Description

The utility model relates to the construction industry and can be used in industrial and residential buildings and structures as a device for opening and closing swing gates.

A swing gate drive is known. (Pat. 80 181 Russian Federation, IPC E05F 15/12 Swing gate drive / S. A. Osipov, N. I. Didenko; No. 200811195/22; filed. 28.03.2008; publ. 27.01.2009. - 5 p. ), containing a reversible motor, a gearbox, a mechanism for transmitting force to the leaf, a lever with a finger interacting with a guide installed on the gate leaf. The mechanism contains a planetary gearbox and a system for limiting the swing angle of the leaf by means of electromagnets. However, from the structural point of view, the drive mechanism is a gear-link mechanism, and the link part of the drive is, in essence, a kind of rocker mechanism.

The disadvantage of this mechanism in this design is the inevitable contamination of the guide, which leads to a decrease in the reliability of the mechanism. In addition, the presence of a multi-link gearbox between the reversible electric motor and a linkage mechanism complicates the overall design and increases the cost of the product.

The closest in technical essence to the claimed utility model is the device of swing gates (Pat. 112 248 Russian Federation, IPC E05F 15/10 The device of swing gates / AD Kasyanov, KE Mirolyubov, AI Ryzhenko; No. 2011123861 / 12; filed 10.06.2011; publ. 10.01.2012., Bulletin No. 1. - 4 p.) The device contains leaves hinged in a fixed element of the gate opening, a drive for each leaf, containing a reversible electric motor rigidly connected to a gearbox, the body of which is rigidly connected to the flap, a torque transmission mechanism, which is a driveshaft, rigidly connected at one end to the rack, the other to the output shaft of the gearbox, located coaxially with the hinge axes on which the flaps are fixed.

In this case, as shown in FIG. 1 and FIG. 2, the hinges on which the gate leaves are supported are kinematic connections made in the form of bearing assemblies, including pins. The pin of the lower joint absorbs and transmits the moment from the propeller shaft to the rack. Therefore, the finger is a critical part of the device, in the design of which it is necessary to calculate the strength, in particular, torsion and the selection of the appropriate material. The mechanism for transmitting torque to the rack includes a cardan shaft and a gearbox with a reversible electric motor. The reversible electric motor is rigidly connected to the gate leaf by means of a reducer. The mechanism with a reversible electric motor is located along an axis passing through the hinges on which the sash rests. The place in a number of gate designs is difficult to access. It is almost impossible to change the location of the sash drive mechanism. Therefore, maintenance of the entire device is inconvenient. When the sash is decelerated by external forces, for example, when foreign objects enter the sash movement zone, the reversing motor stops. Therefore, it may fail.

The technical result of the utility model is to improve the convenience of maintenance and the reliability of its operation.

The specified technical result is achieved in that the swing gate device, including one or two leaves, hinged on the rack, and a drive for opening and closing each leaf, including a reversible electric motor, the body of which is rigidly connected to the leaf, according to the utility model it contains a rotor , the axis of rotation of which is not perpendicular to the axis of rotation of the leaf, connected to the output shaft of the reversible electric motor and connected kinematically with the leaf of the gate.

The presence of a rotor kinematically connected to the leaf, for example, by means of bearings installed on the leaf, and connected to a reversible electric motor, the body of which is rigidly connected to the same leaf, leads to the fact that when the engine is turned on, the rotor starts to rotate. In this case, inertial forces arise that act on the shaft of the reversible electric motor from the side of the rotor, as well as forces of aerodynamic resistance to the rotation of the rotor, which are also transmitted to the shaft of the reversible electric motor. As a result of overcoming these forces in the reversible electric motor, a reactive force moment arises, acting on its body. The reactive power moment is transmitted to the leaf, on which the body of the reversible electric motor is rigidly fixed. Since the axis of rotation of the rotor is not perpendicular to the axis of rotation of the sash, there is always a projection of the reactive force moment onto the axis of rotation of the sash, which is not zero and which imparts rotational motion to the sash. The ideal option for installing the rotor will be the case in which the axis of its rotation will be parallel to the axis of rotation of the sash. Then the magnitude of the projection of the reactive power moment on the axis of rotation of the leaf will be equal to the magnitude of the reactive moment itself. The rotor can be connected to the output shaft of the reversible electric motor either rigidly or kinematically, by any known method, or rigidly mounted directly on the output shaft. In the case of a rigid rotor landing on the output shaft of the reversible electric motor, the kinematic connection of the rotor and the gate leaf will be carried out using the bearing assemblies of the reversible electric motor itself. Since the reactive moment acting from the side of the reversible motor housing on the leaf does not depend on the place of its attachment to the leaf, both the reversible electric motor and the rotor can be installed in any convenient place of the leaf. In addition, when the leaf movement stops, for example, when a foreign object enters the gate leaf, the reversible electric motor does not stop, but continues to work without overload, transferring energy to the rotating rotor, which increases the reliability of the entire device.

Thus, the entire set of features of the utility model allows achieving the claimed technical result - increasing the convenience of maintenance and reliability of the device.

The utility model is illustrated by drawings.

FIG. 1 shows the diagrams of the device. Options:

a) a scheme with a rigid connection of the output shaft of a reversible electric motor with a rotor mounted by means of hinges on the sash;

b) a diagram with a kinematic connection of the shaft of a reversible electric motor with a rotor, mounted by means of hinges on the sash;

c) a circuit with a rotor mounted directly on the output shaft of the reversible electric motor;

d) a diagram with a rigid connection of the output shaft of a reversible electric motor with a rotor mounted by means of hinges on the sash, the axis of which is parallel to the axis of rotation of the sash.

The device contains a reversible electric motor 1, rigidly fixed on the gate leaf 2, which is connected to the post 3 by hinges 4, connected to the rotor 5 mounted on the gate leaf by means of hinges so that its axis is not perpendicular to the axis of rotation of the gate 2, and:

a) the rotor 5 is rigidly connected to the reversible electric motor 1 by means of the clutch 6;

b) the rotor 5 is connected to the reversible electric motor 1 by means of the kinematic connection 7;

c) the rotor 5 is rigidly mounted directly on the output shaft of the reversible electric motor 1;

d) - the rotor 5 is installed so that its axis is parallel to the axis of rotation of the sash 2.

The device works as follows.

When the reversible electric motor 1 (Fig. 1, a), rigidly fixed on the gate leaf 2, is operating, the movement from it is transmitted by means of the coupling 6 to the rotor 5. The rotor 5 starts rotational movement. Since it is acted upon by external moments of resistance to its rotation, both from the side of inertia forces and from the side of aerodynamic resistance forces, an equal and opposite reactive force moment arises, acting from the side of the housing of the reversible electric motor of the engine 1 on the leaf 2. If the projection the reactive power moment on the axis of rotation of the flap 2 passing through the hinges 4 is greater than the moment of resistance to the rotation of the flap 2, then the flap 2 rotates in the direction of the projection of the reactive force moment on the axis of rotation of the flap 2.

When the reversible electric motor 1 (Fig. 1, c) is rigidly fixed on the gate leaf 2, the movement from it is transmitted through the kinematic link 7 to the rotor 5. The rotor 5 starts rotational movement. Since it is acted upon by external moments of resistance to its rotation, both from the side of inertia forces and from the side of aerodynamic resistance forces, an equal and opposite reactive force moment arises, acting from the side of the housing of the reversible electric motor of the engine 1 on the leaf 2. If the projection the reactive power moment on the axis of rotation of the flap 2 passing through the hinges 4 is greater than the moment of resistance to the rotation of the flap 2, then the flap 2 rotates in the direction of the projection of the reactive force moment on the axis of rotation of the flap 2.

When the reversible electric motor 1 (Fig. 1, c), rigidly fixed on the gate leaf 2, is operating, the movement from it is transmitted to the rotor 5 directly from the output shaft of the reversible electric motor 1. The rotor 5 starts rotational movement. Since it is acted upon by external moments of resistance to its rotation, both from the side of inertia forces and from the side of aerodynamic resistance forces, an equal and opposite reactive force moment arises, acting from the side of the housing of the reversible electric motor of the engine 1 on the leaf 2. If the projection the reactive power moment on the axis of rotation of the flap 2 passing through the hinges 4 is greater than the moment of resistance to the rotation of the flap 2, then the flap 2 rotates in the direction of the projection of the reactive force moment on the axis of rotation of the flap 2.

When the reversible electric motor 1 (Fig. 1, d), rigidly attached to the gate leaf 2, is operating, the movement from it is transmitted by means of the coupling 6 to the rotor 5. The rotor 5 starts rotational movement. Since it is acted upon by external moments of resistance to its rotation, both from the side of inertia forces and from the side of aerodynamic resistance forces, an equal and opposite reactive force moment arises, acting from the side of the housing of the reversible electric motor of engine 1 on the leaf 2. If the value the reactive power moment is greater than the moment of the forces of resistance to the rotation of the flap 2, then the flap 2 rotates in the direction of the reactive power moment.
