[0036] A rotating lug 12 is provided on the bottom side of the right side portion 4 of the cable trough. A rotating cover 13 is connected to the rotating lug 12 . The rotating cover 13 is sleeved on the outer wall of the right supporting tube 10 .

[0037] The lock structure 6 includes a lock cylinder 14, a lock rod 15, a lock pin 16, a front lock block 17, an intermediate lock block 18, and a rear lock block 19. The lock cylinder 14 is fixed to the bottom side of the left side portion 3 of the cable trough, and the output end of the lock cylinder 14 is connected to the lock rod 15. The lock rod 15 extends along the length direction of the left support tube 9. The front lock block 17 and the rear lock block 19 are relatively symmetrically arranged at intervals on the bottom side of the left side portion 3 of the cable trough. The front lock block 17, the rear lock block 19 and the intermediate lock block 18 are respectively provided with lock holes 20 that are compatible with the lock pin 16. The intermediate lock block is arranged on the left support tube 9. The side walls of the front locking block 17 and the rear lock block 19 are respectively provided with connecting blocks 21, which are movably mounted on the lock rod 15. The lock pin 16 is arranged on the lock rod 15 through the support block 22.

[0038] An upper lifting lug 23 is provided on the left side of the cable trough top 2 , and a lower lifting lug 24 is provided on the top side of the left side portion 3 of the cable trough. The upper lifting lug 23 and the lower lifting lug 24 are connected by a rotating shaft 25 .

[0039] The front end of the cable entry mechanism 1 is hinged to the rear end of the cable trough top 2 via a rotating pin 26 .

[0040] The rear end of the cable entry mechanism 1 is open, and the bottom side of the cable entry mechanism 1 is a bottom cable opening 27, at which an opening and closing plate 28 is provided. A bottom oil cylinder 29 is provided on the side wall of the cable entry mechanism 1, and the output end of the bottom oil cylinder 29 is connected to the opening and closing plate 28.

[0041] The rear end of the cable insertion mechanism 1 and the rear end of the opening and closing plate 28 are respectively provided with cable insertion rollers 30 .

[0042] A rotating water tank 31 is provided on the top 2 of the cable trough. The bottom side of the rotating water tank 31 is connected to the right support tube 10 through a connecting tube 32. The front ends of the left support tube 9 and the right support tube 10 are respectively connected to high-pressure jet knives.

[0043] The rotating water tank 31 is a cylindrical body with open ends. The rotating water tank 31 is arranged on the top 2 of the cable trough through a base 33. Connecting ears 34 are respectively provided at both ends of the rotating water tank 31.

[0044] When in use, the rotating water tank 31 of the multifunctional cable trough is connected to the water inlet beam 35 through a rotating joint, and the water inlet beam 35 is connected to the main frame 36. High-pressure water flows into the rotating water tank 31 of the multifunctional cable trough through the water inlet beam 35. The high-pressure water enters the left support pipe 9 and the right support pipe 10 through the connecting pipe 32 at the bottom of the rotating water tank 31, and is then distributed to the high-pressure jet knife (not shown) through the left support pipe 9 and the right support pipe 10. The high-pressure jet knife provides power for breaking the ground. The rising and lowering of the multifunctional cable trough is controlled by the lowering cylinder 38. One end of the lowering cylinder 38 is connected to the main frame 36, and the other end is connected to the connecting ear 34 on the rotating water tank 31.

[0045] The cable installation of this multifunctional cable trough is divided into two forms, one is bottom cable entry and the other is side cable entry.

[0046] When the bottom cable is entered, the bottom oil cylinder 29 contracts to drive the opening and closing plate 28 to open, and the lock oil cylinder 14 contracts. The lock oil cylinder 14 drives the lock rod 15 to drive the lock pin 16 to disengage from the lock hole 20 of the rear lock block 19, the middle lock block 18, and the front lock block 17 in sequence, so that the left support tube 9 is disconnected from the left side 3 of the cable trough, and then the cable trough bottom 5 is disconnected from the left side 3 of the cable trough. At this time, the side oil cylinder 8 contracts, and the side oil cylinder 8 drives the right support tube 10 to rotate around the rotating lifting ear 12, so that the cable trough bottom 5 is turned from a horizontal state to an inclined state, so that the left support tube 9 tilts downward, thereby opening the cable trough bottom 5, and then lift the cable to the cable trough bottom 5. After the cable enters the multi-functional cable trough, the bottom oil cylinder 29 extends to drive the opening The plywood 28 is closed, and the side oil cylinder 8 is extended to drive the right supporting tube 10 to rotate around the rotating lifting ear 12, so that the bottom 5 of the cable trough is turned from an inclined state to a horizontal state. While closing the bottom 5 of the cable trough, the middle lock block 18 on the left supporting tube 9 is rotated to between the front lock block 17 and the rear lock block 19, and the lock holes 20 on the front lock block 17, the middle lock block 18 and the rear lock block 19 are located on the same straight line. Then the lock oil cylinder 14 is controlled to extend to drive the lock rod 15 to drive the lock pin 16 to insert into the lock hole 20 on the front lock block 17, the middle lock block 18 and the rear lock block 19, thereby connecting the left supporting tube 9 and the left side 3 of the cable trough, and then locking the bottom 5 of the cable trough. At this point, the cable is installed from the bottom of the multi-functional cable trough.

[0047] When the cable is inserted from the side, the top oil cylinder 7 contracts, lifts the cable insertion mechanism 1 and controls the bottom oil cylinder 29 to contract and drive the opening and closing plate 28 to open. The lock oil cylinder 14 contracts and drives the lock rod 15 to drive the lock pin 16 to disengage from the lock hole 20 of the rear lock block 19, the middle lock block 18 and the front lock block 17 in sequence, so that the left support tube 9 is disconnected from the left side 3 of the cable trough. At this time, the side oil cylinder 8 does not move, so that the bottom 5 of the cable trough remains in a horizontal state. The left side 3 of the cable trough is turned up by the hand hoist, so that the top side of the left side 3 of the cable trough rotates around the rotation axis 25. Thereby, the left side portion 3 of the cable trough is flipped up and opened, and the cable is pushed into the multifunctional cable trough from the side. Then the hand hoist is released, and the left side portion 3 of the cable trough is lowered. The lock cylinder 14 is controlled to extend to drive the lock rod 15 to drive the lock pin 16 to insert into the lock hole 20 on the front lock block 17, the middle lock block 18 and the rear lock block 19, and the bottom side of the left side portion 3 of the cable trough is locked with the left support tube 9. The top cylinder 7 extends to drive the cable entry mechanism 1 to be flat, and the bottom cylinder 29 extends to drive the opening and closing plate 28 to close. At this point, the cable is loaded from the side of the multifunctional cable trough.

[0048] When it is necessary to cast the cable, the lock cylinder 14 is controlled to retract, and the lock rod 15 is driven to drive the lock pin 16 to disengage from the lock hole 20 of the rear lock block 19, the middle lock block 18, and the front lock block 17 in sequence, disconnecting the left support tube 9 from the left side 3 of the cable trough, and the side cylinder 8 is controlled to retract. The side cylinder 8 drives the right support tube 10 to rotate around the rotating lifting ear 12, so that the bottom 5 of the cable trough is turned from a horizontal state to an inclined state, thereby opening the bottom 5 of the cable trough, and at the same time controlling the bottom cylinder 29 to drive the opening and closing plate 28 to open, so that the bottom cable opening 27 is opened, and the cable can be cast.

[0049] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not depart from the present invention should be included in the patent scope of this case.
