ANBIT YBE120.400P гидравлический обсадный домкрат для бурения скважин

The machinery is made of pulling equipment and electrohydraulic station. With the using of 7500 pulling cylinder for the pulling equipment and using of hydraulic cylinder of the slips, both clamping and disconnecting is quick and reliable. This machinery helps you to avoid the danger of manual operation and the efficiency has been greatly improved. The clamp is made of high alloy, both hardness and abrasion resistance have been increased after hardening. The reliability has been improved and the lifetime of clamp becomes longer.

The pulling equipment is made of upper board, upper hydraulic clamp, fasten base, down hydraulic clamp, slip, slip recess, pulling cylinder, and working station etc. The two cylinders are equipped between the upper board and fasten base. The slip recesses are placed on steering stem and fasten base.

The hydraulic station controlled by hydraulic pressure: manual pulling reversing valve, clamping reversing valve, high-pressure pipeline and pressure gauge etc.; As for the power part, it is consisting of electric motor, distribution box, high-pressure plunger oil pump, hydraulic oil tank, oil return filter, hydraulic oil cooler and frame etc..; The hydraulic station and the pulling equipment are connected quickly by a high-pressure hose through a special automatic sealing oil when working, forming a complete machine to achieve working requirements.

Power parameter: rated power of engine P=55kW

Rated Pressure p=31.5MPa

Working Parameter: rated pulling force F=200tonf(about 2000KN)

Max Lifting Value S=700mm 

Applicable tube diameter: Φ335-Φ400( according to your need)

Diameter of slip recess: about 430mm

Pulling equipment dimension: L750xW350xH920mm

Hydraulic station dimension: L 1500xW1100xH980mm

Weight: about 2200kg

Preparation: First, the hydraulic station and the extractor are connected by a high-pressure hose through a dedicated self-sealing oil quick connector and a puller. Start the motor for no-load operation for 3-5 minutes.

Lifting operation: Manipulating the clamping hydraulic valve, the upper clamping hydraulic cylinder pushes the upper slip to clamp the drill pipe, and at the same time, the lower slip is released, and the hydraulic valve handle is operated and pulled, and the pressure oil enters the lower chamber of the two extraction cylinders through the diverting joint. Push the upper board on the board and slowly pull the underground drill pipe out of the ground. After reaching the maximum stroke, loosen the upper slip and at the same time automatically clamp the lower slip to prevent the pulled rod from falling back. Then, the handle of the pull-out cylinder reversing valve is operated, so that the pressure oil enters the upper chamber of the two pull-out cylinders through the split joint, pushes the upper joint assembly back to the lower end, and after reaching the lower end, the hydraulic valve is clamped and clamped. The hydraulic cylinder pushes the upper slip to clamp the drill pipe, and at the same time, the lower slip is released, and the lifting cylinder is lifted. The above process is a work cycle. The work cycle is performed continuously,  thus the purpose of pulling long underground drill pipes out of the ground can be achieved.
