In the known pipe supports of this kind the carrying arms are internally secured to the wall of the heating device.
  • a further object is to provide means to replace the pipe support without interrupting operation.
  • the carrying arm of a pipe support extends with a slight play through the wall of the heating device and is rotatably suspended on a horizontal transverse shaft outside the heating device, the carrying arm being detachably connected with said horizontal transverse shaft, so that it may be replaced outside the heating device.
  • the heating device need not be put out of operation during the replacement of the carrying arm, since no labor has to be carried out in the interior of the heating device.
  • the carrying arm is blocked against an undesired rotation by means of a releasable locking member adapted to be operated outside the heating device.
  • the pipe support according to the invention has the important additional advantage that it may be carried out as an alternative in such manner that a torque is exslight movements which may be of importance, for instance, if the pipe support is arranged in the vicinity of the fixed inlet or outlet portion of the pipe. It is, of course, possible to support a pipe by a plurality of carrying arms, of which only a few are rotatable during operation, while the other ones are in a blocked position.
  • FIG. 1 shows a vertical cross-section according to the plane I--I in FIG. 2 of a first embodiment of the pipe support according to the invention, wherein the carrying arm is blocked against rotation.
  • FIG. 2 shows a side-view of the pipe support shown in FIG. 1.
  • FIG. 3 shows a cross-section according to the line "I- -III in FIG. 1.
  • FIG. 4 shows a vertical cross-section of a modification of the pipe support according to the invention, which may be rotated during operation.
  • FIG. 5 shows partially in a vertical cross-section and partially in a side-view a further embodiment of the pipe support according to the invention.
  • FIG. 6 shows a fragmentary view of FIG. 4 with a spring instead.
  • the pipe support shown in FIGS. 1-3 serves to support a bundle of pipes comprising vertical pipe sections 1 arranged in the interior of a heating device, such as a boiler.
  • the pipe support comprises a flat carrying arm 2 extending in a vertical plane and provided at its upper edge 3 with a recess 4 supporting a bend at the top of the pipe 1.
  • the carrying arm 2 extends with a slight play through the wall 5 of the heating device, which comprises flat metallic plates 5' on the outside and a layer 5" of masonry on the inside.
  • the carrying arm 2 fits between two parallel carrying strips 6.
  • the strips may also contain holes that are elongated in the longitudinal direction of the strips, in order that the carrying arm 2 may be adjusted with respect to the strips.
  • the strips 6 are interconnected by a transverse rib 8 extending underneath the carrying arm 2 and welded to both strips 6.
  • the strips 6 are detachably and rotatably supported on a horizontal transverse shaft 9.
  • the shaft 9 extends through two ears 10 arranged on the outside of the tops of the strips 6 and fixed to an upper comer profile 11, such as angle iron, externally welded to the plates 5' of the wall 5 of the heating device.
  • the horizontal transverse shaft 9 is provided at one of its ends with a head 9' engaging one of the ears 10, whereas the other end, which extends freely outside of the other ear 10, is provided with a transverse bore, in which a split pin 12 has been inserted as a detachable securing means.
  • the strips 6 may be latched by a releasable latching member in a substantially vertical position by means of a horizontal bolt 13 extending through a bore of the plates 5 of the wall 5 of the heating device and by means of an aligned bore in a lower corner profile 14 welded to the plates 5'.
  • the bolt 13 extends to the outside between the strips 6 and carries an annular blocking plate 15, which is locked by means of a nut 16 screwed onto the bolt 13 and provided with a handle.
  • the blocking plate 15 engages the lower part of the strips 6 on the side remote from the heating device.
  • a spacing ring 17 arranged on the bolt 13 is enclosed in the latched position of the strips 6 between the lower corner profile l4 and the strips.
  • the correct end position of the carrying arm 2 may be obtained, in which position the carrying arm is blocked by the cooperation of the strips 6, the bolt 13, the blocking plate 15 and the nut 16.
  • the axis of the horizontal transverse shaft 9 and the horizontal centerline 18 of the pipe section engaged by the carrying arm lie substantially in a common horizontal plane.
  • the lower edge 19 of the opening in the wall 5, through which the carrying arm extends, lies in a cylindrical surface of which the axis coincides with the axis of the horizontal transverse shaft 9.
  • the lower edge 20 of the carrying arm 2 lies in a cylindrical surface, of which the axis coincides with the axis of the horizontal transverse shaft 9 as far as the lower portion of the carrying arm cooperating with the opening in the wall is concerned, while the lower edge of the remaining portion lies either on said cylindrical surface or inside the same.
  • the nut 16 is loosened, after which the strips 6 may be turned to the outside together with the carrying arm clamped between the strips until the carrying arm is entirely outside of the wall 5 of the heating device. After that, the split pin 12 is removed and the horizontal transverse shaft 9 is slid out of the ears 10, so that the strips 6 and the intermediate carrying arm 2 are relased. After removal of the bolts 7 the corroded carrying arm 2 may be removed and replaced by a new carrying arm, which is secured between the strips 6 by means of the bolts 7, after which the strips 6 are rotatably suspended on the horizontal transverse shaft 9.
  • the strips 6 are turned to the inside of the heating device together with the carrying arm 2 in such manner, that the recess 4 in the top edge 3 of the carrying arm 2 engages the bend of the pipe 1 during the last portion of its rotation, even if the pipe bend should have slightly sagged.
  • FIG. 4 shows a modification of the pipe support according to the invention, in which the carrying am 2 is also rotatable during the operation, which may be of importance, for instance, if the carrying arm 2 is arranged in the vicinity of the fixed inlet or outlet portion of the bundle of pipes.
  • substantially triangular carriers 24 are provided instead of the strips 6, which are again interconnected by means of a transverse rib 8 and between which the carrying arm 2 is secured by means of the bolts 7.
  • the triangular carrying plates 24 are detachably and rotatably suspended with their top ends on the horizontal transverse shaft 9 in the same manner as the strips 6 in the embodiment according to the FIGS. 1-3.
  • a force is exerted on the carrying plates 24 on the side of the horizontal transverse shaft 9, which is remote from the heating device, the said force having a vertical downwardly directed component. It is possible, for instance, to suspend a weight 31 on the carrying plates 24 at 25; as an alternative, the force may also be exerted by a spring (32) as shown in FIG. 6 or the like. Due to said force, a torque is exerted on the carrying arm 2 through the intermediary of the carrying plates 24 and the bolts 7, so that the carrying arm is loaded in the direction to the interior of the heating device.
  • the carrying plates 24 are turned in an upward direction until the carrying arm lies entirely outside the heating device. After that, the carrying arm may be removed and a new carrying arm may be mounted in the above-described manner.
  • FIG. 5 shows two pipe supports according to the invention lying one behind the other in a staggered fashion and adapted to support a bundle of pipes having horizontal pipe sections 26.
  • the axis of the horizontal transverse shaft 27, on which the carrying plates 24 are suspended is not arranged in the same plane as the horizontal axis 29 of the pipe section engaged by the carrying arm 28, but at a higher level spaced above the plane of the axis of the pipe section at a distance of about three times the pipe diameter.
  • the height of the carrying arm 28 may be reduced, so that it may be brought outside the heating device by a rotation of the carrying plates 24 through an angle of about 45.
  • Both strips 6 (FIGS. 1-3) and the carrying plates 24 (FIGS. 4-5) have a rounded upper portion 30, through which the horizontal transverse shaft 9, or 27 respectively, extends centrally.
  • the carrying arm 28 is rotatable during the operation, it is also possible to combine the carrying arm 28 with the strips 6 shown in FIGS. 1-3.
