Description

Durability test tool for isolation lock of rail train door

Technical Field

The utility model relates to an experimental frock especially relates to a track train door keeps apart lock endurance test frock.

Background

The train door is an important component of the whole train, the safety use performance of the train door must be guaranteed, and particularly the train door is guaranteed to be in a reliable closing state in the running process of a train. In the running process of the train, if an abnormal condition that one train door is closed or opened is found, and the fault condition cannot be eliminated immediately, the isolation lock needs to be manually set to the isolation state by an isolation lock key in the condition. The handling can ensure that the train continues to run normally, and meanwhile, the train door is not opened abnormally in the running process of the train, so that the safety of passengers is effectively ensured. The isolation state of the train door can realize two effects, and the disposal mode not only can effectively cut off the opening and closing signals received by the fault train door, but also can realize mechanical locking of the train door. After the above treatment is completed, the train door with the fault can be overhauled in detail after the train operation is finished, and the fault of the train door can be thoroughly removed. In summary, the importance of the isolation lock for safe driving of the train is quite high, and therefore the reliability requirement of the isolation lock itself is also high. To ensure high reliability of the isolation lock, an endurance test is required, and the design work of the endurance test tool is necessary work.

The existing commonly used isolation lock endurance test tool mainly uses a motor as a driving element, and the motor driving tool is complex in structure and relatively high in cost. Due to the characteristics of the driving motor, the rotating motion of the output shaft of the motor needs to be converted into the isolation and reset functional states of the isolation lock, so that the structural design of the tool is complex, and the design cost is increased. Simultaneously, because the cost of motor is high for the cylinder, choose for use the motor as drive element can make whole frock equipment cost increase.

The isolation lock key is connected with the sliding block through a screw, and slides through the sliding block to drive the isolation lock key to rotate, so that the isolation and reset functions of the isolation lock are realized.

The air cylinder is fixed on the aluminum profile through the air cylinder fixing seat, the installation position of the air cylinder fixing seat on the tooling platform can be adjusted, and the test operation can be in the best state through position adjustment.

The long bending plate is provided with a travel switch on the support far away from one side of the aluminum profile, the travel switch is connected with a counter, after the slide block touches the travel switch, the travel switch transmits a signal to the counter, and the counter can be used for recording the cycle number of the endurance test.

The travel switch is connected with the counter, when the slide block touches the travel switch, the travel switch transmits a signal to the counter, and the counter can be used for recording the cycle number of the endurance test.

The support is built by aluminum profiles.

Has the advantages that: the utility model discloses make full use of movement track's conversion, through three-dimensional design software simulation, confirm the movement track of frock moving part, convert the straight reciprocating motion of cylinder rod into the rotation isolation and the action that resets of isolation lock, for the frock that uses the motor as drive element usually, the frock overall structure as drive element with the cylinder is more simple, can be in order to realize required experimental requirement with simple frock structure, the overall structure of experimental frock is simpler more, the stability of frock also can be higher.

fig. 2 is an illustration adopting the utility model discloses a durability test frock makes isolation lock be in the schematic diagram of reset state.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model discloses a build the support that forms by the aluminium alloy, support top installs isolation lock main part appearance 1 and aluminium alloy 10, and isolation lock main part appearance 1 one end is through bending short slab 3, the other end through bending long slab 13 and leg joint, and aluminium alloy 10 passes through connecting plate 12 and leg joint. Be connected with backup pad 11 between isolation lock main part sample 1 and the aluminium alloy 10, slide platform 7 is installed at backup pad 11 top, isolation lock main part sample 1 top is installed and is kept apart lock key 2, keep apart lock key 2 and be connected with slider 5 through screw 6, the one end of slider 5 is rotated and is connected with cylinder 4, it slides on slide platform 7 to drive slider 5 through cylinder 4 is flexible, and then drive and keep apart lock key 2 and rotate, realize the isolation and the reset function of isolation lock.
