Abstract

The utility model discloses an extension machine tube-drawing device. The utility model comprises a rack, an upper roller screw-down device, a lower roller device, a swing arm, a motor reducer and a cylinder. The upper roller screw-down device is movable connected with the rack. The middle of the swing arm is articulated with the rack. The lower roller device is connected with the upper end of the swing arm through a bearing. One end of the lower roller device is connected with the motor reducer. Two ends of the cylinder are respectively articulated with the lower ends of the rack and swing arm. The tube drawing device of the utility model has good rigidity, big torque, simple operation and high safety performance, and the steep pipe can be quickly drawn out from the extension device.

Description

The elongator pipe drawing device

(1) technical field

The utility model relates to a kind of elongator auxiliary device of rolled steel tube, particularly a kind of elongator pipe drawing device.

(2) background technology

At present, elongator does not go out pipe owing to what the reason of each side caused in the rolled steel tube process, remain manually will manage rotation and extract with pipe wrench, because tube temperature is very high, and the danger close that operates, difficultly, people's labour intensity is also very big.

(3) summary of the invention

The technical problems to be solved in the utility model is: a kind of mechanokinetic elongator pipe drawing device is provided, makes it can replace manually pipe being extracted.

In order to solve the problems of the technologies described above, the utility model comprises support body, top roll screwdown gear, following roller arrangement, swing arm, motor reducer and oil cylinder, top roll screwdown gear and support body flexibly connect, the swing arm middle part is hinged with support body, following roller arrangement is connected with the upper end of swing arm by bearing, following roller arrangement one end is connecting motor reducer, and the two ends of oil cylinder are hinged on the lower end of support body and swing arm respectively.

For the ease of transmitting moment of torsion, described roller arrangement down is connected by universal drive shaft with motor reducer.

Regulate the height of top roll screwdown gear for convenience, described top roll screwdown gear is arranged on the support body by the leading screw screw, screw is fixed on the top of top roll screwdown gear, leading screw is rotating to be fixed on the support body, the top of leading screw is fixed with handwheel, nut sleeve is slidingly connected by two axial feather keys and support body on the screw outer wall on leading screw.

The beneficial effects of the utility model are: the utility model pipe drawing device good rigidly, torsion is big, and is simple to operate, safe, can fast steel pipe be extracted from elongator.

Fig. 2 is Fig. 1 left side TV structure schematic diagram.

Wherein: 1, support body, 2, the top roll screwdown gear, 3, roller arrangement down, 4, oil cylinder, 5, motor reducer, 6, universal drive shaft, 7, swing arm.

(5) specific embodiment

Be a kind of specific embodiment as shown in Figure 1 and Figure 2, comprise support body 1, top roll screwdown gear 2, roller arrangement 3, oil cylinder 4, motor reducer 5, universal drive shaft 6 and swing arm 7 down.

Top roll screwdown gear 2 is arranged on the support body 1 by the leading screw screw, screw is fixed on the top of top roll screwdown gear 2, and leading screw is rotating to be fixed on the support body 1, and the top of leading screw is fixed with handwheel, nut sleeve is connected with support body 2 by two axial feather keys on the screw outer wall on leading screw.

Swing arm 7 middle parts and support body 1 are hinged, following roller arrangement 3 is connected by the upper end of bearing with swing arm 7, and bearing adopts taper roll bearing, and following roller arrangement 3 one ends are connecting motor reducer 5 by universal drive shaft 6, the lower end of oil cylinder 4 is hinged on the support body 1, and the lower end of the upper end of oil cylinder 4 and swing arm 7 is hinged.

The roller of roller arrangement 3 was all felt relieved with taper roll bearing under top roll screwdown gear 2 reached, and can bear very big axial force and radial load, and resistance was very little.

Following roller arrangement 3 is a drive roll, and its huge moment of torsion comes from motor reducer 5 and transmits by universal drive shaft 6, and the upwards swing of following roller arrangement 3 realizes by oil cylinder 4.During action, oil cylinder 4 starts simultaneously with motor, oil cylinder 4 runs to certain position and stops to be in packing state, motor reducer 5 drives down, and roller arrangement 3 continues rotation, at this moment, the adjusting handle that rotates top roll screwdown gear 2 makes top roll screwdown gear 2 contact with steel pipe, and steel pipe produces steel pipe by the moment of torsion that descends roller arrangement 3 under the clamping of top roll screwdown gear 2 and following roller arrangement 3.
