Description

TECHNICAL FIELD

[0001] The utility model relates to road roller accessory field, concretely refers to a kind of slip road roller accessory. BACKGROUND

[0002] Road roller is also called earth presser, and is a kind of road repairing equipment. It mainly drives steel wheel to vibrate and compact road surface by setting eccentric shaft in the steel wheel. It is widely used in filling and compacting operation of large engineering projects such as high-grade highway, railway, airport runway, dam and stadium, and can roll and compact sandy, semi-cohesive and cohesive soil, roadbed stable soil and asphalt concrete pavement layer. Road roller is suitable for various compacting operations by using the gravity of the machine itself, so that the compacted layer is permanently deformed and compacted.

[0003] At present, the road roller accessory is assembled on the slip machine to form a road roller for road rolling. The vibration frequency of the steel wheel is increased by increasing the rotation speed of the eccentric shaft, so as to improve the flattening effect of the road surface and avoid the appearance of road surface indentation. However, when the steel wheel vibrates at high frequency to compact the road surface, the vibration will extend to the front and rear sides of the road surface, thereby threatening to crack the road surface on the rear side which has been compacted.

[0004] In view of the problems existing in the prior art, the utility model provides a slip road roller accessory which can effectively solve the problems existing in the prior art. UTILITY MODEL CONTENTS

[0005] In view of the problems existing in the prior art, the utility model provides a slip road roller accessory which can effectively solve the problems existing in the prior art.

[0006] The technical scheme of the utility model is as follows:

[0007] A slip road roller accessory comprises:

[0008] A shell is internally provided with an eccentric shaft driven by a first driving device to rotate forward and backward, and a roller is arranged on the outer side of the eccentric shaft in a linkage mode. The bottom of the shell is provided with an opening to expose the roller.

[0009] A damping mechanism comprises an annular damping belt arranged on the rear side of the roller and driven by a second driving device to rotate forward and backward, and a damping cylinder arranged on the inner side of the damping belt and rolling against the inner bottom of the damping belt at the bottom. The damping cylinder is used to absorb vibration and is arranged side by side with a plurality of damping cylinders. The damping belt is used to rotate and adhere to the road surface and transmit vibration to the plurality of damping cylinders.

[0010] Further, the second driving device comprises two transmission wheels extending left and right and arranged side by side front and back, connecting plates respectively connected to the same ends of the left and right sides of the two transmission wheels, a second motor arranged on the inner side of the damping belt and used for driving the two transmission wheels to rotate, the damping belt is rotatably sleeved on the outer side of the two transmission wheels and has a left and right width matched with the left and right width of the roller, and a plurality of damping cylinders are arranged extending left and right and arranged side by side front and back, and the left and right ends of the plurality of damping cylinders are rotatably connected to the two connecting plates respectively.

[0011] Further, a plurality of telescopic driving devices are arranged on the inner rear side of the shell and are rotatably connected to the two connecting plates; the plurality of telescopic driving devices are used for lifting the damping mechanism to be arranged in the air or lowering the damping mechanism to abut against the road surface at the outer bottom of the damping belt, and the outer bottom of the damping belt is pressed to drive the telescopic ends of the plurality of telescopic driving devices to be telescopic.

[0012] Further, the plurality of telescopic driving devices are all air cylinders and are distributed on the left and right sides of the damping mechanism, and a first scraper extending downward and inclined at the front end is rotatably arranged between the cylinder bodies of the two corresponding air cylinders, a support plate is fixedly supported on the rear bottom of the first scraper, the lower end of the first scraper is provided as a flexible part used for scraping, and a plurality of springs are connected between the top of the first scraper and the shell; when the telescopic driving devices lift the damping mechanism, the flexible part of the first scraper is flexibly abutted against the top of the damping belt, and when the telescopic driving devices lower the damping mechanism, the first scraper is separated from the damping belt.

[0013] Further, the damping cylinder is made of damping material.

[0014] Further, the eccentric shaft comprises a rotating shaft and an eccentric wheel fixedly sleeved on the outer side of the rotating shaft.

[0015] Further, a second scraper is detachably arranged on the inner front side of the shell, the height of the second scraper gradually decreases from front to back, and the rear end of the second scraper abuts against the outer wall of the roller.

[0016] Further, a slide shovel part is arranged on the front part of the shell and is recessed, and the bottom of the slide shovel part is arranged to be spaced apart from the road surface.

[0017] Therefore, the utility model provides the following effects and / or advantages:

[0018] 1. By adding a vibration damping mechanism, the eccentric shaft rotates to drive the roller to vibrate at high frequency to compact the road surface. When there is a large vibration propagating backward, the vibration can be transmitted to several vibration damping cylinders by rotating the vibration damping belt that is attached to the road surface behind the roller. This prevents the road surface behind the roller, which has already been compacted, from being subjected to high-frequency vibration again and cracking. Under the premise of ensuring that the roller can improve the road compaction effect through high-frequency vibration, the vibration damping effect on the road surface behind the roller is achieved, thereby improving the stability of the sliding roller attachment.

[0019] 2. The vibration of the rollers pressing the road surface backward can be fully absorbed and transmitted to several vibration damping cylinders by the vibration damping belt with appropriate width. By extending several vibration damping cylinders to the left and right and arranging them side by side, the contact area between them and the vibration damping belt is increased, thereby improving the absorption efficiency of the vibration transmitted by the vibration damping belt. Together, this improves the vibration damping effect of the vibration damping mechanism on the road surface behind the rollers.

[0020] 3. By setting up a telescopic drive device, the vibration damping mechanism can be raised to a suspended position when it is not needed in the early stage of road rolling, thus avoiding unnecessary work and a reduction in service life. When the vibration damping mechanism is needed in the later stage of road rolling, it can be lowered to the bottom of the damping belt to contact the road surface, thus protecting the road surface behind the roller and improving the adaptability of the vibration damping mechanism to multiple working scenarios. At the same time, after the vibration damping mechanism is lowered, the air pressure inside the telescopic drive device is balanced, the telescopic end is not driven by power and can extend and retract freely. At this time, the vibration damping mechanism is in contact with the road surface under its own weight and rolls forward under the rotation of the two drive wheels. After the bottom of the damping belt contacts the road surface, it is pressed and drives the telescopic ends of several telescopic drive devices to extend and retract, so that the damping belt can always keep in contact with the road surface with the undulations of the road surface. This ensures that the damping belt can always transmit the vibration of the road surface behind the roller to several damping cylinders for absorption and damping, further improving the adaptability of the vibration damping mechanism.

[0021] 4. With the addition of the first scraper, when the vibration damping mechanism is lifted by the telescopic drive device, the flexible part of the first scraper flexibly abuts against the top of the vibration damping belt. After the second motor drives the vibration damping belt to rotate forward several times, the flexible part of the first scraper completes the scraping of the material on the outer wall of the vibration damping belt. Some of the scraped material accumulates on the top of the vibration damping belt. Then, the vibration damping mechanism is lowered by the telescopic drive device until the first scraper is separated from the vibration damping belt. After the second motor drives the vibration damping belt to rotate, the material accumulated on the top of the vibration damping belt is discharged onto the road surface, completing the cleaning of the outer wall of the vibration damping belt. This ensures the vibration damping stability of the vibration damping mechanism and extends the service life of the vibration damping belt.

[0029] In order to facilitate the understanding of those skilled in the art, the structure of the utility model will be further described in detail in combination with the drawings:

[0030] Reference Figures 1-6 A slip road roller, comprising:

[0031] A shell 1, which is internally provided with an eccentric shaft 11 driven by a first driving device to rotate forward and backward, and a roller 12 arranged on the outer side of the eccentric shaft 11 in linkage, the bottom of the shell 1 is provided with an opening to expose the roller 12, and the rear part of the shell 1 is used to be detachably mounted on a corresponding slip vehicle, the first driving device is an electric motor, and the roller 12 is a hollow steel wheel.

[0032] A damping mechanism 2, which comprises an annular damping belt 21 arranged on the rear side of the roller 12 and driven by a second driving device 23 to rotate forward and backward, and a damping cylinder 22 arranged on the inner side of the damping belt 21 and rolling against the bottom of the damping belt 21, the damping cylinder 22 is used to absorb vibration and is arranged side by side with a plurality of damping cylinders 22; the damping belt 21 is used to rotate and adhere to the road surface and transmit vibration to the plurality of damping cylinders 22.

[0033] The above structure is provided by adding the damping mechanism 2, so that the eccentric shaft 11 drives the roller 12 to vibrate at high frequency to compact the road surface, when there is a large vibration propagating backward, the vibration can be transmitted to the plurality of damping cylinders 22 through the damping belt 21 rotating and adhering to the road surface on the rear side of the roller 12 to be absorbed and damped, thereby avoiding the situation that the road surface on the rear side of the roller 12, which has been compacted, is cracked again by high-frequency vibration, realizing the damping effect on the rear side of the road surface under the premise of ensuring that the roller 12 can improve the road compaction effect by high-frequency vibration, and improving the use stability of the slip road roller.

[0034] In order to improve the damping effect of the damping mechanism 2, the second driving device 23 includes two left and right extending and front and rear parallel transmission wheels 231, a connecting plate 232 connected to the same end of the left and right sides of the two transmission wheels 231, respectively, a second motor arranged inside the damping belt 21 and used to drive the two transmission wheels 231 to rotate, the damping belt 21 is rotatably sleeved outside the two transmission wheels 231 and the left and right widths of the damping belt 21 are adapted to the left and right widths of the roller 12, and a plurality of damping cylinders 22 are arranged left and right extending and front and rear parallel, and the left and right ends of the plurality of damping cylinders 22 are rotatably connected to the two connecting plates 232, respectively. Thus, the vibration conducted by the roller 12 to the rear road surface can be fully absorbed by the damping belt 21 with an appropriate width and conducted to the plurality of damping cylinders 22, and by arranging the plurality of damping cylinders 22 left and right extending and front and rear parallel, the contact area with the damping belt 21 is increased, so as to improve the absorption efficiency of the vibration conducted by the damping belt 21, and the damping effect of the damping mechanism 2 on the vibration of the rear road surface of the roller 12 is improved.

[0035] In the early stage of road rolling, the road surface is still relatively uneven, and the soil or asphalt material of the road surface is still relatively loose, the road surface is not easy to crack, and the damping mechanism 2 is not needed to be used for damping, and in the later stage of road rolling, the road surface density is large after the road rolling tool is rolled for a certain number of times, and the damping mechanism 2 is needed to be used for protecting the road surface behind the roller 12 from cracking, therefore, in order to improve the adaptability of the damping mechanism 2, a plurality of telescopic driving devices 3 are arranged inside the rear side of the shell 1 and rotatably connected to the two connecting plates 232, and specifically, the telescopic driving device 3 is arranged as a single operation cylinder; thus, by arranging the telescopic driving device 3, the damping mechanism 2 can be lifted to be suspended when the damping mechanism 2 is not needed in the early stage of road rolling, so as to avoid the decrease of service life caused by excessive work of the damping mechanism 2, and the damping mechanism 2 can be lowered to abut against the road surface at the outer bottom of the damping belt 21 when the damping mechanism 2 is needed in the later stage of road rolling, so as to protect the road surface behind the roller 12 from damping and improve the adaptability of the damping mechanism 2 to multiple working scenes; at the same time, after the damping mechanism 2 is lowered, the air pressure in the telescopic driving device 3 is balanced, the telescopic end is not driven and can be freely telescoped, at this time, the damping mechanism 2 is attached to the road surface under the action of its own weight, and rolls towards the front side under the rotation of the two transmission wheels 231, the outer bottom of the damping belt 21 abuts against the road surface and drives the telescopic end of the plurality of telescopic driving devices 3 to telescope, so that the damping belt 21 can always be attached to the road surface along with the ups and downs of the road surface, thereby ensuring that the damping belt 21 can always conduct the vibration of the road surface behind the roller 12 to the plurality of damping cylinders 22 for absorption and damping, and further improving the adaptability of the damping mechanism 2.

[0036] Since the damping belt 21 needs to adhere to the road surface when the damping mechanism 2 is working, a certain amount of soil, asphalt and other substances will adhere to the damping belt 21, thereby affecting the damping effect. Therefore, in order to ensure the damping stability of the damping mechanism 2, the plurality of telescopic driving devices 3 are air cylinders and are distributed on the left and right sides of the damping mechanism 2. A first scraper 4 extending downward at the front end is rotatably arranged between the cylinder bodies of the two corresponding air cylinders on the left and right sides. A support plate 5 is fixedly supported on the rear bottom of the first scraper 4. The lower end of the first scraper 4 is provided with a flexible part 41 for scraping. A plurality of springs 6 are connected between the top of the first scraper 4 and the shell 1. When the damping mechanism 2 is lifted by the telescopic driving device 3, the flexible part 41 of the first scraper 4 flexibly abuts against the top of the damping belt 21. After the damping belt 21 is driven by the second motor to rotate forward for a few turns, the flexible part 41 of the first scraper 4 completes the scraping of the outer wall of the damping belt 21. Part of the scraped material is accumulated on the top of the damping belt 21. Then, the damping mechanism 2 is lowered by the telescopic driving device 3 until the first scraper 4 is separated from the damping belt 21. After the damping belt 21 is driven to rotate by the second motor, the material accumulated on the top of the damping belt 21 is discharged to the road surface, thereby completing the cleaning of the outer wall of the damping belt 21. Thus, the damping stability of the damping mechanism 2 is ensured and the service life of the damping belt 21 is prolonged.

[0037] Specifically, the damping cylinder 22 is made of damping material, such as damping composite material, high-damping alloy, etc. Damping material is a material that converts solid mechanical vibration energy into heat energy and dissipates it. It is mainly used for vibration and noise control. The damping performance of the material can be measured according to its ability to dissipate vibration energy. The standard for evaluating damping size is damping coefficient.

[0038] Specifically, the eccentric shaft 11 includes a rotating shaft 111 and an eccentric wheel 112 fixedly sleeved outside the rotating shaft 111.

[0039] In order to clean the soil, asphalt and other substances adhered to the outer wall of the roller 12, a second scraper 13 is detachably arranged on the inner side of the front part of the shell 1. The height of the second scraper 13 gradually decreases from front to back, and the rear end of the second scraper 13 abuts against the outer wall of the roller 12.

[0040] In order to clean the soil, asphalt and other substances protruding from the front side of the roller 12, a sliding shovel part 14 is arranged in the front part of the shell 1. The bottom of the sliding shovel part 14 is spaced apart from the road surface. Thus, the soil, asphalt and other substances protruding from the front side of the roller 12 are pushed and cleaned by the sliding shovel part 14.

[0041] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
