Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical equipment and pipeline maintenance, in particular to a multifunctional maintenance tool. Background Art
[0002] The special wrench for opening and closing valves in chemical plants is a copper explosion-proof F wrench. Due to the different sizes of valve handles, there are many types of F wrenches. Each inspection or on-site operation requires carrying multiple sizes of F wrenches, which is extremely inconvenient to carry, especially for high-point inspections. If you don't carry the F wrench when you encounter a valve that needs to be opened and closed, you need to go back to the tool room to get the F wrench, which wastes operation time. In the event of an emergency shutdown, delaying the opening and closing of the valve may pose certain safety hazards. Utility Model Content

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0029] See also Figure 1 , shows a multifunctional maintenance tool, which includes a rod body 100, a first F wrench 200, a second F wrench 300, and a threaded joint 400; the rod body 100 has a first end 110 and a second end 120 that are far away from each other; the first F wrench 200 is fixed to the rod body 100 near the first end 110, and the first F wrench 200 includes two parallel first connecting rods 210a and 210b with a spacing of D1; the second F wrench 300 is fixed to the rod body 100 near the first end 110, and the second F wrench 300 includes two parallel second connecting rods 310a and 310b with a spacing of D2, and D1 is greater than D2; the threaded joint 400 is detachably connected to the second end 120, and the threaded joint 400 is used to remove the shower pipe cap.
[0030] The above-mentioned multifunctional maintenance tool is provided with a first F wrench 200 and a second F wrench 300. The first F wrench 200 is larger in size, and the second F wrench 300 is smaller in size. According to the size of the valve on site, the first F wrench 200 or the second F wrench 300 is selected for disassembly and maintenance, so that the large and small F wrenches are combined, and a threaded joint 400 with a detachable pipe cap is added at the tail. Carrying this tool during the inspection can cope with most usage scenarios. The utility model can solve the disadvantage that the operator carries multiple F wrenches for inspection, thereby improving the operating efficiency.
[0031] See also Figure 4 In one embodiment, the threaded joint 400 is threadedly connected to the second end 120 of the rod body 100, and the threaded joint 400 includes two rod-shaped structures parallel to each other, and the rod-shaped structure is a square rod-shaped structure 420. The square rod-shaped structure 420 can engage the hexagonal shower pipe cap. This state is suitable for disassembly conditions with a large space. The rod body 100 can be laid flat and engaged with the hexagonal shower pipe cap, and then rotated for disassembly, which is more time-saving and labor-saving.
[0032] See also Figure 5 In another embodiment, the threaded joint 400 is threadedly connected to the second end 120 of the rod body 100, and the threaded joint 400 includes two rod-shaped structures parallel to each other, and the two rod-shaped structures are oppositely arranged as a serrated rod body 430. When the pipe cap is a circular columnar structure, the pipe cap is removed by friction using the serrations of the serrated rod body 430, and the serrations are similar to the serrations of a pipe wrench.
[0033] See also Figure 1 In another embodiment, the threaded joint 400 is threadedly connected to the second end of the rod body 100, and the threaded joint 400 is a cap-shaped structure, and the inner side of the cap-shaped structure is a hexagonal blind hole 410 that cooperates with the shower pipe cap. The hexagonal blind hole 410 can be sleeved on the shower pipe cap for disassembly. It should be noted that, especially when the shower pipe cap is in a relatively cramped pipe bundle, the hexagonal blind hole 410 at the end of the rod body 100 can be inserted into the narrow space that needs to be repaired, and a rotational force can be applied to the wrench at the other end to transmit torque, which is more convenient and has a wider range of applicable scenarios.
[0034] In one embodiment, the first F wrench 200 and the second F wrench 300 are located in the same plane.
[0035] In one embodiment, the axis of the first connecting rod 210a relatively far away from the second end 120 is collinear with the axis of the second connecting rod 310a relatively far away from the second end 120, and the first connecting rod 210a and the second connecting rod 310a with the collinear axes form a force-applying rod-shaped portion to transmit torque to the second end 120.
[0036] In one embodiment, the first connecting rod 210 a relatively far away from the second end 120 and the second connecting rod 310 a relatively far away from the second end 120 are both flush with the end surface of the first end 110 .
[0037] In one embodiment, the first connecting rod 210 b relatively close to the second end 120 and the second connecting rod 310 b relatively close to the second end 120 are respectively detachably connected to the rod body 100 .
[0038] See also Figure 2 and Figure 3 In one embodiment, the second connecting rods 310a and 310b are detachably connected to the rod body 100, and the rod body 100 is hollow and has a receiving chamber 130, and the receiving chamber 130 is used to accommodate the disassembled second connecting rods 310a and 310b. In coordination therewith, a plug 140 is installed at the opening of the receiving chamber 130 of the rod body 100 to prevent the second connecting rods 310a and 310b installed in the receiving chamber 130 from slipping out therefrom. With such a configuration, in the face of a place with a cramped maintenance space, the second connecting rods 310a and 310b can be disassembled and installed in the hollow receiving chamber 130 of the rod body 100, so as to facilitate valve maintenance in a narrow place. When necessary, the second connecting rods 310a and 310b can be taken out and reinstalled on the rod body 100. In the specific configuration, the detachable connection method includes but is not limited to threaded connection.
[0039] Preferably, see Figure 1 In one embodiment, the length of the first connecting rods 210a and 210b is 8 cm and the diameter is 2 cm. In one embodiment, the length of the second connecting rods 310a and 310b is 5 cm and the diameter is 1 cm. In one embodiment, the length of the rod body 100 is 50 cm and the diameter is 2 cm. The first F wrench 200 of the multifunctional maintenance tool can be used to disassemble and repair valves above DN50, and the second F wrench 300 can be used to disassemble and repair valves below DN50.
[0040] In one embodiment, the threaded connector 400 is threadedly connected to the second end 120 .
