Description

[0001] The utility model relates to the technical field of road expansion, in particular to a foundation processing device for road expansion. Background Art

[0002] When expanding a road, it is necessary to spread sand on the foundation and compact the sand using foundation treatment equipment to improve the stability of the road after the foundation expansion.

[0003] To this end, a Chinese patent document with announcement number CN220565207U discloses a road expansion foundation treatment equipment, including a frame, a transmission assembly is arranged at the upper end of the frame, the transmission assembly includes an articulated frame arranged on the frame, the middle part of the articulated frame is hinged to the frame, one end of the articulated frame is provided with a connecting shaft, an articulated plate is arranged at the end of the articulated frame away from the connecting shaft, a tamping assembly is arranged at the lower end of the articulated plate, a driving assembly is arranged on the side of the frame away from the articulated plate, the driving assembly includes a driving motor arranged on the frame, a soil turning assembly is arranged on the lower side of the frame, and an adjustable push rod is arranged on the side of the frame close to the articulated plate.

[0004] In the above technical solution, the main shaft is driven to rotate by a driving motor so that the toggle block can press down the connecting shaft to realize the rotation of the articulated frame, so that the tamping plate moves up, replacing the gear rack transmission. There is no need to worry about tooth playing, and the service life is long.

[0005] However, in the above technical solution, the driving motor and the tamping plate are not directly connected, but the vertical reciprocating movement of the tamping plate is achieved through a multi-stage transmission structure. Therefore, there is a large power attenuation. When tamping hard sand, it is difficult to compact the sand tightly, and the torque requirement for the motor is relatively high. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a foundation treatment device for road expansion, which can facilitate improving the compaction density of sand.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foundation treatment equipment for road expansion, including a vehicle body, a symmetrical connecting flange is provided on the vehicle body, a connecting shaft arranged in a horizontal direction is provided between the connecting flanges on both sides, the end of the connecting shaft is rotatably connected to the connecting flange, the connecting shaft is driven by a motor, a symmetrical driving rod is provided on the connecting shaft, one end of the driving rod is fixedly mounted on the connecting shaft, and the other end extends outward as a connecting end, a connecting frame is provided between the connecting ends on both sides, one end of the connecting frame is rotatably connected to the connecting end, and the other end extends downward as an extension end, a pressure plate is provided below the connecting frame, a connecting rod is integrally provided on the pressure plate, and the connecting rod and the extension end are connected by a universal joint.

[0009] The utility model is further configured as follows: a spring is sleeved on the outer periphery of the guide rod, one end of the spring is fixed to the guide plate, and the other end is fixed to the pressure plate.

[0010] The utility model is further configured as follows: a retaining frame is fixed in the guide hole, a peripheral wall of the guide hole is provided with an embedding groove, the embedding groove is multiple and evenly distributed along the circumference, balls are rollingly connected in the embedding groove, the peripheral wall of the retaining frame is provided with a clearance groove corresponding to the embedding groove, and the ball part extends outside the clearance groove and abuts against the guide rod.

[0011] The utility model is further configured as follows: a driving synchronous wheel is fixedly mounted on the connecting shaft, a driven shaft arranged in the horizontal direction is provided on the vehicle body, a driven synchronous wheel is fixedly mounted on the driven shaft, the driven synchronous wheel and the driving synchronous wheel are connected by a transmission belt, a tillage rod is fixedly mounted on the outer periphery of the driven shaft, and the tillage rod is multiple.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When compacting the sand, the connecting shaft is driven to rotate by the motor, so that the driving rod rotating with the connecting shaft can drive the connecting frame to move back and forth, thereby driving the pressure plate to move back and forth in the vertical direction to achieve compaction of the sand. In this solution, after the pressure plate is connected to the connecting frame through the connecting rod, it is directly connected to the connecting shaft through the driving rod, thereby simplifying the complexity of the transmission structure to reduce the power attenuation of the motor and reduce the requirements for the motor torque. Therefore, the technical problems in the prior art that the power attenuation of the motor is large and the torque requirements of the motor are high are effectively solved, thereby facilitating the improvement of the compaction density of the sand.

[0017] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] like Figures 1 to 3As shown, the utility model discloses a foundation treatment device for road expansion, including a vehicle body 1, a symmetrical connecting flange 101 is provided on the vehicle body 1, a connecting shaft 2 arranged in a horizontal direction is provided between the connecting flanges 101 on both sides, the end of the connecting shaft 2 is rotatably connected to the connecting flange 101, the connecting shaft 2 is driven by a motor 3, a symmetrical driving rod 4 is provided on the connecting shaft 2, one end of the driving rod 4 is sleeved and fixed to the connecting shaft 2, and the other end extends outward as a connecting end, a connecting frame 5 is provided between the connecting ends on both sides, one end of the connecting frame 5 is rotatably connected to the connecting end, and the other end extends downward as an extending end, a pressing plate 6 is provided below the connecting frame 5, and a pressing plate 6 is integrally provided The connecting rod 61 is connected to the extension end by a universal joint 7, and the universal joint 7 has a ball head. When the sand is compacted, the motor 3 drives the connecting shaft 2 to rotate, so that the driving rod 4 that rotates with the connecting shaft 2 can drive the connecting frame 5 to move back and forth, thereby driving the pressure plate 6 to move back and forth in the vertical direction to achieve the compaction of the sand. In this solution, after the pressure plate 6 is connected to the connecting frame 5 through the connecting rod 61, it is directly connected to the connecting shaft 2 through the driving rod 4, thereby simplifying the complexity of the transmission structure, reducing the power attenuation of the motor 3 and reducing the torque requirement of the motor 3, so as to facilitate improving the compaction density of the sand.

[0020] In this embodiment, the driving rod 4 can drive the connecting frame 5 to move back and forth as the connecting shaft 2 rotates. The principle is that a guide rod 8 extending upward is provided on the pressure plate 6, and the guide rods 8 are multiple and evenly arranged around the pressure plate 6. A guide plate 9 is provided above the pressure plate 6. The two ends of the guide plate 9 are respectively fixed to the connecting flanges 101 on both sides. Guide holes 91 corresponding to the guide rod 8 are provided around the guide plate 9. Therefore, after the motor 3 drives the connecting shaft 2 to rotate, the guiding cooperation formed by the guide hole 91 and the guide rod 8 can guide the moving path of the connecting frame 5, so that the connecting frame 5 can move in the vertical direction. Therefore, when the connecting end moves from the lower end to the higher end, the connecting frame 5 moves upward, and when the high end moves to the lower end, the connecting frame 5 moves downward.

[0021] In this embodiment, a spring 10 is further mounted on the outer periphery of the guide rod 8, one end of the spring 10 is fixed to the guide plate 9, and the other end is fixed to the pressure plate 6. Through the arrangement of the spring 10, the spring 10 can be squeezed during the upward movement of the pressure plate 6, so that during the downward movement of the pressure plate 6, the reaction force generated by the deformation of the spring 10 can act on the pressure plate 6, so that the pressure plate 6 can compact the sand more tightly and can drive the pressure plate 6 to press down faster.

[0022] In this embodiment, a retaining frame 11 is further fixed in the guide hole 91, and the peripheral wall of the guide hole 91 is provided with an embedding groove, and there are multiple embedding grooves that are evenly distributed around the circumference. A ball 12 is rollingly connected in the embedding groove, and the peripheral wall of the retaining frame 11 is provided with a clearance groove corresponding to the embedding groove. The ball 12 partially extends out of the clearance groove and abuts against the guide rod 8. The setting of the retaining frame 11 can prevent the ball 12 from escaping from the embedding groove. The ball 12 partially abuts against the guide rod 8, so that the guide rod 8 can drive the ball 12 to roll during the reciprocating movement, so that the rolling friction generated between the ball 12 and the guide rod 8 can reduce the friction force on the guide rod 8 during the movement, compared with the sliding friction generated by the direct contact between the guide rod 8 and the guide hole 91, thereby facilitating the motor 3 to drive the pressure plate 6 to reciprocate in the vertical direction, and further reducing the torque requirement for the motor 3.

[0023] In this embodiment, a driving synchronous wheel 13 is further fixedly mounted on the connecting shaft 2, and a driven shaft 14 is arranged in the horizontal direction on the vehicle body 1. A driven synchronous wheel 15 is fixedly mounted on the driven shaft 14. The driven synchronous wheel 15 and the driving synchronous wheel 13 are connected by a transmission belt 16. A soil-turning rod 17 is fixed to the outer periphery of the driven shaft 14. There are multiple soil-turning rods 17. After the motor 3 drives the connecting shaft 2 to rotate, the driving synchronous wheel 13 can rotate with the connecting shaft 2, thereby driving the driven shaft 14 to rotate through the transmission belt 16, so that the soil-turning rod 17 can rotate to loosen the sand, thereby facilitating the pressing plate 6 to compact the sand tightly.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
