Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drilling equipment, in particular, the present application relates to a steel pipe traction storage device. BACKGROUND

[0002] In the prior art, when the flexible steel pipe is used as the technical method for penetrating the stratum, the drum is used as the storage device of the flexible steel pipe, and the drum is used as the power source during penetration. However, in the process of penetration, the steel pipe needs to pass through the guide plate to enter the stratum. Since the power source of the flexible steel pipe penetration is at the end of the steel pipe, the front end is subjected to the resistance of the stratum and the reaction force of the straightening device, and the middle bending part will further bend uncontrollably. Therefore, the guide plate needs to be installed around the drum to enable the steel pipe to advance along the periphery of the drum, and finally be led out at the opening in the tangential direction. However, this will cause the steel pipe to rub against the guide plate and generate a strong reaction force, resulting in insufficient penetration power. When the steel pipe penetrates into a deeper stratum, the penetration resistance increases, the pressure between the steel pipe and the guide plate increases, and the friction force further increases, resulting in rapid loss of penetration power, and even the middle bending steel pipe is broken under the stress of forward and backward extrusion.

And the movable first friction chain 152 and the second friction chain 153 also provide a new operation idea, that is, when the operation space is limited, the steel pipe can be straightened in an inclined state, and the steel pipe is inserted in a diagonal direction, so as to have better operation adaptability. Since the steel pipe is in a bent state when it is stored, after it is transmitted out of the straightening mechanism in a vertical state, there may still be a certain residual bending stress, which causes the steel pipe to be not perpendicular when it is inserted into the stratum. By adjusting the horizontal distribution of the first friction chain 152 and the second friction chain 153 through the adjusting plate 12, the straightening degree of the flexible steel pipe 2 is changed, the flexible steel pipe 2 is further loaded in the opposite direction of the steel pipe storage bending, the residual bending stress is eliminated, and the probe rod instrument can be inserted into the stratum in a vertical state.

[0066] Optionally, the steel pipe traction storage device further comprises a first guide 141 and a second guide 142, the first guide 141 is fixed above the bearing frame 11 and opposite to the first steel pipe port, and the second guide 142 is arranged below the bearing frame 11 and opposite to the second steel pipe port. Wherein, the first guide 141 and the second guide 142 are provided with guide wheels on the side opposite to the flexible steel pipe 2.
