Definitions

  • This invention relates to a novel method and apparatus for banding tanks with steel reinforcement.
  • Large tanks are ordinarily reinforced' by steel bands or rods extending annularly or spirally therearound and the application of these rods to the tanks is a considerable task since it requires not only extensive scaffolding but also a substantial amount of manual labor in threading rod lengths through the scaffolding, raising them to the necessary elevation and connecting, laying and tensioning the rods in continuous length on the vertical tank wall.
  • the primary object of my invention is the production of an improved method and apparatus for banding tanks more eiciently and with less expenditure of time, labor and materials, the invention relating more especially to the application of continuous steel wire"circumferentially and spirally of the tanks and in taut condition placing the tanks under compression.
  • the invention contemplates the employment of a wire carrying and placing vehicle supported for movement around and adjacent to the outer face of the tank to be banded.
  • An end of the wire reinforcement is anchored at a starting point adjacent to the base or top of the tank and the 4vehicle carries the free portion thereof and winds it into taut contact with the tank as the vehicle proceeds therearound.
  • the vehicle is movable horizontally and circumferentially around the tank and means is provided for trailing the wire onto the tank and placing the succeeding convolutions progressively higher or lower and in predetermined proximity.
  • vthe vehicle is pulled by and along a cable extending around and in frictional'contact with the tank, this cable being either an independent and closed or complete annulus or a continuous part of the wire reinforcement trailed into tight engagement'with the tank, all as hereinafter described.
  • Means is also provided for holding and placing the reinforcement wire under a constant and uniform tension and for elevating the vehicle as it travels around the tank whereby to place the reinforcement convolutions at progressively higher elevations.
  • Thev operations are substantially continuous and mechanical, involving little manual labor and resulting in a strong, uniform and superior reinforcement.
  • a further feature of my invention contemplates the'proiecting of a suitable coating material from the wire wrapping vehicle onto and into bonding engagement with the previously placed wire convolutions beneath or above the vehicle as the vehicle passes the same in its wire wrapping travel. The placing of this coating material and thereby completing the entire operation all simultaneously and from the same vehicle comprises a further object of the invention.

  • the vehicle can be supported anddriven inany v convenient and desirable manner for performing this function, as by suspending the vehicle from above as illustrated in Figs. 1-6 or by supporting it on tracks at the base of the tank as illustrated in Fig. 9.
  • the vehicle is mounted to move around the tank and trail the banding wire therefrom and into predetermined tensioned contact with the tank.
  • 4 indicates a vehicle or platform suspended from a boom I6 to a position overhanging the outer face of the side wall l (Fig. 1).
  • the boom is supported on a carriage I8 in rolling contact with the top of the tank and anchored by a cable for swivelling movement about a fixed post 2

  • the clutch lever is operated by a hand rod 83.
  • the banding wire 84 is drawn from a reel 85 supported on the ground at the base of the tank and mounted to rotate about a horizontal axis 86 to unwind the wire and torevolve about a vertical axis 88 to take the twist out of the wire as hereafter described.
  • the wire passes from the reel upwardly over a sheave 89 supported on a pole 90 above the tank. From thence the wire passes downwardly and into and through a funnel-like guide 9
  • the reel 85 can occasionally be rotated on its vertical axis in a direction and to an extent removing this twist.
  • the wire 64 passes over a sheave 92 supported on the boom
  • the wire continues therefrom around a grooved wheel 95. fixed to the shaft of a brake comprising two brake drums 86 supported in a block 91, and from thence into contact with the tank wall l2.
  • 02 of the brake rests atly on the frame 4 (Fig. 3) and is adjustable about a center clamping bolt

  • the carriage I8 shall travel synchronously with the vehicle I4 and the following means, illustrated in Figs. 4 and 5, is provided for effecting this function.
  • the carriage is driven by the engine 28 which can be of the internal combustion type if desired but, as illustrated, it is driven from compressed air received through a hose
  • the valve has a controlling arm
  • extends downwardlybetween these pins and from thence downwardly between two spaced pins
  • the valve is closed. Movement of the vehicle I4 forwardly swings the cable forwardly and opens the valve whereby driving the carriage I8 forwardly, whereas any lagging of the vehicle behind the carriage swings the cable rearwardly and closes the valve.
  • the movement of the carriage is synchronized with the movement of the vehicle.
  • Concrete tanks preloaded by rod reinforcement are usually finished by placing ⁇ a coating of ce..
  • a further feature of my invention herein contemplates the placing of this coating on the tank from the vehicle I4 simultaneously with the banding operation, the cementitious composition being projected onto the banded portion of the tank following and progressing with the 'banding thereof.
  • the composition is projected from a cement gun
  • the cement gun can be operated continuously or at such time periods as is necessary to provide a coating
  • This banding-coating combination of operations completes the tank wall at one passage of the vehicle thereover as will be apparent.
  • each convolution of wire wrapped permanently onto the tank from the wheel 99 is at an elevation higher than the previously placed convolution, this being effected by elevating the vehicle which, as illustrated in Figs. 1-7, is performed automatically and synchronously with the travel of the vehicle around the tank.
  • the drive from the shaft 52 through the chain 94 and speed reducing connections to the drum 36 rotates the drum very slowly in a direction automatically or by suitable means giving a continued and gradual increase of vehicle elevation as the operation proceeds, or the vehic.: can-be elevated by means other than the engine 60.
  • the engine can be employed to elevate or lower the vehicle independently of its movement around the tank byopening the clutch 60.l
  • 41 When the vehicle IQ has banded a predetermined portion of the tank therebeneath, the cement gun
  • the gun is oscillated to project the composition evenly' over the rods and wall to be coated and is operated during such time period as is necessary to build up the coating
  • the maximum length of continuous wire that can be provided in a roll is ordinarily limited to less than that required completely .to band a tank and it is therefore 'necessary either to anchor the ends of the wrapped and tensioned wire to the tank or splice one end of each new r-oll to the previously placed wire.
  • Such operation can be performed in any convenient and suitable manner. I prefer however to splice the ends either before they pass to the rolls 93 or after they leave the block
  • Suchholding can be effected by an expansion bolt tapped into the tank, similar to the anchoring illustrated at
  • Supported on and beneath the vehicle Il is a frame
  • the reel is, positioned to feed the wire upwardly to the rolls 93 and from thence to a grooved wheel corresponding to the grooved wheel 95.
