AI Technical Summary
但在实际应用中，现有技术仍存在明显不足：一方面，纯电控单轨吊依赖防爆电气元件，一旦元件失效易导致设备失控，在煤矿等存在易燃易爆气体的高危环境下，极易引发爆炸等安全事故，存在严重安全隐患；另一方面，手动控制的手柄杆位置过高，工人操作时需频繁抬臂或踮脚，不仅增加劳动强度，还可能因操作不便影响控制精度，降低作业效率，为此本专利提出多路阀拉链换向机构来解决上述问题
通过将手柄轴安装在拉链机构转块的中心，并用圆柱销与拉链机构转块进行过盈配合，使其固定在一起，并且拉链机构转块的两端转动连接有拉链机构绳座，通过拉链限位挡板对拉链机构转块旋转角度进行限制，钢丝绳穿过拉链限位挡板与拉链机构绳座进行安装。当一个拉杆受到一个向下的力，拉链机构转块相应的一端向下倾斜，带动手柄轴转动，手柄轴转动带动安装轴运动，安装轴带动手柄座链接块运动，从而带动阀芯相对移动，通过采用天平杠杆式拉链机构转块和拉链限位挡板的设计，显著降低了工人的操作难度，工人不再需要频繁弯腰或踮脚，减少了疲劳感，从而提高了工作效率。此外，拉链限位挡板的加入确保了换向操作的精确性，避免了因误操作引发的安全隐患。不仅提高了操作便捷性，还增强了系统的安全性和可靠性，将原有手柄操控方式优化为钢丝绳牵引式阀芯切换结构，通过拉拽钢丝绳实现阀芯位置的精准调控，相较于传统手柄操作，该设计可有效提升操控便捷性与空间适应性，尤其适用于狭小安装环境或远距离操控场景，同时通过钢丝绳的柔性传动特性，降低机械干涉风险，为阀芯切换提供更稳定、高效的操作解决方案。

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of reversing mechanisms, specifically a multi-way valve zipper reversing mechanism. Background Technology
[0002] In high-risk environments such as coal mines, monorails, as transportation devices suspended under a single track beam, are widely used for horizontal transportation of goods and personnel due to their advantages of small space occupation and flexible route planning. They can be divided into three categories according to load capacity: light, medium, and heavy. With technological advancements, they have been upgraded to semi-automatic control modes, and the widespread adoption of electrically controlled and manual-electrically controlled combined models has significantly improved their level of intelligence. However, in practical applications, existing technologies still have significant shortcomings: On the one hand, purely electrically controlled monorail cranes rely on explosion-proof electrical components. Once these components fail, the equipment is prone to malfunction. In high-risk environments such as coal mines where flammable and explosive gases are present, this can easily lead to explosions and other safety accidents, posing serious safety hazards. On the other hand, the manual control handle is positioned too high, requiring workers to frequently raise their arms or stand on tiptoe, which not only increases labor intensity but may also affect control accuracy and reduce work efficiency due to inconvenient operation. Therefore, this patent proposes a multi-way valve zipper reversing mechanism to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a multi-way valve zipper reversing mechanism to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-way valve zipper reversing mechanism, including a valve core, a handle seat valve block, and a steel wire rope. A handle shaft is rotatably connected through the handle seat valve block. A zipper mechanism rotating block is fixed to one end of the handle shaft. The handle shaft passes through the center of the zipper mechanism rotating block. A cylindrical pin is installed on the handle shaft, and the cylindrical pin is interference-fitted with the zipper mechanism rotating block to fix them together. A zipper mechanism rope seat is installed at the top of the steel wire rope, and the zipper mechanism rope seat is rotatably connected to the zipper mechanism rotating block. A handle seat limiting support plate is fixed at the bottom of the handle seat valve block, and a zipper limiting baffle is fixed at the bottom of the handle seat limiting support plate. The steel wire rope passes through the zipper limiting baffle. A handle seat limiting steel pad is fixed at the top of the handle seat valve block. A handle seat connecting block is rotatably connected to the bottom of the valve core. The handle seat connecting block is located inside the handle seat valve block. An installation shaft is provided inside the handle shaft, and the handle seat connecting block and the installation shaft are rotatably connected.
[0005] Preferably, a zipper mechanism pin is inserted into the overlapping hole of the zipper mechanism rotating block end and the zipper mechanism rope seat, the overlapping hole of the valve core and the handle seat connecting block, and the overlapping hole of the handle seat connecting block and the mounting shaft.
[0006] Preferably, a retaining ring is engaged with the outer wall of one end of the zipper mechanism pin to prevent the zipper mechanism pin from disengaging axially.
[0007] Preferably, a valve core mounting screw is screwed to the top of the valve core.
[0008] Preferably, multiple M5-50 screws are screwed between the handle seat limiting support plate, the handle seat valve block, and the handle seat limiting steel washer.
[0009] Preferably, a plurality of M6-12 screws are screwed between the zipper limiting baffle and the handle seat limiting support plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By mounting the handle shaft at the center of the zipper mechanism's rotating block and securing it with a cylindrical pin through an interference fit, the zipper mechanism's rotating block is fixed in place. Zipper mechanism rope seats are rotatably connected to both ends of the rotating block. A zipper limiting baffle restricts the rotation angle of the rotating block, and a steel wire rope passes through the limiting baffle and is installed with the rope seats. When a lever is subjected to a downward force, the corresponding end of the zipper mechanism's rotating block tilts downward, causing the handle shaft to rotate. This rotation drives the mounting shaft, which in turn moves the handle seat connecting block, thereby causing the valve core to move relative to it. The design of the zipper mechanism's rotating block and limiting baffle, using a balance lever type, significantly reduces the operator's difficulty. Workers no longer need to frequently bend over or tiptoe, reducing fatigue and improving work efficiency. Furthermore, the addition of the limiting baffle ensures the accuracy of the reversing operation, preventing safety hazards caused by misoperation. This design not only improves ease of operation but also enhances system safety and reliability. The original handle control method has been optimized into a wire rope traction valve core switching structure. By pulling the wire rope, the valve core position can be precisely controlled. Compared with traditional handle operation, this design can effectively improve ease of operation and spatial adaptability, especially suitable for confined installation environments or long-distance operation scenarios. At the same time, the flexible transmission characteristics of the wire rope reduce the risk of mechanical interference, providing a more stable and efficient operation solution for valve core switching.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] In high-risk environments such as coal mines, monorails, as transportation devices suspended under a single track beam, are widely used for horizontal transport of goods and personnel due to their advantages of small space occupation and flexible route planning. They can be divided into light, medium, and heavy-duty types according to load capacity, and with technological advancements, they have been upgraded to semi-automatic control modes. The widespread adoption of electrically controlled and manual-electrically combined models has significantly improved their level of intelligence. However, in practical applications, existing technologies still have significant shortcomings: Firstly, purely electrically controlled monorails rely on explosion-proof electrical components. If these components fail, it can easily lead to equipment malfunction, posing a serious safety hazard in high-risk environments such as coal mines where flammable and explosive gases are present. Secondly, the manual control lever is positioned too high, requiring workers to frequently lift it during operation. Using arms or tiptoeing not only increases labor intensity but may also affect control accuracy and reduce work efficiency due to inconvenient operation. The multi-way valve zipper reversing mechanism provided by this utility model installs the handle shaft 5 at the center of the zipper mechanism rotating block 11 and uses a cylindrical pin to press-fit the zipper mechanism rotating block 11 together, and the two ends of the zipper mechanism rotating block 11 are rotatably connected to the zipper mechanism rope seat 14. The rotation angle of the zipper mechanism rotating block 11 is limited by the zipper limiting baffle 9, and the steel wire rope 15 passes through the zipper limiting baffle 9 and is installed with the zipper mechanism rope seat 14. When a lever is subjected to a downward force, the corresponding end of the zipper mechanism rotating block 11 tilts downward, causing the handle shaft 5 to rotate. The rotation of the handle shaft 5 drives the mounting shaft to move, which in turn drives the handle seat connecting block 4 to move, thereby causing the valve core 2 to move relative to it. By adopting the design of the balance lever type zipper mechanism rotating block 11 and the zipper limiting baffle 9, the difficulty of operation for workers is significantly reduced. Workers no longer need to frequently bend over or tiptoe, reducing fatigue and thus improving work efficiency. In addition, the addition of the zipper limiting baffle 9 ensures the accuracy of the reversing operation and avoids safety hazards caused by misoperation. This design not only improves ease of operation but also enhances the safety and reliability of the system. The original handle control method is optimized into a wire rope traction valve core switching structure. The position of valve core 2 can be precisely controlled by pulling the wire rope 15. Compared with the traditional handle operation, this design can effectively improve the ease of operation and spatial adaptability, especially suitable for confined installation environments or long-distance operation scenarios. At the same time, the flexible transmission characteristics of the wire rope 15 reduce the risk of mechanical interference, providing a more stable and efficient operation solution for valve core 2 switching.
[0015] like Figures 1-4As shown, this utility model provides a technical solution: a multi-way valve zipper reversing mechanism, including a valve core 2, a handle seat valve block 6, and a steel wire rope 15. A handle shaft 5 is rotatably connected through the handle seat valve block 6. One end of the handle shaft 5 is fixed to a zipper mechanism rotating block 11. The handle shaft 5 passes through the center of the zipper mechanism rotating block 11. A cylindrical pin is installed on the handle shaft 5, and the cylindrical pin is press-fitted with the zipper mechanism rotating block 11 to fix them together. A zipper mechanism rope seat 14 is installed at the top of the steel wire rope 15. The mechanism rope seat 14 is rotatably connected to the zipper mechanism rotating block 11. The bottom end of the handle seat valve block 6 is fixed with a handle seat limiting support plate 7. The bottom end of the handle seat limiting support plate 7 is fixed with a zipper limiting baffle 9. The wire rope 15 passes through the zipper limiting baffle 9. The top end of the handle seat valve block 6 is fixed with a handle seat limiting steel pad 3. The bottom end of the valve core 2 is rotatably connected with a handle seat connecting block 4. The handle seat connecting block 4 is located inside the handle seat valve block 6. An installation shaft is provided inside the handle shaft 5. The handle seat connecting block 4 and the installation shaft are rotatably connected.
[0016] It is important to note that by installing the handle shaft 5 at the center of the zipper mechanism rotating block 11 and using a cylindrical pin to press-fit it together, the zipper mechanism rotating block 11 is fixed in place. Both ends of the zipper mechanism rotating block 11 are rotatably connected to zipper mechanism rope seats 14. The rotation angle of the zipper mechanism rotating block 11 is limited by the zipper limiting baffle 9. The steel wire rope 15 passes through the zipper limiting baffle 9 and is installed with the zipper mechanism rope seats 14. When a lever is subjected to a downward force, the corresponding end of the zipper mechanism rotating block 11 tilts downward, causing the handle shaft 5 to rotate. The rotation of the handle shaft 5 drives the mounting shaft, which in turn drives the handle seat connecting block 4, thereby causing the valve core 2 to move relative to it. By adopting the design of the balance lever-type zipper mechanism rotating block 11 and the zipper limiting baffle 9, the operational difficulty for workers is significantly reduced. Workers no longer need to frequently bend over or stand on tiptoe, reducing fatigue and improving work efficiency. Furthermore, the addition of the zipper limiting baffle 9 ensures the accuracy of the reversing operation and avoids safety hazards caused by misoperation. This design not only improves ease of operation but also enhances the safety and reliability of the system. The original handle control method is optimized into a wire rope traction valve core switching structure. The position of valve core 2 can be precisely controlled by pulling the wire rope 15. Compared with the traditional handle operation, this design can effectively improve the ease of operation and spatial adaptability, especially suitable for confined installation environments or long-distance operation scenarios. At the same time, the flexible transmission characteristics of the wire rope 15 reduce the risk of mechanical interference, providing a more stable and efficient operation solution for valve core 2 switching.
[0017] like Figure 4As shown, zipper mechanism pins 12 are inserted into the overlapping holes of the zipper mechanism rotating block 11 end and the zipper mechanism rope seat 14, the overlapping holes of the valve core 2 and the handle seat connecting block 4, and the overlapping holes of the handle seat connecting block 4 and the mounting shaft. A retaining ring 13 is engaged with the outer wall of one end of the zipper mechanism pin 12 to prevent the zipper mechanism pin 12 from disengaging axially. A valve core mounting screw 1 is screwed to the top of the valve core 2. Multiple M5-50 screws 8 are screwed between the handle seat limiting support plate 7, the handle seat valve block 6, and the handle seat limiting steel pad 3. Multiple M6-12 screws 10 are screwed between the zipper limiting baffle 9 and the handle seat limiting support plate 7.
[0018] It should be noted that the device is installed at the tail end of the manual reversing assembly. The handle shaft 5 at the outer end of the handle seat valve block 6 is engaged with the zipper mechanism rotating block 11. Then, zipper mechanism rope seats 14 are added to both ends of the zipper mechanism rotating block 11, and steel wire ropes 15 are installed on the zipper mechanism rope seats 14. By applying tension to the steel wire ropes 15, the zipper mechanism rotating block 11 is rotated, which in turn drives the handle shaft 5 to rotate, thereby controlling the displacement of the valve core 2.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
