[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the present invention provides a high-altitude hanging basket anti-strong wind device, including: a first piston part 2 and a first suction cup part 3.

[0024] This device also comprises a hanging basket 1 except comprising the first piston part 2 and the first sucker part 3, and it is used for placing or storing articles. Certainly, the hanging basket 1 can also accommodate the construction workers' construction standing.

[0025] The first piston portion 2 has a piston cavity 20, in which a piston 21 is disposed. A portion of the piston 21 extends out of the piston cavity 20 to form an operating end 210. The operating end 210 can be locked to the piston cavity 20 to maintain a constant negative pressure within the piston cavity 20. One end of the first piston portion 2 is connected to the hanging basket 1. By controlling the position of the piston 21 in the piston cavity 20, the negative pressure within the piston cavity 20 can be adjusted. Since the operating end 210 can be locked to the piston cavity 20, it can ensure that the position of the piston 21 in the piston cavity 20 remains unchanged, that is, the negative pressure within the piston cavity 20 remains constant.

[0026] The first suction cup portion 3 is connected to the other end of the first piston portion 2 to provide suction to the first suction cup portion 3. The first piston portion 2 provides suction to the first suction cup portion 3, allowing the first suction cup portion 3 to be tightly attached to the construction target. Since the operating end 210 can be locked with the outer wall of the piston cavity 20, the negative pressure in the piston cavity 20 remains constant, allowing the first suction cup portion 3 to be tightly attached, thereby preventing the hanging basket 1 from falling and improving safety.

[0027] In one embodiment, the operating end 210 can be locked on the piston chamber 20 as a snap lock. It should be noted that in addition to the snap lock method, the present invention can also adopt a mechanical locking device: directly lock the piston 21 or the piston rod 211 by means of external or internal pins, bolts, etc. in the piston chamber 20 so that it cannot move. A hydraulic / pneumatic brake lock can also be used: using the pressure of the system, when locking is required, high-pressure fluid is introduced into one or more piston chambers 20 through a control valve, and the fluid pressure is used to prevent the piston 21 from moving in the piston chamber 20. This design can achieve remote control. A magnetic locking system can also be used: a strong magnet is embedded in the piston 21 or the piston chamber 20, and the piston 21 is locked or released by the attraction or repulsion of an external electromagnet. This design can respond quickly and is wear-free.

[0028] like Figure 2 As shown, in one embodiment, a sliding opening 22 is provided along the axial direction of the piston cavity 20, and a latch 23 is provided at the end of the sliding opening 22. One end of the piston 21 can extend from the sliding opening 22 to form an operating end 210. The operating end 210 moves along the sliding opening 22 until it reaches the latch 23 and is then turned so that it can be engaged with the latch 23 to lock the piston 21. By controlling the operating end 210 to move along the sliding opening 22, the piston 21 in the piston cavity 20 also moves, generating negative pressure in the piston cavity 20 until the operating end 210 slides out of the sliding opening 22 and engages with the latch 23, achieving locking. When the operating end 210 is not opened, the piston 21 in the piston cavity 20 always remains in a fixed position in the piston cavity 20, that is, the negative pressure in the piston cavity 20 also remains unchanged, and the possibility of negative pressure gas leakage inside the first suction cup portion 3 will not occur. This avoids the problem of the piston 21 changing its position in the piston cavity 20 due to extreme weather, thereby improving safety. In addition, in an emergency, the quick-operation end 210 can be reset by opening the connection between the quick-operation end 210 and the bayonet 23, thereby quickly disconnecting the adsorption force of the first suction cup portion 3, thereby ensuring that the hanging basket 1 can be quickly and safely evacuated when necessary. For example, in the event of a fire or other emergency, the operator can quickly descend to a safe area. It should be noted that when the operation end rotates, the plug rod 211 away from the operation end 210 can rotate relative to the plug head 212, and the plug head 212 can remain stationary, so that the operation end 210 can be stuck on the bayonet 23. When the bayonet 23 is no longer needed to be stuck, the operation end 210 is rotated to its original position.

[0029] In one embodiment, the first piston portion 2 includes a piston 21 shell, one end of the outer wall of the piston 21 shell is connected to the hanging basket 1, and the other end is connected to the first suction cup portion 3. The piston 21 shell is provided with a piston cavity 20, and the sliding port 22 and the bayonet 23 are both provided on the piston 21 shell. Optionally, the piston 21 shell is a piston steel tube, and one side of the hanging basket 1 is fixed with a piston steel tube with a movable bearing so that the piston steel tube can be adjusted up and down relative to the hanging basket 1. It should be noted that the piston 21 is usually made of high-strength, wear-resistant materials, such as alloy steel, aluminum alloy or engineering plastics, depending on the pressure and temperature requirements of the application environment and the type of medium (oil, gas, etc.).

[0030] In one embodiment, the piston 21 includes a plug rod 211 and a plug head 212 connected to each other. The plug head 212 is arranged in the piston cavity 20 and close to the first suction cup portion 3. A portion of the plug rod 211 away from the plug head 212 extends out of the piston cavity 20 through the sliding opening 22. It should be noted that a portion of the plug rod 211 away from the plug head 212 extends out of the piston 21 through the sliding opening 22 to form an operating end 210, that is, a portion of the plug rod 211 away from the plug head 212 can be regarded as the operating end 210. The plug head 212 is driven to move in the piston cavity 20 by controlling the plug rod 211. When the plug rod 211 slides out of the sliding opening 22 and is clamped on the buckle, the plug head 212 always maintains its position in the piston cavity 20. Optionally, a buffer can be installed at the end of the plug head 212 to absorb the impact energy when the piston 21 reaches the end of the stroke to protect it from damage.

[0031] In one embodiment, the plug rod 211 is a straight structure within the piston cavity 20, and is bent within the sliding opening 22. The straight structure within the piston cavity 20 facilitates the movement of the plug head 212, and the bent structure of the plug rod 211 within the sliding opening 22 facilitates the locking of the plug rod 211 with the bayonet 23 when the plug rod 211 slides out of the sliding opening 22 to the bayonet 23. It should be noted that the turning angle of the bent structure of the plug rod 211 is designed according to actual design requirements and can be a right angle, an acute angle, or an obtuse angle. Regardless of the angle, it must be able to achieve locking cooperation with the bayonet 23.

[0032] In one embodiment, the piston 21 further includes a sealing ring, which is mounted on the plug head 212 and contacts the inner wall of the piston chamber 20. The sealing ring ensures that the working medium (such as oil or gas) does not leak from the gap between the piston 21 and the cylinder wall when the piston 21 moves, thereby improving the sealing performance and preventing air leakage from the piston chamber 20. Optionally, the sealing ring is an O-ring, a V-ring, or a combination of seals.

[0033] like Figure 3As shown, in one embodiment, the suction surface of the first suction cup portion 3 is an elastically deformable surface. It should be noted that in order for the suction cup to better conform to the contours of the object's surface and form a good seal even on irregular or slightly uneven surfaces, the suction surface is elastically deformable, but this surface needs to be flexible. To ensure a good seal, the edge of the suction surface of the first suction cup portion 3 is often designed with an elastic sealing ring or a special shape to increase the contact tightness with the suctioned surface and prevent air leakage. It should be noted that the suction surface of the first suction cup portion 3 has multiple suction holes. The suction principle is that when the suction cup contacts the surface of an object and the vacuum pump is activated to extract air, a negative pressure state is formed inside the suction cup, and the external atmospheric pressure presses the object toward the suction cup surface, thereby achieving a strong suction effect. The multiple suction holes on the suction surface increase the surface area of ​​the suction cup, allowing more small areas to be in close contact with the suctioned object, forming an effective seal even on surfaces that are not completely flat, and improving the stability and reliability of suction.

[0034] In one embodiment, the elastically deformable surface is made of soft ceramic, soft rubber, and silicone. Through these elastically deformable surfaces, the first suction cup portion 3 can better conform to the contours of the object's surface, and can be well adsorbed even on irregular or slightly uneven surfaces. It should be noted that the core portion of the adsorption surface is usually composed of porous ceramic, soft rubber, silicone, or other polymer materials with open or closed microporous structures. These materials not only need to have good air permeability to facilitate the rapid establishment and release of vacuum, but also need to maintain sufficient mechanical strength and durability. The adsorption surface can be adsorbed on exterior walls of various materials and shapes, ensuring firm adsorption. In windy weather, if people are not evacuated in time, the hanging basket 1 will not shake, thereby ensuring the safety of people. In addition to being windproof, the first suction cup portion 3 can also integrate other functions, such as serving as a safety anchor point, a tool mounting point, or auxiliary climbing equipment, to improve the versatility and efficiency of the hanging basket 1 operation. As a hanging point, because the adsorption force is sufficient, it can be detached from the hanging basket 1 and adsorbed on the wall.

[0035] In one embodiment, it also includes: a second piston portion 4 and a second suction cup portion 5 connected to each other, one end of the second piston portion 4 is connected to the hanging basket 1, the second piston portion 4 and the first piston portion 2 have the same structure and are spaced apart, and the second suction cup portion 5 and the first suction cup portion 3 have the same structure and are spaced apart. It should be noted that the second suction cup portion 5 and the first suction cup portion 3 both adopt a modular design, and can also be flexibly configured according to the size of the hanging basket 1 and the characteristics of the work wall, which not only ensures the adsorption efficiency but also facilitates installation and maintenance. Since the second piston portion 4 and the first piston portion 2 have the same structure and therefore have the same functional effects, the second piston portion 4 will not be described here.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
