Detailed description of the invention
It is embodied as below in conjunction with the accompanying drawings this utility model is described in further detail.
Seeing Fig. 1, steel wire end fixing device is by connecting ear plate 1, oscillating bearing 2, and it is former that bearing pin 3(presses uniform strength design, this
Other pin diameter of device is identical), drawplate type force cell 4, safeguard 5, wire rope wedge form joint 6 form.
Drawplate type force cell 4, safeguard 5 are assembled together by bearing pin 3, and drawplate type force cell 4 is provided with
For the upper and lower force cell pin shaft hole 401 assembled with bearing pin 3, sensor be placed in the middle of drawplate type force cell 4
In gauge hole 402；Safeguard 5 is provided with the upper and lower safeguard pin shaft hole 501 for assembling with bearing pin 3；
Wherein an aperture in safeguard pin shaft hole 501 is more than the aperture of force cell pin shaft hole 401, preferably 5mm,
So safeguard 5 does not stresses in the course of the work.Connecting ear plate 1 and oscillating bearing 2 are passed through in drawplate type force cell 4 top
Being connected in frame, bottom is by bearing pin 3 and wire rope wedge form joint 6, and wire rope wedge form joint 6 couples steel wire rope.
As shown in Figure 1, Figure 2, Figure 3 shows, the one comprehensive steel wire end fixing device designed by this utility model.
When being embodied as, connecting ear plate 1 and frame are connected, otic placode built with oscillating bearing 2, oscillating bearing 2 can basis
Anglec of rotation selection standard type oscillating bearing or our company's Design and Machining in steel wire rope work process close bearing, i.e. steel wire rope work
With regard to selection standard oscillating bearing during the anglec of rotation that the anglec of rotation during work allows less than standard oscillating bearing, if steel wire
During the anglec of rotation that the anglec of rotation in rope work process allows less than standard oscillating bearing, the another Design and Machining of our company makes closes
Bearings meets the anglec of rotation requirement in steel wire rope work process；Drawplate type force cell 4, safeguard 5 are through upper and lower survey
Force transducer pin shaft hole 401 and safeguard pin shaft hole 501 are assembled together, as load limiter effect, arm-tie by bearing pin 3
Formula force cell 4 is to be stressed directly part, without any loss of tension, can directly reflect pulling force size, and safeguard 5 has 2, if
Counting a boring ratio drawplate type force cell 4 big 5mm of centre-to-centre spacing in 5 liang of pin-and-holes of plate of insuring, drawplate type force cell 4 is installed in
In the middle of 2 pieces of safeguards 5, when rupturing such as drawplate type force cell 4, safeguard 5 shields, and is not resulted in fixing end and breaks thing
Therefore.Drawplate type force cell 4, the structural type of safeguard 5 are the key technologies of this steel wire end fixing device；Steel wire rope wedge shape
Joint 6 belongs to standard component, selects by steel wire rope specification.
Above institute art this utility model is the preferred embodiments that steel wire end is fixing, it should be pointed out that this utility model steel wire
End fixing device adapts to the lifting mechanism for the high-lift goliath of large-tonnage and jib lubbing mechanism very much, without departing from this
