Description
Technical Field
[0001] This utility model relates to the field of steel structure processing shed technology, specifically a rapid locking structure solution for steel structure processing sheds. Background Technology
[0002] Steel structure processing sheds play a vital role on construction sites, primarily used for storing and processing steel. These sheds provide effective protection for various steel materials and construction workers, shielding them from adverse weather conditions such as sun, rain, and wind. On construction sites, the project schedule is constantly changing, requiring steel structure processing sheds to be rapidly erected and dismantled to adapt to different construction stages. Therefore, a rapid locking structure for steel structure processing sheds is proposed.
[0003] Chinese utility model patent CN219327370U discloses a steel bar processing shed with a stable structure. This shed includes several opposing main support rods, with a first crossbar between adjacent main support rods. The first crossbar has a limiting groove that engages with the main support rod. This structure limits the main support rods through the limiting groove, allowing the main body of the shed to be assembled together. Furthermore, the triangular cross-section formed by the diagonal rods allows workers to install a tarpaulin on top of the base plate, increasing its functional versatility.
[0004] Such a steel bar processing shed has a small usable area, making it inconvenient for multiple people to work on it. In addition, the processing shed itself does not have a rainproof effect. If waterproofing is required, an additional tarpaulin needs to be laid, resulting in poor performance. The assembly of the clamps is also time-consuming and cannot be done quickly. Summary of the Invention
[0005] In view of the shortcomings of existing steel bar processing sheds in terms of practicality and rain protection, the purpose of this utility model is to provide a quick-locking structure for steel structure processing sheds, which can effectively solve the problems in the prior art.
[0006] To achieve the above objectives, the present invention provides a quick-locking structure for a steel structure processing shed, comprising a lifting frame, side frames on both sides of the lifting frame, a support fixedly connected to the outer side of the side frame, a screw on the upper end of the support, an adjusting rod on the outer side of the screw, a wheel fixedly connected to the lower end of the screw, and a lifting canopy on the upper end of the lifting frame.
[0007] Preferably, the lifting frame includes upper and lower horizontal bars, side vertical bars, a first sliding groove, a central vertical bar, a second sliding groove, a lifting turntable, a rotating handle, a fixed pulley, a fixed seat, and a lifting rope. The side vertical bars and the central vertical bar are fixedly connected to the center. The front end of the side vertical bar has a first sliding groove, and the front end of the central vertical bar has a second sliding groove. The front end of the central vertical bar is provided with a lifting turntable, and the front end of the lifting turntable is fixedly connected with a rotating handle. The front end of the central vertical bar is provided with a fixed pulley and a fixed seat, and the outside of the fixed seat is fixedly connected with a lifting rope.
[0008] Preferably, the lifting canopy includes a base frame, a sliding tube, a movable pulley, a secondary frame, a bearing seat, a locking rod, a connecting seat, a hook, a lower canopy, and an upper canopy. The base frame is fixedly connected to the front and rear ends of the sliding tube. A movable pulley is provided at the front end of the sliding tube. The secondary frame is fixedly connected to the upper end of the base frame. The bearing seat is fixedly connected to the lower end of the secondary frame. A locking rod is fixedly connected to the outside of the bearing seat. A connecting seat is rotatably connected to the outside of the bearing seat. A hook is fixedly connected to the outside of the connecting seat. The lower canopy is fixedly connected to the lower end of the connecting seat. The upper canopy is fixedly connected to the upper end of the secondary frame.
[0009] Preferably, the screw and the support are threadedly connected, and the adjusting rod and the screw are slidably connected.
[0010] The above technical solution includes a support, a screw, an adjusting rod, and a rotating wheel. After the processing shed is deployed, when the position of the processing shed needs to be moved or adjusted, the adjusting rod is rotated to drive the screw to rotate. The screw is threadedly connected to the support. The screw moves downward along the support until the rotating wheel contacts the ground, thus lifting the top of the processing shed off the ground and allowing the processing shed to be moved to adjust its position.
[0011] Preferably, the side frame and the side frame are locked together by bolts, and the first slide groove and the second slide groove are slidably connected to the slide tube.
[0012] With the above technical solution, a side frame is set up. During assembly, the lifting canopy is first placed on the ground, and two lifting frames are placed symmetrically at the front and rear ends of the lifting canopy. The sliding tube is inserted into the sliding groove one and sliding groove two. The side frame bolts are then tightened and installed on both sides of the lifting canopy, and the lifting operation of the lifting canopy can be carried out. The operation is convenient.
[0013] Preferably, the movable pulley and the slide tube are locked together by bolts, and the central vertical frame is located at the center of the two side vertical frames.
[0014] The above technical solution involves using bolts to lock the movable pulley onto the sliding tube during installation, providing a limit for the lifting frame and the lifting ceiling.
[0015] Preferably, both the movable pulley and the fixed pulley are adapted to the lifting rope, and the two ends of the lifting rope are respectively fixedly connected to the fixed seat and the lifting turntable.
[0016] The above technical solution involves passing the lifting rope through the lower end of the movable pulley and the upper end of the fixed pulley. When the lifting canopy needs to be raised, two workers hold the handles of the two lifting turntables and rotate them in the same direction. The lifting rope is wound up by the lifting turntables, which drives the movable pulley and the lifting canopy to move upward along the second slide rail until the appropriate height is reached. The handles are then locked to the central vertical frame with bolts to lock the lifting canopy. This design allows the lifting canopy to be prefabricated, eliminating the need for workers to erect the canopy on-site, reducing the risks of working at heights, simplifying the deployment process, and increasing the assembly speed. The movable pulley is relatively labor-saving, saving manpower. The lifting canopy and lifting frame are detachable and reusable, making it very practical.
[0017] Preferably, the lower end of the hook has a hook groove that matches the hook rod, and the shaft seat and the connecting seat are rotatably connected.
[0018] The above technical solution incorporates hooks and rods. When assembling the lifting canopy and the lifting frame, the lower canopy is folded upwards along the center of the shaft seat and connecting seat until the hooks and rods engage. When the slide groove engages with the slide tube, the front-to-back width of the two lower canopies is less than the distance between the two lifting frames, facilitating lifting. After the lifting canopy is lifted, a long rod is used to push the hooks upwards, causing them to separate from the rods. The lower canopy then folds downwards to contact the secondary frame. At this point, the lower canopy is parallel to the upper canopy, and the lower canopy extends out of the lifting frame, providing better rain protection.
[0019] Preferably, both the lower and upper top layers are made of stainless steel corrugated sheets, and after the hooks and rods are separated, the lower and upper top layers are parallel and have overlapping portions.
[0020] With the above technical solution, after deployment, the lower roof and the upper roof are parallel and overlap, and with the inclined roof structure, rainwater will not accumulate, and the rainproof effect is good.
[0021] Compared with the prior art, the quick-locking structure of the steel structure processing shed provided by this utility model has the following beneficial effects:
[0022] 1. The quick-locking structure of this steel structure processing shed is equipped with a support, screw, adjusting rod and rotating wheel. After the processing shed is deployed, when it is necessary to move and adjust the position of the processing shed, rotate the adjusting rod to drive the screw to rotate. The screw is threadedly connected to the support. The screw moves downward along the support until the rotating wheel contacts the ground, lifting the top of the processing shed off the ground, and then the processing shed can be pushed to adjust its position.
[0023] 2. This steel structure processing shed features a quick-locking structure with side frames. During assembly, the lifting shed is first placed on the ground, and two lifting frames are symmetrically placed at the front and rear ends of the lifting shed. The sliding pipes are inserted into slide groove one and slide groove two. The side frame bolts are then tightened and installed on both sides of the lifting shed. The lifting rope passes through the lower end of the movable pulley and the upper end of the fixed pulley. When the lifting shed needs to be raised, two workers hold the handles of the two lifting turntables and rotate the handles in the same direction. The lifting ropes are wound up by the lifting turntables, driving the movable pulley and the lifting shed to move upward along slide groove two until the appropriate height is reached. The handles are then locked to the central vertical frame with bolts, completing the locking of the lifting shed. This design allows the lifting shed to be prefabricated, eliminating the need for workers to erect the shed on-site, reducing the risks of working at heights, simplifying the deployment process, and increasing assembly speed. The movable pulleys are relatively labor-saving, and the lifting shed and lifting frames are detachable and reusable, making it very practical.
[0024] 3. The quick-locking structure of this steel structure processing shed is equipped with hooks and rods. When assembling the lifting shed and the lifting frame, the lower shed is folded upwards along the center of the shaft seat and the connecting seat until the hooks and rods are engaged. When the slide chute is engaged with the slide tube, the front-to-back width of the two lower sheds is less than the distance between the two lifting frames, which facilitates lifting. After the lifting shed is lifted, the hooks are pushed upwards with a long rod to separate them from the rods. The lower shed is then folded downwards to contact the secondary frame. At this time, the lower shed is parallel to the upper shed and extends out of the lifting frame. After deployment, the lower shed is parallel to the upper shed and has an overlapping part. Combined with the inclined roof structure, rainwater will not accumulate, resulting in good rain protection. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example 1:
[0035] like Figure 1-2 As shown, this is an example of the configuration scheme of the quick-locking structure of the steel structure processing shed in this example.
[0036] Based on the diagram, the quick-locking structure of the steel structure processing shed given in this example mainly includes a lifting frame 1, side frames 2 on both sides of the lifting frame 1, a support 3 fixedly connected to the outside of the side frames 2, a screw 4 on the upper end of the support 3, an adjusting rod 5 on the outside of the screw 4, a wheel 6 fixedly connected to the lower end of the screw 4, and a lifting canopy 7 on the upper end of the lifting frame 1.
[0037] See further Figure 3 and Figure 4 The lifting frame 1 in the quick-locking structure of this steel structure processing shed specifically includes upper and lower horizontal bars 101, side vertical frames 102, slide groove one 103, central vertical frame 104, slide groove two 105, lifting turntable 106, handle 107, fixed pulley 108, fixed seat 109 and lifting rope 110.

[0039] See further Figure 5 and Figure 6 The lifting canopy 7 in the quick-locking structure of this steel structure processing shed specifically includes a base frame 701, a sliding tube 702, a movable pulley 703, a secondary frame 704, a bearing seat 705, a clamping rod 706, a connecting seat 707, a hook 708, a lower canopy 709, and an upper canopy 710.
[0040] The base frame 701 is fixedly connected to the front and rear ends of the slide tube 702. The front end of the slide tube 702 is provided with a movable pulley 703. The upper end of the base frame 701 is fixedly connected to the secondary frame 704. The lower end of the secondary frame 704 is fixedly connected to the bearing seat 705. The outer side of the bearing seat 705 is fixedly connected to the locking rod 706. The outer side of the bearing seat 705 is rotatably connected to the connecting seat 707. The outer side of the connecting seat 707 is fixedly connected to the locking hook 708. The lower end of the connecting seat 707 is fixedly connected to the lower top 709. The upper end of the secondary frame 704 is fixedly connected to the upper top 710.
[0041] Accordingly, the following details the structural features of the quick-locking structure of the steel structure processing shed presented in this example.
[0042] Combination Figure 1 and Figure 2 As shown, in some embodiments of this example, the screw 4 and the support 3 in the quick-locking structure of this steel structure processing shed are preferably threadedly connected, and the adjusting rod 5 and the screw 4 are slidably connected. By setting the support 3, screw 4, adjusting rod 5 and rotating wheel 6, after the processing shed is deployed, when it is necessary to move and adjust the position of the processing shed, rotating the adjusting rod 5 drives the screw 4 to rotate. The screw 4 and the support 3 are threadedly connected, and the screw 4 moves downward along the support 3 until the rotating wheel 6 contacts the ground, lifting the top of the processing shed off the ground, thus pushing the processing shed to adjust its position.
[0043] Combination Figure 3 and Figure 4As shown, in some embodiments of this example, the side frame 102 and side frame 2 of the quick-locking structure of this steel structure processing shed are connected by bolts, and the sliding groove 103 and sliding groove 2 105 are slidably connected to the sliding tube 702. With the side frame 2 in place, during assembly, the lifting shed 7 is first placed on the ground, and the two lifting frames 1 are symmetrically placed at the front and rear ends of the lifting shed 7. The sliding tube 702 is inserted into the sliding groove 103 and sliding groove 2 105, and the side frame 2 is bolted and installed on both sides of the lifting shed 7, allowing for convenient lifting operations.
[0044] Combination Figure 5 and Figure 6 As shown, in some embodiments of this example, the movable pulley 703 of the quick-locking structure of this steel structure processing shed is connected to the slide tube 702 by bolts, and the central vertical frame 104 is set at the center of the two side vertical frames 102. Thus, during installation, the movable pulley 703 is bolted onto the slide tube 702, providing a limit for the lifting frame 1 and the lifting canopy 7.
[0045] Example 2:
[0046] This example presents a specific optimization scheme for the rapid locking structure of the steel structure processing shed given in Example 1.
[0047] like Figure 2-7 As shown, in this example, the movable pulley 703 and the fixed pulley 108 are both adapted to the lifting rope 110. The two ends of the lifting rope 110 are fixedly connected to the fixed base 109 and the lifting turntable 106, respectively. The lifting rope 110 passes through the lower end of the movable pulley 703 and the upper end of the fixed pulley 108. When the lifting canopy 7 needs to be raised, two workers hold the handles 107 of the two lifting turntables 106 and rotate the handles 107 in the same direction. The lifting rope 110 is wound up by the lifting turntable 106, which drives the movable pulley 703 and the lifting canopy 7 to move upward along the second slide groove 105 until the appropriate height is reached. The handles 107 are then locked to the central vertical frame 104 with bolts to complete the locking of the lifting canopy 7. With this design, the lifting canopy 7 can be prefabricated, eliminating the need for on-site canopy erection by staff, reducing the risk of working at heights, simplifying the deployment process, and increasing assembly speed. The installation of the movable pulley 703 is labor-saving and saves manpower. The lifting canopy 7 and the lifting frame 1 can be disassembled and reused, making it very practical.
[0048] Furthermore, in this example, a hook groove is provided at the lower end of the hook 708 to match the locking rod 706, and the shaft seat 705 and the connecting seat 707 are rotatably connected. With the hook 708 and locking rod 706 configured in this way, when assembling the lifting canopy 7 and the lifting frame 1, the lower top 709 is folded upward along the center of the shaft seat 705 and the connecting seat 707 until the hook 708 and the locking rod 706 are engaged. When the slide groove 103 and the slide tube 702 are engaged, the front and rear width of the two lower tops 709 is less than the distance between the two lifting frames 1, which facilitates lifting. After the lifting canopy 7 is lifted, the hook 708 is pushed upward with a long rod to separate the hook 708 from the locking rod 706. The lower top 709 is folded downward to contact the secondary frame 704. At this time, the lower top 709 is parallel to the upper top 710, and the lower top 709 extends out of the lifting frame 1, providing a better rainproof effect.
[0049] Furthermore, in this example, stainless steel corrugated sheets are used to construct both the lower roof 709 and the upper roof 710. After the hooks 708 and the rods 706 are separated, the lower roof 709 and the upper roof 710 are parallel and overlap. After this deployment, the lower roof 709 and the upper roof 710 are parallel and overlap, and with the sloping roof structure, rainwater will not accumulate, resulting in good rainproof performance.
[0050] To further illustrate the composition scheme and corresponding technical characteristics of the quick-locking structure of this steel structure processing shed, the following is combined with... Figures 1 to 7 Let me explain in detail the application process of the quick-locking structure of this steel structure processing shed.
[0051] During assembly, the quick-locking structure of this steel structure processing shed is assembled by folding the lower top 709 upwards along the center of the shaft seat 705 and the connecting seat 707 until the hook 708 and the locking rod 706 are engaged. The two lifting frames 1 are placed symmetrically at the front and rear ends of the lifting shed 7, so that the sliding tube 702 is inserted into the sliding groove 103 and the sliding groove 2 105. The side frame 2 is bolted and installed on both sides of the lifting shed 7. The lifting rope 110 passes through the lower end of the moving pulley 703 and through the upper end of the fixed pulley 108.
[0052] When it is necessary to raise the lifting ceiling 7, two workers hold the handles 107 of the two lifting turntables 106 and rotate the handles 107 in the same direction. The lifting rope 110 is wound by the lifting turntable 106, which drives the pulley 703 and the lifting ceiling 7 to move upward along the slide groove 105 until the appropriate height is reached. Then, the handles 107 are locked to the central vertical frame 104 with bolts to complete the locking of the lifting ceiling 7.
[0053] After the lifting canopy 7 is raised, the hook 708 is pushed upward with a long rod to separate the hook 708 from the rod 706. The lower canopy 709 flips down and contacts the secondary frame 704. At this time, the lower canopy 709 is parallel to the upper canopy 710. The lower canopy 709 extends out of the lifting frame 1. After deployment, the lower canopy 709 is parallel to the upper canopy 710 and has an overlapping part. With the inclined roof structure, rainwater will not accumulate and the rainproof effect is good. With this design, the lifting canopy 7 can be prefabricated, eliminating the need for workers to erect the canopy on site, reducing the risk of high-altitude operations, simplifying the deployment process, and increasing the assembly speed.
[0054] The movable pulley 703 is designed to be labor-saving and save manpower. The lifting canopy 7 and the lifting frame 1 are detachable and reusable, which is very practical. After the processing canopy is deployed, when it is necessary to move and adjust the position of the processing canopy, the adjusting rod 5 is rotated to drive the screw 4 to rotate. The screw 4 is threadedly connected to the support 3. The screw 4 moves downward along the support 3 until the rotating wheel 6 contacts the ground, thus lifting the top of the processing canopy off the ground, and the processing canopy can be pushed to adjust its position.
[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
