[0002] F wrenches and pipe clamps occupy a core position in equipment installation, process switching, inspection and maintenance, etc., especially in the production, manufacturing and installation of equipment in industries such as petroleum, petrochemicals, gas stations, chemicals, electricity, and mining. However, these tools also expose some problems during use. Specifically, the design feature of the F wrench is that its opening is composed of two fixed surfaces, and the edge of the handwheel is clamped by these two points of contact during operation. However, this design makes the contact surface between the F wrench and the handwheel not tight enough, and it is easy to slip when switching the valve, which may not only cause equipment damage, but also pose serious safety hazards, such as object impact accidents, which in turn pose a threat to the personal safety of the staff. In addition, the specifications of valves in chemical production equipment are varied, so the specifications of the F wrenches required are also correspondingly complicated. If the staff needs to carry F wrenches of various specifications with them, it will undoubtedly increase the inconvenience of work.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.
[0024] like Figure 1 and Figure 2 As shown, the multifunctional maintenance tool for chemical industry provided by the embodiment of the utility model comprises a cross bar 1, a fixed bar 3, a front sliding sleeve 4, a sliding handle 5, an anti-slip rod 6 and a locking bolt 7.
[0025] A square groove 2 is provided at the lower part of the front end of the cross bar 1. A small F wrench is formed at the front end of the cross bar 1 at the square groove 2, and the rear end of the cross bar 1 is a force-applying part.
[0026] A fixed rod 3 is provided at the upper part of the front end of the cross bar 1, a front sliding sleeve 4 is slidably installed in the middle part of the cross bar 1, a sliding handle 5 is provided at the upper part of the front sliding sleeve 4, and three anti-slip rods 6 are evenly distributed horizontally in the circumferential direction on the upper end of the sliding handle 5, and a large F wrench is formed at the fixed rod 3 and the sliding handle 5.
[0027] A locking bolt 7 is provided on the front sliding sleeve 4 , and the end of the locking bolt 7 is screwed into the threaded hole of the side wall of the front sliding sleeve 4 and then abuts against the side wall of the cross bar 1 .
[0028] It should be noted that the anti-drop rod 6 and the upper end of the sliding handle 5 are threadedly connected, so it is easy to disassemble and install the anti-drop rod 6, and thus adapt to the use situation where the anti-drop rod 6 is not needed. The staff holds the force applying part and applies force.
[0029] The small F wrench is used for valves below DN25. The front sliding sleeve 4 is slidably installed, so that the spacing between the fixed rod 3 and the sliding clamping handle 5 can be adjusted, thereby forming large F wrenches of different specifications. The large F wrench is used for valves above DN25. The adjustment fixed rod 3 and the sliding clamping handle 5 of the large F wrench clamp the valve door wheel, and the three anti-drop rods 6 can further clamp the door wheel to prevent the sliding clamping handle 5 from loosening, thereby improving the reliability of operation and making the valve switch accurate, thereby greatly improving the safety of process and process switching, reducing the labor intensity of staff, improving work efficiency, and providing better protection for continuous and stable production. The utility model provides a small F wrench and an adjustable large F wrench, so that the staff does not need to carry multiple F wrenches of different specifications, thereby reducing the burden of the staff carrying multiple wrenches. The tool has a simple structure, strong practicality, and is easy to promote and use.
[0030] In this embodiment, an adjusting screw 8 is disposed on the upper portion of the front sliding sleeve 4 , a threaded hole is disposed on the lower end of the sliding handle 5 , and the lower end of the sliding handle 5 is located at the upper end of the adjusting screw 8 .
[0031] It should be noted that the sliding clamping handle 5 is threadedly installed, so the height of the sliding clamping handle 5 can be adjusted to better adapt to valves of different specifications.
[0032] In this embodiment, the front sliding sleeve 4 is an annular structure, and the front sliding sleeve 4 is sleeved on the cross bar 1. The cross section of the cross bar 1 and the hole in the middle of the front sliding sleeve 4 are both rectangular structures.
[0033] It should be noted that the front sliding sleeve 4 and the cross bar 1 connected in a sleeve manner are a sliding structure with a simple structure, a quasi-rectangular structure, that is, a structure similar to a rectangle, and the cross section of the cross bar 1 and the hole in the middle of the front sliding sleeve 4 are rounded rectangles, thereby preventing the front sliding sleeve 4 and the cross bar 1 from rotating relative to each other.
[0034] In this embodiment, a clamp arm 9, a fixed clamp body 10, a rear sliding sleeve 11, a movable clamp body 12 and a threaded rotating wheel 13 are provided at the rear end of the cross bar 1.
[0035] The front end of the clamp arm 9 is detachably connected to the rear end of the cross bar 1, and a fixed clamp body 10 is provided on the side wall of the rear end of the clamp arm 9. A rear sliding sleeve 11 is slidably provided in the middle of the clamp arm 9, and a movable clamp body 12 is provided at the rear end of the rear sliding sleeve 11, and a clamping space is formed between the fixed clamp body 10 and the movable clamp body 12.
[0036] A threaded wheel 13 is rotatably mounted on the front end of the rear sliding sleeve 11, and an external thread is arranged on the side wall of the clamp arm 9 along its length direction, and the threaded wheel 13 is threadedly connected to the external thread.
[0037] It should be noted that the clamp arm 9, the fixed clamp body 10, the rear sliding sleeve 11, the movable clamp body 12 and the threaded rotating wheel 13 are combined to form the structure of the movable pipe clamp. The clamp arm 9 and the cross bar 1 have the same structure and are connected by threads. The sliding part of the rear sliding sleeve 11 has the same structure as the front sliding sleeve 4.
[0038] The threaded wheel 13 is rotated, and the threaded wheel 13 moves on the external thread of the side wall of the clamp arm 9, thereby moving the rear sliding sleeve 11, thereby changing the distance between the fixed clamp body 10 and the movable clamp body 12 to adapt to objects such as pipes of different sizes.
[0039] In this embodiment, a receiving hole 14 is provided at the rear end of the clamp arm 9 , and a listening rod 15 is provided in the receiving hole 14 .
[0040] It should be noted that the listening rod 15 is an ideal tool for checking machine and equipment failures, valve leakage, and water leakage in coal mines, thereby improving the practicality of the tool.
[0041] In this embodiment, the listening rod 15 includes a pickup head 16 and a guide column 17 connected to each other. The guide column 17 is inserted into the receiving hole 14 , and the pickup head 16 is close to the opening of the receiving hole 14 .
[0042] The hole wall of the receiving hole 14 close to the hole opening is provided with an internal thread, and the end side wall of the guide column 17 close to the pickup head 16 is provided with an external thread, and the guide column 17 and the receiving hole 14 are threadedly connected.
[0043] It should be noted that the guide column 17 and the receiving hole 14 are threadedly connected, so the listening bar 15 can be prevented from slipping out of the receiving hole 14 .
[0044] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
