Abstract
The utility model discloses an excavator compressor machinery straining device, including compressor, runing rest, compressor fixed bolster, compressor fixed mounting on the runing rest, the runing rest is installed on the compressor fixed bolster in order can dismantle fixed mode. Because the utility model discloses a compressor fixed mounting is on the runing rest, and the runing rest is installed on the compressor fixed bolster and can be moved at relative compressor fixed bolster under adjusting bolt's the effect in order can dismantle fixed mode, adjusts the relative position of compressor, does not have the compressor take -up pulley in traditional structure, makes the utility model discloses a life is longer.
Description
Technical field
The utility model relates to a kind of excavator, particularly relates to a kind of excavator compressor mechanical tensioning mechanism.
Background technique
As shown in Figure 1, existing compressor mechanical tensioning mechanism realizes primarily of Idle wheel 2, its structure is: compressor 1 and compressor Idle wheel 2 are arranged on engine cylinder-body, moved up and down by the bolt adjusting Idle wheel 2, make belt 11 tensioning gradually of compressor 1, after belt 11 reaches predetermined rate of tension requirement, stop tensioning.Idle wheel 2 inside is bearing structure, and under being in tensioning state for a long time, make the bearing length time bear pressure, working life is limited, within frequent 1000-1500 hour, must change, customer using cost is increased, and increase the unit failure rate of main engine factory.
Summary of the invention
The purpose of this utility model is the excavator compressor mechanical tensioning mechanism providing a kind of long service life.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of excavator compressor mechanical tensioning mechanism, comprises compressor, runing rest, compressor fixed support; Described compressor is fixedly mounted on runing rest, and runing rest is arranged on compressor fixed support in detachably fixing mode.
The support bracket fastened side wall upper part of described compressor is provided with curved swivelling chute, the side wall upper part of runing rest is worn by upper clamping bolt and is connected in the support bracket fastened swivelling chute of compressor, the lower sidewall of runing rest is fixed on the support bracket fastened lower sidewall of compressor by lower clamping bolt, to be spirally connected an adjustment bolt at compressor fixed support end wall, this adjustment bolt leans on the end wall of runing rest through after compressor fixed support end wall.
After adopting such scheme, because compressor of the present utility model is fixedly mounted on runing rest, runing rest is arranged on compressor fixed support in detachably fixing mode and also can moves relative to compressor fixed support under the effect of adjustment bolt, the relative position of adjustment compressor, without the compressor Idle wheel in conventional construction, make longer service life of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the axonometric drawing commonly using compressor mechanical tensioning mechanism;
Fig. 2 is axonometric drawing of the present utility model;
Fig. 3 is three-dimensional exploded view of the present utility model.
Embodiment
As shown in Figure 2 and Figure 3, the utility model is a kind of excavator compressor mechanical tensioning mechanism, comprises compressor 1, runing rest 2, compressor fixed support 3.
Described compressor 1 is fixedly mounted on runing rest 3 by construction bolt 11.
The side wall upper part of described compressor fixed support 3 is provided with curved swivelling chute 31, the side wall upper part of runing rest 2 is worn by upper clamping bolt 4 and is connected in the swivelling chute 31 of compressor fixed support 3, the lower sidewall of runing rest 2 is fixed on the lower sidewall of compressor fixed support 2 by lower clamping bolt 5, to be spirally connected an adjustment bolt 6 at compressor fixed support 3 end wall, this adjustment bolt 6 is through leaning on the end wall of runing rest 2 after the screw 32 of compressor fixed support 3 end wall, runing rest 2 is arranged on compressor fixed support 3 in detachably fixing mode.
Adjusting method of the present utility model:
With spanner twisting adjustment bolt 6, allow runing rest 2 and compressor 1 entirety rotate in the swivelling chute 31 of compressor fixed support 3, make air-conditioning belt 10 tensioning gradually, after reaching tension force, stop tensioning.
Emphasis of the present utility model is just: runing rest and compressor fixed support can relative movements.
The above, be only the utility model preferred embodiment, runing rest and the support bracket fastened form structure of compressor can have multiple, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the utility model claim and description with modify, all should still belong in scope that the utility model patent contains.
