Abstract
The invention relates to a safe and fast untwisting tow hook, which comprises a hooked substrate fixedly connected with a mothership, and also comprises a thumb web type supporting plate and a return spring, wherein the thumb web type supporting plate is movably connected with one side of the hooked substrate through a pin shaft, and the concave bottom radian and the concave slot radian of the hooked substrate are the same and are flush and overlapped; a guide pulley block and a limit pin are arranged on the hooked substrate, and a pull rope passing by the guide pulley block is connected onto the thumb web type supporting plate; the thumb web type supporting plate can counterclockwise rotate around the pin shaft by pulling the pull rope; the thumb web type supporting plate can clockwise rotate to return under the action of the return spring by loosening the pull rope, and is limited by the limit pin. According to the safe and fast untwisting tow hook provided by the invention, a cable can be untwisted easily and fast, so that the time and the labor are saved, the safety accidents such as man overboard or hull collision are thoroughly avoided, and the safety is high.
Description
Technical field
The present invention relates to a kind of hitcher buckling for hawser in operation that pulls, be specifically related to a kind of towing hook of being convenient to fast and safely untie the mooring rope.
Background technology
When towboat pulls operation, generally traction hawser is buckled and hung on the fixedly towing hook that is dragged lash ship, after having pulled, need towboat near lash ship, after lax hawser and by the towboat personnel operation of untying the mooring rope, time-consuming
Effort, especially, for the lash ship (as ground effect ship, hydroairplane or yacht etc.) with closed in spaces, also needs shipboard operation personnel deliver from vault to untie the mooring rope, and the safety misadventures such as man overboard or hull collision very easily occur under stormy waves environment.Therefore, need a kind of fast and safely actv. mode of operation that unties the mooring rope badly, this in case of emergency seems particularly important.
Summary of the invention
For existing, pull the defect that in operation, the traction hawser mode of untying the mooring rope exists, the applicant, through Improvement, provides a kind of towing hook that unties the mooring rope safely and fast.The present invention can realize quickly and easily moment in cabin and untie the mooring rope, time saving and energy saving, has thoroughly avoided the generation of the safety misadventures such as man overboard or hull collision, safe.
Technical scheme of the present invention is as follows:
The towing hook that unties the mooring rope safely and fast, comprises the hook-type pedestal affixed with lash ship, also comprises tiger's jaw type supporting plate and retracing spring; Tiger's jaw type supporting plate is movably connected on hook-type pedestal one side by bearing pin, and its concave bottom radian is identical and concordant overlapping with hook-type pedestal spill draw-in groove radian; Hook-type pedestal is provided with leading sheave group and locating dowel pin, is connected with the stay cord of pile warp leading sheave group on tiger's jaw type supporting plate; Pull stay cord, can realize tiger's jaw type supporting plate rotating counterclockwise around bearing pin; Lax stay cord, tiger's jaw type supporting plate clockwise rotates reset under action of reset spring, and spacing by locating dowel pin.
Its further technical scheme is:
Described hook-type pedestal spill draw-in groove and tiger's jaw type supporting plate concave bottom are used for carrying traction hawser.
Described retracing spring one termination is fixedly connected on hook-type pedestal, and another termination is fixedly connected on tiger's jaw type supporting plate
The described stay cord other end is connected to the stay cord handle of lash ship cabin interior.
The technique effect that the present invention is useful is:
The draw off gear that the present invention sets up a rotating tiger's jaw type supporting plate and consists of retracing spring, stay cord, leading sheave group on the basis of traditional fixed type towing hook pedestal, folding and unfolding action, the reset of retracing spring automatic tension by stay cord drive the suitable of tiger's jaw type supporting plate rotating counterclockwise, without towboat near lash ship, can easily realize rapidly moment in cabin unties the mooring rope, time saving and energy saving, thoroughly avoided the generation of the safety misadventures such as man overboard or hull collision; In addition, the indent of tiger's jaw type supporting plate design also can effectively prevent that traction hawser is from landing in hook-type pedestal draw-in groove, safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention (lax stay cord state).
Fig. 2 is structural representation of the present invention (pulling stay cord state, arrow A signal tiger's jaw type supporting plate rotation direction, arrow B signal stay cord direction).
Fig. 3 is hook-type base construction schematic diagram of the present invention.
Fig. 4 is tiger's jaw type support board structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is specifically described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention's towing hook that unties the mooring rope safely and fast comprises the hook-type pedestal 1 being fixedly connected with lash ship, also comprises tiger's jaw type supporting plate 5 and retracing spring 3; Tiger's jaw type supporting plate 5 is movably connected on hook-type pedestal 1 one sides by bearing pin 4, and its concave bottom radian is identical and concordant overlapping with hook-type pedestal 1 spill draw-in groove radian, for carrying traction hawser 8; Hook-type pedestal 1 is provided with leading sheave group 6 and locating dowel pin 2, is connected with the stay cord 7 of pile warp leading sheave group 6 on tiger's jaw type supporting plate 5, and stay cord 7 other ends are connected to the stay cord handle of lash ship cabin interior; Retracing spring 3 one terminations are fixedly connected on hook-type pedestal 1, and another termination is fixedly connected on tiger's jaw type supporting plate 5; Pull stay cord 7, can realize tiger's jaw type supporting plate 5 rotating counterclockwise around bearing pin 4; Lax stay cord 7, tiger's jaw type supporting plate 5 clockwise rotates reset under the effect of retracing spring 3, and spacing by locating dowel pin 2.
Specific works principle of the present invention is as follows:
As shown in Figure 1, while pulling operation, stay cord 7 is in relaxed state, tiger's jaw type supporting plate 5 is under retracing spring 3 tension force effects and locating dowel pin 2 position-limiting actions, fix with hook-type pedestal 1 relative position, now tiger's jaw type supporting plate 5 concave bottom are concordant overlapping with hook-type pedestal 1 spill draw-in groove, for carrying traction hawser 8, hook-type pedestal 1 bears the pulling force of traction hawser 8, and the simultaneously indent of tiger's jaw type supporting plate 5 design can prevent that traction hawser 8 is from landing in draw-in groove.
As shown in Figure 2, pull and finish to untie the mooring rope, lash ship underdeck operation personnel easily pull stay cord 7, and tiger's jaw type supporting plate 5 rotates counterclockwise around bearing pin 4, and traction hawser 8 is held up to hook-type pedestal 1 spill draw-in groove, and free pulling under power effect landing voluntarily.
Again unclamp stay cord 7, tiger's jaw type supporting plate 5 clockwise rotates reset under retracing spring 3 effects, restPoses, and now can carry out next round and pull operation.
The draw off gear that the present invention increases by a rotating tiger's jaw type supporting plate and consists of retracing spring, stay cord, leading sheave group on the basis of traditional fixed type towing hook pedestal, folding and unfolding action and retracing spring tension force by stay cord reset and can easily realize in cabin and untying the mooring rope rapidly, safe.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
