Definitions

• the invention relates to a handle for a housing for a portable X-ray device.
• portable X-ray devices are known that can be worn by one or two people and thus can be used outdoors. For example, pipes for cracks or the welds connecting them are checked for their quality.
• portable X-ray devices such as, for example, the model Y. XPO 225 of the applicant, have a metal housing which is substantially rotationally symmetrical about its longitudinal axis - except for an X-ray exit window and connections for, for example, an external power supply.
• the respective diameter of the housing is variable, depending on which parts are housed in it at which point.
• a support ring is mounted, which is essentially formed like a steering wheel of a motor vehicle and identifies a circular spar on which the X-ray machine can be well held by the person carrying it.
• the known portable X-ray machines have the disadvantage that they must be raised to spend between two successive examination points of the persons carrying them and at the new location where the next examination point is to be discontinued.
• the object of the invention is therefore to design a handle for such a housing in such a way for a portable X-ray machine, that a transfer from a pickup point to another pickup point is more easily possible.
• a handle for a housing for a portable X-ray device having the features of patent claim 1. Characterized in that the holding part of the handle is connected to a bearing device in which two spaced-apart wheels are arranged on an axis, the entire X-ray device, on which a handle according to the invention is mounted, no longer be lifted from the ground or the object to be examined, to move it from one pickup point to another, but it can be pulled by the wheels. This is much less effort than lifting and moving.
• the movement is possible because the wheels protrude beyond the contour of the main body, so that the housing when moving over a surface - at least if it does not have too large steps - does not sit, but the wheels always represent the most outermost part of the overall device , Since the known portable X-ray devices already have a handle on the housing - regularly even at each end one, no additional element to the housing must be attached, but this can be realized by an integration in the already existing handle or the present Hangriffe ,
• a fixing device for fixing the wheels is formed relative to the bearing device. This ensures that the x-ray unit can be fixed in position during a recording (if it is not on a sloping ground).
• all known locking devices can be used, for example, a blockage by engagement of pins in holes in the wheels or by brake shoes that engage the wheels (as in disc brakes). Since the Those skilled in such embodiments are known and according to the invention does not depend on their specific design, it is omitted to provide more examples for this purpose with an accurate embodiment.
• a further advantageous development of the invention provides that the fixing device has a fixing handle projecting beyond the bearing device.
• a fixing handle By such a fixing handle, it is possible in a particularly simple manner to effect the setting of the wheels. In the case of such an embodiment, this can usually even be done with just a single hand, so that the x-ray device can be held in place with the other hand at the same time. A single person is enough for that.
• a further advantageous development of the invention provides that the recess between the two wheels is circular arc-shaped.
• the bearing device can very advantageously be placed on a tubular body, for example a pipeline pipe.
• the wheels are then still in contact with the tube shell and the intermediate part of the bearing device does not lie on the tube shell. This ensures that the X-ray machine can be moved along the tubular jacket by means of a rolling movement of the wheels and does not have to be pulled with sliding movement on a part of the bearing device, which would be associated with significantly more force and possibly damage the Röh- ren mantels. It is preferred if the recess does not reach to the axis.
• the recess is directed to the through-hole to be examined with the portable X-ray apparatus.
• the tubular objects can be tuned. This means that with smaller tube diameters the circular arc-shaped recess cuts deeper in the direction of the axis of the wheels than with larger diameters of tubular objects to be tested.
• the circular arc-shaped recess cuts deeper in the direction of the axis of the wheels than with larger diameters of tubular objects to be tested.
• tubular objects under investigation with very small diameters - then it makes sense to place the wheels closer to each other or these larger size to dimension - or be examined with a larger diameter.
• a further advantageous embodiment of the invention provides that the holding part is designed as a support ring. This makes it possible that not only between two pickup points a particularly good movement of the X-ray device can take place, but also a good carry-over to the object to be examined or carry away from the object to be examined after completion of the investigation is possible.
• the X-ray machine can also be carried over uneven ground to a vehicle, where it can then be taken away to its location at the company that uses it.
• a further advantageous embodiment of the invention provides that the holding part is formed in a plane. This facilitates the gripping of the handle, as this always leads to the same grip level, regardless of the position of the portable X-ray apparatus on which the handle is located.
• a further advantageous embodiment of the invention provides that the handle is formed symmetrically to a plane of symmetry, which is perpendicular to the plane and the two wheels have the same distance to her. That's it portable X-ray device on which the handle is arranged, centrally disposed on a tubular body to be examined and lateral slipping on the body to be tested is difficult.
• a further advantageous development of the invention provides that the bearing part is not in the plane, and the axis is parallel to the plane. This makes it easier to move the portable X-ray apparatus on which the handle is arranged from one point of the tubular body to be examined to another position of the same body, since, in particular when unilaterally lifting, rolling along in one of two movements that follow the hand Both ends of the housing of the portable X-ray device are attached, is ensured.
• a further advantageous embodiment of the invention provides that the handle is mounted on a housing for a portable X-ray machine with a longitudinal axis and a perpendicular to the largest diameter, wherein the axis is aligned perpendicular to the longitudinal axis and the wheels in a projection along the longitudinal axis at least partially protrude beyond the housing at the largest diameter.
• the axis is aligned perpendicular to the longitudinal axis and thus substantially parallel to the diameter of the housing, the movement along the longitudinal axis can be performed without additional force perpendicular to the longitudinal axis.
• a significantly simpler method of the x-ray device compared to wearing the x-ray device can thus take place.
• a further advantageous development of the invention provides that the wheels are at the same distance from the longitudinal axis. ben. This ensures that a tilting of the X-ray device during the process as in a only one-sided arrangement of the wheels with respect to the longitudinal axis is prevented. This greatly facilitates the movement of the X-ray machine from one pick-up point to another. It is clear to a person skilled in the art that even a slight deviation of the distances between the wheels and the longitudinal axis has the same effect, and thus the effect according to the invention is also achieved at essentially the same distance.
• a further advantageous embodiment of the invention provides that the handle is connected to a first end of the housing with this. This ensures on the one hand that no additional element to the housing of the portable X-ray device must be installed, since the handle is already present anyway. On the other hand, such a handle is always located at one end of the housing, so that by simply grabbing at the other end of the housing to which a second handle is already regularly mounted, the rolling pulling or sliding movement between two receiving points in simple Way can be done by a single person. This is similar to a roller case having at its one lower end two rollers and at its opposite upper end a handle for pulling. Characterized in that at the same time a second inventive handle is connected at a second end of the housing with this, the movement of the X-ray device is further simplified.
• a further advantageous embodiment of the invention provides that the recesses of the two bearing devices of the two handles in the direction of the longitudinal axis are congruent.

• the first bearing device 10 is connected to the first end 2 of the housing 1 via two connecting straps 16 (only one stylized one can be seen - the specific embodiment can be seen in FIGS. 2 to 7). This is a detachable connection, for example by screws. However, since the manner of attachment of the connection tabs 16 to the housing 1 is not essential to the invention and is well known to the person skilled in the art, it will not be discussed in more detail below.

• the Festlegevor- direction is operated in the embodiment by a Festlegehandgriff 15, which protrudes over the first bearing device 10 toward the center of the first handle 17 inwardly.
• the two wheels 12, 13 are spaced apart from each other and have the same distance to the longitudinal axis 4 of the housing 1 (not shown in Figure 2). This has the consequence that the longitudinal axis 4 of the housing 1 is arranged after placing the first bearing device 10 on the tube 30 centrally above the longitudinal axis of the tube 30. Thereby, a tilting of the X-ray device on the tube 30 compared to an arrangement of the wheels 12, 13, in which the second wheel 13 would be arranged, for example, directly on the connecting line between the longitudinal axis 4 of the housing 1 and the longitudinal axis of the tube 30 is reduced.

• the surface of the tube 30 is protected in a move, since there is no rubbing, as in a sliding movement of the first bearing device 10.
