Description

A retractable external beam for an internal climbing tower crane Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to a retractable external beam for an internal climbing tower crane. Background Technology

[0002] In the construction process of building engineering, tower cranes are usually used as the main engineering equipment for vertical transportation during the construction of the main structure. The selection and placement of tower cranes often have a significant impact on the efficient and safe construction of the project. In the construction of super high-rise buildings, especially super high-rise buildings with tube structure, the use of internal climbing tower cranes has gradually become a preferred option due to their safety and economy. The foundation schemes mainly adopt suspended foundations and ground foundations. Ground foundations are mostly used in elevator shafts of completed multi-story basement structures. When internal climbing tower cranes use ground foundations, they need to be combined with wall attachment measures, and external beams are often used to fix them.

[0003] Chinese Utility Model Patent Publication No. CN211338597U discloses: an internal climbing tower crane wall-mounted connector. This internal climbing tower crane wall-mounted connector is a device used for connecting tower cranes to the wall inside elevator shafts. It features simple manufacturing, convenient transportation, reliable connection, clear force transmission, and economic and environmental protection. The internal climbing tower crane wall-mounted connector device has advantages such as convenient material sourcing, rapid manufacturing, convenient installation and dismantling, and recyclability. However, this internal climbing tower crane wall-mounted connector does not have a side support structure, which makes it inconvenient to achieve multi-directional fixation. It is also inconvenient to adjust the angle of the side fixing structure according to different working heights, resulting in poor resistance to deformation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a retractable external beam for an internal climbing tower crane, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a retractable external beam for an internal climbing tower crane, comprising a crane standard section and a connecting frame fixedly installed at the outer edge of the crane standard section. A telescopic rod is movably connected to the end of the connecting frame away from the crane standard section. A main connecting member is fixedly installed at the end of the telescopic rod away from the connecting frame. A first mounting member is movably connected to the end of the main connecting member away from the telescopic rod. A side connecting member is fixedly installed on the side of the connecting frame away from the telescopic rod. A side connecting sleeve is rotatably connected to the end of the side connecting sleeve away from the connecting frame. A side telescopic column is movably connected to the end of the side connecting sleeve away from the side connecting member. A second mounting member is provided at the end of the side telescopic column away from the side connecting sleeve. A limit rod is provided between the crane standard section and the side telescopic column.

[0006] Preferably, a reinforcing sleeve one is fixedly installed at the end of the connecting frame away from the standard section of the crane, a reinforcing rod is provided at the end of the reinforcing sleeve one away from the connecting frame, a reinforcing member is fixedly installed at the end of the reinforcing rod away from the reinforcing sleeve one, a reinforcing sleeve two is rotatably installed at the end of the reinforcing member away from the reinforcing rod, and a third mounting member is fixedly installed at the end of the reinforcing sleeve two away from the reinforcing member.

[0007] The above technical solution involves first fixing the connecting frame to the outer edge of the standard section of the crane, and then sequentially installing the first reinforcing sleeve, the reinforcing rod, the reinforcing component, the second reinforcing sleeve, and the third mounting component. The reinforced structure can be achieved through the first reinforcing sleeve, the reinforcing rod, and other components, thereby enhancing the overall strength and stability of the external beam when bearing heavy loads during hoisting.

[0008] Preferably, a connecting post for reinforcement is welded between the connecting frame and the reinforcing sleeve, and multiple identical connecting posts are provided, with the lengths of the multiple connecting posts decreasing in a descending order.

[0009] Through the above technical solution, after the initial installation and positioning of the connecting frame and the reinforcing sleeve are completed, multiple connecting columns are welded between the connecting frame and the reinforcing sleeve in descending order of length. The multiple connecting columns with decreasing length can form a reasonable stress dispersion structure between the connecting frame and the reinforcing sleeve, effectively dispersing the stress generated during hoisting operations and avoiding structural damage caused by local stress concentration.

[0010] Preferably, a connecting seat is fixedly installed at the end of the connecting frame away from the side connector, and a connecting pin is rotatably installed at the end of the connecting seat away from the connecting frame. The connecting seat is movably connected to a connecting rod through the connecting pin.

[0011] By using the above technical solution, the connecting seat is first fixed on the connecting frame, and then the connecting pin is installed on the connecting seat. This can enhance the stability between the connecting frame and the standard section of the crane, prevent longitudinal displacement at the outer edge, and improve its stability.

[0012] Preferably, the side connector is provided with a main shaft at the end away from the connecting frame, and the side connector is movably connected to the first side connecting sleeve through the main shaft. The side telescopic column is fixedly installed with a side connecting shaft at the end away from the first side connecting sleeve, and the side connecting shaft is movably connected to the second side connecting sleeve at the end away from the side telescopic column.

[0013] The above technical solution involves first connecting the first side connecting sleeve to the side connecting piece via the main shaft, and then connecting the second side connecting sleeve to the side telescopic column via the side connecting shaft. During construction, the lateral support range of the external beam can be changed by adjusting the telescopic length of the side telescopic column according to the actual operation requirements. When the height is higher, the angle between the side telescopic column and the connecting frame can be reduced, thereby improving its resistance to deformation.

[0014] Preferably, a main sleeve is provided at one end of the main connector near the first mounting component, and the main connector is movably connected to the first mounting component through the main sleeve. A reinforcing seat one is fixedly installed at one end of the connecting frame near the side connector, and a reinforcing seat two is fixedly installed at one end of the side telescopic column near the connecting frame. A limit rod is movably connected between the reinforcing seat one and the reinforcing seat two.

[0015] Through the above technical solution, the movable connection between the main sleeve and the first mounting component facilitates the adjustment of the angle of the first mounting component, improves the adaptability to the connection with hoisting equipment, and the setting of the limit rod provides limit protection for the side telescopic column, ensuring the stability of the external beam during telescopic and operational processes.

[0016] Preferably, the connecting frame, telescopic rod, first mounting component, side connecting sleeve one, side telescopic column and second mounting component are provided in three identical sets; alternatively, the connecting frame, telescopic rod, first mounting component, side connecting sleeve one, side telescopic column and second mounting component are provided in two identical sets, and the two connecting frames, telescopic rods, first mounting components, side connecting sleeve one, side telescopic column and second mounting component are symmetrically distributed about the center line of the crane standard section.

[0017] With the above technical solution, during installation, two sets of symmetrical connecting frames, telescopic rods and other components are installed sequentially on the outer edge of the crane standard section, and then the remaining three sets of components are installed. The symmetrical distribution design of multiple sets of components ensures that the external beam can be evenly stressed during hoisting, effectively dispersing the load and avoiding deformation of the crane standard section and external beam structure due to uneven stress.

[0018] Compared with the prior art, this utility model provides a retractable external beam for an internal climbing tower crane, which has the following beneficial effects:

[0019] 1. The telescopic external beam of this internal climbing tower crane can change the lateral support range of the external beam by adjusting the telescopic length of the side telescopic column according to the actual operation requirements during construction, and then limiting the welding or other fixing parts of the two. Furthermore, when the working height is higher, the included angle between the side telescopic column and the connecting frame can be reduced, which can provide multi-directional fixation and improve its resistance to deformation.

[0020] 2. During installation, the telescopic external beam of this internal climbing tower crane is installed by sequentially installing two sets of symmetrical connecting frames, telescopic rods and other components on the outer edge of the crane's standard section, and then installing the remaining three sets of components. The symmetrical distribution design of multiple sets of components ensures that the external beam can be evenly stressed during hoisting, effectively distributing the load and avoiding deformation of the crane's standard section and external beam structure due to uneven stress.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: As shown in Figures 1-6, the present invention provides a retractable external beam for an internal climbing tower crane, including a crane standard section 1 and a connecting frame 2 fixedly installed on the outer edge of the crane standard section 1. A telescopic rod 3 is movably connected to the end of the connecting frame 2 away from the crane standard section 1. A main connecting member 4 is fixedly installed at the end of the telescopic rod 3 away from the connecting frame 2. A first mounting member 6 is movably connected to the end of the main connecting member 4 away from the telescopic rod 3. A side connecting member 7 is fixedly installed on the side of the connecting frame 2 away from the telescopic rod 3. A side connecting sleeve 9 is rotatably connected to the end of the side connecting sleeve 9 away from the side connecting member 7. A side telescopic column 10 is movably connected to the end of the side telescopic column 10 away from the side connecting sleeve 9. A second mounting member 13 is provided at the end of the side telescopic column 10 away from the side connecting sleeve 9. A limit rod 15 is provided between the crane standard section 1 and the side telescopic column 10.

[0030] Specifically, a reinforcing sleeve 17 is fixedly installed at the end of the connecting frame 2 away from the standard section 1 of the crane. A reinforcing rod 18 is provided at the end of the reinforcing sleeve 17 away from the connecting frame 2. A reinforcing member 19 is fixedly installed at the end of the reinforcing rod 18 away from the reinforcing sleeve 17. A reinforcing sleeve 20 is rotatably installed at the end of the reinforcing member 19 away from the reinforcing rod 18. A third mounting member 21 is fixedly installed at the end of the reinforcing sleeve 20 away from the reinforcing member 19. The advantage is that the connecting frame 2 is first fixed to the outer edge of the standard section 1 of the crane, and then the reinforcing sleeve 17, reinforcing rod 18, reinforcing member 19, reinforcing sleeve 20 and third mounting member 21 are installed in sequence. The reinforcing structure can be strengthened through the reinforcing sleeve 17, reinforcing rod 18 and other components, which enhances the overall strength and stability of the external beam when bearing heavy loads.

[0031] Specifically, connecting columns 22 for reinforcement are welded between the connecting frame 2 and the reinforcing sleeve 17. Multiple connecting columns 22 are provided, and the lengths of the multiple connecting columns 22 are distributed in descending order. The advantage is that after the initial installation and positioning of the connecting frame 2 and the reinforcing sleeve 17 are completed, multiple connecting columns 22 are welded between the connecting frame 2 and the reinforcing sleeve 17 in descending order of length. The multiple connecting columns 22 with descending lengths can form a reasonable stress dispersion structure between the connecting frame 2 and the reinforcing sleeve 17, effectively dispersing the stress generated during hoisting operations and avoiding structural damage caused by local stress concentration.

[0032] Specifically, a connecting seat 23 is fixedly installed at the end of the connecting frame 2 away from the side connecting piece 7, and a connecting pin 24 is rotatably installed at the end of the connecting seat 23 away from the connecting frame 2. The connecting seat 23 is movably connected to the connecting rod 25 through the connecting pin 24. The advantage is that by first fixing the connecting seat 23 to the connecting frame 2 and then installing the connecting pin 24 on the connecting seat 23, the stability between the connecting frame 2 and the crane standard section 1 can be enhanced, preventing longitudinal displacement at the outer edge and improving its stability.

[0033] Example 2: As shown in Figures 2-6, this is an improvement on the previous example.

[0034] Specifically, a main shaft 8 is provided at the end of the side connector 7 away from the connecting frame 2. The side connector 7 is movably connected to the side connecting sleeve 1 9 through the main shaft 8. A side connecting shaft 11 is fixedly installed at the end of the side telescopic column 10 away from the side connecting sleeve 1 9. A side connecting sleeve 2 12 is movably connected at the end of the side connecting shaft 11 away from the side telescopic column 10. The advantage is that the side connecting sleeve 1 9 is first movably connected to the side connector 7 through the main shaft 8, and then the side telescopic column 10 is movably connected to the side connecting sleeve 2 12 through the side connecting shaft 11. During construction, the lateral support range of the external beam can be changed by adjusting the telescopic length of the side telescopic column 10 according to the actual operation requirements. When the height is higher, the included angle between the side telescopic column 10 and the connecting frame 2 can be reduced, thereby improving its resistance to deformation.

[0035] Specifically, a main sleeve 5 is provided at the end of the main connector 4 near the first mounting part 6. The main connector 4 is movably connected to the first mounting part 6 through the main sleeve 5. A reinforcing seat 14 is fixedly installed at the end of the connecting frame 2 near the side connector 7. A reinforcing seat 26 is fixedly installed at the end of the side telescopic column 10 near the connecting frame 2. A limit rod 15 is movably connected between the reinforcing seat 14 and the reinforcing seat 2. The advantage is that the movable connection between the main sleeve 5 and the first mounting part 6 makes it easy to adjust the angle of the first mounting part 6, which improves the adaptability to the connection with the hoisting equipment. The setting of the limit rod 15 provides limit protection for the side telescopic column 10, ensuring the stability of the external beam during telescopic and operation processes.

[0036] Specifically, the connecting frame 2, telescopic rod 3, first mounting component 6, side connecting sleeve 9, side telescopic column 10, and second mounting component 13 are provided in three identical sets. Alternatively, two identical connecting frames 2, telescopic rod 3, first mounting component 6, side connecting sleeve 9, side telescopic column 10, and second mounting component 13 are provided. The two sets of connecting frames 2, telescopic rod 3, first mounting component 6, side connecting sleeve 9, side telescopic column 10, and second mounting component 13 are symmetrically distributed about the center line of the crane standard section 1. The advantage is that during installation, the two sets of symmetrical connecting frames 2, telescopic rod 3, and other components are installed sequentially on the outer edge of the crane standard section 1, and then the remaining three sets of components are installed. The symmetrical distribution design of multiple sets of components allows the external beam to be evenly stressed during hoisting, effectively distributing the load and avoiding deformation of the crane standard section 1 and the external beam structure due to uneven stress.

[0037] Working Principle: During use, two sets of symmetrical connecting frames 2, telescopic rods 3, and other components are sequentially installed on the outer edge of the crane standard section 1, followed by the installation of the remaining three sets of components. The symmetrical distribution design of multiple sets of components ensures that the external beam is evenly stressed during hoisting, effectively distributing the load and preventing deformation of the crane standard section 1 and the external beam structure due to uneven stress. The movable connection between the main sleeve 5 and the first mounting component 6 facilitates adjustment of the angle of the first mounting component 6, improving its compatibility with hoisting equipment. The setting of the limit rod 15 provides limit protection for the side telescopic column 10, ensuring the stability of the external beam during telescopic movement and operation. First, the side connecting sleeve 1 9 is movably connected to the side connecting component 7 via the main shaft 8, and then the side telescopic column 10 is movably connected to the side connecting sleeve 2 12 via the side connecting shaft 11. During construction, the lateral support range of the external beam is changed by adjusting the telescopic length of the side telescopic column 10 according to actual operational requirements. When the height is higher, the included angle between the side telescopic column 10 and the connecting frame 2 can be reduced. The smaller size improves its resistance to deformation. The connecting seat 23 is fixed on the connecting frame 2, and then the connecting pin 24 is installed on the connecting seat 23. This enhances the stability between the connecting frame 2 and the standard section 1 of the crane, preventing longitudinal displacement at the outer edge and improving its stability. After the initial installation and positioning of the connecting frame 2 and the reinforcing sleeve 17 are completed, multiple connecting columns 22 are welded between the connecting frame 2 and the reinforcing sleeve 17 in descending order of length. The multiple connecting columns 22 with decreasing length can form a reasonable stress dispersion structure between the connecting frame 2 and the reinforcing sleeve 17, effectively dispersing the stress generated during hoisting operations and avoiding structural damage caused by local stress concentration. First, the connecting frame 2 is fixed to the outer edge of the standard section 1 of the crane. Then, the reinforcing sleeve 17, reinforcing rod 18, reinforcing member 19, reinforcing sleeve 20 and the third mounting member 21 are installed in sequence. The reinforcing structure can be achieved through the reinforcing sleeve 17, reinforcing rod 18 and other components, which enhances the overall strength and stability of the external beam when bearing heavy loads during hoisting.
