Description

[0001] TENSIONER TRANSPORT APPARATUS [0002]

One embodiment of the present invention relates to a tensioner moving device capable of moving a tensioner in a simple configuration when a positional movement of the tensioner is required at drilling positions.

Generally, a tensioner is installed in a well to install a pipe for transferring the product generated during the drilling operation to the land or the processing position.

Such a tensioner may be required to change the installed position in order to carry out work such as a pipe line end terminal during a drilling operation.

Thus, changing the position of the tensioner changes the position of the tensioner using a multi-joint cylinder. That is, the tensioner may be connected to the rod of the multi-joint cylinder, and the position of the tensioner may be changed according to the forward or backward movement of the rod.

However, changing the position of the tensioner using a multi-joint cylinder has a problem in that the work of changing the position of the tensioner is complicated and the maintenance cost is excessively high.

It is an object of the present invention to provide a tensioner moving device capable of reducing the time and cost required for changing the position of a tensioner during a drilling operation.

An embodiment of the present invention provides a railway vehicle comprising a guide frame installed at a position spaced apart from a side surface of a tensioner for installing a pipe for drilling in a well, a rack gear installed on a guide frame and extending to both sides with a tensioner interposed therebetween, A pinion gear meshed with the rack gear, and a driving portion provided in the tensioner and providing a rotational driving force to the pinion gear.

The guide frame may be provided with a moving guider for guiding the movement of the tensioner.

The moving guider may include a guide rail provided on the guide frame, and a guide roller installed on the roller frame protruding from the tensioner and rotated in a state of being in contact with the guide rail.

The driving portion may be a driving motor in which the body portion is installed in the tensioner and the rotating shaft is connected to transmit rotational force to the pinion gear.

The rack gears may be provided on the upper side surface and the lower side surface opposite to the upper side surface, respectively, along the longitudinal direction of the guide frame.

According to an embodiment of the present invention, the position change of the tensioner can be changed by driving the rack gear and the pinion gear so that the position changing process of the tensioner is performed quickly, the time required for the operation is shortened, Can be saved.

1 to 4, a tensioner moving apparatus 100 according to a first embodiment of the present invention includes a tensioner 15 disposed at a position spaced apart from a side surface of a tensioner 15 for installing a pipe for drilling in a well 13, A rack gear 20 which is installed on the guide frame 10 and extends to both sides with the tensioner 15 interposed therebetween and a pinion gear 20 which is engaged with the rack gear 20 And a driving unit 40 installed in the tensioner 15 and providing a rotational driving force to the pinion gear 30.

The tensioner 15 described below is for installing a pipe through which a drilling material such as gas generated in the course of a drilling operation moves in the well. Such a tensioner 15 may need to be repositioned during the operation of the pipeline. Therefore, the guide frame 10 for moving the tensioner 15 is installed along the installed position of the tensioner 15.

The guide frame 10 is installed to move the tensioner 15 and is extended in a predetermined length from the position where the tensioner 15 is installed to a position spaced a predetermined distance above the drilling operation position Respectively. In this guide frame 10, a rack gear 20 is provided.

The rack gear 20 is installed in the guide frame 10 and extends along the longitudinal direction of the guide frame 10. The rack gear 20 may have a length corresponding to the movement position of the tensioner 15 with the tensioner 15 interposed therebetween. The rack gear 20 may be installed on the upper and lower sides of the guide frame 10, respectively. The pinion gear 30 is engaged with the rack gear 20.

The pinion gear 30 is meshed with the rack gear 20 and is rotationally driven by receiving the driving force of the driving part 40. Although the pinion gear 30 is shown as being provided with one pinion gear 30 corresponding to one rack gear 20 in the figure, At least two rack gears 20 may be provided. The rotation shaft of the pinion gear 30 is rotated by receiving the driving force of the driving unit 40. When it is determined that the positioner of the tensioner 15 needs to be moved, the driving shaft 40 is driven to rotate.

As described above, the driving unit 40 is selectively driven when it is determined that the positioner of the tensioner 15 needs to be moved. In this embodiment, the body of the driving unit 40 may be integrally connected to the tensioner 15, and the driving shaft may be installed as a driving motor connected to transmit the driving force to the pinion gear 30. Hereinafter, the driving unit and the driving motor use the same reference numeral 40.

Thus, when the drive unit 40 is driven, the pinion gear 30 and the rack gear 20 are engaged with each other. Here, the rack gear 20 is fixed to the guide frame 10, and the tensioner 15 is installed so as to be movable a certain distance from the drilling operation position. Therefore, when the driving operation of the driving motor 40 is performed, the tensioner 15 can be easily moved to the position to be moved according to the coupling drive of the rack gear 20 and the pinion gear 30.

The tensioner moving device 100 according to the first embodiment of the present invention is provided with the rack gear 20 along the longitudinal direction of the position at which the tensioner 15 is intended to move and the pinion gear 30 It is possible to easily change the position of the tensioner 15 by the drive force of the drive motor 40 by providing the tensioner 15 with the drive motor 40 for transmitting the rotational force.
