Description
Technical field
The present invention relates to a kind of crawler belt wheel shovel and method of work thereof, belong to the technical field of 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, select the excavating machine of different walking manners according to the Site Type of executing the task: when the work road surface is smooth, the multiselect wheel shovel, it is convenient that it has walking, need not external delivery locomotive to advantages such as its deliverys; When the work road surface is muddy, multiselect carries out work with traxcavator, but its shortcoming is large in the over the ground surface damage of walking of asphalt flooring and plane earth, and crawler belt is caused strain, greatly reduce the life-span of crawler type walking mechanism, the vehicle that for this reason needs to increase separately the delivery excavating machine transports traxcavator, has greatly increased 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 territory or wetland use.Solved the halfway problem of desilting.It is characterized in that: crawler belt (9) has the hollow transverse slat of interval fin to be formed by connecting by being fixed on some on the chain (10), and chain (10) is some clamping plate two ends clamping ball (15) composition, and its chain (10) invests in the floating drum that inner chamber is empty body (3) the top layer groove; 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 the equidirectional suction pipe of crawler belt (9) (4) simultaneously, suction pipe (4) other end passes through fixedly suction nozzle (6) of HM Hydraulic Motor (5), is fixed with the transmission shaft (8) that gear cooperates with chain (10) in floating drum (3) termination.Have thorough, the fireballing characteristics of desilting, be adapted at shallow water territory or wetland and use.But this patent is just carried out the conversion walking mode for shallow water and wetland, and is not suitable for the variation use of level land, muddy physical features in the existing construction, can not solve the defective that excavating machine is cut to voluntarily.
Chinese patent CN202108065U relates to a kind of buoyancy box crawler excavator for environment-protective desilting.Comprise that excavating machine gets on the bus and get off, described getting off is the air buoyancy tank crawl structure, and the described buoyancy tank outside is enclosed with chain, on the described chain track shoe is installed; Described buoyancy tank inboard is provided with propelling unit, and described propelling unit is hydraulic motor driving propeller; The described buoyancy tank outside is provided with supporting leg, and described supporting leg is hydraulic ram control supporting leg; The complete machine afterbody is provided with CD-ROM drive motor.Its dredging and desilting that can solve present inland river is still the problem that adopts the Traditional Man mode of operation at present, overcomes deep drawing shortcoming; It has the soft regions such as the marsh of can freely coming in and going out, and can float boat in water, can be at underwater work, and maneuvering performance is good, and 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, two kinds of walking modes of buoyancy tank, yet still need outside transport vehicle to consign when cutting to for the level land, not only increased use cost, and the vibrations in the delivery process also can cause the mechanical wear of other parts of excavating machine.
