Description
Technical field
The present invention relates to a kind of Track-wheel type excavator and method of work thereof, belong to the technical field excavating heavy industry machinery.
Background technology
Common excavator structure comprises: engine installation, equipment, swing type mechanism, steering unit, transmission device, traveling gear and auxiliary facilities.Described excavating machine is divided into traxcavator and wheel shovel according to walking manner, the excavating machine of different walking manner is selected: when work road surface evenness according to the Site Type of executing the task, multiselect wheel shovel, it is convenient that it has walking, without the need to external delivery locomotive to advantages such as its deliverys; When the road surface that works is muddy, multiselect traxcavator carries out work, but it is large that its shortcoming is surface damage over the ground of walking on asphalt flooring and plane earth, and strain is caused to crawler belt, greatly reduce the life-span of crawler type walking mechanism, need the vehicle increasing delivery excavating machine separately to transport traxcavator for this reason, considerably increase construction and maintenance cost.
In order to allow excavating machine adapt to multiple path, Chinese patent CN2483223 relates to the Amphibious type excavating machine of shallow water area or wetland use.Solve the halfway problem of desilting.It is characterized in that: crawler belt (9) has the hollow transverse slat of spaced-apart fins to be formed by connecting by be fixed on chain (10) some; and chain (10) is some clamping plate two ends clamping ball (15) compositions, its chain (10) invests in floating drum (3) the top layer groove that inner chamber is sky body; Vehicle body (1) bottom is fixed on the crossbeam (2) of floating drum (3) by rotating disk (7), rotating disk (7) is connected with and crawler belt (9) equidirectional suction pipe (4) simultaneously, suction pipe (4) other end, by the fixing suction nozzle (6) of HM Hydraulic Motor (5), is fixed with the transmission shaft (8) that gear coordinates with chain (10) in floating drum (3) termination.There is thorough, the fireballing feature of desilting, be adapted at shallow water area or wetland use.But this patent just carries out conversion walking mode for shallow water and wetland, and be not suitable for level land in existing construction, the change of muddy physical features uses, and can not solve the defect of excavating machine transition voluntarily.
Chinese patent CN202108065U relates to a kind of buoyancy box crawler excavator for environment-protective desilting.Comprise excavating machine to get on the bus and get off, described in get off as air buoyancy tank crawl structure, be enclosed with chain outside described buoyancy tank, described chain be provided with track shoe; Be provided with propelling unit inside described buoyancy tank, described propelling unit is hydraulic motor driving propeller; Be provided with supporting leg outside described buoyancy tank, described supporting leg is that hydraulic ram controls supporting leg; Complete machine afterbody is provided with CD-ROM drive motor.It can solve the dredging in current inland river and desilting is still the problem adopting Traditional Man mode of operation at present, overcomes deep drawing shortcoming; It has the soft regions such as marsh of can freely coming in and going out, and can float boat in water, can at underwater work, and maneuvering performance is good, the advantage that operation is stable, is applicable to the digging operation in coastal intertidal zone, marsh, beach, inland river, lake, realizes amphibious operation.This patent also just change by crawler belt, buoyancy tank two kinds of walking modes, but for still needing outside transport vehicle to consign during the transition of level land, not only add use cost, and the vibrations in delivery process also can cause the mechanical wear of other parts of excavating machine.
