A coupling device for mounting transformers and the method for their use

BE2017 / 0065

Technical field

The present invention relates to the field of plant construction, in particular a coupling device for attaching transformers and the method for their use.

Technical background

In systems such as workshops, electrical devices such as transformers are usually housed in boxes and are easier to maintain and maintain. When installing the transformers in such boxes, crane systems and elastic steel cables are used due to the relatively high weight. There is always a need to position the transformers safely and precisely when they are lowered in the intended place in the box. Since the transformer is usually heavy, this is often very difficult and there is a risk of accidents in which personnel could be injured and machinery could be damaged.

Content of the invention

The present invention is therefore based on the object of specifying a coupling device for attaching transformers and the method for using them, in which the disadvantages in the prior art have been eliminated.

As for the device of the present invention, this is solved by the following technical concept. The coupling device according to the invention is intended to bend and dock an electrical transformer when it is mounted in a box, the cross section of which is square, in the intended location. It comprises a guide set, a coupling system, which is firmly connected to the transformer via a fastening element. The guide set includes four guide rods attached to the four corner plates provided in the corners of the box. Each guide rod has a swivel arm, which is connected to the respective corner plate via a hinge point, and a hook section, which is bent upwards and outwards, and the angle to the swivel arm is less than 90 °. The coupling system comprises a square and frame-shaped roller carrier which rotatably carries a contact roller on each side. Furthermore, the coupling system has a main plate which is surrounded by the roller support and is firmly connected to it. The upper side of the main plate is connected to the cable of the crane system and the lower side of the main plate is connected to the transformer via a fastening element. The upper ends of the hook sections each point into the upper corners of the box. The contact rollers are designed to come into contact with the hook sections when the transformer is lowered. Each touch roller includes a rotatable outer tube that can roll on the hook portion. Furthermore, each contact roller has an inner tube which is not rotatable but can slide in the axial direction on the slide rail of the roller carrier. The inner tube is connected on both sides with adjustment bolts, which are each connected to an adjustment spring. The adjustment springs are housed in the cavity of the respective side of the roller carrier. Therefore, each contact roller can slide on its side of the roller carrier in the axial direction. The interplay of hook sections and contact rollers allows the transformer to be safely and precisely towed and docked to the intended location in the box when it is lowered. A base area is attached to the bottom of the transformer, which has snap-in grooves on both sides for holding the transformer. A cavity is provided at the bottom of the box, which has a guide rail on its upper side. A threaded shaft 903, which consists of the first shaft section and the second shaft section, is mounted in the cavity. Both shaft sections have opposite threads and are each connected to a snap hook. The snap-in hooks run through the guide rail and can snap into the snap-in grooves to hold the transformer in place. The snap-in hooks each have a slider in their section located between the guide rail and the threaded shaft. A drive motor is attached to the side wall of the box, which is closer to the second shaft section, which drives the threaded shaft and thus the snap-in hooks so that the latter snap into the snap-in grooves and hold the transformer. The drive motor has a set on its side facing away from the cavity

BE2017 / 0065

Batteries on. The battery batteries are electrically connected to the drive motor and serve as an emergency power supply in the event of a power failure.

The method for using the coupling device according to the invention proceeds as follows: In the initial phase, the guide rods are in the folded-up state. If, when the transformer is lowered, it reaches a height level that is lower than the corner plates, with the coupling system still above the covered level of the corner plates, the swivel arms are swung out in the horizontal direction

When the transformer is lowered, the first contact roller will come into contact with the hook section corresponding to its side during the slight oscillating movement of the transformer. In the further process, all other contact rollers will also come into contact with the respective hook sections. The interaction of the contact rollers and hook sections makes this

Vibration of the transformer is absorbed during lowering and allows gentle guidance to the intended location. Since each contact roller can also slide in the axial direction on the roller carrier, the first contact point between the respective hook section and the contact roller does not have to be exactly the middle of the contact roller. The contact point is automatically adjusted and centered by the counteraction of the next adjacent contact roller and with the help of the adjustment springs and adjustment bolts.

Embodiment

An exemplary embodiment of the present invention is explained in more detail below with reference to the drawing.

1 to 4 show, the coupling device according to the invention is intended to bend and dock an electrical transformer 1 when it is mounted in a box 9, the cross section of which is square in shape, at the intended location. It comprises a guide set 91, a coupling system 3, which is firmly connected to the transformer 1 via a fastening element 30. The guide set 91 includes four guide rods attached to the four corner plates 913 provided in the corners of the box 9. Each guide rod has a swivel arm 911, which is connected to the respective corner plate 913 via a hinge point 914, and a hook section 912, which is bent upwards and outwards, and the angle to the swivel arm is less than 90 °. The coupling system 3 comprises a square and frame-shaped roller carrier 32 which rotatably carries a contact roller 33 on each side. Furthermore, the coupling system 3 has a main plate 31 which is surrounded by the roller carrier 32 and is firmly connected to the latter. The upper side of the main plate 31 is connected to the cable of the crane system and the lower side of the main plate 31 is connected to the transformer 1 via a fastening element 30. The upper ends of the hook sections 912 each point into the upper corners of the box 9. The contact rollers 33 are designed to come into contact with the hook sections 912 when the transformer 1 is lowered. Each touch roller 33 includes a rotatable outer tube 331 that can roll on the hook portion 912. Furthermore, each contact roller 33 has an inner tube 332, which is not rotatable but can slide in the axial direction on the slide rail 321 of the roller carrier 32. The inner tube 332 is connected on both sides to adjustment bolts 3321, which are each connected to an adjustment spring 322. The adjustment springs 322 are accommodated in the cavity of the respective side of the roller carrier 32. Therefore, each touch roller 33 can slide on its side of the roller support 32 in the axial direction. Due to the interaction of hook sections 912 and contact rollers 33, the transformer 1 can be safely and precisely towed and docked to the intended location in the box 9 when it is lowered. At the bottom of the transformer 1, a socket area 101 is attached, which has latching grooves 102 on both sides for holding the transformer 1 in place. At the bottom of the box 9, a cavity 905 is provided, which has a guide rail 904 on its upper side. A threaded shaft 903, which consists of the first shaft section 9031 and the second shaft section 9030, is attached in the cavity 905. Both shaft sections have opposite threads and are each connected to a snap-in hook 901. The snap-in hooks 901 lead through the guide rail 904 and can snap into the snap-in grooves 102 in a form-fitting manner to hold the transformer 1 in place. The snap-in hooks 901 each have a slider 902 in their section located between the guide rail 904 and the threaded shaft 903. A drive motor 906 is attached to the side wall of the box 9 which is closer to the second shaft section 9030 and drives the threaded shaft 903 and thus the snap-in hooks 901, so that the latter snap into the snap-in grooves 102 and hold the transformer 1 in place. The drive motor 906 has a set of battery batteries 907 on its side facing away from the cavity 905. The battery batteries 907 are electrically connected to the drive motor 906 and serve as an emergency power supply in the event of a power failure.

The method for using the coupling device according to the invention proceeds as follows: In the initial phase, the guide rods are in the folded-up state. If, when the transformer 1 is lowered, it reaches a height level which is lower than the corner plates 913, the coupling system 3 still being above the covered level of the corner plates 913, the pivot arms 911 are pivoted out in the horizontal direction. When the transformer 1 is lowered further, with the slight oscillating movement of the transformer 1, the first contact roller 33 will come into contact with the hook section 912 corresponding to its side. In the further process, all other contact rollers 33 will also come into contact with the respective hook sections 912. The interaction of the contact rollers 33 and the hook sections 912 absorbs the swinging of the transformer 1 during the lowering and enables smooth guidance to the intended location. Since each contact roller 33 can also slide on the roller carrier 32 in the axial direction, the first contact point must be between the respective one
