Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making the creative labor
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-5, it is a kind of be used for inclined shaft belt feeder emergency shutdown when tension release device, include positioned at inclined shaft
Belt feeder, top and the counterweighted take-up 2 of the belt feeder coordinate, and lower part and the winch take-up device 1 of belt feeder coordinate.
The winch take-up device 1 includes guide rail bracket 9, the 4th bend pulley 10, sliding machine 11 and variable-frequency motor 12,
Guide rail bracket 9 and variable-frequency motor 12 are fixedly mounted, and guide rail bracket 9 is equipped with the sliding machine 11 of sliding, and sliding machine 11 passes through rope
Rope is connect with variable-frequency motor 12, and sliding machine 11 is equipped with the 4th bend pulley 10, and the return belt 3 of belt feeder changes around the 4th
To roller 10.
The side of the winch take-up device 1 is equipped with changed course holder 13, and the 5th changed course rolling is fixed on the holder 13 that alters course
Cylinder the 14, the 6th bend pulley 15 and the 7th bend pulley 16, the return belt 3 of belt feeder bypass successively the 5th bend pulley 14,
4th bend pulley 10, the 6th bend pulley 15 and the 7th bend pulley 16.
The counterweighted take-up 2 includes weight support 6 and weight 8, and the first bend pulley is fixed on weight support 6
4 and second bend pulley 5, the supporting leg of weight support 6 is equipped with the third bend pulley 7 of sliding, third bend pulley 7 and weight
The return belt 3 of 8 connections, belt feeder bypasses second bend pulley 5, third bend pulley 7 and the first bend pulley 4 successively.
The weight 8 is located in foundation pit, and weight support 6 is located at the top of foundation pit.
The utility model in upper fortune belt feeder in bottom of slope close to the position of tail bending roller, a set of frequency conversion is set and is twisted automatically
A set of counterweighted take-up is arranged close to the position of unloading roller at top of the slope in vehicle tensioning apparatus, which may be provided at foundation pit
It is interior, as shown in Figure 1.In fig. 2, return belt is carried out by the first bend pulley, third bend pulley and second bend pulley
Changed course, the first bend pulley and second bend pulley are each attached on weight support, and third bend pulley is constrained on weight branch
It on frame supporting leg, can slide up and down, weight is hung on third bend pulley.In Fig. 4, frequency conversion automatic winch tensioning apparatus has guide rail
Frame, the 4th tensioning bend pulley, sliding machine and variable-frequency motor composition, the 4th bend pulley are fixed on sliding machine, frequency conversion
Motor pulls sliding machine by steel wire rope, to complete the tension to belt.In Figure 5, frequency conversion automatic winch tensioning dress
The side set is equipped with changed course holder, since frequency conversion automatic winch tensioning apparatus cannot influence the normal operation of belt, it is therefore desirable to
It alters course to belt, belt moves to be tensioned filling to frequency conversion automatic winch under the action of the five, the 6th and seven bend pulleys
The equal place of seated position so that frequency conversion automatic winch tensioning apparatus plays a role.
In normal operation, the gravity of weight is more than the pulling force of belt, and belt pull is not enough to lift weight, weight
Tight device does not provide tensile force, and weight is located at lowermost end, and weight roller only plays the role of changed course, position as shown in Figure 2, by change
Frequency automatic takeup adjusting tensioning force of belt.When encountering emergency shutdown situation, for top of the slope since belt pull becomes larger, belt will
Weight is promoted, and position as shown in Figure 3, the belt distance of shortening will make up the flexible deformation of lower belt, and reduce the pulling force of lower belt,
Pulling force buffering is haved the function that.At bottom of slope, since the inertia of belt causes lower belt tension at bottom of slope to become smaller, frequency conversion is automatic
Automatic tension is avoided belt from accumulating by tensioning apparatus.When entire belt system tends towards stability, since weight gravity is more than belt
Pulling force, weight will drop at minimum point again again, meanwhile, belt pull is more than the drawing of variable frequency tensioning device setting at bottom of slope
Force value, belt are got back release, balance when entire belt system reaches static.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
