Bridge ladder buffer device and bridge ladder with buffer function

Abstract

The invention discloses a bridge ladder buffer device. According to the bridge ladder buffer device, a lap joint target includes but not limited to various offshore platforms, and by using the bufferdevice, impact to a bridge ladder, which is resulted when the lower surface of the bridge ladder contacts the upper surface of the lap joint target in the bridge ladder descending process, can be effectively alleviated, so that the service life of the bridge ladder can be prolonged. In addition, when the included angle between the bridge ladder and the upper surface of the lap joint target is changed, a vertical buffer device is rotated around a rotating shaft, then good contact of the lower surface of the bridge ladder buffer device with the upper surface of the lap joint target can be ensured, and the security of the bridge ladder in the use process can be improved. In addition, a pressure value which is transmitted from a monitoring data transmission device and acquired by using a positive pressure sensor can be acquired by using monitoring equipment by an operator, if the pressure value is within a preset security range, the bridge ladder is in stable lap joint and can be used normally at the moment, and security accidents caused by unstable lap joint of the bridge ladder can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of landing on water, in particular to a bridge ladder buffer device and a bridge ladder with a buffer function. Background technique [0002] When performing regular maintenance or fault repairs on offshore wind turbines, workers need to land on the platform of the offshore wind turbines to enter the interior of the nacelle for maintenance or repairs. Offshore drilling platforms also often need to replenish or relocate supplies by offshore supply ships. The offshore platform and the offshore supply ship are connected by a bridge ladder, so as to carry out the transportation of personnel and materials. The bridge ladder is controlled by the operator. The bridge ladder is lifted first, then rotated to a suitable posture, and then lowered, so as to overlap between the offshore platform and the ship. Due to the heavy weight of the bridge ladder, when one end of the bridge ladder overlaps the platform and colli...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of the bridge ladder, when one end of the bridge ladder overlaps the platform and collides with the platform, it is easy to cause damage to the bridge ladder, thereby shortening the service life of the bridge ladder; The angle between the bridge ladder and the platform will change, which will easily cause the bridge ladder to be unstable and cause safety hazards
