Description

Technical Field

[0001] The invention relates to the technical field of building construction machinery, and in particular to a containment construction system. Background Art

[0002] During the construction of a nuclear power plant, the nuclear island building (i.e., the inner building, also known as the containment) is the core part of the nuclear power plant, which contains key equipment such as the reactor and steam generator. The main structure of the containment is usually cast with high-strength concrete to ensure that the containment can provide sufficient structural strength to protect the internal equipment. The containment is usually divided into a cylindrical structure and a hemispherical dome structure. The cylindrical structure is perpendicular to the ground and forms a 90-degree angle with the horizontal plane. The buttresses are set in the containment and protrude from the shell wall, and the buttresses extend to the hemispherical dome. The function of the buttresses is to anchor the horizontal prestressed steel bundles of the containment.

[0003] In order to enhance the safety and stability of the containment concrete structure, prestressed tensioning technology is usually used to apply pre-compressive stress before the containment structure is subjected to external loads, thereby improving the bending resistance and rigidity of the structure and increasing the durability of the structure. During the prestressed tensioning construction of the containment, a working platform for installing tensioning equipment such as jacks needs to be built along the facade of the containment buttresses to ensure that the staff can perform tensioning operations safely and effectively. Prior to this, it is necessary to pre-assemble guide rails for the movement of the working platform on the facade of the buttresses of the containment. In the existing construction platform, the guide rails are usually fixed to the buttresses of the containment only through embedded parts and two are arranged at intervals along the lateral direction. Specifically, the guide rails of the buttresses arranged on the cylinder of the containment are perpendicular to the horizontal plane, and the guide rails of the buttresses arranged on the hemispherical dome of the containment are arranged along the curved surface of the hemispherical dome.

[0004] The Chinese utility model patent with announcement number CN211548700U discloses a prestressed construction platform for an inner factory building, including two guide rails installed along the facade of the inner factory building buttresses, on which a construction operation platform is installed through a lifting drive device, which moves up and down along the guide rails; the guide rails are also equipped with a hoist device that slides along them and is independent of the construction operation platform.

[0005] However, the prestressed construction platform in the inner factory building in the above-mentioned prior art has difficulty in adapting to the curvature change of the guide rail when the hoist device and the construction operation platform rise along the guide rail of the containment cylinder buttress column to the guide rail of the hemispherical dome buttress column of the containment, thereby making it difficult to maintain stability and balance.

[0047] It is particularly important to note that in the following embodiments, the term "axial" means Figure 5 The axis P of the central suspension shaft 1 is in the direction shown and is parallel to the horizontal plane H. The term "transverse" means a direction parallel to the axial direction.

[0048] Ginseng Figure 1 As shown, the containment shell 200 is usually divided into two parts: a cylinder 210 and a hemispherical dome 220 . The cylinder 210 is perpendicular to the ground and forms a 90-degree angle with the horizontal plane. The buttresses 201 are arranged in the containment shell 200 and protrude from the shell wall of the containment shell 200 .

[0049] Please refer to Figures 1 to 16 A specific implementation of a containment construction system 100 is disclosed.

[0050] Ginseng Figure 1As shown, in this embodiment, the containment construction system 100 includes: a guide device 80 mounted on the outer facade 202 of the buttress 201, a lifting device 10 moving along the guide device 80, and a lifting platform 70 moving along the guide device 80 and spaced from the bottom of the lifting device 10. The guide device 80 is mounted on the outer facade 202 of the buttress 201 of the containment 200, and the lifting device 10 and the lifting platform 70 are mounted on the guide device 80, so that the lifting device 10 and the lifting platform 70 move along the outer facade 202 of the buttress 201 based on the path formed by the guide device 80, and then the operator performs operations on different positions of the buttress 201 of the containment 200 on the lifting platform 70.

[0051] Ginseng Figure 2 As shown, the guide device 80 includes two guide rails 81 arranged at intervals in the transverse direction. Figure 3 As shown, the guide rail 81a of the buttress column 201a of the cylinder 210 is perpendicular to the horizontal plane H, and the lifting device 10 and the lifting platform 70 move up and down along the guide rail 81a in the vertical plane. Figure 4 As shown, the guide rail 81b provided on the buttress 201b of the hemispherical dome 220 is arranged along the curved surface of the hemispherical dome 220, and the lifting device 10 and the lifting platform 70 perform lifting and lowering motions on the curved surface of the buttress 201b of the hemispherical dome 220 along the guide rail 81b.

[0052] The lifting device 10 includes: a suspension shaft 1, a power mechanism 2 disposed on both sides of the suspension shaft 1 and driving the suspension shaft 1 to rise and fall along the guide rail 81, a cantilever mechanism 4 disposed at both ends of the suspension shaft 1 to suspend a tensioning device (not shown), a pivot mechanism 6 rotatably connecting the power mechanism 2 and the suspension shaft 1, and a leveling mechanism 5 disposed on the power mechanism 2 to drive the suspension shaft 1 to rotate relative to the pivot mechanism 6. The suspension shaft 1 is parallel to the horizontal plane H, and the suspension shaft 1 is the core support of the lifting device 10, bearing the weight of other components such as the cantilever mechanism 4, and providing an installation foundation for other components (such as the power mechanism 2 and the cantilever mechanism 4). The power mechanism 2 provides power to drive the suspension shaft 1 and the cantilever mechanism 4 disposed at the end of the suspension shaft 1 and suspending the tensioning device to rise and fall along the guide rail 81 (hereinafter referred to as "the power mechanism 2 drives the suspension shaft 1 to rise and fall along the guide rail 81"). The cantilever mechanism 4 is configured with two groups and is respectively configured at the axial ends of the suspension shaft 1. The cantilever mechanism 4 is used to suspend the tensioning equipment (such as a jack) to drive the tensioning equipment to move to the working position. The power mechanism 2 is connected to the suspension shaft 1 through the pivot mechanism 6, so that the power mechanism 2 can drive the suspension shaft 1 to rise and fall along the guide rail 81 through the pivot mechanism 6. And it is convenient for the leveling mechanism 5 to drive the suspension shaft 1 to rotate along the axis P and relative to the pivot mechanism 6, and synchronously drive the cantilever mechanism 4 to rotate, so as to adjust the cantilever mechanism 4 and the tensioning equipment suspended by it to a horizontal posture parallel to the horizontal plane H.

[0053] Ginseng Figure 1 and Figure 2 and Figure 3 As shown, when the lifting device 10 is lifted and lowered along the guide rail 81a of the buttress column 201a of the cylinder 210, the power mechanism 2 and the suspension shaft 1 are connected by the pivot mechanism 6, so that the leveling mechanism 5 can drive the suspension shaft 1 to rotate along the axis P and synchronously drive the cantilever mechanism 4 to rotate until the cantilever mechanism 4 and the tensioning equipment suspended therefrom are adjusted to Figure 3 The horizontal posture parallel to the horizontal plane H shown in the figure, and the tensioning equipment is controlled by the leveling mechanism 5 to always maintain a horizontal posture during the working process, so that the power mechanism 2 drives the hanging weight shaft 1 to perform lifting movement along the guide rail 81a, thereby ensuring the construction accuracy of the tensioning equipment.

[0054] Ginseng Figure 1 and Figure 2 and Figure 4 As shown, when the lifting device 10 climbs to the guide rail 81b of the buttress column 201b of the hemispherical dome 220, the power mechanism 2 is connected to the suspension shaft 1 through the pivot mechanism 6, and the power mechanism 2 can be rotated through the pivot mechanism 6 and change its angle relative to the suspension shaft 1, so that the power mechanism 2 can adapt to the curvature change of the guide rail 81b, so that the power mechanism 2 can continue to provide power to the suspension shaft 1 along the guide rail 81b, avoiding the interruption of power transmission caused by the curvature change of the guide rail 81b, and then the power mechanism 2 drives the suspension shaft 1 to rise and fall stably along the guide rail 81b. At the same time, when the lifting device 10 climbs to the guide rail 81b, the cantilever mechanism 4 and the tensioning equipment suspended therefrom will tilt relative to the horizontal plane H and change to an inclined posture (this state is not shown), and the power mechanism 2 is connected to the suspension shaft 1 through the pivot mechanism 6, so that the leveling mechanism 5 can drive the suspension shaft 1 to rotate along the axis P, and synchronously drive the cantilever mechanism 4 to rotate, until the cantilever mechanism 4 and the tensioning equipment suspended therefrom are adjusted to the following state: Figure 4 The horizontal posture shown is parallel to the horizontal plane H, so that the cantilever mechanism 4 and the tensioning equipment suspended by it can adapt to the change of the curvature of the guide rail 81b, avoid the tensioning equipment from tilting relative to the horizontal plane H due to the change of the curvature of the guide rail 81b, and control the tensioning equipment to always maintain a horizontal posture during the operation through the leveling mechanism 5, thereby ensuring that the lifting device 10 can remain stable and balanced during the climbing process of the hemispherical dome 220, so as to ensure the construction accuracy of the tensioning equipment.

[0055] Preferably, the lifting device 10 includes two sets of power mechanisms 2, and the two sets of power mechanisms 2 are symmetrically arranged along the axis P of the suspension shaft 1. During the lifting process of the lifting device 10, the two symmetrically arranged sets of power mechanisms 2 work together to drive the suspension shaft 1 to perform lifting and lowering movements along the guide rail 81, and the load can be evenly shared, thereby improving the balance of the lifting device 10 and ensuring that the lifting device 10 rises or falls smoothly.

[0056] Ginseng Figure 2 and Fig.11 As shown, the lifting platform 70 includes: a load-bearing platform 71, a lifting mechanism 72 hinged to the load-bearing platform 71 to drive the load-bearing platform 71 to move up and down along the guide rail 81, and an adjusting mechanism 75 disposed on the lifting mechanism 72 and driving the load-bearing platform 71 to rotate relative to the lifting mechanism 72 through telescopic action. The load-bearing platform 71 is used for workers to stand and for construction equipment to be stored. The lifting mechanism 72 provides power to drive the load-bearing platform 71 to move up and down along the guide rail 81.

[0057] Ginseng Figure 1 and Figure 3 As shown, when the lifting platform 70 is lifted and lowered along the guide rail 81a of the buttress column 201a of the cylinder 210, the lifting mechanism 72 is hinged to the carrying platform 71, so that the adjustment mechanism 75 can drive the carrying platform 71 to rotate relative to the lifting mechanism 72 through telescopic action until the carrying platform 71 is adjusted to Figure 3 The horizontal posture parallel to the horizontal plane H shown in the figure, and the adjusting mechanism 75 is used to control the carrying platform 71 to always maintain a horizontal posture during the working process, so that the lifting mechanism 72 drives the carrying platform 71 to perform lifting and lowering movements along the guide rail 81a, thereby ensuring the horizontal accuracy of the carrying platform 71.

[0058] Ginseng Figure 1 and Figure 4 As shown in FIG. 1 , when the lifting platform 70 climbs to the guide rail 81b of the buttress column 201b of the hemispherical dome 220, the carrying platform 71 will tilt relative to the horizontal plane H and change to an inclined posture (this state is not shown), and the lifting mechanism 72 is hinged to the carrying platform 71, so that the adjustment mechanism 75 can drive the carrying platform 71 to rotate relative to the lifting mechanism 72 through a telescopic action until the carrying platform 71 is adjusted to the position as shown in FIG. Figure 4 The horizontal posture parallel to the horizontal plane H shown in the figure enables the bearing platform 71 to adapt to the change of the curvature of the guide rail 81b, avoiding the bearing platform 71 from tilting relative to the horizontal plane H due to the change of the curvature of the guide rail 81b, and controlling the bearing platform 71 to always maintain a horizontal posture during the operation through the adjustment mechanism 75, thereby ensuring that the lifting platform 70 can maintain stability and balance during the climbing process of the hemispherical dome 220, preventing the equipment from slipping or the operator from standing unstable due to the tilt of the bearing platform 71, thereby improving the safety of the operation.

The transmission shaft 22 passes through both ends of the mounting unit 61 and is rotatably connected to the mounting unit 61 to connect the power mechanism 2 with the suspension shaft 1, so that the power mechanism 2 can transmit power to the suspension shaft 1 to drive the suspension shaft 1 and the cantilever mechanism 4 carried by it to perform lifting and lowering movements along the guide rail 81. The mounting unit 61 is rotatably connected to the suspension shaft 1, so that the mounting unit 61 can support the suspension shaft 1 and the cantilever mechanism 4 to rotate smoothly. The telescopic rod 521 is driven to extend or shorten by the first telescopic unit 52 to drive the suspension shaft 1 to rotate along the axis P, so as to adjust the cantilever mechanism 4 and the tensioning equipment suspended by it to a horizontal posture, so that the lifting device 10 can adapt to complex construction environments and improve the adaptability and flexibility of the lifting device 10. The support assembly 51 is fixed to the connecting frame 21 to provide stable support for the first telescopic unit 52, ensure that the hinge point between the first telescopic unit 52 and the support assembly 51 is stable and reliable, and prevent the first telescopic unit 52 from loosening or deflecting during the process of driving the telescopic rod 521 to extend or shorten.

Figure 5 The shortened state shown in the figure is used to control the tensioning device to always maintain a horizontal posture during operation, so that the power mechanism 2 drives the suspension shaft 1 to move up and down along the guide rail 81a, thereby ensuring the construction accuracy of the tensioning device.

[0061] Ginseng Figure 1 , Figure 4 and Figure 5 As shown, when the lifting device 10 climbs to the guide rail 81b of the buttress column 201b of the hemispherical dome 220, the cantilever mechanism 4 and the tensioning equipment suspended therefrom will change to an inclined posture, and the suspension shaft 1 and the transmission shaft 22 are connected by rotating through the mounting unit 61, so that the first telescopic unit 52 drives the telescopic rod 521 to extend to drive the suspension shaft 1 to rotate along the axis P, and synchronously drives the cantilever mechanism 4 to rotate, until the cantilever mechanism 4 and the tensioning equipment suspended therefrom are adjusted to the following posture: Figure 4 The cantilever mechanism 4 and the tensioning device suspended therefrom can adapt to the curvature change of the guide rail 81b, thereby avoiding the tensioning device from tilting relative to the horizontal plane H due to the curvature change of the guide rail 81b. Then, the telescopic rod 521 is kept at Figure 4 The extended state shown in the figure is used to control the tensioning equipment to always maintain a horizontal posture during operation, thereby ensuring that the lifting device 10 can remain stable and balanced during the climbing process of the hemispherical dome 220, thereby ensuring the construction accuracy of the tensioning equipment.

The connection frame 21 serves as the main frame of the power mechanism 2, and is used to support and fix other components such as the transmission shaft 22 and the first drive motor 23. The transmission shaft 22 is driven by the first driving motor 23 to rotate relative to the connecting frame 21, and the transmission shaft 22 synchronously drives the power gears 24 at both ends to rotate. The power gears 24 at both ends of the transmission shaft 22 are respectively engaged with the racks formed on the outer side of the guide rail 81, so that the power gears 24 move along the racks, so as to drive the suspension shaft 1 to move up and down along the guide rail 81.

The positioning sleeve 53 is used to ensure a stable connection between the telescopic rod 521 of the first telescopic unit 52 and the suspension shaft 1. The first telescopic unit 52 drives the telescopic rod 521 to extend or shorten to drive the positioning sleeve 53 to synchronously drive the suspension shaft 1 to rotate along the axis P. In addition, when the first telescopic unit 52 drives the telescopic rod 521 to extend or shorten, the driving force F1 generated is transmitted to the suspension shaft 1 through the positioning sleeve 53, and the driving force F1 is evenly distributed to the suspension shaft 1 and the cantilever mechanism 4 configured thereto through the positioning sleeve 53, so as to improve the leveling accuracy and ensure that the cantilever mechanism 4 and the horizontal posture of the tensioning equipment suspended therefrom are more stable. The fixed end of the first telescopic unit 52 is hinged to the support seat 512, and the support seat 512 serves as a connecting piece between the support arm 511 and the first cross bar 211, so that the support seat 512 can provide stable support for the first telescopic unit 52 driving the telescopic rod 521 to extend or retract, so as to prevent the first telescopic unit 52 from shaking or deflecting due to unstable support during the extension and retraction process, thereby ensuring the accuracy and stability of the leveling of the suspension shaft 1.

[0064] The support arm 511 is arranged on the connection frame 212 and connected to the connection frame 212 by bolts to stably support the first telescopic unit 52. The connection frame 212 makes the support arm 511 and the first cross bar 211 stably connected, and ensures that the relative position between the support arm 511 and the first cross bar 211 is fixed, so as to enhance the structural stability of the entire leveling mechanism 5. The reaction force F2 generated during the telescopic rod 521 driven by the first telescopic unit 52 can be evenly dispersed to the support arm 511 and the first cross bar 211 through the support seat 512, so as to avoid excessive force on a single support component (such as the support arm 511 or the first cross bar 211) causing structural deformation or damage, thereby ensuring the structural integrity of the lifting device 10. The support structure composed of the first cross bar 211, the connection frame 212, the support arm 511 and the support seat 512 can provide stable support for the first telescopic unit 52 during the leveling process and evenly disperse the reaction force F2, thereby ensuring the accuracy and reliability of the suspended weight axis 1 during the leveling process. Furthermore, the support seat 512 is formed outside the transmission shaft 22 and does not contact the transmission shaft 22 , thereby preventing the reaction force F2 from acting directly or indirectly on the transmission shaft 22 , and preventing local force on the transmission shaft 22 from causing structural deformation or damage.

[0065] Ginseng Figure 5 and Figure 7As shown, the cantilever mechanism 4 includes: a first rotating cantilever 41 rotating in a first horizontal plane H1, a second rotating cantilever 43 arranged on the first rotating cantilever 41 and rotating in a second horizontal plane H2, and a suspension device 45 arranged on the second rotating cantilever 43 and suspending the tensioning device. The first rotating cantilever 41 rotates in the first horizontal plane H1 and supports the second rotating cantilever 43 to rotate in the second horizontal plane H2, so as to drive the suspension device 45 to suspend the tensioning device and move it to a desired position, so that the cantilever mechanism 4 can cover a larger working area.

[0066] Ginseng Figure 7 As shown, the first rotating cantilever 41 includes: a first mounting seat 411 and a first cantilever 42, a first slewing bearing 412 clamped between the first mounting seat 411 and the first cantilever 42, the first cantilever 42 rotates relative to the first mounting seat 411 in the first horizontal plane H1 through the first slewing bearing 412, a first slewing gear 413 coaxially sleeved on the outer periphery of the first slewing bearing 412, at least two second driving motors 414 arranged at equal intervals on the first mounting seat 411, and a first driving gear 415 arranged on the output shaft of the second driving motor 414 and meshing with the first slewing gear 413. The first cantilever 42 and the second cantilever 44 are located on two different parallel planes, and the first horizontal plane H1 and the second horizontal plane H2 are parallel to each other to ensure the overall leveling accuracy of the cantilever mechanism 4. The second driving motor 414 drives the first rotating gear 413 to rotate through the first driving gear 415 on its output shaft. The first rotating gear 413 drives the first cantilever 42 to rotate in the first horizontal plane H1 through the first rotating bearing 412 to adjust the position of the second rotating cantilever 43 and the suspension device 45, so that the suspension device 45 suspends the tensioning device and moves it to the desired position, so that the tensioning device can cover a larger working area and increase the operating range of the cantilever mechanism 4.

[0067] At least two second drive motors 414 are arranged at equal intervals on the first mounting seat 411, and the output shaft of each second drive motor 414 is provided with a first driving gear 415, and the first driving gear 415 is meshed with the first rotating gear 413. By driving the first rotating gear 413 to rotate by at least two second drive motors 414, the load can be evenly distributed to the plurality of second drive motors 414, so as to avoid concentrating the load on a single second drive motor 414, and the rotational driving force of the plurality of second drive motors 414 is transmitted to the first rotating gear 413 more evenly, so as to reduce the unilateral wear of the first rotating gear 413 and extend the service life of the first rotating gear 413. Moreover, by at least two second drive motors 414, even if one of the second drive motors 414 fails, the other second drive motors 414 can still continue to work, so as to ensure the function of the cantilever mechanism 4 to control the rotation of the first rotating cantilever 41, and improve the reliability and safety of the lifting device 10.

[0068] Preferably, the first rotating cantilever 41 includes two second drive motors 414, and the two second drive motors 414 are symmetrically arranged on the first mounting seat 411. The two second drive motors 414 are symmetrically arranged on the first mounting seat 411, so that the load can be evenly distributed on the two second drive motors 414. Since the load is evenly distributed, the load borne by a single second drive motor 414 is significantly reduced, and the local stress concentration of related components such as the first driving gear 415 and the first rotating gear 413 is reduced, and the service life of related components such as the first driving gear 415 and the first rotating gear 413 is extended. By the two second drive motors 414 working at the same time to provide a more uniform rotational driving force output, it is possible to reduce the vibration of related components such as the first rotating gear 413 during the rotation process, so that the rotation of the first cantilever 42 is more stable, and the rotation accuracy of the first cantilever 42 is improved.

[0069] Ginseng Figure 7 As shown, the second rotating cantilever 43 includes: a second cantilever 44 equipped with a suspension device 45, a second mounting seat 431 arranged on the first cantilever 42, a second slewing bearing 432 clamped between the second mounting seat 431 and the second cantilever 44, the second cantilever 44 rotates relative to the second mounting seat 431 in the second horizontal plane H2 through the second slewing bearing 432, a second slewing gear 433 coaxially sleeved on the outer periphery of the second slewing bearing 432, at least two third driving motors 434 arranged at equal intervals on the second mounting seat 431, and a second driving gear 435 arranged on the output shaft of the third driving motor 434 and meshing with the second slewing gear 433; the suspension device 45 suspends the tensioning device and moves along the length direction of the second cantilever 44. The third driving motor 434 drives the second rotating gear 433 to rotate through the second driving gear 435 on its output shaft. The second rotating gear 433 drives the second cantilever 44 to rotate in the second horizontal plane H2 through the second rotating bearing 432 to adjust the position of the suspension device 45, so that the suspension device 45 can suspend the tensioning device and move it to the desired position along the length direction of the second cantilever 44, so that the tensioning device can cover a larger working area and increase the operating range of the cantilever mechanism 4.

[0070] By arranging at least two third drive motors 434 at equal intervals to drive the second rotating gear 433 to rotate, the load can be evenly distributed to the plurality of third drive motors 434, thereby avoiding the load being concentrated on a single third drive motor 434, and making the rotational driving force of the plurality of third drive motors 434 be transmitted to the second rotating gear 433 more evenly, so as to reduce the unilateral wear of the second rotating gear 433 and extend the service life of the second rotating gear 433. In addition, by arranging at least two third drive motors 434 at equal intervals, even if one of the third drive motors 434 fails, the other third drive motors 434 can still continue to work, thereby ensuring the function of the lifting device 10 to control the rotation of the second cantilever 44, and improving the reliability and safety of the lifting device 10.

[0071] Preferably, the second rotating cantilever 43 includes two third drive motors 434, and the two third drive motors 434 are symmetrically arranged on the second mounting seat 431. The load can be evenly distributed on the two third drive motors 434. Since the load is evenly distributed, the load borne by a single third drive motor 434 is significantly reduced, and the local stress concentration of related components such as the second driving gear 435 and the second rotating gear 433 is reduced, thereby extending the service life of related components such as the second driving gear 435 and the second rotating gear 433. By the two third drive motors 434 working at the same time, a more uniform rotational driving force output is provided, thereby reducing the vibration of related components such as the second rotating gear 433 during rotation, making the rotation of the second cantilever 44 more stable, and improving the rotation accuracy of the second cantilever 44.

[0072] Ginseng Figure 7 As shown, the lifting device 10 further includes: a reinforcing hoop 8 which is arranged on the outer periphery of the suspension shaft 1 and connected to the first mounting seat 411. The reinforcing hoop 8 is connected to the first mounting seat 411 by bolts to ensure that the cantilever mechanism 4 is firmly connected to the suspension shaft 1.

[0073] In this embodiment, the longitudinal section of the first cantilever 42 may be square, and a rib plate (not shown) is disposed on the outer side of the bottom of the first cantilever 42 to increase the rigidity and torsion resistance of the square tube, and the longitudinal section of the second cantilever 44 may be an "I" shape. It should be noted that the aforementioned square longitudinal section shape of the first cantilever 42 and its matching mode with the rib plate and the "I" longitudinal section shape of the second cantilever 44 are only a typical example, and the longitudinal section shapes of the first cantilever 42 and the second cantilever 44 may also include other high-strength, bending and torsion-resistant shapes. For example, a rib plate may be provided inside and / or outside the first cantilever 42 to comprehensively improve the rigidity and torsion resistance of the first cantilever 42, so that the first cantilever 42 can carry a large weight; for example, the second cantilever 44 may be configured as a box beam structure formed by welding two I-beams and allowing the suspension device 45 to move along its length direction, so as to improve the bending and torsion rigidity of the second cantilever 44, so that the second cantilever 44 can carry a large weight.

[0074] Ginseng Figure 2 and Figure 5 As shown, the lifting device 10 also includes: a first anti-fall mechanism 3a configured on the power mechanism 2 to prevent the power mechanism 2 from moving along the guide rail 81; the first anti-fall mechanism 3a is configured on the power mechanism 2, and is used to prevent the lifting device 10 from falling out of control in an emergency situation (such as stalling, falling), thereby ensuring the safety of the operating personnel and the device.

[0075] Ginseng Figure 5 and Figure 8 and Fig. 9As shown, the first anti-fall mechanism 3a includes: a housing 31 disposed on the connecting frame 21 and penetrated by the transmission shaft 22, an anti-fall device 32 disposed on the housing 31, and a transmission assembly disposed in the housing 31 and connected to the anti-fall device 32 to limit the rotation of the transmission shaft 22. When an emergency occurs in the lifting device 10, the anti-fall device 32 quickly locks the transmission assembly (not shown) to prevent the transmission shaft 22 from rotating, and at the same time prevents the power gears 24 at both ends of the transmission shaft 22 from continuing to move along the rack, so as to prevent the lifting device 10 from falling out of control. The transmission assembly includes: a transmission gear 33 coaxially sleeved on the transmission shaft 22, and a speed-increasing gear 35 disposed in the housing 31 and rotatably connected to the housing 31; the anti-fall device 32 is constructed with a brake gear 34 meshing with the transmission gear 33. The speed-increasing gear 35 is formed between the transmission gear 33 and the brake gear 34 and meshes with the transmission gear 33 and the brake gear 34. Under normal working conditions, the first drive motor 23 drives the transmission shaft 22 to drive the power gear 24 to move along the rack, so as to drive the suspension shaft 1 to move up and down, and the transmission shaft 22 synchronously drives the transmission gear 33 to rotate, so that the transmission gear 33 drives the speed-increasing gear 35 to drive the brake gear 34 to rotate. When an emergency occurs in the lifting device 10, the transmission gear 33 drives the speed-increasing gear 35 to drive the brake gear 34 to rotate rapidly, and the anti-fall device 32 is activated when detecting the emergency situation, and the anti-fall device 32 quickly locks the brake gear 34. Since the brake gear 34 is meshed with the speed-increasing gear 35, the speed-increasing gear 35 is limited to rotate through the brake gear 34, thereby preventing the transmission gear 33 and the transmission shaft 22 from rotating, and at the same time preventing the power gears 24 at both ends of the transmission shaft 22 from continuing to move along the guide rail 81, so as to achieve simultaneous locking of both sides of the transmission shaft 22 during emergency braking, and prevent the lifting device 10 from falling out of control.

[0076] The speed increasing gear 35 can ensure the synchronous meshing between the transmission gear 33 and the brake gear 34, avoid slipping or incomplete meshing between the transmission gear 33 and the brake gear 34 during emergency braking, make the emergency braking process smoother, and reduce the impact during emergency braking. In addition, the speed increasing gear 35 can increase the rotation speed of the brake gear 34 relative to the transmission gear 33, thereby accelerating the response speed of the anti-fall device 32 to detect the stall of the transmission shaft 22, so as to quickly lock the brake gear 34 to prevent the transmission shaft 22 from rotating, further reduce the uncontrolled falling distance of the lifting device 10, and make the emergency braking more rapid and effective.

[0077] In this embodiment, preferably, the first anti-falling mechanism 3a is arranged at the power mechanism 2 at the bottom of the suspension shaft 1, and the transmission gear 33 is sleeved on the outside of the transmission shaft 22 at the bottom of the connecting frame 21. By arranging the first anti-falling mechanism 3a at the power mechanism 2 at the bottom of the suspension shaft 1, the braking mechanism can be quickly triggered and the braking gear 34 can be locked in an emergency to prevent the transmission shaft 22 from rotating, thereby reducing the uncontrolled falling distance of the lifting device 10. In addition, the available space of the lifting device 10 can be fully utilized to avoid increasing the overall volume and maintain the compactness of the device.

[0078] Ginseng Figure 5 As shown, the mounting unit 61 is arranged on the side of the suspension shaft 1 close to the cantilever mechanism 4. At least one mounting unit 61 is respectively arranged on the two sides of the suspension shaft 1 close to the cantilever mechanism 4. By configuring the mounting unit 61 on the side of the suspension shaft 1 close to the cantilever mechanism 4, the mounting unit 61 forms a support point on the side of the suspension shaft 1 close to the cantilever mechanism 4 to disperse the load at the end of the suspension shaft 1 and reduce the stress concentration at the end of the suspension shaft 1, thereby reducing the bending deformation of the suspension shaft 1 caused by the concentrated load. In addition, the mounting unit 61 as a support point can also enhance the rigidity of the suspension shaft 1, making the suspension shaft 1 more stable when bearing the load, thereby reducing the horizontal posture deviation of the cantilever mechanism 4 caused by bending deformation, so as to improve the accuracy of the lifting device 10 when adjusting the horizontal posture of the cantilever mechanism 4, and ensure that the cantilever mechanism 4 and the suspended tensioning equipment maintain a more stable horizontal posture during the working process.

[0079] Specifically, refer to Fig.10 As shown, the mount unit 61 includes: a first sleeve portion 611 coaxially sleeved on the outside of the suspension shaft 1 and rotatably connected to the suspension shaft 1, a plurality of mount plates 612 fixedly mounted on the first sleeve portion 611, the two ends of the mount plate 612 in the length direction are penetrated by the transmission shaft 22 close to the two sides of the suspension shaft 1, and a second sleeve portion 613 radially clamped between the end of the mount plate 612 and the transmission shaft 22. The first sleeve portion 611 is used to ensure that the suspension shaft 1 can rotate freely relative to the mount unit 61. The transmission shaft 22 is connected to the first sleeve portion 611 through the mount plate 612, which plays the role of transmitting driving force and providing support, and the number of the mount plates 612 can be adjusted according to actual needs to ensure sufficient support strength. The second sleeve portion 613 is radially clamped between the end of the mount plate 612 and the transmission shaft 22 to ensure a firm connection between the mount plate 612 and the transmission shaft 22, and to ensure that the transmission shaft 22 can rotate freely relative to the mount unit 61.

[0080] Ginseng Fig.10As shown, at least two mounting units 61 are respectively arranged on both sides of the suspension shaft 1 close to the cantilever mechanism 4. The mounting unit 61a is arranged at the end of the transmission shaft 22 extending out of the connection frame 212 and forming a support point on the suspension shaft 1, and the mounting unit 61b is arranged at the shaft section of the transmission shaft 22 that does not penetrate the connection frame 212. The mounting unit 61a is closer to the position of the load-bearing tensioning device to further reduce the bending stress at the end of the suspension shaft 1 and improve the rigidity and stability of the suspension shaft 1. Although the mounting unit 61b is farther away from the end of the suspension shaft 1 than the mounting unit 61a, it can provide an additional support point, which helps to disperse the load on the suspension shaft 1, thereby reducing the stress concentration on a single support point and reducing the deformation caused by excessive force on a single point. Through the joint support of the mounting unit 61a and the mounting unit 61b, the rigidity of the suspension shaft 1 is improved, making the suspension shaft 1 more stable.

[0081] It should be noted that the first sleeve portion 611 and the second sleeve portion 613 are respectively rotatably connected to the suspension shaft 1 and the transmission shaft 22 through bearings (for example, graphite copper sleeves, rolling bearings, etc. that can achieve rotation function) to ensure that the mount unit 61 and the suspension shaft 1 and the transmission shaft 22 rotate smoothly.

[0082] Ginseng Fig.11 and Fig.12 As shown, the lifting mechanism 72 includes: a connecting frame 721 hinged to the side of the bottom of the carrying platform 71 close to the guide rail 81; the adjusting mechanism 75 includes: a third telescopic unit 751 configured on the connecting frame 721, a fixed end 7511 of the third telescopic unit 751 is hinged to the side of the connecting frame 721 away from the carrying platform 71, and a telescopic rod 7512 of the third telescopic unit 751 is hinged to the side of the carrying platform 71 opposite to the guide rail 81. By hingedly connecting the connecting frame 721 to the side of the bottom of the carrying platform 71 close to the guide rail 81, the connection point between the connecting frame 721 and the carrying platform 71 is close to the guide rail 81, which helps the lifting mechanism 72 to transmit power to the carrying platform 71 more directly, thereby reducing energy loss and improving lifting efficiency. By hingedly connecting the fixed end 7511 of the third telescopic unit 751 to the side of the connecting frame 721 away from the carrying platform 71, the connecting frame 721 provides a support position away from the carrying platform 71 for the fixed end 7511 of the third telescopic unit 751, which helps the third telescopic unit 751 to more effectively transmit the telescopic torque to the carrying platform 71, ensuring that the adjustment mechanism 75 can accurately control the horizontal posture of the carrying platform 71. By hingedly connecting the telescopic rod 7512 of the third telescopic unit 751 to the side of the carrying platform 71 opposite to the guide rail 81, the carrying platform 71 provides a hinged position opposite to the guide rail 81 for the telescopic rod 7512 of the third telescopic unit 751, which helps the third telescopic unit 751 to more effectively transmit the telescopic torque to the carrying platform 71, ensuring that the carrying platform 71 always maintains a horizontal posture at different positions.

[0083] Ginseng Figure 1 , Figure 3 and Fig.11 As shown, when the lifting platform 70 is lifted and lowered along the guide rail 81a of the buttress column 201a of the cylinder 210, the third telescopic unit 751 is hinged to the bottom of the carrying platform 71 through the connecting frame 721, and the telescopic rod 7512 is extended to drive the carrying platform 71 to rotate relative to the connecting frame 721 until the carrying platform 71 is adjusted to Figure 3 The telescopic rod 7512 is then held in the horizontal position by the third telescopic unit 751. Figure 3 The extended state shown in the figure is used to control the carrying platform 71 to always maintain a horizontal posture during the working process, so that the lifting mechanism 72 ensures the horizontal accuracy of the carrying platform 71 when driving the carrying platform 71 to move up and down along the guide rail 81a.

[0084] Ginseng Figure 1 and Figure 4 As shown, when the lifting platform 70 climbs to the guide rail 81b of the buttress column 201b of the hemispherical dome 220, the carrying platform 71 will tilt relative to the horizontal plane H and change to an inclined posture (this state is not shown), and the third telescopic unit 751 is hinged to the bottom of the carrying platform 71 through the connecting frame 721, and the telescopic rod 7512 is shortened to drive the carrying platform 71 to rotate relative to the connecting frame 721, so as to adjust the carrying platform 71 to the following state: Figure 4 The horizontal posture parallel to the horizontal plane H is shown, so that the carrying platform 71 can adapt to the curvature change of the guide rail 81b, and avoid the carrying platform 71 being tilted relative to the horizontal plane H due to the curvature change of the guide rail 81b. Then, the telescopic rod 7512 is kept at Figure 4 The shortened state shown in the figure is used to control the carrying platform 71 to always maintain a horizontal posture during the operation, thereby ensuring that the lifting platform 70 remains stable and balanced during the climbing process, ensuring the horizontal accuracy of the carrying platform 71, preventing the equipment from slipping or the operator from standing unstable due to the tilt of the carrying platform 71, and improving operational safety and work efficiency.

[0085] Ginseng Fig.11 and Fig.12As shown, the connection frame 721 includes: a second crossbar 7211, a connection frame 7212 disposed at both ends of the second crossbar 7211 in the length direction; the lifting mechanism 72 also includes: a rotating shaft 722 disposed at both sides of the second crossbar 7211 and penetrating the connection frame 7212 and rotatably connected to the connection frame 7212, a fourth driving motor 723 disposed at the second crossbar 7211 to drive the rotating shaft 722 to rotate, a driving gear 724 coaxially sleeved at both ends of the rotating shaft 722 and meshing with the rack formed on the outer side of the guide rail 81, and a plurality of guide wheels 725 symmetrically disposed on the inner side wall of the connection frame 7212 and rotatably connected to the connection frame 7212, and the guide wheels 725 are formed in the guide grooves formed on both sides of the guide rail 81. The connection frame 721 is the main frame of the lifting mechanism 72, and is used to support and fix the rotating shaft 722, the fourth driving motor 723 and other components. Preferably, the lifting mechanism 72 includes two rotating shafts 722, and the two rotating shafts 722 are symmetrically arranged on the upper and lower sides of the connecting frame 721. The rotating shaft 722 is driven by the fourth driving motor 723 to rotate relative to the connecting frame 721, and the rotating shaft 722 synchronously drives the driving gears 724 at both ends to rotate. The driving gears 724 at both ends of the rotating shaft 722 are respectively engaged with the racks formed on the outer side of the guide rail 81, so that the driving gears 724 move along the racks, so as to drive the bearing platform 71 to move up and down along the guide rail 81. The guide wheels 725 are respectively located in the guide grooves formed on both sides of the guide rail 81, and synchronously drive the guide wheels 725 to move along the guide grooves when the lifting platform 70 is lifted or lowered. The guide wheels 725 are rotatably connected to the connecting frame 7212 through self-lubricating bearings, so that the guide wheels 725 can smoothly run up and down along the guide rail 81. And through the symmetrically arranged guide wheels 725, it can be ensured that the lifting platform 70 remains stable during the lifting process, and the shaking and deviation are reduced.

[0086] Ginseng Fig.11 and Fig.12 As shown, the connection frame 7212 extends toward the bearing platform 71 to form an extension hinge 72123, and a first hinge seat 711 hinged to the extension hinge 72123 is constructed on the side of the bottom of the bearing platform 71 close to the guide rail 81; the end of the connection frame 7212 away from the extension hinge 72123 extends along the side opposite to the guide rail 81 to form a support hinge 72124, and the support hinge 72124 is hinged to the fixed end 7511 of the third telescopic unit 751; the side of the bearing platform 71 opposite to the guide rail 81 is constructed to form a second hinge seat 712 hinged to the telescopic rod 7512 of the third telescopic unit 751. The extension hinge 72123 is hinged to the first hinge seat 711 to form as shown. Fig.12The axis L is shown in FIG. By extending the hinge 72123 and hingedly connecting the first hinge seat 711, the connection point between the connecting frame 7212 and the carrying platform 71 is close to the guide rail 81, which helps the lifting mechanism 72 to transmit power to the carrying platform 71 more directly, so as to reduce energy loss and improve lifting efficiency. It is also ensured that the connection between the connecting frame 7212 and the carrying platform 71 is stable and reliable, so that the carrying platform 71 can change its angle relative to the guide rail 81 to adapt to the curvature change of the guide rail 81, and ensure that the carrying platform 71 remains stable and balanced during the climbing process. By hingedly connecting the fixed end 7511 of the third telescopic unit 751 to the support hinge 72124, the connecting frame 7212 provides a support position away from the carrying platform 71 for the fixed end 7511 of the third telescopic unit 751, which helps the third telescopic unit 751 to more effectively transmit the telescopic torque to the carrying platform 71, and ensures that the adjustment mechanism 75 can accurately control the horizontal posture of the carrying platform 71. And ensure that the connection between the fixed end 7511 of the third telescopic unit 751 and the connecting frame 7212 is stable and reliable, so as to prevent the third telescopic unit 751 from loosening or shifting during the telescopic process of driving the telescopic rod 7512 to be extended or extended. By hingedly connecting the telescopic rod 7512 of the third telescopic unit 751 to the second hinge seat 712, the support platform 71 provides the support platform 71 with a hinge position opposite to the guide rail 81, which helps the third telescopic unit 751 to more effectively transmit the telescopic torque to the support platform 71, and ensure that the support platform 71 always maintains a horizontal posture at different positions. The third telescopic unit 751 drives the telescopic rod 7512 to extend or shorten, so as to drive the support platform 71 to rotate along the axis L and relative to the connecting frame 7212 through the second hinge seat 712, so as to adjust the inclination angle of the support platform 71 relative to the horizontal plane H.

[0087] It should be noted that, in the present embodiment, the first telescopic unit 52 and the third telescopic unit 751 can be configured as telescopic devices such as hydraulic cylinders, electric push rods, pneumatic cylinders or electric screws. As long as the first telescopic unit 52 can drive the suspension shaft 1 to rotate along its axis P through a telescopic action to adjust the inclination angle of the cantilever mechanism 4 and its suspended tensioning device relative to the horizontal plane H and adjust the cantilever mechanism 4 and its suspended tensioning device to a horizontal posture, it can be either of the above. As long as the third telescopic unit 751 can drive the load-bearing platform 71 through a telescopic action to rotate the load-bearing platform 71 relative to the connecting frame 721 and adjust the load-bearing platform 71 to a horizontal posture, it can be either of the above.

[0088] Ginseng Fig.11 As shown, the lifting platform 70 also includes: a second anti-falling mechanism 3b configured on the lifting mechanism 72 to prevent the lifting mechanism 72 from moving along the guide rail 81; the second anti-falling mechanism 3b is configured on the lifting mechanism 72, and is used to prevent the lifting platform 70 from falling out of control in an emergency situation (such as stalling, falling), thereby ensuring the safety of operators and equipment.

[0089] Ginseng Figure 8 and Fig. 9 As shown, the second anti-falling mechanism 3b includes: a housing 31 disposed on the connecting frame 721 and penetrated by the rotating shaft 722, an anti-falling device 32 disposed on the housing 31, and a transmission assembly disposed in the housing 31 and connected to the anti-falling device 32 to limit the rotation of the rotating shaft 722. When an emergency occurs in the lifting platform 70, the anti-falling device 32 quickly locks the transmission assembly (not shown) to prevent the rotating shaft 722 from rotating, and at the same time prevents the driving gears 724 at both ends of the rotating shaft 722 from continuing to move along the rack, so as to prevent the lifting platform 70 from falling out of control.

[0090] Ginseng Figure 8 and Fig. 9 As shown, the transmission assembly includes: a transmission gear 33 coaxially sleeved on the rotating shaft 722, and a speed increasing gear 35 internally arranged in the housing 31 and rotatably connected to the housing 31; the anti-fall device 32 is constructed with a brake gear 34 meshing with the transmission gear 33. The speed increasing gear 35 is formed between the transmission gear 33 and the brake gear 34 and meshes with the transmission gear 33 and the brake gear 34. Under normal working conditions, the fourth driving motor 723 drives the rotating shaft 722 to drive the driving gear 724 to move along the rack to drive the carrying platform 71 to move up and down, and the rotating shaft 722 synchronously drives the transmission gear 33 to rotate, so that the transmission gear 33 drives the speed increasing gear 35 to drive the brake gear 34 to rotate. When an emergency occurs on the lifting platform 70, the transmission gear 33 drives the speed increasing gear 35 to drive the brake gear 34 to rotate rapidly. The anti-fall device 32 is activated when detecting the emergency situation. The anti-fall device 32 quickly locks the brake gear 34. Since the brake gear 34 is meshed with the speed increasing gear 35, the speed increasing gear 35 is limited to rotate through the brake gear 34, thereby preventing the transmission gear 33 and the rotating shaft 722 from rotating, and at the same time preventing the driving gears 724 at both ends of the rotating shaft 722 from continuing to move along the guide rail 81, so as to achieve simultaneous locking of both sides of the rotating shaft 722 during emergency braking, and prevent the lifting platform 70 from falling out of control. The speed increasing gear 35 can ensure synchronous meshing between the transmission gear 33 and the brake gear 34, avoid slipping or incomplete meshing between the transmission gear 33 and the brake gear 34 during emergency braking, and make the emergency braking process smoother, which can reduce the impact during emergency braking. In addition, the speed-increasing gear 35 can be used to increase the rotation speed of the brake gear 34 relative to the transmission gear 33, thereby accelerating the response speed of the fall arrester 32 in detecting the stall of the rotating shaft 722, so as to quickly lock the brake gear 34 to prevent the rotating shaft 722 from rotating, further reducing the uncontrolled falling distance of the lifting platform 70, and making emergency braking more rapid and effective.

[0091] Preferably, two groups of speed increasing gears 35 are symmetrically arranged on both sides of the brake gear 34. When the anti-fall mechanism (i.e., the first anti-fall mechanism 3a and the second anti-fall mechanism 3b) is started, it can ensure that the braking effect on both sides of the transmission gear 33 is uniform during emergency braking, thereby improving the stability during emergency braking.

[0092] It should be noted that the first anti-fall mechanism 3a and the second anti-fall mechanism 3b in the present embodiment have the same structure. The specific structure of the anti-fall device 32 included in the first anti-fall mechanism 3a and the second anti-fall mechanism 3b is the existing technology, which can be a mechanical, electromagnetic or other type of braking device, which will not be elaborated here. As long as it can quickly lock the sensing shaft 321 to prevent the brake gear 34 from rotating when an emergency is detected, it can be used.

[0093] Ginseng Fig.11 and Fig.12 As shown, the lifting platform 70 further includes: a flip guardrail 76 hinged to the carrying platform 71, and a winch 77 configured on the carrying platform 71 for retracting and releasing the flip guardrail 76. The bottom of the flip guardrail 76 is hinged to the carrying platform 71, and is hinged with the carrying platform 71 to form a Fig.12 The winch 77 is controlled to rotate the rollover guardrail 76 around the axis K in the direction indicated by K1, so that the rollover guardrail 76 is overlapped to the surface of the containment shell to eliminate the gap between the containment shell and the carrying platform 71, prevent people or objects from falling, and improve the safety of the operation.

[0094] Ginseng Fig.11 and Fig.12As shown, the lifting platform 70 also includes: an auxiliary platform 78 arranged on both sides of the carrying platform 71, a second telescopic unit 781 hinged to the bottom of the auxiliary platform 78, a bottom plate 782 controlled by the second telescopic unit 781 to extend or retract to the bottom of the auxiliary platform 78, a fourth telescopic unit 783 arranged at the bottom of the auxiliary platform 78, a universal ball head (not shown) arranged at the end of the telescopic shaft (not marked) of the fourth telescopic unit 783, a universal seat (not marked) movably connected to the universal ball head, and a support plate 786 arranged on the universal seat. The second telescopic unit 781 is hinged to the auxiliary platform 78, and the telescopic shaft of the second telescopic unit 781 is hinged to the bottom plate 782. When the carrying platform 71 reaches the specified position, the support plate 786 is driven to abut against the surface of the containment by extending the telescopic shaft of the fourth telescopic unit 783 to fix the position of the carrying platform 71, prevent the carrying platform 71 from shaking back and forth during operation, and improve the overall stability. Since the surface of the containment shell may be inclined, the support plate 786 can be adjusted according to the inclination angle of the containment shell surface through the universal ball head and the universal seat, ensuring that the support plate 786 can fully fit the surface of the containment shell and improve stability. By configuring the auxiliary platform 78 on both sides of the bearing platform 71, the working space and the carrying work equipment can be expanded to provide more operating areas for operators. The second telescopic unit 781 is hinged to the auxiliary platform 78, and its telescopic axis is hinged to the bottom plate 782, so that the bottom plate 782 can be extended or retracted to the bottom of the auxiliary platform 78. By driving the bottom plate 782 to extend and abut against the side of the buttress column by the second telescopic unit 781, the range of the auxiliary platform 78 can be expanded to increase the working area.

[0095] It should be noted that the second telescopic unit 781 and the fourth telescopic unit 783 can be configured as telescopic devices such as hydraulic cylinders, electric push rods, pneumatic cylinders or electric screws, as long as the second telescopic unit 781 can drive the base plate 782 to extend and abut against the side of the buttress column 201 through a telescopic action, and as long as the fourth telescopic unit 783 can drive the support plate 786 to extend and abut against the surface of the containment shell through a telescopic action.

[0096] Ginseng Fig.11 As shown, the lifting platform 70 also includes a protective cover 79 fixed to the bearing platform 71 and formed on the outside of the guide rail 81. The protective cover 79 covers the outside of the guide rail 81, isolating the guide rail 81 from the working area to prevent workers from accidentally touching the guide rail 81 and reducing the risk of injury caused by accidental contact. It can also prevent foreign objects (such as tools, parts, etc.) from falling onto the guide rail 81 and prevent foreign objects from getting stuck between the rack and the drive gear 724, causing equipment damage or operation failure.

[0097] Ginseng Fig.13 and Fig.14As shown, the guide device 80 also includes: an embedded part 82 disposed on the back side of the guide rail 81 and embedded in the buttress column 201, a cushion block 83 disposed between the embedded part 82 and the guide rail 81, and an outer pressure plate 84 disposed on the side of the guide rail 81 facing away from the cushion block 83. The side of the guide rail 81 extends outward laterally to form a fixed portion (i.e., the first fixed portion 811 and / or the second fixed portion 812 described below) clamped by the cushion block 83 and the outer pressure plate 84, and a locking member (not shown) continuously penetrates the outer pressure plate 84, the cushion block 83 and the embedded part 82 to fix the guide rail 81 to the outer facade 202 of the buttress column 201, and the cushion block 83 is disposed on the back side of the guide rail 81, and the thickness of the cushion block 83 is adjusted so that the meshing surface of the rack formed on the outside of the guide rail 81 and the gears (i.e., the driving gear 724 and the power gear 24) included in the lifting mechanism 72 and the power mechanism 2 are meshed on the same reference plane.

[0098] It should be noted that the back side of each single guide rail 81 is provided with an embedded part 82 embedded in the buttress column 201 to fix the single guide rail 81 respectively. The embedded parts 82 respectively provided on the back sides of the two guide rails 81 can be an integral structure (that is, one embedded part 82 extends to the back sides of the two guide rails 81 along the setting direction of the two guide rails 81), or a split structure (that is, one embedded part 82 is independently provided on the back sides of the two guide rails 81). In the following description, only one embedded part 82 is provided on the back sides of the two guide rails 81 for exemplary description. The embedded part 82 is embedded in the buttress column 201 and forms an installation surface (not marked) exposed to the facade 202 for installing the pad 83. The outer pressure plate 84, the pad 83 and the embedded part 82 are continuously penetrated by a locking part (for example, a bolt) to fix the pad 83 and the outer pressure plate 84 through the embedded part 82. At the same time, when fixing the cushion block 83 and the outer pressure plate 84, the cushion block 83 and the outer pressure plate 84 jointly clamp the fixing part to play the role of fixing the guide rail 81, so that the installation of the guide rail 81 is more firmly ensured, so as to further ensure the stability of the guide rail 81, and prevent the guide rail 81 from loosening or displacement due to loose fixation, so as to avoid affecting the stability and safety of the lifting device 10 and the lifting platform 70.

[0099] Ginseng Fig.13 As shown, a single guide rail 81 is composed of a plurality of guide rail segments (e.g., Fig.13The guide rail segment 814 and the guide rail segment 815 shown in the figure are sequentially spliced ​​along the outer facade 202 of the buttress column 201, thereby facilitating the installation and fixation of the guide rail 81. At the same time, the embedded part 82 is arranged on the back side of the joint of two guide rail segments (for example, guide rail segment 814 and guide rail segment 815) to ensure stable assembly of the guide rail segment joint, and preferably, only one plate 821 is embedded in the joint of the two guide rail segments, and the assembly of the guide rail segments is achieved under the joint action of pads 83 and external pressure plates 84 of different thicknesses, so that the guide rail segments 814 and 815 of the buttress column 201 arranged on the cylinder 210 can be in the same vertical plane, and the guide rail segments 814 and 815 of the buttress column arranged on the hemispherical dome 220 can be arranged along the curved surface of the hemispherical dome 220, and ensure the smoothness of the joint of the two guide rail segments to avoid jamming of the lifting device 10 and the lifting platform 70 during the movement along the guide rail 81.

[0100] Ginseng Figures 14 to 16 As shown, the embedded part 82 includes: a plate body 821 at least partially embedded in the buttress column 201, a plurality of fixed columns 822 arranged on the plate body 821 and extending toward the buttress column 201 to form a plurality of fixed columns 822 embedded in the buttress column 201, and the ends of the fixed columns 822 form fixed blocks 823 embedded in the buttress column 201. The fixed blocks 823 and the fixed columns 822 are both embedded in the buttress column 201, and the plate body 821 is at least partially embedded in the buttress column 201, thereby making the embedded part 82 embedded in the buttress column 201 to achieve the fixation of the embedded part 82. The plurality of fixed columns 822 are evenly arranged on the surface of one side of the plate body 821, and accordingly, the fixed blocks 823 are formed at the ends of the buttress column 201 to ensure the stability of the embedded part 82 inside the buttress column 201 in multiple directions. As for the installation method of the plate body 821, it can be partially embedded in the buttress 201, or it can be fully embedded in the buttress 201, thereby ensuring further stability of the embedded part 82, and if the plate body 821 is fully embedded in the buttress 201, the surface of the plate body 821 facing away from the fixing column 822 is flush with the surface of the buttress 201.

[0101] Specifically, Fig.15As shown, the adjacent guide rail section 814 and guide rail section 815 are used as examples for exemplary description. The guide rail section 814 forms a first mounting portion 8141 on the inner side of the guide rail section 815, and the guide rail section 815 forms a second mounting portion 8151 on the inner side of the guide rail section 814. The first mounting portion 8141 and the second mounting portion 8151 are continuously penetrated by a locking mechanism (for example, bolts and nuts, etc.) to achieve stable assembly of the guide rail section 814 and the guide rail section 815. The outer side of the guide rail section 814 is convexly provided with a first rack section 8142, and the outer side of the guide rail section 815 is convexly provided with a second rack section 8152. When the guide rail section 814 and the guide rail section 815 are assembled, the first rack section 8142 and the second rack section 8152 are spliced ​​to form a rack for the lifting device 10 and the lifting platform 70 to move. At the same time, the rack is protruding outside relative to the guide rail 81, and due to its good tooth height design and structural strength, it can effectively support the safe movement of the lifting device 10 and the lifting platform 70 and reduce safety hazards.
