Description
Technical field
The utility model relates to a kind of cable cutter sweep, especially relates to a kind of rescue bell guide wire cable cutter sweep.
Background technology
Rescue bell is the preferred unit of world Navy submarine rescue system, also is one of state-of-the-art submarine rescue equipment of China naval.The mode of operation of rescue bell is: when submarine run under water emergency can not on when floating to the water surface, can be guide wire cable (wirerope) to be affixed on the lifesaving platform of submarine by the frogman, crane by lash ship hangs entry to rescue bell by the armouring cable then, on the safeguard station of rescue bell along the guide wire cable dive to submarine, and realization is docked with the effective of submarine, ship person enters in the rescue bell from submarine then, at last rescue task is finished in rescue bell lifting water outlet one time.In whole rescue process, guide wire cable is by the release of the hydraulic wireline winch in the rescue bell hold and reclaims, if during the case of emergency that guide wire cable can not effectively discharge, need carry out emergency switching-off to guide wire cable, guarantee that rescue bell can get back to the water surface safely with cutter sweep.At present, conventional guide wire cable cutter sweep is scissor, when needs cut off guide wire cable, this cutter sweep needs rescue bell to be furnished with manipulator, grasp cutter with manipulator wirerope is snapped into enforcement cut-out on the edge of a knife, this class cutter sweep complex structure, operation and maintenance be difficulty, can't implement Long-distance Control cutting guide wire cable, and the manufacturing cost height.
The utility model content
The applicant has carried out research and improved at above-mentioned problem, and a kind of rescue bell guide wire cable cutter sweep is provided, and is simple in structure, operation and easy to maintenance, remote controlled cutting guide wire cable, and low cost of manufacture.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of rescue bell guide wire cable cutter sweep, comprise cutting part and drive oil cylinder, described cutting part comprises sleeve, decide cutter and be fixedly mounted on the interior front end of sleeve, moving cutter slide over the rear end in the sleeve, the rear portion of moving cutter connects the piston rod that drives oil cylinder, deciding the shear surface of cutter and the shear surface of moving cutter is slidingly matched, decide to be respectively equipped with shearing perforation on cutter and the moving cutter, sleeve is provided with the guide wire cable hole, when original state, decide the shearing perforation of cutter, the shearing perforation of moving cutter and the guide wire cable hole on the sleeve overlap, and guide wire cable passes the shearing perforation of deciding cutter, the shearing perforation of moving cutter and the guide wire cable hole on the sleeve.
Further:
The diameter in described guide wire cable hole is less than the diameter of the diameter of deciding the cutter shearing perforation and moving cutter shearing perforation.
Technique effect of the present utility model is:
The disclosed a kind of rescue bell guide wire cable cutter sweep of the utility model, simple in structure, operation and easy to maintenance, low cost of manufacture; Drive oil cylinder connection cutting part and guide wire cable and pass cutting part, in case of emergency, remote controlled cut-out guide wire cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A place cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As Fig. 1, shown in 2, the utility model comprises cutting part 200 and drives oil cylinder 100, cutting part 200 comprises sleeve 1, decide cutter 4 and be fixedly mounted on front end in the sleeve 1 by bearing pin 5, moving cutter 2 slide over the rear end in the sleeve 1, the rear portion of moving cutter 2 connects the piston rod 8 that drives oil cylinder 100 by bearing pin 6, deciding the shear surface 402 of cutter 4 and the shear surface 202 of moving cutter 2 is slidingly matched, decide cutter 4 and be provided with shearing perforation 401, moving cutter 2 are provided with shearing perforation 201, sleeve 1 is provided with guide wire cable hole 101, when original state, decide the shearing perforation 401 of cutter 4, the shearing perforation 201 of moving cutter 2 and the guide wire cable hole on the sleeve 1 101 overlap, and guide wire cable 3 passes the shearing perforation 401 of deciding cutter 4, the shearing perforation 201 of moving cutter 2 and the guide wire cable hole 101 on the sleeve 1.The diameter in guide wire cable hole 101 is less than the diameter of the diameter of deciding cutter shearing perforation 401 and moving cutter shearing perforation 201, can guarantee that like this guide wire cable 3 can not decided cutter 4 or 2 scratches of moving cutter.
In use, drive the side that oil cylinder 100 is installed in the moving cutter 2 of sleeve 1, and driving oil cylinder 100 is fixedly mounted on the installing plate 7 by screw-nut 9 with sleeve 1.Under normal circumstances, guide wire cable 3 passes the shearing perforation 401 of deciding cutter 4, the shearing perforation 201 of moving cutter 2 and the guide wire cable hole 101 on the sleeve 1, and guide wire cable 3 can free folding and unfolding, and guide wire cable 3 is in state to be cut all the time; When running into emergency rating, normally during folding and unfolding, the remote controlled piston rod 8 that drives oil cylinder 100 that makes stretches out guide wire cable 3, makes cutter 2 decide cutter 4 slips relatively, can cut off guide wire cable 3 at once.
