Description

Technical Field

[0001] The present invention relates to the field of hoisting of saddles for splayed cables, and particularly to a hoisting device and method for a large-tonnage tunnel anchor saddle for splayed cables. Background Technique

[0002] The saddle for splayed cables is a transition structure between the main cable of a suspension bridge and the anchor. Its function is to disperse and transfer the concentrated force of the main cable to the anchor, adjust the alignment of the cable strands of the main cable at the same time, disperse the cable strands of the main cable from the bundled state into single strands, evenly anchor them on the anchor, change the geometric direction of the main cable, ensure smooth transition of the force of the cable strands, and reduce local stress.

[0003] When hoisting the saddle for splayed cables in a tunnel, due to characteristics such as limited space, poor ventilation conditions, and insufficient lighting, large hoisting equipment cannot be used. Generally, multiple large-tonnage chain hoists need to be arranged on the guide rail top frame to synchronously hoist the saddle for splayed cables. After the saddle for splayed cables is moved to the designated position, one of the hoists is used to pull the suspender for stretching to adjust the angle of the saddle for splayed cables. However, in this process, only the initial angle parallel to the hoist can be adjusted for the saddle for splayed cables, and the guide rail top frame and the installation position need to be in a parallel state. If multiple saddles for splayed cables are installed, corresponding angle adjustments of the guide rail top frame are required, increasing the installation difficulty of the guide rail top frame and making it difficult to achieve multi-angle adjustment of the saddle for splayed cables.

Threaded sleeves 15 are threadedly assembled at both ends of the bidirectional screws 14. The threaded sleeves 15 are fixedly installed on the outer sides of the adjacent mounting plates 9. When the two bidirectional screws 14 rotate, the two mounting plates 9 can be driven to approach or move away from each other through the threaded sleeves 15, realizing the distance adjustment of the four winches 3, facilitating the adjustment of the position of the steel wire rope 4 according to the size of the loose cable saddle body 5.

When the first motor 16 drives the corresponding bidirectional screw 14 to rotate, the bidirectional screw 14 can drive the other bidirectional screw 14 to rotate synchronously through the synchronous belt 17, realizing the position adjustment of the mounting plate 9. A support optical axis 28 that slidably penetrates the two mounting plates 9 is fixedly installed inside the moving frame 7, improving the smoothness of the movement of the mounting plate 9.

[0024] Embodiment Three: Please refer to Figures 3 - 8, this embodiment further illustrates other embodiments. The fixed rope mechanism in the figure includes two swivel rings 18 symmetrically and rotatably installed on the outer side of the wire drum 13. Two first mounting seats 19 symmetrically distributed about the center and two second mounting seats 20 symmetrically distributed about the center are fixedly installed on the outer side of the swivel ring 18. The length of the second mounting seat 20 is greater than that of the first mounting seat 19. Wire rods 33 are fixedly installed on the outer sides of both the first mounting seat 19 and the second mounting seat 20, so that the wire rods 33 on the first mounting seat 19 and the wire rods 33 on the second mounting seat 20 are arranged in a stepped manner. One end of the wire rod 33 is rotatably installed with a swivel base 21, and the swivel base 21 is rotatably installed at the end of the wire drum 13. The steel wire rope 4 is located between the four wire rods 33. When the swivel ring 18 rotates, it can drive the wire rods 33 on the first mounting seat 19 and the second mounting seat 20 to move along the inner sides of the corresponding swivel bases 21, so that the four wire rods 33 approach the steel wire rope 4 synchronously, realizing the clamping and positioning of the steel wire rope 4, improving the stability of the steel wire rope 4 during winding and unwinding, and preventing shaking. A positioning frame 22 is fixedly installed on the outer side of the wire drum 13. A worm 23 is rotatably installed inside the positioning frame 22. A worm gear rack 24 is arranged on the outer side of the wire drum 13 and is matched with the worm 23. The worm gear rack 24 is fixedly installed on the outer side of the adjacent swivel ring 18. When the worm 23 rotates, it can drive the corresponding swivel ring 18 to rotate synchronously through the worm gear rack 24. Two struts 25 symmetrically distributed are fixedly installed between the two swivel rings 18, so that the rotating swivel ring 18 can drive the other swivel ring 18 to rotate synchronously through the two struts 25. A rotating cylinder 30 is arranged on the outer side of the wire rod 33. A plurality of positioning rings 31 symmetrically distributed about the center are fixedly installed inside the rotating cylinder 30. Annular grooves for the positioning rings 31 to be rotatably installed are formed on the outer side of the wire rod 33, so that the wire rod 33 can move downward along the outer side of the rotating cylinder 30 to provide protection for the wire rod 33 and improve the durability of the wire rod 33. And by using the friction between the steel wire rope 4 and the rotating cylinder 30, the rotating cylinder 30 drives the positioning rings 31 to rotate along the annular grooves on the wire rod 33, reducing the wear of the steel wire rope 4 on the rotating cylinder 30. A second motor 32 is fixedly installed on the outer side of the positioning frame 22. The output end of the second motor 32 is fixedly connected to one end of the worm 23, and the rotation of the worm 23 can be adjusted through the second motor 32.

[0025] Working principle: First, the staff starts the guide rail top frame 1, so that the guide rail top frame 1 drives the moving frame 7 to move directly above the main body of the saddle 5 through the moving socket 8. Then, the staff starts the first motor 16, so that the first motor 16 drives the corresponding bidirectional screw 14 to rotate. The bidirectional screw 14 drives another bidirectional screw 14 to rotate synchronously through the synchronous belt 17. The two bidirectional screws 14 drive the two mounting plates 9 to approach each other along the inner side of the moving frame 7 through the moving sleeves 15, so that the winches 3 on the mounting plates 9 move synchronously. The steel wire ropes 4 on the winches 3 approach the docking points of the main body of the saddle 5. At this time, the staff installs the lifting tool 6 on the steel wire rope 4 at the connection point of the main body of the saddle 5 to achieve the four-corner positioning of the main body of the saddle 5. Subsequently, the staff starts the second motor 32, so that the second motor 32 drives the worm 23 to rotate. The worm 23 drives the corresponding rotating ring 18 to rotate synchronously through the worm gear rack 24. The rotating ring 18 drives another rotating ring 18 to rotate synchronously through the two support rods 25, so that the rotating ring 18 drives the wire rods 33 on the first mounting seat 19 and the second mounting seat 20 to move along the inner side of the corresponding rotating seat 21. The four wire rods 33 approach the steel wire rope 4 synchronously. The rotating drums 30 on the outer sides of the wire rods 33 can be in contact with the outer side of the steel wire rope 4 to achieve the clamping and positioning of the steel wire rope 4. Then, the staff starts the four winches 3, so that the winches 3 take in the steel wire ropes 4. The steel wire ropes 4 can be vertically taken in upward along the outer sides of the rotating drums 30, and then the main body of the saddle 5 can be stably lifted. Then, through the guide rail top frame 1, the moving frame 7 is moved directly above the installation position of the main body of the saddle 5, so that the main body of the saddle 5 is close to the installation position. Finally, the staff starts the winch 3 corresponding to the inclined position of the installation position, so that the winch 3 pulls up a corner of the main body of the saddle 5 through the steel wire rope 4 and the lifting tool 6, so that the main body of the saddle 5 is in an inclined state, and the staff can install the main body of the saddle 5, thus achieving the effect of multi-angle installation, improving the stability and convenience of the hoisting of the main body of the saddle 5, and further improving the installation efficiency of the main body of the saddle 5.
