Abstract

1. A DEVICE FOR DISASSEMBLY OF ASSEMBLY PANTS, mainly collapsible temporary supports of the bridge, including a dual-console carrier beam and cable-and-block systems with drives, characterized in that, in order to ensure dismantling without using additional lifting means, the carrier beam is provided with longitudinal displacement guides, longitudinal displacement, and longitudinal displacement, it is equipped with guides for its removal, without the use of additional lifting equipment. The cable block systems are located on the console beams and are made in the form. tackles with sling loops; one of the tackles has a traverse, and its slinging loops are blocks through which the cable fixed with one end to the traverse and the other to the console of the bearing beam is retracted.

2. The device according to claim 1, of tl. It is due to the fact that the drives of the splinters are installed respectively on the opposite console of the supporting beam,

3. The device according to PP. 1 and 2, characterized in that the beam is provided with support elements arranged on its brackets in the form of boxes with elastic gaskets.

The invention relates to the construction, in particular to bridge construction, and can be used in the dismantling of mainly demountable temporary supports and similar structures. .. The closest to the invention according to the technical essence and the achievement of the MOMj result is a device for dismounting precast supports, including a two-console carrier beam and troso-blk systems with a drive, mI. . The disadvantage of this device lies in the impossibility with its help of dismantling the collapsible support under the already mounted span structure of the constructed bridge, which requires the use of attached lifting equipment when moving the device from support to support. In addition, it is not possible to change the cover in the space of the dismountable support elements when laying on vehicles. The aim of the invention is to provide dismantling without the use of additional lifting equipment. The goal is achieved by the fact that in the device for dismantling precast supports including a two-console carrier beam and troso-block systems with drives, the carrier beam is provided with longitudinal displacement guides, and the troso-block systems are located on the beam consoles and are in the form of pulley with slinging loops, one of the spares has a traverse, and its slinging loops are blocks through which the cable fixed with one end to the traverse is stored with the possibility of rolling, and the other is attached to the end of the supporting beam. In addition, the pulley drives are installed respectively on opposite consoles of the carrier beam. The beam is provided with supporting elements in the form of boxes with elastic gaskets placed on its brackets. FIG. i shows the device, a general view; in fig. 2 - the same, in the intermediate phase of dismantling the support; in fig. 3 - the same, at the time of laying the dismantled support element on the vehicle; in fig. 4, side view. The device contains a two-console carrier beam 1 with guides 2 rigidly attached to it. Poly-beams are placed on the console beams. 3 with slinging loops 4 and a tackle 5 with a cross-wire bis cable 7, stored through blocks 8 with the possibility of rolling over them; On blocks 8 there are slings 9 loops. Polyspasts 3 and 5 have actuators 10, which are located on the console of beam 1, and drive 10 of the polyspast 3 is located on the opposite console of beam 1, and drive 10 of the other polyspast - on the other opposite console. On the console beams in their lower part are placed the supporting elements 11, made in the form of boxes with elastic pro-laying. The device works as follows. Along the way the wheels 12, laid on the mounted span structure 13, the carrier beam 1 is moved to the position for dismantling the next support. The lifting loops 4 and 9 are fixed on the dismountable element 14. The dismountable element 14 is disconnected from the rest of the support 15. The tackles 3 and 5 are turned on and the dismountable element 14 is moved from the position in FIG. 1 through intermediate positions as in FIG. 2 to the position in FIG. 3. At the same time, in the case of various loads, the tackles 3 and 5 carrying the beam, leaning, rests on the support boxes 11; The slinging loops 4 and 9 are disconnected from element 14 and the tackles 3 and 5 are tightened. The device is ready to dismantle the next element. After dismantling the support in a known manner, the device is moved to the next support. This embodiment of the device provides for the dismantling of collapsible blocks of supports under mounted spans built

bridge and laying of the dismantled elements of the supports on the vehicle without the use of additional

lifting equipment while simplifying the production of works and ensuring the safety of operations.
