Abstract

The utility model discloses a steel strip tractor. A first roller and a second roller are movably supported on a frame, wherein the first roller is driven by a motor on the frame, the second roller and the first roller are arranged side by side, and the second roller close to the first roller is positioned above the back of the first roller. A third roller is arranged below the back of the first roller side by side, and two ends of the third roller are movably supported on the frame. By the aid of the steel strip tractor, both the contact area and the friction factor of a steel strip and the rollers can be increased effectively, interaction friction force can be further increased, and the increased friction force is capable of reliably drawing the steel strip to move forwards. The steel strip tractor is simple in structure, ingenious in conception and suitable for large-scale popularization and application.

Description

The steel band hauling machine

Technical field

The utility model relates to a kind of hauling machine that steel band moves forward that is used to spur.

Background technology

Traditional steel band hauling machine comprises frame; Movable supporting has the roll of two steels on this frame; These two rolls are arranged side by side up and down, and two rolls have a gear respectively, and this a pair of gear is meshed; One of them gear is meshed with gear on the motor output shaft, and this motor is installed on the said frame.When using the steel band hauling machine, let steel band pass two gaps between the roll earlier, restart motor, this moment, two rolls relatively rotated, and produce frictional force between steel band and the roll this moment, and this frictional force traction steel band moves forward.In use; We find because the contact area of steel band and roll is big inadequately, and frictional force between the two is not enough, usually can take place can not be normally to the situation of front haulage steel band; If think by force to the front haulage steel band; Generally can reduce the spacing of two rolls, and not only not reach the purpose that the traction steel band moves forward like this, but also can steel band be damaged by pressure.

The utility model content

The utility model technical problem to be solved is to provide a kind of can reliably draw the steel band hauling machine that steel band moves forward.

The technical scheme of the utility model is following: a kind of steel band hauling machine; Movable supporting has first and second roll on frame, and wherein first roll is by the driven by motor on the frame, and said second roll and first roll are arranged side by side; And near first roll; Its key is: said second roll is positioned at the back upper place of first roll, and is arranged side by side the 3rd roll in the back lower place of this first roll, and the two ends movable supporting of the 3rd roll is on said frame.

The utility model has changed the relative position of first and second roll on the basis of traditional structure, and second roll is located at the back upper place of first roll, is arranged side by side the 3rd roll in the back lower place of first roll in addition.When using this hauling machine traction steel band; After steel band passes the gap between first and second roll; Surround on the anterior periphery of first roll, extend back then, and surround on the periphery on the 3rd roll top; Periphery from the 3rd roll bottom extends forward at last, and steel band just forms serpentine between three rolls like this; This moment starter motor, the first roll generation rotation under the drive of motor, thus the traction steel band move forward.Adopt above technical scheme, the utility model can make the contact area of steel band and roll effectively increase, and then increases interactional frictional force, moves forward thereby can reliably draw steel band, and is simple in structure, is skillfully constructed, and is suitable for the large-scale promotion utilization.

The periphery of said first, second and third roll is equipped with rubber coating, and above structure can increase frictional force through increasing coefficient of friction on the one hand, can effectively avoid steel band is damaged by pressure again on the other hand.

Beneficial effect: the utility model can make the contact area of steel band and roll and coefficient of friction all effectively increase; And then increasing interactional frictional force, the frictional force of this increase can be drawn steel band reliably and moved forward, and is simple in structure; Be skillfully constructed, be suitable for the large-scale promotion utilization.

Description of drawings

Fig. 2 is the layout sketch map of first, second and third roll.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Like Fig. 1, shown in 2, the utility model is made up of frame 1, first roll 2, second roll 3, motor 4, the 3rd roll 5 and rubber coating 6, and its mid frame 1 is a prior art, does not do at this and gives unnecessary details.On above-mentioned frame 1, be arranged side by side three rolls, the two ends of each roll form the movable supporting relation with frame 1 respectively, and wherein first roll 2 is an existing structure, and second roll 3 is positioned at the back upper place of this first roll 2, and near first roll 2.In order to drive the work of this hauling machine, special motor 4 is set on frame 1, this motor 4 can drive 2 rotations of above-mentioned first roll,, does not give unnecessary details at this for having current techique now as for being connected of motor 4 and first roll 2, drive mechanism.Simultaneously, said the 3rd roll 5 is positioned at the back lower place of first roll 2.

As optimization, the periphery of said first roll 2, second roll 3 and the 3rd roll 5 is equipped with rubber coating 6.

When using this hauling machine traction steel band; After steel band 7 passes first and second roll 2, the gap between 3; Surround on the periphery of first roll, 2 front portions, extend back then, and surround on the periphery on the 3rd roll 5 tops; Periphery from the 3rd roll 5 bottoms extends forward at last, and steel band 7 just forms serpentine between three rolls like this.Under the drive of motor 4, rotation takes place in first roll 2, thereby traction steel band 7 moves forward.

The above is merely the preferred embodiment of the utility model; It is not restriction with the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
