Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.

1-3, a crane ground beam with anti-collision mechanical limiting comprises a ground beam 2, wherein crane wheels 5 are arranged at the lower part of the ground beam 2, the crane wheels 5 are connected with an output shaft of a driving motor 4, and the driving motor 4 can drive the crane wheels 5 to rotate so as to achieve the purpose of crane walking. The ground beam 2 is provided with a rail clamping device 3, the rail clamping device 3 can keep the crane wheels 5 to safely run on the rail mountain, and the driving motor 4 is connected with the limit switch 13 in series.

The axial tip of the ground beam 2 all is equipped with the spacing 1 of anticollision machinery, the spacing 1 of anticollision machinery includes mounting panel 11 and anticollision barrier 12, mounting panel 11 is fixed on the terminal surface of ground beam 2, the ascending square groove 14 of an opening, a limit switch 13 are all fixed to the front and back side of mounting panel 11, anticollision barrier 12 is the U type, in the cell body that its both ends all are equipped with square groove 14, and hinge together with square groove 14 through round pin axle 15, the side of square groove 14 is equipped with arc hole 16, be equipped with stopper 17 in the arc hole 16, stopper 17 is fixed on anticollision barrier 12.

For the sake of firmness, the mounting plate 11 is fixed to the end face of the ground beam 2 by bolts.

The working principle is as follows:

during installation, both ends of the ground beam 2 are provided with anti-collision mechanical limiting parts 1, so that both directions can be protected.

During normal running, the outermost contour of the ground beam 2 is the anti-collision guardrail 12, the anti-collision guardrail 12 lies in the groove body of the square groove 14 by means of gravity, the limiting block 17 is located at the lowest position of the arc-shaped hole 16, and the anti-collision guardrail 12 is at the lower limit position.

Both limit switches 13 are in the energized state, and the driving motor 4 can be energized, which can drive the crane wheels 5 to rotate, so that the crane can walk normally.

In case of an obstacle, the obstacle collides with the crash barrier 12, so that the crash barrier 12 rotates upwards along the pin shaft 15 (clockwise in fig. 3), meanwhile, the limiting block 17 moves to the highest position of the arc hole 16, when the crash barrier 12 touches the limit switch actuating head 131 of the limit switch 13, the limit switch 13 is powered off, the driving motor 4 is not powered on, and the crane is stopped.

Meanwhile, in order to prevent the limit switch actuating head 131 from being struck excessively, when the stopper 17 moves to the highest position of the arc-shaped hole 16 (see fig. 4), the crash barrier 12 cannot be rotated upward along the pin 15 any more to protect the limit switch 13.

When the obstacle is removed, the crash barrier 12 rotates downward (counterclockwise in fig. 3) along the pin 15, the limit switch 13 is in the energized state again, and the crane travels normally.

See the prior art for others.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
