Description

Technical Field

[0001] This utility model relates to the field of pipe piles, and more particularly to the field of roll welding, specifically referring to a tail device of a roll welding machine for achieving precise control of the roll welding accuracy of reinforcing bars. Background Technology

[0002] Currently, the tail traction trolley of the roll welding machine uses a variable frequency electric drive chain to move the trolley linearly. The variable frequency motor has poor control precision, and the chain, limited by tension and its own precision, has low transmission accuracy. During the traction of the reinforcing cage, it needs to be lifted. Because there are many types of pipe piles produced, the current scissor fork lifting height needs to be manually adjusted to accommodate multiple specifications, which is very inconvenient. At the same time, the transmission friction between the reinforcing cage and the scissor fork is high. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tail device for a welding machine that achieves precise control of the welding accuracy of cage reinforcement, which is energy-saving, has low friction, and is widely applicable.

[0004] To achieve the above objectives, the tail end device of the welding machine for precisely controlling the welding accuracy of the reinforcing bars according to this utility model is as follows:

[0005] The tail end device of this welding machine for achieving precise control of the welding accuracy of reinforcing bars is characterized by the following features: the device includes a tail frame, a traction trolley, a lifting scissor fork, and a swing arm unloading assembly. The tail frame includes a base and two linear guide rails, which are fixed to the base and are parallel to each other. The traction trolley is mounted on the two linear guide rails and supports forward and backward movement on them. The lifting scissor fork is mounted in the tail frame and located between the two linear guide rails, supporting vertical lifting. The swing arm unloading assembly is mounted on the tail frame, and its swing arm supports upward rotation.

[0006] Preferably, the lifting scissor fork includes a driven link, a driving link, an upper support plate, an electric push rod, and a cylinder. The electric push rod and the cylinder are both mounted on the base frame. The front end of the electric push rod is connected to the rear end of the cylinder. The middle end of the driven link and the middle end of the driving link are connected through an intermediate hinge point. The top end of the driving link is connected to one end of the upper support plate. The top end of the driven link is connected to the other end of the upper support plate through a limiting hinge point. The bottom end of the driven link is connected to the base frame. The bottom end of the driving link is connected to a translation hinge point. The translation hinge point is mounted on the electric push rod and connected to the cylinder.

[0007] Preferably, the lifting scissor fork further includes a blocking block connected to an electric push rod, and the translation hinge is installed between the cylinder and the blocking block.

[0008] Preferably, the lifting scissor fork further includes a chain that wraps around two gears on the upper support plate and rotates around the gears, with the upper part of the chain contacting the outer edge of the rib cage.

[0009] Preferably, the lifting scissor fork further includes a fork structure, which is mounted on the upper support plate and supports extending into and holding the rib cage.

[0010] Preferably, the swing arm unloading assembly includes a swing arm cylinder, a swing arm, and a rotating shaft. One end of the swing arm is connected to the tailstock via the rotating shaft, and the other end of the swing arm supports rotation around the rotating shaft. The bottom end of the swing arm cylinder is fixed to the base frame of the tailstock, and the top end of the swing arm cylinder is connected to the swing arm via a hinge point. The extension of the swing arm cylinder causes the swing arm to rotate upward around the rotating shaft.

[0011] Preferably, a rib cage is placed on the tail frame, and the rib cage is placed between the two linear guide rails. The traction disc in front of the traction trolley is connected to the rib cage and drags the rib cage to move. When the rib cage is above the lifting scissor fork, the lifting scissor fork lifts the rib cage up and down. When the rib cage is above the swing arm unloading assembly, the swing arm unloading assembly rotates and pushes the rib cage off the tail frame.

[0012] Preferably, the center of the traction disc in front of the traction trolley and the center of the reinforcing cage are at the same height.

[0013] The tail device of the roller welding machine that adopts this utility model to achieve precise control of the welding accuracy of the reinforcing cage is an upgrade from the old tail device. The lifting scissor fork and the precision traction trolley are upgraded to protect the entire upgraded tail device of the roller welding machine. The precision traction trolley reliably controls the traction speed and position, matches the welding speed of the spiral reinforcement of the roller welding machine, ensures the spacing of each revolution, facilitates the automatic control of the lifting height of the reinforcement cage by the lifting scissor fork, is compatible with various pipe pile specifications, and facilitates the reduction of traction friction by the linear slide rail, thus saving energy.

[0041] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.

[0042] This utility model discloses a tail assembly for a welding machine that enables precise control of the welding accuracy of reinforcing bars. The assembly includes a tail frame 1, a traction trolley 2, a lifting scissor fork 3, and a swing arm unloading assembly 4. The tail frame 1 includes a base and two linear guide rails. The two linear guide rails are fixed to the base frame and are parallel to each other. The traction trolley 2 is mounted on the two linear guide rails and supports forward and backward movement on them. The lifting scissor fork 3 is mounted in the tail frame 1 and located between the two linear guide rails, supporting vertical lifting. The swing arm unloading assembly 4 is mounted on the tail frame 1, and its swing arm 6 supports upward rotation.

[0043] In a preferred embodiment of this utility model, the lifting scissor fork 3 includes a driven link 11, a driving link 12, an upper support plate 13, an electric push rod 14, and a cylinder 15. The electric push rod 14 and the cylinder 15 are both mounted on the base frame. The front end of the electric push rod 14 is connected to the rear end of the cylinder 15. The middle end of the driven link 11 and the middle end of the driving link 12 are connected through an intermediate hinge point. The top end of the driving link 12 is connected to one end of the upper support plate 13. The top end of the driven link 11 is connected to the other end of the upper support plate 13 through a limiting hinge point. The bottom end of the driven link 11 is connected to the base frame. The bottom end of the driving link 12 is connected to a translation hinge point. The translation hinge point is mounted on the electric push rod 14 and connected to the cylinder 15.

[0044] In a preferred embodiment of the present invention, the lifting scissor fork 3 further includes a blocking block, which is connected to the electric push rod 14, and the translation hinge point is installed between the cylinder 15 and the blocking block.

[0045] In a preferred embodiment of the present invention, the lifting scissor fork 3 further includes a chain, which is wrapped around two gears on the upper support plate 13 and rotates around the gears. The upper part of the chain contacts the outer edge of the rib cage.

[0046] In a preferred embodiment of the present invention, the lifting scissor fork 3 further includes a fork structure, which is mounted on the upper support plate 13 and supports extending into the rib cage and holding the rib cage in place.

[0047] In a preferred embodiment of the present invention, the swing arm unloading assembly 4 includes a swing arm cylinder 5, a swing arm 6, and a rotating shaft 7. One end of the swing arm 6 is connected to the tailstock 1 via the rotating shaft 7, and the other end of the swing arm 6 supports rotation around the rotating shaft 7. The bottom end of the swing arm cylinder 5 is fixed to the base frame of the tailstock 1, and the top end of the swing arm cylinder 5 is connected to the swing arm 6 via a hinge point. The extension of the swing arm cylinder 5 causes the swing arm 6 to rotate upward around the rotating shaft 7.

[0048] In a preferred embodiment of this utility model, a rib cage is placed on the tail frame 1, and the rib cage is placed between the two linear guide rails. The traction disc in front of the traction trolley 2 is connected to the rib cage and drags the rib cage to move. When the rib cage is above the lifting scissor fork 3, the lifting scissor fork 3 lifts the rib cage up and down. When the rib cage is above the swing arm unloading assembly 4, the swing arm unloading assembly 4 rotates and pushes the rib cage off the tail frame 1.

[0049] In a preferred embodiment of this utility model, the center of the traction disc in front of the traction trolley 2 and the center of the reinforcing cage are at the same height.

[0050] In a specific embodiment of this invention, the accuracy of the moving position of the dragging rib cage is controlled. Used in conjunction with a roll welding machine, it ensures the pitch of each turn of the roll-welded spiral rib. Multiple sets of scissor forks lift and hold the rib cage in the same position, with an automatic adjustment function. When pulling the rib cage, the friction between the parts in contact with the lifting mechanism (chain and sprocket structure) is minimal.

[0051] This device includes a traction trolley 2 and a lifting scissor fork 3, which is also a linear guide rod.

[0052] The cylinder extends, the translation hinge point moves forward, and the driving linkage swings inward, causing the upper support plate to move upward. When the translation hinge point hits the stop block and stops, the upper support plate also stops rising. The stop block is connected to the electric push rod. When the electric push rod moves inward a certain distance, the distance the cylinder extends becomes shorter, thereby adjusting the lifting height of the upper support plate.

[0053] The center height of the reinforcing cage remains constant. For reinforcing cages with different outer diameters, the height of the upper support plate needs to be adjusted so that the outer edge of the chain-supported reinforcing cage contacts the upper support plate, thereby supporting the reinforcing cage from the surface and preventing it from sagging.

[0054] The operation process of the swing arm unloading assembly 4: When the cylinder 5 extends, the swing arm 6 swings around the rotating shaft 7 outward from the equipment, thereby pushing the rib cage above the swing arm 6 out of the equipment.

[0055] The entire production cycle at the tail end: The traction trolley 2 moves forward into the roll welding machine, the traction disc engages the upsetting head of the rib cage, and moves backward according to the required roll welding speed. When it passes one of the lifting scissor forks 3, the cylinder 5 inside the lifting scissor fork 3 extends, and the electric push rod is limited to support the rib cage. Until the roll welding is completed, the traction disc releases the head of the rib cage and moves backward a short distance. The swing arm 6 pushes the rib cage out of the equipment, the lifting scissor fork 3 rises and falls back to its original position, and the swing arm 6 and cylinder 5 retract to their original positions.
