Description

Technical Field

[0001] The present application relates to the technical field of hydraulic system pipelines, and in particular to a modular pipeline conversion joint. Background Art

[0002] In the hydraulic system, some mechanisms rotate slightly, but in order to ensure the normal operation of the hydraulic system pipeline, a hose is used to overcome the pipeline changes during the rotation of the structure. The hose is stretched while rotating outward, and when it is retracted, the hose is bent at a certain angle. The hose has a certain service life. Long-term use under bending force will greatly reduce the service life of the hose, causing the hose to rupture and causing the hydraulic system to not work properly.

[0003] In order to avoid damage caused by long-term bending and stress of the hose in the rotating structure, many hydraulic systems use a center swivel joint installed at the center of rotation to avoid hose bending. However, the radial dimension of the center swivel joint is large and the weight is heavy. If a standard single-channel swivel joint is used, it can only solve the problem of one pipeline.

[0004] In order to solve the installation problem of multi-channel rotating pipelines, a multi-channel, small-volume joint is needed. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing hose connection technology and provide a modular pipeline conversion joint that can be modularly quickly connected and reliably positioned. The joint is directly installed at a rotating hinge, the rotation center of the joint is coaxial with the rotation center of the hinge, and the oil inlet and outlet of the joint are connected by hard pipes, thereby improving the reliability and safety of the pipeline.

[0011] The set screw 5 is used to prevent the plug 6 from loosening;

[0012] The plug 6 is installed at one end of the fixed joint body 1 and is used for sealing the fixed joint body.

[0013] In some embodiments, the fixed joint body 1 and the rotating joint body 2 are both hexagonal structures, and one side of the hexagonal structure is provided with an internal threaded oil hole for connecting to the pipeline of an external hydraulic system.

[0015] In some embodiments, the sealing ring 3 is in the form of a combined sealing ring.

[0016] In some embodiments, the set screw 5 is used to prevent the plug 6 from loosening.

[0017] In some embodiments, by removing the oil port plug 6 of one modular connector and connecting another modular connector to the threaded hole at the right end, a dual-channel conversion connector can be formed after tightening, and so on, a multi-channel conversion connector can be formed.

The present invention installs the conversion joint to the structural rotation axis, so that the pipeline always rotates around the central axis of the structural member during movement, and the length of the pipeline always remains unchanged.

[0040] The embodiment of the present invention provides a modular pipeline conversion joint, such as Figure 1 As shown, it includes: a fixed joint body 1, a rotating joint body 2, a sealing ring 3, a retaining ring 4, a set screw 5 and a plug 6.

[0049] In some embodiments, the combined sealing ring 3 is in the form of a combined sealing ring.

[0050] In some embodiments, the set screw 5 is used to prevent the plug 6 from loosening.

[0051] In some embodiments, by removing the oil port plug 6 of one modular connector and connecting another modular connector to the threaded hole at the right end, a dual-channel conversion connector can be formed after tightening, and so on, a multi-channel conversion connector can be formed.

[0052] The modular conversion joint of the embodiment of the present application is composed of a fixed joint body 1, a rotating joint body 2, a sealing ring 3, a retaining ring 4, a set screw 5 and a plug 6.

[0053] like Figure 2 and Figure 3 As shown, both the fixed joint body 1 and the rotary joint body 2 are hexagonal structures, and one side of the hexagon is provided with an internal threaded oil hole for connecting the pipeline of the external hydraulic system. The fixed joint body 1 is fixed by screwing into the hinged center axis, and the fixed joint body 1 is stationary relative to the base; the rotary joint body 2 is sealed by sealing rings 3 on the left and right sides, and oil channels are machined in the fixed joint body 1 and the rotary joint body 2. An oil port plug 6 is provided on the right side of the fixed joint body 1 to prevent leakage of oil and limit the rotary joint body 2 at the same time.

[0054] When forming a multi-channel conversion joint, it is necessary to remove the oil port 6 plug of one modular joint, and connect the other modular joint to the threaded hole at the right end of the fixed joint body 1. After tightening, a dual-channel conversion joint can be formed. Similarly, a multi-channel conversion joint can be formed.

[0055] An embodiment of the present invention provides a method for using any of the above-mentioned modular conversion joints, the method comprising:

[0056] Step 1, remove the oil port plug 6 of the modular joint.

[0057] Step 2: Connect another modular connector to the threaded hole on the right end of the connector without the plug.

[0058] Step 3: Tighten to form a dual-channel conversion joint. Figure 4 shown.

[0059] In some embodiments, the above method further comprises:

[0060] Step 4, repeat steps 1 to 3, and so on, to form a multi-channel conversion joint, the effect is as follows Figure 5 shown.

[0061] Figures 6 to 9 A diagram of the operating steps of a method for using a modular conversion joint according to any of the above embodiments of the present invention.

[0062] The initial position of the single channel module of the present invention is as follows Figure 6 As shown, the oil inlet and outlet are on the same side.

[0067] The present invention solves the problem of hose replacement during the rotation of a mechanized bridge. In the traditional hydraulic pipeline, during the rotation of the structural parts, the length of the pipeline will change as the joint connection point changes with the posture, so a hose pipeline is used to adapt to the demand for variable length; after adopting the modular conversion joint, the rotation of the pipeline is based on the center line of the conversion joint. During the rotation, the length of the pipeline is relatively fixed, so a hard pipe connection can be used directly. The conversion joint is a multi-channel, small-volume joint suitable for use in a rotation environment within a single circle.

[0068] The use of the modular adapter joint can make the layout of the pipeline more concise and reliable.

[0069] The technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.
