Abstract
The utility model discloses an excavator handrail belongs to engineering machine parts field for the excavator, it includes main steel pipe, lower mounting panel, last mounting panel, be equipped with the outer tube on going up the mounting panel, be equipped with interior sleeve pipe in the outer tube, the both ends of main steel pipe respectively with mounting panel, interior bushing down. In view of above -mentioned technical scheme, the utility model discloses can reduce and cause the cracked problem of handrail because of the excavator tonnage increases, it is good to have a resistance to shock, simple structure, the characteristics of economy and durability.
Description
Technical field
The utility model belongs to engineering machinery accessory field, specifically, particularly relates to a kind of excavator handrail.
Background technology
At present along with the increase of excavator tonnage, the handrail on excavator along with the vibration of excavator further violent, the phenomenon of handrail fracture is very general.Armrest conventional on excavator is generally two ends and respectively adopts one section of round steel to be welded on lower installation board, the middle structure adopting fastener for connection, and because of welding and installation distortion, and stress is concentrated, and often occurs fracture.Also bending fixing after having part to adopt end sleeve, left and right directions shock resistance is general.Some employing two ends welding of middle support of reinforcing connects, and causes welding deformation, there is internal stress.
Summary of the invention
The purpose of this utility model is to provide a kind of excavator handrail, and it can reduce the problem causing handrail to rupture because excavator tonnage increases, and has resistance to shock good, and structure is simple, the feature of economy and durability.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of excavator handrail, comprise main steel pipe, lower installation board, upper mounting plate, described upper mounting plate is provided with outer tube, is provided with inner sleeve in outer tube, and the two ends of described main steel pipe are connected with lower installation board, inner sleeve respectively.
Say further, be also provided with stay pipe between the main steel pipe described in the utility model and upper mounting plate, the two ends of stay pipe are connected with main steel pipe and upper mounting plate respectively.
Say further, the stay pipe described in the utility model and with bolts between upper mounting plate.
Say further, the stay pipe described in the utility model is connected with bolt by embedding pipe with upper mounting plate.
Say further, the embedding pipe described in the utility model comprises embedded pipe, embedding pipe, and described embedding pipe, embedded Guan Jun are positioned at stay pipe.
Say further, the section of the connecting portion of the embedded pipe described in the utility model, embedding pipe and stay pipe and bolt is tabular structure.
Say further, embedding pipe, stay pipe and embedded pipe are fixed on upper mounting plate by packing ring by the bolt described in the utility model.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can reduce the problem causing handrail to rupture because excavator tonnage increases, and has shock resistance good, and structure is simple, the feature of economy and durability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, main steel pipe; 2, lower installation board; 3, stay pipe; 4, upper mounting plate; 5, outer tube; 6, inner sleeve; 7, bolt; 8, packing ring; 9, embedding pipe; 10, embedded pipe.
