Description

Technical Field

[0001] The present invention belongs to the technical field of bridges, and more specifically, relates to a guiding device, an opening bridge and an installation method for a vertically lifting opening bridge. Background Art

[0002] A vertically lifting opening bridge is a special type of bridge structure. Its main girder can be lifted and opened like an elevator to balance the needs of waterway and land transportation. When the main girder is lifted, ships can pass under the bridge; when the main girder is lowered, vehicles can pass on the bridge.

[0003] Generally, a vertically lifting opening bridge is provided with tower columns, and a hoist is arranged at the top of the tower. The hoist is connected to the main girder through a steel wire rope, and the guiding device plays a role of directional guiding and maintaining stability when the main girder is lifted and lowered. The guiding device generally adopts a structure type in which a slider (or a pulley, the same below) cooperates with a track, that is, a slider is installed on the main girder, a track is installed on the tower column, and when the main girder is lifted and lowered, the slider moves along the track.

[0004] This type of guiding device has certain disadvantages: First, its adaptability to temperature changes is poor - when the ambient temperature changes, the main girder, as a planar structure, will expand and contract in the horizontal plane, while the tower column, as a high-rise structure, will basically not expand and contract in the horizontal plane. Then, the relative position between the slider and the track will also change continuously with the temperature, and their cooperation degree is very poor, which is easy to cause jamming or damage, especially for long-span bridges. Second, its adaptability to external force is poor - similar to the change of ambient temperature, under the action of external forces such as wind load, the main girder will swing during the lifting and lowering process, and the slider and the track cannot adapt to the swing of the main girder, and the same jamming or damage will occur. Third, the contact form between the slider and the track is a hard contact without buffering, and under the action of the above temperature and external forces, the two gradually deviate and deform, resulting in a large noise and poor durability of the guiding device. Summary of the Invention

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "the" and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0048] Embodiment 1

[0049] Aiming at the problems of poor performance, high noise and poor durability of the conventional guiding device of the existing vertical lifting opening bridge, Embodiment 1 of the present invention provides a guiding device for a vertical lifting opening bridge, as Figures 1-7 shown, including: two spring-damper pulley groups 1, a vertical connecting rod 3 and a horizontal connecting rod 4. Each spring-damper pulley group 1 includes a long axis 1.1, a short axis 1.2 and three spring-damper pulleys 1.3. One end of the short axis 1.2 is connected to the midpoint of the long axis 1.1, and the three spring-damper pulleys 1.3 are respectively connected to both ends of the long axis 1.1 and one end of the short axis 1.2; each spring-damper pulley 1.3 includes a pulley 1.3.1, a spring 1.3.2 and a damper 1.3.3 which are connected to each other; both ends of the vertical connecting rod 3 are respectively connected to the two spring-damper pulley groups 1; one end of the horizontal connecting rod 4 is connected to the spring-damper pulley group 1, and the other end is used to connect the main girder 6 of the vertical lifting opening bridge.

[0050] In this embodiment, the spring-damper pulley group 1 is an assembly, including a long shaft 1.1 and a short shaft 1.2 extending from the midpoint of the long shaft 1.1 and perpendicular to the long shaft 1.1. Both ends of the long shaft 1.1 are connected to spring-damper pulleys 1.3, and the outer ends of the short shaft 1.2 are connected to spring-damper pulleys 1.3. That is, a spring-damper pulley group 1 includes three spring-damper pulleys 1.3, and a spring-damper pulley 1.3 includes a pulley 1.3.1, a spring 1.3.2, and a damper 1.3.3. The spring 1.3.2 can be a helical spring or an air spring, and the damper 1.3.3 can be a hydraulic damper or an electromagnetic damper.

[0051] When the guiding device of a vertically-lifting opening bridge according to an embodiment of the present invention is in use, the guiding device is installed in the tower column grooves on both sides of the bridge, and the vertically-lifting opening bridge is guided by the up-and-down sliding of the spring-damper pulley group 1 in the tower column grooves. There is no need to set tracks. The guiding device contacts the tower column through the pulley 1.3.1, and the frictional resistance of the contact surface is extremely small, which can ensure a smooth lifting process. The guiding device according to the embodiment of the present invention relies on the reset and buffering functions provided by the spring 1.3.2 and the damping function provided by the damper 1.3.3, so that the guiding device has extremely strong adaptability to environmental temperature changes and external forces. When the main beam 6 of the vertically-lifting opening bridge undergoes temperature expansion and contraction or wind-induced swing, the dimensions of the long shaft 1.1 and the short shaft 1.2 of the guiding device will change accordingly, and the damper 1.3.3 ensures the smoothness and silence of the dimension change process of the guiding device, while the spring 1.3.2 will reset the dimensions of the guiding device after the external environment stabilizes. Therefore, the guiding device according to the embodiment of the present invention ensures that the main beam 6 of the vertically-lifting opening bridge will not get stuck or damaged during the lifting process, greatly improving the durability, and having the functions of reset, buffering, and damping, and can realize the safe, stable, and silent opening of the opening bridge.

[0052] Further, in one embodiment, the spring 1.3.2 is sleeved on the telescopic rod of the damper 1.3.3. Both ends of the spring 1.3.2 are fixedly connected to the pulley 1.3.1 and the damper 1.3.3 respectively. The pulley 1.3.1 is connected to one end of the telescopic rod of the damper 1.3.3. The two dampers 1.3.3 located at both ends of the long shaft 1.1 are connected to the long shaft 1.1, and one damper 1.3.3 located at one end of the short shaft 1.2 is connected to the short shaft 1.2, as Figures 3-5As shown. A break end cover can also be fixedly connected to the telescopic rod of the damper 1.3.3. The pulley 1.3.1 is connected to one side of the end cover. One end of the spring 1.3.2 is fixedly connected to the other side of the end cover, and the other end is fixedly connected to the outer shell of the damper 1.3.3. It should be noted that the connection relationship between the pulley 1.3.1, the spring 1.3.2 and the damper 1.3.3 in each spring-damper pulley 1.3 is not limited to this. As long as the spring 1.3.2 can provide a reset and buffering function and the damper 1.3.3 can provide a vibration damping function after each spring-damper pulley 1.3 is connected.

[0053] Further, in one embodiment, there are two vertical connecting rods 3 symmetrically arranged. Each vertical connecting rod 3 is connected to two spring-damper pulley groups 1 through two node plates 2. Each node plate 2 is connected to a horizontal connecting rod 4, as Figure 1 、 Figure 2 shown. Furthermore, each node plate 2 is connected to the long axis 1.1 or the damper 1.3.3. In this embodiment, each node plate 2 is connected to the damper 1.3.3. The two vertical connecting rods 3 are symmetrically arranged on both sides of the short axis 1.2, that is, the node plate 2 serves as the intersection node between the damper 1.3.3, the vertical connecting rod 3 and the horizontal connecting rod 4, connecting the three into a whole. One set of spring-damper pulley group 1 is configured with two node plates 2. The vertical connecting rod 3 of this embodiment is arranged in the vertical plane and connects two sets of spring-damper pulley groups 1 through the node plate 2. After the two sets of spring-damper pulley groups 1 are assembled through the vertical connecting rod 3, a stable frame structure is formed. The horizontal connecting rod 4 is arranged in the horizontal plane and connects the spring-damper pulley group 1 and the main beam 6 through the node plate 2. After the horizontal connecting rod 4 is connected, the spring-damper pulley group 1 is completely fixed to the main beam 6 of the vertical lifting opening bridge.

[0054] Further, in one embodiment, each node plate 2 is pin-connected to the vertical connecting rod 3 and the horizontal connecting rod 4. Pin connection is easy to disassemble, facilitating the rapid assembly of each component on site and avoiding the method of transporting large parts to the site after overall installation in the factory.

[0055] Embodiment 2

[0056] Embodiment 2 of the present invention provides a vertical lifting opening bridge, the structure of which is as Figures 8-12As shown in the figure, it includes: a main beam 6, four tower columns 5, at least two guiding devices described in Embodiment 1, and a plurality of hoists 8. A plurality of suspension points 9 for connecting steel wire ropes 7 are provided on the main beam 6; the four tower columns 5 are symmetrically arranged on both sides of the main beam 6; a groove is provided on one side of each tower column 5 facing the main beam 6; each guiding device is arranged in the groove of the tower column 5, and the three pulleys 1.3.1 of each guiding device are in contact with the inner wall of the groove of the tower column 5, and the horizontal connecting rod 4 of each guiding device is connected to the main beam 6, and the horizontal connecting rod 4 and the main beam 6 can be welded; a plurality of hoists 8 are connected to the suspension points 9 of the main beam 6 through steel wire ropes 7 for vertically lifting the main beam 6.

[0057] The working principle of a vertically lifting and opening bridge according to an embodiment of the present invention is as follows: Four suspension points 9 are symmetrically arranged on both sides of the main beam 6 of the vertically lifting and opening bridge. Tower columns 5 are provided at each suspension point 9, and hoists 8 are arranged at the top of the towers. The hoists 8 are connected to the main beam 6 through steel wire ropes 7. In addition, a groove is provided in the cross-section of the tower column as the moving channel for the suspension points 9 of the main beam 6 and the steel wire ropes 7, and the guiding device is installed in this groove. After installing the guiding device at each suspension point 9 of the main beam 6 (theoretically, installing only at any two diagonally opposite suspension points 9 can ensure the effect, but the effect is better when installed at each suspension point 9), the horizontal relative displacement between the main beam 6 and the tower column 5 is restricted, but the vertical relative displacement is not restricted. Then, the guiding device can realize the basic guiding function during the lifting and lowering process of the main beam 6. At the same time, the guiding device contacts the tower column 5 with pulleys 1.3.1, and the frictional resistance of the contact surface is extremely small, which can ensure the smoothness of the lifting and lowering process. In addition, relying on the reset and buffering functions provided by the spring 1.3.2 and the vibration damping function provided by the damper 1.3.3, the guiding device has strong adaptability to environmental temperature changes and external forces. When the main beam 6 undergoes temperature expansion and contraction or wind load swing, it can be lifted and lowered safely, stably, and quietly.

[0058] After installing the guiding device according to an embodiment of the present invention on a vertically lifting and opening bridge, on the basis of having the basic guiding function of a conventional guiding device, the track is cancelled, which ensures that the main beam 6 of the vertically lifting and opening bridge will not get stuck or damaged during the lifting and lowering process, greatly improving the durability, and having the reset, buffering, and vibration damping functions, and can realize the safe, stable, and quiet opening of the opening bridge.

[0059] Embodiment 3

[0060] Embodiment 3 of the present invention provides an installation method for a vertically lifting and opening bridge, including the following steps:

[0061] S1. As Figure 5 , pre-assemble the spring-damper pulley group 1 in the factory;

[0062] Specifically, multiple sets of spring-damping pulley groups 1 and gusset plates 2 are pre-assembled and formed in the factory and then transported to the site. During the in-factory manufacturing, the dimensions of the long shaft 1.1 and the short shaft 1.2 of the spring-damping pulley group 1 should be slightly larger than the theoretical dimensions matching the grooves of the tower column 5, so that after subsequent installation, the springs 1.3.2 are all in a compressed state (when installing, it is necessary to apply compression to shorten the dimensions of the long shaft 1.1 and the short shaft 1.2 of the springs 1.3.2). Then, the restoring force of the springs 1.3.2 will keep the pulleys 1.3.1 always tightly attached to the inner wall of the grooves of the tower column 5, achieving an ideal working state;

[0063] S2. As shown in Figure 2 , assemble two spring-damping pulley groups 1 into a stable guiding frame through the vertical connecting rod 3;

[0064] S3. As shown in Figure 10 , apply pressure to the springs 1.3.2 in the direction of the long shaft 1.1 of the spring-damping pulley group 1, so that after the springs 1.3.2 are compressed, the guiding frame is installed into the grooves of the tower column 5;

[0065] S4. As shown in Figure 11 , apply pressure to the springs 1.3.2 in the direction of the short shaft 1.2 of the spring-damping pulley group 1, so that after the springs 1.3.2 are compressed, connect the horizontal connecting rod 4 of the spring-damping pulley group 1 to the main beam 6, and the three pulleys 1.3.1 of each spring-damping pulley group 1 are all in contact with the inner wall of the groove, completing the installation of one guiding device;

[0066] Repeat S1 - S4 to complete the installation of the guiding devices at other lifting points 9 of the main beam 6; generally, lifting points 9 are provided at the four corner points of the main beam 6. Theoretically, only symmetrically installing two guiding devices at any two diagonally opposite lifting points 9 can ensure the effect, but at the four lifting points 9, that is, symmetrically installing four guiding devices on both sides of the main beam 6 has a better effect;

[0067] S5. Connect the steel wire ropes 7 of the winches 8 to the multiple lifting points 9 on the main beam 6 of the vertical lifting and opening bridge to complete the installation of the vertical lifting and opening bridge.

[0068] After installing the guiding device at each hanging point 9 of the main beam 6 in the installation method of the embodiment of the present invention, the horizontal relative displacement between the main beam 6 and the tower column 5 is restricted, but the vertical relative displacement is not restricted. Then, the guiding device can achieve the basic guiding function during the lifting process of the main beam 6. The guiding device contacts the tower column 5 with pulleys 1.3.1, and the frictional resistance of the contact surface is extremely small, which can ensure the smoothness of the lifting process. During the lifting process, relying on the reset and buffering functions provided by the spring 1.3.2 and the vibration damping function provided by the damper 1.3.3, the guiding device has extremely strong adaptability to environmental temperature changes and external forces. When the main beam 6 undergoes thermal expansion and contraction or wind-induced swing, the dimensions of the long axis 1.1 and the short axis 1.2 of the guiding device will change accordingly. The damper 1.3.3 ensures the smoothness and quietness of the dimension change process of the guiding device, and the spring 1.3.2 will reset the dimensions of the guiding device after the external environment stabilizes. Finally, the guiding device ensures the safe, stable, and quiet lifting of the main beam 6.

[0069] The installation method of a vertically lifting and opening bridge in the embodiment of the present invention has simple steps, and after installation, the safe, stable, and quiet opening of the opening bridge can be achieved.

[0070] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
