Description

Technical field

The invention relates to a drive for sliding gates along the restrictive part of the attached claim 1, as well as to a drive device according to the restrictive part of claim 10. In addition, the invention relates to a mounting method for the restrictive part of the attached claim 12. Such a drive, such a drive device and such a mounting method are known from DE 102005058939 B4.

State of the art

Driving devices for sliding gates - for example, sliding gate drives - in most cases have a gear wheel driven by a motor, which engages with a gear rack located on the movable sliding gates.

The following describes the method of mounting such a drive for sliding gates, typical of the prior art. In this case, the installation of the rack is especially difficult, since the rack must be placed on the sliding gate so that it occupies a certain height position on the sliding gate. With precise positioning, the rack is engaged with the teeth of the drive gear with a predetermined clearance. This precise positioning of the rack should be observed along its entire length. To do this, the gear rack is laid on top of the gear wheel, and during installation, the gear wheel is not connected to the engine and therefore has the ability to rotate freely. First, the rack using the receiving device is fixed at the first attachment point. Then the sliding gate with the gear rack is moved so that the next receiving device of the sliding gate stops exactly above the gear. However, for such an installation method, a device must be provided for disconnecting the gear and the engine. It is expensive and feasible only with the help of special designs. On the other hand, gear motors are available as mass-produced on the market, in which the gear wheel is rigidly connected to a self-braking drive mechanism and motor. These inexpensive designs are not applicable in combination with the traditional installation method.

From a patent document DE 102005085939 B4, a sliding gate operator is known which includes an engine, a gear wheel and a gear rack fixed in a design position on a sliding gate. For mounting, the gear wheel is brought into the adjustment position, and then at least one part of the gear tooth region is fitted with a spacer element as an auxiliary mounting element. The spacer element has a sliding surface on its outer diameter, which makes it possible to slide a gear rack over it. In addition, the spacing element is dimensioned so that it compensates for the difference in position between the operating position and the mounting position. After installing the spacing element, the gear rack is put on the sliding surface of the spacing element so that the design position of the gear rack is obtained. Finally, the rack is fixed in the design position on the sliding gate. After fixing, the distance element is removed from the gear and the gear is brought into working position, so that the previously fixed gear rack is engaged with the gear. This method is problematic with respect to monitoring the correct installation of the design position.

Disclosure of invention

The basis of the invention is the task of improving the drive along the restrictive part of paragraph 1 of the claims so that with simple and economical manufacture it becomes possible to more accurately control the correct installation of the design position of the rack.

This problem is solved by a drive with the features of paragraph 1 of the claims. A drive device provided with this drive is the subject of a further independent claim 10. The mounting method performed with such a drive is the subject of yet another independent paragraph 12.

Preferred embodiments of the invention are the subject of the dependent claims.

The invention provides a drive for sliding gates with a drive unit having a gear wheel, driven by an engine, which is designed to mesh with a gear rack fixed on the sliding gate, and is located on a carrier with the ability to move between the working position and the mounting position, and with an auxiliary mounting device for installing and adjusting the rack on the sliding gate, and the auxiliary mounting device has at least one mounting roller lement disposed on the carrier device removably and rotation.

At least one mounting roller element in a preferred embodiment is a mounting gear; but it is also possible to use a roller that rolls along a gear rack.

The drive is preferably made so that during installation it is possible to accurately position the rack in the vertical direction with the help of a support device and thereby control the exact engagement of the rack with the gear, and the mounting roller element, in particular the mounting gear, assumes the role of the main gear wheels. Control can be done either by rotating the gear wheel or by moving the gear rack in the horizontal direction. Due to the implementation of the drive in its preferred embodiment, it is not necessary to integrate into the drive unit for separation, in particular, on the transmission of force between the engine and the gear wheel. The translation of the gear into the working position and the mounting position is possible, for example, by means of a simple linkage. Thanks to this, it is possible to use inexpensive motors and gearboxes available as mass-produced goods to drive.

In addition, the drive has a rigid connection between the engine and the gear. This rigid connection is carried out, in particular, by means of a self-braking drive gear; this causes the positive effect that for sliding gates there is no possibility of moving them by applying force in the axial direction, so that when closed, the sliding gates cannot be opened manually.

The auxiliary mounting device for fixing the rack in the design position preferably has at least two mounting roller elements. As a result, the gear rack cannot warp during installation. In addition, thanks to the use of two mounting roller elements, a smooth movement of the gear rack is achieved during the horizontal movements of the gear rack during installation.

In the preferred case, at least one mounting roller element is made of plastic, preferably molded by injection molding, it is performed as a disposable part. As a result of this, a simple and especially economical production of the mounting roller element is ensured.

The mounting roller element preferably has a protrusion in the form of a rod, such as a bearing shaft, inserted into the through or blind hole of the carrier. Due to this, no additional support elements are required to be manufactured, which, on the one hand, entails an advantage in minimizing costs and, on the other hand, allows mounting of the mounting roller element in a through or blind hole more quickly.

In a further preferred embodiment, it is provided that the gear is surrounded by the gear housing to protect it from external influences, the mounting roller element being mounted outside the gear housing. This gives, on the one hand, the advantage of the protective function during operation and installation and, on the other hand, during installation, it is not necessary to remove the gear housing, since it is possible to directly insert the mounting roller element into the gear housing from the outside.

In a further embodiment, it is provided that the gear housing has wing wings that are beveled on the sides. They serve to receive at least one mounting roller element, and the wings of the housing which are beveled on the sides are preferably made so that the distance between the mounting roller element and the gear wheel is preferably small. As a result of this, it is possible that the differences in height between the mounting roller element and the gear wheel are minimal. In addition, the beveled wings of the housing provide an economical possibility of forming support elements for the mounting roller element. The wings of the body, which are beveled on the sides, are preferably made in such a way that through or through blind holes are made in them without great expense. The above advantages are also significant when using two mounting roller elements.

Through or beveled wings of the housing, through or blind holes are preferably made, which serve to receive mounting roller elements. Through or blind holes are preferably arranged in such a way that with the correct insertion of the mounting roller elements, the required design position of the rack is set.

The drive unit (as a whole) is preferably rotatable between the mounting position and the operating position by means of a lever mechanism. An embodiment with a lever mechanism is a particularly simple construction that makes economical manufacturing possible. In addition, it is possible, by actuating the lever mechanism, to check at any time during installation whether the gear rack is in perfect engagement with the gear.

In a preferred case, at least one mounting roller element is a mounting gear for interacting with a gear rack or a mounting roller for rolling on a gear rack when interacting with it.

In a particularly preferred embodiment, such an arrangement of the mounting roller element on the support device is provided that when the gear is in the mounting position, the design position of the gear rack is set so that the mounting roller element interacts with the gear rack to fix it, and the mounting roller element is placed on the support rotatable to allow the movement of the rack during installation, while the mounting roller element is placed so that the gear the wheel in its working position engages with a gear rack positioned by means of the mounting roller element with a given clearance.

In a further preferred embodiment, there is provided a method of mounting a drive device for a sliding gate, comprising a drive and a gear rack interacting with the drive, on a movable sliding gate by means of an auxiliary mounting device, which serves to position the gear rack in the design position on the sliding gate, using as an auxiliary mounting device mounting roller element.

In a preferred embodiment of the method in which the drive unit has a gear driven to the drive position and the mounting position, the following operations are preferred. First, the gear wheel is brought into the mounting position, which is below the working position of the gear. Then provide at least one mounting roller element, which holds the gear rack in its design position necessary for installation. Then set the design position of the rack on the sliding gate by the interaction of the rack with the mounting roller element. After that, the gear rack is fixed in the design position on the sliding gate, and finally, at least one mounting roller element is removed, and the gear is moved back from the installation position to the working position so that the gear engages with the gear rack.

For mounting the rack, sliding gates are preferably brought into different positions in which different sections of the rack interact with the mounting roller element. Thus, at any time it is possible to check whether the gear rack is exactly in the design position or, perhaps, changes in the position of the gear rack should be made.

The method is preferably applied to a drive device of the kind mentioned above. As a result of this, for the drive of the aforementioned type, it is precisely mounted on the sliding gate.

In a further preferred embodiment, the mounting roller element is inserted into the drive housing. The insertion of the mounting roller element is easier to perform than if it had to be pressed or screwed on.

It is possible by rotating the mounting roller element to conveniently check whether the gear rack is in its design position.

If it is not possible to rotate the mounting roller element when checking the design position of the gear rack, it may be necessary to move the gear rack down until the gear rack interacts with the mounting roller element so that the mounting roller element can rotate when re-checked.

At least one mounting roller element is preferably a mounting gear with which proper engagement is simulated better than with a roller. In particular, a pair of mounting gears is provided that are located on both sides of the main gear.

The implementation of the invention

Figure 1 shows a drive device 10 with a drive 12 and with a gear rack 14.

Toothed rack 14 has several fastening plates with grooves 16 located on its upper side, which are intended to be mounted on sliding gates not shown here in detail.

The drive 12 has a carrier device 17, which contains a gear wheel 30 driven by the motor, whose position relative to the ground is constant. To this end, the drive 12 has a lower housing part 18, an upper housing part 20, and also a gear housing 22 fixed on the front side of the lower housing part 18. In addition, the drive 12 has a drive unit 24, which is located in the lower part 18 of the housing.

The drive unit 24 is described in more detail below based on FIGS. 2 and 3.

The drive unit 24 shown in FIG. 2 has an electric motor 26 which is connected via a flange to a worm gear not shown in detail. The assembly, consisting of an electric motor 26 and a worm gear, is made in the form of a standard part, inexpensive and available as a mass-produced product. The gear wheel 30 is rigidly connected to the worm gear. Further, the drive unit 24 has a lever mechanism 28, which allows by turning it in the vertical direction to translate the gear 30 from the working position to the mounting position and vice versa.

The lever mechanism 28 is described in more detail below based on FIG. The lever mechanism 28 in this embodiment is made with a lever arm 34. An actuator 32 is placed at the end of the lever arm 34. A bearing is formed at the other end of the arm arm 34 with a bearing housing 36. A collar 38 is mounted on the bearing housing 36, which is made in the form of an upper sliding insert.

Figure 4 shows the installation of the drive unit 24 in the lower part 18 of the drive housing 12. In this case, the bearing housing 36 is placed in the sliding liner 42 of the lower housing part 18, and the clamp 38 not shown in Fig. 4 is connected to the liner 42. Further, in the lower of the housing part 18 there is an opening 44 through which the gear 30 protrudes outward. Shown in figure 4, the position of the gear 30 corresponds to its working position. In addition, by means of the lower part 18 of the housing, the drive 12 is placed near the sliding gate and fixed relative to the place, as is known, for example, from patent document DE 102005058939 B4.

Figure 5 shows the mounting position of the gear 30, in which the gear 30 is translated when the mechanism 28 of the lever.

6 and 7 show the drive 12 with the upper part of the housing 20, worn on the lower part 18 of the housing. Figure 6 shows the working position of the gear 30, while figure 7 shows the mounting position of the gear 30.

On Fig and 9 shows the actuator 12 in the operating position and with the gear housing 22 placed in the lower part of the housing 18. The casing 22 of the gear wheel has two beveled wing sides 56 of the casing, in the upper region of which there are through or blind holes 50. In the lower region, the casing 22 of the gear is provided with two openings 52, which are used to fasten the casing 22 of the gear to the lower part 18 of the housing the help of fasteners, made, as shown in this case, in the form of screws 54. In addition, the housing 22 of the gear in the area of the lid has an opening 48 through which the teeth of the gear 30 in its working position protrude outward for the nose gear with gear rack 14 (see, for example, Fig.9 and 14). In the mounting position, the gear 30 is turned down so that it does not protrude from the hole 48 (see, for example, Fig. 11).

10 and 11 show the actuator 12 with an auxiliary mounting device 60. The gear wheel 30 in both figures is in the mounting position. The mounting aid 60 has at least one roller element.

In the example of FIGS. 10 and 11, two roller elements are shown, the roller elements being made here in the form of mounting gears 62. The mounting gears 62 are made of plastic, in particular by injection molding, and are disposable parts. Mounting gears 62 have bearing shafts extending horizontally back from their centers, which are not visible in FIGS. 10 and 11. The bearing shaft is made in the form of a simple pin. With the help of the bearing shafts, the mounting gears 62 are inserted into the through or blind holes 50 of the beveled wings 56 of the housing 56.

Subsequently, on the basis of FIGS. 12 and 13, an embodiment of the method of mounting the drive device 10 on sliding gates not shown in more detail is explained.

The drive 12, more precisely, the lower part 18 of the housing, is fixedly mounted in a suitable place near the sliding gate. The gear wheel 30 using the mechanism 28 of the lever is transferred from its working position to the mounting position. For mounting, at least one roller element is inserted into the gear housing 22. In the embodiment explained here in more detail, two mounting gears 62 are used as roller elements, which are inserted by their bearing shafts into the through or blind holes 50 of the wing wings 56 that are beveled on the sides of the housing. By using two mounting gears 62, skewing of the gear rack 14 during installation is prevented. In addition, the use of two mounting gears 62 provides a more even movement of the gear rack 14 during its movement for the necessary positional changes during installation of the gear rack 14. The gear rack 14 is engaged with the mounting gears 62, as shown in Fig.12 . To check for precise engagement between the mounting gears 62 and the gear rack 14, either the mounting gears 62 can be rotated or the gear rack 14 can be moved horizontally. When positioned accurately, the gear rack 14 moves in the first case or the mounting gears rotate in the second case 62 . If there is no precise engagement between the gear rack 14 and the mounting gears 62, then the gear rack 14 is re-positioned by moving in the vertical direction.

When the gear rack 14 is in the design position necessary for installation, it is possible to fix the gear rack 14 on sliding gates not shown in detail. To do this, through the grooves 16, fixing means are introduced that connect the toothed rack 14 to the sliding gate. After the first groove 16 is connected to the sliding gate, the sliding gate with the gear rack is moved to a certain length so that the nearest groove 16 stops exactly between the two mounting gears 62. The groove located between the two mounting gears 62 is also fixed relative to the sliding gate using fasteners. This sequence of actions is repeated until all the grooves 16 are connected to the sliding gate by means of fixing means.
