Abstract
A trailer mounted power swivel includes, in combination, a trailer and a power swivel unit. The trailer is elongate and has ground engaging wheels supporting a cargo deck. The cargo deck is divided lengthwise into a first section and a second section. The power swivel unit is secured solely to the first section, thereby causing a load imbalance which renders the trailer unstable for highway travel. This imbalance can be remedied by placing the second section of the cargo deck under load. The second section of the cargo deck is adapted to carry a sufficient number of drill collars to counterbalance the weight of the power swivel unit until the stability of the trailer is restored.
Description
CA 0220667~ 1997-0~-29 TITLE OF THE lNv~NLlON:
trailer mounted power swivel NAME OF lN v~NlOR:
Warren Wessel FIELD OF THE lNv~NLlON
The present invention relates to a trailer mounted power swivel.
BACKGROUND OF THE lNv~NllON
Power swivel units used in the oil industry, along with associated drill collars, are transported from well site to well site. The equipment associated with the power swivel units along with the drill collars are sufficiently bulky that a large eighteen wheel truck and trailer unit must be used or a plurality of smaller transport vehicles.
SUMMARY OF THE lNv~N-LlON
What is required is a transport trailer capable of carrying all equipment associated with the power swivel and drill collars too.
According to the present invention there is provided a trailer mounted power swivel which includes, in combination, a trailer and a power swivel unit. The trailer is elongate and has ground engaging wheels supporting a cargo deck. The cargo deck is divided lengthwise into a first section and a second CA 0220667~ 1997-0~-29 section. The power swivel unit is secured solely to the first section, thereby causing a load imbalance which renders the trailer unstable for highway travel. This imbalance can be remedied by placing the second section of the cargo deck under load. The second section of the cargo deck is adapted to carry a sufficient number of drill collars to counterbalance the weight of the power swivel unit until the stability of the trailer is restored.
Mounting a power swivel unit onto a trailer, as described, is counterintuitive. With the power swivel unit mounted entirely on the first section of the cargo deck, the trailer is no longer road worthy. It is only when the second section of the cargo deck is loaded with drill collars that the stability of the trailer is restored. The trailer can be pulled by a 3/4 ton or one ton truck, which is a much more economical form of transport than has been used previously.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, wherein:
FIGURE 1 is a top plan view of a trailer mounted power swivel constructed in accordance with the teachings of the present invention.
FIGURE 2 is a side elevation view of the trailer mounted power swivel illustrated in FIGURE 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, a trailer mounted power swivel generally identified by reference numeral 10, will now be described with reference to FIGURES 1 and 2.
CA 0220667~ 1997-0~-29 Trailer mounted power swivel 10 includes, in combination, a trailer 12 and a power swivel unit generally identified by reference numeral 14. Trailer 12 has a tow hitch 16.
Referring to FIGURE 2, trailer 12 is elongate and has ground engaging wheels 18 which support a cargo deck 20. Referring to FIGURE 1, cargo deck 20 is divided lengthwise into a first section 22 and a second section 24. Power swivel unit 14 is positioned solely on first section 22. The preferred - embodiment of power swivel unit 14, as illustrated, includes the following components: primary motor 26, hydraulic reservoir 28, tool box 30, battery box 32, hydraulic pump 34, hydraulic reel motor 36, swivel head control panel 38, hydraulic reel control 40, power swivel head cradle 42, a first swivel head power hose reel 44, a second swivel head power hose reel 46, tool stub 48, power swivel head 50, hydraulic pull back winch 52, hydraulic torque assembly base 54, control panel stand 56, and hose rack 58. The combined weight of all of the components of power swivel unit 14 causes a load imbalance which renders trailer 12 unstable for highway travel until second section 24 of cargo deck 20 is under load. Second section of cargo deck 20 is adapted to carry a sufficient number of drill collars (not shown) to sufficiently counterbalance the weight of power swivel unit 14 until the stability of trailer 12 is restored.
It is preferred that a collar skid rail 60 and deflection plates 62 be used to protect swivel power unit 14 from sustaining damage during the loading and unloading of drill collars. It is also preferred that fold up stairs 64 be provided to facilitate access to power swivel unit 14 when working at a well site.
Trailer mounted swivel unit 10, as described, has proven able to transport power swivel unit 14, together with such drill collars as may be required. It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departlng from the spirit and scope of the invention as hereinafter defined in the Claims.
