Description

Technical Field

[0001] This application relates to the field of hoisting technology, and in particular to a support fixture. Background Technology

[0002] Support fixtures are devices used to connect and support items during hoisting, enabling the items to be hoisted to be connected to the hoisting equipment, thereby achieving the hoisting of the items. They are particularly suitable for the handling of heating equipment in the semiconductor heating field, such as the transportation of hot zones and the disassembly and assembly of furnace platforms.

[0003] Scaffolding fixtures typically consist of a cross-shaped support and a lifting chain. The lifting chain is connected to the object to be lifted, and the cross-shaped support supports the lifting chain and connects to the lifting equipment, thereby lifting the object. However, the structure of existing scaffolding fixtures is usually fixed, which means that the size and model of the fixture cannot be changed. One scaffolding fixture can only be used for one type of object to be lifted, resulting in low adaptability of the fixture for lifting operations.

[0004] Therefore, how to improve the adaptability of support fixtures for lifting is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this application is to provide a support fixture with high hoisting adaptability.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A support fixture is disclosed for lifting items. The fixture includes multiple lifting components, multiple supports, multiple connecting rods, an adjusting plate, and multiple fasteners. The lifting components are used to lift items, the supports are used to connect to lifting equipment, and the multiple supports are interconnected. Each connecting rod is movably connected to one support, and each connecting rod has a degree of freedom of movement along the extension direction of its corresponding support. Each connecting rod is connected to a lifting component. The adjusting plate is rotatably connected to the connections of the multiple supports. The adjusting plate has multiple arc-shaped holes, and each fastener passes through one arc-shaped hole and is connected to a corresponding connecting rod. Each arc-shaped hole has two ends, designated as a first end and a second end. During the movement of each fastener from the first end to the second end, the distance between the fastener and the axis of the adjusting plate gradually decreases, or the distance between the fastener and the axis of the adjusting plate gradually increases.

[0008] Furthermore, multiple arc-shaped holes are evenly distributed on the adjustment disk around the axis of the adjustment disk. The first end of each arc-shaped hole is spaced at the same distance from the axis of the adjustment disk, and the second end of each arc-shaped hole is spaced at the same distance from the axis of the adjustment disk.

[0009] Furthermore, each bracket has a receiving groove for accommodating the connecting rod, the opening of the receiving groove is located at the end of the bracket away from the adjustment plate, each bracket also has a sliding hole, each sliding hole communicates with the corresponding receiving groove, and each fastener passes through a corresponding sliding hole and is connected to a corresponding connecting rod.

[0010] Furthermore, along the extension direction of the bracket, the maximum distance between each sliding hole and the axis of the adjusting disc is greater than or equal to the maximum distance between the corresponding arc-shaped hole and the axis of the adjusting disc, and / or, the minimum distance between each sliding hole and the axis of the adjusting disc is less than or equal to the minimum distance between the corresponding arc-shaped hole and the axis of the adjusting disc.

[0011] Furthermore, the bracket fixture also includes a connector, with multiple brackets evenly arranged around the connector. The adjusting plate is rotatably connected to the connector. The connector has multiple connecting slots for connecting the brackets, and the opening of each connecting slot is located on the connector at the end away from the axis of the adjusting plate.

[0012] Furthermore, the support fixture also includes a lifting component for connecting the lifting equipment. The lifting component has an adjusting plate inserted through it and is rotatably connected to the connecting component. The adjusting plate is rotatably connected to the lifting component.

[0013] Furthermore, the lifting component includes a first shaft and a second shaft. The first shaft passes through an adjusting disc and is rotatably connected to a connecting member. One end of the second shaft is connected to the end of the first shaft furthest from the connecting member, and the other end of the second shaft is connected to the lifting equipment. The adjusting disc is rotatably connected to the first shaft.

[0014] Furthermore, the first shaft is provided with a first limiting part, which abuts against the lower surface of the connector, and the second shaft is provided with a second limiting part, which abuts against the upper surface of the adjusting disc when the second shaft and the first shaft are connected.

[0015] Furthermore, the lifting component includes a first shaft and an eye nut. The first shaft passes through an adjusting disc and is rotatably connected to a connecting member. The eye nut is connected to the end of the first shaft furthest from the connecting member and is also connected to the lifting equipment. The adjusting disc is rotatably connected to the first shaft.

[0016] Furthermore, a hook is provided at the end of the suspension component away from the connecting rod.

[0017] The aforementioned support fixture uses a rotating adjustment disc to allow the fasteners to slide within the arc-shaped hole, thereby moving the connecting rod along the extension direction of the corresponding bracket. This adjusts the length of the connecting rod and the corresponding bracket along the extension direction of the corresponding bracket, enabling the support fixture to connect and support items of different sizes and models to be hoisted, thus improving the hoisting adaptability of the support fixture.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0025] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The upper and lower positions are shown.

[0026] like Figure 1 and Figure 2As shown, this application provides a support fixture 100 for lifting items. The support fixture 100 includes multiple hanging components 11, multiple supports 12, multiple connecting rods 13, an adjusting plate 14, and multiple fasteners 15. The hanging components 11 are used for lifting items. The supports 12 are used to connect to lifting equipment, and multiple supports 12 are interconnected to form a lifting frame, which facilitates the support fixture 100 in supporting the items to be lifted. Each connecting rod 13 is movably connected to one support 12, and each connecting rod 13 is connected to one hanging component 11. The connecting rod 13 connects the hanging component 11 and the support 12, and each connecting rod 13 has a degree of freedom of movement along the extension direction of the corresponding support 12, so that each connecting rod 13 can move along the extension direction of the corresponding support 12, thereby adjusting the length of the connecting rod 13 and the corresponding support 12 along the extension direction of the corresponding support 12.

[0027] It should be noted that the support 12 is a rod-shaped structure, and the extension direction of the support 12 is the extension direction of the rod-shaped structure.

[0028] The adjusting disc 14 is rotatably connected to multiple supports 12. The adjusting disc 14 drives the connecting rod 13 to move along the extension direction of the corresponding support 12. Fasteners 15 connect the adjusting disc 14 and the connecting rod 13. Specifically, the adjusting disc 14 has multiple arc-shaped holes 141. Each fastener 15 passes through one arc-shaped hole 141 and is connected to a corresponding connecting rod 13. More specifically, the two ends of each arc-shaped hole 141 are defined as a first end 1411 and a second end 1412, respectively. As each fastener 15 moves from the first end 1411 to the second end 1412, the distance between the fastener 15 and the axis of the adjusting disc 14 gradually decreases, or the distance between the fastener 15 and the axis of the adjusting disc 14 gradually increases. With this configuration, by rotating the adjusting plate 14, the fastener 15 can move within the arc-shaped hole 141, thereby adjusting the distance between the fastener 15 and the axis of the adjusting plate 14. This, in turn, adjusts the distance between the connecting rod 13 connected to the fastener 15 and the axis of the adjusting plate 14, allowing the connecting rod 13 to move along the extension direction of the corresponding bracket 12. This, in turn, adjusts the total length of the connecting rod 13 and the corresponding bracket 12 along the extension direction of the corresponding bracket 12, enabling the bracket fixture 100 to adapt to different sizes and models of items to be hoisted, thus improving the hoisting adaptability of the bracket fixture 100.

[0029] Furthermore, when the support fixture 100 is not being used for hoisting operations, the length of the connecting rod 13 and the corresponding bracket 12 along the extension direction of the corresponding bracket 12 can be shortened by rotating the adjustment disc 14, thereby reducing the size of the support fixture 100 and improving its portability.

[0030] In some embodiments, multiple supports 12 can be fixed by welding, which helps to improve the connection stability between multiple supports 12, thereby improving the structural strength of the support fixture 100.

[0031] For example, when the adjusting disk 14 rotates in the first rotation direction, the fastener 15 can move from the first end 1411 to the second end 1412, and the distance between the fastener 15 and the axis of the adjusting disk 14 gradually increases.

[0032] When the adjusting plate 14 rotates in the first rotation direction, the distance between the fastener 15 and the axis of the adjusting plate 14 can be increased, thereby increasing the total length of the connecting rod 13 and the corresponding bracket 12 in the extension direction of the corresponding bracket 12, which is beneficial for the bracket fixture 100 to connect and lift large-sized items to be lifted.

[0033] When the adjusting plate 14 rotates in the second rotation direction, the distance between the fastener 15 and the axis of the adjusting plate 14 decreases, thereby reducing the total length of the connecting rod 13 and the corresponding bracket 12 along the extension direction of the corresponding bracket 12, which is beneficial for the bracket fixture 100 to connect and lift small-sized items to be lifted.

[0034] In summary, by rotating the adjustment disc 14, the position of the fastener 15 within the arc-shaped hole 141 can be adjusted, thereby adjusting the overall size of the bracket fixture 100. This allows the bracket fixture 100 to connect and lift items of different sizes, thus improving the lifting adaptability of the bracket fixture 100.

[0035] It should be noted that the first rotation direction and the second rotation direction are opposite rotation directions.

[0036] In some embodiments, the fastener 15 can be a bolt, which passes through an arc-shaped hole 141 and connects to a corresponding connecting rod 13. Tightening the bolt fixes the adjusting plate 14 to the corresponding connecting rod 13, thereby limiting the position of the corresponding connecting rod 13 and preventing it from sliding freely during hoisting, thus improving the hoisting stability of the support fixture 100. Loosening the bolt releases the fixation between the adjusting plate 14 and the corresponding connecting rod 13, allowing the adjusting plate 14 to rotate, which in turn facilitates adjusting the position of the fastener 15 within the arc-shaped hole 141, and consequently, adjusting the dimensions of the support fixture 100.

[0037] like Figure 2As shown, in one embodiment, multiple arc-shaped holes 141 are evenly distributed on the adjusting disk 14 around its axis. Specifically, the distance between the first end 1411 of each arc-shaped hole 141 and the axis of the adjusting disk 14 is consistent, and the distance between the second end 1412 of each arc-shaped hole 141 and the axis of the adjusting disk 14 is also consistent. This arrangement allows multiple connecting rods 13 connected to the multiple arc-shaped holes 141 to move synchronously, which helps to ensure that the distance between each hanging component 11 and the axis of the adjusting disk 14 along the extension direction of the corresponding bracket 12 remains consistent. This facilitates the connection and lifting of cylindrical objects of different diameters.

[0038] like Figure 3 As shown, in one embodiment, each bracket 12 has a receiving groove 121 for accommodating the connecting rod 13. The opening of the receiving groove 121 is located at the end of the bracket 12 opposite to the adjusting plate 14. With this arrangement, each connecting rod 13 is slidably connected to the corresponding bracket 12 through the receiving groove 121, and the receiving groove 121 can limit and guide the movement of the connecting rod 13, thereby improving the connection stability between each connecting rod 13 and the corresponding bracket 12, thus improving the connection strength between the connecting rod 13 and the corresponding bracket 12, and further improving the structural strength of the bracket fixture 100 to avoid deformation and damage to the bracket fixture 100.

[0039] Specifically, each bracket 12 is also provided with a sliding hole 122, which communicates with a corresponding receiving groove 121. Each fastener 15 passes through a corresponding sliding hole 122 and is connected to a corresponding connecting rod 13. This arrangement prevents the sliding hole 122 from interfering with the movement of the fastener 15, allowing the fastener 15 to adjust the position of the corresponding connecting rod 13 in conjunction with the rotation of the adjusting disc 14. This facilitates the adjustment of the dimensions of the bracket fixture 100, thereby improving its hoisting adaptability.

[0040] In one implementation, along the extending direction of the bracket 12, the maximum distance between each sliding hole 122 and the axis of the adjusting disk 14 is greater than or equal to the maximum distance between the corresponding arc-shaped hole 141 and the axis of the adjusting disk 14, and / or, the minimum distance between each sliding hole 122 and the axis of the adjusting disk 14 is less than or equal to the minimum distance between the corresponding arc-shaped hole 141 and the axis of the adjusting disk 14. With this configuration, during the movement of the fastener 15 in the arc-shaped hole 141, the sliding hole 122 can provide travel space for the fastener 15 to move on the bracket 12, thus avoiding interference between the fastener 15 and the bracket 12, preventing the fastener 15 from being unable to move within the arc-shaped hole 141. This also prevents the position of the fastener 15 from being unable to be adjusted when rotating the adjusting disk 14, and prevents the fastener 15 from being unable to drive the connecting rod 13 to move, thereby facilitating the dimensional adjustment of the bracket fixture 100.

[0041] In some embodiments, the support 12 is made of alloy steel, and the connecting rod 13 is made of stainless steel. Alloy steel has high strength, which improves the structural strength of the support 12 and thus the overall structural strength of the support fixture 100, enabling the support fixture 100 to lift heavier items. Furthermore, stainless steel is less expensive, which helps reduce the production cost of the support fixture 100.

[0042] In one embodiment, the bracket fixture 100 also includes a connector 16 for connecting multiple brackets 12. Specifically, the multiple brackets 12 are evenly arranged around the connector 16, and the adjusting plate 14 is rotatably connected to the connector 16. This arrangement allows the connection between the multiple brackets 12 to be achieved through the connector 16, which helps to improve the connection stability between the multiple brackets 12.

[0043] More specifically, the connector 16 has multiple connecting slots 161 for connecting the bracket 12. The opening of each connecting slot 161 is located at the end of the connector 16 away from the axis of the adjusting disc 14. This arrangement allows the connecting slots 161 to pre-position the bracket 12, facilitating the assembly of the bracket 12 and the connector 16, thereby improving the assembly efficiency of the bracket fixture 100. Furthermore, the connecting slots 161 can limit the position of the bracket 12, improving the positional accuracy of the bracket 12 connection and preventing misalignment of the bracket 12 and connector 16, which would render the bracket fixture 100 unusable and improve the assembly accuracy of the bracket 12 and connector 16. In some embodiments, the bracket 12 and the connecting slots 161 are fixed by welding.

[0044] In one implementation, the support fixture 100 also includes a lifting component 17 for connecting to the lifting equipment. Specifically, the lifting component 17 has an adjusting plate 14 passing through it and is rotatably connected to the connecting member 16, and the adjusting plate 14 is rotatably connected to the lifting component 17. With this configuration, during the lifting process of the lifting equipment using the support fixture 100 to lift the object, the lifting component 17 allows the support 12 to rotate relative to the lifting equipment, thereby allowing the object to be lifted to rotate relative to the lifting equipment. This facilitates adjusting the angle of the object to be lifted, avoiding angular interference between the lifting equipment and the object, which could prevent the object from being lifted and installed, thus improving the ease of lifting with the support fixture 100.

[0045] like Figure 3 and Figure 4As shown, in one embodiment, the lifting component 17 includes a first shaft 171 and a second shaft 172. The first shaft 171 passes through an adjusting plate 14 and is rotatably connected to a connecting member 16. One end of the second shaft 172 is connected to the end of the first shaft 171 away from the connecting member 16, and the other end of the second shaft 172 is connected to the lifting equipment. The adjusting plate 14 is rotatably connected to the first shaft 171. This configuration, with its separate structure of the first shaft 171 and the second shaft 172, improves the ease of assembly and disassembly of the lifting component 17, the connecting member 16, and the adjusting plate 14, thereby facilitating the assembly and disassembly of the support fixture 100 and improving its usability. Furthermore, it allows for the replacement of different models of the adjusting plate 14 and the connecting member 16 within the support fixture 100, enabling the support fixture 100 to accommodate a wider range of sizes and models of items to be lifted.

[0046] In some embodiments, a bearing 18 is mounted on the connector 16, and the connector 16 is connected to the first shaft 171 via the bearing 18 to facilitate relative rotation between the first shaft 171 and the connector 16.

[0047] In some embodiments, the first shaft 171 is provided with an internal thread and the second shaft 172 is provided with an external thread, so that the first shaft 171 and the second shaft 172 are connected by threads. The threaded connection allows the first shaft 171 and the second shaft 172 to be relatively fixed, and also facilitates the assembly and disassembly of the first shaft 171 and the second shaft 172.

[0048] In some embodiments, a connecting hole (not shown) is provided on the second shaft 172, and the hoisting equipment is connected to the hoisting component 17 through the connecting hole to realize the connection between the hoisting equipment and the support fixture 100.

[0049] In one embodiment, the first shaft 171 is provided with a first limiting part (not shown in the figure), which abuts against the lower surface of the connector 16 along the vertical direction of the bracket fixture 100. The second shaft 172 is provided with a second limiting part 1721, which abuts against the upper surface of the adjusting plate 14 when the second shaft 172 and the first shaft 171 are connected. With this configuration, the lower surface of the connector 16 can be limited by the first limiting part, and the upper surface of the adjusting plate 14 can be limited by the second limiting part 1721. This allows the connector 16 and the adjusting plate 14 to be limited along the vertical direction of the bracket fixture 100, preventing the adjusting plate 14 and the connector 16 from deflecting during hoisting, thereby improving the hoisting stability of the bracket fixture 100.

[0050] In another embodiment, the lifting component 17 includes a first shaft 171 and an eye nut. The first shaft 171 passes through an adjusting disc 14 and is rotatably connected to a connector 16. The eye nut is connected to the end of the first shaft 171 away from the connector 16 and is also connected to the lifting equipment. The adjusting disc 14 is rotatably connected to the first shaft 171. In some embodiments, the eye nut is threaded to the first shaft 171. This configuration eliminates the need for a connection hole in the eye nut, thus improving the ease of connection between the lifting component 17 and the lifting equipment.

[0051] like Figure 1 As shown, in one embodiment, a hook 111 is provided at the end of the hanging component 11 away from the connecting rod 13. The hook 111 is used to connect the hanging component 11 to the object to be lifted. In some embodiments, the hanging component 11 is a lifting chain, one end of which is bolted to the connecting rod 13 to facilitate the assembly and disassembly of the lifting chain and the connecting rod 13. The hook 111 is located at the end of the lifting chain away from the connecting rod 13, which facilitates the connection between the hanging component 11 and the object to be lifted, thereby improving the ease of connection between the support fixture 100 and the object to be lifted.
