Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to a method for retrofitting elevators into old buildings. Background Technology
[0002] Adding elevators to old buildings is a beneficial measure for existing multi-story residential buildings that were built a long time ago and do not have elevators. It aims to facilitate the travel of residents, especially the elderly and people with mobility difficulties, and improve their quality of life. The process involves a series of procedures, including approval from relevant departments and consultation with residents. Funds are raised through various means, such as self-financing by homeowners, applying for government subsidies, or introducing social capital. Elevators are then added to suitable locations on the exterior of the existing buildings in accordance with certain planning, design, and construction standards.
[0003] A search revealed Chinese Patent Publication No. CN214330022U, which discloses a method for retrofitting elevators in old residential buildings, belonging to the technical field of elevator retrofitting in old residential buildings. The key technical points include a car located on the outside of the residential building, a traction mechanism for driving the car's vertical movement, and multiple hoisting columns for sliding support of the car. The residential building includes exterior walls, rest platforms, entrance platforms, resident doors, ascending stairs, descending stairs, and unit door canopies. Multiple interlocking mechanisms are provided between the exterior walls and the hoisting columns. Furthermore, each even-numbered floor on the exterior walls has an entrance corresponding to the car door and matching its size, leading to the rest platform. This type of elevator retrofitting in old residential buildings operates safely and stably, and significantly reduces the number of entrance openings, saving manpower, resources, and time required for elevator installation. However, because the elevator is a later addition, its safety in older buildings is insufficient, leading to instability and increased safety risks. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a method for adding elevators to old buildings, aiming to improve the problem that the safety of elevators added to old buildings is insufficient due to the fact that the elevators are added later, which in turn leads to insufficient stability and increased safety risks.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an elevator for adding an elevator to an old building, comprising multiple columns, with a horizontal steel beam fixedly connected to one side of two adjacent columns, a fixed plate fixedly connected to the middle of the right side of each column, a motor installed on the top of the front horizontal steel beam, and fixed square plates fixedly connected to the top of each of the two horizontal steel beams. A rotating rod is fixedly connected to the output end of the motor, the rear side of the rotating rod passes through the front fixed square plate and is rotatably connected to the rear fixed square plate, pulleys are fixedly connected to the front and rear ends of the outer side of the rotating rod, and steel wire ropes are installed on the outer side of each pulley. A car is provided at the bottom of the steel wire rope, and a fixing mechanism is installed on the top of the car. The fixing mechanism is used to fix the car and the steel wire rope.
[0006] The above technical solution ensures vertical stability by using the vertical support column as the elevator's vertical support component. The horizontal steel beams connect and reinforce the column, making the frame more robust. The motor drives the rotating rod and pulley to rotate, which in turn drives the steel wire rope to move up and down, thereby meeting the travel needs of residents, improving the stability and safety of the device, and extending its service life.
[0007] As a further description of the above technical solution:
[0008] The fixing mechanism includes a mounting circular plate, which is fixedly connected to the bottom end of the wire rope. Mounting plates are slidably connected to the front and rear ends of the top of the car. A T-slot is opened on the top of the mounting plate, and the interior of the T-slot is slidably connected to the mounting circular plate. A rotating short column is rotatably connected to the adjacent side of the top of the two mounting circular plates. A first locking plate is fixedly connected to the front side of the rear rotating short column, and a second locking plate is fixedly connected to the rear side of the front rotating short column. The first locking plate and the second locking plate are slidably connected.
[0009] The above technical solution involves fixing a circular mounting plate to the bottom of the wire rope, providing a sliding mounting plate on the top of the car, and using a T-slot to allow the circular mounting plate to slide, accommodating minor displacement and swaying of the car. When fixing the car and wire rope, the circular mounting plate is slid into the appropriate position in the T-slot, and the short columns on both sides are rotated to gradually engage the first and second locking plates, thus achieving the fixing effect. When disassembly and maintenance are required, the short columns are rotated in the opposite direction to disengage the locking plates, allowing the circular mounting plate to be removed, separating the car from the wire rope, and ensuring the safe operation of the elevator.
[0010] As a further description of the above technical solution:
[0011] A handle is fixedly connected to the top of the rotating short column, and a protective cover is installed on the outside of the handle.
[0012] The above technical solution facilitates the rotation of the short column by installing a handle.
[0013] As a further description of the above technical solution:
[0014] The rotating short column is equipped with fixing blocks at both ends. A locking rod is fixedly connected to the middle of the left fixing block, and the right side of the locking rod engages with the right fixing block.
[0015] The above technical solution, through the installation of the locking rod, prevents unnecessary rotation of the rotating short column.
[0016] As a further description of the above technical solution:
[0017] A fixed plate is installed on one side of the top of the column, and a second screw is threaded to each of the four corners of the fixed plate.
[0018] The above technical solution makes the installation of the column and the horizontal steel beam more stable by fixing the long plate.
[0019] As a further description of the above technical solution:
[0020] The top of each column is threaded with a first screw on the other side.
[0021] The above technical solution makes the device more secure by installing the first screw.
[0022] As a further description of the above technical solution:
[0023] The front and rear ends of the left side of the fixed plate are fixedly connected to sliding blocks, and the front and rear ends of the right side of the car are fixedly connected to sliders. The right side of the slider is slidably connected to the inside of the sliding block.
[0024] The above technical solution, through the installation of sliders and chute blocks, makes the car run more smoothly.
[0025] As a further description of the above technical solution:
[0026] A slot plate is fixedly connected to the rear left side of the top of the car, and a notice board is installed inside the slot plate.
[0027] The above technical solution allows for the installation of notice boards to remind staff.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, the column serves as the vertical support component of the elevator to ensure vertical stability. The horizontal steel beam connects and reinforces the column to make the frame more robust. The motor drives the rotating rod and pulley to rotate, which in turn drives the steel wire rope to move, thereby pulling the car up and down to meet the travel needs of residents, improve the stability and safety of the device, and extend its service life.
[0030] 2. In this utility model, the mounting circular plate is fixed to the bottom end of the wire rope, and a sliding mounting plate is provided on the top of the car. The T-slot allows the mounting circular plate to slide, adapting to the slight displacement and swaying of the car. When fixing the car and the wire rope, the mounting circular plate is slid into the appropriate position of the T-slot, and the short columns on both sides are rotated to make the first locking plate and the second locking plate gradually lock together to achieve the fixing effect. When disassembly and maintenance are required, the short columns are rotated in the opposite direction to make the locking plates disengage, and the mounting circular plate can be removed to separate the car and the wire rope, ensuring the safe operation of the elevator.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an elevator installation for an old building, comprising multiple columns 1. A transverse steel beam 7 is fixedly connected to one side of adjacent sides of two columns 1. A fixing plate 3 is fixedly connected to the middle of the right side of each column 1. A motor 8 is installed on the top of the front transverse steel beam 7, providing power to subsequent processes. A fixing square plate 11 is fixedly connected to the top of each of the two transverse steel beams 7. A rotating rod 9 is fixedly connected to the output end of the motor 8. The rear side of the rotating rod 9 passes through the front fixing square plate 11 and rotates with the rear fixing square plate 11. Next, pulleys 12 are fixedly connected to the front and rear ends of the outer side of the rotating rod 9. Steel wire ropes 14 are installed on the outer side of the pulleys 12. A car 13 is set at the bottom of the steel wire rope 14. The installation of the steel wire rope 14 allows the car 13 to move up and down. A fixing mechanism 2 is installed on the top of the car 13. The fixing mechanism 2 is used to fix the car 13 and the steel wire rope 14. A fixing plate 5 is installed on one side of the top of the column 1. The four corners of the fixing plate 5 are threaded with second screws 6. The other side of the top of the column 1 is threaded with first screws 4.
[0040] Specifically, firstly, multiple columns 1 serve as vertical support components for the entire elevator structure, ensuring its stability in the vertical direction. Two adjacent columns 1 are connected by a transverse steel beam 7 fixed on one side, which not only connects the adjacent columns 1 but also enhances the stability of the entire frame structure, enabling it to withstand the forces generated by the car 13 during operation. With the motor 8 activated, since the output end of the motor 8 is connected to the rotating rod 9, the rear end of the rotating rod 9 can pass through the front fixed square plate 11 and rotatably connect to the rear fixed square plate 11. The pulleys 12, fixedly connected to the front and rear ends of the rotating rod 9, rotate synchronously with the drive of the motor 8. The steel wire rope 14 installed on the outside of the pulley 12 begins to move under the drive of the pulley 12. The movement of the steel wire rope 14 is converted into a traction force on the car 13 because the bottom of the steel wire rope 14 is equipped with a car 13. When the motor 8 rotates in the forward direction, the car 13 will be lifted upward through the transmission of the pulley 12 and the steel wire rope 14, realizing the transportation of residents to the upper floors. Conversely, when the motor 8 rotates in the reverse direction, the car 13 will run downward under the traction of the steel wire rope 14, completing the process of going downstairs. In this way, the elevator device can meet the needs of residents to travel conveniently between different floors, while improving the stability and safety of the device and extending its service life. The installation of the fixed long plate 5 makes the installation of the column 1 and the transverse steel beam 7 more stable. The installation of the first screw 4 makes the installation of this device more stable.
[0041] Reference Figure 1 , Figure 3 and Figure 5The fixing mechanism 2 includes a mounting circular plate 203, which is fixedly connected to the bottom end of the wire rope 14. Mounting plates 201 are slidably connected to the front and rear ends of the top of the car 13. A T-slot 202 is provided on the top of the mounting plate 201, allowing the mounting circular plate 203 to be removed. The interior of the T-slot 202 is slidably connected to the mounting circular plate 203. A rotating short column 204 is rotatably connected to the adjacent top sides of the two mounting circular plates 203. A first rotating short column 204 is fixedly connected to the front side of the rear rotating short column 204. A first locking plate 205 is fixedly connected to the rear side of the front rotating short column 204, and a second locking plate 206 is fixedly connected to the rear side of the first locking plate 205 and the second locking plate 206 are slidably connected. A handle 18 is fixedly connected to the top of the rotating short column 204, and a protective sleeve 19 is installed on the outside of the handle 18. The installation of the protective sleeve 19 prevents the handle 18 from being damaged. Fixing blocks 20 are installed on both the left and right ends of the rotating short column 204. A locking rod 21 is fixedly connected to the middle of the left fixing block 20, and the right side of the locking rod 21 is locked with the right fixing block 20.
[0042] Specifically, the mounting plate 203 is fixedly connected to the bottom end of the wire rope 14, while the front and rear ends of the top of the car 13 are provided with sliding mounting plates 201. The top of these mounting plates 201 is provided with T-slots 202, which allows the mounting plate 203 to slide freely in the T-slots 202. This allows the device to adapt to the small displacements and swaying generated during the operation of the car 13, thereby achieving a preliminary fixed connection. By rotating the two rotating short columns 204, the first locking plate 205 and the second locking plate 206 connected to them are driven to lock together. When it is necessary to fix the car 13 to the wire rope 14, the mounting plate 203 is first slid into the appropriate position of the T-slot 202, and then the rotating short column 204 on the rear side is rotated to make the first locking plate 205 rotate. Simultaneously, rotating the front rotating short column 204 causes the second locking plate 206 to rotate backward. As the rotation proceeds, the first locking plate 205 and the second locking plate 206 will gradually engage until they are completely fixed, thus ensuring that the car 13 will not detach from the wire rope 14 during operation and ensuring the safe operation of the elevator. When the car 13 needs to be disassembled for maintenance or other operations, simply rotate the rotating short column 204 in the opposite direction to disengage the first locking plate 205 from the second locking plate 206, and the mounting circular plate 203 can be removed from the T-slot 202, thereby separating the car 13 from the wire rope 14. The installation of the handle 18 facilitates the rotation of the rotating short column 204, and the installation of the locking rod 21 prevents unnecessary rotation of the rotating short column 204.
[0043] Reference Figure 1 , Figure 2 and Figure 3The front and rear ends of the left side of the fixed plate 3 are fixedly connected with sliding block 10, and the front and rear ends of the right side of the car 13 are fixedly connected with slider 17. The right side of slider 17 is slidably connected to the inside of sliding block 10. The rear end of the left side of the top of the car 13 is fixedly connected with slot plate 15, and a notice board 16 is installed inside the slot plate 15.
[0044] Specifically, the installation of slider 17 and slide block 10 makes the car 13 run more smoothly, and the installation of notice board 16 makes it easier to remind staff.
[0045] Working principle: First, multiple columns 1 serve as vertical support components for the entire elevator structure, ensuring its vertical stability. A transverse steel beam 7, fixedly connected to the adjacent sides of two columns 1, connects and reinforces adjacent columns 1, making the entire frame structure more robust and able to withstand the forces generated by the car 13 during operation. When the motor 8 is activated, the output end of the motor 8 is connected to a rotating rod 9. The rear side of the rotating rod 9 can penetrate the front fixed square plate 11 and rotatably connect to the rear fixed square plate 11. Pulleys 12, fixedly connected to the front and rear ends of the outer side of the rotating rod 9, rotate as the motor 8 drives the rotating rod 9 to rotate. 12 also rotates synchronously, and the steel wire rope 14 installed on the outside of the pulley 12 starts to move under the drive of the pulley 12. Since the car 13 is set at the bottom of the steel wire rope 14, the movement of the steel wire rope 14 is converted into a traction force on the car 13. When the motor 8 rotates in the forward direction, the car 13 will be lifted upward through the transmission of the pulley 12 and the steel wire rope 14 to realize the transportation of residents upstairs; when the motor 8 rotates in the reverse direction, the car 13 will run downward under the traction of the steel wire rope 14 to complete the process of going downstairs. This meets the needs of residents for convenient travel between different floors, improves the stability and safety of the device, and extends its service life.
[0046] The mounting plate 203 is fixedly connected to the bottom end of the wire rope 14. Sliding mounting plates 201 are provided at the front and rear ends of the top of the car 13. A T-slot 202 is formed at the top of the mounting plate 201, allowing the mounting plate 203 to slide within the T-slot 202. This allows the device to adapt to minor displacements and swaying during the operation of the car 13, serving as a preliminary fixing connection. Rotating short columns 204 are rotatably connected to adjacent sides of the top of the two mounting plates 203. A first engaging plate 205 is fixedly connected to the front of the rear rotating short column 204, and a second engaging plate 206 is fixedly connected to the rear of the front rotating short column 204, allowing the two to engage. When it is necessary to fix the car 13 to the wire rope 14, the mounting plate 203 is first slid into the appropriate position along the T-slot 202. Next, rotate the rear rotating short column 204, causing the first locking plate 205 to rotate. At the same time, rotate the front rotating short column 204, causing the second locking plate 206 to rotate backward. As the rotation process proceeds, the first locking plate 205 and the second locking plate 206 will gradually lock into each other, eventually locking completely and fixing the mounting plate 203 between the two mounting plates 201. This achieves the fixation of the car 13 and the wire rope 14, ensuring that the car 13 will not detach from the wire rope 14 during operation and guaranteeing the safety of elevator operation. When it is necessary to disassemble the car 13 for maintenance or other operations, rotate the rotating short column 204 in the opposite direction to disengage the first locking plate 205 and the second locking plate 206. Then, the mounting plate 203 can be removed from the T-slot 202, completing the separation of the car 13 and the wire rope 14.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
