Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction and relates to a landscape elevator attached to a main tower of a suspension bridge. Background Art

[0002] Mountainous and canyon areas are famous for their beautiful and unique natural scenery. Suspension bridges mainly consist of two key structures: the bridge deck and the main tower. The main tower is usually the tallest building in the area, making it an excellent perspective for enjoying the natural scenery. With the rise of the concept of tourism resource development, the main tower of the suspension bridge has been given a new mission of tourism in addition to its transportation function. Therefore, attaching a landscape elevator to the main tower has become a new design consideration, aiming to provide tourists with a more convenient way to view the scenery. At the same time, it also provides convenient conditions for bridge maintenance operations, further enhancing the development value of the suspension bridge as an industrial tourism resource.

[0003] In the design and construction practice of the landscape elevator attached to the main tower of the suspension bridge, many difficult problems were encountered. Due to the structural characteristics and force requirements of the main tower of the suspension bridge, its outer side is not completely vertical, and often presents a certain inclination angle or curve shape. When the landscape elevator is installed to the top of the main tower, the attachment rod used to connect the elevator car and the outer side of the main tower to provide support and guidance will gradually increase in length as the height rises. This overly long attachment rod causes a series of problems. First of all, in terms of stability, its own rigidity is relatively low. Under the action of external forces such as strong and irregular wind in the canyon area and vibration during the operation of the elevator, it is very easy to bend and deform, thereby greatly increasing the risk of instability of the entire elevator system and seriously threatening the lives of tourists. Secondly, in the construction process, the long attachment rod has extremely high requirements for installation accuracy. Its transportation, hoisting, and connection with the main tower and elevator car become extremely complicated and difficult, which undoubtedly requires a lot of manpower, material resources and time costs, and also greatly increases the safety hazards in the construction process. In addition, the special climate environment in the canyon area, such as strong winds, causes the overly long attachment rods to have a larger amplitude. Long-term vibrations can easily cause fatigue problems, posing a huge challenge to the durability of the attachment rods.

[0004] At present, there are mainly the following solutions to the above problems: using an attachment rod system with adjustable length, such as setting a telescopic device or a connection node on the attachment rod, and controlling the telescopic joint through a hydraulic system to adapt to the actual shape of the outer side of the main tower and the installation position of the elevator. The advantage of this method is that the length of the attachment rod can be adjusted more flexibly within a certain range, which effectively improves the convenience during the installation process and can better adapt to the complex changes of the outer side of the main tower. However, it also has obvious disadvantages. The adjustable structure significantly increases the complexity of the entire system and significantly increases the cost. At the same time, the hydraulic device needs regular professional maintenance, otherwise it is very easy to malfunction. In addition, during long-term use, the sealing performance of the telescopic joint is difficult to guarantee and is prone to decline, which in turn affects the stability and reliability of the entire system. Taking into account the specific requirements of the landscape elevator attached to the main tower of the suspension bridge in actual production and use, such as safety, reliability, durability, cost control and other factors, the present invention proposes a multi-section attachment rod, aiming to overcome the problems of high stability risk, great construction difficulty and insufficient durability in the prior art, so as to ensure that the landscape elevator attached to the main tower of the suspension bridge can operate safely, stably and efficiently, while minimizing the adverse effects on the natural scenery, and realizing the harmonious coexistence of engineering construction and tourism resource development. Summary of the invention

[0005] The present invention provides a sightseeing elevator attached to the main tower of a suspension bridge, which solves the problem that in the design and construction of the sightseeing elevator attached to the main tower of a suspension bridge, the bridge structure is fully utilized. Because the outer side of the main tower is not vertical, the length of the attachment rod after the elevator reaches the top becomes longer, thereby increasing the stability risk and the construction difficulty, thereby realizing the problem of bridge-tour integration and symbiosis.

[0006] In order to solve the above problems, the technical solution adopted by the invention is:

[0007] A sightseeing elevator is attached to the main tower of a suspension bridge, comprising an observation deck and a sightseeing elevator arranged on the top of the main tower of the suspension bridge, wherein the sightseeing elevator comprises a frame structure, an outer facade arranged on the frame structure, a car arranged in the frame, and a driving structure for driving the car to rise and fall, wherein the frame structure is fixed to the outer facade of the main tower of the suspension bridge facing outward through an attachment rod, and a passage connecting the observation deck and the frame structure of the sightseeing elevator is arranged on the top of the suspension bridge; the attachment rod is a multi-section attachment rod, and the attachment rods are fixedly connected through a connecting piece.

[0008] The principle of this scheme is to attach the sightseeing elevator to the outer facade of the main tower of the suspension bridge, making full use of the structural support of the main tower. The attachment rod can firmly fix the frame structure on the main tower to ensure the stability and safety of the elevator during operation. The frame structure provides a solid installation foundation for the facade, car and drive structure. The facade not only plays an aesthetic role, but also provides certain protection for the internal structure and the car. The drive structure provides power for the lifting and lowering of the car through electricity or other power sources. Its working principle is similar to that of the common vertical elevator drive system, which can accurately control the rising and falling speed and position of the car. The observation deck set on the top of the main tower of the suspension bridge is connected to the frame structure of the sightseeing elevator through a channel, so that tourists can easily enter the elevator from the observation deck, or reach the observation deck from the elevator. The design of the entire system is to provide tourists with a unique sightseeing experience without affecting the structural performance and safety of the main tower of the suspension bridge.

[0009] The beneficial effects of this program:

[0010] From the perspective of tourism experience, the installation of the sightseeing elevator attached to the main tower of the suspension bridge has greatly enriched the sightseeing options of tourists. The observation deck on the top of the main tower provides tourists with a higher perspective to appreciate the scenery. Tourists on the sightseeing elevator can appreciate the beauty of the suspension bridge and the surrounding scenery from all directions and angles, which greatly enhances the fun and attraction of tourism. In addition, the plan fully exploits the utilization rate of existing building facilities and avoids more damage to natural resources caused by the construction of a new observation deck.

[0011] Secondly, the main tower of the suspension bridge is a super-high building. In the existing technology, dampers are usually installed on the building when installing elevators on super-high buildings. However, the top of the main tower of the suspension bridge is under thousands of tons of pressure, and its stability is higher than that of ordinary super-high buildings. This provides favorable conditions for installing elevators on the side of the main tower of the suspension bridge.

[0012] The addition of a sightseeing elevator is not just for sightseeing. In emergency situations, such as when the main tower or other parts of the bridge need to be repaired or rescued, the elevator can serve as a fast and safe transportation channel, improving the emergency response capability and maintenance efficiency of the bridge facilities.

[0013] The multi-section attachment rods are fixedly connected by connecting parts, which effectively solves the installation problems caused by the irregular shape and inclination of the main tower side. The multi-section connection method not only improves the convenience and efficiency of construction, but also makes full use of the suspension bridge structure. There is no need to install wind dampers, which also reduces project costs. During the installation process, the hoisting is light, the safety is good, and the construction is convenient.

[0014] At the same time, the elevator installed in the outer side space of the main tower does not occupy the traffic space on the bridge deck, does not interfere with the traffic function of the suspension bridge, and provides tourists with a convenient vertical transportation method, allowing them to easily reach the viewing platform area of ​​the main tower.

[0015] Furthermore, a cable strand is arranged on the top of the main tower, which extends through the top of the main tower to the main tower on the river bank, and the other end of the cable strand is fixed on the anchor. The cable strand arranged on the top of the main tower connects the main tower with the main tower on the river bank and the anchor, forming a stable force-bearing system. The cable strand can effectively share the load borne by the main tower, including the dynamic load generated when the elevator is running, as well as natural forces such as wind load and earthquake load, thereby enhancing the stability and seismic resistance of the entire main tower structure and ensuring the safety of the main tower and the landscape elevator attached thereto.

[0016] Furthermore, embedded parts are provided on the outer side surface of the main tower, and the embedded parts are fixedly connected to the attachment rods by bolts. In terms of installation and maintenance, the embedded parts and the attachment rods are fixedly connected by bolts, which makes the installation process simpler and faster. Construction workers can quickly assemble them on site, thereby improving construction efficiency and shortening the project period.

[0017] Furthermore, an arc-shaped transparent glass cover is provided on one side of the frame structure away from the outer side of the main tower and on two adjacent sides. A wind sensor is provided on the glass cover. The wind sensor is arranged at the top end of the arc. Setting the wind sensor at the top end of the arc-shaped transparent glass cover can more accurately detect the wind direction and wind speed. Since the position is relatively high and prominent, the wind is less disturbed when flowing through here. The detected data can better reflect the actual wind conditions, providing a more accurate basis for the operation control and safety assurance of the elevator. When it is detected that the wind speed exceeds the safety threshold, the elevator control system can take corresponding measures in time, such as suspending operation or reducing the operating speed, thereby effectively avoiding elevator shaking or other safety problems caused by strong winds and ensuring the safety of passengers.

[0018] Furthermore, a pull rod is provided at the lower end of the attachment rod, one end of the pull rod is hinged on the embedded part, and the other end is hinged on the frame structure. A tension damper is provided at the middle position of the pull rod, and the tension damper is electrically connected to the wind sensor. The pull rod arranged at the lower end of the attachment rod and the tension damper in the middle form an additional support and buffer structure. The hinged connection mode of the pull rod enables it to flexibly adapt to the relative displacement between the main tower, the embedded part and the frame structure, and effectively share the tension borne by the attachment rod, thereby enhancing the stability and reliability of the entire connection structure. When the wind sensor detects strong wind, it can promptly transmit the signal to the tension damper. The tension damper can adjust the damping force in real time according to the intensity and change of the wind, effectively absorb and reduce the vibration energy generated by the wind load on the structure, reduce the adverse effects of wind-induced vibration on the elevator and the main tower structure, and ensure the safe operation of the elevator in windy weather. The electrical connection between the wind sensor and the tension damper realizes automatic adjustment of the structural response. Without human intervention, the system can automatically optimize the damping effect according to real-time wind conditions, improving the structure's adaptability and intelligence level and reducing wind interference with the elevator.

[0019] Furthermore, a traction system is provided at the top and bottom of the main tower, and the traction system is fixedly connected to the top and bottom of the sightseeing elevator. The traction systems are electrically connected, and the traction systems provided at the top and bottom of the main tower are fixedly connected to the top and bottom of the sightseeing elevator. The sightseeing elevator is tightened by the traction system to prevent the sightseeing elevator from shaking and ensure safety.

[0020] Furthermore, the traction systems at the upper and lower ends of the main tower are connected to the sightseeing elevator through steel cables to form a triangular structure. The traction systems at the upper and lower ends of the main tower are connected to the sightseeing elevator through steel cables to form a triangle, which can effectively disperse and withstand forces from all directions. When wind acts on the elevator, the triangular layout can reduce wind resistance, reduce the impact of wind on elevator operation, reduce wind-induced vibration and shaking, and further improve the operating stability and safety of the elevator under severe weather conditions.

[0021] Furthermore, the traction system is a traction machine, which is electrically connected to a wind sensor. When the wind sensor detects a change in wind speed, it can promptly transmit a signal to the control system of the traction machine. The traction machine can adjust the traction force and speed in real time according to the intensity and changes of the wind, thereby better adapting to different wind conditions and ensuring the stability and safety of the elevator operation.

[0022] Furthermore, a traction machine is arranged on the top of the frame structure, and the sightseeing elevator is vertically pulled by the traction machine.

[0023] Furthermore, the traction systems at the top and bottom of the main tower work together, one performs the traction action, and the other performs the cable loosening action. Through the execution of the coordinated work of the traction systems, the sightseeing elevator is fitted into the frame structure close to the side of the main tower through the traction system. Through the support of the attachment rod and the coordination of the two traction systems, the swing of the sightseeing elevator is reduced, thereby improving the safety of the sightseeing elevator.
