Description
Technical field
The utility model, in particular to a kind of quick-release type towing force hoisting pad, belongs to ship ' s equipment technical field.
Background technology
Towing force hoisting pad is the important component part of marine towage system.Towage also claims traction, refers to that another ship or other floatability object are dragged to another ground from a ground by a ship.Marine towage system can be applicable to the marine traction of the dumb craft oceangoing ships such as FPSO, salvor, pipe laying crane ship, dredger, platform.Above deck, before traction, the end link of friction chain is connected on the bearing pin of towing force hoisting pad in towing force hoisting pad welding, and it is axial and circumferential mobile to take measures to prevent bearing pin from occurring.In Towing System, the design of towing force hoisting pad adopts the Nippon Standard of 1979 so far: on bearing pin, weld thrust baffle, prevent bearing pin from producing moving axially of a direction, penetrate retaining bearing pin, prevent bearing pin from producing moving axially of other direction, the below welding round steel of bearing pin, is absorbed in the groove of auxiliary riser, prevents bearing pin from producing circumference and rotates.When friction chain is freed, thrust baffle need be knocked out with instrument, polish weld seam.The major defect of this structure is: thrust baffle adopts welding manner, needs to remove weld seam before dismounting bearing pin; On bearing pin, perforate affects bearing pin intensity; The chain link of retaining bearing pin needs anchor fitting.Along with the development of ocean engineering, marine towing operation is very frequent, up to designing a kind of towing force hoisting pad form that can install rapidly and free.
Utility model content
In order to solve exist in prior art towage friction chain can not connect fast with free for inscribe, the utility model proposes a kind of quick-release type towing force hoisting pad.
The technical solution of the utility model is such realization: a kind of quick-release type towing force hoisting pad, comprise base plate, eye plate, towing chain and bearing pin, described bearing pin is provided with a groove vertically, described bearing pin one end is connected with handle, described handle is provided with a latch, described latch is symmetrically distributed in described handle both sides, and be connected with described handle by rotating shaft, described latch can rotate around the shaft, described latch side is by extension spring and described pinned connection, retaining floor is provided with below described bearing pin, described retaining floor is just provided with groove to the position of bearing pin, when described bearing pin is in free state, described groove is just to the groove of described retaining floor, handle is horizontal, 90 °, clickwise handle, the groove of bearing pin is horizontal, and the flange of bearing pin snaps in the axial location realizing bearing pin in the groove of retaining floor, latch rotates clockwise 90 °, is positioned at the retaining floor left and right sides, and the upper end of described retaining floor, in vertical direction higher than the lower end of described latch, realizes the circumference location of bearing pin.
Preferably, described latch is provided with clamp handle, for rotating described latch.
Preferably, described handle is by handle gusset piece and described pinned connection.
Preferably, described extension spring one end is by extension spring permanent seat and described pinned connection, and the other end is connected with described latch by extension spring hanging scroll.
The beneficial effects of the utility model: quick-release type towing force hoisting pad of the present utility model, structure is simple, manually can complete axial, the circumference location of bearing pin, easy to operate, quick.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model quick-release type towing force hoisting pad;
Fig. 2 is the lateral plan of Fig. 1;
In figure: 1 base plate, 2 eye plates, 3 grooves, 4 bearing pins, 5 handles, 6 handle gusset pieces, 7 rotating shafts, 8 latchs, 9 latch handles, 10 retaining floors, 11 extension spring hanging scrolls, 12 extension springs, 13 extension spring permanent seats, 14 grooves.
Detailed description of the invention
By reference to the accompanying drawings the embodiment that the utility model provides is described in further detail:
As Fig. 1, shown in 2, a kind of quick-release type towing force hoisting pad, comprise base plate 1, eye plate 2, towing chain and bearing pin 4, described eye plate 2 is two, two eye plates 2 are installed in parallel on base plate 1, bearing pin 4 inserts in eye plate 2 hole, towing chain is connected on bearing pin 4, described bearing pin 4 is provided with a groove 3 vertically, described bearing pin 4 one end is connected with handle 5, described handle 5 is provided with a latch 8, described latch 8 is symmetrically distributed in described handle 5 both sides, and be connected with described handle 5 by rotating shaft 7, rotating shaft 7 one end is welded on the latch of left side, the other end is connected on the latch of right side through the eyelet welding on handle gusset piece 6, form the rotating shaft of latch 8, extension spring hanging scroll 11, latch handle 9 is welded on both sides latch 8 respectively, extension spring permanent seat 13 is welded on the end face of bearing pin 4, extension spring 12 one end connects extension spring permanent seat 13, the other end connects hanging scroll 11, be provided with retaining floor 10 below described bearing pin 4, described retaining floor 10 is just provided with groove 14 to the position of bearing pin 4.
When described bearing pin 4 is in free state, described groove 3 is just to the groove 14 of described retaining floor 10, and handle 5 is horizontal; 90 °, clickwise handle, the groove 3 on bearing pin 4 is horizontal, and the flange of bearing pin 4 snaps in the axial location realizing bearing pin 4 in the groove of retaining floor 10; Latch 8 rotates clockwise 90 °, is positioned at retaining floor 10 left and right sides, and the upper end of described retaining floor 10, in vertical direction higher than the lower end of described latch 8, realizes the circumference location of bearing pin 4.
When friction chain is freed, rotate counterclockwise latch 8, make it depart from retaining floor 10, rotate counterclockwise handle 5, the square groove on bearing pin 4 flange is in position vertically downward, can exit bearing pin 4, releasable friction chain.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
