Definitions

  • the invention relates to a double brake safety device for lifts or stacker cranes (RBG), with a one guide rail for an elevator car encompassing, in the transverse direction to the longitudinal extent of the Guide rail movable console, on the two at opposite sides of the guide rail Brake shoes are provided, one of which is considered active Brake shoe and the other serves as a reaction brake shoe, the active brake shoe over one in both Effective brake eccentric bearing arrangement on the supports as an abutment console.
  • RBG lifts or stacker cranes
  • Such a safety gear is, for example DE 196 06 861 A1. If at the Reaction brake shoe, d. H. the passive brake shoe Soft metal is used and when braking with a Self-locking is worked, so the provisions accordingly usually in the case of non-positive braking the safety gear with the driving force of the elevator motor or with the human hand on the handwheel of the elevator gear release from the catch.
  • braking is over Tungsten carbide brake shoes and especially with structured ones Brake shoes related to self-locking Braking performed, d. H. with so-called positive brake shoes, so is not the power of Motor still has enough power on the handwheel, to release the safety gear from the catch.
  • the Double brake safety catch when catching up as with Catch down with a self-locking effect too safe release of the catch according to the regulations.
  • the single double wedge swing arm can be swiveled in the console stored and thereby enables by simple pivoting a catch in both in the respective catching position Directions. This not only ensures a simple and perfect function, but also a compact design and inexpensive to manufacture. If both brake shoes are designed as a double wedge rocker, the Braking force and the braking effect can be increased significantly.
  • the control edge of one Use of special material Possibility of controlling the control edge independently of the rest
  • To choose material in the way it is for the particular Purpose is appropriate.
  • the pointed edge Tungsten carbide guarantees a safe swing, a soft one Material not.
  • Double wedge rocker over a pitch circular cylinder surface on one Support the counter-circular cylinder surface of the console, whereby the Center of these pitch circle cylindrical surfaces in the swivel axis the double wedge is located. Not all Forces are absorbed on the swivel axis and the Pivot axis can be related to one used pivot pin with a relatively small diameter run, which continues to be a compact design leads.
  • the double brake safety device shown in the figures has a larger, corded outer diameter Spannexzenter SE and a firmly connected to this, d. H. smaller, non-rotatably connected storage eccentric LE. Both Eccentrics rotate on a journal 3 by one Axis of rotation A.
  • the illustrated double brake rod device also has an active brake shoe 2 and one Double wedge arm 6 as a passive reaction brake shoe. This Brake shoes are on both sides of a guide rail 8 of the Arranged elevator. This guide rail is in the figures 8 drawn in dashed lines.
  • the brake shoe 2 as active Brake shoe rests on the LE bearing eccentric.
  • the Double wedge arm 6 is supported as a passive brake shoe Compression springs 7 on a spring abutment 4.
  • the Spring abutment 4 and the journal 3 are on a Console 5 in the form of a box profile firmly together connected.
  • the double wedge rocker 6 is with a central Insert 9 provided, the hard metal with a smooth surface consists. This insert 9 forms a pointed control edge 10. This insert, like the double wedge rocker 6 even in the direction perpendicular to the plane of the drawing Width dimension.
  • FIGS. 2 and 3 Further inserts 11 and 12 form brake shoe inserts, whereby the brake shoe insert 12 for the brake rods down and the brake shoe insert 11 for the brake rods up to Use comes as shown in FIGS. 2 and 3.
  • This Brake shoe inserts preferably have a grooved one Surface, the longitudinal extent of the striations in Braking direction is d. H. in the longitudinal direction of the Guide rail 8. These grooves dig into the material the guide rail 8 and thus lead to a certain Positive locking with the guide rail. This leads to such strong self-locking that only through the wedge effect Safety gear with the driving force of the engine or with the human power on the handwheel of the elevator gear from the Catch can be solved.
  • the double wedge rocker 6 is in a pivot axis 13 by means of of a pin pivoted. This is done by two parallel, lateral support plates 14 on the one hand via screws 15 firmly connected to the double wedge arm 6 and on the other hand, mounted on the pin of the pivot axis 13 are.
  • the storage takes place on a support part 16, which within the console 5 against the force of the springs 7 in Transverse direction to the guide rail 8 is movable.
  • the double wedge rocker 6 is with a Pitch circular surface 17 provided with a central arrangement.
  • This pitch circle cylinder surface is in contact an opposite circular cylindrical surface 18 of the support part 16 and is displaceable compared to this if the Double wedge rocker 6 pivots about the pivot axis 13. Consequently the actual forces occurring when braking are from added this pitch circle cylindrical surfaces.
  • the double wedge arm only on the Hang pivot axis 13.
  • this has disadvantages in that the located in the pivot axis 13 Pins should have a relatively large diameter in such a way that he needs more space between the compression springs 7, which the Compactness of the entire device would impair.
  • the center of the pitch circle cylindrical surfaces 17, 18 is located in the pivot axis 13.
  • the radius R carefully selected so that when catching the brake Pitch circular cylinder surface 17 of the double wedge 6 not slips over the opposite circular cylinder surface 18 and this leaves what is associated with breaking the pivot pin would.
  • the radius R should be in the range of 50 mm and the wedge angle ⁇ should be approximately 5 °.
  • the radius should be less than 60 mm, so that the bolt does not break when this is optimally designed, or to wear out the same. It can also compress the Compression springs 7 occur with the consequence of a change in Coefficient of friction due to the spring compression. This is undesirable since the coefficient of friction during braking is always the must be the same.
  • the radius R should be larger 30 mm, so that the double wedge rocker tilts Contact of the control edge 10 on the guide rail 8 in the desired way occurs.
  • Fig. 1 shows the double brake safety device in their “Exemption” in which neither the double wedge 6 nor the brake shoe 2 still the clamping eccentric SE with the Guide rail 8 are in contact.
  • Fig. 2 shows the double brake safety device in the braking position downwards, in which, when the elevator car is traveling too fast, the tensioning eccentric SE is rotated, for example by the speed limiting device, via mechanical connecting links until the cogged circumferential surface of the tensioning eccentric SE and the double wedge rocker are included the associated brake shoe 2 touch the guide rail 8. From this time onwards, the tensioning eccentric SE takes over the tensioning of the compression springs 7 in that the peripheral surface U SE of the tensioning cylinder SE rolls on the guide rail 8 relative to the fixed guide rail 8 during the movement of the brake safety device.
  • Fig. 3 shows the braking position upwards. It gets through Rotate another in the opposite direction Curve of the cam disc Clamping eccentric for use. Must also catch up the dead center of the bearing eccentric according to the kinematic conditions before the center of rotation of the Storage eccentrics are to ensure a safe "out of catch" guarantee.
  • Double wedge rocker 6 and the support member 16 may, although not shown in the drawings, in the area of the pitch circle cylindrical surface 17 of the Double wedge 6 can be arranged a cross support rib, the in a corresponding groove of the Opposing circular cylindrical surface 18 slides, or vice versa.
  • the double wedge arm 6 thus fulfills this as a compact part Brake catches in both directions and at the same time the possibility a perfect release from the catch, even if the Brake shoes made of hard metal in the material of the Engage the guide rail with a positive fit.
  • the pointed control edge 10 or 10 is not high it is best to use the pointed edge 10 or 10 'forming surfaces 22 of the insert 9 or 9' Grind this one level with the brake shoe insert 11, 12 form.
  • the brake shoe insert digs into that soft rail material. Then forms the respective one Front edge 21 an additional braking element, which the would influence constant friction coefficient. It would be so advantageous to make the angle slightly smaller, so that the pointed control edge is not so deep in it Presses in rail material.
  • both brake shoes 6, d. H. than on both sides of the guide rail 8 are designed as a double wedge rocker.
  • the representation in Fig. 4 corresponds in principle to the representation in Fig. 2, i.e. H. the "braking position DOWN".
  • Both can be used as active brake shoes be formed with an eccentric arrangement according to the Representation in Fig. 1, but with the eccentric in one or can be effective in both directions. It can but also a double wedge rocker passive brake shoe be, with the other brake shoe as the active brake shoe is controlled by an eccentric.
  • damping springs 7 do not necessarily have to be on both sides to be available. It is sufficient if a double wedge swing arm goes through the damper springs 7 is cushioned.
