[0031] Embodiment 1:

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 ;

[0033] The locking nut design problem in piston compressors: the original design used a locking nut with a polygonal force-bearing surface and used a fork-type wrench for locking. However, due to the limited size of the crosshead window cover, the wrench was difficult to place and easy to slip, resulting in poor locking effect and easy loosening.

[0034] Based on this, the present application provides a compressor piston rod and cross head locking cap locking tool, including:

[0035] The force-bearing part 1 includes a force arm 11 for applying force, one end of the force arm 11 is provided with a combination part 12, the inner side of the combination part 12 is provided with a sleeve part 2, and the sleeve part 2 is combined with the target area;

[0036] The sleeve portion 2 includes a body 21, a sleeve area 22 is provided in the center of the body 21, and the sleeve area 22 is adapted to the target area;

[0037] One or more force-bearing parts 1 adapted to the combination part 12 are arranged on the outer side of the main body 21, and are used to cooperate with the force arm 11 to drive the combination part 12 to drive the main body 21 to apply a force in one direction to the target area.

[0038] By providing the force-bearing part 1 and the sleeve part 2, the tool can effectively apply force to the target area, thereby achieving a stable locking of the piston rod and the cross head lock cap. The force arm 11 of the force-bearing part 1 provides a lever effect for manual force application, making the locking operation more convenient. The design of the sleeve part 2 ensures that the tool fits tightly with the target area, thereby ensuring that the applied force can be accurately transmitted to the target area, improving the accuracy and stability of the locking effect.

[0039] Through the combination of the force-bearing part 1 and the sleeve part 2, the locking force can be evenly applied to the target area, thereby effectively preventing the piston rod and the cross head lock nut from loosening and improving the locking effect.

[0040] The design of the force arm 11 of the force-bearing part 1 provides a lever effect for manual force application, making the operation more convenient and reducing the manpower consumption during the locking process.

[0041] The design of the sleeve portion 2 can adapt to target areas of different shapes and sizes, so that the locking tool has strong versatility and can be used in the locking work of compressor piston rods and crosshead lock caps of various specifications.

[0042] One or more installation areas 29 are provided inside the sleeve area 22 of the body 21, and a limit member 25 is provided at the installation area 29.

[0043] The limiting member 25 includes one or more symmetrically arranged limiting members 25 , which are adapted to the target area to force the main body 21 and the target area to be stably combined.

[0044] Both ends of the limiting member 25 are provided with protrusions 27 , and the adjusting assembly 24 is installed at the protrusions 27 .

[0045] A telescopic assembly 23 is provided on one side of the limiting member 25 close to the inner side of the sleeve area 22 of the body 21 for adjusting the distance between the limiting member 25 and the target area.

[0046] The limiting member 25 helps to stabilize the position of the tool in the target area. The limiting member 25 is symmetrically arranged and adapted to the target area, forcing the combination of the main body 21 and the target area to be more stable.

[0047] An adjusting component 24 is installed on the protrusion 27. The function of the adjusting component 24 is to adjust the position of the limiting member 25 according to actual needs to ensure that the limiting member 25 can be accurately aligned with the target area, thereby achieving a stable locking effect.

[0048] In addition, each stopper 25 is provided with a telescopic assembly 23 on one side close to the inner side of the sleeve area 22 of the body 21. These telescopic assemblies 23 are used to adjust the distance between the stopper 25 and the target area to ensure that the stopper 25 can completely fit the target area and provide a more accurate locking operation.

[0049] The telescopic assembly 23 is usually composed of a telescopic rod or a telescopic device, and is located on the side of the limiter 25 close to the inner side of the sleeve area 22 of the body 21. Its main function is to adjust the distance between the limiter 25 and the target area to ensure that the limiter 25 can completely fit the target area. By adjusting the telescopic assembly 23, the user can accurately adjust the position of the limiter 25 according to the actual situation to ensure that the tool can be firmly connected to the target area in the locked state.

[0050] Embodiment: 2:

[0051] See also Figure 5 , Figure 6 as well as Figure 7 :

[0052] Both ends of the adjustment component 24 are provided with an adjustment rod 26, the other end of the adjustment rod 26 extends to one side of the protrusion 27, and is combined with the protrusion 27. The adjustment rod 26 is generally combined with the telescopic component 23, and through the combination with the protrusion 27, such as a threaded rod or a straight rod, the threaded rod can adjust the position of the protrusion 27 on the rod body by rotating, and the support rod, in conjunction with the use of the adjustment component 24, can also adjust the position of the protrusion 27;

[0053] Sleeves 28 are provided at both ends of the limiting member 25, and an extension arm adapted to the target area is movably connected to the inner side of the sleeve 28.

[0054] In this embodiment, the stopper 25 is arranged in an "L" or "I" shape. When it is in an "L" shape, its long arm is combined with the telescopic assembly 23, and the short arm can be adjusted to the overall length by the sleeve 28, so that the polygons of different lengths can be adapted for fixing;

[0055] When it forms an "I" shape, one side of it can be in contact with one side of the polygon;

[0056] Embodiment 3:

[0057] See also Figure 1 and Figure 2 ;

[0058] A locking member 13 is provided at the top of the combining portion 12 , and the locking member 13 and the combining portion 12 are adapted to form a closed area for combining with the target area.

[0059] The locking member 13 is generally located at the top of the combination part 12, and is adapted to form a closed area with the combination part 12. Its main function is to ensure that the connection between the combination part 12 and the target area is firm and reliable in the locked state. The locking member 13 usually uses a thread, a bayonet, a clamping method, etc. to tightly fix the combination part 12 on the target area, thereby achieving a stable locking of the target area.

[0060] In this embodiment, the combination part 12 has two forms.

[0061] The first type: there is only one combination unit 12, see Figure 1 At this time, both ends of the combined part 12 extend upward, and holes are opened on both sides. The combination of the locking member 13 and the holes realizes the closure of the combined part 12;

[0062] The second type: there are two combination parts 12, see Figure 2 At this time, the two combination parts 12 are combined, and the inner sides are provided with meshing grooves adapted to the outer side of the body 21. Both ends of the combination of the two combination parts 12 extend outward for a section, and are fixed to the outer side of the body 21 by the above-mentioned locking member 13. The force in one direction can be applied by the force arm 11 to realize rotation;

[0063] Embodiment 4:

[0064] See also Figure 5 , Figure 6 as well as Figure 7 :

[0065] One end of the adjusting rod 26 is combined with the protrusion 27, and the other end extends to one side of the protrusion 27. This design enables the adjusting rod 26 to be connected to the protrusion 27, thereby realizing the adjustment of the position of the limiting member 25. By rotating or moving the adjusting rod 26, the position of the limiting member 25 can be flexibly adjusted to ensure that it is accurately aligned with the target area, further enhancing the stability and adaptability of the locking tool.

[0066] At the same time, sleeves 28 are provided at both ends of the stopper 25, and an extension arm adapted to the target area is connected to the inner side of the sleeve 28. This arrangement can ensure a tight connection between the stopper 25 and the target area, and at the same time, through the effect of the extension arm, the stability and fit between the stopper 25 and the target area can be further enhanced, thereby improving the accuracy and reliability of the locking effect.

[0067] In addition, a locking member 13 is provided at the top of the combination part 12, and the locking member 13 and the combination part 12 are adapted to form a closed area for combination with the target area. The design of the locking member 13 ensures that in the locked state, the connection between the combination part 12 and the target area is more firm and stable, preventing the locking tool from loosening or shifting during use, thereby improving the reliability and safety of the entire locking system.

[0068] Through the design of the adjustment component 24 and the locking member 13, the locking tool can be more accurately aligned with the target area and maintain a stable connection in the locked state, effectively preventing loosening or displacement and improving the stability and reliability of the tool.

[0069] The design of the adjustment assembly 24 and the sleeve 28 enables the position of the limiter 25 to be adjusted flexibly and to be closely connected with the target area, which is more adaptable. At the same time, the design of the locking member 13 simplifies the locking operation and improves the convenience and efficiency of the operation.

[0070] In this embodiment, the position of the protrusion 27 can be at one end of the limiting member 25 or at the top of one end of the limiting member 25, corresponding to different states in Embodiment 2, so as to be able to adapt to different polygons.

[0071] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
