[0036] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figure 1 and Figure 4 As shown, the cable crane trolley wheel maintenance device of this utility model embodiment includes a frame 1, a support frame 2, a top support assembly 3, and a fall arrestor assembly 4. The frame 1 includes a base frame 11, a top frame 12, and a vertical pole for connecting the base frame 11 and the top frame 12. The height direction of the frame 1 is defined as the vertical direction. The support frame 2 is located on the base frame 11. The side of the support frame 2 near the top frame 12 restricts a support platform for supporting the wheel body 5. The top support assembly 3 is located on the top frame 12 corresponding to the support frame 2. The top support assembly 3 includes a top support part 31 whose position is adjustable in the vertical direction. The top support part 31 is used to press against the wheel bearing 6. The fall arrestor assembly 4 includes a traction rope 41 and a fall arrestor plate 42. The two ends of the traction rope 41 are connected to the top frame 12 and the fall arrestor plate 42, respectively. The traction rope is used to pass through the inner wheel sleeve 7. The fall arrestor plate 42 is used to stop the inner wheel sleeve 7 in the vertical direction.

[0038] In use, the cable crane trolley wheel maintenance device of this utility model places the wheel on the support platform to support the wheel body 5 through the support frame 2. At the same time, the traction rope 41 passes through the inner spacer 7 of the wheel, so that the two ends of the traction rope 41 are connected to the top frame 12 and the anti-fall plate 42 respectively. The top support part 31 in the top support assembly 3 moves in the vertical direction to support the wheel bearing 6 to separate from the wheel body 5. When the wheel bearing 6 is separated from the wheel body 5, the wheel bearing 6 is still connected to the inner spacer. The anti-fall plate 42 supports the wheel bearing 6 under the inner spacer, preventing the wheel bearing 6 and the inner spacer from falling freely and being damaged. At the same time, it prevents the wheel bearing 6 and the inner spacer from falling freely and causing damage to the maintenance device and injury to the operators.

[0039] The cable crane trolley wheel maintenance device of this utility model realizes the separation of wheel body 5 and inner spacer through top support component 3 and support frame 2. It is easy to operate and the maintenance device has a simple structure, which is easy to assemble on the construction site. It realizes maintenance work on the construction site, which facilitates timely disassembly, replacement and assembly of damaged wheels, and shortens the construction period impact caused by wheel device replacement.

[0040] Optionally, the diameter of the inscribed circle of the anti-fall disc is not less than the outer diameter of the inner spacer 7 of the wheel.

[0041] In some embodiments, such as Figure 2 and Figure 3As shown, it includes a top-impact member 8, which includes a top-impact circular plate 81 and a connecting plate 82. The connecting plate 82 is used to pass through the inner sleeve 7 of the wheel, and the top-impact circular plate 81 is used to stop and cooperate with the inner sleeve 7 of the wheel. The end of the connecting plate 82 opposite to the top-impact circular plate 81 is provided with a connecting part 821, which is used to lift the top-impact member 8.

[0042] Specifically, the impact member 8 includes an impact circular plate 81 and a connecting plate 82 disposed perpendicular to the impact circular plate 81. The diameter of the impact circular plate 81 is larger than the inner diameter of the inner wheel spacer 7 and smaller than the outer diameter of the inner wheel spacer 7. A connecting part 821 is provided at one end of the connecting plate 82 away from the impact circular plate 81. The connecting part 821 can be a connecting hole provided on the connecting plate 82, or a connecting ring or connecting lug provided on the connecting plate 82.

[0043] In use, the connecting plate 82 passes through the inner wheel sleeve 7, and the impact plate 81 stops the inner wheel sleeve 7, thus supporting the inner wheel sleeve 7. The connecting part 821 raises the impact member 8, the inner wheel sleeve 7, and the wheel bearing 6 mated on the inner wheel sleeve 7 to a set height. Then, the impact member 8 is released, causing the impact member 8, the inner wheel sleeve 7, and the wheel bearing 6 mated on the inner wheel sleeve 7 to fall freely. When the impact member 8 contacts the ground or a support, the inner wheel sleeve 7 impacts the top support plate, thus transmitting the impact force to the position of the wheel bearing 6. This causes the relative displacement of the wheel bearing 6 and the inner wheel sleeve 7 to separate the wheel bearing 6 and the inner wheel sleeve 7. The operation is convenient and reliable, and it is easy to separate and replace the wheel bearing 6.

[0044] In some embodiments, the top impact member 8 includes a positioning member 83 disposed on the top impact member 8, the positioning member 83 being used to cooperate with the inner wheel sleeve 7 to fix the relative position of the top support disc and the inner wheel sleeve 7.

[0045] Specifically, such as Figure 2 and Figure 3 As shown, the positioning component 83 is a positioning plate, which is vertically and symmetrically arranged on both sides of the connecting plate 82. The positioning plate is fixedly connected to the impact circular plate 81. A guide portion is provided on the side of the positioning plate away from the impact circular plate 81. The length of the guide portion in the direction perpendicular to the connecting plate 82 decreases in the direction away from the impact circular plate 81. When the connecting plate 82 is fitted with the inner wheel spacer 7, the side of the positioning plate away from the connecting plate 82 presses against the inner surface of the inner wheel spacer 7, thereby realizing the positioning and fixing of the inner wheel spacer 7 by the positioning plate. It should be noted that one or more positioning plates can be provided on one side of the connecting plate 82 to ensure the positioning and fixing of the inner wheel spacer 7.

[0046] Alternatively, the positioning element 83 is a positioning block. The positioning block is located on the circumference of the impact plate 81, and the positioning block and the connecting plate 82 are located on the same side of the impact plate 81. The side of the positioning block away from the axis of the impact plate is provided with a positioning arc surface. The diameter of the cylinder corresponding to the positioning arc surface is not greater than the inner diameter of the inner spacer 7 of the wheel. The maximum distance from the positioning arc surface to the axis of the impact plate is equal to the inner diameter of the inner spacer 7 of the wheel. When the connecting plate 82 is inserted into the inner spacer 7 of the wheel, the positioning arc surface abuts against the inner spacer 7 of the wheel to position the inner spacer 7 of the wheel.

[0047] Alternatively, the positioning element 83 is a positioning cone, which is coaxially mounted on the impact plate 81 and has a through hole for the connecting plate 82 to pass through. The outer diameter of the positioning cone decreases in the direction away from the impact plate, and the diameter of the end of the positioning cone connected to the impact plate 81 is equal to the diameter of the inner wheel sleeve 7. When the connecting plate 82 is inserted into the inner wheel sleeve 7, the outer side of the positioning cone guides the insertion and the end of the positioning cone connected to the impact plate 81 abuts against the inner wheel sleeve 7 to position the inner wheel sleeve 7.

[0048] In some embodiments, such as Figure 1 and Figure 4 As shown, the support frame 2 includes a support plate 21. Multiple support plates 21 are provided and spaced apart circumferentially. The top frame 12 of the multiple support plates 21 together restricts the support platform. The support plates 21 are provided to support the wheel body 5. At the same time, the multiple support plates 21 spaced apart circumferentially restrict the disassembly cavity to accommodate the anti-fall plate 42 and the disassembled wheel bearing 6 and wheel inner spacer 7, which facilitates disassembly.

[0049] Optionally, the support plate 21 may have two, three, or four.

[0050] Optionally, the support plate 21 is an arc-shaped plate.

[0051] In some embodiments, such as Figure 4 As shown, the support frame 2 includes a connector 22. Multiple connectors 22 are provided, and the multiple connectors 22 are respectively provided between two adjacent support plates 21. By providing connectors 22, the connection strength between two adjacent support plates 21 can be increased, further ensuring the stability of the support plates 21 during operation.

[0052] In some embodiments, such as Figure 4 As shown, the support frame 2 includes a guide ring 23 disposed on the support plate 21. The guide ring 23 is tapered and its diameter increases in the direction away from the support plate 21. The axis of the guide ring 23 coincides with the axis of the cylinder formed by the plurality of support plates 21.

[0053] Specifically, the guide ring 23 is set on the top of the support plate 21. By aligning the axis of the guide ring 23 with the axis of the cylinder formed by the multiple support plates 21, the wheel body 5 can be placed on the support platform to guide the placement of the wheel body 5, ensuring that the wheel body 5 is directly supported on the support plate 21, which facilitates the separation of the wheel bearing 6 and the wheel body 5, making the operation convenient.

[0054] In some embodiments, such as Figure 1 and Figure 4 As shown, the top support assembly 3 includes multiple hydraulic jacks 32, one end of which is connected to the top frame 12, and the top support part 31 is located at the other end of the hydraulic jack 32.

[0055] By setting up a hydraulic jacking machine 32, a jacking force is applied to the wheel bearing 6 when separating it, which is convenient and reliable to operate. At the same time, the jacking support 31 adopts a jacking plate to ensure the foundation area with the wheel bearing 6.

[0056] In some embodiments, such as Figure 4 As shown, the fall arrestor assembly 4 includes a lifting unit 43, one end of a traction rope 41 is connected to the lifting unit 43, and the lifting unit 43 is used to tighten or release the traction rope 41 to adjust the height of the fall arrestor plate 42.

[0057] By setting up the lifting unit 43, when the top support part 31 in the top support assembly 3 moves in the vertical direction to support the separation of the wheel bearing 6 from the wheel body 5, the traction rope 41 can be released according to the separation size of the wheel bearing 6, thereby maintaining the distance between the fall arresting plate 42 and the wheel bearing 6, so as to reduce the impact on the fall arresting plate 42 after the wheel bearing 6 separates.

[0058] Optionally, the lifting unit 43 is a hand chain hoist or a winch. If the lifting unit 43 is a winch, the top frame 12 is equipped with a mobile power supply that is electrically connected to the winch.

[0059] In some embodiments, such as Figure 4 As shown, a roller 13 is provided below the base frame 11, and a brake assembly is provided on the roller 13. By setting the roller 13, it is easy to move the device, making it more convenient to use. The brake assembly can also fix the position of the base frame 11 to ensure stability during use.
