Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, and in particular to a rectangular steel pipe rotary guide reinforcing bar system and method. Background Art

[0002] Traditional methods of threading steel bars into rectangular steel tubes mostly involve manually threading the steel bars into the holes on both sides of the rectangular steel tube. Since the surface of the steel bars is uneven and the holes on the rectangular steel tubes are generally not finely polished, the inner walls of the holes on the rectangular steel tubes are not smooth, and there are certain burrs on the inner walls of the holes. This makes it easy for the steel bar surface and the inner wall of the hole to get stuck during the threading process, which reduces the threading efficiency. At the same time, when the steel bars pass through the first hole into the rectangular steel tube, manual threading cannot ensure that the radial movement path of the steel bars remains unchanged, which makes it easy for the steel bars to hit the inner wall of the rectangular steel tube when passing through the second hole of the rectangular steel tube, further causing the steel bars to get stuck during the threading process, which reduces the efficiency of the steel bars.

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 9 The present invention provides a technical solution: a rectangular steel tube rotary guide reinforcing bar system, comprising a mounting platform 11, a rectangular steel tube 12 and a plurality of steel bars 13, wherein the rectangular steel tube 12 is fixedly clamped on the upper end of the mounting platform 11, and a plurality of groups of through holes 14 arranged in a rectangular array are transversely opened at the same position of the left and right side walls of the rectangular steel tube 12, and the steel bars 13 are used to penetrate the rectangular steel tube 12 through the same group of through holes 14, and further comprising a guide mechanism with the same number as the number of the groups of through holes 14, wherein the plurality of guide mechanisms are respectively arranged on the left side of each group of through holes 14; the upper end of the mounting platform 11 is located at the rear end of the rectangular steel tube 12 and is vertically fixedly connected with a third mounting frame 15, and the first mounting rods 16 are longitudinally arranged on the left and right sides above the same row of through holes 14 in the rectangular steel tube 12. and a second mounting rod 17; the ends of the first mounting rod 16 and the second mounting rod 17 are fixedly connected to the third mounting frame 15, and a guide cylinder is provided at each group of through holes 14 below the second mounting rod 17, and a feeding mechanism is provided on the right side of each group of through holes 14, and a rotating mechanism is provided on the right side of the feeding mechanism, and a steel bar 13 is clamped horizontally in the rotating mechanism; the guide mechanism is used to guide the depth of subsequent insertion of the steel bars 13, the guide cylinder is used to limit the radial movement path of the steel bars 13 in the rectangular steel pipe, the feeding mechanism is used to assist the steel bars 13 to be inserted into the through holes 14 on the right side of the rectangular steel pipe 12, and the rotating mechanism is used to drive the steel bars 13 to feed, and to rotate the steel bars 13 when a jam occurs during the insertion of the steel bars 13.

[0032] The plurality of rotating mechanisms jointly drive the steel bars 13 held by themselves to be inserted into the corresponding through-holes 14 on the right side of the rectangular steel tube 12; in this process, the steel bars 13 are first aligned and inserted into the corresponding through-holes 14 on the right side of the rectangular steel tube 12 by the corresponding feeding mechanisms, and then when the steel bars 13 are inserted into the rectangular steel tube 12, they are directly inserted into the through-holes 14 on the left side of the rectangular steel tube 12 under the limiting and guiding action of the guide cylinder, and the insertion depth of the steel bars 13 is limited by the guide mechanism; then, after the insertion of the steel bars 13 is completed, the steel bars 13 are inserted into the through-holes 14 on the left side of the rectangular steel tube 12. The steel bar 13 is cut off by an external cutting device, and then the rectangular steel tube 12 with the reinforcement inserted is removed from the mounting platform 11, and finally a new rectangular steel tube 12 is clamped on the mounting platform 11 for a new round of reinforcement insertion. It should be noted that in the process of reinforcing the steel bar 13, if the steel bar 13 and the inner wall of the perforation 14 are stuck, the rotating mechanism will drive the steel bar 13 to rotate, and the clamping points of the steel bar 13 and the perforation 14 are dislocated from each other by rotation, so that the steel bar 13 can be inserted smoothly.

[0033] The present invention guides and limits the path and depth of the entire insertion process of the steel bar 13 through a feeding mechanism, a guide cylinder and a guide mechanism, and at the same time utilizes a rotating mechanism to release the jam when the steel bar 13 is stuck, thereby making the reinforcing bar insertion process of the steel bar 13 more accurate and efficient, thereby effectively improving the reinforcing bar insertion work of the rectangular steel pipe 12.

[0034] As a further solution of the present invention, the guide mechanism includes a guide rod 21, and the guide rod 21 is composed of a first column 211 and a second column 212 respectively located on the left and right sides. The outer diameter of the first column 211 is the same as the inner diameter of the through hole 14, and the outer diameter of the second column 212 is smaller than the inner diameter of the through hole 14. The first column 211 and the second column 212 are transitioned by a chamfer; the upper end of the mounting platform 11 is located on the left side of the rectangular steel pipe 12 and is provided with a first mounting block 22 that can be horizontally slidably connected to the mounting platform 11. The first mounting block 22 is horizontally provided with a receiving groove 23 corresponding to each guide column position. The guide rods 21 are respectively connected to the corresponding receiving grooves 23 for transverse sliding. A first connecting plate 24 is arranged on the left side of the first mounting block 22. A first cylinder 25 is arranged on the left side of the first connecting plate 24. The first cylinder 25 is used to drive the first connecting plate 24 to move transversely. A first connecting rod 26 is fixedly connected to the corresponding receiving groove 23 on the right side of the first connecting plate 24. The first connecting rod 26 penetrates the first mounting block 22 and is fixedly connected to the left end of the corresponding guide rod 21. The receiving groove 23 is connected inside and outside with a limiting mechanism, and the limiting mechanism is used to control the maximum depth of the guide rod 21 retracted into the receiving groove 23.

[0035] Pushed by the first cylinder 25, each guide rod 21 passes through the corresponding set of perforations 14 to the right side of the rectangular steel pipe 12, and then the first cylinder 25 stops working; then, during the insertion of the steel bar 13, the left end of the steel bar 13 pushes the right end of the guide rod 21, so that the guide rod 21 is retracted into the accommodating groove 23, until the guide rod 21 moves to the left to the maximum depth, at which time the steel bar 13 cannot continue to move left; correspondingly, the steel bar 13 reaches the maximum insertion depth at this time; then, when the reinforcement is inserted, the first mounting block 22 is controlled to move to the left to expose the steel bar 13 inserted into the accommodating groove 23; so that the rectangular steel pipe 12 after the reinforcement is inserted can be separated from the mounting platform 11 with the steel bars 13 thereon.

[0036] As a further solution of the present invention, the guide cylinder includes a first rotating shaft 31 which is laterally arranged below the second mounting rod 17, the upper end of the first rotating shaft 31 is fixedly connected to a first connecting rod 32, the upper end of the first connecting rod 32 is connected to a calibration mechanism, the calibration mechanism is arranged below the second mounting rod 17, the front and rear sides of the first rotating shaft 31 are symmetrically and elastically rotatably connected to a first semi-cylinder 33, the left ends of the first semi-cylinder 33 are fixedly connected to a semi-conical cylinder 34, the left ends of the semi-conical cylinder 34 are fixedly connected to a second semi-cylinder 35, the first semi-cylinder 33 is provided with a clamping mechanism, the clamping mechanism is used to control the merging of the two first semi-cylinders 33 and the two second semi-cylinders 35, the inner diameter of the second semi-cylinder 35 is the same as the inner diameter of the perforation 14, and the inner diameter of the first semi-cylinder 33 is larger than the inner diameter of the perforation 14; the calibration mechanism is used to control the two first semi-cylinders 33 to be concentric with the perforation 14 after splicing.

[0037] In the initial state, the two first semi-cylinders 33 with the semi-conical cylinders 34 and the second semi-cylinders 35 connected thereto are in an open state, so that there is no obstacle between the corresponding set of through holes 14; then, when the guide rod 21 crosses to the right side of the rectangular steel tube 12, the clamping mechanism controls the two first semi-cylinders 33 to close and splice, and the two first semi-cylinders 33 with the semi-conical cylinders 34 and the second semi-cylinders 35 connected thereto are closed and spliced; the two first semi-cylinders 33 together form a circular channel with an inner diameter greater than the inner diameter of the through hole 14, and the two second semi-cylinders 35 together form a circular channel with an inner diameter the same as the inner diameter of the through hole 14. The channels transition through the inner wall of the semi-conical cylinder 34; at the same time, under the action of the calibration mechanism, the two circular channels are concentric with the through-hole 14, and the circular channel formed by the two second semi-cylinders 35 coincides with the through-hole 14; then, during the insertion process, the steel bar 13 is guided by the first semi-cylinder 33 and the semi-conical cylinder 34 to enter the inner walls of the two second semi-cylinders 35, and the steel bar 13 directly passes through the through-hole 14 on the left side through the guiding and limiting action of the second semi-cylinder 35; finally, when the reinforcing bar insertion work is completed, the guide cylinder is reset, and the rectangular steel pipe 12 can be separated from the mounting platform 11 by longitudinal movement.

[0038] The present invention provides a group of openable and closable first semi-cylinder 33, semi-conical cylinder 34 and second semi-cylinder 35, so that during the insertion of the steel bars 13, the steel bars 13 can directly pass through the left-side through hole 14 under the guidance of the first semi-cylinder 33, semi-conical cylinder 34 and second semi-cylinder 35, making the entire reinforcing bar insertion process more efficient. At the same time, since the first semi-cylinder 33, semi-conical cylinder 34 and second semi-cylinder 35 can be opened and closed, after the reinforcing bar insertion is completed, the rectangular steel pipe 12 can leave the equipment with the steel bars 13 thereon without obstacles.

[0039] As a further solution of the present invention, the clamping mechanism includes two second connecting rods 41 hinged to each other at the upper ends, and the lower ends of the second connecting rods 41 are rotatably connected to the left ends of the two first semi-cylinders 33 respectively; a second mounting plate 49 is horizontally arranged above the first rotating shaft 31, and the second mounting plate 49 is fixedly connected between the first mounting rod 16 and the second mounting rod 17, and the lower end of the second mounting plate 49 is located above the second connecting rod 41 and is vertically fixedly connected to a limiting rod 410, and the lower ends of the limiting rods 410 are slidably connected to the corresponding second connecting rods 41, and the hinges of the two second connecting rods 41 are horizontally fixedly connected with a second connecting rod 42, and the left end of the second connecting rod 42 is fixedly connected to a vertical A trigger rod 43 is set, and a connecting block 44 is set above the trigger rod 43, and the connecting block 44 is fixedly connected to the upper end of the first mounting rod 16, and the lower end of the connecting block 44 is fixedly connected to a vertically set sliding rod 45, and the sliding rod 45 is vertically slidably connected to the trigger rod 43, and a control rod 46 is laterally slidably connected to the left side of the first mounting rod 16, and the control rod 46 is laterally fixedly connected to a third connecting rod 47 corresponding to the front side of the trigger rod 43, and the third connecting rod 47 is elastically rotatably connected to a tongue piece 48, and the tongue piece 48 can limit the upward movement of the trigger rod 43; the trigger rod 43 is externally connected with a self-locking mechanism, and the self-locking mechanism is used to fix the trigger rod 43 to the first mounting rod 16.

[0040] As the guide rod 21 moves to the right and passes through the rectangular steel tube 12, first, the chamfer on the guide rod 21 is squeezed with the lower end of the trigger rod 43, causing the trigger rod 43 to move upward, and further causing the trigger rod 43 to drive the upper ends of the two second connecting rods 41 to move upward. Under the limiting action of the limit rod 410, the two second connecting rods 41 are clamped together, and then the two second connecting rods 41 drive the two first semi-cylinders 33 to close and splice, so that the two second semi-cylinders 35 are closed to each other, until the first column 211 of the guide rod 21 moves to the lower end of the trigger rod 43, at which time the first semi-cylinder 33 and the second semi-cylinder 35 are completely closed respectively; at this time, the inner walls of the two second semi-cylinders 35 fit the outer wall of the first column 211; in this process, under the action of the adjustment mechanism, the first rotating shaft 31 can change its position, so that the inner walls of the two second semi-cylinders 35 can fit the outer wall of the first column 211, and further the inner wall of the second semi-cylinder 35 is aligned with the inner wall of the left through hole 14.

[0041] The present invention squeezes the trigger rod 43 by the guide rod 21 to make the inner walls of the two second semi-cylinders 35 fit the first column 211, and uses the fitting process to cooperate with the adjustment mechanism to correct the axial position of the second semi-cylinder 35, further ensuring that the inner wall of the second semi-cylinder 35 is aligned with the inner wall of the left through hole 14.

The inner wall of the cylindrical tube 51 on the left side is laterally slidably connected with a sleeve 53, and the left end of the sleeve 53 is fixedly connected with a push rod 54, and the left end of the push rod 54 passes through the left sleeve 53 and extends to the left side of the sleeve 53.
