Abstract
The utility model application relates to a kind of Novel belt conveyor spiral tensioning device.Comprise the cylinder (2) be connected with belt (1), cylinder (2) is provided with the screw mandrel (3) driving cylinder (2) to move, and screw mandrel (3) is set in worm gear (4), establishes the internal thread coordinated with screw mandrel (3) in worm gear (4); Worm gear (4) is driven by worm screw (5), the driving mechanism that worm screw (5) peripheral hardware drives worm screw (5) to operate.The utility model has the advantages that: 1) the utility model utilizes the feature that worm gear transmission ratio is large, stable drive, noise are little, and therefore the utility model can adopt low-force square just can realize the tension of belt; 2) the utility model is equipped with screw rod transmission, utilizes screw rod transmission feature accurately, realizes the accurate tension of belt; 3) the utility model adopts worm gear structure, therefore rotating nut can be arranged on frame lower, facilitate the operation of personnel, and can not affect the layout of conveyer.
Description
Technical field
The utility model application relates to mineral ribbon conveyer, is a kind of spiral tensioning device of belt conveyor.
Background technology
Ribbon conveyer is a kind of conveying equipment of the field extensive uses such as modern cement, coal, harbour and mine, has that structure is simple, lightweight, conveying capacity is large, the advantages such as fed distance is long, and freight is low, and Operation and Maintenance is simple!
After a certain period of use time, due to the effect of tension force, belt there will be certain lax ribbon conveyer, there will be the phenomenons such as skidding thus affects the work of conveyer, thus can design a kind of spiral tensioning device.By adjustable screw take-up device, make belt keep tensioning state, thus make conveyer even running.
But some spiral tensioning devices now, because screw mandrel length is longer, and general by the rotary head with spanner rotary screw rod end, drive working position move a certain distance thus play the effect of tensioning.This kind of project organization is simple, but comes with some shortcomings, and because the length of screw mandrel is longer, the distance in stress point and motor point is longer, needs larger moment, and screw mandrel can be made in actual use procedure to occur bending and deformation, and reduces its service life! In addition because stress point and motor point are apart from oversize, add that conveyer site layout project is generally compact, human users can be a great inconvenience.
Utility model content
The utility model object is the problem proposed in technical solution background, provides that a kind of structure is simple, the spiral tensioning device of belt conveyor of superior performance.
The technical solution adopted in the utility model is for this reason: the utility model comprises the cylinder (2) be connected with belt (1), cylinder (2) is provided with the screw mandrel (3) driving cylinder (2) to move, screw mandrel (3) is set in worm gear (4), establishes the internal thread coordinated with screw mandrel (3) in worm gear (4); Worm gear (4) is driven by worm screw (5), the driving mechanism that worm screw (5) peripheral hardware drives worm screw (5) to operate.
The rotating nut (6) that described driving mechanism is and worm screw (5) coordinates, rotating nut (6) is pulled by spanner.
Described cylinder (2) is connected with screw mandrel (3) by slide block (7).
The utility model has the advantages that: 1) the utility model utilizes the feature that worm gear transmission ratio is large, stable drive, noise are little, and therefore the utility model can adopt low-force square just can realize the tension of belt; 2) the utility model is equipped with screw rod transmission, utilizes screw rod transmission feature accurately, realizes the accurate tension of belt; 3) the utility model adopts worm gear structure, therefore rotating nut can be arranged on frame lower, facilitate the operation of personnel, and can not affect the layout of conveyer; 4) worm and gear and screw mandrel combine by the utility model, can realize the spiral fastening of belt, can protect two transmission mechanisms again, make it have good service life.

Fig. 2 is I enlarged drawing in Fig. 1.
Fig. 3 is the side view of Fig. 2.
Fig. 4 is the structural representation of prior art take-up device.
1 be belt, 2 be cylinder in figure, 3 be screw mandrel, 4 be worm gear, 5 be worm screw, 6 be rotating nut, 7 for slide block.
Detailed description of the invention
The utility model comprises the cylinder 2 be connected with belt 1, and cylinder 2 is provided with the screw mandrel 3 driving cylinder 2 to move, and screw mandrel 3 is set in worm gear 4, establishes the internal thread coordinated with screw mandrel 3 in worm gear 4; Worm gear 4 is driven by worm screw 5, the driving mechanism that worm screw 5 peripheral hardware drives worm screw 5 to operate.
Described driving mechanism is the rotating nut 6 coordinated with worm screw 5, and rotating nut 6 is pulled by spanner.
Described cylinder 2 is connected with screw mandrel 3 by slide block 7.
This take-up device operation principle is as follows:
The utility model is by rotating the rotating nut 6 on spiral lifting mechanism with spanner, thus drive worm screw 5 to rotate, worm screw 5 drives worm gear 4 to rotate again, the internal thread matched with screw mandrel 3 established by worm gear 4, be threaded connection and drive screw mandrel 3 to move, thus drive whole cylinder 2 to move by slide block 7, play the effect of tightening belt 1.
Rotating nut 6 of the present utility model can substitute by the frame for movement that other have similar functions.
