Abstract
The utility model relates to a tension device for a belt conveyer. The utility model has the structure that an upper guide beam, a lower guide beam and a bracket are welded to form an integral tension device rack provided with a tail bend pulley, a screw, a nut, a spring, a sliding sleeve, a sliding rack, an alarm bell and a switch; a tension stroke of the utility model is composed of a spiral main stroke and a spring subsidiary stroke. The utility model has the characteristics of simple structure, convenient installation and easy adjustment, and the tension force can be automatically kept within an operation range.
Description
The utility model is a kind of take-up device of belt conveyer, and it can keep the size of load-transfer device tightening force within the specific limits automatically.
At present, the take-up device of known belt conveyer generally has three kinds: spiral tensioning device, vertical tensioning device and Che Shi take-up device.Wherein, spiral tensioning device has tension travel limited, and tightening force can not keep, be suitable for shortcomings such as the conveyer captain is short automatically; Vertical tensioning device has shortcomings such as complex structure, inconvenience are adjusted, load-transfer device is fragile; Car formula take-up device has the increase floor area, is applicable to the shortcomings such as conveyer that the captain is big, operational throughput is big.
The purpose of this utility model is realized by following structure: go up guide beams 7 and two following guide beams 9 and two supports 10 by two that be arranged in parallel and be welded into a take-up device frame integral body.Have can be along the balladeur train 15 of its slip for guide beam 7 on two, above the balladeur train 15 with afterbody changed course cylinder 5 bearing seats 6 with Bolt Connection together, be connected with the sliding sleeve 13 that can slide along screw rod 8 below the balladeur train 15.Two screw rods that are parallel to each other 8 are installed between the upper and lower guide beam, and screw rod 8 two ends connect with support 10 usefulness half block formula fixed plates 11; Screw rod 8 is through in the sliding sleeve 13, and screw rod 8 is provided with the nut 1 with pressure stop collar 3 solder togethers.Processedly below the cylindrical of nut 1 fall a part, go into a plane breach with thread center's line parallel, the breach face is positioned at down on the guide beam 9.Spring 2 is positioned on pressure stop collar 3 inner screws 8, and an end is pressed on the nut 1, and the other end is pressed on the sliding sleeve 13.The not enough alarm switch 12 of one cover predetermincd tension is installed on nut 1 and the sliding sleeve 13.And be connected with alarm bell 14 on being installed in balladeur train 15.As shown in drawings.
Principle of work of the present utility model is:
During adjusting screw(rod) 8,, can only move along screw rod 8 because guide beam 9 stops and can not rotate under nut 1 quilt.Move compression spring 2 when adjusting screw(rod) 8 makes nut 1, contact with sliding sleeve 13 up to pressure stop collar 3, load-transfer device 4 is in maximum functional tightening force state.Along with load-transfer device 4 elongation gradually in use, move behind the afterbody changed course cylinder 5, make spring 2 elongations, tightening force descends thereupon.When dropping to minimum work tightening force, tightening force is not enough, and alarm switch 12 is connected, and alarm bell 14 is rung and given a warning.Readjust screw rod 8 and be in maximum functional tightening force state to load-transfer device 4.So repeatedly, realize the limited quantitative automatic adjusting of load-transfer device 4 tightening forces.Adjustment travel is made up of two parts: a part is according to the percentage elongation of load-transfer device 4 and complete machine length and design-calculated nut 1 stroke, and it is main stroke; Another part is spring 2 strokes that keep the tightening force size automatically, and it is auxilliary stroke.Like this, can satisfy conveyer, can make load-transfer device remain on the predetermincd tension state work down of normal need all the time automatically again the long-term needs of load-transfer device tightening force at whole stroke.
The utility model has the advantages that:
1, tightening force can keep in certain stroke and time range automatically, has overcome the shortcoming that the spiral tensioning device tightening force frequently and is blindly regulated, and makes adjustment more accurately and reliably.
2, owing to do not have vertical tensioning device frame and three changed course cylinders of that cover of vertical tensioning device, easy for installation so the utility model is simple in structure, it is easy to adjust, and accident potential reduces, and serviceability increases, and the load-transfer device life-span prolongs.
3, can be according to length, the bandwidth of conveyer, concrete operating mode such as exert oneself needs, the different springs of parameter such as design alternative steel wire diameter, middle footpath, pitch, lift angle to tightening force.
Embodiment:
In conjunction with the accompanying drawings, the utility model is specifically implemented as follows:
When rotating screw bolt 8, nut 1 is stopped by guide beam 9 down can only do moving of compression spring 2, and the sliding sleeve 13 that spring 2 promotes to link to each other with afterbody changed course cylinder 5 moves, thereby realizes the tension of load-transfer device 4 is moved.
During installation, nut 1 is adjusted to screw rod 8 tops, and tension load-transfer device 4 makes spring 2 be compressed to minimum permission control position, and pressure stop collar 3 contacts with sliding sleeve 13, loosens load-transfer device 4 after the sulfuration of load-transfer device 4 joints is bonding.Adjusting screw(rod) 8 moves nut 1, and compression spring 2 contacts with sliding sleeve 13 up to pressure stop collar 3, and spring 2 is in the maximum working pressure (MWP) position, and load-transfer device 4 also is in maximum tightening force state, shown in location status above in the accompanying drawing.
In the work, along with load-transfer device 4 elongation gradually in use, move behind the changed course cylinder 5, spring 2 extends gradually, and the tightening force of load-transfer device 4 descends thereupon.When load-transfer device 4 tightening forces dropped to required minimum value, tightening force is not enough, and alarm switch 12 was connected, alarm bell 14 warning of ringing.Shown in lower position state in the accompanying drawing.Regulate two screw rods 8 once more and make nut 1 compression spring 2 to the maximum working pressure (MWP) position, load-transfer device 4 is in maximum functional tightening force state again.So repeatedly, realize the automatically regulating of tension travel.
Claims (3)
1, a kind of take-up device of belt conveyer is characterized in that: it is gone up guide beams 7 and two following guide beams 9 and two supports 11 by two that be arranged in parallel and is welded into a take-up device frame integral body jointly; Two balladeur trains 15 are housed on guide beam on two 7, are in the same place with afterbody changed course cylinder 5 bearing seats 6 usefulness Bolt Connection above the balladeur train 15, be connected with sliding sleeve 13 below; Two screw rods 8 that between last guide beam 7 and following guide beam 9, have been arranged in parallel equally, screw rod 8 is positioned at sliding sleeve 13, also is provided with nut 1, pressure stop collar 3 and spring 2 above, and two ends are fixed with support 10 usefulness Bolt Connection by two half block formula fixed plates 11 respectively; Nut 1 and pressure stop collar 3 weld togethers; Spring 2 one ends contact with nut 1, and an end contacts with sliding sleeve 13.
