Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figures 2 to 5, electromagnetic track brake electromagnetic attraction Detecting data of the present utility model comprises hydraulic jack 1, pedestal 2, multiple spacing column 3 and Hoisting tackle 4; Hydraulic jack 1 is positioned at the workspace of testing table, and its head is provided with the sensor for detecting electromagnetic track brake 5 electromagnetic attraction; Pedestal 2 is provided with rail 2-1 at the work area position of testing table, and pedestal 2 is equipped with slideway 2-2 in the both sides of rail 2-1, and slideway 2-2 extends to nonclient area from the workspace of testing table; Multiple spacing column 3 is the symmetrical both sides being fixed on pedestal 2 between two, and each spacing column 3 is equipped with pin-and-hole; The wheel of Hoisting tackle 4 is placed on slideway 2-2, and Hoisting tackle 4 is equipped with mounting-positioning holes 4-1 in the both sides of its front-end and back-end, and is provided with locating piece 4-2 in the both sides of mounting-positioning holes 4-1.
Pedestal 2 is the matrix framework of whole testing table, is steadily placed on level ground, and on pedestal 2, the gauge of rail 2-1 is 1435mm.Hoisting tackle 4 is for hanging electromagnetic track brake 5, and when hydraulic jack 1 works, its connected mode is for being rigidly connected.
The course of work of the utility model electromagnetic track brake electromagnetic attraction Detecting data is: first Hoisting tackle 4 is placed in inoperative assembling district (as shown in Figure 4), in inoperative assembling district, the mode of fixing with the first register pin 5-3 after passing the mounting-positioning holes 4-1 of Hoisting tackle 4 by the piston of piston type cylinder 5-1, electromagnetic track brake 5 to be detected is connected with Hoisting tackle 4, then move to workspace (as shown in Figure 3), with the second register pin, Hoisting tackle 4 is fixed on spacing column 3; Electromagnetic track brake 5 is connected DC110V power supply, after energising, electromagnetic track brake 5 and rail 2-1 adhesive, now complete the action of electromagnetic track brake 5 and rail 2-1 adhesive, wherein, the effect of piston type cylinder 5-1 is mainly its telescopic piston and completes an action moved down together with electromagnetic track brake 5, and Hoisting tackle 4 keeps maintaining static by the second register pin and spacing column 3; Cancel the first register pin 5-3 and piston type cylinder 5-1, use instead and substitute the piston of piston type cylinder 5-1 through Hoisting tackle mounting-positioning holes 4-1 with the rigid connector 5-2 identical with piston type cylinder 5-1 piston overhang, electromagnetic track brake 5 and Hoisting tackle 4 are connected; Cancel the second register pin simultaneously, Hoisting tackle 4 is not connected with spacing column 3; Risen by hydraulic jack 1, the sensor of hydraulic jack 1 is contacted with Hoisting tackle 4, hydraulic jack 1 continues to rise, and spacing column 3 can be to move up and leads, until jack-up Hoisting tackle 4, namely electromagnetic track brake 5 departs from rail 2-1, sensor gathers now data value, transfers to computing machine, according to the deadweight of electromagnetic track brake 5 and the deadweight of Hoisting tackle 4, by calculating, draw the electromagnetic attraction of electromagnetic track brake 5.
As shown in Figure 5, the A type project organization of Hoisting tackle 4 can be connected with the hydraulic jack of horizontal positioned, realizes the detection of electromagnetic track brake horizontal friction force.The syndeton that the Type B project organization of Hoisting tackle 4 is models of using for Changchun Light Rail 70% low floor vehicle is HS66 type electromagnetic track brake.Therefore, the structural shape of Hoisting tackle 4 can be designed to multiple pattern, or designs multiple connecting interface simultaneously, meets the connection of different model electromagnetic track brake, realizes the detection of electromagnetic attraction.
