Description
Technical field
The utility model relates to a kind of improved hydraulic crawler excavator, particularly a kind of can be in marsh with a varied topography, wetland carries out operation and when removing middle-size and small-size building construction, the novel walking Double-arm hydraulic excavator that can effectively increase work efficiency.
Background technology
Hydraulic crawler excavator is used widely in places such as communications and transportation, civilian construction, mining and municipal engineering, is a kind of important engineering machinery conventional in various earth and rock workses.According to walking manner, hydraulic crawler excavator can be divided into wheel excavator, crawler-mounted excavator and walking type excavator.Wheel excavator running gear adopts rubber-tyred to carry out operation, and little with contact area of ground, grounding pressure is large, therefore in marsh, tire incision depth of soil is darker during wetland operation, is unfavorable for walking; Crawler-mounted excavator because of running gear contact area large, so be adapted at the building sites such as marsh, wetland, carry out operation, but due to the restriction of crawler-mounted excavator structure, can not be on the complex-terrains such as rugged song, precipitous or tall and big obstruction the operation of safe and effective rate, can only be by manually carrying out operation; Existing walking type excavator running gear utilizes independent multiple-degree-of-freedom steering hydraulic supporting leg to carry out free angle adjustment, and compensation landform convex-concave difference in height, realizes and travelling in wide-angle tilt landform, walking, the object of construction; Although running gear, when motion, can carry out multiple degrees of freedom adjusting, adjustable range is not very large; What simultaneously running gear adopted is that end face appearance profile is the caterpillar wheel of circle, and it is little with ground contact surface, so is also not suitable in occasion operations such as marsh, wetlands.
In addition, generally the hydraulic crawler excavator of application is all single arm type now, relatively simple for structure, easy to operate.But when removing middle-size and small-size building construction, need to first utilize hydraulic breaking hammer to carry out fragmentation, and then with scraper bowl, broken thing be loaded and transported.Because hydraulic crawler excavator adopts single armed, therefore when operation, need to change back and forth quartering hammer and scraper bowl, not only operator is arduous, and inefficiency, loses time.
Utility model content
The purpose of this utility model is to provide a kind of novel walking Double-arm hydraulic excavator.
The technical solution of the utility model: a kind of novel walking Double-arm hydraulic excavator, comprise running gear, digger arm, described running gear comprises supporting leg, and the upper end of supporting leg and one end of upper rotating disc are hinged, and the other end of upper rotating disc is connected with chassis and dial rotation pair; The lower end of supporting leg and one end of lower rotating disc are hinged, and the other end of lower rotating disc is connected with steering wheel and rotation pin revolute pair, and steering wheel is arranged on walking wheel by bearing; Between a side of supporting leg and rotation pin, be provided with right hydraulic jack, between the opposite side of supporting leg and rotating disk, be provided with left hydraulic jack.
Described walking wheel is walking three horn rings.
Described digger arm is both arms, comprises dipper-arm, broken hammerhead jib, and their bottom is hinged on respectively on the revolving bed of excavator.
The utility model is changed into double-arm by single arm type, saved the trouble of changing back and forth quartering hammer and scraper bowl, has alleviated workman's labour intensity, and operating efficiency significantly improves; The design of running gear is more reasonable, regulates degree of freedom and adjustable range to improve a lot, and can compensate landform convex-concave difference in height, can travel in wide-angle tilt landform; The use of walking three horn rings, has increased the contact area with ground, more can allow the poor place of its condition of compatibility, especially muddy road and swamp land.
Accompanying drawing explanation
Fig. 1 is the structural representation (single walking three horn rings) of the utility model running gear.
Fig. 2 is the structural representation (end face) of walking three horn rings in the utility model running gear.
Fig. 3 is the structural representation of the utility model dipper-arm, broken hammerhead jib and car body.
Fig. 4 is structural representation of the present utility model.
In figure: 1 chassis, rotating disc on 2,3 supporting legs, 4 right hydraulic jacks, 5 rotation pins, 6 walking three horn rings, 7 rotating disks, 8 left hydraulic jacks, 9 lower rotating discs, 10 steering wheels, 11 dipper-arms, 12 broken hammerhead jibs, 13 downward moving arm oil cylinders, boom cylinder on 14,16 revolving beds, 17 driver's cabins, 18 car bodies, 21 running gears.
The specific embodiment
Improvement of the present utility model is mainly changing the single armed of excavator into both arms (dipper-arm, broken hammerhead jib), and the design of running gear is more reasonable.
Therefore as shown in Figure 1, between the upper rotating disc 2 of the utility model running gear, chassis 1 and rotating disk 7, adopt the connected mode of revolute pair, can control the rotate central axis of dish 7 of rotating disc 2 and be rotated.Between lower rotating disc 9 and steering wheel 10, rotation pin 5, also adopt the connected mode of revolute pair, lower rotating disc 9 can be around 5 rotations of rotation pin.When controlling rotating disc 2 and rotate, by the connection of supporting leg 3, walking three horn rings 6 just can be on horizontal plane around the revolute pair axis rotation between chassis 1 and upper rotating disc 2, rotating disk 7; Meanwhile, walking three horn rings 6 also can be realized and rotating around rotation pin 5.Right hydraulic jack 4 upper ends are hinged on supporting leg 3, and lower end is hinged on rotation pin 5, and flexible walking three horn rings 6 of can controlling of right hydraulic jack 4 are around supporting leg 3 and lower rotating disc 9 hinged place rotations.Left hydraulic jack 8 lower ends are hinged on supporting leg 3, upper end is hinged on rotating disk 7, therefore, the flexible supporting leg 3 of can controlling of left hydraulic jack 8 is rotated around supporting leg 3 and upper rotating disc 2 hinged places, and then has also just controlled walking three horn rings 6 in the movement vertically and in horizontal direction; Adopt bearing to be connected with steering wheel 10 walking three horn rings 6, walking three horn rings 6 can be rotated around steering wheel 10.Several motions are in conjunction with just realizing the multiple degrees of freedom of walking three horn rings, the adjustment of multi-angle above.
As shown in Figure 3, revolving bed 16 of the present utility model and car body 18 adopt the connected mode of revolute pairs, the bottom of dipper-arm 11 and broken hammerhead jib 12 is hinged on respectively on revolving bed 16, and when controlling revolving bed 16 spinning movement, dipper-arm 11 and broken hammerhead jib 12 can rotate by wraparound transposase 11 6; One end of downward moving arm oil cylinder 13 and upper boom cylinder 14 is hinged on revolving bed 16 by connecting pin, the other end and dipper-arm 11 or broken hammerhead jib 12 carry out hinged, by stretching of HYDRAULIC CONTROL SYSTEM downward moving arm oil cylinder 13 and upper boom cylinder 14, can make dipper-arm 11 and broken hammerhead jib 12 carry out work.
Driver's cabin 17 of the present utility model is arranged with oil cylinder, can adjust as required the height of driver's cabin 17.
It is same as the prior art that this manual is not described in detail.
