Description
Technical field
The power shovel that the utility model relates to a kind of bogie wheel mounting structure that increases the service life and has this bogie wheel mounting structure.
Background technology
The excavating machine principal feature is that power is big, the efficient height, can finish manpower the engineering that can not finish, increase work efficiency.According to the difference of type of drive, excavating machine can be divided into two kinds of internal combustion engine drive excavating machine and driven by power excavating machines.Wherein, electric excavator can be described as power shovel again.Power shovel is the major equipment that the ore deposit ground is peeled off, and it plays an important role for mining.
A kind of power shovel, its traveling gear and be assemblied in digging mechanism, swing type mechanism and lift system on the traveling gear, traveling gear has crawler belt, drive wheel and bogie wheel.See also Fig. 1 to Fig. 3, each bogie wheel mounting structure 10 comprises wheel shaft 11, bogie wheel 12, two track frames 13, clip 14 and locatings plate 15.Wheel shaft 11 has draw-in groove 112 and positioning groove 114, and draw-in groove 112 and positioning groove 114 lay respectively at and prop up the relative both sides of wheel shaft 11.Bogie wheel 12 and track frame 13 are arranged between the draw-in groove 112 and positioning groove 114 that props up on the wheel shaft 11, and bogie wheel 12 is between two track frames 13.Clip 14 is fixed on the draw-in groove 112, and locating plate 15 then is matched with positioning groove 114.Locating plate 15 can prevent that the wheel shaft 11 from rotating and moving axially to the right, and then 14 of clips can prevent that the wheel shaft 11 from moving axially left.
Above-mentioned power shovel in use, because the work common unfairness in ground, can make the suffered load variations of each bogie wheel 12 bigger, therefore be easy to generate bigger local stress on the wheel shaft 11, and a wheel shaft 11 is ruptured at draw-in groove 112 or locating plate 15 outsides, and then the service life of shortening bogie wheel mounting structure 10, influence the use of power shovel.
The utility model content
In view of above-mentioned condition, be necessary the power shovel that a kind of bogie wheel mounting structure that increases the service life is provided and has this bogie wheel mounting structure.
A kind of bogie wheel mounting structure, it comprises a wheel shaft, bogie wheel, first track frame and second track frame, bogie wheel, first track frame and second track frame are arranged on the wheel shaft, and bogie wheel is between first track frame and second track frame.Wherein, prop up wheel shaft and have mating holes at an end of the second track frame side; The bogie wheel mounting structure also comprises fixed cover, and it is arranged on the wheel shaft and with second track frame and fixes, and fixed cover has fixed orifice; Bolt passes fixed orifice and matches with mating holes, so that fixed cover fixes with a wheel shaft.
A kind of power shovel, it comprises traveling gear and is assemblied in digging mechanism, swing type mechanism and lift system on the traveling gear, and traveling gear has a plurality of above-mentioned bogie wheel mounting structures.
Above-mentioned bogie wheel mounting structure and have the power shovel of this bogie wheel mounting structure, owing to adopt a bolt fixed cover and a wheel shaft, avoided a wheel shaft diameter sudden change to occur at the fixed cover place, therefore can increase the structural strength of a wheel shaft, and minimizing stress concentration, and then reduce the phenomenon that fracture takes place a wheel shaft, and prolong the service life of bogie wheel mounting structure, make things convenient for the use of power shovel.

The specific embodiment
Below in conjunction with drawings and Examples bogie wheel mounting structure of the present utility model and power shovel with this bogie wheel mounting structure are described in further detail.
See also Fig. 4, be depicted as the power shovel 200 of the utility model preferred embodiments, it comprises traveling gear 202 and is assemblied in digging mechanism 204 on the traveling gear 202, swing type mechanism 206 and lift system 208.
Further, in the present embodiment, bogie wheel mounting structure 20 also comprises plain bearing 26 and thrust bearing 27.Wherein, plain bearing 26 is arranged between a wheel shaft 21 and the bogie wheel 22; Thrust bearing 27 then is arranged between bogie wheel 21 and first track frame 23 and the bogie wheel 21 and second track frame 24.
Above-mentioned bogie wheel mounting structure 20 and have the power shovel 200 of bogie wheel mounting structure 20, owing to adopt a bolt fixed cover 25 and a wheel shaft 21, avoided a wheel shaft 21 the diameter sudden change to occur in fixed cover 25 junctions, therefore can reduce stress concentration takes place, strengthen the structural strength of a wheel shaft 21, and then reduce the phenomenon that fracture takes place a wheel shaft 21, and prolong the service life of bogie wheel mounting structure 20, make things convenient for the use of power shovel 200.In addition, first track frame 23 does not fix away from a side of bogie wheel 22, but makes the relative motion between a track frame 23 and the wheel shaft 21 of winning, thereby also can prevent to be out of shape the tensile stress that produces because of first track frame 23.
In addition, those skilled in the art also can do other variation in the utility model spirit, and certainly, the variation that these are done according to the utility model spirit all should be included in the utility model scope required for protection.
