Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel bar processing support technology, and in particular to a steel bar processing support that is easy to transport and stack. Background Technology
[0002] In the construction industry, rebar processing is a crucial step in concrete structure construction. Rebar processing supports, as key equipment for supporting and fixing rebar, directly impact construction efficiency and cost. Traditional rebar processing supports mostly employ fixed steel structures, rigidly connecting multiple support components through welding or bolts to ensure stability during processing. However, as the construction industry moves towards prefabricated and modular construction, construction sites place higher demands on equipment mobility and space utilization. Especially when multiple projects are under continuous construction or relocated, the bulky size and fixed form of traditional supports lead to transportation difficulties and high costs. There is an urgent need to develop new types of supports with flexible folding and compact storage capabilities to meet the demands of efficient turnover in modern construction.
[0003] Existing steel bar processing supports mainly adopt fully welded or bolted structures. Fully welded supports directly weld multiple steel pipes or sections into a stable frame, using rigid connections to ensure the stable support of the steel bars during processing. Although bolted supports can disassemble components by removing bolts, each component still maintains a large size, and the assembly and disassembly process requires a lot of manpower and time.
[0004] However, existing steel bar processing supports are generally bulky and difficult to fold and store, resulting in high transportation costs and low space utilization. After construction, traditional fixed supports cannot be disassembled or folded and must be transported to the next site in their complete form. This not only requires renting large transport vehicles, but also limits the number of vehicles that can be transported at one time, significantly increasing logistics costs. During transportation, there is a risk of bumps and collisions with transport vehicles or surrounding facilities. Therefore, a steel bar processing support that is easy to transport and stack is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a steel bar processing support that is easy to transport and stack, aiming to improve the problems of existing steel bar processing supports being bulky, difficult to fold and store, resulting in high transportation costs and low space utilization.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A steel bar processing support that is easy to transport and stack includes a support frame, a universal wheel at the bottom of the support frame, a support shaft fixedly connected inside the support frame, a connecting frame rotatably connected to the outer wall of the support shaft, the connecting frame rotatably connected inside the support frame, a support component on the side wall of the connecting frame, and a limit component inside the connecting frame.
[0008] The support assembly includes a bracket, the side wall of which is fixedly connected to the side wall of the connecting frame. The support frame has a groove inside and a positioning pin inside. The positioning pin passes through the groove and the connecting frame. A bolt is threadedly connected to one side of the support frame and is slidably connected inside the connecting frame.
[0009] As a further description of the above technical solution:
[0010] The limiting assembly includes a connecting shaft and a limiting rod. The outer wall of the connecting shaft is fixedly connected to the inside of the connecting frame, and the limiting rod is rotatably connected to the outer wall of the connecting shaft.
[0011] As a further description of the above technical solution:
[0012] The connecting frame has a sliding groove inside, and the limiting rod is slidably connected inside the sliding groove.
[0013] As a further description of the above technical solution:
[0014] A fixing plate is fixedly connected to the side wall of the connecting frame, and a fixing block is fixedly connected to the top of the fixing plate.
[0015] As a further description of the above technical solution:
[0016] A support column is fixedly connected inside the fixed block, and a clamping block is rotatably connected to the outer wall of the support column.
[0017] As a further description of the above technical solution:
[0018] The outer wall of the support column is rotatably connected to a second clamping block. One side of the first clamping block has an internal groove, and one side of the second clamping block is slidably connected inside the internal groove.
[0019] As a further description of the above technical solution:
[0020] A connecting plate is fixedly connected to the outer wall of the first clamping block, and a connecting plate is fixedly connected to the outer wall of the second clamping block.
[0021] As a further description of the above technical solution:
[0022] Both the bottom of the connecting plate 1 and the connecting plate 2 are provided with springs, and the two ends of the two springs are respectively fixedly connected to the inside of the connecting plate 1, the connecting plate 2 and the fixing plate.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by pulling out the positioning pin, the connecting frame rotates around the support shaft and retracts to be close to the support frame, and then the positioning pin is inserted to fix it. When unfolded, the bolt is screwed into the connecting frame to fix the extended state. These structures work together to achieve the effect of quick folding and unfolding of the bracket, which solves the problem that steel bar processing brackets are generally bulky, difficult to fold and retract, resulting in high transportation costs and low space utilization, thereby improving the flexibility of steel bar processing brackets.
[0025] 2. In this utility model, the position of the limiting rod is adjusted by rotating it along the slide groove, which causes the clamping blocks one and two to rotate under force. This causes the connecting plate to compress the spring and then rebound to lock the limiting rod. During this process, the limiting rod blocks the steel bar to prevent it from rolling and slipping. The cooperation between the spring and the clamping blocks achieves a stable fixation of the limiting rod. These structures work together to achieve an effective limiting effect on the stacked steel bars, solving the problem that traditional supports lack reliable limiting devices and that steel bars are prone to rolling and slipping, resulting in poor stability during processing. This improves the stability of the steel bar processing support. Attached Figure Description

Detailed Implementation
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] Reference Figures 1-3 The present invention provides an embodiment of a steel bar processing support that is easy to transport and stack, comprising a support frame 1, a caster wheel 2 at the bottom of the support frame 1, the caster wheel 2 enabling the support frame 1 to move flexibly, a support shaft 3 fixedly connected inside the support frame 1, and a connecting frame 4 rotatably connected to the outer wall of the support shaft 3, providing the function of rotation and angle adjustment, allowing users to adjust the shape and angle of the support as needed, the connecting frame 4 rotatably connected inside the support frame 1, a support component provided on the side wall of the connecting frame 4, and a limit component provided inside the connecting frame 4;
[0035] The support assembly includes a bracket 5, the side wall of which is fixedly connected to the side wall of the connecting frame 4. The support frame 1 has a groove 6 inside and a positioning pin 7 inside. The positioning pin 7 passes through the groove 6 and the connecting frame 4. A bolt 8 is threadedly connected to one side of the support frame 1. The bolt 8 is slidably connected inside the connecting frame 4. The bolt 8 will penetrate into the internal structure of the connecting frame 4, thereby fixing the connecting frame 4 in the extended state. This design ensures the stability of the bracket.
[0036] Reference Figure 2 , Figure 4 and Figure 5The limiting assembly includes a connecting shaft 9 and a limiting rod 10. The outer wall of the connecting shaft 9 is fixedly connected to the inside of the connecting frame 4, and the limiting rod 10 is rotatably connected to the outer wall of the connecting shaft 9. A sliding groove 11 is provided inside the connecting frame 4, and the limiting rod 10 is slidably connected inside the sliding groove 11. The limiting rod 10 can be rotated to slide along the sliding groove 11 and adjust its position to effectively block and limit the reinforcing bars. A fixing plate 12 is fixedly connected to the side wall of the connecting frame 4, and a fixing block 13 is fixedly connected to the top of the fixing plate 12. A support column 14 is fixedly connected inside the fixing block 13. A clamping block 15 is rotatably connected to the outer wall of the support column 14, and a clamping block 2 16 is rotatably connected to the outer wall of the support column 14. A slot 17 is provided inside one side of the clamping block 15, and one side of the clamping block 2 16 is slidably connected inside the slot 17 to ensure that the clamping block 2 16 is slidably connected to the slot 17. 6 can slide smoothly under the guidance of clamping block 15. Clamping block 15 is fixedly connected to connecting plate 18, and clamping block 2 is fixedly connected to connecting plate 29. Both connecting plate 18 and connecting plate 29 are provided with springs 20 at their bottoms. The two ends of the two springs 20 are fixedly connected to the inside of connecting plate 18, connecting plate 29 and fixing plate 12 respectively. The two sets of clamping blocks play a supporting role, which can help the limiting rod 10 to be evenly stressed. When rotating, they drive the connecting plate 18 and connecting plate 29 on the outer wall to move synchronously. After being stressed, connecting plate 18 and connecting plate 29 will compress the springs 20 at the bottom, thereby providing elastic support for the limiting rod 10. This ensures that the limiting rod 10 can be automatically locked and prevented from loosening during the stacking of steel bars, ensuring that the steel bars are stable and do not shift within the bracket 5.
[0037] Working principle: During the process of using this steel bar to process the bracket, the connecting frame 4 is rotated and sleeved on the outer wall of the support shaft 3, so that the connecting frame 4 can rotate around the support shaft 3 within the support frame 1. When the bracket needs to be transported, the connecting frame 4 can be operated to fold and retract towards the support frame 1. When folding, pull out the groove 6 passing through the support frame 1 and the positioning pin 7 inside the connecting frame 4 to release the angle lock between the connecting frame 4 and the support frame 1. After rotating the connecting frame 4 to the folding position close to the support frame 1, reinsert the positioning pin 7 so that it passes through the groove 6 and the corresponding hole of the connecting frame 4 to fix the folded state. When unfolding, tighten the bolt 8 threaded on one side of the support frame 1 to tighten it along the thread and insert it into the inside of the connecting frame 4 to fix it in the extended state, thereby achieving the effect of easy folding and transportation of the bracket.
[0038] The bracket 5 is used to place the reinforcing bars. To prevent the reinforcing bars from rolling and falling, the limiting rod 10 is rotated during use, allowing it to slide along the groove 11 to adjust its position and block and limit the reinforcing bars, preventing them from stacking and falling. At the same time, during the rotation, the limiting rod 10 will contact the clamping blocks 15 and 16 on the side wall of the connecting frame 4, causing it to rotate to both sides under force. The clamping blocks 15 and 16 drive the connecting plates 18 and 19 on the outer wall to move. The connecting plates 18 and 19 compress the spring 20 at the bottom under force. When the limiting rod 10 slides between the clamping blocks 15 and 16, the spring 20 releases the force and rebounds, thereby driving the clamping blocks 15 and 16 to reset, fixing the limiting rod 10. This achieves the effect of effectively limiting the stacked reinforcing bars.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
