Abstract
The utility model discloses a round type retractable tracked chassis comprising a center rotating frame. Retractable guiding frames connected with a left track frame and a right track frame assembly are arranged on the two sides of the center rotating frame. The round type retractable tracked chassis is characterized in that the retractable guiding frames take the shape of a column or a cylinder, the left and the right track frame assemblies are provided with guiding cylinders corresponding to the circular guiding frames, and a slide bearing is nested in each guiding cylinder. Compared with the prior art, the utility model has the advantages of circular retractable guiding frames, convenient processing, high production efficiency, convenient maintenance and the like.
Description
One, technical field
The utility model relates to the telescopic chassis that a kind of construction machinery and equipment is used to expand, and is specifically related to a kind of expansion bracket and is circular flexible crawler body.
Two, background technology
Along with the development of existing society, construction machinery and equipment is by a large amount of uses, the construction machinery and equipment with flexible crawler body is all the more so; Existing flexible crawler body comprises center steering frame and left and right track frame assembly, and the center steering frame is connected with left and right track frame assembly by expansion bracket.
Current, domestic or international flexible caterpillar chassis no matter, its flexible guide frame all adopts rectangle or square sectional, four flexible guide frames of center steering frame move in the rectangular opening of track frame, the lower surface of square-section is the contact carrying surface, impact load before and after the facade of both sides bears, and upper surface leaves the gap.
Rectangle or square are adding fabrication properties complexity in man-hour, as at the center steering frame, need at least three outerplanars of each flexible guide frame of milling, especially base area is bigger, the milling work capacity is big, except the parallelism that guarantees four each contact surfaces of flexible guide frame bottom, also to take into account the squareness of each flexible guide frame facade and bottom surface; Again at track frame, milling rectangle or square sectional hole get at least three inner planes, processing technology is more complicated, the four-wheel one band mounting interface that involves is not said, only two its processing capacities of rectangular opening and difficulty of processing are just not little, be subjected to the influence of lathe working head volume, the four sides of rectangle endoporus and four corners can not be finished in disposable milling, need to weld again behind a part of face of processing, rectangular opening is finished in completion, and then processing, welding causes weldment partly to be out of shape, and clamping causes working accuracy to reduce once more.
Obviously, two crucial weldments of the flexible caterpillar chassis of processing have proposed high request to the processing characteristics of lathe.The slave unit life-span is considered, flexible guide frame rigidity in the track frame rectangular opening moves, need grease-added lubricated for reducing friction, though have grease to increase lubricant effect, because equipment quality is big, its contact pressure is also big, it is big that rigid contact surfaces produces friction force, the chassis is flexible must cause the permanent wearing and tearing of contact surface, causes the parallelism difference of four rectangular opening bottom surfaces, influences the use of equipment when serious.
Three, summary of the invention
The utility model provides a kind of expansion bracket to be the flexible crawler body of the round formula circular, easy to process, that production efficiency is high, easy to maintenance at above weak point.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of round formula crawler body that stretches, comprise the center steering frame, the both sides of center steering frame are provided with flexible guide frame, flexible guide frame is connected with left and right track frame assembly, described flexible guide frame is cylindrical or cylindrical shape, left and right track frame assembly is provided with and the circular flexible corresponding guide cylinder of guide frame, is with plain bearing in the guide cylinder, and flexible guide frame slides along plain bearing in guide cylinder; The number of center steering frame both sides expansion bracket can design as required.
Above-mentioned flexible guide frame is that flange is connected with the center steering frame.
The beneficial effects of the utility model show:
The round section that adopt on the telescopic chassis of the flexible nested structure of circle formula is significantly improved and is finished the fabrication properties at member in critical position, when reducing difficulty of processing, significantly reduced machining amount, improved production efficiency, also saved steel, reduced the weldment cost.
The flexible guide frame of round section, guide cylinder fixedly change bolted into by welding, add center steering frame and flexible guide frame, guide cylinder separate machined in man-hour, framing member has significantly reduced oad on Width, this has also reduced the requirement to the platen operating range.
Plain bearing adopts oil-less self-lubricating bearing, and environmental adaptation is wide, has very high strength at repeated alternation, load-carrying capacity, impact resistance, withstanding corrosion and bearing surface performance preferably; And maintaining is convenient, only by regularly rotating the adjust a bearing direction, can reduce the rigidity wearing and tearing of framing member, changes in case of necessity to get final product.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is left track frame assembly structure scheme drawing;
Fig. 3 is a center steering shelf structure scheme drawing.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
Describe below in conjunction with caterpillar chassis, as shown in Figure 1: a kind of round formula crawler body that stretches comprises center steering frame 1, left track frame assembly 2, right side track frame assembly 3.
Described center steering frame 1 as shown in Figure 3, comprise revolution support body 11, revolution support body 11 both sides are provided with the flexible guide frame 12 of round formula, and the flexible guide frame 12 of circle formula has six, every side is provided with three, and flexible guide frame 12 is by circular flange dish and revolution support body 11 bolted connections.
Described track frame assembly as shown in Figure 2, comprise four-wheel one band, with the flexible guide frame 12 corresponding guide cylinders 4 of circle formula, guide cylinder 4 is captiveed joint with the track frame assembly by track frame weldment 5, be arranged with plain bearing 6 in the guide cylinder 4, for preventing that plain bearing 6 from rotating the section bolt up of plain bearing 6.
The guide frame 12 that will stretch during use is inserted in the guide cylinder 4 to be installed.In the use, plain bearing 6 is rotated adjustment, makes its wearing and tearing evenly, when wearing and tearing were serious, the plain bearing 6 that dismounting and change is new got final product.
Stretching structure of the present utility model not only can be used for the flexible crawler body of crawler belt, also can be used for non-caterpillar telescopic crawler body; The flexible guide frame number of center steering frame upper flange bonded assembly also can design as required.
