Definitions
- the invention relates to an apparatus for moving a measuring device along a pipe. More specifically, the invention relates to an apparatus for moving a measuring device which is used for example to measure the thickness of the pipe.
- a bracelet used, for example, to measure the thickness of the reactor supply pipes (TAR) for nuclear power plants of the CANDU 6 type.
- the bracelet in question is composed of a frame made of aluminum used to retain a flexible collar fitted with fourteen ultrasonic probes.
- the bracelet allows manual inspection of the first and second bent sections of the supply pipes where most of the faults are found.
- this bracelet has the disadvantage that it must be placed manually on the pipe, thus limiting its radius of action to the length of the operator's arm.
- this bracelet does not allow a complete study of the state of wear of the reactor pipes, insofar as it does not allow to collect the necessary information on the thickness of the pipes along sections which are inaccessible to the operator.
- US Patent No. 5,420,427 Shows an apparatus for the inspection of pipes comprising a bracelet equipped with a motorization device for moving the bracelet on a restricted section of the pipe and for moving in a rotary manner sensors arranged around the bracelet.
- the bracelet motorization system along the pipe consists of a threaded rod driven in rotation by a gear coupled to a motor.
- the bracelet is mounted on the threaded rod according to a slider principle and thus moves along the pipe.
- the principle requires that the threaded rod and its support are previously installed on the restricted mobility segment of the bracelet, and is in no way suitable for moving a bracelet along an elbow or in a place inaccessible manually.
- US Patent No. 5,963,030 shows an apparatus for the inspection of a pipe composed of a bracelet which is manually centered and moved along the pipe on rollers.
- US Patent No. 4,375,165 shows a system for the inspection of joints in pipe lines.
- the inspection device is suspended from a rail arranged above the pipe to be inspected.
- None of the above-mentioned devices allow the inspection of pipes along sections of pipe which are bent or that are located in places that are out of the reach of the inspecting operator.
- An object of the present invention is to provide an apparatus for moving a measuring device along a pipe which makes it possible to circumvent the various drawbacks mentioned above.
- the present invention relates to an apparatus for moving a measuring device along a pipe, comprising a strap having two ends provided with a closure means for closing the strap around the pipe; support means for supporting the measuring device relative to the bracelet; at least one drive wheel each having an axis, mounted on the bracelet and oriented to move the bracelet along the pipe; flexible transmission means having an input for receiving a rotational movement and an output for transmitting the rotational movement; gear means mounted on the bracelet for redirecting the rotational movement coming from the output of the flexible transmission means towards the axis of the wheel; and coupling means for coupling the gear means to the axis of the wheel.
- the present invention also relates to an apparatus for moving a measuring strap along a pipe, comprising at least one drive wheel each having an axis, mounted on the strap and oriented to move the strap along the pipe; flexible transmission means having an input for receiving a rotational movement and an output for transmitting the rotational movement; gear means for redirecting the rotational movement coming from the output of the flexible transmission means towards the axis of the wheel; and coupling means for coupling the gear means to the axis of the wheel.
- Figure 1 is a perspective view of a preferred embodiment of the invention
- Figure 2 is a perspective view of part of the embodiment shown in Figure 1;
- Figure 3 is a perspective view of part of the embodiment shown in Figure 1;
- FIG. 4 is a perspective view of part of the embodiment shown in FIG. 1.
- the apparatus is for moving a measuring device along a pipe (not shown).
- the apparatus comprises a bracelet 4 which can be seen more precisely in FIG. 3.
- the bracelet has two ends provided with a closure means for closing the bracelet 4 around the pipe.
- the bracelet comprises two parts 6 and 8 in the form of semicircles.
- the two parts 6 and 8 have first ends connected by a pivot axis 10 and second free ends on which the closure means is provided.
- the pivot axis 10 allows the two parts to open to be installed around the pipe and then close to be fixed around the pipe by the closure means.
- the closure means comprises a hook-shaped element 12 mounted on one of the second ends of the bracelet, and a rod 14 mounted on the other second end and able to cooperate with the hook-shaped element 12 to close the bracelet around the pipe.
- the apparatus also comprises a support means for supporting the measurement device with respect to the bracelet 4.
- a support means for supporting the measurement device can be mounted with respect to the bracelet.
- ultrasonic probes (not shown) similar to those shown in international application No. WO 0196808 (LAVOIE) can be mounted on the body of the bracelet.
- LAVOIE international application No. WO 0196808
- a coupler diffuser 17 is provided to cooperate with the ultrasonic probes.
- the support means for supporting the measurement device therefore preferably comprises, in the present case, a support arm 28 for supporting a part of the measurement device, ie the diffuser for the coupler, relative to the bracelet.
- the apparatus also includes at least one drive wheel.
- Each drive wheel has an axis.
- Each wheel is mounted on the bracelet and oriented to move the bracelet along the pipe.
- several drive wheels are provided and the apparatus also further comprises at least one free wheel oriented in the same way as the drive wheels.
- freewheel means a wheel which is not connected to drive means.
- the freewheels and drive wheels are evenly distributed along the bracelet.
- the drive wheels are grouped into first and second pairs of wheels 18 and 20, and the free wheels are grouped into a third pair of wheels 22.
- Each of the pairs of wheels has its wheels distributed along a longitudinal axis of the pipe as can be seen in Figure 3.
- the pairs of wheels are distributed evenly along the strap.
- each of the drive wheels has a roller shape on which are mounted two tires 24.
- a single drive wheel may be sufficient to drive the bracelet along the pipe.
- the freewheels could be replaced by non-mobile elements which slide along the pipe.
- the apparatus comprises flexible transmission means having an input for receiving a rotational movement and an output for transmitting this rotational movement.
- these flexible transmission means comprise a first flexible primary transmission shaft 26 having an inlet for receiving the rotational movement and an outlet supported by the support arm 28 of the bracelet 4.
- the flexible transmission means comprise also a second flexible primary drive shaft 30 for connecting the output of the first flexible primary drive shaft 26 to gear means.
- the apparatus therefore comprises these gear means which are mounted on the bracelet to redirect the rotational movement coming from the output of the flexible transmission means towards the axes of the drive wheels.
- these gear means comprise first and second gears 32 and 34 for respectively driving the wheels of the first and second pairs of wheels 18 and 20 via means of coupling.
- the first gear 32 has an inlet for receiving the output from the second flexible primary drive shaft 30 and an outlet for driving the second gear 34 by means of a flexible drive shaft 36.
- the apparatus comprises the coupling means mentioned above for coupling the gear means to the axes of the drive wheels.
- These coupling means comprise flexible secondary transmission shafts 40 for driving the first and second pairs of drive wheels 18 and 20.
- the apparatus may further comprise a motor 42 connected to the transmission means to produce the rotational movement.
- the apparatus further comprises a visual inspection means comprising a light 46, a camera 48 and an encoder 44, mounted on a chassis, and a support arm 16 for mounting the chassis relative to the bracelet.
- the visual inspection means allows the operator to inspect the pipe.
- the support arm 16 has a first part fixed to the second gear 34, and a second part on which the chassis of the visual inspection means is fixed.
- the device is designed to move a measuring strap along the pipe.
- the apparatus comprises at least one drive wheel, flexible transmission means for transmitting the rotational movement, gear means for redirecting the rotational movement coming from the flexible transmission means towards the axis of the drive wheel, and coupling means for coupling the gear means to the axis of the drive wheel.
- the apparatus according to the present invention allows move a bracelet in a motorized way along a pipe and even along an elbow of this pipe.
- the first flexible primary drive shaft 26 has a centered position which allows it to be integrated into the umbilical which also contains the coupling supply, the wire for the encoder and the wires for the ultrasonic probes.
- the size of the device is chosen to suit the size of ART to be tested.
- the device is preferably thinned to allow passage through constrained places (e.g. tight or tight spaces).
- the strap closure means can advantageously be operated remotely.
- the tires provide better traction. Instead of tires, the wheels can be made entirely of rubber or other traction-assisting material.
- the free wheels serve as support wheels.
- the motor 42 is an inline motor "floating" in the umbilical, that is to say that the motor is integrated in the umbilical which connects a control and command unit (not illustrated) to the bracelet who depends on it.
- the attachment of the motor 42 to the umbilical sheath which itself is fixed to the bracelet advantageously contributes to the appropriate maintenance of the motor 42 so that it drives efficiently the primary drive shaft 26 without having to be fixed otherwise eg to a structure external to the device.
- Such an assembly allows in particular the motor 42 to follow the movement of the bracelet.
- the wheels are driven by the primary flexible shafts 26 and 30 coupled between the motor and the secondary flexible shafts 40 on each side of the bracelet.
- the encoder 44 is an encoder by proximity detector.
- the diffuser 17 for the coupler is integrated into the assembly. The distance between the diffuser 17 and the collar is constant. As a safety measure, a steel wire can be hung on the bracelet to allow it to be brought back in the event that the device is subject to malfunction.
