RU192285U1 - PONTON SECTION FOR ENSURING A SCREENLESS INSTALLATION - Google Patents

Abstract

The utility model relates to the field of bridge building, namely to the construction of temporary bridges. A section of the pontoon from NZhM-56 property is known, which is a box and consists of a frame and sheathing made of sheet steel. When installing the support superstructure from the IMI-60 kit, it was planned to install electric hoists to the foundation. To install electric hoists on the foundation, lifting equipment and sufficiently large labor costs are necessary. Due to an accidental shift of the superstructure during its installation, there is a possibility of damage to the electric hoists. Thus, to create traction, it is necessary to search for alternative devices. The technical result can be the equipment of the pontoon section from the NZhM-56 property to exclude the installation of traction devices on the foundation. To achieve a technical result, the power plant and electric hoists necessary to create traction can be placed on the deck of the NJM-56 pontoon section, and two curved plates with guide rollers are hinged to the pontoon bulwarks. A useful model is implemented as follows. Curved plates are pivotally attached to the bulwark of the pontoon section from the NZhM-56 kit at the required distance. A guide roller is attached to each of the plates so that its top is above the foundation. Electric hoists and a power station are installed on the deck in the required places opposite the guide rollers. The pontoon section with the above equipment is transported to the foundation of the temporary bridge support and attached to the foundation. After the design approach for the craneless installation, the ends of the electric winch cable are attached to the superstructure and it is installed. Before by tension to prevent the pontoon section from tipping over into its compartments, it is necessary to fill in water (ballast) in the volume, according to previously performed calculations. Ohm, the claimed technical result, which consists in eliminating the need to install electric winches on the foundation, has been achieved.

Description

The utility model relates to the field of bridge construction, namely to the construction of temporary bridges.

A known support superstructure from the IMI-60 kit (inventory bridge-building property) comprising racks of abutting elements with flange sheets at the ends located on the racks of the head beams of the upper section of the superstructure, characterized in that the head beams and beam beams are made with the possibility of a connector in the middle part with by welding flanges, and the flanges separating the head beams are made with the installation of hinge loops in the upper part, due to which it can be possible to disconnect and connect the flanges ba lock in the middle part (1. utility model patent No. 180193 priority of 02/01/2018).

Known section of the pontoon (Fig. 1 pos. 1) from the property NZhM-56, (2. Technical description and instructions for installation, transportation, storage and operation of the floating railway bridge NZhM-56) which is a box and consists of a frame and sheathing of sheet steel.

When installing the add-on supports from the IMI-60 kit, it was planned to install electric winchs (Fig. 1, pos. 2) on the foundation (Fig. 1, pos. 3). To install electric winches (Fig. 1, pos. 2) on the foundation (Fig. 1, pos. 3), lifting equipment and sufficiently large labor costs are necessary. Due to the accidental shift of the superstructure during its installation, there is a possibility of damage to the electric hoists (Fig. 1, item 2). Thus, to create traction, it is necessary to search for alternative devices.

The technical result can be the equipment of the pontoon section (Fig. 1 pos. 1) from the NZhM-56 property in such a way as to exclude the installation of traction devices on the foundation (Fig. 1 pos. 3).

To achieve a technical result, the power plant (Fig. 1, pos. 4) and electric winch (Fig. 1, pos. 2) necessary to create traction can be placed on the deck of the NZhM-56 pontoon section (Fig. 1, pos. 1), and to the pontoon bulwarks (Fig. 1, pos. 5) pivotally attach two curved plates (Fig. 1, pos. 6) with guide rollers (Fig. 1, pos. 7).

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

The figure 1 shows the equipment of the pontoon for the implementation of the craneless installation of the add-on:

pos. 1 - pontoon section from NZhM-56 property;

pos. 2 - electric winches;

pos. 3 - pile foundation support temporary bridge;

pos. 4 - power station;

pos. 5 - bulwark of the pontoon section;

pos. 6 - curved plates;

pos. 7 - guide rollers.

A utility model is implemented as follows. To the bulwark (Fig. 1 pos. 5) of the pontoon section (Fig. 1 pos. 1) from the NZhM-56 kit, curved plates (Fig. 1 pos. 6) are pivotally attached at the required distance as shown in the figure (Fig. 1). Each of the plates is attached along the guide roller (Fig. 1, item 7) so that its top is higher than the foundation (Fig. 1 item 3). To the deck, in the required places opposite the guide rollers, electric winches (Fig. 1 pos. 2) and a power plant (Fig. 1 pos. 4) are installed.

The pontoon section (Fig. 1, pos. 1) with the above equipment is transported to the foundation of the temporary bridge support (Fig. 1, pos. 3) and attached to the foundation.

After the design approach for the craneless installation, the ends of the electric winch cable are attached to the superstructure (Fig. 1, item 2) and it is installed as described in the source [1].

Before tensioning, to prevent tipping of the pontoon section (Fig. 1, pos. 1), water (ballast) must be poured into its compartments in the volume, according to previously performed calculations.

Thus, the claimed technical result, which consists in eliminating the need to install electric winches on the foundation, is achieved.
