[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0017] It should be noted that, in the description of the present invention, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0018] See attached Figure 1-3 The utility model proposes a traveling wheel replacement tool for a bucket wheel excavator, comprising a connecting bracket 1, a bearing I2, a shaft I3, a shaft sleeve 4, an upper connecting cover plate 5, an H-shaped steel 6, a shaft II7, a lateral connecting plate 8, a bearing II9 and a bearing base 10.

[0019] Among them, the upper connecting cover plate 5 is correspondingly arranged above the bearing base 10; the lateral connecting plates 8 are respectively fixedly welded between the upper connecting cover plate 5 and the left and right ends of the bearing base 10, and the upper connecting cover plate 5, the lateral connecting plate 8 and the bearing base 10 together form a tooling frame with front and back sides open.

[0020] The bearing I2 is vertically installed on the lower inner side of the upper connecting cover plate 5 through a horizontal axis I3. In this embodiment, shaft sleeves 4 are respectively installed on both sides of the shaft I; a through hole is opened in the middle of the bearing base 10; the bearing II9 is ​​respectively installed on both sides of the through hole in the middle of the bearing base 10 through a vertical axis II7; the H-shaped steel 6 is vertically arranged, and its top surface is rollingly pressed against the bearing I2, and its two sides of the web are respectively rollingly pressed against the bearings II9 on both sides; the connecting bracket 1 is an L-shaped frame, one end of which is fixedly connected to the top of the upper connecting cover plate 5, and the other end is fixedly connected to the running wheel frame of the bucket wheel excavator.

[0021] In this embodiment, the bearing I2 and the bearing II9 are both deep groove ball bearings.

[0022] The working principle of the utility model is as follows: during the replacement of the bucket wheel machine running wheel 11, the tooling is assembled in advance, the H-shaped steel 5 is fixed vertically to the ground, and then the tooling is installed in place, so that the upper bearing I2 is close to the top surface of the H-shaped steel 5, and the lower two side bearings II9 are respectively close to the two sides of the web of the H-shaped steel 5, and the gap between the bearing and the H-shaped steel 5 is adjusted to ensure that the tooling can slide freely on the H-shaped steel 5, and the end of the connecting bracket 1 of the tooling is fixedly connected to the running wheel frame by bolts, and then the connecting bolts between the running wheel frame and the steel structure are loosened, and after the steel structure is lifted up by the jack, the damaged running wheel is pulled out by a hand winch. Similarly, the new running wheel frame is pulled into place, the bolts are closed, and the jack is loosened to complete the replacement of the running wheel. The utility model can fix the running wheel during the replacement of the running wheel to prevent it from tipping over and other safety hazards. Moreover, since the running wheel is located below the steel structure of the bucket wheel machine, it is not convenient to hoist it. The utility model realizes the displacement of the running wheel through the cooperation of the bearing and the H-shaped steel 6, so that it can quickly slide out of the steel structure range, which is convenient for the replacement of the running wheel and can improve the replacement efficiency.

[0023] Matters not described in detail in this utility model are known technologies.

[0024] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
