[0027] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] Please see Figures 1-3 In this embodiment of the present invention, an auxiliary replacement device for a grab bucket ship unloader trolley towing order includes:

[0031] The crossbeam 1 has a first surface, which is defined as a mounting surface, and the crossbeam 1 is an angle iron.

[0032] Two lifting components are connected vertically along the first surface. The two lifting components are connected to a load-bearing component 4 that can move up and down with the lifting components. The load-bearing component 4 has a second surface, which is defined as a bearing surface. The second surface is used to contact the cable sliding mechanism and can drive the cable sliding mechanism to move vertically upward.

[0033] The positioning mechanism is formed on the first surface and includes a positioning element 5 and a movable element 6. The movable element 6 is connected to a locking element installed on the crossbeam 1. The positioning element 5 and the movable element 6 are used to engage and fix with the trolley drag track 11. Both the positioning element 5 and the movable element 6 are made of iron.

[0034] Adjust the lifting component to its longest length, and fix the crossbeam 1 to the trolley trailing track 11 using the positioning component 5 and the movable component 6 in conjunction with the locking component to ensure the stability of the connection between the crossbeam 1 and the trolley trailing track 11. Then connect both ends of the load-bearing component 4 to the two lifting components, and then adjust the lifting component to drive the load-bearing component 4 to move upward. After the load-bearing component 4 contacts the cable sliding mechanism, it continues to move upward, so that the cable sliding mechanism is disengaged from the trolley trailing track 11, thereby facilitating the maintenance or replacement of pulleys and other components on the cable sliding mechanism.

[0035] For details, please refer to Figure 4 and Figure 5 Taking the trolley track 11 as an I-beam as an example, the positioning member 5 is fixedly connected to the crossbeam 1, and the positioning member 5 is arranged in an L-shape, so that a slot for inserting one side of the I-beam is formed between the positioning member 5 and the crossbeam 1. The movable member 6 is movably arranged relative to the crossbeam 1, and the movable member 6 is arranged in a Z-shape. Another slot is also formed between the movable member 6 and the crossbeam 1 for inserting the other side of the I-beam. Since the movable member 6 is movably connected to the crossbeam 1, after the positioning member 5 is connected to the crossbeam 1, the position of the movable member 6 can be adjusted adaptively, and it can be connected with the locking member to the I-beam. It is highly flexible and can be adapted to I-beams of different specifications.

[0036] After the crossbeam 1 is fixed, the lifting component is controlled to move upward. After the load-bearing component 4 is released from the frame 55, the lifting component continues to move upward to drive the frame 55 and the track wheel frame 22 connected to the frame 55 to move upward. The track wheel 33 and the positioning horizontal wheel 44 on the track wheel frame 22 are disengaged from the I-beam. Then the track wheel 33 or the positioning horizontal wheel 44 can be repaired or replaced. After the replacement is completed, the lifting component is simply adjusted downward in the opposite direction to re-engage the track wheel 33 and the positioning horizontal wheel 44 with the I-beam.

[0037] This embodiment provides a lightweight and simple replacement device for replacing the track wheel 33 and positioning horizontal wheel 44 in the cable sliding mechanism of the trolley tow truck. Compared with traditional tool replacement, it is lighter, safer, more robust, and easier to carry and operate. After being fixed and lifted, the position of the crossbeam 1 does not change, and the lifting space is only appropriately expanded by the space occupied by the cable sliding mechanism. It can free up more working space than traditional tool lifting of the mechanism and has a wide range of applications.

[0038] Furthermore, a connecting ring 2 is fixed along the vertical direction of the first surface and connected to the lifting component. By connecting the lifting component with the connecting ring 2, the lifting component can be rotated relative to the connecting ring 2 when not in use, so that the lifting component is placed in a parallel position relative to the crossbeam 1, thereby reducing the space occupied by the device when not in use.

[0039] In one exemplary embodiment, the lifting component includes a turnbuckle 3. One end of the turnbuckle 3 is connected to the connecting ring 2, and the other end forms a hook that connects to the load-bearing component 4. Of course, the load-bearing component 4 has a hanging hole that can connect to the hook, which facilitates the quick assembly and disassembly of the load-bearing component 4 and the hook. The turnbuckle 3 described in this embodiment is a conventional technical module, so it will not be described in detail in this embodiment.

[0040] In one exemplary embodiment, the lifting component includes an electric telescopic rod. One end of the electric telescopic rod is fixed to the first surface of the crossbeam 1, and the other end has a hook for connecting to the load-bearing component 4. In this embodiment, the electric telescopic rod can also be replaced by a pneumatic cylinder or a hydraulic cylinder, which can be selected according to actual needs.

[0041] Of course, in the two embodiments described above, the lifting component is preferably made of turnbuckle 3.

[0042] The locking component described above includes a fixing bolt 7 that passes through the movable component 6. The fixing bolt 7 passes through the strip-shaped through groove 8 formed on the crossbeam 1 and is fixed by a nut. The fixing bolt 7 and the nut can fix the movable component 6 to the crossbeam 1. At the same time, the strip-shaped through groove 8 can easily adjust the distance between the movable component 6 and the positioning component 5 to meet the connection of I-beams of different specifications, and has a wide range of applications.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
