Description

Technical Field

[0001] The present invention relates to the field of elevator design, and particularly to a new type of steel structure spiral walkway bridge with an elevator for a cylindrical body. Background Art

[0002] The cylindrical building has a circular vertical layout structure, with a vertical space inside for installing a hoistway. There are exits on the cylindrical building, and a connecting corridor is arranged at the exit position. An elevator is vertically arranged inside the cylindrical building. Pedestrians can reach the connecting corridor through the walkway bridge or through the elevator, and its overall structure is a vertical traffic system.

[0003] For example, in a Chinese patent document with the authorization公告号为CN217870926U, the公告日期为2022-11-22, and the name为《一种户外防腐蚀电梯连廊》, it includes a square tube frame, a floor, and railings. The square tube frame includes two main square tubes that are parallel to each other and have an anti-rust layer on the surface. The floor is placed on the two transverse main square tubes. The lower ends of the two groups of railings are respectively connected to the two main square tubes. The floor includes multiple strip-shaped buckles with an anti-rust layer on the surface. The radial cross-section of the transverse strip-shaped buckle is "匚"-shaped and the opening side is downward. Clamping structures are respectively arranged on both side edges of the strip-shaped buckle. Multiple strip-shaped buckles are arranged side by side and are clamped to each other through the clamping structures. The two ends of multiple strip-shaped buckles are respectively placed on the two main square tubes. This utility model enables the floor of the outdoor elevator connecting corridor to have better anti-rust function, extends the service life of the floor of the outdoor elevator connecting corridor, the rainwater on the floor can be discharged in time from the edge, and can also seep through the gaps between the strip-shaped buckles in time, and no water accumulation will be formed, avoiding potential safety hazards caused by water accumulation and slipperiness.

[0037] In order 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 the present invention, it is necessary to understand that Fig. 9 The position of the middle sliding seat 21 relative to the elevator 2 is up, and vice versa. The terms "center", "length", "width", "degree", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] Reference Figure 1-13A novel cylindrical steel-structured spiral walkway bridge with an elevator provided in an embodiment of the present invention comprises a cylindrical building 1, an elevator 2 is arranged inside the cylindrical building 1, a spiral walkway bridge body 3 is arranged outside the cylindrical building 1, at least three floors of the spiral walkway bridge body 3 are connected with at least three corridors 4 in different directions, the elevator 2 is provided with at least three openable elevator doors, and the multiple elevator doors correspond to the directions of the multiple corridors 4 one by one.

[0040] Specifically, the cylindrical building 1 is a circular vertically arranged structure, and a vertical space for the installation of a well is arranged inside it. An exit is arranged on the cylindrical building 1, and a corridor 4 is arranged at the exit position. An elevator 2 is arranged vertically inside the cylindrical building 1. Pedestrians can reach the corridor 4 by climbing a ladder or by taking the elevator 2. The overall structure is a vertical transportation system. This is a prior art and will not be repeated. One of the core innovations of the embodiment of the present invention is that a spiral walkway bridge 3 is arranged on the periphery of the cylindrical building 1. The cylindrical structure is 33.111 meters high. The central radius of the spiral walkway bridge body 3 is 8.3m, the number of spiral turns is 5.22, and at least three floors of the spiral walkway bridge body 3 are connected with corridors 4 in three different directions. An elevator 2 is vertically arranged inside the cylindrical building 1, and at least three openable stair doors are arranged on the elevator 2, and the multiple stair doors correspond to the directions of the multiple corridors 4 one by one. The purpose of such arrangement is that when the elevator 2 reaches the corridor 4 position on one side, the stair doors corresponding to the position of the corridor 4 are opened, so that the elevator 2 can directly reach the corridor 4 through the stair doors to reduce the travel distance.

[0041] Furthermore, a canopy 5 is provided at the top of the cylindrical building 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 body 3. When encountering rainy and snowy weather, rain and snow will slide down through the surface of the canopy 5 to achieve the purpose of preventing rain and snow, and the cantilever end of the canopy 5 adopts "double eyelids" (such as Figure 5 As shown, the double-eyelid design is an innovative construction design technique. It combines the structural characteristics of the spiral walkway with the design concept of the double-eyelid roof to create a unique visual effect and usage function. The double-layer design increases the sense of hierarchy and visual depth of the space, and the overall aesthetics is further reflected) approach, that is, the edge position of the cantilever end of the awning 5 is a two-layer structure.

[0042] Furthermore, a crossbeam 6 is provided between the cylindrical building 1 and the spiral walkway bridge body 3. Specifically, Figure 6 As shown, the cross beam 6 as a whole is approximately a right-angled triangle structure with a hollow interior, and the horizontal length of the cross beam 6 is 2.5 m. It is an integrally formed steel structure and is used to connect the cylindrical building 1 with the spiral walkway bridge body 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 is arranged correspondingly. In this case, there are four corresponding exits of the cylindrical building 1, that is, the elevator doors of the two elevators 2 that are separated from each other correspond to two exits respectively, and the remaining four elevator doors are arranged two to one 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 provided with a forced locking mechanism, and when one of the openings on one side 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 matching 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 to block the opening and a position away from the opening). The effect of such a setting is that when the elevator 2 runs to one of the exit positions of the cylindrical building 1, the forced locking mechanism at the exit position is unlocked, so that the opening of the elevator 2 corresponding to the exit can be opened, and the remaining openings of the elevator 2 are blocked by the corresponding forced locking mechanisms, so that the accident of people falling from the remaining openings when the elevator 2 is parked can be avoided, thereby 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 provided. Specifically, with respect to 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 slide grooves 9 are provided on the first guide rail 7, and correspondingly, two door panels 8 are also provided, and the two door panels 8 are respectively slidably connected to the two slide grooves 9, and the door panels 8 can be reciprocated by a driving member such as a cylinder, and the effect of such a setting 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 the opening, and after the opening is opened, the two door panels 8 overlap to reduce the horizontal space occupied by the elevator 2, and when the opening needs to be blocked, one of the door panels 8 stops when it runs to the position of half of the opening, and 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, wherein the blocking rod 11 extends to the top of the first guide rail 7, and when the blocking rod 11 abuts against the door panel 8, the door panel 8 is locked; and also includes a power component for driving the lifting plate 10 to move vertically. Specifically, with regard to the opening on one side of the elevator 2, the lifting plate 10 is a rectangular structure, and there are two blocking rods 11. The two 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 slide grooves 9 of the first guide rail 7, that is, the bottom wall of the slide groove 9 is provided with 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 such a setting is that when the opening of the elevator 2 is opened or blocked, the blocking rod 11 retracts to the inside of the sliding hole to achieve avoidance. When the door panel 8 blocks the opening, the power component controls the blocking rod 11 to extend out of the sliding hole, and at this time it abuts against the side wall of the door panel 8, so that the door panel 8 cannot be opened. When the opening of the 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 this side is in a state that can be opened, thereby achieving active locking and unlocking of the opening.

[0047] As another embodiment of the present invention, the power assembly includes an unlocking block 12 fixedly connected to the inner wall of the cylindrical building 1, a wedge-shaped portion 13 is provided on the lifting plate 10, an extension portion 14 is provided on the first guide rail 7, a transmission block 15 is slidably provided on the extension portion 14, one end of the transmission block 15 abuts against the wedge-shaped portion 13, and an abutting surface 16 is provided on the other end of the unlocking block 12, and the unlocking block 12 is 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 cross section of the unlocking block 12 is preferably a square structure, and the side close to the elevator 2 is chamfered, and there are multiple unlocking blocks 12, and the multiple unlocking blocks 12 are respectively arranged corresponding to the exits of the multiple cylindrical buildings 1, and the extension 14 is a plate-shaped structure protruding downward from the edge of the first guide rail 7, and a horizontal groove 18 is opened inside it. The transmission block 15 can move horizontally under the limiting action of the horizontal groove 18, and the lifting plate 10 is slidably connected to the extension 14, and a transmission groove is opened inside the lifting plate 10, and the bottom wall of the transmission groove is inclined. The wedge-shaped portion 13 is an inclined structure of the bottom wall of the transmission groove. The end of the transmission block 15 close to the wedge-shaped portion 13 is also chamfered. The abutment surface 16 is an inclined surface arranged on the transmission block 15. The transmission block 15 is provided with three, which are arranged corresponding to the three openings of the elevator 2 respectively. The first elastic member 17 is preferably a spring, one end of which is fixedly connected to the lower surface of the first guide rail 7, and the other end is fixedly connected to the upper surface of the lifting plate 10. The effect of such a setting is that during the operation of the elevator 2, the three openings are all in a blocked state. When the elevator 2 is in When the elevator 2 moves vertically in the cylindrical building 1, and when the elevator 2 runs to one of the exit positions of the cylindrical building 1, the transmission block 15 on the side corresponding to the exit of the elevator 2 will abut against the unlocking block 12, so that the transmission block 15 will abut against the wedge-shaped portion 13, thereby driving the lifting plate 10 and the blocking rod 11 to move downward, so that the end of the blocking rod 11 is retracted into the sliding hole, so as to realize the passive unlocking of the side door panel 8 (because at this time, the transmission blocks 15 on the other two sides are not abutted against the unlocking block 12, so the door panels 8 on these two sides are always closed). The first elastic member 17 is forced to store force. When the personnel have passed through, the opening is closed. At this time, the elevator 2 continues to run. When the transmission block 15 is away from the unlocking block 12, the elastic force of the first elastic member 17 is released, so that the blocking rod 11 is inserted into the slide groove 9 again to achieve passive locking of the door panel 8. In this process, the wedge-shaped portion 13 abuts against the transmission block 15, which drives the transmission block 15 to move in the opposite direction to achieve automatic resetting.

[0048] Preferably, two abutting surfaces 16 are provided, and the two abutting surfaces 16 are symmetrically arranged about the transmission block 15. The two abutting surfaces 16 are respectively provided on the upper and lower sides of the transmission block 15, and when the elevator 2 goes up, the upper abutting surface 16 of the transmission block 15 abuts against the unlocking block 12, and when the elevator 2 goes down, the lower abutting surface 16 of the transmission block 15 abuts against the unlocking block 12, so that the elevator 2 can be passively unlocked and locked when going up or down.

[0049] Furthermore, a limit block 19 is provided on the transmission block 15, and a limit slot 20 is provided inside the lifting plate 10, and the limit block 19 is slidably connected with the limit slot 20. Specifically, the limit block 19 is provided on the upper surface of the transmission block 15, and is close to the middle of the transmission block 15, the limit slot 20 is provided on the inner top wall of the horizontal slot 18, and the length of the limit slot 20 is greater than the width of the limit block 19, so that the limit block 19 can slide inside the limit slot 20, and when the transmission block 15 moves to the two stroke ends, the limit block 19 will respectively abut against the inner walls on both sides of the limit slot 20, thereby preventing the transmission block 15 from being separated from the extension portion 14, and when the elevator 2 is running, under the elastic force of the first elastic member 17, the limit block 19 abuts against one end of the limit slot 20 close to the unlocking block 12, so as to prevent the transmission block 15 from shaking at will, and at this time, the end of the unlocking block 12 is located on the movement stroke of the abutting surface 16.

[0050] It should be noted that when an emergency such as an earthquake occurs, if the elevator 2 is in operation (especially when the elevator 2 is moving upward, if an emergency occurs, the elevator 2 will continue to move upward, which will put people in a more dangerous situation), due to the locking effect of the forced locking mechanism, the multiple openings of the elevator 2 are locked, which will trap the internal personnel in the elevator 2, thereby missing the best escape opportunity. To solve the above problem, as another embodiment of the present invention, the elevator 2 is provided with an emergency unlocking mechanism for unlocking the forced locking mechanism. Specifically, the emergency unlocking mechanism can be a plurality of electric push rods, which are respectively connected to a plurality of lifting plates 10. When an emergency situation occurs, the electric push rods drive the plurality of lifting plates 10 to move downward synchronously, so as to realize that the three openings of the elevator 2 are opened at the same time, so as to facilitate escape.

[0051] As an alternative to the above-mentioned electric push rod driving the lifting plate 10 to move vertically, the emergency unlocking mechanism includes a sliding seat 21 fixedly connected to the top of the elevator 2 and a transmission rope 22. A transmission plate 23 is slidably arranged inside the sliding seat 21. The transmission plate 23 is fixedly connected to the transmission rope 22, and a second elastic member 24 is arranged 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 movement stroke of the transmission rod 25. Specifically, the transmission rope 22 is preferably a steel wire rope. The transmission rope 22 is fixedly connected to the top of the elevator 2 and connected to the lifting mechanism at the top of the cylindrical building 1. When the elevator 2 is operating normally, the transmission rope 22 is always in a straight state under the action of its own gravity. The sliding seat 21 is a hollow shell structure. 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 opened on 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. The second elastic member 24 is also preferably a spring, one end of which is fixed to the lower surface of the transmission plate 23, and the other end is fixed to the upper surface of the elevator 2, and the elastic force of the second elastic member 24 is greater than the sum of the elastic forces of the plurality of first elastic members 17, that is, when the second elastic member 24 contracts, it will drive the plurality of first elastic members 17 to extend at the same time, the transmission rod 25 is approximately C-shaped, and the plurality of lifting plates 10 are respectively provided with connecting parts 26, and the ends of the plurality of connecting parts 26 extend to the bottom of the elevator 2, and 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 member 24 is fixedly connected to the transmission plate 23 through the through groove 27, and the other end is located above the plurality of connecting parts 26. The purpose of such a setting is that when the elevator 2 is operating normally, the second elastic member 24 is always in a stretched state under the stretching effect 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 weightless state for a short time. At this time, the transmission rope 22 is in a stress-free state. At the same time, the elastic force of the second elastic member 24 is released, so that the transmission plate 23 slides toward the bottom end of the sliding seat 21, and the synchronous belt The transmission rod 25 moves downward, so that the transmission rod 25 abuts against the connecting portion 26, which will drive multiple lifting plates 10 and the blocking rod 11 to move downward synchronously, so that the three openings of the elevator 2 are all unlocked, and the first elastic member 17 is charged. When the elevator 2 returns to normal, the transmission rope 22 is straightened again to pull the transmission plate 23 and the transmission rod 25 upward, and the second elastic member 24 is charged. At this time, the transmission rod 25 is away from the connecting portion 26, and the elastic force of the first elastic member 17 is released to drive the lifting plate 10 and the blocking rod 11 to automatically reset.

[0052] It should be noted that an emergency button (not shown) can be provided inside the elevator 2, and the emergency button can be electrically connected to the cylinder. When the emergency button is pressed, multiple openings of the elevator 2 can be opened through the cylinder. However, when the elevator 2 is operating 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 is provided with a vertical slot 28, and the transmission rod 25 is slidably connected to the vertical slot 28. Specifically, the vertical slot 28 is provided on the back of the elevator 2, and the vertical section of the transmission rod 25 is slidably connected to the vertical slot 28 to improve the stability of the transmission rod 25 when it is lifted or lowered.

[0054] As another embodiment of the present invention, the elevator 2 is provided with a back-stop assembly for preventing the blocking rod 11 from rebounding a second time. The back-stop assembly includes a first back-stop block 29 provided on the transmission rod 25, and a second back-stop block 30 is fixedly connected to the elevator 2, and the first back-stop block 29 abuts against the second back-stop block 30. Specifically, there are two first check blocks 29 and two second check blocks 30, and they are symmetrically arranged about the transmission rod 25. The first check block 29 is arranged on the side of the transmission rod 25 and is staggered with the vertical groove 28. The first check block 29 is provided with a wedge-shaped surface, and the second check block 30 is provided on the back of the elevator 2. It is preferably an elastic telescopic block (that is, it has a spring inside, which will shrink or stretch when it is subjected to axial force). The purpose of such a setting is that when the elevator 2 is operating normally, the elastic telescopic block is in a compressed state, and the second check block 30 abuts against the side of the first check block 29 under the action of its own elastic force. 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 is offset from the second check block 30, the elastic force inside the second check block 30 is released, thereby extending the second check block 30. 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, so that the transmission rod 25 cannot move upward after abutting against the connecting portion 26, thereby making the multiple forced locking mechanisms all in a stable unlocked state. At this time, the multiple openings of the elevator 2 can all be opened, thereby improving the safety of the elevator 2, and in the process of the first check block 29 moving downward, the edge position of the second check block 30 when extended will abut against the wedge surface of the first check block 29, thereby providing a downward force to the first check block 29 to provide a boost to the transmission rod 25 during the downward movement.

[0055] Furthermore, it also includes a second guide rail 31, and the elevator 2 is slidably connected to the second guide rail 31. The second guide rail 31 is provided with a slot 32, and the second check block 30 is fixedly connected with a connecting rod 33. Specifically, the second guide rail 31 has a protruding part, and the slot 32 has multiple slots 32. The multiple slots 32 are equidistantly arranged on the protruding part of the second guide rail 31, and the connecting rod 33 is fixedly connected to the position where the second check block 30 can move horizontally. The effect of such a setting is that during the normal operation of the elevator 2, since the second check block 30 is in a compressed state, the connecting rod 33 is away from the slot 32. When the first check block 29 and the second check block 30 are staggered, the second check block 30 extends to drive the connecting rod 33 to move in the direction of the slot 32. When the connecting rod 33 and When one of the slots 32 overlaps, the engaging rod 33 will engage with the slot 32, so that the elevator 2 cannot continue to move vertically, so as to achieve the effect of emergency braking. When the emergency situation is relieved, a force is provided to the engaging rod 33 in the direction away from the slot 32 (a reciprocating drive structure such as an electric push rod can be provided on the back of the elevator 2, not shown in the figure), so that the engaging rod 33 and the slot 32 are unlocked. At the same time, the engaging rod 33 will drive the second check block 30 to avoid synchronously. At this time, under the action of the gravity of the elevator 2, the transmission rope 22 is straightened, and the transmission plate 23 is stretched to drive the transmission plate 23 to reset, and drive 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 are abutted again to achieve automatic reset of the transmission rod 25.
