Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-3, a rail-gnawing prevention crane comprises a main beam 1, a walking track 6, and a hoisting mechanism and a hanger which are arranged on the main beam 1, wherein the bottom of the main beam 1 is provided with a walking wheel 5 corresponding to the walking track 6, the walking track 6 is an i-shaped track, and two ends of the main beam 1 are respectively provided with a rail-gnawing prevention mechanism; the rail gnawing prevention device 4 comprises a bracket arranged at the end part of the main beam 1, and rollers 10 are arranged at the lower end of the bracket corresponding to the two sides of the upper wing plate of the I-shaped steel rail; the lateral part of support sets up cleaning plate 13, and cleaning plate 13's downside sets up cleans the brush.

The rail gnawing preventing crane is mainly used for factory workshops, and can effectively avoid rail gnawing in the operation process of the crane. Specifically, the idler wheels roll along the upper wing plates of the I-shaped steel rails in the traveling process of the cart, so that the cart traveling wheels can be effectively prevented from moving left and right to gnaw the rails. Meanwhile, the side part of the support is provided with the cleaning brush, so that sundries on the I-shaped steel rail can be cleaned in one step, and the crane can run more stably.

Further, a buffer 14 is arranged in the middle of the cleaning plate 13 so as to play a role of buffering when moving to the end of the running rail.

Furthermore, a sliding groove is formed in the middle of the roller 10, and the specification of the sliding groove is matched with the edge of the upper wing plate, so that the upper wing plate is clamped in the sliding groove of the roller in the rolling process.

Further, an upper mounting plate 11 and a lower mounting plate 12 are respectively arranged on two sides of the support, a rotating shaft is arranged between the upper mounting plate 11 and the lower mounting plate 12, and the roller 10 is arranged on the rotating shaft.

Further, the hanger comprises a lifting hook, a guide rod 8 connected with the lifting hook and a steel wire rope connected with the guide rod 8; a hanging bracket 3 is arranged above the main beam 1, and a derrick 2 is correspondingly arranged below the main beam 1; the upper end of the hanger 3 is provided with a pulley 9, and a steel wire rope is connected with a hoisting mechanism after being wound by the pulley 9; a plurality of groups of guide wheels 7 are arranged on the derrick 2 corresponding to the guide rod 8. In the hoisting process, the guide rod moves up and down along the guide wheel, cannot swing left and right, and is stable and higher.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
