Definitions

the invention relates to a restraint for Pipe and heat exchanger high-pressure cleaning devices, with a retention part, by means of which one in the tube or Heat exchanger inserted nozzle, probe or the like. in the pipe or Heat exchanger is retained, a positioning device, by means of which the retaining part in any position on Pipe or heat exchanger mirror can be positioned, and one Holding device by means of which the retaining device on Pipe or heat exchanger can be fixed.
the positioning device a first telescopic arm and a second telescopic arm has, the first of which is telescopic at one end stored and fixable on the holding device is adjustable at its other end with one end of the second telescopic arm, which is connected to its other End of the retaining part.
This allows the retention part at any small distance and at any point of the Pipe or heat exchanger mirror can be arranged so that leakage of the probe with every conceivable cleaning process, Nozzle or the like the high-pressure cleaning device from the Heat exchanger or from the pipe can be reliably prevented can.
the first telescopic arm is advantageously mounted on its other End of a rotating part on which the second telescopic arm with one end telescopically supported and fixable is. This makes it easy to convert possible, the retention part of each tube of a heat exchanger assign the restraint, with a high operational security is maintained.
the first Telescopic arm has a cross sleeve at its other end, in which one end of the second telescopic arm can be moved or is telescopic and fixable.
the holding device of the retaining device according to the invention can, for example, as a flange terminal or Pipe connection clamp be formed.
the holding device expediently has the inventive device Retaining device a square sleeve for sliding or telescopic and fixable holder one end of the first square telescopic arm. This can ensure that the distance between the restraining part of the restraint and the Pipe or heat exchanger mirror always in the desired way can be selected.
first Telescopic arm For the rotatable connection between the first and the second Telescopic arm, it is advantageous if the other end of the first Telescopic arm is designed as a pivot pin.
the rotating part can then have a swivel bushing with which it rotates on the pivot pin of the first telescopic arm sits, the rotating part furthermore has a square sleeve, in which one end of the square second telescopic arm moveable or telescopic and fixable is. This can be done through simple and therefore high Dimensions reliable mechanical components or configurations the adjustability between the telescopic arms ensured become.
the swivel bushing is also expediently by means of a locking device preferably formed by brake screws fixable on the swivel pin.
FIG. 1 Restraint device serves to prevent that a nozzle, probe or the like.
a heat exchanger high-pressure cleaning device the one at the free end High pressure line of the heat exchanger high pressure cleaning device is arranged from a tube of the heat exchanger emerges and a significant risk to operating personnel or creates furnishings and equipment.
the restraint device shown in FIG. 1 has a holding device in the form of a flange terminal 1 on that on a pipe flange, not shown in the figures or the like.
Heat exchanger is firmly attachable or fixable.
a square sleeve 2 is provided on the flange connection terminal 1, in the movable or telescopic and fixable one end of a first telescopic arm 3 is supported.
the first telescopic arm 3 is designed as a square in cross section.
the fixation of one end of the first telescopic arm 3 within the square sleeve 2 of the flange terminal 1 is done by means of a locking screw 4, which in Figure 1 is only shown in principle.
the first telescopic arm 3 has one Swivel pin 5 on which in the axial direction of the first Telescopic arms 3 fixed and rotatable about this a swivel bushing 6 of a rotating part 7 is mounted.
a swivel bushing 6 of a rotating part 7 is mounted.
the first telescopic arm 3 is the rotating part 7 or its swivel bushing 6 by means of one only indicated in FIG Locking device 8 fixable.
One end of the second telescopic arm 10 is telescopic or displaceable within the square sleeve 9 added. Can be in different positions one end of the second telescopic arm 10 by means of a locking screw 11 fixed in the square sleeve 9 of the rotating part 7 become.
the first telescopic arm 3, the second telescopic arm 10 and that between the first telescopic arm 3 and the second telescopic arm 10 provided rotating part 7 form a positioning device for one restraint part 12 of the restraint device, the other End of the second telescopic arm 10 in a suitable manner is appropriate.
this Retaining part 12 guide rollers 13 for the high pressure line of the heat exchanger high-pressure cleaning device, through through which this high pressure line in one in the figures Extends the pipe of the heat exchanger, not shown, at the free end of the high-pressure line the one mentioned at the beginning Nozzle, probe or the like the heat exchanger high-pressure cleaning device is arranged. If this nozzle comes out, Probe or the like the tube of the heat exchanger is replaced by a Retention funnel 14 prevents that so close to the pipe level the heat exchanger is arranged so that said nozzle, Probe or the like in the event of any leakage from the pipe of the Heat exchanger is forced into the retention funnel 14 and is spatially fixed there.
the distance between the tube surface of the heat exchanger and the retention funnel 14 of the retention part 12 is by appropriate Positioning of the first telescopic arm 3 in relation on the flange connection clamp fixed to the heat exchanger 1 or its square sleeve 2 adjustable.
the retention part 12 can by rotating the second telescopic arm 10 in with respect to the pivot pin 5 of the first telescopic arm 3 and by longitudinally displacing one end of the second telescopic arm 10 inside the square sleeve 9 of the rotating part 7 can be assigned to each tube of the heat exchanger.
An embodiment of the invention shown in Figure 2 Retention device comes especially when cleaning of pipes not shown in Figure 2 for Commitment.
the restraint device has a holding device in the form of a pipe connector 15, by means of which Retaining device can be fixed to a pipe to be cleaned is.
the pipe connector 15 has square sleeves 16, 17, of those in the embodiment shown in Figure 2 Square sleeve 16 for receiving one end of the first telescopic arm 3 serves the restraint.
the pipe connection clamp 15 can alternatively be the other Square sleeve 17 for receiving one end of the first Serve telescopic arm 3.
One end of the telescopic arm can be in both square sleeves 16, 17 3 in any position using locking screws 18, 19 can be fixed.
the first telescopic arm 3 has one Cross sleeve 20, which has a square cross section and in which one end of the second telescopic arm can be moved or is telescopic and fixable.
Locking screw 21 For fixation one end of the second telescopic arm 10 is used Locking screw 21.
a retaining plate 22 has a diameter larger than that Diameter of the pipe to be cleaned.
the retention plate 22 by adjusting the first telescopic arm 3 with respect to the pipe connection clamp arranged spatially fixed on the pipe 15 so close to the pipe opening that the nozzle, probe or the like. the pipe high pressure cleaning device can never emerge from the pipe.
