Description
Technical field
This utility model belongs to field of measuring technique, particularly relates to a kind of measurement angle member torsional resistance apparatus.
Background technology
The high voltage transmission line tower of steel angle structure is the most universal at present, diagonal angle steel matter includes mechanical performance and chemical composition, it is all to the every batch of steel test dispatched from the factory, the mechanical performance sample doing standard pattern size carries out the test such as mechanical stretching and bending, provide the mechanical properties data of every batch of material, material of i.e. dispatching from the factory list.Occurring for the situation of falling tower, it is contemplated that the angle member of exact shape should be carried out twisting resistance performance test, comparing the angle member just dispatched from the factory, the angle member being on active service for many years, the data measured can preferably analyze high voltage transmission line tower steel performance.For angle member, overall dimensions, including wall thickness and geomery, directly affect the mechanical property of angle member.Sometimes due in using for many years, the corrosion of steel also can make overall dimensions occur thinning to wait change, and the rigidity of steel and the performance such as tired also can change.
Utility model content
In place of above-mentioned the deficiencies in the prior art, this utility model provides one to measure angle member torsional resistance apparatus.Its object is to can be more accurately to high voltage transmission line tower angle member actual measurement twisting resistance.
In order to realize above-mentioned utility model purpose, this utility model is achieved through the following technical solutions:
A kind of measurement angle member torsional resistance apparatus, is connecting test angle steel on firm banking, and the other end of tested angle steel connects moment of torsion chuck；The base bracing frame top of the base other end connects travel mechanism, and one end of the torque tube in travel mechanism is connected with moment of torsion chuck.
Described travel mechanism includes: torque tube is sleeved in sliding sleeve, and down-feed screw is arranged on base bracing frame, and one end of down-feed screw connects leading screw handwheel, and rotational lead screw handwheel drives slide and pinch roller to move along a straight line；Sliding sleeve side is provided with pinch roller, and pinch roller is connected on slide.
The other end of described torque tube is provided with mobile pointer.
On described base bracing frame, upper connection has scale.
Described moment of torsion chuck is provided with Digital-display torque.
Described base is calipers base or angle steel base.
Described firm banking is provided with handwheel, is fixedly connected on base by tested angle steel by handwheel.
This utility model hinge structure has the advantage that and beneficial effect:
This utility model can be to high voltage transmission line tower angle member i.e. product piece actual measurement twisting resistance, the angle steel that newly dispatches from the factory for the various material of same style number, use neutralize use after the angle steel changed in different years, the angle steel of sampling after tower that falls carry out the measurement of twisting resistance, effective data are provided, it is also possible to effective raising work efficiency and the precision of measurement for high voltage transmission line tower normal service.
Below in conjunction with the accompanying drawings and specific embodiment, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the top view of Fig. 1.
In figure: base 1, handwheel 2, test angle steel 3, moment of torsion chuck 4, torque tube 5, sliding sleeve 6, pinch roller 7, leading screw handwheel 8, mobile pointer 9, leading screw 10, Digital-display torque 11, scale 12；Base bracing frame 13；Slide 14.
Detailed description of the invention
As it is shown in figure 1, this utility model is a kind of measurement angle member torsional resistance apparatus, being to be fixed on base 1 by tested angle steel 3 by handwheel 2 on firm banking 1, the other end of tested angle steel 3 connects moment of torsion chuck 4, and moment of torsion chuck 4 is provided with Digital-display torque 11.Described base 1 is calipers base or angle steel base.
Base support 13 top of base 1 other end connects travel mechanism, this travel mechanism is: torque tube 5 is sleeved in sliding sleeve 6, down-feed screw 10 is connected on base bracing frame 13, and one end of down-feed screw 10 connects leading screw handwheel 8, and leading screw drives slide 14 to move along a straight line.Pinch roller 7 is fixed on slide 14.One end of torque tube 5 connects moment of torsion chuck 4, and the other end of torque tube 5 is provided with mobile pointer 9, and scale 12 is fixed on base bracing frame 13.
During enforcement, being first fixed on base 1 one end of the tested i.e. standard component of angle steel 3, and clamp with handwheel 2, angle steel 3 other end loads onto moment of torsion chuck 4, when testing angle steel 3 and being lax, is close to pinch roller 7.Start to do twisting resistance to measure, shake leading screw handwheel 8, slide 14 is made to move along a straight line, and drive pinch roller 7, torque tube 5 is being acted on pinch roller 7 by horizontal power, torque tube 5 is when by cross force, and torque tube 5 and pinch roller 7 will be in 14 times movements of drive slide of down-feed screw 10, and sliding sleeve 6 solves the travel mechanism of down-feed screw 10 exactly.Reading on mobile pointer 9, displacement more than 1,2 millimeters, read the torsion numerical value on Digital-display torque 11 simultaneously, such as mobile 1 millimeter, torsion numerical value is how many kilogram-metres.So new angle steel to sampling observation, the old angle steel for many years of being on active service, new, the angle steel for many years of being on active service that different manufacturers produces, the differentiated angle steel of wall thickness, carry out torque data and compare, according to measurement data, analyze the twisting resistance of the angle member of various state.
During enforcement, selected base 1 can be calipers base, it is also possible to for angle steel base, all within enforcement protection domain of the present utility model.
