Description

Technical Field

[0001] The present invention discloses a vibrating wheel and a road roller for edge compaction, which relates to the technical field of compaction machinery. Background Art

[0002] At present, the working device of a typical light vibrating road roller in the industry is mainly used for vibrating compaction. The vibrating wheel is connected to the vehicle frame through a support plate, and the support plate extends out of the vibrating wheel in the width direction.

[0003] During operation, when the light vibrating road roller is moving forward, the vibrating wheel compacts the ground. However, when there are obstacles such as buildings, curbstones, plants, etc. beside the ground to be compacted, affected by the support plate, the vibrating wheel cannot achieve edge compaction.

[0004] The current common practice is to minimize the width of the support plate extending out of the vibrating wheel as much as possible, which improves the edge compaction ability to a certain extent, but still cannot achieve complete edge compaction. Summary of the Invention

[0005] Aiming at the defects in the above background art, the present invention provides a vibrating wheel and a road roller for edge compaction, which have good edge compaction ability.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: A vibrating wheel for edge compaction includes a main compaction wheel, a driving side support plate and a vibrating side support plate. The driving side support plate and the vibrating side support plate are respectively connected to both sides of the main compaction wheel. The driving side support plate is connected to a driving device to provide the driving force for the main compaction wheel to move. An exciter is arranged in the main compaction wheel for exciting vibration, and the vibrating side support plate is connected to a vibrating device to provide power for the exciter.

[0007] It further includes: an auxiliary compaction wheel, which is connected to the vibrating side of the main compaction wheel. The auxiliary compaction wheel and the bottom of the main compaction wheel are at the same height. The auxiliary compaction wheel extends out in the width direction relative to the main compaction wheel, and the width of the auxiliary compaction wheel exceeds the width of the vibrating side support plate extending out. During the compaction process, the auxiliary compaction wheel can make up for the width of the support plate extending out, which is beneficial to edge compaction.

[0008] Further, the fixed end of the driving device is connected to the driving side support plate, and the rotating end of the driving device is sequentially connected to the driving side of the main compaction wheel through a driving plate and a driving side shock absorber, so as to realize the driving device driving the main compaction wheel to rotate, that is, the walking function of the vibrating wheel.

[0009] Further, the main pressing wheel includes a rim, a left sealing plate, an inner ring, and a right sealing plate. The inner ring is coaxially and fixedly connected inside the rim. The rim is in the shape of a hollow cylinder. The inner ring is arranged in the center of the rim, separating both sides of the rim. Uncovered reserved spaces are formed between both sides of the inner ring and the rim. The left sealing plate and the right sealing plate are fixedly connected to both sides of the inner ring, and installation openings are reserved on the left sealing plate and the right sealing plate to facilitate the installation of the left vibration bearing seat and the right vibration bearing seat on both sides.

[0010] Further, the vibrator is arranged along the axial direction of the rotation axis of the main pressing wheel. Both ends of the vibrator are respectively supported on the left vibration bearing seat and the right vibration bearing seat through vibration bearings. The left vibration bearing seat and the right vibration bearing seat are coaxially and fixedly connected to both sides of the main pressing wheel. One end of the vibrator is connected with a spline sleeve, and the vibration device can transmit power to the vibrator through the spline sleeve, thus realizing the vibration function of the vibrating wheel. The vibration device adopts a vibration motor.

[0011] Further, the right vibration bearing seat is assembled with an inner ring of a frame bearing and is pressed tightly by a pressing plate. The outer ring of the frame bearing is assembled in the frame bearing seat and is pressed tightly by a motor connection disk. Through the inner ring of the frame bearing, the outer ring can rotate relatively. The right vibration bearing seat and the frame bearing seat realize relative rotation through the frame bearing. The frame bearing seat is connected with a frame mounting plate, and the frame mounting plate is connected to the vibration side support plate through a vibration side shock absorber.

[0012] Further, the auxiliary compaction wheel is connected to the frame mounting plate. An installation bracket and a rolling device are sequentially connected between the auxiliary compaction wheel and the frame mounting plate. The installation bracket is arranged in an L shape. Both ends of the installation bracket are respectively fixedly connected to the frame mounting plate and the rolling device. The auxiliary compaction wheel is rotatably connected to the rolling device.

[0013] Further, the rolling device includes a bearing seat, a bearing cover, a rolling bearing, a large nut, a mounting shaft, and a mounting plate. The mounting shaft and the mounting plate are welded and connected. A round hole is opened inside the mounting plate for the fixation and limitation of the mounting shaft. The mounting shaft is fixedly connected to the installation bracket. The inner ring of the rolling bearing is assembled on the mounting shaft, and the outer ring is assembled on the bearing seat and is pressed tightly by the bearing cover and the large nut. Relative rotation is realized between the bearing seat and the mounting shaft. The auxiliary compaction wheel is connected to the bearing seat.

[0014] Further, the auxiliary compaction wheel is a smooth wheel, a flat plate, or a convex block wheel.

[0015] A road roller having the above-mentioned vibrating wheel for edge compaction is mainly applicable to small-scale projects in narrow spaces such as urban streets, alleys, parking lots, and park landscape roads.

[0016] Beneficial effects:

[0017] 1. The present invention adopts an auxiliary compaction wheel that extends longer than the main compaction wheel in the width direction. That is, during the compaction process, the auxiliary compaction wheel can make up for the width of the support plate extending out, enabling complete edge compaction. Moreover, the vibration wheel follows the form of double-sided support plates, with strong stability.

[0018] 2. The auxiliary compaction wheel adopted in the present invention is connected to the frame bearing mounting plate and participates in vibration together with the vibration wheel, which is more conducive to compaction and easy to ensure the compaction degree.

[0019] 3. The auxiliary compaction wheel adopted in the present invention can be replaced with other compaction devices such as a flat plate or a bump wheel to achieve other compaction effects such as the compaction effect of a plate rammer and bump compaction.

[0020] 4. When the present invention is in a non-working state, devices such as an oil cylinder can be used to lift the auxiliary compaction wheel to achieve rapid transfer. Auxiliary compaction devices can also be added to both sides of the main compaction wheel, and edge compaction can be achieved whether moving forward or backward. Brief Description of the Drawings
