Description

Technical Field

[0001] This utility model relates to the field of steel cage processing technology, and in particular to a power supply connector assembly and a steel cage welding equipment for tunnel segments. Background Technology

[0002] During tunnel construction, after the tunnel boring machine (TBM) excavates a circular hole, multiple arc-shaped shield segments are needed to secure the hole, providing a robust and safe space for subsequent construction. Each shield segment is formed by combining a shield segment reinforcement cage with concrete anchorage. The shield segment reinforcement cage consists of multiple arc-shaped single-layer meshes and multiple stirrups; the single-layer meshes are spaced apart and parallel to each other; the multiple stirrups are welded and fixed to the outer edges of the single-layer meshes, also spaced apart and parallel to each other.

[0003] The shield tunnel segment reinforcement cage welding equipment is used for the fabrication of the three-dimensional mesh of the shield tunnel segment reinforcement cage, which involves precisely positioning and welding the stirrups to the individual mesh pieces. This equipment is divided into four working areas: a mesh stacking area, a stirrup insertion area, a stirrup welding area, and a cage exit area. Each working area is equipped with a single-piece mesh mold positioning device for positioning the individual mesh pieces, and this device can be switched sequentially between the four working areas. The equipment is also equipped with a drive unit that drives the single-piece mesh mold positioning device to switch between the four working areas sequentially.

[0004] The positioning mechanism and detection system configured on the single-piece mesh mold positioning device must operate under power supply. However, the single-piece mesh mold positioning device switches sequentially in a specified direction (clockwise or counterclockwise) on the shield tunnel segment rebar cage welding equipment. To meet the power supply requirements, four male power supply connectors need to be installed on the fixed track of the shield tunnel segment rebar cage welding equipment to cooperate with four female power supply connectors installed on each single-piece mesh mold positioning device. After the position switching is completed, the male and female power supply connectors cooperate to complete automatic power supply.

[0005] Currently, commonly used power supply connector components of this type mainly include heavy-duty connectors. These aviation plugs require high precision in fitting and place high demands on the processing and rotational precision of the shield tunnel segment steel cage welding equipment. Otherwise, the male connector cannot fit with the female connector, affecting the overall operation of the equipment. Utility Model Content

[0006] Based on the above problems, the purpose of this utility model is to provide a power supply connector assembly and a shield tunnel segment reinforcement cage welding equipment, which can effectively prevent the power supply connector from failing to connect or being loosely connected, and reduce the processing accuracy and motion accuracy requirements of the shield tunnel segment reinforcement cage welding equipment.

[0007] To achieve the above objectives, the following technical solution is provided:

[0008] In a first aspect, this utility model provides a power supply connector assembly, comprising:

[0009] The first power supply connector includes a first fixed base, a first conductive post, and a first cable. The first fixed base is mounted on the single-piece mesh mold positioning device of the shield tunnel segment steel cage welding equipment. The first conductive post is mounted on the first fixed base, and the first cable is connected to the first conductive post.

[0010] The second power supply connector includes a second fixed base, a driving component, an insulating plate, an elastic component, a second conductive post, and a second cable. The second fixed base is disposed on the fixed track of the shield tunnel segment reinforcement cage welding equipment. The fixed end of the driving component is disposed on the second fixed base, and the output end of the driving component is connected to the insulating plate. The second conductive post is slidably disposed on the insulating plate, and the second cable is connected to the second conductive post. The elastic component is sandwiched between the insulating plate and the second conductive post. The driving component is used to drive the insulating plate to move so that the second conductive post aligns with the first conductive post and compresses the elastic component.

[0011] As an optional solution for the power supply connector assembly provided by this utility model, the first fixing base includes a first plate and a second plate connected to each other. The first plate is disposed on the single-piece mesh mold positioning device, and the first conductive post is disposed on the second plate.

[0012] As an optional solution to the power supply connector assembly provided by this utility model, the second plate is provided with a mounting hole, the first conductive post passes through the mounting hole, and an insulating sleeve is provided between the first conductive post and the mounting hole.

[0013] As an optional solution to the power supply connector assembly provided by this utility model, a first insulating pad is provided between the first conductive post and the second plate, and the first power supply connector further includes a first locking nut threaded to the first conductive post, and a second insulating pad is provided between the first locking nut and the second plate.

[0014] As an optional solution to the power supply connector assembly provided by this utility model, the insulating plate is provided with a through hole, and the second conductive post is movably inserted through the through hole.

[0015] As an optional solution to the power supply connector assembly provided by this utility model, the second power supply connector further includes a second locking nut threaded to the second conductive post, and the second locking nut is disposed on the side of the insulating plate away from the elastic member.

[0016] As an optional solution to the power supply connector assembly provided by this utility model, a gasket is provided between the second locking nut and the insulating plate.

[0017] As an optional solution to the power supply connector assembly provided by this utility model, a gasket is provided between the gasket and the insulating plate.

[0018] As an optional solution for the power supply connector assembly provided by this utility model, the insulating plate is provided with a first mounting plate, the second conductive post is provided with a second mounting plate, and the elastic element is sleeved on the second conductive post and sandwiched between the first mounting plate and the second mounting plate.

[0019] Secondly, this utility model also provides a shield tunnel segment reinforcement cage welding equipment, including a driving device, a fixed track, a single mesh mold positioning device, and the aforementioned power supply connector assembly. The driving device is used to drive the single mesh mold positioning device to switch positions on the fixed track, and the power supply connector assembly is used to supply power to the single mesh mold positioning device.

[0020] The beneficial effects of this utility model are as follows:

[0021] The power supply connector assembly and shield tunnel segment reinforcement cage welding equipment provided by this utility model achieve electrical connection between the first and second cables through the contact between the second conductive post and the first conductive post, thereby meeting the power demand of the single-piece mesh mold positioning device. When the single-piece mesh mold positioning device moves to the target position, the driving component drives the insulating plate to move, and the insulating plate drives the second conductive post to contact the first conductive post. The elastic element is compressed and deformed, which plays a pressing role in the contact between the second conductive post and the first conductive post, ensuring good contact between all the second conductive posts and the first conductive post. This can effectively prevent the power supply connector from failing to connect or from being loosely connected, improve electrical safety, reduce the processing accuracy and movement accuracy requirements of the shield tunnel segment reinforcement cage welding equipment, and ensure the normal and stable operation of the equipment.

[0040] like Figures 1 to 4 As shown, this embodiment provides a power supply connector assembly, which includes a first power supply connector 1 and a second power supply connector 2. The first power supply connector 1 includes a first fixing base 11, a first conductive post 12, and a first cable 13. The first fixing base 11 is disposed on the single-piece mesh mold positioning device 300 of the shield tunnel segment reinforcement cage welding equipment, the first conductive post 12 is disposed on the first fixing base 11, and the first cable 13 is connected to the first conductive post 12. The second power supply connector 2 includes a second fixing base 21, a driving component 22, an insulating plate 23, an elastic component 24, and a second conductive post 25. The second conductive post 25 and the second cable 26 are mounted on the fixed track 200 of the shield tunnel segment reinforcement cage welding equipment. The fixed end of the driving component 22 is mounted on the second fixed seat 21, and the output end of the driving component 22 is connected to the insulating plate 23. The second conductive post 25 is slidably mounted on the insulating plate 23, and the second cable 26 is connected to the second conductive post 25. The elastic element 24 is clamped between the insulating plate 23 and the second conductive post 25. The driving component 22 is used to drive the insulating plate 23 to move so that the second conductive post 25 aligns with the first conductive post 12 and compresses the elastic element 24. Four pairs of first power supply connectors 1 and second power supply connectors 2 can be provided to independently power the four working areas of the shield tunnel segment reinforcement cage welding equipment. Of course, different numbers of first power supply connectors 1 and second power supply connectors 2 can be used depending on the specific situation (such as the number of working areas or the number of cables).

[0041] The first cable 13 and the second cable 26 are electrically connected by the contact between the second conductive post 25 and the first conductive post 12, thereby meeting the power requirements of the single-piece mesh mold positioning device 300. When the single-piece mesh mold positioning device 300 moves to the target position, the driving component 22 drives the insulating plate 23 to move. The insulating plate 23 drives the second conductive post 25 to contact the first conductive post 12. The elastic component 24 is compressed and deformed, which plays a pressing role in the contact between the second conductive post 25 and the first conductive post 12, ensuring good contact between all the second conductive posts 25 and the first conductive post 12. This can effectively prevent the power supply connector from failing to connect or from being loosely connected, improve the safety of power supply, reduce the processing accuracy and movement accuracy requirements of the shield tunnel segment steel cage welding equipment, and ensure the normal and stable operation of the equipment.

[0042] Optionally, the first fixing base 11 includes a first plate 111 and a second plate 112 connected to each other. The first plate 111 is disposed on the single-piece mesh mold positioning device 300, and the first conductive post 12 is disposed on the second plate 112. The first plate 111 can be a horizontal plate, and the second plate 112 can be a vertical plate, which facilitates installation.

[0043] To ensure insulation between the first conductive post 12 and the second plate 112, optionally, the second plate 112 is provided with a mounting hole 113, through which the first conductive post 12 passes, and an insulating sleeve 114 is provided between the first conductive post 12 and the mounting hole 113. The insulating sleeve 114 can be made of rubber, which has good insulation performance and strong buffering capacity. Multiple mounting holes 113 and multiple first conductive posts 12 can be provided, depending on the number of first cables 13.

[0044] To further ensure the insulation between the first conductive post 12 and the second plate 112, optionally, a first insulating pad 14 is provided between the first conductive post 12 and the second plate 112. The first power supply connector 1 also includes a first locking nut 15 threaded to the first conductive post 12, and a second insulating pad 16 is provided between the first locking nut 15 and the second plate 112. Under the insulating effect of the first insulating pad 14 and the second insulating pad 16, leakage from the first conductive post 12 to the second plate 112 can be prevented, ensuring power supply safety.

[0045] To facilitate the sliding of the second conductive post 25 relative to the insulating plate 23, the insulating plate 23 may optionally have a through hole 231 through which the second conductive post 25 movably passes. A clearance fit is used between the through hole 231 and the second conductive post 25 to facilitate movement of the second conductive post 25 within the through hole 231. Multiple through holes 231 and multiple conductive posts 25 may be provided, depending on the number of second cables 26. To prevent the second conductive post 25 from detaching from the insulating plate 23, the second power supply connector 2 may optionally include a second locking nut 27 threadedly connected to the second conductive post 25, the second locking nut 27 being located on the side of the insulating plate 23 away from the elastic element 24.

[0046] To prevent the second locking nut 27 from damaging the insulating plate 23, a washer 28 may be provided between the second locking nut 27 and the insulating plate 23. The washer 28 may be made of rubber, providing strong cushioning and a long service life. Alternatively, a pad 29 may be provided between the washer 28 and the insulating plate 23. The contact area between the pad 29 and the insulating plate 23 is larger than the contact area between the washer 28 and the pad 29, further preventing damage to the insulating plate 23.

[0047] To facilitate the installation of the elastic element 24, optionally, the insulating plate 23 is provided with a first mounting plate 232, the second conductive post 25 is provided with a second mounting plate 251, and the elastic element 24 is sleeved on the second conductive post 25 and sandwiched between the first mounting plate 232 and the second mounting plate 251. Specifically, the elastic element 24 can be a spring, which has strong elastic deformation capacity and low cost. One end of the spring abuts against the first mounting plate 232, and the other end of the spring abuts against the second mounting plate 251.

[0048] This embodiment also provides a shield tunnel segment reinforcement cage welding equipment, including a drive device 100, a fixed track 200, a single mesh mold positioning device 300, and the aforementioned power supply connector assembly. The drive device 100 is used to drive the single mesh mold positioning device 300 to switch positions on the fixed track 200, and the power supply connector assembly is used to supply power to the single mesh mold positioning device 300. The first cable 13 and the second cable 26 are electrically connected by the contact between the second conductive post 25 and the first conductive post 12, thereby meeting the power requirements of the single-piece mesh mold positioning device 300. When the single-piece mesh mold positioning device 300 moves to the target position, the driving component 22 drives the insulating plate 23 to move. The insulating plate 23 drives the second conductive post 25 to contact the first conductive post 12. The elastic component 24 is compressed and deformed, which plays a pressing role in the contact between the second conductive post 25 and the first conductive post 12, ensuring good contact between all the second conductive posts 25 and the first conductive post 12. This can effectively prevent the power supply connector from failing to connect or from being loosely connected, improve the safety of power supply, reduce the processing accuracy and movement accuracy requirements of the shield tunnel segment steel cage welding equipment, and ensure the normal and stable operation of the equipment.

[0049] To meet the normal power supply requirements of the single-piece mesh mold positioning device 300, after the driving device 100 drives the single-piece mesh mold positioning device 300 to complete the position switching, the output rod of the driving component 22 extends, driving the insulating plate 23 to move forward, the second conductive post 25 contacts the first conductive post 12, the elastic component 24 is compressed and deformed, which plays a pressing role in the contact between the second conductive post 25 and the first conductive post 12, ensuring good contact between all the second conductive posts 25 and the first conductive post 12.

[0050] When the drive device 100 drives the single-piece mesh mold positioning device 300 to complete the position switching, the output rod of the drive component 22 retracts, and the first power supply connector 1 and the second power supply connector 2 of the power supply connector assembly disengage, preventing the second power supply connector 2 of the power supply connector assembly from interfering with the moving single-piece mesh mold positioning device 300. When switching positions, the single-piece mesh mold positioning device 300 does not need power.
