Description

A kind of have the equipment excavated with hoisting function

Technical field

The utility model relates to a kind of equipment, and specifically a kind of equipment having excavation and hoisting function concurrently, belongs to the design ap-plication technical field of excavation and crane hoisting equipment.

Background technology

At oil, natural gas, in the paving work progress of the pipe-networks engineering of the major workss such as water conservancy, the general irrigation canals and ditches all wanting usage mining machine to excavate paving and backfill tubing, use crane allocation and transportation that the pipeline needing to lay is installed, thus, in the process of this type of engineering construction, the mode utilizing crane and excavator to take turns to work is needed to construct, due to unicity and the limitation of crane and excavator function, cause both can only carry out construction operation separately, so, cause equipment investment large, labour intensity is high, efficiency of construction is low, time duration is long, operating expenses is high.

For this reason, Chinese invention patent 201110176932.8, name is called, and " a kind of equipment having excavation and hoisting function concurrently " discloses the equipment simultaneously with excavation and hoisting function, this kind of device makes existing crane have existing function simultaneously, also there is the function of excavator, thus, can effectively overcome equipment investment described above large, labour intensity is high, efficiency of construction is low, time duration is long, operating expenses high defect, but, should " a kind of having concurrently is excavated and equipment of hoisting function " owing to being structurally the bucket arm cylinder of driving dipper is arranged between angle that dipper and swing arm formed, thus there is following defect: 1 is the angle space constraint owing to being subject between dipper and swing arm, bucket arm cylinder dimensions is generally restricted, the oil cylinder compared with large gauge cannot be adopted, dipper working dynamics cannot do larger raising, reduce excacation effect and digging efficiency, 2 is due to structural restriction, dipper work time excavation strength be by the piston rod of bucket arm cylinder do retraction movement to realize, and the retract strength that produces of cylinder piston rod is general less, so, the excavation strength that dipper can produce is subject to further restriction, create a further reduction again excacation effect and digging efficiency.

Summary of the invention

Have for existing the above-mentioned defect excavated with existing for the equipment of hoisting function, the utility model provides a kind of novel equipment with excavation and hoisting function that effectively can overcome above-mentioned defect.

For achieving the above object, the utility model is achieved by following technical method: described a kind of equipment with excavation and hoisting function, and it comprises swing arm, boom cylinder, hoist engine, bucket arm cylinder, expansion coupling, suspension hook; Dipper, bucket cylinder, bucket, supporting seat, it also comprises U-shaped fork-join head, the opening upwards opening grade position of described U-shaped fork-join head is connected across on supporting seat, bearing pin through U-shaped fork-join head the opening opening grade position by supporting seat and U-shaped fork-join head hinged actively.

It is further: one end of dipper is fixedly connected on centre position bottom U-shaped fork-join head.

Opening in U-shaped fork-join head both sides is shaped with boss shoulder near the direction of swing arm, in swing arm bilateral symmetry, a dipper hydraulic cylinder is set, each dipper hydraulic cylinder piston rod end and limit, place boss are takeed on hinged actively, the cylinder bottom position of dipper hydraulic cylinder and the swing arm of place side hinged actively.

The beneficial effects of the utility model: compared with prior art, swing arm both sides are arranged on by driving the dipper hydraulic cylinder of dipper action, by the cooperating with U-shaped fork-join head, structurally the work arm of force of dipper can be designed to the laborsaving arm of force, and mutually do not interfere between the component of work, limited space can be maximally utilised, carry out design arrangement component and make it play maximum function, simultaneously, when also can avoid the angle space be arranged on by dipper hydraulic cylinder between dipper and swing arm, the bucket arm cylinder material collision be easily subject in bucket or bucket causes the defect of damage, it also avoid the angle space constraint owing to being subject between dipper and swing arm simultaneously, bucket arm cylinder dimensions is restricted, cannot adopt the oil cylinder compared with large gauge, dipper working dynamics cannot do larger raising, reduces excacation effect and digging efficiency defect.
