Problems solved by technology

Ballastless track is commonly used in high-speed railways. Ballastless track refers to the track structure that uses concrete, asphalt mixture, etc. There is a big difference in the structure of the ballast bed, and there is no side slope. When the vehicle derails, it is very easy to shift the center, and an overturning accident occurs to the lateral side, causing serious losses. Therefore, it is necessary to install an overturning device on the flaw detection vehicle.

Embodiment 1

[0022] see figure 1 As shown, the anti-overturning device applied to the electric rail flaw detection vehicle in this embodiment includes the axle shaft 1, the traveling wheels 2 of the electric rail flaw detection cart installed at both ends of the bridge axle 1, and the outer sides of the traveling wheels 2 installed on both sides respectively. Wheels 3.

[0023] The wheels 3 can be pivotably fixed on the outside of the road wheels 2, such as the wheels 3 are fixed on the end of the axle 1 through bearings, and the wheels 3 can rotate around the axle 1.

[0024] Described wheel 3 also can be directly fixed on the outside of road wheel 2, as wheel 3 is fixed on the end of axle shaft 1, or wheel 3 is fixed on the road wheel 2.

[0025] The outer rim of the wheel 3 has a rib 32 , and the distance between the outer side of the traveling wheel 2 and the inner side of the rib 32 is greater than the width of the upper part of the rail 4 .

Embodiment 2

[0028] see image 3 As shown, the anti-overturning device applied to the electric rail flaw detection vehicle in this embodiment includes the axle shaft 1, the traveling wheels 2 of the electric rail flaw detection cart installed at both ends of the bridge axle 1, and the outer sides of the traveling wheels 2 installed on both sides respectively. Wheels 3.

[0029] For the convenience of installation, a connecting rod 5 is fixed on the inner side of the wheel 3, and the other side of the connecting rod 5 is fixed on the outer end of the bridge shaft 1 or the outer end of the walking wheel 2. The fixing method can be welding or screw locking or other strong connections. Of course, the connecting rod 5 and the wheel 3 can also be integrally formed.

[0030] The outer rim of the wheel 3 has a rib 32, and the distance between the outer side of the traveling wheel 2 and the inner side of the rib (32) is greater than the width of the upper part of the rail 4.

Abstract

The invention discloses an overturn-preventing device applied to an electric rail-defect detector car. The overturn-preventing device comprises a bridge shaft (1) and traveling wheels (2), wherein the traveling wheels (2) for the electric rail-defect detector car are installed at the two ends of the bridge shaft (1); the overturn-preventing device is characterized in that the overturn-preventing device further comprises wheel bodies (3) are stalled on the outer sides of the traveling wheels (2) which are installed on the two sides of the bridge shaft (1), a blocking edge (32) is installed on the outer wheel edge of each wheel body (3), and distances between the outer side faces of the traveling wheels (2) and the inner side faces of the blocking edges (32) are larger than the width of the upper portion of a rail (4). The invention further discloses a rail-defect detector car frame of the overturn-preventing device applied to the electric rail-defect detector car. Compared with the prior art, the overturn-preventing device applied to the electric rail-defect detector car has the following advantages that when the rail-defect detector car runs off the rail, owing to the fact that a car body is stopped to make further transverse movement by wheel edge blocking sides of the overturn-preventing device, finally the rail-defect detector car is stopped under the effect of friction, so that overturn of the rail-defect detector car is prevented, and accident occurrence is avoided.

Description

technical field [0001] The invention relates to a rail flaw detection vehicle, in particular to an anti-overturning device applied to an electric rail flaw detection vehicle. Background technique [0002] The rail flaw detection vehicle is a special vehicle equipment for detecting fatigue defects and welding defects within the rail head and rail waist (including near the joint), as well as rail bottom corrosion, crescent block falling, rail head crushing and other damages. At present, various small and portable rail flaw detection vehicles manually propelled in China have the characteristics of small size and flexibility, but because they are used for rail flaw detection between two trains, and the weight of the whole vehicle is generally 100 kg. above. [0003] Patent application number 201320347294.6 discloses a portable and detachable rail flaw detection car frame, which includes a drive axle with drive wheels installed at both ends and a drive axle package connected bet...
