Detailed Description
The balance wheel is an important structure of the urban rail sliding plug door, is generally arranged on a vehicle body, and is tightly pressed on a press plate arranged on a door leaf when the sliding plug door is closed, so that a vehicle door is restrained. At the moment, a certain force is required to be applied to the circumferential direction of the balance wheel to enable the balance wheel to rotate
Example 1
As shown in fig. 1 and fig. 2, the detection apparatus for tightness adjustment of a balance wheel of a sliding plug door in the present embodiment includes a test piece 11 for bearing pressure of the balance wheel of the sliding plug door, a chuck 12 fixedly connected to one end of the test piece 11, and a tension measuring instrument 13, where the test piece 11 is a metal sheet or a non-metal sheet. Chuck 12 includes first connecting portion 121 and the second connecting portion 122 of fixed connection, first connecting portion 121 surface sets up the through-hole, and the through-hole is used for tensile measuring instrument 13's connection, and second connecting portion 122 includes clamping piece and lower clamping piece, goes up the clamping piece and forms the gap that holds test piece 11 down between the clamping piece, and adjusts the gap size between clamping piece and the lower clamping piece through screw 123, and test piece 11 is put into the gap between clamping piece and the lower clamping piece on frock chuck 12, screws up the test piece after the housing screw and is compressed tightly by the chuck, difficult pine takes off. The pulling hook of the tension measuring instrument 13 (digital display push-pull dynamometer) passes through the chuck through hole, applies tension to the test piece 11 through the chuck 12, and displays the tension indication number. The balance wheel can rotate with force, and the extraction force of the test piece pressed by the balance wheel can be quantified.
Example 2
As shown in fig. 3 or 4, the detection assembly for tightness adjustment of the balance wheel of the sliding plug door in the present embodiment is characterized by comprising the detection device 1 in embodiment 1, a sliding plug door balance wheel 2 and a pressing plate 3, wherein when the vehicle door is closed, the test piece 11 is pressed by the balance wheel 2 and the pressing plate 3, and the tension measuring instrument is used for displaying the tension for pulling the test piece 11 out of the sliding plug door balance wheel 2.
