Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and more specifically to a cable support for long-span cable hoisting. Background Technology

[0002] When transporting and installing bridge structural components, the supportless cable crane system is often used. The basic components of the cable crane are the load-bearing cable (main cable), cable trolley (moving trolley), lifting rope, traction rope, backing cable, crane tower and anchoring system.

[0003] When the cable span is large, in order to solve the problem of insufficient counterweight at the lifting point and reduce the traction force of the front traction cable, and to ensure effective protection of the lifting rope and traction rope from damage by components and welding, and to prevent accidents such as various wire ropes twisting together in the air, the cable crane should be equipped with a cable support for the lifting rope and traction rope in addition to the basic components.

[0004] Cable supports are typically installed at regular intervals, and adjacent cable supports are connected by steel wire ropes, as are the cable supports and the antenna trolley, and the cable supports and the tower top slewing pulley. This type of cable support moves with the antenna trolley, hence it is called a passive cable support (or traditional cable support). In a traditional cable support, when the lifting point moves to the left of the cable span, the cable supports on the left move closer together, and the connecting steel wire ropes sag, while the connecting steel wire ropes between the cable supports on the right are tightened. Conversely, when the lifting point moves to the right of the cable span, the cable supports on the right move closer together, and the connecting steel wire ropes sag, while the connecting steel wire ropes on the left are straightened. After repeated cycles, the sagning connecting steel wire ropes will twist and eventually break, causing the cable support to fail. Meanwhile, during use, due to wind forces, changes in the lifting points and weight, and variations in the position of the lifting points, situations may occur where the supporting cable and the main cable cross and become entangled, or the supporting cable and the main cable leave the relevant pulleys and rub against the supporting cable wall plate, directly affecting the safety of the cable system. On the other hand, the spacing between supporting cables is often small (generally around 20m), requiring a large number of supporting cables, which is uneconomical.

[0005] Therefore, how to provide a cable support that is both economical and ensures the safety of long-span cable systems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a cable support for long-span cable hoisting, aiming to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A cable support for long-span cable hoisting includes a wall panel and rolling elements;

[0009] The wall panel is provided in two pieces and arranged symmetrically at intervals, and the two wall panels are fastened together by connectors;

[0010] The rolling element includes a main cable support wheel, a traction cable support wheel, and a lifting guide wheel; the main cable support wheel is rotatably connected to the upper end of the two wall panels to carry the main cable, the traction cable support wheel is rotatably connected to the middle of the two wall panels to carry the traction cable, and the lifting guide wheel is rotatably connected to the lower end of the two wall panels to carry the lifting cable.

[0011] The beneficial effect of this utility model is that the main cable support wheel, traction cable support wheel and lifting cable guide wheel are respectively set on the main cable, traction cable and lifting cable, which effectively constrains the main cable, traction cable and lifting cable. Therefore, the distance between the cable supports can be increased by reducing the number of cable supports, thus reducing the construction cost.

[0012] Preferably, the main cable support wheel, the traction cable support wheel, and the lifting cable guide wheel each include two axles. Both axles are rotatably connected between opposite side panels of the two wall panels and are arranged vertically. Multiple spaced semi-circular grooves are formed on the circumference of each axle. These semi-circular grooves interlock to form a circular cavity for the main cable, traction cable, or lifting cable to pass through. The rolling element is rotatably connected between the two wall panels via the axles, and a shuttle space is formed between the two axles through the two semi-circular grooves, allowing the rolling element to slide along the main cable, traction cable, and lifting cable.

[0013] Preferably, the assembly also includes bearings and a steel shaft; the axle is continuous at both ends; there are two bearings, each embedded at one end of the axle; the steel shaft is located within the axle cavity, and its outer end is embedded in the inner ring of the bearing; both ends of the steel shaft are respectively bolted to two wall plates. The steel shaft serves as the support shaft for the axle, and the axle can rotate relative to the steel shaft through the bearings.

[0014] Preferably, the connector is a connecting plate, with its two ends welded to the top sidewalls of the two opposing wall panels. The connecting plate, in conjunction with the steel shaft, ensures the stability of the two wall panels' fastening.

[0015] Preferably, the connecting plate includes a long connecting plate and a short connecting plate; the end of the long connecting plate is fixed to the top sidewall of the wall panel; the panel of the short connecting plate abuts against the panel of the end of the long connecting plate, and one end of the short connecting plate is welded to the panel of the wall panel. The connecting end plate can reinforce the end of the long connecting plate, ensuring that the cable support has sufficient rigidity and will not crack during the sliding process.

[0016] Preferably, the connecting short plate and the connecting long plate are locked together by bolts, ensuring an effective connection between them.

[0017] Preferably, the connector further includes sleeve bolts; corresponding bolt holes are formed in the middle of the two wall panels, and the two ends of the sleeve bolts pass through the two bolt holes respectively and are fastened to the wall panels with nuts. The sleeve bolts further improve the reliability of the connection between the two wall panels.

[0018] Preferably, there are multiple cable supports arranged side-by-side along the main cable. The upper panels of the wall plates on each cable support have perforations through which steel wire ropes pass to connect the multiple cable supports in series. Under the active traction force of the steel wire ropes, the sag of the steel wire ropes in the multiple cable supports is less than that in existing cable supports. This ensures that the main cable, traction cable, and lifting cable do not sag at the axle, and that they operate in an orderly manner between the axle. During operation, there will be no entanglement of the main cable, traction cable, or lifting cable, nor friction between the main cable and the traction cable / lifting cable on the wall plate, which would affect the safety of the hoisting system. This ensures the effectiveness of the cable supports and thus guarantees the safety of the large-span cable system.

[0019] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a cable support device for long-span cable hoisting. The main cable support wheel, traction cable support wheel and lifting guide wheel are respectively set on the main cable, traction cable and lifting cable, which effectively constrains the main cable, traction cable and lifting cable. Therefore, the distance between the cable supports can be increased by reducing the number of cable supports, thereby reducing the construction cost.

[0020] Under the active traction force of the wire rope, the sag of the wire rope in multiple cable supports is smaller than that in existing cable supports. This ensures that the main cable, traction cable, and lifting cable do not sag at the wheel axle, and that they operate in an orderly manner between the wheel axle. During operation, there will be no entanglement of the main cable, traction cable, and lifting cable, or friction between the main cable and the traction cable / lifting cable against the wall panel, which would affect the safety of the hoisting system. This ensures the effectiveness of the cable supports and thus guarantees the safety of the long-span cable system. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See appendix Figures 1-4 This utility model discloses a cable support for long-span cable hoisting, including a wall plate 1 and a rolling element 3;

[0030] The wall panel 1 consists of two pieces arranged symmetrically at intervals, and the two wall panels 1 are fastened together by connectors;

[0031] The rolling element 3 includes a main cable support wheel 31, a traction cable support wheel 32, and a lifting guide wheel 33; the main cable support wheel 31 is rotatably connected to the upper end of the two wall panels 1 to pass through the main cable 4, the traction cable support wheel 32 is rotatably connected to the middle of the two wall panels 1 to pass through the traction cable 5, and the lifting guide wheel 33 is rotatably connected to the lower end of the two wall panels 1 to pass through the lifting cable 6.

[0032] In this embodiment, the main cable support wheel 31, the traction cable support wheel 32, and the lifting cable guide wheel 33 each include two axles 34. The two axles 34 are rotatably connected between the two opposite side panels of the two wall panels 1 and are arranged vertically. The circumferential surfaces of the two axles 34 are provided with a plurality of semi-circular grooves 35 arranged at intervals. The semi-circular grooves 35 on the two axles 34 interlock to form a circular cavity for passing through the main cable 4, the traction cable 5, or the lifting cable 6.

[0033] In this embodiment, there are multiple cable supports, which are arranged in parallel along the main cable 4. The upper panel of the wall plate 1 on the multiple cable supports has a through hole 11, and the wire rope passes through the through hole 11 to connect the multiple cable supports in series.

[0034] like Figure 2 and 3 As shown, two wheel axles are arranged vertically opposite each other, and two semi-circular grooves on their outer walls form a circular cable-passing cavity for threading the main cable, traction cable, and lifting cable. The rotation of the wheel axles allows the cable support to slide along the main cable, traction cable, and lifting cable. The main cable, traction cable, and lifting cable are effectively constrained by the three sets of wheel axles, thus increasing the spacing between the cable supports by reducing the number of cable supports and reducing construction costs.

[0035] Meanwhile, under the active traction force of the wire rope, the sag of the wire rope of multiple cable bearings is smaller than that of existing cable bearings. This ensures that the main cable, traction cable, and lifting cable do not sag at the wheel axle, and that the main cable, traction cable, and lifting cable run orderly between the wheel axle. During operation, there will be no entanglement of the main cable, traction cable, and lifting cable, or friction between the main cable and the traction cable / lifting cable on the wall panel, which would affect the safety of the hoisting system. This ensures the effectiveness of the cable bearing and thus guarantees the safety of the long-span cable system.

[0036] To further optimize the above technical solution, the distance between two adjacent cable carriers shall not be less than 30m, and the distance between the cable carrier adjacent to the sports car shall be 1m and connected to the sports car by steel profile.

[0037] To further optimize the above technical solution, the wheel axle is made by turning nylon rods, which can ensure the effectiveness of the cable bearing sliding along the cable; the steel axle is made by turning 45# round steel with a diameter of 40mm; and the wire rope is a non-twisted steel wire rope with a diameter of 13mm.

[0038] In other specific embodiments, to ensure the axle is fixed between the two wall panels and to ensure that the axle can rotate relative to the wall panels, a bearing 36 and a steel shaft 37 are also included; the axle 34 is through at both ends; there are two bearings 36, which are respectively embedded at both ends of the axle 34; the steel shaft 37 is located in the inner cavity of the axle 34 and its outer end is embedded in the inner ring of the bearing 36; the two ends of the steel shaft 37 are respectively bolted to the two wall panels 1.

[0039] In this embodiment, the connector is a connecting plate 2, with both ends of the connecting plate 2 welded to the top sidewalls of the two opposing panels of the two wall panels 1. The two wall panels are connected by fixing the connecting plate to the upper end of the wall panels, without affecting the installation of the rolling element.

[0040] To further optimize the above technical solution and improve the rigidity of the connecting plate to the wall panel, the connecting plate 2 includes a connecting long plate 21 and a connecting short plate 22; the end of the connecting long plate 21 is fixed to the top side wall of the wall panel 1; the panel of the connecting short plate 22 abuts against the panel at the end of the connecting long plate 21, and one end of the connecting short plate 22 is welded to the panel of the wall panel 1. The connecting short plate 22 and the connecting long plate 21 are locked together by bolts.

[0041] In some other specific embodiments, in order to further improve the firmness of the connection between the two wall panels, the connector also includes a sleeve bolt 7; the two wall panels 1 have corresponding bolt holes in the middle, and the two ends of the sleeve bolt 7 pass through the two bolt holes respectively and are fastened to the wall panels 1 by nuts.

[0042] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
