ADJUSTABLE BLADE AND CARRYING lVIEANS This invention relates to a levelling attachment for the rear of a truck having a drill thereon whereby the truck may be used to level drill sites and to carry extra equipment to and from drill sites. More particularly the invention relates to a substructure, blade supports, blade, and blade control means for use with a truck with drilling equipment thereon.
In oil well drilling it is preferable to have a shallow surface hole completed before an oil drilling rig is moved onto the drill site. The first thirty feet of ground is usually not well consolidated and it is desirable to drill a hole through this ground and to set a surface casing in this hole to prevent erosion of the ground by drilling mud circulated at high pressure during drilling operations with a conventional drilling rig. A truck with drilling equipment thereon is used to drill these surface holes. In drilling these holes drilling chips are brought to the surface and pushed to either side. However before an oil rig can be moved into drilling position it is necessary to level the site around the surface hole.
In order to level the drilling site after the surface hole has been completed it has been the practice to bring a tractor into the drill site where possible or in the alternative to bring in wheel barrows on the drilling truck. It is time consuming and difficult to remove drill chips by wheel barrow and to leave a level site. It is costly to move in a tractor simply to perform the removing of chips and levelling of the drill site when it is recalled that drill sites are often in generally uninhabited areas.
In order to overcome the above-noted difficulties the applicant has modified a drill truck having a drill thereon to provide a clearing and levelling capacity and as well to provide a greater transporting capacity for the truck.
In the drawings which form part of this specification like numbers represent the same element in the various figures.
FIG. 1 is a perspective view of the rear of a tandem truck with a drill thereon showing the attachment in its carrying capacity.
FIG. 2 is a rear view of the substructure added to the truck.
FIG. 3 is a side elevation view of the truck frame, substructure and blade support.
FIG. 4 is a plan view of the blade of the attachment.
FIG. 5 is an elevation view of the blade.
Referring to FIG. 1 the truck 1 has a drill 2 thereon and an attachment 3 for clearing, levelling and transporting attached to the truck 1. The attachment 3 is comprised of a substructure 4, blade support 5, blade 6 and blade controls 7.
Referring to FIG. 2 there is shown a substructure 4 for attachment 3. The substructure 4 is composed of a horizontal top frame member 8 having five depending vertical frame members 9, 10, ll, 12 and 13. The five depending vertical frame members 9, l0, 11, 12 and 13 are spaced and supported at the bottom by blade 14. The top frame member 8 and vertical frame members 9, 10, 11, 12 and 13 are formed of3 inch by 5 inch tubing of one-fourth inch thickness. Vertical frame members 10 and 12 have welded thereto blade support 5. Blade support 5 is comprised of blade hangers 15, 16, one-half inch plate welded to each side of the lower portions of vertical frame members 10 and 12. Vertical frame members 9, I0, 11, 12 and 13 are sheeted with three-sixteenths inch checker plate 17.
As seen in FIG. 3 truck 1 has a truck frame 18. Top frame member 8 and the upper portions of vertical frame members 9, 10, 11, 12 and 13 are welded to truck frame 18. A supporting strut 19 made of a one inch flat plate is welded between truck frame 18 and the lower portion of vertical frame members 9, 10, l 1, l2 and 13 and acts as a structural support. Blade hangers 15, 16 include apertures 20.
As seen in FIG. 4 the blade 6 is comprised of a central straight portion 21 and the inclined end portion 22 and 23. The central straight portion 21 is 66 inches in length and the inclined end portions 22 and 23 are each 17 inches in length. The overall length of the blade from end to end is 96 inches. The blade 6 is constructed of one-half inch rolled steel or blade material with 1 inch supporting steel to reinforce the blade. Approximate each end of the straight portion 21 of blade 6 and fastened to the blade are blade supports 24, 25. The blade supports 24, 25 are made from 3 by 5 inch tubing welding to the back of the blade 6 and blade reinforcements. As seen in FIG. 5 the blade supports 24, 25 have elongated apertures 26, 27 adapted to receive bolts 28 and 29. The blade 6 is mounted on blade hangers 5 so that elongated apertures 26, 27 are aligned with apertures 20 in blade hangers 15, 16 and bolts 28, 29 are inserted through the aligned apertures 20 in respective blade hangers 15 and 16 and blade supports 24, 25 to retain the blade 6 on blade support 5.
Blade controls 7 are seen in FIGS. 4 and 5. As seen in FIGS. 4 and 5 the inclined end portions 22 and 23 of blade 6 each have flanges 30 and 31 welded thereto. As seen in FIG. 5 the flanges 30 and 31 are above the lower edge of blade 6 and have flat portions 32 and 33 at the bottom. Welded to the truck frame 18 are hydraulic jacks 34, 35 each having a shoe 36, 37 engaging flanges 30 and 31 respectively for raising and lowering the blade 6. As seen in FIG. 1 the blade 6 has centrally located on its front surface a retaining means 38 adapted to receive a chain 39 fastened from substructure 4 to retaining means 38. When the blade 6 is not.
in use the blade 6 is pivoted about the bolts 28, 29 until the blade 6 is in horizontal position. The chain 39 is then fastened to retaining means 38 to retain the blade in horizontal position during travel, when blade 6 is not in use. The blade is used during travel as a storage unit for augers or like heavy equipment which must be transported to the drill site.
At the drill site the equipment stored on the blades is removed, the blade 6 is lifted slightly, the chain 39 is removed from retaining means 38 and the blade 6 is lowered.
The drilling is then commenced and when the drilling chips have built up around the hole the auger is removed, the blade height adjusted and the drill chips are pushed across the drill site out of the way. The blade height is adjusted during this operation so that the drill site remains level. The drill site has been levelled by large earth moving equipment to receive a conventional oil drilling rig before the truck and drill come onto the drill site. The drill site should be just as level after the truck and drill have drilled the surface hole and drill chips levelled as the drill site was before the surface hole was drilled. After the surface hole has been completed and the drill site levelled, the blade 6 is raised to the horizontal and retaining means 38 are fastened by chains 39 to substructure 4.
Changes in the substructure, blade support, blade and blade controls may be made without departing from the scope of this invention.
