Description

The device relates to the means of mechanization of loading and unloading operations, in particular to devices for mechanized opening of hatches of gondola cars.

A device for opening the hatches of railway gondola cars is known, comprising a housing, opening mechanisms comprising pushers interacting with the shut-off sectors, located in the guide slots of the housing, and openers (grippers) of flashes (AS USSR No. 846351, mc. 61 D7 / 30, 1981).

The disadvantage of the device is its unreliability, since the cantilever fastening of the grips contributes to the distortion and wedging of the levers in curved guides.

It is also known a device for opening and closing the hatches of gondola cars, which is closer in design to the proposed one, containing a movable base, power cylinders, a frame that carries

levers and carriages with push and turn bars (as. USSR. № 948724, m.К. В 61 А 7/30, 1982).

However, this device is unreliable in operation, because The movable base must move in the zone covered by the material to be discharged, the cantilever-loaded pressure pins cause the rollers to tilt in the guides, which in dustiness conditions will lead to their jamming.

The purpose of the invention is to increase the efficiency of the device by eliminating the listed drawbacks, thus simplifying the kinematics of the device and increasing its reliability.

This is achieved by the fact that the device contains a carriage mounted for movement along the guides along the gondola with a frame suspended to it, on which at least three power cylinders are mounted at an angle to each other

core for interaction with the locking device, with one of the cylinders interacting with the upper part of the sector, the second - with the lower part, and the third - with the bottom surface of the refusal.

FIG. 1 shows the device, a general view; in fig. 2 is a sectional view in FIG. one; in fig. 3 - frame with power cylinders; in fig. four

- section BB in FIG. 3; in figures 5, 6, 7 and 8

node I in FIG. 1 with the image of the sequence of operation of the power cylinders.

The device contains a self-propelled trolley 1 mounted on rails 2 with the possibility of movement along a gondola 3, to which a frame 5 with fixed power cylinders 6, 7 and 8 is suspended on the ropes 4. A platform 9 with a source mounted on it is also rigidly suspended power supply of the hydraulic system and a control panel for the mechanisms of the device 10. The power cylinders are connected to the power source by flexible hydraulic lines 11.

Gondola 3 contains: sectors 12, zakidki 13, brackets 14 and the brackets of the hatches 15.

The power cylinders 6, 7 and 8 are fixed on the frame 5 at an angle to each other so that the rods of the cylinders 6 are directed to interact with the lower part of the sector 12, the cylinders 7 with their upper part, and the cylinders 8 with the lower surface of the zakidka 13.

The cylinders 7 and 8 are fixed on the frame 5 rigidly, and the cylinders 6 are movable, rotatably, and are held in their initial position by the springs 16.

Frame 5 also contains fenders 17.

The device works as follows.

To the floor 3 installed for unloading, the cart 1 is brought in such a way that the frame 5 is opposite the hatch and mounted on the brackets 14. Then the power supply 10 is turned on and the power cylinders are actuated. The sequence of their action is shown in FIG. 5.6, 7 and 8. In FIG. 5 rods of the power cylinders are in the initial position. FIG. 6 The cylinder rod 6 rotated the sector 12, while the upper part of the sector was under the cylinder 7. When the sector rotates, the cylinder b slightly deviates from the initial position, compressing the spring 16.

FIG. 7 The cylinder 7 rod finally turned the sector 12 and released the refund 13.

FIG. The 8 cylinder rods 6 and 7 are returned to their original position, and the cylinder 8 rod removed the reflash 13 from engagement with the hatch cover bracket 15.

The hatch cover is opened under the weight of the material being unloaded, and the brackets 15, interacting with the fenders 17, remove the frame 5 from the brackets 14. Then the process is repeated on the next hatch of the gondola car.
