Description

Technical Field

[0001] This utility model relates to the field of widening equipment technology, and in particular to a large-tonnage bridge-type flat plate widening equipment. Background Technology

[0002] Large-tonnage bridge-type flatbed widening equipment is designed for the processing, transfer, and assembly of large workpieces such as heavy machinery components and bridge structural parts. It uses a bridge structure to stably support ultra-large and ultra-heavy workpieces and can be widened to adapt to workpieces of different sizes to meet the requirements of large tonnage load. However, the existing equipment has obvious shortcomings. First, it lacks flexibility and is difficult to adapt to rapid switching between multiple sites. Second, it has a limited range of adaptability and insufficient ability to adapt to a variety of workpieces. These two defects restrict its application. Utility Model Content

[0003] The main purpose of this utility model is to provide a large-tonnage bridge-type flat plate widening device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A large-tonnage bridge-type plate widening device includes a bridge-type bearing base, a main bearing plate fixedly connected to the upper end of the bridge-type bearing base, three positioning slots on the front and rear ends of the main bearing plate, two sliding limiting grooves with through upper ends on the upper left and upper right ends of the main bearing plate, two fastening bolts threadedly connected to the upper left and upper right ends of the main bearing plate, a connecting bracket block fixedly connected to the upper left and upper right ends of the main bearing plate, the connecting bracket block being located between the two fastening bolts, a workpiece limiting structure provided on the upper left and upper right ends of the main bearing plate, and an adjustable widening plate structure inserted into the front and rear ends of the main bearing plate. Preferably, the adjustable widening plate structure includes a widening extension frame, with three pins fixedly connected to one end of the widening extension frame near the main bearing plate, and sliding limit U-frames fixedly connected to the upper left and upper right parts of the widening extension frame, and a positioning frame fixedly connected to the rear right part of the widening extension frame, with a locking bolt threadedly connected to the middle right part of the positioning frame.

[0005] By adopting the above technical solutions: widening the extension frame to increase the bearing surface, using pins to enhance the connection stability with the main bearing plate, using a sliding limit U-frame to ensure smooth sliding, and using a positioning frame and locking bolts to fix the widened position, flexible widening is achieved, improving the equipment's adaptability and safety.

[0006] Preferably, the two adjustable widening plate structures are arranged in a front-to-back mirror image distribution, the inner left wall and inner right wall of the widening extension frame are tightly abutted against the left and right ends of the main bearing plate, respectively, and one end of the positioning frame extends into the widening extension frame and is tightly abutted against the end face of the main bearing plate.

[0007] By adopting the above technical solution: two adjustable widened plate structures are mirrored, the widened extension frame is tightly abutted against the main load-bearing plate, and the positioning frame abuts against the end face of the main load-bearing plate, ensuring balanced force, strengthening connection stability, preventing deviation during operation, and improving the load-bearing reliability of the equipment.

[0008] Preferably, the three pins correspond to the positions of the three positioning slots and their dimensions match.

[0009] By adopting the above technical solution, the pin and the positioning slot are aligned in position and matched in size, ensuring precise insertion between the two, enhancing the connection strength between the adjustable widened plate structure and the main load-bearing plate, avoiding shaking, and improving the stability of equipment operation.

[0010] Preferably, the sliding limit U-frame is slidably connected within the sliding limit groove, the length of the sliding limit U-frame is shorter than the length of the sliding limit groove, and the widened extension frame slides with the main bearing plate through the sliding limit U-frame and the sliding limit groove without separating from the main bearing plate.

[0011] By adopting the above technical solution, the sliding limit U-frame slides within the sliding limit groove and has a shorter length, ensuring that the widened extension frame slides smoothly and does not separate, achieving stable width adjustment, while preventing detachment, and improving operational safety and equipment durability.

[0012] Preferably, the workpiece limiting structure includes a limiting frame, with through bolt holes at both the upper front and upper rear ends of the limiting frame, and a protective insertion groove with through-holes at the front middle of the limiting frame, into which a reinforcing protective plate is inserted.

[0013] By adopting the above technical solution: the limiting frame restricts the position of the workpiece, the bolt holes cooperate with the fastening bolts to fix the frame, and the protective plug groove and reinforced protective plate enhance protection, effectively fixing the workpiece, preventing displacement, and improving the safety of operation.

[0014] Preferably, the lower middle part of the limiting frame is engaged with the connecting bracket block, and the limiting frame is detachably connected to the main bearing plate through two bolt holes and two fastening bolts.

[0015] By adopting the above technical solution, the limiting frame is snapped into the connecting bracket block, and is detachably connected to the main bearing plate through bolt holes and fastening bolts, which facilitates the installation and disassembly of the limiting structure, flexibly adapts to different workpieces, and improves the ease of use of the equipment.

[0016] Preferably, the two workpiece limiting structures are arranged in a left-right mirror image distribution.

[0017] By adopting the above technical solution, the two workpiece limiting structures are distributed in a mirror image on the left and right sides, which stably restricts the workpieces from both sides, ensures that the workpieces are placed in the center, and the force is evenly distributed, avoiding safety hazards caused by uneven loads and improving the load-bearing stability of the equipment.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the adjustable widening plate structure uses a sliding limit U-frame to slide within a sliding limit groove to achieve width adjustment. The pin and positioning slot are precisely matched to ensure a stable connection. The positioning frame and locking bolts can firmly fix the widening position. The front and rear mirror distribution structure makes the widening balanced. The widening extension frame is closely fitted with the main bearing plate to ensure stability and uniform force distribution during load bearing. At the same time, it avoids the separation of parts during adjustment, effectively improving the equipment's adaptability to workpieces of different widths and enhancing the safety and reliability during operation.

[0019] 2. In this utility model, the workpiece limiting structure includes a limiting frame that is snapped into a connecting card block and detachably connected to the main bearing plate via bolt holes and fastening bolts. This facilitates flexible loading, unloading, and adjustment according to the workpiece size. The reinforced protective plate is inserted into the protective plug-in slot, enhancing lateral protection for the workpiece. The left-right mirror-distributed structure provides stable limiting for the workpiece from both sides, preventing the workpiece from shifting during processing or transportation. This not only improves the stability of workpiece placement but also expands the equipment's adaptability to workpieces of different specifications, ensuring operational safety.
