[0002] In construction projects, columns and beams are subjected to greater stress, and concrete has high compressive strength but very low tensile strength. The steel cage can restrain the pile concrete so that it can withstand a certain axial tension. The existing steel cage welding device on the construction site includes two rotating wheels. When in use, the circular reinforcement is placed between the two rotating wheels, and then a longitudinal reinforcement is taken out and welded to the circular reinforcement in sequence according to a predetermined distance. After that, the longitudinal reinforcement is taken out in sequence, and the steel bars are rotated by the rotating wheel, so that the longitudinal reinforcement is welded to the circular reinforcement in sequence. However, when welding the longitudinal reinforcement, the existing steel cage welding and fixing device needs to fix the two ends of the longitudinal reinforcement one by one. After welding, the two ends of the longitudinal reinforcement need to be unfixed one by one, which wastes a lot of time in actual use, thereby affecting construction efficiency.

[0003] For example, the announcement number CN216780869U discloses a device for positioning longitudinal reinforcement stirrups for welding a steel cage. The device fixes one end of the longitudinal reinforcement by setting a number of limit rings, and the limit rings fix the longitudinal reinforcement by bolts. After welding is completed, the bolts on the limit rings need to be removed to release the fixation of one end of the steel cage, making it inconvenient to quickly remove the welded steel cage.

[0004] Based on this, a fixing device for welding a reinforcement cage is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

A fixing tube is fixed on the nut 19, and a first friction wheel 20 is fixed on the fixing tube. A switching mechanism for driving the fixing ring 16 to switch is provided inside the mounting base 13, and a driving mechanism is provided on the upper end of the mounting base 13 to facilitate the fixing plate 17 to clamp the longitudinal reinforcement. A push-and-turn mechanism is provided on the upper end of the mounting base 13 to facilitate the fixing plate 17 to quickly release the fixation of the steel cage. The switching mechanism facilitates the simultaneous rotation of the two mounting turntables 11 to switch the fixing ring 16, and the driving mechanism facilitates the rotation of the first friction wheel 20 so that the fixing plate 17 clamps the longitudinal reinforcement. The push-and-turn mechanism facilitates the fixing plate 17 to quickly release the fixation of the steel cage;

[0030] The switching mechanism includes two transmission shafts 21, and the two transmission shafts 21 are respectively arranged on one side of the two mounting turntables 11, and a first bevel gear and a second bevel gear are fixedly provided at both ends of the transmission shaft 21, and a third bevel gear and a fourth bevel gear are respectively meshed with the first bevel gear and the second bevel gear. The third bevel gear is fixed at one end of the fixed shaft, and the fourth bevel gear is fixed on the inner spline shaft, and the inner spline shaft is slidingly arranged on the outer spline shaft 22. The rotating shaft at one end of the outer spline shaft 22 is rotatably arranged in the mounting groove inside the mounting base 13, and a connecting shaft is fixed between the two outer spline shafts 22, and the rotating shaft at one end of one outer spline shaft 22 is fixedly connected to the output end of the first motor 23, and the first motor 23 is fixedly arranged on the mounting base 13. On one side, the inner spline shaft is rotatably arranged in the rotating groove on one side of the sliding seat 12, and one side of the sliding seat 12 is fixedly connected to the output ends of the two first electric push rods 15 respectively. The two first electric push rods 15 are fixedly arranged on the upper end of the mounting base 13. During use, when it is necessary to weld the steel cage, the longitudinal reinforcement is placed inside the two coaxially arranged fixing rings 16 respectively, and then the first friction wheel 20 is driven to rotate by the driving mechanism, and the first friction wheel 20 drives the fixing plate 17 to rotate. Under the action of the thread, the threaded rod 18 drives the fixing plate 17 to move, so that the longitudinal reinforcement is clamped and fixed, and then the first motor 23 is started, and the output end of the first motor 23 drives the two outer spline shafts 22 to rotate intermittently, so that the staff only needs to be in a fixed position to complete the loading.

[0031] The driving mechanism includes a second friction wheel 24, which is fixed on the output end of the second motor 25. The second motor 25 is fixed on a fixed frame, and the fixed frame is slidably arranged on the upper end of the mounting base 13. The second motor 25 is electrically connected to the controller 38, and the controller 38 is fixed on the fixed frame. The second friction wheel 24 is frictionally pressed against a first friction wheel 20. During use, when the mounting turntable 11 drives a fixed ring 16 to rotate to the position of the second motor 25, the first friction wheel 20 is frictionally pressed against the second friction wheel 24. Then the staff places one end of the longitudinal reinforcement inside the fixed ring 16. Then the staff controls the second motor 25 to start through the controller 38. The second motor 25 drives the second friction wheel 24 to rotate. The second friction wheel 24 drives the first friction wheel 20 to rotate. The first friction wheel 20 drives the threaded rod 18 to rotate through the fixed plate 17, thereby clamping and fixing the longitudinal reinforcement.

[0032] One side of the fixing frame is fixedly connected to the output end of the second electric push rod 26, and the second electric push rod 26 is fixedly arranged on the upper end of the mounting base 13. During use, when loading is completed, the output end of the second electric push rod 26 can pull the second motor 25 through the fixing frame to move the second friction wheel 24 away from the initial position, thereby preventing the second friction wheel 24 from rotating due to friction with the first friction wheel 20 during welding.

[0033] The pushing and turning mechanism includes a friction plate 28, and several of the first friction wheels 20 are frictionally matched with friction plates 28. One end of the friction plate 28 is slidably provided with a mounting box 29, and one end of the friction plate 28 is fixed with a fixed frame. A limit frame 32 is matched with the fixed frame, and the limit frame 32 is slidably arranged inside the mounting box 29. A return spring 33 is provided between one side of the limit frame 32 and the inside of the mounting box 29. A support rod is fixedly provided on one side of the mounting box 29, and the support rod is fixedly provided on the first mounting ring 30. The first mounting ring 30 is symmetrically provided with a sliding plate, and the sliding plate is slidably provided in the sliding groove at the upper end of the mounting base 13. One side of the sliding plate is fixedly connected to the output end of the third electric push rod 31, and the third electric push rod 31 is fixedly provided inside the mounting base 13. There is a reset spring 33 between one side of the friction plate 28 and the inside of the mounting box 29. When the tension spring 35 is in use, when the steel cage is welded and the steel cage needs to be released, the third electric push rod 31 is started, and the output end of the third electric push rod 31 pulls the first mounting ring 30 to move, so that the first mounting ring 30 drives several friction plates 28 to move. When the friction plates 28 are in close contact with the corresponding first friction wheels 20, the first friction wheels 20 rotate in the opposite direction, so that the fixing plate 17 is away from the steel cage, thereby releasing the fixation of the steel cage. At the same time, when one end of the limit frame 32 is in close contact with one side of the fixing ring 16 and continues to move, one end of the limit frame 32 is separated from the fixing frame, and under the action of the tension spring 35, the friction plate 28 is away from the first friction wheel 20. Then the output end of the third electric push rod 31 drives the first mounting ring 30 to return to the initial position. At this time, the release of the steel cage is completed, and the upper end of the mounting base 13 is provided with a reset mechanism for resetting the friction plates 28.

[0034] The reset mechanism includes a push rod 34 and a guide frame 36. A push rod 34 is fixed on one side of the friction plate 28. A guide frame 36 is provided at the upper end of the mounting base 13 and the initial position of the push rod 34. The working surface of the guide frame 36 is inclined. Several guide frames 36 are fixed on the second mounting ring 37. The second mounting ring 37 is fixed on the upper end of the mounting base 13. When in use, when the third electric push rod 31 drives the first mounting ring 30 to return to the initial position, the push rod 34 contacts the inclined surface of the guide frame 36, and the guide frame 36 guides the push rod 34, so that the push rod 34 pushes the friction plate 28 to move, so that the limit frame 32 fixes the friction plate 28 again.

[0035] One end of each push rod 34 is provided with a ball, which is convenient for reducing wear between the one end of the push rod 34 and the guide frame 36 during use.

[0036] A plurality of support seats 27 are slidingly provided in the guide groove at the upper end of the mounting base 13, which facilitates the placement of the steel sleeve when in use. At the same time, after welding is completed, the two first electric push rods 15 pull the mounting turntable 11 to move, so that the mounting turntable 11 is completely separated from the steel cage. At this time, the support seats 27 can support the steel cage, thereby facilitating the removal of the steel cage.

[0037] The above embodiment discloses a fixing device for welding a steel bar cage, wherein when the steel bar cage needs to be welded, the longitudinal bars are placed inside two coaxially arranged fixing rings 16 respectively, and the first friction wheel 20 and the second friction wheel 24 are rubbed tightly together. Then the staff places one end of the longitudinal bar inside the fixing ring 16, and then the staff controls the second motor 25 to start through the controller 38, and the second motor 25 drives the second friction wheel 24 to rotate, and the second friction wheel 24 drives the first friction wheel 20 to rotate, and the first friction wheel 20 drives the threaded rod 18 to rotate through the fixing plate 17, so that the longitudinal bar is clamped and fixed, and then the first motor 23 is started, and the output end of the first motor 23 drives the two external spline shafts 22 to rotate intermittently, so that the staff only needs to complete the loading at a fixed position, and then weld. When the steel cage is welded and the steel cage needs to be released, the third electric push rod 31 is started, and the third electric push rod When the first and second friction wheels 20 are in contact with each other, the first and second friction wheels 20 rotate in the opposite direction, causing the fixing plate 17 to move away from the steel cage, thereby releasing the fixation of the steel cage. At the same time, when one end of the limit frame 32 is in contact with one side of the fixing ring 16 and continues to move, one end of the limit frame 32 is separated from the fixing frame. Under the action of the tension spring 35, the friction plate 28 is separated from the first friction wheel 20. Then the output end of the third electric push rod 31 drives the first mounting ring 30 to return to the initial position. At this time, the fixation of the steel cage is completed. When the third electric push rod 31 drives the first mounting ring 30 to return to the initial position, the push rod 34 contacts the inclined surface of the guide frame 36. The guide frame 36 guides the push rod 34, causing the push rod 34 to push the friction plate 28 to move, so that the limit frame 32 fixes the friction plate 28 again.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
