Description

Road and bridge overall width paver

The utility model belongs to a new machine of road building machinery middle orbit formula cement concrete spreader.

At present, the high-grade highway of China, especially cement concrete pavement is built in a large number.Manually-operated construction in the past is not competent.The little facility of vacuum dehydration do not adapt to the desired high-speed and high-quality of the development situation of advancing by leaps and bounds yet.Big machinery construction an urgent demand has superior performance, adaptable cement concrete spreader.Several years ago, China has bought a collection of paver from the West Germany and the U.S., and price is very expensive, and is relatively poor to the half-dried rigid concrete compliance that adopt on China Higher level road surface.So, digest, absorb and the problem of developing homemade large-scale cement concrete spreader has been listed Ministry of Communications's Seventh Five-Year Plan in.Many R﹠D institutions and producer are devoted to this work one after another.

Such a word is arranged: " large-scale rail mounted paver still belongs to the starting stage at home " in one piece of paper.(see Appendix 2: " highway " magazine the 2nd phase of nineteen ninety Wang Ya of Highway Planning and Designing Inst., Ministry of Communications does the article " brief talking highway in China construction of cement concrete road surface mechanical problem " that waits).This article has been enumerated the important technological parameters (seeing table 2 in the literary composition) of four kinds of homemade pavers.Wherein " the cement concrete cloth plain bumper and the walking track thereof " of " the rail mounted cement concrete refiner " of Pingshan Machinary Repairing Factory, Jiangsu Traffic Engineering Co. and Nanjing Construction Machinery Plant finds (number of patent application is respectively 88219333.3 and 89205209.0) in the Searches of Patent Literature.

The import paver is whole-colored all-hydraulic transmission, and homemade majority is to copy.The refiner in mechanical repair plant, the Pingshan Mountain adopts electronic, and through contrast, the all-electric compound mode of this machine and it are completely different.The paving width of these pavers generally has only 4.5 meters, and direction is by the way adopted in jolt ramming.Maximum West Germany Fu Gele 9-65 type machine also can only spread out 9 meters.And the Class II highway fabric width has reached 15 meters, thereby can not disposable full section making, can only divide and make a few width of cloth makings.Disease appears in constuction joint easily, influences road quality and life-span.And can only beat the road surface, be difficult to be applicable to dozen bridge floor.Can piece together very longly though Nanjing Construction Machinery Plant introduces the C-450 frame of American technology production, this machine structure is also completely different with it.

The development the purpose of this utility model is just in order to obtain to be suitable for paver national conditions, that performance is more superior.

This machine structure sees that accompanying drawing just comes into plain view.Frame 3 three parts of wiping one's face by Slicking apparatus 1 in front, middle shake flat-bed machine 2 and back constitute unit.

Slicking apparatus 1 selects for use volume little and the two-stage vertical cycloidal-pin wheel reducing motor 14 big, through turning from side to side of exerting oneself directly drives 17,360 ° of two-way rotations of especially big rotor segment of 2 meters long.Longitudinal and transverse moving all adopted horizontal cycloidal-pin wheel reducing motor 10,39, by chain 9 and wire rope 13 transmissions.Both sides road wheel 21 can transfer, to adapt to bend and to overcome derailing.If alarm bell and illuminating lamp 15 are guaranteed safety and are carried on construction work at night.

Electrical control cubicles 26 is installed in the sunshade 27 on the traversing framework 24, and operator's side direction is sitting on the comfortable couch 25, and people and cabinet are with together displacement of scraper plate 17.Skillfully move back and forth three small and exquisite master switches 37, come the making up at random of layout all around, three kinds of motions of rotating, rely on the powerful power that pushes, concrete is arranged into the position of any needs like the hillock that the large-tonnage automobile is toppled over rapidly.The cloth charge level is smooth, the bulk density unanimity.

The frame of flat-bed machine 2 of shaking is identical with Slicking apparatus 1.Drive eccentric shafts 32 high speeds and rotate starting of oscillation with spring 36 long 33, two heavy-duty motors of vibration ship 31 of 4-5 rice that suspending on the compact traversing framework 30.Vibration ship 33 is by the way to storing.Laterally drag and shake.The jolt ramming of first road, 2 clap for one, overlap 0.5 meter at every turn.Jolt ramming effect and planeness are all better.

The utility model compared with prior art, advantage is a lot of.Adopt all-electric, component all to select for use homemade high-quality general part, operation and maintenance very convenient, the shortcoming of avoided hydraulic part fault rate height, cost an arm and a leg, limit conversion, the accessory difficulty being looked for.

Electric control operation mechanism is small and exquisite flexibly, pulls one hair and move the whole body.Plate pull bar, pedal unlike the import machine, and the operator tightly waiting Hong toot motor, standing huge noise.It need only connect root cable 28 and get final product away from motor.Not only meet civilized construction, concerning the operator, liberation only not.

Laterally dragging of it shaken, and makes any road making be achieved, and made things convenient for the adjustment of road camber degree, lays a good foundation for road and bridge are dual-purpose.

Now accompanying drawing is made explanation more carefully.
