Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention

[0036] See Figures 1-7As shown in the figure, the present invention provides a compaction device for the foundation pavement of road construction, including a central support platform 1 and a digital display control panel 12. Among them, the central support platform 1 serves as the basic support component of the entire device, bearing and connecting other key structures. It provides an installation foundation for the rolling wheel structure 2, the mobile support structure 3, the positioning support rod structure 5, etc. At the same time, it is hinged to the cross beam 4 through the support shaft 101, providing a fulcrum for the rotation of the cross beam 4. The lengths of both sides of the cross beam 4 centered on the central support platform 1 are the same. The two ends of the cross beam 4 are hinged with ramming blocks 8. In practical applications, the cross beam 4 serves as a force transmission and distribution component. On the one hand, it connects the ramming blocks 8 to transmit the ramming force; on the other hand, it cooperates with the weight pressing block structure 6 and the pulling and moving assembly 7. By changing the position of the weight pressing block and using the lever principle, the lifting and falling actions of both ends of the cross beam are realized. Each ramming block 8 is provided with a vibrator 10 capable of vibrating and compacting the road surface; the ramming block 8 is hinged to both ends of the cross beam 4 and rises and falls with the movement of the cross beam. The vibrator 10 thereon starts during the falling process of the ramming block, and applies high-frequency vibration force to the road surface through the vibrating rod 1001 to realize the vibration compaction of the road foundation pavement and improve the road surface density. A rolling wheel structure 2 is arranged on the central support platform 1, and two mobile support structures 3 symmetrically distributed centered on it are arranged on both sides of the rolling wheel structure 2. Two positioning support rod structures 5 for positioning and supporting the cross beam 4 are arranged on the central support platform 1; a weight pressing block structure 6 is arranged on the cross beam 4 to move along its length direction, and pulling and moving assemblies 7 for driving the movement of the weight pressing block structure 6 are respectively arranged at both ends of the cross beam 4.

[0037] See the attached drawings of the specification Figure 1 and Figure 6As shown in the figure, the rolling wheel structure 2 includes a wheel body 201, which is rotatably arranged in a C-shaped groove formed on the lower side of the central support platform 1. Wheel brackets 102 are fixedly arranged on both sides of the central support platform 1. Among them, it plays a role in supporting the wheel body 201, ensuring the stability and reliability of the wheel body 201 during rotation, and at the same time providing a structural basis for the installation and connection of the wheel body 201. The outer contour of the wheel bracket 102 is L-shaped. The upper end of the wheel bracket 102 is fixedly connected to the central support platform 1. An inner installation chamber 202 is formed inside the wheel body 201. A first motor 203 is fixedly arranged in the inner installation chamber 202. The output shaft end of the first motor 203 passes through one end of the wheel body 201 and is fixedly connected to one of the wheel brackets 102. The other end of the wheel body 201 is rotatably connected to the wheel bracket 102 through a rotating shaft. Ventilation and heat dissipation holes 204 for communicating the inner installation chamber 202 with the outside to dissipate heat from the first motor 203 are formed through both end faces of the wheel body 201, forming an air circulation channel to take away the heat generated when the first motor 203 works, preventing the motor from deteriorating or being damaged due to overheating, ensuring the normal operation of the motor. The output end of the digital display control panel 12 is electrically connected to the input end of the first motor 203. The entire rolling wheel structure 2 can rotate in the C-shaped groove on the lower side of the central support platform 1 through the wheel body 201, which can play a role in rolling and compacting the road surface, and also realizes the moving function of the equipment on the road surface during the ramming operation.

[0038] See the attached drawings in the specification Figure 2 and Figure 3 As shown in the figure, the mobile support structure 3 includes a wheel support block 301. Moving wheels 302 are rotatably arranged on both sides of the wheel support block 301. The wheel axis direction of the moving wheels 302 is parallel to the wheel axis direction of the wheel body 201, ensuring the consistency of the moving direction. During the operation of the equipment, it can share the weight of the equipment together with the rolling wheel structure 2 and play a supporting role to ensure the stability of the equipment on the road surface. A first hydraulic cylinder 303 for driving the wheel support block 301 to move relative to the central support platform 1 is arranged on the rolling wheel structure 2. The push rod head end of the first hydraulic cylinder 303 is fixedly connected to the wheel support block 301. Two first guide rods 304 symmetrically distributed with the first hydraulic cylinder 303 as the center are arranged on both sides of the first hydraulic cylinder 303, playing a guiding role to ensure the smooth and linear movement of the wheel support block 301 driven by the first hydraulic cylinder 303, avoiding situations such as deviation and shaking, and improving the accuracy and stability of the movement. One end of the two first guide rods 304 is fixedly connected to the wheel support block 301, and the other end of the two first guide rods 304 is slidably connected to a first guide slide hole formed at the corresponding position of the central support platform 1. The output end of the digital display control panel 12 is electrically connected to the input end of the first hydraulic cylinder 303. Through the above specific structural design, the contact state and support position of the moving wheels 302 with the ground can be adjusted according to the operation requirements, such as playing a role when the equipment needs to change the support posture, adapt to different road surface conditions or perform precise positioning.

[0039] See the attached instruction manual Figure 2 , Figure 4 and Figure 6 As shown, the weight block structure 6 includes a weight base block 601. Two parallel distribution insertion rods 603 are fixedly arranged on the upper side of the weight base block 601. A number of weight plates 602 are detachably arranged on the insertion rods 603. Through the above specific structural design, the weight base block 601 provides fixed support for the insertion rods 603 and moves along the cross beam 4 under the action of the pulling and moving assembly 7. By changing its own position, the moment at both ends of the cross beam 4 is adjusted to cooperate with the tamping operation of the tamping block 8. A jack for passing through the insertion rod 603 is formed through the weight plate 602. A limit sleeve 604 for upward movement limit of the weight base block 601 is sleeved on the top of the insertion rod 603. The limit sleeve 604 is sleeved on the top of the insertion rod 603 to limit the upward movement range of the weight plate 602 on the insertion rod, preventing the weight plate from detaching from the insertion rod 603 due to vibration, inclination, etc. during the operation of the equipment, and ensuring the integrity and stability of the weight block structure 6. Among them, the insertion rod 603 is vertically fixed on the upper side of the weight base block 601. On the one hand, it provides an installation and positioning structure for the weight plate 602 to stack them in an orderly manner; on the other hand, it acts together with the weight plate 602 to realize flexible adjustment of the overall weight of the weight block structure 6. By increasing or decreasing the number of weight plates 602, the requirements for the pressure magnitude in different road surface tamping operations can be met. As a component for increasing the weight, the weight plate 602 realizes convenient adjustment of the weight with a standardized and modular design, improving the adaptability of the equipment under different working conditions.

[0040] The pulling and moving assembly 7 includes two second guide rods 706 distributed in parallel. Both ends of the second guide rods 706 are fixedly arranged at both ends of the cross beam 4 through fixed seats, providing guidance for the movement of the weight pressing base block 601, ensuring that the weight pressing base block moves smoothly and linearly on the cross beam 4, avoiding deviation and shaking, and improving the moving accuracy. Both of its ends are fixed to both ends of the cross beam through fixed seats, determining the path direction of the movement of the weight pressing base block. The weight pressing base block 601 is provided with second guide sliding holes for sliding through the second guide rods 706. Bushings 605 are respectively arranged at both port ends of the second guide sliding holes. The bushings 605 are made of rubber material. An electric hoist 701 for pulling and moving the weight pressing base block 601 is arranged on each fixed seat. A towing rope 705 is arranged on the electric hoist 701. A second motor 702 for realizing the retraction and release of the towing rope 705 is arranged on the electric hoist 701, used for pulling and moving the weight pressing base block 601. Driven by the second motor 702, the retraction and release operation of the towing rope 705 is realized, thereby driving the weight pressing base block to move on the cross beam. The weight pressing base block 601 is provided with a wheel groove 707, and a movable pulley 708 is rotatably arranged in the wheel groove 707. In practical applications, the movable pulley 708 is installed in the wheel groove, changing the direction of the towing rope through the annular groove 709 on its outer side, achieving a labor-saving effect, and at the same time ensuring the smooth movement of the towing rope during the process of pulling the weight pressing base block, reducing friction and wear. An annular groove 709 for passing through the towing rope 705 is arranged along the circumferential direction on the outer side of the movable pulley 708. One end of the towing rope 705 changes direction and passes through the annular groove 709 and is fixedly connected to the fixed seat on its same side. One end of a connecting column 704 is fixedly connected to the electric hoist 701, and the other end of the connecting column 704 is connected to a connecting hole opened at the corresponding position of the fixed seat.

By changing the position of the weight pressing base block 601, the moment at both ends of the cross beam 4 is adjusted using the lever principle, thereby controlling the cross beam 4 to rotate with the central support platform 1 as the fulcrum, driving the tamper block 8 to rise and fall, and realizing the tamping operation on the road surface; at the same time, by adjusting the moving speed of the weight pressing base block 601, etc., the falling tamping force of the tamper block 8 can be controlled to meet the tamping requirements of different road surfaces.

[0041] The ramming block 8 is provided with a lifting groove 801 for realizing the up and down movement of the vibrator 10, providing a space channel for the up and down movement of the vibrator 10, enabling the vibrator 10 to move along a specific track within the ramming block 8, so as to perform vibrating compaction operations on the road surface at an appropriate time. The lower side of the ramming block 8 is penetrated and provided with more than two vibration impact perforations 804, which are channels for the vibrating rod 1001 to extend out and act on the road surface, enabling the vibration force generated by the vibrator to be effectively transmitted to the road surface and enhancing the compaction effect. The vibrator 10 is provided with a vibrating rod 1001 for being embedded in the vibration impact perforation 804, applying a vibration force to the road surface through high-frequency vibration, causing the road surface particles to be rearranged and compacted, and improving the compactness and flatness of the road surface. Both sides of the ramming block 8 are provided with a lifting drive structure 11 for driving the vibrator 10 to lift up and down within the lifting groove 801. See the attached Figure 2 and Figure 5 As shown in the figure, the lifting drive structure 11 includes side sliding grooves 802 opened on both sides of the ramming block 8. A support ear 1103 is slidably arranged up and down within the side sliding groove 802. One end of the support ear 1103 is fixedly connected to the vibrator 10.

The head end of the push rod 1102 of the electric telescopic rod 1101 slides downward through the support ear 1103 and is fixedly connected with a stop block 1106 by a bolt. A push sleeve 1104 is fixedly arranged on the outer side of the push rod 1102 above the support ear 1103. A spring 1105 is nested on the outer side of the push rod 1102 between the support ear 1103 and the stop block 1106.

The positioning support rod structure 5 realizes reliable positioning and support for the cross beam 4, maintains the stability of the equipment when the whole equipment moves or does not perform ramming operations, avoids accidental rotation of the cross beam, and ensures the safety and stability of the equipment operation.

[0044] The working principle and technical effects of the present invention:

[0045] During use, the first motor 203 is controlled by the digital display control panel 12 to drive the rotation of the wheel body 201 of the rolling wheel structure 2, realizing the movement of the equipment on the road surface. The first motor 203 inside the wheel body 201 dissipates heat through the ventilation and heat dissipation holes 204. The digital display control panel 12 controls the first hydraulic cylinder 303 to push the wheel support block 301 and the moving wheel 302 of the moving support structure 3, thereby adjusting the height position of the moving wheel 302. During tamping operation, the bottom side height of the moving wheel 302 is adjusted to be higher than the bottom side height of the wheel body 201. When not performing tamping operation, in order to facilitate the overall movement, the bottom side height of the moving wheel 302 is adjusted to be lower than the bottom side height of the wheel body 201.

[0046] The weight block structure 6 adjusts the overall weight by adding or reducing the weight plates 602 on the insertion rods 603 and fixing them with the limit sleeves 604 and set bolts, so as to cooperate with the pulling and moving assembly 7 to adjust the pulling speed of the weight block structure 6, thereby adjusting the articulated rotation speed of the cross beam 4 relative to the central support platform 1 and the falling tamping force of the tamping block 8.

[0047] The electric hoist 701 of the pulling and moving assembly 7, under the action of the second motor 702, moves the weight base block 601 along the second guide rod 706 on the cross beam 4 through components such as the traction rope 705 and the movable pulley 708. When the weight block structure 6 moves to both ends of the cross beam 4, based on the lever principle, the cross beam 4 is hinged and rotated relative to the central support platform 1 with the support shaft 101 as the fulcrum, thereby realizing the tamping of the road surface by the tamping blocks 8 at both ends in sequence.

[0048] The lifting of the cross beam 4 drives the tamping blocks 8 hinged to its two ends to fall. The electric telescopic rod 1101 of the lifting drive structure 11 drives the ear 1103 and the vibrator 10 to move downward in the side chute 802 and the lifting chute 801. The vibrating rod 1001 of the vibrator 10 exerts a vibrating force on the road surface through the vibration punching hole 804, realizing the tamping and compaction of the road surface. The spring 1105 assists in buffering and resetting.

[0049] The second hydraulic cylinder 501 of the positioning support rod structure 5 is hinged to the central support platform 1 through the hinge seat 504. The push rod pushes the positioning block 503 to be clamped with the positioning insertion hole 401 on the lower side of the cross beam 4, positioning and supporting the cross beam 4, avoiding unstable situations during overall movement and when not performing tamping operations, especially fixing the position of the cross beam 4.
