Description

Technical Field

[0001] This utility model relates to the field of coil lifting device technology, and specifically to a coil lifting device. Background Technology

[0002] In the existing transformer assembly process, the high-voltage and low-voltage coils are hoisted and assembled by using hoisting tools to move the coils from the coil semi-finished product area to the transformer assembly area. Depending on the diameter of the coil, the diameter range of the lifting claws needs to be adjusted according to the outer diameter and width of the coil before hoisting.

[0003] In existing technologies, coil lifting devices are usually stored on lifting device racks. Workers climb ladders up the racks and manually adjust the position of the lifting claws. On the one hand, the adjustment process is quite troublesome, requiring manual climbing up and down to make adjustments. On the other hand, workers climbing ladders are prone to falling from heights, posing a certain safety risk.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a coil lifting tool to solve the technical problem that adjusting the diameter of the lifting claws of the coil lifting tool is inconvenient in the related art.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: A coil lifting device is provided, comprising: a lifting device body and a lifting beam, the lifting beam being fixedly connected to the lifting device body, the lifting beam extending horizontally, a slide rail being installed on the lifting beam, the extension direction of the slide rail being the same as the extension direction of the lifting beam; a lifting arm, one end of the lifting arm being provided with a lifting claw, the other end of the lifting arm being installed with a slider, the slider being slidably connected to the slide rail; an adjusting device, the adjusting device comprising a plurality of adjusting grooves formed on the lifting beam along the extension direction of the lifting beam and spring balls, the spring balls being fixedly disposed at one end of the lifting arm near the lifting beam, the spring balls being rotatably connected to the plurality of adjusting grooves; wherein, both the lifting beam and the lifting arm comprise at least two, and a receiving space for accommodating the coil is formed between the at least two lifting arms.

[0007] Furthermore, the boom includes a boom body and a connecting component. The connecting component is connected to the end of the boom body near the lifting beam, and a slider and spring ball are installed on the connecting component.

[0008] Furthermore, the coil lifting device includes a limiting device, which includes a limiting pin fixedly connected to the boom body and a limiting hole opened on the lifting beam. The limiting pin extends along the height direction. The boom body is movably connected to the connecting component, and the boom body is movably set along the height direction.

[0009] Furthermore, there are multiple limiting holes, which are opened on the lifting beam along the extension direction of the lifting beam, and the multiple limiting holes are set one-to-one with multiple adjusting grooves.

[0010] Furthermore, the coil lifting device includes: a connecting rod extending along the height direction and fixedly connected to one end of the boom body near the lifting beam; a first fixing plate fixedly inserted through the connecting rod, with a fixing plate limiting member provided on the connecting component, the fixing plate limiting member abutting against the first fixing plate; a second fixing plate arranged parallel to the first fixing plate and fixedly installed on the connecting component; and an elastic member inserted through the connecting rod, with both ends of the elastic member abutting against the first fixing plate and the second fixing plate, respectively.

[0011] Furthermore, the fixed plate limiting component includes a movable groove, which is formed on the connecting component. The first fixed plate passes through the movable groove and is slidably connected to the movable groove along the height direction. A limiting pin is installed at the end of the first fixed plate away from the connecting rod.

[0012] Furthermore, the lifting beam includes a mounting platform, which protrudes from the lifting beam and has several adjustment slots.

[0013] Furthermore, the coil lifting device includes an extension plate, which is perpendicular to the lifting beam and is fixedly connected to the lifting beam. Multiple limiting holes are provided on the extension plate.

[0014] Furthermore, the lifting beam includes a clearance groove, which is disposed between the mounting platform and the extension plate, and a slide rail is installed inside the clearance groove.

[0015] Furthermore, the lifting beams include four beams, which are arranged in a circular array around the axis of the lifting device body; the booms include four booms, which are set one-to-one with the four lifting beams.

[0016] Beneficial effects:

[0017] 1. The system of slide rails and sliders allows users to easily and manually adjust the boom position. The boom can move freely in the horizontal direction, and the distance between the lifting claws can be adjusted as needed to accommodate coils of different diameters. Spring balls are rolled into the adjustment slots, providing a simple and effective locking mechanism. When the boom is moved to the desired position, the spring balls engage with the corresponding adjustment slots, ensuring the boom is securely fixed in that position. By observing the position of the spring balls in the adjustment slots, the distance the boom has moved can be determined. This not only allows for precise adjustment but also ensures stability after adjustment. In practical use, the operator stands on the ground and can move the boom relative to the lifting beam by pushing and pulling, thus quickly completing the boom adjustment. This greatly simplifies the adjustment process, eliminating the need to climb the lifting device's mounting frame and enabling rapid position adjustment. This solves the technical problem of inconvenient adjustment of the lifting claw diameter in coil lifting devices in related technologies.

[0018] 2. The movement of the main body of the boom can drive the limit pin to move along the height direction. When the load such as the coil is loaded onto the lifting claw, the boom will move downward under the action of gravity, so that the limit pin can be inserted into the corresponding limit hole to fix the height direction. This limits the boom and prevents it from sliding or deviating during use. Through the locking effect of the limit device, the accidental displacement of the boom during operation is effectively avoided, improving the stability and safety of the lifting operation.

[0019] 3. By setting up an elastic element, when the coil lifting device is not loaded with heavy objects, the elastic element can provide a restoring force, causing the boom to move upward and automatically return to its original position, thereby disengaging the limit pin from the limit hole. After that, the boom can be pushed and pulled at will, thereby adjusting the position of the boom and facilitating the adjustment of dimensions when lifting the coil again.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] According to an embodiment of this utility model, a coil lifting tool is provided. Please refer to [link / reference]. Figures 1 to 4 The device includes: a lifting body 1 and a lifting beam 2, the lifting beam 2 being fixedly connected to the lifting body 1, the lifting beam 2 extending horizontally, a slide rail 21 mounted on the lifting beam 2, the extension direction of the slide rail 21 being the same as the extension direction of the lifting beam 2; a lifting arm 3, one end of the lifting arm 3 being provided with a lifting claw 4, the other end of the lifting arm 3 being mounted with a slider 321, the slider 321 being slidably connected to the slide rail 21; and an adjusting device, the adjusting device including a plurality of adjusting grooves 22 formed on the lifting beam 2 along the extension direction of the lifting beam 2 and spring balls 5, the spring balls 5 being fixedly set at one end of the lifting arm 3 near the lifting beam 2, the spring balls 5 being rotatably connected to the plurality of adjusting grooves 22; wherein, both the lifting beam 2 and the lifting arm 3 include at least two, and a receiving space for accommodating the coil is formed between the at least two lifting arms 3.

[0028] It should be noted that by selecting the specifications of the spring ball 5, a suitable clamping force can be obtained, which can ensure that the operator can push and pull the boom 3 without too much effort. At the same time, the spring ball 5 can be stably connected to the adjusting groove 22 when the boom is stationary or when it is slightly impacted by the coil lifting device.

[0029] Specifically, through the slide rail and slider system, users can easily and manually adjust the position of the boom 3. The boom 3 can move freely in the horizontal direction, and the distance between the lifting claws 4 can be adjusted as needed to accommodate coils of different diameters. The spring ball 5 is rolled into the adjustment groove 22, providing a simple and effective locking mechanism. When the boom 3 is moved to the desired position, the spring ball 5 will embed into the corresponding adjustment groove 22, ensuring that the boom 3 is firmly fixed in this position. By observing the position of the spring ball 5 in the adjustment groove 22, the movement distance of the boom 3 can be determined. This not only allows for precise adjustment but also ensures the stability after adjustment. In actual use, the operator stands on the ground and can move the boom 3 relative to the lifting beam 2 by pushing and pulling the boom 3, thereby quickly completing the adjustment of the boom 3. This greatly simplifies the adjustment process, eliminating the need to climb the lifting device's mounting frame and enabling rapid position adjustment. This solves the technical problem of the inconvenience of adjusting the diameter of the lifting claws in coil lifting devices in related technologies.

[0030] In the coil lifting device of this embodiment, see Figure 1 The boom 3 includes a boom body 31 and a connecting component 32. The connecting component 32 is connected to one end of the boom body 31 near the lifting beam 2. A slider 321 and a spring ball 5 are installed on the connecting component 32. In this way, the slider 321 and the spring ball 5 are integrated on the connecting component 32, realizing a modular design, which makes the assembly and maintenance of the boom 3 simpler and reduces manufacturing and maintenance costs.

[0031] In the coil lifting device of this embodiment, see Figure 3 and Figure 4 The coil lifting device includes a limiting device, which comprises a limiting pin 61 fixedly connected to the boom body 31 and a limiting hole 62 opened on the lifting beam 2. The limiting pin 61 extends along the height direction. The boom body 31 is movably connected to the connecting component 32, and the boom body 31 is movably set along the height direction. In this way, moving the boom body 31 can drive the limiting pin 61 to move along the height direction. When the load such as the coil is loaded onto the lifting claw 4, the boom 3 will move downward under the action of gravity, thereby causing the limiting pin 61 to insert into the corresponding limiting hole 62, achieving height fixation, thus limiting the boom 3 and preventing the boom 3 from sliding or deviating during use. Through the locking effect of the limiting device, the accidental displacement of the boom during operation is effectively avoided, improving the stability and safety of the lifting operation.

[0032] In the coil lifting device of this embodiment, see Figure 3The limiting holes 62 include multiple holes, which are formed on the lifting beam 2 along the extension direction of the lifting beam 2. Each limiting hole 62 corresponds to a different adjusting groove 22. In this way, the user can limit the lifting operation by adjusting the boom 3 to any position.

[0033] In some embodiments, the axes of the multiple limiting holes 62 are collinear with the axes of the multiple adjusting grooves 22. Users can directly determine the horizontal position of the boom 3 on the slide rail by observing the limiting holes 62, which facilitates the adjustment of the boom 3.

[0034] In the coil lifting device of this embodiment, see Figure 3-4 The coil lifting device includes: a connecting rod 311, which extends along the height direction and is fixedly connected to one end of the boom body 31 near the lifting beam 2; a first fixing plate 312, which is fixedly inserted through the connecting rod 311, and a fixing plate limiting member is provided on the connecting component 32, which abuts against the first fixing plate 312; a second fixing plate 322, which is parallel to the first fixing plate 312 and fixedly installed on the connecting component 32; and an elastic member 7, which is inserted through the connecting rod 311, with both ends abutting against the first fixing plate 312 and the second fixing plate 322, respectively. Thus, the first fixing plate 312 is located above the second fixing plate 322, the connecting rod 311 provides support for the elastic member 7, the connecting rod 311 is movably connected to the second fixing plate 322, and the first fixing plate 312 is fixedly connected to the connecting rod 311.

[0035] By setting the elastic element 7, when the coil lifting device is not loaded with heavy objects, the elastic element 7 can provide a restoring force, causing the lifting arm 3 to move upward and automatically return to its original position, thereby disengaging the limit pin 61 from the limit hole 62. After that, the lifting arm 3 can be pushed and pulled at will, thereby adjusting the position of the lifting arm 3, which is convenient for adjusting the size when lifting the coil again.

[0036] The first fixed plate 312 is limited by the fixed plate limiting member to restrict the range of motion of the first fixed plate 312 and ensure that the elastic member 7 is always located between the first fixed plate 312 and the second fixed plate 322.

[0037] In the coil lifting device of this embodiment, see Figure 3-4The fixing plate limiting component includes a movable groove 323, which is formed on the connecting component 32. A first fixing plate 312 passes through the movable groove 323 and is slidably connected to the movable groove 323 along the height direction. A limiting pin 61 is installed at the end of the first fixing plate 312 away from the connecting rod 311. In this way, the movable groove 323 is formed on the connecting component 32 to limit the range of motion of the first fixing plate 312. The first fixing plate 312 slides in the movable groove 323 along the height direction, and the movement of the connecting rod 311 and the first fixing plate 312 drives the movement and reset of the limiting pin 61.

[0038] In the coil lifting device of this embodiment, see Figure 1 The lifting beam 2 includes a mounting platform 24, which protrudes from the lifting beam 2 and has several adjustment slots 22. By setting the mounting platform 24 and having adjustment slots 22 on it, the spring balls can be in contact with the adjustment slots 22.

[0039] In the coil lifting device of this embodiment, see Figure 1 The coil lifting device includes an extension plate 8, which is perpendicular to the lifting beam 2 and fixedly connected to the lifting beam 2. Multiple limiting holes 62 are provided on the extension plate 8. By setting the extension plate 8, the extension direction of the limiting holes 62 is ensured to be consistent with the extension direction of the limiting pin, thereby achieving the limiting function of the limiting pin 61.

[0040] In the coil lifting device of this embodiment, see Figure 3 The lifting beam 2 includes a clearance groove 23, which is located between the mounting platform 24 and the extension plate 8. A slide rail 21 is installed inside the clearance groove 23. The clearance groove 23 is used to avoid the slider 321.

[0041] In the coil lifting device of this embodiment, see Figure 1 The lifting beams 2 consist of four beams, which are arranged in a circular array around the axis of the lifting body 1; the booms 3 consist of four booms, which are arranged one-to-one with the four lifting beams 2. In this way, by using multiple booms 3, the number of support points for the coil can be increased, ensuring that the coil is supported more stably and safely during the lifting process.
