Auxiliary lifting equipment for suspending and spraying steel structure space frame members

Abstract

This invention discloses a lifting device for suspending and spraying steel structure space frame members, including an outer frame that is correspondingly snapped into the interior of the space frame member. Multiple square and round rods are annularly arranged on the top surface of the outer frame, and clamps are movably fitted onto the surfaces of these rods, correspondingly snapping into the outer circumference of the space frame member. Multiple clips are arranged on the inner side of the outer frame. This invention utilizes an inner ring to move a cross plate up the surface of a central column. During the upward movement of the inner ring, multiple sliders separate due to the constraint of multiple wedge-shaped blocks. At this time, the sliders drive the outer ends of the clips to gradually move away from the vertical groove, and the outer ends of the clips gradually come into contact with the inner wall of the through groove of the space frame member. The pressure contact between the clips and the inner wall of the through groove of the space frame member facilitates precise installation of the lifting device and the space frame member. When spraying the surface of the space frame member using a spraying device, a comprehensive spraying operation can be completed on the surface of the space frame member in one operation.

Description

Technical Field

[0001] This invention belongs to the field of lifting equipment technology, and specifically relates to a lifting equipment for suspending and spraying steel structure space frame members. Background Technology

[0002] In the production and processing of steel structure space frame members, a significant number of space frame members undergo painting. Each member requires painting during processing, and this step plays a crucial role in product quality and assembly. Completing mass production tasks has a substantial impact on a company's production costs and time.

[0003] In typical spray painting methods, one or more components are placed on a reciprocating spraying platform for painting, depending on the product's spraying area. Because the components are constantly in contact with the platform, the painting process cannot be completed in one go, requiring secondary touch-ups. This affects the appearance and quality of the components, increases production costs, and reduces production efficiency.

[0004] Therefore, it is necessary to invent a lifting device for suspending and spraying steel structure space frame members to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a lifting device for suspending and spraying steel structure space frame members, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting device for suspending and spraying steel structure space frame members, comprising an outer frame, the outer frame being correspondingly snapped inside the space frame member, a plurality of square and round rods being arranged in a ring on the top surface of the outer frame, a clamp being movably sleeved on the surface of the square and round rods, and the clamp being correspondingly snapped on the outer circumference of the space frame member, a plurality of brackets being arranged on the inner side of the outer frame, the inner end of the bracket being connected to a movable structure for adjusting the position of the outer end of the bracket, and the bracket moving up and down inside the vertical groove of the outer frame using the movable structure, the outer end of the bracket penetrating the vertical groove and correspondingly snapping with the inner sidewall of the space frame member.

[0007] Furthermore, the bottom inner side of the outer frame is provided with multiple inner and outer ring edges, and an annular groove is formed between the inner and outer ring edges. A circular ring is provided inside the annular groove. The circular ring is correspondingly snapped onto the outside of the movable structure, and the outer circumference of the circular ring is spirally engaged with the inner sidewall of the outer ring edge. The circular ring rotates inside the annular groove, causing the movable structure to move up and down inside the outer frame.

[0008] Furthermore, the movable structure includes a central column located at the center of the inner side of the outer frame, with the bottom end of the central column correspondingly snapped into the center of the bottom ring. The bottom ring is snapped into the bottom of the outer frame using a ring groove and a vertical groove. A vertical rod is provided at the center of the inner ring edge, and a spring is sleeved on the surface of the vertical rod. A pressure plate is fixedly connected to the bottom end of the spring, and the top surface of the outer end of the pressure plate is correspondingly attached to the bottom surface of the bottom ring.

[0009] Furthermore, the movable structure also includes an inner ring. The inner wall of the ring is provided with an inner groove that rotatably engages with the inner ring. A cross plate is fixedly connected to the inner side of the inner ring. A cross-shaped through groove is provided at the center of the cross plate. The intermediate column passes through the cross-shaped through groove. Multiple wedge-shaped blocks corresponding to and matching the cross-shaped through groove are provided on the circumferential side of the intermediate column. The intermediate column is secured inside the cross-shaped through groove by the multiple wedge-shaped blocks. A rotating block is secured at the top of the intermediate column. The rotating block is screwed into the opening on the top surface of the outer frame.

[0010] Furthermore, the cross-shaped groove is provided with multiple sliders, the inner end of each slider is set as an arc surface, and the arc surface of the slider corresponds to and fits against the outer side of the wedge block. The outer side of the wedge block is inclined, and the area surrounded by the outer side of the top of the multiple wedge blocks is larger than the area surrounded by the outer side of the bottom of the multiple wedge blocks. The central column pushes the wedge block to move down inside the cross-shaped groove, and the multiple wedge blocks push the multiple sliders to separate from each other.

[0011] Furthermore, the bottom area of ​​the rotating block is larger than the area surrounded by the outer sides of the tops of the multiple wedge blocks, and the outer edges of the tops of the multiple wedge blocks are all inside the outer edges of the bottom surface of the rotating block.

[0012] Furthermore, the cross-shaped through groove includes four slots, and the slider is correspondingly snapped into the slot. Each side of the slot has a limiting groove, and a limiting rod is provided inside the limiting groove. Both ends of the slider are provided with protrusions that slide with the limiting groove, and the limiting rods pass through the protrusions. The slider slides with the protrusions on the surface of the limiting rods, and the outer side of the slider is fixedly connected to the cross-shaped through groove by an elastic element.

[0013] Furthermore, the inner ends of multiple card holders are connected to multiple sliders one by one. When the slider slides inside the cross-shaped through groove, the slider moves the card holder back and forth inside the vertical groove. The surface of the card holder is provided with a horizontal groove, and a sliding plate is provided inside the horizontal groove. Both ends of the sliding plate are connected to electric rotating wheels, and the surface of the electric rotating wheels is in contact with the bottom side of the ring. The sliding plate is correspondingly snapped into the inside of the ring groove.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. In this invention, when the inner ring of the circular ring drives the cross plate to move up on the surface of the middle column, multiple sliders separate from each other due to the constraint of multiple wedge blocks during the upward movement of the inner ring. At this time, the slider drives the outer end of the card holder to gradually move away from the vertical groove, and the outer end of the card holder gradually comes into contact with the inner wall of the through groove of the space frame member. By using the pressure contact between the card holder and the inner wall of the through groove of the space frame member, it is convenient to complete the precise installation of the lifting device and the space frame member. When the spraying device is used to spray the surface of the space frame member, the surface of the space frame member can be fully sprayed in one go.

[0016] 2. In this invention, when the inner ring of the circular ring drives the cross plate to move down on the surface of the middle column, the inner end of the slider is always in contact with the outer side of the wedge block under the elastic force of the elastic element. As the inner ring slides down, the sliders move closer to each other. At this time, the slider drives the outer end of the card holder to gradually approach the vertical groove. When the outer frame enters the interior of the space frame member, it can avoid collision damage between the outer end of the card holder and the inner wall of the through groove of the space frame member.

[0017] 3. When the bottom ring needs to be adjusted to different positions inside the ring groove, the middle column is pushed down inside the outer frame. The bottom end of the middle column pushes the bottom ring down inside the ring groove. During the downward movement, the bottom ring gradually pushes the pressure plate down synchronously on the surface of the vertical rod. During the downward movement of the pressure plate, the spring on the surface of the vertical rod is pulled. The elastic force of the spring makes the pressure plate push the bottom surface of the bottom ring upward. After the top of the middle column is limited inside the outer frame, the connection between the middle column and the outer frame is completed. By adjusting the spiral engagement between the rotating block and the top opening of the outer frame, the middle columns of different lengths can be easily installed inside the outer frame under the elastic force of the spring.

[0018] 4. This invention utilizes a rotating ring. When the ring rotates inside the groove, the spiral effect between the outer surface of the ring's circumference and the inner wall of the outer ring allows the ring to move up and down within the groove. Due to the groove's constraint on the ring, it can move smoothly up and down within the groove, preventing any deviation during its movement. During this movement, the ring can drive the movable structure to move synchronously within the outer frame, allowing adjustment of the position of the bracket inside the space frame members. This facilitates the use of the movable structure's bracket to engage with the space frame members at different depths within the through groove.

[0019] 5. In this invention, the bottom surface of the protruding strip connected to the outer end of the clamp is located at the bottom of the outer frame. After the clamp is locked onto the surface of the space frame member by the corresponding protruding strip, when the outer frame is pushed to move, the outer frame moves inside multiple clamps by the square and round rods until the outer frame is locked into the space frame member, thus completing the precise locking of the lifting device and the space frame member, and avoiding the outer frame of the lifting device from being unable to accurately lock onto the space frame member.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides a lifting device for suspending and spraying steel structure space frame members, such as... Figure 1As shown, the structure includes an outer frame 1, which is snapped into the interior of the space frame members. A plurality of square and round rods 2 are arranged in a ring on the top surface of the outer frame 1. A clamp 3 is movably sleeved on the surface of the square and round rods 2, and the clamp 3 is snapped into the outer circumference of the space frame members. A plurality of brackets 4 are arranged on the inner side of the outer frame 1. The inner end of the bracket 4 is connected to a movable structure that adjusts the position of the outer end of the bracket 4. The bracket 4 moves up and down inside the vertical groove 5 of the outer frame 1 using the movable structure. The outer end of the bracket 4 passes through the vertical groove 5 and is snapped into the inner wall of the space frame members. When the lifting device needs to be clipped into the steel structure's space frame member, the outer frame 1 is clipped into the through groove of the space frame member. At this time, the clamp 3 is pushed to slide on the surface of the square and round rod 2 until the clamp 3 is clipped into the outer circumference of the space frame member. When the outer frame 1 slides inside the through groove of the space frame member, due to the limiting cooperation between the clamp 3 and the square and round rod 2, the outer frame 1 can move smoothly inside the through groove of the space frame member, avoiding collision damage between the outer frame 1 and the inner wall of the space frame member during the movement. After the outer frame 1 moves into the space frame member, the clamp 4 is adjusted using the movable structure. When the clamp 4 moves up and down inside the vertical groove 5, it is convenient to make the outer end of the clamp 4 fit tightly against the inner wall of the space frame member, completing the connection between the lifting device and the space frame member.

[0028] When the bottom surface of the protrusion connected to the outer end of the clamp 3 is at the bottom of the bottom surface of the outer frame 1, the clamp 3 uses the protrusion to buckle onto the surface of the space frame member. When the outer frame 1 is pushed to move, the outer frame 1 uses the square and round rods 2 to move inside the multiple clamps 3 until the outer frame 1 is buckled into the space frame member, thus completing the precise buckling between the lifting device and the space frame member, and avoiding the outer frame 1 of the lifting device from failing to accurately buckle with the space frame member.

[0029] exist Figure 1 and Figure 2 In the middle, the bottom inner side of the outer frame 1 is provided with multiple inner ring edges and outer ring edges, and an annular groove 6 is formed between the inner ring edges and the outer ring edges. A circular ring 7 is provided inside the annular groove 6. The circular ring 7 is correspondingly snapped on the outside of the movable structure, and the outer circumference of the circular ring 7 is spirally engaged with the inner sidewall of the outer ring edge. The circular ring 7 rotates inside the annular groove 6, driving the movable structure to move up and down inside the outer frame 1. When it is necessary to adjust the position of the movable structure inside the outer frame 1, rotate the ring 7. When the ring 7 rotates inside the ring groove 6, the spiral effect between the outer circumference of the ring 7 and the inner sidewall of the outer ring edge allows the ring 7 to move up and down inside the ring groove 6. Due to the constraint of the ring groove 6 on the ring 7, the ring 7 can move up and down smoothly inside the ring groove 6, avoiding the ring 7 from shifting during the up and down movement. During the movement, the ring 7 can drive the movable structure to move synchronously inside the outer frame 1, which can adjust the position of the bracket 4 inside the space frame member, making it convenient for the lifting device to use the bracket 4 of the movable structure to fasten to different depths inside the through groove of the space frame member.

[0030] exist Figures 1-3In the middle, the movable structure includes a middle column 8, which is located at the center of the inner side of the outer frame 1, and the bottom end of the middle column 8 is correspondingly snapped at the center of the bottom ring 9. The bottom ring 9 is snapped at the bottom of the outer frame 1 by the ring groove 6 and the vertical groove 5. A vertical rod 10 is provided at the center of the inner ring edge, and a spring 11 is sleeved on the surface of the vertical rod 10. A pressure plate 12 is fixedly connected to the bottom end of the spring 11, and the top surface of the outer end of the pressure plate 12 is correspondingly attached to the bottom surface of the bottom ring 9. When it is necessary to adjust the position of the bottom ring 9 inside the ring groove 6, when the middle column 8 is pushed down inside the outer frame 1, the bottom end of the middle column 8 pushes the bottom ring 9 down inside the ring groove 6. During the downward movement, the bottom ring 9 gradually pushes the pressure plate 12 down synchronously on the surface of the vertical rod 10. During the downward movement, the pressure plate 12 pulls the spring 11 on the surface of the vertical rod 10. The elastic force of the spring 11 makes the pressure plate 12 push upward on the bottom surface of the bottom ring 9. After the top of the middle column 8 is limited inside the outer frame 1, the connection between the middle column 8 and the outer frame 1 is completed.

[0031] exist Figures 2-4 In the process, the movable structure also includes an inner ring 13. The inner wall of the circular ring 7 is provided with an inner groove that rotates with the inner ring 13. A cross plate 14 is fixedly connected to the inner side of the inner ring 13. A cross-shaped through groove 15 is provided at the center of the cross plate 14. The intermediate column 8 passes through the cross-shaped through groove 15. Multiple wedge blocks 16 corresponding to and matching the cross-shaped through groove 15 are provided on the circumferential side of the intermediate column 8. The intermediate column 8 is correspondingly snapped into the interior of the cross-shaped through groove 15 by the multiple wedge blocks 16. A rotating block 17 is correspondingly snapped into the top of the intermediate column 8. The rotating block 17 is screwed into the opening on the top surface of the outer frame 1. After the bottom end of the intermediate column 8 is correspondingly snapped into the center of the cross-shaped through groove 15, the wedge block 16 connected to the intermediate column 8 is correspondingly snapped into the cross-shaped through groove 15 of the cross plate 14. When the bottom end of the intermediate column 8 is limited to the bottom of the inner side of the outer frame 1 by the bottom ring 9, the top end of the intermediate column 8 is correspondingly connected to the top of the outer frame 1 by the rotating block 17. Since the inner ring 13 is correspondingly snapped into the wedge block 16 of the intermediate column 8 by the cross-shaped through groove 15, and the bracket 4 of the movable structure extends out of the vertical groove 5 of the outer frame 1, the inner ring 13 is prevented from rotating inside the outer frame 1.

[0032] When the ring 7 rotates on the surface of the inner ring 13 using the inner groove, the ring 7 can drive the inner ring 13 to move up and down synchronously inside the outer frame 1 when it moves up and down inside the ring groove 6, which makes it convenient to adjust the position of the bracket 4 inside the vertical groove 5.

[0033] exist Figures 2-4In this configuration, the bottom area of ​​the rotating block 17 is larger than the area surrounded by the outer surfaces of the tops of the multiple wedge blocks 16, and the outer edges of the tops of the multiple wedge blocks 16 are all inside the outer edges of the bottom surface of the rotating block 17. After the intermediate post 8 is correspondingly snapped into the interior of the outer frame 1 through the opening at the top of the outer frame 1, it is screwed into the top opening of the outer frame 1 by the rotating block 17. The rotating block 17 can limit the top of the intermediate post 8. The rotating block 17 cooperates with the bottom ring 9 to adjust the real-time position of the intermediate post 8 inside the outer frame 1. Multiple sliders 18 are provided inside the cross-shaped through groove 15. The inner end of the slider 18 is set as an arc surface, and the arc surface of the slider 18 corresponds to and fits against the outer surface of the wedge block 16. The outer surfaces of the wedge blocks 16 are inclined. The area surrounded by the outer surfaces of the tops of the multiple wedge blocks 16 is larger than the area surrounded by the outer surfaces of the bottoms of the multiple wedge blocks 16. The intermediate post 8 pushes the wedge blocks 16 to move down inside the cross-shaped through groove 15, and the multiple wedge blocks 16 push the multiple sliders 18 to separate from each other.

[0034] When the intermediate column 8 moves down inside the cross-shaped through groove 15 using the wedge block 16, the outer side of the wedge block 16 slides on the inner end surface of the slider 18, and the outer side of the inclined wedge block 16 pushes the slider 18 to move during the downward movement, and the multiple sliders 18 are separated from each other by the push of the multiple wedge blocks 16.

[0035] exist Figure 3 and Figure 4 In the cross-shaped through groove 15, there are four slots, and the slider 18 is correspondingly snapped into the slot. Each side of the slot is provided with a limiting groove, and a limiting rod 19 is provided inside the limiting groove. Both ends of the slider 18 are provided with protrusions that slide with the limiting grooves, and the limiting rod 19 passes through the protrusions. The slider 18 slides with the protrusions on the surface of the limiting rod 19, and the outer side of the slider 18 is fixedly connected to the cross-shaped through groove 15 by an elastic element 20. When it is necessary to adjust the position of slider 18 inside the slot, the intermediate post 8 slides up and down inside the cross-shaped through groove 15 using multiple wedge blocks 16. The intermediate post 8 slides on the inner end surface of multiple sliders 18 using multiple wedge blocks 16. The wedge blocks 16 move down, and the inclined outer surface of the wedge blocks 16 pushes the slider 18 to move inside the slot. When the slider 18 slides on the surface of the limiting rod 19 using the protrusion, it squeezes the elastic element 20. The wedge blocks 16 move up, and the elastic force of the elastic element 20 makes the inner end of the slider 18 always closely fit with the inclined outer surface of the wedge blocks 16, which facilitates the adjustment of the position of slider 18 inside the slot.

[0036] exist Figure 3 and Figure 4In this design, multiple card holders 4 are connected one-to-one with multiple sliders 18 on their inner sides. When the sliders 18 slide inside the cross-shaped through groove 15, they move the card holders 4 back and forth inside the vertical groove 5. The card holders 4 have horizontal grooves 21 on their surface, and a sliding plate 22 is provided inside the horizontal grooves 21. Both ends of the sliding plate 22 are connected to electric rotating wheels 23, and the surface of the electric rotating wheels 23 is in contact with the bottom side of the ring 7. The sliding plate 22 is correspondingly snapped into the ring groove 6. When the sliders 18 move inside the groove, they drive the card holders 4 to move synchronously, which can adjust the relative distance between the outer end of the card holders 4 and the outer circumference of the outer frame 1. The sliding plate 22 has a small battery inside, which provides power to the electric rotating wheels 23.

[0037] After the rotating block 17 and the bottom ring 9 define the middle column 8 inside the outer frame 1, and the position of the middle column 8 is completely defined, when the lifting device and the grid frame rod need to be locked together, the electric rotating wheel 23 at both ends of the slide plate 22 rotates. The friction between the electric rotating wheel 23 and the ring 7 causes the ring 7 to rotate inside the ring groove 6. When the ring 7 rotates, the spiral effect between the ring 7 and the inner side wall of the outer ring causes the ring 7 to move up and down inside the ring groove 6.

[0038] When the ring 7 moves down, the ring 7 uses the inner ring 13 to drive the cross plate 14 to move down on the surface of the middle column 8. At this time, the inner end of the slider 18 is always in contact with the outer side of the wedge block 16 under the elastic force of the elastic element 20. Multiple sliders 18 approach each other during the process of the inner ring 13 sliding down. At this time, the slider 18 drives the outer end of the card holder 4 to gradually approach the vertical groove 5. When the outer frame 1 enters the interior of the space frame member, it can avoid collision damage between the outer end of the card holder 4 and the inner wall of the through groove of the space frame member.

[0039] When the ring 7 moves upward, the ring 7 uses the inner ring 13 to drive the cross plate 14 to move upward on the surface of the middle column 8. During the upward movement of the inner ring 13, the multiple sliders 18 are separated from each other due to the limitation of the multiple wedge blocks 16. At this time, the sliders 18 drive the outer end of the bracket 4 to gradually move away from the vertical groove 5. The outer end of the bracket 4 gradually comes into contact with the inner wall of the through groove of the space frame member. By using the pressure contact between the bracket 4 and the inner wall of the through groove of the space frame member, it is convenient to complete the precise installation of the lifting device and the space frame member. When the spraying device is used to spray the surface of the space frame member, the surface of the space frame member can be fully sprayed in one go without the need for secondary touch-up painting. After the spraying is completed, the rotating block 17 is turned. When the rotating block 17 moves up at the top of the outer frame 1, the elastic force of the spring 11 uses the pressure plate 12 to make the bottom ring 9 move up inside the outer frame 1. When the bottom ring 9 drives the middle column 8 to move up, the middle column 8 drives multiple wedge blocks 16 to move up inside the cross-shaped through groove 15. The elastic force of the elastic element 20 makes the slider 18 slide inside the groove. Multiple sliders 18 are locked together and close to each other. At this time, the outer end of the bracket 4 separates from the inner wall of the through groove of the space frame member, which facilitates the quick separation of the space frame member from the lifting device.

[0040] Working principle of this invention:

[0041] Refer to the attached diagram in the instruction manual. Figures 1-4 When it is necessary to attach the lifting device to the corresponding slot inside the steel structure's space frame member, the outer frame 1 is attached to the corresponding slot inside the space frame member. At this time, the clamp 3 is pushed to slide on the surface of the square and round rod 2 until the clamp 3 is attached to the outer circumference of the space frame member. When the outer frame 1 slides inside the slot of the space frame member, due to the limiting cooperation between the clamp 3 and the square and round rod 2, the outer frame 1 can move smoothly inside the slot of the space frame member, avoiding collision damage between the outer frame 1 and the inner wall of the space frame member during the movement.

[0042] After the middle post 8 is snapped into the inner part of the outer frame 1 through the opening at the top of the outer frame 1, it is screwed into the top opening of the outer frame 1 by the rotating block 17. The rotating block 17 can limit the top of the middle post 8. The rotating block 17 cooperates with the bottom ring 9 to adjust the real-time position of the middle post 8 inside the outer frame 1.

[0043] After the rotating block 17 and the bottom ring 9 define the middle column 8 inside the outer frame 1, and the position of the middle column 8 is completely defined, when the lifting device and the grid frame rod need to be locked together, the electric rotating wheel 23 at both ends of the slide plate 22 rotates. The friction between the electric rotating wheel 23 and the ring 7 causes the ring 7 to rotate inside the ring groove 6. When the ring 7 rotates, the spiral effect between the ring 7 and the inner side wall of the outer ring causes the ring 7 to move up and down inside the ring groove 6.

[0044] When the ring 7 moves down, the ring 7 uses the inner ring 13 to drive the cross plate 14 to move down on the surface of the middle column 8. At this time, the inner end of the slider 18 is always in contact with the outer side of the wedge block 16 under the elastic force of the elastic element 20. Multiple sliders 18 approach each other during the process of the inner ring 13 sliding down. At this time, the slider 18 drives the outer end of the card holder 4 to gradually approach the vertical groove 5. When the outer frame 1 enters the interior of the space frame member, it can avoid collision damage between the outer end of the card holder 4 and the inner wall of the through groove of the space frame member.

[0045] When the ring 7 moves upward, the ring 7 uses the inner ring 13 to drive the cross plate 14 to move upward on the surface of the middle column 8. During the upward movement of the inner ring 13, the multiple sliders 18 are separated from each other due to the limitation of the multiple wedge blocks 16. At this time, the sliders 18 drive the outer end of the bracket 4 to gradually move away from the vertical groove 5. The outer end of the bracket 4 gradually comes into contact with the inner wall of the through groove of the space frame member. By using the pressure contact between the bracket 4 and the inner wall of the through groove of the space frame member, it is convenient to complete the precise installation of the lifting device and the space frame member. When the spraying device is used to spray the surface of the space frame member, the surface of the space frame member can be fully sprayed. After the spraying is completed, the rotating block 17 is turned. When the rotating block 17 moves up at the top of the outer frame 1, the elastic force of the spring 11 uses the pressure plate 12 to make the bottom ring 9 move up inside the outer frame 1. When the bottom ring 9 drives the middle column 8 to move up, the middle column 8 drives multiple wedge blocks 16 to move up inside the cross-shaped through groove 15. The elastic force of the elastic element 20 makes the slider 18 slide inside the groove. Multiple sliders 18 are locked together and close to each other. At this time, the outer end of the bracket 4 separates from the inner wall of the through groove of the space frame member, which facilitates the quick separation of the space frame member from the lifting device.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
