Abstract
The utility model relates to a multifunctional tensile force tester, particularly a tester which is used for testing the strength safety of power line appliances and hardware. The utility model is composed of a machine frame, a dynamometer and a pull rod. A horizontal top frame is arranged on the top of the machine frame. The utility model is used for testing the bending resistance of rod members, and meanwhile the utility model can test the torque force, the oblique supporting force and the pole climbers of the rod members and the tensile safety strength of the safety belt.
Description
The utility model relates to a kind of multifunctional pull proving installation, is the proving installation of power with the manpower particularly, is particularly suitable for the security intensity or the stretching resistance test of power circuit Work tool, gold utensil.
The existing test unit that is used for the test material mechanical property, be suitable for mostly using under the laboratory condition, a kind of " multifunctional material testing machine " disclosed as Chinese patent CN2079293U, this eedle is transformed the load maintainer of existing universal testing machine, the nut tube is changed into the employing clasp nut, becoming screw mandrel moves axially to rotating, becoming nut rotates to moving axially, changing force measuring machine into comprehensive dynamometer, is the multifunctional material testing machine of a machine thereby constitute collection stretching, a compression, bending, shearing, twisting test.
This testing machine is applicable to that the laboratory does material mechanical performance test, and can not be used to do the Work tool test, especially large-scale Work tool is not suitable for.
In order to adapt to job safety needs such as power circuitry engineering construction, maintenance, our unit once succeeded in developing a kind of simple and easy tension tester, this machine is made up of frame, dynamometer, pull bar, is mainly used in to measure small-sized Work tool, as the stretching resistance intensity of securing band, climbers etc.Because advantages such as it is simple in structure, is power with the manpower, and service condition is unrestricted are popular in the same industry.
The shortcoming of this simple and easy tension tester is a function singleness, and can only do tensile test: range is less, can not detect for the Work tool of some higher-strengths; Measuring accuracy is low; Measurement range is narrow, can not detect large-scale Work tool.
The purpose of this utility model is in order to overcome above-mentioned deficiency, to provide a kind of simple in structure, and range is big, the multifunctional pull testing machine that function is more, measuring accuracy is high.
The utility model comprises frame, is fixed on pull bar and dynamometer on the frame, at the frame napex upper frame of placing tested rod member is arranged.
Also be provided with on the described upper frame by turning round wheel and at least two rod member stationary installations that are used to measure torsion that the deflation cover constitutes.The distance of these two deflation inner rooms can be regulated.
Upper rack of the present utility model is provided with the oblique stationary installation of rod member of the oblique anchorage force of measurement rod member that is made of adjustable plate, expansion link, fixed cover.
Also be provided with hydraulic pressure heavy load puller system on the frame with the range extension scope.
The utility model has the advantages that simple in structurely, measuring accuracy height, and because of being provided with the heavy load puller system increases range; Rod member stationary installation on upper frame and the upper frame and the oblique stationary installation of rod member on the frame make function of the present utility model increase.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a multifunctional pull proving installation left view.
Fig. 2 is a multifunctional pull proving installation front elevation.
With reference to accompanying drawing, the multifunctional pull proving installation is by frame 15, and the pull bar 16 and the dynamometer 12 that are fixed on the frame 15 are formed.When detecting operation, measured piece can be fixed on dynamometer 12 and the pull bar 16, hand pull bar 16, can from dynamometer read the pulling force that bears of tested test specimen, thereby whether it meets safety standard as can be known.Two arcs 5 are arranged at the middle part of frame, can be in order to the stressed safety case of test climbers.
Multifunctional pull proving installation of the present utility model has a upper frame 9 at frame 15 tops, can the tested rod member of horizontal positioned on this upper frame 9, and as ladder, control lever etc.On upper frame 9, also be provided with by turning round wheel 11, tightening the rod member stationary installation of overlapping the test rod member torsion of (8,10) forming.It at upper rack the oblique stationary installation of rod member of the oblique anchorage force of test rod member formed by adjustable plate 6, extensible member 7 and fixed cover (3,13).In order to remedy the pull bar 16 simple restrictions that rely on manpower to range ability, add a hydraulic pressure heavy load puller system in frame lower.This device is made up of lifting jack 1 slide bar 2 and drive link 4 application of force pull bars 18.
The dynamometer of the utility model multifunctional pull proving installation is by definite value control display instrument 14, and sensor 17 is formed.As required, also can connect a printer.
When detecting operation, can operate according to following steps.
1, detect resistance to bending: tested rod member is placed on the upper frame 9, and horizontal positioned is fixed on sensor 17 on the pull bar by the connecting hole on the pull bar, and the other end of sensor is by flexible connecting member, a certain position of straining tested rod member as iron wire.Hand pull bar, tested rod member are subjected to a downward pulling force, and the signal by sensor provides converts numerical value to and shows on definite value control display.If hand pressure can not satisfy the measured piece requirement, sensor can be fixed on the application of force pull bar 18, shake lifting jack 1, slide bar 2 upwards lifts, and drives drive link 4 and moves upward, at this moment, one end of application of force pull bar 18 upwards, the other end is downward, applies downward pulling force for simultaneously tested rod member, can read by sensor and display.For the ease of regulating stress point, between upper frame 9 and frame 15, adopt the rolling connected mode, the upper frame 9 that makes frame 15 relatively moves horizontally.
2, measuring staff spare torsion places deflation cover internal fixation with tested rod member two ends, applies downward pulling force by pull bar and sensor to turning round wheel, make and turn round the wheel rotation, drive rod member one end and rotate, simultaneously relative to the other end, this pulling force changes electric signal into by sensor, can read from display.
3, deviational survey is fixed on assigned position by fixed cover (3,13) with measured piece to anchorage force, by pull bar fixed cover 13 tops is applied pulling force.
