increasing component 20, thereby vibrating the paving materials.
[0021] First, the specific structure of the stirring assembly 10 is disclosed. The stirring assembly 10 includes a stirring vessel 11. A main rod 12 is provided in the center of the stirring vessel 11. A motor 13 is provided at one end of the main rod 12. The output shafts of the main rod 12 and the motor 13 are coaxially connected. The top and bottom of the stirring vessel 11 are respectively provided with a feed port and a discharge port. The feed port is located at the end closer to the motor 13, and the discharge port is located at the end farther away from the motor 13. A stirring mechanism is coaxially connected to the main rod 12. Furthermore, the mixing mechanism includes several augers 14, with the radius of the augers 14 gradually decreasing from the end closest to the motor 13 to the end furthest from the motor 13. As the motor 13 drives the main rod 12 to rotate, the augers 14 rotate, on the one hand stirring the raw materials added to the mixing vessel 11, and on the other hand driving the raw materials to move from the feed port to the discharge port, so that the asphalt concrete raw materials used for paving are mixed more thoroughly.
[0022] Secondly, the specific structure of the deceleration and torque-increasing assembly 20 is disclosed. The deceleration and torque-increasing assembly 20 includes a drive gear 21 coaxially connected to the main rod 12, a driven gear 22 meshing on one side of the drive gear 21, and a reciprocating lead screw 23 coaxially connected to the bottom of the driven gear 22. Furthermore, the number of teeth of the driven gear 22 is greater than the number of teeth of the driving gear 21; the driving gear 21 is driven to rotate by the main rod 12, and the driving gear 21 then drives the driven gear 22 to rotate, and the driven gear 22 then drives the reciprocating screw 23 at the bottom to rotate. Since the number of teeth of the driven gear 22 is greater than the number of teeth of the driving gear 21, after the rotational driving force of the main rod 12 is transmitted to the reciprocating screw 23, compared with the main rod 12 being driven by the motor 13, the reciprocating screw 23 rotates at a lower speed and with a greater torque, providing sufficient driving force for leveling the road surface.
[0023] Next, the specific structure of the leveling assembly 30 is disclosed. The leveling assembly 30 includes an active wedge 31 that is threadedly connected to the reciprocating lead screw 23. A pair of symmetrically arranged driven wedge seats 32 are slidably connected to the bottom of the active wedge 31. Furthermore, the reciprocating screw 23 drives the active wedge 31, which is threadedly connected to it, to move up and down in a reciprocating motion. Driven by the active wedge 31, the two driven wedge seats 32 move closer and further away from each other in a reciprocating motion, thereby spreading the asphalt concrete poured from the discharge port onto the road surface.
[0024] Finally, the specific structure of the vibration assembly 40 is disclosed. The active component includes several guide grooves 45 opened at the bottom of the active wedge block 31. Several power grooves 46 are spaced apart on the inner top wall of the several guide grooves 45. The top of the two driven wedge seats 32 are opened with mounting cavities. Several driven components are located in the mounting cavities. The driven components include a pair of limiting plates 41 spaced apart from top to bottom. Several guide rods 42 are slidably connected on the two limiting plates 41. Springs 43 are sleeved on the periphery of the several guide rods 42 between the two limiting plates 41. Vibration hammers 44 are provided at the bottom of the several guide rods 42. Furthermore, the active wedge 31 is driven by the reciprocating screw 23 to move up and down, while the driven wedge 32 moves left and right. When the top of the guide rod 42 is in the guide groove 45, the spring 43 is in its natural state when the top of the guide rod 42 is in the power groove 46, and the spring 43 is compressed when the top of the guide rod 42 is in the guide groove 45. At the same time, the vibrating hammer 44 strikes the bottom of the driven wedge 32. As the top of the guide rod 42 moves continuously through the power grooves 46, the guide rod 42 moves up and down continuously under the restoring force of the spring 43, driving the vibrating hammer 44 to strike the bottom of the driven wedge 32, thereby vibrating the asphalt concrete laid on the road surface, so that the driven wedge 32 can spread the asphalt concrete more compactly and evenly.
[0025] Example 2 This embodiment, based on the content provided in Embodiment 1, aims to provide a process for operating the uninterrupted municipal road construction equipment proposed in Embodiment 1. The specific steps are as follows: S1. The raw materials required for paving the road surface are put into the mixing tank 11 through the feed port. The power is turned on, and the motor 13 drives the main rod 12 to rotate. The main rod 12 then drives the auger 14 to rotate. The auger 14 mixes the asphalt concrete raw materials on the one hand, and drives the asphalt concrete from one end of the feed port to the other end of the discharge port on the other hand, so that the paving raw materials take more paths and time from the feed port to the discharge port, thereby making the raw materials more thoroughly mixed. Then the mixed paving raw materials are poured onto the road surface. S2. During the mixing of paving materials by the auger 14, the drive gear 21 is driven by the main rod 12 to rotate. The drive gear 21 then drives the driven gear 22 to rotate, and the driven gear 22 then drives the reciprocating screw 23 at the bottom to rotate. Since the number of teeth of the driven gear 22 is greater than the number of teeth of the drive gear 21, the rotational driving force of the main rod 12 is transmitted to the reciprocating screw 23. Compared with the main rod 12 being driven by the motor 13, the reciprocating screw 23 rotates at a lower speed and with a greater torque, providing sufficient driving force for leveling the road surface. The reciprocating screw 23 drives the drive wedge 31, which is threadedly connected to it, to move up and down reciprocally. Driven by the drive wedge 31, the two driven wedge seats 32 move closer and further away from each other, thereby leveling the asphalt concrete poured from the discharge port onto the road surface. S3. While the driven wedge seat 32 is spreading the paving material, the active wedge block 31 is driven by the reciprocating screw 23 to move up and down, and the driven wedge seat 32 moves left and right. When the top of the guide rod 42 is in the guide groove 45 and the top of the guide rod 42 is in the power groove 46, the spring 43 is in its natural state. When the top of the guide rod 42 is in the guide groove 45, the spring 43 will be compressed. At the same time, the vibrating hammer 44 will strike the bottom of the driven wedge seat 32. As the top of the guide rod 42 moves through each power groove 46, the guide rod 42 moves up and down under the action of the restoring force of the spring 43, which drives the vibrating hammer 44 to strike the bottom of the driven wedge seat 32, thereby vibrating the asphalt concrete laid on the road surface, so that the driven wedge seat 32 spreads the asphalt concrete more compactly and evenly.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
