DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] First, see Figures 1 to 5 The utility model provides a roadbed compacting device, including a compacting vehicle 01, on which a compacting lifting assembly and a compacting roller 02 are provided; the compacting lifting assembly includes a lifting box 03, a transmission screw 05, a lifting support plate 06, a limit slider 07 and a connecting slider 08; a transmission screw 05 is provided inside the lifting box 03, and the bottom end of the transmission screw 05 is rotatably connected to the inner bottom wall of the lifting box 03; the lifting support plate 06 is sleeved on the transmission screw 05 and threadedly connected to the transmission screw 05, and limit sliders 07 are provided on both sides of the lifting support plate 06, and the lifting support plate 06 is slidably connected to the inner wall of the lifting box 03 through the limit slider 07; a connecting slider 08 is provided at the front end of the lifting support plate 06, and the end of the connecting slider 08 away from the lifting support plate 06 is connected to the compacting roller 02.

[0035] The roadbed compacting device provided by the present invention, when it is necessary to adjust the position of the compacting roller 02 according to the actual road surface compaction demand, by rotating the transmission screw 05 and due to the limitation of the limit slider 07, the transmission screw 05 rotates and the lifting support plate 06 moves on the transmission screw 05, and the up and down movement of the lifting support plate 06 drives the connecting slider 08 to move up and down, and the connecting slider 08 is used to drive the compacting roller 02 to move up and down together. Through this device, the position of the compacting roller 02 can be adjusted accordingly according to the road surface height, thereby meeting the compaction needs of different road surfaces.

[0036] Furthermore, the roadbed compacting device may further include a first motor, the first motor 04 being disposed on the top of the lifting box 03, the output end of the first motor 04 passing through the top of the lifting box 03 and mechanically connected to the top end of the transmission screw 05, and the bottom end of the transmission screw 05 being rotatably connected to the inner bottom wall of the lifting box 03;

[0037] The present invention does not limit the connection method between the first motor 04 and the transmission screw 05. Optionally, they can be directly connected or connected through a coupling.

[0038] Among them, the operation of the first motor 04 is used to drive the transmission screw 05 to rotate, and as the transmission screw 05 rotates, the position of the compaction roller 02 is raised and lowered. In this way, the position of the compaction roller 02 is moved to a suitable height, thereby meeting the roadbed compaction requirements in different situations.

[0039] It can be understood that the compacting vehicle 01 has moving wheels 36 and is capable of traveling along the roadbed to be compacted.

[0040] In one embodiment, the device further comprises a mounting frame 09, a connecting rod 10, and a connecting and fixing frame 11. Both ends of the compacting roller 02 are mounted on the mounting frame 09 via rotating shafts. The upper end of the mounting frame 09 is fixedly connected to one end of the connecting rod 10, and the other end of the connecting rod 10 is connected to the connecting and fixing frame 11. The connecting and fixing frame 11 is sleeved onto the connecting slider 08. The rotation of the drive screw 05 allows the compacting roller 02 to be raised and lowered via the mounting frame 09, further improving the accuracy of controlling the height of the compacting roller 02.

[0041] Further, see Figure 6 , both ends of the inner top wall of the mounting frame 09 are respectively provided with clamping components; the clamping assembly includes a base 12, a compression spring 13, a support arm 14, an arc plate 15, a bracket 16 and a pressure roller 17; the base 12 is fixedly connected to the inner top wall of the mounting frame 09, one end of the compression spring 13 is fixedly connected to the bottom of the base 12, and the other end of the compression spring 13 is fixedly connected to the support arm 14; the end of the support arm 14 away from the compression spring 13 is fixedly connected to the arc plate 15, the inner wall of the arc plate 15 is fixedly connected to the bracket 16, and a pressure roller 17 is rotatably connected to the bracket 16, and the pressure roller 17 is in contact with the compacting roller 02.

[0042] The compression spring 13 is a load-bearing compression spring. Optionally, the compression spring 13 is a hydraulic spring type motorcycle shock absorber.

[0043] By adding a clamping assembly to the compacting roller 02, when the compacting lifting assembly is adjusted to the specified height according to the road surface height, the lifting support plate 06 can be further lowered, and the elastic potential energy generated by the compression spring 13 can be used to apply downward pressure to the compacting roller 02, thereby further increasing the downward pressure of the compacting roller 02 and further improving the roadbed compaction effect.

[0044] In a specific embodiment, a hanger 18 is further provided at the center of the inner top wall of the mounting frame 09; a cavity 19 is opened at the lower end of the hanger 18, a waste box 20 is clamped on one side of the cavity 19, and a scraper 21 is provided at the end of the hanger 18 close to the cavity 19, and the scraper 21 is in contact with the compaction roller 02.

[0045] By making the blade 21 contact the surface of the compaction roller 02, the compaction roller 02 can be cleaned in time, further improving the compaction effect of the roadbed compaction device.

[0046] Further, see Figures 1 to 4 and Figure 7, a cleaning assembly and a cleaning lifting assembly are also provided at the front end of the compacting vehicle 01 along the direction of travel; the cleaning lifting assembly includes a support plate 22, a limit frame 23, a transmission shaft 25, an output gear 26, an internally threaded sleeve 27 and a telescopic screw 28; a limit frame 23 is provided on the top of the support plate 22, and a transmission shaft 25 is provided inside the limit frame 23, one end of the transmission shaft 25 is connected to the output gear 26, and the outer side of the internally threaded sleeve 27 is fixedly connected to the transmission gear 33, and the output gear 26 is meshed with the transmission gear 33; the telescopic screw 28 is threadedly sleeved inside the internally threaded sleeve 27, and when the internally threaded sleeve 27 rotates, it drives the telescopic screw 28 to perform telescopic activities inside it; the bottom of the telescopic screw 28 is connected to the cleaning assembly.

[0047] In a specific embodiment, the cleaning lifting assembly further includes a second motor 24 . The second motor 24 is disposed on the top of the limiting frame 23 , and an output end of the second motor 24 is connected to the transmission shaft 25 .

[0048] It can be understood that before the compacting roller 02 compacts the road surface, the operation of the second motor 24 can cause the cleaning component to descend together. After the cleaning component descends to the ground, as the compacting vehicle 01 body is pushed, the cleaning component cleans the gravel on the road surface, further improving the compaction effect.

[0049] Specifically, see Figure 8 and Figure 9 The cleaning component includes a cleaning shell 29, a cleaning brush 30 and an adsorption component; the adsorption component includes a suction port 31, a bellows 32, a vacuum pump and a collection container; the suction port 31 is located at both ends of the cleaning brush 30, and the suction port 31 is connected to the bellows 32, and the end of the bellows 32 away from the suction port 31 is connected to the inlet of the vacuum pump, and the outlet of the vacuum pump is connected to the collection container outside the compacting vehicle 01 through a pipeline.

[0050] An adsorption component is provided on one side of the cleaning brush 30 to absorb loose gravel and improve the cleaning effect.

[0051] See also Figures 1 to 4 and Figures 7 to 9The second motor 24 is driven to rotate the transmission shaft 25. The rotation of the transmission shaft 25 causes the output gear 26 to rotate, further driving the transmission gear 33 to rotate. Synchronously, the internally threaded sleeve 27 rotates along with the transmission gear 33, causing the telescopic screw 28 to extend and retract within the internally threaded sleeve 27, thereby adjusting the height of the cleaning assembly. The cleaning assembly is lowered so that the bottom end of the cleaning brush 30 can be lowered to the ground. At this time, the compacting vehicle 01 is pushed forward, and the cleaning brush 30, along with the compacting vehicle 01, sweeps away the gravel on the road surface. At the same time, the suction components on both sides of the cleaning brush 30 absorb the swept gravel. This method allows the compacting roller 02 to remove the gravel before compacting the road surface, preventing the gravel from affecting the road compaction operation.

[0052] In one embodiment, the compacting vehicle 01 is further provided with a control component; the control component is in communication connection with the first motor 04 and / or the second motor 24 .

[0053] Among them, the control component includes a control box 35 and a control panel 34. The control panel 34 is used to receive input signals from the operator and control the operation of each actuator. The utility model is not limited to a specific control system, and the control system can adopt a system that can realize the control function in the existing technology.

[0054] Furthermore, the first motor 04 and / or the second motor 24 is a servo motor.

[0055] When in use, start the second motor 24, and use the cleaning lifting component to adjust the cleaning component to the corresponding position according to the road surface height to perform cleaning; start the first motor 04, and use the compaction lifting component to adjust the compaction roller 02 to the corresponding position according to the road surface height; start the compaction vehicle 01 to compact the roadbed.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
