Description

Technical Field

[0001] The utility model relates to the field of steel cage processing, in particular to a steel cage winding device. Background Art

[0002] In the production process of cast-in-place pile reinforcement cage, improving the degree of automation of reinforcement cage processing equipment can not only save a lot of labor costs, but also greatly improve production efficiency and ensure processing quality, thereby achieving the goal of improving economic benefits.

[0003] At present, there are many types of steel cage production equipment that have been interviewed and sold. Among them, there is a steel cage resistance welding and rolling welding machine based on the principle of resistance welding. It is widely praised for its fast production efficiency and stable production quality.

[0004] The center of the base of the existing steel cage production equipment is provided with a circular through hole, and the aperture determines the maximum diameter of the steel cage that can be processed. The guide plate is fixed in the through hole of the base and is concentric with the through hole. The number of guide holes and the aperture of the guide holes are determined according to actual needs, the radial position of each guide hole is determined according to the diameter of the steel cage to be produced, and the circumferential position of the guide holes is evenly distributed along the circumference. Electrode A is provided on the right side of the guide plate, and electrode A is in close contact with the main reinforcement. When the main reinforcement moves to the right, it slides and rubs with electrode A to ensure that the main reinforcement can obtain stable electricity from electrode A during the whole process of movement. A rotating plate is provided on the right side of the base, and the rotating plate is a circular ring-shaped component with an inner diameter larger than the outer diameter of the guide plate. The rotating plate is concentric with the through hole of the base and can perform continuous rotation relative to the base. Since electrode B and the stirrup guide frame are both fixed on the rotating plate, electrode B and the stirrup guide frame can also perform continuous circular motion relative to the base. The stirrups in the stirrup disc are transported to the electrode B through the stirrup guide frame. First, the end of the stirrup is welded and fixed to any main bar. Then, with the rightward movement of the guide disc and the circular movement of the rotating disc, the stirrups continuously sent from the stirrup disc through the stirrup guide frame are tightly wound on the main bar under the pressure of the electrode B. At the same time, since the main bar is connected to the first level of the power supply through the electrode A, the stirrups are connected to the other level of the same power supply through the electrode B. Therefore, at the moment when the stirrups are in close contact with the main bar, the two different electrodes form a short circuit through the close contact between the main bar and the stirrups. At this time, the strong current causes the contact part between the main bar and the stirrups to melt, and then fuse together to complete the welding of the stirrups and the main bar.

[0005] Defects of existing models:

[0006] The main reinforcement needs to pass through the guide hole to reach the traction disc, so manual loading is required, resulting in low production efficiency.

[0007] Due to the limitation of 12-meter length of raw materials, this machine can only produce steel cages with a length of less than 12 meters. However, in actual applications, there is often a need to produce steel cages with a length of more than 12 meters, and the main bars need to be overlapped and lengthened. Since the shape of the overlapped part of the main bars changes, the overlapped part cannot pass through the guide hole. Therefore, this machine has great limitations in actual applications.

[0008] In this machine, the electrode in contact with the main reinforcement is fixed on a complete ring and contacts the inner side of the reinforcement cage formed by multiple main reinforcements. When the traction disc drives the main reinforcement to move, there must be no obstacles on the inner side of the reinforcement cage formed by multiple main reinforcements, otherwise, it will interfere with the electrode ring. Therefore, this machine can only produce reinforcement cages that do not require reinforcement rings. If reinforcement rings are required, they can only be manually welded after the reinforcement cage is formed.

[0009] The moving mode of this machine is that the traction plate drags the steel cage to move. Therefore, when it is necessary to produce an extra-long steel cage, it requires a space at least twice the length of the steel cage, which is extremely inconvenient to use.

[0010] In order to solve the above-mentioned defects, there is an urgent need for a steel cage rolling welding device that can produce steel cages with internal reinforcement rings and can handle steel cage rolling welding devices with lap welds to meet market needs. Utility Model Content

[0011] According to the above technical problems, the utility model provides a reinforcing cage rebar winding device, which is characterized by being composed of a chassis rail, a lifting bracket, a mobile frame, a rebar winding wheel, a rotating electric ring, an electrode cover and a fixed chuck. The mobile frame is installed on the upper side of the chassis rail, and the rebar winding wheel, the rotating electric ring, the electrode cover and the fixed chuck are installed on the upper side of the mobile frame. The chassis rail is provided with a lifting frame rail, and the lifting bracket is installed on the upper side of the lifting frame rail;

[0012] The chassis rails are composed of a frame, a mobile rack, a lifting frame rail and a lifting frame rack. In order to facilitate transportation and lightweight assembly on the construction site, the chassis rails are designed in a modular manner. Except for the chassis connected to the fixed frame at the end, which does not require a lifting frame rail and a lifting frame rack, all other modules are equipped with lifting frame rails and lifting frame racks. When applied, the number of modules required can be determined according to the length of the steel cage produced.

[0013] The lifting bracket is composed of a support plate, a cross arm, a distance sensor, a hydraulic cylinder, a chassis, a slider and a traverse motor. During production, the slider fixed to the bottom of the chassis is placed on the lifting frame guide rail of the chassis guide rail. At this time, the gear on the rotating shaft of the traverse motor is meshed with the lifting frame rack.

[0014] The lifting frame can be driven to move horizontally by the rotation of the traverse motor. The extension and retraction of the hydraulic cylinder can drive the cross angle of the cross arm to change, thereby realizing the rise and fall of the bracket. The distance sensor can sense the distance between the lifting frame and the mobile frame. When the mobile frame moves a certain distance toward the lifting frame, the distance sensor sends a signal, and the lifting frame automatically descends to the lowest position to facilitate the passage of the mobile frame. In this solution, the origin position of the lifting frame is on the side of the chassis rail away from the fixed chuck, and the height is reduced to the lowest position.

[0015] The mobile rack is composed of a lateral motor, casters, a mobile frame, keel rollers, a ribbed wheel track, a ribbed wheel motor, a copper slider A, a compression spring, a connecting rod bracket, a copper slider B, a rotating electric ring track and a rotating electric ring motor. Among them, the rotating shaft of the lateral motor is equipped with a gear, which meshes with the rack of the mobile vehicle on the chassis track. When the motor rotates, the meshing of the gear and the rack can drive the mobile rack to move horizontally.

[0016] The steel cage frame roller is installed on the left side of the mobile frame. When the steel cage frame is lifted by the roller, the axis of the steel cage frame can be concentric with the axis of the fixed chuck. When the steel cage frame and the mobile frame move relative to each other, the roller can greatly reduce the friction.

[0017] A reinforcing wheel driving motor is installed at the center of the top left side of the mobile frame. The end of the motor's rotating shaft is equipped with a friction wheel, which can contact the edge of the reinforcing wheel. When the motor rotates, the reinforcing wheel is driven to rotate by friction. A reinforcing wheel rotating track is installed on the left inner side of the mobile frame. The center of the track is concentric with the steel cage frame, and the reinforcing wheel can rotate on the track in a controlled manner.

[0018] A set of connecting rod mechanisms is arranged on the right inner side of the mobile frame and just above each main reinforcement. The right end of the connecting rod is connected to the right inner side of the mobile frame through a rotating shaft and can swing slightly relative to the center direction of the circle of the side. A copper slider A is arranged on the top surface of the upper connecting rod. The copper slider A is composed of an insulating part and a conductive part. The insulating part is fixed to the top surface of the upper connecting rod by a compression spring. The conductive part is fixed on the insulating part and connected to the conductive part of the copper slider B through a wire. Since it is not in contact with the connecting rod, the connecting rod will not be charged when the conductive part is charged. The left end of the lower connecting rod is hinged with a copper slider B. When the steel cage skeleton and the mobile frame move relative to each other, the copper slider B can always slide on the main reinforcement corresponding to it, that is, it can always keep in contact with the corresponding main reinforcement. Similarly, the copper slider B is also composed of an insulating part and a conductive part. The conductive part does not contact the connecting rod. Therefore, when the conductive part is charged, the connecting rod will not be charged. Due to the characteristics of the connecting rod mechanism, even if the copper slider B swings slightly along with the connecting rod mechanism, its contact angle relative to the main rib will not change, that is, it can always maintain parallel contact with the main rib, thereby maximally ensuring that the contact area remains unchanged.

[0019] A rotating electric ring track is installed on the right inner side of the mobile frame. The center of the track is concentric with the steel cage frame, and the rotating electric ring can rotate in a controlled manner on the track.

[0020] A rotating electric ring driving motor is installed on the right side of the mobile frame. The gear at the end of the motor's rotating shaft can mesh with the annular rack of the rotating electric ring, and the rotating electric ring is driven to rotate by the rotation of the motor.

[0021] The rotating electric ring is composed of an insulating ring, an annular rack, a rib guide A, a rib electrode, a main rib electrode, a rib guide B, a rib power electrode, a main rib power electrode, a rotating ring and a pulley. Six pulleys are installed on the right side of the rotating ring. The six pulleys are clamped on the rotating electric ring track on the mobile frame. The rib guide A, the rib electrode and the rib guide B are installed on one side of the rotating ring. The rib electrode is connected to the connecting rod corresponding to the lower side of the rib guide B through a hinge shaft. A connecting rod is arranged on the outer side of the other side of the rotating ring. The left side of the connecting rod is fixed to the outer side of the rotating ring through a hinge shaft. The right side of the connecting rod is connected to the rib power electrode and the main rib power electrode through a hinge shaft; the rib guide A and the rib guide B are connected by a connecting rod;

[0022] The annular rack is installed on the inner side of the rotating ring, and an insulating ring is also provided on the inner side of the rotating ring. The insulating ring is divided into two layers. The insulating ring close to the inner side of the rotating ring is a complete closed loop structure, and the insulating ring far from the inner side of the rotating ring is a C-shaped opening structure, and the main rib electrode is inlaid at the opening. The insulating ring of the C-shaped opening structure and the main rib electrode together form a closed loop. The insulating ring is adjacent to the annular rack. When the rotating electric ring rotates, the main rib electrode will contact the conductive part of the copper slider A directly above each main rib in turn. Since the conductive part of the copper slider A is connected to the conductive part of the copper slider B, the conductive part of the copper slider B is always in contact with the main rib. Since the inner diameter of the insulating ring of the rotating electric ring is fixed, under the action of the compression spring at the upper connecting rod, the conductive part of the copper slider A and the main rib electrode, and the conductive part of the copper slider B and the main rib can maintain stable and close contact.

[0023] The structures of the main rib power electrode and the wound rib power electrode are exactly the same. Taking the main rib power electrode as an example, the conductive part and the insulating part are combined into one, the insulating part is fixed on the fixing part B, and the conductive part is connected to the conductive part of the main rib electrode through a wire. Similarly, the conductive part of the wound rib power electrode is also connected to the conductive part of the wound rib electrode. Fixing part B is fixed to the outer side of the rotating ring through the connecting rod and fixing part A. The compression spring can provide a supporting force to the connecting rod to ensure stable contact between the power electrode and the collector ring when the rotating ring rotates.

[0024] The insulating ring is a C-shaped opening structure, and the main rib electrode is embedded in the opening, that is, the insulating ring and the main rib electrode together form a closed loop. The closed loop is installed on the inner side of the rotating ring and is adjacent to the annular rack. Among them, the length of the main rib electrode determines the power-on time of the main rib, which can be adjusted according to the specific situation. When the rotating electric ring rotates, the main rib electrode will contact the conductive part of the copper slider A directly above each main rib in turn, that is, only one copper slider A among multiple sliders can obtain electricity. At the same time, since the conductive part of copper slider A is connected to the conductive part of copper slider B, the conductive part of copper slider B is always in contact with the main rib, so as the rotating electric ring rotates, power can be transmitted to the main rib in turn. At the same time, since the inner diameter of the insulating ring of the rotating electric ring is fixed, under the action of the compression spring at the upper connecting rod, the conductive part of copper slider A and the main rib electrode, and the conductive part of copper slider B and the main rib can maintain stable and close contact, thereby ensuring the stability of power transmission to the main rib.

[0025] The conductive part is fixed on the insulating part. Two guide rods are provided on the insulating part. After the compression spring is passed through the guide rod, it is inserted into the guide hole of the mounting plate. The conductive part can move up and down slightly relative to the mounting plate. The mounting plate is fixed on the structural component of the rotating ring, so when the rotating ring rotates, the rib-wound electrode will also rotate synchronously. Since the rotating ring has guide members A and B for the ribs, the ribs can always be directly below the rib-wound electrode under the action of the guide members, and receive the pressure from the compression spring at the guide rod so that the ribs can fit tightly on the main ribs when they intersect. At this moment, the rib-wound electrode and the main rib electrode can obtain electricity from the power-taking electrode at the same time. Therefore, the ribs and the main ribs are welded and fixed.

[0026] The electrode cover is composed of a winding collector ring, a main reinforcement collector ring, an insulating ring and an outer shell, wherein the outer shell is an annular structure, and two collector rings, a winding collector ring and a main reinforcement collector ring, are installed inside the outer shell directly above the winding reinforcement power taking electrode and the main reinforcement power taking electrode. The structures of the winding collector ring and the main reinforcement collector ring are the same, both of which are double-layer structures. The layer of the winding collector ring and the main reinforcement collector ring adjacent to the outer shell is a closed-loop insulating layer, and the layer away from the outer shell is a closed loop composed of collector rings and insulating blocks arranged alternately, and the number of collector rings is the same as the number of main reinforcements. The electrode cover is fixed on the right inner side of the mobile frame.

[0027] Inside the shell, directly above the winding tendon power taking electrode and the main tendon power taking electrode, there are two insulating rings arranged to ensure electrical insulation between the collector ring and the shell.

[0028] An insulating ring is installed inside the shell, and two collector rings are installed on the upper side of the insulating ring. One collector ring is composed of an insulating block and a ribbed collector ring. Multiple insulating blocks and ribbed collector rings are connected. When connected, the insulating block has ribbed collector rings on both sides, and the ribbed collector rings have insulating blocks on both sides. Another collector ring is composed of an insulating block and a main rib collector ring. Multiple insulating blocks and main rib collector rings are connected in sequence. When connected, the insulating block has main rib collector rings on both sides, and the main rib collector rings have insulating blocks on both sides. Insulating rings are installed on the other side of the two collector rings, and the electrode cover is fixed on the right inner side of the mobile frame. When the rotating electric ring rotates, the main rib and the ribbed power electrodes can obtain electricity of different polarities from the two collector rings at the same time.

[0029] The electrode cover is fixed on the right inner side of the moving frame.

[0030] The fixed chuck consists of a switchboard, a fixed base, a front extension sleeve pneumatic clamping jaws and a guide opening. The front extension sleeve is fixed on the base, and pneumatic clamping jaws and guide openings are installed on its inner side. The number of pneumatic clamping jaws and guide openings is the same as the number of main ribs, and they are evenly distributed along the circumference. The diameter of the circle formed by the center of each clamping jaw and guide opening is the same as the diameter of the circle formed by the center point of each main rib. The switchboard is installed in the base of the fixed chuck, eliminating the control cabinet.

[0031] When producing steel cages, the working order of the whole set of equipment is:

[0032] 1. When the transfer device delivers the steel cage frame to the top of the lifting frame, the lifting frame rises and lifts the steel cage frame to the concentric height of the fixed chuck. After the steel cage frame transfer device is evacuated, multiple lifting frames lift the steel cage frame and move toward the fixed chuck together, and send the end of the steel cage frame into the pneumatic claws of the fixed chuck and lock it. After that, multiple lifting frames are grouped in 1, 3, 5 / 2, 4, 6 to appropriately lower the height and detach from the steel cage frame, return to the original position, and rise to the lifting position again to complete the reset in sequence.

[0033] 2. Press the end of the rebar between the rebar electrode and any main rebar, manually start the welding key to weld the end of the rebar to the main rebar firmly, and then start the automatic welding. At this time, the mobile frame moves at a variable speed toward the tail end of the steel cage skeleton according to the rebar pitch required by the design. At the same time, the rotating electric ring starts to rotate at a certain speed. When the rebar crosses and contacts the main rebar, the main rebar and the rebar can obtain electricity of different polarities at the same time to complete the welding action. This action is carried out until all welding is completed.

[0034] 3. After the welding work is completed, the mobile frame continues to move forward until the frame is completely moved out of the steel cage position. After the transfer crane lifts the steel cage away from the work station, the lifting bracket automatically resets to the origin, the height drops to the lowest position, and the mobile frame automatically returns to the fixed frame position to start the next cycle.

[0035] The beneficial effects of the utility model are as follows: the utility model realizes the automatic production of the steel cage with reinforcing ring by changing the shape of the main reinforcement electrode and the power transmission mode. The utility model achieves the purpose of reducing the equipment footprint by changing the movement mode of the welding host.

[0036] The chassis guide rail, the lifting bracket and the mobile frame of the utility model cooperate with each other to realize the automatic feeding effect and improve the production efficiency.

[0037] The lifting bracket of the utility model is a detachable structure, and can be arbitrarily increased according to the length of the steel cage during use. It is suitable for producing steel cages of extra-long specifications. The lifting bracket can be added during production, thus avoiding the problem of the main shaft sagging due to excessive length.

[0038] The utility model can complete the reinforcement welding of the steel cage frame with the reinforcement ring by resistance welding, thereby improving the production efficiency. The utility model is a disassembly structure, occupies a small space, and is convenient for transportation and on-site assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] The present application is further described according to the accompanying drawings:

[0072] Example 1

[0073] The utility model proposes an innovative steel cage winding device, the design of which skillfully integrates multiple components such as chassis guide rails, lifting brackets, mobile racks, winding wheels, rotating electric rings, electrode covers and fixed chucks.

[0074] The chassis rail adopts modular design, which is convenient for transportation and on-site assembly. Its structure includes frame, mobile rack, lifting frame rail and lifting frame rack. According to the length of the steel cage, the required number of modules can be flexibly selected.

[0075] The lifting bracket is composed of a pallet, a cross arm, a distance sensor, a hydraulic cylinder, a chassis, a slider and a traverse motor. During the production process, the slider is placed on the lifting frame rail of the chassis rail, and the rotation of the traverse motor engages with the lifting frame rack to achieve lateral movement. The extension and retraction of the hydraulic cylinder changes the angle of the cross arm, thereby controlling the lifting and lowering of the bracket. The distance sensor monitors the distance between the lifting frame and the mobile rack to ensure that the mobile rack passes smoothly.

[0076] The mobile frame is composed of the lateral motor, casters, mobile frame, keel rollers, ribbed wheel track, ribbed wheel motor, copper slider A, compression spring, connecting rod bracket, copper slider B, rotating electric ring track and rotating electric ring motor. The gear of the lateral motor meshes with the rack of the mobile car on the chassis track to drive the mobile frame to move horizontally. A steel cage skeleton roller is installed on the left side of the mobile frame to reduce friction and ensure that the skeleton axis is concentric with the fixed chuck.

[0077] The reinforcing wheel drive motor is installed on the top left side of the mobile frame, and drives the reinforcing wheel to rotate through friction. The center of the reinforcing wheel track is concentric with the steel cage frame to ensure the controlled rotation of the reinforcing wheel.

[0078] A rotating electric ring driving motor is installed on the right side of the moving frame, and its gear is meshed with the annular rack of the rotating electric ring to realize the controlled rotation of the rotating electric ring.

[0079] The winding wheel is composed of a winding frame and a pulley. The pulley is installed on the side of the winding frame and drives the motor to rotate through the winding wheel. The rotating electric ring is composed of an insulating ring, an annular rack, a winding guide A, a winding electrode, a main rib electrode, a winding guide B, a winding power electrode, a main rib power electrode, a rotating ring and a pulley to ensure the stable rotation of the rotating electric ring.

[0080] The electrode cover is composed of a ribbed collector ring, a main rib collector ring, an insulating ring and a shell. The main rib or ribbed electrode is arranged inside the insulating ring. The electrode is connected to an external power supply through a wire. The electrode cover is fixed on the right inner side of the mobile frame.

[0081] The fixed chuck consists of a switchboard, a fixed base, a front extension sleeve, a pneumatic clamping claw and a guide mouth. The front extension sleeve is fixed on the base, and a pneumatic clamping claw and a guide mouth are installed on the inside to ensure the accurate grasping and fixing of the main reinforcement.

[0082] On the whole, the utility model provides an efficient and flexible steel cage winding device, which realizes the automation and efficiency of steel cage winding through modular design, precise sensor control and stable electrode contact, and greatly improves production efficiency and quality.

[0083] Working principle:

[0084] 1. Transportation and fixation of steel cage frame

[0085] When the steel cage frame transfer device delivers the steel cage to the top of the lifting frame, the lifting frame rises and lifts the steel cage frame to the concentric height of the fixed chuck. Subsequently, multiple lifting frames, in a specific grouping method, deliver the ends of the steel cage frame into the pneumatic claws of the fixed chuck and lock them. After completing this step, multiple lifting frames are reset in turn to prepare for the next step of reinforcement welding.

[0086] 2. Rebar welding process

[0087] The end of the winding wheel is crimped between the winding electrode and any main reinforcement. After the welding key is manually activated to weld the end of the winding reinforcement to the main reinforcement, the automatic welding process starts. At this time, the mobile frame moves at a variable speed toward the tail end of the steel cage skeleton according to the winding pitch required by the design. At the same time, the rotating electric ring starts to rotate, and when the winding reinforcement crosses the main reinforcement, the welding action is completed by electricity. This process is repeated until all welding is completed.

[0088] 3. Welding completion and equipment reset

[0089] After the welding work is completed, the mobile frame continues to move forward until the frame is completely moved out of the steel cage position. After the transfer crane lifts the welded steel cage away from the work station, the lifting bracket automatically resets to the origin, the height drops to the lowest position, and the mobile frame automatically returns to the fixed frame position to start the next cycle.

[0090] Example 2

[0091] The steel cage winding device proposed in this application has a structure that cleverly integrates multiple core components such as chassis guide rails, lifting brackets, mobile racks, winding wheels, rotating electric rings, electrode covers and fixed chucks.

[0092] The chassis rail of the device is composed of a frame, a mobile rack, a lifting frame rail and a lifting frame rack. In order to facilitate transportation and lightweight on-site assembly, the chassis rail adopts a modular design, and the required number of modules can be flexibly selected according to the length of the steel cage produced.

[0093] The lifting bracket is composed of a pallet, a cross arm, a distance sensor, a hydraulic cylinder, a chassis, a slider, and a transverse motor. During the production process, the slider fixed to the bottom of the chassis is placed on the lifting frame guide rail of the chassis guide rail, and the rotation of the transverse motor engages with the lifting frame rack to achieve lateral movement. The extension and retraction of the hydraulic cylinder drives the cross angle of the cross arm to change, thereby achieving the rise and fall of the bracket. The distance sensor can sense the distance between the lifting frame and the mobile rack to ensure that the mobile rack passes smoothly.

[0094] The mobile frame is composed of a traverse motor, casters, a mobile frame, keel rollers, a ribbed wheel track, a ribbed wheel motor, a copper slider A, a compression spring, a connecting rod bracket, a copper slider B, a rotating electric ring track and a rotating electric ring motor. The rotating shaft of the traverse motor is equipped with a gear, which meshes with the rack of the mobile vehicle on the chassis track to drive the mobile frame to move horizontally. A steel cage skeleton roller is installed on the left side of the mobile frame to reduce friction and ensure that the skeleton axis is concentric with the fixed chuck.

[0095] The reinforcing wheel drive motor is installed on the top left side of the mobile frame, and drives the reinforcing wheel to rotate through friction. The center of the reinforcing wheel track is concentric with the steel cage frame to ensure the controlled rotation of the reinforcing wheel.

[0096] A set of connecting rod mechanisms is arranged on the right inner side of the mobile frame and just above each main reinforcement. The right end of the connecting rod is connected to the right inner side of the mobile frame through a rotating shaft and can swing slightly relative to the center direction of the circle of the side. A copper slider A is arranged on the top surface of the upper connecting rod. The copper slider A is composed of an insulating part and a conductive part. The insulating part is fixed to the top surface of the upper connecting rod by a compression spring. The conductive part is fixed on the insulating part and connected to the conductive part of the copper slider B through a wire. Since it is not in contact with the connecting rod, the connecting rod will not be charged when the conductive part is charged. The left end of the lower connecting rod is hinged with a copper slider B. When the steel cage skeleton and the mobile frame move relative to each other, the copper slider B can always slide on the main reinforcement corresponding to it, that is, it can always keep in contact with the corresponding main reinforcement. Similarly, the copper slider B is also composed of an insulating part and a conductive part. The conductive part does not contact the connecting rod. Therefore, when the conductive part is charged, the connecting rod will not be charged. Due to the characteristics of the connecting rod mechanism, even if the copper slider B swings slightly along with the connecting rod mechanism, its contact angle relative to the main rib will not change, that is, it can always maintain parallel contact with the main rib, thereby maximally ensuring that the contact area remains unchanged.

[0097] A rotating electric ring track is installed on the right inner side of the mobile frame. The center of the track is concentric with the steel cage frame, and the rotating electric ring can rotate in a controlled manner on the track.

[0098] A rotating electric ring driving motor is installed on the right side of the mobile frame. The gear at the end of the motor's rotating shaft can mesh with the annular rack of the rotating electric ring, and the rotating electric ring is driven to rotate by the rotation of the motor.

[0099] The rib winding wheel is composed of a rib winding frame and a pulley. The pulley is installed on the side of the rib winding frame, and 6 pulleys are clamped on the outside of the rib winding wheel track. Therefore, when the rib winding wheel driving motor rotates, the rib winding wheel can be controlled to rotate.

[0100] The rotating electric ring is composed of an insulating ring, an annular rack, a rib guide A, a rib electrode, a main rib electrode, a rib guide B, a rib power electrode, a main rib power electrode, a rotating ring and a pulley. Six pulleys are installed on the right side of the rotating ring. The six pulleys are clamped on the rotating electric ring track on the mobile frame. The rib guide A, the rib electrode and the rib guide B are installed on one side of the rotating ring. The rib electrode is connected to the connecting rod corresponding to the lower side of the rib guide B through a hinge shaft. A connecting rod is arranged on the outer side of the other side of the rotating ring. The left side of the connecting rod is fixed to the outer side of the rotating ring through a hinge shaft. The right side of the connecting rod is connected to the rib power electrode and the main rib power electrode through a hinge shaft; the rib guide A and the rib guide B are connected by a connecting rod;

[0101] The annular rack is installed on the inner side of the rotating ring, and an insulating ring is also provided on the inner side of the rotating ring. The insulating ring is divided into two layers. The insulating ring close to the inner side of the rotating ring is a complete closed loop structure, and the insulating ring far from the inner side of the rotating ring is a C-shaped opening structure, and the main rib electrode is inlaid at the opening. The insulating ring of the C-shaped opening structure and the main rib electrode together form a closed loop. The insulating ring is adjacent to the annular rack. When the rotating electric ring rotates, the main rib electrode will contact the conductive part of the copper slider A directly above each main rib in turn. Since the conductive part of the copper slider A is connected to the conductive part of the copper slider B, the conductive part of the copper slider B is always in contact with the main rib. Since the inner diameter of the insulating ring of the rotating electric ring is fixed, under the action of the compression spring at the upper connecting rod, the conductive part of the copper slider A and the main rib electrode, and the conductive part of the copper slider B and the main rib can maintain stable and close contact.

[0102] The electrode cover is composed of a winding collector ring, a main reinforcement collector ring, an insulating ring and an outer shell, wherein the outer shell is an annular structure, and two collector rings, a winding collector ring and a main reinforcement collector ring, are installed inside the outer shell directly above the winding reinforcement power taking electrode and the main reinforcement power taking electrode. The structures of the winding collector ring and the main reinforcement collector ring are the same, both of which are double-layer structures. The layer of the winding collector ring and the main reinforcement collector ring adjacent to the outer shell is a closed-loop insulating layer, and the layer away from the outer shell is a closed loop composed of collector rings and insulating blocks arranged alternately, and the number of collector rings is the same as the number of main reinforcements. The electrode cover is fixed on the right inner side of the mobile frame.

[0103] The inside of the shell is located directly above the winding reinforcement power electrode and the main reinforcement power electrode, and the two insulating rings configured can ensure the electrical insulation between the collector ring and the shell.

[0104] An insulating ring is installed inside the shell, and two collector rings are installed on the upper side of the insulating ring. One collector ring is composed of an insulating block and a ribbed collector ring. Multiple insulating blocks and ribbed collector rings are connected. When connected, the insulating block has ribbed collector rings on both sides, and the ribbed collector rings have insulating blocks on both sides. Another collector ring is composed of an insulating block and a main rib collector ring. Multiple insulating blocks and main rib collector rings are connected in sequence. When connected, the insulating block has main rib collector rings on both sides, and the main rib collector rings have insulating blocks on both sides. Insulating rings are installed on the other side of the two collector rings, and the electrode cover is fixed on the right inner side of the mobile frame. When the rotating electric ring rotates, the main rib and the ribbed power electrodes can obtain electricity of different polarities from the two collector rings at the same time.

[0105] The electrode cover is fixed on the right inner side of the moving frame.

[0106] The fixed chuck consists of a switchboard, a fixed base, a front extension sleeve pneumatic clamping jaws and a guide opening. The front extension sleeve is fixed on the base, and pneumatic clamping jaws and guide openings are installed on its inner side. The number of pneumatic clamping jaws and guide openings is the same as the number of main ribs, and they are evenly distributed along the circumference. The diameter of the circle formed by the center of each clamping jaw and guide opening is the same as the diameter of the circle formed by the center point of each main rib. The switchboard is installed in the base of the fixed chuck, eliminating the control cabinet.

[0107] Example 3

[0108] The manufacturing of steel cages is usually divided into two main steps: first, forming the skeleton of the steel cage, and second, completing the rebar winding process. Nowadays, these two steps can be completed at the same station, significantly reducing production efficiency.

[0109] The present application proposes a solution that is connected to a steel cage frame forming device to achieve continuous operation. The present application receives the steel cage frame from the forming device and lifts the frame to an appropriate height when the lifting frame delivers the steel cage to just above the fixed chuck. The lifting frame then introduces the end of the steel cage into the pneumatic claws of the fixed chuck and ensures a secure clamping. Multiple lifting frames are reset in sequence to prepare for the reinforcing bar welding step.

[0110] After the steel cage skeleton enters the fixed chuck, the end of the winding wheel is crimped between the winding electrode and a main bar. The staff manually activates the welding key to weld the end of the winding bar to the main bar, and then the automatic welding process starts. At this time, the mobile frame moves at a variable speed toward the tail end of the steel cage skeleton according to the preset winding pitch. At the same time, the rotating electric ring starts to rotate, and when the winding bar crosses the main bar, the welding action is completed by electricity. This process is repeated until all welding is completed.

[0111] After welding is completed, the mobile frame continues to move forward until it is completely moved out of the steel cage position. The welded steel cage is then lifted away from the workstation by the transfer crane. The lifting bracket automatically resets to the origin and drops to the lowest position, and the mobile frame automatically returns to the fixed frame position to prepare for the next steel cage frame winding operation.

[0112] In this way, the present application provides a solution for improving the production efficiency of steel cages, which not only optimizes the production process, but also reduces manual operations and improves the overall automation level of the operation.
