Definitions

  • the gate pivot is formed by a rotatably mounted tubular beam on which the frame is mounted by means of bearing members which are provided on the frame and engage peripheral surface portions of the tubular beam spaced apart at a sufficient angle, and which members are locked in such engagement by bolts that are secured to the frame and extend therefrom and into securement with the tubular beam along lines located between radial lines through such surface portions.
  • a tank for the sector float of the gate is supported at one end by the walls of the water course and at its other end by rollers engaging the peripheral surface of the tubular beam.
  • Automatic gates of the sector type with which this invention is concerned are usually constituted of an upstream, arcuately-shaped gate apron centered on the axis of rotation of the gate, a downstream sectorshaped, gate float centered on the same axis, a frame connecting the gate apron and the float, and ballasting means for balancing the gate to effect its automatic operation.
  • this type of gate may function correctly in its automatic operations, it is necessary that certain of its parts be centered on the axis of rotation of the gate within relatively close tolerances.
  • this type of gate is usually made as a unit with the frame and float welded to a transverse beam, the longitudinal axis of which is coincidental with the axis of rotation of the unit, and with the gate apron and at least one ballast container welded to the frame. It will be apparent however, that such a unitary gate, especially those which are of large construction, presents many problems during their transportation and in handling.
  • the aforesaid purpose is essentially accomplished by making the gate pivot of a tubular beam, providing the frame arms of the gate with protruding parts which bear on portions of such tubular beam spaced apart at a sufficient angle, and locking such parts to the tubular beam by bolts which extend from the frame arms into the tubular beam along lines located between radial lines through such surface portions.
  • a tank for the sector float is supported at one end by the walls of the water course and at its other end by rollers carried thereby and arranged to travel transversely of the length of and on the peripheral surface of the tubular beam.
  • FIG. 1 is a schematic, side elevational view of the gate
  • FIG. 2 is a partial, vertical sectional view of an enlarged scale illustrating the method of assembling the frame and the sector float tank on the tubular pivotal beam;
  • FIG. 3 is a top plan view of the apparatus shown in FIG. 2 with the balancing container omitted for the sake of clearness;
  • FIG. 4 is a partial, side elevational view of a modified method of assembling the frame on the tubular beam.
  • the automatic gate includes a frame 3 which extends upstream from the gate pivotal axis 2 and on'the outer upstream end of which is mounted a sector-shaped apron 1 radially disposed to the pivotal axis 2.
  • the gate unit further includes a hollow sector float 4 which is also centered for pivotal movement about the axis 2 and which moves in a tank 5 that is in communication with the downstream reach of the canal.
  • the float 4 also functions as a ballasting container for ballast material 30 which is loaded therein when the gate is in its closed position as is shown in FIG. 1 of the drawings. Sufficient of the ballast 30 is added until the gate is just on balance in its closed condition.
  • the gate is then balanced in its open position by loading ballast 31 in a container 6 which is mounted on the frame 3 so that it is located vertically above the pivoted axis 2 when the gate is in its closed position as in FIG. 1.
  • ballast 31 in a container 6 which is mounted on the frame 3 so that it is located vertically above the pivoted axis 2 when the gate is in its closed position as in FIG. 1.
  • the pivotal axis 2 of the gate is coincidental with the longitudinal axis of a tubular beam 22 which extends transversely across the canal 23, in FIG. 3, and is rotatably supported at its ends by bearings 24,24 mounted in the side walls 25,25 of the canal.
  • the frame 3 mounted on the tubular beam 22 for pivotal movement about its longitudinal axis 2, is constituted of two arms 26,26 which at their downstream ends rest on the beam 1 22.
  • Each frame arm 26 is is composed of two U-shaped beams welded together to form a hollow rectangularlyshaped arm and is separately connected to the beam 22.
  • the arm connecting means comprises a plate 8 that is welded to the outer side wall of the hollow arm so that its lower edge rests on a surface portion 10 of the beam located vertically above the pivotal axis 2 when the gate is in its closed position as in FIGS. 1 and 2.
  • bearing plate 8 protrudes below the surface of the frame arm 26 and its lower edge 8 is arcuately-shaped to rest on the peripheral surface of the tubular beam 22.
  • a second bearing plate 7 which depends downwardly from such arm and is provided with an arcuately-shaped downstream edge portion 7' that bears against a beam surface portion 9 disposed upstream of the pivotal axis 2 and at an angle of approximately to the beam surface portion 10.
  • the plate 7' in addition to serving as a means for securing the frame arm to the beam 22, cooperates with the latter to bear the thrust of the hydraulic forces exerted on the apron l and transmitted along the beam 26. It may be noted at this time that at the two surface portions 10 of the beam 22 engaged by the bearing plates8 will be subjected to lines of force which are, predominately of the weight of the frame, whereas the two surface portions 9 of the beam 22 engaged by the bearing plates 7 will be subjected to lines of force which are predominately of the hydraulic thrust on the apron.
  • the angle between the two surface portions 9 and 10 should preferably be sufficient to cover all of the angular travel of the resultant of the thrust exerted by the weight of the gate on the tubular beam and of the variable hydraulic thrust that is exerted on the apron of the gate and transmitted through the frame 3 to the tubular beam 22.
  • the tubular beam 22 is locked in the aforesaid relation with the bearing plates Tan 8 of each frame arm 26, by a threaded bolt 11 whose head end extends through an apertured block or socket member 12 permanently fixed to each frame arm.
  • the threaded end 13 of the bolt 11 is threadedly engaged with a female thread provided in one end of an elongated rod-like nut 14 diametrically arranged within the tubular beam 22 and secured at its ends to diametrically opposed portions of the beam wall.
  • the opening in the socket member 12 for the bolt 11 is fixed so that its centerline is between the radial lines through the surface portions 9 and of the beam 22 that indicate the two variable componentlines of force exerted on the tubular beam by the weight of the gate and the variable hydraulic thrust on the apron.
  • This direction of the bolt may coincide with a line which bisects a bearing angle of 90 as shown in FIG. 2 of the drawings, but it may be positioned at a different angle with respect to such lines of force.
  • the direction of the bolt should be within the angle formed by the two bearing surfaces 7'- and 8 and such as to maintain the bearing plates 7 and 8 firmly seated on the periphery of the beam 22 particularly in the absence of hydraulic thrust.
  • the bolt 11 and the nut member 14 will provide a completely rigid assembly of the frame arms and tubular beam that will not be modified during the automatic operations of the gate even under extreme conditions and until it is positively dismantled for purposes of repair, or the like.
  • the sector float 4 is permanently connected to the downstream ends of the frame arms 26 in any suitable fashion as by welding.
  • the tank 5 in which the float moves is fixedly secured as its downstream end to the side walls 25,25 of the canal 23 by a unit which is essentially constituted of a transverse beam 17 whose ends may be 4 permanently connected to such canal side walls in any suitable fashion as by sealing them in the concrete material forming such walls, and two parallelly arranged bracket members 15,15 that are permanently secured in spaced relation to the transverse beam 17.
  • the beam 17 is a tubular beam and the bracket members 15,15 form the upstream projecting ends of two plates 15',l5.
  • the illustrated unit further comprises a tubular transverse beam 18, which is supported by the cantilevered ends of plates 15 ,15, and a cross tension bar 33.
  • a platform 19 which extends transversely from one canal side wall to the other so as to afford a service platform for the caretakers of the gate.
  • the tank 5, at its upstream end, is provided with two transversely spaced pairs of rollers, each pair comprising an upper roller 20 and a lower roller 21.
  • the rollers 20,20 of each pair bear on a track 22 formed on the tubular pivot beam 22.
  • the tank 5 is fixed at its downstream end with relation to the canal walls, and is supported at its upstream end by the beam 22, the pairs of rollers 20 and 21 enabling the gate to pivot freely in its operations with relation to the fixed tank 5.
  • each pair of rollers travels on the peripheral surface of its associated band 22.
  • the peripheral surfaces of the bands 22', 22 are machined to provide smooth tracks for the rollers 20 and 21.
  • each pair of bearing plates 7 and 8 associated with each frame arm 26' have been constructed as a single plate 35 provided with one arcuately-shaped edge 35 which extends throughout the range of movement of the resultant of the weight and hydraulic thrusts exerted on the tubular beam 22.
  • the bearing plates 35 may be secured to the frame arms 26' in the manner of the bearing plates 7 and preferably are provided with upwardly extending extensions 35" which forms supports for the ballast container 56.
  • the construction of FIG. 4 is similar to that shown in FIGS. l-3 and the gate is secured to the tubular beam 22 by bolts 11 and nuts 14 inthe manner described in the discussion of the construction of FIGS. 1-3.
