Description

The utility model relates to crossing and bridge facilities for building a bridge across water and dry valley barriers, and specifically to the hulls of universal tank bridge layers.

A well-known body of a bridgelayer (see the Manual on the material and operation of the tank bridgelayer MTU-20,1969, p. 37), including a self-propelled five-bearing chassis, a laying mechanism and a two-track superstructure of the bridge, each track of which consists of a middle section and pivotally connected to it end sections.

The disadvantage of this bridge layer is the insufficient length of the bridge block, which is 20 m, the narrow gauge carriageway of the bridge with the inter-gauge gap, which limits the speed of military equipment and, as a result, its low throughput.

A crossing and bridge means is known - the MTU-72 bridge layer (see "MTU-72 bridge layer". Technical description. S. 1, 2, 9, 21, 22, 24-28, 160, 162, 163, 165, 166, 168 , 172, Fig. 3. 5, 14.7), containing an armored bridge-laying machine made on a six-support tank chassis, a retractable two-track bridge block with middle and end sections, a front support in the form of hydraulically driven bulldozer equipment, a rear support with a bridge block locking device on stern of the machine in transport position, opening mechanisms and mechanisms for connecting sections of the bridge block, stacking mechanism, including a stacking frame driven by hydraulic cylinders and a mechanism for moving the bridge block driven by hydraulic motors.

This technical solution in its functional purpose and in its technical essence is the closest to the claimed one and is taken as a prototype.

However, the MTU-72 bridgelayer does not provide bridge guidance on wide sections of the barrier, because the length of the bridge block is 20 m.

The technical result, to which the utility model is directed, is the implementation of the hull of a universal tank bridge layer on a seven-bearing chassis of increased rigidity to provide the possibility of transporting and guiding a bridge block of increased length up to 25-27 m.

The technical result is achieved by the fact that the body of the universal tank bridge layer, containing armored sides, a bottom, a roof, a stern sheet, a control compartment, a middle compartment, an engine compartment, a rear support, according to the utility model, is made with the possibility of its installation on a seven-support undercarriage, a control compartment located in the bow above the first and second track rollers, the middle compartment is box-shaped with a reinforcement belt in the form of transverse T-shaped I-beam frames connecting the roof with the sides and the bottom through a transverse welded bottom beam rigidly connected to the specified bottom and brackets for attaching the hydraulic cylinders of the aiming beams.

At the same time, a door for embarkation/disembarkation of the crew is made in the forward part of the hull.

At the same time, in the forward part of the hull, protective electrically heated glasses of the crew are installed.

At the same time, the roof of the middle compartment of the hull is equipped with emergency and assembly-technological hatches, and the bottom of the hull is equipped with an additional emergency hatch.

The analysis of the distinguishing features showed the following:

making the body with the possibility of its installation on a seven-bearing undercarriage, allows you to increase the load on the undercarriage from the bridge block of increased length to 25-27 m and evenly distribute it on the undercarriage of the bridgelayer;

the location of the control compartment in the forward part of the hull above the first and second track rollers, contribute to the release of the internal space of the middle part for the rational placement of the reinforcement belt, and also improves the situational awareness of the crew through protective electrically heated windows when pointing the bridge block and when removing its obstacles, optimally place the internal equipment;

the implementation of the middle compartment of a box-shaped form with a reinforcement belt in the form of transverse T-shaped I-beam frames connecting the roof with the sides and the bottom through the transverse welded bottom beam, rigidly connected to the specified bottom and brackets for fastening the hydraulic cylinders of the aiming beam, makes it possible to increase the longitudinal and transverse rigidity of the bridge layer body at guiding and removing a bridge block of increased length up to 25-27 m and weighing up to 13 tons;

the implementation of the door in the bow of the hull reduces the time of boarding / disembarking the crew;

installation of protective (bulletproof) electric heating glasses in the forward part of the hull provides bulletproof protection of the crew equally with the hull;

implementation of an emergency hatch in the roof of the middle compartment, allows the crew to leave the bridgelayer in case of a deep landing in the track of the undercarriage and the inability to use the emergency hatch in the bottom, as well as in case of impossibility to use the door in the bow of the hull;

the implementation of an additional emergency hatch in the bottom of the hull allows the crew to leave the bridgelayer in case it capsizes onto the roof of the hull.

The essence of the utility model is illustrated by drawings, where

in fig. 1 - longitudinal section of the body;

in fig. 2 - general view of the hull, top view;

in fig. 3 - cross section of the body A-A along the reinforcement belt;

in fig. 4 - longitudinal section of the body B-B along the reinforcement belt.

The inventive body 1 of the universal tank bridgelayer (see Fig. 1-4) is made highly protected from armored steel with the possibility of its installation on the seven-support undercarriage 2 to ensure the reserve of longitudinal and transverse stability of the bridgelayer when installed on an obstacle of a bridge block of increased length up to 25-27 m .

The control compartment 3 is located above the first and second road wheels to improve the situational awareness of the crew through the protective electrically heated glass when pointing the bridge block and when removing its obstacles, and also help free up the internal space of the middle part for the rational placement of internal equipment, in the rear wall 4 of the control compartment 3 a manhole 5 was made for servicing the systems and units of the middle compartment 6, in the upper front sheet 7 of the body 1 a door 8 was made for boarding/disembarking the crew and two rectangular openings 9 for installing protective (bulletproof) electric heating glasses.

An emergency hatch 10 and two holes 11 for hydraulic cylinders for controlling the aiming beam, as well as an assembly and technological hatch 12 for mounting and dismantling units and assemblies of the middle compartment 6 are made in the roof of the hull behind the habitable compartment. An additional emergency hatch is made in the bottom 13 of the hull near the engine bulkhead. fourteen.

The upper front sheet 7 of the bridge layer body in the upper part has a bend at an angle of 15° from the vertical to provide more comfortable observation through the protective glass both when the bridge layer moves and when the bridge is taken from an obstacle. The middle section 6 of the hull 1 is box-shaped with a reinforcement belt 15 rigidly connecting the bottom, left and right sides and the roof of the hull, which is a transverse T-shaped I-beam 16 connecting the roof with the sides and the bottom 13 through the transverse welded bottom beam 17, rigidly connected with the bottom 13 and the lugs 18 of the attachment of the hydraulic cylinders of the aiming beam, which increases the rigidity of the body 1 for the perception of dynamic loads when pointing and taking the bridge block. Moreover, body 1 provides armor protection against the B-32 armor-piercing incendiary bullet of 12.7 mm caliber of all vital units and systems of the bridgelayer.

When pointing the bridge block at an obstacle, stresses arise in the hull 1, which are perceived (compensated) by the reinforcement belt 15, which prevents the deformation (deflection) of the bottom 13. This is ensured by the transverse welded bottom beam 17, which in turn redistributes the resulting load on the roof and sides of the hull 1 by means of T-shaped I-beams.

Thus, the proposed technical solution makes it possible to make the body of a universal tank bridge layer on a seven-bearing chassis of increased rigidity to provide the possibility of transporting and guiding a bridge block of increased length up to 25-27 m.
