AI Technical Summary
During the high-altitude construction of the existing factory steel structure, operators need to repeatedly climb to high altitudes to untie the slings, which poses a risk of falling. The construction pace is also limited. During the hoisting process, the slings exert radial pressure on the steel pipes, causing plastic deformation at the joints, which affects the accuracy and lifespan.
The system employs a fixed plate, slings, and a release mechanism. The release mechanism is driven by two people pulling the traction rope synchronously, which automatically releases the slings. The dual traction rope linkage design prevents single-person misoperation. The spacing between the sling connection points is adjusted using positive and negative threaded rods, and the support rod assembly balances the sling force to prevent steel pipe deformation.
This eliminates the need for manual untying at heights, reducing operational risks, improving construction efficiency, and protecting the precision and lifespan of steel pipe connections.

Description
Technical Field
[0001] This invention belongs to the technical field of steel structure construction equipment, specifically relating to a high-altitude construction equipment for steel structures in factory buildings. Background Technology
[0002] Bolted ball steel space frames are widely used in modern factories, stadiums, and other large-span buildings. Their installation typically employs a high-altitude hoisting process: first, slings are secured to the steel pipe nodes of the bolted ball steel space frame, then the entire structure is lifted to the designed position using a crane; after the bolts are manually connected and secured, operators must climb back onto the newly installed space frame to manually untie the slings. This process has the following drawbacks:
[0003] Operators need to climb repeatedly at heights of tens of meters above the ground. When the slings are untied, their center of gravity shifts outward, making them extremely prone to falling. After each hoisting operation, they have to wait for manual untying of the slings, which severely restricts the construction pace. During the hoisting process, the slings exert continuous inward radial pressure on the steel pipes, which can easily cause plastic deformation at the joints, affecting the overall accuracy and service life of the space frame. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a high-altitude construction device for steel structures in factory buildings, which can reduce the risks during the construction process.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0006] A high-altitude construction device for steel structures in factory buildings includes a fixing plate, a sling, and a release mechanism; both ends of the sling are fixedly connected to limit pins; both ends of the fixing plate are connected to adjusting plates; both adjusting plates are provided with sling connection holes that cooperate with the sling and limit pin connection holes that cooperate with the limit pins.
[0007] Both adjusting plates are equipped with limiting components; the limiting components include limiting slide plates and limiting plates; the limiting slide plates are slidably connected to the adjusting plates, and a first spring is provided between the limiting slide plates and the adjusting plates; the limiting slide plates can block the connecting hole of the limiting pin; the limiting plates are fixedly connected to the adjusting plates, and the limiting slide plates are equipped with limiting protrusions; the limiting protrusions and the limiting plates clamp the limiting pin;
[0008] The unhooking mechanism includes a traction rope and a sliding plate; the sliding plate is slidably connected to the fixed plate, and a second spring is provided between the sliding plate and the fixed plate; there are two traction ropes, and each limiting slide plate is connected to one traction rope; the sliding plate is provided with a connecting component connected to the traction rope; when the two traction ropes are pulled synchronously, they drive the sliding plate and the limiting slide plate to move.
[0009] The end of the limiting slide plate is provided with a plug-in block, and the limiting plate is provided with a slot for connecting to the plug-in block.
[0010] A snap-fit plate is fixedly connected to the traction rope, and the snap-fit plate has a snap-fit groove.
[0011] The connecting assembly includes a connecting plate and a connecting post. The middle part of the connecting plate is hinged to the sliding plate. The two ends of the connecting plate are provided with hooks, and the fixed plate is provided with a pair of limiting posts that cooperate with the hooks. The two ends of the connecting plate are fixedly or rotatably connected to the connecting post. The traction rope passes through the connecting post, and the connecting post is provided with a corresponding through hole. The traction rope is provided with a limiting ring, and the outer diameter of the limiting ring is larger than the inner diameter of the through hole.
[0012] The limiting ring is sleeved outside the traction rope, and a fixing screw is threaded onto the limiting ring. The end of the fixing screw can pass through the limiting ring and abut against the traction rope.
[0013] Two sliders are slidably connected to the fixed plate, and a positive and negative threaded rod is rotatably connected to the fixed plate; both sliders are threadedly connected to the positive and negative threaded rods; by rotating the positive and negative threaded rods, the two sliders move in opposite directions or relative to each other; two adjusting plates are rotatably connected to the corresponding sliders respectively.

[0016] The support rod is threadedly connected to the support slider.
[0017] A rubber contact head is fixed to the outer end of the support rod.
[0018] Compared with the prior art, the beneficial effects of this invention are:
[0019] By having two people pull the traction rope synchronously to drive the unhooking mechanism, the limit plate retracts to release the limit pin, and the sling automatically resets and disengages, avoiding the risks of manual unhooking operations at height.
[0020] The unhooking mechanism features a dual-traction rope linkage design (hook + limit post), requiring two workers to operate simultaneously to trigger unlocking, thus preventing accidental operation by a single person.

[0022] The support rod assembly is adjustable in height and length. Its end rubber contact head presses against the steel pipe to form an external support force that balances the inward force applied by the sling, effectively preventing deformation and damage at the steel pipe connection.

Detailed Implementation
[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0037] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a high-altitude construction device for steel structure of factory buildings includes a fixing plate 1, a sling 2 and a release mechanism 3; both ends of the sling 2 are fixedly connected with limit pins 4.
[0038] Adjustable plates 5 are connected to both ends of the fixed plate 1; each of the two adjustable plates 5 is provided with a sling connection hole 50 that mates with the sling 2 and a limit pin connection hole 51 that mates with the limit pin 4, meaning that the sling 2 and the limit pin 4 can pass through the adjustable plates 5 through the corresponding sling connection hole 50 and limit pin connection hole 51. Specifically, the length of the limit pin 4 is greater than the width of the sling 2 and the sling connection hole 50. Figure 8 As shown in (a), in the unlifted state, the sling 2 passes through the adjusting plate 5, and the limiting pin 4 is located below the sling connection hole 50.
[0039] Both adjusting plates 5 are equipped with limiting components 6, which restrict the movement of the limiting pin 4. The limiting component 6 includes a limiting slide plate 60 and a limiting plate 61; the limiting slide plate 60 is slidably connected to the adjusting plate 5, and a first spring 62 is provided between the limiting slide plate 60 and the adjusting plate 5, with both ends of the first spring 62 abutting against the limiting slide plate 60 and the adjusting plate 5 respectively; the limiting slide plate 60 can block the limiting pin connection hole 51, and by pushing the limiting slide plate 60 to slide (the first spring 62 is compressed), the limiting slide plate 60 is exposed to the limiting pin connection hole 51, and the limiting pin 4 can pass through the limiting pin connection hole 51 to pass through the adjusting plate 5.
[0040] The limiting plate 61 is fixedly connected to the adjusting plate 5, and the limiting slide plate 60 is provided with a limiting protrusion 63; the limiting protrusion 63 and the limiting plate 61 clamp the limiting pin 4, which further serves to fix the limiting pin 4.
[0041] like Figure 8 As shown in (b), when it is necessary to hoist the bolted ball steel space frame 11, taking one end of the sling 2 as an example: first, pull the sling 2 to wrap around the steel pipe 10 of the bolted ball steel space frame 11; then push the limiting slide plate 60 to expose the limiting pin connection hole 51, and then extend the limiting pin 4 through the limiting pin connection hole 51 to the top of the adjusting plate 5 (while maintaining a certain distance so that the limiting slide plate 60 can be reset); finally, remove the external force, and the first spring 62 releases its elastic potential energy to push the limiting slide plate 60 to be reset. After the limiting slide plate 60 is reset, it will block the limiting pin connection hole 51 and be located below the limiting pin 4.
[0042] like Figure 9 and Figure 10 As shown, install the other end of the sling 2 in the manner described above. After both ends of the sling 2 are installed, use a crane to hook the middle of the sling 2 to hoist the sling 2 and the bolted ball steel grid 11 to the required installation position.
[0043] like Figure 2 , Figure 4 and Figure 5 As shown, the unhooking mechanism 3 includes a traction rope 30 and a sliding plate 31. The sliding plate 31 is slidably connected to the fixed plate 1, and a second spring 32 is provided between the sliding plate 31 and the fixed plate 1. The two ends of the second spring 32 abut against the sliding plate 31 and the fixed plate 1, respectively. When the sliding plate 31 moves, the second spring 32 is compressed to generate elastic potential energy. There are two traction ropes 30, and each limiting slide plate 60 is connected to one traction rope 30. The sliding plate 31 is provided with a connecting assembly 33 for connecting the traction ropes 30. Only when both traction ropes 30 are pulled synchronously will the sliding plate 31 and the limiting slide plate 60 move; otherwise, if only one traction rope 30 is pulled, the sliding plate 31 and the limiting slide plate 60 cannot move.
[0044] After hoisting to the installation position and completing the installation, two workers simultaneously pull the two traction ropes 30, moving the sliding plate 31 and the limiting slide plate 60. At this time, the limiting slide plate 60 exposes the limiting pin connection hole 51; then the crane pulls up the sling 2, moving it until it returns to the un-hoisted state (the sling 2 passes through the adjusting plate 5, and the limiting pin 4 is located below the sling connection hole 50). Finally, the workers release the traction ropes 30, and the crane moves the device to the next location requiring hoisting, where it can be hoisted again.
[0045] Using the above method, the connection and separation (untying) of the sling 2 and the bolted ball steel space frame 11 can be quickly achieved; during the separation process, it is not necessary for operators to climb to the installation location of the sling 2 to untie it. Furthermore, the untying of the sling 2 requires two workers to operate simultaneously, thus avoiding accidental operation.
[0046] Furthermore, such as Figure 6 As shown, to improve connection stability, the end of the limiting slide plate 60 is provided with a plug-in block 34, and the limiting plate 61 is provided with a slot 35 that connects to the plug-in block 34. When the limiting slide plate 60 blocks the limiting pin connection hole 51, the plug-in block 34 and the slot 35 are in an inserted state. When the limiting slide plate 60 exposes the limiting pin connection hole 51, the plug-in block 34 and the slot 35 are in a separated state.
[0047] Furthermore, during hoisting, the traction rope 30 can be attached to the end (bolt position) of the steel pipe 10. For example... Figure 1 and Figure 9As shown, to facilitate the operator's grip, a snap-fit plate 36 is fixedly connected to the traction rope 30, and the snap-fit plate 36 has a snap-fit groove; during hoisting, the snap-fit plate 36 is simply snapped onto the end of the steel pipe 10. After installation, the traction rope 30 can be pulled by pulling out the snap-fit plate 36 to detach it from the steel pipe 10.
[0048] Furthermore, such as Figure 4 and Figure 5 As shown, the connecting assembly 33 includes a connecting plate 330 and a connecting post 331. The middle part of the connecting plate 330 is hinged to the sliding plate 31. The two ends of the connecting plate 330 are provided with hooks 335, and the fixed plate 1 is provided with a pair of limiting posts 332 that cooperate with the hooks 335. When only one traction rope 30 is pulled, the connecting plate 330 rotates and moves a small distance. The hooks 335 on it will hook the corresponding limiting posts 332, thereby restricting the connecting plate 330 from continuing to rotate and move.
[0049] Both ends of the connecting plate 330 are fixedly or rotatably connected to connecting posts 331. The traction rope 30 passes through the connecting posts 331, and the connecting posts 331 have corresponding through holes; the traction rope 30 is provided with a limiting ring 333, the outer diameter of the limiting ring 333 is larger than the inner diameter of the through hole, and the limiting ring 333 cannot pass through the through hole.
[0050] When only one of the traction ropes 30 is pulled, the limiting ring 333 cannot pass through the through hole, which will apply a pulling force to one side of the connecting plate 330, causing the connecting plate 330 to tend to rotate; the hook 335 on it will hook the corresponding limiting post 332, and cannot continue to move. Therefore, pulling only one traction rope 30 cannot move the connecting plate 330, and thus cannot move the limiting slide plate 60. However, when both traction ropes 30 are pulled simultaneously, the two sides of the connecting plate 330 are subjected to a pulling force (the hook 335 does not contact the limiting post 332), which will cause the sliding plate 31 and the limiting slide plate 60 to move.
[0051] Furthermore, such as Figure 3 and Figure 5 As shown, two sliders 7 are slidably connected to the fixed plate 1, and a threaded rod 8 is rotatably connected to the fixed plate 1; both sliders 7 are threadedly connected to the threaded rod 8; two adjusting plates 5 are rotatably connected to their corresponding sliders 7. By rotating the threaded rod 8, the two sliders 7 move in opposite directions or relative to each other, thereby changing the distance between the two adjusting plates 5, thus changing the connection position between the sling 2 and the bolted ball steel space frame 11, adapting to the hoisting of bolted ball steel space frames 11 of different specifications.
[0052] When the position of the adjusting plate 5 changes, the distance between the connecting post 331 and the limiting slide plate 60 also changes. Therefore, the position of the limiting ring 333 needs to be adjusted accordingly. To facilitate the adjustment of the position of the limiting ring 333, the following structural design is adopted:
[0053] like Figure 2 and Figure 4 As shown, the limiting ring 333 is sleeved on the outside of the traction rope 30, and the position of the limiting ring 333 can be changed as needed. Then tighten the fixing screw 334, the end of the fixing screw 334 can pass through the limiting ring 333 and abut against the traction rope 30.
[0054] Furthermore, such as Figure 3 As shown, for ease of gripping, a drive sleeve 80 is fixedly connected to the middle of the positive and negative threaded rod 8.
[0055] Furthermore, such as Figure 1 , Figure 2 and Figure 9 As shown, during the hoisting process, inward pressure is applied to the steel pipes 10 connected to both ends of the sling 2, which may cause irreversible damage to the connection of the steel pipes 10. Therefore, a support rod assembly 9 is provided on the fixing plate 1; the support rod assembly 9 supports the steel pipes 10 and provides support.
[0056] The support rod assembly 9 includes a support plate 90 and a support slider 91, with the support plate 90 fixedly connected to the fixed plate 1. The support slider 91 is slidably connected to the support plate 90, and the support slider 91 and the support plate 90 are fixed together by adjusting screws 92. Support rods 93 are connected to both ends of the support slider 91, and the steel pipe 10 is supported by the outer ends of the support rods 93.
[0057] By changing the position of the support slider 91, the axis of the support rod 93 is aligned with the axis of the steel pipe 10 in the same horizontal plane. Specifically, the support plate 90 has a through groove, through which the adjusting screw 92 passes and is threadedly connected to the support slider 91. By tightening the adjusting screw 92, the head of the adjusting screw 92 contacts the support plate 90, thus fixing the position between the two.
[0058] Furthermore, the support rod 93 is threadedly connected to the support slider 91; the support rod 93 can be rotated as needed to change its extension length, so as to ensure that the outer end of the support rod 93 can contact the steel pipe 10.
[0059] Furthermore, such as Figure 2 As shown, a rubber contact head 94 is fixed at the outer end of the support rod 93 to avoid damage to the outer surface of the steel pipe 10.
[0060] The above description only illustrates preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
