Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, a running gear of cranes. The purpose of the invention is to increase reliability. The mount of the traveling wheel to the crane contains a shaft 2, on which a running wheel 1 with a spherical eccentric sleeve 12 is placed. On the front part of the sleeve 12 and the front part of the shaft 2 radial direction grooves are made to place the protrusion 15 of the fixing cap 16 in them. the circumference is fitted with adjusting bolts 18, which abut against the end surface of the housing 11 of the wheel 1 and serve to set the wheel housing to the desired position relative to the axis of the shaft 2. The locking cover 16 is attached to the end portion of the wheel and by centering bolts 17. 7 yl.

Description

FIELD OF THE INVENTION The invention relates to a lifting machinery industry, namely, a running gear of bridge cranes.

The purpose of the invention is to increase reliability.

FIG. 1 shows a crane with a moving mechanism, a general view; in fig. 2 - the same, front view; on - section A-A in FIG. 2;

4- section BB in FIG. 2;

5 is a view of B in FIG. four; in fig. 6 is a view of FIG. four; FIG. 7 shows the node I; FIG. one.

FIG. 3 in FIG.

The mount of the traveling wheel to the crane consists of running wheels 1 mounted on shafts 2 coaxially with span beams 3 crane bridges interconnected by means of beams 4 and driven by a movement mechanism comprising engine 5, gearbox 6, pulley pulley 7, mounted on the output shaft 8, and a rope 9 wound on a friction pulley with the required number of turns and ends fixed at the beginning and end of the span with a known way of a rope stretching compensator, the running wheel contains rolling bearings 10, rings mounted on the housing And, consisting of two parts connected by clamping bolts (conventionally not shown), a spherical eccentric bushing 12 mating with the housing along the outer spherical surface mounted on the spike 13 of the shaft 2 and having on the end grooves 14 of the radial the directions in which the protrusion 15 of the fixing cover 16, which is connected to the stud by the bolt 17, is installed. Adjusting bolts 18 are located on the fixing cover, which serve to adjust the position of the bearing housing relative to the shaft axis. At the end of the travel wheel, bolts 19 secure the cover 20. Shaft 2 is welded to the span

beam 3 through the lining 21. On the side opposite to the cover 20, a through cover 22 is installed on the running wheel.

The device works as follows.

On the spherical eccentric sleeve 12 from two sides install the housing 11. In the tire running; the wheels 1 mount the bearings 10; the tire assembled in this way is mounted on the bearing housing 11, a through cover 22 is connected. Then the running wheel assembly is mounted on the shaft spike 2. Since the shaft axis 2 and the axis of the passage beam do not coincide due to inaccuracy of installation, then, in order to ensure alignment, the spherical eccentric bushing is turned to the required position, in which coaxiality will be ensured, after which the eccentric bushing is fixed by the fixing cap 16 with the help of a bolt 17. By adjusting the bolts 18 after the fixing cap 16 is installed. Upon alignment, the cap 20 is attached and the bolts 19 are attached to the tires of the traveling wheel 1. The crane is moved along the crane tracks using the drive mechanism friction between the turns of the rope 9 and the pulley 7 friction.

Claims (1)

Invention Formula I The mount of the traveling wheel to the crane, containing at one end a shaft connected to the metal construction of the crane, on which a sleeve is fixed with a spherical outer surface connected to the counter surface of the yoke associated with the driving wheel, characterized in that, in order to improve reliability, it is equipped with a fixing lid, with at least three adjustment bolts, on the front part of which a ledge is made, the sleeve is made eccentric and with grooves on its outer front part directed to the shaft axis at the front hour Which is made diametrically groove, and the locking cover is fixed on the end of the shaft with its protrusion in one of the grooves of the specified sleeve and in the groove of the shaft, and the adjusting bolts are evenly placed around the circumference, the center of which is located on the axis of the shaft .
