Description

Technical Field

[0001] This invention relates to the field of elevator installation technology, specifically to an elevator shaft module installation device and method. Background Technology

[0002] In traditional modular elevator shaft installation, the need to hoist large components necessitates the use of heavy-duty cranes for vertical transportation on construction sites. Crane operating radii typically need to cover a large area and require a certain level of ground bearing capacity, while also necessitating ample temporary storage areas for shaft module turnover. This spatial requirement presents a significant contradiction with the renovation scenarios of older residential communities, where dense underground pipelines and complex geological conditions make it difficult to meet the site requirements of traditional hoisting techniques. Furthermore, the high and prolonged noise pollution generated by hoisting operations further exacerbates the conflict with residents' daily lives, becoming a key technical bottleneck hindering the advancement of elevator installation projects in older residential communities. Summary of the Invention

[0003] In order to overcome the problems existing in the prior art, the purpose of this invention is to provide an elevator shaft module installation device.

[0004] The technical solution adopted by this invention to solve its technical problem is: an elevator shaft module installation device, comprising: Support frame, lifting device, stop support device, and guide device; The support frame is erected on the periphery of the elevator shaft, and one side of the support frame is provided with an opening for the shaft module to enter. The lifting device is installed inside the elevator shaft, the support frame is detachably connected to the ground foundation, and the lifting device is equipped with a connection unit that cooperates with the shaft module and a lifting unit that lifts the shaft module to a specified height. The stop support device is installed on the side wall of the support frame. The stop support device is equipped with a telescopic support block. When the hoistway module is being lifted, the telescopic support block retracts to facilitate the passage of the hoistway module. When the hoistway module is lifted to a specified height, the telescopic support block extends to support and fix the hoistway module. The guiding device is located inside the support frame and guides the well module. Main working principle: An elevator shaft module installation device, including a support frame, a lifting device, a stop support device and a guide device.

[0005] The rectangular steel support frame is erected longitudinally along the perimeter of the elevator shaft and rigidly connected to the ground foundation using expansion bolts or embedded parts to ensure stable installation. The support frame is installed in sections, allowing for stacking of its height as needed. The side openings of the support frame are aligned with the module transport channel, with the opening size larger than the outer contour of the shaft module to allow for operational space. A forklift will then deliver the shaft module above the shaft. A lifting device is fixed to the base at the bottom of the shaft using bolts or embedded parts. Its connecting unit connects to the pre-drilled mounting holes on the shaft module. The lifting unit is equipped with a synchronous hydraulic lifting system, enabling the lifting of the shaft module. The shaft module is then horizontally moved into the support frame through the opening, activating the connecting unit of the lifting device. The guide device contacts the side of the shaft module to eliminate any horizontal offset.

[0006] Once the module is raised to the preset installation height, the lifting device pauses operation. At this point, the space at the bottom of the hoistway module can accommodate another hoistway module. The telescopic support block of the stop support device extends outward, contacting the bottom of the hoistway module to temporarily support and fix it. After confirming that the stop support device is locked, the lifting device slowly releases the load and removes the connecting unit from the hoistway module, completing the installation of the above hoistway module and allowing the installation of the next hoistway module to continue.

[0007] The application of the support frame and jacking device eliminates the dependence on hoisting equipment, making it suitable for renovation scenarios in old residential areas with narrow shafts.

[0008] Preferably, the lifting unit includes a first base and a lifting rod; The first base is fixedly connected to the elevator shaft, the lifting rod is perpendicular to the horizontal plane, and one end of the lifting rod is fixedly connected to the first base by bolts or embedded parts, and the other end of the lifting rod is connected to the connecting unit.

[0009] Preferably, the end of the lifting rod that is connected to the connecting unit is provided with a bayonet, and the connecting unit is engaged in the bayonet.

[0010] Preferably, the lifting rod has at least two rods, which are arranged in parallel and are respectively connected to the connecting unit.

[0011] Preferably, the connecting unit includes a connecting rod, which is connected to the lifting unit and is parallel to the horizontal plane. The connecting rod passes through both sides of the shaft module and connects to the shaft module.

[0012] Preferably, the stop support device further includes a second base and a spring-loaded component; The second base is installed on one side of the support frame, and the telescopic support block is connected to the second base via a pivot; one end of the spring-loaded component is connected to the second base, and the other end of the spring-loaded component is connected to the side of the telescopic support block facing away from the shaft module.

[0013] Preferably, the stop support device further includes a limiting block, which is disposed on the side of the telescopic support block facing away from the wellbore module. When the telescopic support block supports the wellbore module, the limiting block and the second base are mutually pressed together and limited.

[0014] Preferably, the guiding device includes a roller and a third base, the third base is installed inside the support frame, the roller is connected to the pivot of the third base, and the roller makes rolling contact with the well module.

[0015] Preferably, there are four or eight rollers and three third bases. The rollers and each third base are arranged on the same horizontal plane. The three third bases are respectively installed at the four corners or four horizontal crossbars inside the support frame. The rollers can be adjusted by adjusting the horizontal extension distance and horizontal deflection angle to facilitate cooperation with the outer wall of the elevator shaft module. The rollers are respectively installed in the third bases, and each roller is provided with a groove. The grooves cooperate with the corners of the shaft module.

[0016] An elevator shaft module installation method, using any of the elevator shaft module installation devices described above, includes the following steps: S1. Erect the support frame around the elevator shaft, ensuring the opening direction facilitates the entry of the shaft module; check the lifting device, stop support device, and guide device to ensure that each device is in normal working condition; transport the shaft module to the vicinity of the elevator shaft and adjust it to a suitable position so that it is aligned with the opening of the support frame. S2. Use a forklift to lift the shaft module to the opening of the support frame, and slowly push the shaft module forward so that it is aligned with the elevator shaft under the guidance of the guide device; the rollers of the guide device make rolling contact with the shaft module to initially guide the shaft module; S3. After the hoistway module enters a certain depth in the hoistway, connect the connecting unit of the lifting device to the hoistway module; the connecting rod of the connecting unit passes through both sides of the hoistway module and is tightly connected to the hoistway module. At the same time, the connecting rod is engaged with the lifting rod of the lifting unit through a bayonet. S4. Start the lifting device. The lifting rod of the lifting unit extends vertically upward, driving the connecting unit and the hoistway module to be lifted together. During the lifting process, the telescopic support block of the stop support device is in a retracted state so that the hoistway module can pass smoothly. The guide device continuously guides the hoistway module to ensure that the hoistway module is lifted vertically and does not deviate. S5. Disconnect the connection unit from the shaft module, pull the connecting rod out from both sides of the shaft module; restore the lifting device, stop support device and guide device to their initial state, and begin the installation of the next shaft module.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention, through its innovative design of external support frame and coordinated operation of forklift transfer and lifting device, completely abandons the traditional crane high-altitude lifting mode, greatly reducing the space occupied by the equipment, perfectly adapting to the narrow construction environment of old residential areas, significantly shortening the installation cycle, and reducing the noise caused by large hoisting equipment. It significantly improves construction efficiency and residents' acceptance, providing an efficient, safe, and environmentally friendly breakthrough solution for elevator installation in old residential areas during urban renewal.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Example 1 This embodiment discloses an elevator shaft module installation device, such as... Figures 1-4 As shown, it includes a support frame 1, a lifting device 2, a stop support device 3, and a guide device 4.

[0023] The rectangular steel support frame 1 is erected longitudinally along the periphery of the elevator shaft 5, and rigidly connected to the ground foundation using expansion bolts or embedded parts to ensure stable installation. The opening 10 on the side wall of the frame is aligned with the module transport channel, and its size is larger than the outer contour of the shaft module 6 to allow for operating space. A forklift will then transport the shaft module 6 above the shaft. A lifting device 2 is fixed on the base at the bottom of the shaft, and its connecting unit 20 connects to the reserved mounting holes of the shaft module 6. The lifting unit 21 is equipped with a hydraulic synchronous lifting system, which can lift the shaft module 6. The shaft module 6 is horizontally moved into the support frame 1 through the opening 10, and the connecting unit 20 of the lifting device 2 is activated. The guide device 4 contacts the side of the shaft module 6 to eliminate horizontal offset.

[0024] When the module is raised to the preset installation height, the lifting device 2 stops operating. At this time, the space at the bottom of the shaft module 6 can accommodate another shaft module 6. The telescopic support block 30 of the stop support device 3 extends outward and contacts the bottom of the shaft module 6 to temporarily support and fix the shaft module 6. After confirming that the stop support device 3 is locked, the lifting device 2 slowly releases the load and removes the connecting unit 20 from the shaft module 6, completing the installation of the shaft module 6 and allowing the installation of the next shaft module 6 to continue.

[0025] The application of the support frame 1 and the lifting device 2 eliminates the dependence on hoisting equipment and is suitable for the renovation of old residential areas with narrow shafts.

[0026] In some optional embodiments, it is fixedly connected to the elevator shaft 5 to provide a stable mounting base for the lifting unit 21, ensuring that the lifting unit 21 remains in a fixed position during operation. The lifting rod 211 is perpendicular to the horizontal plane, with one end connected to the first base 210 and the other end connected to the connecting unit 20. By extending or shortening itself, it enables the vertical movement of the connecting unit 20 and the shaft module 6 connected to the connecting unit 20, thus completing the lifting action. Specifically, the lifting rod 211 can be a hydraulic rod, providing sufficient support during the lifting process.

[0027] In some optional embodiments, the bayonet 212 is located at the end where the lifting rod 211 connects to the connecting unit 20, and the connecting unit 20 is snapped into the bayonet 212. This connection method makes it easier to connect and disconnect the connecting unit 20 and the lifting rod 211, while ensuring the stability of the connection to a certain extent, facilitating the transmission of force during the jacking process and driving the hoistway module 6 to rise.

[0028] In some optional embodiments, two lifting rods 211 are arranged in parallel and connected to the connecting unit 20 respectively. Compared with a single lifting rod 211, the weight of the shaft module 6 can be distributed more evenly, providing a more stable lifting force, reducing instability caused by uneven force, and improving the safety and reliability of the lifting process.

[0029] In some optional embodiments, the connecting rod 200 is connected to the lifting unit 21 and kept parallel to the horizontal plane, passing through both sides of the shaft module 6 and connecting to the shaft module 6. This connection method can firmly connect the shaft module 6 and the lifting unit 21 together, so that the lifting force of the lifting unit 21 can be effectively transmitted to the shaft module 6, driving the shaft module 6 to rise, while ensuring that the force on the connection part is uniform.

[0030] In some optional embodiments, the second base 31 is installed on one side of the support frame 1, providing a mounting base for the telescopic support block 30 and the spring-loaded member 32, and determining the position of the stop support device 3 on the support frame 1. The telescopic support block 30 is connected to the second base 31 via a pivot, allowing it to rotate around the pivot to achieve retraction and extension. During the lifting process of the shaft module 6, it retracts to facilitate the passage of the shaft module 6, and extends to support the shaft module 6 after being lifted into position. One end of the spring-loaded member 32 is connected to the second base 31, and the other end is connected to the side of the telescopic support block 30 facing away from the shaft module 6. During the ascent of the shaft module 6, the shaft module 6 pushes the telescopic support block 30 outward. At this time, the telescopic support block 30 rotates outward along the pivot, simultaneously pulling the spring-loaded member 32. When the shaft module 6 rises to the designated height, the elastic force of the spring-loaded member 32 automatically pushes the telescopic support block 30 outward to support the shaft module 6, simplifying the operation process.

[0031] In some optional embodiments, the limiting block 33 is disposed on the side of the telescopic support block 30 facing away from the hoistway module 6. When the telescopic support block 30 supports the hoistway module 6, the limiting block 33 and the second base 31 are mutually pressed and limited. This prevents the telescopic support block 30 from excessively extending or rotating when bearing the weight of the hoistway module 6, ensuring the stability and reliability of the telescopic support block 30 in supporting the hoistway module 6, and avoiding safety accidents such as the hoistway module 6 falling due to changes in the position of the telescopic support block 30.

[0032] In some optional embodiments, a third base 41 is mounted inside the support frame 1, providing a mounting position for the roller 40 and determining the layout of the roller 40 on the support frame 1, enabling the roller 40 to accurately contact the shaft module 6 and provide guidance. The roller 40 is pivotally connected to the third base 41 and makes rolling contact with the shaft module 6. During the entry and lifting of the shaft module 6, the roller 40 reduces the resistance to movement of the shaft module 6 by using rolling friction instead of sliding friction, while simultaneously guiding the shaft module 6 to move in the correct direction.

[0033] In some optional embodiments, four or eight third bases 41 are respectively installed at the four corners of the inner side of the support frame 1, and four or eight rollers 40 are respectively installed inside the four or eight third bases 41. This layout can guide the shaft module 6 from four directions, ensuring the stability of the shaft module 6 during entry into the shaft and lifting process, and preventing the shaft module 6 from tilting or deviating. At the same time, every four third bases 41 and four rollers 40 form a layer, with no less than one layer. The number of layers can be increased vertically as needed to accommodate a higher support frame 1. Each of the four rollers 40 is provided with a groove 42, which cooperates with the corners of the shaft module 6. This design can more accurately position and guide the shaft module 6, ensuring that the shaft module 6 runs strictly along a predetermined trajectory during movement, further improving installation accuracy.

[0034] Example 2 An elevator shaft module installation method, using the elevator shaft 5 module installation device of Embodiment 1, the method as follows: Figures 5-7 As shown, it includes the following steps: S1. Erect the support frame 1 around the elevator shaft 5, ensuring that the direction of the opening 10 is convenient for the shaft module 6 to enter; check the lifting device 2, the stop support device 3 and the guide device 4 to ensure that each device is in normal working condition; transport the shaft module 6 to the vicinity of the elevator shaft 5 and adjust it to a suitable position so that it is aligned with the opening 10 of the support frame 1. S2. The hoisting module 6 is lifted to the opening 10 of the support frame 1 by a forklift, and the hoisting module 6 is slowly lowered so that it enters the elevator shaft 5 smoothly under the guidance of the guide device 4; the rollers 40 of the guide device 4 make rolling contact with the hoisting module 6 to initially guide the hoisting module 6. S3. When the shaft module 6 enters the shaft to a certain depth, the connecting unit 20 of the lifting device 2 is connected to the shaft module 6. The connecting rod 200 of the connecting unit 20 passes through both sides of the shaft module 6 and is tightly connected to the shaft module 6. At the same time, the connecting rod 200 is engaged with the lifting rod 211 of the lifting unit 21 through the bayonet 212. S4. Start the lifting device 2. The lifting rod 211 of the lifting unit 21 extends vertically upward, driving the connecting unit 20 and the shaft module 6 to be lifted together. During the lifting process, the telescopic support block 30 of the stop support device 3 is in a retracted state so that the shaft module 6 can pass smoothly. The guide device 4 continuously guides the shaft module 6 to ensure that the shaft module 6 is lifted vertically and does not deviate. S5. Disconnect the connection unit 20 from the shaft module 6, and pull out the connecting rod 200 from both sides of the shaft module 6; restore the lifting device 2, the stop support device 3 and the guide device 4 to their initial state, and begin the installation of the next shaft module 6.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
