Description

The inventive utility model relates to couplers for railway vehicles and can be used for technological rolling cars, not equipped with automatic coupling SA-3, shunting locomotive.

A device for coupling wagons is known (RF patent No. 86158 U1, B61G 7/00, publ. 08/27/2009), comprising a housing with a round through hole, a telescoping telescopic rod in the housing with a through hole, a spring-loaded pin with the possibility of its location in the indicated holes of the housing and the rod when they are combined.

This device has a complex construction of the drive mechanism, and considerable time is required for installation and dismantling of such a device on a carriage.

The closest technical solution (adopted as a prototype) is an intercar connection (RF patent No. 2026222, B61G 7/00, publ. 01/09/1995), containing a rod with a round through hole, a telescopically mounted retractable rod with a through hole, the rod position lock with the possibility of its location in the indicated holes of the rod and the rod when they are combined, the locking axis and rigidly fixed to the housing rod to accommodate the specified lock.

This connection is designed to hold cars at a certain distance during repair work. During a cyclical repeatedly repeating technological operation of moving cars, its use is impractical. Since during dismantling and for bringing the latch into working position, it is necessary to perform a number of additional operations, including 180 ° flipping (for the latch to enter the upper case), which, taking into account the time spent on work and the increased risk of their execution, is unacceptable.

Since the through holes in the rod and the rod are round, to fix the rod in the extended position, it is necessary to ensure the exact position of the rod relative to the rod - the coaxial arrangement of the round holes, which also complicates the installation process.

The objective of the proposal is to simplify the installation and dismantling of the adapter for the technological rolling of cars.

For this, the adapter for technological rolling of cars contains a rod with a round through hole, a telescopically mounted retractable rod with a through hole, a rod position lock with the possibility of its location in these holes of the rod and rod when they are combined, a locking axis and rigidly fixed to the housing rod for placing the specified latch. What is new is that the hole in the rod is made in the form of a groove, the rod position lock is made in the form of spring-loaded fingers installed in the respective housings, the longitudinal axis of the rod and these fingers lie in the same horizontal plane, and the locking axis passing through the groove of the rod is fixed to the outer diameter of the rod and is configured to alternately interact with the ends of said groove.

In addition, the fingers are equipped with handles, and grooves are made in the housings for fixing the finger grips.

The technical result was expressed in the following.

The hole in the rod in the form of a groove makes it possible to fix the rod at a certain distance interval, determined by the length of the groove. There is a power reserve for matching the holes of the rod and rod and the operation of the fingers. This provides the convenience of coupling and simplifies the installation of the adapter for technological rolling cars.

Fixing the locking axis on the outer diameter of the rod and performing it passing through the groove with the possibility of variable interaction with the ends of this groove limits the stroke of the rod relative to the rod and fixes it in extreme positions (extended and retracted). The rod moves inside the rod until the axis stops in the end of the groove, and when it coincides with the hole of the rod, the fingers trigger. This simplifies the installation of the adapter for technological rolling of cars and provides reliable fixation of the length of the structure in the working position.

The execution of the rod position lock in the form of spring-loaded fingers installed in the respective housings creates a latching force when the fingers operate and they fall into the groove, which simplifies installation.

When the longitudinal axles of the bar and fingers are located in the same horizontal plane, both fingers are in the visibility range of the coupler, which provides the convenience of pulling and moving the fingers to the inoperative position, simplifying the dismantling of the adapter for the technological rolling of cars.

The presence of spring-loaded fingers on the handles and the execution of grooves in the housings for fixing these handles facilitates the process of transferring the fingers from the working position to the idle position and holding them in it.

The accompanying drawings depict:

FIG. 2 is a view A in FIG. 1 (spring-loaded fingers in working position);

FIG. 3 is a view A in FIG. 1 (spring-loaded fingers in the idle position);

FIG. 4 is a remote view B of FIG. 3.

The adapter for technological rolling of cars contains a rod 1, a telescopically mounted retractable rod 2, a locking axis 3 (Fig. 2, 3), a rod position lock made in the form of spring fingers 4, 5 mounted in the corresponding cases 6 rigidly fixed to the rod , 7. At the “free” ends of the rod and the rod, eyes 8, 9 are made perpendicular to each other for connecting the adapter by means of pins 10 to the element 11 of the cover platform 12 and the technological bracket 13 mounted on the frame 14 of the body rut. The rod 1 has a round through hole 15, and the sliding rod 2 has a through hole 16 in the form of a groove. The spring fingers are arranged to be located in the holes 15 and 16 when they are combined.

The locking axis passing through the groove 16 of the rod, is mounted on the outer diameter of the rod and is made with the possibility of variable interaction with the ends of the groove. The rod relative to the rod has a stroke equal to the length of the groove and is fixed in the extreme working position on one side of the groove with fingers 4, 5, and on the other with the locking axis 3. The longitudinal axis of the rod and fingers lie in one horizontal plane. To transfer from a non-working position to a working one and vice versa, the fingers are equipped with handles 17. Grooves 18 are made in the cases (Fig. 4) for fixing the handles in the non-working position.

The adapter for technological rolling of cars is a rigid coupling that allows you to transfer forces during rolling and to keep the car body at a certain distance from the cover platform. At the initial stage of the car assembly cycle, the adapter is installed manually without additional installation manipulations, ensuring the car is moved to perform a given cycle of technological operations. At the stage of replacement with a standard coupling device, the adapter is dismantled, and the cycle of its use is repeated.

The adapter for technological rolling cars works as follows.

Initially, preliminary work is carried out, including the installation of a technological bracket 13 on the car body frame 14 of the movable carriage, as well as mounting the adapter by connecting the rod eye 9 to the bracket 13 using pin 10. A support device 19 is used to hold the adapter in horizontal position (for example, coupling belt). The operation of the coupling with the platform cover 12 directly includes the following actions. The cover platform is brought to the car body at a distance that allows the element 11 and the eyelets 8 of the retractable rod 2 to be connected with a pin 10 with the possibility of moving the rod in the rod along the groove 16. The rod moves manually, while fingers 4,5 are initially removed in the bodies 6, 7 and are out of service. After installing the pin, the coupler by turning the fingers with the handles 17 90 ° translates them into the working - spring position, the shunting locomotive applies traction, and the rod 2 is set to the transport position, and at the same time it is automatically blocked from the reciprocating movements, provided by the stop lock axis 3 at the end of the groove of the rod and the operation of the spring-loaded fingers. The car body and the cover platform are disengaged in the reverse order. After stopping and installing brake shoes (not shown) under the wheels of the bogies of the car body, the fingers 4, 5 are set to the idle position to release the rod 2 by removing the pin 10 from the joint of the eye 8 with the element 11 of the cover platform. This operation of the coupler-release is performed repeatedly throughout the entire assembly (repair) cycle of the car.
