Definitions

  • Control cabinet for an electrical switchgear with one door
  • the invention relates to a switchgear cabinet for an electrical switchgear assembly with a door which is movable with respect to a switchgear cabinet frame and which has a door frame which gives the door mechanical stability and a door leaf arranged on the door frame.
  • control cabinet is known for example from the published patent application DE 43 12 025 AI.
  • the control cabinet there has a door which is pivotally mounted on the control cabinet by means of hinges.
  • the pivotally mounted door can be moved by a lifting mechanism from a lowered locking position to a raised pivoting position and from the raised pivoting position to the lowered locking position.
  • interlocking locking elements engage with one another and lock the door.
  • the door has favorable mechanical properties with regard to the forces acting on it.
  • the present invention has for its object to design a control cabinet of the type mentioned in such a way that its function is improved with a simplified construction of the door.
  • the object is achieved in a control cabinet of the type mentioned at the outset in that the door leaf can be moved relative to the door frame and the door leaf is assigned first locking elements, which are locked with second locking elements assigned to the control cabinet frame the movability of the door leaf can be locked and unlocked against the control cabinet frame.
  • the door leaf can be moved relative to the control cabinet frame when the door frame is stationary in the closed position of the door.
  • Such a construction advantageously avoids overlapping locking movements and opening movements of the door.
  • the door After the door has been unlocked by the movement of the door leaf in relation to the control cabinet frame, the door can be opened, for example, by pivoting the door frame. Opening the door and unlocking the door are two movements that take place independently of one another, so that an accidental one
  • first and the second locking elements are each comb-shaped.
  • Comb-like locking elements are easy to manufacture. With a corresponding design of the first and second locking elements, these can be constructed almost identically. With a comb-like design, a relatively large area results in the locked state, on which the locking elements engage. This ensures a high mechanical strength of a lock designed in this way.
  • the first locking elements are arranged on a door edge opposite a hinged door edge.
  • the locking elements can be moved past one another in a favorable manner when the door is pivotally closed or pivotally opened. All of the first and the second locking elements are almost simultaneously in the same relative positions to one another. Problems such as, for example, the swiveling in of individual locking elements in succession are thereby excluded.
  • the door can be locked and locked in a very simple manner in cooperation with the stop means provided for attaching the pivotable door, such as hinges. It can further be provided that the first locking elements are each arranged along two parallel door edges.
  • a gear is assigned to the door, by means of which the relative movement of the door leaf with respect to the door frame is brought about by means of an eccentric which is rotatably mounted on the door frame or the door leaf and which is supported on the other part of the door.
  • the eccentric has at least one end stop which inhibits the mobility of the gear in the end positions. If one assigns an end stop to the eccentric, this inhibits the mobility of the gear in the end positions. An overstroke of the eccentric is thus avoided in a simple manner. At the same time, incorrect operation of the transmission is impossible, since it can only be forced from one of the end positions to the other end position only with a certain movement sequence.
  • the movement of the door leaf can be limited by the eccentric.
  • the eccentric has flats on its running surface. These flats meet corresponding stops, so that movement of the door leaf against the transmission is blocked.
  • a further advantageous embodiment provides that the transmission has a displaceable latch which prevents the attachment of a drive device, in particular a drive lever, to the transmission in one of its positions.
  • a displaceable bolt in a simple manner prevents a drive device, for example a drive lever, from being attached to the transmission. This ensures that unauthorized operation of the gearbox is excluded. Since the attachment of a drive device is already prevented, an otherwise necessary locking device can thus be dispensed with in the transmission itself. Furthermore, it can advantageously be provided that the bolt can be locked in a first position with the aid of a lock.
  • the bolt can be locked in a first position by means of a lock, unauthorized operation of the movable bolt is prevented. Only people with the appropriate authorization are able to unlock the bolt.
  • FIG. 1 shows a view of the door from the inside
  • FIG. 2 shows a perspective view of part of the door
  • FIG. 3 is a perspective view of a part of the gearbox with a lowered door leaf
  • FIG. 4 is a side view of the gearbox
  • FIG. 5 is a top view of the gearbox.
  • FIG. 1 The interior view of a door 1 of a control cabinet 28 for an electrical switchgear assembly shown in FIG. 1 shows a first side member 2 and a second side member 3.
  • the first and the second longitudinal beams 2, 3 are connected to one another at an angle-resistant manner by a first cross beam 4, a second cross beam 5 and a third cross beam 6.
  • the longitudinal beams 2, 3 and the cross beams 4, 5, 6 form the
  • Door frame of the door 1. This door frame produces the necessary mechanical rigidity of the door 1.
  • a plurality of hinges 7a, b, c, d are arranged on the second longitudinal member 3. This crowd kidneys 7a, b, c, d serve to attach the door 1 to a control cabinet frame 29 so that the door 1 can be pivoted.
  • the cross beams 4, 5, 6 essentially have a U-shaped profile.
  • the side members 2, 3 and the cross members 4, 5, 6 are connected by bolts 9a, b, c, d, e, f, g, h, i, k, 1 to each other at an angle-stiffness in such a way that between the side members 2, 3 and the cross beams 4, 5, 6 a space is created perpendicular to the plane of the drawing, in which a door leaf 8 is arranged.
  • the door leaf 8 has elongated holes which are penetrated by the bolts 9a, b, c, d, e, f, g, h, i, j, k, 1, which the door leaf 8 relative to that from the longitudinal beams 2 , 3 and cross beams 4, 5, 6 formed door frame.
  • the cross members 4, 5, 6 have further elongated holes 11a, b, c, d, e, f, through which angularly rigidly connected to the door leaf
  • the door leaf 8 is profiled like a comb. These comb-like profiles represent first locking elements 12a, b. Second locking elements 12c, d are arranged on the control cabinet frame 29. In the floor area, a floor profile 13 is arranged on the door leaf 8.
  • FIGS. 2 and 3 show sections of a region of the door 1 with the first cross member 4.
  • the door leaf 8 is raised relative to the door frame.
  • the door leaf 8 is lowered relative to the door frame.
  • the door leaf is raised and lowered using a gear 14 arranged on the first cross member 4.
  • the first and second longitudinal members 2, 3 and the first cross member 4 can be seen in FIGS. 2 and 3.
  • the movable door leaf 8 is arranged between the longitudinal and transverse beams 2, 3, 4, 5, 6, which are spaced apart but angularly rigid.
  • On the movable door leaf 8 are one first sealing profile 15 and a second sealing profile 16 attached.
  • the movement of the door leaf 8 is guided by bolts 9a, 9b, 9c, 9d which are assigned to the door frame and which penetrate elongated holes in the door leaf 8.
  • the first cross member 4 has further elongated holes 11a, 11b, which are penetrated by bolts which are rigidly connected to the door leaf and which favor the guidance of the door leaf 8.
  • An eccentric 17 is arranged rotatably in the door leaf 8 on the first cross member 4. Via the eccentric 17, the door leaf 8 is supported on a leg 31 of the first cross member 4 perpendicular to the door leaf 8. By rotating the eccentric 17 by 180 °, the door leaf 8 is transferred from its raised position shown in FIG. 2 to the lowered position shown in FIG. 3 and vice versa.
  • the eccentric In order to ensure intrinsically safe storage of the door leaf 8 in the end positions, the eccentric has two approximately parallel bearing surfaces 18a, b. The door leaf 8 rests in these lowered or raised positions on these bearing surfaces 18a, b. With this construction, it is not possible to move the door leaf 8 bypassing the operation of the transmission 14.
  • the bearing surfaces 18a, b of the eccentric 17 block this movement both in the raised and in the lowered state.
  • an end stop 19 is arranged on the side of the eccentric 17.
  • FIG. 4 shows a section of the first cross member 4 in a side view from the inside of the door.
  • the gear 14 shown in FIGS. 2 and 3 is shown in its entirety in FIG.
  • the eccentric 17 is preceded by a cover plate 20 which serves to guide the eccentric 17 and has a cutout 21 in which the laterally arranged end stop 19 of the eccentric 17 can be moved.
  • cover plate 20 and the end Stop 19 of the eccentric 17 ensures that the eccentric 17 can only be moved in the respectively permissible direction of rotation. This prevents the end positions from being exceeded.
  • a latch 22 is provided.
  • This bolt 22 can be moved and locked by means of a lock 23.
  • the lock has a rotatable tongue 24, which moves the bolt 22 along the first cross member 4.
  • the latch 22 is guided on the bolt which is rigidly connected to the door panel 8.
  • the bolt 22 has a recess 25 which is in the unlocked state in the region of the axis of rotation of the eccentric 17. In the locked state of the bolt 22, the area of the axis of rotation of the eccentric 17 is covered by the bolt 22 (as shown in FIG. 4).
  • the layer-like structure of the transmission 14 with the door leaf 8, the first cross member 4, the eccentric 17 and the bolt 22 can be seen in FIG. 5 in a view from above.
  • the eccentric 17 has an Allen key-like recess 26 on the outside of the door 1 in its axis of rotation.
  • a spring-loaded locking pin 27 is arranged in this socket-like recess 26, in this socket-like recess 26, a spring-loaded locking pin 27 is arranged.
  • the locking bolt 27 can be displaced in the direction of the inside of the door, that is to say that an operating lever can be inserted into the socket-like recess 26, for example moved the locking pin 27 into the interior of the cabinet during insertion.
  • This locking bolt 27 is spring-loaded so that it moves back to its starting position after the control lever has been removed. If the latch 22 is in its locking position, it is not possible to move the locking bolt 27 into the interior of the cabinet, since this is blocked by the latch 22.
  • the eccentric 17 cannot be operated from the outside. As an alternative to such a mechanism, it is conceivable to close the hex-like recess 26 of the eccentric 17 by a cover connected to the bolt 22 on the outside of the door.
  • the sequence of an unlocking process of a door 1 according to the invention is to be described below.
  • the starting point is the locked state shown in FIGS. 3 and 4.
  • the door 1 is closed, the door leaf 8 is lowered, the first locking elements 12a, b arranged on the door leaf 8 are in engagement with the second locking elements 12c, d arranged on the control cabinet frame 29.
  • the bolt 22 is moved into an unlocked position in the direction of arrow 30 by a rotary movement of the tongue 24.
  • An actuating lever can then be inserted into the hex-like recess 26 of the eccentric 17.
