Abstract
The utility model relates to a kind of automatic takeup of gig, and it comprises gig housing, screw rod, stop nut, spring, setting nut and captive nut, pressing plate and driven subassembly; Described pressing plate covers on gig housing, driven subassembly is fixed on pressing plate, adapter plate passing on gig housing of screw rod, other end is connected with pressing plate by captive nut, spring is through on screw rod, adapter plate propping up on gig housing of described spring, other end is connected with screw rod with setting nut.The utility model compact conformation, reasonable; By spring in addition tensioning can not produce excessive downforce to chain so that damage equipment, the lasting dynamics of spring has also been avoided needing manually often go to adjust simultaneously; It is both convenient to regulate like this, saves time not only but also laborsaving.Just can reflect intuitively in addition the elasticity of spring by the distance between the adapter plate on observation stop nut and gig housing.
Description
Technical field
The utility model relates to a kind of automatic takeup of gig, for regulating the plate chain of gig or the degree of tension of loop chain, belongs to mechanical equipment technical field.
Background technology
When gig promotes aggregate, driven unit drives driven subassembly to move together by plate chain or loop chain, therefore must ensure that plate chain or loop chain have certain degree of tension.Due to long-term operation, plate chain or loop chain can extend gradually or wear and tear, and cause chain to skid, therefore must be by addition tensioning of control apparatus.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, a kind of automatic takeup of gig is provided, this device by spring in addition tensioning can not produce excessive downforce to chain so that damage equipment, the lasting dynamics of spring has also been avoided needing manually often go to adjust simultaneously.
The technical scheme providing according to the utility model, the automatic takeup of gig comprises gig housing, screw rod, stop nut, spring, setting nut and captive nut, pressing plate and driven subassembly; Described pressing plate covers on gig housing, driven subassembly is fixed on pressing plate, adapter plate passing on gig housing of screw rod, other end is connected with pressing plate by captive nut, spring is through on screw rod, adapter plate propping up on gig housing of described spring, other end is connected with screw rod with setting nut.
As further improvement of the utility model, on described screw rod, be provided with stop nut, described stop nut be screwed to and gig housing on adapter plate between distance be less than the position of 10 millimeters of amount of spring compression.
As further improvement of the utility model, described gig housing is provided with Long Circle adjustment hole, on described Long Circle adjustment hole, covers pressing plate.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, reasonable; By spring in addition tensioning can not produce excessive downforce to chain so that damage equipment, the lasting dynamics of spring has also been avoided needing manually often go to adjust simultaneously; It is both convenient to regulate like this, saves time not only but also laborsaving.Just can reflect intuitively in addition the elasticity of spring by the distance between the adapter plate on observation stop nut and gig housing.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure side view.
Detailed description of the invention
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, comprise gig housing 1, screw rod 2, stop nut 3, spring 4, setting nut 5 and captive nut 6, pressing plate 7 and driven subassembly 8; Gig housing 1 is provided with Long Circle adjustment hole, described Long Circle adjustment hole is covered by pressing plate 7, driven subassembly 8 is fixed on pressing plate 7,2 one adapter plates that pass on gig housing 1 of screw rod, other end is connected with pressing plate 7 by captive nut 6, spring 4 is through on screw rod 2,4 one adapter plates that prop up on gig housing 1 of described spring, and other end is connected with screw rod 2 with setting nut 5.
On described screw rod 2, be provided with stop nut 3, described stop nut 3 be screwed to and gig housing 1 on adapter plate between distance be less than the position of 10 millimeters of spring 4 amount of compressions.
Working process of the present utility model and principle of work
When gig promotes aggregate, driven unit drives driven subassembly to move together by plate chain or loop chain, therefore must ensure that plate chain or loop chain have certain degree of tension.Due to long-term operation, plate chain or loop chain can extend gradually or wear and tear, and cause chain to skid, therefore must be by addition tensioning of control apparatus.
In the time that driven subassembly need to regulate degree of tension, first upwards unclamp stop nut 3, then upwards tighten setting nut 5, thus holddown spring 4, now screw rod 2 with dynamic pressure plate 7 together with driven subassembly 8 to the object that is issued to tension chain.On described screw rod 2, be provided with stop nut 3, finally stop nut 3 is screwed to and gig housing 1 on adapter plate between distance be less than the position of 10 millimeters of spring 4 amount of compressions.Due to by spring in addition tensioning can not produce excessive downforce to chain so that damage equipment, the lasting dynamics of spring has also been avoided needing manually often go to adjust simultaneously.It is both convenient to regulate like this, saves time not only but also laborsaving.Just can reflect intuitively in addition the elasticity of spring by the distance between the adapter plate on observation stop nut 3 and gig housing 1.
