Detailed Description
The dual-purpose roller of the workover rig comprises a left bearing seat 1, a right bearing seat 2, a push disc clutch 4, a driving sprocket 7, a brake hub 8, a driving shaft 6 and a roller main body 3 (see figure 1 of the specification).
A roller main body 3 is arranged between the left bearing seat 1 and the right bearing seat 2 which are symmetrically arranged. A push disc clutch 4 is arranged on one side of the right bearing seat 2. The push-disc clutch 4 is an existing device that is outsourced.
The drum body 3 includes an inner drum 9, a rope groove plate 10, a sleeve 11, an end plate 12, a side plate 14, and a coupling plate 13 (see fig. 3 of the specification).
The rope groove plate 10 is attached to the circumferential surface of the inner roller 9 by screws. The rope groove plate 10 is an arc plate; rope grooves are uniformly distributed on the surface of the rope groove plate 10 (see figure 3 of the specification). The purpose of the rope groove plate 10 is thus to: so that the rope groove plate 10 can be quickly mounted on the circumferential surface of the inner roller 9 by means of screws or removed from the circumferential surface of the inner roller 9 in operation.
The inner rollers 9 at the two ends of the rope groove plate 10 are fixedly provided with shaft sleeves 11; the outer end of the shaft sleeve 11 extends to the outer side of the inner roller 9 and is fixedly provided with an end plate 12; the inside of the sleeve 11 is fitted with a coupling plate 13 and a side plate 14 in sequence. A plurality of reinforcing plates 15 are connected between the link plate 13 and the end plate 12. The purpose of providing the side plates 14 and the reinforcing plates 15 is to: so as to enhance the connection strength between the connecting plate 13 and the end plate 12 and the shaft sleeve 11 and the inner roller 9, and avoid the problem that the connecting plate 13 and the end plate 12 are easy to deform after being stressed.
The connecting plate 13 is fixedly provided with a brake hub 8. The end plate 12 is fixedly connected with the corresponding support plate 5. The two ends of the roller body 3 are fixedly provided with supporting plates 5 (see figure 1 of the specification) through bolts. The middle part of the supporting disc 5 is provided with a supporting sleeve 16; the circumferential surface of the support plate 5 is provided with a plurality of fitting holes 17 (see fig. 5 of the specification); the support plate 5 is connected to the drum body 3 through the assembly holes 17 and bolts. A keyway 18 (see fig. 5 of the specification) is provided in the support sleeve 16.
The center of the roller main body 3 is provided with a transmission shaft 6; one end of the transmission shaft 6 passes through the supporting disc 5 and then is connected with the left bearing seat 1; the other end of the transmission shaft 6 sequentially passes through the supporting disc 5 and the right bearing seat 2 and then is connected with the push disc clutch 4. The drive shaft 6 is connected to the support sleeve 16 by means of a key way 18 and a flat key. So when the transmission shaft 6 rotates, the supporting disc 5 drives the roller main body 3 to synchronously rotate.
A transmission chain wheel 7 is arranged on a transmission shaft 6 between the right bearing seat 2 and the push disc clutch 4 through a bearing; the drive sprocket 7 is connected with the push disc clutch 4.
The dual-purpose roller of the workover rig can drive the driving sprocket 7 to rotate through a chain when the power mechanism of the workover rig works, and the driving sprocket 7 can transmit power to the transmission shaft 6 through the push disc clutch 4 in the rotating process of the driving sprocket 7 and drive the transmission shaft 6 to synchronously rotate. In the rotation process of the transmission shaft 6, the roller main body 3 can be driven to synchronously rotate. The well repair operation can be completed in the rotation process of the roller main body 3. When the pumping operation is required, the rope groove plate 10 is disassembled.
The dual-purpose roller of the workover rig is compact in structure and ingenious in design, well workover operation can be completed by installing the rope groove plate 10, swabbing operation can be performed when the rope groove plate 10 is disassembled, and therefore the problems that occupied space is large and chassis load is heavy when the conventional workover rig needs to use double rollers to complete well workover and swabbing operation are solved, and the dual-purpose roller is particularly suitable for use requirements of the workover rig.
