Description

Technical Field

[0001] This invention relates to the field of steel cage manufacturing technology, and in particular to an automatic rebar threading and positioning device for longitudinal steel bars in slab-type structural steel cages. Background Technology

[0002] In the industrialized construction of buildings and transportation engineering, there is a large amount of steel bar binding work. For small column components, steel mesh, and steel trusses, there are already automated binding equipment that can achieve rapid automated binding and shaping.

[0003] However, for large components, a large number of closed reinforcing bars are usually installed, and the rebar tying work area is huge, making it difficult to achieve rebar tying and positioning using small automated equipment. Therefore, rebar tying usually occupies a significant portion of the production cycle for large precast components. At the same time, for the convenience of manual rebar threading, pre-cut straight reinforcing bars are generally used. When the length of the reinforcing bars is insufficient, they are lengthened by staggered tying and other methods, resulting in waste of reinforcing bars.

[0004] Therefore, how to improve the binding speed of steel cages for large structural members with closed reinforcing bars and reduce costs has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the present invention provides an automatic rebar threading and positioning device for longitudinal rebars in steel cages of slab components. The purpose is to improve the efficiency of placing and positioning rebars in steel cages of large slab components and reduce rebar loss during the rebar binding process.

[0006] To achieve the above objectives, the present invention discloses an automatic rebar threading and positioning device for longitudinal rebars in a slab-type structural member rebar cage, including a raw material storage device and a rebar binding frame.

[0007] A steel bar straightening and shearing device is provided between the raw material storage device and the steel bar binding frame;

[0008] The rebar straightening and shearing device includes a track, a transport trolley, a rebar straightening machine, and a rebar shearing machine;

[0009] The length of the track covers the width required for the rebar to pass through, and it is set perpendicular to the direction of the rebar passing through.

[0010] The transport trolley is mounted on the track and can move back and forth along the track.

[0011] The rebar straightening machine and the rebar shearing machine are sequentially arranged on the transport trolley along the direction of the rebar threading, and are respectively used to straighten the raw material rebar stored in the raw material storage device and push it into the rebar binding frame, and to cut the raw material rebar after it has been pushed;

[0012] The rebar binding frame includes at least two transverse rebar fixing plates and at least two supporting beams disposed between each pair of transverse rebar fixing plates.

[0013] Each of the transverse reinforcing bar fixing plates is perpendicular to the raw material reinforcing bar pushed into the reinforcing bar binding frame, and each of the raw material reinforcing bars is provided with a first positioning groove on its upper part.

[0014] Each of the supporting crossbeams is arranged parallel to the raw material steel bars and is provided with multiple second positioning grooves for positioning transverse steel bars perpendicular to the raw material steel bars. These grooves are installed on a lifting device and are driven by the lifting device to move back and forth in the vertical direction.

[0015] Preferably, the raw material storage device includes a rotatable rebar feeding reel;

[0016] The rotatable rebar reeling disc is used to hold the raw material rebar in a circular or spiral shape.

[0017] Preferably, each of the first positioning grooves is V-shaped or U-shaped.

[0018] Preferably, the rebar tying frame includes a frame support for fixing all the transverse rebar fixing plates;

[0019] The support frame is connected to each of the transverse steel reinforcement fixing plates via a detachable mechanical connection structure.

[0020] Each of the detachable mechanical connection structures is positioned at any location between the corresponding transverse steel reinforcement fixing plate and the jig support frame.

[0021] More preferably, it includes a variety of transverse reinforcement fixing plates that match different slab member reinforcement cages;

[0022] Each of the aforementioned transverse reinforcing bar fixing plates is connected to the jig support frame via the detachable mechanical connection structure.

[0023] Preferably, the rebar binding frame is equipped with drive wheels that drive the corresponding transverse rebar and / or the corresponding raw material rebar to reciprocate along the length direction.

[0024] The beneficial effects of this invention are:

[0025] Compared with traditional methods, this invention can adapt to the binding of steel cages for slab components of different sizes, and realizes automatic positioning and threading of longitudinal steel bars inside the closed transverse steel bars to reduce and improve the binding efficiency of steel cages for slab components. At the same time, it uses coiled and spiral steel bars to automatically straighten and cut them to reduce the waste of lapped steel bars.

[0026] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

[0035] Example: Figures 1 to 8 As shown, the automatic rebar threading and positioning equipment for longitudinal rebars of slab structural members includes a raw material storage device 1 and a rebar binding frame 3.

[0036] Among them, a steel bar straightening and shearing device 2 is provided between the raw material storage device 1 and the steel bar binding frame 3;

[0037] The rebar straightening and shearing device 2 includes a track 21, a transport trolley 22, a rebar straightening machine 23, and a rebar shearing machine 24;

[0038] The length of track 21 covers the width required for the rebar to pass through, and is set perpendicular to the direction of the rebar passing through;

[0039] The transport trolley 22 is mounted on the track 21 and can move back and forth along the track 21;

[0040] The rebar straightening machine 23 and the rebar shearing machine 24 are arranged sequentially on the transport trolley 22 along the direction of rebar threading, and are respectively used to straighten the raw material rebar stored in the raw material storage device 1 and push it into the rebar binding frame 3, and to cut the raw material rebar after it has been pushed.

[0041] The rebar binding frame 3 includes at least two transverse rebar fixing plates 32 and at least two supporting beams 34 disposed between each pair of transverse rebar fixing plates 32.

[0042] Each transverse steel bar fixing plate 32 is set perpendicularly to the raw steel bar pushed into the steel bar binding frame 3, and each raw steel bar is provided with a first positioning groove on it.

[0043] Each supporting beam 34 is set parallel to the raw material steel bar and is provided with multiple second positioning grooves 35 for positioning transverse steel bars perpendicular to the raw material steel bar. These grooves are set on the lifting equipment 33 and are driven by the lifting equipment 33 to move back and forth in the vertical direction.

[0044] The principle of this invention is as follows: the steel bar straightening machine 23 can straighten the raw steel bars stored in the raw material storage device 1 and push them into the steel bar binding frame 3; the steel bar shearing machine 24 can cut the raw steel bars after each delivery of a given length, ensuring that the length of each raw steel bar cut meets the requirements of the steel cage.

[0045] The transport trolley 22 can stop the rebar straightening machine 23 and the rebar shearing machine 24 at a designated position and push the raw rebar.

[0046] After all the raw material steel bars have been pushed onto the transverse steel bars on all the supporting beams 34, they can be moved to the top or bottom surface by the lifting device 33 to prepare for the subsequent rebar threading of the raw material steel bars.

[0047] In some embodiments, the raw material storage device 1 includes a rotatable rebar feeding reel 11;

[0048] The rotatable rebar reeling tray 11 is used to hold round or spiral-shaped raw rebar.

[0049] In practical applications, the raw steel bars in the shape of coils or spirals are not limited by the length of the finished steel bars. Even for long plates, multiple steel bars do not need to be overlapped, which reduces the waste of steel bars caused by construction.

[0050] In some embodiments, each first positioning groove is V-shaped or U-shaped.

[0051] In some embodiments, the rebar binding jig 3 includes a jig support frame 31 for fixing all transverse rebar fixing plates 32;

[0052] The support frame 31 is connected to each transverse steel reinforcement fixing plate 32 via a detachable mechanical connection structure;

[0053] Each detachable mechanical connection structure is located at any position between the corresponding transverse steel reinforcement fixing plate 32 and the jig support frame 31.

[0054] In some embodiments, a variety of transverse reinforcing bar fixing plates 32 are included to match different plate-type member reinforcing cages;

[0055] Each type of transverse steel reinforcement fixing plate 32 is connected to the jig support frame 31 via a detachable mechanical connection structure.

[0056] In practical applications, by setting a detachable mechanical connection structure at any position between the transverse steel bar fixing plate 32 and the frame support 31, each transverse steel bar fixing plate 32 is connected to the frame support 31, so that the frame support 31 can set various transverse steel bar fixing plates 32 at any position. For various transverse steel bar fixing plates 32 that match different plate-type component steel cages, the appropriate position can be selected to fix the transverse steel bar fixing plate 32.

[0057] In some embodiments, the rebar binding jig 3 is provided with drive wheels that drive the corresponding transverse rebar and / or the corresponding raw material rebar to reciprocate along the length direction.

[0058] In practical applications, the drive wheel can ensure that the corresponding transverse reinforcing bars and / or the corresponding raw material reinforcing bars are repositioned in the length direction after being cut.

[0059] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
