Can test method, with reference to attached drawing 1, device specifically include hoist engine 1, load rope 2, sensor 5, positioning device 3 and with positioning
Device connection fixed pulley 4, in use, load rope 2 one end connect hoist engine 1, the other end around fixed pulley 4 via with sensing
Device 5 connects, and is finally connect with the top end of composite material electric pole.With the test data of 15 meters of concurrents and composite material electric pole
Comparison, the amount of deflection at corresponding tip diameter end respectively may be about 1250mm and 4000mm when failing load acts on, it is seen that composite material electric pole
Electric pole bending is obvious under peak load effect.But since the fixed pulley position for turning to load rope is positioned and fixed, with
Further drawing of the hoist engine to load rope, electric pole is bent to fixed pulley direction, and the top end of electric pole is gradually inclined in bending process
From the bit line 6 where former top end, therefore loads rope and also changed correspondingly in the direction of top end side, the bit line where electric pole original top end
The 6 angle a to restrict with load(Load rope angle changing)It changes greatly so that Load Simulation is inaccurate.In addition top end lanyard point with
Electric pole is bent after curve movement, and load rope becomes larger with shaft angle, and as electric pole bending is increasing, load rope is easily from top end
Lanyard point is fallen off.
Invention content
The purpose of this utility model is that according to prior art shortcoming and provide one kind can reduce load rope side
To variation, the composite material electric pole mechanical property test device for improving Load Simulation accuracy, load rope being avoided to fall off.
Composite material electric pole mechanical property test device described in the utility model is realized by following approach:
A kind of composite material electric pole mechanical property test device includes that hoist engine, load rope and sensor, structure are wanted
Point is, further includes that have two-way movable pulley, turn to fixed rope and two places anchored site, two-way movable pulley include track movable pulley
With load movable pulley, two movable pulleys are fixed by the bracket connection, and the outside that two places anchored site is separately mounted to electric pole top end is empty
Between and lower section, the both ends for turning to fixed rope be separately connected two places anchored site, centre string is around track movable pulley;Load one end of rope
Hoist engine is connected, other end string connects sensor after load movable pulley, and is finally fixedly connected with electric pole top end.
The test method of above-mentioned experimental rig, includes the following steps:
1)A kind of experimental rig as described above is provided, electric pole is fixed using fixture, is fixed on testing bed, testing stand, electric pole
Pad coaster in middle part;Hoist engine is arranged in electric pole fixed point direction,
2)Load movable pulley of the load rope in two-way movable pulley on hoist engine, and connect with sensor, then connect
It is connected on the lanyard point of electric pole top end,
3)Start hoist engine, draw and tighten load rope preloaded, at this time electric pole top end be original state, do not added
The tractive force of rope is carried,
4)Under preload condition, the position of adjustment load movable pulley and track movable pulley so that connection hoist engine side
Load rope be parallel to the electric pole body of rod, and connect electric pole top end the other side load rope perpendicular to the electric pole body of rod;
5)The position of adjustment load movable pulley and track movable pulley, observes whether two-way movable pulley can smoothly slide,
If cannot smoothly slide, needs to carry out pulley surface processing or replace pulley;
6)Start hoist engine, traction load is restricted, and electric pole top end is moved gradually downward, to testing bed, testing stand direction so that electricity at this time
Bar generate bending, and two-way movable pulley by respectively load rope and turn to fixed rope on sliding by with electric pole top end to
Testing bed, testing stand direction is moved,
7)After electric pole reaches the amount of deflection of setting, stop hoist engine, log.
Due to two-way movable pulley by respectively load rope and turn to fixed rope on sliding by with electric pole top end to
Testing bed, testing stand direction is moved, therefore the load rope for connecting electric pole top end side is almost translational movement, therefore loads the change of rope
It is extremely small to change angle, by taking 15 nano composite material electric poles as an example, electric pole top end routine test device and the utility model experiment
Device is tested respectively, it is assumed that when amount of deflection all reaches 1500mm, is measured using routine test device and the utility model experimental rig
Load rope angle changing is respectively 20 degree and 3 degree, it is seen that it is bright that the utility model experimental rig reduces load rope direction change angle
It is aobvious.The utility model solves the examination of electric pole mechanical property by the direction of the self-regulating function adjustment load rope of movable pulley as a result,
The problem that loading rope direction change is big in loading procedure is tested, ensures that the simulation of electric pole finder charge is more acurrate;In addition, since load is restricted
Angle changing it is small, almost keep it is vertical with electric pole therefore less easy to fall off, it is ensured that the reliable and stable progress of experiment.
The utility model can be specially further:
Line between the anchored site of two places and angle is 45 degree between the load rope direction of electric pole, two-way dynamic
In pulley moving process, deviation is ± 20 degree.
In order to obtain very fast and more accurately adjust, the company between the anchored site of two places in actual mechanical process
Line is with vertical load rope clamp angle preferably at 45 degree.And it further limits its distance and is:
The distance between described two places anchored site is 3-5m.
In conclusion the utility model provides a kind of composite material electric pole mechanical property test device, using slidably
Two-way movable pulley according at composite material electric pole top end variation voluntarily adjustment load steel wire rope turning point position, to subtract
The angle of load rope direction change, solves electric pole top end loading rope and is asked with what top end direction of displacement changed in small loading procedure
Topic, so that electric pole top end is loaded, rope direction remains constant or direction change is little, ensures that the simulation of electric pole finder charge is more acurrate,
In addition, since the angle changing of load rope is small, almost keep vertical with electric pole therefore less easy to fall off, it is ensured that the stabilization of experiment
It is reliable to carry out.
