There is no voussoir to be fixed, thus it is a large amount of that needs when two steel cable fag ends are fixed are stuck in using common steel cable rope
Time and manpower rope clamping can be consolidated, and the movable hydraulic cylinder test of needs, until steel cable fasten it is motionless
Untill, not only waste time and energy, labor intensity is big, and operating efficiency is low, unit operation rate is influenceed, while also depositing
In greatly potential safety hazard.
The content of the invention
It is contemplated that the locking connection of the quick large-scale steel cable fag end for realizing tensile force of belt, reduces labor intensity,
Raising personnel and unit operation rate, it is to avoid security incident.
Therefore, the technical solution that the present invention is taken is：
A kind of tensile force of belt steel cable fag end locking and connecting device, by pressuring pump, hydraulic cylinder, pressure nut, regulation
Bolt, guide pad, guide rod, jam nut, upper latch segment, lower latch segment and pre-load nut composition；Beat
Press pump is connected with hydraulic cylinder, and hydraulic cylinder both sides are respectively equipped with the guide pad of a middle with hole, and two guide pads lead to
Cross two regulating bolt lateral connections together, hydraulic cylinder cylinder rod lower end is connected under upper latch segment, upper latch segment
Face is provided with lower latch segment, and upper latch segment is corresponding with the middle of lower latch segment to be provided with " u "-shaped neck, and both sides are provided with and led
Rod aperture, guide pad, upper latch segment, lower latch segment are serially connected by guide rod, and guide rod upper end is carried
Pressure nut, lower end is carried to be installed on pre-load nut, the guide rod between guide pad and upper latch segment
Full nut.
Ripple is machined with the card groove sidewall of the upper latch segment and lower latch segment.
Tensile force of belt steel cable fag end of the present invention locks the specific method connected：
(1) two steel cable fag ends for being intended to connection are inserted in the neck of latch segment and lower latch segment respectively.
(2) lower latch segment is made to increase by the pre-load nut of rotary steering bar lower end, until by two steel cable ropes
Head is pressed against in the neck of latch segment and lower latch segment, fixes the position of two steel cable fag ends.
(3) hydraulic cylinder is suppressed using pressuring pump, hydraulic cylinder cylinder rod drives connected upper latch segment
Move down, so as to two steel cable fag ends are pressed in the neck of upper latch segment and lower latch segment.
(4) two jam nuts being directed on bar are locked onto upper latch segment, that is, complete two steel cables
The locking connection of fag end.
Beneficial effects of the present invention are：
Fag end locking and connecting device of the present invention is simple in construction, invests small, is easy to operation, and function-stable is reliable,
It can be iteratively repeated and use, and the steel cable needs of different-diameter can be adapted to by replacing with lower latch segment, be applicable
Scope is wide, only needs a people quickly to carry out the locking connection of the large-scale steel cable fag end of tensile force of belt, so as to save
Labour is saved, is greatly reduced labor intensity, shortens the steel rope lock tight Connection Time, personnel's operating efficiency and machine is improved
Group production capacity, and personal injury accident is prevented effectively from, reduce causality loss.
