3C1-98 XYQ3C.Z 1.5 main clamp front plate holder Drill pipe power tongs

DQ178/40Y-TB multi-purpose hydraulic power tongs are used for loading and unloading 2 7/8″～4″ drill pipe, 2 7/8″～41/2″ tubing and 4 1/2″ in oil field drilling and workover operations. An open-ended power tong with ~7″ casing.

This product has the following features:

1. The complete set of power tongs is composed of main tongs and hydraulic back tongs. The main and back tongs can be clamped separately, and the movements are coordinated and flexible.

2. The pliers of the main pliers and the back pliers all use the inner curved roller to climb the slope, and the two-way clamping mechanism clamps the pipe string, the coupling or the joint. The structure is simple and the work is reliable.

3. The combination of the main and back clamps is a steel bracket structure, the upper and lower clamps are integrated, and the connection displacement of the main and back clamps is reliable when clamping the pipe string.

4. The caliper head adopts the brake band braking method, the braking torque is large, the operation is simple, and it is easy to adjust and replace.

5. The shell is made of low-alloy manganese steel plate, which increases the overall rigidity of the power tong. The jaw plates, tooth seats and gears of various specifications are made of alloy steel forgings, and are processed by heat treatment to ensure that the power tong has the highest torque at the maximum torque. enough strength.

6. The main and back clamp reset knobs are designed as reset handles, which are flexible in operation and easy and safe to reset.

7. The clamping coupling of the back clamp adopts the clamping liquid cylinder to push the plate action device, and the clamping is reliable.

8. Hydraulic system control adopts hydraulic valve group to ensure the reliable action of the back clamp, adjust the oil supply pressure, and obtain the best torque required when various steel grade pipe strings are made up.

9. The lengthened guide rod is adopted, and the back clamp can clamp the coupling or joint as well as the pipe body.

10. The front and rear displacements of the combined tongs are driven by transfer cylinders for users to choose and use. The operation is easy, labor intensity is reduced, labor-saving and safe.

11. The main tong is equipped with a safety door and a hydraulic valve group self-locking linkage device. When the safety door is in the open position, the handle of the manual reversing valve of the power tong is in the locked position, which is convenient and safe to operate (this device is a patent developed by our company, patent number: ZL 2008 2 0160143.9).

12. The whole machine is equipped with a hydraulic torque indicating instrument, and has a torque meter installation interface and a lap measurement interface for users to choose and use, which is convenient for computer management.
