RU162457U1 - SOFT PONTON FOR CLEANING THE CHANNEL FROM DAMAGED CONSTRUCTIONS - Google Patents

Abstract

A soft pontoon for clearing the riverbed from collapsed structures, consisting of a shell made of two layers of fabric, stitched with ribbons of rubberized material, having a cylindrical shape, characterized in that the soft pontoon is equipped with a protective casing and a mechanism for selecting the depth of immersion.

Description

The utility model relates to bridge construction, and more specifically to the restoration of railway bridges along the old axis.

A soft ship-lifting pontoon is known from the prior art, having a cylindrical shape and consisting of a shell made of two layers of fabric stitched with ribbons of rubberized material, on which a belt is mounted with eyes fixed to it for attaching hangers assembled in the lower part for connection with rigging brace. (Salvage property and means of the navy. Part 3. Special salvage property and means of ships and units of search and rescue support of the Navy. Publishing house “Document”, Moscow, 2003, p. 261.)

The disadvantages of this device is the inability to lift or reduce the weight of the structure with a relatively small depth of water, eliminating the use of a soft pontoon on top of the structure.

The problem to which the claimed utility model is directed is the possibility of using soft pontoons to lift or reduce the weight of the collapsed span, with a water depth that does not allow the use of pontoons from above the structure.

This problem is solved due to the work of soft pontoons inside the collapsed structure. Lowering the soft pontoon to the required depth is ensured by equipping it with a mechanism for selecting the depth of immersion. To avoid damage to the soft pontoons from above, it is equipped with a protective casing. To ensure mobility and autonomy, a floating support can be attached to soft cylindrical pontoons, consisting of a section of the pontoon НЖМ 56 (it is a box and consists of a frame and sheathing made of sheet steel. To increase unsinkability it is divided into four compartments by transverse bulkheads) with a self-propelled section of NZhM 56 property (used as a pusher boat when towing pontoons, has a propeller group, steering and equipment necessary for a self-propelled riverboat), equipped with a pumping unit Iya air. Pontoons are cylindrical can be single and type-setting. Structures of more than one soft pontoon must have, in addition to the above connection, for their connection with each other.

The technical result provided by the given set of features is the possibility of using soft pontoons for lifting collapsed spans with their placement inside the structure.

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

Figure 1 Device for lifting or reducing the weight of a collapsed span.

A device for reducing the weight of collapsed spans consists of a floating support made of a non-self-propelled pontoon section of NZhM 56 -1 property and a self-propelled pontoon section (pusher boat) of NZhM 56 -2 property. An installation for pumping air -3 and a mechanism for choosing the depth of immersion of the pontoon -4 are fixed on the floating support. Soft cylindrical pontoons -5 protected from above by a protective casing -6 are attached to the mechanism for selecting the depth of immersion of the pontoon. The distance between the axes of the trusses of spans -7 is in the range of 5.6-5.8 m. Under this size, the author suggested using two soft cylindrical pontoons -5 6 m long, width and height, taking into account the harness - 2.5 m, respectively; 3.5 m each.

Figure 2 Mechanism for selecting the depth of immersion of the pontoon.

The mechanism for choosing the depth of immersion of the pontoon is assembled as follows:

After examining the collapsed structure and determining the necessary immersion depth of the soft pontoons, the assembly of the mechanism is carried out. To the non-self-propelled pontoon section -1, two vertical guides -8 are attached. Two horizontal guides -9 are attached to the vertical guides through the hinge, depending on the required depth. To hold the pontoon in a horizontal position, the guides are interconnected by flexible cables -10. A protective casing -6 is attached to the horizontal rails -9, and soft cylindrical pontoons -3 are attached to the protective casing. The device for pumping air -3 and soft pontoons are interconnected by swap hoses -11.

The device operates as follows. The initial position of the device - soft pontoons lowered (not inflated), are in a horizontal position. The floating support moves the pontoons into the collapsed structure, the air injection device delivers the necessary amount of air into the soft pontoons and the operation indicated in the flow chart is performed. This is either lifting one of the ends of the span, or reducing the weight of the span, to move it using other devices. Before pumping air into the pontoons, soft cylindrical flexible cables (Fig. 2, item 10) are disconnected.

Thus, the proposed device will reduce labor costs for lifting structures by eliminating slinging and reduce the time to perform multiple operations due to the mobility of the device.
