[0002] In recent years, with the promotion of the renovation of old residential areas and the construction of age-friendly facilities, more and more residential buildings have begun to install outdoor elevators to solve the travel problems of high-rise residents.

[0003] The foundation of an outdoor elevator is usually fixed to the foundation road surface by pouring. However, when the elevator operates, it will generate certain vibrations, which will be transmitted to the surrounding ground through the elevator foundation structure, and then have an adverse impact on the surrounding building structures, underground pipelines, etc., and cause noise. Summary of the Invention

[0004] In order to reduce the vibrations transmitted to the surrounding road surface when the elevator operates, this application provides a foundation fixing structure for an outdoor elevator.

[0005] This application provides a foundation fixing structure for an outdoor elevator, adopting the following technical solutions: A foundation fixing structure for an outdoor elevator, comprising: A foundation base, in which an installation pit is excavated; A first casting body, located in the installation pit and fixed to the foundation base; A second casting body, located in the installation pit and directly above the first casting body; A vibration isolation support, connected between the first casting body and the second casting body for supporting the second casting body; and A steel bracket, fixedly connected to the second casting body and extending upward out of the installation pit.

[0006] By adopting the above technical solutions, by setting the foundation base, the first casting body, the second casting body and the vibration isolation support, a double-layer casting structure is formed. The vibration isolation support can effectively absorb and buffer the vibrations generated when the elevator operates, reduce the transmission of vibrations to the surrounding foundation base, and thus reduce noise and the impact on the surrounding structures.

[0007] Optionally, the first casting body includes a first component and an installation group; the first component is cast into shape, the installation group corresponds to the vibration isolation support one by one, and each installation group includes a plurality of sleeves embedded in the first component, and the vibration isolation support is connected to the sleeve through a first threaded member.

[0008] By adopting the above technical solutions, the embedded sleeves enhance the overall strength of the first casting body, so that the vibration isolation support is not easily loosened or displaced during long-term use.

[0009] Optionally, each installation group further includes a connecting pipe, an inlet pipe and an outlet pipe; the connecting pipe is used to connect the sleeves in the same installation group; the inlet pipe connects one of the sleeves and the upper surface of the first component; the outlet pipe connects another sleeve and the upper surface of the first component.

[0010] By adopting the above technical solution and arranging the connecting pipe, the inlet pipe and the outlet pipe, the slurry can evenly fill the sleeve and its connecting parts, thereby enhancing the bonding force between the sleeve and the first component.

[0011] Optionally, the second casting body includes a second component, a base plate and a enclosure; the base plate abuts against the vibration isolation seat and is connected through a second screw member; the enclosure encloses the periphery of the base plate to jointly form a casting cavity for casting the second component.

[0012] By adopting the above technical solution, the second screw member is fixed in the second component after the casting cavity is cast, so as to improve the stability between the bottom plate and the vibration isolation seat.

[0013] Optionally, the second threaded member is simultaneously connected to the steel bracket, and the bottom of the steel bracket is simultaneously embedded in the second component.

[0014] By adopting the above technical solution, the second threaded member connects the steel bracket and the second cast body at the same time, so that the steel bracket and the second cast body form an integrated structure, which enhances the overall stability and reduces the risk of loosening due to vibration.

[0015] Optionally, the second threaded member includes a locking bolt and a locking head; the steel bracket has a base for the locking bolt to pass through, and the locking bolt rod passes through the base plate and the base in sequence from bottom to top; the locking head is threadedly sleeved on the locking bolt rod, so that the locking head and the locking bolt head jointly clamp the base plate and the base; Wherein, the diameter of the through hole on the base for the locking bolt rod to pass through is larger than the outer diameter of the locking bolt rod.

[0016] By adopting the above technical solution, the cooperation between the through hole and the locking bolt allows the steel bracket to be fine-tuned during installation, thereby improving the installation accuracy.

[0017] Optionally, the steel support is connected to a shielding member extending to be opposite to the upper surface of the foundation, and the shielding member is distributed along the circumference of the installation pit.

[0018] By adopting the above technical solution, the provision of the shielding member can prevent debris from falling into the installation pit.

[0019] Optionally, the shielding member includes an enclosing frame and a hinge plate; the enclosing frame is sleeved on the steel support along the circumferential direction of the foundation pit, the hinge plate is hinged to the outside of the enclosing frame, and the hinge plate is opposite to the upper surface of the foundation and the inner cavity of the installation pit at the same time; The enclosing frame and the hinge plate are provided with an adjusting assembly, and the adjusting assembly switches the hinge plate between a first state and a second state; the first state is characterized in that there is a movable gap between the hinge plate and the upper surface of the foundation; the second state is characterized in that the hinge plate rotates to abut against the upper surface of the foundation, closing the movable gap.

[0020] By adopting the above technical solution, when the external environment is flooded, the hinge plate can be adjusted to the second state through the adjusting assembly to close the movable gap, so that the accumulated water is not easy to enter the installation pit from the movable gap.

[0021] Optionally, the adjusting assembly includes A moving frame, sleeved on the steel support, capable of moving relative to the steel support vertically; A telescopic power source, with the base end installed on the enclosing frame and the telescopic end connected to the moving frame, for driving the moving frame to move; A guide rod, with one end hinged to the hinge plate, and the hinge axis parallel to the rotation axis of the hinge plate relative to the enclosing frame; the other end passes through the moving frame downward; and A counterweight, connected to the end of the guide rod away from the hinge plate; Wherein, when the telescopic end of the telescopic power source retracts, the moving frame supports the hinge plate to keep the hinge plate in the first state; when the telescopic end of the telescopic power source extends, it drives the moving frame to push the counterweight downward, so that the hinge plate moves to the second state.

[0022] By adopting the above technical solution, the adjusting assembly realizes the automatic state switching of the hinge plate through the cooperation of the telescopic power source and the counterweight, with simple operation and rapid response.

Detailed Embodiments

[0028] The following will Figures 1-5 further describe the present application in detail with reference to the attached

[0029] The embodiment of the present application discloses a foundation fixing structure for an outdoor elevator. Refer to Figure 1 and Figure 2, the foundation fixing structure of the outdoor elevator includes a foundation 1, a first casting 3, a second casting 4, a vibration isolation support 5, and a steel bracket 6. An installation pit 2 is excavated on the foundation 1, and the bottom of the steel bracket 6, the second casting 4, the vibration isolation support 5, and the first casting 3 are sequentially distributed in the installation pit 2 from top to bottom.

[0030] Referring to Figure 3 and Figure 4 , wherein, the installation pit 2 is in the shape of a square pit. For the first casting 3, the first casting 3 includes a first member 31 and an installation group 32. The first member 31 is formed by pouring concrete in the installation pit 2, and the first member 31 is fixed to the bottom surface and the surrounding of the installation pit 2 by pouring. The installation group 32 is embedded in the first member 31 for installing the vibration isolation support 5, and the installation group 32 corresponds to the vibration isolation support 5 one by one. The installation group 32 is made of steel, and when the first member 31 is poured, a steel cage can be placed in the pouring cavity of the first member 31 so that the first casting 3 forms a reinforced concrete structure.

[0031] Each installation group 32 includes a sleeve 321, a connecting pipe 322, a feeding pipe 323, and a discharging pipe 324. The sleeve 321 is in the shape of a cylinder with a hollow interior, an open top, and an axis extending vertically. The top surface of the sleeve 321 is flush with the upper surface of the first member 31, and a plurality of sleeves 321 in each installation group 32 are arranged in an array. The connecting pipe 322 is connected between adjacent two sleeves 321, and the connecting pipe 322 extends horizontally and is located in the middle of the sleeve 321. The feeding pipe 323 is in the shape of an L with a hollow interior and both ends connected. One end is connected to one of the sleeves 321, and the other end is flush with the upper surface of the first member 31, and the end of the feeding pipe 323 connected to the sleeve 321 is close to the bottom of the sleeve 321. The discharging pipe 324 is in the shape of an L with a hollow interior and both ends connected. One end is connected to one of the sleeves 321, and the other end is flush with the upper surface of the first member 31, and the end of the discharging pipe 324 close to the sleeve 321 is located in the middle of the sleeve 321. It should be noted that the sleeves 321 to which the feeding pipe 323 and the discharging pipe 324 are connected are different.

[0032] The lower end of the vibration isolation support 5 has a first mounting plate 18, and the upper end has a second mounting plate 19. The first mounting plate 18 has first mounting holes corresponding to the sleeves 321 in the corresponding installation group 32 one by one. The vibration isolation support 5 is installed on the installation group 32 through a first threaded member 7. In this embodiment, the vibration isolation support 5 is arranged at the four corners of the first member 31. In other embodiments, the vibration isolation support 5 can also be added in the middle of the first member 31. Specifically, the first threaded member 7 is a bolt. The rod portion of the first threaded member 7 passes through the first mounting hole and is threadedly connected to the sleeve 321, so that the head of the first threaded member 7 presses the first mounting plate 18 against the upper surface of the first member 31, and the bottom end of the first threaded member 7 in the sleeve 321 is higher than the connecting pipe 322 and the discharging pipe 324.

[0033] After the first mounting plate 18 is locked to the sleeve 321 by the first threaded member 7, slurry is injected into the feed pipe 323 under pressure, so that the slurry fills the feed pipe 323, the sleeve 321, the connecting pipe 322, and the discharge pipe 324 in sequence. When the slurry overflows from the top end of the discharge pipe 324, the top ends of the discharge pipe 324 and the feed pipe 323 are blocked to solidify the slurry, so as to strengthen the connection between the sleeve 321 and the first threaded member 7.

[0034] Refer to Figure 2 and Figure 3 For the second casting body 4, the second casting body 4 includes a second member 41, a bottom plate 42, and a retaining wall 43. Both the bottom plate 42 and the retaining wall 43 are made of steel. The bottom plate 42 is in the shape of a square plate and the cross-sectional dimension is smaller than the cross-sectional dimension of the installation pit 2. The retaining wall 43 surrounds the bottom plate 42 along the circumferential direction of the bottom plate 42. The retaining wall 43 and the bottom plate 42 together form a casting cavity with an upward opening for casting the second member 41. The bottom plate 42 abuts against the upper surfaces of the second mounting plates 19 of the respective vibration isolation supports 5 at the same time. The second mounting plates 19 lock the bottom plate 42 through the second threaded members 8, and the retaining wall 43 does not contact the inner wall of the installation pit 2.

[0035] Furthermore, the steel support 6 includes four steel columns 62 extending vertically. Each steel column 62 has a base 61 at the bottom. The four steel columns 62 respectively correspond to the vibration isolation supports 5 at the four corners of the installation pit 2 one by one. The bases 61 of the steel columns 62 respectively abut against the upper surfaces at the four corners of the bottom plate 42. The second threaded members 8 on the vibration isolation supports 5 lock the corresponding steel columns 62 at the same time.

[0036] Refer to Figure 3 and Figure 4 Specifically, the second threaded member 8 includes a locking bolt 81 and a locking head 82. Second mounting holes for the rod portion of the locking bolt 81 to slide through are evenly spaced on the second mounting plate 19. Through holes corresponding to the second mounting holes one by one and for the rod portion of the locking bolt 81 to slide through are provided on the bottom plate 42. Through holes 20 for the rod portion of the locking bolt 81 to pass through are provided on the base 61, and the diameter of the through hole 20 is larger than the outer diameter of the rod portion of the locking bolt 81. The locking head 82 is threadedly sleeved on the rod portion of the locking bolt 81.

[0037] When the bottom plate 42 is installed with the steel support 6, the rod portion of the locking bolt 81 passes through the second mounting plate 19, the bottom plate 42 and the base 61 from bottom to top in sequence. Subsequently, the locking head 82 is threadedly sleeved on the locking bolt 81 and abuts against the surface of the base 61. It should be noted that the enlarged diameter of the through hole 20 relative to the rod portion of the locking bolt 81 enables fine adjustment of the position of the steel column 62 to improve the accuracy of the position of the steel column 62. After the vibration isolation support 5, the bottom plate 42 and the steel support 6 are all locked, concrete slurry is poured into the pouring cavity formed by the bottom plate 42 and the enclosure 43 to form the second component 41, and a steel reinforcement cage can be placed in the pouring cavity so that the second component 41 is a reinforced concrete structure.

[0038] Further, a circular locking ring 21 is also threadedly sleeved on the rod portion of the locking bolt 81 that cooperates with the base 61. The bottom surface of the bottom plate 42 has a relief cavity for the locking ring 21. After the rod portion of the locking bolt 81 passes through the second mounting plate 19, the locking ring 21 is first threadedly sleeved on the locking bolt 81 to limit the locking bolt 81, and then the bottom plate 42, the steel column 62 and the locking head 82 are installed in sequence.

[0039] Refer to Figure 1 and Figure 2 and, further, the steel support 6 is provided with a shielding member 9 extending opposite to the upper surface of the foundation base 1. The shielding member 9 is circumferentially distributed along the installation pit 2 to shield the gap between the foundation base 1 and the steel support 6 in the circumferential direction of the installation pit 2, so that sundries in the external environment are not easily fallen into the installation pit 2. And when there is no water accumulation in the external environment, there is a gap between the shielding member 9 and the foundation base 1, so that the vibration during the operation of the elevator is not easily transmitted to the foundation base 1 through the shielding member 9. And when there is water accumulation in the external environment, the shielding member 9 abuts against the foundation base 1 along the circumferential direction of the installation pit 2 to prevent the accumulated water on the foundation base 1 from entering the installation pit 2 through the gap between the shielding member 9 and the foundation base 1.

[0040] Refer to Figure 1 and Figure 5 and, specifically, the shielding member 9 includes an enclosure frame 91 and a hinge plate 92. The enclosure frame 91 is in a square shape and is fixedly sleeved on the four steel columns 62 at the same time. There are four hinge plates 92, and the four hinge plates 92 are all in a long strip shape and are respectively hinged to the four sides of the enclosure frame 91. The side of the hinge plate 92 away from the enclosure frame 91 extends to be opposite to the upper surface of the foundation base 1 close to the installation pit 2. An adjustment assembly is provided between the enclosure frame 91 and the hinge plate 92 to adjust the rotation angle of the hinge plate 92.

[0041] The adjustment assembly includes a moving frame 11, a telescopic power source 12, a guide rod 13, and a counterweight 14. Specifically, the moving frame 11 is in a square shape and is located in the installation pit 2. The moving frame 11 is simultaneously sleeved on four steel columns 62 and is located below the enclosing frame 91. The telescopic power source 12 is an electric telescopic rod. There are two telescopic power sources symmetrically arranged on the enclosing frame 91. The base end of the telescopic power source is installed on the enclosing frame 91. The telescopic end of the telescopic power source vertically penetrates through the enclosing frame 91 and is connected to the moving frame 11. When the telescopic end of the telescopic power source expands and contracts, it drives the moving frame 11 to move up and down relative to the steel support 6.

[0042] The top end of the guide rod 13 is hinged to the lower surface of the hinge plate 92. The hinge axis between the guide rod 13 and the hinge plate 92 is parallel to the hinge axis between the hinge plate 92 and the enclosing frame 91. The bottom end of the guide rod 13 vertically penetrates through the moving frame 11. The moving frame 11 is provided with moving holes 22 corresponding to the guide rods 13 one by one for the guide rods 13 to penetrate through. The cross-sectional dimension of the moving hole 22 is larger than the cross-sectional dimension of the guide rod 13 to be able to adapt to the rotation of the guide rod 13 relative to the hinge plate 92. The counterweight 14 corresponds to the guide rod 13 one by one and is fixed to the bottom end of the corresponding guide rod 13. The weight of the counterweight 14 gives the guide rod 13 and the hinge plate 92 a tendency to move downward.

[0043] When the telescopic end of the telescopic power source 12 retracts, the top surface of the moving frame 11 abuts against the bottom surface of the hinge plate 92, so that the moving frame 11 supports the hinge plate 92. At this time, there is an activity gap between the lower surface of the hinge plate 92 and the upper surface of the relative foundation 1, and at this time, the hinge plate 92 is in the first state.

[0044] When the telescopic end of the telescopic power source 12 extends downward, it drives the moving frame 11 to move downward until its lower surface abuts against the upper surface of the counterweight 14, and the moving frame 11 drives the counterweight 14 to move downward for a certain distance to drive the hinge plate 92 to rotate downward, so that the side of the hinge plate 92 away from the connecting plate abuts tightly against the upper surface of the foundation 1, and adjacent hinge plates 92 are connected in succession, so that the activity gap of the foundation 1 along the circumference of the installation pit 2 is closed. At this time, the hinge plate 92 is in the second state.

[0045] Refer to Figure 1 and Figure 5 , further, the upper surface of the foundation 1 near the installation pit 2 slopes upward along the direction close to the installation pit 2 to initially block the water flow, and a contact type water accumulation sensor (not shown in the figure) is embedded in the foundation 1. The sensor transmits a signal to the controller to control the expansion and contraction of the telescopic power through the controller, so that when there is water accumulation, the telescopic power can quickly adjust the hinge plate 92 to the second state.

[0046] Furthermore, a storage airbag 15 extending along the length direction of the hinge plate 92 is fixed to the bottom of the hinge plate 92. The storage airbag 15 is made of high-elastic rubber, and a plurality of air outlets 16 facing the movable gap are distributed along the length direction of the hinge plate 92 for blowing air into the movable gap. A contact strip 17 opposite to the storage airbag 15 is installed on the inner wall of the installation pit 2 of the foundation 1.

[0047] When the hinge plate 92 is in the first state, the storage airbag 15 is close to the contact strip 17, and at this time the storage airbag 15 is in a natural state. When the hinge plate 92 moves from the first state to the second state, the storage airbag 15 abuts against the contact strip 17 and is squeezed by the contact strip 17, so that the storage airbag 15 blows air into the movable gap through the air outlets 16 to blow out the impurities in the movable gap, and then the hinge plate 92 abuts tightly against the upper surface of the foundation 1.

[0048] In addition, in order to improve the stability of the elevator foundation, "X"-shaped support rods 23 are fixed between adjacent two steel columns 62, and the steel columns 62 are supported by the support rods 23, the enclosing frame 91 and the moving frame 11 together.

[0049] The implementation principle of the foundation fixing structure of an outdoor elevator in the embodiment of the present application is as follows: the first casting body 3 is fixed to the surrounding foundation 1, the second casting body 4 is fixed to the installation foundation steel bracket 6 of the elevator, and a vibration isolation support 5 is arranged between the first casting body 3 and the second casting body 4, so that the vibration generated during the operation of the elevator can be reduced by the vibration isolation support 5 and the shock absorption performance of the elevator can be improved.

[0050] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
