Description

Technical Field

[0001] The invention relates to the technical field of steel cage processing, and in particular to a power supply device and shield segment steel cage welding equipment. Background Art

[0002] During the tunnel construction process, after the shield machine digs a circular hole, multiple arc-shaped shield segments are needed to fix the circular hole to provide a solid and safe space for subsequent projects. The shield segment is composed of a shield segment steel cage and concrete anchors. The shield segment steel cage includes multiple arc-shaped single-piece nets and multiple stirrups; multiple single-piece nets are spaced and arranged parallel to each other; multiple stirrups are welded and fixed on the outer edges of multiple single-piece nets at intervals and parallel to each other.

[0003] The shield segment steel cage welding equipment is used to make the three-dimensional mesh of the shield segment steel cage, that is, to accurately position the stirrups and the single-piece mesh and weld them. In this shield segment steel cage welding equipment, there are 4 working areas: mesh stacking area, stirrup insertion area, stirrup welding area and cage exit area. A single-piece mesh mold positioning device is set in each working area to position the single-piece mesh, and the single-piece mesh mold positioning device can be switched sequentially in the 4 working areas. The shield segment steel cage welding equipment is equipped with a driving device to drive the single-piece mesh mold positioning device to switch sequentially in the 4 working areas.

[0004] The positioning mechanism and detection system configured on the single-piece mesh mold positioning device must work when powered on, but the single-piece mesh mold positioning device has been switching sequentially in the specified direction (clockwise or counterclockwise) on the shield segment reinforcement cage welding equipment. In order to meet the power supply requirements, 4 power supply male heads need to be set on the fixed track of the shield segment reinforcement cage welding equipment, and cooperate with the 4 power supply female heads set on each single-piece mesh mold positioning device. After the position switching is completed, the power supply male head cooperates with the power supply female head to complete automatic power supply.

[0005] At present, the commonly used power supply devices of this type are mainly in the form of heavy-load connectors. This type of aviation plug has high matching accuracy and requires high processing accuracy and rotation accuracy of the shield segment steel cage welding equipment. Otherwise, the male head cannot match the female head, affecting the overall operation of the equipment. Summary of the invention

[0006] Based on the above problems, the purpose of the present invention is to provide a power supply device and a shield segment steel cage welding equipment, which can effectively prevent the power supply joints from not being connected or being poorly connected, and reduce the processing accuracy and movement accuracy requirements of the shield segment steel cage welding equipment.

[0007] In order to achieve the above objectives, the following technical solutions are provided:

[0040] like Figures 1 to 4 As shown, this embodiment provides a power supply device, 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 seat 11, a first conductive column 12 and a first cable 13. The first fixing seat 11 is arranged on a single-piece mesh mold positioning device 300 of a shield segment steel cage welding device. The first conductive column 12 is arranged on the first fixing seat 11, and the first cable 13 is connected to the first conductive column 12; the second power supply connector 2 includes a second fixing seat 21, a driving member 22, an insulating plate 23, an elastic member 24, and a second conductive column 2 5 and the second cable 26, the second fixed seat 21 is arranged on the fixed track 200 of the shield segment steel cage welding equipment, the fixed end of the driving member 22 is arranged on the second fixed seat 21, the output end of the driving member 22 is connected to the insulating plate 23, the second conductive column 25 is slidably arranged on the insulating plate 23, the second cable 26 is connected to the second conductive column 25, the elastic member 24 is clamped between the insulating plate 23 and the second conductive column 25, and the driving member 22 is used to drive the insulating plate 23 to move so that the second conductive column 25 is docked with the first conductive column 12 and compresses the elastic member 24. The first power supply connector 1 and the second power supply connector 2 can be provided with four pairs to independently power the four working areas of the shield segment steel cage welding equipment. Of course, different pairs of first power supply connectors 1 and second power supply connectors 2 can also be used according to specific circumstances (such as the number of working areas or the number of cables).

[0041] The electrical connection between the first cable 13 and the second cable 26 is achieved by the docking of the second conductive column 25 and the first conductive column 12, thereby meeting the power demand 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 member 22 drives the insulating plate 23 to move, and the insulating plate 23 drives the second conductive column 25 to contact the first conductive column 12. The elastic member 24 is compressed and deformed, which has a pressing effect on the contact between the second conductive column 25 and the first conductive column 12, ensuring that all the second conductive columns 25 are in good contact with the first conductive column 12, which can effectively prevent the power supply connector from not being able to dock or being poorly connected, thereby improving the safety of electricity use, reducing the processing accuracy and movement accuracy requirements of the shield segment steel cage welding equipment, and ensuring the normal and stable operation of the equipment.

[0042] Optionally, the first fixing seat 11 includes a first plate 111 and a second plate 112 connected to each other, the first plate 111 is arranged on the single-sheet mesh mold positioning device 300, and the first conductive column 12 is arranged on the second plate 112. The first plate 111 may be a horizontal plate, and the second plate 112 may be a vertical plate for easy installation.

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

[0044] To further ensure the insulation between the first conductive column 12 and the second plate 112, optionally, a first insulating pad 14 is provided between the first conductive column 12 and the second plate 112, and the first power supply connector 1 further includes a first locking nut 15 threadedly connected to the first conductive column 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, the first conductive column 12 can be prevented from leaking to the second plate 112, thereby ensuring power supply safety.

[0045] To facilitate the sliding of the second conductive column 25 relative to the insulating plate 23, the insulating plate 23 is optionally provided with a through hole 231, and the second conductive column 25 is movably arranged in the through hole 231. A clearance fit is adopted between the through hole 231 and the second conductive column 25, so that the second conductive column 25 can move in the through hole 231. Multiple through holes 231 and second conductive columns 25 can be provided, depending on the number of second cables 26. To prevent the second conductive column 25 from being separated from the insulating plate 23, the second power supply connector 2 also includes a second locking nut 27 threadedly connected to the second conductive column 25, and the second locking nut 27 is arranged on a side of the insulating plate 23 away from the elastic member 24.

[0046] To prevent the second locking nut 27 from damaging the insulating plate 23, a gasket 28 is optionally provided between the second locking nut 27 and the insulating plate 23. The gasket 28 can be made of rubber material, which has strong buffering ability and long service life. Optionally, a pad 29 is provided between the gasket 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 gasket 28 and the pad 29, further preventing damage to the insulating plate 23.

[0047] To facilitate the installation of the elastic member 24, optionally, the insulating plate 23 is provided with a first mounting plate 232, the second conductive column 25 is provided with a second mounting plate 251, and the elastic member 24 is sleeved on the second conductive column 25 and sandwiched between the first mounting plate 232 and the second mounting plate 251. The elastic member 24 can be a spring with strong elastic deformation ability 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] The present embodiment also provides a shield segment reinforcement cage welding device, including a driving device 100, a fixed track 200, a single-piece mesh mold positioning device 300 and the above-mentioned power supply device, wherein the driving device 100 is used to drive the single-piece mesh mold positioning device 300 to switch positions on the fixed track 200, and the power supply device is used to supply power to the single-piece mesh mold positioning device 300. The electrical connection between the first cable 13 and the second cable 26 is achieved by the docking of the second conductive column 25 and the first conductive column 12, thereby meeting the power demand 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 member 22 drives the insulating plate 23 to move, and the insulating plate 23 drives the second conductive column 25 to contact the first conductive column 12. The elastic member 24 is compressed and deformed, which has a pressing effect on the contact between the second conductive column 25 and the first conductive column 12, ensuring that all the second conductive columns 25 are in good contact with the first conductive column 12, which can effectively prevent the power supply connector from not being able to dock or being poorly connected, thereby improving the safety of electricity use, reducing the processing accuracy and movement accuracy requirements of the shield segment steel cage welding equipment, and ensuring the normal and stable operation of the equipment.

[0049] In order to meet the normal power supply demand 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 member 22 extends, driving the insulating plate 23 to move forward, and the second conductive column 25 contacts the first conductive column 12. The elastic member 24 is compressed and deformed, which has a pressing effect on the contact between the second conductive column 25 and the first conductive column 12, ensuring that all the second conductive columns 25 are in good contact with the first conductive column 12.

[0050] When the driving device 100 drives the single-piece mesh mold positioning device 300 to complete the position switching, the output rod of the driving member 22 retracts, and the first power supply connector 1 and the second power supply connector 2 of the power supply device are disengaged to prevent the second power supply connector 2 of the power supply device 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 to be powered.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
