Described holder becomes box-like.
Between described V-type face frame, form 14 ° of angles of wedge.
Described pincers tooth fixture is 2, clamps and between tooth fixture and holder, form 14 ° of angles of wedge described in two.
Described feather key is 2.
Compared with prior art, the present invention has following beneficial effect:
Low cost of manufacture, due to the application of inclined wedge augmenting mechanism, needs very little boosting oil cylinder just can meet the demands.
The application of synchronous device, guarantees to clamp tooth stressed evenly to wire rope.
Pincers tooth is v block structure alternating between negative and positive, makes its wire rope specification trial stretch have versatility.

Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Fig. 1-8, hydraulic separating clamp, comprise holder 1, bearing pin 2, arm-tie 3, pincers tooth 4, feather key 5, keyway plate 6, oil cylinder 9, extending seat 10, web joint 11, curb girder 12, sliding seat 13, between holder 1 and extending seat 10, be connected by two curb girders 12,1 one-tenth of holder is box-like, and holder 1 inside is connected with sliding seat 13, hole is opened on holder 13 tops, two feather keys 5 are anchored on sliding seat 13, and feather key 5, in the interior slip of keyway plate 6, ensures that pincers tooth synchronous clamping unclamps.In holder 1 top circular hole, insert the fixing arm-tie 3 of bearing pin 2, holder 1 is formed to a sealing primary structure member.Holder 1 inside is provided with V-type face frame, and frame both sides are all provided with lubricating system, and V-type face frame angle is 14 °.In the V-type face frame of holder 1, there is the pincers tooth fixture of relative sliding, pincers tooth fixture is 2 pincers teeth secondary alternating between negative and positive, two pincers tooth fixtures form 14 ° of angles of wedge, pincers tooth fixture connects together by web joint 11 and sliding seat 13 for clamping tooth 4, pincers tooth 4 adopts quenching type alloy steel material to make, and pincers tooth fixture and holder V-type face frame form two slip mill sassafras pairs.Between sliding seat 13 and extending seat 10, be also connected with two oil cylinders 9, the head and the tail two ends of oil cylinder 9 are fixed with an oil cylinder seat 7 with wearing pin 8 respectively, oil cylinder 9 head ends are connected in sliding seat 13 by oil cylinder seat 7, oil cylinder 9 tail ends are connected in extending seat 10 by oil cylinder seat 7, and the layout angle of oil cylinder 9 is consistent with the layout angle of pincers tooth fixture.
Hydraulic separating clamp oil cylinder 9 needs independent hydraulic system that hydraulic energy is provided.Start Hydraulic Station, by release button, two oil cylinder 9 pistons are return, pincers tooth 4 is in open mode.Take off keyway plate 6, pull out a side bearing pin 2 and remove arm-tie 3 tested rope rig one end is connected with main frame, rigging rope body adjust suitable after, another section of rope body divides puts into pincers tooth 4.Retract arm-tie 3, insert bearing pin 2, load key frid 6.
By clamping button, oil cylinder 9 piston rods stretch out, pincers tooth 4 synchronous clamping wire rope.Because two secondary pincers teeth 4 are v block structure alternating between negative and positive, it is stressed evenly that wire rope clamps position.Protect and carry certain hour, main frame pulling force is cancelled and rollback.Press release button, pincers tooth 4 rollbacks also unclamp wire rope.Take off keyway plate 6, pull out a side bearing pin 2, remove arm-tie 3, take out wire rope.For working cycle is next time prepared.
Principle explanation: hydraulic separating clamp, according to inclined wedge augmenting mechanism principle, changes oil cylinder 9 thrusts into clamping force.Change the normal pressure of pincers tooth 4 to wire rope into.In the time applying main pulling force, between pincers tooth 4 and wire rope, grind sassafras coefficient and increase, grind sassafras power and increase.So main pulling force increases.The key of hydraulic separating clamp is that solve should reinforcement, again can not self-locking.Pincers tooth material is quenching type alloy steel, and its hardness ratio wire rope steel wire hardness is low, possesses rational life-span and good friction factor.As calculated, under sufficient lubrication condition, 5.8 ° of self-lockings of the secondary angle of wedge of kinetic friction.Verification experimental verification: under certain main pulling force load, 7 ° of the angles of wedge, wire rope and pincers tooth 4 are without relative sliding, not self-locking.Meet the pulling test of tension tester between drawing a little to rigging.
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any amendment of doing, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
