[0025] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein may be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0027] The following combination Figures 1-6 The specific implementation mode of the present invention is described. A chute line power supply system suitable for bridge engineering includes multiple chute lines and multiple power supply devices. Any chute line includes a conductor 11 and a sheath 12 wrapped around the outside of the conductor 11. Any two connected chute lines form a joint area at the position close to each other. The conductor 11 at the joint area is exposed outside the sheath 12, and the power supply device is installed at the joint area. In the beam yard required for the construction of the bridge project, a longitudinal power supply main cable needs to be buried. The gantry crane busbar is parallel to the main cable. By adding a power supply device at the joint of the two chute lines and connecting the power to the secondary distribution box, the purpose of power supply for the beam yard production is achieved. Compared with the traditional power supply method, the laying of the longitudinal main cable in the beam yard is saved, and the power connection is more convenient.

[0028] The power-taking device includes an insulating cover 16, a power-taking groove 25 installed on the conductor 11 and located in the insulating cover 16, a plurality of control bolts 35 installed on the power-taking groove 25, a wire 13 connected to the power-taking groove 25, and a clamp 15 for controlling the position of the wire 13; the working environment of the beam yard is harsh, and watering is required when the beams and slabs are maintained. Therefore, the cables in the beam yard have very high requirements for waterproof performance, especially at the joint position of the busbar. In order to avoid the added power-taking device affecting the original waterproof effect, the joint area and the section of the wire 13 that is not covered with insulation are fully covered.

[0029] The clamping ring 15 is rotatably arranged between two fixing rings 18, and the two fixing rings 18 are respectively connected to the insulating cover 16. A wire hole 19 is provided on the side of the clamping ring 15, and the wire 13 passes through the wire hole 19 and is connected to the control bolt 35. The busbar is straight, and there are no obstacles in the straight path where it is located and within a certain range on both sides. Electrical equipment or secondary distribution boxes are also set on both sides of the busbar. The position and posture of the wire 13 are restricted by the clamping ring 15, which facilitates the management of the wire harness. The posture of the wire 13 is reasonably planned according to the position of the electrical equipment or the secondary distribution box, reducing the entanglement of the wire 13 in the joint area, ensuring that the posture of the wire 13 in the joint area always remains unchanged and is in a natural state without external force. The joint of the wire 13 will not loosen easily, avoiding the occurrence of faults such as poor contact.

[0030] Advantageously, two insulating covers 16 are provided, symmetrically connected by bolts. The insulating covers 16 include a top shell, a bottom shell 24, and a connecting plate 27 for connecting the top shell and the bottom shell 24. The bottom shell 24 is used to enclose the busbar and has the same function as a conventional insulating protective shell for the busbar joint area. The top shell is used to enclose the power supply slot 25 and the conductor 13, ensuring that the joint area is effectively protected.

[0031] Advantageously, the top shell includes multiple mounting portions 21 and connecting portions 26 arranged in a staggered, stepped pattern. A connecting hole 17 is provided on one side of the connecting portion 26, and the fastening bolt engages with the connecting hole 17. The ends of the connecting plate 27 are respectively fixedly connected to the middle connecting portion 26 and the bottom shell 24. The staggered, stepped pattern of mounting portions 21 and connecting portions 26 ensures a good connection between the two insulating covers 16 while creating space within the mounting portion 21 for accommodating the control bolt 35 and the wire 13.

[0032] Advantageously, there is a gap between the top shell and the bottom shell 24, and the retaining ring 15 is located in the gap between the top shell and the bottom shell 24. After the two insulating covers 16 are spliced ​​together, an installation space is formed in the installation portion 21. A closing disk 14 is detachably installed on one side of the installation space, and a connecting buckle 22 is fixed to the end of the closing disk 14 away from the bottom shell 24, and both ends of the connecting buckle 22 are snapped into the inner wall of the installation space.

[0033] Advantageously, a limit plate 20 is fixedly mounted on one end of the bottom shell 24 near the top shell, and the snap ring 15 is positioned between the closing disk 14 and the limit plate 20. The closing disk 14 and the limit plate 20 are respectively engaged with the two fixing rings 18. The insulating cover 16 is entirely made of plastic, and the gap between the top shell and the bottom shell 24 allows for minimal deformation.

[0034] Advantageously, there are two clamping rings 15, at least one of which is removably mounted with a sealing plug 23. The sealing plug 23 engages with the wire hole 19. The clamping ring 15 without the sealing plug 23 is connected to the wire 13. A contact pad 29 is fixed to one end of the wire 13 located within the insulating cover 16, forming a transition portion 28 between the contact pad 29 and the wire 13. The two clamping rings 15 are located at either end of the connector area. When power is temporarily not needed at this power supply device, the two bottom shells 24 and the closing disk 14 can be directly installed and secured with fastening bolts. The sealing plug 23 isolates the space inside the insulating cover 16 from the outside world. When power is needed at this power supply device, an appropriate control bolt 35 is selected based on the orientation of the power-consuming device relative to the power supply device. The contact pad 29 of the wire 13 is inserted into the screw of the desired control bolt 35. The insulation on the surface of the wire 13 seals the wire hole 19, similarly isolating the space inside the insulating cover 16 from the outside world.

[0035] Advantageously, a slot 38 is formed at one end of the conductor 11 near the top shell, and a connecting piece 33 is detachably installed in the slot 38. A plurality of through holes 31 are provided on the power extraction slot 25, and a plurality of alignment holes 32 are provided on the connecting piece 33. The through holes 31 correspond to the alignment holes 32. The wire 13 and the conductor 11 are connected through the control bolt 35, the gasket 34, the connecting piece 33, the slot 38, the power extraction slot 25, the contact pad 29 and the nut 30 installed in sequence, so that the wire 13 can be electrically connected to the conductor 11, thereby achieving the purpose of power extraction.

[0036] Advantageously, the control bolts 35 are divided into two groups, one at each end of the connector area. The two control bolts 35 furthest from each other are used for power extraction, while the remaining control bolts 35 are used for tightening. The control bolts 35 can be designed with different lengths depending on the intended use. The control bolts 35 on both sides connect to the conductors 13, allowing them to have more space for adjustment. The conductors 13 can be arranged not only along the length of the conductor 11 but also perpendicular to its length.

[0037] Advantageously, each closing disk 14 corresponds to two limiting disks 20. After the two insulating covers 16 are joined, an annular notch 36 and a fan-shaped notch 37 are formed between the two limiting disks 20. In each set of control bolts 35, one control bolt 35 used for power extraction is located within the annular notch 36, while the remaining control bolts 35 are located within the fan-shaped notches 37. The annular notch 36 provides space for rotational adjustment of the contact pad 29, while the fan-shaped notch 37 provides space for installing other control bolts 30 not used for power extraction.

[0038] Advantageously, after the two insulating covers 16 are joined and secured with the fastening bolts, their interior spaces are isolated from the outside world. After the nut 30 compresses the contact pad 29, the position of the wire 13 is fixed, and the clamping ring 15 and the two fixing rings 18 do not rotate. The contact pads 29 completely restrain the wire 13, preventing it from easily rotating. This allows the clamping ring 15 and fixing ring 18 to maintain a non-rotating relative position for an extended period of time.

[0039] Working principle of the present invention:

[0040] In the initial state, the chute line of this application is installed and the power supply device is in a disassembled state.

[0041] The cost of electricity can be reduced by installing a power take-off device. The installation process of the power take-off device is as follows:

[0042] First, find the joint area of ​​the chute line, remove the protective device at the original joint position, and separate the conductors 11 in the joint area; connect two control bolts 35, two gaskets 34 and a connecting piece 33 in sequence into a group, prepare two groups, and install them in the slots 38 of the two conductors 11 respectively. After re-docking the two conductors 11, install the power extraction slot 25 on top of them, so that the through hole 31 and the alignment hole 32 correspond one to one, and make the screw of the control bolt 35 pass through the through hole 31. Use a wrench to insert into the conductor 11 to limit the rotation of the nut of the control bolt 35, and then screw the nut 30 on it.

[0043] When it is temporarily not necessary to draw power from this power-drawing device, the two bottom shells 24 and the closing disk 14 can be directly installed and fixed with fastening bolts. When it is necessary to draw power from this power-drawing device, according to the orientation of the power-consuming device relative to the power-drawing device, a suitable control bolt 35 is selected, and the contact pad 29 of the wire 13 is passed through the screw of the target control bolt 35. The nut 30 is used to restrict it between the power-drawing slot 25 and the nut 30, so that the contact pad 29 rotates around the target control bolt 35, and the posture of the wire 13 is adjusted so that it faces the side where the power-consuming device is located, making the cables easier to organize.

[0044] During the installation process of the above-mentioned wire 13, the clamping ring 15 and the two fixing rings 18 are already in a connected state. The clamping groove and flange at the end prevent the three from separating and can rotate relative to each other. The clamping ring 15 is made of rubber and has a certain toughness. Take out the sealing plug 23 and save it. Pass the wire 13 through the clamping ring 15, so that the contact pad 29 passes through the wire hole 19, and let the contact pad 29 be located in the center of the wire hole 19, and then put it on the target control bolt 35.

[0045] Then, the two closing disks 14 are respectively installed on the upper sides of the two clamping rings 15, so that the closing disk 14 and the upper fixing ring 18 are matched and clamped. Next, the two insulating covers 16 are installed in sequence. First, one of the insulating covers 16 is installed so that the bottom shell 24 wraps the conductor 11, and the two ends of the bottom shell 24 are respectively in contact with the sheath 12 on both sides, so that the limiting disk 20 is matched and clamped with the lower fixing ring 18, and the two ends of one side of the connecting buckle 22 are in contact with the inner wall of the installation space; when installing the second insulating cover 16, the insulating cover 16 is inserted by opening the gap between the top shell and the bottom shell 24, so that the limiting disk 20 of the second insulating cover 16 is matched and clamped with the lower fixing ring 18, so that the two ends of the other side of the connecting buckle 22 are in contact with the inner wall of the installation space of the second insulating cover 16.

[0046] After the two insulating covers 16 are installed, the connecting holes 17 correspond to each other one by one, and the two insulating covers 16 are completely fixed by tightening the bolts. The space inside the two insulating covers 16 is completely isolated from the outside space, so that the control bolts 35 used for power supply and the joints of the wires 13 have a good working environment and will not be affected by the harsh environment of the beam yard.
