Description

Technical Field

[0001] This utility model relates to the field of valve operation technology, and in particular to a valve switching tool. Background Technology

[0002] In industrial production, municipal water supply, and gas transmission, valves are key components for controlling fluid flow, and their daily operation and maintenance are crucial. Currently, most valves on the market are equipped with handwheel operation mechanisms, allowing operators to open and close the valves by rotating the handwheel. However, in actual application scenarios, the installation environments of valves are complex and diverse, causing numerous inconveniences to operation.

[0003] Some valves need to be installed in underground valve wells, which are typically 1-3 meters deep. These wells are often cramped and poorly lit, requiring workers to bend over or even squat to enter and operate them. This not only increases the physical exertion of the work but also poses safety hazards such as bumps and falls. Furthermore, the handwheel sizes of different valves vary considerably, and traditional valve operating tools are poorly adaptable, often requiring multiple sets of tools for different handwheels, increasing equipment costs and carrying burden.

[0004] Therefore, it is necessary to provide a new valve switching tool to solve the above-mentioned technical problems. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 3 The present invention provides a valve switching tool, which includes a central plate 1, a connecting rod 2, an abutting rod 4, and an adjusting component 5.

[0018] In the embodiments of this utility model, please refer to Figures 1 to 3 The center plate 1 is fitted with a coaxial outer ring 3, and multiple annularly distributed connecting rods 2 are fixedly installed between the center plate 1 and the outer ring 3. Each connecting rod 2 is fitted with a sliding seat 41 that is slidably connected, and a vertically arranged abutting rod 4 is fixedly installed at the bottom of the sliding seat 41. The outer ring 3 is fixedly installed with a coaxially arranged central plate 6 through a bracket 61. The center disk 1 is provided with a pitch adjustment component 5, which adjusts the distance between each abutment rod 4 and the central axis of the center disk 1. The pitch adjustment component 5 includes a threaded rod 51, one end of which is rotatably connected to the outer wall of the center disk 1, and the other end of which is rotatably connected to the inner wall of the outer ring 3. A driven bevel gear 52 is fixedly sleeved on the rod section of the threaded rod 51 near the center disk 1. A driving bevel gear 53 is mounted on the center disk 1 and is rotatably connected to it. The driving bevel gear 53 meshes with the driven bevel gear 52 on each threaded rod 51. The mating rod 2 corresponds to the threaded rod 51 and is distributed vertically. The threaded rod 51 passes through the sliding seat 41 on the corresponding mating rod 2 and is threadedly connected to the threaded through hole of the sliding seat 41. The pitch adjustment component 5 also includes a servo motor 54, which is fixedly mounted on the inner top wall of the central disk 6 through a frame. The output end of the servo motor 54 is fixedly connected to the connection end of the driving bevel gear 53.

[0019] It should be noted that the spacing of each abutment rod 4 is adjusted according to the size of the handwheel in the underground valve well. Specifically, the servo motor 54 is turned on to drive the active bevel gear 53 to rotate. Since the active bevel gear 53 is meshed with the driven bevel gear 52, each threaded rod 51 rotates synchronously. Since the sliding seat 41 is sleeved on the threaded rod 51 and threadedly connected to the threaded rod 51, and the sliding seat 41 is restricted by the connecting rod 2, each sliding seat 41 slides radially outward or radially inward along the threaded rod 51. Therefore, the spacing between each abutment rod 4 and the central axis of the central disk 1 can be adjusted. Then, each abutment rod 4 is inserted into the wheel cavity of the handwheel (i.e., the abutment rod 4 is inserted into the handwheel and abuts against each of the reinforcing ribs of the handwheel). Then, the telescopic rod 7 is rotated to drive the abutment rod 4 to rotate and thus open and close the valve. Therefore, this application can quickly adapt to valve handwheels of different sizes, without the need to equip multiple sets of tools for different specifications of valves, greatly reducing equipment costs and carrying burden, and is suitable for the operation of various specifications of valves in municipal, industrial and other fields.

[0020] In addition, a power supply for the servo motor 54 is embedded in the central plate 6, and an LED light electrically connected to the power supply can be installed below the central plate 6.

[0021] In this application, the threaded rod 51, the driven bevel gear 52 and the driving bevel gear 53 are all regularly maintained by the staff and coated with lubricating oil. At the same time, a protective cover for protecting the servo motor 54 is installed on the central plate 6.

[0022] In the embodiments of this utility model, please refer to Figures 1 to 3 The central plate 6 is located above the central plate 1. A telescopic rod 7 is installed on the central plate 6. The telescopic rod 7 includes a sleeve 71, which is fixedly installed on the upper plate surface of the central plate 6. A sliding rod 72 is inserted into the sleeve 71. A threaded through hole is opened on the sleeve wall near the top opening of the sleeve 71, and a threaded fastening screw A73 is inserted into the threaded through hole. A radial through hole is opened on the rod body near the top end of the sliding rod 72, and a sliding deflection rod 8 is inserted into the through hole. A handle is installed on the deflection rod 8. A threaded hole communicating with the through hole is opened on the sliding rod 72, and a threaded fastening screw B9 is inserted into the threaded hole.

[0023] It should be noted that: the center plate 1 is lowered into the underground valve well using the telescopic rod 7. Specifically, the length of the telescopic rod 7 is adjusted according to the depth of the underground valve well, and the sliding rod 72 is slid outward along the sleeve 71 until the length of the sliding rod 72 and the sleeve 71 meets the requirements. Then, the fastening screw A73 is tightened. Subsequently, each abutment rod 4 is inserted into the wheel cavity of the handwheel. By adjusting the distance between the handle of the deflection rod 8 and the sliding rod 72, the deflection rod 8 is locked using the fastening screw B9, thereby saving the rotation force of the operator.

[0024] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
