[0055] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application and how the technical solutions in the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0056] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein.

[0057] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0058] Wind turbines are devices that convert wind energy into electrical energy, and the gearbox is the core component of wind turbines, which can transmit the power generated by the wind rotor to the generator. The lubricating oil in the gearbox can play a role in lubrication and cooling, and the oil pump motor is the power source for the lubricating oil. After working for a long time, the oil pump motor needs to be repaired and replaced in time.

[0059] At present, the replacement of the oil pump motor is mainly carried out in a purely manual manner, which requires manual handling of the oil pump motor and lifting it to a designated position for replacement.

[0060] However, the above-mentioned replacement method of the oil pump motor has certain safety hazards.

[0061] Based on this, the present application provides a kind of oil pump motor replacement tool, including a first hanging arm, a hanger and a support arm mechanism. When the oil pump motor needs to be replaced, the staff can first fix the first hanging arm on the wind turbine generator set through the mounting hole to make the first hanging arm a stable hanging point, and then install the hanger on the first hanging arm, and connect the lifting end of the hanger with the oil pump motor lifting lug. At this time, the staff only needs to operate the hanger, and the oil pump motor can be lifted together with the lifting end of the hanger. When the oil pump motor is lifted to the specified height, the support arm mechanism is inserted into the oil pump motor lifting lug, so that the oil pump motor can maintain a stable suspended state, so that the staff can replace the oil pump motor later.

[0062] Therefore, by providing the first lifting arm, the lifting device and the supporting arm mechanism, the lifting of the oil pump motor no longer relies on manual handling. The operator only needs to operate the lifting device and use the supporting arm mechanism to lift the oil pump motor to the specified position and keep it in a stable suspended state, which not only facilitates the replacement operation of the operator, but also improves the safety during the replacement operation.

[0063] The technical solution of the present application is described in detail below with reference to the accompanying drawings using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0064] Reference Figures 1 to 5 As shown, an embodiment of the present application provides an oil pump motor replacement tool, including a first boom 100, the first boom 100 is provided with a mounting hole 110 to fix the first boom 100 on the wind turbine generator set; a hanger 200, the hanger 200 is installed on the first boom 100, and the lifting end of the hanger 200 is used to connect with the oil pump motor lifting ear to lift the oil pump motor; a support arm mechanism 300, one end of the support arm mechanism 300 is connected to the first boom 100, when the oil pump motor is lifted to a specified height, the other end of the support arm mechanism 300 is inserted into the lifting ear of the oil pump motor to support the oil pump motor.

[0065] In the present application, when the oil pump motor needs to be replaced, the staff can first fix the first boom 100 on the wind turbine generator set through the mounting hole 110 to make the first boom 100 a stable hanging point, and then install the sling 200 on the first boom 100, and connect the lifting end of the sling 200 to the lifting ear of the oil pump motor. At this time, the staff only needs to operate the sling, and the oil pump motor can be lifted along with the lifting end of the sling 200. When the oil pump motor is lifted to the specified height, the support arm mechanism 300 is inserted into the lifting ear of the oil pump motor, so that the oil pump motor can maintain a stable suspended state, which is convenient for subsequent replacement operations of the oil pump motor by the staff.

[0066] It is understandable that in the present application, the specific structure of the sling 200 is not limited, and it can be set as an electric winch, a chain hoist, etc., as long as it can lift the oil pump motor. Specifically, in the present embodiment, the sling 200 can be a chain hoist. The hook of the chain hoist is hung on the first boom 100, and the lower hook at the tail of the chain hoist lifting chain is connected to the oil pump motor ear. At this time, the operator only needs to pull the hand chain on the other side to make the lifting chain wrap around the sprocket set inside the chain hoist to lift the oil pump motor.

[0067] Thus, by providing the first lifting arm 100, the lifting device 200 and the supporting arm mechanism 300, the lifting of the oil pump motor no longer relies on manual handling. The operator only needs to operate the lifting device 200 and use the supporting arm mechanism 300 to lift the oil pump motor to a specified position and keep it in a stable suspended state, which not only facilitates the replacement operation of the operator, but also improves the safety during the replacement operation.

[0068] In some embodiments, a first connecting member is also included; a first through hole 120 is opened on the side wall of the first boom 100, and a second through hole 311 is opened on the support arm mechanism 300, and the first connecting member is inserted into the first through hole 120 and the second through hole 311 to connect the first boom 100 and the support arm mechanism 300.

[0069] In the present application, there is no restriction on the specific connection relationship between the first boom 100 and the support arm mechanism 300, which can be set as welding, etc. Specifically, in the present embodiment, the connection between the first boom 100 and the support arm mechanism 300 is set as a detachable connection with the first connecting member as a bridge, and the oil pump motor replacement tool is split into a combination of multiple parts such as the first boom 100, the support arm mechanism 300 and the sling, which is convenient for the staff to install and carry.

[0070] In some embodiments, the number of the first through holes 120 is set to at least two, and the first through holes 120 are arranged in sequence along the extension direction of the first suspension arm 100. The first connecting member is inserted into one of the first through holes 120 to adjust the support arm mechanism 300 so that it is at different positions on the first suspension arm 100.

[0071] In the present application, a plurality of first through holes are provided for adjusting the support arm mechanism 300 so that it is located at different positions on the first boom 100, so that the oil pump motor can be inserted at different positions of the support arm mechanism 300 according to the needs of the operator, thereby facilitating the subsequent replacement operation of the oil pump motor.

[0072] In some embodiments, the support arm mechanism 300 includes a suspension arm cover 310, a rotating connection assembly 320 and a second suspension arm 330, and the suspension arm cover 310, the rotating connection assembly 320 and the second suspension arm 330 are connected in sequence, wherein the second suspension arm 330 rotates relative to the rotating connection assembly 320; the suspension arm cover 310 is connected to the first suspension arm 100, and the second suspension arm 330 is used to be inserted into the lifting ear of the oil pump motor to support the oil pump motor and drive it to rotate.

[0073] In the present application, the support arm mechanism 300 is split into multiple parts, such as the arm sleeve 310, the rotating connection assembly 320 and the second arm 330, so as to facilitate installation and carrying by the staff; at the same time, the second arm 330 is configured to be rotatable relative to the rotating connection assembly 320, thereby driving the oil pump motor to rotate relative to the rotating connection assembly 320, so that the oil pump motor can be located at different positions on the rotating circle of the second arm 330 according to the needs of the operating personnel, which not only expands the scope of application of the oil pump motor replacement tooling, but also facilitates the subsequent replacement operation of the oil pump motor.

[0074] In some embodiments, a second connecting member is also included; a third through hole 312 is opened on the end of the suspension arm sleeve 310 close to the rotating connection assembly 320, and a fourth through hole 321a is opened on the rotating connection assembly 320, and the second connecting member is inserted into the third through hole 312 and the fourth through hole 321a to connect the suspension arm sleeve 310 and the rotating connection assembly 320.

[0075] In the present application, there is no limitation on the specific connection relationship between the boom cover 310 and the rotating connection assembly 320, which can be set to welding, etc. Specifically, in the present embodiment, the connection between the boom cover 310 and the rotating connection assembly 320 is set to be a detachable connection with the second connecting member as a bridge, which is convenient for installation and carrying by the staff.

[0077] In the present application, there is no limitation on the specific connection relationship between the rotating connection assembly 320 and the second suspension arm 330, which can be set as a gear transmission, etc. Specifically, in the present embodiment, the connection between the rotating connection assembly 320 and the second suspension arm 330 is set as a rotation connection with a bearing as a bridge, which reduces the friction generated by the second suspension arm 330 during the rotation process, making the rotation of the second suspension arm 330 more stable and smooth, thereby preventing the oil pump motor from shaking or even falling off when rotating with the second suspension arm 330, thereby improving the safety of the oil pump motor replacement operation.

[0078] In some embodiments, a first stopper 323 is further included; a fifth through hole 331 a is formed on the side wall of the rotating sleeve 331 , and the first stopper 323 is inserted into the fifth through hole 331 a and abuts against the outer wall of the rotating shaft 321 .

[0083] In the present application, a second limit member 332 is inserted into the sixth through hole 333 to limit the oil pump motor ear from being inserted into the second suspension arm 330, thereby preventing the oil pump motor from falling off when rotating with the second suspension arm 330; at the same time, a detachable connection is provided between the second limit member 332 and the second suspension arm 330, so as to facilitate the oil pump motor to be inserted into or slide out of the second suspension arm 330.

[0084] In some embodiments, the limit assembly also includes a limit plate 334; the limit plate 334 includes a first connecting plate 334a and a second connecting plate 334b, the first connecting plate 334a extends in a horizontal direction and is arranged at the end of the second boom 330 away from the rotating connection assembly 320, and the second connecting plate 334b ​​extends in a vertical direction and is arranged at the end of the first connecting plate 334a away from the second boom 330.
