Description

Use vibratory roller more

Technical field

The utility model belongs to the building machinery field, specifically a kind of vibratory rollers of using more.

Background technology

Existing road roller mostly is machinery or hydraulic drive, and its structure comprises frame, is contained in vibratory compaction wheel, power set on the frame, links to each other by transmission mechanism between vibratory compaction wheel and the power set.Owing to be subjected to the restriction of drive mechanism and drive path, existing road roller generally is only limited to the single horizontal compacting operation of the earthwork, is not easy to carry out compacting operation or operation quality is not high for the earthwork at corner, side slope place.The vibrator of particularly existing road roller is positioned at the shaft core position of compact wheel, and its exciting force is to pass to wheel rim and act on and be compacted material through wheel shaft, spoke.Equally, the self gravitation of road roller also is to pass to wheel rim and act on through wheel shaft, spoke to be compacted material.So compacting wheel shaft and bearing thereof will bear great load, thereby limited the raising of road roller exciting force and loaded weight.

Summary of the invention

Problem to be solved in the utility model provides a kind of vibratory roller of using that can improve exciting output and can implement to press operations such as corner, flanging slope, blading more.

The technical scheme that addresses the above problem is: what provided manyly comprises frame, is contained in vibratory compaction wheel, power set on the frame with vibratory roller, links to each other by transmission mechanism between vibratory compaction wheel and the power set.Improvements of the present utility model are that said power set are generating sets; The vibrator of said vibratory compaction wheel has a plurality of, and they are uniform to be installed on the inwall of compact wheel wheel rim; The wheel rim pivot of said compact wheel is lower than the loading blocks in wheel rim axle center by a center of gravity and the resiliency supported wheel of loading blocks is formed, and the inwall of compact wheel is provided with reinforcing ring, and aforementioned resiliency supported wheel places on the reinforcing ring of wheel rim; Said frame by longeron, be positioned at turning to vertical pivot and being hinged on the telescopic front fork that turns on the vertical pivot on the longeron and form, the operation annex is housed on the telescopic front fork; The loading blocks of aforementioned compact wheel is provided with a plurality of pin holes by circle distribution, and these a plurality of pin holes are corresponding with the fastening screw hole on the frame longeron respectively, and loading blocks is connected with the frame longeron by latch.The vibratory compaction wheel that the utility model adopts has changed vibration source installation site and power transmission route, and exciting force directly acts on without pivot on the wheel rim, therefore more bigger exciting sources can be installed, and improves exciting output.The utility model adopts driven by power, make and telescopic front fork is set becomes possibility, adjust the position of centre of gravity of road roller by the different operation annex of configuration on front fork with by the position of adjusting the compact wheel loading blocks again, thereby can implement to press several work such as corner, flanging slope, blading, illumination.

Compare with existing road roller, the utility model not only can be implemented several work, and owing to adopt driven by power and many exciting sources, not only make the compact overall structure of compacting machine, simplify drive path, and can adjust the exciting force output valve in the simplest mode of closing or several exciting sources, can also adjusting internal combustion engine rotating speed and then control supply frequency and excited frequency.In addition,,, increase substantially compaction capacity, lower the center of gravity, can not make the too much load of frame carrying simultaneously again so can increase the quality of compact wheel because compact wheel has adopted the form of structure of interior loading.

The specific embodiment

As shown in Figure 1: the frame of road roller comprises longeron 2 and telescopic front fork 6, be equipped with one in the left side of longeron 2 section and turn to vertical pivot 5, one end of telescopic front fork 6 is hinged on and turns on the vertical pivot 5, and other end installation exercise annex, the operation annex among the figure are the compact wheels 7 of minor diameter.Power set 3 and compact wheel 1 also are housed on the longeron 2, the power set 3 of this example are with the petrol-electric generating set group, and its electric power is exported to minor diameter compact wheel 7 and other driven by power parts on compact wheel motor 31, vibrator 4, operating room 8, illuminating lamp 9, the telescopic front fork 6.The vibrator 4 of compact wheel 1 has a plurality of, and they are distributed on the inwall of compact wheel wheel rim, and when each vibrator vibration, according to the barycenter conservation principle, each vibrator will produce synchronous vibration, thereby make the compact wheel vibration.In addition, on the inwall of compact wheel 1, also be provided with reinforcing ring 13; In reinforcing ring 13, be provided with the loading blocks 11 that a center of gravity is lower than the wheel rim axle center, this loading blocks lacks column for circle, and by 12 supports of resiliency supported wheel, and resiliency supported wheel 12 places on the reinforcing ring 13, so loading blocks 11 and support wheel 12 just are equivalent to the pivot of compact wheel.Motor 31 is installed in the upper surface of loading blocks 11, when motor 31 rotates, drive support wheel 12 by chain-drive mechanism and rotate, thereby the wheel rim that orders about compact wheel rotates, and promptly compact wheel 1 has from walking function.On the loading blocks 11 of compact wheel, also be provided with a plurality of pin holes 14 by circle distribution, these a plurality of pin holes 14 are corresponding with the fastening screw hole on the frame longeron 2 respectively, loading blocks 11 is connected with frame longeron 2 by latch, its effect is to regulate the position of loading blocks 11 with respect to compact wheel, thereby regulates the position of centre of gravity of whole road roller.As, loading blocks 11 is rotated counterclockwise an angle, with latch loading blocks 11 is connected the location with frame longeron 2 then, then move after the center of gravity.As previously mentioned, because the quality of compact wheel 1 is big, center of gravity is lower, changes so the variation of the position of centre of gravity of compact wheel 1 can obviously influence the position of centre of gravity of whole road roller, and this just provides assurance for operations such as this road roller enforcement flanging slopes.
