Description

Invention otnh: itc to the bridge-crossing technique and can be used in the construction of mechanized bridges. Iazesten bridging machine, including base machine, span, umfi ™ kirno attached to the base machine, a lifting frame with a strut, and hydraulic hooks for turning the lifting frame, connected by means of a rope, working with a working tool, working in a working place, working in a working place. The bridge laying consists in considerable material consumption and complexity of the rotation of the HIX) bracket, due to the considerable length of the latter to ensure the reversal angle of the span and the presence of a hydrolispaste, as well as the lack of reliability of its operation when raising and lowering the span due to the presence of additional kinet / aft links, namely hydropolispaste embedded in the swivel bracket. The closest to the proposed bridge is a bridge laying machine, including a base machine, a propet design, a cable winches with a winch, hinged frame on the chassis of the machine, and lifting frames of the lift frame to the hingedly mounted on the lifting frame, swivel brackets and idle brackets on the lifting frame. The cable system is fixed at the remote end of the span | 2. The drawbacks of the bridging bridge are the insufficient operation of the swivel brackets and the considerable time of disconnecting and attaching the span to the main machine. The purpose of the invention. - Improving the reliability of the work-s pszhortoy6.1x kuyenshteynov and reducing the time to disconnect and

the attachment of the span to the machine.

The delivered chain is achieved by the fact that in the bridge laying machine, including the base machine, the span, the tandem and linkage system with the winch, the lifting frame and the hydraulic cylinders of turning the lifting frame and the swivel brackets fixed on it to the chassis of the machine are detachable a span structure, each swivel bracket is equipped on a hinged end mounted on the swivel frame with a fork forks with a locking retractable pin to which the end of the span structure is attached via an ear and the other end is equipped with a deflector reinforced on it by means of the supporting element and is made with a SKEET slot for passing the dump and a cable system in contact with the deflecting unit of the rope, and the span structure is provided in the vertical plane of the through slot with a socket for fixing the hook of the rope until the span is detached building from the base machine.

FIG. 1 shows a power packer, general view; in fig. 2 shows the node J in FIG. FIG. 3 shows section A-A in FIG. 2

The bridgewalker comprises a base machine 1, a span structure 2, a cable-block system containing, for example, rope 3 and blocks 4 and 5, a winch 6 hinged to the machine chassis

1 lifting frame 7 and hydraulic cylinders 8 of the lifting frame of the lifting frame and psyuornye brackets 9 hinged on it, detachably connected to the propeton structure 2.

Each pszhorotnyy bracket 9 is provided on a reinforced by means of a hinge 10 on the pszhorotnyy frame with a fork end 11 with locking pin 12 to which through the ear

13 is detachably attached to the end of the span 2, and at the other end the swiveling kroshpteyn is provided with reinforced on it by means of supporting elements

14 the deflecting unit 15 and is made with a through groove 16 for the passage of the hook 17 and the rope 3 of the cable-blocking system in contact with the blade of the 15th block 15. At the same time the span

2 is provided in the vertical plane of the through groove 16 with a socket 18 for fixing the hook 17 of the rope before disconnecting the span from the base machine 1.

To lower the end of the span 2 onto the obstacle, the hook 18 is pulled into the nest 18 by means of the winch 6 and the locking pin 12 of the fork 11 is pulled and releasing the hook 13 of the span 2. Then, winding the rope 3 from the winch drum 6 t lowering the end of the flying structure with the support resting on the ground or a previously installed support (not shown), after which the hook 17 is removed from the socket 18 and the superstructure is disconnected from the base machine.

To raise and secure the end of the span on the base machine 1, each pn-rotary bracket 9 is lowered onto the span, the rope with hook 17 is driven through the through groove 16 and installed in slot 18, and the rope is inserted in the creek of the deflecting unit 15. Zata the rope is tightened together with the span of the span until the ear hole 13 is aligned with the locking pin 12, which connects the end of the span with the fork 11 of the swing arm 9 attached by means of the hinge 10 to the lifting frame 7 of the bridge chica.
