[0001] The present invention relates to the technical field of construction equipment, and particularly to a hanging basket for building construction. Background Art

[0002] With the development of modern engineering projects, super high-rise buildings have developed rapidly due to advantages such as less land use, low urban infrastructure costs, and the ability to improve the urban appearance. There are more and more super high-rise buildings, and the requirements for construction technology difficulty and quality are constantly increasing. The complexity and difficulty of construction technology management are also getting higher and higher. At present, the external decoration construction of super high-rise building projects in China generally adopts hanging basket construction. The hanging basket is a construction mechanical equipment for high-altitude operations in building engineering, and is used for curtain wall installation, exterior wall cleaning, etc.

[0003] At present, most hanging baskets for buildings use lifting equipment to raise or lower the basket body and move it on the outside of the building to facilitate the operation of construction workers. For example, the invention patents with publication numbers CN110485699A and CN107130785A both disclose a hanging basket for buildings. Most of the existing hanging baskets are the same as those in the above two patents, with a relatively simple structure. They are easily shaken by the influence of air flow in the air and cannot buffer the impact of air flow, which is not conducive to the operation of construction workers. Summary of the Invention

Detailed implementation manners

[0026] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described ones are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] Refer to Figures 1-6, a suspension basket for building construction, comprising: a lifting mechanism 1, a steel cable 2 and a basket body 3. The basket body 3 is connected to the lifting mechanism 1 through the steel cable 2. Brackets 4 are symmetrically and fixedly installed on both sides of the basket body 3. The bottom end of the steel cable 2 is fixedly connected to a hanging bracket 5. The bottom ends of the two brackets 4 are fixedly connected to the bottom end of the hanging bracket 5 through connecting parts 6. The basket body 3 is provided with a pneumatic component, a pressurizing component and a counter-pushing component. The pneumatic component includes a plurality of blades 18 and a turntable 19. The counter-pushing component includes a column 7, a conduit 14 and a guide plate 16. The column 7 is vertically and fixedly installed on the bottom side of the basket body 3. The conduit 14 is U-shaped and rotatably sleeved on the bottom end of the column 7. A nozzle 17 is opened on the outer side of the vertical section of the conduit 14 away from the column 7. The guide plate 16 is vertically and fixedly installed at the bottom of the conduit 14. The pressurizing component includes a turbine group, a sleeve 8 and a housing 9. The housing 9 is fixedly installed at the bottom of the basket body 3, and a pressurizing air cavity is formed inside. The bottom of the basket body 3 communicates with the pressurizing air cavity. The turbine group is arranged in the pressurizing air cavity. The pressurizing air cavity communicates with the conduit 14. The sleeve 8 is rotatably sleeved on the column 7. The turntable 19 is rotatably sleeved on the column 7 and fixedly connected to the bottom end of the sleeve 8. The plurality of blades 18 are all vertically and fixedly installed on the turntable 19 and are annularly distributed on the outer side of the basket body 3.

[0029] The basket body 3 is cylindrical, and a plurality of diversion holes 22 are opened on the side wall. The diversion holes 22 can reduce the overall weight of the basket body 3, and at the same time reduce the side area of the basket body 3, so that the stress area of the basket body 3 is reduced, and it is also convenient for gas to flow into the basket body 3.

[0030] The lifting mechanism 1 includes a front frame body 101, a rear frame body 102, a cross beam 103, an upper support column 104 and a winding device 105. The front frame body 101 and the rear frame body 102 are both vertically and fixedly installed at the bottom of the cross beam 103 and are fixedly connected to the top end of the building through bolt fasteners. The upper support column 104 is vertically and fixedly installed on the upper side of the cross beam 103. The winding device 105 is fixedly installed on the cross beam 103. One end of the steel cable 2 away from the basket body 3 is connected to the winding device 105. Pulleys are installed at the front end of the cross beam 103 and the top end of the upper support column 104. The steel cable 2 is embedded outside the pulleys. A plurality of counterweight blocks 106 are provided on the rear frame body 102.

[0031] The sleeve 8 is rotatably sleeved inside the housing 9 through a first sealing bearing 10. The conduit 14 is connected to the bottom of the column 7 through a second sealing bearing 15, ensuring sealing while realizing rotation.

[0032] A plurality of first air holes 11 are vertically formed at the bottom of the basket body 3. A plurality of second air holes 12 are formed on the outer side of the sleeve 8. The inside of the column 7 is hollow, and a plurality of third air holes 13 are formed on the outer side. At any time, at least one second air hole 12 and one third air hole 13 are in a conducting state. The conduit 14 is in communication with the inside of the column 7, and the end far away from the column 7 is closed. The first air holes 11, the second air holes 12 and the third air holes 13 are in communication, ensuring that air flows into the conduit 14 and is ejected through the nozzle 17. At the same time, the flow of air can suck in the sand left at the bottom of the basket body 3 due to the transportation of building materials, and finally be discharged through the nozzle 17 and scattered away from the construction workers along the wind direction, which can ensure the cleanliness inside the basket body 3 and avoid the residual sand from interfering with the operation of the construction workers.

[0033] The turbine group is arranged on the sleeve 8 and is located inside the housing 9. The pressurizing component further includes two ratchets 20 and two ball bearings 21. The turbine group includes two turbines 23. The two ratchets 20 are both fixedly sleeved on the sleeve 8. The two turbines 23 are respectively fixedly sleeved on the two ratchets 20, and their flow guiding directions are opposite. The outer rings of the two ball bearings 21 are fixedly sleeved on the inner wall of the housing 9. The outer ends of the two turbines 23 are respectively fixedly connected to the inner rings of the two ball bearings 21. The ratchet 20 includes an outer ring and an inner ring. The inner ring is rotatably sleeved in the outer ring, and elastic blocks are fixedly embedded on the outer side. A plurality of card slots are formed on the inner wall of the outer ring. The elastic blocks cooperate with the card slots, so that the inner ring and the outer ring can only transmit torque in one direction, and the one-way rotation directions of the two ratchets 20 are opposite. When the sleeve 8 rotates in a certain direction, only one ratchet 20 can transmit torque. During the rotation of the sleeve 8, the torque is transmitted to the turbine 23 through the ratchet 20. However, the two turbines 23 are installed in a form with opposite flow guiding directions, and only one can rotate. That is, when the flow guiding direction of the turbine 23 is to guide the air flow downward, the inner ring and the outer ring of the ratchet 20 inside it rotate simultaneously, transmitting the torque of the sleeve 8 to the turbine 23, and the turbine 23 rotates to conduct downward pressurized flow guiding on the air flow. While the inner ring of the ratchet 20 inside the other upwardly guiding turbine 23 rotates with the sleeve 8, and the outer ring does not rotate, being in a slipping state and not transmitting the torque of the sleeve 8 to the turbine 23. Similarly, when the sleeve 8 rotates in the reverse direction, the operating conditions of the two turbines 23 are exchanged, ensuring that the flow direction of the air flow is always downward.

[0034] The resistance of the ball bearing 21 itself is greater than the frictional force between the elastic block and the inner wall of the outer ring, which can realize the slipping of the ratchet 20 and prevent the upwardly guiding turbine 23 from rotating with the sleeve 8, cutting off the torque of the sleeve 8, and ensuring that only the downwardly exhausting turbine 23 rotates, thereby realizing the control of the flow direction of the pressurized gas.

[0035] When using this device, the lifting mechanism 1 can be pre-mounted on the top of the building where construction is required to adjust the position of the basket 3. When used in the air, the airflow will impact the basket 3, and the impact of the airflow will cause multiple blades 18 to drive the turntable 19 to rotate. The turntable 19 drives the sleeve 8 to rotate, and the sleeve 8 drives the turbine 23 to rotate. The turbine 23 pressurizes the gas in the housing 9 and presses it into the column 7 through the second air hole 12 and the third air hole 13, and finally sprays out from the nozzle 17 of the conduit 14. Under the action of the guide plate 16, the conduit 14 is always deflected to the rear of the wind direction. After the pressurized gas sprays out from the nozzle 17, under the recoil action, a thrust opposite to the airflow impact force is applied to the basket 3, thereby buffering the impact force of the airflow and preventing the basket 3 from shaking greatly due to the airflow impact force, improving safety and facilitating the operation of construction workers.

[0036] The guide plate 16 can make the conduit 14 change with the wind direction, so that the nozzle 17 is always located on the leeward side, and thus the pressurized airflow S is sprayed out. After the pressurized airflow S is sprayed out, under the recoil action, a thrust F opposite to the wind direction can be generated.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
