[0016] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments of this specification and, together with their description, serve to explain the principles of this specification.

[0017] Figure 1 This is a schematic diagram of the lifting fixture and the workpiece to be operated during the lifting process in the embodiments of this application;

[0018] Figure 2 This is an isometric view of the hoisting fixture;

[0019] Figure 3 for Figure 1 A partial structural cross-sectional view. Detailed Implementation

[0020] To achieve the above objectives, this utility model provides a lifting fixture, such as... Figure 1and Figure 2 As shown, Figure 1 This is a schematic diagram of the lifting fixture and the workpiece 10c to be operated during the lifting process in the embodiments of this application; Figure 2 This is an isometric view of the hoisting fixture.

[0021] The hoisting fixture includes a support part 1 and a movable part 2 connected to the support part 1 (the movable part 2 is in...). Figure 1 The middle part is obscured; see also: Figure 2 (Understanding the moving part 2). The moving part 2 is held above the workpiece 10c by the support part 1. The support part 1 can be a bracket structure to achieve precise positioning of the moving part 2 to a preset elevation, or a hanger structure to suspend it in the top area of ​​the workpiece 10c.

[0022] The movable part 2 is used to connect to the lifting part 3, which is used to lift the workpiece 10c. The lifting part 3 can be a hand-operated hoist or winch, or other device capable of moving the workpiece 10c in the lifting direction for lifting operations. For the connection between the movable part 2 and the lifting part 3, the movable part 2 can be equipped with a hook 21, or other devices can be used to connect it to the lifting part 3. Figure 1 In the example shown, the lifting direction is Figure 1 The y-direction in the figure refers to the height direction of the hoisting equipment.

[0023] The movable part 2 can move relative to the support part 1 along a first direction x to move the lifting part 3 to a set position. The first direction x is angled to the lifting direction of the operable component 10c; that is, the first direction x forms an angle with the lifting direction, which can be acute, obtuse, or right angle. The first direction x can be as follows: Figure 1 The horizontal extension shown can also be set at an acute or obtuse angle to the horizontal direction, which can be chosen by those skilled in the art.

[0024] In traditional technical solutions, during the inspection and maintenance of the wind turbine bearing housing, it is necessary to temporarily find hanging points or make special frames to support the hand-operated hoist for hoisting the workpiece 10c. Finding temporary hanging points often makes it difficult to find suitable and stable locations. Furthermore, relatively fixed hanging points mean that once the workpiece 10c is hoisted, it cannot be placed in another location. This forces workers to work directly below the workpiece 10c, which poses a direct threat to their safety should the workpiece slip or shake.

[0025] By using the hoisting fixture of this application, the moving part 2 can move relative to the supporting part 1 in the first direction x, thereby driving the hoisting part 3 located on it to move in the first direction x. This allows the moving part 2 to move the part to be operated 10c to a position away from the operator after the part to be operated is hoisted, thereby improving the safety of the operator. In addition, during the inspection and maintenance process, it is only necessary to move the hoisting fixture of this application to the fan that needs to be operated, without having to temporarily find a hoisting point during the maintenance and inspection process, thereby improving the efficiency of the inspection and maintenance of the fan bearing chamber.

[0026] In some alternative embodiments, the support portion 1 includes at least one support assembly 11; the support assembly 11 includes at least one support member 111 for supporting the movable portion 2. One support assembly 11 is disposed on one side of the operable part 10c. Alternatively, multiple support assemblies are disposed around the operable part 10c.

[0027] In such Figure 2 In the example shown, the support portion 1 is shown to be configured with a support assembly 11. The support assembly 11 includes two support members 111. The two support members 111 are distributed opposite to each other. One end of the movable portion 2 is indirectly fixed to the top end of one support member 111, and the other end of the movable portion 2 is indirectly fixed to the top end of the other support member 111.

[0028] exist Figure 1 and Figure 2 In the middle, the support part 1 includes a support component 11, and the support component 11 is disposed on one side of the part to be operated 10c.

[0029] Of course, the support part 1 may also include two support components 11, which are respectively disposed on both sides of the workpiece 10c to be operated. Alternatively, the support part 1 may include three or four support components 11. When two or more support components 11 are provided, the multiple support components 11 can be arranged around the workpiece 10c to be operated.

[0030] In this way, the support part 1 can effectively support the moving part 2, thereby keeping the moving part 2 in the set position.

[0031] In such Figure 1 , Figure 2 and Figure 3 In the technical solution shown, Figure 3 for Figure 1 A partial structural cross-sectional view. The support part 1 also includes a guide part 12, and the movable part 2 can slide and adapt to the guide part 12.

[0032] Specifically, such as Figure 2 and Figure 3As shown, the guide portion 12 has a groove 121 extending along the first direction x, and a slider 21 is disposed in the groove 121. The slider 21 is fixedly connected to the moving portion 2. Figure 2 As shown, the top of the support member 111 is provided with two guide portions 12 extending along the first direction x. The slider 21 provided on the moving part 2 is located in the slide groove 121 and can slide and adapt to the slide groove 121. As a result, the stability of the moving part 2 in the first direction x can be improved, and the positional deviation of the moving part 2 during movement can be avoided.

[0033] In a more specific example, the lifting fixture includes a drive unit 4, which is connected to the moving unit 2 via a transmission. The drive unit 4 can be fixedly connected to one end of the guide unit 12, and can be a motor or an electric actuator, etc. The output end of the drive unit 4 can be connected to the slider 21 or via a transmission.

[0034] exist Figure 3 In the example shown, the drive unit 4 is a motor. A lead screw 41 is installed inside the slide groove 121, and the lead screw 41 is connected to the output end of the motor. A slider 21 is sleeved on the lead screw 41, and a threaded pair is formed between the lead screw 41 and the slider 21. Thus, the moving part 2 can be driven to move along the first direction x.

[0035] In the aforementioned embodiments, the support member 111 is provided with a wheel portion 112. The wheel portion 112 is provided at the bottom of the support member 111 to drive the various components located thereon to move, thereby facilitating the movement of the hoisting fixture in this application to the required position.

[0036] In other embodiments of this application, the support assembly 11 includes a stop 5 that is directly or indirectly connected to the support member 111. The stop 5 is configured to stop the fixedly mounted adapter 6 on one or both sides along the second direction y. By providing a stop that can stop the adapter 6 on both sides along the second direction y, tilting of the lifting fixture can be prevented during the movement of the moving part 2 along the first direction x.

[0037] In a specific example, please see Figure 1 To be understood. The part to be operated 10 is the end cover of the bearing chamber 10b located at the top of the fan body 10a. The end cover is used to seal the bearing chamber 10b and is located at the top of the bearing chamber 10b. The fan body 10a is mounted on the mounting foundation 10d, which can be a reinforced concrete base or the like.

[0038] The fan body 10a is fixed to the mounting base 10d. The adapter 6 can be fixed to the fan body 10a; it can be fixed to the mounting base 10d; or it can be fixed to the ground, as long as it can stop the obstruction on both sides of the stop 5 in the second direction y. The second direction y is set at an acute angle, an obtuse angle, or a right angle with the first direction x. For example, the second direction y can be... Figure 1 The vertical direction in the middle.

[0039] In such Figure 1 In the example shown, the adapter 6 is a steel structure welded to the fan body 10a. The adapter 6 has an upper surface and a lower surface distributed along the second direction y, and a gap is formed between the lower surface of the adapter 6 and the mounting base 10d.

[0040] A portion of the stop 5 can be located within the gap and abut against the second surface of the adapter 6 in the second direction y. A portion of the stop 5 can be located on the side of the adapter 6 away from the second surface and abut against the first surface of the adapter 6.

[0041] In a more specific example, the stop 5 includes two stop arms 51 spaced apart along the second direction y, with the adapter 6 between the two stop arms 51. At least one stop arm 51 is provided with a pressing member 52, at least a portion of which is located between the two stop arms 51, and the pressing member 52 is movable along the second direction y to abut or move away from the adapter.

[0042] In such Figure 1 and Figure 2 In the example shown, the stop arms 51 are a first stop arm 511 and a second stop arm 512, which are distributed along the second direction y. The first stop arm 511 is within the aforementioned gap and abuts against the second surface of the adapter 6, while the second stop arm 512 is spaced apart from the adapter 6. The pressing member 52 is threadedly fitted to the second stop arm 512 and is movable along the second direction y to press against or move away from the first surface of the adapter 6.

[0043] In this way, the stop 5 can be adapted to the adapter 6 of different sizes, thereby improving the compatibility and adaptability of the lifting fixture.

[0044] Of course, it is also possible to provide pressing parts 52 on both stop arms 51, which can be selected by those skilled in the art.

[0045] In this embodiment, the first stop arm 511 and the second stop arm 512 are directly or indirectly fixedly connected. Specifically, one end of the second stop arm 512 is provided with a mounting plate 513, which extends along the second direction y and is welded to the first stop arm 511, thereby fixing the first stop arm 511 and the second stop arm 512 together.

[0046] Alternatively, the first stop arm 511 can be fixedly connected to the support assembly 11, and the second stop arm 512 can also be fixedly connected to the support assembly 11. Those skilled in the art can choose for themselves.

[0047] In other embodiments of this application, the stop 5 can be locked at different positions on the support 111 along at least one of the second direction y and the third direction z. That is, the mounting position of the stop 5 in the second direction y is adjustable. Alternatively, the mounting position of the stop 5 in the third direction z is adjustable. Or, the positions of the stop 5 in both the second direction y and the third direction z are adjustable. This further increases the compatibility and adaptability of the lifting fixture.

[0048] In a specific example, the support assembly 11 includes a connecting portion 113, a transition portion 53 fixedly connected to the stop portion 5, a connecting rod 114, and a locking member 115 connected to the connecting rod 114. The transition portion 53 has a first hole 53a extending in a second direction, and the connecting portion 113 has a second hole 113a extending in a third direction; part of the connecting rod 114 is located in the first hole 53a, and part is located in the second hole 113a; one end of the connecting rod 114 can be stopped axially with one of the connecting portion 113 and the transition portion 53, and the other end is provided with the locking member 115.

[0049] In a specific example, the adapter 53 has a first hole 53a extending in the second direction y, and the connecting part 113 has a second hole 113a extending in the third direction z. A portion of the connecting rod 114 is slidably fitted into the first hole 53a, and a portion of the connecting rod 114 is slidably fitted into the second hole 113a, and can stop against the second hole 113a along the axial direction of the connecting rod 114. The portion of the connecting rod 114 equipped with a locking member 115 is located on the side of the first hole 53a away from the second hole 113a. The locking member 115 may be threadedly fitted into the connecting rod 114 to press the connecting part 113 and the adapter 53 together.

[0050] Wherein, the first hole 53a is an elongated hole or a circular hole spaced apart along the second direction y; and / or, the second hole 113a is an elongated hole or a circular hole spaced apart along the third direction. This is sufficient to allow adjustment of the stop 5 in both the second direction y and the third direction z. The elongated hole can be an oblong hole, a rectangular hole, or an oblong hole.

[0051] In this way, the integration of the support component 11 can be improved, enabling the stop 5 to move along the second direction y and the third direction z, while also reducing the structural complexity of the hoisting fixture.

[0052] Specifically, one end of the connecting portion 113 belonging to the same support assembly 11 is fixed to one support member 111, and the other end is fixed to another support member 111. The connecting portion 113 extends in the third direction (z). The second hole 113a can be a slot or a through hole. When the second hole 113a is a slot, one end of the connecting rod 114 is located in the slot and can abut against the wall of the slot along the axial direction of the connecting rod 114. Of course, when the second hole 113a is a through hole, the second hole 113a penetrates the connecting portion 113, thereby allowing the connecting rod 114 to pass through the connecting portion 113 and connect with the locking member 115.

[0053] The adapter 53 extends along the second direction y and has a first hole 53a, which can also be a slot or a through hole.

[0054] In other words, one of the second hole 113a and the first hole 53a can be a through hole, and the other can be a slot. One end of the connecting rod 114 is located in the slot and can stop with the slot along the axial direction of the connecting rod 114. The other end passes through the through hole to the side of the through hole away from the slot and is threaded into the locking member 115.

[0055] Alternatively, both the second hole 113a and the first hole 53a can be through holes, with one end of the connecting rod 114 located on the side of the connecting part 113 away from the adapter part 53 and threadedly adapted to the locking member 115; the other end of the connecting rod 114 is located on the side of the adapter part 53 away from the connecting part 113 and threadedly adapted to the locking member 115.

[0056] In a more specific example, the adapter 53 includes a first plate 531 and a second plate 532. The connecting part 113 is located between the first plate 531 and the second plate 532. The first plate 531 has a through hole as a first hole 53a, and the side of the connecting part 113 facing the first plate 531 has a second hole 113a, which is a slot.

[0057] One end of the connecting rod 114 is embedded in a slot and is stopped axially by a baffle provided at the end of the connecting rod 114 and the slot. The other end of the connecting rod 114 passes through the first hole 53a to the side of the adapter 53 away from the connecting part 113 and is threadedly fitted with the locking member 115. By operating the locking member 115, the first plate 531 can be pressed axially against the connecting part 113, and at the same time, the second plate 532 can be driven to abut against the other side of the connecting part 113 axially.

[0058] In this way, the stop 5 can be locked in different positions, thereby further improving the compatibility and adaptability of the lifting equipment.
