Problems solved by technology

However, during the hoisting process of the motor-driven rescue boat, due to problems such as the motor drive speed is too high and the rescue boat is not installed in place, it is easy to cause the boat body to shake severely due to the fast recovery speed of the rescue boat. Sometimes the rescue boat is also prone to violent collision with the jib to cause damage

Embodiment Construction

[0032] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0033] Such as Figure 1-5 As shown, a high-low speed automatic switching system used in the rescue boat recovery process includes a rotating boom 1 and a fixed boom 2. The fixed boom 2 includes an outer column 2-1 and an inner column 2-2. The inner column 2-2 is provided with a rotating shaft 3, and one end of the rotating boom 1 rotates around the rotating shaft 3 to realize the lowering and recovery of the rescue boat; the inner side of the outer column 2-1 is provided with a first limiter 4 and a limiter. The bumper 5, the limit bumper 5 is used to press the first limiter 4, the first limiter 4 is used to realize the high-speed recovery of the rescue boat...

Abstract

The invention relates to a high-low speed automatic switching system for a rescue boat recovery process and a switching method of the high-low speed automatic switching system. The system comprises arotary suspension arm (1) and a fixed arm frame (2), the fixed arm frame (2) comprises an outer stand column (2-1) and an inner stand column (2-2), a rotary shaft (3) is arranged on the inner stand column (2-2) in an extending mode, and one end of the rotary suspension arm (1) rotates around the rotary shaft (3) so that the rescue boat can be lowered and recycled. The system is characterized in that a first limiting device (4) and a limiting collision block (5) are arranged on the inner side of the outer stand column (2-1), and a second limiting device (6) is arranged on the inner side of theinner stand column (2-2); when the rescue boat is electrically recycled, the rescue boat is lifted at a high speed and then recycled to a preset position at a low speed, it is guaranteed that the whole process is carried out stably, the situation that the boat body shakes seriously due to the too high recycling speed is avoided, and meanwhile severe collision between the rescue boat and the fixedarm frame is avoided when the rescue boat is folded and unfolded.

Description

technical field [0001] The invention relates to the technical field of rescue boat recovery, in particular to a high-low speed automatic switching system and a switching method used in the rescue boat recovery process. Background technique [0002] According to the requirements of the "International Convention for the Safety of Life at Sea" and my country's "Code for Life-Saving Equipment for Sea-going Ships", the release of the rescue boat must meet the following conditions: that is, the mother ship will release the rescue boat within a period of no more than 5 minutes when the power is lost. to the sea; and the recovery of the rescue boat requires meeting the conditions: that is, the rescue boat is lifted from the sea at a speed of not less than 18 m / min. Therefore, in general, the rescue boat is lowered by its own gravity, and the recovery is lifted by a driving device such as a motor. However, during the hoisting process of the motor-driven rescue boat, due to problems s...
