[0002] The lateral installation position of each arch rib of the inward-inclined basket arch bridge changes segment by segment. For arch ribs in different lateral positions, the relative lateral spacing between the upstream and downstream main cables and the middle main cable needs to be adjusted accordingly to change the position of the suspension point.

[0003] Currently, the construction method of increasing the number of main cables and working cables is usually adopted to meet the requirements of lateral adjustment of the on-site lifting point position. This construction method has problems such as slow construction speed, low construction efficiency, high cost, and large mutual interference between cables. Utility Model Content

[0004] This utility model provides a lateral movement mechanism for the main cable and working cable of a cable crane and a cable tower, which solves the problem of low construction efficiency in the lateral adjustment of the lifting point position in the prior art.

[0006] A cable saddle pad beam is detachably connected to the top of the cable tower, and the cable saddle pad beam is equipped with the main cable and the working cable;

[0007] A driving device is disposed at the top of the cable tower. The driving device acts on the cable saddle pad beam and is used to drive the cable saddle pad beam to move in a first direction when the cable saddle pad beam is disconnected from the cable tower.

[0008] According to the cable crane main cable and working cable transverse movement mechanism provided by this utility model, the cable saddle pad beam is provided with a main cable saddle and a working cable saddle, the main cable is provided on the main cable saddle, and the working cable is provided on the working cable saddle.

[0009] According to the cable crane main cable and working cable transverse movement mechanism provided by this utility model, a steel box distribution beam is provided on the top of the cable tower, and the cable saddle pad beam is detachably connected to the steel box distribution beam.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1-2 This invention describes a cable crane main cable and working cable traversing mechanism and cable tower.

[0025] This utility model provides a lateral movement mechanism for the main cable and working cable of a cable crane, including: a cable saddle pad beam and a drive device 2.

[0026] The cable saddle pad beam is detachably connected to the top of the cable tower, and the cable saddle pad beam is equipped with the main cable 1 and the working cable; the drive device 2 is located at the top of the cable tower and acts on the cable saddle pad beam to drive the cable saddle pad beam to move along the first direction at the top of the cable tower when the cable saddle pad beam is disconnected from the cable tower. The first direction is the length direction of the top of the cable tower and is perpendicular to the main cable 1.

[0027] With this configuration, when the cable position needs to be adjusted, this invention uses the drive device 2 to drive the saddle pad beam to move laterally along the first direction at the top of the tower in an unloaded state while disconnecting it from the cable tower. This causes the main cable 1 and the working cable to slide together to the required position. Then, the saddle pad beam is re-fixed to the top of the cable tower. This avoids increasing the number of main cables and working cables along the length direction at the top of the tower, reduces the amount of cable material used, and also reduces the labor, time, and cost required for installing and maintaining additional cables. The device has a simple structure, is easy to manufacture, has low processing cost, is convenient to install and dismantle, and is safe to operate, making it suitable for widespread application.

[0028] In some embodiments, a main cable saddle 4 and a working cable saddle 5 are provided on the cable saddle pad beam, with the main cable 1 disposed on the main cable saddle 4 and the working cable disposed on the working cable saddle 5; such as Figure 2 As shown, the main cable 1 is supported in the mounting groove of the main cable saddle 4 by pulleys, and the working cable is supported in the mounting groove of the working cable saddle 5 by pulleys. The main cable saddle 4 is used to support and transmit the huge tension of the main cable to the cable tower, ensuring that the main cable changes direction smoothly at the top of the tower and evenly transmits the tension of the main cable 1 to the support at the top of the tower or the anchorage. The working cable saddle 5 is used to support and guide the working cables such as lifting cables and traction cables, and realizes the lifting and traction functions of the working cables through the pulley system.

[0029] In some embodiments, a steel box distribution beam 6 is provided on the top of the cable tower, and the cable saddle pad beam is detachably connected to the steel box distribution beam 6. For example, the cable saddle pad beam is connected to the top of the steel box distribution beam 6 by bolts. When it is necessary to move the working cable and the main cable 1 laterally, the connection between the cable saddle pad beam and the steel box distribution beam 6 is released by removing the bolts. After the movement is completed, the cable saddle pad beam and the steel box distribution beam 6 are fixedly connected by tightening the bolts.

[0030] In this embodiment, the steel box distribution beams 6 on both sides of the cable saddle pad beam are respectively provided with positioning seats 7. The driving device 2 is connected to the positioning seats 7, so that the driving device 2 can be selectively connected to the positioning seats 7 on both sides respectively, so as to realize bidirectional lateral movement of the working cable and the main cable 1.

[0031] This configuration is used to fix the position of the drive device 2 by the positioning seat 7 when the working cable and the main cable 1 need to be moved laterally, so as to prevent the reverse force generated when the drive device 2 is applied from causing the position of the drive device 2 to shift or move, thus affecting the working effect.

[0032] Optionally, the drive device 2 includes a hydraulic jack and a connecting shaft 8. The hydraulic jack is mounted on the positioning seat 7, and the connecting shaft 8 passes axially through the cable saddle pad beam and is connected to the cable saddle pad beam. The drive rod of the hydraulic jack is connected to the end of the connecting shaft 8. That is, both the drive rod and the connecting shaft 8 are arranged along the first direction and are axially connected. For example, the cable saddle pad beam has a through hole along the first direction, and part of the shaft of the connecting shaft 8 is threaded. The connecting shaft 8 passes through the through hole, and nuts are used to thread the connecting shaft 8 at both ends of the through hole to achieve a fixed connection between the connecting shaft 8 and the cable saddle pad beam.

[0033] Furthermore, a limiting block 9 is provided at the end of the cable saddle pad beam. The limiting block 9 is connected to the outer side of the steel box distribution beam 6. For example, the limiting block 9 is welded to both ends of the cable saddle pad beam and fixedly connected to the steel box distribution beam 6 by bolts, forming a clamping effect on the steel box distribution beam 6 to ensure that the cable saddle pad beam always moves in a straight line without deviating.

[0034] In this embodiment, the cable saddle support beam includes a main cable support beam 10 and a working cable support beam 11. The main cable saddle 4 is disposed on the main cable support beam 10, and the working cable saddle 5 is disposed on the working cable support beam 11. Figure 1 As shown, the main cable pad beam 10 and the working cable pad beam 11 are spaced apart. Both the main cable pad beam 10 and the working cable pad beam 11 have through holes along the first direction. The connecting shaft 8 passes through both through holes at the same time. Nuts are provided at both ends of the through holes. The nuts are used to fix the main cable pad beam 10 to the connecting shaft 8 and the working cable pad beam 11 to the connecting shaft 8, respectively. This also ensures that the distance between the working cable and the main cable 1 does not change when they move.

[0035] In this embodiment, the distance between the main cable saddle 4 and the working cable saddle 5 is 2m.

[0036] This utility model also provides a cable tower, including a tower 3, with at least two sets of the above-mentioned cable crane main cable and working cable traversing mechanisms arranged on the top of the tower 3 along a first direction.

[0037] In some embodiments, a fixed saddle pad beam 13 is also provided between the main cable saddles of the two sets of cable crane main cables and the working cable traverse mechanism, and a fixed main cable saddle 12 is provided on the fixed saddle pad beam 13; that is, in this embodiment, the cable crane is designed with a total of 3 sets of main cables upstream, middle and downstream, and 2 sets of working cables.

[0038] According to construction needs, such as Figure 1 As shown, when the main cable 1 and the working cable need to move laterally to the left under no-load conditions, a hydraulic jack is connected to the left end of the connecting shaft 8. The connecting bolts between the steel box distribution beam 6 and the two pad beams are released, and the hydraulic jack is used to pull the two pad beams to move laterally to the left in sync. This causes the cable and the saddle to slide laterally to the left to the required position. Then, the steel box distribution beam 6 and the two pad beams are fixedly connected by bolts. When the main cable 1 and the working cable need to move laterally to the right under no-load conditions, a hydraulic jack is connected to the left end of the connecting shaft 8. The remaining steps are the same as described above and will not be repeated.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
