Description

The invention relates to load gripping devices and can be used to move flat loads, as well as “T” -, “P” -shaped loads for flat horizontal elements, for example formwork of monolithic floors, flooring panels, floor panels, balcony slabs, etc. .

The closest known technical solution is a traverse for moving the formwork of monolithic floors, containing a working body with a sling element made in the form of a prefabricated spatial structure of three spatial trusses, welded from tubular elements interconnected by detachable joints, with scarves and bolts, the lower spatial the truss is equipped with a stacked counterweight, and the sling element is installed on the upper spatial truss [1].

The disadvantages of the presented analogue are the absence of safety and fixing elements to prevent tearing and sliding of the load from the supporting surface of the lower truss, difficult balancing of the formwork and formwork shields with different sizes of a stacked counterweight, which excludes trim, but does not exclude roll, limited capabilities when transporting structures with vertical elements, due to the dimensions of the lower spatial truss.

The objective of the invention is to simplify balancing and securing the load on the beam, excluding roll, trim, breakage and slipping when moving loads of various sizes, including under overhanging structures.

The problem is solved by combining two flat frames consisting of upper, lower and vertical elements into a single spatial structure by means of three connections with a set of adjusting grooves on the bolts, where the upper elements are equipped with rocker arms with clamps fixed pivotally and mounting loops, and the lower ones removable stops installed in any of the holes in accordance with the dimensions of the cargo.

The proposed design is illustrated by drawings, where in Fig.1 shows a crosshead in a perspective view; figure 2 is a diagram of the installation of cargo with a horizontal flat element for overlapping on the example of a table formwork overlap; figure 3 - traverse in the transport position.

The traverse (Fig. 1) consists of two flat frames 1 connected in a spatial structure by ties 2 on bolts 3 through grooves 4. To fix the load 5 in the transport position, the frames 1 are equipped with articulated rocker arms 6 with clamps 7 on the axles 8 and mounting loops 9 , as well as removable stops 10, which together excludes the separation and sliding of the load 5 from the crosshead. For the uniformity of the slinging of loads of different widths, the width of the crosshead can be changed by bringing the flat frames 1 closer by a multiple of the pitch of the grooves 4 with the subsequent connection of the frames 1 and the ties 2 on the bolts 3. A safety removable stop depending on the length of the load can also be installed in any of the holes eleven.

A stable position of the traverse and the load is achieved when their center of gravity is located inside the quadrangle formed by the hooks 12 of the four-branch line 13. And spaced apart from each other frames allow you to move the loads for their flat horizontal elements, placing their vertical elements both inside (for a “T” -shaped ) and outside the frames (for the “P” -shaped).

The ability of the traverse to move goods under (or from under) overhanging structures is illustrated in figure 2, where as the load 5 presents the formwork table monolithic overlap 14.

The position of the traverse in the transport version is illustrated in figure 3, where the rocker arms 6 with clamps 7 are in a free balanced state, and the traverse is slinged for mounting loops 15 of the upper frame elements.

The inventive design of the traverse differs from analogues in the presence of two flat frames consisting of upper, lower and vertical elements, combined into a single spatial structure by means of three connections with a set of adjusting grooves on bolts, where the upper elements are equipped with rocker arms with clamps fixed pivotally, and mounting loops, and the lower ones - with removable stops installed in any of the holes corresponding to the length of the load, which together excludes the separation and sliding of the load from the beam, and stable The position of the traverse and the load is achieved when their center of gravity is located inside the quadrangle formed by the hooks of the four-branch line, which allows to do without additional balancing with a stacked counterweight, and the frames spaced apart by a multiple of the pitch of the grooves from each other allow expanding the capabilities of the traverse when transporting goods of the required size, for their flat horizontal elements by placing vertical elements inside or outside the frames.
