Abstract
The utility model discloses a pulling type operation self-traveling digger, which belongs to an engineering plant. The pulling type operation self-traveling digger comprises a vehicle frame, traveling wheels and a driving cab, wherein, the traveling wheels are arranged on the front and the rear of the bottom of the vehicle frame; the driving cab is arranged in the middle of the surface of the vehicle frame through a loading revolving platform; one side of the vehicle frame is hinged with a dragging frame through a pulling steering body, and the other side of the vehicle frame opposite to the dragging frame is hinged with a movable arm; the front end of the movable arm is hinged with a bucket rod; and the front end of the bucket rod is hinged with a bucket. Compared with the prior art, the pulling type operation self-traveling digger has the characteristics of reasonable design, low production cost, high flexibility, capability of being flexibly operated in a narrow environment, etc.
Description
Technical field
The utility model relates to a kind of engineering machinery, and specifically a kind of pull-type operation is from walking excavator.
Background technology
Excavator is the construction machinery that is used for excavating soil, be mainly used in the trench excavation in the road construction work, irrigation canals and ditches, canal and river training are excavated in excavation basis in the construction project in the hydraulic engineering, peel off with the excavation of ore in engineerings such as stope, strip mining transformation etc.It is with in the bucket tooth on the scraper bowl cutting soil and the bucket of packing into, fills the soil back and promotes scraper bowl and return back to and unload the soil point and unload soil, and then make turntable revolution, scraper bowl drop to excavation surface, excavates next time.In addition excavator after changing equipment, also can build, operations such as lifting, installation, piling, rammer soil and pile pulling.Excavator can be divided into two kinds of crawler type and rubber-tyreds by the difference of walking manner.With regard to common wheeled hydraulic excavator, complete machine is made up of equipment, revolving dial, dynamical system, hydraulic system, electrical system, running gear etc.Running gear by power train, turn to be, braking system, running gear etc. form.
In the digging operation, when working space is little, position, the excavator left and right sides only needs to adjust among a small circle in the course of work, the distance of at every turn advancing is also very short, excavating under the similar condition of parameter, running gear is operated in inefficient district more, is located at effective operation in the time, the ratio of excavator walking (turning to) time and working cycles (excavation, rotation, off-load, return) time is the relative utilization rate of excavator running gear, and then the average utilization rate relatively of its running gear obviously reduces.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides that a kind of cost of production is low, flexibility ratio is high, can be in a kind of pull-type operation of the narrow and small flexible operation of environment from walking excavator.
The technical scheme that its technical problem that solves the utility model adopts is: this excavator comprises vehicle frame, road wheel and driver's cabin, road wheel is arranged on the both sides, front and back of bottom of frame, driver's cabin is arranged on middle part, vehicle frame surface by the revolving dial of getting on the bus, one side of vehicle frame is by pulling round body and bracket is hinged, the opposite side and the swing arm of bracket are hinged relatively, the front end and the dipper of swing arm are hinged, and the front end and the scraper bowl of dipper are hinged.
Be connected with boom cylinder between described vehicle frame and the swing arm, be connected with bucket arm cylinder between swing arm and the dipper, be connected with bucket cylinder and connecting rod between dipper and the scraper bowl.
The vehicle frame on described driver's cabin next door is provided with hydraulic oil container and fuel tank, and the bottom of driver's cabin is provided with the tool box.
A kind of pull-type operation of the present utility model is compared with prior art from the excavator of walking, and has following characteristics:
(1) member such as newly-increased bracket can tow on highway easily, has saved the freight of crawler hypraulic excavator costliness and the expenses of taxation that hydraulic wheel excavator must be handed over, and has reduced the regular maintenance spending, meets user's requirement.
(2) cancelled traditional chassis of dredging machine, the restriction that do not have transmission, turn to, mechanisms such as speed change, differential connects, it is more reasonable, compact that complete machine is arranged, and the complete machine quality reduces, and the complete machine manufacturing cost reduces.
(3) each working solution cylinder pressure stroke pin joint position and boom structure help increasing the angle excursion between member when satisfying walking, and the pull-type operation can be worked in the narrow and small occasion that common excavator can't be worked freely from the excavator of walking.
(4) the road wheel grounding pressure is little, and the intensity height can adapt to mountain area and complicated earth surface operation.
(5) the pull-type operation is very convenient from the excavator migration of walking, and equipment and each hydraulic cylinder are used to be finished from walking, and the running gear cost reduces, and the complete machine cost performance obviously improves.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the structural representation of pull-type operation from the excavator of walking.
Accompanying drawing 2 is the plan structure schematic diagram of pull-type operation from the excavator of walking.
