[0019] The utility model will be described in detail below in combination with the drawings of the specification, but it should be pointed out that the implementation of the utility model is not limited to the following embodiments.

[0020] Embodiment 1

[0021] See Figures 1-2 A crane wheel replacement auxiliary tool, comprising a transverse guide rail 1, a slidable trolley 2 and a support base 3, the transverse guide rail 1 is provided with a bayonet 8 at one end bottom, and the other end bottom is fixedly connected with the support base 3, the transverse guide rail 1 is provided with a sliding channel, and the slidable trolley 2 is slidably connected with the transverse guide rail 1; the slidable trolley 2 is provided with an opening 10 matched with the width of the wheel at the upper part, and is provided with a sliding block 7 at the lower part. The transverse guide rail 1 comprises channel steel and connection rib 6, two channel steels are arranged in parallel with each other, and a plurality of connection ribs 6 are welded between the two channel steels and arranged in parallel with each other. The bayonet 8 is matched with the shape of the upper part of the wheel track 5. The bayonet 8 is a character-shaped structure.

[0022] When replacing the wheel, the transverse guide rail 1 is lapped on the wheel track 5 through the clamping hole 8 thereon and is supported and fixed through the supporting base 3, keeping the transverse guide rail 1 in a horizontal position. The slidable trolley 2 is placed on the slide, and the sliding block 7 is placed inside the slide to prevent the slidable trolley 2 from deviating from the slide when moving. The removed wheel is pushed onto the slidable trolley 2 through the opening 10 on the slidable trolley 2. The end of the crowbar 4 is clamped on the connecting rib 6, the slidable trolley 2 is lapped on the crowbar 4, and the end of the crowbar 4 is held by the worker. Under the action of the lever force, the slidable trolley 2 is moved outward along the transverse guide rail 1 little by little until the wheel is separated from the lower part of the crane body and reaches the position capable of being hoisted by the vertical hoisting equipment. Then the wheel can be hoisted away by the vertical hoisting equipment. When installing the wheel, the above steps are operated in reverse. First, the new wheel is hoisted onto the slidable trolley 2 by the vertical hoisting equipment, and then the slidable trolley 2 is moved by the crowbar 4 until the wheel is aligned with the wheel track 5, the wheel is fixed, and the wheel installation is completed.

[0023] Example 2

[0024] See Figures 1-4 The difference from example 1 is that the slidable trolley 2 is connected with a supporting frame for preventing the wheel from moving on the slidable trolley 2. The supporting frame comprises a base 11, a supporting rod 12 and a limiting rod 13. The base 11 is connected with the slidable trolley 2 through bolts or pins 9, two supporting rods 12 are fixedly connected on the base 11, and the limiting rod 13 is fixedly connected between the two supporting rods 12. The supporting frame can be multiple and can be arranged around the slidable trolley 2. Before the wheel is placed on the slidable trolley 2, a supporting frame is installed on the slidable trolley 2 and the base 11 is fixed by bolts or pins 9. The removed wheel is pushed onto the slidable trolley 2 through the opening 10 on the slidable trolley 2, and the wheel is prevented from rolling off the slidable trolley 2 by the supporting frame. Then the other three supporting frames are installed to enclose the wheel in the four supporting frames, so that the wheel will not move or fall during the translation of the slidable trolley 2 by the crowbar 4, achieving the purpose of safely moving the wheel and eliminating potential dangers.

[0025] The utility model discloses simple and reasonable structure, easy to assemble, convenient on -the -spot use, improved the work efficiency of bridge crane replacement single wheel. Transverse guide rail 1 is lapped on the wheel track 5 through the clamping hole 8 thereon and is supported and fixed through the supporting base 3, and the wheel is carried by slidable trolley 2, and then the slidable trolley 2 is moved on the transverse guide rail 1 by crowbar 4, and then the wheel is moved out of the lower part of the crane body, and the vertical hoisting equipment is used to hoist the wheel, and the utility model has the advantages of simple use, shortened operation time and improved vertical hoisting equipment utilization.
