SU66714A1 - A transfer device for transferring bridge cranes from one span to another, parallel to the span - Google Patents

Description

In large workshops consisting of several parallel spans of the same width, installation of separate bridge cranes in each span can be avoided if you ensure that the installed cranes are sufficiently convenient to move to any span. In the event that the edges are set. in each span, it is also advisable to: sometimes give an additional crane to a rabbit to replace the crane that is under repair .e and for the time being (nn strengthening the lifting means of the span.

The idea of transfer devices for the transfer of bridge cranes from one flight to a flight parallel to it. With half a half-semi-subsidiary auxiliary cranes, moving into another direction, a lime.

According to the invention, the crane beam and the semi-portal crane is located above the crane tracks of bridge cranes, which allows passage of cranes under it to be transferred. Such a structure provides a convenient transfer of cranes, even with a load or with a gripping device, mounted extremely.

FIG. 1 shows a cross-section along the line A-A (in Fig. 3) of a multi-span workshop equipped with a bridge (and K; wound% and; Fig. 2 is a longitudinal section of the workshop in Fig. 1; Fig. 3 is its plan; phpg. 4 - section of a single span of the line B-B (in Fig. 2); Fig. 5 - section of a transverse span; Fig. 6 - section along the line B-B (in Fig. 5); Fig. 7 - the same in a different design Fig. 8 is a longitudinal section of a part of the shop with a transfer device in another design.

AlocTOBbie cranes / relocation OP-s in 2 spans of the same width across the crane gantry rail m -3. In the transverse span; e 4 is installed a semi-portal crane 5, onepTbiJi foot 6 on the crane rail 7, laid at the level of the floor of the span 4, and slider S on the crane beam 9, mounted above the crane tracks 5. On the semi-portal crane 5, beams 10, distance between which the distance between the crane runways 5. from the cranes / can be inserted on the installed span of span 2, the semi-mortal crane and then moved along with the antenna to any other

span and entered in the aftermath. Crane beam 9 is mounted on tako: M | level that allows the passage underneath the crane. Leg 6 may be located on the side of the wall of the transverse flight 4 (Fig. 2) or from the side of the flight 2 (Fig. 8). A special device, not shown in the drawing, serves to bridge the gap between the rail elements laid on the rails 10 and on the subrack ways 5, as well as to fix the semi-portal at the moment when the bridge crane passes to it.

PRED Ml et t invention

 A radar device for moving light cranes from one span to another, parallel to it is a span using a semi-crank crane, characterized in that the crane beam of a semi-portal crank is located above the frame of the bridge cranes and pritol at such a level that allows for bridge cranes to be transferred cranes.
