Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a temporary rope-pulling rope hanging basket. Background Art

[0002] Hanging basket construction, also known as construction hanging basket, is a major equipment for the segmented construction of prestressed concrete continuous beams, T-shaped steel structures and cantilever beams. It can move forward as a whole along the track. Hanging basket construction can use: truss hanging basket, triangular hanging basket, prismatic hanging basket and cable-stayed hanging basket and other processes. It is most widely used in bridge construction. In the existing technology, most of the ways to fix the hanging basket on the bridge use permanent cables, but the use of permanent cables is only limited to the cable-stayed construction of bridges with a width of less than 30m. If the width is larger, it will lead to a decrease in the fixation and stability of the permanent cables on the hanging basket. Therefore, a better way is needed to replace the permanent cables to connect and fix the hanging basket to improve the stability of the system and the safety of construction.

[0003] Therefore, in view of the above-mentioned problems, a temporary rope-pulling rope hanging basket is designed in a targeted manner. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides a temporary cable pulling rope basket, comprising: an anchoring system, a cable hanging basket, a temporary cable and a winch, the anchoring system is fixedly connected to the bridge deck, the cable hanging basket is arranged below the bridge deck and passes through the bridge deck to be connected to the anchoring system, one end of the temporary cable is connected to the front end of the anchoring system, and the other end of the temporary cable is connected to the winch at the top of the bridge tower.

[0006] In the above manner, the guy wire basket is fixed under the bridge deck through the anchoring system. The temporary cable can fix the guy wire basket by tightening the anchoring system. The other end of the temporary cable is connected to the winch on the top of the bridge tower. The length of the temporary cable can be adjusted to adapt to the position of the guy wire basket after it moves, so as to continue to fix the guy wire basket.

[0007] Furthermore, the anchoring system includes a main longitudinal beam, an upper cross beam and a fastening device, wherein there are two main longitudinal beams which are parallel to each other, one end of the main longitudinal beam is fixedly connected to the bridge deck via a fastening device, the other end of the main longitudinal beam extends out of the bridge deck and is connected to the hanging basket via the fastening device, and the upper cross beam is fixedly connected between the two main longitudinal beams and is located at the end of the main longitudinal beam.

[0008] In the above manner, the upper cross beam between the two main longitudinal beams is a fixed fulcrum for the temporary cable. The length of the upper cross beam is greater than the length of the permanent cable fixed between the upper fulcrums of the guying basket in the prior art, which can provide better stability and safety.

[0009] Furthermore, the guy wire hanging basket comprises: a lower cross beam, a template and hanging legs, the two ends of the lower cross beam are fixedly connected with the hanging legs, the template support is arranged on the upper part of the lower cross beam, and the main longitudinal beam is connected to the lower cross beam through the fastening device. The template is used for supporting and shaping the bridge casting.

[0010] Furthermore, the temporary cable is connected to the upper cross beam via a bottom fixing device.

[0011] Furthermore, the fastening device includes an anchor beam and a steel rod screw, the anchor beam is arranged on the main longitudinal beam, and the steel rod screw passes through the anchor beam and is connected to the hanging basket.

[0012] Furthermore, the bottom fixing device includes a double-ear plate base, a double-pin ear plate, a fork ear, a long pin shaft and a short pin shaft, the double-ear plate base is fixedly connected to the two ends of the upper crossbeam, the double-pin ear plate is connected to the double-ear plate base through the long pin shaft, the fork ear is connected to the double-pin ear plate through the short pin shaft, and the temporary cable is connected to the fork ear. In the above manner, the bottom fixing structure is a universal twist structure, which can provide more degrees of freedom when adjusting the temporary cable.

[0013] Furthermore, the lower cross beam is provided with a protruding connection block, the connection block is located at the front end of the lower cross beam, and the front end of the main longitudinal beam is connected to the connection block through the fastening device. The protruding connection block can more effectively improve the connection stability between the temporary cable and the lower cross beam.

[0014] In summary, the utility model has the following advantages and beneficial technical effects:

[0015] 1. The upper crossbeam on the temporary rope hanging basket of the utility model provides a connection point for the temporary rope, and the upper crossbeam has a larger span, which can make the distance between the two temporary ropes larger, providing better stability and safety;

[0016] 2. The utility model uses a temporary cable-pulling hanging basket to balance the main longitudinal beam and bear the front end load of the concrete beam together with the inclined cable. The temporary cable is hung on the front end of the main beam of the hanging basket, which optimizes the force form and is similar to a double-cable hanging basket. It is easy to control the elevation deviation of the cantilever casting section and can correct the linear error of the closing section at any time to ensure the balance of the hanging basket.
