Fixing device for a ladder car on a rail

technical field

The utility model relates to the technical field of a rail ladder car, in particular to a fixing device for a ladder car on a rail.

Background technique

In the construction and maintenance of electrified catenary, ladder cars are often used for high-altitude operations. The height of ladder cars is usually more than 3 meters. In order to facilitate manual handling, ladder cars are generally made of light materials. The base is narrow along the vertical direction of the steel rail and the vehicle body is high, which may easily cause the ladder car to roll over during use and cause injury to the operating personnel. Therefore, when the ladder car is working, the traditional method requires 4 people to escalate the ladder under the ladder car to prevent rollover, and use objects to pad under the wheels to prevent the ladder car from moving along the rails, which increases labor intensity and may delay the construction period.

The clamping mechanism of the car base includes an upper splint and a lower splint fixedly connected by bolts, and a clamping groove for clamping the steel pipe on the base of the ladder car is opened between the upper splint and the lower splint; the rail clamping mechanism includes a rail head An inverted U-shaped groove at the top of the U-shaped groove. The end of the side wall of the U-shaped groove is bent toward the waist of the rail, and the side wall on the other side is provided with a threaded hole, and a screw for clamping the waist of the rail is arranged in the threaded hole.

Preferably, the connecting rod is an externally threaded rod, the clamping mechanism of the ladder car base is threadedly connected with the connecting rod through the nut provided on the upper splint, and the rail clamping mechanism is provided with a The connecting plate of the internally threaded hole is threadedly connected with the connecting rod.

Preferably, the end of the connecting rod on one side of the rail holding mechanism is provided with a limit ball head with a diameter larger than that of the connecting rod body.

Preferably, the clamping groove on the clamping mechanism of the ladder car base is opened on the bottom surface of the upper splint, and its cross section is an isosceles triangle.

Preferably, the end of the side wall bent toward the waist of the rail on the U-shaped groove and the end of one end of the screw rod located in the U-shaped groove are both provided with a top plate, and the end of the screw rod located at one end outside the U-shaped groove There is a handle on the inside.

Beneficial effect

One end of the fixing device of the ladder car on the rail of the utility model is fixed to the steel pipe on the ladder car base through the clamping mechanism of the ladder car base, and the rail clamping mechanism at the other end is fixed to the waist of the rail and covers the whole rail. The head prevents tripping, firmly fixes the ladder car and the rail, effectively prevents the ladder car from turning over, and the distance between the two clamping mechanisms is adjustable, and the clamping mechanism of the ladder car base is used to clamp the ladder car base The clamping groove distance of the steel pipe can be adjusted, which is suitable for various ladder cars of different specifications.

detailed description

As shown in Figure 1, a fixing device for a ladder car on the rails of the utility model, by firmly connecting the steel pipes 7 on both sides of the base of the ladder car with the corresponding rails 9, can effectively prevent the ladder car from turning over. The device comprises a connecting rod 1 with an external thread and a ladder car base clamping mechanism 2 and a rail clamping mechanism 3 connected by the connecting rod 1. The end of the side is provided with a limit ball head 14 whose diameter is larger than the main body of the connecting rod 1 to prevent the rail clamping mechanism 3 from falling off from the connecting rod 1 when the utility model is in use.

The clamping mechanism 2 for the base of the ladder car is used to fix the steel pipe 7 on the base of the ladder car, including an upper clamping plate 5 and a lower clamping plate 6 fixedly connected by bolts 4, wherein a nut 12 is arranged on the upper clamping plate 5, and the nut 12 is connected with the The connecting rod 1 is connected, and a clamping groove 8 is provided between the upper clamping plate 5 and the lower clamping plate 6. The lower clamping plate 6 in this embodiment is a flat plate, and the clamping groove 8 is opened at the bottom of the upper clamping plate 5. The clamping groove 8 The cross-section is an isosceles triangle, which is suitable for clamping steel pipes 7 of different specifications.

The rail clamping mechanism 3 is used to fix the rail 9, including an inverted U-shaped groove 10 that accommodates the head of the rail 9, and the U-shaped groove 10 is provided with a connecting plate 13 that offers internally threaded holes, and through the connecting plate 13 is connected with the connecting rod 1, the end of the side wall of the U-shaped groove 10 is bent toward the waist of the rail 9, and the end is provided with a top plate 15, which clamps the waist of the rail 9 from one side, and the side of the other side The wall is provided with a threaded hole, and the threaded hole is provided with a screw 11 for clamping the waist of the rail 9 from the other side, and the end of the side of the screw 11 is also provided with a top plate 15, so that the rail clamping mechanism 3 is enlarged to match the rail 9. The contact area of the waist is more stable, and the end of the other side of the screw 11 is provided with a handle 16, which is convenient for manually rotating the screw 11 to adjust the stroke of the screw 11. The rail clamping mechanism 3 clamps the waist of the rail 9, and the head of the rail 9 The mode of partial wrapping, prevents from tripping off on steel rail 9.
