Definitions
- the invention relates to a mechanical locking device for electrical switching devices, which serves to ensure the actuation of only one of two switching devices at a time.
- a device of this type is already known (US-A-1 569 713) which is used to lock the tap changer of an electric vehicle with respect to the direction switch.
- a ball serves as the locking element, which is displaceable in an opening of a stationary part which is adapted to its diameter and can in each case partly dip into recesses of counterparts which are connected to the step switch or the direction switch.
- the speed switch can only be operated, d. H. can be moved from its rest position to one of the speed levels when the direction switch is outside its zero position.
- the direction switch can only be moved to its zero position when the speed switch is in the zero position.
- the invention has for its object to provide a locking device working with a ball, which is particularly suitable for vacuum contactors.
- the problem with these switching devices is that the locking device must be effective even with very short relative displacements, because the drive movement has only short distances.
- Such a locking device consists of only a few parts, which are relatively easy to manufacture due to their flat shape or are available as standard parts. It is also easy to connect to the switching devices, since the support bracket offers the possibility of an uncomplicated connection to the support structure of the switching devices and the slides act as canting and actuating elements.
- the balls to be used can be normal steel balls as used for ball bearings.
- the mentioned guide can be realized in an advantageous manner by a locking block of H-shaped cross section, which has two longitudinal beams, each with at least one opening for receiving a connecting member for connecting the locking block to the support bracket, the longitudinal beams being connected by a cross member, which contains the mentioned openings for the first and the second ball.
- An advantageously simple guidance of the two carriages can be achieved in that the actuating arm of the first carriage and the actuating arm of the second carriage are arranged on one side of the connecting part of the H-shaped locking block and that the blocking arm of the first carriage and the blocking arm of the second Carriage are on the other side of the cross member and the operating arm of the first carriage and the locking arm of the second Carriage are aligned with each other, and the locking arm of the first carriage and the actuating arm of the second carriage are also aligned with each other.
- the carriage overlap the cross part of the locking block in a fork-like manner and is guided so that it can be moved in a straight line.
- the locking device operates with as little play as possible in order to ensure the desired safety.
- This property can be promoted by suitable dimensioning of the diameters of the different openings.
- the opening of the locking arm of the first slide can have a smaller diameter than that of the second ball, so that the second ball can only enter the opening of the locking arm of the first slide by a certain distance, while the majority of the second ball in the second opening of the cross part of the locking block remains and thereby prevents movement of the first carriage relative to the cross part.
- the new locking device is particularly suitable for use with vacuum contactors that have a short travel distance for their drive parts.
- Assembling the locking device with the vacuum contactors can preferably be done so that the support bracket of the locking device is connected at its ends to the support structure of a vacuum contactor and that the vacuum contactors are arranged with mutually facing pivotable drive levers, actuating members of the carriage being articulated to the ends of the drive levers.
- the articulated connection because the swivel angle of the drive lever when switching on and off is extremely small.
- FIG. 1 shows a side view of an arrangement with two vacuum contactors and a locking device arranged between the vacuum contactors.
- Figures 2, 3 and 4 show a bracket of a locking device in perpendicular views.
- Figures 5, 6 and 7 show a locking block of a locking device also in three mutually perpendicular views.
- FIGS. 8, 9 and 10 A first carriage of a locking device is again shown in FIGS. 8, 9 and 10 in three views perpendicular to one another.
- FIGS. 11, 12 and 13 a second slide is shown in FIGS. 11, 12 and 13.
- FIGS. 14 and 15 serve to explain the interaction of the slide shown in FIGS. 8, 9 and 10 and 11, 12 and 13 with the locking block according to FIGS. 5, 6 and 7.
- FIG. 14 shows the non-actuated rest position of the parts
- FIG. 15 a blocking position is shown.
- FIG. 1 shows a device arrangement 10 with a first vacuum contactor 12 and a second vacuum contactor 14, each of which comprises a drive lever 16 or 18, which moves depending on the opening and closing of the vacuum contactor.
- the drive parts 16 and 18 can pivot about bearing points 94 and 96 and convert the movement at their connection point with a mechanical locking device 20 into a lateral movement.
- the mechanical locking device 20 comprises a support bracket 22, a cover plate 24, a locking block 26 and first and second slides 28 and 30.
- the locking device has a first ball 32 and a second ball 34.
- FIGS. 2 to 4 show that the support bracket 22 has essentially the shape of a "U", the end parts of the "U” being bent outwards by approximately 90 ° relative to the legs.
- base parts 36 and 38 are formed, which can be provided with holes or openings 40, 42 in order to fasten the support bracket 22 to the frame of the vacuum contactor.
- the bracket also has a number of openings 44 in the central portion at the bottom of the "U".
- the support bracket 22 is preferably made of a metal such as sheet steel or a copper alloy, but it can also be made of another solid and durable material.
- the locking block 26 has a first and a second opening 48 or 50 and a number of further openings 52 which can be made to coincide with the openings 44 of the mounting bracket. These openings have a size and design that is sufficient to accommodate fasteners, e.g. B. bolts or screws.
- the locking block 26 is approximately H-shaped with two upright longitudinal beams 84 and a cross member 54, which has the first and second openings 48 and 50, respectively.
- the longitudinal beams 84 contain openings 52 which are used to connect the locking block 26 to the bracket 22 and the cover plate 24.
- the first opening 48 of the locking block 26 is dimensioned such that the ball 32 can move freely through the opening 48.
- the second opening 50 of the locking block 26 has a diameter such that the second ball 34 can also move freely vertically.
- vertical movement is meant here that the balls can move in a direction parallel to the longitudinal beams 84 of the locking block 26 and in a direction perpendicular to the cross member 54.
- the openings 48 and 50 of the locking block 26 are preferably aligned side by side between the upright members of the H-arrangement, as will be explained in more detail.
- the first carriage 28 has an actuating arm 60 with an opening 62 and a blocking arm 64 with an opening 66.
- the first carriage 28 also has a coupling arm 68 and one or more openings 70 for receiving Screw on as an abutment of one or more springs 72.
- the actuating arm 60 is at a lower height than the locking arm and is located on the opposite part of the vertical part 68.
- the actuating arm 60 and the locking arm 64 are vertically separated by a distance that is slightly larger than the thickness of the cross member 54 of the locking block 26.
- the first carriage 28 can grip the locking block in such a way that the locking arm 64 is above the cross member 54 and the actuating arm 60 is below the cross member 54.
- This construction enables the opening 62 of the actuating arm of the first carriage 28 to receive the first ball 32 through the opening 48 of the locking block 26.
- the opening 62 is a stepped opening with a first one located at a lower height Opening part 86 with a smaller diameter and second opening part 88 arranged at a higher height with a larger diameter than the opening part at the lower height.
- the larger opening portion 88 has a diameter that is larger than the diameter of the first ball 32 so that the carriage 28 can move when the ball 32 rests in the opening 62; this happens when the opening 62 and the opening 48 are aligned. As shown, the larger opening portion 88 is funnel-shaped toward the smaller opening portion 86 to form a ramp.
- the first carriage 28 is displaceable relative to the locking block 26 between a first position in which the opening 62 of the actuating arm 60 and the opening 48 of the locking block 26 are aligned with one another and a second position in which the opening 62 of the actuating arm 60 and the first Opening 48 of the locking block 26 are not aligned.
- the second carriage 30 is constructed similarly, with the exception that the lateral position of the actuating arm 72 and the locking arm 76 are selected so that the actuating arm 72 is aligned with the space which is adjacent to the actuating arm 60 of the first carriage 28 and below of the locking arm 64, while the locking arm 76 is aligned in the space to the side of the locking arm 64 of the first slide 28 and above the actuating arm 60. In this way, the first and the second slide 28 and 30 interlock.
- the second slide 30 has a stepped opening 90 in its actuating arm 74 with a first smaller opening part 92 and a larger, slanted or funnel-like opening part 94.
- a coupling arm 78 the task of which will be explained.
- the second carriage 30 is displaceable between a first position in which the opening 74 of the actuating arm and the opening 50 of the locking block 26 are aligned with one another and a second position in which the opening 74 of the actuating arm and the opening 50 of the locking block 26 are not aligned with one another are.
- the first and second balls 32 and 34 are located substantially in the openings of the first and second carriages and fall into or merely extend into the corresponding openings of the actuating arms. If the parts are properly assembled and aligned in the vacuum contactor, this corresponds to the open position of each vacuum contactor. If the first vacuum contactor 12 is closed, the movable part 16 is displaced by the closing movement, which acts on the first carriage 28 and moves it from the first to the second position. In the first position, the openings are aligned and the balls are at the lowest point. In the second position, the openings are not aligned, which means that the ball is pushed upwards by the funnel-like opening part 88 of the actuating arm 60.
- the ball 32 By the upward movement the ball 32 is caused to protrude over the transverse part 54 of the locking block 26, where it detects the opening 96 of the locking arm 76 of the second slide 30. This prevents the second carriage 30 from moving and consequently prevents the second vacuum contactor 14 from closing. If the second vacuum contactor closes first, the reverse effect occurs. When the second contactor closes first, the first contactor is prevented from closing by the upward movement of the second ball 34 into engagement with the opening 66 of the locking arm 64 of the carriage 28.
- each vacuum contactor 12 or 14 has, in a known manner, a supporting structure 80 which offers a simple possibility for fastening the foot parts 36 and 38 of the supporting bracket 22.
- the coupling arms 68 and 78 of the slides 28 and 30 are articulated to the ends of the drive levers 16 and 18, with very little requirement being imposed on the degree of articulation because the pivot bearings 16 and 18 are relatively far from the coupling arms and the swivel angle of the drive lever is only small.
- FIG. 14 both carriages 28 and 30 are shown together with the transverse part 54 of the locking block 26 in the basic position or in the rest position, which corresponds to the switch-off position of both vacuum contactors 12 and 14.
- FIG. 15 shows a locking position in which the slides 28 and 30 are displaced relative to one another by means of the coupling arms 68 and 78.
- the ball 32 is shifted upwards in FIG. 15, so that it is partially in the opening 48 of the cross member 54 and partially is located in the opening 96 of the locking arm 76.
- the carriage 30 and thus the drive lever 18 are thereby blocked.
- the ball 34 rests unchanged in the larger opening part 94 of the actuating arm 74.
