Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a cable connection device. Background Art

[0002] At present, my country is still in the process of rapid development of transportation infrastructure construction. In particular, in recent years, steel tube concrete arch bridges have become more and more popular due to their high strength, fatigue resistance, impact resistance, and beautiful appearance. When building steel tube concrete arch bridges, the inclined stay buckle hanging method is often used for construction. Because the inclined stay buckle hanging method has wide adaptability and easy construction operation, it has become the most commonly used and effective construction method for large-span steel tube concrete arch bridges.

[0003] The currently used inclined-stayed buckle-hanging system mainly consists of a buckle tower, a jack, a buckle saddle and a steel strand buckle as the buckle-hanging system. The arch rib buckle point is a key link in the construction of the inclined-stayed buckle-hanging method. The quality of the arch rib buckle point design will directly affect the force of the entire inclined-stayed buckle-hanging system, and will seriously lead to safety accidents. In the prior art, the arch rib buckle point is generally set below the arch rib, and the installation of the buckle cable is time-consuming, the operation is cumbersome, and the connection safety is difficult to ensure. The existing patent technology CN201529759661.2 provides a buckle cable connector, which directly uses the existing connection bolt holes to realize the connection between the anchor cable system and the main arch component, and sets a number of bolt hole groups on the two main bearing plates. However, the processing accuracy of the buckle cable connector is high, and during the installation process, the bolt hole group on the arch column support on the main arch component has high installation requirements, so that high-strength bolts can be used for connection. In addition, since the cable hole is long, it has a strong restrictive effect on the cable. During the actual construction process, the cable is easily squeezed or rubbed against the edge of the cable hole when shaking or rotating, which has an adverse effect on the cable connector or the cable. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies of the existing buckle cable connector, the technical problem to be solved by the utility model is to provide a buckle cable connecting device with better stability and adaptability.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A buckle cable connecting device comprises a connecting seat and a buckle cable connected to the connecting seat, the connecting seat comprises a left side plate, a right side plate, a load-bearing plate and a pin shaft, the load-bearing plate is connected and arranged between the middle and upper parts of the left side plate and the right side plate, a stiffening plate is arranged between the upper surface of the load-bearing plate and the left side plate and the right side plate, a through hole is arranged in the middle of the load-bearing plate for the buckle cable to pass through and be fixed, the left side plate and the right side plate are both provided with a pin shaft hole at one end away from the stiffening plate, the pin shaft is used to connect the lifting ear of the steel pipe arch rib with the pin shaft hole, so as to realize the connection between the connecting seat and the steel pipe arch rib.

[0007] Furthermore, the left and right sides of the load-bearing plate are respectively connected to the left side plate and the right side plate through at least two spaced-apart stiffening plates.

[0008] Furthermore, the upper end of the stiffening plate is flush with the upper ends of the left plate and the right plate, and the width of the upper end of the stiffening plate is smaller than the width of the lower end.

[0009] Furthermore, connecting plates are provided on the two side edges of the upper surface of the load-bearing plate that are perpendicular to the left and right plates, and the load-bearing plate, the connecting plates, the left and right plates form a box-type structure with an open top.

[0010] Furthermore, a reinforcing plate is provided on the lower surface of the load-bearing plate, and the through holes on the load-bearing plate penetrate the reinforcing plate.

[0011] The beneficial effects of the utility model are as follows: the load-bearing plate is used to fix the buckle cable, and the stiffening plate on the top of the load-bearing plate is used to increase the connection strength between the load-bearing plate and the left plate and the right plate, thereby ensuring the reliability of the connection between the buckle cable and the connecting seat; since the through hole on the load-bearing plate is relatively short, the shaking or rotation of the buckle cable is less affected, and no damage is caused to the connecting seat or the buckle cable; in addition, the connecting seat is connected to the lifting ear of the steel pipe arch rib by a pin shaft, which does not require high processing and installation precision, and can improve the installation efficiency of the entire cable lifting system.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0018] like Figure 1-3 As shown, the buckle cable connecting device of the utility model includes a connecting seat and a buckle cable 6 connected to the connecting seat, the connecting seat includes a left side plate 1, a right side plate 2, a load-bearing plate 3 and a pin 4, the load-bearing plate 3 is connected and arranged between the middle and upper parts of the left side plate 1 and the right side plate 2, a stiffening plate 5 is provided between the upper surface of the load-bearing plate 3 and the left side plate 1 and the right side plate 2, a through hole 31 is provided in the middle of the load-bearing plate 3 for the buckle cable 6 to pass through and be fixed, the left side plate 1 and the right side plate 2 are both provided with a pin hole 11 at one end away from the stiffening plate 5, the pin 4 is used to connect the lifting ear of the steel pipe arch rib 7 with the pin hole 11, so as to realize the connection between the connecting seat and the steel pipe arch rib 7.

[0019] The utility model mainly uses the bearing plate 3 to bear the tension of the buckle cable 6. The stiffening plate 5 is arranged between the upper surface of the bearing plate 3 and the left plate 1 and the right plate 2, which can support the bearing plate 3, thereby well resisting the tension of the buckle cable 6. Since the through hole 31 on the bearing plate 3 is short, it has little effect on the shaking or rotation of the buckle cable 6. There is enough space above the bearing plate 3 for the buckle cable 6 to move, and the connecting seat or the buckle cable will not be squeezed, deformed or damaged during the construction process. In addition, the connecting seat of the utility model is connected to the lifting ear of the steel pipe arch rib 7 through the pin shaft 4. The connection is convenient and reliable, does not require high processing and installation precision, and can improve the installation efficiency of the entire cable hoisting system.

[0020] In order to improve the supporting effect of the stiffening plate 5 on the load-bearing plate 3, the left and right sides of the load-bearing plate 3 are respectively connected to the left side plate 1 and the right side plate 2 through at least two spaced stiffening plates 5. In order to make the force uniform, the stiffening plates 5 on the same side are symmetrically arranged with the axis of the length direction of the load-bearing plate 3 as the symmetry axis, and the stiffening plates 5 on both sides are symmetrically arranged with the axis of the width direction of the load-bearing plate 3 as the symmetry axis.

[0021] As for the specific shape of the stiffening plate 5, in order to improve the integrity of the structure, the upper end of the stiffening plate 5 is flush with the upper ends of the left plate 1 and the right plate 2. In order to leave more space at the top, the width of the upper end of the stiffening plate 5 can be set to be smaller than the width of the lower end, so as to leave a conical space at the top for the buckle cable 6 to move.

[0022] In order to further increase the overall strength of the connection seat, a connection plate 8 is further provided on the two sides of the upper surface of the load-bearing plate 3 that are perpendicular to the left side plate 1 and the right side plate 2. The load-bearing plate 3 and the connection plate 8, the left side plate 1 and the right side plate 2 form a box-shaped structure with an open top. This can increase the structural strength of the connection seat, enabling it to withstand the pulling force of the buckle cable 6 from all directions, thereby reducing the deformation of the left side plate 1 and the right side plate 2.

[0023] In order to prevent the through hole 31 on the load-bearing plate 3 from being deformed due to the tension of the buckle cable 6, a reinforcing plate 9 is provided on the lower surface of the load-bearing plate 3, and the through hole 31 on the load-bearing plate 3 passes through the reinforcing plate 9. The reinforcing plate 9 is fixed to the load-bearing plate 3 by welding, which can increase the stability of its connection with the buckle cable 6.

[0024] In summary, the utility model utilizes the load-bearing plate 3 to fix the buckle cable 6, and increases the connection strength between the load-bearing plate 3 and the left plate 1 and the right plate 2 through the stiffening plate 5 on the top of the load-bearing plate 3, thereby ensuring the reliability of the connection between the buckle cable 6 and the connecting seat. Since the through hole 31 on the load-bearing plate 3 is relatively short, the shaking or rotation of the buckle cable 6 is less affected, and there is sufficient activity space above the load-bearing plate 3, and no damage is caused to the connecting seat or the buckle cable 6. In addition, the connecting seat is connected to the lifting ear of the steel pipe arch rib 7 through the pin shaft 4, which does not require high processing and installation precision, can improve the installation efficiency of the entire cable lifting system, and has good practicality and application prospects.
