Description

Technical Field

[0001] This utility model relates to the field of hydraulic support structure flipping technology, and in particular to an auxiliary flipping device for hydraulic support structure. Background Technology

[0002] The tilting of hydraulic support structural components is currently a precise operation involving both overhead cranes and manual labor, requiring strict adherence to safety regulations and technical procedures. Before the tilting operation begins, technicians must create lifting diagrams for each specific structural component; see [link to diagram]. Figure 1 This serves as the theoretical guide for the flipping operation; before the flipping operation begins, special lifting equipment must be configured for different structural components, and the condition of the lifting chain must be carefully checked; during the flipping operation, one or more workers need to cooperate with the bridge crane to flip the structural components, and the whole process requires careful observation and is highly dangerous.

[0003] Combination Figure 1 and Figure 2 Traditional structural component flipping methods have the following shortcomings:

[0004] First, the lifting system has defects. During the dynamic overturning process, local compression may cause the chain link stress to exceed the limit. The included angle between the hinges exceeds 120 degrees, which will increase the stress on the chain and increase the danger. It may exceed the yield limit of the chain. At the same time, there is a risk of "pseudo-redundancy" in the four lifting chains. That is, if one chain fails, it may cause a chain breakage under the impact of the overturning load.

[0005] Secondly, there is a risk of oversight in the coordination between workers and the bridge crane. If the center of gravity of a structural component flips over an adjacent point, there will be a discrepancy between theoretical calculations and actual operation. Workers may not react in a timely manner, and there may be misinterpretations in the hand gestures between the worker flipping the component and the bridge crane operator. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an auxiliary tilting device for hydraulic support structure components.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the hydraulic support structure auxiliary flipping device of this utility model includes a base, a first flipping mechanism, and a plurality of second flipping mechanisms. The first flipping mechanism is disposed on one side of the base, and the plurality of second flipping mechanisms are disposed on the other side of the base and arranged side by side.

[0010] Both the first and second flipping mechanisms include a top plate, multiple stop rods, and at least one hydraulic cylinder. The first end of the hydraulic cylinder is hinged to the base, and the second end of the hydraulic cylinder is hinged to the top plate. The stop rods are perpendicularly connected to the first side of the top plate, and the first side of the top plate is rotatably connected to the base. The hydraulic cylinder can drive the top plate to rotate between a horizontal and a vertical state. When the top plate is in a horizontal or vertical state, the top plates of the multiple second flipping mechanisms are all in the same plane. When the top plate is in a vertical state, the stop rods of the first and second flipping mechanisms are staggered.

[0011] Optionally, the hinge position of the first end of the hydraulic cylinder to the base is close to the first side of the top plate; the hinge position of the second end of the hydraulic cylinder to the top plate is close to the second side of the top plate, and the first side and the second side of the top plate are a pair of opposite sides.

[0012] Optionally, the hydraulic support structure auxiliary tilting device includes three second tilting mechanisms.

[0013] Optionally, each of the second tilting mechanisms includes one of the hydraulic cylinders.

[0014] Optionally, the first tilting mechanism includes three hydraulic cylinders, which are spaced apart.

[0015] Optionally, the base includes a mounting frame and a plurality of fixed anchor points disposed on the mounting frame. The mounting frame is disposed on the ground, and the cylinder body of the hydraulic cylinder and the top plate are both hinged to the mounting frame.

[0016] Optionally, the mounting frame has a left-right symmetrical structure, and a boss is provided along the axis of symmetry of the mounting frame. The top plates of the first flipping mechanism and the second flipping mechanism are respectively hinged to the two sides of the top of the boss.

[0017] Optionally, the base also includes a plurality of support columns, which are vertically arranged on the mounting frame. When the top plate is in a horizontal state, the bottom plate of the top plate abuts against the support columns.

[0018] Optionally, the base may also include a protective frame and multiple protective posts;

[0019] The protective frame is connected to the mounting frame, and the protective frame is arranged around the mounting frame. The multiple protective columns are all vertically installed on the protective frame.

[0020] (III) Beneficial Effects

[0021] The top plates of multiple second flipping mechanisms flip individually under the drive of their respective hydraulic cylinders. The width of the spliced ​​top plates is controlled by controlling the number of flipping movements, which is suitable for structural components of different lengths and improves the flexibility of the device.

[0022] The entire tilting process takes place on the ground, keeping operators away from the tilting mechanism and avoiding the need for overhead crane operations, thus reducing safety hazards and improving the safety of the tilting operation. The entire tilting process is driven by a hydraulic system, making it simple to operate, safe and efficient, with low maintenance and upkeep costs and frequency. The entire tilting operation reduces manual intervention, saving human resources.

[0023] This invention employs a double-support, double-connection method, changing the longitudinal tilting of structural components such as top beams, which previously required a bridge crane and manual operation, to a lateral tilting method. This effectively improves the efficiency of the tilting operation and reduces labor intensity and safety risks. Furthermore, the device's simple structural design facilitates maintenance and upkeep, providing convenience for the production and installation of hydraulic support structural components.

[0033] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 4 The orientation is used as a reference.

[0034] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0035] like Figures 3 to 5 As shown, this utility model provides an auxiliary tilting device for hydraulic support structural components, used to tilt the top beam and other structural components of a hydraulic support by 180 degrees. The auxiliary tilting device includes a base 1, a first tilting mechanism 2, and multiple second tilting mechanisms 3. (See also...) Figure 3 In the diagram, the horizontal direction is defined as the length direction of base 1, and the vertical direction is defined as the width direction of base 1. The first flipping mechanism 2 is located on one side of base 1. Figure 3 The center is located on the left side of the base 1, and multiple second flipping mechanisms 3 are located on the other side of the base 1. Figure 3 Located on the right side of the base 1, multiple second flipping mechanisms 3 are arranged side by side along the longitudinal direction of the base 1. The number of second flipping mechanisms 3 can be customized according to requirements, and the positions of the first flipping mechanism 2 and the second flipping mechanism 3 can be interchanged.

[0036] See Figure 4Both the first flipping mechanism 2 and the second flipping mechanism 3 include a top plate 21, multiple stop levers 22, and at least one hydraulic cylinder 23. The first end of the hydraulic cylinder 23 is hinged to the base 1, and the second end of the hydraulic cylinder 23 is hinged to the top plate 21. In a preferred embodiment, the end of the cylinder body of the hydraulic cylinder 23 is hinged to the base 1, and the end of the piston rod of the hydraulic cylinder 23 is hinged to the top plate 21. Alternatively, the hydraulic cylinder 23 can be inverted, i.e., the end of the cylinder body is hinged to the top plate 21, and the end of the piston rod is hinged to the base 1. The hydraulic cylinder 23 is controlled by a two-way lock and a safety valve, improving the installability of the hydraulic cylinder 23. Furthermore, the hydraulic cylinder 23 can be locked at any point during its extension and retraction, thereby controlling the flipping angle of the top plate 21. The top plate 21 can stop at any angle within the range of 0 to 90 degrees. The specifications of the hydraulic cylinder 23 can be set according to the maximum weight of the structural component to be flipped, ensuring that the hydraulic cylinder 23 can drive the top plate 21 and the structural component to flip together. The stop bar 22 is vertically connected to the first side of the top plate 21 to restrict the movement of the structural component to be flipped during the flipping process. The first side of the top plate 21 is the side rotatably connected to the base 1, and the first side serves as the axis of rotation. Specifically, multiple connecting seats are provided on the lower surface of the top plate 21 close to the first side, and the connecting seats are rotatably connected to the base 1 via the axis of rotation. During the extension and retraction of the hydraulic cylinder 23, the top plate 21 can be driven to rotate 90 degrees between a horizontal and a vertical state. See [reference needed]. Figure 4 and Figure 5 When the top plate 21 is in a horizontal or vertical state, the top plates 21 of the multiple second flipping mechanisms 3 are all in the same plane, see [reference]. Figure 3 The top plates 21 of the multiple second flipping mechanisms 3 are flipped individually under the drive of their respective hydraulic cylinders 23. The width of the spliced ​​multiple top plates 21 is controlled by controlling the number of flipping movements, which is suitable for structural components of different lengths and improves the flexibility of the device.

[0037] During the flipping process, the structural component slides down the top plate 21 under its own weight until it abuts against the stop bar 22. The stop bar restricts the movement of the structural component to be flipped, preventing it from slipping off the top plate 21. When the top plate 21 is in a vertical position, the stop bars 22 of the first flipping mechanism 2 and the second flipping mechanism 3 are staggered. When the structural component needs to be flipped, the top plate 21 is in a horizontal position. (See...) Figure 4 The structural component is placed on multiple top plates 21 on the right side of the base 1. The top plate 21 of the first flipping mechanism 2 flips to a vertical position. Then, according to the top plate 21 that the structural component is in contact with, the corresponding second flipping mechanism 3 is activated to flip, and the second flipping mechanism 3 flips to a vertical position. See [link to relevant documentation]. Figure 5At this point, the structural component slides down to abut against the stop bar 22 and rotates 90 degrees with the top plate 21. The stops of both the first and second tilting mechanisms 2 and 3 abut against the structural component. When the top plate 21 of the first tilting mechanism 2 rotates, it is in a horizontal state, and the structural component rotates another 90 degrees with the top plate 21, thus achieving a 180-degree rotation of the structure. Alternatively, a reverse operation can be used, placing the structural component first on the top plate 21 located on the left side of the base 1 before tilting. The entire tilting process is carried out on the ground, keeping operators away from the tilting mechanism, avoiding overhead crane operations, reducing safety hazards, and improving the safety of the tilting operation. The entire tilting process is driven by a hydraulic system, making it simple to operate, safe, efficient, and with low maintenance and upkeep costs and frequency. The entire tilting operation reduces manual intervention, saving human resources.

[0038] This invention employs a double-support, double-connection method, transforming the suspended rotation of structural components such as the top beam, which was previously operated by a bridge crane and manual labor, into a ground-level rotation along with the top plate 21. This effectively improves the efficiency of the rotation operation and reduces labor intensity and safety risks. Furthermore, the device's simple structural design facilitates maintenance and upkeep, providing convenience for the production and installation of hydraulic support structural components.

[0039] Preferably, such as Figure 4 As shown, the first end of the hydraulic cylinder 23 is hinged to the base 1 near the first side of the top plate 21; the second end of the hydraulic cylinder 23 is hinged to the top plate 21 near the second side of the top plate 21. The first side and the second side of the top plate 21 are a pair of opposite sides. When the hydraulic cylinder 23 extends and retracts, it can drive the top plate 21 to rotate between the horizontal and vertical states.

[0040] In a preferred embodiment, the hydraulic support structure auxiliary tilting device includes three second tilting mechanisms 3 arranged side by side, and the top plate 21 of each second tilting mechanism 3 is driven by a hydraulic cylinder 23.

[0041] In a preferred embodiment, the first flipping mechanism 2 includes three hydraulic cylinders 23, which are spaced apart and work together to drive the top plate 21 of the first flipping mechanism 2 to flip.

[0042] See Figure 4 and Figure 5 The base 1 includes a mounting frame 11 and multiple fixed anchor points 12 set on the mounting frame 11. The mounting frame 11 serves as the supporting foundation for the entire device and is assembled from square steel to reduce the weight of the entire base. The cylinder body and top plate 21 of the hydraulic cylinder 23 are both hinged to the mounting frame 11. The mounting frame 11 is installed on the ground through multiple fixed anchor points 12, which facilitates installation and also facilitates the disassembly, hoisting, and transportation of the entire device.

[0043] Specifically, the mounting frame 11 has a symmetrical structure, and a boss 13 is provided along the axis of symmetry of the mounting frame 11 for mounting the top plates 21 of the first flipping mechanism 2 and the second flipping mechanism 3. The top plates 21 of the first flipping mechanism 2 and the second flipping mechanism 3 are respectively hinged to the two sides of the top of the boss 13. When the top plate 21 is in a vertical state, the top of the boss 13 also serves as a support platform for the stop bar 22, supporting both ends of the stop bar 22 and improving the support strength of the stop bar 22.

[0044] Furthermore, the base 1 also includes multiple support columns 14, which are vertically mounted on the mounting frame 11. When the top plate 21 is in a horizontal state, the bottom plate of the top plate 21 abuts against the support columns 14, thereby increasing the support strength of the top plate 21.

[0045] Furthermore, the base 1 also includes a protective frame 15 and multiple protective posts 16. The protective frame 15 is connected to the mounting frame 11 and is arranged around the mounting frame 11. The multiple protective posts 16 are all vertically installed on the protective frame 15. Specifically, protective frames 15 are welded to the front and rear sides of the base 1. A preset installation distance is set between the protective frames 15 and the base 1. Multiple protective posts 16 are installed at intervals on the protective frames 15. Isolation plates or isolation strips can also be set between the protective posts 16 to prevent workers from entering the work area and ensure the safety of the operation process.
