Detailed ways

As shown in Figure 1 and Figure 2, a rail vehicle contact type obstacle detection device, the detection device includes a detection beam 6, a toggle connecting plate 8, a travel switch 3 and two elastic supports 2 that are symmetrically arranged in a matching manner, so that Described elastic support 2 is m type. The detection beam 6 is fixed with two supporting square tubes 5 arranged symmetrically, and the supporting square tubes 5 are fixedly connected with the front end support arm 21 of the elastic bracket 2 . A limit plate 4 for limiting excessive deformation of the front support arm 21 is provided between the front support arm 21 and the rear support arm 22 of the elastic bracket 2 . One end of the limiting plate 4 is affixed to the rear end support arm 22 of the elastic support 2, and the other end of the limiting plate 4 is provided with a through groove 41, and the extension of the front end support arm 21 of the elastic support 2 passes through Through the groove 41. A mounting plate 9 is fixedly mounted on the limiting plate 4 , and the travel switch 3 is fixedly mounted on the mounting plate 9 .

The front end support arm 21 of the elastic bracket 2 is fixedly connected with a toggle connecting plate 8 , and the toggle connection plate 8 is fixedly connected to the extension of the front end support arm 21 of the elastic bracket 2 . The toggle connecting plate 8 is provided with a through hole 81, the rear end support arm 22 of the elastic bracket 2 is fixedly connected with the travel switch 3, and the travel switch 3 is provided with a dial pin 31, and the dial pin 31 is placed in the through hole 81.

A connection plate 7 is fixed on the extension of the front end support arm 21 of the elastic bracket 2 , and the connection plate 7 is provided with serrations, and the support square tube 5 is provided with serrations matching and meshing with the connection plate 7 .

The detection beam 6 is a hollow structure, which is beneficial to reduce the overall weight of the detection device.

The shape of the front end support arm 21 of the elastic bracket 2 is rectangle, trapezoid and rectangle from top to bottom.

In actual operation, the rear end support arms 22 of the two elastic brackets 2 are fixedly connected to the frame 1 of the rail vehicle respectively, and the detection beam can be adjusted by adjusting the sawtooth engagement relationship between the support square tube 5 and the connecting plate 7 6 distance from the track below. In rail vehicle implementation, the entire detection device advances with the vehicle, and when the detection beam 6 touches the obstacle 10 on the track, due to the interaction of forces, the detection beam 6 moves backwards, and the support on the detection beam 6 moves backward. The front end support arm 21 of the elastic bracket 2 to which the tube 5 is fixed also moves backward, and the deformation of the front end support arm 21 drives the toggle connecting plate 8 fixed thereon to move backward. In the through hole 81 of the toggle connecting plate 8, the backward movement of the toggle connecting plate 8 and the toggle pin 10 are triggered, thereby triggering the travel switch 3 to signal an obstacle.

The shape of the front end support arm 21 of the elastic support 2 is rectangle, trapezoid and rectangle from top to bottom. This structure allows the front end support arm 21 of the elastic support 2 to pass through the slot 41 of the limit plate 4 flexibly. And when the detection beam 6 hits the obstacle 10, the front end support arm 21 can be better deformed.

Example 2

As shown in FIG. 3 , the difference between this embodiment and Embodiment 1 is that the elastic support 2 is n-type.

The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the scope of the present invention. Variations and improvements should fall within the scope of protection defined by the claims of the present invention.
