One, technical field
Patent of the present invention belongs to engineering machinery field, is the working a kind of novel large-tonnage pipe slinging machine of diameter long-distance transport pipes too.
Two, background technology
Along with the continuous growth of domestic energy demand, the China National Petroleum pipe-line construction also develops rapidly.Because operational throughput is big, pipe diameter is increasing.The pipeline of transferring natural gas from the west to the east diameter increases, next step transfering natural gas from the west to the east multiple line engineering and Russia gas east send the engineering pipeline diameter further to increase, according to construction process requirement, original pipe sling can not meet the demands, and the present situation of engineering construction presses for a kind of more large-tonnage pipe sling.
Three, summary of the invention
In order to overcome the limitation of existing pipe sling, the invention provides a kind of novel large-tonnage pipe slinging machine, this steering unit has big, the advantages such as intensity is high, good stability of lifting tonnage.
Solution of the present invention is as follows:
A kind of novel large-tonnage pipe slinging machine comprises swing type mechanism, lifting mechanism, truss arm, counterweight, telescopic oil cylinder, luffing mechanism, suspension hook, hydraulic efficiency gear, engine installation, operator's compartment, caterpillar chassis, safety device; The operating mechanism of hydraulic efficiency gear is arranged in the operator's compartment, and truss-like arm one end is articulated and connected by bearing pin and bench board, and lifting mechanism is arranged on suspension hook by its steel rope the other end of truss-like arm; Counterweight and telescopic oil cylinder are installed in the opposite side of bench board, and luffing mechanism, telescopic oil cylinder, lifting mechanism are connected with hydraulic efficiency gear, engine installation connects with hydraulic efficiency gear, and the gear of track sprocket adopts externally swing; Counterweight is located on the vehicle frame by four-bar linkage structure, and is in the offside of truss-like arm.
Above-mentioned a kind of novel large-tonnage pipe slinging machine, driving engine is positioned at the front side on chassis, and fuel tank is positioned at the rear side on chassis.
Above-mentioned a kind of novel large-tonnage pipe slinging machine, the truss-like arm is provided with shock absorber.
Above-mentioned a kind of novel large-tonnage pipe slinging machine, described externally swing drive wheel includes gear ring, spoke, wheel hub, and gear ring is fixed on the wheel hub by spoke, and spoke is outward-dipping.
Design by outer pendulum type drive wheel has increased the requirement that width of tracks etc. satisfies large-tonnage pipe slinging machine; The engine in situ reach moves behind the fuel tank, guarantees the space of operator's compartment; Counterweight adopts the four-bar linkage structure form, puts distance outward, alleviates the weight of self, has also reduced the weight of complete machine; The counterweight support adopts the detachable design, is convenient to the transportation and the transition of large-tonnage pipe slinging machine.
Four, description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a construction profile scheme drawing of the present invention;
Fig. 3 is an externally swing drive wheel structural representation.
Five, the specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the 1st, suspension hook, the 2nd, operator's compartment, the 3rd, caterpillar chassis, the 4th, truss-like arm, the 5th, track sprocket, the 51st, gear ring, the 52nd, spoke, the 53rd, wheel hub, the 6th, counterweight.
A kind of novel large-tonnage pipe slinging machine comprises swing type mechanism, lifting mechanism, truss-like arm 4, counterweight, telescopic oil cylinder, luffing mechanism, suspension hook 1, hydraulic efficiency gear, engine installation, operator's compartment 2, caterpillar chassis 3, safety device; The operating mechanism of hydraulic efficiency gear is arranged in the operator's compartment 2, and truss-like arm 4 one ends are articulated and connected by bearing pin and bench board, and lifting mechanism is arranged on suspension hook by its steel rope the other end of truss-like arm 4; Counterweight, telescopic oil cylinder are installed in the opposite side of bench board, and luffing mechanism, telescopic oil cylinder, lifting mechanism are connected with hydraulic efficiency gear, engine installation connects with hydraulic efficiency gear, and the gear of track sprocket 5 adopts externally swing; Counterweight 6 is located on the vehicle frame by four-bar linkage structure, and is in the offside of truss-like arm 4.
Described a kind of novel large-tonnage pipe slinging machine, driving engine is positioned at the front side of caterpillar chassis 3, and fuel tank is positioned at the rear side of caterpillar chassis 3.Truss-like arm 4 is provided with shock absorber.
Described externally swing drive wheel 5 includes gear ring 51, spoke 52, wheel hub 53, and gear ring 51 is fixed on the wheel hub 53 by spoke 52, and spoke 52 is outward-dipping, and design by outer pendulum type drive wheel has increased the requirement that width of tracks etc. satisfies large-tonnage pipe slinging machine.The support of counterweight 6 is adopted as detachable.
Arm is selected the manufacturing of low carbon high-strength degree alloy steel for use, and the arm form adopts two C fonts to add the mode of reinforced rib, improves intensity and stability in expendable weight.
Hydraulic efficiency pressure system is selected load feedback multichannel pilot operated valve device for use, adopts guide's control, can realize the compound of suspension hook and arm action; Hydraulic wireline winch adopts two-in-one structure design, and lifting mechanism and luffing mechanism are arranged on one side of machine, have improved balancing torque, installs simple and convenient, rationally distributed.
On the car safety device mainly be highly spacing, arm is spacing and moment is spacing, improves reliability.When arm was about to put minimum radius, arm can be run into shock absorber earlier, if continue to receive arm, then inhibiting device begins to work, and cuts off arm motion, guaranteed that arm is not by stretch bending.
