Abstract

Disclosed is a working device with an excavation function and a lifting function. According to the adopted main technical scheme, two symmetric supporting bases are arranged on one side of the upper portion of a movable arm. A bucket rod is arranged between opening gears of the two supporting bases. A hinge pin penetrates through the supporting bases so that the bucket rod and the supporting bases can be movably hinged together. The bucket rod is divided by the hinge pin on the hinge joint into a resisting arm and a driving arm, and the resisting arm and the driving arm are arranged on the two sides of the hinge pin. A bucket rod hydraulic cylinder is placed on the lower side of the movable arm, the end of a piston rod of the bucket rod hydraulic cylinder and the inner side of the top of the driving arm are movably hinged together, and the bottom of a cylinder body of the bucket rod hydraulic cylinder and the movable arm are movably hinged together. An excavation bucket is movably hinged to the end of the resisting arm, and an excavation bucket hydraulic cylinder is arranged on the resisting arm. According to the invention, the existing device space can be utilized to the maximum extent, and the working performance of the device can be optimized.

Description

A kind of have the equipment excavated with hoisting function

Technical field

The present invention relates to a kind of equipment, 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

The object of the invention is to: for existing, there is the above-mentioned defect excavated with existing for the equipment of hoisting function, the invention provides a kind of novel equipment with excavation and hoisting function that effectively can overcome above-mentioned defect.

For achieving the above object, the present invention is achieved by following technical method: described a kind of equipment with excavation and hoisting function, it comprises swing arm (1), be arranged on the hoist engine (2) of swing arm (1) back near lower end position, be arranged on the telescopic arm (7) that swing arm (1) is inner, be arranged on the assembly pulley (8) of final stage telescopic arm (7) end, suspension hook (9) is connected with described assembly pulley (8) by wire rope, described hoist engine (2) is by realizing the driving hoisting or transfer to suspension hook to the winding of steel wire or release, at swing arm (1), one or two swing arm hydraulic cylinders (3) are set near the position of below, piston rod top and the swing arm (1) of this swing arm hydraulic cylinder (3) are hinged actively, the effect of effect lifting swing arm (1) amplitude of this swing arm hydraulic cylinder (2), two symmetrical supporting seats (6) are being fixedly installed near upper position side with the swing arm (1) of suspension hook (9) the same side, opening between shelves of two supporting seats (6), dipper (10) is set, bearing pin (12) is hinged actively by dipper (10) and two supporting seats (6) through two supporting seats (6), dipper (10) is divided into resistance arm (13) and actuating arm (14) two parts by described bearing pin (12) at pin joint place, resistance arm (13) and actuating arm (14) are in the both sides of bearing pin (12), the total length of resistance arm (13) is greater than the total length of actuating arm (14), the U-shaped space bottom that can be formed by two supporting seats (6) and swing arm (1) in the process that described actuating arm (14) rotates around bearing pin (12), be sidelong under swing arm (1) and a dipper hydraulic cylinder (4) is set, end and actuating arm (14) the inside top position of the piston rod of described dipper hydraulic cylinder (4) are hinged actively, cylinder base and the swing arm (1) of described dipper hydraulic cylinder (4) are hinged actively, a hinged bucket (5) actively in the end of resistance arm (13), resistance arm (13) is arranging a bucket hydraulic cylinder (11), described bucket hydraulic cylinder (11) plays the effect controlling bucket (5) and work.

Beneficial effect: after the present invention adopts said method, has following beneficial effect: 1, compared with prior art, has the simple advantage of structure; 2, the supporting seat (6) owing to arranging makes the space between dipper (10) and swing arm (1) increase, dipper hydraulic cylinder (4) is arranged on and can obtains larger installing space by between swing arm (1) and dipper (10), be convenient to adopt the dipper hydraulic cylinder compared with large gauge, better can optimize the performance of whole equipment; 3, owing to dipper (10) to be arranged to resistance arm (13) and actuating arm (14) two parts, and actuating arm (14) is rotated around bearing pin (12), thus, the strength of dipper (10) excacation provided by the piston-less lumen operating pressure of bucket arm cylinder (4), thus can produce larger work strength, be conducive to the performance improving service behaviour and equipment; 4, because just dipper (10) is arranged to resistance arm (13) and actuating arm (14) two parts, and actuating arm (14) is rotated around bearing pin (12), dipper (10) forms laborsaving lever, can play the performance of machinery to greatest extent.
