Description

The group of inventions relates to car building, namely, to the locking device of the hatch of a gondola car.

A device for locking the hatch, containing a cap with a hole and a tooth, a sector interacting with it, and a horizontally fixed bar (hereinafter referred to as a “bracket”) on the lower trim of the side wall of the gondola body, wherein the sector is made with an open profiled cut-out, where the working protrusion, formed by this cut, is elastically movable within the gap between its apex and the main part of the sector, and the sector is located on the rear tail side of the tooth of the haul (see AC 295700, bull. No. 8. 1971), analog.

The main disadvantages:

- imperfection of the design;

- unreliable jamming;

- inconvenience in operation;

- low competitiveness.

A locking device for a gondola car’s hatch is known, which contains a cot and a sector pivotally mounted in a horizontal bracket mounted on the lower harness of the gondola car body and an arm (hereinafter referred to as the “corner”) interacting with the cog tooth, where the sector working contour is formed by two smoothly conjugated surfaces of different curvatures, moreover, the lower part of the contour has a large radius, and the upper one is smaller (see AC 1219438, bull. No. 11. 1986) - a prototype.

The main disadvantages of the locking device are the same as in the analogue, i.e. in the previous one.

From these shortcomings, the free locking device of the hatch of the gondola car, the task of which is:

- design perfection;

- exclusion of arbitrary sector rotation;

- increase the term of operation;

- competitiveness.

Deficiencies arose mainly due to imperfections in the design, i.e. the interaction of the flap, sector and corner, where the flip and sector are pivotally mounted on the lower trim of the side wall of the body, and the sector is pivotally mounted on the lower trim of the side wall of the body, and the sector, without a locking element, wedges, but does not lock the back of the cast when exposed to the sector, the pivot and the corner under dynamic and vibrational loads, pushing out occurs, and then the sector turns, the sector spontaneously weakens, the pivot disengages from the corner and the manhole cover opens. To prevent spontaneous opening of the manhole cover, it is necessary to additionally wedge the gap between the cap and the sector with wooden wedges and additionally tie a cap and a corner with wire, where for this purpose a hollow for holding the wire is provided on the elongated horizontal shelf of the corner (indicated by bold lines in figure 1 and figure 2 )

The proposed inventions are free from these drawbacks, in which the task of simplifying the design, reliability and preventing spontaneous movement of the sector and casting, ease of manufacture, maintenance and reliable locking of the manhole cover is solved.

To achieve the technical results, the locking device for the gondola hatch contains a lock, a sector, a corner and a bracket that is fixed rigidly to the lower trim of the side wall of the body, where a sector equipped with a half-lock with a working surface is pivotally fixed, the corner is also equipped with a half-lock and a working surface, _ and when they interact with their working surfaces, a lock joint is formed, which ensures locking more reliably, while the cloak itself is pivotally fixed in the vertical bracket of the lower harness ke side wall of a gondola car body.

The signs distinguishing the proposed locking device of the hatch from the closest known to him according to A.C. 219438 are as follows:

- The sector is fixed movably in the middle part of the zakidka and is equipped with a half-lock, the working side of which is made in the form of a closed corner, while the sector interacts with the half-lock of the corner, and upon contact with their working surfaces form a locking joint, which is the link “lower strapping - vertical bracket - “Sock - sector - corner”, while the mobility of the sector is ensured by the presence of an opening in the tail section of the sectotea and an additional hole in the sack.

- The cap is provided with an additional second hole for securing the sector, where its outer contour in the area of this hole is reinforced in the form of a bulge.

- The bracket is flat with two vertical holes for attaching the boot on the lower trim of the side wall of the gondola car body.

- The side wall of the gondola car body is equipped with two vertical holes in the zone of attachment of the dress on one axial.

Distinctive features that distinguish the proposed locking device of the hatch, is new and meets the criterion of "Novelty." These signs led to a simplification of the design, assembly and reliability in operation, as there is no wedge locking and tying with a wire between the tie and the sector, which allowed us to create the link “Bottom harness - vertical bracket - roll-corner”.

When studying other known solutions in this area, the features that distinguish the claimed solution were not identified, which ensures the inventions meet the criterion of "Inventive step".

The claimed solutions are so interconnected that they form a single inventive concept. Indeed, the locking device of the gondola hatch can be made and it can only work on the proposed locking device, therefore, the requirement is “unity of invention”.

The proposed device is illustrated by drawings, in which Fig. 1 shows the locking device of the hatch of the gondola car assembly in the working locked state, where the half-locks of the sector and corner are in the closing stage, where the technological gap "H" between the flush and the corner (general view with a break fasteners and the end of the corner). Figure 2 is the same where the locking device of the gondola car door hatch assembly is shown in the working, but not locked state with the necessary technological gap "H ₁ " between the sector half-lock and the corner half-lock, i.e. not at the stage of closing together.

The locking device of the hatch of the gondola car contains a bracket 1 (Fig. 1), fixed rigidly to the lower trim of the side wall 2 of the body, a two-toed cloak 3 interacting with the corner 4, the hatch cover 5, the cloak 3 provided with a sector 6, interconnected movably through an additional the hole 7 in the tie 3 with a bolted connection 8, and the additional hole 7 of the snap is located above the large tooth 9, while the sector 6 has a straight flat body 10 and consists of a tail portion 11 with a hole 12 and a free end 13, where it is located between them a half-lock 14 with a closed common angle "α" facing the tail portion 11, a corner 4 protruding outside the hatch cover 5 is provided with a half-lock 15 and can be located anywhere on the upper horizontal shelf 16 of the corner 4 and forms a closed angle "α ₁ "(Figure 2), equal to the closed angle" α "(figure 1) which ensures reliable closure with the half-lock 14 of sector 6 in the closed and locked state of the hatch 5.

The assembly of the device is as follows. The bracket 1 is rigidly fixed to the wall of the body 2 with fasteners 19, the assembly of the hook and sector is assembled, where sector 6 with its hole 12 is put on the bolt connection 8 inserted through the hole (not shown) in the middle part of the stick 3, and is fixed movably by bolt connection 8, after which the tuck 3 with its tail part 20 by the hole 7 is inserted into the space between the bracket 1 and the lower trim by the side wall 2 and is fixed by the fasteners 21 movably.

Opening the hatch is as follows (figure 1). By striking the flip towards the closing side (shown by the arrow of striking), the clearance “N” between the flip 3 and the half-lock 15 of corner 4 is eliminated. the sector 6 is fixed on the cap 3 by a bolt connection, the gap "H" moves and a gap "H ₁ " (Fig. 2) is formed between the half-lock of the corner 15 and the half-lock of the sector 14 (Fig. 2), thus closing is closed, the lock connection between a half-lock 15 of corner 4 and a half-lock of sector 14 (Fig. 2), from here the system disengages. The closed angle "α ₁ " and the gap "H ₁ " are taken as maximum and minimum (respectively). To remove the half-lock 14 of sector 6 from the area of the castle connection, it is necessary to turn the sector 6 around the bolted connection counterclockwise. Then, by hitting 3 (shown conventionally by the arrow of striking), tooth 9 of hinge 3 is disengaged from the lower shelf 17 of corner 4 and the hatch 5 opens.

Locking the hatch is as follows. The hatch cover 5 (Fig. 2) is pressed to the lower trim of the side wall 2, the cotter 3 is made by a large tooth 9 under the lower horizontal shelf 17 of the corner 4 and by hitting the cotter 3 (shown by an arrow) towards the corner 4, the tooth 9 is completely pressed by the tooth 9 of the manhole cover 5 to the lower trim of the wall 2 of the gondola car body, then the bolt 6, which is in a free state (shown by conditional lines), is rotated clockwise to the bolt connection 8 until it descends into the zone 18 of the half-lock 15 of the corner 4 and hit by the bolt 3 (shown by the arrow marked by the conditional paragraph irom) - in the direction of opening in order to eliminate the gap "H ₁ ", ie the closure of the half-locks 14 and 15 of sector 6 and corner 4 - this is what a positive effect is achieved, i.e. locking.

Considering that the operation of a gondola car is based on the principle of the force closure of the moving links under dynamic loads and vibration, no matter how hard the clasp is pressed against the corner, it will relatively quickly begin to move towards the exit from the mesh with the corner, which implies that there is no need to lock devices by striking the buckle in the direction of opening to completely lock the lock connection, the locking process will occur in the automatic running mode of the gondola car and is an additional guarantee reliably a locking cap gondola hatch.

The proposed device, in comparison with the known one, provides a reduction in the nomenclature of parts by replacing the left and right brackets and sectors of one name each, in the sectors the depression is removed where the spring is placed to jam the sector from turning it (see AC 1219438, bull. No. 11. 1986 ) The dispersion zone of the holes in the places of installation of the zakidka on the lower belt of the body wall is reduced and their location on the same vertical axis instead of four holes in two, thereby increasing the reliability of the design of the lower belt of the body wall, reducing labor intensity, improving the working condition by improving the usability of the mechanism, because there is no need to jam with the wooden wedges the contact zone of the zakidka and the sector and additional insurance from tying the zakidki and the corner with wire, where for this purpose a recess 22 is provided on the extended corner (shown in bold in Fig. 1 and Fig. 2) to prevent the wire from shifting, reducing metal intensity of the mechanism due to changes in the design of the bar and the sector can significantly increase the operational reliability of the device and gondola by changing the principle of locking zakidki and corner in work than the locked position.

The proposed inventions were tested on prototypes in laboratory conditions, which proved their industrial applicability. Tests on mock-ups showed good qualities of fixing and locking the device, simplicity of design, which facilitates assembly and maintenance of a gondola car, is economically profitable and, most importantly, can be quickly put into production with minimal costs, increase competitiveness, and the existing rolling stock of such gondola cars operating in the country's railways, can be upgraded as soon as possible and thereby bring significant economic benefits, and most importantly, increase gondola-competitive on a global level.
