RU171774U1 - Power drive with controlled force of impact of the tongue on the bell - Google Patents

Abstract

The utility model relates to acoustics, in particular to devices for automatic sounding of bells. A power drive with a controlled force of impact of the tongue against the bell contains an electro-hydraulic servomechanism for sounding bells, a coupling hydraulic cylinder fed by hydraulic fluid through a valve and a high-pressure line with an electrohydraulic pump. The language of the bell is made with the possibility of approaching its skirt by means of two coil springs located between the bell arch and the bracket mounted on the tongue shaft. Between the springs the coupling hydraulic cylinder is pivotally fixed with the bottom toward the arch, and the rod to the bracket. The device also contains a hydraulic cylinder, an electrohydraulic pump, an electric valve, a valve, a receiver, high and low pressure lines, an electrohydro sensor connected to a comparator. Two coil springs are made with the possibility of compression by the hydraulic cylinder to the pressure shock force specified by the regulator, controlled by an electrohydro sensor. The electrohydro sensor is capable of supplying a signal to a comparator, which enables the inclusion of electric fan and shut off the electrohydraulic pump. The technical result is the expansion of the functions of the device by providing the ability to automatically sound the alarm. 2 ill.

Description

A power drive with a controlled force to strike the tongue against the bell.

The proposed utility model relates to church property, in particular to power drives of automation of bell ringing, mainly of large mass and size.

The existing electro-hydraulic servo mechanism for sounding bells I (EGSM) promotes high-quality ringing of large bells, however, attaching it to the base of the bell is not always convenient and not aesthetically pleasing. In addition, the regulation in it of the force of impact of the tongue on the bell is not remote. The elements used for the operation of this EHSM provide compression of the spiral spring by a coupling hydraulic cylinder, fed by hydraulic fluid through the valve and the high-pressure line by the hydraulic pump, and dropping, upon reaching the necessary compression of the spiral spring, this fluid through the electric valve into the receiver by the force of the released spring. The same force pushes the tongue to the bell. Switching the power supply of the electrohydraulic pump and electric fan of this EHS, that is, the compression force of the spring, is carried out mechanically.

The known power drive with fasteners to the bell II, not having a connection with the floor of the bell tower, is applicable to bells up to half a ton. It also does not have remote control of the force of the tongue to strike the bell.

In this power drive with a controlled force of impact of the tongue against the bell, the above disadvantages of the EGSM I and the power drive II, which are its prototype and analogue, are eliminated. Controlling the sound power of a bell is important; for example, to sound the alarm.

Unlike EGSM I, the proposed power drive for aesthetics is mounted between the bell arch and the bracket mounted on the core of the bell tongue. It uses the leverage effect of the third kind. Two spiral springs were used to determine the position of this tongue, with a coupling hydraulic cylinder located between them with elements ensuring its functioning similar to those used in EGSM, with the exception of elements regulating the compression force of the spring. To remotely control the compression force of the springs, an electrohydrogen sensor is used, connected to the high-pressure line and connected to a comparator with a volume control. If the voltage from the electrohydro sensor and the bell sound intensity regulator coincide, the comparator remotely turns on this electric fan and turns off the electrohydraulic pump.

The attached figure 1 (axial section of the bell with a cross along AA) shows the language - 1 bell - 2, close to its skirt with two spiral springs - 3, located between the arch - 4 of this bell and the bracket - 5, mounted on the shaft - 6 languages - 1. Between the springs - 3, the coupling hydraulic cylinder - 7 is pivotally fixed with the bottom toward the roof - 4, and the rod - 8 to the bracket - 5. The hydraulic cylinder - 7 (Fig. 2), in addition to the functional support means - (19) (electric pump - 9, electric fan - 10, valve - 11, receiver - 12, high-pressure lines - 13 and low pressure - 14 ) is equipped with an electrohydro sensor - 15 pressure in the trunk - 13 connected to the comparator - 16. To remotely control the force of the tongue blow - 1 about the bell skirt - 2, it is necessary to set the controlled voltage on the comparator - 16 as the impact force regulator - 17, corresponding to the voltage provided by the electrohydrometer - 15. When these voltages coincide, the comparator turns on the electric fan - 10 and turns off the electric pump - 9, from which the hydraulic pressure is removed on the coil springs - 3, which, when unclenched, push through ronshteyn - 5 tongue - 1. The upper ends of the springs - 3, the hinged connection of the hydraulic cylinder - 7 and the functional support unit - (19) are mounted on the platform - 18. This platform is pressed to the arch - 4 bells - 2 springs - 3 through the bracket - 5 by force the severity of the tongue - 1.
