As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 4, the embodiment of the invention discloses a rail gnawing prevention device, which can be applied to a bridge crane, wherein the bridge crane is important equipment for realizing mechanization and automation of a production process in modern industrial production and hoisting transportation.
In the embodiment of the present invention, the anti-gnawing device includes a rolling part 100, the rolling part 100 includes a connecting shaft 110 and a roller 120, the roller 120 is rollably disposed on the connecting shaft 110, and specifically, the roller 120 is rotatable around the connecting shaft 110.
The bridge crane comprises a crane body 200 and wheels 300 arranged on the crane body 200 in a rolling manner, wherein the wheels 300 are provided with limiting grooves 310, and the limiting grooves 310 are matched with the tracks 400 in a rolling manner so as to ensure that the wheels 300 can roll on the tracks 400 more stably, thereby preventing the wheels 300 from derailing.
The rolling parts 100 are disposed on two opposite sides of the wheel 300, the rail 400 is disposed between the two rollers 120, and a distance between the rims of the two rollers 120 is smaller than a groove width of the limiting groove 310, specifically, a plane where the rail 400 contacts the limiting groove 310 may be a bearing surface, a projection of the distance between the rims of the two rollers 120 on the bearing surface may be a first projection, a projection of the groove width of the limiting groove 310 on the bearing surface may be a second projection, and the first projection is within the second projection. In this case, in a specific operation, when the wheel 300 is off tracking, the side wall of the limit groove 310 on the wheel 300 is firstly in rolling contact with the roller 120, thereby preventing the side wall of the limit groove 310 from contacting the rail 400.
It should be noted that the rotation axis of the roller 120 is perpendicular to the bearing surface, please refer to fig. 1 again, in the case that the wheel 300 is off tracking, it can be ensured that the bridge crane can drive the roller 120 to roll on the side wall of the track 400.
As can be seen from the above, in the embodiment of the disclosure, the rolling parts 100 are disposed on the two opposite sides of the wheel 300, so that the rail 400 can be located between the two rollers 120, when the wheel 300 deviates, the rail 400 firstly makes rolling contact with the rollers 120, and thus the side wall of the limiting groove 310 of the wheel 300 can be prevented from making sliding contact with the side wall of the rail 400, and the wheel 300 and the rail 400 are prevented from being worn away from each other. In this way, not only can the service lives of the wheels 300 and the rails 400 be prolonged, but also the running effect of the bridge crane can be improved. Moreover, the two rollers 120 can prevent the derailment of the wheel 300, thereby avoiding more serious consequences.
The rail gnawing prevention device disclosed by the embodiment of the invention can further comprise a support 500, and the support 500 can provide an installation position for the rolling part 100 so as to improve the installation effect of the rolling part 100. The bracket 500 may be disposed on the crane body 200, the bracket 500 may be fixed to the crane body 200 by welding, bonding, or screwing, or the like, and optionally, the bracket 500 may be fixed to the crane body 200 by bolts, thereby realizing detachability of the rail gnawing prevention device, and facilitating use of the rail gnawing prevention device; the rolling part 100 may be provided on the bracket 500, and particularly, the rolling part 100 may be fixed on the bracket 500 by a connecting shaft 110 to accomplish the assembly of the rolling part 100.

Further, the rolling part 100 may be mounted on the bracket 500 in various ways, and optionally, in order to facilitate mounting of the rolling part 100, the rolling part 100 may further include a nut 130, the bracket 500 may be provided with a connection table 510, the connection table 510 may be provided with a through hole 511, a first end of the connection shaft 110 may be provided with the roller 120, and a second end of the connection shaft 110 may pass through the through hole 511 and may be in threaded connection with the nut 130. This makes it easier to mount the rolling part 100 on the bracket 500, and also improves the mounting stability of the rolling part 100.
In order to further improve the installation stability of the rolling part 100, the rolling part 100 may further include an anti-slip gasket, the anti-slip gasket may be sleeved on the second end of the connection shaft 110, and the anti-slip gasket may be located between the nut 130 and the connection table 510. In this case, the anti-slip washer may improve the installation reliability of the nut 130 to prevent the tightened nut 130 from being loosened, thereby improving the installation stability of the rolling part 100 on the bracket 500. Of course, the anti-slip pad may be a metal pad or a non-metal pad, which is not limited in the embodiments of the present invention.
Accordingly, the rolling part 100 may further include a ferrule 140, the ferrule 140 may be sleeved on the first end of the connection shaft 110, and the ferrule 140 may be located between the roller 120 and the connection table 510. In this case, the ferrule 140 can keep the roller 120 away from the connecting table 510, so as to prevent the roller 120 from interfering with the connecting table 510 during the rolling process, so that the rolling effect of the roller 120 is better, and the operation effect of the bridge crane is better.
Alternatively, the through hole 511 may be an elongated hole, and an extending direction of the elongated hole may be perpendicular to the sidewall of the rail 400. In this case, in the process of installing the rolling part 100, the oblong hole can provide an installation margin for the connecting shaft 110, so that the roller 120 can move along the side wall close to or far away from the rail 400, the installation effect of the rolling part 100 is better, and the rolling part 100 can play a better rail gnawing prevention effect.
In an optional embodiment, the roller 120 may include a rolling element and a bearing, and in a specific installation process, an inner circle of the bearing may be sleeved on the connecting shaft 110, that is, the inner circle of the bearing may be fixed to the connecting shaft 110 by welding or bonding, and the rolling element may be sleeved on an outer circle of the bearing, that is, the rolling element may be fixed to the outer circle of the bearing by bonding or welding.
