Description

Technical Field

[0001] The present invention relates to the field of loose cable saddle hoisting, and in particular to a large-tonnage tunnel anchor loose cable saddle hoisting device and method. Background Art

[0002] The loose cable saddle is a transition structure between the main cable and the anchor of a suspension bridge. Its function is to disperse the concentrated force of the main cable to the anchor, while adjusting the direction of the main cable strands, dispersing the main cable strands from a bundled state into single strands, and evenly anchoring them on the anchor, thus changing the geometric direction of the main cable, ensuring a smooth transition of the force on the cable strands, and reducing local stress.

[0003] When lifting the loose cable saddle in the tunnel, due to the limited space, poor ventilation conditions, insufficient lighting and other characteristics, large-scale lifting equipment cannot be used. Generally, multiple large-tonnage chain pulleys need to be arranged on the guide rail top frame to lift the loose cable saddle synchronously. After the loose cable saddle is moved to the specified position, one of the pulleys pulls the lifting rod to stretch it to adjust the angle of the loose cable saddle. However, in this process, only the initial angle of the loose cable saddle and the pulley relative to each other can be adjusted. The guide rail top frame needs to be parallel to the installation position. If multiple loose cable saddles are installed, the guide rail top frame needs to be adjusted to the corresponding angle, which increases the difficulty of installing the guide rail top frame and makes it difficult to achieve multi-angle adjustment of the loose cable saddle.

[0038] 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 to the top of the cable saddle body 5 through the moving sleeve 8, and then the staff starts the first motor 16, so that the first motor 16 drives the corresponding bidirectional screw 14 to rotate, and the bidirectional screw 14 drives the other bidirectional screw 14 to rotate synchronously through the synchronous belt 17, and 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 sleeve 15, so that the winch 3 on the mounting plate 9 moves synchronously, and the wire rope 4 on the winch 3 is close to the docking point of the cable saddle body 5. At this time, the staff installs the sling 6 on the wire rope 4 at the connection of the cable saddle body 5 to achieve the four corner positioning of the cable saddle body 5, and then the staff starts the second motor 32, so that the second motor 32 drives the worm 23 to rotate, and the worm 23 drives the corresponding swivel 18 to rotate synchronously through the worm gear rack 24, and the swivel 18 drives another swivel 18 to rotate synchronously through the two support rods 25, so that the swivel 18 drives the first mounting seat 19 and the conductor rod 33 on the second mounting seat 20 move along the inner side of the corresponding rotating seat 21, and the four conductor rods 33 are synchronously close to the wire rope 4. The rotating drum 30 outside the conductor rod 33 can contact the outer side of the wire rope 4 to achieve the clamping and positioning of the wire rope 4. Then, the staff starts the four winches 3 to make the winches 3 take up the wire rope 4. The wire rope 4 can be stored upward in a vertical state along the outer side of the rotating drum 30, and the saddle body 5 can be lifted steadily. Then, the movable frame 1 is moved to the upper frame 1 through the guide rail. The frame 7 is moved to the top of the installation position of the loose cable saddle body 5, so that the loose cable saddle body 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 one corner of the loose cable saddle body 5 through the wire rope 4 and the sling 6, so that the loose cable saddle body 5 is in an inclined state. The staff can then install the loose cable saddle body 5, thereby achieving the effect of multi-angle installation, improving the stability and convenience of the lifting of the loose cable saddle body 5, and thus improving the installation efficiency of the loose cable saddle body 5.
