In the preferred embodiment, the fixing plate portion 32 is disposed at one end of the seat plate portion 31, so that the base 30 forms an L-shaped seat. The fixing plate portion 32 is provided with a plurality of fixing holes 321 , and the seat plate portion 31 is provided with two sets of connecting holes 311 .

As shown in FIG. 1 to FIG. 4 , the two guide positive wheel sets 40 are assembled on the base 30 and can be arranged on opposite sides of the crown rail 2 . As shown in FIG. 1 , FIG. 2 and FIG. 4 , in the preferred embodiment, the two guide wheel sets 40 each include an axle assembly 41 and a guide wheel 42 . The axle of the two guide wheel set 40 The components 41 are respectively disposed on the base 30, and the guide wheel 42 is connected to the lower end of the axle assembly 41. The two guide positive wheels 42 are located on opposite sides of the crown rail 2 . In the preferred embodiment, the guide wheel 42 includes a wheel body 421 and a bearing 422 disposed in the wheel body 421. The wheel axle assembly 41 includes an axle 411, a sleeve 412, and a nut 413. The axle 411 The bottom end is assembled in the bearing 422 of the guide wheel 42. The upper end of the axle 411 has a threaded section. The sleeve 412 is sleeved on the outer side of the axle 411. The threaded section of the upper end of the axle 411 is disposed through the assembly hole 311 of the base 30. The nut 412 is locked by a nut 413, and the sleeve 412 is located between the bottom surface of the seat plate portion 31 of the base 30 and the bearing 422 of the guide wheel 42. A corresponding through hole may be disposed between the axle 411 and the nut 413, and the pin is fixed to the corresponding hole of the wheel shaft 411 and the nut 413 to prevent the nut 413 from being loosened from the axle 411.

As shown in FIG. 1 to FIG. 4, in the preferred embodiment, the crane moving guide auxiliary device further includes a fixing plate 50, so that the base 30 is fixed to the fixed plate of the crane by the fixing plate 50. The 50 series is used for welding and fixing to the saddle 10 of the crane 1. The fixing plate 50 is provided with a plurality of screw holes, so that the base 30 can be locked and fixed by the plurality of bolts respectively passing through the fixing holes 321 of the base 30. In the screw hole of the plate 50.

As shown in FIG. 3 and FIG. 4, when the crane moving guide auxiliary device 3 is applied to the crane 1, the base 30 is bolted to the saddle 10 of the crane 1 and is located on the overhead rail 2 The guide rollers 42 of the two guide wheel sets 40 disposed on the base 30 are arranged opposite to each other on the two sides of the crown rail 2, that is, the guide wheels 42 of the two guide wheel sets 40 are close to each other or Contact the side of the crane rail 2. Thus, when the vehicle is driven, the driving wheel and the driven wheel 11 at the bottom of the saddle 10 of the crown block 1 are moved along the crown rail 2, and the two guide wheels 42 are guided on opposite sides of the crown rail 2 Positively, the offset of the driving wheel or the driven wheel 11 at the bottom of the crown block 1 with respect to the crown rail 2 is reduced, thereby improving the side wear of the driving wheel or the driven wheel 11 of the crown block 1.
