RU203466U1 - FITTING STOP - Google Patents

Abstract

The utility model relates to the design of fitting stops used to fix a freight container on a transport platform. The fitting stop is made in the form of a thrust pin (1), fixed on the base (2) with the supporting surface "A". The thrust pin (1) contains a head (1.1) with an inclined front guide surface (1.2). The leg (1.3) of the thrust pin (1) is made with a rear inclined guide surface (1.4). The height "H" of the top of the head (1.1), measured from the upper support surface "A" of the base (2), is made in the range from 80 mm to 120 mm. On the rear guide of the inclined surface (1.4) of the leg (1.3), there is a lower stop step (1.5) with a height "h" from 4 mm to 20 mm. The claimed implementation of the height "H" allows you to obtain an increased height of the fitting stop and a large area of the inclined front surface (1.2) of the stop pin (1). This allows for better guiding properties of the fitting stop when lowering the cargo container, as well as more reliable fixation on the transport platform. The technical result is an increase in the operational reliability of the fitting stop. 2 c.p. f-ly, 4 dwg

Description

The utility model relates to the design of devices for securing freight containers on a railway transport platform. The utility model can also be used for other types of specialized transport.

Known fitting stop for fixing the cargo container on the transport platform, made in the form of a thrust pin, fixed by its leg on the base, the thrust pin contains a head with an inclined front guide surface, the leg of the thrust pin is made with a rear inclined guide surface, see RU 175528, B61D 3 / 18, B60P 7/13, publ. 12/07/2017 (prototype).

The technical problem inherent in this fitting stop is its low operational reliability due to the weak guiding ability of the inclined front surface of the thrust pin head due to its small area and the low height of the thrust pin head relative to the base support surface.

The technical result of the claimed utility model is to increase the operational reliability of the fitting stop.

The specified technical result is provided by a fitting stop for fixing the cargo container on the transport platform, made in the form of a thrust pin, fixed by its leg on the base, the thrust pin contains a head with an inclined front guide surface, the thrust pin leg is made with a rear inclined guide surface, height "H" the top of the head, measured from the upper support surface "A" of the base, is made from the range from 80 to 120 mm, on the rear guide surface of the leg, a lower stop step of height "h" is made, measured from the upper support surface "A" of the base and maintained in the range from 4 to 20 mm; the height "h" of the stop step can be made from 12 to 16 mm; the height "H" of the head from the support surface "A" can be made equal to 100 mm.

The claimed utility model differs from the prototype in that the height "H" of the top of the head, measured from the upper support surface "A" of the base, is made from the range from 80 to 120 mm, on the rear guide surface of the leg there is a lower stop step with the height "h" measured from the upper supporting surface "A" of the base and maintained in the range from 4 to 20 mm; the height "h" of the stop step is made from 12 to 16 mm; the height "H" of the head from the support surface "A" is made equal to 100 mm. Such differences from the prototype make it possible to assert that the claimed utility model corresponds to the criterion of patentability - "novelty".

The utility model is shown in the drawings, where:

- in FIG. 1 - fitting stop for fixing the cargo container on the transport platform, main view;

- in FIG. 2 - the same, front view;

- in FIG. 3, 4 - the same, isometric views.

The fitting stop for fixing the cargo container on the transport platform is made in the form of a thrust pin 1 (Fig. 1, 2), fixed on the base 2 with the supporting surface "A". The thrust pin 1 contains a head 1.1 with an inclined front guide surface 1.2. The leg 1.3 of the thrust pin 1 is made with a rear inclined guide surface 1.4. The height "H" (Fig. 3, 4), the top of the head 1.1, measured from the upper support surface "A" of the base 2, is made in the range from 80 to 120 mm. On the rear guiding inclined surface 1.4 of the leg 1.3, a lower stop step 1.5 with a height "h" is made, measured from the upper support surface "A" of the base 2 and maintained in the range from 4 to 20 mm. The height "h" of the stop step 1.5 can be made from 12 to 16 mm. The height "H" of the head 1.1 can be made equal to 100 mm.

The utility model is used as follows.

To place the freight container on the transport platform, the openings of the fittings (not shown) of the freight container are placed over the corresponding fitting stops. The cargo container is lowered down. When lowered down, the inclined front guide surface 1.2 of the head 1.1 serves as a guide surface for the holes of the cargo container fittings. With further lowering of the cargo container down, the fittings begin to interact with the rear guiding inclined surface 1.4 of the leg 1.3, directing the fittings under the front protrusion 1.6 and with support on the support surface "A" of the base 2. In this case, the lower stop step 1.5 serves as a stop against horizontal movement fittings on the support surface "A" of the base 2.

The reliability of the orientation of the cargo container and the reliability of its basing on the transport platform is directly related to the dimensions of the elements of the fitting stop. Execution of the height "H" of the head top 1.1, measured from the upper support surface "A" of the base 2, maintained from the range from 80 to 120 mm, allows to obtain an increased vertical dimension of the head 1.1 of the fitting, and, therefore, to increase the area of the inclined front surface 1.2 of the thrust pin 1. This allows to provide better guiding properties of the fitting stop when lowering the cargo container onto the transport platform, as well as to ensure its more reliable fixation during transportation on the transport platform under high dynamic loads, since on the fitting stops of increased height "H" the cargo container will be located more stable position, the likelihood of its removal and release from the fitting stops is reduced. Making the height "H" of the head top 1.1 from the upper supporting surface "A" of the base 2 less than 80 mm does not provide the declared result - an increase in the operational reliability of the fitting stop, since in this case, the low height of the head top 1.1 relative to the supporting surface "A" will not provide the developed area of the inclined front surface 1.2 of the thrust pin 1 and the reliable installation of the cargo container. Achievement of height "H" more than 120 mm is not possible due to limitations in the design of the cargo container fittings.

The thrust step 1.5 can be made with a height "h" from 4 to 20 mm, measured from the supporting surface "A" of the base 2. If the height "h" is less than 4 mm, there is a risk of losing the guiding ability of the thrust step 1.5. The implementation of the stop step 1.5 with a height "h" of more than 20 mm reduces the rear guiding surface 1.4 of the leg 1.3, which will negatively affect its guiding ability.

Thus, the proposed design of the fitting stop for fixing the cargo container on the transport platform allows increasing its operational reliability.
