Description

Technical Field

[0001] The utility model relates to the technical field of generator disassembly and assembly, in particular to an auxiliary disassembly tool. Background Art

[0002] Generator maintenance is a complicated process, and removing the generator upper cover is one of the steps. In the design of the generator, the upper cover is usually not equipped with a screw hole to prevent foreign matter from entering the generator. Therefore, the way to remove the generator is to directly lift the upper cover with an overhead crane to separate it.

[0003] However, due to the requirement for the sealing of the generator, users often fill the gap between the upper cover and the casing with sealant, and the adhesive force of the sealant makes it difficult to separate the upper cover from the casing. When the lifting force is greater than the weight of the upper cover during overhead crane lifting, the upper cover does not move at all. When the lifting force is further increased to eliminate the adhesive force between the upper cover and the casing so that the upper cover is separated from the casing, the upper cover will suddenly bounce up because the lifting force is much greater than the gravity of the upper cover, posing a great hidden danger to personal safety and equipment safety.

[0027] Please refer to Figure 1 , Figure 2 as well as Figure 3In order to solve the potential safety hazard of disassembling the upper end cover a1 of the generator a, the utility model proposes an auxiliary disassembly tool 1000 for assisting in disassembling the upper end cover a1 of the generator a. The auxiliary disassembly tool 1000 includes:

[0028] In the technical solution of the utility model, the auxiliary disassembly tool 1000 includes a clamping part 1, a locking piece 4 and a load-bearing part 2, the clamping part 1 is formed with a clamping groove 11, the clamping groove 11 is used to clamp with the reinforcing rib a11 of the upper end cover a1, and the clamping part 1 is used to abut and limit with the outer wall of the upper end cover a1 located on the periphery of the reinforcing rib a11; a locking hole 12 is formed on the groove wall of the clamping groove 11, and the locking hole 12 passes through the clamping part 1; the locking piece 4 passes through the locking hole 12 and extends into the clamping groove 11; the locking piece 4 is used to realize the fixation of the clamping part 1 and the reinforcing rib a11; the load-bearing part 2 is connected to the clamping part 1, and when the clamping part 1 is clamped with the reinforcing rib a11 of the upper end cover a1, the load-bearing part 2 can protrude from the edge of the upper end cover a1. The clamping part 1 locks the reinforcing rib a11 through the locking piece 4 through the locking hole 12, and then applies a force to the load-bearing part 2 to keep it away from the casing a2 of the generator a; and the load-bearing part 2 is connected to the clamping part 1, and the clamping part 1 locks the reinforcing rib a11, so a certain gap will be pushed out between the casing a2 and the upper end cover a1.

[0029] In the technical solution of the present utility model, a gap is pushed out between the casing a2 and the upper end cover a1, and the above-mentioned operation is performed on the reinforcing rib a11 of the upper end cover a1, which can eliminate most of the adhesion between the casing a2 and the upper end cover a1; in this way, when the upper end cover a1 is lifted by the overhead crane, the lifting force will not far exceed the weight of the upper end cover a1, thereby reducing the probability of the upper end cover a1 suddenly bouncing up due to excessive lifting force, and thus can reduce the risk of safety accidents when disassembling the upper end cover a1 of the generator a.

[0030] Normally, it is preferred to use a jack b to lift the load-bearing part 2 to increase the gap between the upper end cover a1 and the casing a2, because the force application method of the jack b is more stable, thereby reducing the risk of safety accidents; the load-bearing part 2 can also be lifted by hoisting to increase the gap between the upper end cover a1 and the casing a2. Although the force application method of hoisting is more difficult to control, the local adhesion between the upper end cover a1 and the casing a2 is much smaller than the overall adhesion between the upper end cover a1 and the casing a2. Therefore, the force required to lift the load-bearing part 2 is much smaller than the force of directly lifting the upper end cover a1; therefore, the safety of using hoisting to remove the adhesion between the upper end cover a1 and the casing a2 is much higher than the safety of directly lifting the upper end cover a1.

[0031] In one embodiment, the auxiliary disassembly tool 1000 further includes a reinforcing plate 3, which is disposed on the clamping part 1 and abuts against the supporting load-bearing part 2. Since the adhesive force between the upper end cover a1 and the housing a2 is too large, the connection between the clamping part 1 and the load-bearing part 2 is easily broken when the jack b is used to lift it; the reinforcing plate 3 is used to strengthen the structural strength of the connection between the clamping part 1 and the load-bearing part 2, which can reduce the probability of the jack b damaging the auxiliary disassembly tool 1000, thereby extending the service life of the auxiliary disassembly tool 1000.

[0032] Furthermore, the reinforcing plate 3 can be arranged in a rectangular structure or in a right-angled triangle structure. In one embodiment, the reinforcing plate 3 is arranged in a right-angled triangle structure, one of the two right-angled sides of the reinforcing plate 3 is arranged at the clamping part 1, and the other of the two right-angled sides of the reinforcing plate 3 abuts against the supporting load-bearing part 2. Generally speaking, the surface of the reinforcing rib a11 of the clamping part 1 that abuts against the surface of the load-bearing part 2 that abuts against the jack b, so that the direction of movement of the upper end cover a1 is consistent with the direction of force, so that the force required to separate the upper end cover a1 and the casing a2 is minimized. Therefore, the reinforcing plate 3 is arranged in a right-angled triangle, which can maximize the structural reinforcement effect of the connection between the clamping part 1 and the load-bearing part 2 while using the least material, thereby saving economic costs.

[0033] In one embodiment, the load-bearing part 2 further includes a limiting ring 21, and the limiting ring 21 is arranged on the side of the load-bearing part 2 facing away from the reinforcing plate 3. The limiting ring 21 is arranged, and the base of the jack b is placed in the limiting groove formed by the limiting ring 21 and the load-bearing part 2, which can prevent the jack b from sliding sideways due to lack of force when it has not yet contacted the casing a2 during the lifting process, thereby facilitating the user's operation. It can be understood that due to the large mass of the upper end cover a1, a hydraulically driven jack b is generally used for lifting, and the hydraulically driven jack b needs to be connected to the oil cylinder through a pipeline; therefore, in one embodiment, a notch 211 is formed on the limiting ring 21, and the pipeline can be connected to the jack b through the notch 211.

[0034] It can be understood that the clamping part 1 can be formed with at least one locking hole 12. Preferably, in one embodiment, the clamping part 1 is formed with two locking holes 12, and the two locking holes 12 are arranged at intervals along the length direction of the clamping part 1; such an arrangement ensures that the clamping part 1 will not rotate relative to the reinforcing rib a11 of the upper end cover a1 during disassembly, and at the same time, the clamping part 1 will not move relative to the reinforcing rib a11 of the upper end cover a1 in all directions in cooperation with the limiting of the clamping groove 11. In another embodiment, the clamping part 1 forms a locking hole 12, and the locking member 4 located in the locking hole 12, the clamping part 1 and the load-bearing part 2 together form a lever structure, and the locking member 4 serves as the fulcrum of the lever structure; when the jack b lifts up the load-bearing part 2, the end of the clamping part 1 away from the load-bearing part 2 moves in the opposite direction, and the end of the clamping part 1 away from the load-bearing part 2 will apply a force to the upper end cover a1 in a direction opposite to the direction in which the jack b lifts up the load-bearing part 2, so that the jack b needs to apply a greater force to eliminate the sticking force between the upper end cover a1 and the housing a2. Therefore, it is preferred that the clamping part 1 is formed with two locking holes 12.

[0035] Furthermore, the locking hole 12 can be a smooth through hole or a threaded hole. In one embodiment, the locking hole 12 is a threaded hole, and the threaded hole cooperates with the locking member 4 to better lock the clamping part 1 on the reinforcing rib a11 of the upper end cover a1.

[0036] The clamping part 1 and the load-bearing part 2 can be connected by welding or can be an integrally formed structure. In one embodiment, the clamping part 1 and the load-bearing part 2 are an integrally formed structure, so that the structural strength of the connection between the clamping part 1 and the load-bearing part 2 is higher, which can reduce the probability of the jack b damaging the auxiliary disassembly tool 1000, thereby extending the service life of the auxiliary disassembly tool 1000.

[0037] In one embodiment, the clamping part 1 further includes a bearing plate 13, which is disposed at one end of the clamping part 1 away from the bearing part 2 and is used to abut against the cover a12 of the upper end cover a1. When the clamping part 1 forms a locking hole 12, the locking member 4, the clamping part 1 and the bearing part 2 located in the locking hole 12 together form a lever structure, and the locking member 4 serves as the fulcrum of the lever structure; when the jack b lifts up the bearing part 2, the end of the clamping part 1 away from the bearing part 2 moves in the opposite direction, and at this time, the end of the clamping part 1 away from the bearing part 2 will apply a force to the upper end cover a1 in a direction opposite to the direction in which the jack b lifts up the bearing part 2. If this force is too large, the clamping part 1 will be damaged. Therefore, a load-bearing plate 13 is set on the clamping part 1, and the contact area between the clamping part 1 and the cover body a12 of the upper end cover a1 is increased, so that the pressure between the clamping part 1 and the cover body a12 of the upper end cover a1 is reduced, which can reduce the probability of damage to the clamping part 1, thereby extending the service life of the auxiliary disassembly tool 1000.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
