- the invention also relates to a drive for the barrier boom of a barrier, comprising a crank mechanism, a motor and transmission parts.
- the invention relates to a drive for the barrier boom of a barrier, the free end is in the closed position of the barrier in an annular closed part recording, comprising a crank gear, a motor and transmission parts.
- Such drives and barriers are known and are preferably used where destruction by vandalism are to be feared. If the tip of the boom is arranged in the closed position of the barrier inside a ring or the like, there is hardly any possibility to be able to open the barrier forcibly.
- the present invention addresses the problem of improving barriers of this type by ensuring a reliable locking of the barrier against inadvertent opening.
- a drive for the barrier boom of a barrier the free end is in a closed position of the barrier in an annularly closed part recording, comprising a crank mechanism, a motor and transmission parts, characterized
- crank gear is formed with a horizontally oriented crankshaft with a sprocket, which is drivable by a chain hoist and the engine by about 180 ° in one and the other direction
- the coupling is articulated to the sprocket and the rocker to the coupling and on the other hand is articulated on the drive-side end of the barrier boom
- the barrier boom can be swiveled by the motor, a drive pinion and a chain from its horizontal position (with the barrier closed) into the vertical position (with the barrier open) and vice versa,
- the barrier boom is mounted at the upper end of a substantially vertically upright column, the lower end of which is pivotally mounted about a horizontal axis,
- a handlebar is articulated, whose other end is articulated on a second sprocket,
- the sprocket can be biased by means of a tension spring and a guided over the sprocket chain so that the handlebar can pivot out of the column from its vertical orientation and that after this pivotal movement and starting from the horizontal alignment of the barrier boom the pivot axis of the barrier boom after directed upward movement can be such that the geometric axis and the top of the barrier boom can remain at practically the same geodetic height when the pivoting operation starts from the horizontal to the vertical orientation of the barrier boom on the motor is switched on.
- a rotatably mounted Kettenradschreibe is used as a crank of a crank mechanism. From this crank disc, the movement is converted via a connecting rod or two connecting rods (coupling) on the pivot lever on the barrier. It is therefore a kind of crank gear as a barrier drive.
- a second embodiment of the invention has a drive for the barrier boom of a barrier, comprising a crank mechanism, a motor and transmission parts, and is characterized
- crank gear is formed with a horizontally oriented crankshaft with a sprocket, which is drivable by a chain hoist and the engine by about 180 ° in one and the other direction
- the coupling is articulated to the sprocket and the rocker to the coupling and on the other hand is articulated on the drive-side end of the barrier boom
- the barrier boom by the engine, a drive pinion and a chain from its horizontal position (with closed barrier) in the vertical position (with open barrier) and vice versa is pivotable, the chain can be driven by a drive pinion on the gear motor and passed over the sprocket is
- a Kettenradschreibe or a sprocket is used as a crank of a crank mechanism, however, in this embodiment, no double locking is sought.
- the tip of the barrier boom is not driven into a recess, but is taken up in a kind of trough. Nevertheless, the barrier boom against vandalism is better protected than known barriers, because of barrier boom ago introduced forcibly exerted forces can not lead to destruction of the drive, because the elements of the drive is engaged with each other or stop, so that, for example, a destruction of the engine or his gear is as good as excluded.
- the individual elements of the drive are combined into independent modules that can be manufactured by themselves and can be replaced separately in case of destruction. It is a drive for the barrier boom of a barrier, the free end of which is received in the closed position of the barrier in an annularly closed part, comprising a crank mechanism, a motor and transmission parts, and is characterized
- crank gear is formed with a horizontally oriented crankshaft with a sprocket, which is drivable by a chain hoist and the engine by about 180 ° in one and the other direction
- the coupling is articulated to the sprocket and the rocker to the coupling and on the other hand is articulated on the drive-side end of the barrier boom
- the barrier boom can be pivoted by the motor, a drive pinion and a chain from its horizontal position (with the barrier closed) into the vertical position (with the barrier open) and vice versa, these elements belonging to the first module of the drive,
- the barrier boom is mounted at the upper end of a substantially vertically upright column, the lower end of which is pivotally mounted about a horizontal axis,
- the sprocket can be biased by means of a tension spring and a chain guided over the sprocket so that the handlebar can swing the column out of its vertical orientation, these elements belonging to the third module and that after this pivotal movement and starting from the horizontal orientation of the barrier boom the swing arm of the pivot axis of the barrier boom may impart an upward movement such that the geometric axis and the top of the barrier boom may remain at substantially the same geodetic height as the pivoting operation, starting from the horizontal to the vertical orientation of the barrier boom Engine starts.
- the one module of such a drive is essentially the drive column with the parts attached thereto.
- the drive column can be hinged or fastened to the floor and is already equipped with the bearing parts for the barrier boom located in the upper area.
- Another module could be the drive block, that is, he knows the drive console with the engine, the chain guide and the essential parts of the crank mechanism.
- Another module is the suspension of the second chain with the spring.
- This modular design has the advantage that in case of damage of a part cooperating elements can be exchanged in blocks, where, as in the first assembly, the individual modules with their interacting elements only need to be connected.
- the embodiments of the drive according to the invention with double locking have in common that here a special movement of the barrier boom is brought about. This allows the top of the cabinet can be retracted by a few inches into a ring or the like and that the movements required for this purpose are derived from the chain tension of the second chain. So relatively complex movements are realized with relatively simple means.
- the link between the drive column and the second sprocket plays a special role.
- this handlebar can be designed as a rod, so in a preferred embodiment of the invention, a rod with pressure sensor is provided here, which responds to a certain load out. A pressure overrun could occur if the barrier tree encountered any obstacle. If the pressure sensor now responds to the correspondingly effective force on the handlebar, the drive can be reversed so that there is no danger There is a risk that the barrier boom can damage or injure vehicles, objects or people.
- a parallel displacement of the boom main shaft is realized transversely to its longitudinal axis on the pivotable column.
- the proper guidance of this parallel displacement of the main boom tree shaft is realized by a remote crank disc or the double connecting rod.
- a linear force guide has been realized centrally within the drive lever kinematics.
- the stepped Kettenradschreibe is designed with an integrated crankshaft function for the double connecting rod to the boom main shaft.
- An automatic chain tensioning device of the drive motor causes a lead or lag control of the parallel displacement of the boom main shaft. Movements of this chain tensioning device generate against a tension element (chain and tension spring) via the traction sheave of the integrated crank mechanism of the pillar and with one end on the pivot lever of the chain tensioning device, the rotation of the traction sheave for pivoting the drive column and thus for parallel displacement of barrier boom main shaft.
- a tension element chain and tension spring
- the fixed and immovably connected to the base plate column of an embodiment of the invention with the integrated crank mechanism is used to move the pivotable drive pillar.
- the crankshaft, the drive pin of the rocker arm, as well as the articulation point of the transmission rod on the pivoting drive column stand on a straight line in the dead center of the crank mechanism.
- the movable pedestal is locked vertically.
- An adjustment can be made via the coupling point of the motor console to the base plate.
- geared motors are currently used which have a clutch in the gearbox. If a special case in barrier operation, so the engine does not work or the barrier is to be opened by hand, this clutch is actuated so that now the barrier mechanism is disconnected from the drive or the drive shaft, and thus a movement of the boom by hand is possible.
- a gear motor can be used which does not have an internal clutch. Instead, a sprocket is initially set to rotate freely on the output shaft of the transmission and connected via a clutch disc to the output shaft of the transmission. If the coupling is separated by a handwheel, for example, the barrier boom can be moved by hand without the motor being used for this or the motor shaft having to be turned. With the help of the hand wheel and the clutch disc, the front side of the output shaft of the transmission and the sprocket are coupled together via grooves and projections. The clutch disc thus acts as a disengageable and disengageable torque transformer.
- FIG. 1 shows a schematic representation of a barrier drive according to the invention in the double-locked position of the barrier boom, that is locked via a crank mechanism and the barrier boom top.
- FIG. 2 shows a schematic representation of a barrier drive according to the invention in a simply locked position of the barrier boom, that is locked only via a crank mechanism.
- FIG 3 shows a schematic representation of a barrier drive according to the invention with open barrier.
- FIG. 4 shows a perspective view of a drive according to the invention, namely from a viewpoint, which lies on the left rear with respect to the illustrations of Figures 1 to 3.
- FIG. 1 which shows the drive mechanism for a barrier in side view, with the horizontally oriented geometric axis or pivot axis or Designated longitudinal axis of the barrier boom.
- the axis or barrier boom 10 In the closed position of the barrier, the axis or barrier boom 10 assumes a horizontal position. In the figures, the free end of the barrier boom is not shown. Only the horizontal pivot axis 9 and the pivot point of the barrier boom can be seen as a point in the plane of the paper. This is the horizontal axis about which the barrier boom 10 can be pivoted out of the position shown in FIGS. 1 and 2 into the opened vertical position (FIG. 3). The opposite layers have been indicated in broken lines in FIGS. 1 and 3.
- the barrier boom 10 is mounted above and below the plane of the paper as viewed in FIG.
- the bearing itself is attached to the upper end of an upwardly directed drive column or column 40.
- the column 40 is substantially tubular, has a geometric axis 301 and is mounted in its lower portion on a plate so that it can perform pivotal movements.
- the geometric axis of the pivoting movement is designated 41, it is aligned horizontally, i. she stands vertically on the paper plane.
- This mounting of the column 40 allows the pivot axis 9 of the barrier boom 10 can perform movements on a circular arc whose radius is given by the distance between the axis 41 of the column 40 and the pivot axis 9 of the barrier boom 10. Purpose and method of performing this pivotal movement will be explained later.
- the barrier boom 10 and its horizontally aligned axis is connected to a control lever 11, which is an angled lever or the so-called rocker of a crank mechanism.
- the rocker 11 is pivotally connected about a pivot axis 60 with two connecting rods or the coupling parts 12 of the crank mechanism, which are identical to each other, so that in Fig. 1, only one of the two parts can be seen.
- the geometric axis of the pivot axis 60 is perpendicular to the plane of the paper.
- the coupling parts 12 have substantially the elongated shape of a lever. They are wound in the lower area and provided with one or more recesses.
- the coupling parts 12 are pivoted on a sprocket 13 about a horizontal axis 61. It is a traction sheave, so a driven disc and at the same time also around the crank of a crank mechanism.
- the sprocket 13 is rotatable about a fixed horizontal axis 131.
- the elements 13, 131, 61, 12, 1 1 and 9 form a crank drive for the pivoting movements of the barrier boom 10, wherein from the 180 ° rotation of the sprocket 13 out the corresponding 90 ° -Schwenkamba the barrier boom 10 are derived.
- the sprocket 13 is not at the same time designed as a crank lever, but merely serves to transmit torque to a shaft on which sits a separate rocker arm whose pivoting movements are used to pivot the turnpike.
- the elements of the crank mechanism according to the invention are arranged symmetrically to a vertical plane in which the pivot axis 9 of the barrier boom moves.
- the sprocket 13 is mounted on the horizontally oriented shaft 131, which in turn is mounted in two side parts 14 of a drive console.
- an endless chain 15 cooperates, which is guided via a stationary mounted sprocket 16, a pivotable sprocket 17, a stationary drive pinion 18 of a geared motor and from there back to the sprocket 13. It will be appreciated that via the drive sprocket 18, the chain 15 can be pulled in one direction and the other, so that the sprocket 13 can perform rotational movements in a clockwise and counterclockwise direction.
- the sprocket 16 is fixedly mounted on the drive column stand 40.
- a pivot lever 19 is articulated, which can perform rotational movements about the axis of the sprocket 16.
- the end of another chain 20 is fixed, wherein the function and arrangement will be described later.
- the sprocket 17 is rotatably mounted about its axis at a certain distance from the pivot axis of the sprocket 16, wherein this Sprocket 17 is movable in space, namely when the pivot lever 19 moves.
- a switch or limit switch is arranged, which can open or close an electrical contact in dependence on the position of the pivot lever 19.
- this position-dependent switch ensures that the power supply to the motor is interrupted, among other things, even when the pivoting operation of the barrier boom 10 has ended and this has been double locked. Double locked because the barrier boom 10 is fixed by its mechanical connection with the crank mechanism and the geared motor and yet to be explained stops.
- a so-called. Non-contact total locking is given because the top of the barrier boom is located inside a recess or a ring.
- a transmission rod 30 is articulated at a pivot point, which in turn is articulated at its free end at 90 to the drive column 40. It can be seen that a rotation of the sprocket 210 in the counterclockwise direction via the transmission rod 30, a force is exerted on the column 40, so that the column 40 performs a pivotal movement about the axis 41 in the counterclockwise direction.
- the two side parts 14 of the so-called. Drive console are brought together at their lower ends and connected to each other, so that a total of a U-shaped drive console is formed.
- the bottom plates 14 of the drive console are fixed (at x3) hinged (x1, x2) It can be seen that the drive console or the side parts 14 can perform pivotal movements, and indeed to an axis x2. It will be described below, which meaning has this pivoting movement.
- Fig. 2 the individual elements of the barrier drive in a so-called simply locked position (the top of the barrier boom has already been led out by a horizontal movement of the ring) and shown in Fig. 3 with open barrier. The mutually corresponding reference numbers have been used.
- the link elements 12, 70 and 14 are designed according to the invention so that they can not only perform the power transmission described in detail, but also take over stop functions.
- the coupling parts 12 this is best seen in Figure 3, in which the coupling parts are in abutment position at 100 with the handlebar 70.
- Figure 1 can then be seen how a corresponding stopper 100 is accomplished with a further recess of the coupling parts 12 and that also with the handlebar 70.
- Fig. 1 shows the closed barrier and in this is the stop position of particular importance to prevent that 10 improper handling of the barrier boom can be caused in the drive.
- FIG. 4 shows a perspective view of the drive.
- the same reference numerals have been used as have been used in Figs. 1 to 3, but with the following exception.
- the barrier is designated 10, in Fig. 1 is 10 for the geometric axis of symmetry of the barrier.
- Fig. 4 the holder of the barrier tree 10 has been clarified, namely by means of a "U" shaped bracket and Klemmverschraubungs kind.
- the bracket is thus connected to the barrier 10 by means of Spannschraubeuren.
- the drive shaft is fastened in a corresponding manner with screw connections to the freely projecting ends of the "U".
- the opening operation starts with the motor being turned on, i. the drive pinion 18 is rotated counterclockwise.
- the cause of this movement is the tensile force of the spring 21, which is effective via the chain 20.
- the sprocket 210 is rotated counterclockwise and the transmission rod 30 is pulled to the left. Since the rod 30 is connected via the pivot point 90 to the pedestal 40, the pedestal 40 performs a pivoting movement about the axis 41 in the counterclockwise direction. This means that the axis 9 of the barrier boom 10 performs a movement on a circular arc.
- This pivoting movement of the column 40 is transmitted via the handlebar 70 and on the side panels or plates 14 of the drive console.
- the handlebar 70 is in fact articulated both on the column 40 at the articulation point 60, and on the axis 131 of the sprocket 13.
- the consequence of this lateral movement of the link 70 is a pivoting of the plates 14 about its pivot axis x2 in the counterclockwise direction.
- the resulting relationships and positions of the individual parts to each other are shown in Fig. 2, and this shows the time at which the actual pivoting process of the pivoting tree begins.
- the rocker 11 exercises such a movement that the barrier boom 10 is initially moved as a result in that the end point 9 and also the tip, not shown, of its geometric longitudinal axis thereby essentially move at the same geodetic height.
- This means that the geometric axis of the barrier boom does not leave its horizontal orientation. This is noticeable in that even the tip of the barrier boom 10, not shown, is actually on the geometric Moves height of the axis of the barrier boom and not about upward or downward position changes exerts, ie, that the barrier boom and in particular its tip performs no pitching movements.
- the further process of opening the barrier now causes the coupling parts 12 to execute downward movements via the sprocket wheel 13 which is now rotating in the counterclockwise direction and that the barrier boom 10 is transferred into the opened position shown in FIG. 3 by these movements.
- This opening process is terminated by a limit switch on the pivot lever 19 indicates this position and shuts off the geared motor.
- the geared motor is controlled such that the drive pinion 18 is rotated clockwise and this movement is transmitted via the chain 15 to the sprocket 13.
- the rotational movement of the sprocket 13 in a clockwise direction is carried out until the coupling parts 12 abut in its lower region at 100 to the stop of the handlebar 70 (Fig. 2).
- This stop layer has been chosen so that the elements 13, 131, 61, 12, 60 and 11 have reached their upper dead center, i. that the geometric axis 131 of the bearing of the disc 13, the pivot axis 61 for the coupling parts 12 and the pivot axis 60 for the rocker 11 lie in a common plane which is inclined slightly to the vertical.
- a signaling contact or pressure-sensitive switch When the barrier boom is held closed by a person or hits an obstacle, a signaling contact or pressure-sensitive switch responds and causes the geared motor to be reversed and the barrier reopens.
- FIG. 1 again represents a kind of double locking the barrier boom 10: Once on the crank gear 13, 131, 61, 12, 60, 11, 9 and the stop 100 between the handlebar 70 and the coupling parts 12, and over the barrier tree tip pushed into the secured area.
- the free end of the boom is in the secure area, d. H. in the interior of a recess, for example a circular ring, which surrounds the barrier boom tip at a small distance, so that even with the greatest vandalistic effort the barrier boom can not be brought out of this position.
- a recess for example a circular ring
