Abstract
The utility model relates to a machine for testing the service life of brake soft tube of railway vehicles. In order to provide a machine for testing the service life which takes account of the action of the shaking force of vehicles and the influence of natural conditions, the utility model discloses a brake hose fatigue-testing machine of railway rolling stock which comprises a light source and a vibration source, wherein, the brake hose fatigue-testing machine of railway rolling stock uses an ultraviolet lamp with a 220-volt source, and the vibration source is composed of a prime mover, a gearing device and a crank link mechanism.
Description
The utility model belongs to and applies alternating bending power examination solid material under ultraviolet ray, high temperature and the ozone environment condition, particularly the fatigue tester in rolling stock air-brake coupling hose serviceable life.
The rolling stock air-brake coupling hose in use for some time, under the effect of vehicle shaking force and effect of natural conditions under, fatigue aging bends.Be examination flexible pipe serviceable life, the domestic automobile industry adopts the vibratory test platform examination automobile brake flexible pipe serviceable life of simple simulation vibrations; This testing table is not considered the influence of natural conditions, and is external, then introduced a kind of testing machine that adopts the low-tension supply quartz burner to make light source irradiation test hose material performance as the Soviet Union, and this testing machine can not be examined flexible pipe serviceable life.
For a kind of vehicle shaking force effect of both having considered is provided, consider the testing machine in rolling stock air-brake coupling hose serviceable life of effect of natural conditions again, the utility model is proposed.
The utility model is made up of light source and vibroseis two parts.Light source is for using the quartz burner of 220 volts of power supplys, and vibroseis is made up of prime mover, gearing and toggle.
The utility model vibroseis guarantees the amplitude of flexible pipe with 45 ° ± 2 ° of angles, 50 times/minute frequency alternating bending, flexible pipe is under the simulation rolling stock vibrations condition, bear alternating bending power, because the light source that the utility model adopted is the quartz burner of 220 volts of power supplys, flexible pipe is in than intensive ultraviolet, the environmental baseline of high-concentrated ozone and imitation summer climate temperature, thereby make flexible pipe quick, strengthen aging, examine out within a short period of time and both considered the effect of vehicle shaking force, consider the flexible pipe serviceable life of effect of natural conditions again, reach the utility model purpose.
Fig. 1 is the utility model structural representation
Fig. 2 is an A-B-D sectional view among Fig. 1
Fig. 3 is the utility model vibroseis principle of work synoptic diagram.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The utility model is made up of light source 1 and vibroseis 2, and light source 1 is 2538A ° quartz burner for 220 volts of voltages, wavelength; Vibroseis 2 is by prime mover, preferably motor 3, gearing 4 and toggle 5 are formed, gearing 4 has input shaft and is connected with motor 3 through shaft coupling 6, the reducer casing 8 that output shaft is connected with belt gear 7, the crank 10 of toggle 5 is housed on the output shaft 9 of belt gear 7, the other end and fork 13 usefulness bearing pins 14 that one end and crank 10 usefulness bearing pins 11 are articulated in the connecting rod 12 that A orders are articulated in the B point, the middle part C point of fork 13 is hinged on the casing 16 of vibroseis 2 through bearing pin 15, one end of the other end of fork 13 and flexible pipe 17 is fixedly connected on the D point, and the other end of flexible pipe 17 is fixedly mounted on the casing 16 of vibroseis 2.Crank 10 length (OA) are 75～82.5 millimeters, are preferably 80 millimeters; Connecting rod 12 length A B are 75～82.5 millimeters, are preferably 80 millimeters; The BC segment length of fork 13 is 105～120 millimeters, is preferably 110 millimeters; The CD segment length of fork 13 is 245～263 millimeters, is preferably 250 millimeters.
When examining flexible pipe serviceable life, when carrying out repeated bend test, open light source 1, quartz burner produces than intensive ultraviolet, high-concentrated ozone and 35 ° ± 5 ℃ summer climate temperature; Actuating motor 3, power reaches on the toggle 5 through reducer casing 8, belt gear 7, fork 13 is swung around hinge C, and drive the swing amplitude of 45 ° ± 2 ° in flexible pipe 17 works that are articulated in D with it, flexible pipe 17 is under the effect of simulating vehicle shaking force and the reinforcement torture test under the effect of natural conditions, until fatigue limit, thereby examine out flexible pipe serviceable life.
