Description

The utility model relates to the means of technical control in mechanical engineering, in terms of the manufacture and repair of hopper cars, is intended to control the transition of the levers of the hatch covers of the unloading mechanism through the "dead spot".

There is a known method of controlling the transition of the levers of the covers of the hatches of the unloading mechanism through the "dead spot" using the original magnetic template, which consists of two magnetic heads interconnected by a string of white rubber. When measuring the controlled value, one magnetic head is installed on the end of the trunnion of the hatch cover, and the other - on the end of the shaft connecting the lever with the turn fork. In this case, sufficient tension of the template string must be ensured. The value of the transition of the lever through the "dead center" is measured along the perpendicular lowered (restored) to the plane of the string and passing through the center of the end of the turn shaft (https://sudact.ru/law/rasporiazhenie-mintransa-rf-ot-30032001-n-an -25-r/, paragraph 2.2 Technical instructions for the repair of cars for coke, pellets and sinter).

The disadvantage of this method is the relatively low measurement accuracy, because the string must be constantly kept in a taut state, and to measure the distance from the center of the end of the turn shaft to the string, it is necessary to use a ruler, while excluding the deflection of the stretched string.

Close analogues of the device design have not been found.

The technical problem is to ensure accurate control of the transition of the levers of the hatch covers of the unloading mechanism through the "dead spot" in the manufacture and repair of hopper cars. The "dead point" is the location of the centers of the fork roller of the shaft of the unloading mechanism relative to the center line passing through the trunnion of the hatch cover and the center of the shaft of the unloading mechanism. The correct passage of the hatch cover levers through the "dead spot" ensures reliable closing of the hatch covers on the car, excluding their arbitrary opening, and, accordingly, the safety of the cargo during the transportation and operation of the cars. The main difficulty in controlling the passage of the hatch cover levers of the unloading mechanism through the “dead spot” is the design feature of the unloading mechanism, namely, that the base points that are involved in the measurement are in different planes. It is technically impossible to make an accurate measurement without a specialized device.

The technical result is to ensure accurate control of the transition of the levers of the hatch covers of the unloading mechanism through the "dead spot" in the manufacture and repair of hopper cars.

The technical result is achieved due to the fact that the developed device contains an all-metal rod, with a movable catcher with a fixing screw, a fixed catcher, a movable panel with a ruler and a probe installed on it. The ruler has a measuring scale. The position of the ruler on the panel is set by a latch.

The claimed utility model is illustrated by drawings.

In FIG. 1 shows a device for controlling the transition of the levers of the hatch covers of the unloading mechanism through the "dead spot". In FIG. 2 shows a diagram of the transition of the levers through the "dead center" (the location of the centers of the shaft of the turning fork 10 and the shaft of the unloading mechanism 11 relative to the axial line passing through the pin of the hatch cover 9 and the center of the shaft of the unloading mechanism 11). In FIG. 3 and FIG. 4 shows the installation of the proposed device when performing control of the transition of the levers of the hatch covers of the unloading mechanism through the "dead spot".

Positions on figures:

1 - all-metal rod;

2 - movable catcher;

3 - fixing screw;

4 - fixed catcher;

5 - mobile panel;

6 - ruler with a measuring scale;

7 - probe;

8 - probe lock;

9 - trunnion of the hatch cover;

10 - turn fork roller;

11 - the center of the shaft of the unloading mechanism.

The device for controlling the transition of the levers of the hatch covers of the hopper car unloading mechanism through the “dead spot” includes an all-metal bar 1, on which a movable catcher 2 with a fixing screw 3, a fixed catcher 4, a movable panel 5, including a ruler 6 with a probe, are installed 7. A measuring scale is applied on ruler 6. The position of the ruler in panel 5 is set by latch 8.

The fixed catcher 4 is aligned with the center of the shaft of the unloading mechanism 11, and the movable catcher 2 is aligned with the trunnion 9 of the hatch cover. The function of the mobility of the catcher 2 is necessary for compensation when the base measuring points are located relative to each other. After aligning the movable catcher 2 with the pin 9 of the manhole cover, the position of the catcher is securely fixed with a screw 3. The pointed end of the probe 7 is aligned with the center of the shaft of the rotation fork 10. The position of the probe 7 is possible by moving the movable panel 5 along the rod 1 in the horizontal direction, and by moving ruler 6 relative to panel 5 in the vertical direction. After aligning the pointed end of the probe 7 with the center of the turning fork shaft 10, the position of the ruler 6 is securely fixed with the latch 8. Next, the readings are taken from the measuring scale of the ruler 6. The result obtained on the scale will correspond to the exact value of the transition of the levers of the hatch covers of the unloading mechanism through the “dead spot”.

Usage example.

In the manufacture of hopper cars, a device was used to control the transition of the hatch cover levers of the hopper car unloading mechanism through the "dead spot". The indication on ruler 6 during the measurement process is from 8 to 25 mm, which corresponds to the permissible standard value for the transition of the levers of the hatch covers of the unloading mechanism through the "dead spot" in the manufacture of hopper cars. In accordance with this, reliable closing of hatch covers on the wagon is ensured, excluding their arbitrary opening, and, accordingly, the safety of cargo during transportation and operation of wagons.

Thanks to the use of the device, high measurement accuracy is ensured when controlling the passage of the levers of the hatch covers of the unloading mechanism through the "dead spot" and cases of production of hopper cars with defective unloading mechanisms were excluded, the accuracy and quality of workmanship made it possible to increase the output of hopper cars, eliminate claims from consumers.
