- FIG. 8 is a detailed side elevational view of the means for mounting the body frame to the mast frame.
- FIG. 9 is a sectional view taken along line 9-9 of FIG. 8.
- Numeral l0 designates a vehicle for carrying derricks.
- a chassis frame 12 includes two parallel chassis side members 14 which extend along the length of vehicle and which are joined by a plurality of chassis cross-ties 16. Side members 14 are C-shaped in cross section with their cross-sectional open ends facing one another. Forward and rear wheel and axle assemblies 18 are mounted to chassis frame 12 in a conventional manner. On the front of chassis frame 12 is mounted a conventional vehicle cab 20.
- mast frame 22 Rigidly mounted above chassis frame 12 behind cab 20 is a mast frame 22.
- Mast frame 22 includes a rectangular front section 23 (FIG. 3) formed by two mast side members 24. a plurality of mast crossties 26, and two diagonal ties 28.
- Rigidly secured across the extreme rear end of front section 23 is a crossbeam 30.
- Gussets 31 reinforce the securement between crossbeam 30 and rectangular front section 23.
- Crossbeam 30 is rectangular in cross section and hollow along its length. It has a vertical thickness approximately twice that of the vertical thickness of rectangular front section 23.
- Rectangular front section 23 is mounted to the lower half of crossbeam 30 so that crossbeam 30 forms a forwardly facing abutment 32 (FIGS. 1 and 7), which projects above the extreme rear end of rectangular front section 23.
- a reinforcing diagonal 34 which is L-shaped in cross section (FIG. 4).
- Diagonal 34 reinforces crossbeam 30 so that it will minimize deflection of crossbeam 30 when stresses are exerted on one end thereof.
- a rectangular mast cutout 36 At the right end 35 of crossbeam 30 is a rectangular mast cutout 36. Mast cutout 36 is three-sided with its fourth side being open at right end 35.
- the left end 38 of crossbeam 30 includes a vertically disposed outrigger cutout 40.
- a rectangular control box 42 which extends upwardly from crossbeam 30.
- Extensible outrigger 44 includes an extensible foot 46 which is adapted to extendfrom an outrigger casing 48 so that it will engage the ground to support vehicle 10 when the derrick is in operation.
- a vertically disposed mast 50 which is rectangular in cross section and which fits snugly within mast cutout 36 where it is welded.
- the lower end of mast 50 protrudes a short distance below crossbeam 30.
- an outrigger pivot mount 52 At the extreme lower end of mast 50 on its outwardly disposed side is an outrigger pivot mount 52 to which is pivotally secured an articulated outrigger 54.
- Articulated outrigger 54 includes a foot 56 on its extreme outer end and is swingable about a horizontal axis from a folded position whereinit is vertically disposed alongside mast 50 to an unfolded position wherein foot 56 engages the ground.
- a hydraulic drive means 58 is pivotally secured at one of its ends to articulated outrigger 54and at the other of its ends to mast 50. As hydraulic drive means 58 extends, it causes articulated outrigger 54 to move from its folded position to its unfolded position.
- Turret 60 At the extreme upper end of mast 50 is mounted a turret 60 which is adapted to rotate on mast 50 about a vertical axis.
- Turret 60 includes flanges 62 which pivotally support a derrick 64 for swinging movement about a horizontal axis.
- a hydraulic cylinder 66 is pivotally connected at its opposite ends to turret 60 and derrick 64, respectively, and is adapted to extend and retract to cause swinging movement of derrick 64 about a horizontal axis.
- the particular type of derrick which is mounted on mast 50 does not comprise a part of this invention. Any type of derrick may be mounted on the extreme upper end of mast 50.
- Mast frame 22 is mounted above chassis frame 12 with mast side members 24 resting on chassis side members 14 and with crossbeam 30 resting across the extreme rear ends of chassis side members 14.
- Welded between crossbeam 30 and chassis side members 14 are a pair of tie plates 68.
- Tie plates 68 are L- shaped in cross section and are welded so that they embrace the upper and outer surfaces of chassis side members 14, thereby tying crossbeam 30 to side members 14.
- Mast frame 22 is further secured to chassis frame 12 by a plurality of securing plates 70 which are bolted and welded across the outer surfaces of mast side members 24 and chassis side members 14.
- U-shaped channel 72 Between the right-hand chassis side member 14 and the lower end of mast 50 is a U-shaped channel 72 which has one of its sides welded to tie plates 68 and the other of its sides welded to the inwardly disposed surface of mast 50. Extending transversely between the upwardly disposed walls of U-shaped channel 72 is a transverse channel 74 (FIGS. 2 and 3).
- U- shaped channel 72 and transverse channel 74 reinforce the lower end of mast 50 so as to prevent pivoting of mast 50 within mast cutout 36 of crossbeam 30.
- the weight of derrick 64 causes a torque to be applied to mast 50 with mast cutout 36 acting as a fulcrum. This torque would break or seriously weaken the securement of mast 50 to crossbeam 30 were it not for the stabilizing effect which channels 70 and 74 provide.
- U-shaped channel 72 serves as a step when the vehicle is fully assembled and in use.
- a vehicle body 76 (FIGS. 1 and includes a floor 78, two lateral walls 80, a forward wall 82, and a body frame 84 mounted below floor 78.
- Body frame 84 includes two parallel body side members 86 which are joined by a plurality of body crossties 88. Lateral walls 80 are provided with a plurality of compartments 90 having doors therein for storing tools and other equipment.
- Body frame 84 is of substantially the same rectangular shape as rectangular front section 23 of mast frame 22.
- Body 76 rests on top of mast frame 22 and chassis frame 12 with body frame 84 coinciding with and resting on top of rectangular front section 23 of mast frame 22.
- the eX- treme rear end of body frame 84 abuts against the forwardly facing abutment 32 of crossbeam 30.
- Each body suspension bracket 92 is comprised of a vertically disposed channel which is L-shaped in cross section and which includes a horizontal flange 94 at its lower end.
- Body suspension brackets 92 extend downwardly below the lower edges of body side members 86 and slidably embrace the outwardly facing surfaces of mast side members 24, thereby holding body frame 84 against lateral movement with respect to mast frame 22.
- a plurality of lower mounting brackets 96 are mounted on mast side members 24 immediately below and in alignment with body suspension brackets 92.
- Lower mounting brackets 96 include a horizontal flange 98 which faces horizontal flange 94 of suspension brackets 92.
- a bolt 100 extends slidably upwardly through apertures in horizontal flanges 98, 94, of body suspension brackets 96, 92.
- a coil spring 102 surrounds bolt 100 and extends between flange 94 and a washer 104 at the extreme upper end of bolt 100.
- This structural configuration provides spring mounting for body 76.
- springs 102 will permit movement to take place between body 76 and the mast and chassis frames.
- the mounting of mast 50 so that it is spaced apart from and disconnected from body 76 eliminates the twisting of body 76 resulting from deflection and twisting of mast 50, mast frame 22 and chassis frame 12.
- Crossbeam 30, mast 50, mast frame 22 and chassis frame 12 are free to twist and deflect independently from body 76.
- mast 50 which extends above floor 78 of body 76 is completely free from connection or engagement with body 76. There is no diagonal brace extending from mast 50 downwardly alongside lateral walls 80 of body 76 as in previous devices. This previous means of mounting the mast tied it structurally into the body and caused twisting of the body whenever movement of the mast took place. With the structural configuration of this invention, movement of mast 50 will impart little or no deflection to body 76.
- Outriggers 44, 54 are mounted on mast frame 22 and are not tied in with body 76. Thus when the outriggers are in use, the stabilizing support they provide is confined to mast frame 22 and they exert no stresses or strains on body 76.
- a mobile derrick for a vehicle comprising an elongated chassis drawn by said vehicle, derrick support means including a derrick support portion and an elongated mast frame provided on said chassis and rigidly mounted thereto, said derrick of said chassis, said mast frame and body frame being formed by transversely spaced side members, end members and a plurality of crosstie members, wherein one end of said mast frame abuts said derrick support portion and the corresponding end of said body frame extends adjacent said derrick support portion, said body frame support means being detachably secured to said derrick support means and resiliently mounted thereon for relative movement with respect to said derrick support means, said derrick and said chassis, and a vehicle body rigidly secured to said body frame support means for resilient movement with said body frame, whereby stresses imposed on said derrick and transmitted to said derrick support means and said chassis are substantially isolated from said vehicle body.
- chassis includes opposite chassis end portions and spaced and parallel side support members, said derrick support means comprising an elongated crossbeam provided at one chassis end portion of said chassis frame transversely mounted thereon.
- crossbeam further includes a pair of articulated outriggers provided at opposite ends of said crossbeam.
- said mast frame includes opposite mast frame end portions corresponding to said chassis end portions, one said mast frame end portion being rigidly secured to said crossbeam in abutting relationship therewith.
- said body frame support means includes opposite body frame end portions corresponding to said mast frame end portions, one said body frame end portion provided adjacent said crossbeam such that said body frame end portion is independently movable with respect to said crossbeam.
- crossbeam is of hollow configuration having a substantially rectangular cross section, said crossbeam including an internal diagonal brace secured to opposite sidewalls of said beam to reinforce said beam, said brace extending from one projecting end of said crossbeam toward the other projecting end thereof.
- crossbeam is of hollow configuration having a rectangular cross section, said crossbeam including an upwardly extending mast portion rigidly secured to one of said projecting end portions of said crossbeam.
- said derrick mast includes a tail portion depending from said crossbeam in substantial alignment with said upwardly extending portion of said derrick mast, said derrick further comprising a stabilizer channel disposed between said tail portion and said chassis frame in abutting relationship therewith to prevent twisting of said derrick mast with respect to said crossbeam.
- said stabilizer channel is of hollow configuration and open at one end to form a step that accommodates a persons foot.
