Abstract
Double-amplitude building tamper includes driver unit, handle adjusting rod, main tamping body and vibrator, and features the vibrator inside the main tamping body and double-shaft structure with two eccentric blocks. Two eccentric blocks are installed in the middle part of two long shaft separately, and the two long shafts of vibrator are installed via bearings and pedestals onto right and left ribbed boards of the main tamping body. During working, the two eccentric blocks of different weight rotate oppositely to produce two different amplitudes. The moving direction of the tamper is changed by switching between the front and the back clutches with the adjusting rod to change the phase difference between two eccentric blocks. The building tamper is suitable for densifying dam, road bed and road surface.
Description
The present invention relates to a kind of building foundation compacting engineering machinery, particularly adopt the double-amplitude method to tamp the ballast consolidating machine on all kinds of soil, sandstone, dykes and dams, roadbed or road surface.
The at present domestic machinery that is used to build compacting mainly is vibratory plate compactor, Chinese patent 95109054.5 jolt oscillating rammer for building for example, it is made up of power set, power set base, guardrail, handrail, intermediate transmission mechanism, connecting axle, spring, adjusting hand lever, main rammer body and vibrator, power set by bolton on the power set base, the power set base is fixed on the main rammer body by spring, and the belt pulley of power set output links to each other by the belt pulley of belt with the main rammer body vibrator.Vibrator is installed on the main rammer body, vibrator is made of eccentric block, bearing, gear and belt pulley, they are installed on one, belt pulley is contained in a side of axle, eccentric block is at the middle part of axle, its shortcoming is that eccentric block centers on the rotation of axle, the transmission process more complicated, and can not satisfy the needs of double-amplitude compacting.
The purpose of this invention is to provide a kind of two kinds of various amplitudes that have, the double-amplitude building tamper of the positive and negative both direction walking of energy.
The present invention realizes like this, this double-amplitude building tamper is to improve on the basis of original jolt oscillating rammer for building, vibrator in main rammer body adopts the two eccentric block structures of twin shaft, be that vibrator is made up of two parallel major axis and two eccentric blocks, two eccentric blocks are contained in the middle part of two major axis respectively, and two major axis of vibrator are installed on the left and right gusset of main rammer body by bearing and bearing support.Homonymy one end at two major axis respectively is equipped with gear, and two gears intermesh.During work, two different eccentric blocks of quality rotate relatively, can produce two kinds of different amplitudes.Switch the direction of advance that the front and back friction clutch changes eccentric block phasic difference can change building tamper with regulating hand lever.
The present invention is further described below in conjunction with drawings and Examples.

Fig. 6, the eccentric block rotation schematic diagram of walking in the other direction.
Referring to Fig. 1～Fig. 4, a kind of double-amplitude building tamper, comprise power set 1, power set panel seat 2, guardrail 3, handrail 4, middle axle sleeve 5, connecting axle 6, extension spring 7, regulate hand lever 8, main rammer body 9 and vibrator 10, power set 1 by bolton on power set panel seat 2, power set panel seat 2 front ends link to each other with guardrail 3 by extension spring 7, power set panel seat 2 rear ends are supported and fixed on the main rammer body 9 by middle axle sleeve 5 and connecting axle 6, and the belt pulley 11 of power set output links to each other by the belt pulley 13 of the vibrator 10 in belt 12 and the main rammer body 9; A handrail 4 is equipped with in guardrail 3 rear ends, it is characterized in that vibrator 10 in main rammer body 9 is by two parallel major axis 15,16, two eccentric blocks 17 are formed, two eccentric blocks 17 are contained in two major axis, 15,16 middle parts respectively, and major axis 15,16 is installed on the left and right gusset 20 of main rammer body through bearing 18 and bearing support 19; End on major axis 15 is equipped with inner cone bearing support 28, compression spring 21, friction clutch compressing tablet 22 and friction clutch 23 are equipped with in inner cone bearing support 28 outsides, external toothing 24, bearing 18 and bearing support 19 are equipped with in inner cone bearing support 28 inboards, the other end of major axis 15 is equipped with bearing support 19, bearing 18 and gear 25, gear 25 inboards are provided with sector grooves 26, and a cam ring 27 is housed in sector grooves 26; End on major axis 16 is equipped with belt pulley 13, compression spring 21, friction clutch compressing tablet 22 and friction clutch 23 are equipped with in belt pulley 13 outsides, external toothing 24, bearing support 19 and bearing 18 are equipped with in belt pulley 13 inboards, the other end of major axis 16 is equipped with bearing 18, bearing support 19 and gear 29, and gear 29 and gear 25 intermesh; Regulate hand lever 8 and be fixed on the main rammer body 9 by axle 30 and axle sleeve 31, push-and-pull pressing plate 14 is equipped with in the lower end of regulating hand lever 8, and adjusting hand lever 8 can drive push-and-pull pressing plate 14 and move forward and backward; Guardrail 3 warp beam sleeves 32 and bolt 33 link together with main rammer body 9.
Another characteristics of this double-amplitude building tamper are that the eccentric block 19 in the vibrator 10 is eccentric blocks of quality inequality, also can be the eccentric blocks of equal in quality.When two eccentric block qualities not simultaneously, relatively rotation can produce two kinds of different amplitudes.
This double-amplitude building tamper work engineering is as follows:
Referring to Fig. 2 and Fig. 4～Fig. 6, the power set belt pulley drives the belt pulley rotation of vibrator by belt, when the adjusting hand lever pushes away forward, it drives the push-and-pull pressing plate and moves backward, in the awl groove that the push-and-pull pressing plate is pressed into the inner cone bearing support with the Bearing housing and the friction clutch compressing tablet of vibrator back simultaneously by the inclined-plane, the groove inner spring is compacted, back friction clutch works, the compression spring of front is in release conditions, and preceding friction clutch is just inoperative, at this moment, the gear ring of inner cone bearing support inboard drives major axis and rotates, the eccentric block that is the back rotates, and the cam ring of the major axis other end and gear be rotation thereupon also, and the gear that this gear drives on the major axis of back again rotates, promptly, latter two eccentric block relatively rotates, and the position is mutually identical, and at this moment, building tamper is walking forward just.When the adjusting hand lever pulls back, it drives the push-and-pull pressing plate and moves forward, in the awl groove that the push-and-pull pressing plate is pressed into belt pulley with the Bearing housing and the friction clutch compressing tablet of vibrator back simultaneously by the inclined-plane, awl groove inner spring is compacted, preceding friction clutch works, the compression spring of back is in release conditions, back friction clutch is just inoperative, and at this moment, the gear ring of belt pulley inboard drives major axis and rotates, the eccentric block that is the front rotates, the gear of the major axis other end is rotation thereupon also, and this gear promotes to have the gear rotation of sector grooves, has after 180 ° of angles of gear idle running of sector grooves, the rotation of drive cam ring, cam ring drives major axis and the back eccentric block rotates, and at this moment, pre-eccentric piece and back eccentric block relatively rotate, and the position differs 180 ° of angles, and building tamper is walking backward just.Realize that this building tamper moves forwards or backwards.When the adjusting hand lever mediated state, forward and backward compression spring all was in release conditions, and belt pulley is bringing onto load not, was convenient to power set and started.
Building tamper of the present invention is simple in structure, symmetrical, volume is little, makes easily, and is simple to operate.Be applicable to all kinds of soil of compacting, sandstone, dykes and dams, roadbed or road surface.
