Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to an embedded hoisting mechanism for a variable pitch motor stator assembly. Background Art

[0002] In the field of wind power generation, the hoisting and assembly of variable-pitch motor stator assemblies is a critical process, with its safety and reliability directly impacting the operating efficiency and maintenance costs of wind turbines. Traditional hoisting mechanisms often utilize a top-mounted, lift-up unlocking mechanism. This mechanism, due to its numerous internal components, is susceptible to external influences during the hoisting process and motor assembly. This can lead to misoperation of the unlocking element, causing the stator assembly to accidentally fall off, posing a significant safety hazard to on-site workers and equipment. Furthermore, the unlocking element in this top-mounted structure is exposed to dust, oil, and other contaminants, compromising its proper function. Utility Model Content

[0005] A safety mechanism is arranged inside the pulling plate, which is used to lock the pulling plate and the lifting rod.

[0007] In the initial state, the elastic element is in a compressed state, so that the locking seat abuts against the suspension rod, and the unlocking button abuts against the end of the locking seat away from the suspension rod.

[0008] In order to solve the problem of insufficient contact between the locking seat and the suspension rod, an abutment portion is further formed on one end of the locking seat close to the suspension rod, and the abutment portion is made of rubber.

[0009] In order to solve the problem that multiple locking seats cannot be linked and unlocked, a safety mechanism is further provided, including a linkage seat and a linkage rod.

[0011] It further includes a base installed at the bottom of the suspension rod, and the base is used to limit the rotation of the second connecting rod.

[0012] The beneficial effects of the present invention are as follows: the present invention provides an embedded lifting mechanism for the stator assembly of a variable pitch motor, which realizes the locking of the pulling plate and the lifting rod by arranging a safety mechanism in the pulling plate, ensuring that the pulling plate can only move downward in one direction when not unlocked, effectively preventing the stator from falling due to accidental hooking of the unlocking element, and improving the safety during the lifting process; the unlocking button is arranged on the bottom surface of the pulling plate, which avoids the situation where the internal elements accidentally touch the unlocking element during the motor assembly process, and reduces the risk of unlocking the lifting mechanism due to misoperation.

DETAILED DESCRIPTION

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0019] like Figure 1 This is a structural schematic diagram of the present invention, an embedded lifting mechanism of a variable pitch motor stator assembly, including a boom 1, a pulling disc 2, a connecting seat 3, a first connecting rod 4, a second connecting rod 5 and at least two support arms 6. Three support arms 6 are installed in this application, and two spaced-apart connecting seats 3 are installed on the boom 1. The pulling disc 2 and the boom 1 are slidingly connected, and the connecting seat 3 and the boom 1 are fixedly connected. The connecting seat 3 is located below the pulling disc 2. One end of the first connecting rod 4 is rotatably connected to the pulling disc 2, and the other end is rotatably connected to the support arm 6. One end of the second connecting rod 5 is rotatably connected to the connecting seat 3, and the other end is rotatably connected to the support arm 6. A limiting seat 8 is arranged on the boom 1, and the limiting seat 8 is located between the pulling disc 2 and the connecting seat 3. The limiting seat 8 is used to limit the movement of the pulling disc 2 to avoid its excessive movement. A base 9 is installed at the bottom of the boom 1, and the base 9 is used to limit the rotation of the second connecting rod 5.

[0020] like Figure 2 As shown, a safety mechanism 7 is arranged in the pulling disc 2, and the safety mechanism 7 is used to lock the pulling disc 2 and the boom 1. By arranging the safety mechanism 7 in the pulling disc 2, the pulling disc 2 and the boom 1 are locked, ensuring that the pulling disc 2 can only move downward in one direction when not unlocked, effectively preventing the stator from falling due to accidental hooking of the unlocking element, and improving the safety during the lifting process.

[0021] like Figure 2 、 Figure 3When the cam 72 is in the unlocking state, the locking cam 721 is in the unlocking state, and the locking cam 722 is in the unlocking state, so that the cam 722 can be unlocked.

[0022] In the initial state, the elastic element 722 is in a compressed state, so that the locking seat 721 is against the suspension rod 1, that is, the abutting part 7211 of the locking seat 721 is against the suspension rod 1, and the unlocking button 71 is against the end of the locking seat 721 away from the suspension rod 1. The unlocking button 71 can also play a limiting role to prevent the suspension rod 1 from driving the locking seat 721 when the pull plate 2 moves upward.

[0023] An abutment portion 7211 is formed on one end of the locking seat 721 close to the suspension rod 1. The locking seat 721 is a rod-shaped structure, and the abutment portion 7211 is an arc-shaped structure. The abutment portion 7211 is rubber. The rubber can increase the friction, making it difficult for the pull plate 2 to move upward relative to the suspension rod 1, thereby locking the position of the pull plate 2. The pull plate 2 cannot be moved when it is lifted alone, thereby improving safety.

[0024] like Figure 2 、 Figure 3 As shown, the safety mechanism 7 includes a linkage seat 723 and a linkage rod 724. The linkage seat 723 is slidingly connected to the suspension rod 1. One end of the linkage rod 724 is rotationally connected to the linkage seat 723, and the other end is rotationally connected to the end of the locking seat 721 away from the suspension rod 1, thereby realizing synchronous unlocking of multiple locking assemblies 72, so that multiple locking assemblies 72 can be installed in the pull plate 2, thereby enhancing the locking effect.

[0025] When the pull tray 2 moves downward, the suspension rod 1 can squeeze open the locking seat 721 so that the pull tray 2 can move downward.

[0026] When the pull plate 2 moves upward and is in an unlocked state, the elastic element 722 is in a compressed state, so that the abutment portion 7211 of the locking seat 721 abuts against the suspension rod 1, so that the pull plate 2 and the suspension rod 1 are locked, and through the abutment of the unlocking button 71, the rotation of the locking seat 721 can be limited, further improving the locking effect.

[0027] When the pull plate 2 moves upward and is in the unlocked state, the unlock button 71 is pressed, and the unlock button 71 rotates the locking seat 721, that is, the abutting portion 7211 moves away from the suspension rod 1 so that the pull plate 2 can move upward.

[0028] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
