Description

1.12

The invention relates to the construction of 1C1I crane tracks used in construction, mainly shops of ferrous and nonferrous metallurgy.

The purpose of the invention is to increase endurance and stability.

Figure 1 shows the device, a general view; in fig. 2 is a view A of FIG.

The crane track contains an I-beam crane beam 1, on which a rail 3 is fastened with the help of kpemmny rail fasteners 2. The rail fastening 2 includes an elastic., T-shaped flat from one end and a tubular terminal from the other end 4, anchoring elements 5 with T- shaped ends b and connecting them, plates 7 with oval holes. In the installed form, the terminal 4 with one end rests on the rail foot 3 and the other end through the eccentric 8 contacts with the upper flange 9 of the beam t. Between the upper flange of the beam 1 and its wall 10, which is made with a longitudinal corrugation, lining 11 1 is installed - shaped like a symmetrical longitudinal axis of the beam. The upper end of each pad 11 rests on the lower surface of the upper flange 9 and is connected to terminal 4 of the rail fastening by means of an anchor element 5 placed in a hole that is made in the upper flange of the beam 1.

The assembly of the device is as follows.

An eccentric 8 is put on the terminal 2 and is pinned with the cotter pin 12. The terminal 2 is supported at one end on the VIDA base

five

rail 3, and eccentric - on the top shelf 9 beams. The anchoring elements 5 pass through the oval holes in the plates 7 and the upper shelf 9, rotate them 90 °, orient the T-shaped shanks of the plates 7 across the oval holes, and lay down the plate 6 located under the upper shelf 9 of the beam. Enter t

the upper end of the lining 11 into the space between the upper shelf 9 and the plate 6. Pass the bolt 13 through the holes in symmetrically located relative to the vertical

the axles of the plates 11 and in the wall 10 of the beam, screw the nut on it and tighten it until it contacts and tight contact between the lower ends of the plates 11 and the wall 10 of the beam. Then

wedge the ends of the 14 terminals, turn the eccentrics 8 by 180 ° and fix the fastener in a tense state.

In case of transverse torsion of the upper side, the moment is perceived by the fastening terminals and is elastically transmitted through the / -shaped lining, forming a closed triangular 3 wall of the beam near its neutral axis, the stress zone of the upper transverse beam seam. Under the action of a vertical concentrated force, the curvature of the corrugations of the wall increases

The local compressive stresses are distributed over a greater length of the beam wall and, as a result, the magnitude of the local stresses is reduced.
