Description
Technical Field
The invention relates to the field of auxiliary tools of hydraulic excavators, in particular to a hydraulic auxiliary tool arranged between a movable arm and a working device of a hydraulic excavator.
Background
When the hydraulic excavator is in construction operation, because the working mode of the excavator is fixed to only backhoe operation or backhoe operation, in many working scenes, one excavator cannot simultaneously complete the two operations of the backhoe and the backhoe, and because the working mode of the backhoe or the backhoe excavator can only enable the bucket to achieve the operation purposes of parallel operation (backhoe excavator) from the far end of the direction of the cab of the excavator to the cab or parallel operation (backhoe) from one end of the cab to the far end of the cab, excavation, leveling, hoisting, carrying and the like, when the backhoe operation is needed at the same time, two different excavators are needed, if the backhoe and the backhoe are replaced on the same excavator, the process wastes 1 to 2 hours each time, and therefore the actual use time of the excavator is shortened. When the working device of the excavator needs to work at a specific angle, a driver is required to adjust the position of the vehicle body to enable the working device of the excavator to be aligned to a construction point needing to work, but along with the increasingly strengthened national protection on mountain and forest land and the continuous construction of modern cities, the moving range of the hydraulic excavator is reduced in a plurality of construction scenes, the excavator is limited by the space area, so that the driver cannot align the angle of the working device to an accurate construction point in a mode of adjusting the position of the vehicle body, and dead angles relative to the excavator can be formed in most of the working scenes. At this time, a large amount of manpower is needed to clean dead corners which cannot be constructed by the excavator in the most original mode, leveling, excavating and other operations are matched with the excavator to complete construction, so that the construction cost is increased, the construction period is prolonged, in the process of road construction and building sewer line laying, a lot of road strip stone cement pipes which cannot be moved by manpower are arranged, materials with small reinforcing steel bar volume and large weight are limited by the shape of an excavator bucket of the excavator and cannot be picked up, at the moment, some excavators are provided with clamps, the clamps are required to be disassembled to mount buckets of the excavator at the original bucket positions when the clamps are replaced, when excavation operation is needed, the clamps are disassembled to mount the buckets, 1 to 2 hours are wasted in the process each time, the effective service time of the excavator is greatly reduced, and when few materials needing to be transported and lifted, another method is that the lifting rings behind the excavator buckets are manually matched to lift the materials The material handling device comprises a carrying device, a lifting device and a lifting device, wherein the carrying device is used for carrying materials, the materials need to be manually bound by a steel wire rope in the lifting process, the materials need to be manually unbound after being lifted and carried to a required place, if the materials cannot be carried at one time, the materials need to be bound again, the materials need to be lifted and bound, the operation target can be completed only by repeated operation, the process is extremely complicated, the carrying efficiency of the materials with small size and large weight of the excavator is low, and the construction time is prolonged and the cost is increased due to the additional manual matching. In the process of excavating pipelines such as a tap water pipeline, a thermal pipeline, a natural gas pipeline and the like, because the required pipe diameters of the pipelines are different, the requirements for the width of an excavated ditch are also different, at the moment, buckets with different widths are required to excavate the ditch, the time from 40 minutes to 60 minutes is wasted when the buckets with different widths are replaced, and the actual use duration of the excavator is influenced.
