Abstract
The utility model discloses a miniature track type hydraulic excavator frame comprising a upper frame, a lower frame and a slewing bearing. The lower frame is welded by an X frame, a left and a right tracks box and a bearing roller support. The left and right tracks are respectively arranged on both sides of the X frame. The bearing roller support is respectively arranged on the left and right track box. The upper frame and the lower frame are connected through the slewing bearing. The characteristics are that the out ring of the upper frame and the slewing bearing are connected through the locating pin. The inner ring of the lower frame and the slewing bearing are connected through the bolt. The track box adopts the asymmetric reversing shape of 'U' structure with a 'V' shaped top. The X frame is a four-plate typed welded structure. The bearing roller shapes like 'L'. The main frame vertical beam of the upper frame shapes like 'T' and is butt welded by a cross plate and an opposite plate. The utility model not only has a beautiful appearance, a high strength and a high stiffness but also has a fine manufacturability; a low cost therefore is an ideal a miniature track type hydraulic excavator frame.
Description
Technical field the utility model belongs to the excavator technical field, relates to a kind of small-sized caterpillar belt formula hydraulic excavating locomotive frame.
The small-sized caterpillar belt formula hydraulic excavating locomotive frame of background technology prior art, its down the crawler belt box in vehicle frame be generally down " U " shape structure of the V-shaped symmetry in " U " shape or top, the X frame is generally " H " shape structure.Advantages such as that this structure of following vehicle frame has is simple in structure, deadweight is lighter, but exist its profiled member manufacturability poor, defective such as overall structure rigidity is little; Body frame longeron on it in vehicle frame adopts the defectives such as form of structure that add steel plate usually, has making simply, and the advantage that quality guarantees easily is bigger but existence is conducted oneself with dignity, the more high defective of cost; The location of last vehicle frame and pivoting support is adopted double-pin location or cylindrical locate mode usually, and the advantage of double-pin location is accurate positioning, and shortcoming is the requirement on machining accuracy height, and assembling is inconvenient, and the advantage of cylindrical location is to be easy to assembling, and shortcoming is that processing is inconvenient.Along with the continuous expansion in small-sized caterpillar belt formula hydraulic crawler excavator market and increasingly sharpening of competition, the user proposes more and more higher requirement to aspects such as the moulding of machine, quality, prices, and this just makes that producer has to do a lot of work in these several respects.
The summary of the invention the purpose of this utility model provides that a kind of handsome in appearance, good manufacturability, cost are low, the small-sized caterpillar belt formula hydraulic excavating locomotive frame of good rigidity, to overcome the deficiencies in the prior art.
The utility model has been taked following technical scheme: the utility model small-sized caterpillar belt formula hydraulic excavating locomotive frame is to improve realization on the basis of existing technology, comprise vehicle frame, following vehicle frame and pivoting support, following vehicle frame is by the X frame, a left side, right-hand track chiain box and holder chain wheeling support constitute through welding, a left side, the right-hand track chiain box is located at the both sides of X frame respectively, holder chain wheeling support is located at a left side respectively, the right side cover tape drum above, last vehicle frame is connected by pivoting support with following vehicle frame, it is characterized in that the said vehicle frame of going up is connected by alignment pin with the outer ring of pivoting support, following vehicle frame is connected by bolt with the inner ring of pivoting support, and said crawler belt box adopts " U " shape structure of the V-shaped asymmetry in top; The X frame is four board-like welded constructions, and this structure is similar to the X shelf structure of large excavator, the intensity height, and rigidity is big; Holder chain wheeling support adopts the bionics design, L-shaped, its structure is similar to the pin of human body, make total seem firmer, attractive in appearance, because the characteristics of minicomputer " little ", the V-shaped asymmetry in this top of crawler belt box are fallen " U " shape structure, make the X frame can smoothly dock with crawler belt box top, prevent from long-pending soil to occur, increase the aperture (rise and prevent long-pending native function) at holder chain wheeling support place simultaneously as much as possible in the junction; The said body frame longeron of going up in the vehicle frame is T-shaped, is formed by a transverse slat and a riser butt welding, and this mode has alleviated body weight greatly, has reduced cost, and rigidity and intensity are all increased to some extent; The said vehicle frame of going up is connected by single finger setting with pivoting support, facts have proved that single finger setting precision can reach designing requirement and instructions for use fully.
The utility model body frame structure for automotive is not only handsome in appearance, and intensity height, rigidity are big, and good manufacturability, and cost is low, is a kind of desirable small-sized caterpillar belt formula hydraulic excavating locomotive frame.
