Description

Technical Field

[0001] This utility model relates to the field of tower crane wind protection technology, specifically a wind protection device for ultra-high-rise luffing tower cranes. Background Technology

[0002] A high-rise luffing jib tower crane is a type of lifting equipment used in the construction of high-rise buildings. It typically consists of a tower, jib, hoisting mechanism, and operator's cab. The tower is usually installed on top of the building, and the jib and hoisting mechanism are used to lift and move building materials and equipment. Due to its large lifting capacity and long working radius, it is suitable for construction operations on high-rise building sites. High-rise luffing jib tower cranes can perform efficient and safe lifting operations even under high building height and wind speed conditions, making them one of the most commonly used and important pieces of equipment in modern construction. Wind protection for high-rise luffing jib tower cranes refers to safety measures implemented to prevent wind damage to luffing jib tower cranes used on high-rise building construction sites. Because high-rise building construction sites are often affected by strong winds, wind-resistant design and reinforcement of the luffing jib tower cranes are necessary to ensure their safe operation under adverse weather conditions.

[0003] Under current technological conditions, we typically use steel structural supports with stable structures for assembly and support work. These steel structural supports are usually in the form of triangular frames. However, in actual operation, due to the height of some tower cranes, these frames are easily affected by strong winds, leading to deformation. Under long-term and repeated deformation, the metal frame may become fatigued, causing tower crane safety accidents. Furthermore, in some high tower cranes, workers often use ladders for ascending and descending. These ladders are usually directly fixed to the metal frame. When affected by wind, the ladders will sway, and the wind force will directly act on the workers, posing a threat to their lives. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a windproof device for ultra-high-rise luffing jib tower cranes. It has the following beneficial effects:

[0018] 1. This utility model provides a windproof device for ultra-high-rise luffing jib tower cranes. Before installation, the windproof device first investigates the possible wind direction and speed during construction to determine the number of windproof frame mechanisms. The higher the wind speed, the more windproof frame mechanisms are used to replace the support frame mechanism, which ultimately improves stability and reduces cost. In windy weather, the first and second stabilizing rods will be subjected to greater compressive force, which will drive the internal slider to slide. During the sliding process, the force on the first and second stabilizing rods will be absorbed. At the same time, the airflow will first enter the interior of the wind tunnel column through the interior of multiple air intakes, and then enter the interior of the sealed telescopic rod through the airflow channel and air inlet connected to the wind tunnel column. At this time, the sealed telescopic rod will compress the internal slider, thereby improving the absorption effect through airflow compression, thus improving the wind resistance of this windproof device.

[0019] 2. This utility model provides a windproof device for ultra-high-rise luffing jib tower cranes. In this windproof device, workers can enter the control room through a climbing mechanism. During the climbing process, when the climbing mechanism encounters strong winds, the main climbing cylinder will deform first, resulting in relative displacement between the windproof frame mechanism and the support frame mechanism. At this time, the energy-absorbing spring will deform according to the magnitude of the relative displacement, thereby absorbing the energy during the relative displacement, achieving buffering, and improving the safety of workers climbing. Furthermore, by absorbing the force that causes the wind-induced deformation of the windproof frame mechanism, the wind resistance of this windproof device is further improved.

Detailed Implementation

[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:

[0030] like Figure 1-2 As shown, this utility model embodiment provides a windproof device for a super high-rise luffing jib tower crane, including multiple support frame mechanisms 5 and windproof frame mechanisms 4. The windproof frame mechanism 4 is disposed between two of the multiple support frame mechanisms 5. The uppermost of the multiple support frame mechanisms 5 has a support base plate 3 fixedly installed inside. An upper climbing tube 1 is provided through one side of the support base plate 3. An upper outlet 2 is opened on one side of the upper climbing tube 1. An upper connecting frame 7 is fixedly installed at the upper end of the uppermost of the multiple support frame mechanisms 5. A control room 8 is fixedly installed on one side of the uppermost of the multiple support frame mechanisms 5. A safety door 10 is hinged at the opening on one side of the control room 8. A reinforcing frame 9 is fixedly installed at the lower end of the control room 8.

[0031] Specifically, in the above specific embodiment, the upper connecting frame 7 is connected to the lower end of the boom of the ultra-high-rise luffing tower crane, which can drive it to move. When the workers rise up to the upper climbing cylinder 1 along the climbing mechanism 6, they can move to the inside of the control room 8 through the upper exit 2 and the supporting base plate 3. The operation of the ultra-high-rise luffing tower crane can be controlled through the control room 8. The safety door 10 installed on the control room 8 improves the safety inside the control room 8, and the reinforcing frame 9 improves the stability of the control room 8.

[0032] like Figure 6 As shown, a climbing mechanism 6 is provided between the multiple support frame mechanisms 5 and the windproof frame mechanism 4. The climbing mechanism 6 includes multiple main climbing tubes 602. The uppermost one of the multiple main climbing tubes 602 is fixedly provided with a corrugated connecting pipe 601. The upper end of the corrugated connecting pipe 601 is connected to the lower end of the upper climbing tube 1. A climbing ladder 603 is fixedly provided inside each of the multiple main climbing tubes 602. A connecting flange 604 is fixedly provided between the multiple main climbing tubes 602.

[0033] Specifically, in the above-described embodiment, workers can enter the interior of the control room 8 through the climbing mechanism 6. During the climbing process, when the climbing mechanism 6 encounters strong winds, the main climbing tube 602 can deform through the corrugated connecting pipe 601 to generate relative displacement with the upper climbing tube 1, thereby improving the overall stability. Furthermore, the setting of the connecting flange 604 facilitates the setting of the number of main climbing tubes 602, and ultimately improves the safety of workers during the climbing process through the climbing mechanism 6.

[0034] like Figure 3-4As shown in Figure 7, the windproof frame mechanism 4 includes four wind duct columns 402. Two first stabilizing rods 401 and two second stabilizing rods 404 are fixedly installed between each pair of the four wind duct columns 402. Air intakes 403 are opened on opposite sides of each pair of the four wind duct columns 402. A reinforcing base frame 408 is fixedly installed at the lower end of each of the four wind duct columns 402. Airflow grooves 409 are opened inside each of the two first stabilizing rods 401. Sealing plates 416 are fixedly installed on both sides of each of the two airflow grooves 409 near the middle. Sealing telescopic rods 414 are fixedly installed between each pair of the four sealing plates 416. A series of sealing telescopic rods 414 are fixedly installed between each pair of the four sealing telescopic rods 414. There are two inner sliders 413, and the lower ends of the two inner sliders 413 are respectively fixedly installed on the upper ends of the two second stabilizing rods 404. The four sealing telescopic rods 414 are provided with air inlets 415 on opposite sides of each other. The lower ends of the two first stabilizing rods 401 are provided with sliding grooves 417 near the middle. The two inner sliders 413 are respectively slidably installed inside the two sliding grooves 417. The windproof frame mechanism 4 can be set to multiple. The number of windproof frame mechanisms 4 is determined by investigating the possible wind direction and wind speed during construction before installation. The higher the wind speed level, the more windproof frame mechanisms 4 are selected to replace the support frame mechanism 5, which ultimately improves stability and reduces cost.

[0035] Specifically, in the above-described embodiment, under normal operating conditions, the windproof frame mechanism 4 and the support frame mechanism 5 are stably supported and fixed by the internal wind tunnel column 402. This stable structure is further reinforced by the triangular mechanism formed by the first stabilizing rod 401 and the second stabilizing rod 404. In strong winds, this support structure is subjected to greater pressure. In this situation, the first stabilizing rod 401 and the second stabilizing rod 404 are subjected to greater compressive force, which causes the inner slider 413 to slide and absorb these forces during the sliding process. In addition, the airflow first enters the interior of the wind tunnel column 402 through multiple air inlets 403, and then enters the interior of the sealing telescopic rod 414 through the airflow channel 409 and air inlet 415 connected to the wind tunnel column 402. At this time, the sealing telescopic rod 414 applies a certain amount of compression to the inner slider 413, thereby improving the absorption effect through airflow compression, and finally offsetting the deformation generated by the windproof frame mechanism 4 by absorbing wind energy, thereby improving wind resistance.

[0036] like Figure 5A connecting block 406 is fixedly snapped onto one side of the reinforcing base 408 shown. A fixing bolt 410 is threaded through one side of the connecting block 406. Four second connecting blocks 412 are fixedly installed between the connecting block 406 and the reinforcing base 408. Energy-absorbing springs 407 are fixedly installed on opposite sides of the four second connecting blocks 412. First connecting blocks 411 are fixedly installed on opposite sides of the multiple energy-absorbing springs 407. A buffer ring 405 is fixedly installed between the four first connecting blocks 411. The buffer ring 405 is welded onto the climbing mechanism 6.

[0037] Specifically, in the above-described embodiment, by welding the buffer ring 405 onto the climbing mechanism 6, when the climbing mechanism 6 encounters strong winds during the climbing process, the deformation generated by the main climbing tube 602 and the relative displacement between the windproof frame mechanism 4 and the support frame mechanism 5 will cause the energy-absorbing spring 407 to deform according to the magnitude of the relative displacement, thereby absorbing the energy during the relative displacement, achieving buffering, improving the stability and safety during the climbing process, and absorbing some wind energy, further improving the wind resistance.

[0038] Example 2:

[0039] This utility model embodiment also provides a wind-proofing method for ultra-high-rise luffing tower cranes, specifically including the following steps:

[0040] S1. Environmental Monitoring

[0041] First, before assembling the super high-rise luffing tower crane, obtain the possible wind direction and wind speed in the construction area from the meteorological department of the construction area. Based on the common wind direction, control the air intake 403 to be parallel to the wind direction. Based on the common wind speed level, select an appropriate number of windproof frame mechanisms 4. The higher the wind speed level, the more windproof frame mechanisms 4 are selected to replace the support frame mechanism 5.

[0042] S2. Bracket Installation

[0043] The installation of the ultra-high-rise luffing tower crane is carried out according to the installation direction and the number of windproof frame mechanisms 4 as determined by the pre-installation survey.

[0044] S3. Windproof frame for wind resistance

[0045] During normal operation, the windproof frame mechanism 4 and the support frame mechanism 5 are supported and fixed by the internal wind tunnel column 402. The wind tunnel column 402 is further supported by the triangular mechanism formed by the first stabilizing rod 401 and the second stabilizing rod 404. In windy weather, the first stabilizing rod 401 and the second stabilizing rod 404 will be subjected to a large compressive force, which will cause the inner slider 413 to slide. During the sliding process, it will absorb the force on the first stabilizing rod 401 and the second stabilizing rod 404. At the same time, the airflow will first enter the interior of the wind tunnel column 402 through the interior of the multiple air intakes 403, and then enter the interior of the sealing telescopic rod 414 through the airflow channel 409 and the air inlet 415 connected to the wind tunnel column 402. At this time, the sealing telescopic rod 414 will squeeze the inner slider 413, thereby improving the absorption effect through airflow compression.

[0046] S4. Climbing and Wind Resistance

[0047] Workers can enter the control room 8 through the climbing mechanism 6. When the climbing mechanism 6 encounters strong winds during the climbing process, the main climbing tube 602 will deform first, and relative displacement will occur between it and the windproof frame mechanism 4 and the support frame mechanism 5. At this time, the energy-absorbing spring 407 will deform according to the magnitude of the relative displacement, thereby absorbing the energy during the relative displacement and achieving buffering.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
