When using the forming equipment, a discharge mechanism is required to be used in conjunction with the discharge. The discharge mechanism consists of a support plate, a fixed frame and a discharge frame. The coiled steel bars need to be put on the outside of the discharge frame. The staff first uses a trailer to drag the coiled steel bars horizontally to the discharge frame, and then removes the discharge frame from the fixed frame, and manually inserts the discharge frame horizontally into the hollow position of the coiled steel bars. Then the staff needs to use a trailer to The vehicle rotates the unloading rack to be vertical, so that the coiled steel bars are also in a vertical state, and then the trailer is used to lift the unloading rack and the coiled steel bars upward, and the unloading rack and the coiled steel bars are transported to the top of the fixed rack, and then the unloading rack and the coiled steel bars are slowly lowered by the trailer, so that the unloading rack and the fixed rack are assembled together. In summary, before making the assembled steel truss floor deck, there are many steps to place the steel bars into the unloading mechanism, which will affect the forming efficiency of the assembled steel truss floor deck. Now a device and method for forming an assembled steel truss floor deck that is convenient for unloading is developed. Summary of the Invention

[0008] Further explanation: an electromagnet is also included. The electromagnet is arranged in the protective frame and is used to fix the steel bars by magnetic adsorption.

[0009] Further explanation: there is also a protective mechanism to prevent the rolled steel bars from spreading out. The protective mechanism includes a protective plate, which is connected to the top of the rotating frame. The top of the protective frame is rotatably connected to a support rod, the support rod is connected to the protective plate, and a moving rod is slidably connected to the protective plate. A protective net is connected between the moving rod and the support rod, and an extrusion spring is connected between the moving rod and the support rod.

[0013] A method for forming an assembled steel truss floor deck comprises the following steps: S1: The electric push rod controls the movement of the sliding frame to drive the fixed frame and the unloading frame to rotate clockwise, and the unloading frame rotates to a horizontal state.

[0016] According to the present invention, during the clockwise rotation of the unloading rack, the movable rack is pulled by connecting the pull rope, so that the extrusion column pushes the four wedge-shaped racks toward each other, thereby bringing the limiting racks together. Afterwards, when the coiled steel bars pass through the unloading rack and the unloading rack rotates counterclockwise to reset, the extrusion column loosens the wedge-shaped rack, thereby causing the limiting racks to move toward the side away from each other to center the coiled steel bars and simultaneously restrict the coiled steel bars to prevent the coiled steel bars from tilting.

[0017] The invention drives a small gear and a large gear to rotate through a driving motor, and the large gear drives a protection frame and a material unwinding rack to rotate. The material unwinding rack rotates at a constant speed so that the steel bars can be pulled out at a constant speed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0032] Example 1: A fabricated steel truss floor deck forming device, such as Figures 1-4As shown, it includes a forming machine 1, a support plate 11, a fixed frame 12, a protective frame 121, a discharge frame 13, a fixed seat 14, a rotating frame 15, a sliding frame 16, an electric push rod 17, a fixing part 18 and a rotating ring 19. The supporting plate 11 is welded to the lower right part of the forming machine 1, the fixed seat 14 is welded to the right part of the support plate 11, the rotating frame 15 is rotatably connected to the fixed seat 14, the left part of the rotating frame 15 is fixedly connected to the fixed frame 12, and the top middle part of the fixed frame 12 is rotatably connected to the protective frame 121. The height of the protective frame 121 is the height of the discharge frame 13. A quarter of the degree, the protective frame 121 surrounds the bottom of the coiled steel bars to limit the steel bars, so as to avoid the coiled steel bars from tilting when placed vertically. A material discharging rack 13 is welded to the middle of the top of the protective frame 121, and a fixing part 18 is connected to the upper left part of the support plate 11. The front and rear sides of the fixing part 18 are connected to the electric push rod 17, and the front and rear sides of the fixing frame 12 are slidably connected to the sliding frame 16. The sliding frame 16 is rotatably connected to the rotating ring 19, and the left part of the rotating ring 19 is fixed to the right part of the electric push rod 17.

[0033] When using the present assembled steel bar truss floor deck forming device to make an assembled steel bar truss building, the coiled steel bars need to be placed on the unloading rack 13 first. The staff can first control the extension of the telescopic rod of the electric push rod 17 to drive the sliding rack 16 to slide along the axial direction of the telescopic rod of the electric push rod 17. The telescopic rod of the electric push rod 17 drives the sliding rack 16 to move. The movement of the sliding rack 16 drives the fixed rack 12 and the rotating rack 15 to rotate 90 degrees clockwise, so that the unloading rack 13 rotates 90 degrees clockwise. Then, the staff uses a trailer to drag the coiled steel bars horizontally to the unloading rack 13 and put the coiled steel bars on the unloading rack 13. Then, the staff controls the shortening of the telescopic rod of the electric push rod 17 to drive the rotating rack 15 to rotate 90 degrees clockwise. 19 and the sliding frame 16 slide to the direction close to the side of the electric push rod 17 to reset, thereby driving the fixed frame 12, the rotating frame 15 and the unloading frame 13 to rotate counterclockwise to reset, so that the unloading frame 13 can rotate the rolled steel bars into a vertical state, so that there are fewer steps to place the rolled steel bars on the unloading frame 13, which is more convenient for unloading. Then, one end of the rolled steel bars is pulled into the forming machine 1, and the forming machine 1 is turned on. The forming machine 1 can automatically produce assembled steel truss floor decking. During the production process, the forming machine 1 will pull the rolled steel bars to the left. When the rolled steel bars are pulled out, the rolled steel bars will rotate, and the rolled steel bars will drive the protective frame 121 and the unloading frame 13 to rotate. After the production is completed, the forming machine 1 is closed.

[0034] Example 2: Based on Example 1, Figure 5-Figure 8As shown, it also includes a limiting mechanism for limiting the rolled steel bars, the limiting mechanism includes a limiting frame 2, a guide frame 21, a limiting spring 22 and an extrusion assembly, a guide frame 21 is welded in the middle of the bottom of the unloading frame 13, and the four sides of the upper front, back, left and right of the guide frame 21 are slidably connected with the limiting frame 2 for limiting the rolled steel bars, two limiting springs 22 are connected between the limiting frame 2 and the upper part of the guide frame 21, and an extrusion assembly for pushing the limiting frame 2 is provided between the support plate 11 and the guide frame 21; the extrusion assembly includes a moving frame 23, a wedge frame 24, a connecting rope 25, a reset spring 26, a winding seat 27, a fixed disk 28, a rotating frame 29, a reset torsion spring 210 and an extrusion column 211, the moving frame 23 is slidably connected to the guide frame 21, the wedge frame 24 is connected on the side close to each other at the lower part of the limiting frame 2, and the four sides of the top of the moving frame 23 are connected to the extrusion The column 211, the wedge frame 24 and the extrusion column 211 are squeezed together, and a return spring 26 is connected between the lower part of the mobile frame 23 and the bottom of the protective frame 121. The outer side of the lower part of the mobile frame 23 is rotatably connected to the fixed plate 28. The purpose of the rotatable connection between the lower part of the mobile frame 23 and the fixed plate 28 is to drive the unloading frame 13 to rotate during the process of pulling out the steel bars. The rotation of the unloading frame 13 will drive the mobile frame 23 to rotate. Since the lower part of the mobile frame 23 and the fixed plate 28 are rotatably connected, the rotation of the mobile frame 23 will not drive the fixed plate 28 to rotate, so that the fixed plate 28 will not affect the operation of the mobile frame 23. A winding seat 27 is welded to the left part of the fixed plate 28, and a rotating frame 29 is rotatably connected to the winding seat 27. A return torsion spring 210 is connected between the front of the rotating frame 29 and the winding seat 27. A connecting rope 25 is wound around the rear of the rotating frame 29, and the end of the connecting rope 25 is connected to the support plate 11.

[0035] Since the area of ​​the hollow position of the rolled steel bar is generally larger than the circumferential area of ​​the unloading rack 13, after the hollow position of the rolled steel bar passes through the unloading rack 13, the unloading rack 13 rotates counterclockwise to drive the rolled steel bar to a vertical state. There is still some distance between the hollow position of the rolled steel bar and the unloading rack 13, and the rolled steel bar is prone to tilting. The tilting of the rolled steel bar is likely to affect the unloading. Therefore, a limiting mechanism is provided to limit the rolled steel bar to prevent the rolled steel bar from tilting. In the process of the fixed frame 12 driving the protective frame 121 and the unloading rack 13 to rotate clockwise, the unloading rack 13 will drive the guide frame 21, the limiting frame 2 and the movable frame 23 to rotate clockwise as well. The movable frame 23 rotates clockwise to drive the fixed disk 28 and the winding seat 27 and the rotating frame 29 also rotate clockwise together. During the clockwise rotation of the winding seat 27 and the rotating frame 29, since one end of the connecting rope 25 is fixedly connected to the support plate 11, the winding seat 27 will rotate the rotating frame 29 to relax the connecting rope 25 when it rotates clockwise, and the reset torsion spring 210 will be twisted. When the unloading frame 13 rotates clockwise to 75 degrees, the connecting ropes 25 on the rotating frame 29 are all relaxed, and the connecting ropes 25 are straightened. At this time, the rotating frame 29 can no longer rotate, and the rotating frame 29 will be pulled by the connecting rope 25. The rotating frame 29 will drive the winding seat 27 and the fixed plate 28 to move closer to the fixed frame 12. The fixed plate 28 drives the movable frame 23 to move closer to the fixed frame 12. The movement is carried out, the return spring 26 is stretched, the protective frame 121 drives the extrusion column 211 to move toward the side close to the fixed frame 12, and the extrusion column 211 contacts and squeezes the wedge frame 24, so that the four wedge frames 24 move toward the side close to each other, and the wedge frame 24 drives the limiting frame 2 to move toward the side close to each other, and the limiting spring 22 is compressed. In this way, the middle parts of the four limiting frames 2 are gathered together, and after the unloading frame 13 rotates clockwise to 90 degrees, the coiled steel bars can be passed through the unloading frame 13. At this time, the four limiting frames 2 will not affect the coiled steel bars from passing through the unloading frame 13. Afterwards, in the process of the unloading frame 13 rotating counterclockwise to reset and drive the coiled steel bars to rotate into a vertical state, the unloading frame 13 guide frame 21, the limiting frame 2 and the moving frame 23 rotates counterclockwise to reset, and the movable frame 23 rotates counterclockwise to drive the fixed disk 28, the winding seat 27 and the rotating frame 29 to rotate counterclockwise to reset. Under the action of the reset spring 26, the movable frame 23 will be driven to move to the side away from the fixed frame 12 to reset. The movable frame 23 drives the fixed disk 28 and the extrusion column 211 to move to the side away from the fixed frame 12 to reset. After the extrusion column 211 and the wedge frame 24 are separated, under the action of the limiting spring 22, the four limiting frames 2 will be driven to reset to the side away from each other to limit the inside of the rolled steel bars. In this way, the rolled steel bars can be automatically centered by the limiting frame 2 to avoid tilting of the rolled steel bars. Under the action of the reset torsion spring 210, the rotating frame 29 will be driven to reverse and reset the reeling connecting rope 25.

[0036] like Figure 9 As shown, it also includes a driving mechanism for driving the discharge rack 13 to rotate, and the driving mechanism includes a fixed block 3, a driving motor 31, a small gear 32 and a large gear 33. The driving motor 31 is provided at the right front part of the fixed frame 12 through the fixed block 3. The driving motor 31 and the forming machine 1 are electrically connected through the control module. The output shaft of the driving motor 31 is connected to the small gear 32 through a coupling. The large gear 33 is welded circumferentially on the outside of the protective frame 121, and the large gear 33 and the small gear 32 are engaged.

[0037] In the process of forming the assembled steel bar truss floor deck by the forming machine 1, the rolled steel bars will be slowly pulled out, and the rolled steel bars will rotate due to the inertia of pulling, and the rolled steel bars will drive the unwinding rack 13 to rotate as well. The unwinding rack 13 rotates by the inertia of the steel bars being pulled out. It is easy for the unwinding rack 13 to rotate too slowly or too quickly due to the factors of the steel bars. The unwinding rack 13 will affect the unwinding if the speed is too fast or too slow. The factors of the steel bars, for example, when the steel bars are made into rolled steel bars, there may be uneven winding of the steel bars, resulting in uneven unwinding of the steel bars. The rolled steel bars are partially heavier or lighter, which can easily lead to uneven rotation speed of the discharge rack 13 when the rolled steel bars are pulled out. Therefore, a driving mechanism is set. When the forming machine 1 is working, the driving motor 31 will also start working. The driving motor 31 drives the small gear 32 to rotate, and the small gear 32 drives the large gear 33 to rotate. The large gear 33 drives the protective frame 121 and the discharge rack 13 to rotate. When the discharge rack 13 rotates, it will rotate at a uniform speed so that the steel bars can be pulled out at a uniform speed. When the forming machine 1 is working, the driving motor 31 also stops working.

[0038] like Figure 9 As shown, an electromagnet 34 is also included. The lower part of the protective frame 121 is provided with an electromagnet 34. The electromagnet 34 is used to fix the lower side of the steel bar by magnetic adsorption. During the process of the forming machine 1 making the assembled steel bar truss floor deck, the rolled steel bar will be slowly pulled out, and the lower side of the rolled steel bar will be adsorbed and fixed by the electromagnet 34, so that the steel bar will be discharged more smoothly.

[0039] like Figure 10-11 As shown, it also includes a protective mechanism to prevent the rolled steel bars from spreading out, and the protective mechanism includes a protective plate 4, a support rod 41, a protective net 42, a moving rod 43 and an extrusion spring 44. The top of the rotating frame 15 is connected to the protective plate 4, the top of the protective frame 121 is rotatably connected to the support rod 41, the right part of the support rod 41 is connected to the protective plate 4, the protective plate 4 is slidably connected to the moving rod 43, the protective net 42 is connected between the bottom of the moving rod 43 and the support rod 41, and the extrusion spring 44 is connected between the right side of the bottom of the moving rod 43 and the support rod 41.

[0040] like Figure 11As shown, it also includes balls 45. The top of the moving rod 43 is rotatably connected to multiple balls 45 distributed at equal intervals. When the steel bar contacts the balls 45, the balls 45 reduce the friction between the steel bar and the moving rod 43, allowing the steel bar to be pulled out more smoothly.

[0041] In the process of continuous rotation and pulling out of the coiled steel bars, the coiled steel bars may become loose during rotation, and the coiled steel bars are easy to spread out. Therefore, a protective mechanism is set up to surround the coiled steel bars with a protective net 42 to prevent the coiled steel bars from spreading out and affecting the discharge. Since the steel bars from which the coiled steel bars are pulled out are located at the top, the vertical height of the coiled steel bars gradually becomes shorter during the process of continuous pulling out. When the pulled-out part of the steel bars contacts the moving rod 43, the moving rod 43 will be pressed downward, the extrusion spring 44 will be compressed, and the moving rod 43 will retract the protective net 42. When all the steel bars are pulled out, the extrusion spring 44 drives the moving rod 43 to move upward and reset.

[0042] like Figure 12 As shown, a guide mechanism is also included, which includes a support member 6 and a guide wheel 61. The support member 6 is connected to the upper left part of the support plate 11, and two guide wheels 61 are rotatably connected to the upper part of the support member 6. The steel bars pass through the two guide wheels 61 and are guided by the two guide wheels 61.

[0043] like Figure 12 As shown, cleaning cotton 62 is also included. The cleaning cotton 62 is attached to the guide wheel 61 through Velcro. The steel bars pass through the cleaning cotton 62, and impurities on the steel bars can be cleaned off through the cleaning cotton 62.

[0044] A method for forming an assembled steel truss floor deck comprises the following steps: S1: The electric push rod 17 controls the sliding frame 16 to move and drive the fixed frame 12 and the unloading frame 13 to rotate clockwise, and the unloading frame 13 rotates to a horizontal state.

[0045] S2: During the clockwise rotation of the unwinding frame 13, the movable frame 23 and the extrusion column 211 are driven by the connection rope 25, the winding seat 27 and other components to move, thereby bringing the limiting frame 2 together; S3: Use a trailer to push the coiled steel bars into the unwinding rack 13, and use the electric push rod 17 to control the sliding rack 16 to move and reset, so that the unwinding rack 13 rotates the coiled steel bars into a vertical state. During the counterclockwise rotation of the unwinding rack 13, the limiting rack 2 automatically resets the limit on the coiled steel bars; S4: Pull one end of the steel bar through between the guide wheels 61 and shape the steel bar through the forming machine 1.
