Definitions

  • This invention relates to a well servicing mast mounted on a vehicle, and more particularly to a mast that can be raised and lowered.
  • length of the mast thus has been limited to the length of the vehicle plus the distance that it has been feasible for the mast to project ahead of it.
  • the mast is formed from two sections that are hinged together end to end.
  • the lower section is much shorter than the taller section.
  • the upper mast section projects several feet from both ends of the vehicle, and the lower section is below the projecting rear end of the upper section and has its front end pivotally supported on the rear end of the vehicle.
  • a reclining telescoping brace has its rear end pivotally connected to the rear end of either of the mast sections.
  • a folded lifting toggle brace reclines above the vehicle and is formed from two super-imposed links having their front ends connected by hinging means.
  • Means mounted on the vehicle in front of the lower mast section pivotally support the rear end of the lower link as well as the front end of the telescoping brace.
  • the rear end of the upper link is pivotally connected to the upper mast section.
  • a sheave is carried by the rear end of one of the mast sections, and a winch is mounted on the vehicle.
  • a raising line is connected with the tog gle brace near its hinge connection and extends rearwardly around the sheave and then forward to the winch. Consequently, when the line is reeled in by the winch it will swing the lower mast section andthe upper toggle link forwardand upward to raise the reclining upper section to a higher elevation while simultaneously telescoping the telescoping brace, and then will straighten 6 Claims.
  • the toggle brace in order to swing the upper section of the mast upward and rearward to upright position on the lower section.
  • a pair of parallel abutting plates are fastened to the adjoining link ends of the straightened toggle brace and project forward'from them. These plates limit the rearward movement of the brace and can be bolted together to lock the brace in straight position.
  • FIG. 1 is a side view of our well-servicing equipment ready for the road;
  • Fig. 2 is a schematic side view showing the mast partly raised
  • Fig. 3 is a fragmentary side view showing the raised mast
  • Fig. 4 is a rear view of the vehicle showing the raised mast
  • Fig. 5 is a view taken on the line V-V of Fig. 3.
  • a platform I is rigidly mounted on the frame of a truck 2 over its rear wheels.
  • a superstructure A having front posts 3 near the middle of the platform and rear posts 4 at its outer or rear end. All references herein to front and rear relate to the front and rear ends of the truck.
  • the front and rear posts of the superstructure are connected by substantially horizontal spreaders 6.
  • the superstructure also includes intermediate posts 1 that extend above the spreaders and have their upper ends braced by inclined braces 8 and 9.
  • This superstructure supports a collapsible or folding mast formed from a rather short lower section B and a much longer upper section C.
  • the lower section is formed from a pair of parallel legs ll connected by horizontal and diagonal braces l2 and 13.
  • the lower ends of the legs are pivotally mounted in shoes [4 on top of rear superstructure posts 4.
  • the upper ends of these legs are connected by hinges Hi to the lower ends of the opposite sides of the upper section of the mast.
  • the cross member preferably is connected to the upper mast section.
  • each of the trunnions l8' is the upper end of the inner member IQ of a telescoping brace D that has a tubular lower member 20 in which the upper member can slide when the brace is not fully telescoped and locked by a pin 2
  • a conventional utility winch 34' mounteded on the tr ck'is a conventional utility winch 34', bywhich the mast is lowered and raised.
  • thecabl'e' extends" up across the front of a sheave 31 (Fig. 4)

  • sheave 4 carried by' a bracket thatis'pivotally siip'pbrted by one side of the lower toggle link 25.
  • This bracket is spaced by a horizontal strut 43 from a similar bracket 44 pivotally connected to the otherside of the same toggle linkand carrying a sheave 45
  • the cable extends along the strut and around this'la'st' sheave, and then backward and down 'over a sheave 41 mounted on the other trunnion 13.
