Definitions
- the present invention relates to a crane in which a crane body moves as a traveling device travels along a rail.
- the container crane is a bridge-type crane installed on the quay of the container terminal, has a lifting tool for container handling, and can travel on a track.
- the traveling on the rails of the container crane is performed by a traveling device including wheels.
- the container crane is fixed to the rail or the ground by the anti-runaway device so that the container crane does not travel along the rail when the traveling is stopped or the operation is stopped due to a gust or the like.
- Examples of the runaway prevention device include a rail clamp that sandwiches the rail, a device that holds the rail from the top (hereinafter also referred to as rail brake), a mechanical brake for the wheel, an electric motor brake, and an anchor device that can be fixed to the ground.
- container cranes may be provided with a seismic isolation device between the crane body and the traveling device to prevent collapse due to an earthquake.
- Patent Document 1 discloses a technique related to a vibration isolator that prevents the crane from being derailed due to an earthquake.
- the collapse of container cranes due to earthquakes is caused by the fact that the wheels are lifted by the seismic force from the direction perpendicular to the run (perpendicular to the direction of rail extension) and the container crane is derailed from the rails. Therefore, the seismic isolation device provided between the crane main body and the traveling device reduces the seismic force in the direction perpendicular to the traveling direction and prevents the container crane from being derailed.
- the seismic force in the traveling direction is not a seismic isolation device, but sliding friction between the traveling device (wheel) of the container crane and the rail or a brake provided on the wheel drive unit. This friction absorbs and relieves vibration. If the container crane is running, etc. and is not fixed to the rail or ground by the escape prevention device, there is no limit on the movable range of the traveling device, but if the traveling is stopped and fixed, the movement of the traveling device Is limited and cannot absorb and relieve vibration sufficiently. Therefore, a large impact force is applied to the container crane, which may cause damage.
- the rail clamp is connected to the traveling device via a connecting member.
- the connecting member is provided with a shear pin, and the shear pin breaks when a predetermined seismic force acts in the traveling direction. Therefore, until the shear pin breaks, the crane resists sliding in the traveling direction by the rail clamp. In addition, after the shear pin breaks, a seismic isolation action occurs due to sliding friction between the wheel and the rail, but the rail clamp is still fixed to the rail. For this reason, depending on the amount of movement of the crane on the rail, the traveling device and the rail clamp may come into contact with each other, and the rail clamp may be damaged.

You can get directional seismic isolation. Further, the seismic isolation device 13 also obtains seismic isolation in the direction perpendicular to the traveling direction. Conventionally, seismic isolation in the direction perpendicular to the traveling direction was obtained, and sufficient seismic isolation in the traveling direction was not obtained. Therefore, when the seismic force was input in the traveling direction or in the oblique direction, the crane body 1 was twisted and traveled. Deformation in the perpendicular direction occurred.
- a special device such as the seismic isolation device 13 is not required, and the shear pin 24 and the connecting portion 8 of the seismic isolation device 13 are not required. It is only necessary to change the control logic of the rail clamp 3, the rail brake 4 and the anchor device 5 while providing a device for detecting the release of the shear pin and a device for forcibly releasing the shear pin 24, and the cost is low. Furthermore, even when an existing crane is improved, no large-scale improvement is required, and the improvement can be made in a short period of time and at a low cost.
- the escape prevention device such as the rail clamp 3 may be released using vibration detection by a seismometer or a weight.
- detection by a seismometer or a weight may cause a false detection due to a shake other than an earthquake, which may cause a problem that escape prevention may be canceled unexpectedly due to the false detection.
- a device other than the seismic isolation device such as a seismometer and a weight, an extra cost is required, resulting in an uneconomical configuration.
- shear pin 24 of the seismic isolation device 13 or the shear pin of the connecting portion 8 is not cut by the wind during normal work. Therefore, by detecting the earthquake using the shear pin 24 of the seismic isolation device 13 or the shear pin of the connecting portion 8, release of the escape prevention device due to erroneous detection can be avoided.
- the runaway prevention device automatically works, and the container crane is fixed to the rail or the ground.
- the escape prevention device does not work or even if the escape prevention device works, It is desirable that the escape prevention device is released by detecting an earthquake.
