Description
(1) technical field:
The utility model belongs to the excavating machine field, relates to a kind of replaceable crawler type full circle swinging chassis of dredging machine running gear.
(2) background technology:
At present, China's crawler type full circle swinging chassis of dredging machine running gear commonly used adopts usually installs rigidity coventional type caterpillar wheel on rigid-frame, and adopts high rail steel system crawler belt, and this device quality is heavy, the cost height, and price is expensive; Do not changing under the running gear structure situation in addition, the steel crawler belt can not directly be replaced mutually with using increasing rubber belt track.
(3) summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, in-use performance good, high efficiency, cost is lower, do not changing under the running gear structure situation crawler type full circle swinging chassis of dredging machine running gear that steel crawler belt and rubber belt track can be replaced mutually.So-called replaceable type does not promptly need to change the direct replacement that the relevant parts of running gear can be realized steel crawler belt and rubber belt track, has improved through performance.Caterpillar wheel is designed to replaceable type, no matter adorns steel crawler belt or rubber belt track, all can prevent the crawler belt derailing.
The utility model can be achieved through the following technical solutions above-mentioned purpose: crawler type full circle swinging chassis of dredging machine running gear comprises track rail assembly 1, track adjusting wheel and tightening device assembly 2, frame assembly 3, adopt steel plate bending welding, shape is welded into " X " shape structure, carrier wheel assembly 4
The replaceable type caterpillar wheel of 250mm assembly 5, pedal assembly 6, actuating device 7.It is characterized in that: frame assembly 3 both sides are symmetrically welded with longeron 8; Track adjusting wheel and tightening device assembly 2 adopt oil cylinder tensioner and spring buffer structure, and symmetry is installed in longeron 8 front ends of vehicle frame respectively; Replaceability caterpillar wheel 5 is cemented in chassis side rail 8 bottoms by the bolt symmetry; Carrier wheel assembly 4 symmetries are fixed on chassis side rail 8 tops; Driving unit assembly 7 by bolt respectively symmetry be fixed in longeron 8 rear ends; Track rail assembly 1 left-right symmetric is around being enclosed within on track adjusting wheel and tightening device assembly 2,2 the carrier wheel assemblies 4 in every limit, 5 the replaceable type caterpillar wheel assemblies 5 in every limit and the driving unit assembly 7.Move toward the interior grease promotion piston that injects of tensioner oil cylinder,, constitute the whole chassis running gear the crawler belt tensioner.
This device gauge is 1900 ± 10mm, during dress steel crawler belt wheelbase be 2634 ± 10mm,, crawler width is 440 ± 5mm, road clearance is 399mm ± 5mm; Dress rubber belt track wheelbase is 2660 ± 10mm, and crawler width is 400 ± 5mm, and road clearance is 448mm ± 5mm; Preceding caterpillar wheel and track adjusting wheel outer rim tangent line and the formed angle of attach of horizontal surface are 2 °～3 °, and back caterpillar wheel and drive wheel outer rim tangent line and the formed departure angle of horizontal surface are 2 °～3 °, have increased ground contact length, have reduced grounding pressure.
The utility model can reach following good effect: do not have the use of carrying out the board-like steel track rail assembly 1 of thorn and can reduce steering resisting torque, energy savings does not have board-like steel crawler belt of the thorn of carrying out and integral rubber crawler belt and can directly replace as required, can travel at urban pavement.Oil cylinder tensioner and spring buffer structure are adopted in tensile force adjustment in track adjusting wheel and the tightening device assembly 2, move toward the interior grease promotion piston that injects of tensioner oil cylinder, the crawler belt tensioner, track adjusting wheel runs into obstacle or resistance spring plays buffer action during walking, improved tensile force, improve buffer action, reduced impulsive force; Replaceable type caterpillar wheel assembly 5 can prevent crawler belt derailing, and this chassis intensity height, cost are low.
(4) description of drawings:
Fig. 1 is the main TV structure figure of the replaceable crawler type full circle swinging of the utility model chassis of dredging machine running gear.
Fig. 2 is the plan structure figure of the replaceable crawler type full circle swinging of the utility model chassis of dredging machine running gear.
(5) specific embodiment:
As shown in Figure 1 and Figure 2, frame assembly 3 adopts steel plate bending welding, and shape is welded into " X " shape structure, and both sides are symmetrically welded with longeron 8; Track adjusting wheel and tightening device assembly 2 adopt oil cylinder tensioner and spring buffer structure, and symmetry is installed in longeron 8 front ends of vehicle frame respectively; Replaceability caterpillar wheel 5 is cemented in chassis side rail 8 bottoms by the bolt symmetry; Carrier wheel assembly 4 symmetries are fixed on chassis side rail 8 tops; Driving unit assembly 7 by bolt respectively symmetry be fixed in longeron 8 rear ends; Track rail assembly 1 left-right symmetric is around being enclosed within on track adjusting wheel and tightening device assembly 2,2 the carrier wheel assemblies 4 in every limit, 5 the replaceable type caterpillar wheel assemblies 5 in every limit and the driving unit assembly 7.Move toward the interior grease promotion piston that injects of tensioner oil cylinder,, constitute the whole chassis running gear the crawler belt tensioner.
During excavating machine work, driving engine drives the oil pump rotation, the output high pressure oil, by oil pipe high pressure oil is flowed to hydraulic drive motor in the actuating device 7, make the motor rotation, drive track rail assembly 1 motion by bonded assembly drive wheel on the retarder, thereby travel before and after making excavating machine.The utility model can be used for 10～12 tons of excavating machines, has improved the in-use performance of chassis of dredging machine running gear, has reduced manufacturing cost.
