Description

Technical Field

[0001] The present invention relates to the technical field of highway construction, and particularly to an auxiliary device for subgrade filling in highway construction. Background Art

[0002] During the process of highway construction, filling the subgrade is a crucial step to ensure its firmness and durability. Different types of fillers are usually used in this process to reinforce the subgrade, prevent settlement caused by vehicle weight and high-intensity vibration, and protect the subgrade from water damage through good drainage performance. In traditional technologies, when using fillers, appropriate materials are selected according to geological conditions. For example, soil is used for sections with better geological conditions, while sand and gravel are used for areas with poorer geological conditions or greater vibration. During construction, equipment is used to vibrate and compact the fillers to reduce voids and ensure the stability of the fillers.

[0003] However, a series of problems have emerged in the existing technologies during this process. Firstly, different compaction tools are required for different types of fillers (fine and coarse particles), which not only increases costs but also raises the complexity of construction management. Secondly, current vibration compaction equipment mainly relies on the design of eccentric wheels or eccentric shafts. Its basic working principle is that an electric motor drives a shaft with an eccentric weight to rotate, and this eccentric shaft impacts the oscillation head during rotation, causing the oscillation head to vibrate. Although this structure can generate a large vibration amplitude and is suitable for compacting coarse particle fillers, for relatively fine fillers, due to limited vibration frequency, it cannot effectively compress the internal voids of the fillers, affecting the final construction quality. Summary of the Invention

[0004] To solve the technical problem that the existing device has a single vibration mode and cannot efficiently handle multiple types of fillers, the present invention provides an auxiliary device for subgrade filling in highway construction.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] Auxiliary equipment for subgrade filling in highway construction, including a housing, a rotating shaft and a vibrating head. At least part of the vibrating head is located inside the housing, and the remaining part of the vibrating head extends out through the bottom of the housing. A motor is arranged inside the housing. The rotating shaft is arranged vertically, and the output end of the motor is connected to the rotating shaft. The rotating shaft is used to drive the vibrating head to vibrate. A rotating seat and a vibration generating member are arranged inside the housing. The rotating seat is connected to the rotating shaft, and a first magnet is arranged on the circumferential side of the rotating seat. The vibration generating member includes a fixing plate, a guide post and a return spring. A second magnet is fixed on the fixing plate. The guide post is arranged horizontally. One end of the guide post is fixed to the inner wall of the housing, and the other end of the guide post has a limiting block. The fixing plate is sleeved on the guide post, and the return spring is sleeved on the guide post. One end of the return spring is connected or in contact with the fixing plate, and the other end is connected or in contact with the inner wall of the housing. The second magnet is connected with a transmission member for hitting the vibrating head. The magnetic pole of the first magnet far from the central axis of the rotating shaft is the same as the magnetic pole of the second magnet close to the rotating seat. When the same magnetic poles of the first magnet and the second magnet approach each other, the second magnet can be driven away from the rotating seat. When the same magnetic poles of the first magnet and the second magnet move away from each other, the return spring can drive the second magnet to approach the rotating seat. It also includes an adjusting cylinder, a linkage rod and a hitting head. The adjusting cylinder is sleeved on the rotating shaft, and the adjusting cylinder is in threaded cooperation with the rotating shaft. An opening is formed on the housing for rotating the adjusting cylinder. One end of the linkage rod is hinged to the circumferential side of the adjusting cylinder, and the other end is hinged to the hitting head. The hitting head has a first state and a second state. The first state is that the hitting head does not contact the fixing plate during rotation, and the second state is that the hitting head contacts the fixing plate during rotation. By rotating the adjusting cylinder, the hitting head can be switched between the first state and the second state.

[0007] Further, a groove is formed on the side of the vibrating head. The transmission member includes a connecting rod and a rotating rod. The first end of the connecting rod is connected to the second magnet, and a transmission part is arranged at the second end of the connecting rod. The transmission part has a through hole. The first end of the rotating rod is hinged to the side wall of the groove, and the second end of the rotating rod passes through the through hole. First protrusions and second protrusions are arranged at intervals along the length direction of the rotating rod. The transmission part is located between the first protrusion and the second protrusion. First impact plates and second impact plates are arranged at the first end of the rotating rod. The first impact plates and the second impact plates form a V-shaped structure. When the transmission part contacts the first protrusion, the transmission part drives the rotating rod to rotate reversely, and the first impact plate hits the bottom wall of the groove. When the transmission part contacts the second protrusion, the transmission part drives the rotating rod to rotate forward, and the second impact plate hits the bottom wall of the groove.

[0008] Further, the first magnet is a bar magnet.

[0009] Further, the number of vibrating heads is two, and vibration generating members are arranged on both opposite sides of the rotating seat.

[0010] Further, the number of guide posts is two. The fixing plate has an opposite first side and a second side. One of the guide posts is located on the first side of the fixing plate, and the other guide post is located on the second side of the fixing plate.

[0011] Furthermore, two impact heads are arranged on the circumferential side of the adjusting cylinder. One of the impact heads is hinged to the left side of the adjusting cylinder through a linkage rod, and the other impact head is hinged to the right side of the adjusting cylinder through a linkage rod.

[0012] Furthermore, the fixing plate is a corrugated plate.

[0013] Furthermore, the fixing plate is made by stamping process.

[0014] Furthermore, the motor is equipped with a controller for adjusting the rotational speed of the motor output end.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present invention has two working modes. For some relatively delicate fillers, the magnetic force between the first magnet and the second magnet can be used for control. The rotating seat rotates together with the first magnet, and one end of the first magnet can repel the second magnet, thereby driving the oscillation generating member to work. This mode has a smaller force and can ensure that some relatively delicate fillers are tamped, avoiding large internal spaces and ensuring the quality of the constructed road. For sections with larger filler particles, by rotating the adjusting cylinder, the impact head is adjusted to move along the axial direction of the rotating shaft. When the rotating seat rotates, the impact head impacts the fixing plate, generating a greater impact force and making the vibration amplitude of the oscillation head larger, thereby vibrating the fillers with larger particles to ensure that the fillers with larger particles are tamped. Such a design enables a single device to handle fillers with different particle sizes, with stronger adaptability and reduced costs for enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Referring to Figures 1 to 4 , the present invention provides an auxiliary device for subgrade filling in highway construction.

[0027] As Figures 1 to 4As shown, in an embodiment of the present solution, an auxiliary device for subgrade filling in highway construction includes a housing 1, a rotating shaft 2, and a vibrating head 3. At least a part of the vibrating head 3 is located inside the housing 1, and the remaining part of the vibrating head 3 extends out through the bottom of the housing 1. A motor is arranged inside the housing 1. The rotating shaft 2 is vertically arranged, and the output end of the motor is connected to the rotating shaft 2. The rotating shaft 2 is used to drive the vibrating head 3 to vibrate. A rotating seat 4 and a vibration generating member are arranged inside the housing 1. The rotating seat 4 is connected to the rotating shaft 2. A first magnet 5 is arranged on the circumferential side of the rotating seat 4. The vibration generating member includes a fixing plate 6, a guide post 7, and a return spring 8. A second magnet 9 is fixed on the fixing plate 6. The guide post 7 is horizontally arranged. One end of the guide post 7 is fixed to the inner wall of the housing 1, and the other end of the guide post 7 has a limit block 10. The fixing plate 6 is sleeved on the guide post 7. The return spring 8 is sleeved on the guide post 7. One end of the return spring 8 is connected to or in contact with the fixing plate 6, and the other end is connected to or in contact with the inner wall of the housing 1. The second magnet 9 is connected to a transmission member 11 for hitting the vibrating head 3. The magnetic pole of the first magnet 5 away from the central axis of the rotating shaft 2 is the same as the magnetic pole of the second magnet 9 close to the rotating seat 4. When the same magnetic poles of the first magnet 5 and the second magnet 9 approach each other, the second magnet 9 can be driven away from the rotating seat 4. When the same magnetic poles of the first magnet 5 and the second magnet 9 move away from each other, the return spring 8 can drive the second magnet 9 to approach the rotating seat 4. It also includes an adjusting cylinder 12, a linkage rod 13, and an impact head 14. The adjusting cylinder 12 is sleeved on the rotating shaft 2, and the adjusting cylinder 12 is in threaded cooperation with the rotating shaft 2. An opening 15 is provided on the housing 1 for an operator to reach into the opening 15 to rotate and adjust the adjusting cylinder 12. One end of the linkage rod 13 is hinged to the circumferential side of the adjusting cylinder 12, and the other end is hinged to the impact head 14. The impact head 14 has a first state and a second state. The first state is that the impact head 14 does not contact the fixing plate 6 during rotation, and the second state is that the impact head 14 contacts the fixing plate 6 during rotation. By rotating the adjusting cylinder 12, the impact head 14 can be switched between the first state and the second state.

[0028] As Figure 4 shown, since the adjusting cylinder 12 is in threaded cooperation with the rotating shaft 2, to ensure that the adjusting cylinder 12 will not generate displacement in the axial direction of the rotating shaft 2 due to the rotation of the rotating shaft 2. The design of the thread needs to consider appropriate tolerances. The threaded cooperation between the adjusting cylinder 12 and the rotating shaft 2 should have sufficient friction and accuracy to ensure that the position can be smoothly adjusted when the adjusting cylinder 12 is rotated and remains fixed without external force. A locking device, such as a fastening screw, can also be installed on the adjusting cylinder 12. A threaded hole is provided on the adjusting cylinder 12, and the fastening screw is in threaded cooperation with the threaded hole. After the adjusting cylinder 12 is adjusted to the required position, the rotating shaft 2 can be pressed by rotating the fastening screw, thereby preventing the adjusting cylinder 12 from generating unnecessary movement due to the rotation of the rotating shaft 2.

[0029] For a motor (not shown), a controller for adjusting the rotational speed of the output end of the motor can be provided for the motor, so that the oscillation frequency of the oscillation head 3 can be adjusted.

[0030] One oscillation head 3 can be provided and an oscillation generating member can be provided. When the rotating seat 4 rotates driven by the rotating shaft 2 and the same magnetic poles of the first magnet 5 and the second magnet 9 approach each other, the second magnet 9 moves away from the rotating seat 4 under the action of magnetic force, and then drives the transmission member 11 to impact the oscillation head 3. When the same magnetic poles of the first magnet 5 and the second magnet 9 move away from each other, under the action of the return spring 8, the second magnet 9 approaches the rotating seat 4 under the action of elastic force. When the rotating shaft 2 rotates one week, the transmission member 11 impacts the oscillation head 3 once, forming a periodic motion. Increasing the rotational speed of the rotating shaft 2 can increase the frequency of the transmission member 11 impacting the oscillation head 3, that is, increase the oscillation frequency of the oscillation head 3.

[0031] As Figure 2 shown, the oscillation head 3 can also be provided as two or more. Here, taking two as an example, oscillation generating members are provided on both opposite sides of the rotating seat 4. One first magnet 5 can be provided or the first magnet 5 can be provided as a bar magnet, or two first magnets 5 can be provided. If two first magnets 5 are provided, when the rotating shaft 2 rotates one week, both of the two first magnets 5 will drive the second magnet 9 to move away from the rotating seat 4, that is, when the rotating shaft 2 rotates one week, the transmission member 11 will impact the oscillation head 3 twice; if one first magnet 5 is provided or the first magnet 5 is provided as a bar magnet, when the rotating shaft 2 rotates one week, the transmission member 11 will impact the oscillation head 3 once.

[0032] The present invention has two working modes. When compacting fine fillers, the adjusting cylinder 12 and the impact head 14 are not introduced. At this time, only relying on the magnetic force, the transmission member 11 is driven to impact the oscillation head 3. This mode has a smaller force and is suitable for compacting fine fillers; when compacting coarse particle fillers, by rotating the adjusting cylinder 12, the adjusting cylinder 12 moves vertically. At this time, the adjusting cylinder 12 and the impact head 14 are introduced. The impact head 14 will impact the fixing plate 6 during rotation, and then the transmission member 11 generates a displacement, and the transmission member 11 impacts the oscillation head 3. This mode has a large impact force and is suitable for compacting coarse particle fillers.

[0033] As Figure 3As shown, for the setting of the transmission member 11, only one impact rod or impact block can be used to impact the shock head 3; the transmission member 11 can also be set as follows. The transmission member 11 includes a connecting rod 111 and a rotating rod 112. A groove 16 is formed on the side of the shock head 3. The first end of the connecting rod 111 is connected to the second magnet 9. A transmission part 17 is provided at the second end of the connecting rod 111. The transmission part 17 has a through hole 18. The first end of the rotating rod 112 is hinged to the side wall of the groove 16. The second end of the rotating rod 112 passes through the through hole 18. The first protrusion 19 and the second protrusion 20 are arranged at intervals along the length direction of the rotating rod 112. The transmission part 17 is located between the first protrusion 19 and the second protrusion 20. The first impact plate 21 and the second impact plate 22 are arranged at the first end of the rotating rod 112. The first impact plate 21 and the second impact plate 22 form a V-shaped structure. When the transmission part 17 contacts the first protrusion 19, the transmission part 17 drives the rotating rod 112 to rotate reversely, and the first impact plate 21 impacts the bottom wall of the groove 16. When the transmission part 17 contacts the second protrusion 20, the transmission part 17 drives the rotating rod 112 to rotate forward, and the second impact plate 22 impacts the bottom wall of the groove 16.

[0034] For the setting of the guide post 7, one or more guide posts 7 can be set. Preferably, the number of the guide posts 7 is two. The fixing plate 6 has an opposite first side and second side. One of the guide posts 7 is located on the first side of the fixing plate 6, and the other guide post 7 is located on the second side of the fixing plate 6.

[0035] For the setting of the impact head 14, one or more impact heads 14 are set. Preferably, two impact heads 14 are arranged on the circumferential side of the adjusting cylinder 12. One of the impact heads 14 is hinged to the left side of the adjusting cylinder 12 through a linkage rod 13, and the other impact head 14 is hinged to the right side of the adjusting cylinder 12 through a linkage rod 13.

[0036] Furthermore, the fixing plate 6 is a corrugated plate, which is made by stamping process. Since the fixing plate 6 is impacted for a long time, the corrugated plate is selected, presenting a corrugated bend, which enhances the structural rigidity and strength and ensures that the fixing plate 6 has sufficient strength when being impacted.
