Problems solved by technology

[0003] Positioning two large diameter pipes (such as oilfield pipes) for butt jointing is very time consuming and can take many hours and require a lot of manpower and millions of dollars worth of equipment which is very expensive and slows down the production of the pipes
In addition, the current process is dangerous for workers

Embodiment Construction

[0046] see Figure 1-3 , shows that the connecting device 10 is configured to align the ends of the pipes during the butting process of the pipes. The connection device 10 is mounted to the arm of a construction equipment (not shown). The attachment device 10 includes a main beam 14 pivotably connected to the base of a lower head assembly 16 by a pivot 18 . The lower head assembly 16 is rotatably connected to the mounting bracket 20 to allow the lower head assembly 16 to rotate or rotate 360 ​​degrees about a vertical axis relative to the mounting bracket. Mounting bracket 20 removably mounts the attachment device to the arm of the construction equipment. Tilt actuators (drives) 22 , 24 extend between the lower head assembly 16 and the main beam 14 for selectively tilting the main beam about the pivot 18 . Further information on the construction and operation of the main beam, lower head assembly, mounting bracket and tilt actuator (driver) can be found in US2009 / 0057019 an...

Abstract

The invention discloses a connection device arranged for connection to an arm of a construction equipment. The connecting device includes a pair of grapple mechanisms mounted on the main girder. Each grapple mechanism includes opposing grapple arms mounted to the grapple housing. The grapple arm housings of the grapple mechanism are each independently adjustable relative to the main beam in one or more directions generally perpendicular to the longitudinal axis of the main beam. The connecting means allows for fine adjustment of the position of the tube ends relative to each other until the ends are aligned with each other, at which point the tube ends can be welded or otherwise secured to each other while being held in place by the grab mechanism.

Description

[0001] This application claims priority to U.S. Provisional Application Serial No. 61 / 599,164, filed February 15, 2012, and U.S. Provisional Application Serial No. 61 / 443,737, filed February 17, 2011, and both applications The entire contents are hereby incorporated by reference. technical field [0002] The present invention relates to a (joining) device connectable to eg a crawler, backhoe, excavator or other construction equipment for eg positioning pipe ends for joining them together. Background technique [0003] Positioning two large diameter pipes, such as oilfield pipes, for butt-jointing is very time consuming and can take many hours and requires a lot of manpower and millions of dollars worth of equipment, which is very expensive and slows down the production of the pipes. Furthermore, the current process is dangerous for workers. Any reduction in the time and cost required to make a docking connection is beneficial. Additionally, increased safety for ground work...
