Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road rollers, in particular to a road roller with a telescopic expansion wheel. Background Art
[0002] A road roller, also known as a soil roller, is an indispensable and important equipment in road construction. A road roller is usually equipped with a heavy pressure wheel. When working, the road roller pushes the pressure wheel to roll along the ground to squeeze the ground to make it flat. There are many types of road rollers on the market, and most of them are usually only equipped with one pressure wheel.
[0003] However, when this type of roller with only one pressing wheel is in use, a single movement can only perform ground squeezing operations on a certain line. When it is necessary to squeeze the ground on two lines at the same time, the roller needs to go back and forth at least once to complete the squeezing operations on the two lines. In addition, when there are obstacles between the two lines, such as stone bricks on the ground, the distance between the extended pressing wheel and the main pressing wheel cannot be adjusted to avoid the obstacles for squeezing operations, which brings inconvenience to the user. In view of this, we propose a roller with a telescopic extended pressing wheel. Utility Model Content

A U-shaped frame 26 is provided on the telescopic shaft of the second hydraulic cylinder 251, and an extended pressure wheel 261 is rotatably connected between the left and right side plates of the U-shaped frame 26, so that the main pressure wheel 11 and the extended pressure wheel 261 can be used to press against the ground at the same time to perform extrusion operations on two lines.
[0026] In this embodiment, a vertical plate 201 is fixedly installed on the bottom surface of the steel plate 20, and a pressure-resistant plate 21 is fixedly installed between the vertical plate 201 and the storage arm 22, so as to facilitate further pressure-resistant support operation on the storage arm 22 by using the pressure-resistant plate 21, making the structure of the storage arm 22 more firm and stable.
[0027] Specifically, a storage chamber 221 communicated with the outside is provided in the storage arm 22 , and the extension arm 24 is located in the storage chamber 221 and is slidably connected to the storage chamber 221 , so as to achieve the effect of storing the extension arm 24 .
[0028] Furthermore, a sliding hole 222 is provided on the top wall of the storage chamber 221, and the end of the sliding hole 222 is not connected to the outside world.

When the first hydraulic cylinder 23 works, the telescopic shaft thereon extends or shortens to drive the protrusion 241 and the outward extension arm 24 to move forward or backward, thereby adjusting the horizontal distance between the main roller 11 and the extension roller 261. After the distance is adjusted, the second hydraulic cylinder 251 is started and made to work. When the second hydraulic cylinder 251 works, the telescopic shaft thereon extends to drive the U-shaped frame 26 and the extension roller 261 to move downward. The extension roller 261 is pressed downward against the ground, and then in cooperation with the work of the roller body 1, the main roller 11 and the extension roller 261 are driven to roll along the ground to perform compaction operations.
