Embodiment 1

[0024] See Figure 1-2, a driving anti-derailment device that can dynamically monitor the state of the track, including a track 1 and a chassis mechanism 3, the bottom end of the chassis mechanism 3 is fixedly connected with a wheel mechanism 2 that matches the track 1, and the bottom end of the chassis mechanism 3 is left and right Both sides are symmetrically fixedly connected with a bracket 4 matching with the wheel mechanism 2, the bracket 4 is a U-shaped structure, two brackets 4 are arranged on the inner side of the track 1, the bracket 4 is sleeved on the outside of the wheel mechanism 2, and the bracket 4 The side wall of the inner cavity is fixedly connected with a laser displacement sensor 5 matched with the wheel mechanism 2 and a laser profile sensor 6 matched with the wheel mechanism 2, and the laser displacement sensor 5 is arranged above the laser profile sensor 6. The middle part of the bottom end of the chassis mechanism 3 is fixedly equipped with a control de...

Embodiment 2

[0026] See Figure 3-4 The difference from Embodiment 1 is that: the top of the bracket 4 is provided with a shock-absorbing groove 41, and the inner cavity bottom wall of the shock-absorbing groove 41 is uniformly and fixedly connected with a plurality of second telescopic rods 42, and the second The top end of the telescopic rod 42 is fixedly connected to the bottom end of the chassis mechanism 3, and the outer side of the second telescopic rod 42 is provided with a pre-tension spring 43 matched with the damping groove 41, and the end of the pre-tension spring 43 is fixedly connected to the The bottom end of the chassis mechanism 3, the bottom end of the support 4 is symmetrically fixedly connected with a guide plate 44, the guide plate 44 is made of an elastic material, the guide plate 44 is a semicircular plate, and the arc of the guide plate 44 The surface is evenly provided with some shock absorbing plates 45, and guide wheels 46 are fixedly installed on the shock absorb...

Embodiment 3

[0028] See Figure 5 , the difference from Embodiment 2 is that: the arc surface of the guide plate 44 is evenly provided with a number of shock absorbing holes 441, the shock absorbing plate 45 is slidably connected in the shock absorbing holes 441, and the inner end of the shock absorbing plate 45 A third telescopic rod 442 is fixedly connected, and the other end of the third telescopic rod 442 is fixedly connected to the inner cavity top wall of the shock-absorbing hole 441. The outer side of the third telescopic rod 442 is provided with a Shock absorbing spring 443, the end of described shock absorbing spring 443 is fixedly connected to the inner cavity top wall of shock absorbing hole 441, cooperates shock absorbing spring 443 by the 3rd telescoping rod 442, can effectively improve the shock absorbing of guide wheel 46, The cushioning effect prevents the guide wheel 46 from being damaged by collision, thereby improving the service life of the guide wheel 46 .

Abstract

The invention discloses a train anti-derailing device capable of dynamically monitoring a track state. The device comprises a track and a chassis mechanism, wherein the bottom end of the chassis mechanism is fixedly connected with wheel mechanisms, the left side and the right side of the bottom end of the chassis mechanism are symmetrically and fixedly connected with brackets matched with the wheel mechanisms, the side walls of inner cavities of the brackets are fixedly connected with laser displacement sensors matched with the wheel mechanisms and laser contour sensors matched with the wheelmechanisms, a control device is fixedly installed in the middle of the bottom end of the chassis mechanism, and stabilizing mechanisms are arranged on the left side and the right side of the bottom end of the chassis mechanism. According to the device, the laser displacement sensors and the laser contour sensors dynamically detect the track along with travelling of a whole train, then the controldevice extends a first telescopic rod out through an electric telescopic device, and then presses an upper top wheel and a side top wheel on the track, external stress points between the whole train and the track are increased, the stability between the whole train and the track is increased, so that the whole train is guaranteed to operate stably or park smoothly.

Description

technical field [0001] The invention relates to the technical field of driving derailment prevention, in particular to a driving derailment prevention device capable of dynamically monitoring the track state. Background technique [0002] Railway track, referred to as rail, rail, track, etc. It is used on the railway and cooperates with the switch, so that the train can walk without turning. The track usually consists of two parallel steel rails. The rail is fixed on the sleeper, and the ballast is under the sleeper. Rails made of steel can withstand greater weight than other materials. Sleepers, also known as sleepers, or road sleepers, function to separate and distribute the weight of the rails and keep the rails fixed and maintain the gauge of the rails. Generally, the bottom of the track is ballast paved with gravel. Ballast, also known as ballast, crushed stone or ballast bed, provides flexibility and drainage for the track. Tracks can also be laid on concrete bas...
