Abstract
The utility model relates to the technical scheme that a kind of special-shaped ridge buster forearm structure takes: the longitudinal section of forearm is T-type structure; the hinged place of oil cylinder of small arm and the hinged place of ridge buster oil cylinder are on the top of forearm longitudinal section, and forearm and large arm hinged place are in the square position of T-type structure post; The hinged place of forearm and ridge buster at the tail end of T-type structure, to keep forearm stress equalization.The utility model has the advantage of: compared with the forearm of case structure, abnormally-structured forearm is length, and the length of large arm and forearm, than increasing, therefore, makes its rigidity be guaranteed, and it is main for being more suitable for that forearm excavates.Meanwhile, after this structure fills iron sand, make structural focus disembark body more closely, therefore complete machine is when power output is larger, assembled machine balance better effects if.3rd, by increasing forearm arm weight, excavator, when processing the hard cubic metre of earth and stone, utilizes the inertia that forearm increases, and improves mining effect.
Description
Technical field
The utility model designs a kind of engineering machinery device, is exactly to increase excavator strength particularly, and to the improvement that excavator mechanical arm aspect is carried out, i.e. a kind of special-shaped ridge buster forearm structure.
Background technology
At present in the engineering constructions such as building, road and bridge, during for harder native stone location, ordinary excavator due to arm strength little, arm is heavy to be difficult to be competent at not, will use arm strength more greatly, special ridge buster that arm is heavier.But when being aimed at the cubic metre of earth and stone hard especially, ridge buster still can be restricted because forearm arm weighs little, and the counterbalance effect of complete machine is poor, can not complete corresponding task efficiently.
Summary of the invention
The utility model is to solve the problems of the technologies described above, provide a kind of special-shaped ridge buster forearm structure, the technical scheme taked is: it is characterized in that: the longitudinal section of forearm is T-type structure; the hinged place of oil cylinder of small arm and the hinged place of ridge buster oil cylinder are on the top of forearm longitudinal section, and forearm and large arm hinged place are in the square position of T-type structure post; The hinged place of forearm and ridge buster at the tail end of T-type structure, to keep forearm stress equalization.
Iron sand is all filled up in described T-shaped forearm inner space.
Explanation of nouns: special-shaped ridge buster forearm structure, referring to forearm structure is not conventional case beam type enclosed construction, but up big and down small, and longitudinal section is T-shaped structure.
The utility model has the advantage of: compared with the forearm of case structure, abnormally-structured forearm is length, and the length of large arm and forearm, than increasing, therefore, makes its rigidity be guaranteed, and it is main for being more suitable for that forearm excavates.Meanwhile, after this structure fills iron sand, make structural focus disembark body more closely, therefore complete machine is when power output is larger, assembled machine balance better effects if.3rd, by increasing forearm arm weight, excavator, when processing the hard cubic metre of earth and stone, utilizes the inertia that forearm increases, and improves mining effect.
Accompanying drawing explanation
Fig. 1 is loosening device large arm, forearm syndeton schematic diagram.
Fig. 2 is the perspective view of forearm.
In figure,
1-forearm, 2-oil cylinder of small arm pin joint, 3-forearm hinge A, 4-ridge buster oil cylinder pin joint, 5-forearm hinge B, 6-oil cylinder of small arm, 7-ridge buster oil cylinder, 8-ridge buster.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, between large arm and forearm 1, connect oil cylinder of small arm, ensure the swing of forearm relative to large arm.Big arm cylinder is arranged in the top of forearm and large arm, and the large chamber work of big arm cylinder during to ensure ridge buster 8 operation, to produce larger digging force.Oil cylinder of small arm longitudinal section is T-type structure, is called lateral part and longitudinal component.In the lateral part of longitudinal section, arrange respectively and oil cylinder of small arm and the hinged pin joint 2,4 of ridge buster oil cylinder, respectively with oil cylinder of small arm 6 and ridge buster oil cylinder 7 hinged, the active force of oil cylinder of small arm, ridge buster cylinder force are added on forearm as load.Big arm of digger is linked together by swing arm hinge and forearm hinge A3, the corner that the longitudinal component that forearm hinge A is arranged on longitudinal section is connected with lateral part, and the setting of this position of articulating point, mainly for avoiding stress influence, improves the application life of forearm.Ridge buster is linked together by ridge buster hinge and forearm hinge B5, and forearm hinge B is arranged on the tail end of the longitudinal component of longitudinal section, makes each stressed in a basic balance of forearm.Adopt the forearm of T-type structure, add large arm and the length ratio of forearm, its rigidity is guaranteed, it is main for being more suitable for forearm excavation.This length is than increasing, and make structural focus disembark body more closely, therefore complete machine is when power output is larger, assembled machine balance better effects if.In addition, in forearm, add filler such as iron sand etc., increase the proportion of forearm, be conducive to machine stress balance, improve mining effect.
Claims (2)
1. a special-shaped ridge buster forearm structure, is characterized in that: the longitudinal section of forearm is T-type structure, and the hinged place of oil cylinder of small arm and the hinged place of ridge buster oil cylinder are on the top of forearm longitudinal section, and forearm and large arm hinged place are in the square position of T-type structure post; The hinged place of forearm and ridge buster at the tail end of T-type structure, to keep forearm stress equalization.
2. special-shaped ridge buster forearm structure according to claim 1, is characterized in that: iron sand is all filled up in described special-shaped forearm inner space.
