Description

Technical Field

[0001] The present application relates to the technical field of mechanical maintenance tools, and in particular to a gear box oil pump motor disassembly tool. Background Art

[0002] The gearbox is an important mechanical component that is widely used in wind turbines. Its main function is to transmit the power generated by the wind wheel under the action of wind to the generator and make it obtain the corresponding speed. The oil pump motor is installed in the gearbox to pump oil into the gearbox.

[0003] When repairing the oil pump motor, due to the narrow space in the gear box during maintenance, the motor fixing bolts on the gear box side and the motor fixing back plate bolts cannot be tightened due to the narrow space, resulting in insufficient bolt torque value. When the oil pump motor runs for a long time, the motor shaft is in an unstable state, causing the motor coupling to wear too quickly and frequent failures. The existing disassembly method is mainly manual knocking, but this method can easily cause damage to the fixed mounting holes of the motor.

[0004] In view of the above problems, the inventor proposes a gear box oil pump motor disassembly tool. Summary of the invention

[0005] In order to solve the problem that the fixing and mounting holes of the gearbox oil pump motor are easily damaged when the motor is manually knocked, the utility model aims to provide a gearbox oil pump motor disassembly tool.

[0009] In a possible implementation, the other end of the first connecting rod and the other end of the second connecting rod are both fixedly mounted with connecting sleeves, and the connecting shaft passes through the two connecting sleeves.

[0010] In a possible implementation, a screw is threadedly mounted on one end of each of the two connecting sleeves, a plurality of evenly distributed threaded holes are opened in the middle of the connecting shaft, and the screw is threadedly connected to the inner wall of the threaded hole.

[0011] In a possible implementation, both ends of the two screw rods are threadedly rotatably mounted with hexagonal nuts, wherein one side of two adjacent hexagonal nuts is in movably contact with an outer wall of a connecting sleeve.

[0012] In a possible implementation manner, a rubber sleeve is fixedly mounted on one end of the first connecting rod and one end of the second connecting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model forms a Z-shaped disassembly tool by connecting the first connecting rod, the second connecting rod, the sleeve head and the hexagonal sleeve, which can be used to loosen the bolts and tighten the torque in the narrow space of the motor back plate, so that the motor fixing direction and verticality meet the standards, and prevent the motor from shaking and losing stability when it is not fixed firmly.

[0026] Example 1

[0027] like Figure 1-5 As shown, the utility model provides a gearbox oil pump motor disassembly tool, which includes a first connecting rod 1 and a second connecting rod 2. A socket head 11 is fixedly installed at one end of the first connecting rod 1, and the diameter of the socket head 11 is 18 mm. A hexagonal socket 21 is fixedly installed at one end of the second connecting rod 2, and the diameter of the hexagonal socket 21 is 10 mm. The first connecting rod 1, the second connecting rod 2, the socket head 11 and the hexagonal socket 21 are connected to form a Z-shaped wrench, and an adjustment mechanism 3 is provided between the first connecting rod 1 and the second connecting rod 2.

[0028] In a possible embodiment, a rubber sleeve 22 is fixedly installed on one end of the first connecting rod 1 and one end of the second connecting rod 2. By providing the rubber sleeve 22, the stability of the operator when holding the first connecting rod 1 or the second connecting rod 2 for operation is improved to avoid slipping.

[0029] In a possible embodiment, the adjusting mechanism 3 includes a connecting shaft 31, both ends of the connecting shaft 31 are provided with external thread grooves 32, one end of the first connecting rod 1 away from the sleeve head 11 and the other end of the second connecting rod 2 away from the hexagonal sleeve 21 are provided with a cavity 33, and the inner walls of the two cavities 33 are provided with internal threaded screws 34, one of the internal threaded screws 34 and an external threaded groove 32 are threadedly connected. By setting the connecting shaft 31, the external threaded groove 32, the cavity 33 and the internal threaded screw 34, when the external threaded groove 32 is threadedly connected to the internal threaded screw 34 at the end of the first connecting rod 1 or the second connecting rod 2, the first connecting rod 1 is connected to the second connecting rod 2 through the connecting shaft 31. At the same time, the spacing between the first connecting rod 1 and the second connecting rod 2 can be adjusted so that the total length of the disassembly tool changes to adapt to different disassembly environments. The first connecting rod 1 or the second connecting rod 2 can also be used alone to improve the flexibility of the disassembly tool.

[0030] In a possible embodiment, one end of the first connecting rod 1 away from the sleeve head 11 and one end of the second connecting rod 2 away from the hexagonal sleeve 21 are fixedly installed with a connecting sleeve 35, the connecting shaft 31 passes through the two connecting sleeves 35, and one end of the two connecting sleeves 35 are threadedly installed with a screw 36. A plurality of evenly distributed threaded holes 38 are opened in the middle of the connecting shaft 31, and the screw 36 and the inner wall of the threaded hole 38 are threadedly connected. By providing the connecting sleeve 35, the screw 36 and the plurality of threaded holes 38, when the screw 36 is screwed into different threaded holes 38, the first connecting rod 1 or the second connecting rod 2 can be fixed to the connecting shaft 31, and the distance between the first connecting rod 1 and the second connecting rod 2 can be adjusted.

[0031] In a possible embodiment, both ends of the two screw rods 36 are threadedly installed with hexagonal nuts 37, wherein one side of two adjacent hexagonal nuts 37 is in movable contact with the outer wall of a connecting sleeve 35, and the screw rods 36 are fixed by setting the hexagonal nuts 37, thereby improving the stability of the screw rods 36, and further improving the stability between the first connecting rod 1 or the second connecting rod 2 and the connecting shaft 31.

[0032] Working principle:

[0033] When it is necessary to repair and disassemble the fan gearbox oil pump motor, the bolt space inside the motor is small. The operator removes the motor back plate fixing bolts through the socket head 11, removes the motor fixing bolts through the hexagonal socket 21, and then replaces them. When the replacement is completed and the bolt torque needs to be tightened, the socket head 11 is aligned with the bolts on the inner side of the motor back plate to tighten the torque to ensure that the torque value meets the standard. The staff uses a Z-shaped wrench to check the torque again to keep the motor and the oil pump in a vertical state, and the fan gearbox oil pump motor repair and disassembly is completed;

[0034] When it is necessary to adjust the overall length of the disassembly tool, the operator can adjust the separation or approach between the first connecting rod 1, the second connecting rod 2 and the connecting shaft 31 through the threaded connection between the two internal threaded screws 34 and the two external threaded grooves 32, and screw the two screws 36 into the corresponding threaded holes 38, and then lock the two screws 36 through four hexagonal nuts 37 to achieve the adjustment of the overall length of the disassembly tool. At the same time, the first connecting rod 1 or the second connecting rod 2 can be threadedly connected to the connecting shaft 31 separately to adapt to different disassembly environments, while improving the flexibility of the disassembly tool.

[0035] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, various changes and modifications made without departing from the concept of the present application should be deemed to belong to the protection scope of the present application.
