[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0025] As described in the background technology, the tracks in the existing top operating system are all integrated, and the lifting tower can only be set at a specific position on the track. After the overhead crane fails, the overhead crane needs to be towed to the lifting tower by a traction device, which will affect the subsequent operation of the overhead crane, affect the workpiece transportation efficiency, and reduce work efficiency. How to move the overhead crane on the track to the lifting tower without affecting the operation of other overhead cranes is a technical problem that needs to be solved at present.

[0026] In order to solve this technical problem, the utility model provides a top transportation system which is convenient for overhead crane maintenance and is applied in the field of material transportation systems.

[0027] Specifically, please refer to Figure 1-3 The top transportation system for facilitating the maintenance of the overhead crane 2 specifically includes a top track 1, an overhead crane 2 and a maintenance lifting tower 3. The overhead crane 2 runs along the top track 1. At least one turning track 4 is provided on the top track 1. The maintenance lifting tower 3 is provided on one side of the turning track 4. The maintenance lifting tower 3 includes a tower body 5, a lifting track 6 and a lifting device 7. The lifting device 7 drives the lifting track 6 to rise and fall along the tower body 5. The turning track 4 can be docked with the lifting track 6 after changing direction.

[0028] The utility model provides a top transport system which is convenient for the maintenance of the overhead crane 2. By arranging a deflection track 4 on the top track 1, when the overhead crane 2 is abnormal or damaged, the overhead crane 2 is dragged to the nearby deflection track 4, and the deflection track 4 is docked with the lifting track 6 after being changed in direction, so that the abnormal or damaged overhead crane 2 is pushed to the lifting track 6, and the lifting track 6 is lowered from the top to the bottom by the lifting device 7, so that the overhead crane 2 is pushed out for maintenance, and the abnormal overhead crane 2 can be quickly taken out from the top track 1, reducing the impact on the subsequent operation of the overhead crane 2. The abnormal or damaged overhead crane 2 does not need to be repaired at high altitude, thus avoiding high-altitude operations, which is beneficial to personnel safety, saves time, and improves work efficiency.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] Please refer to Figure 1-3 , a top transport system for facilitating the maintenance of an overhead crane 2 is provided, which includes a top track 1, an overhead crane 2 and a maintenance lifting tower 3. The overhead crane 2 is powered by a driving mechanism so that the overhead crane 2 runs along the top track 1. The top track 1 is provided with at least one turning track 4, and the turning track 4 is in a straight line shape. The maintenance lifting tower 3 is provided on one side of the turning track 4. The maintenance lifting tower 3 includes a tower body 5, a lifting track 6 and a lifting device 7. The lifting device 7 drives the lifting track 6 to rise and fall along the tower body 5. The turning track 4 can dock with the lifting track 6 after changing direction. When the lifting track 6 lowers the abnormal overhead crane 2 to the bottom, the overhead crane 2 moves from the lifting track 6 to the carrier 8. Specifically, the carrier 8 is provided with a carrier track 9. After the lifting track 6 is lowered, the carrier track 9 docks with the lifting track 6. The carrier 8 is used to transport the overhead crane 2 to the maintenance point.

[0033] According to the length of the ring of the top track 1, multiple turning tracks 4 can be set, and the interval between two adjacent turning tracks 4 is 10-15m. In order to reduce the construction of the maintenance lifting tower 3, the turning tracks 4 are symmetrically arranged, and the maintenance lifting tower 3 is arranged between the two turning tracks 4. Therefore, after the top track 1 of the overhead crane 2 on any section is abnormal or damaged, the overhead crane 2 can move from the nearest turning track 4 to the lifting track 6 of the maintenance lifting tower 3, so as to lower the overhead crane 2 to the ground, and the abnormal or damaged overhead crane 2 can be removed from the top track 1 as quickly as possible, ensuring the normal operation of the subsequent normal overhead crane 2, thereby improving production efficiency.

[0034] An electric bolt 16 is provided at the end of the changing track 4, and a socket 17 matching the electric bolt 16 is provided on the top track 1 and the lifting track 6. After the changing track 4 is docked with the top track 1 or the lifting track 6, the pin rod of the electric bolt 16 is inserted into the socket 17, thereby ensuring the stability of the changing track 4 when docking.

[0035] The top transport system also includes other structures, such as an electrical control system, a lifting mechanism, an operating mechanism for filling operation, etc. These parts are existing structures and will not be described separately here.

[0036] The top transport system for facilitating the maintenance of the overhead crane 2 provided in Example 1 is further optimized. Specifically, Figure 2As shown, the direction-changing track 4 is rotatably arranged and each rotation angle of the direction-changing track 4 is 90°. Specifically, the direction-changing track 4 is installed on a rotating structure 10, and the rotating structure 10 is used to drive the direction-changing track 4 to rotate, so that the direction-changing track 4 is docked with the lifting track 6.

[0037] The rotating structure 10 includes a base 11, a rotating table 12 and a driving device 13. The rotating table 12 is rotatably installed on the base 11 and the driving device 13 drives the rotating table 12 to rotate. The changing track 4 is fixed on the rotating table 12. The driving device 13 is a servo motor. The driving device 13 can drive the rotating table 12 to rotate on the base 11, and then drive the changing track 4 on the rotating table 12 to rotate.

[0038] A bottom frame 14 is provided below the base 11, on which a plurality of groups of hydraulic cylinders 15 are installed, which are fixedly connected to the base 11 and drive the base 11 to rise and fall. When the turning track 4 needs to rotate, the hydraulic cylinder 15 drives the base 11 to descend or rise, so that there is a height difference between the turning track 4 and the top track 1 or the lifting track 6, thereby avoiding collision between the turning track 4 and the top track 1 or the lifting track 6 when the turning track 4 rotates.

[0039] The top transport system for facilitating maintenance of the overhead crane 2 provided in Example 2 is further optimized. Specifically, Figure 4 As shown, the turning track 4 adopts a cross-shaped structure. After the turning track 4 rotates, one direction of the turning track 4 docks with the lifting track 6, and the other direction of the turning track 4 docks with the top track 1. After the overhead crane 2 travels to the cross-shaped turning track 4, when the overhead crane 2 changes lanes, it will not affect the subsequent overhead crane 2, thereby ensuring the normal operation of the overhead crane 2.

[0040] The working principle of the top transportation system for facilitating the maintenance of the overhead crane 2 provided by the utility model is as follows: the overhead crane 2 runs on the top track 1, and a turning track 4 is arranged on the top track 1. After the overhead crane 2 becomes abnormal or damaged, the overhead crane 2 is dragged to the nearby turning track 4, and the turning track 4 is docked with the lifting track 6 after changing direction, and the abnormal or damaged overhead crane 2 is pushed to the lifting track 6, and the lifting track 6 is lowered from the top to the bottom by using the lifting device 7, so that the overhead crane 2 can be pushed out for maintenance, and the abnormal overhead crane 2 can be quickly taken out from the top track 1, reducing the impact on the subsequent operation of the overhead crane 2. The abnormal or damaged overhead crane 2 does not need to be repaired at high altitude, thus avoiding high-altitude operations, which is beneficial to personnel safety, saves time, and improves work efficiency.
