DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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.

[0020] First, see Figure 1~Figure 5 The present invention provides a roadbed compacting device, including a compacting vehicle 01, on which a compacting lifting assembly and a compacting roller 02 are arranged; the compacting lifting assembly includes a lifting box 03, a first motor 04, a transmission screw 05, a lifting support plate 06, a limit slider 07 and a connecting slider 08; the first motor 04 is arranged at the top of the lifting box 03, the output end of the first motor 04 passes through the top of the lifting box 03 and is mechanically connected to the top of the transmission screw 05, 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 is threadedly connected to the transmission screw 05, and both sides of the lifting support plate 06 are provided with limit sliders 07, and the lifting support plate 06 is slidably connected to the inner wall of the lifting box 03 through the limit slider 07; the front end of the lifting support plate 06 is provided with a connecting slider 08, and the end of the connecting slider 08 away from the lifting support plate 06 is connected to the compacting roller 02.

[0021] 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.

[0022] The operation of the first motor 04 is utilized to drive the transmission screw 05 to rotate, and the position of the compaction roller 02 is moved up and down as the transmission screw 05 rotates. 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.

[0023] The roadbed compaction device provided by the present invention can rotate the transmission screw 05 through the operation of the first motor 04 when the position of the compaction roller 02 needs to be adjusted according to the actual road surface compaction demand, and due to the limitation of the limit slider 07, the lifting support plate 06 moves on the transmission screw 05 when the transmission screw 05 rotates, 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 compaction roller 02 to move up and down together. Through this device, the position of the compaction roller 02 can be adjusted accordingly according to the road surface height, thereby meeting the compaction requirements of different road surfaces.

[0024] It can be understood that the compacting vehicle 01 has moving wheels 36 and can move along the roadbed to be compacted.

[0025] In a specific embodiment, it also includes: a mounting frame 09, a connecting rod 10 and a connecting and fixing frame 11; both ends of the compacting roller 02 are set on the mounting frame 09 through a rotating shaft, 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, and the connecting and fixing frame 11 is sleeved on the connecting slider 08. The position of the compacting roller 02 is moved up and down by the rotation of the transmission screw 05 using the mounting frame 09, further improving the accuracy of controlling the height of the compacting roller 02.

[0026] For further information, see Figure 6 , clamping assemblies are also provided at both ends of the inner top wall of the mounting frame 09; 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; one 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 compaction roller 02.

[0027] The compression spring 13 is a load-bearing compression spring. Optionally, the compression spring 13 is a hydraulic spring type motorcycle shock absorber.

[0028] 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.

[0029] In a specific embodiment, a hanger 18 is also 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 one end of the hanger 18 close to the cavity 19, and the scraper 21 is in contact with the compaction roller 02.

[0030] By making the blade 21 contact with 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.

[0031] For further information, see Figure 1~Figure 4 and Figure 7A cleaning assembly and a cleaning lifting assembly are also provided at the front end of the compacting vehicle 01 along the traveling direction; the cleaning lifting assembly includes a support plate 22, a limit frame 23, a second motor 24, 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, a second motor 24 is provided on the top of the limit frame 23, an output end of the second motor 24 is connected to the transmission shaft 25, one end of the transmission shaft 25 is connected to the output gear 26, a transmission gear 33 is fixedly connected to the outer side of the internally threaded sleeve 27, and the output gear 26 is meshedly connected to the transmission gear 33; the telescopic screw 28 is threadedly sleeved in the interior of the internally threaded sleeve 27, and when the internally threaded sleeve 27 rotates, it drives the telescopic screw 28 to perform telescopic activities in the interior thereof; the bottom of the telescopic screw 28 is connected to the cleaning assembly.

[0032] 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.

[0033] Specifically, see Figure 8 and Fig. 9 The cleaning component includes a cleaning shell 29, a cleaning brush 30 and an adsorption component; the adsorption component includes an adsorption port 31, a bellows 32, a vacuum pump and a collecting container; the adsorption port 31 is located at both ends of the cleaning brush 30, and the adsorption port 31 is connected to the bellows 32, and the end of the bellows 32 away from the adsorption port 31 is connected to the inlet of the vacuum pump, and the outlet of the vacuum pump is connected to the collecting container outside the compacting vehicle 01 through a pipeline.

[0034] A suction component is provided on one side of the cleaning brush 30 to absorb loose gravel and improve the cleaning effect.

[0035] See also Figure 1~Figure 4 and Figure 7~Figure 9 The second motor 24 can rotate the transmission shaft 25, and the output gear 26 can rotate with the rotation of the transmission shaft 25, which further drives the transmission gear 33 to rotate. The internal threaded sleeve 27 rotates synchronously with the transmission gear 33, so that the telescopic screw 28 can be telescoped inside the internal threaded sleeve 27, so as to achieve the height adjustment of the cleaning component. The cleaning component is adjusted to be 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, and the cleaning brush 30 will clean the gravel on the road surface with the push of the compacting vehicle 01, and at the same time, the adsorption components on both sides of the cleaning brush 30 can adsorb the cleaned gravel. In this way, the compacting roller 02 can clean the gravel before compacting the road surface, so as to prevent the gravel from affecting the road surface compaction operation.

[0036] In one embodiment, a control component is further provided on the compacting vehicle 01 ; the control component is communicatively connected with the first motor 04 and / or the second motor 24 .

[0037] The control assembly 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 present invention does not limit the specific control system. The control system can adopt any system that can realize the control function in the prior art.

[0038] Furthermore, the first motor 04 and / or the second motor 24 is a servo motor.

[0039] In a second aspect, the present invention provides a roadbed compaction method, which is performed using the above-mentioned roadbed compaction device.

[0040] In one embodiment, the following steps are included: S1: starting the first motor 04, and adjusting the compaction roller 02 to a corresponding position according to the road surface height by using the compaction lifting assembly; S2: Start compaction vehicle 01 to compact the roadbed.

[0041] Furthermore, before step S1, the method further includes: starting the second motor 24, adjusting the cleaning component to a corresponding position using the cleaning lifting component according to the height of the road surface, and performing cleaning processing.
