Abstract

The utility model relates to the field of bridge building, namely to building floating railway bridges. Known inventory property - floating railway bridge NZhM-56. In special conditions, suction anchors weighing 15 and 8 tons are used for transverse fastening of the floating bridge. The suction anchor is a concrete block with a loop for slinging, a loop for attaching a longitudinal fastening cable and a curved rail concreted into a concrete block. When tension is applied to the longitudinal fastening cable connected to the loop, the curved rail brakes over the ground and the nose of the suction anchor rests against the ground, thus creating the effect of suction to the ground. As a rule, suction anchors are transported by rail. When developing lashing schemes, due to the part of the curved rail sticking out from below, it is required to tie a suction anchor made of wood or other non-inventory structures, the manufacture of which requires effort and money. The technical result is the possibility of transporting suction anchors on railway transport without making additional strapping for their attachment to the rolling stock. To achieve a technical result, a vertical hole is made in the concrete block of the suction anchor to fit the size of the rail. In the upper part of the suction anchor block, two fastening loops are made on both sides of the vertical hole. The rail is not bent, and two holes are made in it for transportation and for work. A pin is added to the structure to fix the rail in the required position. To fix the rail during transportation, it rises until the transportation hole and two fastening loops coincide, and is fixed with a finger. Thus, during transportation, the suction anchor is placed on the rolling stock by the bottom surface of the concrete block without additional strapping. When working, before installation in the design position, the rail is lowered until the two mounting loops coincide with the hole for working in the rail, fixed with a pin. In this position of the rail, the suction anchor performs the function of longitudinal fastening. When manufacturing a suction anchor of a continued design, it is recommended to make a vertical hole for the rail with embedded metal plates to increase the service life.

Description

The utility model relates to the field of bridge building, namely to building floating railway bridges.

Known inventory property floating railway bridge NZhM-56. In special conditions, suction anchors weighing 15 and 8 tons are used for transverse fastening of the floating bridge (1. Operation manual "Floating railway bridge NZhM-56").

The suction anchor is a concrete block (Fig. 1, item 1) with a loop for slinging (Fig. 1, item 2), a loop for attaching a longitudinal fastening cable (Fig. 1, item 3) and a curved rail (Fig. 1, item 3) . 1, pos. 4), concreted into a concrete block (Fig. 1, pos. 4). When tension is applied to the longitudinal fastening cable associated with the loop (Fig. 1, pos. 3), the curved rail brakes over the ground and the nose of the suction anchor rests on the ground and thus creates the effect of suction to the ground.

As a rule, suction anchors are transported by rail. When developing linkage schemes, due to the part of the curved rail sticking out from below (Fig. 1, item 4), it is necessary to tie a suction anchor made of wood or other non-inventory structures, the manufacture of which requires effort and money. In conditions of limited time and lack of funds, the rail is often cut off, which negatively affects the functioning of the floating bridge as a whole.

The technical result is the possibility of transporting suction anchors on railway transport without making additional strapping for their attachment to the rolling stock.

To achieve a technical result, the rail must be given mobility in the concrete block and ensure its fastening when performing the functions of the longitudinal fastening of the bridge. To do this, in the concrete block of the suction anchor (Fig. 1, pos. 1) a vertical hole was made to fit the rail, in the upper part of the suction anchor block, on both sides of the vertical hole, two fixing loops were made (Fig. 2, pos. 5) , in a non-curved rail (Fig. 2, item 6) there are two holes for transportation (Fig. 2, item 7) and for operation (Fig. 2, item 8), the design contains a pin for fixing the rail in the transport position.

The essence of the utility model is illustrated by drawings, which show:

In FIG. 1 shows the suction anchor before the changes:

pos. 1 - concrete block of suction anchor;

pos. 2 - loop for slinging the suction anchor;

pos. 3 - loop for attaching a cable of longitudinal fastening;

pos. 4 - curved rail.

In FIG. 2 shows the suction anchor after the changes:

pos. 5 - two mounting loops;

pos. 6 - rail;

pos. 7 - opening for transportation;

pos. 8 - hole for work.

The utility model is implemented as follows.

To give the rail (Fig. 2, item 6) mobility in the concrete block of the suction anchor (Fig. 1, item 1), a vertical hole is made to fit the size of the rail. In the upper part of the suction anchor block, on both sides of the vertical hole, two fastening loops are made (Fig. 2, item 5), and two holes are made in the rail for transportation (Fig. 2, item 7) and for work (Fig. 2, item 8). To fix the rail (Fig. 2, pos. 6) during transportation, it rises until the transportation hole (Fig. 2, pos. 7) and two fastening loops (Fig. 2, pos. 5) coincide, and is fixed with a finger. Thus, during transportation, the suction anchor is placed by the lower surface of the concrete block (Fig. 1, item 1) on the rolling stock without additional strapping.

During operation, before installation in the design position, the rail (Fig. 2, pos. 6) is lowered until the two mounting loops (Fig. 2, pos. 5) coincide with the opening for work (Fig. 2, pos. 8) in the rail (Fig. 2, item 6), is fixed with a finger. In this position of the rail (Fig. 2, item 6), the suction anchor performs the function of longitudinal fastening.

In the manufacture of a suction anchor of a continued design, in order to increase the service life, it is recommended to make a vertical hole under the rail with embedded metal plates.

Thus, with the changes described above, when transporting the suction anchor, no additional strapping is required, which saves effort and money.
