SU436012A1 - DEVICE FOR INSTALLATION OF TRUCK TROLLEY BRIDGE CRANE - Google Patents

Description

one

The proposed device relates to the field of load-lifting mechanisms.

Devices are known for mounting bridge wagon bogies containing a metal construction with a dead bolt supporting the main beams of the bridge, carrying a load-lifting unit.

The drawbacks of the known devices are their limited use depending on various installation conditions.

In order to expand the possibility of using the device for installation in enclosed structures on cranes of various capacities in the proposed device, the metalwork is supported on the main beams of the bridge made in the form of a portal with crawlers with external and internal stops fixed on them and resting on the main beams of the bridge beams . In addition, the rollers can be made eaten.

FIG. 1 schematically shows the proposed device when lifting a cargo trolley, a general view; in fig. 2 - the same, the truck in the design position; in fig. 3 - the same, side view; in fig. 4 - unit I installation of rollers on the main beam of the bridge crane; in fig. 5 shows an arrow A in FIG. four.

The device contains a metal structure 1 with a polypath 2 suspended to it in the upper part. On the supporting part of the metal structure 1, guides 3 are installed, along the edges of which external lugs 4 and internal lugs 5 are installed to fix the device to the main beams of the bridge crane. The outer stops are spaced from each other at a distance corresponding to the distance between the main beams of the crane bridge on the outside for free lifting between the load carriage; the internal stops are spaced from each other at a distance corresponding to the design distance between the main beams of the bridge on the inner side. On the main beams of the bridge, the rollers 6 are fixed in pairs along their vertical axis, while the plane of rotation of their legal structure is the longitudinal axis of the bridge. The rollers 6 are set apart from each other at a distance corresponding to the size of the metal structure 1 along the axes of the guides 3. The fastening of the rollers 6 to the main beams of the bridge is made removable.

The proposed device works as follows.

Using the chain pulley 2, lift the trolley to a level above the rail head of the main beams of the bridge, then pull down the main beams of the bridge, while the metal structure 1 with the RISE trolley rolls at 1 point, the power of the guides 3 on the roller 6, then the trolley is installed position.

Subject invention

1. A device for mounting a cargo carriage of a bridge edge containing a metal structure supported on the main beams of a bridge with a bolt carrying a lifting member, which is stark because, in order to increase the possibility of its use during installation in enclosed structures on cranes of various capacities, is supported by the main bridge beams The metal structure is designed as a portal with guides with outer and inner unors fixed on them and supported on pairs of rollers mounted on the main beams of the bridge.

2. IHO device n. 1, characterized in that the rollers are removable.
