Description

Linkage distance measuring device of friction coupler of electric switch machine and electric switch machine
Technical Field
The utility model relates to a railway professional equipment field relates to a linkage range unit and electric goat suitable for electric goat with friction coupling.
Background
On the railway, the electric switch machine is the main equipment for railway switch conversion, its main brake device is a friction coupling which is mounted on the brake disk of the main shaft speed reducer of the driving motor, and is a coupling device for protecting the driving motor and absorbing the moment of inertia. Specifically, the structure and the action process of the friction coupling are shown in fig. 1, wherein a friction braking plate 2 is installed on a small outer circle of an inner gear 5 of the speed reducer, a friction plate 1 is arranged on the inner side of the friction braking plate 2, the lower end of the friction braking plate 2 is sleeved on a clamping plate shaft fixed on a speed reducing shell 3, and when the upper end of the friction braking plate 2 is pressed by a bolt spring, the inner gear 5 is fixed by friction, so that under the normal conversion condition, the inner gear 5 gives a reaction force to the outer gear according to the friction force, the outer gear rotates in the swing type motion, an output shaft 7, a main shaft and a locking gear are driven to rotate, and the turnout conversion is driven. When the turnout switch rail is in contact with a barrier and can not be tightly attached, the dynamic friction of the friction plate in the friction coupling ensures that the turnout transmission is separated from the motor, and the driving motor is protected from being damaged in the rotation process. The friction force of the friction coupler needs to be adjusted properly, the driving motor and related parts can be damaged due to over-tightening, the turnout can not be normally driven to switch due to over-loosening, the size of the friction force is adjusted by adjusting the pressure of the spring 4, and the normal work of the friction coupler is ensured.
The main current measurement methods for the dynamic friction resistance of the friction coupling of an electric switch machine include:
1) Measured with the triboelectric current: that is, when the electric switch machine switches the points, the points are prevented from reaching a predetermined position, the operating current for rotating the drive motor of the electric switch machine at that time is determined, and the dynamic frictional resistance of the friction coupling is indirectly estimated from the operating current. However, this measurement method has a large error and does not truly reflect the frictional resistance of the friction coupling at rest.
2) Measured with the replacement action lever pin: the measuring action is the same as that measured by friction current, and the measured pressure value indirectly reflects the dynamic friction resistance of the friction coupler. Although the error of the measurement mode is small, the mechanical structure of the electric switch machine needs to be modified in field work, the modified mechanical structure needs to be restored manually after measurement, but whether the technical standard before measurement can be achieved after restoration cannot be verified, and potential safety hazards exist in subsequent use.
The two measurement modes are skylight stage measurement, friction plates in the friction coupler are damaged artificially, the service life of the friction plates is shortened, the safety of switching turnout operation of the electric point switch measured by reuse at each time can be ensured before the next measurement, the obtained measurement value needs to be filled manually and cannot be stored automatically, the workload is large, and potential safety hazards exist. In addition, the existing measuring modes all belong to field measurement, turnout faults are artificially set, the turnout is measured in a non-close contact state, the influence of environmental parameters is not considered, qualitative indirect measurement is realized, and the accuracy is low; the method belongs to stage measurement, the two times of measurement are separated by a long time, the state of a turnout friction coupling cannot be reflected in real time, and the method has speculation; for measurement work requiring more emergencies, due to short time and heavy tasks, multiple persons are generally required to cooperate, measurement persons participate manually, measurement results have errors of measurement equipment and personal errors, and the reliability is low.
In view of this, the present invention is especially provided.
