Description
Technical field
The utility model relates to a kind of connecting rod, and specifically the reinforced connecting rod of a kind of excavator belongs to engineering machinery field.
Background technology
The axle bed coupling part is adopted bent plate usually before and after the existing excavator connecting rod, gripper shoe, U-shaped plates etc. are welded to connect, because touching welding portion with the antero posterior axis seated connection only is axle bed outer wall about 1/3rd, weld length and contact area are all limited, in case when connecting rod under tension or lateral force, its active force all acts in welded joints, requirement to weld seam on the connecting rod under the abominable operating mode operation is a greatly test, and be easy to cause the cracking of connecting rod weld seam, especially for the excavator that quartering hammer is installed, requirement to the connecting rod weld seam is more harsh, since quartering hammer when work the lateral force to producing under the continuous impact force of connecting rod transmission and the complex working condition, little for existing weld length, the phenomenon main cause of commissure cracking often appears in the connecting rod that contact area is little, for solving the weld cracking problem, usually adopt increasing weld seam and raising weld seam welding quality to reduce the connecting rod cracking, but because contact area is little, fusion length is short, abominable and be equipped with on the excavator of quartering hammer and can not fundamentally solve the connecting rod problem of Cracking in operating mode, but also increased greatly cost, the time of maintenance and maintenance increases, workman's labour intensity increases greatly, has had a strong impact on operating efficiency.
Summary of the invention
Problem for above-mentioned existing existence, the utility model provides a kind of excavator reinforced connecting rod, the use of this connecting rod can effectively solve in operating mode and badly reach the normal connecting rod weld cracking problem that occurs on the excavator that quartering hammer is installed, greatly reduce cost, the time of maintenance and maintenance greatly reduces, workman's labour intensity effectively reduces, and increases work efficiency.
To achieve these goals, the utility model is achieved through the following technical solutions: the reinforced connecting rod of a kind of excavator comprises stiffener, rear end minor axis seat, protecting seat, right plate, U-shaped bent plate, upper bending plate, lower bending plate, left plate, gripper shoe and front end major axis seat; Pass through left plate between front end major axis seat and the rear end minor axis seat; right plate; upper bending plate and lower bending plate fix; left plate and right plate two ends are equipped with the through hole that cooperates with front end major axis seat and rear end minor axis seat; be enclosed within on front end major axis seat and the rear end minor axis seat afterwards by being welded and fixed by through hole; also be welded and fixed by upper bending plate and lower bending plate between left plate and the right plate; be welded and fixed by a stiffener and a U-shaped bent plate between the minor axis seat of rear end; also be welded and fixed by gripper shoe between U-shaped bent plate and the front end major axis seat; also be welded and fixed by gripper shoe and U-shaped bent plate between upper bending plate and the lower bending plate; rear end minor axis block hole axis keeps overlapping; all be welded with a protecting seat on front end major axis seat and the rear end minor axis seat; upper bending plate and lower bending plate are with after front end major axis seat and rear end minor axis seat cooperate; upper bending plate and lower bending plate end pieces leave certain slit; its space is filled fixing in the reinforcement between bending plate and lower bending plate and front end major axis seat and the rear end minor axis seat by welding.
The beneficial effects of the utility model are: the utility model is compared with existing connecting rod, the side plate two ends offer two holes that cooperate with major axis seat and minor axis seat, biside plate be welded and fixed after two axle beds cooperate, vertical folding bent plate two ends are provided with the arc section that cooperates with major axis seat and minor axis seat, after cooperating with major axis seat and minor axis seat, fixes by weld seam the vertical folding bent plate, also be provided with the rectangular opening that cooperates welding with gripper shoe on the vertical folding bent plate, the utility model is in the power transmittance process, different from existing connecting rod, two side plates and vertical folding bent plate all bear pressure and lateral force, effectively avoided existing connecting rod to only depend on the problem of weld seam bearing tension and lateral force, this utility model is more firm, prolonged the application life of connecting rod, the time of maintenance and maintenance greatly reduces, improve operating efficiency and operating personnel's work incentive, and had very wide market prospects.
