Description

Technical Field

[0001] This utility model relates to the field of valve auxiliary tools, and in particular to a portable valve opening device. Background Technology

[0002] Buried valves are valves installed in underground pipeline systems. They have good sealing performance, corrosion resistance, and pressure resistance, and can effectively control the flow of fluids in pipelines. They are widely used in gas transmission systems, water supply and drainage systems, petrochemical pipeline systems, and other scenarios.

[0003] To ensure the normal operation of various pipeline systems, buried valves need to be maintained regularly, or they need to be opened for repair when a malfunction occurs. Therefore, valve opening operations are required.

[0004] Buried valves generally have large diameters and require significant torque to open. Traditional valve opening methods typically rely on long levers, wrenches, or multiple operators, which are labor-intensive and inefficient. While current electric valve opening tools can save manpower, they lack convenient and effective anti-rotation positioning mechanisms. During force application, the valve opening tool is prone to slipping or twisting, requiring two people to secure it. This results in significant energy loss and safety hazards, impacting operational efficiency and stability. Furthermore, current electric valve opening tools are bulky and heavy, making them time-consuming and labor-intensive to move. Utility Model Content

Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0030] In the description of this utility model, references to "one embodiment" or "some embodiments" mean that one or more embodiments of the utility model include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0031] This utility model provides a portable valve opening device 100, see reference. Figure 1 The portable valve opening device 100 includes a valve opening assembly 10 and an anti-rotation assembly 20. The valve opening assembly 10 provides power and transmits torque to open the valve, realizing an efficient and labor-saving mechanized valve opening function; the anti-rotation assembly 20 counteracts the reaction force of the valve and stabilizes the valve opening device 100, ensuring operational safety and stability.

[0032] Specifically, the valve opening assembly 10 includes a power mechanism 11, a mounting plate 12, a transmission rod 14, and a valve opening head 15. The power mechanism 11 is mounted on the mounting plate 12 and connected to the upper end of the transmission rod 14. The valve opening head 15 is connected to the lower end of the transmission rod 14. The power mechanism 11 outputs rotational force, and the transmission rod 14 transmits torque from the power mechanism 11 to the valve opening head 15. The valve opening head 15 directly acts on the valve to perform the valve opening operation. The power mechanism 11 can employ existing technologies such as motors and reducers; its structure and working principle are prior art and will not be described further here.

[0033] The anti-rotation assembly 20 includes an anti-rotation rod 21, a pedal 22, and a roller 23. The upper end of the anti-rotation rod 21 is hinged to the mounting plate 12, the pedal 22 is located at the lower end of the anti-rotation rod 21, and the roller 23 is rotatably mounted on the pedal 22.

[0034] This portable valve opening device 100 is used in the opening operation of buried valves. Through a power mechanism 11, it drives the transmission rod 14 and the valve head 15 to achieve efficient torque transmission, reducing labor intensity and improving valve opening efficiency. During valve opening, the operator can stand on the pedal 22, using their own weight to provide anti-torsional support, thereby counteracting the valve's reaction force, preventing the device from sliding or twisting during force application, reducing energy loss, and improving safety and reliability. The hinged design of the anti-rotation rod 21 and the mounting plate 12 allows for flexible adjustment of the anti-rotation rod 21's tilt angle according to the valve position and site conditions. During device movement and handling, the anti-rotation component 20 can be folded up to further reduce its size, and the stable support and flexible movement characteristics of the rollers 23 reduce handling difficulty and improve portability. Operation can be completed by a single person, reducing manpower requirements.

[0035] Preferably, the transmission rod 14 and / or the anti-rotation rod 21 can be configured as a telescopic structure. (Refer to...) Figure 2 In some embodiments, the transmission rod 14 includes a first rod body 141 and a second rod body 142 sleeved outside the first rod body 141. The first rod body 141 and the second rod body 142 are locked together by a first positioning pin 143. The anti-rotation rod 21 includes a third rod body 211 and a fourth rod body 212 sleeved outside the third rod body 211. The third rod body 211 and the fourth rod body 212 are locked together by a second positioning pin 213. The telescopic structure design of the transmission rod 14 and the anti-rotation rod 21 allows the length to be adjusted according to valves with different burial depths, enhancing the adaptability and versatility of the device and meeting the needs of various working conditions.

[0036] Furthermore, referring to Figure 4The second rod body 142 is provided with a first connecting cylinder 144, and the first connecting cylinder 144 is provided with a first positioning hole 145 radially. The first positioning pin 143 passes through the first positioning hole 145 and abuts against the first rod body 141. The matching design of the first positioning pin 143 and the first positioning hole 145 enables the transmission rod 14 to be reliably locked after the length is adjusted, ensuring the stability and reliability of the device during operation.

[0037] Reference Figure 5 The fourth rod 212 is provided with a second connecting cylinder 214, and the second connecting cylinder 214 is provided with a second positioning hole 215 radially. The second positioning pin 213 passes through the second positioning hole 215 and then abuts against the third rod 211. The matching design of the second positioning pin 213 and the second positioning hole 215 ensures that the anti-rotation rod 21 can be reliably locked after the length is adjusted, ensuring the stability and reliability of the device during operation.

[0038] Reference Figure 4 A limiting plate 146 is provided at one end of the first rod 141 that is inside the second rod 142. The radial width of the limiting plate 146 is greater than the inner diameter of the first connecting cylinder 144. The limiting plate 146 is provided to prevent the transmission rod 14 from completely disengaging during the extension and retraction process, thus ensuring the integrity of the structure and operational safety.

[0039] Reference Figure 5 A limiting pin 216 is provided at one end of the third rod 211 that is inside the fourth rod 212. The limiting pin 216 protrudes radially from the outer wall of the third rod 211, and the protruding width of the limiting pin 216 is greater than the gap width between the second connecting cylinder 214 and the third rod 211. The setting of the limiting pin 216 can prevent the anti-rotation rod 21 from completely detaching during the extension and retraction process, ensuring the integrity of the structure and operational safety.

[0040] Combination Figure 2 and Figure 3 In some preferred embodiments, the power mechanism 11 is connected to the upper end of the transmission rod 14 via an adapter 13. Specifically, the upper end of the adapter 13 is connected to the output shaft 111 of the power mechanism 11, and the lower end of the adapter 13 is fixedly connected to the upper end of the transmission rod 14 via a third locating pin 131. The design of the adapter 13 facilitates the connection and disassembly of the power mechanism 11 and the transmission rod 14, improving the assembly efficiency and maintenance convenience of the device.

[0041] Furthermore, the lower end of the adapter 13 is radially provided with a third positioning hole 132, and the upper end of the transmission rod 14 is radially provided with a fourth positioning hole 147. The upper end of the transmission rod 14 passes into the interior of the lower end of the adapter 13. The third positioning hole 132 corresponds to the fourth positioning hole 147, and the third positioning pin 131 passes through the third positioning hole 132 and the fourth positioning hole 147. Through the cooperation of the third positioning hole 132, the fourth positioning hole 147 and the third positioning pin 131, a reliable connection between the power mechanism 11 and the transmission rod 14 is achieved, ensuring that the torque of the power mechanism 11 can be accurately transmitted to the transmission rod 14, thereby improving transmission efficiency and reliability.

[0042] Combination Figure 2 and Figure 4 The lower end of the transmission rod 14 is provided with a third connecting cylinder 148, and the valve opening head 15 is fixedly connected to the third connecting cylinder 148 through a fourth positioning pin 151. The cooperation between the third connecting cylinder 148 and the fourth positioning pin 151 enables the valve opening head 15 to be stably installed on the transmission rod 14, ensuring the stability and reliability of the valve opening operation.

[0043] Furthermore, a fifth positioning hole 149 is radially provided on the third connecting cylinder 148, and a sixth positioning hole 152 is correspondingly provided on the valve head 15. The valve head 15 passes into the interior of the third connecting cylinder 148, with the fifth positioning hole 149 corresponding to the sixth positioning hole 152. A fourth positioning pin 151 passes through the fifth positioning hole 149 and the sixth positioning hole 152. The connection method between the fifth positioning hole 149, the sixth positioning hole 152, and the fourth positioning pin 151 makes the installation and disassembly of the valve head 15 more convenient, facilitating the replacement of the valve head 15 with a suitable one according to different valve types, and improving the versatility of the device.

[0044] Reference Figure 1 The mounting plate 12 is also provided with a handrail 121 on its side. The handrail 121 makes it easier for operators to carry and move the device, improving the portability of the device.

[0045] Reference Figure 6 The length of the pedal 22 is perpendicular to the central axis of the anti-rotation rod 21, increasing the stability of the operator's standing position. There are two rollers 23, each rotatably mounted at one end of the pedal 22. The two rollers 23 not only provide stable support but also facilitate flexible movement of the device on the ground, reducing handling difficulty and improving portability.

[0046] During the use of the aforementioned portable valve opening device 100, the length of the transmission rod 14, the length of the anti-rotation rod 21, the tilt angle of the anti-rotation rod 21, and the type of the valve opening head 15 are first adjusted according to the actual conditions such as valve depth and valve type. After adjustment, the valve opening head 15 is engaged with the valve, and the operator stands on the pedal 22 for stable anti-rotation support. Then, the power mechanism 11 is activated, and the transmission rod 14 transmits power from the power mechanism 11 to the valve opening head 15, which directly acts on the valve to complete the valve opening operation. In the non-working state, the transmission rod 14 and the anti-rotation rod 21 are shortened and retracted. The double rollers 23 provide balanced support and smooth movement, facilitating flexible movement of the device.

[0047] This portable valve opening device is applied to the opening operation of buried valves. It achieves efficient torque transmission by driving a transmission rod and valve head through a power mechanism, reducing labor intensity and improving valve opening efficiency. Operation can be completed by a single person; the operator can stand on a footplate, providing anti-rotation support to counteract the opening torque, preventing slippage or twisting of the device during force application, reducing energy loss, and improving safety and reliability. The hinged design of the anti-rotation rod and mounting plate allows for flexible adjustment of the anti-rotation rod's tilt angle according to the valve location and site conditions. During device movement and transport, the anti-rotation component can be folded away to further reduce its size. The stable support and flexible movement characteristics of the rollers reduce transport difficulty and improve portability.

[0048] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
