Abstract
The utility model is a chassis moving system of caterpillar rotary hydraulic digger, mainly consisting of a caterpillar assembly, a guiding wheel and a tensioning device, a steel tube frame assembly of rectangular section, a footplate assembly, a return wheel assembly, a bearing wheel trolley assembly which can imitate terrain, and a driving device. The bearing wheel trolley assembly adopts a rigid and hanging structure, and the adjustment of the guiding wheel and the tension force in the tensioning device adopts the lead screw structure of M48* 2, and the frame assembly adopts steel tube with rectangular section, height of 250 plus or minus 10 mm, width of 100 plus or minus 10 mm and thickness of 10 plus or minus 1 mm and is jointed into ''H'' structure. The utility model has simple structure and low cost, and is mainly used for the caterpillar rotary hydraulic digger.
Description
(1) technical field:
The utility model belongs to the excavating machine field, relates to a kind of crawler type full circle swinging hydraulic excavator chassis running gear.
(2) background technology:
At present, crawler type full circle swinging hydraulic excavator chassis running gear commonly used adopts usually installs the rigidity caterpillar wheel on rigid-frame, and adopts high rail crawler belt.During walking, crawler belt and caterpillar wheel are difficult to adjust self-position according to change of topography, cause jerk easily.Therefore must prevent the damage that causes because of impact with the way that adds plate iron when designing.In addition, actuating device adopts the multirow star row mechanism retarder of high-speed hydraulic motor and big speed ratio, and cost is higher, price Jiao Expensive.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, imitative landform in-use performance good, high efficiency, lower-cost crawler type full circle swinging hydraulic excavator chassis running gear.
The utility model can be achieved through the following technical solutions: crawler type full circle swinging hydraulic excavator chassis running gear, mainly contain track rail assembly 1, track adjusting wheel and tightening device assembly 2, square-section steel pipe frame assembly 3, pedal assembly 4, carrier wheel assembly 5 can be imitated the caterpillar wheel trolley assembly 6 of landform, actuating device 7 compositions such as grade.
In the utility model, track adjusting wheel and tightening device assembly 2, pedal assembly 4, carrier wheel assembly 5, can imitate the caterpillar wheel trolley assembly 6 of landform, actuating device 7, left-right symmetric is installed in the both sides of square-section steel pipe vehicle frame 3 respectively, and track rail assembly 1 left-right symmetric is around being enclosed within track adjusting wheel and tightening device assembly 2, carrier wheel assembly 5, can imitate the caterpillar wheel trolley assembly 6 of landform, actuating device 7 outsides constitute the whole chassis running gear.
Tensioning adjusting mechanism in track adjusting wheel and the tightening device assembly 2 adopts the leading screw of M48 * 2, adjusts track adjusting wheel and moves forward and backward securable crawler belt; Actuating device 7 adopts low speed high torque hydraulic motor, is 6.09 one-level straight-tooth transmission speed reducer drive drive wheel rotation by transmitting ratio; Frame assembly 3 adopts high 250 ± 10mm, and wide 100 ± 10mm, the square-section steel pipe of thick 10 ± 1mm are welded into " H " type structure; Caterpillar wheel trolley assembly 6 adopts rigid suspended structure and can imitate the landform walking.This utility model track center distance is that 1850 ± 5mm, wheelbase are that 2635 ± 5mm, road clearance are that 350mm, ground contact length are that 2500mm, crawler width are that 400 ± 5mm, preceding caterpillar wheel and track adjusting wheel outer rim tangent line and the formed angle of attach of horizontal surface are that 3 °～4 °, back caterpillar wheel and drive wheel outer rim tangent line and the formed departure angle of horizontal surface are 3 °～4 °.
The utility model can reach following good effect: because the leading screw adjustment of tightening device 2 usefulness M48 * 2, make tensile force big, frame assembly 3 adopts the square-section of high 250 ± 10mm, wide 100 ± 10mm, thick 10 ± 1mm to be welded into " H " type structure, load-carrying capacity height.Reductor in the actuating device 7 adopts the transmission of one-level straight-tooth, and simple in structure, cost is low.When caterpillar wheel trolley assembly 6 is walked at excavating machine, can imitate the landform motion, reduce impact.Thereby further improved the in-use performance of chassis of dredging machine running gear.
(4) description of drawings:
Fig. 1 is the main TV structure figure of the utility model crawler type full circle swinging hydraulic excavator chassis running gear.
Fig. 2 is the plan structure figure of the utility model crawler type full circle swinging hydraulic excavator chassis running gear.
(5) specific embodiment:
With track adjusting wheel and tightening device assembly 2, carrier wheel assembly 5, can imitate the caterpillar wheel trolley assembly 6 of landform, actuating device 7, left-right symmetric is installed in the both sides of square-section steel pipe frame assembly 3 respectively, and track rail assembly 1 left-right symmetric is around being enclosed within track adjusting wheel and tightening device assembly 2, carrier wheel assembly 5, can imitate the caterpillar wheel trolley assembly 6 of landform, actuating device 7 outsides constitute the whole chassis running gear.
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 low-speed big torque motor in the actuating device 7, make the motor left rotation and right rotation, by making the drive wheel rotation after slowing down, the motion of drive track rail assembly, thus travel before and after making excavating machine.
