Description

one

The invention relates to lifting vehicles, in particular, load handling devices for lifting and tilting loads and can be used in construction for installing floor panels in the construction of large-panel buildings.

According to the main author. St. No. 612888 A traverse-turner is known, containing a suspension mechanism hung on a hook, made with an axis on which a beam is articulated with a shift relative to the center of gravity of the beam forming a double-arm lever til

A disadvantage of the known device is its limited functional capabilities, i.e. it is suitable for work only with products with asymmetrically arranged hanging loops.

The purpose of the invention is to enhance the operational capabilities of the traverse by providing turning

: - products with a symmetric position of the capture points relative to the center of the body of the product.

This goal is achieved in that the suspension is made of a composite of articulated links. FIG. 1 shows the proposed traverse when taking a product from a panel truck, general view; in fig. 2 the same, the product is raised and transferred to a horizontal position.

Traverse-tilter contains a suspension of two links 1 and 2 connected by a hinge 3, an axis 4 and a beam 5, made in the form of a two-arm, at the ends of which are fixed the slings 6 and 7 for gripping the panel 8.

The center of rotation of the beam 5 is displaced relative to the point of attachment of the suspension to the lifting mechanism by an amount sufficient to smoothly transfer the load to the horizontal position. To ensure the stability of the beam in the initial stage of lifting, a locking device is provided on the lower link 2 of the suspension (conventionally not shown in the drawing).

Adjustable pivot 3 below.

The locking device is made of a known construction, for example, in the form of a spring-loaded rod not fixed to the lower link,

automatically entering when fixing the beam in a vertical position in the hole, in the beam .. -. The traverse tilter works as follows. The hooks of the lines 6 and 7 are hooked to the special grippers installed in the upper and lower technological openings of the panel, which are in the vertical position or close to it (on the panel truck). . When lifting the panel8 from the panel truck, the top link 1 of the suspension takes up a vertical position, while the point of attachment of the suspension to the lifting mechanism under the force of the gravity of the panel 8 coincides with the line passing through the hinge 3 and the center of gravity of the inclined panel 8. In such a position, the tilt-bar together with the panel is raised above the farm of the panel truck. As soon as its bottom appears over the top of the cart panel, the decidable beams are released and the device is turned, and the crane operator by pushing the boom of the crane towards the installation site gives a push to the traverse tipping device. When the panel is lifted above the panel and the locking device is released, the beam 5 rotates together with the load about axis 4 (and n axis 4). By 180 °, as forming along a part of the surface two cones, their vertices converge in the center of The shaft, located on axis 4. Beam 5, as an obrazukd, describes that part of the surface that is opposite to the direction of rotation of the hook of the lifting mechanism. Under the force of gravity of the panel 8, transmitted through the slings of the b and 7 raznochlei beam, different torques appear in magnitude, under the action of which the beam 5 together with the panel 8 smoothly changes to a horizontal position (Fig. 2). The beam with the panel continues to rotate until Tiex, until the algebraic sum of the torques relative to the center of rotation of the beam becomes zero, in this position the point of attachment of the suspension to the lifting mechanism and the center of gravity of the panel are on the same vertical line. In the horizontal position, the panel is laid in the required place, the stroping is performed and the traverse is placed to the next panel. During the filing of the beam takes. vertical position, (short arm down) and locked with a locking device. Other products, such as beams, columns, piles, etc., have capture points (holes, loops, or hooks) that are symmetrically located relative to the center of gravity of the sheet. The formula of the invention Traverse tilter according to ed. ev No. 612888, characterized in that, in order to expand its fuci, of the national possibilities of ensuring the turning of products with a SIM metric arrangement of capture points relative to the center of gravity of the product, the suspension is made of a composite of articulated links.
