Description

Technical Field

[0001] This utility model relates to the field of hoisting and transportation technology, and in particular to a hoisting tool. Background Technology

[0002] Equipment hoisting is a crucial step in equipment handling and installation, especially for large or precision equipment, where its safety directly impacts the safety of the equipment itself and the operators. In hoisting operations, the rational design of lifting points is paramount: small equipment typically lacks pre-designed lifting points, while large equipment requires specific lifting positions, calculated stress points, and pre-installed lifting rings and other structures during the design phase to ensure hoisting stability. For non-standardized equipment or modular components of complete sets of equipment, the configuration, weight, and shape of their accessories may vary. If the lifting tools (such as ropes and slings) interfere with the precision components of the equipment during hoisting, it may lead to equipment damage or project delays. Therefore, designing dedicated hoisting fixtures for critical equipment is an effective means to improve safety and efficiency.

[0003] Currently, conventional hoisting methods mainly rely on the direct connection between general-purpose lifting tools (such as wire ropes and braided slings) and pre-set lifting points on the equipment. For vertical structures or equipment with a high center of gravity (such as large vacuum coating chambers), multi-point suspension or a balance beam structure is usually used to distribute the load. In addition, in some scenarios, the length or position of the lifting ropes is manually adjusted to match the center of gravity of the equipment. For example, after hoisting, the tension of the ropes is observed and repeatedly corrected to avoid skewing.

[0004] However, existing hoisting methods have the following shortcomings: First, high risk of damage: hoisting ropes or lifting tools are prone to collision with exposed precision instruments and valuable components of the equipment during operation, especially for equipment with sensitive components (such as coating cavities), even slight contact may lead to significant damage; Second, low efficiency: relying on manual adjustment of hoisting ropes (such as the unpredictable elongation of braided slings and the difficulty in straightening bent wire ropes), multiple trial hoists are required to calibrate the center of gravity, which is time-consuming, labor-intensive, and increases safety hazards due to repetitive operations; Third, insufficient safety assurance: traditional lifting tools lack redundant design, and if a single connection fails or the center of gravity suddenly shifts, it may cause the equipment to tip over or fall, resulting in weak risk control capabilities. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a hoisting fixture that aims to achieve multiple hoisting protection functions through multiple rigid connection mechanisms.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A hoisting fixture includes a hoist, a first rigid connector, a base, and a second rigid connector. The hoist has at least one set of hoisting points. The first rigid connector is disposed on the hoist and is used to detachably connect to the upper part of the object being hoisted. The base is used to support the lower part of the object being hoisted. Multiple sets of the second rigid connector are provided, and the multiple sets of the second rigid connector are arranged around the object being hoisted on the base. One end of the second rigid connector is connected to the hoist, and the other end of the second rigid connector is detachably connected to the base.

[0007] In addition, the hoisting fixture described above according to this utility model may also have the following additional technical features: Furthermore, the first rigid connector includes a first connecting seat, a first lifting ring, a first pin, and a first locking member. The first connecting seat is disposed on the hanger and has a first connecting arm disposed opposite to it. The first connecting arm has a first pin hole. The first lifting ring is disposed on the object being lifted and is located between the two first connecting arms. The first pin passes through the two first pin holes and the first lifting ring to connect the first lifting ring and the first connecting seat. The first locking member is disposed on the first pin and is used to lock the first pin.

[0008] Furthermore, multiple sets of the first rigid connector are provided at circumferential intervals along the top of the hoisted object.

[0009] Furthermore, the second rigid connector includes a linkage assembly, a second connecting seat, a second pin, and a second locking member. The linkage assembly is mounted on the hanger, the second connecting seat is connected to the linkage assembly, the second connecting seat has opposing second connecting arms, the second connecting arms have second pin holes, the second pin passes through the two second pin holes to support the base, and the second locking member is mounted on the second pin to lock the second pin. When the second locking member locks the second pin, a limiting area is formed between the second pin and the two second connecting arms to restrict the movement of the base.

[0010] Furthermore, the connecting rod assembly includes a straight rod and a rotating seat. One end of the straight rod is detachably mounted on the hanger. The rotating seat is connected to the straight rod, and both second connecting arms are mounted on the rotating seat. The straight rod is provided with a circumferential gap from the object being lifted on the base.

[0011] Furthermore, the rotating base is rotatably connected to the straight rod via a rotating shaft.

[0012] Furthermore, the hanger is provided with a hanger rod along its circumference, and the end of the straight rod away from the swivel is provided with an assembly hole, through which the straight rod is sleeved onto the hanger rod.

[0013] Furthermore, a third locking element is provided on the straight rod, which is used to lock the straight rod.

[0014] Furthermore, the second rigid connector also includes an adjustment component for adjusting the size of the limiting area. The adjustment component includes a bolt threaded onto the second connecting arm, and one end of the bolt can extend into the second pin hole.

[0015] Furthermore, the second rigid connector also includes a protective support block, which is slidably disposed within the second pin hole and located on the end of the bolt extending into the second pin hole.

[0016] The beneficial effects of this utility model include at least the following: through the synergistic action of the first rigid connector and the second rigid connector, a dual-path rigid connection structure is formed. The first rigid connector provides a rigid connection at the top, ensuring the stability of the main force path. Multiple sets of second rigid connectors are distributed around the base, so that even if the top connection fails, the base can still support the hoisted object, preventing it from falling or overturning. Moreover, since both the first and second rigid connectors are mechanically rigidly connected, the collision risk caused by the swing of traditional hoisting ropes is avoided, and there is no need to repeatedly adjust the length of the hoisting rope to match the center of gravity. In addition, both the first and second rigid connectors are detachable connections, which can achieve quick fixing, significantly shortening the installation time. Furthermore, the number of first and second rigid connectors can be increased or decreased to accommodate hoisted objects of different sizes, making it widely applicable. Attached Figure Description

[0021] Please refer to Figures 1 to 4This utility model provides a lifting fixture, including a lifting frame 100, a first rigid connector 200, a base 300, and a second rigid connector 400. Specifically, the lifting frame 100 has at least one set of lifting points 110, such as a fixed lifting plate at the center of the lifting frame 100, or multiple sets of lifting rings around the circumference of the lifting frame 100. The first rigid connector 200 is located on the lifting frame 100 and is detachably connected to the upper part of the object to be lifted 500. During lifting, the object 500 can be hung on the lifting frame 100 via the first rigid connector 200, and after lifting, the object 500 can be unloaded from the first rigid connector 200. The base 300 can support the lower part of the object 500 during lifting. Multiple sets of second rigid connectors 400 are provided, and these sets of second rigid connectors 400 are arranged around the suspended object 500 on the base 300. The upper end of the second rigid connector 400 is connected to the hanger 100, and the lower end of the second rigid connector 400 is detachably connected to the base 300. In this way, during hoisting, the suspended object 500 can be hung on the hanger 100 by the cooperation of the second rigid connector 400 and the base 300. After hoisting, the base 300 is first removed from the second rigid connector 400, and then the suspended object 500 is removed from the second rigid connector 400. Since the second rigid connector 400 is arranged around the suspended object 500 on the base 300, the second rigid connector 400 will not easily collide with the suspended object 500 when under force during hoisting, thus avoiding damage to the suspended object 500 due to collision or scratch.

[0022] In this embodiment, when the first rigid connector 200 fails, the object 500 will not immediately fall from the gantry 100. Instead, a connection between the base 300 and the gantry 100 can be established through the second rigid connector 400. This allows the base 300 to stably support the object 500. Furthermore, if some or all of the second rigid connectors 400 fail, a connection between the gantry 100 and other gantry 100s can be established through the first rigid connector 200, thus creating multiple layers of protection to prevent single-point failure from causing safety accidents and ensuring the safe transport of the object 500. Simultaneously, since the gantry 100 is detachably connected to the upper part of the object 500 via the first rigid connector 200, and the gantry 100 is detachably connected to the base 300 supporting the lower part of the object 500 via the second rigid connector 400, not only can rapid lifting be achieved, but the stability of the object 500 can also be effectively controlled, preventing swaying or tilting caused by a shift in the center of gravity during transport. In addition, for non-standard equipment (such as temporarily assembled modular components), the layout or quantity of the second rigid connector 400 can be adjusted, and in conjunction with the base 300, it can be flexibly adapted to hoisting objects 500 of different shapes and weights.

[0023] In some alternative embodiments, such as Figure 2As shown, the first rigid connector 200 includes a first connecting seat 210, a first lifting ring 220, a first pin 230, and a first locking element (not shown in the figures). Specifically, the first connecting seat 210 is disposed on the hanger 100. Optionally, the first connecting seat 210 is made of two opposing L-shaped steel frames, the vertical sides of which form opposing first connecting arms. The first connecting arms have first pin holes 211, and the two first pin holes 211 are aligned. The first lifting ring 220 is fixedly installed on the object being lifted 500, or the first lifting ring 220 is detachably installed on the object being lifted 500, and is located between the two first connecting arms. During lifting, the first pin 230 is simultaneously inserted into the two first pin holes 211 and the first lifting ring 220, thus establishing a mechanical connection between the first lifting ring 220 and the first connecting seat 210. Meanwhile, to prevent the first pin 230 from disengaging from the two first pin holes 211 and the first lifting ring 220, a first locking element is provided at one end of the first pin 230. When the first locking element is provided on the first pin 230, the end of the first pin 230 is locked, so that the first pin 230 is stably inserted into the two first pin holes 211 and the first lifting ring 220. Optionally, the first locking element is a nut, which is threaded onto the first pin 230. The locking and disengagement of the first pin 230 is achieved by screwing the first locking element. Alternatively, the first locking element is a pin, and a first pin hole 231 is provided on the first pin 230 accordingly.

[0024] In this embodiment, the first rigid connector 200 is composed of rigid components and is directly connected to the upper part of the hoisting object 500 to form a rigid connection without flexible deformation. Compared with traditional flexible slings, it can avoid the collision risk caused by the swing of the sling. Moreover, due to its rigid fixation, the length and posture of the first rigid connector 200 are determined after installation. Unlike flexible slings, it does not need to repeatedly adjust the elongation to match the center of gravity. It can directly achieve one-time accurate positioning, thereby improving hoisting efficiency.

[0025] In some optional embodiments, to further improve the safety and reliability of hoisting, such as Figure 1 As shown, multiple sets of first rigid connectors 200 are spaced circumferentially along the top of the hoisting object 500. This arrangement ensures that if some or all of the second rigid connectors 400 fail, a reliable connection can be established between the gantry 100 and the gantry 100 through the multiple first rigid connectors 200. Even if some of the first rigid connectors 200 fail, because they are rigid components, by maintaining the hoisting posture of the gantry 100 and appropriately setting the maximum connection strength of the first rigid connectors 200, one or several first rigid connectors 200 can lift the hoisting object 500. This forms multiple layers of protection, preventing single-point failure from causing safety accidents and ensuring the safe hoisting of the hoisting object 500.

[0026] In some alternative embodiments, such as Figure 3 , Figure 4 As shown, the second rigid connector 400 includes a connecting rod assembly 410, a second connecting seat 420, a second pin 430, and a second locking member (not shown in the figures). Specifically, the connecting rod assembly 410 is mounted on the hanger 100, and the second connecting seat 420 is connected to the connecting rod assembly 410. The second connecting seat 420 has opposing second connecting arms 421, and the second connecting arms 421 have second pin holes 4211, with the two second pin holes 4211 aligned in a straight line. During hoisting, the second pin 430 is inserted into the two second pin holes 4211, allowing the second pin 430 to support the base 300. Simultaneously, the two second connecting arms 421 can limit the base 300 from both sides, and the second pin 430 and the second connecting seat 420 can limit the base 300 from the top and bottom. Meanwhile, to prevent the second pin 430 from disengaging from the two second pin holes 4211, a second locking element is provided at one end of the second pin 430. When the second locking element is provided on the second pin 430, the end of the second pin 430 is locked, so that the second pin 430 is stably inserted into the two second pin holes 4211. Optionally, the second locking element is a nut, which is threaded onto the second pin 430. The second pin 430 is locked and disengaged by screwing on the second locking element. Alternatively, the second locking element is a pin, and a second pin hole 431 is provided on the second pin 430 accordingly.

[0027] In some alternative embodiments, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the linkage assembly 410 includes a straight rod 411 and a rotating seat 412. Specifically, one end of the straight rod 411 is detachably mounted on the hanger 100 to facilitate quick disassembly of the straight rod 411 after hoisting. The rotating seat 412 is connected to the straight rod 411, and both second connecting arms 421 are mounted on the rotating seat 412. In this embodiment, when the second pin 430 is inserted into the two second pin holes 4211, a closed limiting area is formed between the second pin 430, the two second connecting arms 421, and the rotating seat 412 to restrict the movement of the base 300. At this time, the second pin 430 supports the bottom of the base 300, while the two second connecting arms 421 can limit the sides of the base 300 from both sides, and the second pin 430 and the rotating seat 412 limit the upper and lower parts of the base 300 from the upper and lower directions. In addition, to prevent the straight rod 411 from colliding with or scratching the lower-lying object 500 during hoisting, a circumferential gap is provided between the straight rod 411 and the object 500 on the base 300.

[0028] In some alternative embodiments, such as Figure 4As shown, the rotatable base 412 is rotatably connected to the straight rod 411 via a rotating shaft 413. This configuration allows the rotatable base 412 to automatically rotate to adapt to the tilt angle of the contact surface of the base 300 when hoisting equipment of different sizes or shapes, ensuring a tight fit between the second connecting arm 421, the second pin 430, and the base 300 without the need for repeated manual adjustments. For example, if the base 300 undergoes slight deformation due to the weight of the equipment, the rotation of the rotatable base 412 can compensate for the angular deviation, avoiding stress concentration caused by rigid connections. Furthermore, before hoisting, the rotatable base 412 can freely rotate to a naturally drooping state, facilitating quick insertion of the second pin 430 through the bottom of the base 300 by operators. Compared to fixed connections, the rotating design reduces installation accuracy requirements, making it particularly suitable for rapid on-site assembly. In addition, during hoisting or movement, if the equipment sways slightly due to inertia, the rotation of the rotatable base 412 can buffer the instantaneous torque, preventing force transmission to the lifting frame 100 and thus improving stability.

[0029] In some alternative embodiments, to achieve the purpose of setting the circumferential clearance between the straight rod 411 and the lifting object 500 on the base 300, such as Figure 3 As shown, the hanger 100 has a lifting rod 120 extending outward along its circumference. The upper end of the straight rod 411 is provided with an assembly hole. During hoisting, the straight rod 411 is fitted onto the lifting rod 120 through the assembly hole. In this way, the hanger 100 can form two independent rigid connection paths through the straight rod 411 and the first rigid connector 200, thus forming multiple protections. Correspondingly, the base 300 is set as a large bearing surface, that is, the base 300 is designed as an extended bearing surface. The area of ​​the extended bearing surface is larger than the bottom projection of the hoisted object 500, so that the center of gravity of the hoisted object 500 is always within the support range of the base 300, to ensure support stability and prevent the hoisted object 500 from tipping over when placed on the base 300. The part of the lower end of the straight rod 411 that connects to the base 300 is located at the edge of the extended bearing surface.

[0030] In some alternative embodiments, to prevent the straight rod 411 from detaching from the boom 120, such as Figure 3 As shown, a third locking element 414 is provided on the straight rod 411. When the third locking element 414 is provided on the boom 120, the end of the straight rod 411 is locked, so that the straight rod 411 is stably sleeved on the boom 120. Optionally, the third locking element 414 is a nut, which is threaded onto the boom 120. The locking and unlocking of the straight rod 411 is achieved by turning the third locking element 414.

[0031] In some alternative embodiments, such as Figure 4As shown, the second rigid connector 400 also includes an adjustment component 600, which is used to adjust the size of the limiting area. Specifically, the second pin hole 4211 is configured as an elongated hole. The adjustment component 600 includes a bolt 610, which is threaded onto the second connecting arm 421. When the bolt 610 is tightened, the upper end of the bolt 610 can extend into the second pin hole 4211 or disengage from it. When the bolt 610 is tightened, the upper end of the bolt 610 supports the second pin shaft 430 upwards. By adjusting the length of the upper end of the bolt 610 extending into the second pin hole 4211, the position of the second pin shaft 430 can be changed. This changes the size of the closed limiting area formed between the second pin shaft 430, the two second connecting arms 421, and the rotating base 412, which restricts the movement of the base 300. This not only allows the straight rod 411 to exert tension on the base 300 by adjusting the bolt 610, but also allows for the adaptation of bases 300 of different sizes and specifications, thus improving the applicability of the equipment.

[0032] In this embodiment, before hoisting, the second pin hole 4211 in the second pin shaft 430 is inserted. At the beginning of the hoisting, after the first rigid connector 200 is subjected to the hoisting force, the adjusting bolt 610 causes the straight rod 411 to generate a pulling force on the base 300. The hoisting operation is carried out after both the first rigid connector 200 and the straight rod 411 are subjected to the lifting force.

[0033] In some alternative embodiments, such as Figure 4 As shown, the second rigid connector 400 also includes a protective support block 620. The support surface of the protective support block 620 is designed to be larger than the contact surface between the second pin 430 and the bolt 610. The protective support block 620 is slidably disposed in the second pin hole 4211, so that the protective support block 620 can move along the extension direction of the second pin hole 4211. At the same time, the protective support block 620 is fixedly installed on the upper end of the bolt 610. During hoisting, the protective support block 620 supports the second pin 430 upward.

[0034] In this embodiment, the length of the upper end of the bolt 610 extending into the second pin hole 4211 can be adjusted by tightening the bolt 610, thereby adjusting the position of the protective support block 620 within the second pin hole 4211. When the position of the protective support block 620 changes, the position of the second pin 430 located at the upper end of the protective support block 620 also changes. Since the contact area of ​​the protective support block 620 is larger than the contact surface between the second pin 430 and the bolt 610, the protective support block 620 can disperse local pressure, preventing deformation or wear of the second pin 430 due to concentrated loads. This is especially suitable for hoisting heavy equipment, extending the service life of critical components. Moreover, if the second pin 430 is accidentally bent, a portion of the larger support surface of the protective support block 620 may still contact the unbent portion of the second pin 430, thereby reducing the probability of further deformation of the second pin 430.

[0035] In some optional embodiments, in order to improve the stability of the protective support block 620 supporting the second pin 430, the protective support block 620 is provided with an arc surface (not shown in the figures) that fits against the outer peripheral surface of the second pin 430.
