Description

Technical Field

[0001] This utility model relates to the technical field of equipment for processing steel cages for tunnel segments, and in particular to a high-precision forming device for steel cages for tunnel segments. Background Technology

[0002] In the process of urban infrastructure construction, the scale of underground engineering projects such as subways and tunnels continues to expand. As the core component for constructing these underground spaces, the importance of segment rebar cages is self-evident. Currently, high-precision forming devices for segment rebar cages have become the focus of industry attention. These devices, with the help of advanced automation technology and precise mechanical structures, can efficiently complete a series of processes such as main bar positioning, stirrup binding, and overall forming. In practical applications, they have significantly improved the production efficiency of rebar cages, accurately controlled the size and position of each component, and provided a solid guarantee for creating high-quality and highly stable segment rebar cages, powerfully promoting underground engineering construction to a new level.

[0003] A search revealed Chinese Patent Publication No. CN206868989U, which discloses a rapid and high-precision forming device for tunnel segment reinforcement cages. This device, belonging to the category of tunnel segment reinforcement cage processing equipment, includes an arc-shaped slide platform, an active thrust arm, a roller frame assembly for clamping transverse arc rib components, a stirrup assembly feeding rack, and guide rails, all sequentially arranged on the slide platform. Welding mechanisms are located on both sides of the slide platform. The roller frame assembly includes a roller frame with multiple rows of rollers mounted side-by-side. Each roller has a limiting component for restricting the transverse arc rib components. A clamping roller lifting frame is located in the middle of the roller frame, with multiple clamping rollers mounted side-by-side. The rollers and clamping rollers are arranged alternately. This invention achieves the purpose of automatically feeding the disassembled and assembled stirrup and transverse arc rib components and realizing rapid automatic welding. However, in actual use, since the required sizes of the tunnel segment reinforcement cages vary, different sized forming devices need to be customized, thus increasing costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-precision forming device for segmented steel cages, which aims to improve the problem that existing technologies cannot process segmented steel cages of different sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision forming device for steel cages of tubular segments, comprising a movable base plate and a fixed base plate. A DC motor is fixedly connected to the left side of the outer wall of the movable base plate. The output end of the DC motor passes through the movable base plate and is fixedly connected to a rotating column. A limiting turntable is fixedly connected to the left side of the outer wall of the rotating column. Multiple sliding blocks are slidably connected to the inner wall of the limiting turntable. A conical positioning block is fixedly connected to the right side of the sliding block. An auxiliary cylinder is fixedly connected to the middle of the outer wall of the limiting turntable. Multiple hollow plates are fixedly connected to the outer wall of the auxiliary cylinder. A slider is slidably connected to the inner wall of the hollow plate. A fastening screw is threaded to the right side of the hollow plate. An arc-shaped support plate is fixedly connected to the outer side of the slider. A limiting hole plate is slidably connected to the right side of the outer wall of the limiting turntable. A clamping assembly is provided on the outer wall of the sliding block. A welding mechanism is provided on the top of the movable base plate.

[0006] The above technical solution involves the following steps: Before using the device, adjust the position of the slider in the hollow plate according to the required welding size of the rebar cage. Then, by rotating the fastening screws, the adjusted slider position in the hollow plate is completed. Next, the segments to be welded are sequentially inserted from the front of the device, with the left side of the segment inserted into the conical positioning block. Then, using the clamping assembly, the sliding handle is rotated, causing the threaded column to rotate. As the threaded column rotates, the sliding clamp moves, thus clamping and fixing the left side of the segment. Then, the DC motor is slowly started, causing the rotating column to rotate. This process of fixing the segments is repeated until all required segments are fixed, thus enabling the clamping and fixing of the rebar cage according to the required welding size.

[0007] As a further description of the above technical solution:

A laser welding gun is fixedly connected to the top of the inner wall of the support column. A servo motor is fixedly connected to the rear top of the sliding plate. A gear is fixedly connected to the output end of the servo motor. A rack is fixedly connected to the rear top of the movable base plate. The rack meshes with the gear. An extrusion block is fixedly connected to the rear side of the support column.

[0009] Through the above technical solution: when all the required segments are fixed and installed, the laser welding gun is started, and the steel bars to be fixed are pressed and attached to the outside of the segments by the extrusion block. As the DC motor rotates and the laser welding gun welds, the steel bars are welded around the outside of the segments. At the same time, the servo motor is started to rotate at a constant speed, so that the gears rotate. Under the meshing action of the gears and racks, the sliding plate moves to the right on the upper side of the slide rail, so that the welded steel bars are welded and wrapped around the outside of the segments in a spiral state, thereby completing the welding and fixing of the steel cage.

[0010] As a further description of the above technical solution:

[0011] The clamping assembly includes multiple fixing bars, which are respectively fixedly connected to the outer wall of the sliding block. A sliding clamp is slidably connected to the right side of each fixing bar, and a threaded post is rotatably connected to the outer side of each fixing bar. The outer wall of the threaded post is threadedly connected to the sliding clamp, and a sliding handle is slidably connected to the other end of the threaded post.

[0012] The above technical solution allows the sliding clamp to move by rotating the threaded column, thereby clamping the pipe segment to be welded, while the sliding throttle rotates the threaded column more effectively.

Limiting rods are fixedly connected to the front and rear sides of the left side of the fixed base plate. The outer walls of the limiting rods are slidably connected to the movable base plate.

[0018] The above technical solution allows the movable base plate to be moved to the left by a hydraulic rod, and the direction of movement of the movable base plate can be restricted by a limiting rod.

[0019] As a further description of the above technical solution:

[0020] A warning sign block is fixedly connected to the front right side of the outer wall of the limiting hole plate, and a nameplate is fixedly connected to the bottom right side of the outer wall of the limiting hole plate.

[0021] The above technical solution allows operators to be reminded of precautions during use through warning signs, and nameplates to easily record the basic model and manufacturing date of the equipment.

[0022] As a further description of the above technical solution:

[0023] A limiting hollow block is fixedly connected to the top right side of the fixed base plate, and multiple auxiliary wheels are rotatably connected to the inner wall of the limiting hollow block.

[0024] The above technical solution allows the limiting hole plate to be restricted by the limiting hollow block, and the auxiliary wheel facilitates the rotation of the limiting hole plate inside the limiting hollow block.

Rotating the threaded column 16 can move the sliding clamping plate 15, thereby clamping the pipe segment to be welded. The sliding handle 17 can better rotate the threaded column 16.

[0041] Specifically, before using the device, adjust the position of the slider 10 in the hollow plate 9 according to the required welding size of the rebar cage, and complete the adjustment of the slider 10 in the hollow plate 9 by rotating the fastening screw 11. Then, insert the pipe segments to be welded one by one from the front of the device, and insert the left side of the pipe segment into the conical positioning block 7.

[0048] Working principle: Before using the device, firstly, adjust the position of the slider 10 in the hollow plate 9 according to the required welding size of the rebar cage. By rotating the fastening screw 11, ensure the adjusted slider 10 is fixed in the hollow plate 9. Next, insert the pipe segments to be welded sequentially from the front of the device, and insert the left side of the pipe segment into the conical positioning block 7. Then, using the clamping assembly, rotate the sliding handle 17 to drive the threaded column 16 to rotate. As the threaded column 16 rotates, the sliding clamp 15 moves accordingly, thereby clamping and fixing the left side of the pipe segment. Afterward, start the DC motor 4 to make the rotating column 5 start rotating. Repeat the above method of fixing the pipe segments to ensure that all the pipe segments to be welded are fixed. This allows for... The steel cage is clamped and fixed according to the required welding size. After all the necessary segments have been fixed and installed, the laser welding gun 204 is started. Through the action of the extrusion block 208, the steel bars to be fixed are extruded and attached to the outside of the segment. As the DC motor 4 rotates and under the welding action of the laser welding gun 204, the steel bars will be wrapped around and welded to the outside of the segment. At the same time, the servo motor 206 will be started to rotate at a constant speed, driving the gear 207 to rotate. Under the meshing effect of the gear 207 and the rack 205, the sliding plate 202 will move to the right on the slide rail 201. This process makes the welded steel bars spirally wrapped around and fixed to the outside of the segment, thereby realizing the welding and fixing of the steel cage.
