Description

Technical Field

[0001] The utility model relates to the technical field of plug valve installation, in particular to a plug valve arc piece installation mechanism and equipment. Background Art

[0002] The installation of the curved blades is a crucial step in the manufacturing and assembly of plug valves. However, current installation methods rely primarily on manual labor, which presents significant shortcomings. Specifically, before installing the plug valve, workers must manually position the two curved blades together before inserting the plug into the valve body. This process not only has low labor utilization but is also slow, significantly impacting plug valve production efficiency.

[0003] Furthermore, due to the limitations of manual operation, such as inconsistent force and angle, the arc blades often deviate from their position during installation, even moving or falling off. This not only reduces the installation accuracy of the plug valve but can also adversely affect the performance of the valve body. Furthermore, manual operation increases production costs and labor intensity, making it unsuitable for large-scale mass production. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] In the first aspect of the present application, a plug valve arc piece mounting mechanism is provided, comprising a mounting plate 1, a support sleeve 2, an inner rod 3, a rod sleeve 4, a transmission mechanism and a first drive device 5; the support sleeve 2 is connected to the mounting plate 1, the rod sleeve 4 is coaxial and movably connected to the inner side of the support sleeve 2, and the inner rod 3 is coaxial and movably connected to the inner side of the rod sleeve 4; the first end of the rod sleeve 4 extends out of the support sleeve 2 and is provided with a first push structure for pressing the first arc piece; the second end of the rod sleeve 4 extends out of the support sleeve 2 and is connected to the transmission mechanism; the first end of the inner rod 3 extends out of the first end of the rod sleeve 4 and is provided with a second push structure for pressing the second arc piece; the second end of the inner rod 3 extends out of the second end of the rod sleeve and is connected to the transmission mechanism; the first drive device 5 is used to provide power, and the transmission mechanism is used to transmit power to the inner rod 3 and the rod sleeve 4 respectively, and make the inner rod 3 and the rod sleeve 4 slide symmetrically relative to each other.

[0027] Specifically, in this embodiment, the arc piece installation device of the plug valve is fixedly supported by the mounting plate 1, and a coaxial and movably connected structure is formed by the support sleeve 2, the inner rod 3 and the rod sleeve 4. One end of the rod sleeve 4 and the inner rod 3 respectively extends out of the support sleeve 2, and is provided with a push structure for pushing the two arc pieces. The transmission mechanism is connected to the other end of the rod sleeve 4 and the inner rod 3, and is powered by the first drive device 5 to drive the transmission mechanism to work, and transmit power to the inner rod 3 and the rod sleeve 4 respectively, so that they can achieve symmetrical relative sliding. When the transmission mechanism is driven, the rod sleeve 4 and the inner rod 3 will move simultaneously but in opposite directions, and the two push structures will open, respectively pressing against the two arc pieces in the valve body, preparing for the installation of the plug.

[0028] The plug valve arc piece installation equipment replaces the traditional manual installation through mechanized operation, which significantly improves the installation efficiency and reduces the labor cost.

[0029] The symmetrical relative sliding design ensures that the two arc pieces can be pressed against the predetermined position simultaneously and accurately, so that they will not move or fall off during the installation of the plug. By maintaining the stability of the arc pieces, the accuracy and stability of the plug installation are improved.

[0030] In some embodiments, the transmission mechanism includes a first gear 6, a second gear 7, a first rocker arm 8, a second rocker arm 9, a first fixed ring 10 and a second fixed ring 11; the first gear 6 and the second gear 7 are respectively rotatably connected to the mounting plate 1 and mesh with each other, and the first driving device 5 is connected to the mounting plate 1 for driving one of the gears to rotate; one end of the first rocker arm 8 is rotatably connected to the end face of the first gear 6, and the other end is rotatably connected to the first fixed ring 10, and the first fixed ring 10 is fixedly sleeved on the outside of the second end of the rod sleeve 4; one end of the second rocker arm 9 is rotatably connected to the end face of the second gear 7, and the other end is rotatably connected to the second fixed ring 11, and the second fixed ring 11 is fixedly sleeved on the outside of the second end of the inner rod 3.

[0031] Specifically, in this embodiment, the first gear 6 and the second gear 7 are meshed. When the first drive device 5 drives one gear to rotate, the other gear also rotates. As the gears rotate, the rocker arm drives the rod sleeve 4 and the inner rod 3 to slide symmetrically relative to each other, thereby achieving automatic pushing and tightening of the arc piece. Utilizing the principle of gear meshing and the transmission principle of the rocker arm, precise control of the rod sleeve 4 and the inner rod 3 is achieved, ensuring that the arc piece is accurately tightened during installation.

[0032] In some embodiments, the first push structure is a first key bar 12 provided on the outer wall of the first end of the rod sleeve 4, and the second push structure is a second key bar 13 provided on the outer wall of the first end of the inner rod 3, and the first key bar 12 and the second key bar 13 are aligned in a straight line.

[0033] Specifically, in this embodiment, when the transmission mechanism drives the rod sleeve 4 and the inner rod 3 to slide symmetrically relative to each other, the first key bar 12 and the second key bar 13 will open relatively, respectively pressing the two arc pieces at predetermined positions, thereby ensuring the stability of the arc pieces during installation.

[0034] In some embodiments, a protective sleeve 14 is fixedly mounted on the outer side of the first end of the rod sleeve 4. The protective sleeve 14 is disposed between the first key bar 12 and the end of the support sleeve 2. The addition of the protective sleeve 14 prevents accidental contact between the first key bar 12 and the end of the support sleeve 2, reducing the risk of damage. In addition, the protective sleeve 14 enhances the durability and reliability of the plug valve.

[0035] In some embodiments, the end of the protective sleeve 14 near the support sleeve 2 is connected to the expansion port 15, which is sleeved on the outside of the support sleeve 2 to shield the end of the support sleeve 2. By adding the expansion port 15, the end of the support sleeve 2 is effectively shielded to prevent the entry of external impurities or foreign matter.

[0036] In the second aspect of the present application, a plug valve arc plate installation device is provided, including the above-mentioned installation mechanism, and the device also includes a supporting frame 16, an X-guide rail 17, a mounting seat 18 and a Z-guide rail 19; the X-guide rail 17 is horizontally connected to the upper end surface of the supporting frame 16, and the mounting seat 18 is slidably connected to the X-guide rail 17; the Z-guide rail 19 is vertically connected to the side of the mounting seat 18, and the mounting plate 1 is slidably connected to the Z-guide rail 19.

[0037] Specifically, mounting base 18 is slidably connected to X-guide rail 17 and can slide horizontally along the rail. Mounting plate 1 is slidably connected to Z-guide rail 19 and can slide vertically along the rail. Regardless of the size of the plug valve or its specific installation requirements, mounting plate 1 can adjust its position on the X and Z axes to ensure perfect alignment and precise installation with the plug valve, greatly enhancing the device's applicability.

[0038] In some embodiments, the device includes a second drive device 20, a third drive device 21, a first screw rod and a second screw rod; the first screw rod is horizontally rotated and connected to the supporting frame 16, the second drive device 20 is fixed to the supporting frame 16 and connected to the first screw rod, and the mounting seat 18 is provided with a first screw hole that cooperates with the first screw rod. The second drive device 20 is used to drive the first screw rod to rotate, driving the mounting seat 18 to move horizontally; the second screw rod is vertically rotated and connected to the mounting seat 18, the third drive device 21 is fixed to the top of the mounting seat 18 and connected to the second screw rod, the mounting plate 1 is provided with a second screw hole that cooperates with the second screw rod, and the third drive device 21 is used to drive the second screw rod to rotate, driving the mounting plate 1 to move vertically.

[0039] Specifically, when the second drive device 20 is activated, it drives the first screw to rotate. Since the mounting base is provided with a first screw hole that mates with the first screw, the mounting base 18 will subsequently move horizontally. Similarly, the third drive device 21 is fixed to the top of the mounting base 18 and connected to the vertically rotating second screw. When the third drive device 21 is activated, it drives the second screw to rotate. Since the mounting plate 1 is provided with a second screw hole that mates with the second screw, the mounting plate 1 will subsequently move vertically. This embodiment realizes automated control of the mounting base 18 and the mounting plate 1 in the horizontal and vertical directions, improving the installation efficiency of the plug valve.
