Description

Technical Field

[0001] The present invention specifically relates to a tower crane for tower construction and its curtain wall installation system, belonging to the technical field of construction equipment. Background Art

[0002] In the traditional tower construction process, curtain wall installation is a complex and time-consuming link. Usually, a steel structure scaffolding is erected to assist the construction. This steel structure scaffolding needs to be erected in multiple layers to meet the construction requirements at different heights of the tower. An elevator is installed manually on the scaffolding to gradually transport building materials upward. This method has the following main problems: First, it is necessary to erect multiple layers of steel structure scaffolding, which not only increases the complexity of construction but also raises the construction cost. And by installing an elevator manually on the scaffolding and gradually transporting building materials, this method is inefficient. Construction workers operate on a narrow scaffolding platform, making it difficult to ensure the accuracy and quality of curtain wall installation. It is also easily affected by weather and human factors, resulting in construction progress delays and the construction effect being difficult to guarantee. Second, with the increase in height and the stacking of materials, the pressure borne by the bottom steel structure will continuously increase. The existing bottom steel structure needs to bear a large load, but the traditional method does not effectively reinforce and support it. This not only affects the stability and support effect of the entire bracket but may even cause partial or overall fracture and collapse of the steel structure scaffolding in extreme cases, leading to safety accidents, and seriously affecting the construction efficiency of the entire tower curtain wall.

[0003] Therefore, it is necessary for our company to propose an improvement to a tower crane for tower construction and its curtain wall installation system to improve the efficiency, safety, and construction quality of tower curtain wall installation. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a tower crane for tower construction to solve the problems mentioned in the above background art.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: A tower crane for tower construction includes a cylindrical tower, a plurality of foundation embedded parts arranged around the outer periphery of the cylindrical tower, a foundation bottom section locked and installed on the top of the foundation embedded parts, and a plurality of connection sections spliced and locked on the upper side of the foundation bottom section, thus forming a plurality of vertically erected frames distributed in a ring shape. A plurality of ring beam sleeve frames are slidably sleeved on each of the vertically erected frames, and a ring beam is integrally installed between each of the ring beam sleeve frames. A plurality of double-layer telescopic platforms are annularly and movably installed inside the ring beam for rotating annularly around the outside of the cylindrical tower. And a telescopic component extending towards the cylindrical tower is arranged on the opposite side of the double-layer telescopic platform. A tightening component for pressing against the outer peripheral surface of the cylindrical tower is installed on one side of the telescopic component. A reinforcement support component is fixedly connected between the foundation bottom section and the connection section, and the bottom of the reinforcement support component is fixedly connected to the ground.

[0006] The reinforcement support assembly includes a front fixing plate, a rear fixing plate, a left fixing plate, and a right fixing plate that are oppositely arranged in the front, rear, left, and right directions and are detachably connected. Four insertion rods and four outer sleeve rods are arranged on the opposite sides of the front fixing plate and the rear fixing plate.

One end of the insertion rod is fixedly provided with a handwheel and is rotatably installed on the outer side of the front fixing plate;

[0007] Among them, the two upper outer sleeve rods are inserted and clamped by the lower cross bar of the connecting section, and the other two lower outer sleeve rods are inserted and clamped by the upper cross bar of the foundation bottom section, so that the foundation bottom section and the connecting section can be clamped, supported, and limited in the up and down, left and right, and front and rear directions;

[0008] Limiting holes are provided on both the left and right sides of the front fixing plate and the rear fixing plate. L-shaped blocks that can be inserted into the limiting holes are respectively fixedly provided on the front and rear sides of the left fixing plate and the right fixing plate. Each side locking plate is integrally provided on one side of the L-shaped block. The side locking plate is locked and connected to the front fixing plate and the rear fixing plate by screws. The outer sides of the front fixing plate, the rear fixing plate, the left fixing plate, and the right fixing plate are all fastened to the ground by ground nails.

[0009] On the basis of the above technical solution, the left fixing plate and the right fixing plate have the same structure. The structure of the left fixing plate includes a first sleeve frame and a second insertion frame that are slidably sleeved in the front and rear directions. Inner sliding grooves are provided inside the first sleeve frame, and the second insertion frame is slidably inserted into the inner sliding grooves. The two L-shaped blocks are respectively arranged on the opposite sides of the first sleeve frame and the second insertion frame and correspond to the notches on the left and right sides of the front fixing plate and the rear fixing plate.

[0010] On the basis of the above technical solution, reinforcing ribs are respectively fixedly provided on the four sides of the foundation bottom section. Notches adapted to the reinforcing ribs are provided on the opposite sides of the front fixing plate, the rear fixing plate, the left fixing plate, and the right fixing plate.

[0011] On the basis of the above technical solution, each of the vertical stands is installed with a plurality of climbing members, and an upper operation ring platform is integrally installed between the tops of the climbing members. The climbing members are installed with first hoists. The first hoists are connected to the ring beam sleeve through steel wires and are used to retract and release the ring beam sleeve for lifting and lowering. Among them, the inner side of the ring beam sleeve is connected to the outer side of the vertical stand through a plurality of rollers. A plurality of clamping and reversing boxes are installed in the middle of the ring beam sleeve and are used to clamp the ring beam sleeve on the horizontally arranged cross bars of the vertical stand.

[0012] On the basis of the above technical solution, a second hoist is installed on the upper side of the double-layer telescopic platform. The second hoist is connected to a hook through a steel wire and is used to lift the ground materials upward and assemble them on the outer side of the column-shaped tower on the double-layer telescopic platform.

[0013] On the basis of the above technical solution, the double-layer telescopic platform includes a main support frame, a superior platform and an inferior platform fixedly arranged at intervals on one side of the main support frame. The upper and lower sides of the main support frame are movably connected to the ring beam. The second hoist is installed on the upper side of the superior platform. Two telescopic components are provided and are respectively arranged on one side of the superior platform and the inferior platform. The front end of the telescopic component of the superior platform is rotatably connected to a roller for rolling and placing the steel wire connected to the second hoist.

[0014] On the basis of the above technical solution, the telescopic component includes a first telescopic platform movably embedded in the inner sides of the superior platform and the inferior platform, and hydraulic telescopic rods for pushing and pulling the first telescopic platform to expand and contract are installed on the lower sides of the superior platform and the inferior platform. A second telescopic platform is movably embedded and installed inside the first telescopic platform, and a hydraulic telescopic rod for pushing and pulling the second telescopic platform to expand and contract is installed on the lower side of the first telescopic platform. The top pressing component includes an outer telescopic rod installed at one end of the second telescopic platform. The end of the outer telescopic rod is movably connected to a universal top plate through a ball head rod. A layer of anti-slip rubber pad is attached to the outside of the universal top plate, and it is in close contact with the outer surface of the columnar tower through the anti-slip rubber pad.

[0015] On the basis of the above technical solution, the ring beam is installed with a steel ring hanging groove. A T-shaped slider slidably hung on the steel ring hanging groove is installed on one side of the main support frame. A plurality of limiting sliding grooves are provided on the ring beam. The main support frame is installed with a plurality of rolling pulleys adapted to slide in the limiting sliding grooves. A circular gear ring is fixedly arranged on the upper side of the ring beam. The main support frame is rotatably connected with a plurality of traveling gears that can be engaged in the tooth openings of the circular gear ring, and the main support frame is also installed with a traveling motor for driving the rotation of each traveling gear.

[0016] On the basis of the above technical solution, side outer clamping plates are respectively protruded downward on the four sides of the bottom of the connecting section, and the side outer clamping plates on the four sides of the bottom are clamped on the four sides of the top of the base bottom section for limiting. Limiting cone heads are respectively fixedly arranged on the four sides of the top surfaces of the base bottom section and the connecting section, and a limiting groove adapted to the limiting cone head is provided on the bottom surface of the connecting section. A plurality of wall-attaching members are connected between the vertical upright frame and the columnar tower.

[0017] It also includes a curtain wall installation system, including the tower crane for tower construction as described above.

[0018] By adopting the above technical solution, the present invention has the following advantages:

[0019] The structure of the present invention is simple and ingenious. A reinforcement support component capable of being quickly disassembled and assembled is provided between the base bottom section and the connecting section. The reinforcement support component is locked to the bottom surface by ground nails for auxiliary support, and four outer sleeve rods are used to effectively clamp the base bottom section and the connecting section together, improving the tightness of the connection and also limiting the positions of the base bottom section and the connecting section in the front, rear, left, right, up, and down directions, preventing dislocation and collapse, and being able to provide good support for the base bottom section and improving the service strength.

[0020] At the same time, since the front fixing plate of the reinforcement support component is inserted into the outer sleeve rod of the rear fixing plate through the insertion rod, it can not only improve the overall support strength of the outer sleeve rod, but also conveniently control and adjust the clamping distance between the front fixing plate and the rear fixing plate by using threads, so as to adapt to the different widths of the base bottom section and the connecting section, greatly improving the applicability. Moreover, L-shaped blocks are fixedly provided on both sides of the left fixing plate and the right fixing plate to be inserted into the limiting holes of the front fixing plate and the rear fixing plate, connecting the entire structure into a whole and clamping it between the base bottom section and the connecting section, providing a good limiting and supporting effect. In addition, the first sleeve frame and the second insertion frame of the left fixing plate and the right fixing plate can be slidably sleeved, enabling the L-shaped blocks on both sides to adapt to the limiting holes at different distances of the front fixing plate and the rear fixing plate, improving the use flexibility.

[0021] In the present invention, the base bottom section and multiple connecting sections are spliced and clamped with each other by bolts and limiting cone heads to form an integral vertical stand. The outer clamping plates on the four sides of the bottom of the connecting section are clamped on the adjacent base bottom section or connecting section below, further playing a limiting effect in the front, rear, left, and right directions. On this basis, combined with the firm support of the above-mentioned reinforcement support component, the stability of the vertical stand can be greatly improved. Moreover, multiple wall-attaching members are connected between each vertical stand and the column-shaped tower platform to ensure the overall stability. At the same time, the setting of the wall-attaching members can also play a supporting effect when the climbing member and the ring beam sleeve suddenly fall, providing a strong guarantee for the use safety.

[0022] Each vertical stand can use the climbing member to gradually lift the upper operation ring platform upwards to the required height. Then, by winding and unwinding the ring beam sleeve by the first winch, the ring beam and the double-layer telescopic platform can quickly rise and fall along the vertical stand to the required construction height, and cooperate with the telescopic component to adapt to the uneven surface position of the column-shaped tower platform, and cooperate with the second winch to hoist materials to the lower platform for construction. Moreover, the double-layer telescopic platform can move annularly along the circular tooth ring on the upper side of the ring beam, so as to quickly adjust to different positions on the surface of the column-shaped tower platform, making the installation of the curtain wall simpler and more flexible, and greatly improving the overall construction efficiency and effect.

[0023] When the above-mentioned telescopic component extends, it can cooperate with the extension of the jacking component to make the universal top plate rotate to fit the surface of the jacking cylindrical tower, so that the force acts on the cylindrical tower and the ring beam. This can not only improve the stability of the double-layer telescopic platform on the ring beam, but also strengthen the stability of the overall structure, effectively preventing the collapse of the vertical stand and the fall of the double-layer telescopic platform.

Specific embodiments

[0039] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] As Figure 1-13 shown in the figure, the present invention provides a technical solution for a tower crane for tower construction, including a column-shaped tower platform 1, a plurality of foundation embedded parts 2 arranged around the outer periphery of the column-shaped tower platform 1, a bottom section of the foundation 21 fixedly installed on the top of the foundation embedded parts 2, and a plurality of connecting sections 3 spliced and locked on the upper side of the bottom section of the foundation 21, thereby forming six vertically arranged uprights 31 distributed in a ring shape and distributed along the periphery of the column-shaped tower platform 1, so as to support the load forces in all directions. A plurality of ring beam sleeves 6 are slidably sleeved on each of the vertical uprights 31, and a ring beam 61 is integrally installed between the ring beam sleeves 6. A plurality of double-layer telescopic platforms 7 are annularly and movably installed inside the ring beam 61 for rotating annularly around the outer side of the column-shaped tower platform 1, so as to correspond to different surface positions of the column-shaped tower platform 1, which is simple and convenient to use. And a telescopic assembly 71 extending towards the column-shaped tower platform 1 is arranged on the opposite side of the double-layer telescopic platform 7. The telescopic assembly 71 can extend outwards to adapt to the uneven positions of the column-shaped tower platform 1. A tightening assembly for pressing against the outer peripheral surface of the column-shaped tower platform 1 is installed on one side of the telescopic assembly 71, improving the fixing effect of the double-layer telescopic platform 7 and making the use more stable and safe.

[0041] Moreover, in this embodiment, a reinforcement support assembly 8 is fixedly connected between the base bottom section 21 and the connecting section 3. The bottom of the reinforcement support assembly 8 is fixedly connected to the ground and is used to support the bottom support and stability of the steel structure vertical stand 31. Specifically, the reinforcement support assembly 8 includes a front fixing plate 81, a rear fixing plate 82, a left fixing plate 83, and a right fixing plate 84 that are oppositely arranged in the front, rear, left, and right directions and are detachably connected, enabling the base bottom section 21 and the connecting section 3 to be clamped and supported and limited in the up, down, left, right, front, and rear directions. Four insertion rods 811 and four outer sleeve rods 821 are arranged on the opposite sides of the front fixing plate 81 and the rear fixing plate 82, and the outer sleeve rods 821 are respectively sleeved on the insertion rods 811. One of the insertion rods 811 is provided with a thread 812 and is threadedly connected to the inner side of the outer sleeve rod 821. One end of the insertion rod 811 is fixedly provided with a handwheel 813 and is rotatably installed on the outer side of the front fixing plate 81. This not only improves the overall support strength of the outer sleeve rod 821 but also conveniently controls the clamping distance between the front fixing plate 81 and the rear fixing plate 82, adapts to the different widths of the base bottom section 21 and the connecting section 3, improves the adaptability of the reinforcement support assembly 8 to the bottom structure of the vertical stand 31, and further enhances the tightness of the connection between the base bottom section 21 and the connecting section 3, further improving the support effect at the bottom of the vertical stand 31;

[0042] Among them, the two upper outer sleeve rods 821 are inserted and clamped by the lower cross bar of the connecting section 3, and the two lower outer sleeve rods 821 are inserted and clamped by the upper cross bar of the base bottom section 21. This setting effectively restricts the displacement of the base bottom section 21 and the connecting section 3 in all directions, thereby enhancing the stability of the bottom of the steel structure vertical stand 31. Especially when the columnar tower 1 is subjected to lateral wind force or pressure generated by its own structural load, this all-round limitation can prevent misalignment or loosening between the base bottom section 21 and the connecting section 3, ensuring the integrity of the bottom structure of the vertical stand 31;

[0043] Limit holes 87 are provided on both the left and right sides of the front fixing plate 81 and the rear fixing plate 82. L-shaped blocks 88 that can be inserted into the limit holes 87 are respectively fixedly provided on the front and rear sides of the left fixing plate 83 and the right fixing plate 84. One side of the L-shaped block 88 is integrally provided with side locking plates 881, and the side locking plates 881 are locked and connected to the front fixing plate 81 and the rear fixing plate 82 by screws to form an integral structure. This integral structure is fastened to the ground by ground nails 85, firmly fixing the bottom of the vertical stand 31 to the ground, providing a reliable support foundation for the entire tower structure, and effectively enhancing the stability of the entire tower structure. When natural disasters such as earthquakes occur, this stable integral structure can better resist the impact of seismic waves, reducing the risk of shaking, tilting, or even collapsing at the bottom of the vertical stand 31, thereby ensuring the safety of the entire columnar tower 1 and the tower crane;

[0044] Among them, the left fixing plate 83 and the right fixing plate 84 have the same structure. The structure of the left fixing plate 83 includes a first sleeve 841 and a second insertion frame 843 that are slidably sleeved front and back. An inner sliding groove 842 is provided inside the first sleeve 841, and the second insertion frame 843 is slidably inserted into the inner sliding groove 842. Two L-shaped clamping blocks 88 are respectively arranged on the opposite sides of the first sleeve 841 and the second insertion frame 843, and correspond to the notches 86 on the left and right sides of the front fixing plate 81 and the rear fixing plate 82. This enables the reinforcement and support assembly 8 to well adapt to different width dimensions of the vertical stand 31, and can effectively play a supporting and stabilizing role in the construction of tower platforms of different scales, further improving the practicality and effectiveness of the assembly in enhancing the overall structural stability. Among them, the inner convex edge and the outer convex edge that are mutually adapted are provided on the notch of the inner sliding groove 842 and one side of the second insertion frame 843. After being fully pulled apart, the outer convex edge of the second insertion frame 843 can be clamped on the inner convex edge of the inner sliding groove 842 to avoid direct detachment and reduce the pulling force of the support. Moreover, reinforcing ribs 22 are respectively fixed on the four sides of the base bottom section 21 to improve the self-supporting strength of the base bottom section 21. Notches 86 adapted to the reinforcing ribs 22 are provided on the opposite sides of the front fixing plate 81, the rear fixing plate 82, the left fixing plate 83, and the right fixing plate 84, so as to be flexibly staggered, avoiding interference between the reinforcement and support assembly and the reinforcing ribs 22 on the base bottom section 21, ensuring that the reinforcement and support assembly 8 can be accurately and firmly installed in place. During the actual installation process, construction workers can conveniently install the reinforcement and support assembly 8 at the predetermined position without the need for additional adjustment or removal of the reinforcing ribs 22 of the base bottom section 21, improving the installation efficiency and also ensuring that the originally designed supporting strength of the base bottom section 21 is not affected. Moreover, this adaptability design of the reinforcement and support assembly 8 and the base bottom section 21 helps to better transfer the supporting force of the reinforcement and support assembly to the base bottom section 21. By reinforcing the base bottom section 21 and the connecting section 3 through the reinforcement and support assembly 8, and combined with the strengthening effect of the self-reinforcing ribs 22 of the base bottom section 21, the stability of the bottom structure of the tower platform is overall enhanced, providing a more reliable foundation guarantee for the construction of the entire tower platform.

[0045] In this embodiment, a plurality of climbing members 4 are installed on each vertical stand 31. The climbing members 4 are also provided with a clamping and reversing box 60. An upper operation ring platform 5 is integrally installed between the tops of the climbing members 4. The climbing member 4 is a lifting device already disclosed in a construction integrated aerial tower crane for airport tower construction curtain wall, with a Chinese patent publication number of CN119392901A applied by our company independently. Therefore, it will not be elaborated here. A first winch 41 is installed on the climbing member 4. The first winch 41 is connected to the ring beam sleeve 6 through a steel wire rope and is used to retract and release the ring beam sleeve 6 for lifting and lowering. The inner side of the ring beam sleeve 6 is connected to the outer side of the vertical stand 31 through a plurality of rollers, reducing the friction therebetween and improving the smoothness and mobility during height adjustment. The height of the ring beam sleeve 6, the ring beam 61, and the double-layer telescopic platform 7 can be adjusted as needed, enabling construction workers to reach a suitable working position.

[0046] A plurality of clamping and reversing boxes 60 are installed in the middle of the ring beam sleeve 6 and are used to place the ring beam sleeve 6 on the horizontally arranged cross bar of the vertical stand 31. The clamping and reversing box 60 mainly includes a rotatably installed clamping block, which can rotate inward under the action of a hydraulic telescopic rod and thus be clamped on the cross bar of the vertical stand 31, fixing and supporting the ring beam sleeve 6, the ring beam 61, and the double-layer telescopic platform 7 in the middle of the vertical stand 31, that is, reducing the pulling force of the first winch 41 and preventing falling downward.

[0047] A second winch 75 is installed on the upper side of the double-layer telescopic platform 7. The second winch 75 is connected to a hook 751 through a steel wire rope and is used to lift ground materials upward and assemble them outside the columnar tower 1 on the double-layer telescopic platform 7, facilitating the transportation of construction materials. For example, curtain wall materials can be hoisted to a suitable construction height, improving construction efficiency. The double-layer telescopic platform 7 includes a main support frame 70, and a superior platform 701 and an inferior platform 702 fixedly arranged at intervals on one side of the main support frame 70. The upper and lower sides of the main support frame 70 are movably connected to the ring beam 61. The second winch 75 is installed on the upper side of the superior platform 701. There are two telescopic assemblies 71, which are respectively arranged on one side of the superior platform 701 and the inferior platform 702. The front end of the telescopic assembly 71 of the superior platform 701 is rotatably connected to a roller 713 for rolling the steel wire connected to the second winch 75, making the hoisting operation coordinated with the structure of the double-layer telescopic platform 7, facilitating the operation during material hoisting. And the telescopic assemblies 71 are respectively arranged on one side of the superior platform 701 and the inferior platform 702, which also helps to adjust the platform according to actual hoisting requirements to ensure the smooth progress of the hoisting work.

[0048] In this embodiment, the telescopic assembly 71 includes a first telescopic platform 711 movably embedded in the inner sides of the upper platform 701 and the lower platform 702. Hydraulic telescopic rods for pushing and pulling the first telescopic platform 711 to expand and contract are installed on the lower sides of both the upper platform 701 and the lower platform 702. A second telescopic platform 712 is movably embedded in the inner side of the first telescopic platform 711, and a hydraulic telescopic rod for pushing and pulling the second telescopic platform 712 to expand and contract is installed on the lower side of the first telescopic platform 711. Through the action of the hydraulic telescopic rods, a multi-level telescopic function can be achieved. During the construction of the tower, the extension range of the platform can be flexibly adjusted according to the actual construction requirements. Especially when constructing the surface of cylindrical towers 1 with different radii, the working range of the double-layer telescopic platform 7 can be adjusted by the expansion and contraction of the telescopic assembly 71, improving the applicability of the platform;

[0049] The tightening assembly includes an outer telescopic rod 72 installed at one end of the second telescopic platform 712. The end of the outer telescopic rod 72 is movably connected to a universal top plate 721 through a ball head rod. A layer of anti-slip rubber pad is attached to the outside of the universal top plate 721, and it is in close contact with the outer surface of the cylindrical tower 1 through the anti-slip rubber pad, improving the stability of the double-layer telescopic platform 7. When personnel walk or perform construction operations on the platform, the tightening assembly can prevent the double-layer telescopic platform 7 from shaking, ensuring construction safety and also contributing to improving construction accuracy.

[0050] In the above technical solution, a steel ring hanging groove 62 is installed on the ring beam 61. A T-shaped slider 73 slidably hung on the steel ring hanging groove 62 is installed on one side of the main support frame 70. A plurality of limit sliding grooves 64 are provided on the ring beam 61. A plurality of rolling pulleys 74 adapted to slide in the limit sliding grooves 64 are installed on the main support frame 70. In addition, a circular gear ring 63 is fixedly provided on the upper side of the ring beam 61. The main support frame 70 is rotatably connected to a plurality of traveling gears 76 that can engage in the teeth of the circular gear ring 63. The main support frame 70 is also installed with a traveling motor 77 for driving the rotation of each traveling gear 76. After the traveling gears 76 rotate, they can drive the entire double-layer telescopic platform 7 to perform a circular sliding displacement on the ring beam 61, enabling the double-layer telescopic platform 7 to quickly adjust its position according to the requirements of the construction process, conveniently moving the platform to the corresponding position, improving construction efficiency, reducing construction time and labor costs, and enhancing the flexibility and usage efficiency of the structure.

[0051] On the four sides of the bottom of the connecting section 3, there are laterally outward clamping plates 24 protruding downward respectively. The laterally outward clamping plates 24 on the four sides of the bottom are clamped on the four sides of the top of the basic bottom section 21 for limiting. On the four sides of the top surfaces of the basic bottom section 21 and the connecting section 3, there are limiting cone heads 25 fixedly arranged respectively. And on the bottom surface of the connecting section 3, there is a limiting groove adapted to the limiting cone head 25. The connecting section 3 and the connecting section 3, as well as the basic bottom section 21 and the connecting section 3, are inserted through the limiting cone heads 25, and are clamped at the corresponding four-side positions by the outer clamping plates 24, ensuring the accuracy and stability of the connection. And a plurality of attachment members 9 are connected between the vertical upright 31 and the columnar tower 1, for strengthening the overall stability of the vertical upright 31 and the whole columnar tower 1, and preventing the sudden fall of the ring beam sleeve 6.

[0052] More specific implementation principle: When installing the six vertical uprights 31, first lock the basic bottom section 21 and the upper side of the basic embedded part 2 with bolts. Then, align each connecting section 3 with the limiting cone head 25 on the upper side of the basic bottom section 21 and insert it into the device, and let the outer clamping plates 24 on the four sides of the bottom of the connecting section 3 be clamped on the four sides of the top of the basic bottom section 21 or on the four sides of the top of the adjacent lower connecting section 3 for limiting, and lock them with bolts to each other. Finally, form the vertical upright 31. During this period, the climbing member 4 and the ring beam sleeve 6 are sleeved on each vertical upright 31. And an operation ring platform 5 is installed on the top of each climbing member 4, a ring beam 61 is installed on each ring beam sleeve 6, three double-layer telescopic platforms 7 are installed on the ring beam 61, and the first winch 41 on the climbing member 4 is connected to the top of the ring beam sleeve 6 through a steel wire rope. After the climbing member 4 climbs upward and jacks up the operation ring platform 5, the first winch 41 can be used to synchronously lift each ring beam sleeve 6 so that the ring beam 61 and the double-layer telescopic platform 7 can be lifted up and down to the required height.

[0053] After the double-layer telescopic platform 7 rises, the four outer rods 821 of the rear fixing plate 82 in the reinforcement support assembly 8 can be adaptively inserted and penetrated from the lower side of the top cross bar of the basic bottom section 21 and the upper side of the bottom cross bar of the connecting section 3. Then, the insertion rod 811 of the front fixing plate 81 is relatively inserted through the middle of the outer rod 821. By rotating the thread 812 of one of the insertion rods 811 with the hand wheel 813, while enhancing the strength of the outer rod 821, the front fixing plate 81 and the rear fixing plate 82 are tightly held at the positions of the basic bottom section 21 and the connecting section 3, improving the stable support of the bottom of the vertical stand 31. Moreover, the positions of its front, rear, left, right, up, and down are limited to prevent dislocation. Then, the L-shaped blocks 88 on both sides of the left fixing plate 83 and the right fixing plate 84 can be adaptively inserted into the limiting holes 87 on both sides of the front fixing plate 81 and the rear fixing plate 82 and are interconnected by screws of the side locking plate 881, so that the front fixing plate 81, the rear fixing plate 82, the left fixing plate 83, and the right fixing plate 84 form an integral body and are fastened to the ground by ground nails 85, effectively supporting and limiting the entire vertical stand 31. And the first sleeve frame 841 and the second insertion frame 843 of the left fixing plate 83 and the right fixing plate 84 can adaptively expand and contract along with the moving distance between the front fixing plate 81 and the rear fixing plate 82, and can well adapt to different width dimensions of the vertical stand 31;

[0054] And after the double-layer telescopic platform 7 rises to the required position, the cross bar on the vertical stand 31 is fixed by the block of the positioning and reversing box 60, and the telescopic components 71 of the upper platform 701 and the lower platform 702 are controlled to extend, so that the first telescopic platform 711 and the second telescopic platform 712 displace towards the uneven surface of the cylindrical tower 1. During this period, the traveling motor 77 can drive the traveling gear 76 to travel on the circular tooth ring 63 of the ring beam 61, enabling the double-layer telescopic platform 7 to rotate 360 degrees along the steel ring hanging groove 62 and the limiting sliding groove 64 of the ring beam 61, so as to correspond to different surface positions of the cylindrical tower 1, greatly improving the use flexibility. And by extending the outer telescopic rod 72, the universal top plate 721 can be adapted to tightly press against the surface of the cylindrical tower 1, and the force is applied between the cylindrical tower 1 and the ring beam 61, which can improve the stability and safety of the double-layer telescopic platform 7 on the ring beam 61. Then, the hook 751 connected by the steel wire rope of the second hoist 75 is lowered to lift the curtain wall materials on the ground to the lower platform 702 for installation. And after the double-layer telescopic platform 7 rises, multiple wall attachment members 9 can be installed between the lower vertical stand 31 and the cylindrical tower 1 below, which can be used to improve the overall stability and prevent potential safety hazards caused by the sudden drop of the ring beam sleeve 6.

[0055] In this embodiment, a curtain wall installation system is also proposed, including the above-mentioned tower crane for tower construction.
