Developing rapidly of major workss such as As China's oil, natural gas, water conservancy; The laying amount of pipe-networks engineering is also increasing; At present, in the engineering construction process, all be that the mode of utilizing all kinds of cranes and excavator to take turns to work is constructed; Because the unicity and the limitation of crane and excavator function cause both can only carry out construction operation separately.

Currently just lack lifting required in a kind of collector road construction and excavate the multifunctional engineering machinery that function is an one; Avoid in construction; Can only take the equipment such as lifting appliance, excavation machinery of simple function to take turns to carry out construction operation; Cause equipment investment big, labour intensity is high, efficiency of construction is low, time duration is long, and operating expenses is high.

Summary of the invention

Problem to above-mentioned prior art existence; The utility model provides a kind of equipment that has excavation and lifting function concurrently; Its collection lifting is an one with excavating function, in the pipe laying construction, has improved operating efficiency; Alleviate labour intensity, reduced operating expenses, and reduced equipment investment.

To achieve these goals, the utility model is realized through following technical scheme: a kind of equipment that has excavation and lifting function concurrently comprises swing arm, boom cylinder, dipper, bucket arm cylinder, swing arm bearing IV, scraper bowl, suspension hook and hoist engine; Wherein comprise connecting rod I, connecting rod II, be fixedly mounted on the swing arm bearing I and the swing arm bearing II of swing arm middle front part, be fixedly mounted on the swing arm bearing III of swing arm postmedian in order to the parts that connect swing arm and dipper, and the scraper bowl bearing that is fixedly mounted on the dipper rear portion; The rear end of the rear end of connecting rod I and connecting rod II is hinged; The front end of bucket arm cylinder is articulated in the hinged place of connecting rod I and connecting rod II; The front end of connecting rod I is hinged through scraper bowl bearing and dipper; The front end of connecting rod II is hinged through swing arm bearing II and swing arm, and dipper is hinged through swing arm bearing I and swing arm, and bucket arm cylinder is hinged through swing arm bearing III and swing arm.

The know-why of the utility model is: on the basis of excavation and crane hoisting equipment; Swing arm and dipper excavation part are reequiped, in hydraulic system and operating system, set up control original paper, the swing arm after the repacking accordingly; Be the swing arm of digging operation on the one hand; Be the basic arm of hoisting operation on the other hand, and strengthen the amplitude of hoisting operation, excavating gear is made up of swing arm, boom cylinder, dipper, bucket arm cylinder, bucket, bucket cylinder and connecting rod; Be installed in the below of swing arm, realize excavating function; The hoisting operation device is made up of swing arm, telescopic arm, telescopic oil cylinder, and by flexible HYDRAULIC CONTROL SYSTEM, the lifting function is realized in the inside that is installed in swing arm.

The beneficial effect of the utility model is: rational in infrastructure, and reliable in function, convenient practicality; The collection lifting is an one with excavating function, has realized a tractor serves several purposes, has improved utilization rate of equipment and installations and efficiency of construction; Alleviate labour intensity, reduced equipment investment, reduced construction cost.
