Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example one

The embodiment discloses a modified rubber-tyred roller, as shown in fig. 1, the rubber-tyred roller includes a roller body a, i.e., a control part of the roller, and a rubber-tyred group B, i.e., an advancing and working part of the roller, where the rubber-tyred group B is installed at both front and rear ends of the roller body a, and generally includes 4-6 rubber wheels (tires), and an oil brush assembly C is installed on each rubber wheel.

The oil brush component C is the key point for improving the road roller. The oil brush assembly C comprises a first brush head assembly C1 and a second brush head assembly C2, wherein the first brush head assembly C1 and the second brush head assembly C2 are respectively arranged at the front side and the rear side of the rubber wheel. The oil brush assembly C is configured to: at the same time, only the brush head assembly at the running direction side of the roller is contacted with the corresponding rubber wheel in the first brush head assembly C1 and the second brush head assembly C2. It should be noted that this is a description of the state of the roller when it is moving, and that the brush head assembly in contact with the rubber wheel is the same as the moment before the roller is stopped when the roller is not moving (including when it is started but not moving).

Example two

Based on the design idea of the first embodiment, the embodiment discloses a modified rubber-tyred road roller.

As shown in fig. 2, 3 and 4, the oil brush assembly C includes a first brush head assembly C1, a second brush head assembly C2, a first guide assembly, a second guide assembly and an adjustment assembly. The first brush head component C1 and the second brush head component C2 are respectively movably connected with the adjusting component. The adjusting component is a device for adjusting which brush head component is contacted with the rubber wheel, and only one adjusting component is contacted with the rubber wheel at the same time. The first guide assembly is used to fix the direction of movement-in the axial direction-of the first brushhead assembly C1, and the second guide assembly is used to fix the direction of movement-in the axial direction-of the second brushhead assembly C2. The adjustment assembly then simultaneously retracts first brushhead assembly C1 and pushes second brushhead assembly C2 (i.e., first brushhead assembly C1 is retracted, second brushhead assembly C2 is pushed into contact with the rubber wheel), or, alternatively, pushes first brushhead assembly C1 and retracts second brushhead assembly C2 (i.e., second brushhead assembly C2 is retracted, first brushhead assembly C1 is pushed into contact with the rubber wheel).

The synchronized adjustment of the first brushhead assembly C1 and the second brushhead assembly C2 described above can be accomplished through a lever principle. The adjusting assembly is designed to include an adjusting lever 31 and a rotating shaft 32, and the middle portion of the adjusting lever 31 is fixed to the rotating shaft 32, and the two are perpendicular to each other. The range of rotation of the adjustment lever 31 needs to be limited to a certain extent to avoid excessive rotation and excessive contact of the brushhead assembly with the rubber wheel, or it can be understood that the brushhead assembly just contacts the rubber wheel. The first brush head assembly C1 and the second brush head assembly C2 are slidably connected to the adjustment lever 31, respectively, to move in respective axial directions when the adjustment lever 31 is rotated. The first brushhead assembly C1 and the second brushhead assembly C2 are positioned on opposite sides of the shaft 32, respectively, to move in opposite directions at the same time.

With respect to the above-mentioned manner of limiting the rotation range of the adjustment lever 31, in some embodiments, this is achieved by designing a stopper. The first stop 34 defines the maximum angle of rotation of the adjustment lever 31 in the direction of the first brushhead assembly C1, and the second stop 35 defines the maximum angle of rotation of the adjustment lever 31 in the direction of the second brushhead assembly C2. The first stop 34 and the second stop 35 may be designed independently or on the rotating shaft 32. It is apparent that the first stop 34 and the second stop 35 are located on the rotation path of the adjustment lever 31.

After the rubber wheel moves towards one direction, when the rubber wheel moves in the opposite direction, due to the contact relation and the adhesion property of an oil layer, the rubber wheel can drive the brush head assembly in contact with the rubber wheel to move in the opposite direction, the brush head assembly pushes the adjusting rod 31 to rotate under the driving of the rubber wheel until the balance point of the lever is reached, and due to inertia, the withdrawn brush head assembly can continuously push the adjusting rod 31, so that the other brush head assembly is pushed out to be in contact with the rubber wheel.

In order to make the brush head assembly switch more timely and reliable, the two ends of the adjusting rod 31 are also connected with a counterweight 33. The weight 33 may be designed as a sphere and connected to both ends of the adjusting rod 31 by a screw connection.

This example discloses one embodiment of the above-described brushhead assembly.

As shown in fig. 3 and 4, the first brush head assembly C1 includes a first brush head 11, a first connecting rod 12 and a first connecting ring 14 connected in sequence, the first connecting ring 14 is sleeved on the adjusting rod 31 to realize a slidable connection, the first connecting rod 12 is fixed by a first guiding assembly to move only in an axial direction, in some embodiments, the first guiding assembly is designed as a first sleeve 13, the first connecting rod 12 passes through the first sleeve 13, and the outer diameter of the first connecting rod 12 is slightly smaller than the inner diameter of the first sleeve 13.

The second brush head assembly C2 comprises a second brush head 21, a second connecting rod 22 and a second connecting ring 24 connected in sequence, the second connecting ring 24 is sleeved on the adjusting rod 31 to realize a slidable connection, the second connecting rod 22 is fixed by a second guiding assembly to move only along the axial direction, in some embodiments, the second guiding assembly is designed as a second sleeve 23, the second connecting rod 22 passes through the second sleeve 23, and the outer diameter of the second connecting rod 22 is slightly smaller than the inner diameter of the second sleeve 23.

The first brush head 11 and the second brush head 21 are consumables and need to be replaced after use, so that the first brush head 11 is designed to be detachably connected with the first connecting rod 12 (for example, connected by a threaded connection mode), and the second brush head 21 is designed to be detachably connected with the second connecting rod 22, so that the replacement at a later stage is facilitated.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
