Technical Field
[0001] This utility model relates to the field of gantry crane technology, and in particular to a novel gantry crane maintenance device. Background Technology
[0002] In daily work, when repairing large horizontal centrifugal pumps that handle acidic fluids, a situation may arise where the impeller is stuck due to media leakage and is difficult to disassemble. The conventional solution is to pry the impeller at a 180° angle on both sides with a long pry bar, or to cut it along with the shaft.
[0003] The gantry maintenance device mainly consists of a main support, hanging plates, U-shaped plates, and steel wire ropes. In use, the main support and hanging plates are connected by steel wire ropes. The length of the steel wire ropes can be adjusted according to different equipment heights. The hanging plates and U-shaped plates are connected by long bolts, the length of which is often determined by the length of the jacks. The U-shaped plates have front and back sides; the back is flat and can be inserted into the gap between the impeller and the pump body in an inverted U-shape. The front has reinforcing ribs to ensure the overall strength of the U-shaped plates. The pump shaft is connected to the hanging plates by jacks. By adjusting the distance between the overall support and the pump shaft, the gantry device is assembled. Then, by applying force to the jacks, the impeller receives a uniform outward pulling force, thus enabling impeller disassembly.
[0004] The gantry frame device in the above-mentioned prior art uses different types of long bolts to adjust the distance between the hanging plate and the template. Although this adjustment method is relatively convenient, each time the long bolts are replaced, it is necessary to first unscrew the two sets of long bolts in sequence, and then screw in the replaced long bolts for installation, which makes the use of the gantry frame device inconvenient.

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example: Figures 1-7 As shown, a novel maintenance gantry device includes: a support 1, a steel wire rope 11 sleeved at the lower end of the support 1, and a hanging plate 12 sleeved at the lower end of the steel wire rope 11. A U-shaped plate 13 is provided at one end of the hanging plate 12, and a rotating component 2 is provided at the end of the hanging plate 12 near the U-shaped plate 13. The rotating component 2 includes a protective cover 21 provided at the end of the hanging plate 12 near the U-shaped plate 13, and a first twisting plate 22 is provided on the upper side of the end of the protective cover 21 near the hanging plate 12.

An adjustment component 4 is provided at the end of the transmission component 3 away from the first gear 23, and a locking component 5 is provided at the end of the adjustment component 4 away from the transmission component 3. A locking component 6 is provided at the lower end of the locking component 5, and a limiting component 7 is provided at both ends of the locking component 6.
[0017] like Figure 3 As shown, the transmission assembly 3 includes a first gear 23 with a second gear 31 meshing with the outer gears at both ends, and a rotating rod 32 is fixedly connected to the end of the second gear 31 away from the first gear 23. The end of the rotating rod 32 away from the second gear 31 is rotatably connected to the cover 21, and a third gear 33 is fixedly connected to the outer side of the end of the rotating rod 32 away from the second gear 31.
[0018] like Figure 4 As shown, the adjusting assembly 4 includes a fourth gear 41 that meshes with the outer gear of the third gear 33, and an internally threaded cylinder 42 is fixedly connected to the end of the fourth gear 41 away from the third gear 33. The outer side of the internally threaded cylinder 42 is rotatably connected inside the protective cover 21, and a first threaded rod 43 is internally threaded at the end of the internally threaded cylinder 42 away from the fourth gear 41.
[0019] like Figure 4 and Figure 7 As shown, the snap-fit assembly 5 includes a first insert plate 51 fixedly connected to the end of the first threaded rod 43 away from the inner threaded cylinder 42 and the end of the protective cover 21 near the hanging plate 12. A snap-fit plate 52 is sleeved on the outer side of the end of the first insert plate 51 away from the protective cover 21 and the first threaded rod 43. The end of the snap-fit plate 52 away from the first insert plate 51 is fixedly connected to the hanging plate 12 and the U-shaped plate 13 respectively.
[0020] like Figure 5 As shown, the locking assembly 6 includes a connecting rod 61 disposed at the lower end of the second insert plate 53, and a second threaded rod 62 with internal threads engaged at both ends of the connecting rod 61. A second screw plate 63 is fixedly connected to one end of the second threaded rod 62 away from the connecting rod 61, and a third threaded rod 64 is fixedly connected to one end of the second screw plate 63 away from the second threaded rod 62. The third threaded rod 64 is threadedly engaged in the second insert plate 53 at one end away from the second screw plate 63.
[0021] like Figure 6 As shown, the limiting component 7 includes connecting plates 71 fixedly connected to the outer sides of both ends of the connecting rod 61, and a top plate 72 fixedly connected to the end of the connecting plate 71 away from the connecting rod 61, with the upper side of the top plate 72 fitting against the lower side of the card plate 52.
[0022] like Figure 7 As shown, a second insert plate 53 is inserted inside the first insert plate 51 and the card plate 52, and a pull ball 54 is fixedly connected to the upper end of the second insert plate 53.
[0023] When adjusting the distance between the hanging plate 12 and the U-shaped plate 13, the first screw plate 22 is turned under the support of the cover 21. After the first screw plate 22 is turned, it drives the first gear 23 to rotate.
[0024] After the first gear 23 rotates, it meshes with the second gear 31, driving the second gear 31 and the rotating rod 32 to rotate. After the rotating rod 32 rotates, it synchronously drives the third gear 33 to rotate.
[0025] After the third gear 33 rotates, it meshes with the fourth gear 41, causing the fourth gear 41 and the internal threaded cylinder 42 to rotate. After the internal threaded cylinder 42 rotates, it meshes with the first threaded rod 43, causing the first threaded rod 43 to push the first insert plate 51 and others to move, thereby causing the first insert plate 51 and the clamping plate 52 to move and adjust the U-shaped plate 13.
[0026] When replacing the protective cover 21, first turn the second screw plates 63 at both ends of the connecting rod 61. After the second screw plates 63 are turned, they drive the second threaded rod 62 and the third threaded rod 64 to rotate. This allows the third threaded rod 64 to unscrew the second insert plate 53 by engaging with the threads of the second threaded rod 62 and the third threaded rod 64 and the connecting rod 61. Then, pull the pull ball 54 to pull out the first insert plate 51 and the retaining plate 52. Then, pull the protective cover 21 to pull out the retaining plates 52 on both sides for removal. During subsequent installation, the first... Insert plate 51 is inserted into clamping plate 52. Then, pull ball 54 drives second insert plate 53 to be inserted into first insert plate 51 and clamping plate 52. Then, turn the second screw plate 63 at both ends to drive second threaded rod 62 and third threaded rod 64 to rotate. The third threaded rod 64 is screwed into second insert plate 53 by the thread engagement of second threaded rod 62 and third threaded rod 64 with second insert plate 53 and connecting rod 61, thereby locking and restricting the second insert plate 53. The connecting plate 71 and top plate 72 are used to lock and restrict the lower side of connecting rod 61 and first insert plate 51.
