Definitions

  • the present invention relates to a turntable.
  • the object of the present invention is to provide a turntable which can swivel while carrying heavy load thereon.
  • the present invention provides a turntable supported by a circular rail having a series of holes provided along the rail for cooperation with cylinder mechanism mounted on the turntable for rotating the turntable by sequential extension and retraction of the cylinder mechanism, advancing the turntable by sequential engagement of the mechanism from one hole to the next.
  • FIG. 1 is a plan view showing a turntable according to the present invention
  • FIG. 2 is a side view of the turntable
  • FIG. 3 is a sectional view taken along the line AA in FIG. 1;
  • FIG. 4 is a plan view of the principal parts of the turntable.
  • FIG. 5 is a side view showing operation of the turntable.
  • the turntable comprises a square frame 2 having beams 1 arranged diagonally across said frame and support frames 3 secured to the undersides of four cor ners of said frame 2. Beneath said support frames are provided sliding members which are mounted on the circular inner and outer rails 4 to support the load. In the center of the frame 2 is provided a pivot 5 which rotatably engages with the cylindrical member ofa center post 6 to permit the frame to turn about the center post. Load is received by two opposed frame members 20 of the square frame, and for this reason, these frame members are positioned at higher level than the other side frame members.
  • Each support frame 3 is provided with a pair of hydraulic cylinders 7 and 8 serving as driving means.
  • a pair of plates 10 are horizontally projected from opposite sides of each of said cylinders 7 and 8 and each plate is slidably engaged with the corresponding guide groove 11 provided in the support frame 3 as shown in FIGS. 3 and 4.
  • the piston rod 12 of each said cylinder is joined by a universal joint (not shown) to a pin 13 provided in the frame 3.
  • a vertical pin 14 which may be vertically slided by the operation of the hydraulic cylinder (not shown) so as to engage with one of a plurality of holes 15 arranged equidistantly between rails 4 on the ground.
  • This cylinder mechanism is provided tangentially to the rails, and each guide groove 11 is provided with a bevel 16 designed in such a manner that the cylinder will slightly rotate when it slides in the groove as described hereinafter.
  • cylinder mechanisms are provided in the rotatable frame in such a manner that the frame may be turned by operation of the cylinder mechanism and engagement and disengagement of the cylinder mechanisms with the holes provided in plurality and in circular arrangement above the ground, so that heavy load mounted on the frame can be easily turned with the frame.
  • a turntable comprising circular rails provided on the ground, a frame for receiving a load mounted on said circular rails and turned along the rails, cylinder mechanisms provided in said frame so as to be extended and contracted tangentially to the circle of rotation, a plurality of holes provided along the rails, and means for engaging or disengaging a free end of each cylinder mechanism with one of said holes, whereby the frame can be turned by extension and contraction of said cylinder mechanisms and alternate engagement and disengagement thereof with said holes.
