Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of tensioning apparatus of aggregate transporting machine, as depicted in figs. 1 and 2, including rack 1, one end of rack 1 are fixedly connected
Have actuator 2, can be motor, actuator 2 is sequentially connected with the drive roll 3 of cylinder roll, rack 1 far from drive roll 3 one
End is rotatably connected to rotating roller 4, has tightened conveyer belt 5 in drive roll 3 and rotating roller 4, when drive roll 3 rotates, 3 band of drive roll
Dynamic conveyer belt 5 moves.
It is fixedly connected to conditioning box 6 in the rack 1 at 4 both ends of rotating roller, limiting slot 7 is offered on the inner wall of conditioning box 6,
The cross section of limiting slot 7 is in arc-shaped.The both ends of rotating roller 4 are rotatably connected to bearing block 9 by self-aligning bearing 8, bearing block 9
Both ends have been wholely set limited block 10, and shape and the limiting slot 7 of limited block 10 match, and limited block 10 is slidably connected at limiting slot
In 7.
The cooperation of limiting slot 7 and limited block 10 so that bearing block 9 when being slided on conditioning box 6 by position-limiting action, be not easy
It is detached from conditioning box 6.Since the cross section of limiting slot 7 is in be connected between arc-shaped and adjusting block and rotating roller 4 by self-aligning bearing 8
It connects, therefore there are a degree of revolution spaces between bearing block 9 and conditioning box 6.When tensioning apparatus when used for a long time, limited block
It may be rusted between 10 and limiting slot 7, to generate gently between limiting slot 7 and limited block 10 by tapping bearing block 9 at this time
Micro- relative rotation, so that corroding being partially separated for bonding between limited block 10 and limiting slot 7.
The two sides of limiting slot 7 are fixedly connected to the abutting block 11 of rectangular strip, when 10 relative limit slot 7 of limited block slides
To when abutting block 11, is no longer rotated between bearing block 9 and conditioning box 6, avoid staff when tapping bearing, limiting slot
Relative rotation between 7 and limit hole is excessive to cause bearing block 9 and conditioning box 6 to be detached from.
The percussion piece 12 of disc-shaped is fixedly connected on bearing block 9, staff can tap when tapping bearing block 9 and strike
Hit on piece 12, make it is capable acted on bearing block 9 by tapping piece 12, therefore act on the power on bearing block 9 by an active force
Become face active force, reduces the loss to bearing block 9.
Nitrogen gas spring 13 and air pump 14 are provided on conditioning box 6, the nitrogen gas spring 13 includes inflatable article 15 and extensible member
16, the inflatable article 15 is fixedly connected on the conditioning box 6, and the extensible member 16 is slidably connected in the inflatable article 15,
The one end of extensible member 16 far from inflatable article 15 is fixedly connected with bearing block 9, and air pump 14 is fixedly connected in rack 1 and and inflatable article
15 connections, air pump 14 is used to control the air pressure in inflatable article 15, to control the elastic force of nitrogen gas spring 13.
When driving conveyer belt 5 to rotate, the tension that conveyer belt 5 is subject to can change drive roll 3 in certain section, work as transport
With 5 be subject to tension variation when, the relaxation degree of conveyer belt 5 can also change, and nitrogen gas spring 13 can then fill up the variation of tension,
So that the tensioning degree of conveyer belt 5 keeps stablizing, enable conveyer belt 5 tight always in rotating roller 4 and drive roll 3, reduces and beat
Sliding situation, so that conevying efficiency improves.
Be fixedly connected with multiple trunnion axis 17 in rack 1, trunnion axis 17 is horizontally disposed, and the length direction of trunnion axis 17 with
The length direction of conveyer belt 5 is vertical.Horizontal roller 18, the axle center of horizontal roller 18 and water are rotatably connected to by bearing on trunnion axis 17
Flat axis 17 is overlapped, and the surfaces of revolution of horizontal roller 18 contacts face of the conveyer belt 5 far from aggregate.Due to conveyer belt 5 transportation lengths compared with
Long, only both ends tensioning can not be tensioned conveyer belt 5 well, therefore install multiple horizontal rollers 18 in rack 1 and make conveyer belt 5
Conveyer belt 5 is held up during transportation, is sunk after avoiding conveyer belt 5 from being mounted with aggregate.
Frictional force due to being pivoting friction between conveyer belt 5 and horizontal roller 18, between conveyer belt 5 and horizontal roller 18
It reduces, is connected between horizontal roller 18 and trunnion axis 17 by bearing, therefore the frictional force between horizontal roller 18 and trunnion axis 17
It is smaller, the function that frictional force when conveyer belt 5 conveys aggregate is done is reduced, conevying efficiency is improved.
In conclusion when conveyer belt 5 convey aggregate when, conveyer belt 5 rotates under the drive of drive roll 3, conveyer belt 5 by
Tension can change in certain section, and nitrogen gas spring 13 can then fill up the variation of tension, and bearing block 9 is pushed to adjust
Sliding in frame 6, so that rotating roller 4 be tensioned conveyer belt 5 always, the tensioning degree of conveyer belt 5 keeps stablizing, thus conveyer belt 5 and
The case where skidding between drive roll 3 or rotating roller 4 is less, improves conevying efficiency.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
