As shown in Fig. 2 A to 2B, during crawler belt type dynamic compaction machine work, especially soft foundation during ground, after detacher breaks off relations, complete machine moves behind center, drives rocking of complete machine.Arrange by structure space and affect, counterweight is generally arranged in most afterbody, by the weight of reasonable Arrangement structural member, counterweight is reasonably distributed, and effectively reduces the rocking property of complete machine.
The counterweight of crawler belt type dynamic compaction machine of the present invention is arranged according to before and after certain ratio, and the left counterweight in front end and the vehicle frame left side adopt bearing pin to be fixedly connected with, and counterweight center of gravity (namely counterweight is arranged symmetrically with on track centerline) on track center.The right counterweight in front end is fixedly connected with adopting bearing pin on the right of vehicle frame, and counterweight center of gravity (namely counterweight is arranged symmetrically with on track centerline) on track center.Rear portion counterweight adopts bearing pin to be fixedly connected with vehicle frame afterbody.
The long track beam (longer than existing structure), broad track plate, the low grounding pressure etc. that improve crawler belt type dynamic compaction machine of the present invention can improve stability.
Large row energy dynamic compaction is applicable to process the grounds such as gravelly soil, sand, the silt of unsaturation or low saturation and cohesive soil, collapsible loess, miscellaneous fill and plain fill.The simple two class one that are divided into by ground are that to ram rear hole be non-collapsed ground (as rubble, pan soil), and another kind of is ram rear hole to subside ground (sandy soil).
As shown in Figure 2 A, be reverse construction during crawler belt type dynamic compaction machine construction, the circle being D as diameter in Fig. 2 A is called accessible working region (i.e. possibility territory, subsidence area).
As shown in Figure 2 B, L4 be complete machine center to track beam centre distance, L3 be amplitude and hammer ram center of gravity to track beam centre distance, L is the distance of equalising torque point to track center.
Learn according to equalising torque theory: it is equal that hammer ram generation moment and complete machine center produce moment: hammer ram weight G0*(L4+L)=complete machine weight G1*(L3-L).
L size has influence on a size for whole vehicle stability and car load rolling point amount.Know under the condition not changing complete machine weight and L size by relational expression, improve and ram and (hammer ram weight can be increased), the value of L3 can only be reduced.
When crawler belt type dynamic compaction machine of the present invention adopts 4 wheel driven walking and the dividing of directionless front and back difference.As illustrated in figs. 2 c and 2d, dynamic compaction machinery track beam front end extension elongation L1(fixing before hinge to track beam front end distance) after <1 track beam the fixing hinge afterwards of overhang L2(to track beam rear end distance).
According to the different scenes of construction, by track beam exchange assembling, crawler belt type dynamic compaction machine hammer ram setting point can be made to drop between two crawler belts, increase hammer ram weight, ensure that whole vehicle stability and less rocking property, low cost realizes large rammer and can promote.
According to one embodiment of present invention, dynamic compaction machinery adopts 4 wheel driven walking, and left and right crawler belt can exchange use, realizes subsiding foundation construction and non-collapsed foundation construction two kinds of duties by the exchange of left and right crawler belt.
Under the state of foundation construction of subsiding, make the front pin joint of jib and vehicle frame platform to the distance of left and right crawler belt front end, be less than the distance of rear pin joint to left and right crawler belt rear end of jib and vehicle frame platform, and between the front portion making the setting point of hammer ram drop on left crawler belt and the front portion of right-hand track chiain; Under the state of non-collapsed foundation construction, the front pin joint of jib and vehicle frame platform is greater than jib and vehicle frame platform rear pin joint to the distance of left and right crawler belt front end to left and right crawler belt rear end distance and between the front portion making the setting point of hammer ram drop on left crawler belt and the front portion of right-hand track chiain.
Crawler belt type dynamic compaction machine of the present invention is a kind of crawler type strong rammer compactor for special uprpose, solves the problem that existing crawler type strong rammer hits poor stability, can realize the walking of band hammer, raise the efficiency advantage, reliability, stability and safety during guarantee dynamic compaction machinery operation.After effectively reducing Condition of Sudden Unloading, jib bounce-back vibration and dynamic compaction machinery car load rock simultaneously.The present invention has reasonable in design, convenient transportation,
Simple to operate, transmission efficiency is stablized.
