Description
The present invention relates to the railway signal device, relate in particular to the force of switching mechanism tester.
The mechanical property of test track switch mainly contains two kinds of testing tools in the prior art.1. the track switch device for measuring force of Chinese railway science institute development uses the conversion power of axial pin type force sensor measuring goat by changing the pin at switch pole place.The force of switching mechanism tester will be changed pin, can only carry out in the time slot that no train passes through in actual use.Because changing pin, reasons such as effect of point tongue bounce and corrosion, deformation must use crank or crowbar in operation site, the very painstaking difficulty of this measure.This instrument structure complexity in addition, cost is higher.These make this instrument can not patrol and examine with current check in use.2. patent documentation CN2238176Y is by the conversion power of dynamometry crank test goat.According to the regulation that Ministry of Railways's crank uses, the use of this instrument and method of testing is subjected to strict restriction, so can't patrol and examine middle use in routine.The conversion resistance force of above-mentioned two kinds of methods and instrument measurement goat be not decision track switch could normal reliable the important parameter of conversion.To maintaining the important parameter that is difficult to provide directive significance.And be easy to the influence driving, be difficult to guarantee safety of railway traffic.
Task of the present invention provide a kind of simple in structure, cost is low, to the force tester of the difference of driving influence test goat pulling force little and easy to use and switch convert resistance.Especially can test the force tester of the difference of the maximum conversion resistance force of goat maximum pull and track switch.The power of the difference of goat pulling force and switch convert resistance is the important parameter that decision track switch could the normal reliable conversion in the process of test track switch mechanical property.The force tester of the difference by goat pulling force and switch convert resistance can be obtained this has directive significance to maintenance important parameter.Simultaneously in the track switch transfer process, it is stressed when being zero during the goat release, and by applying damping-force adjustable, the present invention can test the goat maximum pull.The power of the difference by the maximum conversion resistance force of test goat maximum pull and track switch can converse the maximum conversion resistance force of track switch.In the track switch transfer process, apply damping force, can the indirect review notch size.This is also very important to guaranteeing the reliable conversion of track switch.
In the track switch transfer process power of the difference of goat pulling force and switch convert resistance be decision track switch could normal reliable the important parameter of conversion.Task of the present invention provides a kind of force of switching mechanism tester of being made up of mechanical resistance Buddhist nun mechanism (4) and damping force applicator (6).Damping force applicator (6) is placed the coupling part of switch pole (10) and tongue (7) or places switch pole (10) to locate.By mechanical resistance Buddhist nun mechanism (4) and damping force applicator (6) goat is applied damping force in the switch with follow up movement transfer process.Detect the force tester and the method for testing thereof of the difference of goat pulling force and switch convert resistance with this.Especially the force of switching mechanism tester of being made up of force transducer (1), data processor (2), Displaying Meter (3), mechanical resistance Buddhist nun mechanism (4), damping force adjusting mechanism (5) and damping force applicator (6) places damping force applicator (6) coupling part of switch pole (10) and tongue (7) or places switch pole (10) to locate.By applying damping-force adjustable in the goat switch with follow up movement transfer process, make its output maximum pull up to conversion resistance force maximum point jam goat.Detect and show the power of the difference of goat maximum pull and the maximum conversion resistance force of track switch this moment by force transducer (1), data processor (2), Displaying Meter (3).The force tester of the difference of the maximum conversion resistance force of test goat maximum pull and track switch can patrol and examine with current check in timely discovering device hidden danger, obtain the important parameter that maintenance is had directive significance very easily, and need not change pin and other parts, simple, convenient, laborsaving, quick.This force tester and method of testing thereof do not need to use crank.The force tester of the difference of detection and demonstration goat maximum pull and the maximum conversion resistance force of track switch can reduce the influence to driving, guarantees safety of railway traffic.In the track switch transfer process, apply damping force, can the indirect review notch size.This is also very important to guaranteeing the reliable conversion of track switch.

Describe optimum implementation of the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 is the measuring principle figure that parallels to the axis of the present invention.Place switch pole (10) to locate damping force applicator (6), the tongue (7) and stock rail (8) outside.By mechanical resistance Buddhist nun mechanism (4) and damping force applicator (6) tongue (7) and stock rail (8) are applied damping force in goat switch with follow up movement transfer process.Also mechanical resistance Buddhist nun mechanism (4) and damping force applicator (6) can be placed each test position shown in Figure 6.Each group Ai, Bi are a point of application among the figure, all can implement test at each point of application.Test the power of the difference of goat pulling force and switch convert resistance with this.Fig. 2 is the structural representation of the force tester of the present invention's difference of testing goat pulling force and switch convert resistance.The force of switching mechanism tester of forming by mechanical resistance Buddhist nun mechanism (4) and damping force applicator (6).Mechanical resistance Buddhist nun mechanism (4) is made up of scalable fixed support and fixed force spring.Scalable fixed support is welded by shaped steel, or is formed by the metal material casting.Scalable fixed support two ends are damping force applicator (6) fixedly, or directly casts damping force applicator (6).The damping force of fixed force spring is the 500-15000 ox.Fixed force spring can be made up of the fixed force spring of one group or array 10N-500N.Place switch pole (10) to locate damping force applicator (6), the tongue (7) and stock rail (8) outside.By mechanical resistance Buddhist nun mechanism (4) and damping force applicator (6) tongue (7) and stock rail (8) are applied damping force in goat switch with follow up movement transfer process.Detect the power of the difference of goat pulling force and switch convert resistance with this.Determine to apply different damping forces according to dissimilar goats.So in the process of patrolling and examining, track switch is applied optimum damping power.If this track switch still can normally be carried out the track switch conversion, then some accidental external force change can not influence the track switch conversion.Thereby can reduce influence, guarantee safety of railway traffic driving.If this track switch can not normally be changed, then should in time be engaged in renovating, in case influence traffic safety together with the worker.Following table is goat damping force scope and the optimum damping power in the actual use.
