Technical Field

[0001] This invention relates to the field of cross-bridge docking technology, and specifically to a hinged docking device and method. Background Technology

[0002] With the rapid development of ultra-high voltage (UHV) power transmission construction, the construction of new power lines increasingly involves crossing existing power lines, high-speed railways, and highways. Currently, crossing frames serve as the primary construction equipment and safety measure for crossing projects, ensuring their safe and efficient implementation.

[0003] Existing docking devices for cross-passage structures typically include push-type and telescopic types. These devices consist of interlocking connectors and receiving components, which are fixedly installed at the ends of the netting arms on both sides of the cross-passage structure. During the docking process, the docking posture of the netting arms on both sides needs to be adjusted multiple times to ensure the connectors align with the receiving components, thereby achieving the docking of the netting arms on both sides of the cross-passage structure.

[0004] However, during the docking process of the aforementioned docking device, the adjustment accuracy requirements for the large arms of the cross-frame sealing net on both sides are relatively high, making the docking difficult and inefficient. Summary of the Invention

[0006] The receiving component (2) is a cylindrical structure with a conical recessed connector (20) at one end of the cylindrical structure. At the apex of the conical structure, there is a snap-fit ​​structure that matches the structure of the convex connector (12). The receiving component (2) is fixed to another sealing net arm through the other end of the cylindrical structure.

[0007] When connecting the two sealing arms, the convex connector (12) of the plug assembly (1) is inserted into the concave connector (20), and under the guidance of the conical surface, it enters the snap-fit ​​structure. The snap-fit ​​structure snaps the convex connector (12) to realize the docking of the two sealing arms.

[0012] Preferably, the connecting rod of the convex-button joint (12) is a cylindrical rod (120), and the convex part of the convex-button joint (12) is a spherical plug (122);

[0015] The structure of the convex joint (12) cooperating with the spherical protrusion is an arc plate (121), which is located between the base (10) and the spherical cover (11).

[0016] Preferably, the spherical cover (11) has a sleeve hole (111) and the sleeve hole (111) is provided with an elastic sleeve (13);

[0017] The convex joint (12) is horizontally inserted into the elastic sleeve (13).

[0018] Preferably, the conical bottom of the concave connector (20) is provided with a cylindrical positioning hole (201), the diameter of which is the same as the diameter of the conical bottom and slightly larger than the maximum cross-sectional diameter of the spherical cover (11);

[0019] When connecting the two sealing arms, the spherical cover (11) is inserted into the positioning hole (201).

[0020] Based on the same inventive concept, the present invention also provides a hinged docking method, comprising:

[0021] The plug-in assembly (1) fixed to the sealing arm via the base (10) is pushed toward the receiving part (2) fixed to another sealing arm;

[0024] Preferably, after the continued pushing of the plug assembly (1) causes the convex connector (12) of the plug assembly (1) rotatably connected to the base (10) to enter the conical recess of the concave connector (20) on the receiving member (2), and before the convex portion of the convex connector (12) enters the snap-fit ​​structure at the apex of the conical shape under the guidance of the conical surface, the method further includes:

[0025] Insert the spherical cap (11) on the plug assembly (1) into the positioning hole (201) at the conical bottom of the concave connector (20).

[0026] Compared with the closest existing technology, the present invention has the following beneficial effects:

[0035] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figure 1 As shown, the present invention provides a hinged docking device, including a plug-in component 1 and a receiving component 2 arranged opposite to each other. The plug-in component 1 is plugged into the receiving component 2 to realize the docking of the docking device.

[0038] like Figure 1 and Figure 2 As shown, the plug-in assembly 1 includes a base 10 and a male-female connector 12. The base 10 is spherical, also known as a spherical base 10. A flange is integrally formed along the left side of the spherical base 10 for fixing the spherical base 10 to the sealing arm. The hollow interior of the spherical base 10 effectively reduces its weight and material consumption. The right side surface of the spherical base 10 is a spherical curved surface for hinged installation of the male-female connector 12.

[0039] The convex-button joint 12 includes a cylindrical rod 120. One end of the rod 120 is formed with an arc-shaped plate 121. The surface curvature of the arc-shaped plate 121 is adapted to the spherical curved surface of the spherical base 10, ensuring that the arc-shaped plate 121 and the spherical curved surface are completely fitted and can rotate relative to each other. The other end of the rod 120 is formed with a plug joint 122. The plug joint 122 is spherical and is used for plugging the assembly 1 and the receiving part 2. The diameter of the plug joint 122 is larger than the diameter of the circular cross-section of the rod 120. The convex-button joint 12 can rotate along the spherical curved surface of the spherical base 10. Its rotation has three degrees of freedom and can be rotated according to the docking requirements, thereby realizing the adjustment of the docking posture.

[0040] A spherical cover 11 is provided on the spherical base 10. A flange is formed around the left side of the spherical cover 11. Multiple through holes 111 are provided on the flange. Bolts 14 are installed through the through holes 111 and are threadedly connected to the spherical base 10, thereby connecting the spherical cover 11 and the spherical base 10. An arc-shaped plate 121 is located between the spherical base 10 and the spherical cover 11. The surface of the arc-shaped plate 121 facing away from the spherical base 10 is completely in contact with the surface of the spherical cover 11, restricting the horizontal displacement of the arc-shaped plate 121, thereby realizing the hinged installation of the convex butt joint 12 and the spherical base 10.

[0041] A spherical cap 11 has a sleeve hole 110 along its horizontal axis, and an annular groove is formed on the inner wall of the sleeve hole 110. An elastic sleeve 13, made of rubber, is mounted on the sleeve hole 110, providing elastic recovery. A raised edge is formed around the circumference of the elastic sleeve 13, which fits into the annular groove. The raised edge of the elastic sleeve 13 engages within the annular groove of the sleeve hole 110, thus enabling the installation of the elastic sleeve 13. One end of the convex connector 12, equipped with a plug 122, extends out of the spherical cap 11, and a rod 120 passes horizontally through and connects to the elastic sleeve 13. Before docking, the elastic sleeve 13 provides support for the convex connector 12, maintaining its horizontal position. During docking, the elastic sleeve 13 is compressed to adjust the posture of the convex connector 12; upon disengagement, the compressed elastic sleeve 13 recovers, restoring the convex connector 12 to its initial horizontal state.

[0042] like Figure 1 and Figure 3 As shown, the receiving component 2 is a cylindrical structure. One end of the cylindrical structure is fixed to another sealing mesh arm, and the other end includes a concave connector 20. The concave connector 20 is cylindrical in shape, with a cavity on its left side. The cavity includes, from left to right, a positioning hole 201, a guide groove 202, and a positioning groove 203. The guide groove 202 is a conical recess that serves as a guide, and the positioning groove 203 is a snap-fit ​​structure. The positioning hole 201 has the same diameter at all points. During docking, the spherical cap 11 is inserted into the positioning hole 201, restricting the relative rotation of the concave connector 20 and the spherical cap 11, thereby achieving the overlap of the concave connector 20 and the spherical cap 11.

[0043] The opening of the guide groove 202 connects to the positioning hole 201. The guide groove 202 is tapered, and the opening diameter of the guide groove 202 is the same as the diameter of the positioning hole 201. The diameter of the guide groove 202 gradually decreases from the opening to the bottom, meaning that the inner wall of the guide groove 202 slopes from the opening to the bottom. The positioning groove 203 is located at the bottom of the guide groove 202 and communicates with it. The positioning groove 203 is spherical and is adapted to fit the spherical connector 122.

[0044] When connecting the two sealing arms, the convex connector 12 extends into the cavity of the concave connector 20. The spherical plug 122 located at the end of the convex connector 12 slides along the conical inner wall of the guide groove 202. Finally, the plug 122 is inserted into the positioning groove 203. The conical guide groove 202 plays a guiding role while reducing the contact resistance during the docking process, which is conducive to the insertion of the convex connector 12. The plug 122 is inserted into the positioning groove 203 to prevent the docking device from disengaging when subjected to impact and vibration.

[0045] The implementation principle of this embodiment is as follows: the convex butt joint 12 can rotate along the spherical curved surface of the spherical base 10. Its rotation has three degrees of freedom and can rotate according to the docking requirements, thereby realizing the adjustment of the docking posture; the conical guide groove 202 plays a guiding role while reducing the contact resistance during the docking process, which is conducive to the insertion of the convex butt joint 12.

[0046] Example 2:

[0047] like Figure 4 As shown, this invention provides a truss system, comprising two frame bodies 3 arranged opposite each other on both sides, a netting arm 4, a drive device 5 fixedly installed on the frame bodies 3, and a hinged docking device provided in Embodiment 1. The netting arms 4 on both sides are slidably connected to the frame bodies 3, and the netting arms 3 are connected to the drive device 5, which drives the netting arms 4 to slide left and right on the frame bodies 3. Multiple rigid netting supports 6 are connected to the bottom of the netting arms 4, providing a protective function.

[0048] like Figure 5 As shown, the plug-in assembly 1 and the receiving part 2 are fixedly connected to the two sides of the sealing net arm 4. The sealing net arm 4 slides relative to each other, so that the plug-in assembly 1 and the receiving part 2 complete the docking action, realizing the docking of the two sides of the frame 3. The hinged docking device improves the fault tolerance rate during docking, reduces the posture accuracy requirements of the sealing net arm 4 during docking, and reduces the posture adjustment work of the sealing net arm 4.

[0049] When the docking device is dismantled, the plug-in component 1 and the receiving component 2 slide in opposite directions as the sealing net arm 4 retracts, and the plug-in component 1 and the receiving component 2 separate. They can be reused after the crossing frame is dismantled. The system reset is quick and convenient, reducing the cost of use.

[0050] The implementation principle of this embodiment is as follows: When the devices are docked, the sealing arm 4 slides relative to each other. One end of the convex connector 12 with the plug 122 enters the positioning groove 203 along the guide groove 202 in the concave connector 20. The hinged convex connector 12 with three degrees of rotational freedom, together with the concave connector 20 with the guide groove 202, improves the fault tolerance rate during docking, reduces the posture accuracy requirements of the sealing arm 5 during docking, and reduces the posture adjustment work of the sealing arm 5.

[0051] Example 3:

[0052] Based on the same inventive concept, this invention also provides a hinged docking method, such as... Figure 6 As shown, it includes:

[0053] Step 1: Push the plug-in assembly 1, which is fixed to the sealing net arm via the base 10, toward the receiving part 2, which is fixed to another sealing net arm;

[0054] Step 2: Continue to push the plug-in assembly 1 so that the convex connector 12 of the plug-in assembly 1, which is rotatably connected to the base 10, enters the conical recess of the concave connector 20 on the receiving part 2.

[0055] Step 3: Under the guidance of the conical surface, the convex part of the convex joint 12 enters the snap-fit ​​structure at the apex of the cone. The snap-fit ​​structure snaps the convex joint 12 together to achieve the docking of the two sealing net arms.

[0056] Between steps 2 and 3, the following also applies:

[0057] Insert the spherical cap 11 on the plug assembly 1 into the positioning hole 201 at the conical bottom of the concave connector 20.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit its protection scope. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this application, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the application, but these changes, modifications or equivalent substitutions are all within the protection scope of the claims pending approval.
