Description

 The invention relates to the technology of mechanization of loading and unloading operations in railway transport, in particular to the mechanization of opening and closing manhole covers of railway gondola cars.

 There is a method of closing the hatchways of open wagons with the help of a special device, which is a pneumatic cylinder, which is attached to the gripping levers (V.I. Gridyushko, V.P. Bugaev, N.Z. Krivoruchko "Wagon economy" .- M .: Transport 1988, pp. 227-228). A wagon with open manhole covers is installed so that the gripping levers are along the axis of the manhole covers. After supplying compressed air to the lower part of the cylinders, the pistons rise and move the levers upwards, which grab the manhole covers and raise them to contact the contact plane, while the lock bolts engage with the locking angles of the manhole covers.

 The disadvantages of the device used to implement this method are the great physical effort of a person, the considerable time required to close the hatch covers of gondola cars, and the fact that this device cannot be used to open the hatch covers.

 A device is known for controlling hatches of railway gondola cars during their hydraulic cleaning (description of the invention to auth. St. USSR N 1622205, IPC B 61 D 7/26, 01/23/1991), including a rod, hook and a flexible element, at the end of which a grip is made.

 The disadvantages of this device are the significant investment of time in opening and closing manhole covers using this device.

 The problem solved by this invention is to reduce the physical effort of a person, that is, the mechanization of the process of opening and closing the hatch covers of open wagons, as well as a significant reduction in the time not opening and closing.

 The tasks set for this technical solution are achieved in that the opening and closing of the manhole covers is carried out using a special device made in the form of a rod, one end of which is equipped with a metal tip, at the end of which there is a rectangular hook through a hinge, at a certain distance from the hinge, a flexible element is fixed on the tip, at the end of which a semicircular shape is gripped.

 Indeed, the present invention solves the problem of mechanizing the process of opening and closing manhole covers of railway cars, while the labor of workers engaged in this operation is greatly facilitated, the time for opening and closing is significantly reduced, and it is possible to control the hatches, i.e. open them by a certain amount with a given slot gap.

 Comparative analysis with the prototype shows that the inventive device is characterized in that it has a hook and a grip, with the help of which the opening and closing of manhole covers takes place.

 Thus, the claimed device meets the criteria of the invention of "novelty."

 Comparison of the proposed solution not only with the prototype, but also with other technical solutions in the art did not allow them to identify signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "significant differences".

 The invention is illustrated by drawings, where in FIG. 1 shows the proposed device in position with the sunroof closed; in FIG. 2 shows the proposed device in position with the hatch open; in FIG. 3 - general view of the device; in FIG. 4 is a view A in FIG. 3.

 A device for controlling hatches of railway cars 1 contains a wooden rod 2, at one end of which there is a metal tip 3, a hinge 4 with a rectangular hook 5 is installed at the end of the metal tip 3, a flexible element is fixed at a certain distance from the hinge 4 to the opposite end of the rod 2 6, at the end of which a grip 7 having a semicircular shape is mounted.

 Device 1 operates as follows.

 Before hydraulic cleaning of railway gondola cars 8, the latter are at the point of preparation for gondola cars. It is here that one of the two pressure heads of the hatch is opened with a sledgehammer, consisting of a cap 9, sector and level 10. Between the level 10 and the side wall of the gondola car 9, one worker installs a grip 7 of device 1, and a rectangular hook 5 of the same device is put on for a tide manhole cover 11 and hold the device 1 in this position. At this time, the second worker knocks the sledgehammer 9 of the second lock of the hatch cover 11 out of engagement with the corner and the hatch cover 11 completely lays on hook 5 and gradually lowers to the desired distance, which sets the worker holding this device.

 To fix the hatch in the desired position, use a special device, a metal bracket with a hook in the lower part. A metal bracket with its upper part is thrown onto the protruding part of the constipation, and the lower part with a hook is under the gondola hatch, the manhole cover rests on this hook using the proposed device 1. Then, the device 1 is removed.

 With such fixed openings for gondola cars manhole covers, the latter are fed to the platform where they are hydraulically cleaned. Gondola cars pass with a low speed through a hydraulic unit with pressure jets. When hydraulically cleaning railway gondola cars, manhole covers should not open fully to avoid oversized vehicles leaving gondola cars, which prevents further hydrotransport. The height of the metal bracket depends on the distance by which you need to open the manhole covers.

 After cleaning, gondola cars leave the site where the cleaning took place, here, thanks to the proposed device 1, the manhole covers are closed. To do this, again the grip 7 is installed between the bar 10 and the wall of the gondola car 8, and the hook is put on for the tide of the manhole cover. For the wooden rod 2, the worker lifts the hatch, while the coffins 9 of both constipations mesh with the corners. Manhole covers are closed.

 The use of this device can significantly reduce the physical efforts of workers when opening and closing the hatch covers of gondola cars, significantly reduce the time spent on these operations, and also allows you to open the hatch covers at any given distance with a certain gap gap required for hydraulic cleaning of railway gondola cars.
