Description
Technical field
The present invention relates to the Current Collector Sleave apparatus field, particularly relate to tensile test equipment.
Background technology
The prosperity of Current Collector Sleave industry brings rare opportunity for the development of tensile test equipment industry.Domestic and international rigging processing factory, harbour, bridge, venue working-yard, tension tester is all used in every linear rigging application scenario.The tensile test function is accomplished data computing such as static load, extensibility automatically.Puller system length is certain, but rigging or wire rod length specific thrust captain require test between rigging draws a little, verify rigging intensity.Clamp to rigging, all adopt hydraulic cylinder vertical positive technology both at home and abroad.Hydraulic cylinder is exported much power, and normal pressure is much, increase power, promptly increases hydraulic cylinder or system pressure, and limitation is very big.Be to adapt to present situation, can change original hydraulic pressure the principle of clamping into, design a kind of hydraulic pressure elastic separating plier that possesses the stretch-draw function, the test between the completion rigging draws a little according to inclined wedge augmenting mechanism.Satisfy the pulling test of tension tester between drawing a little to rigging.
Summary of the invention
The invention reside in the defective that has overcome prior art, a kind of hydraulic pressure elastic separating plier is provided, it is strong to have applicability, high reliability features.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Comprise holder, arm-tie, pincers tooth, feather key, keyway plate, oil cylinder, extending seat, web joint, curb girder, sliding seat; Said holder is connected through curb girder with extending seat, and said holder inside is connected with sliding seat, and the hole is opened on said holder top; Said feather key is anchored in the sliding seat; Said feather key slides in the keyway plate, and lubricating system is all installed in the inner V-type face of said holder frame both sides, and said pincers tooth anchor clamps connect together through web joint and sliding seat for the pincers tooth; Slide relatively between said pincers tooth anchor clamps and the holder V-type face; Said oil cylinder is connected with sliding seat, extending seat respectively through the fixing oil cylinder seat in head and the tail two ends, and the layout angle of said oil cylinder is consistent with the layout angle of pincers tooth anchor clamps, and said holder top is fixed with arm-tie.
Said holder becomes box-like.
Constitute 14 ° of angles of wedge between the said V-type face frame.
Said pincers tooth anchor clamps are 2, constitute 14 ° of angles of wedge between two said pincers tooth anchor clamps and the holder.
Said feather key is 2.
Compared with prior art, the present invention has following beneficial effect:
Low cost of manufacture is because the application of inclined wedge augmenting mechanism needs very little boosting oil cylinder just can meet the demands.
The application of synchronous device, it is stressed evenly to wire rope to guarantee to clamp tooth.
The pincers tooth is a 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 is used for explanation and explains the present invention, and be not used in qualification the present invention.
Shown in Fig. 1-8, the hydraulic pressure elastic separating plier comprises 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; Be connected through two curb girders 12 between holder 1 and the extending seat 10,1 one-tenth of holder is box-like, and holder 1 inside is connected with sliding seat 13; The hole is opened on holder 13 tops; Two feather keys 5 are anchored on sliding seat 13, and feather key 5 slides in keyway plate 6, guarantee the synchronous clamping and release of pincers tooth.Insert fixedly arm-tie 3 of bearing pin 2 in the holder 1 top circular hole, holder 1 is formed a sealing primary structure member.Holder 1 inside is equipped with V-type face frame, and the frame both sides all are equipped with lubricating system, and V-type face frame angle is 14 °.The pincers tooth anchor clamps that relative slip is arranged in the V-type face frame of holder 1; Pincers tooth anchor clamps are 2 pairs pincers teeth alternating between negative and positive; Two pincers tooth anchor clamps constitute 14 ° of angles of wedge; Pincers tooth anchor clamps connect together through web joint 11 and sliding seat 13 for pincers tooth 4, and pincers tooth 4 adopts quenching type alloy steel material to process, and it is secondary that pincers tooth anchor clamps and holder V-type face frame constitute two slip mill sassafras.Also be connected with two oil cylinders 9 between sliding seat 13 and the extending seat 10; 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 through oil cylinder seat 7; Oil cylinder 9 tail ends are connected in extending seat 10 through oil cylinder seat 7, and the layout angle of oil cylinder 9 is consistent with the layout angle of pincers tooth anchor clamps.
Hydraulic pressure elastic separating plier oil cylinder 9 needs independent hydraulic system that the hydraulic pressure ability is provided.Start Hydraulic Station, press release button, two oil cylinders, 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 linked to each other with main frame, after the adjustment of rigging rope body was suitable, another section rope body portion was put 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, and pincers tooth 4 clamps wire rope synchronously.Because two secondary pincers teeth 4 are v block structure alternating between negative and positive, it is stressed evenly that wire rope clamps the position.Protect and carry certain hour, the 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.
The principle explanation: the hydraulic pressure elastic separating plier changes oil cylinder 9 thrusts into clamping force according to the inclined wedge augmenting mechanism principle.Promptly change the normal pressure of 4 pairs of wire rope of pincers tooth into.When applying main pulling force, mill sassafras coefficient increases between pincers tooth 4 and wire rope, promptly grinds sassafras power and increases.So main pulling force increases.The key of hydraulic pressure elastic separating plier is that solve should reinforcement, again can not self-locking.The pincers tooth material is a quenching type alloy steel, and its hardness ratio wire rope steel wire hardness is low, possesses rational life-span and good friction factor.Through calculating, under the 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 slides not self-locking relatively with pincers tooth 4 nothings.Satisfy the pulling test of tension tester between drawing a little to rigging.
The above is merely explanation embodiment of the present invention; Be not limited to the present invention, for a person skilled in the art, all within spirit of the present invention and principle; Any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
