Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, apparatus of the present invention comprise a support 1, and one end of support 1 vertically arranges a fixed head 2, are arranged at intervals with four bolts hole 21 that connect hand brake on fixed head 2, the bottom of fixed head 2 is provided with an opening 22, and opening 22 places are provided with certain pulley support 3.As shown in Figure 3, fixed pulley bearing 3 both sides are respectively arranged with a bearing 31, are rotationally connected a rotating shaft 4 in two bearings 31, are fixedly connected with a fixed pulley 5 in rotating shaft 4.As shown in Figure 2, the other end of support 1 is fixedly connected with a mount pad 6, is arranged at intervals with some brace rods 7 between the outside of mount pad 6 and support 1; Mount pad 6 inner sides are fixedly connected with a draw ring 8.As shown in Figure 4, on draw ring 8, hang one end of a tension spring 9, the other end of tension spring 9 connects a chain drop handle 10, and the other end of chain drop handle 10 connects one end of an adjusting yoke 12 by a round pin 11, and the other end of adjusting yoke 12 connects another chain drop handle 14 by another round pin 13.
In above-described embodiment, the main body of support 1 is formed by the grooved steel assembly welding of different size, to meet the strength and stiffness requirement of test unit.Tension spring 9 produces damping force when hand brake is tested, and therefore can need to arrange a plurality of according to test.Adjusting yoke 12 also can arrange many, in test, can, according to the hand brake of different chain lengths, select corresponding adjusting yoke 12.
Using method when as shown in Figure 5, Figure 6, apparatus of the present invention are tested NSW type hand brake comprises the following steps:
1) with screw bolt and nut, hand brake is fixedly connected on fixed head 2, the chain of hand brake is walked around to fixed pulley 5, and be hung on chain drop handle 14.
