Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and more specifically, to a hoisting fixture. Background Technology

[0002] In related technologies, chassis transfer fixtures can be used to lift and transfer chassis. However, the component used to connect the chassis transfer fixture to the chassis is usually a hook, which may detach during chassis transfer, causing product damage. Furthermore, the hook and the chassis transfer fixture body are connected by a chain; when the chassis transfer fixture is lowered to pick up and lower the chassis, the hook and chain may come into contact with parts of the chassis other than the clamping point, resulting in scratches on the chassis surface. Utility Model Content

[0003] This utility model provides a hoisting fixture that can improve the reliability of the hoisting and transportation process and reduce product quality problems caused by defects in the hoisting and transportation of the parts to be hoisted.

[0004] This utility model embodiment provides a lifting fixture, comprising: a frame having a mounting position for placing a component to be lifted; multiple sets of positioning pin assemblies disposed on the frame, each positioning pin assembly including a positioning pin located on one side of the mounting position in a horizontal direction and facing the mounting position, with the positioning pins of at least two sets of positioning pin assemblies located on different sides of the mounting position, and at least one set of positioning pin assemblies movably disposed on the frame to switch between a first state and a second state; in the first state, the positioning pins of the positioning pin assemblies are adapted to engage with the component to be lifted; in the second state, the positioning pins are separated from the component to be lifted; the positioning pin assemblies are configured to be locked to the frame in the first state.

[0005] In the above technical solution, by setting up a positioning pin assembly, the positioning pin of the positioning pin assembly can be inserted with the part to be lifted, and after insertion, the positioning pin assembly can be locked to the frame. This reduces the risk of the part to be lifted detaching from the lifting fixture and improves the reliability of the part's transfer process. Simultaneously, because the positioning pin assembly is located on the frame, it is less likely to come into contact with other parts of the part to be lifted when the lifting fixture is lowered to pick up or lower it. Therefore, it reduces the possibility of the part being scratched by the positioning pin assembly, better protects the part, and avoids product quality problems caused by defects resulting from clamping of the lifting fixture.

[0006] In some embodiments, the hoisting fixture further includes a positioning element, which includes a body and a protrusion. The body is disposed on the frame, and the protrusion is disposed on the lower side of the body. The protrusion is adapted to be inserted and engaged with the part to be hoisted. At least the body is used to support the part to be hoisted in the vertical direction.

[0007] In the above technical solution, by setting a positioning component, after the hoisting fixture is lowered, it first contacts the positioning component. The positioning component supports the part to be hoisted and is inserted into the part to be hoisted. Thus, the relative position of the part to be hoisted and the frame can be determined relatively quickly without repeatedly aligning the positioning pin and the insertion position on the part to be hoisted, which is conducive to realizing the rapid insertion of the positioning pin and the part to be hoisted.

[0008] In some embodiments, the body and the protrusion are formed with a fitting portion, which is deformable and adapted to fit with the part to be hoisted.

[0009] In the above technical solution, when the hoisting fixture lifts the part to be lifted, the mating part first comes into contact with the part to be lifted. The mating part can undergo a certain degree of deformation. In this way, the mating part is not easy to impact the surface of the part to be lifted, so the surface of the part to be lifted is not easily damaged or scratched by the hoisting fixture. When the positioning part moves relative to the part to be lifted, the positioning part is also not easy to scratch the surface of the part to be lifted.

[0010] In some embodiments, the bonding portion is made of polyurethane material.

[0011] In the above technical solution, when the bonding part of the polyurethane material part comes into contact with the part to be lifted, the possibility of the contact surface of the part to be lifted being scratched or damaged can be effectively reduced; at the same time, when the positioning part is supported on the part to be lifted, the positioning part itself will not undergo excessive deformation or large uncontrollable deformation.

[0012] In some embodiments, the positioning members are provided in multiples, and at least two of the positioning members have different shapes and / or sizes of the protrusions.

[0013] In the above technical solution, when a non-target component is mistakenly hoisted, it can be detected in time, thereby reducing the possibility of work errors.

[0014] In some embodiments, at least two of the locating pin assemblies are located on the same side of the mounting position and their movement paths are parallel to each other, and the locating pin assemblies are connected by connectors.

[0015] In the above technical solution, on the one hand, multiple positioning pin assemblies can be moved simultaneously by pushing the connecting piece, making the operation more convenient; on the other hand, the locking component or the driving component used to drive the positioning pin assemblies can be set on the connecting piece, that is, multiple positioning pin assemblies can share a locking component or driving component, which helps to reduce the production cost of hoisting tooling.

[0016] In some embodiments, the lifting fixture further includes a locking assembly comprising a locking ring and a locking hook, one of the locking ring and the locking hook being disposed on the frame, and the other of the locking ring and the locking hook being disposed on the connector. At least one of the locking ring and the locking hook is movable to switch between a tensioned state and a disengaged state. The locking ring and the locking hook are tensioned to lock the positioning pin assembly to the frame, and the locking ring is disengaged from the locking hook to release the positioning pin assembly.

[0017] In the above technical solution, the locking of the positioning pin assembly is achieved by using a combination of locking hook and locking ring, which facilitates the quick locking and unlocking of the positioning pin assembly, is convenient to use, and has low operating costs.

[0018] In some embodiments, the hoisting fixture further includes a limiting component, which includes a bracket and a limiting pin. The bracket is disposed on the frame and has a first connecting hole. The connecting member has a second connecting hole. The limiting pin is used to pass through the first connecting hole and the second connecting hole at least in the second state to limit the positioning pin assembly.

[0019] In the above technical solution, by setting a limiting component, the limiting component can limit the connecting part, and then limit the positioning pin component, so as to avoid uncontrollable displacement of the positioning pin component in the second state and reduce the risk of accidental collision between the part to be hoisted and the positioning pin component.

[0020] In some embodiments, there are two connectors, one of which has a handrail on the side facing away from the other connector.

[0021] In the above technical solution, two operators can control the position of the hoisting fixture through two handrails respectively. When the hoisting fixture is picking up and putting down the part to be hoisted, it is convenient to adjust the position and posture of the hoisting fixture. At the same time, it is convenient to hold the hoisting fixture during the transportation of the part to be hoisted, thus reducing safety hazards.

[0022] In some embodiments, the positioning pin assembly includes a slider, the positioning pin is disposed on the slider, the frame includes a slide rail, and the slider slides in cooperation with the slide rail so that the positioning pin assembly is translatably disposed on the frame.

[0023] In the above technical solution, the positioning pin assembly can be used for lifting components of various sizes, demonstrating good versatility. Furthermore, during movement, the positioning pin assembly is less likely to accidentally collide with the component, reducing the possibility of scratches. In addition, the use of a sliding rail and slider allows the slider to move quickly to the desired position with manual pushing, making operation smoother and more convenient.

[0024] In some embodiments, the frame includes two first beams and two second beams, the two first beams being connected between the two second beams at a distance, the first beams and the second beams intersecting, and a plurality of connecting beams connecting the two first beams, the connecting beams being connected to lifting rings via connecting plates.

[0025] In the above technical solution, the frame structure is simple and has good structural stability. Attached Figure Description

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "attachment," and "attachment" should be interpreted broadly.

[0049] In this utility model, "multiple" refers to two or more (including two).

[0050] In related technologies, chassis transfer fixtures can be used to lift and transfer chassis. However, the component used to connect the chassis to the chassis transfer fixture is usually a hook, which may detach during chassis transfer, causing product damage. Furthermore, the hook and fixture body are connected by a chain; when the fixture is lowered to pick up and lower the chassis, the hook and chain may come into contact with parts of the chassis other than the clamping point, resulting in scratches on the chassis surface.

[0051] In view of this, this application provides a lifting fixture. By setting a positioning pin assembly, the positioning pin of the positioning pin assembly can be inserted with the part to be lifted, and after insertion, the positioning pin assembly can be locked to the frame. This reduces the risk of the part to be lifted detaching from the lifting fixture and improves the reliability of the part's transfer process. Simultaneously, since the positioning pin assembly is located on the frame, it is less likely to come into contact with other parts of the part to be lifted when the lifting fixture is lowered to pick up or lower it. Therefore, the possibility of the part being scratched by the positioning pin assembly is reduced, better protecting the part and avoiding product quality problems caused by defects resulting from clamping of the lifting fixture.

[0052] The lifting fixtures provided in this application can be used to lift battery devices, integrated charging equipment chassis, etc., but are not limited to these.

[0053] For ease of explanation, please refer to the following examples. Figure 1 and Figure 2 , Figure 1 A schematic diagram of the bottom structure of the lifting fixture 100 provided in some embodiments of this application; Figure 2 A side view of a lifting fixture 100 provided for some embodiments of this application.

[0054] The lifting fixture 100 includes a frame 10 and multiple sets of positioning pin assemblies 20. The frame 10 has mounting positions for placing the part to be lifted. The multiple sets of positioning pin assemblies 20 are disposed on the frame 10. Each positioning pin assembly 20 includes a positioning pin 201, which is located on one side of the mounting position in the horizontal direction and faces the mounting position. The positioning pins 201 of at least two sets of positioning pin assemblies 20 are located on different sides of the mounting position. At least one set of positioning pin assemblies 20 is movably disposed on the frame 10 to switch between a first state and a second state. In the first state, the positioning pins 201 of the positioning pin assembly 20 are adapted to be inserted into the part to be lifted. In the second state, the positioning pins 201 are separated from the part to be lifted. The positioning pin assembly 20 is configured to be locked to the frame 10 in the first state to achieve horizontal and vertical positioning of the part to be lifted.

[0055] For example, the frame 10 includes multiple beams connected in a certain way, thereby giving the frame 10 high structural strength, making it less prone to deformation, and also making it relatively lightweight. The frame 10 is used to provide an installation position for the positioning pin assembly 20. The frame 10 has an installation position, which refers to the space on one side of the frame 10 used to place the part to be lifted. That is, according to the design, when the lifting fixture 100 lifts the part to be lifted, the part to be lifted will be located in a certain spatial position on one side of the frame 10, and this spatial position is the installation position.

[0056] For example, some of the positioning pin components 20 may be directly fixed to the frame 10, while others may be movably disposed on the frame 10. Alternatively, all of the positioning pin components 20 may be movably disposed on the frame 10.

[0057] The positioning pin assembly 20 is movably disposed on the frame 10. For example, the positioning pin assembly 20 is rotatably disposed on the frame 10 so that the position of the positioning pin 201 can change during rotation. For example, in the first state, the positioning pin 201 faces the horizontal direction, and in the second state, the positioning pin 201 faces the vertical direction. Alternatively, the positioning pin assembly 20 is translatably disposed on the frame 10 so that the position of the positioning pin 201 can change during translation.

[0058] The locating pins 201 of the multiple sets of locating pin assemblies 20 can be parallel to each other or intersect each other. In the first state, the locating pins 201 can be horizontal, or they can be at a set angle to the horizontal direction, with the set angle being less than 90 degrees, so that the part to be lifted can be supported by the locating pins 201.

[0059] The locating pin assembly 20 includes a locating pin 201 located on one side of the mounting position in the horizontal direction and facing the mounting position. The locating pins 201 of at least two sets of locating pin assemblies 20 are located on different sides of the mounting position so as to secure the part to be hoisted to the frame 10.

[0060] The positioning pin 201 of the positioning pin assembly 20 is adapted to be inserted into the part to be lifted. The position of the part to be lifted that is adapted to be inserted into the positioning pin 201 can be adapted to the size of the positioning pin 201. That is, the positioning pin 201 and the part to be lifted are inserted into each other, for example, with a clearance fit; or, the size of the part to be lifted that is adapted to be inserted into the positioning pin 201 can also be larger than the positioning pin 201.

[0061] Compared to related technologies that use clamping to fix the part to be lifted, in this application, the positioning pin 201 is inserted into the part to be lifted. On the one hand, by using the insertion method, the positioning pin 201 does not need to apply excessive clamping force to the part to be lifted, which helps to reduce the possibility of the lifting fixture 100 scratching or damaging the surface of the part to be lifted during the lifting and transportation process; on the other hand, by using the insertion method, the part to be lifted is not easy to fall off the lifting fixture 100, and the lifting stability is good.

[0062] The positioning pin assembly 20 is configured to be locked to the frame 10 in the first state. That is, the positioning pin 201 of the positioning pin assembly 20 can be inserted with the part to be lifted, and after insertion, the positioning pin assembly 20 can be locked to the frame 10. This reduces the risk of the part to be lifted detaching from the lifting fixture 100 and helps to improve the reliability of the transfer process of the part to be lifted.

[0063] Meanwhile, since the positioning pin assembly 20 is set on the frame 10, the position controllability of both the positioning pin assembly 20 and the frame 10 is good. Therefore, when the hoisting fixture 100 lowers to pick up and place the part to be hoisted, the positioning pin assembly 20 is unlikely to come into contact with other parts of the part to be hoisted. Thus, the possibility of the part to be hoisted being scratched by the positioning pin assembly 20 can be reduced, and the part to be hoisted can be better protected, avoiding product quality problems caused by defects in hoisting.

[0064] In the second state, the positioning pin 201 is separated from the part to be lifted. That is, in the second state, the positioning pin 201 and the part to be lifted are separated by a distance to avoid collision and interference between the positioning pin 201 and the part to be lifted when the lifting fixture 100 is separated from the part to be lifted.

[0065] Figure 3 This is a schematic diagram illustrating the structure of multiple positioning elements 30 provided in some embodiments of this application. Reference can be made to some embodiments of this application. Figure 1 and Figure 3 The hoisting fixture 100 also includes a positioning component 30, which includes a main body 301 and a protrusion 302. The main body 301 is located on the frame 10, and the protrusion 302 is located on the lower side of the main body 301. The protrusion 302 is adapted to be inserted and engaged with the part to be hoisted. At least the main body 301 is used to support the part to be hoisted in the vertical direction.

[0066] Specifically, only the main body 301 can be supported on the part to be lifted; or both the main body 301 and the protrusion 302 can be supported on the part to be lifted. When using the lifting fixture 100, firstly, the lifting fixture 100 is lowered until the positioning part 30 contacts the part to be lifted, then the position of the positioning pin assembly 20 is moved so that the positioning pin 201 is engaged with the part to be lifted, then the position of the positioning pin assembly 20 is locked, and finally the lifting fixture 100 and the part to be lifted are lifted and moved to realize the lifting and transfer of the part to be lifted.

[0067] In the above technical solution, by setting the positioning component 30, after the lifting fixture 100 descends, it first contacts the positioning component 30. The positioning component 30 supports the part to be lifted and is inserted into the part to be lifted. Therefore, the relative position of the part to be lifted and the frame 10 can be determined relatively quickly without repeatedly aligning the positioning pin 201 with the insertion position on the part to be lifted, which is beneficial for achieving rapid insertion of the positioning pin 201 and the part to be lifted. Furthermore, the part to be lifted abuts against the positioning component 30, thus the contact area between the part to be lifted and the lifting fixture 100 is small, which helps reduce the risk of the part to be lifted being scratched.

[0068] According to some embodiments of this application, reference can be made to Figure 1 The main body 301 and the protrusion 302 are formed with a fitting part 303, which is deformable and suitable for fitting with the part to be hoisted.

[0069] For example, the fitting portion 303 can deform to a certain extent, but the deformation will not be too large, so that when the positioning member 30 is supported on the part to be lifted, the positioning pin 201 and the insertion position on the part to be lifted can be aligned. For example, the main body 301 and the protrusion 302 are deformable as a whole, and the position of the main body 301 and the protrusion 302 for fitting with the part to be lifted is formed as the fitting portion 303.

[0070] When the hoisting fixture 100 hoists the part to be hoisted, the fitting part 303 first comes into contact with the part to be hoisted. The fitting part 303 can undergo a certain degree of deformation. In this way, the fitting part 303 is not likely to impact the surface of the part to be hoisted, so the surface of the part to be hoisted is not easily damaged or scratched by the hoisting fixture 100. When the positioning part 30 moves relative to the part to be hoisted, the positioning part 30 is also not likely to scratch the surface of the part to be hoisted.

[0071] For example, the fitting part 303 is soft and the surface of the fitting part 303 is smooth. In this way, on the one hand, when the positioning member 30 moves relative to the part to be lifted, the positioning member 30 is less likely to scratch the surface of the part to be lifted.

[0072] According to some embodiments of this application, the bonding portion 303 is made of polyurethane material.

[0073] For example, both the body 301 and the protrusion 302 are made of polyurethane. For example, the portions of the body 301 and the protrusion 302 that come into contact with the part to be lifted are made of polyurethane.

[0074] When the bonding part 303 of the polyurethane material part comes into contact with the part to be lifted, the possibility of the contact surface of the part to be lifted being scratched or damaged can be effectively reduced; at the same time, when the positioning part 30 is supported on the part to be lifted, the positioning part 30 itself will not undergo excessive deformation or large uncontrollable deformation.

[0075] According to some embodiments of this application, the positioning member 30 is provided in multiple forms, and at least two positioning members 30 have different shapes of protrusions 302.

[0076] According to some embodiments of this application, the positioning member 30 is provided in multiple forms, and the protrusions 302 of at least two positioning members 30 are of different sizes.

[0077] According to some embodiments of this application, the positioning member 30 is provided in multiple forms, and at least two positioning members 30 have protrusions 302 with different shapes and sizes.

[0078] For example, the multiple positioning elements 30 adopt a contour-following design, that is, the shape of the positioning element 30 is adapted to the shape of the insertion position of the part to be lifted for insertion with the positioning element 30.

[0079] For example, the protrusion 302 can be adapted to plug into the part to be lifted. For example, refer to Figure 1 and Figure 3 There may be four positioning members 30, and the shape and size of the protrusions 302 of the four positioning members 30 are different.

[0080] In some embodiments, the distance between the positioning elements 30 may also be different for the lifting fixture 100 used to lift different components. Specifically, the positioning elements 30 can be bolted to the frame 10 for easy disassembly and replacement.

[0081] Multiple positioning elements 30 are provided so that the frame 10 can be stably supported on the part to be hoisted, thereby reducing the workload and difficulty of operation.

[0082] It should be noted that different parts to be lifted have different shapes, sizes, and structures. For multiple positioning parts 30 of a lifting fixture 100, different protrusions 302 of the positioning parts 30 can be well fitted and inserted into the structure of a certain type of part to be lifted, but cannot be well fitted and inserted into other types of parts to be lifted. Therefore, when an incorrect part to be lifted is incorrectly lifted, it can be detected in time, reducing the possibility of work errors.

[0083] Figure 4This is a schematic diagram illustrating the structure of multiple locating pin assemblies 20 connected by connectors 40, as provided in some embodiments of this application. Reference can be made to some embodiments of this application. Figure 4 At least two locating pin assemblies 20 are located on the same side of the mounting position and their movement paths are parallel to each other. The locating pin assemblies 20 are connected by connectors 40.

[0084] For example, one can refer to Figure 1 Two locating pin assemblies 20 are located on one side of the mounting position and connected by connector 40, and two other locating pin assemblies 20 are located on the other side of the mounting position and connected by connector 40.

[0085] In the above technical solution, the positioning pin assemblies 20 that move in the same direction can be connected to each other through the connector 40. In this way, on the one hand, multiple positioning pin assemblies 20 can be moved simultaneously by pushing the connector 40, making the operation more convenient. On the other hand, the locking component 50 or the driving component for driving the positioning pin assemblies 20 can be set on the connector 40, that is, multiple positioning pin assemblies 20 can share a locking component 50 or a driving component, which helps to reduce the production cost of the hoisting fixture 100.

[0086] According to some embodiments of this application, reference can be made to Figure 1 and Figure 5 The hoisting fixture 100 also includes a locking assembly 50, which includes a locking ring 501 and a locking hook 502. One of the locking ring 501 and the locking hook 502 is located on the frame 10, and the other of the locking ring 501 and the locking hook 502 is located on the connector 40. At least one of the locking ring 501 and the locking hook 502 is movable so that the locking ring 501 and the locking hook 502 can switch between a tensioned state and a disengaged state. The locking ring 501 and the locking hook 502 are tensioned to lock the positioning pin assembly 20 to the frame 10, and the locking ring 501 and the locking hook 502 are disengaged to release the positioning pin assembly 20.

[0087] For example, one can refer to Figure 5 , Figure 5This is a schematic diagram of the structure of a locking component 50 provided in some embodiments of this application. A locking hook 502 is disposed on the frame 10. The locking component 50 includes a locking operation mechanism, which includes a mounting base 503, a rotating handle 504, and a locking ring 501. The rotating handle 504 includes a first part 505, a second part 506, and a third part 507. The second part 506 is connected between the first part 505 and the third part 507. The length direction of the first part 505 is consistent with the length direction of the third part 507. One end of the first part 505 is connected to the second part 506. One end of the first part 505 is rotatably mounted on the mounting base 503 via a rotating shaft 508. The other end of the first part 505 is located on the side away from the locking hook 502 and is connected to the locking ring 501. The third part 507 forms a handrail portion. In use, grip the armrest and rotate it away from the locking hook 502. This allows the third part 507 to rotate the first part 505 via the second part 506. The first part 505 then rotates the locking ring 501 around its axis, thus tightening the locking ring 501 with the locking hook 502. Alternatively, grip the armrest and rotate it closer to the locking hook 502. This allows the third part 507 to rotate the first part 505 via the second part 506. The first part 505 then rotates the locking ring 501 around its axis, thus separating the locking ring 501 from the locking hook 502.

[0088] For example, the locking ring 501 or locking hook 502 provided on the frame 10 can be directly provided on the frame 10, or it can be additionally provided on the frame 10 by means of a support frame.

[0089] In the above technical solution, the locking hook 502 and the locking ring 501 are used in combination to lock the positioning pin assembly 20, which is conducive to the quick locking and unlocking of the positioning pin assembly 20, and is convenient and low in cost.

[0090] In some embodiments, the use of the positioning pin assembly 20 and the locking assembly 50 in combination helps to ensure that the component to be lifted, such as the power bank chassis, is locked in all directions, eliminating various hidden dangers caused by insecure fixing during the transportation of the component to be lifted. This meets the requirements for fast, efficient and safe lifting of the power bank chassis, improves the convenience of operation, and reduces the risk of scratches and falling of the component to be lifted.

[0091] According to some embodiments of this application, reference can be made to Figure 1The hoisting fixture 100 also includes a limiting component 60, which includes a bracket 601 and a limiting pin 602. The bracket 601 is disposed on the frame 10 and has a first connecting hole 6011. The connector 40 has a second connecting hole 401. The limiting pin 602 is used at least in the second state to pass through the first connecting hole 6011 and the second connecting hole 401 to limit the positioning pin assembly 20.

[0092] Specifically, both the first connecting hole 6011 and the second connecting hole 401 extend in the vertical direction.

[0093] In other words, the limiting pin 602 is used to be inserted from top to bottom into the first connecting hole 6011 and the second connecting hole 401 when the positioning pin 201 and the part to be hoisted are separated. For example, multiple first connecting holes 6011 can be provided, so that the positioning pin assembly 20 can be fixed in multiple positions as needed. For example, the positioning pin assembly 20 can be limited to a certain position nearby, or it can also be used to further lock the position of the positioning pin assembly 20 in the first state, that is, when the positioning pin assembly 20 is locked by the locking component 50, so as to achieve redundant locking.

[0094] In the above technical solution, by setting the limiting component 60, the limiting component 60 can limit the connecting piece 40, and then limit the positioning pin assembly 20, so as to avoid the positioning pin assembly 20 in the second state from uncontrollable displacement and reduce the risk of accidental collision between the part to be hoisted and the positioning pin assembly 20.

[0095] According to some embodiments of this application, reference can be made to Figure 1 The connector 40 is equipped with a handrail 402.

[0096] For example, each connector 40 is provided with a handrail 402. See, for instance, [reference needed]. Figure 1 Two connecting parts 40 are provided, and the two connecting parts 40 are arranged opposite each other at a distance along the moving direction of the lifting fixture 100. Handrails 402 are provided on the side of the connecting parts 40 facing away from the other connecting part 40. In this way, the position of the lifting fixture 100 can be controlled by the two handrails 402 respectively. When the lifting fixture 100 is picking up and putting down the part to be lifted, it is convenient to adjust the position and posture of the lifting fixture 100. At the same time, it is convenient to hold the lifting fixture 100 during the transportation of the part to be lifted, reducing safety hazards.

[0097] According to some embodiments of this application, reference can be made to Figure 4 The positioning pin assembly 20 includes a slider 701, and the positioning pin 201 is disposed on the slider 701. The frame 10 includes a slide rail 702, and the slider 701 and the slide rail 702 are slidably engaged so that the positioning pin assembly 20 can be translatably disposed on the frame 10.

[0098] Specifically, the slider 701 is slidably engaged with the slide rail 702 to prevent the slider 701 from falling off the slide rail 702 in a direction perpendicular to its own movement. For example, the slide rail 702 is provided with limit blocks at both ends, which are used to limit the extreme position of the slider 701 along the slide rail 702 and prevent the slider 701 from disengaging from the slide rail 702.

[0099] In the above technical solution, the positioning pin assembly 20 can be used for lifting components of various sizes, exhibiting good versatility. Simultaneously, during movement, the positioning pin assembly 20 is less likely to accidentally collide with the component, reducing the possibility of the component being scratched by the positioning pin 201. Furthermore, by employing the sliding rail 702 and the slider 701 in conjunction, the slider 701 can be quickly moved to the desired position under manual pushing, making operation smoother and more convenient.

[0100] According to some embodiments of this application, reference can be made to Figure 1 The frame 10 includes two first beams 101 and two second beams 102. The two first beams 101 are connected between the two second beams 102 at intervals. The first beams 101 and the second beams 102 intersect. Multiple connecting beams 103 connect the two first beams 101. The connecting beams 103 are connected to lifting rings 104 through connecting plates 105. External lifting equipment can lift the lifting fixture 100 through the lifting rings 104.

[0101] For example, the slide rail 702 and the positioning element 30 are both provided on the second beam 102, the bracket 601 is provided on the first beam 101, the locking hook 502 is provided on the first beam 101 through the support frame, and the locking operation mechanism is provided on the connector 40.

[0102] In the above technical solution, frame 10 has a simple structure and good structural stability.

[0103] In some embodiments, in order to further increase the connection stability between the first beam 101 and the second beam 102, reinforcing plates can be provided on both sides of the connection position of the first beam 101 and the second beam 102, and the reinforcing plates connect the first beam 101 and the second beam 102.
