Abstract
A reinforced caterpillar track link consists of a pin bush hole, a front rigid hole, a track surface, a rear rigid hole, a pin shaft hole, a front bolt hole, a rear bolt hole and a substrate, and the reinforced caterpillar track link is characterized in that the front end of the substrate is provided with the pin bush hole, the rear end of the substrate is provided with the pin shaft hole, the upper part of the substrate is provided with the track surface, the inner side of the pin bush hole is provided with the front rigid hole, the inner side of the pin shaft hole is provided with the rear rigid hole, the lower end of the front rigid hole is provided with a front bolt hole, and the lower end of the rear rigid hole is provided with a rear bolt hole. The reinforced caterpillar track link has beneficial effects that the structure design is reasonable, stress concentration is not easy to form, and the service life is long.
Description
Technical field
The utility model belongs to mechanical equipment technical field, says more specifically the reinforcement track link rail that a kind of excavating machine uses.
Background technology
The track link rail of prior art generally adopts monotrysian type, and material is 40Mn2H or 35GMoA, requires rail level hardness 50～58HRC, and tensile strength is not less than 932N/mm
2Chain rail joint is the vital part in the shovel crawler track rail assembly, because operating environment is relatively poor, it in use, bear periodic pressure and huge working pulling force, a chain rail saves the transient pressure that bears and substantially exceeds its tensile strength values, in this case, chain rail joint produces periodically elastic deformation, because structure design is unreasonable, this elastic deformation stress easily forms stress at place, waist hole and concentrates, and chain rail joint is broken, service life is short, causes larger economic loss.
Summary of the invention
In order to address the above problem, the utility model provides a kind of reasonable in design, being difficult for forming stress concentrates, the reinforcement track link rail of long service life, its concrete scheme is: described reinforcement track link rail is by the guide hole, front rigidity hole, rail level, rear rigidity hole, pin shaft hole, front bolt hole, rear bolt hole, matrix composition, the front end that it is characterized in that matrix arranges the guide hole, the rear end of matrix arranges pin shaft hole, the top of matrix arranges rail level, the inboard in guide hole arranges front rigidity hole, the inboard of pin shaft hole arranges rear rigidity hole, and the lower end in front rigidity hole arranges front bolt hole, and the lower end in rear rigidity hole arranges rear bolt hole.
The beneficial effects of the utility model are reinforcement track link rail reasonable in design, are difficult for forming stress and concentrate long service life.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model; In the accompanying drawing:
1. guide hole, 2. front rigidity hole, 3. rail level, 4. rear rigidity hole, 5. pin shaft hole, 6. front bolt hole, 7. rear bolt hole, 8. matrix.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail, so that the public grasps implementation method of the present utility model better, the utility model specific embodiment is: described reinforcement track link rail is by guide hole 1, front rigidity hole 2, rail level 3, rear rigidity hole 4, pin shaft hole 5, front bolt hole 6, rear bolt hole 7, matrix 8 forms, the front end that it is characterized in that matrix 8 arranges guide hole 1, the rear end of matrix 8 arranges pin shaft hole 5, the top of matrix 8 arranges rail level 3, the inboard in guide hole 1 arranges front rigidity hole 2, the inboard of pin shaft hole 5 arranges rear rigidity hole 4, the lower end in front rigidity hole 2 arranges front bolt hole 6, and the lower end in rear rigidity hole 4 arranges rear bolt hole 7.
The beneficial effects of the utility model are reinforcement track link rail reasonable in design, are difficult for forming stress and concentrate long service life.
