Abstract
The utility model relates to a foot-operated switch testing stand, comprising a punch and a mounting plate fixedly connected with the punch, wherein the lower end of the mounting plate is provided with a stop collar and a spring sleeved onto the stop collar, the lower end of the spring is connected with a foot-operated punch, and a bottom plate at the lower end of the foot-operated punch is provided with a foot-operated switch to be tested. In the utility model, the punch moves up and down to drive the mounting plate and the foot-operated punch to move up and down, and when the foot-operated punch is contacted with the pedal of the foot-operated switch, the foot-operated punch stops moving and the stop collar presses the foot-operated punch member to enable the foot-operated switch to act. After the foot-operated switch acting, the punch moves upwards, and the foot-operated punch is kept for a certain time under the action of the spring, and then recovers to the original position of the foot-operated switch. According to the principle, the foot-operated switch testing stand performs mechanical life test on the foot-operated switch and makes a statistic for test frequency.
Description
Technical field
The utility model relates to a kind of foot-switch testing table.
Background technology
Foot-switch is the master controller of internal combustion, electric locomotive, electric motor car group, is to utilize the low-voltage electrical apparatus of control circuit to come the electrical equipment of control master control electrical apparatus indirectly.It mainly is used for controlling the utilization operating mode of locomotive.At present; Because the utilization operating mode of each locomotive is different; Caused the frequency of utilization of foot-switch of the same type on different locomotives to have than big-difference; And each locomotive depot to the supplementally taking of locomotive, in to repair with overhaul all be to carry out by the milimeter number of locomotive operation, so the higher foot-switch of part frequency of utilization possibly surpass the life-span of this foot-switch not to servicing time the time, brought hidden danger for the safe operation of locomotive.
Summary of the invention
The purpose of the utility model has been to provide a kind of foot-switch testing table that can test the foot-switch life-span.
For achieving the above object; The technical scheme that the utility model adopts is: comprise punch press and the installing plate that is fixedly connected with punch press; Be provided with stop collar and be sleeved on the spring on this stop collar in the lower end of installing plate; The lower end of spring is connected with foot-operated drift, and the base plate of foot-operated drift lower end is provided with foot-operated beginning to be measured.
Also be provided with relay on the base plate of described foot-operated drift lower end.
When the utility model moves up and down through the punch press drift, drive installing plate and move up and down, drive foot-operated drift and move up and down; When foot-operated drift touches the pedal of foot-switch; Foot-operated drift stop motion, stop collar press foot-operated drift spare, make foot-switch move.After the foot-switch action, the punch press drift moves upward, and foot-operated drift keeps the regular hour under the effect of spring, returns to the original position of foot-switch then.Principle foot-switch testing table carries out mechanical endurance test to foot-switch according to this, and carries out the statistics of test number (TN).
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model;
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Referring to Fig. 1; The utility model comprises punch press 1 and the installing plate 2 that is fixedly connected with punch press 1; Be provided with stop collar 3 and be sleeved on the spring 4 on this stop collar 3 in the lower end of installing plate 2; The lower end of spring 4 is connected with foot-operated drift 5, and the base plate of foot-operated drift 5 lower ends is provided with foot-operated beginning to be measured, on the base plate of foot-operated drift 5 lower ends, also is provided with relay 6.
When the utility model punch press 1 drift moves up and down; Driving installing plate 2 moves up and down with foot-operated drift 5; When foot-operated drift 5 touches the pedal of foot-switch; The stop motion of being obstructed of foot-operated drift 5, this moment, stop collar 3 continued to move downward compression spring 4 under the drive of installing plate 2, pressed foot-operated drift 5 and continued to move down and make the foot-switch action thereby drive.After the foot-switch action, after keeping wanting seeking time under the control of the time relay 6, the punch press drift moves upward and regulates the actuation time and the retention time of foot-switch testing table through auxiliary reclay 6; Thereby the operating frequency of control testing table; Under spring 4 effects, stop collar 3 moves upward earlier, returns to the original position of foot-switch then; The counter that be connected with foot-switch this moment is once counted, and drift returns to the original position under the control of the time relay.Principle foot-switch testing table carries out mechanical endurance test to foot-switch according to this, and carries out the statistics of test number (TN).Grasped the serviceable life of foot-switch; To different locomotives, different operating mode different requirement is proposed in the use of foot-switch; Before foot-switch loses efficacy, overhauled or changed; Thereby reduce the inefficacy of foot-switch, improved the safety and the reliability of foot-switch, improved the reliability in the auxiliary electrical loop of locomotive.
