Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a rebar straightening device for building construction. Background Technology

[0002] In the field of building construction, steel bars are a critical structural material, and their quality directly affects the safety and durability of buildings. Because steel bars are prone to bending and deformation during transportation, storage, and processing, they need to be straightened using steel bar straightening devices to restore their straightness to meet construction specifications.

[0003] Existing rebar straightening devices mainly consist of a frame, two rows of parallel straightening rollers, a power transmission system, and a control system. The rebar enters the gap between the straightening rollers through the feed inlet and is straightened under the squeezing and rolling friction of the upper and lower rollers.

[0004] Existing rebar straightening devices typically focus only on the straightening process, with only a simple discharge port at the end of the frame. They lack components for receiving and guiding the straightened rebar, and there is no buffer or transmission equipment connecting the discharge port to the ground. This causes the rebar to lose restraint and fall directly after leaving the straightening rollers, resulting in scratches, dents, and other damage to the rebar surface. Furthermore, it requires additional personnel to pick up and transport the rebar, increasing workload and delaying progress. Therefore, we propose a rebar straightening device for building construction to effectively address these shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a steel bar straightening device for building construction, which solves the problem mentioned in the background art of the lack of a receiving and guiding component for the straightened steel bar.

[0006] This utility model is achieved through the following technical solution: a rebar straightening device for building construction, comprising a straightening machine body, and further comprising:

[0007] A frame is provided at the tail end of the correction machine body and is arranged along the length direction of the correction machine body;

[0008] Several receiving platforms are fixed on the frame and are evenly spaced along the length of the frame. The top surface of each receiving platform is lower than the discharge port height of the straightening machine body. Each receiving platform has an inclined structure on one side.

[0009] Several limiting rods are provided, each corresponding to a receiving platform. Each limiting rod is movably mounted on the top of its corresponding receiving platform and can move along the length of the receiving platform.

[0010] Optionally, the limiting rod is an L-shaped structure, which, together with the receiving platform, forms a C-shaped opening, with the opening of the C-shaped opening facing the inclined structure.

[0011] Optionally, the top of the receiving station has a strip-shaped opening along its length, and the lower end of the limiting rod slides within the strip-shaped opening;

[0012] An adjusting rod is fixed at the lower end of each limiting rod. A strip hole is provided on the side wall of each receiving platform for the adjusting rod to move through. Locking knobs are screwed on both ends of the adjusting rod.

[0013] Optionally, a stop bar is movably installed between two adjacent receiving stations, and a drive mechanism is provided on the frame to drive each stop bar to retract or extend.

[0014] Optionally, the drive mechanism includes a rotating shaft rotatably connected to the frame, the rotating shaft moving along the length of the frame through each receiving station, and a servo motor connected to the rotating shaft for transmission is mounted on the frame; each stop bar is fixed on the rotating shaft.

[0015] Compared with the prior art, the present invention provides a rebar straightening device for building construction, which has the following beneficial effects:

[0016] In this invention, the receiving platforms work together to form a continuous receiving surface. When the straightened steel bar leaves the straightening machine body, it will be received by each receiving platform, avoiding surface scratches, dents and other damage caused by free fall, and effectively protecting the mechanical properties of the steel bar.

[0017] Meanwhile, the limiting rods ensure that the steel bars roll down the inclined structure of the receiving platform under the action of gravity into the prepared transfer vehicle, eliminating the need for secondary manual picking and handling, significantly reducing the labor intensity of workers and greatly improving construction efficiency.

[0023] 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.

[0024] Please see Figures 1 to 4 A rebar straightening device for building construction includes a straightening machine body 1, used to straighten rebar. This is prior art and will not be described in detail here.

[0025] This embodiment also includes: a frame 2, several receiving platforms 3 and several limiting rods 4, to solve the problem of the lack of receiving and guiding components for the straightened steel bars in the prior art.

[0026] Specifically, the frame 2 is located at the tail end of the straightening machine body 1 and is arranged along the length of the straightening machine body 1 to provide support for other components in the device. Several receiving platforms 3 are fixed to the frame 2 and are evenly spaced along the length of the frame 2, thus forming a continuous receiving surface. The top surface of each receiving platform 3 is lower than the discharge port height of the straightening machine body 1, enabling it to receive the straightened rebar and prevent it from falling directly to the ground. An inclined structure is provided on one side of each receiving platform 3. A transfer cart (not shown in the diagram) is parked on the ground at the lower end of the inclined structure. The received rebar can roll down the inclined structure into the transfer cart, eliminating the need for manual secondary handling.

[0027] With the above design, the reinforcing bars are inserted into the feed port of the straightening machine body 1 for straightening; then, the receiving platform 3 receives the reinforcing bars discharged from the discharge port of the straightening machine body 1; until the reinforcing bars are completely straightened, the reinforcing bars roll down the inclined structure of the receiving platform 3 into the prepared transfer vehicle, thereby preventing the reinforcing bars from falling to the ground, and eliminating the need for manual secondary picking and handling.

[0028] In addition, several limiting rods 4 correspond one-to-one with several receiving platforms 3. Each limiting rod 4 is movably mounted on the top of its corresponding receiving platform 3. Each limiting rod 4 can move along the length of the receiving platform 3, thereby adjusting the length of the top surface of the receiving platform 3 so that steel bars of different diameters can roll smoothly down the inclined structure. This prevents the steel bars from remaining on the top surface of the receiving platform 3 or rolling down from non-inclined structures.

[0029] It is worth mentioning that the limiting rod 4 has an L-shaped structure. The L-shaped structure and the receiving platform 3 cooperate to form a C-shaped opening. The opening of the C-shaped opening faces the inclined structure so that the receiving steel bar can only roll in the direction of the inclined structure.

[0030] In order to adjust the position of the limit rod 4, the following design is adopted:

[0031] The top of the receiving platform 3 has a strip-shaped opening 5 along its length, and the lower end of the limiting rod 4 slides within the strip-shaped opening 5. When the limiting rod 4 moves along the length of the strip-shaped opening 5, the length of the top surface of the receiving platform 3 can be adjusted so that the length of the top surface of the receiving platform 3 used to receive the reinforcing bar is less than the diameter of the reinforcing bar, so that the reinforcing bar can roll smoothly onto the inclined structure.

[0032] In addition, an adjusting rod 6 is fixed to the lower end of each limiting rod 4. A strip-shaped hole 7 is provided on the side wall of each receiving platform 3 for the adjusting rod 6 to pass through, and the strip-shaped hole 7 is parallel to the strip-shaped opening 5. Locking knobs 8 are screwed onto both ends of the adjusting rod 6. When the position of the adjusting rod 6 needs to be adjusted, first loosen the locking knob 8, and then slide the adjusting rod 6 along the strip-shaped hole 7 to adjust the position of the limiting rod 4. After adjustment, tighten the locking knob 8 to fix the position of the limiting rod 4.

[0033] In another embodiment of this application, a stop bar 9 is movably arranged between two adjacent receiving stations 3, and a drive mechanism 10 is provided on the frame 2 for driving each stop bar 9 to retract or extend. When each stop bar 9 is retracted, the reinforcing bars can roll normally down the inclined structure into the transfer vehicle. When the transfer vehicle is full of reinforcing bars and needs to be transferred, the stop bar 9 extends to form a certain angle with the inclined structure. At this time, the reinforcing bars can be left on the inclined structure, which facilitates the transfer of the transfer vehicle or the replacement of a new transfer vehicle; at the same time, the correction work can continue without stopping the machine.

[0034] In this embodiment, the drive mechanism 10 includes a rotating shaft 101 rotatably connected to the frame 2. The rotating shaft 101 moves along the length of the frame 2 through each receiving station 3. A servo motor 102, which is drivenly connected to the rotating shaft 101, is mounted on the frame 2. Each stop bar 9 is fixed on the rotating shaft 101. When the servo motor 102 is working, it can drive the rotating shaft 101 to rotate, thereby causing each stop bar 9 to unfold or retract.
