Description

The present invention relates to the field of construction, and more specifically to the construction of bridges with entertainment complexes.

A known system includes a bridge arch with a spectacular entertainment complex located in it as a building structure composition, which is a separate three-dimensional structural element connected to the supporting structure; elevator and stair shafts are mounted on each of the parts of the arch ends of the supporting structure with upper and lower platforms (see RF patent for PM No. 40058 of April 22, 2004)

The technical task of the invention is to simplify the design and increase the performance of the system.

The technical result is achieved by the fact that the system of the viewing platform (restaurant) built into the arch of the bridge contains a viewing platform (restaurant) in the form of a steel frame with glazing connected vertically with an arch by means of a metal frame rigidly fixed on the bridge pylon;

frame, made in the form of metal structures, interconnected with the possibility of forming a volumetric ellipsoid, free openings are provided with double-glazed windows with elements of sun-protection and heating;

glass transitions in the form of two spatial trusses, which are cantilever adjacent to the frame of the restaurant and rigidly connected with the arch;

lifting mechanisms for cargo and passenger cabs;

berthing stations on the lower and upper levels; ground hull for system maintenance.

At the same time, the lifting mechanisms contain a path in the form of a welded structure representing a truss of variable rectangular cross section, attached to the outer side of the inner belt of the bridge arch on cylindrical hinges, in which guides for moving the cabins and counterweight are placed, as well as mechanisms for ensuring smooth and safe operation ;

lift cabins in the form of spatial frames with suspension nodes, glazing, automatic doors, a stabilization system, a security system, electrical equipment;

cab drive mechanism, which includes a troso-block system with a drive, a movable carriage with a cab suspension assembly and a counterweight on a polyspast suspension.

The proposed construction is illustrated by drawings, where in FIG. 1 schematically shows a general view of the system of the viewing platform (restaurant) complex, built into the arch of the bridge; in fig. 2 - a general view of the observation deck (restaurant); in fig. 3 is a schematic representation of the lifting mechanism; FIG. 4 is a sectional view from above of the upper level of the viewing platform; FIG. 5 is a top view of the lower level of the viewing platform in section.

The system of the observation deck (restaurant), located in the arch of the bridge, contains the arch of the bridge 1 with the observation deck (restaurant) 2, glazed transitions 3, which cantilever adjoin the observation deck 2, lifting mechanisms in the form of paths 5 with guides 6 for moving Cabins 7, berthing stations 8 and a ground hull to service the system 9.

The proposed design operates as follows.

In order for visitors to get to the observation deck (restaurant) 2 in the arch of bridge 1, there are four lifting mechanisms (lifts) - two each on the right and on the left of the pylon 1. At the lower berth station 8, passengers are loaded into the cabin 7, pivotally mounted on a movable carriage. The carriage is driven by an electric winch. To reduce power consumption, a part of the total weight of the cab 7 and the carriage is compensated by a counterweight. The counterweight moves along the guides 6 in the same special way as the cab carriage. The path is a welded steel structure in the form of a rectangular truss, in which are placed the guides 6 for moving the cab 7 and the counterweight, the tensioner with the load, the guides for the wheels and catchers, the system of sliding contacts for powering the systems of the cabin 7, the system of supporting rollers of traction and compensating contacts . The total length of the lift path is 111 m. The path is divided into sections equal in length to the distance between the power pylon struts. Sections of the track truss are interconnected by means of bolted joints. Conventionally, the track beam is divided into two parts. One part, closed, is intended for the movement of the counterweight and its ropes, the other for the movement of the carriage and the cabin. The path is attached to the structures of the bridge on cylindrical hinges. This type of fastening ensures the independence of the structures of the lift from the deformations of the bridge pylon. The path is attached to the pylon struts. A traction winch with a system of diverting rollers installed in a special casing is installed on the same foundation. To allow installation and disassembly of the cab carriage, counterweight and winch, some of the braces and struts in the lower part of the track frame are removable. At the bottom of the track truss there is a tensioning device, which provides the necessary tension of the traction and compensating ropes. At the top of the track farm, a system of bypass blocks is installed. In the zones of the extreme positions of the carriage, counterweight and tensioner, hydraulic buffers are installed.

Power frame cab 7 is a spatial welded frame of rectangular pipes of various sections. In the upper part of the frame there is a power console with suspension nodes, through which the cabin is attached to the movable carriage. For inspection and maintenance of cable ducts on the track structures and emergency evacuation of passengers of the stopped elevator, installation of removable platforms is provided on the cab roof. Panoramic glazing cab 7 and the microclimate system allow for comfortable movement of visitors in any weather at a speed of 2 m / s. The path 5 of the lifts is installed along the inner surface of the pylon bridge 1 along the paths 6, repeating the shape of the arch of the bridge 1.

The climate system to maintain the comfort of passengers in the cabin 7 has a separate control and display panel that displays the internal temperature in the cabin 7 and the ambient temperature.

Since the movement of the carriage of the cab 7 occurs along a curved path of variable curvature, to maintain the horizontal position of the floor, the cab 7 is equipped with a stabilization system. A stabilization system is also needed to prevent the cab from swaying from wind gusts and with uneven loading. The horizontal position of the floor is ensured with an accuracy of two degrees, which is practically not felt by passengers.

All executive, command and service electrical cab devices are integrated into the electrical system. In order to ensure fire safety, all electrical circuits are made of non-flammable wires and cables. The cab security system consists of a set of control switches, a fire extinguisher, a video camera for internal surveillance, a communication system from the control room and an information plate on emergency actions.

To reduce the power of the drive winch on the lift used a counterweight. To maximize the use of the mass of the counterweight, a polyspast suspension was used, in which the path of movement of the counterweight is equal to half the path of movement of the cabin. The counterweight is made in the form of a spatial frame similar to the frame of the carriage of the cab 7. On the frame there are wheels on which the counterweight moves along its guides. In order to unify the design of the counterweight, components and parts are used on the carriage of the cab 7. The internal volume of the counterweight frame is filled with special plates that perform the function of cargo.

Making sure that the passengers took their seats in cabin 7 and the cabin launch is safe, the operator presses the “Top” button if the cabin was located at the lower berth station 8, and accordingly “Down” if the cabin was at the top station 8. Further the control system automatically issues a command to close the doors and, by the “Closed” signal, of the control switches on the doors of the cab 7, issues a “Start” command to the engine control unit of the winch. At a signal from the control system, the brake actuator automatically decompresses the pads and smoothly turns on the winch engine. The engine smoothly accelerates the cab to a speed of 1.6-1.7 m / s. At this speed, cab 7 passes the main part of the path 5. In case of emergency situations, the conductor must stop cab 7 by pressing the “Stop” button. When approaching the mooring station 8, the speed of movement of the cabin 7 is automatically reduced to 0.15-0.1 m / s. At the exact stop sensor signal, cab 7 stops. At the signal of the switch of the closed position of the brake, the control system issues a command to open the locks of the doors of the cabin 7 and the berth station 8. The movement cycle is considered complete. From the berth station 8 in the upper part of the arch on the glazed passage 3 visitors enter the main space 2 - a hall with observation platforms.

Due to the fact that the lifting mechanisms are a special cargo-passenger vehicle, they are equipped with safety devices, fire safety system and communication system.

The ground case 9 for servicing the system is made of three floors and it contains a wardrobe, bathrooms, stairs and a large passenger elevator, which allows people with limited mobility to freely visit this object. On the second floor there are technical and engineering rooms. The third floor is occupied by the technological premises of the observation deck (restaurant) 2 and a glazed gallery leading to the elevator hall to the cabins of 7 lifting mechanisms.

Thus, the proposed design allows for a comfortable and safe delivery of passengers to the observation deck (restaurant) and admire the picturesque view from a height of 86.7 m from a transparent ellipsoid volume with a device of observation platforms designed for 100 visitors at a time.

The device lifts allows you to transport not only visitors, but also technical staff, fire departments and cargo, packed in special lifts. In case of unforeseen circumstances, the lift becomes an autonomous means for evacuating people. For emergency cases, escape ladders are also provided, which in normal situations are used to service the bridge structures.

The almost completely glazed volume of the observation deck (restaurant) 2 offers a panoramic view of the city from a bird's eye view. In the center of the hall there is a multifunctional platform for concerts, presentations, lectures, etc., equipped with the latest equipment, bars and

- 2 010768 bathrooms working offline. The lower level under the hall is a technical floor, saturated with technological rooms.

The arising vibrations in the bridge structures transmitted to the structures of the ellipsoidal volume are supposed to be damped with the help of dampers installed at the level of the technical floor, and the floating floor structure of the main hall is also used.

For fire safety purposes, a reservoir with a reserve of water is installed on the technical floor to ensure the sprinkler fire extinguishing systems. The design of the lifting mechanisms incorporated the possibility of independent safe descent from any elevation to ground level.
