In order to achieve the purpose of the invention, the technical scheme of the utility model is as follows: the utility model provides a hoist horizontal leading wheel mounting structure, includes the end beam and sets up the leading wheel mechanism on the end beam, the tip of end beam is provided with the wheel, leading wheel mechanism sets up the end beam lower part in the inboard of wheel, leading wheel mechanism includes support frame, connecting axle and horizontal leading wheel, the support frame is fixed in the end beam lower part, the connecting axle is fixed on the support frame, the setting of horizontal leading wheel is tip under the connecting axle.

Furthermore, the support frame includes backup pad, upper fixed plate and bottom plate, and the backup pad is vertical to be fixed on the end beam inner wall, and upper and bottom plate fixes respectively at the middle part and the lower extreme of backup pad, and bottom plate and end beam bottom fixed connection.

Furthermore, a transverse groove is formed in the connecting shaft, a clamping plate is arranged in the groove, and the clamping plate is fixedly connected with the upper fixing plate through screws, so that the guide wheel mechanism is convenient to mount and dismount.

Furthermore, the corresponding positions of the upper fixing plate and the lower fixing plate are provided with mounting through holes, the connecting shaft is inserted in the mounting through holes, the lower end of the connecting shaft is provided with a shaft shoulder, and the horizontal guide wheel is connected with the connecting shaft through a bearing.

The utility model has the advantages that:

1. the utility model discloses a horizontal leading wheel mounting structure of hoist sets up the leading wheel mechanism in the inboard of wheel, has avoidd the leading wheel mechanism and has taken up end beam length, has shortened the length of end beam, has improved the walking distance of cart, improves the utilization ratio of factory building;

2. the installation structure of the horizontal guide wheel of the crane adopts the cylinder with the same diameter as the connecting shaft, thereby being convenient for the installation and the disassembly of the horizontal guide wheel;

3. the utility model discloses a horizontal leading wheel mounting structure of hoist, support frame are fixed with inside gusset and the web of end beam, and the structure is more stable, and impact resistance is strong.
