3 Claims: 1
The invention relates to a handling board or platform, and more especially to an adjustable safety board or platform for handling tubing, piping or casing material for oil wells or thelike.
The primary object of the invention is the provision of a board or platform of this character, wherein the drill string or casing sections for an oil well can be conveniently handled within the oil well derrick, either for the placing or pulling of the casings, tubing, sucker rods or drill pipes, and without liability of injury to a workman, the board or platform being of novel construction and unique in the arrangement thereof for the raising and lowering thereof.
Another object of the invention is the provision of a board or platform of this character, wherein its carriage is movable perpendicularly on a track, and the board or platform through swinging action can be swung vertically from a horizontal position and is therefore safe in the use thereof, and the carriage can be latched in a selected raised or lowered position on the track for servicing purposes.
Afurther object of the invention is the provi sion of a board or platform of this character,- wherein the stabbing operation can be carried forth with ease and dispatch, and such platform or board is extended to a point adjacent to the axis of the well, thus giving the workmen close approach to the work and without interference by other mechanism of the oil well rigging.
A still further object of the invention is the provision of a board or platform of this character, which is simple in construction, thoroughly Figure 1 is a fragmentary side elevation of an 3-3 of Figure 1, looking in the direction'of'the" Figure 6 is 'a'sectional viewon the line" 6 6' of Figured.
Similar reference characters indicate corresponding parts throughout the several views in.
the drawings.
Referring to the drawings in detail, -A designates generally a portion of an oil well derrick in which is arranged the "board or platform de noted. in its entirety at B, and hereinafter fully described.
The derrick A has connected tothe girders I0, connecting its legs I2 aperpendicularly disposed I-'beam' l4" forming'a track on which travels vertically a carriage l6, having the spaced side'p-anels or cheeks I8, between which are horizontally journalled opposed upper and lower tracking rollers 20 by means of pins 22 which straddle the beam i4 and have trackage on the base and head flanges 24 and 26 respectively thereof, whenthe carriage I6 is moved upwardly and downwardly uponthis beam'in the use of the board or platform.
The hanger frame 28 for the beam M which is attached in any suitable manner to selected gird ers Illof the derrick A, has built therewith a' hoisting crane 30 which at the upper end 32' is adapted to be wound on and unwound from awindlass 36in bearing fittings on the side cheeks or'panels l8 of thecarriage Hi; the Windlass 36 being equipped with a hand crank 38 for the manual operation thereof, so that the carriage can be raised or lowered on the beam 14, as should be obvious from the drawings.
The carriage It at its bottom and centrally thereof has a horizontally positioned hanger rail 40 for an adjustable telescopic connection with a square shaped sleeve 42 secured to the board or platform 44, by means of the hangers 46 which are welded to the platform 44 at 48, which at the sides and ends thereof is fitted with a guard railing 50, supported by the corner uprights 52 as stated. The bottom of the board or platform 44 has the sleeve 42 secured centrally thereof which telescopically engages over the rail 40, which together with the sleeve are of square formation in cross-section to eliminate the turning of the said sleeve thereon when engaged with such rail and aligned openings 53 in rail 40 and sleeve 42, receive bolts 55 to retain the sleeve in adjusted relation with the rail. The hanger 40 is pivotally mounted between the cheeks or panels I 8 by means of the pin 54 and is held against lowering from horizontal position on its pivot 54 by a stop 56, located in the carriage l6. However said rail can swing upwardly from horizontal position, without interference by the stop 56, when the platform or board 44 is not to be used.
The platform 44 is further strengthened in an extended or retreaded positions by a bar 58 one end of which is arranged to be received in eyes 60 on the platform or board 44 the other end of which is pivotally received in an eye 62 on laterally extended channel arms 64 welded to the panels 18 in diametrically opposed parallel relation with each other. The adjustment of the platform or board 44 allows it to be brought closer to or away from the work, a portion thereof being denoted at 66 within the derrick A, and this work in this instance is shown as a pipe or well casing.
On the head flange 25 of the beam M are vertically spaced racking projections 68, while mounted within the carriage i4 is a spring tensioned ratchet acting dog or detent 10 supported in a horizontal pivot axle 1'2, its tensioning spring being denoted at 14 and function to normally hold the dog or detent in the path of the projections 68 for latching engagement therewith to prevent the lowering of the carriage on the track beam, yet permitting the said carriage to be raised by the hoisting cable 34 when the Windlass 36 therefor is manually operated, the dog being controlled by the cable 16 fastened to the platform railing at some convenient location.
The board or platform 44 functions as a stabbing board against which rests the work during the disconnection operation of tubing, piping, drill string, casing or the like for an oil well. The platform or board 44 is usable for pulling or placing of tubing, piping, drill string, casing or the like from and in an oil well, without liability of workmen to injuries 01' damage to the work.
The free end of the platform or board 44 approaches the vertical axis of the derrick A, where the stabbing operation is usually carried forth and assumes a horizontal position when in use, but when not in use is raised vertically to an upright postiion out of the way.
What is claimed is:
1. A platform for an oil well derrick having horizontal girders, comprising a perpendicularly arranged I-beam forming a track secured within the said derrick, a carriage having traction rollers interfitting the beam for travel of the carriage thereon, a crane rising above the beam, a vertically swinging rail carried by the carriage, means for preventing the swinging of the rail downwardly below a horizontal plane, a platform assembly adjustably supported on the rail, and means for latching the carriage in a determined position vertically on the beam laterally extended channel arms secured to the rear of said carriage, and means secured to aid arms and to said platform for aiding the rail in supporting said carriage.
2. platform for an oil Well derrick having horizontal girders, comprising a perpendicularly arranged I-beam forming a track secured within the said derrick, a carriage having traction rollers interfitting the beam for travel of the carriage thereon, a crane rising above the beam, a vertically swinging rail carried by the carriage, means for preventing the swinging of the rail downwardly below a horizontal plane, a platform assembly adjustably supported on the rail, means forlatching the carriage in a determined position vertically on the beam laterally extended channel arms secured to the rear of said carriage, and means secured to said arms and to said platform for aiding the rail in supporting said carriage, and means for raising and lowering the carriage on the beam.
3. A platform for an oil well derrick having horizontal girders, comprising a perpendicularly arranged I-beam forming a track secured within the said derrick, a carriage having traction rollers interfitting the beam for travel of the carriage thereon, a crane rising above the beam, a Vertically swinging rail carried by the carriage, means for preventing the swinging of the rail downwardly below a horizontal plane, a platform assembly adjustably supported on the rail, means for latching the carriage in a determined position vertically on the beam laterally extended channelarms secured to the rear of said carriage, and means secured to said arms and to said platform for aiding the rail in supporting said carriage, means for raising and lowering the carriage on the beam, and a guard railing about the sides and one end of the platform assembly,
