Description

Technical Field

[0001] This invention relates to the field of elevator design, specifically to a novel cylindrical steel structure spiral walkway bridge with elevator. Background Technology

[0002] The cylindrical building is a circular, vertically arranged structure with vertical space inside for shaft installation. It has an exit on the cylindrical building, and a connecting corridor at the exit. Elevators are vertically arranged inside the cylindrical building. Pedestrians can reach the connecting corridor via a walkway bridge or an elevator. Its overall structure is a vertical transportation system.

[0003] For example, the Chinese patent document with authorization announcement number CN217870926U, announcement date 2022-11-22, and titled "An Outdoor Corrosion-Resistant Elevator Corridor," includes a square tube frame, a floor, and railings. The square tube frame includes two parallel main square tubes with a rust-resistant layer on their surfaces. The floor is placed on the two transverse main square tubes. The lower ends of two sets of railings are connected to the two main square tubes respectively. The floor includes multiple strip-shaped buckles with a rust-resistant layer on their surfaces. The radial cross-section of the transverse strip-shaped buckles is "U"-shaped with the opening side facing downwards. The two sides of the strip-shaped buckles are provided with snap-fit ​​structures. The multiple strip-shaped buckles are arranged side by side and interlocked by the snap-fit ​​structures. The two ends of the multiple strip-shaped buckles are respectively placed on the two main square tubes. This utility model gives the floor of the outdoor elevator corridor better rust resistance, extends the service life of the outdoor elevator corridor floor, and allows rainwater on the floor to drain away in time from the edges and also to seep through the gaps between the strip-shaped buckles, preventing water accumulation and avoiding safety hazards caused by slippery water.

[0004] The shortcomings of the aforementioned existing technology are that there is only one connecting corridor, and correspondingly, there is only one elevator opening. When there are multiple connecting corridors and the directions of the multiple connecting corridors are different, the elevator opening can only be arranged to correspond to one of the connecting corridors. Therefore, after exiting the elevator, if you need to go to the other two connecting corridors, you must go around for a distance. Summary of the Invention

[0005] The purpose of this invention is to provide a novel cylindrical steel structure spiral walkway bridge with elevator to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0015] Furthermore, a first elastic element is provided between the lifting plate and the guide rail.

[0016] The above-mentioned novel cylindrical steel structure spiral walkway bridge with elevator has two abutment surfaces, which are symmetrically arranged about the transmission block.

[0017] The above-mentioned novel cylindrical steel structure spiral walkway bridge with elevator has a limit block on the transmission block and a limit groove inside the extension, wherein the limit block and the limit groove are slidably connected.

[0037] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] In the description of this invention, it should be understood that... Figure 9 The position of the sliding seat 21 relative to the elevator 2 is upper, and vice versa. The terms "center", "length", "width", "degree", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0039] Reference Figure 1-13This invention provides a novel cylindrical steel structure spiral walkway bridge with elevator, comprising a cylindrical building 1, an elevator 2 installed inside the cylindrical building 1, and a spiral walkway bridge 3 installed outside the cylindrical building 1. At least three floors of the spiral walkway bridge 3 are connected by at least three connecting corridors 4 in different directions. The elevator 2 is provided with at least three openable elevator doors, and the multiple elevator doors correspond one-to-one with the directions of the multiple connecting corridors 4.

[0040] Specifically, the cylindrical building 1 is a circular, vertically arranged structure with an internal vertical space for shaft installation. An exit is located on the cylindrical building 1, and a connecting corridor 4 is situated at the exit. An elevator 2 is vertically arranged inside the cylindrical building 1, allowing pedestrians to reach the connecting corridor 4 via either the elevator or the ladder. The overall structure constitutes a vertical transportation system, which is existing technology and will not be elaborated upon. One of the core innovations of this embodiment is the inclusion of a spiral pedestrian bridge 3 around the outer perimeter of the cylindrical building 1. The cylindrical structure is 33.111m high. The spiral walkway bridge 3 has a central radius of 8.3m and 5.22 spiral turns. At least three floors of the spiral walkway bridge 3 are connected by three connecting corridors 4 in different directions. Inside the cylindrical building 1, an elevator 2 is vertically installed, and the elevator 2 is equipped with at least three openable doors. The multiple doors correspond one-to-one with the directions of the multiple connecting corridors 4. The purpose of this arrangement is that when the elevator 2 reaches the position of a connecting corridor 4 on a certain side, the elevator 2 and the door corresponding to that position of the connecting corridor 4 are opened, so that one can directly reach the connecting corridor 4 through the door, thereby reducing the travel distance.

[0041] Furthermore, a canopy 5 is provided at the top of the cylindrical structure 1. Specifically, the canopy 5 is conical, and the radial dimension of the canopy 5 is larger than the radial dimension of the virtual circle formed by the spiral walkway bridge 3. In rainy or snowy weather, rain and snow will slide off the surface of the canopy 5 to achieve the purpose of rain and snow protection. The cantilevered ends of the canopy 5 adopt a "double eyelid" design (e.g., double eyelid). Figure 5 As shown, the double eyelid design is an innovative construction design method that combines the structural features of the spiral walkway with the design concept of the double eyelid roof to create a unique visual effect and functionality. The double-layer design increases the sense of space and visual depth, and the overall aesthetics are further enhanced. In other words, the edge of the cantilever end of the canopy 5 has a two-layer structure.

[0042] Furthermore, a crossbeam 6 is provided between the cylindrical structure 1 and the spiral walkway bridge 3. Specifically, as shown... Figure 6 As shown, the crossbeam 6 is approximately a hollow right-angled triangle structure with a horizontal length of 2.5m. It is a one-piece steel structure used to connect the cylindrical building 1 with the spiral walkway bridge 3.

[0043] As another optional embodiment, there are two elevators 2. Specifically, both elevators 2 are three-door elevators 2, and one side of the two elevators 2 are arranged opposite each other. In this case, there are four exits in the cylindrical building 1. That is, the elevator doors of the two elevators 2 that are facing away from each other correspond to two exits respectively, and the other four elevator doors are arranged in a two-to-one arrangement with the other two exits (that is, the elevator door on one side of the two elevators 2 corresponds to one exit at the same time, and the elevator door on the other side corresponds to the other exit at the same time).

[0044] Furthermore, the elevator 2 is equipped with a forced locking mechanism. When one opening of the elevator 2 is opened, the forced locking mechanism blocks the openings on the other sides of the elevator 2. Specifically, the forced locking mechanism can be a cooperative structure of an electric push rod and a blocking member (that is, the electric push rod can drive the blocking member to move back and forth, so that the blocking member can have a position that blocks the opening and a position that is away from the opening). The purpose of this arrangement is that when the elevator 2 runs to one of the exit positions of the cylindrical building 1, the forced locking mechanism at that exit position is unlocked, so that the opening of the elevator 2 corresponding to that exit can be opened, and the other openings of the elevator 2 are blocked by their corresponding forced locking mechanisms. This can prevent the accidental situation of people falling from the other openings when the elevator 2 stops, thus improving the safety of the elevator 2.

[0045] Furthermore, the elevator 2 is provided with a first guide rail 7, on which a door panel 8 is slidably mounted. Specifically, regarding the opening on one side of the elevator 2, the first guide rail 7 is arranged along the width direction of the opening, and two staggered sliding grooves 9 are provided on the first guide rail 7. Correspondingly, two door panels 8 are also provided, with each door panel 8 slidably connected to one of the two sliding grooves 9. The door panels 8 can be reciprocated by a driving component such as a cylinder. The purpose of this arrangement is that when the opening needs to be opened, the two door panels 8 move in the same direction to one side of the opening to open it. After the opening is opened, the two door panels 8 overlap to reduce the horizontal space occupied by the elevator 2. When the opening needs to be blocked, one door panel 8 stops when it reaches halfway through the opening, while the other door panel 8 continues to move to block the other half of the opening.

[0046] Preferably, the forced locking mechanism includes a lifting plate 10 and a blocking rod 11 fixed to the lifting plate 10. The blocking rod 11 extends through the top of the first guide rail 7. When the blocking rod 11 abuts against the door panel 8, the door panel 8 is locked. It also includes a power component for driving the lifting plate 10 to move vertically. Specifically, regarding the opening on one side of elevator 2, the lifting plate 10 has a rectangular structure, and there are two blocking rods 11. Both blocking rods 11 are fixed to the upper surface of the lifting plate 10, and the two blocking rods 11 are respectively inserted into the two sliding grooves 9 of the first guide rail 7. That is, the bottom wall of the sliding groove 9 has a sliding hole, and the blocking rod 11 slides vertically in the sliding hole. The power component can be an existing reciprocating drive component such as a ball screw. The purpose of this arrangement is that when the opening of elevator 2 is opened or blocked, the blocking rod 11 retracts into the sliding hole to avoid obstruction. When the door panel 8 blocks the opening, the power component controls the blocking rod 11 to extend out of the sliding hole and abut against the side wall of the door panel 8 so that the door panel 8 cannot be opened. When the opening of elevator 2 corresponds to the exit position of the cylindrical building 1, the power component controls the blocking rod 11 to retract into the sliding hole again so that the opening on that side can be opened. This achieves active locking and unlocking of the opening.

[0047] In another embodiment of the present invention, the power assembly includes an unlocking block 12 fixed to the inner wall of the cylindrical building 1, a wedge-shaped portion 13 provided on the lifting plate 10, an extension portion 14 provided on the first guide rail 7, a transmission block 15 slidably provided on the extension portion 14, one end of the transmission block 15 abutting against the wedge portion 13, and an abutting surface 16 provided on the other end of the transmission block 15, the unlocking block 12 being located on the movement stroke of the abutting surface 16; and a first elastic member 17 is provided between the lifting plate 10 and the first guide rail 7. Specifically, the unlocking block 12 preferably has a square cross-section, and the side near the elevator 2 is chamfered. There are multiple unlocking blocks 12, each corresponding to an exit of a multiple cylindrical building 1. The extension 14 is a plate-like structure protruding downwards from the edge of the first guide rail 7, with a horizontal groove 18 inside. The transmission block 15 can move horizontally under the limiting action of the horizontal groove 18. The lifting plate 10 is slidably connected to the extension 14, and a transmission groove is provided inside the lifting plate 10. The bottom wall of the transmission groove is inclined. The wedge-shaped portion 13 is the inclined structure of the bottom wall of the transmission groove. The end of the transmission block 15 near the wedge-shaped portion 13 is also chamfered. The contact surface 16 is an inclined surface set on the transmission block 15. There are three transmission blocks 15, which are arranged corresponding to the three openings of the elevator 2. The first elastic element 17 is preferably a spring, one end of which is fixed to the lower surface of the first guide rail 7, and the other end is fixed to the upper surface of the lifting plate 10. The purpose of this arrangement is that during the operation of the elevator 2, all three openings are blocked. When the elevator 2 is in operation... When the elevator 2 moves vertically within the cylindrical building 1, and when it reaches one of the exit positions of the cylindrical building 1, the transmission block 15 on the side corresponding to that exit will abut against the unlocking block 12, causing the transmission block 15 to abut against the wedge-shaped part 13. This will drive the lifting plate 10 and the blocking rod 11 to move downwards, so that the end of the blocking rod 11 retracts into the sliding hole, thereby achieving passive unlocking of the door panel 8 on that side. (Since the transmission blocks 15 on the other two sides are not abutting against the unlocking block 12 at this time, the door panels 8 on these two sides will always keep the door closed.) The door panel 8 abuts against the door, preventing it from opening and thus achieving a forced locking effect. It also stores force in the first elastic element 17. After the personnel have passed through, the opening closes, and the elevator 2 continues to run. When the transmission block 15 moves away from the unlocking block 12, the elastic force of the first elastic element 17 is released, causing the blocking rod 11 to re-insert into the slide groove 9, thereby achieving a passive locking of the door panel 8. During this process, the transmission block 15 will move in the opposite direction due to the abutment between the wedge-shaped part 13 and the transmission block 15, thereby achieving automatic reset.

[0048] Preferably, there are two abutment surfaces 16, which are symmetrically arranged about the transmission block 15. The two abutment surfaces 16 are respectively located on the upper and lower sides of the transmission block 15. When the elevator 2 moves upward, the upper abutment surface 16 of the transmission block 15 abuts against the unlocking block 12. When the elevator 2 moves downward, the lower abutment surface 16 of the transmission block 15 abuts against the unlocking block 12. In this way, the elevator 2 can be passively unlocked and locked whether it is moving upward or downward.

[0049] Furthermore, a limiting block 19 is provided on the transmission block 15, and a limiting groove 20 is formed inside the extension 14. The limiting block 19 is slidably connected to the limiting groove 20. Specifically, the limiting block 19 is located on the upper surface of the transmission block 15, near the middle of the transmission block 15. The limiting groove 20 is formed on the inner top wall of the horizontal groove 18, and the length of the limiting groove 20 is greater than the width of the limiting block 19. This allows the limiting block 19 to slide inside the limiting groove 20. When the transmission block 15 moves to the end of its two strokes, the limiting block 19 will abut against the inner walls of the two sides of the limiting groove 20, thereby preventing the transmission block 15 from disengaging from the extension 14. When the elevator 2 is running, under the elastic force of the first elastic member 17, the limiting block 19 abuts against the end of the limiting groove 20 near the unlocking block 12 to prevent the transmission block 15 from shaking arbitrarily. At this time, the end of the unlocking block 12 is located on the movement stroke of the abutment surface 16.

[0050] It should be noted that in the event of an emergency such as an earthquake, if elevator 2 is in operation (especially during its upward movement, where continued upward movement would place people in a more dangerous situation), the locking effect of the forced locking mechanism will lock multiple openings of elevator 2, trapping people inside and causing them to miss the best escape opportunity. To solve this problem, as another embodiment of the present invention, elevator 2 is equipped with an emergency unlocking mechanism for unlocking the forced locking mechanism. Specifically, the emergency unlocking mechanism can be multiple electric push rods, each connected to multiple lifting plates 10. In an emergency, the electric push rods drive the multiple lifting plates 10 to move downwards synchronously, opening all three openings of elevator 2 simultaneously to facilitate escape.

[0051] As an alternative to the aforementioned electric push rod driving the lifting plate 10 to move vertically, the emergency unlocking mechanism includes a sliding seat 21 fixed to the top of the elevator 2 and a transmission rope 22. A transmission plate 23 is slidably disposed inside the sliding seat 21. The transmission plate 23 is fixedly connected to the transmission rope 22, and a second elastic element 24 is disposed between the transmission plate 23 and the elevator 2. A transmission rod 25 is fixedly connected to the transmission plate 23, and the lifting plate 10 is located on the travel stroke of the transmission rod 25. Specifically, the transmission rope 22 is preferably a steel wire rope, fixedly connected to the top of the elevator 2, and connected to the lifting mechanism at the top of the cylindrical building 1. During normal operation of the elevator 2, the transmission rope 22 remains taut under its own gravity. The sliding seat 21 has a hollow shell structure, and the size of the transmission plate 23 is adapted to the internal space of the sliding seat 21 so that the transmission plate 23 can slide vertically inside the sliding seat 21. A through hole is provided at the top of the sliding seat 21 for the transmission rope 22 to pass through. The transmission plate 23 and the transmission rope 22 are fixedly connected... Next, the second elastic element 24 is also preferably a spring, with one end fixed to the lower surface of the transmission plate 23 and the other end fixed to the upper surface of the elevator 2. The elastic force of the second elastic element 24 is greater than the sum of the elastic forces of the multiple first elastic elements 17. That is, when the second elastic element 24 contracts, it will cause the multiple first elastic elements 17 to extend simultaneously. The transmission rod 25 is approximately C-shaped. Each of the multiple lifting plates 10 is provided with a connecting part 26, and the ends of the multiple connecting parts 26 extend to the bottom of the elevator 2. The side wall of the sliding seat 21 is provided with a through groove 27, and one end of the transmission rod 25 The second elastic element 24 is fixed to the transmission plate 23 through the through slot 27, and the other end is located above the multiple connecting parts 26. The purpose of this arrangement is that, during normal operation of the elevator 2, the second elastic element 24 is always in a stretched state under the tension of the transmission rope 22, and the transmission plate 23 is close to the top of the sliding seat 21. When an earthquake occurs, the elevator 2 will be in a state of weightlessness for a short time. At this time, the transmission rope 22 is not under stress, and at the same time, the elastic force of the second elastic element 24 is released, thereby causing the transmission plate 23 to slide towards the bottom of the sliding seat 21, and synchronously with the belt. The transmission rod 25 moves downward, causing it to abut against the connecting part 26. This causes multiple lifting plates 10 and blocking rods 11 to move downward simultaneously, unlocking all three openings of the elevator 2 and storing force on the first elastic element 17. When the elevator 2 returns to normal, the transmission rope 22 straightens again, pulling the transmission plate 23 and transmission rod 25 upward and storing force on the second elastic element 24. At this time, the transmission rod 25 moves away from the connecting part 26, and the elastic force of the first elastic element 17 is released, causing the lifting plates 10 and blocking rods 11 to automatically reset.

[0052] It should be noted that an emergency button (not shown) can be installed inside elevator 2. The emergency button can be electrically connected to a cylinder. When the emergency button is pressed, multiple openings of elevator 2 can be opened by the cylinder. However, when elevator 2 is running normally, the forced locking mechanism locks the elevator door, and the elevator door cannot be opened even if the emergency button is pressed.

[0053] Preferably, the elevator 2 has a vertical groove 28, and the transmission rod 25 is slidably connected to the vertical groove 28. Specifically, the vertical groove 28 is located on the back of the elevator 2, and the vertical section of the transmission rod 25 is slidably connected to the vertical groove 28 to improve the stability of the transmission rod 25 during lifting and lowering.

[0054] In another embodiment of the present invention, the elevator 2 is provided with an anti-reverse assembly to prevent the blocking rod 11 from rebounding twice. The anti-reverse assembly includes a first anti-reverse block 29 disposed on the transmission rod 25, and a second anti-reverse block 30 fixedly connected to the elevator 2, wherein the first anti-reverse block 29 abuts against the second anti-reverse block 30. Specifically, two first check blocks 29 and two second check blocks 30 are provided, and they are symmetrically arranged about the transmission rod 25. The first check block 29 is located on the side of the transmission rod 25 and is staggered from the vertical groove 28. The first check block 29 has a wedge-shaped surface. The second check block 30 is located on the back of the elevator 2 and is preferably an elastic telescopic block (i.e., it has a spring inside, which will cause it to contract or extend when subjected to axial force). The purpose of this arrangement is that when the elevator 2 is running normally, the elastic telescopic block is in a compressed state, and the second check block 30, under its own elastic force, causes the side of the first check block 29 to abut. When the emergency unlocking mechanism is triggered to move the transmission rod 25 downward, it will drive the first check block 29 to move downward synchronously. When the return block 29 and the second check block 30 are misaligned, the elastic force inside the second check block 30 is released, causing the second check block 30 to extend. At this time, the end of the second check block 30 is located above the first check block 29, thereby limiting the upward stroke of the first check block 29. This prevents the transmission rod 25 from moving upward after it comes into contact with the connecting part 26, thus ensuring that multiple forced locking mechanisms are in a stable unlocked state. At this time, multiple openings of the elevator 2 can be opened, thereby improving the safety of the elevator 2. Furthermore, during the downward movement of the first check block 29, the edge of the extended second check block 30 will come into contact with the wedge-shaped surface of the first check block 29, thereby providing a downward force to the first check block 29 to provide assistance during the downward movement of the transmission rod 25.

[0055] Furthermore, it also includes a second guide rail 31, to which the elevator 2 is slidably connected. The second guide rail 31 has a slot 32, and a locking rod 33 is fixedly connected to the second check block 30. Specifically, the second guide rail 31 has a protruding portion, and multiple slots 32 are equidistantly arranged on the protruding portion of the second guide rail 31. The locking rod 33 is fixedly connected to a horizontally movable part of the second check block 30. This arrangement ensures that during normal operation of the elevator 2, the second check block 30 is in a compressed state, thus the locking rod 33 is far from the slot 32. When the first check block 29 and the second check block 30 are misaligned, the second check block 30 extends, causing the locking rod 33 to move towards the slot 32. When one of the slots 32 overlaps, the locking rod 33 engages with the slot 32, preventing the elevator 2 from continuing to move vertically and thus achieving an emergency braking effect. After the emergency is over, a force is applied to the locking rod 33 in a direction away from the slot 32 (a reciprocating drive structure such as an electric push rod can be installed on the back of the elevator 2, not shown), so that the locking rod 33 unlocks from the slot 32. At the same time, the locking rod 33 will drive the second check block 30 to move away synchronously. At this time, under the action of the elevator 2's gravity, the transmission rope 22 straightens and stretches the transmission plate 23, thereby driving the transmission plate 23 to reset and driving the transmission rod 25 to move upward relative to the elevator 2. At this time, the side of the first check block 29 and the side of the second check block 30 abut again to achieve the automatic reset of the transmission rod 25.

[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
