Description

Technical Field

[0001] This invention belongs to the field of elevator retrofitting technology, and specifically relates to a base-isolated elevator retrofitting structure and method for building energy-saving ventilation regulation. Background Technology

[0002] An elevator is a transportation device that vertically transports pedestrians or goods.

[0003] Currently, most elevator installations adopt an independent structural design or a hinged design with the original building structure as the mainstream design approach.

[0004] If the elevator is installed using an independent design, the size of the elevator's structural components will be much larger. If the elevator has a large number of floors, an independent design is not feasible. If the elevator is hinged to the original building, it will exert forces on the original building, requiring an assessment of the original structure.

[0005] Therefore, it is necessary to invent a base-isolated elevator installation structure and method for building energy-saving ventilation regulation to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a base-isolated elevator installation structure and method for building energy-saving ventilation regulation, thereby resolving the issues raised in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a base-mounted vibration-isolated elevator mounting structure for building energy-saving ventilation regulation, comprising an elevator, a vibration isolator at the bottom of the elevator, one side of the elevator being connected to a wall via multiple connecting devices, and a building energy-saving regulating ventilator at the top of the elevator;

[0008] The vibration isolator includes a support, which is a vibration isolation support. A groove is formed at the bottom of the support, and a base plate is slidably disposed within the groove. The bottom of the base plate has equidistant mounting openings, and ball bearings are rotatably mounted within these openings. A positioning component for positioning the base plate is provided on the support. Side plates are equidistantly and fixedly mounted around the top of the base plate. Sliding grooves are formed on the inner sides of the side plates. A bracket is slidably mounted between multiple sliding grooves. The bottom of the bracket is fixedly connected to the bottom wall of the sliding grooves via multiple springs. A positioning rod is rotatably mounted on the top of the bracket. A threaded hole is formed at the top of the base plate, and the bottom of the positioning rod has threads corresponding to the threaded hole. A clamping plate that mates with the ball bearings is fixedly mounted on the bottom of the bracket.

[0009] Furthermore, the base plate has multiple annular cavities inside, which are interconnected. The annular cavities correspond to the positions of the ball bearings. Multiple through-holes are provided between the annular cavities and the mounting ports. An oil injection component for injecting lubricating oil into the annular cavities is provided in the groove.

[0010] Furthermore, the oil injection assembly includes vertical grooves equidistantly arranged around the inner wall of the groove. A vertical block that mates with the vertical groove is fixedly installed on the outer side of the base plate. A plunger is fixedly installed on the top of the vertical block. A cavity is formed in the top wall of the vertical groove. The plunger extends into the cavity. The cavity is filled with lubricating oil. A liquid filling port communicating with the cavity is provided on the top wall of the support. A cover plate is provided inside the liquid filling port. The annular cavity and the cavity are connected by a hose.

[0011] Furthermore, the positioning component includes threaded posts threaded to the four corners of the top wall of the support, the bottom end of the threaded post extending into the groove, a gear fixedly installed on the top of the threaded post, a ring plate rotatably installed on the top wall of the support, teeth meshing with the gear on the outer side of the ring plate, and handles symmetrically fixedly installed on the top of the ring plate.

[0012] Furthermore, the bracket has an internal channel, a nozzle is provided between the channel and the clamp, a pipe is fixedly installed on the top of the support, and the bottom end of the pipe is connected to the channel through a telescopic tube.

[0013] Furthermore, the clamp is an arc-shaped clamp, and a rubber pad is provided at the bottom of the clamp.

[0014] Furthermore, the ball bearing is made of stainless steel.

[0015] The method for installing an elevator using the energy-saving ventilation and regulation base isolation elevator installation structure described above includes the following steps:

[0016] S1. When in use, the elevator is designed as a damper for the original building by setting the support at the bottom of the elevator and connecting the elevator to the building with the external connection device. This reduces the impact of horizontal forces on the original building and protects it.

[0017] S2. When installing the support, use a lifting device to place the support at the position to be installed. When it is necessary to adjust the position of the support, insert a tool into the cross-shaped reverse positioning rod to make it leave the threaded hole. The compressed spring release force will lift the bracket and clamping plate, causing the clamping plate to leave the ball bearings and cancel its fixation.

[0018] S3. The support can be pushed to move the ball bearings below. The ball bearings make it easy to move the entire support and adjust its position. After adjustment, the positioning rod is pressed down with a tool to lower the bracket and clamping plate. Then the positioning rod is rotated forward to enter the threaded hole, thus fixing the position of the bracket. The ball bearings are fixed by the friction between the clamping plate and the ball bearings.

[0019] S4. Then, the positioning component is removed from the base plate. Under the action of gravity, the support descends, allowing the ball bearings to enter the groove. At this time, the bottom of the support contacts the table surface at the installation location, making it easy to adjust the position of the support, saving time and effort, and meeting the installation requirements.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. When using this invention, the support is set at the bottom of the elevator and the elevator exterior is elastically connected to the building using a connecting device. The design concept of the elevator as a damper for the original building is adopted, thereby reducing the impact of horizontal forces on the original building and protecting it.

[0022] 2. The present invention facilitates the movement of the entire support by using ball bearings, thereby making it easy to adjust the position of the support. The ball bearings can be lubricated before movement to ensure smooth rotation, and the lubricating oil on the surface of the ball bearings can be cleaned after movement to prevent the lubricating oil from reducing the friction between the ball bearings and the clamping plate and affecting the fixation of the ball bearings. Furthermore, by fixing the ball bearings, the horizontal displacement of the support as a whole is prevented during the descent of the support, ensuring the accuracy of the adjustment results.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] This invention provides a base-isolated elevator mounting structure for building energy-saving ventilation regulation, such as... Figures 1 to 7 As shown, the elevator includes an elevator 1. The bottom of the elevator 1 is equipped with a vibration isolator 2. One side of the elevator 1 is connected to the wall through multiple connecting devices 3, which are vibration isolators. The top of the elevator 1 is equipped with a building energy-saving regulating ventilator 4, which is a fan. By opening the building energy-saving regulating ventilator 4, air can be blown into the elevator 1 to accelerate the internal air circulation and ensure the comfort of the staff.

[0033] The vibration isolator 2 includes a support 5, which is a vibration isolation support. The bottom of the support 5 has a groove, and a base plate 6 is slidably disposed in the groove. The bottom of the base plate 6 has equidistant mounting openings, and ball bearings 7 are rotatably installed in the mounting openings. The support 5 is provided with a positioning component for positioning the base plate 6. The top of the base plate 6 is equidistantly and fixedly mounted with side plates 8. The inner side of the side plates 8 has a sliding groove, and a bracket 9 is slidably mounted between multiple sliding grooves. The bottom of the bracket 9 is fixedly connected to the bottom wall of the sliding groove by multiple springs 10. A positioning rod 11 is rotatably mounted on the top of the bracket 9. The top of the support 5 has an opening that mates with the positioning rod 11. The top of the positioning rod 11 has a cross-shaped opening. The top of the base plate 6 has a threaded hole, and the bottom of the positioning rod 11 has a thread corresponding to the threaded hole. A clamping plate 12 that mates with the ball bearings 7 is fixedly mounted on the bottom of the bracket 9. The top of the support 5 is connected to the bottom of the elevator, and the bottom of the support 5 is connected to the installation location in the pit.

[0034] When in use, the elevator is installed at the bottom of the elevator by the support 5 and the elevator is connected to the building by the connecting device 3. The elevator is designed as a damper for the original building, thereby reducing the impact of horizontal forces on the original building and protecting it.

[0035] When installing support 5, a lifting device is used to place support 5 at the installation position. When the position of support 5 needs to be adjusted, a tool is inserted into the cross-shaped reversing positioning rod 11 to disengage it from the threaded hole. The compressed spring 10 releases its force, causing the bracket 9 and clamping plate 12 to rise, thus disengaging the clamping plate 12 from the ball bearing 7. This releases the clamping plate 12, allowing it to be pushed, enabling the lower ball bearing 7 to move. The ball bearing 7 facilitates the movement of the entire support 5, thereby enabling position adjustment. After completion, the positioning rod 11 is pressed down with a tool to lower the bracket 9 and clamp 12. Then, the positioning rod 11 is rotated forward to enter the threaded hole, thus fixing the position of the bracket 9. The friction between the clamp 12 and the ball bearing 7 can fix the ball bearing 7. Then, the positioning component is removed from the base plate 6. Under the action of gravity, the support 5 is lowered, allowing the ball bearing 7 to enter the groove. At this time, the bottom of the support 5 is in contact with the table surface at the installation location, making it easy to adjust the position of the support 5, saving time and effort, and meeting the installation requirements.

[0036] like Figures 4 to 5 As shown, the base plate 6 has multiple annular cavities 17 inside, which are interconnected. The annular cavities 17 correspond to the positions of the ball bearings 7. Multiple through ports 18 are provided between the annular cavities 17 and the mounting port. An oil injection component for injecting lubricating oil into the annular cavities 17 is provided in the groove.

[0037] In the initial state, the positioning component is a distance away from the base plate 6. When the support 5 is placed at the installation location, under the action of gravity, the support 5 descends and, together with the oil injection component, injects lubricating oil into the annular cavity 17. Subsequently, the lubricating oil enters each annular cavity 17 and finally enters the gap between the installation port and the ball 7 through the through port 18. Then, when the ball 7 rolls, it can lubricate the surface of the ball 7, making the ball 7 move more smoothly.

[0038] like Figure 5 As shown, the oil injection assembly includes vertical grooves equidistantly arranged around the inner wall of the groove. A vertical block 13 that mates with the vertical groove is fixedly installed on the outer side of the base plate 6. A plunger 15 is fixedly installed on the top of the vertical block 13. A cavity 14 is opened on the top wall of the vertical groove. The plunger 15 extends into the cavity 14. The cavity 14 is filled with lubricating oil. A liquid filling port communicating with the cavity 14 is provided on the top wall of the support 5. A cover plate is provided inside the liquid filling port. The annular cavity 17 is connected to the cavity 14 through a hose 16.

[0039] The lowering of the support 5 causes relative movement between the cavity 14 and the plunger 15, thereby squeezing the lubricating oil in the cavity 14 outward. The lubricating oil enters the annular cavity 17 through the hose 16, then enters each annular cavity 17, and finally enters the gap between the mounting port and the ball 7 through the port 18.

[0040] like Figures 3 to 5As shown, the positioning assembly includes threaded posts 19 threaded to the four corners of the top wall of the support 5. The bottom end of the threaded post 19 extends into the groove. A gear 20 is fixedly installed on the top of the threaded post 19. A ring plate 21 is rotatably installed on the top wall of the support 5. The outer side of the ring plate 21 is provided with teeth 22 that mesh with the gear 20. Handles are symmetrically fixedly installed on the top of the ring plate 21.

[0041] The forward rotation of the handle causes the ring plate 21 to rotate, which in turn drives the gear 20 to rotate the threaded column 19, causing the threaded column 19 to rise. This creates a gap between the bottom end of the threaded column 19 and the base plate 6, allowing the support 5 to descend. When the support 5 and the threaded column 19 descend to contact the base plate 6, the support 5 cannot move, and the base plate 6 cannot move, thus achieving the positioning of the base plate 6.

[0042] like Figure 5 As shown, the bracket 9 has a channel 23 inside, and a nozzle 24 is provided between the channel 23 and the clamp 12. A pipe 25 is fixedly installed on the top of the support 5, and the bottom end of the pipe 25 is connected to the channel 23 through a telescopic pipe 26.

[0043] Once the ball bearing 7 is lubricated and the position of the support 5 is adjusted, lubricating oil cleaning fluid can be injected into the channel 23 through the pipe 25 and the telescopic pipe 26. The lubricating oil cleaning fluid flows to the outside of the ball bearing 7 through the nozzle 24 and flows along the ball bearing 7 to clean the lubricating oil on the ball bearing 7. After completion, the clamping plate 12 can be combined with the ball bearing 7 to fix it. By cleaning the lubricating oil on the ball bearing 7, the friction between the ball bearing 7 and the clamping plate 12 can be avoided, thus avoiding affecting the fixation of the ball bearing 7. By fixing the ball bearing 7, the horizontal displacement of the support 5 as a whole can be avoided during the descent of the support 5, ensuring the accuracy of the adjustment result.

[0044] like Figure 5 As shown, the clamp 12 is an arc-shaped clamp, and a rubber pad is provided at the bottom of the clamp 12.

[0045] The rubber pads of the clamping plate 12 can increase the friction between the clamping plate 12 and the ball bearing 7, thereby improving the fixing effect of the ball bearing 7.

[0046] like Figure 5 As shown, the ball bearing 7 is made of stainless steel.

[0047] This makes the ball bearings 7 less prone to corrosion, ensuring they can rotate more smoothly.

[0048] The method for installing elevators using the energy-saving ventilation and regulation base isolation elevator installation structure described above includes the following steps:

[0049] S1. When in use, the elevator is designed as a damper for the original building by setting the support 5 at the bottom of the elevator and connecting the elevator to the building with the connecting device 3. This reduces the impact of horizontal forces on the original building and protects it.

[0050] S2. When installing the support 5, the support 5 is placed in the position to be installed by the lifting equipment. When the position of the support 5 needs to be adjusted, the tool is inserted into the cross-shaped reverse positioning rod 11 to make it leave the threaded hole. The compressed spring 10 releases its force and lifts the bracket 9 and the clamp 12, so that the clamp 12 leaves the ball 7 and the fixation is released.

[0051] S3. The support 5 can be pushed so that the lower ball bearing 7 can be moved. The ball bearing 7 makes it easy to move the entire support 5, thereby facilitating the adjustment of the position of the support 5. After the adjustment is completed, the positioning rod 11 is pressed down by the tool so that the bracket 9 and the clamping plate 12 are lowered. Then the positioning rod 11 is rotated forward so that it enters the threaded hole, thereby fixing the position of the bracket 9. The ball bearing 7 can be fixed by the friction between the clamping plate 12 and the ball bearing 7.

[0052] S4. Then, the positioning component is removed from the base plate 6. Under the action of gravity, the support 5 descends, allowing the ball bearing 7 to enter the groove. At this time, the bottom of the support 5 contacts the table surface at the installation location, making it easy to adjust the position of the support 5, saving time and effort, and meeting the installation requirements.

[0053] Working principle: When in use, the elevator is installed at the bottom of the elevator by the support 5 and the elevator is elastically connected to the building by the connecting device 3. The elevator is designed as a damper for the original building, thereby reducing the impact of horizontal forces on the original building and protecting it.

[0054] During the installation of support 5, a lifting device is used to place support 5 at the installation position. Due to the contact between the ball bearing 7 and the platform at the installation location, the ball bearing 7 cannot move, and the base plate 6 cannot move. Under the action of gravity, support 5, along with the threaded column 19, descends until it contacts the base plate 6. At this point, support 5 cannot move. During the descent of support 5, relative movement occurs between cavity 14 and plunger 15, thereby squeezing the lubricating oil in cavity 14 outward. The lubricating oil enters the annular cavity 17 through hose 16, then enters each annular cavity 17, and finally enters the gap between the installation port and the ball bearing 7 through the port 18. Subsequently, as the ball bearing 7 moves, it is lubricated, allowing it to move more smoothly. A tool is inserted into the cross-shaped reversing positioning rod 11 to disengage it from the threaded hole. The compressed spring 10 releases its force, causing the bracket 9 and clamping plate 12 to rise, disengaging the clamping plate 12 from the ball bearing 7. This releases the clamping plate, allowing the support 5 to be pushed, enabling the lower ball bearing 7 to move. The ball bearing 7 facilitates the movement of the entire support 5, making position adjustments easy. After adjustment, the positioning rod 11 is pressed down with a tool, causing the bracket 9 and clamping plate 12 to descend. Then, the positioning rod 11 is rotated forward. This allows the ball to enter the threaded hole, fixing the position of the bracket 9. The friction between the clamping plate 12 and the ball 7 secures the ball 7. Turning the handle forward rotates the ring plate 21, which in turn drives the gear 20 to rotate the threaded column 19, causing the threaded column 19 to rise. This creates a gap between the bottom of the threaded column 19 and the base plate 6, allowing the support 5 to descend and the ball 7 to enter the groove. At this point, the bottom of the support 5 contacts the surface of the installation area, facilitating easy adjustment of the support 5's position. This saves time and effort, meeting installation requirements. Throughout the process, the securing of the ball 7 ensures that the support... During the descent of support 5, horizontal displacement of support 5 as a whole is avoided, ensuring the accuracy of the adjustment result. After the ball bearing 7 is lubricated and the position of support 5 is adjusted, lubricating oil cleaning fluid can be injected into channel 23 through pipe 25 and telescopic pipe 26. The lubricating oil cleaning fluid flows to the outside of ball bearing 7 through nozzle 24 and flows along ball bearing 7 to clean the lubricating oil on ball bearing 7. After completion, clamp 12 can be combined with ball bearing 7 to fix it. By cleaning the lubricating oil on ball bearing 7, the lubricating oil can be prevented from reducing the friction between ball bearing 7 and clamp 12, thus avoiding affecting the fixation of ball bearing 7.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
