Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
The structure of thunder arrester mechanical fatigue test machine provided by the invention is as shown in Figure 1, comprise base 1, base 1 is respectively arranged with worktable 2 and bracing frame 6, bracing frame 6 top is provided with lifting motor 7, it is perpendicular to base 1 and also it is respectively arranged with guide rail 3 and elevating screw 8, the top of guide rail 3 is connected with bracing frame 6 respectively with the top of elevating screw 8, guide rail 3 is connected with travel(l)ing rest 5, travel(l)ing rest 5 is provided with coupling device 4, coupling device 4 is also connected with elevating screw 8, coupling device 4 is provided with servo electric jar 10, servo electric jar 10 is connected by wire with lifting motor 7.
As shown in Figure 2, also comprise the stop means 9 being arranged on bracing frame 6 sidewall, stop means 9 comprises the vertical slot 91 being arranged at respectively on bracing frame 6 two sidewalls, the inner side at the two ends up and down of two vertical slots 91 respectively correspondence be provided with limit switch 93, being connected by cross bar 92 between two vertical slots 91, cross bar 92 is through coupling device 4.
Guide rail 3 and elevating screw 8 are respectively arranged with two, and two guide rails 3 are connected with travel(l)ing rest 5 moving up and down jointly, and two elevating screws 8 are connected with coupling device 4 jointly.
Being sheathed with gripping unit 11 respectively on two guide rails 3, two gripping units 11 are arranged at the lower end of travel(l)ing rest 5, and gripping unit 11 is rubber item.
Guide rail 3 is cylindrical.
As shown in Figure 3, worktable 2 is circular, worktable 2 central authorities are provided with thunder arrester insert stand 21, and worktable 2 is evenly provided with even number groove 22 along its diameter direction, be provided with in each groove 22 one be connected with thunder arrester insert stand 21 and in groove 22 movement pull device 23.
Being electrically connected by the device 23 that pulls arranged in vertical supervisory control desk and groove 22, vertical supervisory control desk pulls device 23 to move in groove 22 by electrical connection control.
By fixing in the thunder arrester insert stand 21 of the lower end of thunder arrester 12 to be tested insertion worktable 2 central position, startup lifting motor 7 controls servo electric jar 10 and works, servo electric jar 10 controls ball-screw 8 by coupling device 4 and slowly accurately moves, now travel(l)ing rest 5 moves on guides 3, when the coupling device 4 on travel(l)ing rest 5 contacts with thunder arrester 12 to be tested, then lifting motor 7 stops work, by coupling device 4, thunder arrester 12 upper end to be tested is fixed, the contact that the thunder arrester 12 of different heights carries out high precision can be fixed like this, and avoid and thunder arrester 12 is caused deformation thus affects test effect, pull device 23 to haul thunder arrester insert stand 21 finally by the control of vertical supervisory control desk to move around thunder arrester 12 bottom in thunder arrester insert stand 21 is swung back and forth, by simulating thunder arrester 12 swing process under normal circumstances like this, the data of the mechanical fatigue of thunder arrester 12 in swing process can convert the display screen display of sinusoidal waveform figure at vertical supervisory control desk to, the mechanical fatigue situation of thunder arrester 12 just can be obtained by analyzing this sinusoidal waveform figure, and fit gripping unit 11 on guides 3 in travel(l)ing rest 5 bottom can play in thunder arrester 12 swing process the buffer protection of whole device and fixing effect, prevent firmly touching between travel(l)ing rest 5 with guide rail 3.
When coupling device 4 moves up and down, also cross bar 92 correspondence through it can be driven to move up and down, when cross bar 93 moves to the two ends up and down of vertical slot 91, touching the limit switch 93 being positioned at vertical slot 91 two ends, limit switch 93 can give the alarm and remind operator to note.
