Problems solved by technology

The hydraulic towing winch is located in the middle of the ship. The towing distance of the anchor chain is more than 30 meters long, and the weight is heavy. The use of conventional chain guides can no longer guarantee the orderly and smooth lifting and throwing of the anchor chain. Therefore, a corresponding chain guide device is needed. To meet the above conditions of long towing distance and heavy weight

Embodiment 1

[0027] The anchor chain 1 passes through the stern drum 13 and the shark jaw 14 of the stern and reaches the hydraulic towing winch 2 at the midship position of the main deck through the wooden deck area, and guides the anchor chain 1 to its two sides through the left and right anchor chain wheels 3 on the hydraulic towing winch 2 The anchor chain pipe 4 enters the chain locker, which is the anchor operation process, otherwise it is the anchor operation.

[0028] If the anchor chain 1 enters the chain from the upper end of the anchor chain wheel 3, under the influence of the height of the anchor chain wheel 3 and the weight of the anchor chain 1, there will be a large swing, which is difficult to control and is extremely unsafe. figure 2 In the shown chain feeding mode, the anchor chain 1 enters the chain from the lower end of the anchor chain wheel 3, turns and can be guided by the weight of the anchor chain 1 after coming out from the upper end. The limit box 5 is installed...

Embodiment 2

[0030] Take the 6500HP multi-purpose workboat undertaken by our company as an example, such as figure 1 As shown, the anchor chain 1 passes through the stern drum 13 and the shark jaw 14 at the stern of the ship to the hydraulic towing winch 2 at the midship position of the main deck through the wooden deck area, and guides the anchor chain 1 through the left and right anchor chain wheels 3 on the hydraulic towing winch 2 The chain pipes 4 on both sides of the chain enter the chain locker. When the chain pipes are full, the chain pipes 1 need to be guided to the wooden deck area and arranged sequentially. This is the anchor lifting operation process, otherwise it is the anchor dropping operation.

[0031] If the anchor chain 1 enters the chain from the upper end of the anchor chain wheel 3, under the influence of the height of the anchor chain wheel 3 and the weight of the anchor chain 1, there will be a large swing, which is difficult to control and is extremely unsafe. figu...

Abstract

The invention discloses a guide chain device, which relates to the field of guide chains of multipurpose work ships. A limiting seat, a limiting box and a guide chain groove are applied in a combined manner, and accordingly requirements of lifting and throwing of an anchor chain under working conditions of a long dragging distance and heavy weight can be met. The guide chain device is simple in structure, convenient in installation and suitable for guiding the anchor chain on a multipurpose work ship for a long distance, and anchor lifting and throwing operation can be effectively carried out when the guide chain device is cooperated with a power machine.

Description

technical field [0001] The invention relates to an anchor chain guiding device, in particular to a chain guiding device for a multipurpose workboat. Background technique [0002] The 6500HP multi-purpose workboat is an auxiliary vessel for marine engineering. A large hydraulic towing winch is installed at the midship of the main deck, and double drums are arranged at high and low levels. Among them, there is a chain pulley at both ends of the lower drum. , the suitable chain diameter of the left anchor chain wheel is 76mm anchor chain, the suitable chain diameter of the right anchor chain wheel is 84mm anchor chain. The winch is used for lifting and anchoring operations of various platforms and floating cranes such as drilling, oil production, and workover. See figure 1 , driven by the anchor chain wheel of the hydraulic towing winch, the anchor chain (of the above-mentioned offshore engineering facilities) goes from the stern of the ship to the main deck surface throu...
