Summary of the invention
The utility model purpose provides a kind of stretching device of chain converyer, and is easy to adjust, synchronous by the improvement of structure, occupies little space, and do not have potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is: a kind of stretching device of chain converyer, comprise the bearing that is fixed on chain converyer girder below, be fixedly arranged on transition wheels on this bearing, be slidedly arranged on two of girder below and adjust wheels, described transition wheels are made of the transition wheel that is fixedly arranged on the transition wheel shaft on the bearing and be sheathed on this transition wheel shaft, and each described adjustment wheels is made of the adjustment wheel seat that is slidedly arranged on the girder below, the regulating wheel that is connected on this adjustment wheel seat;
Described transition wheels, two regulating wheels form the del setting, and the axis of described transition wheel is parallel with the axis of two regulating wheels, and described chain is wound in wherein on a regulating wheel, transition wheel, another regulating wheel successively;
A close wherein position of adjusting wheel seat is provided with the adjusting screw(rod) that is spirally connected with bearing on the described bearing, and the end of described adjustment screw rod presses on to be adjusted on the wheel seat.
In the technique scheme, be equipped with an adjusting screw(rod) that is spirally connected with bearing near two positions of adjusting wheel seats on the described bearing.
In the technique scheme, two described regulating wheels form the below that yi word pattern relatively is slidedly arranged on girder.
In the technique scheme, the lower surface of described girder is provided with the T slot of penetrating length direction, and described adjustment wheel seat is the U-shaped structure of half-twist, and its both wings outside face is provided with chute, respectively with girder on consist of described T slot two hook pin consist of sliding block joint.
Further technical scheme, described regulating wheel are utilized bolt to be fixed in and are adjusted on the wheel seat.
The utility model principle of work: the end of adjusting screw rod presses on to be adjusted on the wheel seat, by adjusting the position of screw rod, and to regulate two spacings of adjusting between the wheels, when spacing is turned down, chain tension; When spacing was tuned up, chain loosened.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the position of adjustment wheels of the present utility model on the girder length direction is adjustable, and utilizes the adjusting screw(rod) location after adjusting, when two adjustment wheels spacings are turned down, and chain tension; When two adjustment wheels spacings tuned up, chain loosens, and was easy to adjust, synchronous.
2. each structure of the present utility model is located at chain converyer girder below, occupies little space, and does not have potential safety hazard.
