Description

Technical Field

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

[0002] Water supply pipes, fire protection pipes, and industrial water pipes typically need to be laid underground, requiring the installation of underground valve wells in appropriate locations. However, pipeline repairs and valve maintenance require frequent valve opening and closing, and entering valve wells constitutes confined space work, posing certain risks.

[0003] Underground well valve handwheels typically employ a multi-spoke design to adapt to different operating environments and needs. Existing underground well valve switching fixtures use a fixed three-jaw structure, which only accommodates three-spoke valve handwheels. This results in difficulties or even failure to operate some non-three-spoke valve handwheels. Therefore, a solution to address these issues is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a switching fixture to solve the problem of low compatibility of the switching fixture with valve handwheels in the prior art.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A switch fixture includes an operating component and a positioning component. The positioning component is connected to one end of the operating component and includes a positioning element with multiple positioning holes. The positioning component also includes multiple positioning rods. One positioning rod is movably inserted into one of the positioning holes and protrudes from the positioning hole. The side wall of the positioning rod can abut against the opening of a valve handwheel. Rotation of the positioning element can cause the positioning rod to push against the opening of the valve handwheel, thereby driving the valve handwheel to rotate.

[0007] Optionally, the positioning element is disc-shaped, and the operating component is connected to the center of the positioning element.

[0008] Optionally, the positioning holes are all elongated holes, and the positioning holes extend along the diameter direction of the positioning element.

[0009] Optionally, the positioning hole wall is provided with internal threads, the positioning rod outer peripheral wall is provided with external threads, and the positioning rod and the positioning hole are threadedly engaged.

[0010] Optionally, the plurality of positioning holes are located on the same circumference.

[0011] Optionally, the number of positioning rods is three, and the center of the positioning element is located within the triangle formed by the three positioning rods.

[0012] Optionally, the operating component includes a grip and a connector, both of which are rod-shaped. One end of the connector is connected to the middle of the grip along its own length, and the other end is connected to the center of the positioning component.

[0013] Optionally, the connector is a retractable structure.

[0014] Optionally, a reinforcing member is also connected between the connector and the positioning member.

[0015] Optionally, the connector is rotatably connected to the gripper, a ratchet is provided at the end of the connector away from the positioning member, and a pawl is provided on the gripper, with the ratchet engaging with the pawl.

[0016] The beneficial effects of this utility model are:

[0017] This utility model proposes a switch fixture, including an operating component and a positioning component. The positioning component is connected to one end of the operating component and includes a positioning element with multiple positioning holes. The positioning component also includes multiple positioning rods, each of which is movably inserted into a positioning hole and protrudes from it. The side wall of the positioning rod abuts against the opening of a valve handwheel. Rotation of the positioning element causes the positioning rod to push against the opening of the valve handwheel, thereby rotating the handwheel. By setting the positioning holes and positioning rods, the positioning rods can be switched and installed in different positioning holes when dealing with different types of valve handwheels, ensuring that the side wall of the positioning rod abuts against the opening of the valve handwheel. Thus, when the operating component rotates the positioning element, the positioning rod pushes against the opening of the valve handwheel, causing it to rotate. In other words, by switching the positioning rods to be installed in different positioning holes, different types of valve handwheels can be driven to rotate by the positioning rods, improving the adaptability of the switch fixture to different types of valve handwheels.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This embodiment proposes a switch tooling to solve the problem of low compatibility of existing switch tooling with valve handwheels.

[0035] like Figures 1-2 As shown, the switch fixture includes an operating component 1 and a positioning component 2. The positioning component 2 is connected to one end of the operating component 1. The positioning component 2 includes a positioning element 21 with multiple positioning holes 211. The positioning component 2 also includes multiple positioning rods 22. A positioning rod 22 can be movably inserted into a positioning hole 211 and protrude from the positioning hole 211. The side wall of the positioning rod 22 can abut against the opening of the valve handwheel 100. The rotation of the positioning element 21 can cause the positioning rod 22 to push against the opening of the valve handwheel 100, thereby driving the valve handwheel 100 to rotate.

[0036] Understandably, when it is necessary to open or close the valves in the valve well, workers generally need to climb into the valve well to turn the valve handwheel 100. However, the working space for workers inside the valve well is limited, which can easily cause bumps and injuries, and there is even a risk of the valve well collapsing. Therefore, a switching tool is generally used to open or close the valves from the top of the well. Although the existing switching tools can reach into the well to turn the three-spoke valve handwheel 100, they are not effectively compatible with other models of valve handwheels 100. The switching fixture proposed in this embodiment allows the operator to extend the positioning component 2 to the downhole valve via the operating component 1. From the surface, the positioning rods 22 can be inserted into the required positioning holes 211 according to the model of the valve handwheel 100. This allows the sidewalls of multiple positioning rods 22 to abut against the exposed rods of the corresponding valve handwheel 100. When the operating component 1 is rotated, the positioning component 2 connected to it rotates accordingly, and the positioning rods 22 push against the exposed rods of the valve handwheel 100, causing the valve handwheel 100 to rotate and thus completing the valve opening and closing operation. In other words, by switching the positioning rods 22 to be installed in different positioning holes 211, different models of valve handwheels 100 can be driven to rotate by the positioning rods 22, improving the adaptability of the switching fixture to different models of valve handwheels 100.

[0037] It should be noted that the number of positioning holes 211 is equal to or greater than the number of positioning rods 22. When the number of positioning holes 211 is the same, the positioning rods 22 and positioning holes 211 are matched one by one. When the number of positioning holes 211 is greater than the number of positioning rods 22, the positioning rods 22 are inserted into some of the positioning holes 211.

[0038] like Figure 1 As shown, optionally, the operating component 1 includes a grip 11 and a connector 12. Both the grip 11 and the connector 12 are rod-shaped. One end of the connector 12 is connected to the middle of the grip 11 along its length, and the other end is connected to the center of the positioning member 21. This design makes the operating component 1 lighter and more portable, improving the operability of the operator. In addition, this design makes the grip 11 easier to operate, improving the user experience.

[0039] For example, the gripper 11 and the connector 12 are made of stainless steel tubing with a diameter of 40mm-50mm and a wall thickness of 2mm-4mm. This design can reduce the weight of the operating component 1 while ensuring its structural strength, thus improving the structural rationality of the switch fixture. Of course, the dimensions and wall thickness of the gripper 11 and the connector 12 can also be selected from other values, but this is not the focus of this embodiment and will not be limited in detail here.

[0040] Optionally, the connector 12 is a telescopic structure. This feature allows the length of the connector 12 to be adjusted, enabling the positioning component 2 to engage with the valve handwheel 100 when dealing with valve wells of different depths. It also allows the switch fixture to be adjusted to a height suitable for operator use, thereby improving the adaptability of the switch fixture and the user experience.

[0041] For example, the connector 12 is a multi-stage telescopic sleeve, and each stage of the telescopic sleeve is provided with a locking hole and a locking element. The locking element is elastically disposed on the telescopic sleeve and can extend into the locking hole on the adjacent telescopic sleeve. This configuration allows the connector 12 to extend or lock by pressing the locking element, which is simple and reliable and improves the reliability of the switch tooling.

[0042] It is worth mentioning that in other embodiments, the connector 12 can also be other types of telescopic components. Commercially available telescopic components can be used, and no further restrictions are imposed here.

[0043] Optionally, a reinforcing member 23 is also connected between the connector 12 and the positioning member 21. This arrangement can improve the connection strength between the connector 12 and the positioning member 21, thereby improving the reliability of the switch tooling.

[0044] For example, the reinforcing member 23 is triangular in shape, and its two right-angled sides are respectively attached to the connector 12 and the positioning member 21. This arrangement further improves the stability of the reinforcing member 23, thereby enhancing the connection strength between the connector 12 and the positioning member 21.

[0045] Optionally, the connector 12 is rotatably connected to the gripper 11. A ratchet is provided at the end of the connector 12 away from the positioning member 21, and a pawl is provided on the gripper 11. The ratchet and pawl cooperate with each other. This arrangement allows the operator to rotate the connector 12 without fully rotating the gripper 11, which is more labor-saving and improves the user experience of the switch tooling.

[0046] like Figure 2 As shown, to improve the portability of the switching fixture, the positioning element 21 can optionally be disc-shaped, with the operating component 1 connected to the center of the positioning element 21. This configuration optimizes the space occupied by the positioning element 21. Furthermore, the disc-shaped positioning element 21 better fits the shape of the valve handwheel 100, thereby improving the adaptability of the switching fixture to a certain extent. The disc-shaped positioning element 21 has a smooth outer surface, making it less likely to interfere with other components inside the well, thus reducing the difficulty of operation for the operator.

[0047] For example, the positioning component 21 is made of 304 stainless steel with a diameter of 100mm-300mm and a thickness of 4mm-8mm. This design can improve the structural strength of the positioning component 21 while ensuring its portability, thereby enhancing the reliability of the switch tooling.

[0048] Of course, the size, thickness and material of positioning component 2 can also be other models. You can choose according to the working environment as needed, and there are no restrictions here.

[0049] Optionally, the positioning hole 211 has an internal thread on its wall, and the positioning rod 22 has an external thread on its outer peripheral wall, with the positioning rod 22 and the positioning hole 211 threadedly engaged. This design not only improves the positioning stability of the positioning rod 22, but also allows adjustment of the length of the positioning rod 22 protruding from the positioning hole 211, thereby enabling the adjustment of the contact depth of the positioning rod 22 as needed according to the size of the valve handwheel 100, and improving the adaptability of the switching fixture.

[0050] In other embodiments, the positioning assembly 2 also includes a nut. The outer peripheral wall of the positioning rod 22 has external threads, while the wall of the positioning hole 211 does not have internal threads. After the positioning rod 22 passes through the positioning hole 211, it engages with the nut through a thread. When it is necessary to adjust the length of the positioning rod 22 protruding from the positioning hole 211, threaded rods of different lengths can be selected. This setting also allows for adjustment of the contact depth of the positioning rod 22 as needed, improving the adaptability of the switch tooling. It can be selected as needed according to actual requirements.

[0051] Optionally, the positioning holes 211 are all elongated holes, and the positioning holes 211 extend along the diameter direction of the positioning member 21. This setting can change the position of the positioning rod 22 in the positioning hole 211 according to the size of the valve handwheel 100, ensuring that the side wall of the positioning rod 22 abuts against the exposed bar of the valve handwheel 100, improving the adaptability of the switching fixture, and allowing the positioning rod 22 to be located as far as possible on the outer periphery of the valve handwheel 100, thereby improving the effort-saving effect and enhancing the user experience.

[0052] To improve ease of operation, the multiple positioning holes 211 may optionally be located on the same circumference. This arrangement facilitates the installation of the positioning rod 22, improves assembly efficiency, and thus enhances the ease of operation of the switch tooling.

[0053] Optionally, three positioning rods 22 are provided, and the center of the positioning element 21 is located within the triangle formed by the three positioning rods 22. Understandably, the three positioning rods 22 can abut against the exposed bars of the three valve handwheels 100, and the force application points can form a triangle, thereby ensuring the pushing strength and reducing the number of positioning rods 22, thus improving the portability of the switch tooling.

[0054] like Figures 3-4As shown, exemplarily, the number of positioning holes 211 is 5, namely a first positioning hole, a second positioning hole, a third positioning hole, a fourth positioning hole, and a fifth positioning hole. The lines connecting the first positioning hole, the second positioning hole, and the third positioning hole to the center of the positioning member 21 form a 120° angle between adjacent lines; the line connecting the first positioning hole to the center of the positioning member 21 and the line connecting the fourth positioning hole to the center of the positioning member 21 form a 144° angle; the line connecting the first positioning hole to the center of the positioning member 21 and the line connecting the fifth positioning hole to the center of the positioning member 21 form a 72° angle.

[0055] Understandably, when positioning rods 22 are provided in the first, second, and third positioning holes, the side walls of the three positioning rods 22 can respectively abut against the three protruding bars of the three-spoke valve handwheel 100; when positioning rods 22 are provided in the first, second, third, fourth, and fifth positioning holes, the side walls of the five positioning rods 22 can respectively abut against the five protruding bars of the five-spoke valve handwheel 100; when positioning rods 22 are provided in the first, fourth, and fifth positioning holes, the side walls of the three positioning rods 22 can respectively abut against three of the protruding bars of the five-spoke valve handwheel 100.

[0056] Of course, in other embodiments, the number of positioning holes 211 is not limited to this. As long as it can be ensured that the positioning rod 22 can be inserted into several positioning holes 211 and the side wall of the positioning rod 22 can abut against the exposed bar on the valve handwheel 100, no further restrictions are imposed here.

[0057] The following uses a three-spoke valve handwheel 100 and a five-spoke valve handwheel 100 as examples to illustrate the working process of the switch tooling in this embodiment:

[0058] First, observe and determine whether the valve handwheel 100 is a three-spoke or five-spoke type. If it is a three-spoke type, then install positioning rods 22 in the first, second, and third positioning holes. If it is a five-spoke type, then install positioning rods 22 in the first, second, third, fourth, and fifth positioning holes, or simply install positioning rods 22 in the first, fourth, and fifth positioning holes.

[0059] Hold the grip 11, extend the positioning assembly 2 down into the well and face the valve handwheel 100, so that each positioning rod 22 is inserted into the gap between the exposed bars of the valve handwheel 100, and then screw the grip 11 so that the side wall of the positioning rod 22 abuts against the exposed bars of the valve handwheel 100.

[0060] Continue to rotate the grip 11, causing the positioning rod 22 to push the valve handwheel 100 to move, causing the valve handwheel 100 to rotate, thereby opening or closing the valve and completing the opening and closing operation.

[0061] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
