Description

Technical Field

[0001] This utility model relates to the field of cantilever arms, and more particularly to the field of cantilever arm components with adjustable ends, specifically referring to a cantilever arm component device with adjustable ends. Background Technology

[0002] The cantilever traction assembly currently in production uses an integral structure. In actual production, due to the inherent defects of the cantilever structure, the center of gravity of this assembly is far from the mounting flange, causing it to sag naturally. After a period of use, the vibration of the welding equipment causes the locking plate connected to the cantilever assembly to sag at an angle. As a result, after the main cage reinforcement is welded, the flatness of the end face of the main cage reinforcement has an inclination error that exceeds the specified value. This error will gradually increase over time, affecting the quality of the subsequent end plate installation process. In addition, there are many specifications of cage reinforcement produced. When changing production models, the front locking plate needs to be replaced. After replacing the locking plate, the flatness of the end face of the locking plate also needs to be readjusted. The current method involves manually readjusting the entire cantilever assembly after a period of use on the production floor or when changing production models and replacing the locking disc. This ensures the flatness of the locking disc's end face, guaranteeing that the produced cage reinforcement meets the quality and process requirements. However, the existing integrated structure makes manual fine-tuning difficult. Adjustments are only made by adding shims at the bolts connecting the rear flange to the traction trolley. Adjusting at this point results in excessive changes in the front locking disc's orientation, making adjustments difficult and time-consuming. Furthermore, adjustments can only be made at the rear, which means workers are too far from the locking disc to observe and measure whether the adjusted locking disc meets the requirements. Two operators are needed for better adjustments, leading to slow adjustment efficiency, high manpower requirements, and reduced production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a two-end adjustable cantilever assembly device that is easy to operate, quick to adjust, and has a wide range of applications.

[0004] To achieve the above objectives, the adjustable cantilever assembly device at both ends of this utility model is as follows:

[0005] The main features of this adjustable cantilever assembly are that the assembly includes a traction trolley, a long cantilever, a cantilever flange, a locking disc, and an adjusting screw. The long cantilever is connected to the traction trolley and includes a large flange face and a cantilever arm. One end of the cantilever arm is mounted on the large flange face and is located at the center of the large flange face. The cantilever flange is mounted on the other end of the cantilever arm and is also connected to the locking disc. The adjusting screw is mounted on the traction trolley and rests against the long cantilever arm from below.

[0006] Preferably, the device further includes a plurality of end-face adjusting bolts, which are mounted on the large flange face of the long cantilever, and the tightening depth of the end-face adjusting bolts on the long cantilever supports adjustment.

[0007] Preferably, the device further includes a quick-adjusting bolt, which is screwed into a threaded hole in the long cantilever flange, with the end of the quick-adjusting bolt abutting against the cantilever flange, and the tightening depth of the quick-adjusting bolt on the cantilever flange supporting adjustment.

[0008] Preferably, the large flange surface of the long cantilever is perpendicular to the central axis of the traction trolley, the center of the large flange surface of the long cantilever coincides with the center of the traction trolley, and the center of the locking disc coincides with the center of the traction trolley.

[0009] This invention utilizes a two-end adjustable cantilever assembly device. Through a two-section cantilever flange connection structure, it achieves both coarse and fine adjustments to the locking disc, saving time spent adjusting the overall flatness of the locking disc. This solution enables rapid adjustment of the locking disc's flatness after model changeover, reducing the number of workers required—from two people to one—significantly shortening adjustment time and reducing the number of operators. Simultaneously, the adjusted state can be observed and checked to ensure it meets requirements, improving production changeover efficiency and ultimately increasing overall production efficiency.

[0032] To more clearly describe the technical content of this utility model, the following description is provided in conjunction with specific embodiments.

[0033] The adjustable cantilever assembly of this utility model includes a traction trolley 1, a long cantilever 2, a cantilever flange 4, a locking disc 6, and an adjusting screw 7. The long cantilever 2 is connected to the traction trolley 1. The long cantilever 2 includes a large flange surface and a cantilever. One end of the cantilever is mounted on the large flange surface and is located at the center of the large flange surface. The cantilever flange 4 is mounted on the other end of the cantilever and is also connected to the locking disc 6. The adjusting screw 7 is mounted on the traction trolley 1, and the lower part of the adjusting screw 7 abuts against the long cantilever 2.

[0034] In a preferred embodiment of the present invention, the device further includes a plurality of end-face adjusting bolts 3, which are mounted on the large flange surface of the long cantilever 2, and the tightening depth of the end-face adjusting bolts 3 on the long cantilever 2 is adjustable.

[0035] In a preferred embodiment of the present invention, the device further includes a quick-adjusting bolt 5, which is screwed into the threaded hole of the long cantilever flange. The end of the quick-adjusting bolt 5 abuts against the cantilever flange 4, and the tightening depth of the quick-adjusting bolt 5 on the cantilever flange 4 supports adjustment.

[0036] In a preferred embodiment of this utility model, the large flange surface of the long cantilever 2 is perpendicular to the central axis of the traction trolley 1, the center of the large flange surface of the long cantilever 2 coincides with the center of the traction trolley 1, and the center of the locking disc 6 coincides with the center of the traction trolley 1.

[0037] This utility model is an adjustable cantilever assembly with two ends, a locking disc 6 connecting component mechanism used to connect the front section of the traction trolley 1 on the tail of a welding machine to the main reinforcing bars of the cage for traction welding. It is applicable to the square pile and pipe pile production industry. During the cage welding process, in conjunction with the traction trolley 1 on the tail of the welding machine, the locking disc 6 tooling realizes the welding of the cage. The locking disc 6 on the adjustable cantilever assembly with two ends locks the main reinforcing bar steel bar, ensuring the flatness and non-tilting of the main reinforcing bar upset head during the welding process, thereby meeting the flatness requirements of production quality.

[0038] This solution adopts a two-end adjustable flange structure, changing the existing integral cantilever assembly into a two-section connection. The structure connecting to the rear traction trolley 1 is the long cantilever 2, and the structure connecting to the front locking disc 6 is the cantilever flange 4. When changing production models or after a period of production, the locking disc 6 needs to be adjusted. The end face adjusting bolt 3 on the long cantilever 2, which is connected to the traction trolley 1 at the rear of the cantilever assembly, adjusts the mounting surface to be perpendicular to the central axis of the equipment. The adjusting screw 7 can adjust the center of the disc to coincide with the center of the equipment. The quick-adjusting bolt 5 on the cantilever flange 4, which is connected to the locking disc 6 at the front, corrects the perpendicularity of the mounting surface to the central axis of the equipment during production (when the center is not aligned). This allows for convenient and quick adjustment of the perpendicularity of the locking disc 6 to the axis, thereby greatly reducing the adjustment time for workers and improving production efficiency.

[0039] In specific embodiments of this utility model, such as Figure 1As shown, when changing production models or when the locking disc 6 needs to be adjusted for flatness, the tightening depth of the end face adjusting bolts 3 on the long cantilever 2 is adjusted to ensure that the large flange face (corresponding mounting surface) of the long cantilever 2 on the traction trolley 1 is perpendicular to the central axis of the equipment. The adjusting screw 7 is then used to make the center of the locking disc 6 coincide with the central axis of the equipment, ensuring that when the reinforcing bars are pulled, the ends of the reinforcing bars are on a single plane, perpendicular to the center of the cage reinforcement. By adjusting the tightening depth of the quick-adjusting bolts 5 on the cantilever flange 4 connected to the locking disc 6, the perpendicularity of the locking disc 6 to the central axis of the equipment can be quickly adjusted during production. This allows for slight adjustments to the flatness of the locking disc 6, and the operator is relatively close to the locking disc 6 during adjustment. One operator can easily and quickly adjust the flatness of the locking disc 6 and observe whether it meets the specified requirements, greatly reducing the time required for adjustment, decreasing the number of operators, improving the efficiency of production model changes, and ultimately increasing production efficiency.

[0040] The large flange face is perpendicular to the central axis of the traction trolley 1, and the center of the large flange face coincides with the center of the traction trolley 1.

[0041] This solution uses adjusting screws and end face adjusting screws to make the flange face at the end of the cantilever perpendicular to and coincide with the central axis of the equipment (roll welding machine); quick-adjusting screws correct the perpendicularity between the flange face and the central axis of the equipment during the production process.

[0042] The mounting surface adjusted in this scheme is perpendicular to the central axis of the equipment, and the center of the mounting surface (flange face) coincides with the central axis of the equipment, thereby ensuring that the end face of the reinforcing cage is perpendicular to the axis of the reinforcing cage and that the ends are on the same plane.

[0043] Without considering cost and subsequent maintenance, an automatic adjustment drive device can be added to the front and rear flanges to achieve automatic adjustment.

[0044] After the cantilever flange 11 at one end of the cantilever flange 4 is pressed against the flange of the locking disc 6, the locking bolt passes through the light hole of the cantilever flange 11 and is screwed into the threaded hole on the flange of the locking disc 6 to make a fast connection and lock them together.

[0045] Tighten the quick-adjusting bolt 5 into the six threaded holes of the long cantilever flange 10, with the end of the quick-adjusting bolt 5 pressing against the cantilever flange 4. The adjustment steps are as follows:

[0046] First, loosen the locking bolts and nuts on the cantilever flange 4. Then, loosen the nuts on the quick-adjusting bolts 5. Adjust the end faces of the cantilever flange 4 and the locking disc 6 by adjusting the different screwing depths of the quick-adjusting nuts until they meet the requirements. Finally, tighten the nuts on the quick-adjusting bolts 5 and the locking bolts.

[0047] The number of locking bolts is 6, the number of quick-adjusting bolts is 6, and the number of nuts is 6.

[0048] The six locking bolts secure the long cantilever to the cantilever flange. The six quick-adjusting bolts adjust the cantilever flange end face by tightening them to different positions.
