technical field

The utility model relates to a rail flaw detection car, in particular to an anti-overturning device on a rail ultrasonic flaw detection car.

Background technique

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.

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 between them, and a driven axle with driven wheels installed at both ends, installed on the drive axle. The frame base frame on the bridge and the driven axle, the front and rear ends of the left and right members of the frame base frame (1) and the drive axle and the driven bridge (12) are respectively clamped by a piece The fixing seat (8) that matches the lower end faces of the left and right members and the upper end faces of the driving axle and driven axle, and the upper end faces of the left and right members corresponding to the fixing seat, are snapped together with the left and right sides respectively. The locking seat (9) on which the upper end faces of the components match, the U-shaped screw rod (7) passes through the screw holes provided on the fixing seat and the locking seat from bottom to top respectively from the lower end faces of the driving axle and the driven axle, and is fixed by a nut. The connection is fixed. The safety and stability of the on-rail detection of the rail flaw detection vehicle are improved. However, although this structure is convenient for safe and fast disassembly and assembly, and can maintain the stability of the whole vehicle, the weight of the whole vehicle of the rail flaw detection vehicle is still very heavy.

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.

detailed description

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.

Please refer to Fig. 1, the anti-overturning device on the rail ultrasonic flaw detection vehicle of the present embodiment includes a bridge shaft 1, the traveling wheels 2 of the rail flaw detection vehicle installed at both ends of the bridge shaft 1, and the traveling wheels 2 installed on both sides respectively. Baffle device 3.

The baffle device 3 can be pivotably fixed on the outside of the road wheel 2, such as the baffle device 3 is fixed on the end of the bridge shaft 1 through a bearing, and the baffle device 3 can rotate around the bridge shaft 1.

Or described baffle device 3 also can be directly fixed on the outside of road wheel 2, as the end that the smaller diameter of baffle device 3 is fixed on the end of axle shaft 1, or the lesser end of diameter of baffle device 3 is fixed On walking wheels 2.

Specifically, the baffle device 3 includes a baffle 32 located on the outside and an installation shaft 34 fixed to the inside of the baffle 32. The diameter of the baffle 32 is larger than the diameter of the installation shaft 34, and the periphery of the baffle 32 is higher than the installation shaft. The outer surface of the shaft 34 and the baffle plate 32 are generally circular. The distance between the outer side of the road wheel 2 and the inner side of the baffle 32 is greater than the width of the upper part of the rail 4 .

Preferably, the baffle plate 32 can be coaxial or not coaxial with the installation shaft 34 .

Preferably, the baffle 32 and the installation shaft 34 are welded together, or the baffle 32 and the installation shaft 34 are integrally formed.

When the baffle device 3 can be pivotally fixed on the outer side of the road wheel 2, the mounting shaft 34 is fixed on the end of the bridge shaft 1 through a bearing, and the baffle device 3 can rotate around the bridge shaft 1.

When the baffle device 3 can be fixed on the outer side of the road wheel 2 , the installation shaft 34 is fixed on the end of the axle shaft 1 or on the road wheel 2 .

When the rail flaw detection vehicle is in normal operation, the two traveling wheels 2 rotate on the corresponding side rails 4 respectively. When the rail flaw detection vehicle derails due to an accident, as shown in Figure 2, due to the effect of inertia, the rail flaw detection vehicle will move toward a horizontal direction. Side tilting, at this time, the baffle device 3 on the side of the traveling wheel 2 in the opposite direction of inclination falls on the rail 4, because the baffle device 3 has a baffle 32 and an installation shaft 34, and the installation shaft 34 is against the top of the rail 4 On the surface, the baffle plate 32 is stuck on the outer side of the rail 4, which prevents the further tilting of the rail flaw detection vehicle, and because the traveling wheels 2 on both sides are detached from the track, the rail flaw detection vehicle will eventually stop under the action of frictional resistance. Prevent overturning from happening.

The baffle device 3 adopts a simple baffle 32 and installation shaft 34 structure, which reduces the weight of the whole vehicle to the greatest extent, prevents the overturning of the rail flaw detection vehicle, and avoids accidents.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
