[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] The gantry crane reducer disassembly device 100 according to the embodiment of the present invention comprises a vehicle body 1, a vehicle frame 2, a first telescopic device 3 and a second telescopic device 4. The vehicle frame 2 is arranged along a first direction (eg Figure 1 The first telescopic device 3 has a plurality of first telescopic devices, and the first telescopic device 3 is arranged on the vehicle body 1 so as to be movable in the second direction (for example, the left and right direction). Figure 1 The vehicle body 1 is driven to move in the up and down direction in the vertical direction) so that the frame 2 abuts against the reducer. One end of the second telescopic device 4 is arranged on the frame 2, and the second telescopic device 4 is telescoped along the first direction. The other end of the second telescopic device 4 is used to abut against the driving wheel group 200 of the gantry crane, so that the second telescopic device 4 drives the frame 2 to move in the first direction, and the first direction is perpendicular to the second direction.

[0030] When the gantry crane reducer disassembly device 100 according to the embodiment of the present invention is in use, the second direction is the same as the up and down direction, and the first direction is the horizontal direction, for example, the first direction is the same as the left and right direction.

[0031] When the active wheel group 200 of the gantry crane is being overhauled, the gantry crane reducer disassembly device 100 of the embodiment of the present invention is moved to the position to be overhauled through the car body 1, and then the position of the car body 1 is adjusted, and the frame 2 is moved to the position directly below the reducer 300, so that the second telescopic device 4 is directly opposite to the center of the axle 2001 of the active wheel group 200 in the first direction, and then the car body 1 is separated from the ground by extending the first telescopic device 3, so as to fix the car body 1, and the extension amount of the first telescopic device 3 is adjusted to ensure the horizontality of the car body 1 and the contact between the frame 2 and the bottom of the reducer 300, so that a certain extrusion pressure is formed between the reducer 300 and the frame 2, and then the second telescopic device 4 is operated to extend the second telescopic device 4, and then the frame 2 drives the reducer 300 to move in the direction away from the active wheel group 200 (in Figure 3 In the direction shown, it moves to the right), the reducer 300 which is pressed against the frame 2 moves synchronously with the frame 2, and the reducer 300 and the axle 2001 of the driving wheel set 200 are gradually separated.

[0032] When the reducer 300 is completely separated from the axle 2001, the reducer 300 is seated on the frame 2, and the disassembly of the reducer 300 is completed. Then, the reducer 300 can be moved to other locations through the disassembly device 100, thereby providing space for the maintenance of the driving wheel group 200, so that the maintenance can be carried out without disassembling the driving wheel group 200, thereby ensuring the maintenance efficiency of the gantry crane.

[0033] Therefore, the gantry crane reducer disassembly device 100 of the embodiment of the present invention is easy to use, can adapt to uneven ground, and can realize the disassembly of the reducer without disassembling the driving wheel group 200. The reducer can be disassembled and repaired, which solves the problem that the reducer of the gantry crane driving wheel group is difficult to disassemble and easily causes equipment damage, thereby ensuring the maintenance efficiency of the gantry crane.

[0034] In order to make the scheme of the present application easier to understand, the first direction is the same as the left-right direction, the second direction is the same as the up-down direction, and the third direction is the same as the front-back direction. The left-right direction is shown in the figure, the front-back direction is shown in the figure, and the up-down direction is shown in the figure.

[0035] The gantry crane reducer disassembly device 100 according to the embodiment of the present invention comprises a vehicle body 1, a vehicle frame 2, a first telescopic device 3 and a second telescopic device 4.

[0036] The vehicle body 1 includes a frame body 11, wheels 12 and a handle 13. The frame body 11 is a rectangular box-shaped base 21. Specifically, the frame body 11 is formed by welding plates. The frame body 11 is provided with a wheel 12 on one side (lower side) of the second direction, and the frame body 11 is provided with a frame 2 on the other side (upper side) of the second direction. The handle 13 is provided on the frame 2. The handle 13 is located on the right side of the frame body 11. The handle 13 can be used to push and pull the vehicle body 1 and turn the vehicle body 1.

[0037] The car body 1 has a simple structure and low cost, which can help reduce the cost of the gantry crane reducer disassembly device 100 according to the embodiment of the present invention.

[0038] There are multiple first telescopic devices 3, which are arranged on the frame body 11 of the vehicle body 1 so as to drive the vehicle body 1 to move in the second direction so that the frame 2 abuts against the reducer. Through the extension and retraction of the first telescopic devices 3, the vehicle body 1 can be raised, thereby achieving the purpose of fixing the vehicle body 1. At the same time, each first telescopic device 3 can also be fine-tuned to ensure that the frame body 11 is in a horizontal state, thereby ensuring the horizontality of the frame 2, ensuring the safety of the frame 2 supporting the reducer, and at the same time ensuring the horizontality of the frame 2 driving the reducer to move, thereby ensuring the smooth separation of the reducer from the wheel axle. In other words, multiple first telescopic devices 3 can enable the disassembly device 100 to adapt to working surfaces of different flatness.

[0039] Specifically, the first telescopic device 3 is a threaded screw elevator.

[0040] The frame 2 is movably disposed on the frame body 11 along the first direction, and the frame 2 is used to receive the reducer.

[0041] The vehicle frame 2 includes a base 21, a first side plate 22 and a seat plate 23. The base 21 is movably arranged on the vehicle body 1 along the first direction, and the base 21 is used to receive the reducer. The first side plate 22 is arranged on one side (right side) of the base 21 in the first direction. The seat plate 23 is arranged on the first side plate 22, and the seat plate 23 is connected to the second telescopic device 4, and the second telescopic device 4 faces the other side of the base 21 in the first direction.

[0042] The frame 2 is installed with the second telescopic device 4 through the first side plate 22 and the seat plate 23 located on the side of the base 21, so that a larger space is formed above the base 21, so that the reducer can be received, and the reducer can be received and the second telescopic device 4 can be abutted against the wheel axle 2001 at the same time.

[0043] When the disassembling device 100 is used, the frame 2 is moved to the position directly below the reducer, that is, the base 21 is moved to the position directly below the reducer.

[0044] Specifically, the vehicle body 1 is provided with a guide rail 111 extending in the first direction, and the vehicle frame 2 is provided with a roller 211, which is mounted on the guide rail 111. Specifically, the base 21 is provided with a roller 211. The cooperation between the roller 211 and the guide rail 111 forms a guide and limit for the movement of the base 21 in the first direction, ensuring that the vehicle frame 2 moves in the set direction and avoiding the deflection of the vehicle frame 2, so that when the second telescopic device 4 extends and drives the vehicle frame 2 to move rightward, the frame 2 is prevented from driving the reducer to deflect and causing wear and stagnation of the reducer and the axle 2001, ensuring the driving effect of the frame 2 on the reducer, and further ensuring that the reducer 300 is smoothly separated from the axle 2001, thereby improving the reliability of the operation of the gantry crane reducer disassembly device 100 according to the embodiment of the present invention.

[0045] In some embodiments, the frame 2 further includes a second side plate 24, which is disposed on the other side (left side) of the base 21 in the first direction, and is used to abut against a side of the reducer adjacent to the driving wheel set 200. Figure 3 As shown, the second side plate 24 abuts against the left side surface of the reducer 300 .

[0046] After the base 21 moves to the position directly below the reducer, the first side plate 22 and the seat plate 23 are installed, and then the second side plate 24 is installed on the base 21, and then the second telescopic device 4 is installed to ensure that the second telescopic device 4 is facing the axle 2001. When the second telescopic device 4 is extended, the base 21 is driven to move rightward, and the second side plate 24 is synchronously moved rightward. Since the second side plate 24 is in contact with the left side of the reducer, the second side plate 24 not only increases the contact area between the frame 2 and the reducer, but also forms a rightward thrust on the reducer, thereby facilitating the reduction gear to be removed from the axle 2001 of the active wheel set 200, thereby enhancing the driving effect of the frame 2 on the reducer, further ensuring the separation of the reducer from the axle 2001, and further improving the reliability of the operation of the gantry crane reducer disassembly device 100 of the embodiment of the present invention.

[0047] In some embodiments, there are two second side plates 24, the two second side plates 24 are spaced apart, and the two second side plates 24 are respectively located on both sides of the reducer in the third direction. Figure 2 As shown, the two second side plates 24 are respectively on the front and rear sides. The two second side plates 24 can make the front and rear sides of the reducer bear force evenly, so that when the second telescopic device 4 is extended to drive the base 21 to move to the right, the reducer is guaranteed to be subjected to force on both the front and rear sides of the axle 2001, so as to ensure that the reducer does not deflect relative to the axle 2001 when disengaging, thereby avoiding wear of the reducer and the axle 2001, further ensuring the smoothness of the separation of the reducer and the axle 2001, and further improving the reliability of the operation of the gantry crane reducer disassembly device 100 according to the embodiment of the present invention.

[0048] In some embodiments, the frame 2 further includes a connecting plate 25, which is located on the outer sides of the two second side plates 24. The second side plates 24 and the first side plates 22 are connected by the connecting plate 25, and the connecting plate 25 is perpendicular to the first side plates 22 and the second side plates 24. After the second side plates 24 are installed, the connecting plate 25 is installed. The second side plates 24 and the first side plates 22 are connected by the connecting plate 25, which increases the integrity of the first side plates 22 and the second side plates 24, increases the connection strength of the first side plates 22 and the second side plates 24, and also increases the stability of the first side plates 22 and the second side plates 24, thereby improving the strength of the frame 2, so that when the second telescopic device 4 is extended to drive the reducer to disengage, the stability of the frame 2 is further improved, ensuring the smoothness of the separation of the reducer and the wheel axle 2001, and further improving the reliability of the operation of the gantry crane reducer disassembly device 100 according to the embodiment of the present invention.

[0049] In some embodiments, there are two first side panels 22, the two first side panels 22 are spaced apart, the two first side panels 22 are connected to the seat plate 23, the two first side panels 22 are connected to the two second side panels 24 in a one-to-one correspondence, and the first side panels 22 and the second side panels 24 are both adjustably arranged on the base 21 along the third direction. Thus, the positions of the first side panels 22 and the second side panels 24 in the front-to-back direction of the base 21 can be adjusted, so that the space between the two second side panels 24 can be adjusted, so that when disassembling reducers of different sizes, the distance between the two second side panels 24 is adjusted to ensure that the two second side panels 24 fit the left side surface of the reducer 300, thereby improving the adaptability of the gantry crane reducer disassembly device 100 of the embodiment of the present invention to different gantry cranes.

[0050] In some embodiments, the second side plate 24 and the first side plate 22 are arranged with a plurality of connecting plates 25 in the second direction. Thus, the connection strength between the first side plate 22 and the second side plate 24 is further increased, the strength of the vehicle frame 2 is further improved, the stability of the vehicle frame 2 is further improved, the smoothness of the separation of the reducer and the axle 2001 is further ensured, and the reliability of the operation of the gantry crane reducer disassembly device 100 according to the embodiment of the present invention is further improved.

[0051] In some embodiments, the frame 2 further includes an L-shaped corner plate 26, an L-shaped corner plate 26 is provided between the connecting plate 25 and the first side plate 22, and an L-shaped corner plate 26 is provided between the connecting plate 25 and the second side plate 24. The L-shaped corner plate 26 facilitates the connection between the connecting plate 25 and the first side plate 22, and the installation operation between the connecting plate 25 and the second side plate 24, and increases the firmness of the installation connection, thereby further increasing the connection strength between the first side plate 22 and the second side plate 24, further improving the strength of the frame 2, further improving the stability of the frame 2, further ensuring the smoothness of the separation of the reducer and the wheel axle 2001, and further improving the reliability of the operation of the gantry crane reducer disassembly device 100 according to the embodiment of the present invention.
