Description of the invention (i) The present invention relates to a safety brake for an elevator drive device with a driving wheel, especially for elevators carrying people or objects . The brakes commonly used in elevator drives are levers or levers that act on the brake shoes. The disadvantage of this type of brake is its large size and high maintenance cost. The task of the present invention is to provide an Anjin brake for an elevator driving device with a driving wheel, which can reduce the size of the structure and reduce the parts, thereby reducing the consumption of working time for manufacturing the elevator driving device, and at the same time improving the brake Reliability. The safety brake of the present invention has the following special features: the brake is an electro-mechanical controlled inner-shoe brake with at least one brake shoe, the brake shoe has two ends, one end of which is installed in the active transmission (or the motor driving the driving wheel) At a fixed pivot point in the bearing end cover, the other end of the brake shoe is placed at a fixed pivot point in the driving wheel. There are at least two compression springs between the fixed point and the other end of the brake shoe. The compression spring presses the brake shoe against the brake working surface in the active transmission (or the end cap of the motor driving the driving wheel). The brake shoe is located in the working area of the electromagnet in the driving wheel. The electromagnet resists at least one compression spring. Its function is to overcome the pressure of the spring when the electromagnet is energized to disengage the brake shoe from the brake working surface. As long as current is applied to the electromagnet, the brake shoe will always remain in this working position. The best solution of the Anjin brake of the present invention is embodied in the features of the subsidiary patent application. The pole of the electromagnet is preferably a ring pole. The electromagnet preferably also includes a yoke (5), the yoke can be used (please read the precautions on the back φ · and then this page) • Packing. Order-Λ This paper size applies to the Chinese National Standard (CNS > A 4 specifications (210 X 297 ?, cent.)-^ ____ B6 V. Description of the invention (2) The parts of the elevator are best used as single-side bearing end caps. The yoke should be annular and placed on the pole of the electromagnet Between the edges, the edges are made flat and a u-shaped groove is made. By making the edges flat, the magnetic resistance of the magnetic circuit in the magnetic interference area can be increased. The u-shaped groove is used to place the annular magnetic pole of the electromagnet. The magnetic pole is best positioned with a flat plate and covered with gold by the flat plate. A compensating magnetic pole can also be provided beside the magnetic pole to form the directional magnetic field of the magnetic pole. It can compensate the magnetic flux in the machine (such as a bearing). The compensation magnetic pole can It is connected in series with the magnetic pole. However, the coupling between the magnetic pole and the compensation magnetic pole can also take other forms. The safety brake of the present invention can also be made into a double-shoe brake, in which the two brake shoes are symmetrically arranged inside the active transmission. Brake shoes It is placed in the working area of the same electromagnet and can be supported at the same fixed point by a spring. Multiple brake shoes can also be set in the active transmission, each of which is equipped with its own magnetic pole (4). Printed by Zhunfang R Industry and Consumer Cooperative (please read the notices on the f page and then f this page) The substantial advantages of the technical solution of the present invention can not only reduce the size of the structure, but also eliminate the need for pulling and maintenance or leverage. The braking process has the greatest reliability, and its brakes should be designed to ensure that the entire elevator can be braked reliably regardless of whether there are multiple brake shoes or one brake shoe, so it becomes a safety brake. The following will be further improved by an embodiment as shown in the attached image The invention is described. The drawings are described as follows: FIG. 1 is a front view of an elevator driving device, in which there is an electro-mechanically controlled inner shoe type safety brake with a partial cross-section at the master and slave wheels. (CNS> A 4 specifications (210 X 297 mm) _ 4-A6 B6 V. Description of the invention (3) The figure is used to show an electromagnetic pole and a compensation of the brake Figure 1 is a side view of an electromechanically controlled inner-hoe brake embodiment, the brake in this example is a double-shoe brake. The elevator drive shown in FIG. 2 is mainly composed of an electric motor 12, an active The wheel 1 is composed of a brake. The brake has a common, fixed shaft 13 that does not transmit torque. The motor 12 is an outer rotor electrode, and the driving wheel 1 is directly mounted on the flange plate of the motor armature. The two hinge points 2 of the brake shoe 3 supporting the brake are located in the driving wheel. An electromagnet composed of an annular magnetic pole 4 is fixed on the yoke 5, and the magnetic core can double as a bearing end cover part of the elevator driving device. The electromagnet The design should ensure that, when energized, the pressure of the compression spring 7 fixed on the fixed fulcrum 6 can be overcome to suck the brake shoe 3. When the power is cut off, the compression spring 7 presses the brake shoe 3 against the brake working surface in the driving wheel 1. The driving wheel is used as a brake valley. A ring-shaped yoke 5 is located between the magnetic poles 4, and its edges are made gentle and formed with u-shaped grooves 8 for positioning the electromagnetic poles 4. The electromagnetic pole 4 is positioned with a flat plate 9 and is completely covered. A compensation magnetic pole 10 is provided beside the magnetic pole 4, which is connected in series with the magnetic pole. The compensation magnetic pole 10 forms a directional compensation magnetic field of the electromagnetic pole 4. ------ · --- „--------- 5 ------ installed ------ " ------ ^ (Please read the f-face first Matters needing attention to write this page again) The paper standard printed by the R and Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is applicable to the Chinese National Standard (CNS) A 4 specifications (210 X 297 mm) -5-
