Description

Technical Field

[0001] This utility model relates to the field of hydraulic support assembly technology, and in particular to a hydraulic support hinge shaft assembly device. Background Technology

[0002] The articulation shaft assembly involves first aligning the holes of the hydraulic support body A (hereinafter referred to as body A) and assembly part B (hereinafter referred to as part B), and then pushing the articulation shaft into the hole. Currently, the articulation shaft assembly of hydraulic supports mainly relies on manual operation. First, the articulation shaft is inserted into the articulation hole of body A on the ground. This process requires workers to manually move the articulation shaft to the assembly position, align it with the articulation hole, and then push it in by hand using their own strength. At this time, the articulation shaft is locked onto body A, and then it is moved to the assembly position. Then, using lifting equipment, the hydraulic support component B to be assembled is lifted and moved steadily back to be aligned with the main body A for hole alignment and shaft installation. Since some hinge shafts are installed at a high position, workers need to stand at a high position (on adjacent hydraulic supports) to align the holes and push the shafts. During this process, the parts are heavy and have complex shapes, requiring workers to repeatedly align the holes, observe, direct, and adjust. After the hinge holes are initially aligned, the assembly workers need to use tools such as pry bars to fine-tune the components. This process may require coordination with the lifting equipment to ensure that the hinge holes are completely aligned. The workers use their own strength to push the hinge shafts in completely. Finally, bolts, nuts, and other fasteners are used to fix it, completing the assembly.

[0003] Objective disadvantages of existing technologies:

[0004] 1. The entire assembly process is labor-intensive: The hinge shaft is heavy, and the assembly process requires workers to manually pick up, move, align, and push the parts, which consumes a lot of physical strength and energy. At the same time, the assembly of the hinge shaft requires the cooperation of multiple workers, such as crane operators and assemblers, which increases the cost.

[0005] 2. Assembly carries certain safety risks: First, the hinge shaft is heavy, and workers are at risk of falling and being injured while picking it up and moving it; second, after the hinge shaft is initially installed, the main assembly body needs to be lifted and moved, which also carries the risk of falling and being injured; third, the assembly process requires workers to work at heights, and requires the coordination of overhead cranes, which also involves risks such as falling from heights, being injured, and colliding with others.

[0006] 3. Complex assembly process: During the assembly and alignment of the hinge shaft, workers cannot directly see whether the hinge holes are aligned. They can only rely on experience and whether they encounter resistance when pushing the hinge shaft in to judge whether it is aligned. They also need to use tools such as pry bars for fine-tuning, which is time-consuming and laborious. This utility model, through a CCD camera, enables workers to see the alignment status of the hinge holes and achieves automatic alignment through visual positioning. Utility Model Content

[0007] The purpose of this utility model is to provide a hydraulic support hinge shaft assembly device in order to solve the above-mentioned problems.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. An intelligent cantilever crane device is adopted, which uses an electric hoist to replace the worker's arm to grab the articulated shaft. By utilizing existing intelligent lifting tools, the labor intensity of workers is reduced and work efficiency is improved. At the same time, through intelligent equipment, the parts can be lifted from all directions.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-3 As shown, a hydraulic support hinge shaft assembly device includes a load AGV6, a frame 8 mounted on the load AGV6, an intelligent cantilever crane 1 mounted on the load AGV6 on one side of the frame 8 for lifting the hinge shaft, and a scissor lift platform 9 mounted on the load AGV6 on the other side of the frame 8; a tray 10 is mounted on the scissor lift platform 9; an electric hoist 2 for lifting is mounted on the intelligent cantilever crane 1, and a magnetic adsorption device for gripping the hinge shaft is mounted on the moving end of the electric hoist 2; the magnetic adsorption device is an electromagnet; a hinge shaft support frame 3 and a hinge lifting mechanism are provided on the frame 8, and the hinge shaft support frame 3 is driven to move up and down by the hinge lifting mechanism; an electric cylinder push rod is installed inside the hinge shaft support frame 3.

[0030] A transplanting mechanism 7 is provided between the hinged shaft support frame 3 and the upright frame 8. The transplanting mechanism 7 includes an X-axis moving mechanism, a Y-axis moving mechanism and a Z-axis moving mechanism. The X-axis moving mechanism and the Y-axis moving mechanism are both driven by screw drives, and the Z-axis moving mechanism is driven by chain drives.

[0031] A visual positioning system for visually positioning the hinge hole is installed on the hinge shaft support frame 3; the visual positioning system includes a CCD camera 5; the CCD camera 5 acquires images of the hinge hole in real time and transmits them to the worker's handheld terminal for remote monitoring and adjustment.

[0032] Working principle: The above-mentioned assembly device is used in the following steps:

[0033] Step S1: The intelligent cantilever crane 1 reduces the labor intensity of workers in grasping the articulated shaft. Workers use the magnetic attraction device of the electric hoist 2 to attract the articulated shaft, and after grasping it, move it to the position of the articulated shaft support frame 3 and put it into the articulated shaft support frame 3. The intelligent cantilever crane 1 can rotate 360" in all directions and meet the lifting and lowering requirements. At the same time, the arc of the electric hoist 2 can adapt to various articulated shaft sizes and can flexibly meet various assembly requirements.

[0034] Step S2: The lifting mechanism raises the hinge shaft support frame 3 into the air. The CCD camera 5 takes a picture of the hinge hole of the assembly body for positioning, and the coordinates are calculated in the background. The relevant information is sent to the load AGV 6, which moves according to the information to roughly align the hinge shaft support frame 3 with the hinge hole. If the discrepancy is large, the load AGV 6 can be switched to manual control for initial movement. In addition, the coordinate relationship between the hinge hole of the assembly body and the hinge hole of the assembly part is calculated and sent to the lifting equipment. This facilitates the lifting equipment to move the assembly part for hole alignment. This alignment process can be transmitted in real-time to the worker's handheld terminal via the CCD camera 5, allowing the worker to view the alignment status and easily intervene manually. The CCD camera 5 also captures images of the hinge hole in real-time and transmits them to the worker's handheld terminal for remote monitoring and adjustment.

[0035] Step S3: After the load AGV6 is initially positioned, the transplanting mechanism 7 behind the hinge shaft support frame 3 will precisely align the hinge shaft support frame 3 with the hinge hole, and achieve precise movement of the Z axis (up and down) through chain drive, and precise movement of the X axis (left and right) and Y axis (front and back) through screw drive.

[0036] Step S4: After the hinge shaft support frame 3 is aligned and close to the hinge hole of the assembly body, the hinge shaft in the support frame is pushed into the hinge hole by the electric cylinder push rod to complete the assembly. The front end of the electric cylinder push rod is a disc with a buffer rubber pad on the surface to avoid damage to the parts during the pushing process. The size of the disc meets the size of all hinge shafts.

[0037] Step S5: When performing high-altitude shaft mounting tasks, if there are special circumstances that cause the shaft mounting mechanism to be misaligned or the shaft to go out of line and cannot be adjusted or handled by handheld terminal, the worker can adjust it by riding the scissor lift platform 9 near the hinge hole.

[0038] Step S6: After pushing the hinge shaft into the hole, the entire mechanism can actively avoid and exit. The lifting mechanism hinge shaft support frame 3 descends to the designated position and repeats the above actions.

[0039] Among them, the X, Y, and Z axis movement accuracy error of the transplanting mechanism 7 is less than ±0.5mm; the thrust range of the electric cylinder push rod is 100-500N, and the disc diameter can be adapted to hinge shafts with different hole diameters.

[0040] This optimized assembly method for hydraulic support hinge shafts provides a safer and more sophisticated assembly method, especially for hinge shafts at higher positions. Compared to traditional manual handling of hinge shafts during assembly, it employs an intelligent cantilever crane (1) and an electric hoist (2) to replace workers' arms in grasping parts, reducing the labor intensity of manual picking. This cantilever crane is mounted on a mobile AGV, expanding its operational range. Furthermore, addressing the inconvenience of manual hole alignment, visual positioning is used. CCD camera scanning automatically identifies the positional status between assemblies, sending coordinates for precise positioning by relevant equipment, enhancing hole alignment accuracy and improving the overall assembly process. Additionally, video is transmitted in real-time via a CCD camera (5) to a worker's handheld terminal, allowing real-time monitoring of hinge hole alignment and ensuring high reliability. Moreover, addressing the safety concerns of working at heights, an automatic lifting, moving, and pushing mechanism for the hinge shaft is designed using motors, chains, and guide rails. Combined with CCD camera monitoring, this allows workers to complete assembly work from the ground, avoiding the safety risks associated with working at heights.

[0041] In addition, during the structural design process, the electric hoist 2 can be adapted to products of different sizes and types, and has high versatility; the component support frame of the push shaft mechanism is designed according to the maximum size of the assembled parts, which can meet the placement of all current hinge shafts; the rest of the transfer and lifting mechanisms are also universal.

[0042] In summary, compared with the traditional hydraulic support hinge shaft assembly, this patent is more convenient, can effectively improve work efficiency, reduce safety risks during the assembly process, effectively reduce enterprise costs, and enhance the enterprise image.

[0043] The intelligent cantilever crane 1, electric hoist 2, articulated shaft support frame 3, chain lifting mechanism 4, CCD camera 5, load AGV 6, transplanting mechanism 7, upright frame 8, scissor lifting platform 9, and pallet 10 are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.
