Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction and relates to a combined large-tonnage cable crane anchor seat for bridge construction using a cable crane. Background Art

[0002] The cable hoist structure involves a variety of cables, such as the main cable load-bearing cable, traction cable, lifting cable, cable tower pressure cable, etc. The two ends of each cable are anchored on the anchors on both sides. The anchors have anchor seats corresponding to each cable anchor. Multiple anchor seats are arranged in a row on the anchors, and the cables are connected to the guide wheels on the anchor seats. Usually, there are anchor cable through holes at both ends of each anchor seat, and the anchor cables and anchor seats are anchored by anchor cables embedded in the rock formation. In order to ensure the anchoring force of the anchor cable, the rear end of the anchor cable is usually embedded in the rock formation to a depth of tens of meters, and the construction cost is relatively high. However, due to the different force requirements of different types of cables, for cables with lower load-bearing requirements, their anchor seats are anchored by anchor cables, and the anchoring force will have a large redundancy, which increases the construction cost. For the main load-bearing cables with the highest load-bearing requirements, sometimes the anchor cable anchoring force is insufficient due to the low hardness of the rock formation, which poses certain safety hazards. Summary of the invention

[0003] The utility model aims to solve the above problems and provide a combined large-tonnage cable suspension cable anchor seat, which reduces the installation and construction cost of the anchor seat and ensures the anchoring force between the anchor seat and the anchor.

[0004] The technical solution of the utility model is as follows:

[0005] A combined large-tonnage cable suspension anchor seat comprises an anchor beam, an anchor cable through hole is vertically arranged at both ends of the anchor beam, and an ear plate is welded on both sides of the anchor beam. It is characterized in that: the length of the welding part between the ear plate and the anchor beam is equal to the length of the anchor beam, an anchor block is welded at both ends of the outer side of each ear plate, and an anchor rod through hole is vertically arranged on each anchor block; a pin shaft through hole is arranged between the parts of the two ear plates higher than the anchor beam, and a pin rod insertion hole that penetrates the anchor beam is arranged in the middle of the welding part between the two ear plates and the anchor beam.

[0006] The utility model is provided with anchor rod through holes and anchor cable through holes on the anchor seat, which can provide different anchoring methods according to different load-bearing requirements, which is beneficial to reducing construction costs. At the same time, a pin rod through hole is added on each anchor seat, which is convenient for connecting a row of anchor seats into one body through the pin rod, and each anchor seat is stressed together, avoiding the safety hazard caused by insufficient anchoring force of a single anchor seat, and meeting the load-bearing requirements of the load-bearing cable of a fully loaded large-tonnage cable crane. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a structural schematic diagram of the utility model;

[0008] Figure 2 This is a vertical view of a usage mode of the utility model;

[0009] Figure 3 It is a plan view of a usage mode of the utility model. DETAILED DESCRIPTION

[0010] like Figure 1 As shown, the utility model comprises an anchor beam 1, an anchor cable through hole 2 is vertically arranged at both ends of the anchor beam, an ear plate 3 is welded on both sides of the anchor beam, the length of the welding part between the ear plate and the anchor beam is equal to the length of the anchor beam, an anchor block 4 is welded at both ends of the outer side of each ear plate 3, and an anchor rod through hole 5 is vertically arranged on each anchor block; a pin shaft through hole 6 is arranged between the parts where the two ear plates are higher than the anchor beam, and a pin rod insertion hole 7 that penetrates the anchor beam is arranged in the middle of the welding part between the two ear plates and the anchor beam.

[0011] like Figure 2 , Figure 3 As shown, during the construction of the anchor 8, corresponding to the anchor installation position of each cable, an anchor rod 9 is pre-buried in the anchor concrete, and corresponding to the main load-bearing cable anchor with high force requirements, an anchor cable 10 is also constructed according to the designed force requirements. After the anchor construction is completed, the anchor seat of the utility model is installed at the designed installation position of each anchor seat, and each anchor seat is anchored with the preset anchor rod 9 on the anchor through the anchor rod through hole 5, and the front end of the preset anchor cable 10 is passed through the anchor cable through hole 2 on the corresponding anchor seat and anchored with the anchor seat; after all anchor seats are installed, a pin rod 11 is inserted into the pin rod insertion hole of each anchor seat, and the diameter of the pin rod is preferably consistent with the diameter of the pin rod insertion hole to prevent the pin rod from moving horizontally in the pin rod insertion hole. Finally, the guide wheel 12 is installed through the pin shaft through hole on each anchor seat ear plate, and the cable is connected through the guide wheel.

[0012] In the above structure, the main load-bearing cable anchor seat with the highest force requirement is not only anchored by the anchor cable 10, but also anchored by the anchor rod 9 compared with the conventional anchor seat, and the force bearing capacity is also increased accordingly; while the anchor seat with lower force requirement is only anchored by the anchor rod 9, which can save the anchor cable construction cost. During the operation of the cable crane, the force of each anchor seat can be transmitted to other anchor seats through the pin rod 11, and each anchor seat is subjected to force together, which can ensure the force requirement of each cable.
