Description

Technical Field

[0001] The utility model relates to the technical field related to road construction engineering, in particular to a greenway road paving device for stabilizing soil pavement. Background Art

[0002] Currently, the primary paving material used for suburban greenways in China is a combination of regular asphalt and colored asphalt. Asphalt causes irreversible pollution to soil, water, and the atmosphere, and is detrimental to preserving and minimizing disturbance to the native environment. Therefore, it is unsuitable for greenways in heritage sites or ecologically sensitive areas. In response to this, the most local material available was sought: the existing soil. However, as a pavement material, this soil is unstable and prone to cementation, making it unsuitable for use as a public greenway. Therefore, a new type of stabilized soil pavement was proposed. The key technical support for stabilizing soil pavements was derived from the curing agents used for desilting rivers and lakes. This curing agent, made from industrial waste, was mixed with the soft, native soil on site. The road was then paved using a road paving device, creating a stabilized soil pavement that blends seamlessly with the existing environment.

[0003] Existing road paving equipment usually adopts a combination of a paver and a roller. After the pavement paving material is laid on the road to be paved, the roller rolls the road. However, the conditions of different road surfaces are different during road paving, resulting in the inability to guarantee the rolling force of the roller on the ground when the thickness of the road paving needs to be adjusted. Once the road paving thickness is low, the rolling force of the roller on the road surface is insufficient, which will cause the structural strength of the roadbed and road surface to be reduced.

[0030] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0031] See also Figures 1 to 8 In an embodiment of the present invention, a greenway road paving device for stabilizing a soil pavement includes a frame 1, a material box 2, a conducting structure, a rolling assembly and a threaded pushing member.

[0032] For details, please refer to Figure 1 、 Figure 6 and Figure 7 ,include;

[0033] A frame 1 and a material box 2 fixedly mounted on the frame 1, wherein the discharge end at the bottom of the material box 2 passes through the frame 1 and is provided with a conducting structure;

[0034] It also includes a rolling assembly rotatably mounted on the bottom of the frame 1;

[0035] Symmetrically arranged threaded pushers are installed on the frame 1 and connected to the rolling assembly, and one group of threaded pushers is connected to the conductive structure. When the conductive structure is controlled to change the conductive area, the height of the rolling assembly and the ground can be adjusted.

[0036] In detail, in this embodiment, the greenway road paving device for stabilized soil pavement described in the utility model is adopted. When in use, when the frame 1 travels to the designated paving area, the threaded pusher is started to work to adjust the height between the rolling assembly and the paved ground. At the same time, the threaded pusher controls the conductive structure to release the closed state of the discharge end of the discharge box 2, so that while the conductive area of ​​the discharge end of the discharge box 2 changes, the height of the rolling assembly and the paved ground changes synchronously to ensure that when the paving thickness of the road changes, the rolling assembly always maintains a rolling state for the paving material, and can adapt to the paving work of roads of different thicknesses.

[0037] It should be noted that the paving material contained in the material box 2 is a curing agent made of industrial waste and soft soil in the site, which are mixed in a certain proportion.

[0038] As a further solution to this problem, please refer to Figure 7 The conducting structure includes a symmetrically arranged deflection shaft 3, which is rotatably installed at the bottom of the discharge box 2 and passes through the discharge box 2. The two deflection shafts 3 are rotatably connected through a gear set 5. A baffle 4 is rotatably connected to the deflection shaft 3, and the side end of the baffle 4 abuts against the inner wall of the discharge end.

[0039] Preferably, when the discharge end is in a closed state, the two baffles 4 abut against each other at their ends away from the deflection shaft 3 .

[0040] Among them, under the action of the gear set 5, the rotation directions of the two deflection shafts 3 are always opposite, so that when the baffle 4 rotates, the gap between the two baffles 4 changes, and the paving material in the discharge box 2 falls onto the paved road through this gap. The amount of paving material falling depends on the size of the gap between the two baffles 4. By changing the gap between the two baffles 4, the thickness of the road pavement can be changed.

[0041] As a further solution to this problem, please refer to Figure 3 、 Figure 5 and Figure 6 The rolling assembly includes telescopic parts symmetrically arranged at the bottom of the frame 1 and a rolling wheel 11 rotatably installed between the two telescopic parts.

[0042] The telescopic member includes a connecting tube 13 and a connecting plate 12. One end of the connecting tube 13 is fixedly connected to the frame 1, and a connecting plate 12 is slidingly provided inside the other end. The end of the connecting plate 12 away from the connecting tube 13 is rotatably connected to the rotating shaft of the rolling wheel 11.

[0043] As a further solution to this problem, please refer to Figure 6 The threaded pusher includes a bidirectional screw rod 7 rotatably mounted on the frame 1, one of the bidirectional screw rods 7 is driven to rotate by a first motor 6 fixedly mounted on the frame 1, and the other bidirectional screw rod 7 is rotatably connected to one of the deflection shafts 3 through a second bevel gear set 16, and a threaded sleeve 8 is symmetrically provided on the bidirectional screw rod 7, and the threaded sleeve 8 is threadedly connected to the bidirectional screw rod 7 and is slidably connected to the frame 1;

[0044] It also includes adjusting pieces symmetrically arranged at both ends of the rotating shaft of the rolling wheel 11, and the other end of the adjusting piece is connected to the threaded sleeve 8.

[0045] The adjusting member includes a first hinge plate 9 and a second hinge plate 10, wherein the first hinge plate 9 and the second hinge plate 10 are both arranged in an inclined structure;

[0046] One end of the first hinged plate 9 is rotatably connected to one of the threaded sleeves 8, and the other end is rotatably connected to the rotating shaft of the rolling wheel 11. One end of the second hinged plate 10 is rotatably connected to the other threaded sleeve 8, and the other end is rotatably connected to the rotating shaft of the rolling wheel 11.

[0047] Preferably, a connecting shaft 15 is rotatably mounted on the vehicle frame 1 , and both ends of the connecting shaft 15 are rotatably connected to the two bidirectional screw rods 7 via symmetrically arranged first bevel gear sets 14 .

[0048] To elaborate, after the frame 1 moves to the designated paved section, the first motor 6 is started. When the first motor 6 is working, it controls the rotation of the output shaft. The output shaft is fixedly connected to one of the two-way screw rods 7, so that one of the two-way screw rods 7 rotates synchronously with the rotation of the output shaft. When the two-way screw rod 7 rotates, it drives the two threaded sleeves 8 to make linear motion along the axial direction of the two-way screw rod 7. The moving directions of the two threaded sleeves 8 always remain opposite. When the two threaded sleeves 8 move, they squeeze the first hinge plate 9 and the second hinge plate 10 respectively, so that the positions of the first hinge plate 9 and the second hinge plate 10 change. Under the restriction of the connecting plate 12 and the connecting tube 13, the height of the rolling wheel 11 and the ground changes, so that when the paving thickness of the road changes, the rolling wheel 11 always keeps the paving material in a rolling state.

[0049] As a further solution to this problem, please refer to Figure 3 and Figure 4 The greenway road paving device for stabilizing soil pavement also includes an adjustable transmission member arranged at the bottom of the frame 1, and the adjustable transmission member includes a transmission shaft 22, and a first connecting plate 23 and a second connecting plate 24 are sleeved on the transmission shaft 22. The end of the first connecting plate 23 away from the transmission shaft 22 is rotatably connected to the rotating shaft of the rolling wheel 11, and the end of the second connecting plate 24 away from the transmission shaft 22 is rotatably connected to the drive shaft 18 rotatably installed at the bottom of the frame 1. The rotating shaft of the rolling wheel 11 and the transmission shaft 22 are rotatably connected by a third belt 21, and the drive shaft 18 and the transmission shaft 22 are rotatably connected by a second belt 20.

[0050] Preferably, two wheels are installed at the bottom of the frame 1, and a main wheel shaft 17 rotatably connected to the frame 1 is installed between the two wheels. The main wheel shaft 17 is rotatably connected to the drive shaft 18 through a first belt 19.

[0051] It should be noted that: the drive shaft 18 is connected to a drive member fixedly mounted on the bottom of the frame 1. The drive member can adopt a second motor. The drive shaft 18 is driven to rotate by the second motor. The second motor is connected to a control unit. The working time of the second motor is controlled by the control unit. The control unit includes but is not limited to a control button and an integrated circuit board mounted on the frame 1. The method of controlling the motor is a conventional design and is not specifically limited in this embodiment.

[0052] Specifically, when the frame 1 moves, the second motor controls the rotation of the drive shaft 18. When the drive shaft 18 rotates, under the action of the first belt 19 and the second belt 20, the main wheel shaft 17 and the transmission shaft 22 are driven to rotate respectively. When the transmission shaft 22 rotates, under the action of the third belt 21, the crushing wheel 11 is driven to rotate, so that the wheel and the crushing wheel 11 can rotate synchronously. Moreover, under the action of the first connecting plate 23 and the second connecting plate 24, when the vertical position of the crushing wheel 11 changes, it is ensured that the crushing wheel 11 and the wheel always maintain a synchronous rotation state, and at the same time, the crushing wheel 11 always maintains a crushing state on the ground.

[0053] In the initial state, the discharge end of the discharge box 2 is in a closed state, and the rolling wheel 11 is in contact with the ground.
