Description

Technical Field

[0001] This utility model relates to the field of electrical engineering construction technology, and specifically to a portable round steel bending tool. Background Technology

[0002] In electrical engineering construction, lightning protection grounding work mainly focuses on two stages: foundation construction and main structure construction. During the foundation raft slab reinforcement construction, the reinforcement teams carry out large-scale construction, with a rapid pace of progress. After the reinforcement work is completed, the pouring operation begins, and the electromechanical installation work can only be carried out in an interleaved manner, resulting in a relatively limited construction time. Under these circumstances, lightning protection grounding work is characterized by numerous work points, a wide work area, heavy construction tasks, and limited construction time.

[0003] Galvanized round steel, as the main material used for lightning protection grounding, usually needs to be processed into right-angle bends and ohmic bends. Existing bending tools can generally only produce right-angle bends or ohmic bends individually, and most of them are one-piece fixed structures, which are inconvenient to move and carry. In addition, they can generally only be operated on a flat surface and cannot be directly fixed on the steel mesh. Utility Model Content

[0004] To address the technical problems in the prior art, this utility model provides a portable round steel bending tool, including a support frame, a right-angle bending workbench, and an ohmic bending workbench. Both the right-angle bending workbench and the ohmic bending workbench are detachably connected to the support frame. The support frame includes a fixed plate and a support plate. The fixed plate is movably connected to the support plate via an adjusting assembly. Both the right-angle bending workbench and the ohmic bending workbench are detachably connected to the fixed plate via bolts. The support plate has multiple T-shaped grooves symmetrically arranged at both ends along the vertical direction. T-shaped sliders are slidably arranged within the T-shaped grooves. A clamping assembly is fixedly installed at the bottom end of each T-shaped slider. The clamping assembly is detachably connected to the steel bar. The clamping assembly slides out or retracts to the bottom of the support plate under the influence of the T-shaped slider.

[0005] Furthermore, the fixing plate is provided with a plurality of limiting holes of different shapes at intervals, and the bottom of the right-angle bending worktable and the ohmic bending worktable are provided with a plurality of limiting bosses. The right-angle bending worktable and the ohmic bending worktable are connected to the limiting holes through the limiting bosses.

[0006] Furthermore, the clamping assembly includes a fixed block, a movable block, a screw, and a nut that cooperates with the screw. The fixed block is fixedly installed on the T-shaped slider. The screw is horizontally arranged and one end is fixedly connected to the top of the fixed block. The movable block is slidably installed on the screw. A clamping space is formed between the movable block and the fixed block. The reinforcing bar is placed in the clamping space. The movable block abuts against the reinforcing bar under the action of the nut.

[0007] Furthermore, the fixed block and the movable block each have multiple protrusions on the side that are close to each other, and the multiple protrusions are spaced apart in the vertical direction.

[0008] Furthermore, the adjustment assembly includes four connecting rods and four connecting sleeves. One end of each of the four connecting rods is fixedly connected to the four corners of the fixed plate, and the other end is slidably connected to the four connecting sleeves. The end of each connecting sleeve away from the connecting rod is fixedly connected to the four corners of the support plate. The end of each connecting sleeve near the connecting rod has a plurality of first through holes spaced apart in the vertical direction. The connecting rod has a second through hole, and the second through hole is connected to the first through hole by a connecting pin.

[0009] Furthermore, the T-shaped slider is provided with a threaded through hole, and a stop screw is installed in the threaded through hole. When the stop screw is screwed out of the threaded through hole and contacts the T-shaped groove, the T-shaped slider is relatively fixed to the support plate; otherwise, the T-shaped slider slides relative to the support plate.

[0010] Beneficial effects:

[0011] 1. This utility model, through the setting of a support frame including a fixed plate and a support plate, a right-angle bending workbench, and an ohmic bending workbench, can simultaneously realize right-angle bending and ohmic bending operations to meet different usage needs. The right-angle bending workbench and the ohmic bending workbench are detachably connected to the fixed plate via bolts, allowing for quick assembly and disassembly of the bending tool, facilitating movement and portability. Furthermore, the combination of a T-shaped slide, a T-shaped slider, and a clamping assembly allows for direct installation and fixation on a reinforcing mesh, meeting the installation requirements of various support surfaces. Specifically, when the support surface is a planar structure, the clamping assembly can be retracted into the support plate by sliding the T-shaped slider, at which point the support plate provides support and fixation. When the support surface is a reinforcing mesh, due to the presence of reinforcing bar protrusions on the mesh surface, the support plate may tilt or shift due to limited contact area. In this case, the clamping assembly can be extended from the bottom of the support plate by sliding the T-shaped slider, directly clamping and fixing with the longitudinal or transverse reinforcing bars to ensure the stability of the bending tool.

[0012] 2. In this utility model, the setting of limiting holes and limiting bosses can facilitate the quick and easy positioning of right-angle bending worktables and ohmic bending worktables, improve installation efficiency, and facilitate subsequent bolt connection.

[0013] 3. In this utility model, the size of the clamping space can be adjusted by setting a fixed block, a movable block, a screw, and a nut that cooperates with the screw, so as to meet the installation and fixing of steel bars of different sizes and steel mesh with different spacing. Specifically, when the spacing between adjacent steel bars of the steel mesh is greater than the distance between two fixed blocks, the two movable blocks can be used to directly clamp and fix the adjacent steel bars. During this process, the fixed blocks do not need to contact the steel bars. The multiple protrusions can increase the frictional resistance when clamping the steel bars.

[0014] 4. In this utility model, the height of the fixing plate can be adjusted by setting four connecting rods, four connecting sleeves and connecting pins to meet the usage needs of different heights or different space heights; the T-shaped slider can be fixed by setting threaded through holes and stop screws to prevent it from sliding freely.

[0027] This utility model provides a portable round steel bending tool, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a support frame, a right-angle bending workbench 1, and an ohmic bending workbench 2. The right-angle bending workbench 1 and the ohmic bending workbench 2 can bend round steel into standard right-angle bends and standard ohmic bends, meeting the needs of construction sites. Their specific structures can adopt conventional structures found in existing technologies. Furthermore, to avoid interference when both work simultaneously, they can be staggered. Both the right-angle bending workbench 1 and the ohmic bending workbench 2 are detachably connected to the support frame. The support frame includes a fixed plate 3 and a support plate 4. The fixed plate 3 is movably connected to the support plate 4 via the adjusting component 5. The right-angle bending workbench 1 and the ohmic bending workbench 2 are both detachably connected to the fixed plate 3 via bolts. The support plate 4 has multiple T-shaped grooves 6 symmetrically arranged at both ends along the vertical direction. T-shaped sliders 7 are slidably arranged in the T-shaped grooves 6. A clamping component is fixedly installed at one end of the T-shaped slider 7 near the bottom. The clamping component is detachably connected to the reinforcing bar. The clamping component slides out or retracts to the bottom of the support plate 4 under the action of the T-shaped slider 7.

[0028] In this embodiment, the support frame including the fixed plate 3 and the support plate 4, the right-angle bending workbench 1, and the ohmic bending workbench 2 enable simultaneous right-angle and ohmic bending operations to meet different usage requirements. The right-angle bending workbench 1 and the ohmic bending workbench 2 are detachably connected to the fixed plate 3 via bolts, allowing for quick assembly and disassembly of the bending tool for easy movement and carrying. Furthermore, the T-shaped slide 6, the T-shaped slider 7, and the clamping assembly allow for direct installation and fixation on the reinforcing mesh, meeting the installation requirements of various support surfaces. Specifically, when the support surface is a planar structure, the clamping assembly can be retracted into the support plate 4 by sliding the T-shaped slider 7, providing support and fixation. When the support surface is a reinforcing mesh, the support plate 4 may tilt or shift due to limited contact area caused by the protruding reinforcing bars on the mesh surface. In this case, the clamping assembly can be extended from the bottom of the support plate 4 by sliding the T-shaped slider 7, directly clamping and fixing the tool to the longitudinal or transverse reinforcing bars to ensure stability.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the fixing plate 3 is provided with a plurality of limiting holes of different shapes at intervals. The bottom of the right angle bending workbench 1 and the ohmic bending workbench 2 are provided with a plurality of limiting bosses. The right angle bending workbench 1 and the ohmic bending workbench 2 are connected to the limiting holes through the limiting bosses. The position and shape of the limiting holes and the limiting bosses can be set to correspond uniquely. The foolproof design can improve the installation efficiency.

[0030] In this embodiment, the setting of limiting holes and limiting bosses can facilitate quick and easy positioning of the right-angle bending workbench 1 and the ohmic bending workbench 2, improving installation efficiency and facilitating subsequent bolt connection.

[0031] In this utility model, preferably, such as Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly includes a fixed block 8, a movable block 9, a screw 10, and a nut 11 that mates with the screw 10. The fixed block 8 is fixedly mounted on the T-shaped slider 7. The screw 10 is horizontally positioned, and one end is fixedly connected to the top of the fixed block 8. The movable block 9 is slidably mounted on the screw 10. A clamping space is formed between the movable block 9 and the fixed block 8. The reinforcing bar is placed in the clamping space. The movable block 9 abuts against the reinforcing bar under the action of the nut 11. To facilitate locking, a rotating handle can be welded onto the nut 11. Multiple protrusions are provided on the side of the fixed block 8 and the movable block 9 that are close to each other. The multiple protrusions are spaced apart in the vertical direction.

[0032] In this embodiment, the size of the clamping space can be adjusted by setting up the fixed block 8, the movable block 9, the screw 10 and the nut 11 that cooperates with the screw 10, so as to meet the installation and fixing of steel bars of different sizes and steel mesh with different spacing. Specifically, when the spacing between adjacent steel bars of the steel mesh is greater than the distance between the two fixed blocks 8, the two movable blocks 9 can be used to directly clamp and fix the adjacent steel bars. During this process, the fixed block 8 does not need to contact the steel bars. The multiple protrusions can increase the frictional resistance when clamping the steel bars.

[0033] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the adjustment assembly 5 includes four connecting rods 51 and four connecting sleeves 52. One end of each of the four connecting rods 51 is fixedly connected to the four corners of the fixed plate 3, and the other end is slidably connected to the four connecting sleeves 52. The end of each connecting sleeve 52 away from the connecting rods 51 is fixedly connected to the four corners of the support plate 4. The end of each connecting sleeve 52 near the connecting rods 51 has a plurality of first through holes spaced apart in the vertical direction. The connecting rods 51 have second through holes, and the second through holes are connected to the first through holes by connecting pins 53.

[0034] In this embodiment, the height of the fixing plate 3 can be adjusted by setting four connecting rods 51, four connecting sleeves 52 and connecting pins 53 to meet the usage needs of different heights or different space heights.

[0035] In this utility model, preferably, such as Figure 1 and Figure 3 As shown, the T-shaped slider 7 is provided with a threaded through hole, and a stop screw 12 is installed in the threaded through hole. When the stop screw 12 is screwed out of the threaded through hole and contacts the T-shaped sliding groove 6, the T-shaped slider 7 is relatively fixed to the support plate 4. Otherwise, the T-shaped slider 7 slides relative to the support plate 4.

[0036] In this embodiment, the T-shaped slider 7 can be fixed by the threaded through hole and the stop screw 12 to prevent it from sliding freely.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
